2011-11-09ah: Correctly pass error codes in ahash output callback.Nick Bowler
The AH4/6 ahash output callbacks pass nexthdr to xfrm_output_resume instead of the error code. This appears to be a copy+paste error from the input case, where nexthdr is expected. This causes the driver to continuously add AH headers to the datagram until either an allocation fails and the packet is dropped or the ahash driver hits a synchronous fallback and the resulting monstrosity is transmitted. Correct this issue by simply passing the error code unadulterated. Signed-off-by: Nick Bowler <nbowler@elliptictech.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-11-09Btrfs: rework error handling in btrfs_mount()Ilya Dryomov
Commits 6c41761f and 45ea6095 introduced the possibility of NULL pointer dereference on error paths, also we would leave all devices busy and leak fs_info with all sub-structures on error when trying to mount an already mounted fs to a different directory.

2011-11-09Btrfs: avoid null dereference and leaks when bailing from open_ctree()Ilya Dryomov
Fix bugs introduced by 6c41761f. Firstly, after failing to allocate any of the tree roots (first 'goto fail' in open_ctree()) we would dereference a NULL fs_info pointer in free_fs_info(). Secondly, after failures from init_srcu_struct(), setup_bdi() and new_inode() we would leak all earlier allocated roots: fs_info fields haven't been initialized yet so free_fs_info() is rendered useless. Fix this by initializing fs_info pointer and fs_info fields before any allocations happen. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

2011-11-09cfg80211: fix bug on regulatory core exit on access to last_requestLuis R. Rodriguez
Commit 4d9d88d1 by Scott James Remnant <keybuk@google.com> added the .uevent() callback for the regulatory device used during the platform device registration. The change was done to account for queuing up udev change requests through udevadm triggers. The change also meant that upon regulatory core exit we will now send a uevent() but the uevent() callback, reg_device_uevent(), also accessed last_request. Right before commiting device suicide we free'd last_request but never set it to NULL so platform_device_unregister() would lead to bogus kernel paging request. Fix this and also simply supress uevents right before we commit suicide as they are pointless. This fix is required for kernels >= v2.6.39 $ git describe --contains 4d9d88d1 v2.6.39-rc1~468^2~25^2^2~21 The impact of not having this present is that a bogus paging access may occur (only read) upon cfg80211 unload time. You may also get this BUG complaint below. Although Johannes could not reproduce the issue this fix is theoretically correct. mac80211_hwsim: unregister radios mac80211_hwsim: closing netlink BUG: unable to handle kernel paging request at ffff88001a06b5ab IP: [<ffffffffa030df9a>] reg_device_uevent+0x1a/0x50 [cfg80211] PGD 1836063 PUD 183a063 PMD 1ffcb067 PTE 1a06b160 Oops: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC CPU 0 Modules linked in: cfg80211(-) [last unloaded: mac80211] Pid: 2279, comm: rmmod Tainted: G W 3.1.0-wl+ #663 Bochs Bochs RIP: 0010:[<ffffffffa030df9a>] [<ffffffffa030df9a>] reg_device_uevent+0x1a/0x50 [cfg80211] RSP: 0000:ffff88001c5f9d58 EFLAGS: 00010286 RAX: 0000000000000000 RBX: ffff88001d2eda88 RCX: ffff88001c7468fc RDX: ffff88001a06b5a0 RSI: ffff88001c7467b0 RDI: ffff88001c7467b0 RBP: ffff88001c5f9d58 R08: 000000000000ffff R09: 000000000000ffff R10: 0000000000000000 R11: 0000000000000001 R12: ffff88001c7467b0 R13: ffff88001d2eda78 R14: ffffffff8164a840 R15: 0000000000000001 FS: 00007f8a91d8a6e0(0000) GS:ffff88001fc00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: ffff88001a06b5ab CR3: 000000001c62e000 CR4: 00000000000006f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process rmmod (pid: 2279, threadinfo ffff88001c5f8000, task ffff88000023c780) Stack: ffff88001c5f9d98 ffffffff812ff7e5 ffffffff8176ab3d ffff88001c7468c2 000000000000ffff ffff88001d2eda88 ffff88001c7467b0 ffff880000114820 ffff88001c5f9e38 ffffffff81241dc7 ffff88001c5f9db8 ffffffff81040189 Call Trace: [<ffffffff812ff7e5>] dev_uevent+0xc5/0x170 [<ffffffff81241dc7>] kobject_uevent_env+0x1f7/0x490 [<ffffffff81040189>] ? sub_preempt_count+0x29/0x60 [<ffffffff814cab1a>] ? _raw_spin_unlock_irqrestore+0x4a/0x90 [<ffffffff81305307>] ? devres_release_all+0x27/0x60 [<ffffffff8124206b>] kobject_uevent+0xb/0x10 [<ffffffff812fee27>] device_del+0x157/0x1b0 [<ffffffff8130377d>] platform_device_del+0x1d/0x90 [<ffffffff81303b76>] platform_device_unregister+0x16/0x30 [<ffffffffa030fffd>] regulatory_exit+0x5d/0x180 [cfg80211] [<ffffffffa032bec3>] cfg80211_exit+0x2b/0x45 [cfg80211] [<ffffffff8109a84c>] sys_delete_module+0x16c/0x220 [<ffffffff8108a23e>] ? trace_hardirqs_on_caller+0x7e/0x120 [<ffffffff814cba02>] system_call_fastpath+0x16/0x1b Code: <all your base are belong to me> RIP [<ffffffffa030df9a>] reg_device_uevent+0x1a/0x50 [cfg80211] RSP <ffff88001c5f9d58> CR2: ffff88001a06b5ab ---[ end trace 147c5099a411e8c0 ]--- Reported-by: Johannes Berg <johannes@sipsolutions.net> Cc: Scott James Remnant <keybuk@google.com> Cc: stable@vger.kernel.org Signed-off-by: Luis R.

