More specifically, it -is a dynamic checker that detects and warns about some uses of uninitialized -memory. - -Userspace programmers might be familiar with Valgrind's memcheck. The main -difference between memcheck and kmemcheck is that memcheck works for userspace -programs only, and kmemcheck works for the kernel only. The implementations -are of course vastly different. Because of this, kmemcheck is not as accurate -as memcheck, but it turns out to be good enough in practice to discover real -programmer errors that the compiler is not able to find through static -analysis. - -Enabling kmemcheck on a kernel will probably slow it down to the extent that -the machine will not be usable for normal workloads such as e.g. an -interactive desktop. kmemcheck will also cause the kernel to use about twice -as much memory as normal. For this reason, kmemcheck is strictly a debugging -feature. - - -Downloading ------------ - -As of version 2.6.31-rc1, kmemcheck is included in the mainline kernel. - - -Configuring and compiling -------------------------- - -kmemcheck only works for the x86 (both 32- and 64-bit) platform. A number of -configuration variables must have specific settings in order for the kmemcheck -menu to even appear in "menuconfig". These are: - -- ``CONFIG_CC_OPTIMIZE_FOR_SIZE=n`` - This option is located under "General setup" / "Optimize for size". - - Without this, gcc will use certain optimizations that usually lead to - false positive warnings from kmemcheck. An example of this is a 16-bit - field in a struct, where gcc may load 32 bits, then discard the upper - 16 bits. kmemcheck sees only the 32-bit load, and may trigger a - warning for the upper 16 bits (if they're uninitialized). - -- ``CONFIG_SLAB=y`` or ``CONFIG_SLUB=y`` - This option is located under "General setup" / "Choose SLAB - allocator". - -- ``CONFIG_FUNCTION_TRACER=n`` - This option is located under "Kernel hacking" / "Tracers" / "Kernel - Function Tracer" - - When function tracing is compiled in, gcc emits a call to another - function at the beginning of every function. This means that when the - page fault handler is called, the ftrace framework will be called - before kmemcheck has had a chance to handle the fault. If ftrace then - modifies memory that was tracked by kmemcheck, the result is an - endless recursive page fault. - -- ``CONFIG_DEBUG_PAGEALLOC=n`` - This option is located under "Kernel hacking" / "Memory Debugging" - / "Debug page memory allocations". - -In addition, I highly recommend turning on ``CONFIG_DEBUG_INFO=y``. This is also -located under "Kernel hacking". With this, you will be able to get line number -information from the kmemcheck warnings, which is extremely valuable in -debugging a problem. This option is not mandatory, however, because it slows -down the compilation process and produces a much bigger kernel image. - -Now the kmemcheck menu should be visible (under "Kernel hacking" / "Memory -Debugging" / "kmemcheck: trap use of uninitialized memory"). Here follows -a description of the kmemcheck configuration variables: - -- ``CONFIG_KMEMCHECK`` - This must be enabled in order to use kmemcheck at all... - -- ``CONFIG_KMEMCHECK_``[``DISABLED`` | ``ENABLED`` | ``ONESHOT``]``_BY_DEFAULT`` - This option controls the status of kmemcheck at boot-time. "Enabled" - will enable kmemcheck right from the start, "disabled" will boot the - kernel as normal (but with the kmemcheck code compiled in, so it can - be enabled at run-time after the kernel has booted), and "one-shot" is - a special mode which will turn kmemcheck off automatically after - detecting the first use of uninitialized memory. - - If you are using kmemcheck to actively debug a problem, then you - probably want to choose "enabled" here. - - The one-shot mode is mostly useful in automated test setups because it - can prevent floods of warnings and increase the chances of the machine - surviving in case something is really wrong. In other cases, the one- - shot mode could actually be counter-productive because it would turn - itself off at the very first error -- in the case of a false positive - too -- and this would come in the way of debugging the specific - problem you were interested in. - - If you would like to use your kernel as normal, but with a chance to - enable kmemcheck in case of some problem, it might be a good idea to - choose "disabled" here. When kmemcheck is disabled, most of the run- - time overhead is not incurred, and the kernel will be almost as fast - as normal. - -- ``CONFIG_KMEMCHECK_QUEUE_SIZE`` - Select the maximum number of error reports to store in an internal - (fixed-size) buffer. Since errors can occur virtually anywhere and in - any context, we need a temporary storage area which is guaranteed not - to generate any other page faults when accessed. The queue will be - emptied as soon as a tasklet may be scheduled. If the queue is full, - new error reports will be lost. - - The default value of 64 is probably fine. If some code produces more - than 64 errors within an irqs-off section, then the code is likely to - produce many, many more, too, and these additional reports seldom give - any more information (the first report is usually the most valuable - anyway). - - This number might have to be adjusted if you are not using serial - console or similar to capture the kernel log. If you are using the - "dmesg" command to save the log, then getting a lot of kmemcheck - warnings might overflow the kernel log itself, and the earlier reports - will get lost in that way instead. Try setting this to 10 or so on - such a setup. - -- ``CONFIG_KMEMCHECK_SHADOW_COPY_SHIFT`` - Select the number of shadow bytes to save along with each entry of the - error-report queue. These bytes indicate what parts of an allocation - are initialized, uninitialized, etc. and will be displayed when an - error is detected to help the debugging of a particular problem. - - The number entered here is actually the logarithm of the number of - bytes that will be saved. So if you pick for