2008-08-29mac80211/cfg80211: HT capabilities for NEW_STAJouni Malinen
Allow userspace (e.g., hostapd) to set HT capabilities for associated STAs. This is based on a patch from Zhu Yi <yi.zhu@intel.com> (only the NL80211_ATTR_HT_CAPABILITY for NEW_STA part is included here).

2008-08-29ssb: Clean up extraction of MAC addresses from SPROMLarry Finger
Only rev 1 and 2 ssb SPROMs have fields named et0mac and et1mac; however, all of the extraction routines extract pseudo data for these fields from regions that are all 1's resulting in a hardware address of FF:FF:FF:FF:FF:FF. This patch forces such a fill at the beginning of the data extraction process, and only does the formal extraction if the SPROM rev is 1 or 2.

2008-08-29ssb: Update for Rev. 5 SPROMLarry Finger
Although a revision 5 SPROM has not been seen in the wild, the open-source portion of the MIPS driver 4.150.10.5 describes its layout, which is mostly inherited from revision 4. This patch implements the differences. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Acked-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-08-29mac80211/cfg80211: Add BSS configuration options for AP modeJouni Malinen
This change adds a new cfg80211 command, NL80211_CMD_SET_BSS, to allow AP mode BSS parameters to be changed from user space (e.g., hostapd). The drivers using mac80211 are expected to be modified with separate changes to use the new BSS info parameter for short slot time in the bss_info_changed() handler.

2008-08-22rfkill: introduce RFKILL_STATE_MAXHenrique de Moraes Holschuh
While it is interesting to not add last-enum-markers because it allows gcc to warn us of switch() statements missing a valid state, we really should be handling memory corruption on a rfkill state with default clauses, anyway. So add RFKILL_STATE_MAX and use it where applicable. It makes for safer code in the long run.

2008-08-22rfkill: add __must_check annotationsHenrique de Moraes Holschuh
rfkill is not a small, mere detail in wireless support. Once it starts supporting rfkill and users start counting on that support, a wireless device is at risk of operating in dangerous conditions should rfkill support fail to properly activate. Therefore, add the required __must_check annotations on some key functions of the rfkill API, for which the wireless drivers absolutely MUST handle the failure mode safely in order to avoid a potentially dangerous situation where the wireless transmitter is left enabled when the user don't want it to.

2008-08-22rfkill: add default global states (v2)Henrique de Moraes Holschuh
Add a second set of global states, "rfkill_default_states", to track the state that will be used when the first rfkill class of a given type is registered, and also to save "undo" information when rfkill_epo is called. Add a new exported function, rfkill_set_default(), which can be used by platform drivers to restore radio state saved by the platform across reboots or shutdown. Also, fix rfkill_epo to properly update rfkill_states, but still preserve a copy of the state so that we can undo the effect of rfkill_epo later if we want to. Add rfkill_restore_states() to restore rfkill_states from the copy. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-08-21pkt_sched: Fix qdisc_watchdog() vs. dev_deactivate() raceJarek Poplawski
dev_deactivate() can skip rescheduling of a qdisc by qdisc_watchdog() or other timer calling netif_schedule() after dev_queue_deactivate(). We prevent this checking aliveness before scheduling the timer. Since during deactivation the root qdisc is available only as qdisc_sleeping additional accessor qdisc_root_sleeping() is created.

2008-08-20mm: dirty page tracking race fixNick Piggin
There is a race with dirty page accounting where a page may not properly be accounted for. clear_page_dirty_for_io() calls page_mkclean; then TestClearPageDirty. page_mkclean walks the rmaps for that page, and for each one it cleans and write protects the pte if it was dirty. It uses page_check_address to find the pte. That function has a shortcut to avoid the ptl if the pte is not present. Unfortunately, the pte can be switched to not-present then back to present by other code while holding the page table lock -- this should not be a signal for page_mkclean to ignore that pte, because it may be dirty. For example, powerpc64's set_pte_at will clear a previously present pte before setting it to the desired value. There may also be other code in core mm or in arch which do similar things. The consequence of the bug is loss of data integrity due to msync, and loss of dirty page accounting accuracy. XIP's __xip_unmap could easily also be unreliable (depending on the exact XIP locking scheme), which can lead to data corruption. Fix this by having an option to always take ptl to check the pte in page_check_address. It's possible to retain this optimization for page_referenced and try_to_unmap.

2008-08-20fix setpriority(PRIO_PGRP) thread iterator breakageKen Chen
When user calls sys_setpriority(PRIO_PGRP ...) on a NPTL style multi-LWP process, only the task leader of the process is affected, all other sibling LWP threads didn't receive the setting. The problem was that the iterator used in sys_setpriority() only iteartes over one task for each process, ignoring all other sibling thread.

