2012-02-21mac80211: Fix a warning on changing to monitor mode from STAMohammed Shafi Shajakhan
nothing needs to be done for monitor/AP_VLAN mode on calling ieee80211_bss_info_change_notify -> drv_bss_info_changed with the change flag 'BSS_CHANGED_IDLE'. 'wl1271' seems to use BSS_CHANGED_IDLE only for STA and IBSS mode. further the non-idle state of the monitor mode is taken care by the 'count' variable which counts non-idle interfaces. ieee80211_idle_off(local, "in use") will be called. this fixes the following WARNING when we have initially STA mode (network manager running) and not associated, and change it to monitor mode with network manager disabled and bringing up the monitor mode. this changes the idle state from 'true' (STA unassociated) to 'false' (MONITOR mode) exposed by the commit 405385f8ce7a2ed8f82e216d88b5282142e1288b "mac80211: set bss_conf.idle when vif is connected" WARNING: net/mac80211/main.c:212 ieee80211_bss_info_change_notify+0x1cf/0x330 [mac80211]() Hardware name: 64756D6 Pid: 3835, comm: ifconfig Tainted: G O 3.3.0-rc3-wl #9 Call Trace: [<c0133b02>] warn_slowpath_common+0x72/0xa0 [<fc8e8c3f>] ? ieee80211_bss_info_change_notify+0x1cf/0x330 [mac80211] [<fc8e8c3f>] ? ieee80211_bss_info_change_notify+0x1cf/0x330 [mac80211] [<c0133b52>] warn_slowpath_null+0x22/0x30 [<fc8e8c3f>] ieee80211_bss_info_change_notify+0x1cf/0x330 [mac80211] [<fc8f9de3>] __ieee80211_recalc_idle+0x113/0x430 [mac80211] [<fc8fabc6>] ieee80211_do_open+0x156/0x7e0 [mac80211] [<fc8f8a25>] ? ieee80211_check_concurrent_iface+0x25/0x180 [mac80211] [<c015dd9f>] ? raw_notifier_call_chain+0x1f/0x30 [<fc8fb290>] ieee80211_open+0x40/0x80 [mac80211] [<c05894f6>] __dev_open+0x96/0xe0 [<c068fba5>] ? _raw_spin_unlock_bh+0x35/0x40 [<c05881d9>] __dev_change_flags+0x109/0x170 [<c0589423>] dev_change_flags+0x23/0x60 [<c05f3770>] devinet_ioctl+0x6a0/0x770 ieee80211 phy0: device no longer idle - in use Cc: Eliad Peller <eliad@wizery.com> Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: John W.

2012-02-21mac80211: zero initialize count field in ieee80211_tx_rateMohammed Shafi Shajakhan
rate control algorithms concludes the rate as invalid with rate[i].idx < -1 , while they do also check for rate[i].count is non-zero. it would be safer to zero initialize the 'count' field. recently we had a ath9k rate control crash where the ath9k rate control in ath_tx_status assumed to check only for rate[i].count being non-zero in one instance and ended up in using invalid rate index for 'connection monitoring NULL func frames' which eventually lead to the crash. thanks to Pavel Roskin for fixing it and finding the root cause. https://bugzilla.redhat.com/show_bug.cgi?id=768639 Cc: stable@vger.kernel.org Cc: Pavel Roskin <proski@gnu.org> Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: John W.

2012-02-21iwlwifi: fix key removalJohannes Berg
When trying to remove a key, we always send key flags just setting the key type, not including the multicast flag and the key ID. As a result, whenever any key was removed, the unicast key 0 would be removed, causing a complete connection loss after the second rekey (the first doesn't cause a key removal). Fix the key removal code to include the key ID and multicast flag, thus removing the correct key.

The 'rt2x00lib_probe_dev' function tries to allocate the workqueue. If the allocation fails, 'rt2x00_lib_remove_dev' is called on the error path. Because 'rt2x00dev->workqueue' is NULL in this case, the 'destroy_workqueue' call will cause a NULL pointer dereference.

2012-02-21percpu: use raw_local_irq_* in _this_cpu opMing Lei
It doesn't make sense to trace irq off or do irq flags lock proving inside 'this_cpu' operations, so replace local_irq_* with raw_local_irq_* in 'this_cpu' op. Also the patch fixes onelockdep warning[1] by the replacement, see below: In commit: 933393f58fef9963eac61db8093689544e29a600(percpu: Remove irqsafe_cpu_xxx variants), local_irq_save/restore(flags) are added inside this_cpu_inc operation, so that trace_hardirqs_off_caller will be called by trace_hardirqs_on_caller directly because __debug_atomic_inc is implemented as this_cpu_inc, which may trigger the lockdep warning[1], for example in the below ARM scenary: kernel_thread_helper /*irq disabled*/ ->trace_hardirqs_on_caller /*hardirqs_enabled was set*/ ->trace_hardirqs_off_caller /*hardirqs_enabled cleared*/ __this_cpu_add(redundant_hardirqs_on) ->trace_hardirqs_off_caller /*irq disabled, so call here*/ The 'unannotated irqs-on' warning will be triggered somewhere because irq is just enabled after the irq trace in kernel_thread_helper.