example 5 here, kmemcheck - will save 2^5 = 32 bytes. - - The default value should be fine for debugging most problems. It also - fits nicely within 80 columns. - -- ``CONFIG_KMEMCHECK_PARTIAL_OK`` - This option (when enabled) works around certain GCC optimizations that - produce 32-bit reads from 16-bit variables where the upper 16 bits are - thrown away afterwards. - - The default value (enabled) is recommended. This may of course hide - some real errors, but disabling it would probably produce a lot of - false positives. - -- ``CONFIG_KMEMCHECK_BITOPS_OK`` - This option silences warnings that would be generated for bit-field - accesses where not all the bits are initialized at the same time. This - may also hide some real bugs. - - This option is probably obsolete, or it should be replaced with - the kmemcheck-/bitfield-annotations for the code in question. The - default value is therefore fine. - -Now compile the kernel as usual. - - -How to use ----------- - -Booting -~~~~~~~ - -First some information about the command-line options. There is only one -option specific to kmemcheck, and this is called "kmemcheck". It can be used -to override the default mode as chosen by the ``CONFIG_KMEMCHECK_*_BY_DEFAULT`` -option. Its possible settings are: - -- ``kmemcheck=0`` (disabled) -- ``kmemcheck=1`` (enabled) -- ``kmemcheck=2`` (one-shot mode) - -If SLUB debugging has been enabled in the kernel, it may take precedence over -kmemcheck in such a way that the slab caches which are under SLUB debugging -will not be tracked by kmemcheck. In order to ensure that this doesn't happen -(even though it shouldn't by default), use SLUB's boot option ``slub_debug``, -like this: ``slub_debug=-`` - -In fact, this option may also be used for fine-grained control over SLUB vs. -kmemcheck. For example, if the command line includes -``kmemcheck=1 slub_debug=,dentry``, then SLUB debugging will be used only -for the "dentry" slab cache, and with kmemcheck tracking all the other -caches. This is advanced usage, however, and is not generally recommended. - - -Run-time enable/disable -~~~~~~~~~~~~~~~~~~~~~~~ - -When the kernel has booted, it is possible to enable or disable kmemcheck at -run-time. WARNING: This feature is still experimental and may cause false -positive warnings to appear. Therefore, try not to use this. If you find that -it doesn't work properly (e.g. you see an unreasonable amount of warnings), I -will be happy to take bug reports. - -Use the file ``/proc/sys/kernel/kmemcheck`` for this purpose, e.g.:: - - $ echo 0 > /proc/sys/kernel/kmemcheck # disables kmemcheck - -The numbers are the same as for the ``kmemcheck=`` command-line option. - - -Debugging -~~~~~~~~~ - -A typical report will look something like this:: - - WARNING: kmemcheck: Caught 32-bit read from uninitialized memory (ffff88003e4a2024) - 80000000000000000000000000000000000000000088ffff0000000000000000 - i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u - ^ - - Pid: 1856, comm: ntpdate Not tainted 2.6.29-rc5 #264 945P-A - RIP: 0010:[] [] __dequeue_signal+0xc8/0x190 - RSP: 0018:ffff88003cdf7d98 EFLAGS: 00210002 - RAX: 0000000000000030 RBX: ffff88003d4ea968 RCX: 0000000000000009 - RDX: ffff88003e5d6018 RSI: ffff88003e5d6024 RDI: ffff88003cdf7e84 - RBP: ffff88003cdf7db8 R08: ffff88003e5d6000 R09: 0000000000000000 - R10: 0000000000000080 R11: 0000000000000000 R12: 000000000000000e - R13: ffff88003cdf7e78 R14: ffff88003d530710 R15: ffff88003d5a98c8 - FS: 0000000000000000(0000) GS:ffff880001982000(0063) knlGS:00000 - CS: 0010 DS: 002b ES: 002b CR0: 0000000080050033 - CR2: ffff88003f806ea0 CR3: 000000003c036000 CR4: 00000000000006a0 - DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 - DR3: 0000000000000000 DR6: 00000000ffff4ff0 DR7: 0000000000000400 - [] dequeue_signal+0x8e/0x170 - [] get_signal_to_deliver+0x98/0x390 - [] do_notify_resume+0xad/0x7d0 - [] int_signal+0x12/0x17 - [] 0xffffffffffffffff - -The single most valuable information in this report is the RIP (or EIP on 32- -bit) value.

Here -they are: - -- ``__GFP_NOTRACK_FALSE_POSITIVE`` - This flag can be passed to ``kmalloc()`` or ``kmem_cache_alloc()`` - (therefore also to other functions that end up calling one of - these) to indicate that the allocation should not be tracked - because it would lead to a false positive report. This is a "big - hammer" way of silencing kmemcheck; after all, even if the false - positive pertains to particular field in a struct, for example, we - will now lose the ability to find (real) errors in other parts of - the same struct. - - Example:: - - /* No warnings will ever trigger on accessing any part of x */ - x = kmalloc(sizeof *x, GFP_KERNEL | __GFP_NOTRACK_FALSE_POSITIVE); - -- ``kmemcheck_bitfield_begin(name)``/``kmemcheck_bitfield_end(name)`` and - ``kmemcheck_annotate_bitfield(ptr, name)`` - The first two of these three macros can be used inside struct - definitions to signal, respectively, the beginning and end of a - bitfield. Additionally, this will assign the bitfield a name, which - is given as an argument to the macros. - - Having used these markers, one can later use - kmemcheck_annotate_bitfield() at the point of allocation, to indicate - which parts of the allocation is part of a bitfield. - - Example:: - - struct foo { - int x; - - kmemcheck_bitfield_begin(flags); - int flag_a:1; - int flag_b:1; - kmemcheck_bitfield_end(flags); - - int y; - }; - - struct foo *x = kmalloc(sizeof *x); - - /* No warnings will trigger on accessing the bitfield of x */ - kmemcheck_annotate_bitfield(x, flags); - - Note that ``kmemcheck_annotate_bitfield()`` can be used even before the - return value of ``kmalloc()`` is checked -- in other words, passing NULL - as the first argument is legal (and will do nothing). - - -Reporting errors ----------------- - -As we have seen, kmemcheck will produce false positive reports. Therefore, it -is not very wise to blindly post kmemcheck warnings to mailing lists and -maintainers. Instead, I encourage maintainers and developers to find errors -in their own code.