2011-11-09arm/tegra: Don't create duplicate gpio and pinmux devicesStephen Warren
*_pinmux_init() register the GPIO and pinmux devices so that they're ready before any other device needs them. *_pinmux_init() are also called by board-dt.c in order to set up the GPIO and pinmux configurations. In this case, if we register the devices, they end up being probed once due to this registration, and a second time due to a device-tree node (or vice-versa). The second probe fails since the memory regions are already requested. Besides, we don't actually want the duplicated devices. To avoid this duplicate registration, modify *_pinmux_init() to check whether it's running on a DT machine. If not, register the pinmux devices. If so, don't register them. Finally, modify board-dt.c to call the *_pinmux_init() after all devices have been instantiated from device-tree. This allows the GPIO and pinmux devices to be instantiated and initialized before calling functions to configure the hardware. This has one disadvantage: The pinmux and GPIO initialization now happens after /all/ devices are instantiated, rather than after just gpio and pinmux but before anything else. So the correct HW configuration is not in place when e.g. the SD/MMC device is probed. Long-term, this should be solved by doing both: a) Initializing the HW state from DT nodes during GPIO and pinmux device probe. b) Using the deferred driver probe mechanism, so that drivers can defer their probe until after the gpio and pinmux drivers have probed. v2: s/int is_dt/bool is_dt/ v3: Use of_machine_is_compatible inside *_pinmux_init() rather than passing an explicit parameter into the function from outside.

2011-11-09[SCSI] Silencing 'killing requests for dead queue'Hannes Reinecke
When we tear down a device we try to flush all outstanding commands in scsi_free_queue(). However the check in scsi_request_fn() is imperfect as it only signals that we _might start_ aborting commands, not that we've actually aborted some. So move the printk inside the scsi_kill_request function, this will also give us a hint about which commands are aborted.

2011-11-09ALSA: intel8x0: improve virtual environment detectionKonstantin Ozerkov
Detection code improved by PCI SSID usage. VM optimization now enabled only for known devcices (skip host devices forwarded to VM by VT-d or same kind of technology). For debug/troubleshooting purposes optimization can be forced (on/off) by module parameter: "inside_vm" (boolean). Known devices (PCI SSID): 1af4:1100: Reserved for KVM devices. Note this is not yet implemented for KVM's ICH/AC'97 emulation. 1ab8:xxxx: Parallels ICH/AC'97 emulated sound.
