NET: fix oops at bootime in sysctl code

2010-02-09T12:51:02+00:00

This fixes the boot time oops on the 2.6.32-stable tree. It is needed only in this tree due to the divergance from upstream. From: jamal Acked-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

powerpc: TIF_ABI_PENDING bit removal

2010-02-09T12:51:02+00:00

commit 94f28da8409c6059135e89ac64a0839993124155 upstream. Here are the powerpc bits to remove TIF_ABI_PENDING now that set_personality() is called at the appropriate place in exec. Signed-off-by: Andreas Schwab Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Greg Kroah-Hartman

ath9k: fix beacon slot/buffer leak

2010-02-09T12:51:01+00:00

commit 74401773f80b6d42f7a4c6994ca0cca883b03745 upstream. When cleaning up beacon buffers and slots, ath9k currently checks if sc->ah->opmode is set to a beacon related mode before cleaning up buffers. An unfortunate ordering of interface up/down commands can lead to sc->ah->opmode being set to monitor mode, while there are AP interfaces present on the same wiphy. Always cleaning up beacon buffers if present fixes this issue. Signed-off-by: Felix Fietkau Signed-off-by: John W. Linville Signed-off-by: Greg Kroah-Hartman

ath9k: fix eeprom INI values override for 2GHz-only cards

2010-02-09T12:51:01+00:00

commit aa8bc9ef18a2c5b2b97e1f36ee9604cf15743f96 upstream. Among other changes, this commit: commit 06d0f0663e11cab4ec5f2c143a118d71a12fbbe9 Author: Sujith Date: Thu Feb 12 10:06:45 2009 +0530 ath9k: Enable Fractional N mode changed the hw attach code to fix up initialization values only for dual band devices, however the commit message did not give a reason as to why this would be useful or necessary. According to tests by Jorge Boncompte, this breaks at least some 2GHz-only cards, so the code should be changed back to the unconditional INI fixup.

pktcdvd: removing device does not remove its sysfs dir

2010-02-09T12:51:01+00:00

commit ca0bf64d99f6e3f6e2fe2585e52a0ac57354beac upstream. This is the counterpart to cba767175becadc5c4016cceb7bfdd2c7fe722f4 ("pktcdvd: remove broken dev_t export of class devices"). Device is not registered using dev_t, so it should not be destroyed using device_destroy which looks up the device by dev_t. This will fail and adding the device again will fail with the "duplicate name" error. This is fixed using device_unregister instead of device_destroy.

uartlite: fix crash when using as console

2010-02-09T12:51:01+00:00

commit 03eac7bb882a75e6ee5705288f7ec36ad2e7d0d5 upstream. Move the ulite_console_setup to the .devinit section since it might be called on probe, which is in devinit. Fixes the crash below where the uartlite hw is probed after the .init section is freed from the kernel. uartlite: ttyUL0 at MMIO 0xc8000100 (irq = 30) is a uartlite BUG: unable to handle kernel NULL pointer dereference at (null) IP: [] ulite_console_setup+0x6f/0xa8 *pdpt = 0000000036fb0001 *pde = 0000000000000000 Oops: 0000 [#1] PREEMPT SMP last sysfs file: /sys/devices/pci0000:00/0000:00:1f.1/host0/uevent Modules linked in: puffin(+) serio_raw Pid: 151, comm: modprobe Not tainted (2.6.31.5-1.0.b1-b1 #1) POULSBO EIP: 0060:[] EFLAGS: 00010246 CPU: 0 EIP is at ulite_console_setup+0x6f/0xa8 EAX: c16ec824 EBX: c16ec824 ECX: c176719f EDX: 00000000 ESI: 00000000 EDI: c17b42c4 EBP: f6fd1cf0 ESP: f6fd1cd8 DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 Process modprobe (pid: 151, ti=f6fd0000 task=f6fa1020 task.ti=f6fd0000) Stack: c1031f51 00000000 00000000 00000246 c182237c f7742000 f6fd1d5c c11fd316 <0> c16ec85c f77420d4 0000001e 00000000 00000000 c1633e78 4f494d4d 63783020 <0> 30303038 00303031 f6fd1d3c c10e0786 f6fd1d48 00000000 f6fd1d48 00000000 Call Trace: [] ? register_console+0xf6/0x1fc [] ? uart_add_one_port+0x237/0x2bb [] ? sysfs_add_one+0x13/0xd3 [] ? sysfs_do_create_link+0xba/0xfc [] ? ulite_probe+0x198/0x1eb [] ? platform_drv_probe+0xc/0xe [] ? driver_probe_device+0x79/0x105 [] ? __device_attach+0x28/0x30 [] ? bus_for_each_drv+0x3d/0x67 [] ? device_attach+0x44/0x58 [] ? __device_attach+0x0/0x30 [] ? bus_probe_device+0x1f/0x34 [] ? device_add+0x385/0x4c0 [] ? _write_unlock+0x8/0x1f [] ? platform_device_add+0xd9/0x11c [] ? mfd_add_devices+0x165/0x1bc [] ? puffin_probe+0x2d0/0x390 [puffin] [] ? pci_match_device+0xa0/0xa7 [] ? local_pci_probe+0xe/0x10 [] ? pci_device_probe+0x43/0x66 [] ? driver_probe_device+0x79/0x105 [] ? __driver_attach+0x43/0x5f [] ? bus_for_each_dev+0x3d/0x67 [] ? driver_attach+0x14/0x16 [] ? __driver_attach+0x0/0x5f [] ? bus_add_driver+0xf9/0x220 [] ? driver_register+0x8b/0xeb [] ? __pci_register_driver+0x43/0x9f [] ? __blocking_notifier_call_chain+0x40/0x4c [] ? puffin_init+0x0/0x48 [puffin] [] ? puffin_init+0x17/0x48 [puffin] [] ? do_one_initcall+0x4c/0x131 [] ? sys_init_module+0xa7/0x1b7 [] ? syscall_call+0x7/0xb Code: 6e 74 00 00 00 92 33 00 00 18 00 0e 01 73 79 6e 63 65 2d 72 65 67 69 73 74 72 79 0c 00 49 32 00 00 14 00 09 01 61 6c 73 61 2d 69 <6e> 66 6f 00 00 00 42 37 00 00 10 00 07 01 6b 69 6c 6c 61 6c 6c EIP: [] ulite_console_setup+0x6f/0xa8 SS:ESP 0068:f6fd1cd8 CR2: 0000000000000000 Signed-off-by: Richard Röjfors Acked-by: Peter Korsgaard Cc: Alan Cox Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman

starfire: clean up properly if firmware loading fails

2010-02-09T12:51:00+00:00

commit c928febf4bc703ea542340e5a208e0445d998839 upstream. netdev_open() will return without cleaning up net device or hardware state if firmware loading fails. This results in a BUG() on a second attempt to bring the interface up, reported in , and probably has even worse effects if the driver is removed afterwards. Call netdev_close() to clean up on failure.

mx3fb: some debug and initialisation fixes

commit b3cb53721890879d7bde31f5f9eefd4edf41ab64 upstream. Fix the kernel oops when dev_dbg is called with mx3_fbi->txd == NULL Fix the late initialisation of mx3fb->backlight_level. If not, in the chain of function started by init_fb_chan(), in __blank() call sdc_set_brightness(mx3fb, mx3fb->backlight_level) that will shut down the CONTRAST PWM output.