Most -developers know their own code and will quickly and efficiently determine the -root cause of a kmemcheck report. This is therefore also the most efficient -way to work with kmemcheck. - -That said, we (the kmemcheck maintainers) will always be on the lookout for -false positives that we can annotate and silence. So whatever you find, -please drop us a note privately! Kernel configs and steps to reproduce (if -available) are of course a great help too. - -Happy hacking! - - -Technical description ---------------------- - -kmemcheck works by marking memory pages non-present. This means that whenever -somebody attempts to access the page, a page fault is generated.

This way, the -interrupted code can continue as usual. - -But after the instruction has been executed, we should hide the page again, so -that we can catch the next access too! Now kmemcheck makes use of a debugging -feature of the processor, namely single-stepping.

When +the kernel is entered via syscalls, interrupts or exceptions, the +page tables are switched to the full "kernel" copy. When the system +switches back to user mode, the user copy is used again. + +The userspace page tables contain only a minimal amount of kernel +data: only what is needed to enter/exit the kernel such as the +entry/exit functions themselves and the interrupt descriptor table +(IDT). There are a few strictly unnecessary things that get mapped +such as the first C function when entering an interrupt (see +comments in pti.c). + +This approach helps to ensure that side-channel attacks leveraging +the paging structures do not function when PTI is enabled. It can be +enabled by setting CONFIG_PAGE_TABLE_ISOLATION=y at compile time. +Once enabled at compile-time, it can be disabled at boot with the +'nopti' or 'pti=' kernel parameters (see kernel-parameters.txt). + +Page Table Management +===================== + +When PTI is enabled, the kernel manages two sets of page tables. +The first set is very similar to the single set which is present in +kernels without PTI. This includes a complete mapping of userspace +that the kernel can use for things like copy_to_user(). + +Although _complete_, the user portion of the kernel page tables is +crippled by setting the NX bit in the top level. This ensures +that any missed kernel->user CR3 switch will immediately crash +userspace upon executing its first instruction. + +The userspace page tables map only the kernel data needed to enter +and exit the kernel. This data is entirely contained in the 'struct +cpu_entry_area' structure which is placed in the fixmap which gives +each CPU's copy of the area a compile-time-fixed virtual address. + +For new userspace mappings, the kernel makes the entries in its +page tables like normal. The only difference is when the kernel +makes entries in the top (PGD) level. In addition to setting the +entry in the main kernel PGD, a copy of the entry is made in the +userspace page tables' PGD. + +This sharing at the PGD level also inherently shares all the lower +layers of the page tables. This leaves a single, shared set of +userspace page tables to manage. One PTE to lock, one set of +accessed bits, dirty bits, etc... + +Overhead +======== + +Protection against side-channel attacks is important. But, +this protection comes at a cost: + +1. Increased Memory Use + a. Each process now needs an order-1 PGD instead of order-0. + (Consumes an additional 4k per process). + b. The 'cpu_entry_area' structure must be 2MB in size and 2MB + aligned so that it can be mapped by setting a single PMD + entry. This consumes nearly 2MB of RAM once the kernel + is decompressed, but no space in the kernel image itself. + +2. Runtime Cost + a. CR3 manipulation to switch between the page table copies + must be done at interrupt, syscall, and exception entry + and exit (it can be skipped when the kernel is interrupted, + though.) Moves to CR3 are on the order of a hundred + cycles, and are required at every entry and exit. + b. A "trampoline" must be used for SYSCALL entry. This + trampoline depends on a smaller set of resources than the + non-PTI SYSCALL entry code, so requires mapping fewer + things into the userspace page tables. The downside is + that stacks must be switched at entry time. + c. Global pages are disabled for all kernel structures not + mapped into both kernel and userspace page tables. This + feature of the MMU allows different processes to share TLB + entries mapping the kernel. Losing the feature means more + TLB misses after a context switch. The actual loss of + performance is very small, however, never exceeding 1%. + d. Process Context IDentifiers (PCID) is a CPU feature that + allows us to skip flushing the entire TLB when switching page + tables by setting a special bit in CR3 when the page tables + are changed. This makes switching the page tables (at context + switch, or kernel entry/exit) cheaper. But, on systems with + PCID support, the context switch code must flush both the user + and kernel entries out of the TLB. The user PCID TLB flush is + deferred until the exit to userspace, minimizing the cost. + See intel.com/sdm for the gory PCID/INVPCID details. + e. The userspace page tables must be populated for each new + process. Even without PTI, the shared kernel mappings + are created by copying top-level (PGD) entries into each + new process. But, with PTI, there are now *two* kernel + mappings: one in the kernel page tables that maps everything + and one for the entry/exit structures. At fork(), we need to + copy both. + f. In addition to the fork()-time copying, there must also + be an update to the userspace PGD any time a set_pgd() is done + on a PGD used to map userspace. This ensures that the kernel + and userspace copies always map the same userspace + memory. + g. On systems without PCID support, each CR3 write flushes + the entire TLB. That means that each syscall, interrupt + or exception flushes the TLB. + h. INVPCID is a TLB-flushing instruction which allows flushing + of TLB entries for non-current PCIDs. Some systems support + PCIDs, but do not support INVPCID. On these systems, addresses + can only be flushed from the TLB for the current PCID. When + flushing a kernel address, we need to flush all PCIDs, so a + single kernel address flush will require a TLB-flushing CR3 + write upon the next use of every PCID. + +Possible Future Work +==================== +1. We can be more careful about not actually writing to CR3 + unless its value is actually changed. +2. Allow PTI to be enabled/disabled at runtime in addition to the + boot-time switching. + +Testing +======== + +To test stability of PTI, the following test procedure is recommended, +ideally doing all of these in parallel: + +1. Set CONFIG_DEBUG_ENTRY=y +2. Run several copies of all of the tools/testing/selftests/x86/ tests + (excluding MPX and protection_keys) in a loop on multiple CPUs for + several minutes. These tests frequently uncover corner cases in the + kernel entry code. In general, old kernels might cause these tests + themselves to crash, but they should never crash the kernel. +3. Run the 'perf' tool in a mode (top or record) that generates many + frequent performance monitoring non-maskable interrupts (see "NMI" + in /proc/interrupts). This exercises the NMI entry/exit code which + is known to trigger bugs in code paths that did not expect to be + interrupted, including nested NMIs.

