2016-02-09workqueue: schedule WORK_CPU_UNBOUND work on wq_unbound_cpumask CPUsMike Galbraith1-2/+32
WORK_CPU_UNBOUND work items queued to a bound workqueue always run locally. This is a good thing normally, but not when the user has asked us to keep unbound work away from certain CPUs. Round robin these to wq_unbound_cpumask CPUs instead, as perturbation avoidance trumps performance. tj: Cosmetic and comment changes. WARN_ON_ONCE() dropped from empty (wq_unbound_cpumask AND cpu_online_mask). If we want that, it should be done when config changes.

2016-02-09Revert "workqueue: make sure delayed work run in local cpu"Tejun Heo1-4/+4
This reverts commit 874bbfe600a660cba9c776b3957b1ce393151b76. Workqueue used to implicity guarantee that work items queued without explicit CPU specified are put on the local CPU. Recent changes in timer broke the guarantee and led to vmstat breakage which was fixed by 176bed1de5bf ("vmstat: explicitly schedule per-cpu work on the CPU we need it to run on"). vmstat is the most likely to expose the issue and it's quite possible that there are other similar problems which are a lot more difficult to trigger. As a preventive measure, 874bbfe600a6 ("workqueue: make sure delayed work run in local cpu") was applied to restore the local CPU guarnatee. Unfortunately, the change exposed a bug in timer code which got fixed by 22b886dd1018 ("timers: Use proper base migration in add_timer_on()"). Due to code restructuring, the commit couldn't be backported beyond certain point and stable kernels which only had 874bbfe600a6 started crashing. The local CPU guarantee was accidental more than anything else and we want to get rid of it anyway. As, with the vmstat case fixed, 874bbfe600a6 is causing more problems than it's fixing, it has been decided to take the chance and officially break the guarantee by reverting the commit. A debug feature will be added to force foreign CPU assignment to expose cases relying on the guarantee and fixes for the individual cases will be backported to stable as necessary.

2016-02-09scripts: add "prune-kernel" script to clean up old kernel imagesJ. Bruce Fields1-0/+20
Long ago, Dave Jones complained about CONFIG_LOCALVERSION_AUTO: "I don't use the auto config, because I end up filling up /boot unless I go through and clean them out by hand every time I install a new one (which I do probably a dozen or so times a day). Is there some easy way to prune old builds I'm missing?" To which Bruce replied: "I run this by hand every now and then. I'm probably doing it all wrong" And if he is running it wrong, then so am I - because I've been using this script ever since. It is true that CONFIG_LOCALVERSION_AUTO easily ends up filling your /boot partition if you don't clean up old versions regularly, and this script helps make that easier. Checked with Bruce to see that it's fine to add this to the kernel scripts. Maybe people will come up with enhancements, but more importantly, this way I won't misplace this script whenever I install a new machine and start doing custom kernels for it.

2016-02-09MIPS: Fix early CM probingPaul Burton3-18/+1
Commit c014d164f21d ("MIPS: Add platform callback before initializing the L2 cache") added a platform_early_l2_init function in order to allow platforms to probe for the CM before L2 initialisation is performed, so that CM GCRs are available to mips_sc_probe. That commit actually fails to do anything useful, since it checks mips_cm_revision to determine whether it should call mips_cm_probe but the result of mips_cm_revision will always be 0 until mips_cm_probe has been called. Thus the "early" mips_cm_probe call never occurs. Fix this & drop the useless weak platform_early_l2_init function by simply calling mips_cm_probe from setup_arch. For platforms that don't select CONFIG_MIPS_CM this will be a no-op, and for those that do it removes the requirement for them to call mips_cm_probe manually (although doing so isn't harmful for now).

