2010-03-29ring-buffer: Add missing unlockJulia Lawall
In some error handling cases the lock is not unlocked. The return is converted to a goto, to share the unlock at the end of the function. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ expression E1; identifier f; @@ f (...) { <+... * spin_lock_irq (E1,...); ... when != E1 * return ...; ...+> } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> LKML-Reference: <Pine.LNX.4.64.1003291736440.21896@ask.diku.dk> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

2010-03-29x86: Make sure free_init_pages() frees pages on page boundaryYinghai Lu
When CONFIG_NO_BOOTMEM=y, it could use memory more effiently, or in a more compact fashion. Example: Allocated new RAMDISK: 00ec2000 - 0248ce57 Move RAMDISK from 000000002ea04000 - 000000002ffcee56 to 00ec2000 - 0248ce56 The new RAMDISK's end is not page aligned. Last page could be shared with other users. When free_init_pages are called for initrd or .init, the page could be freed and we could corrupt other data. code segment in free_init_pages(): | for (; addr < end; addr += PAGE_SIZE) { | ClearPageReserved(virt_to_page(addr)); | init_page_count(virt_to_page(addr)); | memset((void *)(addr & ~(PAGE_SIZE-1)), | POISON_FREE_INITMEM, PAGE_SIZE); | free_page(addr); | totalram_pages++; | } last half page could be used as one whole free page. So page align the boundaries. -v2: make the original initramdisk to be aligned, according to Johannes, otherwise we have the chance to lose one page. we still need to keep initrd_end not aligned, otherwise it could confuse decompressor. -v3: change to WARN_ON instead, suggested by Johannes. -v4: use PAGE_ALIGN, suggested by Johannes. We may fix that macro name later to PAGE_ALIGN_UP, and PAGE_ALIGN_DOWN Add comments about assuming ramdisk start is aligned in relocate_initrd(), change to re get ramdisk_image instead of save it to make diff smaller. Add warning for wrong range, suggested by Johannes. -v6: remove one WARN() We need to align beginning in free_init_pages() do not copy more than ramdisk_size, noticed by Johannes Reported-by: Stanislaw Gruszka <sgruszka@redhat.com> Tested-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Yinghai Lu <yinghai@kernel.org> Acked-by: Johannes Weiner <hannes@cmpxchg.org> Cc: David Miller <davem@davemloft.net> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> LKML-Reference: <1269830604-26214-3-git-send-email-yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2010-03-29ARM: 5965/1: Fix soft lockup in at91 udc driverHarro Haan
Fix a potential soft lockup in the AT91 UDC driver by ensuring that the UDC clock is enabled inside the interrupt handler. If the UDC clock is not enabled then the UDC registers cannot be written to and the interrupt cannot be cleared or masked. Note that this patch (and other parts of the existing AT91 UDC driver) is potentially racy for preempt-rt kernels, but is okay for mainline.

2010-03-29ARM: 6005/1: arm: kprobes: fix register corruption with jprobesMika Westerberg
Current implementation of jprobes allocates empty pt_regs from the stack which is then passed to kprobe_handler() and eventually to singlestep(). Now when instruction being simulated is STMFD (like in normal function prologues without CONFIG_FRAME_POINTER), stores using SP actually write over top of the fabricated pt_regs structure. This can be reproduced for example by using LKDTM module: # modprobe lkdtm # mount -t debugfs none /sys/kernel/debug # echo PANIC > /sys/kernel/debug/provoke-crash/INT_HW_IRQ_EN after this, it fails with corrupted registers (before the requested crash would occur): lkdtm: Crash point INT_HW_IRQ_EN of type PANIC hit, trigger in 9 rounds lkdtm: Crash point INT_HW_IRQ_EN of type PANIC hit, trigger in 8 rounds Internal error: Oops - undefined instruction: 0 [#1] last sysfs file: /sys/devices/platform/serial8250.0/sleep_timeout Modules linked in: lkdtm CPU: 0 Not tainted (2.6.34-rc2 #69) PC is at irq_desc+0x1638/0xeeb0 LR is at 0x25 pc : [<c050b428>] lr : [<00000025>] psr: c80a0013 sp : ce94bd60 ip : c050b3e8 fp : a0000013 r10: c0aa453c r9 : cf5d4000 r8 : ce9a1822 r7 : c050b424 r6 : 00000025 r5 : c039d8f8 r4 : c050b3e8 r3 : 00000001 r2 : cf4d0440 r1 : c039d8f8 r0 : 00000020 Flags: NZcv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user Control: 10c5387d Table: 8e804019 DAC: 00000015 Process sh (pid: 496, stack limit = 0xce94a2e8) Stack: (0xce94bd60 to 0xce94c000) [...] Code: 000002cd 00000000 00000000 00000001 (dead4ead) ---[ end trace 2b46d5f2b682f370 ]--- Kernel panic - not syncing: Fatal exception in interrupt This patch allocates enough space (2 * sizeof(struct pt_regs)) from the stack to prevent such corruption.

2010-03-29ALSA: hda - Fix ADC/MUX assignment of ALC269 codecTakashi Iwai
ALC269 codec has a few different variants, and each of them may have different ADC and MUX widgets. For example, one model has ADC 0x08 with MUX 0x23 while others has ADC 0x09 or ADC 0x07 with MUX 022 or 0x24. The difference of ADC appears usually as the capability of the digital mic pin (0x12), and the current driver sometimes misses the internal mic pin due to the mismatching ADC. This patch adds a bit more clever way to find the matching ADC instead of the static list. Now the driver checks all active input pins and fills only the ADC/MUX's that contain all of them.

2010-03-27r8169: fix broken register writesFrancois Romieu
This is quite similar to b39fe41f481d20c201012e4483e76c203802dda7 though said registers are not even documented as 64-bit registers - as opposed to the initial TxDescStartAddress ones - but as single bytes which must be combined into 32 bits at the MMIO read/write level before being merged into a 64 bit logical entity. Credits go to Ben Hutchings <ben@decadent.org.uk> for the MAR registers (aka "multicast is broken for ages on ARM) and to Timo Teräs <timo.teras@iki.fi> for the MAC registers.

2010-03-27bonding: fix broken multicast with round-robin modeAndy Gospodarek
Round-robin (mode 0) does nothing to ensure that any multicast traffic originally destined for the host will continue to arrive at the host when the link that sent the IGMP join or membership report goes down. One of the benefits of absolute round-robin transmit. Keeping track of subscribed multicast groups for each slave did not seem like a good use of resources, so I decided to simply send on the curr_active slave of the bond (typically the first enslaved device that is up). This makes failover management simple as IGMP membership reports only need to be sent when the curr_active_slave changes. I tested this patch and it appears to work as expected.

2010-03-27[SCSI] qla1280: retain firmware for error recoveryMichael Reed
The qla1280 driver acquires its firmware via udev. During boot the firmware is located in the initrd. If, after root is mounted, the adapter needs to reload firmware (host reset), the firmware load may fail if the root device is on the adapter being reset. This patch modifies qla1280 to retain the firmware loaded via the initial request_firmware() for use during error recovery.

2010-03-27[SCSI] attirbute_container: Initialize sysfs attributes with sysfs_attr_initJames Bottomley
All of the SCSI transport classes are suddenly spitting lockdep warnings. According to Eric Biderman this is because lockdep needs static initialisers and the attribute container way of doing things end up with dynamic sysfs attributes. Fix this by calling sysfs_attr_init which sets the lockdep key correctly. Tested-by: Christof Schmitt <christof.schmitt@de.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