2012-02-21xfs: make inode quota check more generalMitsuo Hayasaka
The xfs checks quota when reserving disk blocks and inodes. In the block reservation, it checks if the total number of blocks including current usage and new reservation exceed quota. In the inode reservation, it checks using the total number of inodes including only current usage without new reservation. However, this inode quota check works well since the caller of xfs_trans_dquot() always sets the argument of the number of new inode reservation to 1 or 0 and inode is reserved one by one in current xfs. To make it more general, this patch changes it to the same way as the block quota check.

2012-02-21netfilter: ctnetlink: fix soft lockup when netlink adds new entriesJozsef Kadlecsik
Marcell Zambo and Janos Farago noticed and reported that when new conntrack entries are added via netlink and the conntrack table gets full, soft lockup happens. This is because the nf_conntrack_lock is held while nf_conntrack_alloc is called, which is in turn wants to lock nf_conntrack_lock while evicting entries from the full table. The patch fixes the soft lockup with limiting the holding of the nf_conntrack_lock to the minimum, where it's absolutely required.

2012-02-21netfilter: ebtables: fix alignment problem in ppcJoerg Willmann
ebt_among extension of ebtables uses __alignof__(_xt_align) while the corresponding kernel module uses __alignof__(ebt_replace) to determine the alignment in EBT_ALIGN(). These are the results of these values on different platforms: x86 x86_64 ppc __alignof__(_xt_align) 4 8 8 __alignof__(ebt_replace) 4 8 4 ebtables fails to add rules which use the among extension. I'm using kernel 2.6.33 and ebtables 2.0.10-4 According to Bart De Schuymer, userspace alignment was changed to _xt_align to fix an alignment issue on a userspace32-kernel64 system (he thinks it was for an ARM device). So userspace must be right. The kernel alignment macro needs to change so it also uses _xt_align instead of ebt_replace. The userspace changes date back from June 29, 2009.

2012-02-21ARM: 7336/1: smp_twd: Don't register CPUFREQ notifiers if local timers are ↵Santosh Shilimkar
not initialised Current ARM local timer code registers CPUFREQ notifiers even in case the twd_timer_setup() isn't called. That seems to be wrong and would eventually lead to kernel crash on the CPU frequency transitions on the SOCs where the local timer doesn't exist or broken because of hardware BUG. Fix it by testing twd_evt and *__this_cpu_ptr(twd_evt). The issue was observed with v3.3-rc3 and building an OMAP2+ kernel on OMAP3 SOC which doesn't have TWD. Below is the dump for reference : Unable to handle kernel paging request at virtual address 007e900 pgd = cdc20000 [007e9000] *pgd=00000000 Internal error: Oops: 5 [#1] SMP Modules linked in: CPU: 0 Not tainted (3.3.0-rc3-pm+debug+initramfs #9) PC is at twd_update_frequency+0x34/0x48 LR is at twd_update_frequency+0x10/0x48 pc : [<c001382c>] lr : [<c0013808>] psr: 60000093 sp : ce311dd8 ip : 00000000 fp : 00000000 r10: 00000000 r9 : 00000001 r8 : ce310000 r7 : c0440458 r6 : c00137f8 r5 : 00000000 r4 : c0947a74 r3 : 00000000 r2 : 007e9000 r1 : 00000000 r0 : 00000000 Flags: nZCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment usr Control: 10c5387d Table: 8dc20019 DAC: 00000015 Process sh (pid: 599, stack limit = 0xce3102f8) Stack: (0xce311dd8 to 0xce312000) 1dc0: 6000c 1de0: 00000001 00000002 00000000 00000000 00000000 00000000 00000 1e00: ffffffff c093d8f0 00000000 ce311ebc 00000001 00000001 ce310 1e20: c001386c c0437c4c c0e95b60 c0e95ba8 00000001 c0e95bf8 ffff4 1e40: 00000000 00000000 c005ef74 ce310000 c0435cf0 ce311ebc 00000 1e60: ce352b40 0007a120 c08d5108 c08ba040 c08ba040 c005f030 00000 1e80: c08bc554 c032fe2c 0007a120 c08d4b64 ce352b40 c08d8618 ffff8 1ea0: c08ba040 c033364c ce311ecc c0433b50 00000002 ffffffea c0330 1ec0: 0007a120 0007a120 22222201 00000000 22222222 00000000 ce357 1ee0: ce3d6000 cdc2aed8 ce352ba0 c0470164 00000002 c032f47c 00034 1f00: c0331cac ce352b40 00000007 c032f6d0 ce352bbc 0003d090 c0930 1f20: c093d8bc c03306a4 00000007 ce311f80 00000007 cdc2aec0 ce358 1f40: ce8d20c0 00000007 b6fe5000 ce311f80 00000007 ce310000 0000c 1f60: c000de74 ce987400 ce8d20c0 b6fe5000 00000000 00000000 0000c 1f80: 00000000 00000000 001fbac8 00000000 00000007 001fbac8 00004 1fa0: c000df04 c000dd60 00000007 001fbac8 00000001 b6fe5000 00000 1fc0: 00000007 001fbac8 00000007 00000004 b6fe5000 00000000 00202 1fe0: 00000000 beb565f8 00101ffc 00008e8c 60000010 00000001 00000 [<c001382c>] (twd_update_frequency+0x34/0x48) from [<c008ac4c>] ) [<c008ac4c>] (smp_call_function_single+0x17c/0x1c8) from [<c0013) [<c0013890>] (twd_cpufreq_transition+0x24/0x30) from [<c0437c4c>) [<c0437c4c>] (notifier_call_chain+0x44/0x84) from [<c005efe4>] () [<c005efe4>] (__srcu_notifier_call_chain+0x70/0xa4) from [<c005f) [<c005f030>] (srcu_notifier_call_chain+0x18/0x20) from [<c032fe2) [<c032fe2c>] (cpufreq_notify_transition+0xc8/0x1b0) from [<c0333) [<c033364c>] (omap_target+0x1b4/0x28c) from [<c032f47c>] (__cpuf) [<c032f47c>] (__cpufreq_driver_target+0x50/0x64) from [<c0331d24) [<c0331d24>] (cpufreq_set+0x78/0x98) from [<c032f6d0>] (store_sc) [<c032f6d0>] (store_scaling_setspeed+0x5c/0x74) from [<c03306a4>) [<c03306a4>] (store+0x58/0x74) from [<c014d868>] (sysfs_write_fi) [<c014d868>] (sysfs_write_file+0x80/0xb4) from [<c00f2c2c>] (vfs) [<c00f2c2c>] (vfs_write+0xa8/0x138) from [<c00f2e9c>] (sys_write) [<c00f2e9c>] (sys_write+0x40/0x6c) from [<c000dd60>] (ret_fast_s) Code: e594300c e792210c e1a01000 e5840004 (e7930002) ---[ end trace 5da3b5167c1ecdda ]--- Reported-by: Kevin Hilman <khilman@ti.com> Acked-by: Marc Zyngier <marc.zyngier@arm.com> Tested-by: Kevin Hilman <khilman@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-20i387: export 'fpu_owner_task' per-cpu variableLinus Torvalds
(And define it properly for x86-32, which had its 'current_task' declaration in separate from x86-64) Bitten by my dislike for modules on the machines I use, and the fact that apparently nobody else actually wanted to test the patches I sent out. Snif. Nobody else cares. Anyway, we probably should uninline the 'kernel_fpu_begin()' function that is what modules actually use and that references this, but this is the minimal fix for now.

