2013-09-30fs/binfmt_elf.c: prevent a coredump with a large vm_map_count from OopsingDan Aloni1-12/+18
A high setting of max_map_count, and a process core-dumping with a large enough vm_map_count could result in an NT_FILE note not being written, and the kernel crashing immediately later because it has assumed otherwise. Reproduction of the oops-causing bug described here: https://lkml.org/lkml/2013/8/30/50 Rge ussue originated in commit 2aa362c49c31 ("coredump: extend core dump note section to contain file names of mapped file") from Oct 4, 2012. This patch make that section optional in that case. fill_files_note() should signify the error, and also let the info struct in elf_core_dump() be zero-initialized so that we can check for the optionally written note.

This reverts commit cea27eb2a202 ("mm/memory-hotplug: fix lowmem count overflow when offline pages"). The fixed bug by commit cea27eb was fixed to another way by commit 3dcc0571cd64 ("mm: correctly update zone->managed_pages").

2013-09-30ipv6: Fix preferred_lft not updating in some casesPaul Marks1-37/+15
Consider the scenario where an IPv6 router is advertising a fixed preferred_lft of 1800 seconds, while the valid_lft begins at 3600 seconds and counts down in realtime. A client should reset its preferred_lft to 1800 every time the RA is received, but a bug is causing Linux to ignore the update. The core problem is here: if (prefered_lft != ifp->prefered_lft) { Note that ifp->prefered_lft is an offset, so it doesn't decrease over time. Thus, the comparison is always (1800 != 1800), which fails to trigger an update. The most direct solution would be to compute a "stored_prefered_lft", and use that value in the comparison. But I think that trying to filter out unnecessary updates here is a premature optimization. In order for the filter to apply, both of these would need to hold: - The advertised valid_lft and preferred_lft are both declining in real time. - No clock skew exists between the router & client. So in this patch, I've set "update_lft = 1" unconditionally, which allows the surrounding code to be greatly simplified.

Recent commit 8fd37a4 (PM / hibernate: Create memory bitmaps after freezing user space) broke the resume part of the user space driven hibernation (s2disk), because I forgot that the resume utility loaded the image into memory without freezing user space (it still freezes tasks after loading the image). This means that during user space driven resume we need to create the memory bitmaps at the "device open" time rather than at the "freeze tasks" time, so make that happen (that's a special case anyway, so it needs to be treated in a special way).

HWMOD removal for MMC is breaking edma_start as the events are being manually triggered due to unused channel list not being clear. The above issue is fixed by reading the "dmas" property from the DT node if it exists and clearing the bits in the unused channel list if the dma controller used by any device is EDMA. For this purpose we use the of_* helpers to parse the arguments in the dmas phandle list. Also introduced is a minor clean up of a checkpatch error in old code.

2013-09-30ARM: vexpress: tc2: fix hotplug/idle/kexec race on cluster power downLorenzo Pieralisi1-1/+10
On the TC2 testchip, when all CPUs in a cluster enter standbywfi and commit a power down request, the power controller will wait for standbywfil2 coming from L2 cache controller to shut the cluster down. By the time all CPUs in a cluster commit a power down request and enter wfi, the power controller cannot backtrack, or put it another way, a CPU must not be allowed to complete execution independently of the power controller, the only way for it to resume properly must be upon wake-up IRQ pending and subsequent reset triggered from the power controller. Current MCPM back-end for TC2 disables the GIC CPU IF only when power down is committed through the tc2_pm_suspend() method, that makes sense since a suspended CPU is still online and can receive interrupts whereas a hotplugged CPU, since it is offline, migrated all IRQs and shutdown the per-CPU peripherals, hence their PPIs. The flaw with this reasoning is the following. If all CPUs in a clusters are entering a power down state either through CPU idle or CPU hotplug, when the last man successfully completes the MCPM power down sequence (and executes wfi), power controller waits for L2 wfi signal to quiesce the cluster and shut it down. If, when all CPUs are sitting in wfi, an online CPU hotplugs back in one of the CPUs in the cluster being shutdown, that CPU receives an IPI that causes wfi to complete (since tc2_pm_down() method does not disable the GIC CPU IF in that case - CPU being hotplugged out, not idle) and the power controller will never see the stanbywfil2 signal coming from L2 that is required for shutdown to happen and the system deadlocks. Further to this issue, kexec hotplugs secondary CPUs out during kernel reload/restart. Because kexec may (deliberately) trash the old kernel text, it is not OK for CPUs to follow the MCPM soft reboot path, since instructions after the WFI may have been replaced by kexec. If tc2_pm_down() does not disable the GIC cpu interface, there is a race between CPU powerdown in the old kernel and the IPI from the new kernel that triggers secondary boot, particularly if the powerdown is slow (due to L2 cache cleaning for example). If the new kernel wins the race, the affected CPU(s) will not really be reset and may execute garbage after the WFI. The only solution to this problem consists in disabling the GIC CPU IF on a CPU committed to power down regardless of the power down entry method (CPU hotplug or CPU idle). This way, CPU wake-up is under power controller control, which prevents unexpected wfi exit caused by a pending IRQ. This patch moves the GIC CPU IF disable call in the TC2 MCPM implementation from the tc2_pm_suspend() method to the tc2_pm_down() method to fix the mentioned race condition(s).

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v3.12 Nothing too exciting here, all driver specific except for the fix from Liam for DPCM systems which have both front and back end DAIs which is not yet used by anything in mainline.

2013-09-30avr32: fix clockevents kernel warningGabor Juhos1-1/+8
Since commit 01426478df3a8791ff5c8b6b82d409e699cfaf38 (avr32: Use generic idle loop) the kernel throws the following warning on avr32: WARNING: at 900322e4 [verbose debug info unavailable] Modules linked in: CPU: 0 PID: 0 Comm: swapper Not tainted 3.12.0-rc2 #117 task: 901c3ecc ti: 901c0000 task.ti: 901c0000 PC is at cpu_idle_poll_ctrl+0x1c/0x38 LR is at comparator_mode+0x3e/0x40 pc : [<900322e4>] lr : [<90014882>] Not tainted sp : 901c1f74 r12: 00000000 r11: 901c74a0 r10: 901d2510 r9 : 00000001 r8 : 901db4de r7 : 901c74a0 r6 : 00000001 r5 : 00410020 r4 : 901db574 r3 : 00410024 r2 : 90206fe0 r1 : 00000000 r0 : 007f0000 Flags: qvnzc Mode bits: hjmde....G CPU Mode: Supervisor Call trace: [<90039ede>] clockevents_set_mode+0x16/0x2e [<90039f00>] clockevents_shutdown+0xa/0x1e [<9003a078>] clockevents_exchange_device+0x58/0x70 [<9003a78c>] tick_check_new_device+0x38/0x54 [<9003a1a2>] clockevents_register_device+0x32/0x90 [<900035c4>] time_init+0xa8/0x108 [<90000520>] start_kernel+0x128/0x23c When the 'avr32_comparator' clockevent device is registered, the clockevent core sets the mode of that clockevent device to CLOCK_EVT_MODE_SHUTDOWN. Due to this, the 'comparator_mode' function calls the 'cpu_idle_poll_ctrl' to disables idle poll. This results in the aforementioned warning because the polling is not enabled yet. Change the code to only disable idle poll if it is enabled by the same function to avoid the warning.