2008-08-20Reduce brokenness of CRIS headers_installDavid Woodhouse
I won't say 'fix', because they still look broken, although this will at least allow 'make ARCH=CRIS headers_install' to _complete_. For headers which are exported, we should probably choose between asm/arch-v10 and asm/arch-v32 by something that GCC defines -- we can't rely on a generated symlink. And we certainly can't export an arch/ directory which doesn't even exist. And the only thing that we seem to include from the arch/ directory is <asm/arch/ptrace.h> from <asm/ptrace.h> ... and that isn't exported in either arch-v10 or arch-v32 _anyway_.

2008-08-18x86, percpu: silence section mismatch warnings related to EARLY_PER_CPU ↵Marcin Slusarz
variables Quoting Mike Travis in "x86: cleanup early per cpu variables/accesses v4" (23ca4bba3e20c6c3cb11c1bb0ab4770b724d39ac): The DEFINE macro defines the per_cpu variable as well as the early map and pointer. It also initializes the per_cpu variable and map elements to "_initvalue". The early_* macros provide access to the initial map (usually setup during system init) and the early pointer. This pointer is initialized to point to the early map but is then NULL'ed when the actual per_cpu areas are setup. After that the per_cpu variable is the correct access to the variable. As these variables are NULL'ed before __init sections are dropped (in setup_per_cpu_maps), they can be safely annotated as __ref. This change silences following section mismatch warnings: WARNING: vmlinux.o(.data+0x46c0): Section mismatch in reference from the variable x86_cpu_to_apicid_early_ptr to the variable .init.data:x86_cpu_to_apicid_early_map The variable x86_cpu_to_apicid_early_ptr references the variable __initdata x86_cpu_to_apicid_early_map If the reference is valid then annotate the variable with __init* (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, WARNING: vmlinux.o(.data+0x46c8): Section mismatch in reference from the variable x86_bios_cpu_apicid_early_ptr to the variable .init.data:x86_bios_cpu_apicid_early_map The variable x86_bios_cpu_apicid_early_ptr references the variable __initdata x86_bios_cpu_apicid_early_map If the reference is valid then annotate the variable with __init* (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, WARNING: vmlinux.o(.data+0x46d0): Section mismatch in reference from the variable x86_cpu_to_node_map_early_ptr to the variable .init.data:x86_cpu_to_node_map_early_map The variable x86_cpu_to_node_map_early_ptr references the variable __initdata x86_cpu_to_node_map_early_map If the reference is valid then annotate the variable with __init* (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Cc: Mike Travis <travis@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-08-18x86: correct register constraints for 64-bit atomic operationsMathieu Desnoyers
x86_64 add/sub atomic ops does not seems to accept integer values bigger than 32 bits as immediates. Intel's add/sub documentation specifies they have to be passed as registers. The only operations in the x86-64 architecture which accept arbitrary 64-bit immediates is "movq" to any register; similarly, the only operation which accept arbitrary 64-bit displacement is "movabs" to or from al/ax/eax/rax. http://gcc.gnu.org/onlinedocs/gcc-4.3.0/gcc/Machine-Constraints.html states : e 32-bit signed integer constant, or a symbolic reference known to fit that range (for immediate operands in sign-extending x86-64 instructions). Z 32-bit unsigned integer constant, or a symbolic reference known to fit that range (for immediate operands in zero-extending x86-64 instructions). Since add/sub does sign extension, using the "e" constraint seems appropriate. It applies to 2.6.27-rc, 2.6.26, 2.6.25...

This new state lets dev_deactivate() mark a qdisc as having been deactivated. dev_queue_xmit() and ing_filter() check for this bit and do not try to process the qdisc if the bit is set. dev_deactivate() polls the qdisc after setting the bit, waiting for both __QDISC_STATE_RUNNING and __QDISC_STATE_SCHED to clear. This isn't perfect yet, but subsequent changesets will make it so. This part is just one piece of the puzzle. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-16Fix header export of videodev2.h, ivtv.h, ivtvfb.hDavid Woodhouse
The exported copy of videodev2.h contains this line: #define #include <sys/time.h> This is because for some reason it defines __user for itself -- despite the fact that we remove all instances of __user when exporting headers. _All_ pointers in userspace are user pointers. Fix it by removing the unnecessary '#define __user' from the file. The new headers ivtv.h and ivtvfb.h would have the same problem... if whoever put them there had actually remembered to add them to the Kbuild file while he was at it. Fix those too, and export them as was presumably intended. Note that includes of <linux/compiler.h> are also stripped by the header export process, so those don't need to be conditional.

2008-08-15net: skb_copy_datagram_from_iovec()Rusty Russell
There's an skb_copy_datagram_iovec() to copy out of a paged skb, but nothing the other way around (because we don't do that). We want to allocate big skbs in tun.c, so let's add the function. It's a carbon copy of skb_copy_datagram_iovec() with enough changes to be annoying. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-15tun: TUNGETIFF interface to query name and flagsMark McLoughlin
Add a TUNGETIFF interface so that userspace can query a tun/tap descriptor for its name and flags. This is needed because it is common for one app to create a tap interface, exec another app and pass it the file descriptor for the interface. Without TUNGETIFF the spawned app has no way of detecting wheter the interface has e.g. IFF_VNET_HDR set.