Usually a bug in one of the + more obscure corners of entry_64.S + * Crashes in early boot, especially around CPU bringup. Bugs + in the trampoline code or mappings cause these. + * Crashes at the first interrupt. Caused by bugs in entry_64.S, + like screwing up a page table switch. Also caused by + incorrectly mapping the IRQ handler entry code. + * Crashes at the first NMI. The NMI code is separate from main + interrupt handlers and can have bugs that do not affect + normal interrupts. Also caused by incorrectly mapping NMI + code. NMIs that interrupt the entry code must be very + careful and can be the cause of crashes that show up when + running perf. + * Kernel crashes at the first exit to userspace. entry_64.S + bugs, or failing to map some of the exit code. + * Crashes at first interrupt that interrupts userspace. The paths + in entry_64.S that return to userspace are sometimes separate + from the ones that return to the kernel. + * Double faults: overflowing the kernel stack because of page + faults upon page faults. Caused by touching non-pti-mapped + data in the entry code, or forgetting to switch to kernel + CR3 before calling into C functions which are not pti-mapped. + * Userspace segfaults early in boot, sometimes manifesting + as mount(8) failing to mount the rootfs. These have + tended to be TLB invalidation issues.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) 19yy + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

hostapd MLME (e.g., nl80211) + +2010-01-16 - v0.7.1 + * cleaned up driver wrapper API (struct wpa_driver_ops); the new API + is not fully backwards compatible, so out-of-tree driver wrappers + will need modifications + * cleaned up various module interfaces + * merge hostapd and wpa_supplicant developers' documentation into a + single document + * fixed HT Capabilities IE with nl80211 drivers + * moved generic AP functionality code into src/ap + * WPS: handle Selected Registrar as union of info from all Registrars + * remove obsolte Prism54.org driver wrapper + * added internal debugging

implementations that drop EAPOL frames which use version number 2 + [Bug 89] + * added support for EAP-SAKE (no EAP method number allocated yet, so + this is using the same experimental type 255 as EAP-PSK) + * fixed EAP-MSCHAPv2 message length validation + +2006-03-19 - v0.5.2 + * fixed stdarg use in hostapd_logger(): if both stdout and syslog + logging was enabled, hostapd could trigger a segmentation fault in + vsyslog on some CPU -- C library combinations + * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external + program to make it easier to use for implementing real SS7 gateway; + eap_sim_db is not anymore used as a file name for GSM authentication + triplets; instead, it is path to UNIX domain socket that will be used + to communicate with the external gateway program (e.g., hlr_auc_gw) + * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses + local information (GSM authentication triplets from a text file and + hardcoded AKA authentication data); this can be used to test EAP-SIM + and EAP-AKA + * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw + to make it possible to test EAP-AKA with real USIM cards (this is + disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw + to enable this) + * driver_madwifi: added support for getting station RSN IE from + madwifi-ng svn r1453 and newer; this fixes

driver_madwifi: fixed EAPOL packet receive for configuration where + ath# is part of a bridge interface + * added a configuration file and log analyzer script for logwatch + * fixed EAPOL state machine step function to process all state + transitions before processing new events; this resolves a race + condition in which EAPOL-Start message could trigger hostapd to send + two

only after returning from + the real signal handler + * reset sta->timeout_next after successful association to make sure + that the previously registered inactivity timer will not remove the + STA immediately (e.g., if STA deauthenticates and re-associates + before the timer is triggered). + * added new hostapd.conf variable, nas_identifier, that can be used to + add an optional RADIUS Attribute, NAS-Identifier, into authentication + and accounting messages + * added support for Accounting-On and Accounting-Off messages + * fixed accounting session handling to send Accounting-Start only once + per session and not to send Accounting-Stop if the session was not + initialized properly + * fixed Accounting-Stop statistics in cases where the message was + previously sent after the

It adds more features to the basic IEEE 802.11 management +included in the kernel driver: using external RADIUS authentication +server for MAC address based access control, IEEE 802.1X Authenticator +and dynamic WEP keying, RADIUS accounting, WPA/WPA2 (IEEE 802.11i/RSN) +Authenticator and dynamic TKIP/CCMP keying. + +The current version includes support for other drivers, an integrated +EAP server (i.e., allow full authentication without requiring +an external RADIUS authentication server), and RADIUS authentication +server for EAP authentication. + + +Requirements +------------ + +Current hardware/software requirements: +- drivers: + Host AP driver for Prism2/2.5/3. + (http://hostap.epitest.fi/) + Please note that station firmware version needs to be 1.7.0 or newer + to work in WPA mode. + + madwifi driver for cards based on Atheros chip set (ar521x) + (http://sourceforge.net/projects/madwifi/) + Please note that you will need to add the correct path for + madwifi driver root directory in .config (see defconfig file for + an example: CFLAGS += -I) + + mac80211-based drivers that support AP mode (with driver=nl80211). + This includes drivers for Atheros (ath9k) and Broadcom (b43) + chipsets. + + Any wired Ethernet driver for wired IEEE 802.1X authentication + (experimental code) + + FreeBSD -current (with some kernel mods that have not yet been + committed when hostapd v0.3.0 was released) + BSD net80211 layer (e.g., Atheros driver) + + +Build configuration +------------------- + +In order to be able to build hostapd, you will need to create a build +time configuration file, .config that selects which optional +components are included. See defconfig file for example configuration +and list of available options. + + + +IEEE 802.1X +=========== + +IEEE Std 802.1X-2001 is a