2016-02-09ALSA: hda - Fix bad dereference of jack objectTakashi Iwai7-10/+13
The hda_jack_tbl entries are managed by snd_array for allowing multiple jacks. It's good per se, but the problem is that struct hda_jack_callback keeps the hda_jack_tbl pointer. Since snd_array doesn't preserve each pointer at resizing the array, we can't keep the original pointer but have to deduce the pointer at each time via snd_array_entry() instead. Actually, this resulted in the deference to the wrong pointer on codecs that have many pins such as CS4208. This patch replaces the pointer to the NID value as the search key. As an unexpected good side effect, this even simplifies the code, as only NID is needed in most cases. Cc: <[email protected]> Signed-off-by: Takashi Iwai <[email protected]>
2016-02-09ALSA: timer: Fix race between stop and interruptTakashi Iwai1-0/+4
A slave timer element also unlinks at snd_timer_stop() but it takes only slave_active_lock. When a slave is assigned to a master, however, this may become a race against the master's interrupt handling, eventually resulting in a list corruption. The actual bug could be seen with a syzkaller fuzzer test case in BugLink below. As a fix, we need to take timeri->timer->lock when timer isn't NULL, i.e. assigned to a master, while the assignment to a master itself is protected by slave_active_lock.

2016-02-09locking/lockdep: Fix stack trace caching logicDmitry Vyukov1-6/+10
check_prev_add() caches saved stack trace in static trace variable to avoid duplicate save_trace() calls in dependencies involving trylocks. But that caching logic contains a bug. We may not save trace on first iteration due to early return from check_prev_add(). Then on the second iteration when we actually need the trace we don't save it because we think that we've already saved it. Let check_prev_add() itself control when stack is saved. There is another bug. Trace variable is protected by graph lock. But we can temporary release graph lock during printing. Fix this by invalidating cached stack trace when we release graph lock.

2016-02-09tg3: Fix for tg3 transmit queue 0 timed out when too many gso_segsSiva Reddy Kallam1-6/+19
tg3_tso_bug() can hit a condition where the entire tx ring is not big enough to segment the GSO packet. For example, if MSS is very small, gso_segs can exceed the tx ring size. When we hit the condition, it will cause tx timeout. tg3_tso_bug() is called to handle TSO and DMA hardware bugs. For TSO bugs, if tg3_tso_bug() cannot succeed, we have to drop the packet. For DMA bugs, we can still fall back to linearize the SKB and let the hardware transmit the TSO packet. This patch adds a function tg3_tso_bug_gso_check() to check if there are enough tx descriptors for GSO before calling tg3_tso_bug(). The caller will then handle the error appropriately - drop or lineraize the SKB. v2: Corrected patch description to avoid confusion.

2016-02-08ARM: 8517/1: ICST: avoid arithmetic overflow in icst_hz()Linus Walleij1-2/+6
When trying to set the ICST 307 clock to 25174000 Hz I ran into this arithmetic error: the icst_hz_to_vco() correctly figure out DIVIDE=2, RDW=100 and VDW=99 yielding a frequency of 25174000 Hz out of the VCO. (I replicated the icst_hz() function in a spreadsheet to verify this.) However, when I called icst_hz() on these VCO settings it would instead return 4122709 Hz. This causes an error in the common clock driver for ICST as the common clock framework will call .round_rate() on the clock which will utilize icst_hz_to_vco() followed by icst_hz() suggesting the erroneous frequency, and then the clock gets set to this. The error did not manifest in the old clock framework since this high frequency was only used by the CLCD, which calls clk_set_rate() without first calling clk_round_rate() and since the old clock framework would not call clk_round_rate() before setting the frequency, the correct values propagated into the VCO. After some experimenting I figured out that it was due to a simple arithmetic overflow: the divisor for 24Mhz reference frequency as reference becomes 24000000*2*(99+8)=0x132212400 and the "1" in bit 32 overflows and is lost. But introducing an explicit 64-by-32 bit do_div() and casting the divisor into (u64) we get the right frequency back, and the right frequency gets set. Tested on the ARM Versatile.

This allows another process to arbitrary deplete the original file-openers resource limit for the maximum of open files. Instead the sending processes and its struct cred should be credited. To do so, we add a reference counted struct user_struct pointer to the scm_fp_list and use it to account for the number of inflight unix fds.

DPCM driver is recommended for BYT, CHT based platforms, so if CONFIG_SND_SST_IPC_ACPI is selected then don't compile the BYT Device IDs in common ACPI driver to avoid probe conflicts.