2012-02-20x86: Specify a size for the cmp in the NMI handlerSteven Rostedt
Linus noticed that the cmp used to check if the code segment is __KERNEL_CS or not did not specify a size. Perhaps it does not matter as H. Peter Anvin noted that user space can not set the bottom two bits of the %cs register. But it's best not to let the assembly choose and change things between different versions of gas, but instead just pick the size. Four bytes are used to compare the saved code segment against __KERNEL_CS. Perhaps this might mess up Xen, but we can fix that when the time comes. Also I noticed that there was another non-specified cmp that checks the special stack variable if it is 1 or 0. This too probably doesn't matter what cmp is used, but this patch uses cmpl just to make it non ambiguous.

2012-02-20use FW 7.2.16Dmitry Kravkov
The patch integrates FW 7.2.16 HSI and implements driver part of GRO flow. FW 7.2.16 adds the ability to aggregate packets for GRO (and not just LRO) and also fixes some bugs. 1. Added new aggregation mode: GRO. In this mode packets are aggregated such that the original packets can be reconstructed by the OS. 2. 57712 HW bug workaround - initialized all CAM TM registers to 0x32. 3. Adding the FCoE statistics structures to the BNX2X HSI. 4. Wrong configuration of TX HW input buffer size may cause theoretical performance effect. Performed configuration fix. 5. FCOE - Arrival of packets beyond task IO size can lead to crash. Fix firmware data-in flow. 6. iSCSI - In rare cases of on-chip termination the graceful termination timer hangs, and the termination doesn't complete. Firmware fix to MSL timer tolerance. 7. iSCSI - Chip hangs when target sends FIN out-of-order or with isles open at the initiator side. Firmware implementation corrected to drop FIN received out-of-order or with isles still open. 8. iSCSI - Chip hangs when in case of retransmission not aligned to 4-bytes from the beginning of iSCSI PDU. Firmware implementation corrected to support arbitrary aligned retransmissions. 9. iSCSI - Arrival of target-initiated NOP-IN during intense ISCSI traffic might lead to crash. Firmware fix to relevant flow. Signed-off-by: Dmitry Kravkov <dmitry@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