standard for port-based network access +control. In case of IEEE 802.11 networks, a "virtual port" is used +between each associated station and the AP. IEEE 802.11 specifies +minimal authentication mechanism for stations, whereas IEEE 802.1X +introduces a extensible mechanism for authenticating and authorizing +users. + +IEEE 802.1X uses elements called Supplicant, Authenticator, Port +Access Entity, and Authentication Server. Supplicant is a component in +a station and it performs the authentication with the Authentication +Server. An access point includes an Authenticator that relays the packets +between a Supplicant and an Authentication Server. In addition, it has a +Port Access Entity (PAE) with Authenticator functionality for +controlling the virtual port authorization, i.e., whether to accept +packets from or to the station. + +IEEE 802.1X uses Extensible Authentication Protocol (EAP). The frames +between a Supplicant and an Authenticator are sent using EAP over LAN +(EAPOL) and the Authenticator relays these frames to the Authentication +Server (and similarly, relays the messages from the Authentication +Server to the Supplicant). The Authentication Server can be colocated with the +Authenticator, in which case there is no need for additional protocol +for EAP frame transmission. However, a more common configuration is to +use an external Authentication Server and encapsulate EAP frame in the +frames used by that server. RADIUS is suitable for this, but IEEE +802.1X would also allow other mechanisms. + +Host AP driver includes PAE functionality in the kernel driver. It +is a relatively simple mechanism for denying normal frames going to +or coming from an unauthorized port. PAE allows IEEE 802.1X related +frames to be passed between the Supplicant and the Authenticator even +on an unauthorized port. + +User space daemon, hostapd, includes Authenticator functionality. It +receives 802.1X (EAPOL) frames from the Supplicant using the wlan#ap +device that is also used with IEEE 802.11 management frames. The +frames to the Supplicant are sent using the same device. + +The normal configuration of the Authenticator would use an external +Authentication Server. hostapd supports RADIUS encapsulation of EAP +packets, so the Authentication Server should be a RADIUS server, like +FreeRADIUS (http://www.freeradius.org/). The Authenticator in hostapd +relays the frames between the Supplicant and the Authentication +Server. It also controls the PAE functionality in the kernel driver by +controlling virtual port authorization, i.e., station-AP +connection, based on the IEEE 802.1X state. + +When a station would like to use the services of an access point, it +will first perform IEEE 802.11 authentication. This is normally done +with open systems authentication, so there is no security. After +this, IEEE 802.11 association is performed. If IEEE 802.1X is +configured to be used, the virtual port for the station is set in +Unauthorized state and only IEEE 802.1X frames are accepted at this +point. The Authenticator will then ask the Supplicant to authenticate +with the Authentication Server. After this is completed successfully, +the virtual port is set to Authorized state and frames from and to the +station are accepted. + +Host AP configuration for IEEE 802.1X +------------------------------------- + +The user space daemon has its own configuration file that can be used to +define AP options. Distribution package contains an example +configuration file (hostapd/hostapd.conf) that can be used as a basis +for configuration. It includes examples of all supported configuration +options and short description of each option. hostapd should be started +with full path to the configuration file as the command line argument, +e.g., './hostapd /etc/hostapd.conf'. If you have more that one wireless +LAN card, you can use one hostapd process for multiple interfaces by +giving a list of configuration files (one per interface) in the command +line. + +hostapd includes a minimal co-located IEEE 802.1X server which can be +used to test IEEE 802.1X authentication. However, it should not be +used in normal use since it does not provide any security. This can be +configured by setting ieee8021x and minimal_eap options in the +configuration file. + +An external Authentication Server (RADIUS) is configured with +auth_server_{addr,port,shared_secret} options. In addition, +ieee8021x and own_ip_addr must be set for this mode. With such +configuration, the co-located Authentication Server is not used and EAP +frames will be relayed using EAPOL between the Supplicant and the +Authenticator and RADIUS encapsulation between the Authenticator and +the Authentication Server. Other than this, the functionality is similar +to the case with the co-located Authentication Server. + +Authentication Server and Supplicant +------------------------------------ + +Any RADIUS server supporting EAP should be usable as an IEEE 802.1X +Authentication Server with hostapd Authenticator. FreeRADIUS +(http://www.freeradius.org/) has been successfully tested with hostapd +Authenticator and both Xsupplicant (http://www.open1x.org) and Windows +XP Supplicants. EAP/TLS was used with Xsupplicant and +EAP/MD5-Challenge with Windows XP. + +http://www.missl.cs.umd.edu/wireless/eaptls/ has useful information +about using EAP/TLS with FreeRADIUS and Xsupplicant (just replace +Cisco access point with Host AP driver, hostapd daemon, and a Prism2 +card ;-). http://www.freeradius.org/doc/EAP-MD5.html has information +about using EAP/MD5 with FreeRADIUS, including instructions for WinXP +configuration. http://www.denobula.com/EAPTLS.pdf has a HOWTO on +EAP/TLS use with WinXP Supplicant. + +Automatic WEP key configuration +------------------------------- + +EAP/TLS generates a session key that can be used to send WEP keys from +an AP to authenticated stations. The Authenticator in hostapd can be +configured to automatically select a random default/broadcast key +(shared by all authenticated stations) with wep_key_len_broadcast +option (5 for 40-bit WEP or 13 for 104-bit WEP). In addition, +wep_key_len_unicast option can be used to configure individual unicast +keys for stations. This requires support for individual keys in the +station driver. + +WEP keys can be automatically updated by configuring rekeying. This +will improve security of the network since same WEP key will only be +used for a limited period of time. wep_rekey_period option sets the +interval for rekeying in seconds. + + +WPA/WPA2 +======== + +Features +-------- + +Supported WPA/IEEE 802.11i features: +- WPA-PSK ("WPA-Personal") +- WPA with EAP (e.g., with RADIUS authentication server) ("WPA-Enterprise") +- key management for CCMP, TKIP, WEP104, WEP40 +- RSN/WPA2 (IEEE 802.11i), including PMKSA caching and pre-authentication + +WPA +--- + +The original security mechanism of IEEE 802.11 standard was not +designed to be strong and has proved to be insufficient for most +networks that require some kind of security. Task group I (Security) +of IEEE 802.11 working group (http://www.ieee802.org/11/) has worked +to address the flaws of the base standard and has in practice +completed its work in May 2004. The IEEE 802.11i amendment to the IEEE +802.11 standard was approved in June 2004 and this amendment is likely +to be published in July 2004. + +Wi-Fi Alliance (http://www.wi-fi.org/) used a draft version of the +IEEE 802.11i work (draft 3.0) to define a subset of the security +enhancements that can be implemented with existing wlan hardware. This +is called Wi-Fi Protected Access (WPA). This has now become a +mandatory component of interoperability testing and certification done +by Wi-Fi Alliance. Wi-Fi provides information about WPA at its web +site (http://www.wi-fi.org/OpenSection/protected_access.asp). + +IEEE 802.11 standard defined wired equivalent privacy (WEP) algorithm +for protecting wireless networks. WEP uses RC4 with 40-bit keys, +24-bit initialization vector (IV), and CRC32 to protect against packet +forgery. All these choices have proven to be insufficient: key space is +too small against current attacks, RC4 key scheduling is insufficient +(beginning of the pseudorandom stream should be skipped), IV space is +too small and IV reuse makes attacks easier, there is no replay +protection, and non-keyed authentication does not protect against bit +flipping packet data. + +WPA is an intermediate solution for the security issues. It uses +Temporal Key Integrity Protocol (TKIP) to replace WEP. TKIP is a +compromise on strong security and possibility to use existing +hardware. It still uses RC4 for the encryption like WEP, but with +per-packet RC4 keys. In addition, it implements replay protection, +keyed packet authentication mechanism (Michael MIC). + +Keys can be managed using two different mechanisms. WPA can either use +an external authentication server (e.g., RADIUS) and EAP just like +IEEE 802.1X is using or pre-shared keys without need for additional +servers. Wi-Fi calls these "WPA-Enterprise" and "WPA-Personal", +respectively. Both mechanisms will generate a master session key for +the Authenticator (AP) and Supplicant (client station). + +WPA implements a new key handshake (4-Way Handshake and Group Key +Handshake) for generating and exchanging data encryption keys between +the Authenticator and Supplicant. This handshake is also used to +verify that both Authenticator and Supplicant know the master session +key. These handshakes are identical regardless of the selected key +management mechanism (only the method for generating master session +key changes). + + +IEEE 802.11i / WPA2 +------------------- + +The design for parts of IEEE 802.11i that were not included in WPA has +finished (May 2004) and this amendment to IEEE 802.11 was approved in +June 2004. Wi-Fi Alliance is using the final IEEE 802.11i as a new +version of WPA called WPA2. This includes, e.g., support for more +robust encryption algorithm (CCMP: AES in Counter mode with CBC-MAC) +to replace TKIP and optimizations for handoff (reduced number of +messages in initial key handshake, pre-authentication, and PMKSA caching). + +Some wireless LAN vendors are already providing support for CCMP in +their WPA products. There is no "official" interoperability +certification for CCMP and/or mixed modes using both TKIP and CCMP, so +some interoperability issues can be expected even though many +combinations seem to be working with equipment from different vendors. +Testing for WPA2 is likely to start during the second half of 2004. + +hostapd configuration for WPA/WPA2 +---------------------------------- + +TODO + +# Enable WPA.

It allows automated generation of random keys (WPA +passphrase/PSK) and configuration of an access point and client +devices. WPS includes number of methods for setting up connections +with PIN method and push-button configuration (PBC) being the most +commonly deployed options. + +While WPS can enable more home networks to use encryption in the +wireless network, it should be noted that the use of the PIN and +especially PBC mechanisms for authenticating the initial key setup is +not very secure. As such, use of WPS may not be suitable for +environments that require secure network access without chance for +allowing outsiders to gain access during the setup phase. + +WPS uses following terms to describe the entities participating in the +network setup: +- access point: the WLAN access point +- Registrar: a device that control a network and can authorize + addition of new devices); this may be either in the AP ("internal + Registrar") or in an external device, e.g., a laptop, ("external + Registrar") +- Enrollee: a device that is being authorized to use the network + +It should also be noted that the AP and a client device may change +roles (i.e., AP acts as an Enrollee and client device as a Registrar) +when WPS is used to configure the access point. + + +More information about WPS is available from Wi-Fi Alliance: +http://www.wi-fi.org/wifi-protected-setup + + +hostapd implementation +---------------------- + +hostapd includes an optional WPS component that can be used as an +internal WPS Registrar to manage addition of new WPS enabled clients +to the network. In addition, WPS Enrollee functionality in hostapd can +be used to allow external WPS Registrars to configure the access +point, e.g., for initial network setup. In addition, hostapd can proxy a +WPS registration between a wireless Enrollee and an external Registrar +(e.g., Microsoft Vista or Atheros JumpStart) with UPnP. + + +hostapd configuration +--------------------- + +WPS is an optional component that needs to be enabled in hostapd build +configuration (.config).

"hostapd_cli wps_check_pin " can be used to do such +processing. It returns FAIL if the PIN is invalid, or FAIL-CHECKSUM if +the checksum digit is incorrect, or the processed PIN (non-digit +characters removed) if the PIN is valid. + +When a client device (WPS Enrollee) connects to hostapd (WPS +Registrar) in order to start PIN mode negotiation for WPS, an +identifier (Enrollee UUID) is sent. hostapd will need to be configured +with a device password (PIN) for this Enrollee. This is an operation +that requires user interaction (assuming there are no pre-configured +PINs on the AP for a set of Enrollee). + +The PIN request with information about the device is appended to the +wps_pin_requests file (/var/run/hostapd.pin-req in this example). In +addition, hostapd control interface event is sent as a notification of +a new device. The AP could use, e.g., a web UI for showing active +Enrollees to the user and request a PIN for an Enrollee. + +The PIN request file has one line for every Enrollee that connected to +the AP, but for which there was no PIN. Following information is +provided for each Enrollee (separated with tabulators): +- timestamp (seconds from 1970-01-01) +- Enrollee UUID +- MAC address +- Device name +- Manufacturer +- Model Name +- Model Number +- Serial Number +- Device category + +Example line in the /var/run/hostapd.pin-req file: +1200188391 53b63a98-d29e-4457-a2ed-094d7e6a669c Intel(R) Centrino(R) Intel Corporation Intel(R) Centrino(R) - - 1-0050F204-1 + +Control interface data: +WPS-PIN-NEEDED [UUID-E|MAC Address|Device Name|Manufacturer|Model Name|Model Number|Serial Number|Device Category] +For example: +<2>WPS-PIN-NEEDED [53b63a98-d29e-4457-a2ed-094d7e6a669c|02:12:34:56:78:9a|Device|Manuf|Model|Model Number|Serial Number|1-0050F204-1] + +When the user enters a PIN for a pending Enrollee, e.g., on the web +UI), hostapd needs to be notified of the new PIN over the control +interface. This can be done either by using the UNIX domain socket +-based control interface directly (src/common/wpa_ctrl.c provides +helper functions for using the interface) or by calling hostapd_cli. + +Example command to add a PIN (12345670) for an Enrollee: + +hostapd_cli wps_pin 53b63a98-d29e-4457-a2ed-094d7e6a669c 12345670 + +If the UUID-E is not available (e.g., Enrollee waits for the Registrar +to be selected before connecting), wildcard UUID may be used to allow +the PIN to be used once with any UUID: + +hostapd_cli wps_pin any 12345670 + +To reduce likelihood of PIN being used with other devices or of +forgetting an active PIN available for potential attackers, expiration +time in seconds can be set for the new PIN (value 0 indicates no +expiration): + +hostapd_cli wps_pin any 12345670 300 + +If the MAC address of the enrollee is known, it should be configured +to allow the AP to advertise list of authorized enrollees: + +hostapd_cli wps_pin 53b63a98-d29e-4457-a2ed-094d7e6a669c \ + 12345670 300 00:11:22:33:44:55 + + +After this, the Enrollee can connect to the AP again and complete WPS +negotiation. At that point, a new, random WPA PSK is generated for the +client device and the client can then use that key to connect to the +AP to access the network. + + +If the AP includes a pushbutton, WPS PBC mode can be used. It is +enabled by pushing a button on both the AP and the client at about the +same time (2 minute window). hostapd needs to be notified about the AP +button pushed event over the control interface, e.g., by calling +hostapd_cli: + +hostapd_cli wps_pbc + +At this point, the client has two minutes to complete WPS negotiation +which will generate a new WPA PSK in the same way as the PIN method +described above. + + +When an external Registrar is used, the AP can act as an Enrollee and +use its AP PIN. A static AP PIN (e.g., one one a label in the AP +device) can be configured in hostapd.conf (ap_pin parameter). A more +secure option is to use hostapd_cli wps_ap_pin command to enable the +AP PIN only based on user action (and even better security by using a +random AP PIN for each session, i.e., by using "wps_ap_pin random" +command with a timeout value).

However, it is possible to +control these operations from external programs, if desired. + +The internal credential generation can be disabled with +skip_cred_build=1 option in the configuration. extra_cred option will +then need to be used to provide pre-configured Credential attribute(s) +for hostapd to use. The exact data from this binary file will be sent, +i.e., it will have to include valid WPS attributes. extra_cred can +also be used to add additional networks if the Registrar is used to +configure credentials for multiple networks. + +Processing of received configuration updates can be disabled with +wps_cred_processing=1 option. When this is used, an external program +is responsible for creating hostapd configuration files and processing +configuration updates based on messages received from hostapd over +control interface.

As an example + * if you are world roaming (regulatory domain set to world or if your + * driver is using a custom world roaming regulatory domain) and while + * doing a passive scan on the 5 GHz band you find an AP there (if not + * on a DFS channel) you will now be able to actively scan for that AP + * or use AP mode on your card on that same channel. Note that this will + * never be used for channels 1-11 on the 2 GHz band as they are always + * enabled world wide. This beacon hint is only sent if your device had + * either disabled active scanning or beaconing on a channel. We send to + * userspace the wiphy on which we removed a restriction from + * (%NL80211_ATTR_WIPHY) and the channel on which this occurred + * before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER) + * the beacon hint was processed. + * + * @NL80211_CMD_AUTHENTICATE: authentication request and notification. + * This command is used both as a command (request to authenticate) and + * as an event on the "mlme" multicast group indicating completion of the + * authentication process. + * When used as a command, %NL80211_ATTR_IFINDEX is used to identify the + * interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and + * BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify + * the SSID (mainly for association, but is included in authentication + * request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used + * to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE + * is used to specify the authentication type. %NL80211_ATTR_IE is used to + * define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs) + * to be added to the frame. + * When used as an event, this reports reception of an Authentication + * frame in station and IBSS modes when the local MLME processed the + * frame, i.e., it was for the local STA and was received in correct + * state. This is similar to MLME-AUTHENTICATE.confirm primitive in the + * MLME SAP interface (kernel providing MLME, userspace SME). The + * included %NL80211_ATTR_FRAME attribute contains the management frame + * (including both the header and frame body, but not FCS). This event is + * also used to indicate if the authentication attempt timed out. In that + * case the %NL80211_ATTR_FRAME attribute is replaced with a + * %NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which + * pending authentication timed out). + * @NL80211_CMD_ASSOCIATE: association request and notification; like + * NL80211_CMD_AUTHENTICATE but for Association and Reassociation + * (similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request, + * MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives). + * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like + * NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to + * MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication + * primitives). + * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like + * NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to + * MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives). + * + * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael + * MIC (part of TKIP) failure; sent on the "mlme" multicast group; the + * event includes %NL80211_ATTR_MAC to describe the source MAC address of + * the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key + * type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and + * %NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this + * event matches with MLME-MICHAELMICFAILURE.indication() primitive + * + * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a + * FREQ attribute (for the initial frequency if no peer can be found) + * and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those + * should be fixed rather than automatically determined. Can only be + * executed on a network interface that is UP, and fixed BSSID/FREQ + * may be rejected. Another optional parameter is the beacon interval, + * given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not + * given defaults to 100 TU (102.4ms). + * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is + * determined by the network interface. + * + * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute + * to identify the device, and the TESTDATA blob attribute to pass through + * to the driver. + * + * @NL80211_CMD_CONNECT: connection request and notification; this command + * requests to connect to a specified network but without separating + * auth and assoc steps. For this, you need to specify the SSID in a + * %NL80211_ATTR_SSID attribute, and can optionally specify the association + * IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_MAC, + * %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT, + * %NL80211_ATTR_CONTROL_PORT_ETHERTYPE and + * %NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT. + * It is also sent as an event, with the BSSID and response IEs when the + * connection is established or failed to be established. This can be + * determined by the STATUS_CODE attribute. + * @NL80211_CMD_ROAM: request that the card roam (currently not implemented), + * sent as an event when the card/driver roamed by itself. + * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify + * userspace that a connection was dropped by the AP or due to other + * reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and + * %NL80211_ATTR_REASON_CODE attributes are used. + * + * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices + * associated with this wiphy must be down and will follow. + * + * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified + * channel for the specified amount of time. This can be used to do + * off-channel operations like transmit a Public Action frame and wait for + * a response while being associated to an AP on another channel. + * %NL80211_ATTR_IFINDEX is used to specify which interface (and thus + * radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the + * frequency for the operation and %NL80211_ATTR_WIPHY_CHANNEL_TYPE may be + * optionally used to specify additional channel parameters. + * %NL80211_ATTR_DURATION is used to specify the duration in milliseconds + * to remain on the channel. This command is also used as an event to + * notify when the requested duration starts (it may take a while for the + * driver to schedule this time due to other concurrent needs for the + * radio). + * When called, this operation returns a cookie (%NL80211_ATTR_COOKIE) + * that will be included with any events pertaining to this request; + * the cookie is also used to cancel the request. + * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a + * pending remain-on-channel duration if the desired operation has been + * completed prior to expiration of the originally requested duration. + * %NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the + * radio. The %NL80211_ATTR_COOKIE attribute must be given as well to + * uniquely identify the request. + * This command is also used as an event to notify when a requested + * remain-on-channel duration has expired. + * + * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX + * rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface + * and @NL80211_ATTR_TX_RATES the set of allowed rates. + * + * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames + * (via @NL80211_CMD_FRAME) for processing in userspace. This command + * requires an interface index, a frame type attribute (optional for + * backward compatibility reasons, if not given assumes action frames) + * and a match attribute containing the first few bytes of the frame + * that should match, e.g. a single byte for only a category match or + * four bytes for vendor frames including the OUI. The registration + * cannot be dropped, but is removed automatically when the netlink + * socket is closed. Multiple registrations can be made. + * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for + * backward compatibility + * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This + * command is used both as a request to transmit a management frame and + * as an event indicating reception of a frame that was not processed in + * kernel code, but is for us (i.e., which may need to be processed in a + * user space application). %NL80211_ATTR_FRAME is used to specify the + * frame contents (including header). %NL80211_ATTR_WIPHY_FREQ (and + * optionally %NL80211_ATTR_WIPHY_CHANNEL_TYPE) is used to indicate on + * which channel the frame is to be transmitted or was received. If this + * channel is not the current channel (remain-on-channel or the + * operational channel) the device will switch to the given channel and + * transmit the frame, optionally waiting for a response for the time + * specified using %NL80211_ATTR_DURATION. When called, this operation + * returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the + * TX status event pertaining to the TX request. + * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this + * command may be used with the corresponding cookie to cancel the wait + * time if it is known that it is no longer necessary. + * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility. + * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame + * transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies + * the TX command and %NL80211_ATTR_FRAME includes the contents of the + * frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged + * the frame. + * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for + * backward compatibility. + * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command + * is used to configure connection quality monitoring notification trigger + * levels. + * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This + * command is used as an event to indicate the that a trigger level was + * reached. + * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ + * and %NL80211_ATTR_WIPHY_CHANNEL_TYPE) the given interface (identifed + * by %NL80211_ATTR_IFINDEX) shall operate on. + * In case multiple channels are supported by the device, the mechanism + * with which it switches channels is implementation-defined. + * When a monitor interface is given, it can only switch channel while + * no other interfaces are operating to avoid disturbing the operation + * of any other interfaces, and other interfaces will again take + * precedence when they are used. + * + * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface. + * + * @NL80211_CMD_JOIN_MESH: Join a mesh.
