2014-04-30tcp: increment retransmit counters in tlp and fast openEric Dumazet
Both TLP and Fast Open call __tcp_retransmit_skb() instead of tcp_retransmit_skb() to avoid changing tp->retrans_out. This has the side effect of missing SNMP counters increments as well as tcp_info tcpi_total_retrans updates. Fix this by moving the stats increments of into __tcp_retransmit_skb() Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Nandita Dukkipati <nanditad@google.com> Acked-by: Neal Cardwell <ncardwell@google.com> Signed-off-by: David S.

sgdma_descrip is a function name as well as the name of a struct. In sgdma_initialize(), we should initialize the descriptor length field with the actual length of a descriptor not with the size of the function. In order to prevent such things from happening in the future, rename the function to sgdma_setup_descrip().

2014-04-30clk: Fix slab corruption in clk_unregister()Stephen Boyd
When a clock is unregsitered, we iterate over the list of children and reparent them to NULL (i.e. orphan list). While iterating the list, we should use the safe iterators because the children list for this clock is changing when we reparent the children to NULL. Failure to iterate safely can lead to slab corruption like this: ============================================================================= BUG kmalloc-128 (Not tainted): Poison overwritten ----------------------------------------------------------------------------- Disabling lock debugging due to kernel taint INFO: 0xed0c4900-0xed0c4903.

2014-04-30clk: Fix double free due to devm_clk_register()Stephen Boyd
Now that clk_unregister() frees the struct clk we're unregistering we'll free memory twice: first we'll call kfree() in __clk_release() with an address kmalloc doesn't know about and second we'll call kfree() in the devres layer. Remove the allocation of struct clk in devm_clk_register() and let clk_release() handle it.

2014-04-30clk: socfpga: fix clock driver for 3.15Dinh Nguyen
commit [1771b10d6 clk: respect the clock dependencies in of_clk_init] exposed a flaw in the socfpga clock driver and prevents the platform from booting on 3.15-rc1. Because the "altr,clk-mgr" is not really a clock, it should not be using CLK_OF_DECLARE, instead we should be mapping the clk-mgr's base address one of the functional clock init function. Use the socfpga_pll_init function to map the clk_mgr_base_addr as this clock should always be initialized first.

There are some corner cases where the driver could get stuck with a full tid queue that is paused, leading to a software tx queue hang. Since the tx queueing rework, pausing per-tid queues on aggregation session setup is no longer necessary. The driver will assign sequence numbers to buffered frames when a new session is established, in order to get the correct starting sequence number. mac80211 prevents new frames from entering the queue during setup.

2014-04-30ath9k_hw: do not lower ANI setting below default on AR913xFelix Fietkau
When the amount of noise fluctuates strongly, low immunity settings can sometimes disrupt signal detection on AR913x chips. When that happens, no OFDM/CCK errors are reported anymore, and ANI tunes the radio to the lowest immunity settings. Usually rx/tx fails as well in that case. To fix this, keep noise immunity settings at or above ANI default level, which will keep radio parameters at or above INI values. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2014-04-30perf x86: Fix perf to use non-executable stack, againMathias Krause
arch/x86/tests/regs_load.S is missing the linker note about the stack requirements, therefore making the linker fall back to an executable stack. As this object gets linked against the final perf binary, it'll needlessly end up with an executable stack. Fix this by adding the appropriate linker note. Also add a global linker flag to prevent future regressions, as suggested by Jiri. This way perf won't get an executable stack even if we fail to add the .GNU-stack linker note to future assembler files. Though, doing so might create regressions the other way around, when (statically) linking against libraries needing an executable stack. But, apparently, regressing in that direction is wanted as it is an indicator of poor code quality -- or just missing linker notes.

2014-04-30perf machine: Search for modules in %s/lib/modules/%sRichard Yao
Modules installed outside of the kernel's build system should go into "%s/lib/modules/%s/extra", but at present, perf will only look at them when they are in "%s/lib/modules/%s/kernel". Lets encourage good citizenship by relaxing this requirement to "%s/lib/modules/%s". This way open source modules that are out-of-tree have no incentive to start populating a directory reserved for in-kernel modules and I can stop hex-editing my system's perf binary when profiling OSS out-of-tree modules. Feedback from Namhyung Kim correctly revealed that the hex-edits that I had been doing meant that perf was also traversing the build and source symlinks in %s/lib/modules/%s. That is undesireable, so we explicitly exclude them from traversal with a minor tweak to the traversal routine.

2014-04-30timer: Prevent overflow in apply_slackJiri Bohac
On architectures with sizeof(int) < sizeof (long), the computation of mask inside apply_slack() can be undefined if the computed bit is > 32. E.g. with: expires = 0xffffe6f5 and slack = 25, we get: expires_limit = 0x20000000e bit = 33 mask = (1 << 33) - 1 /* undefined */ On x86, mask becomes 1 and and the slack is not applied properly. On s390, mask is -1, expires is set to 0 and the timer fires immediately. Use 1UL << bit to solve that issue.

2014-04-30hrtimer: Prevent remote enqueue of leftmost timersLeon Ma
If a cpu is idle and starts an hrtimer which is not pinned on that same cpu, the nohz code might target the timer to a different cpu. In the case that we switch the cpu base of the timer we already have a sanity check in place, which determines whether the timer is earlier than the current leftmost timer on the target cpu. In that case we enqueue the timer on the current cpu because we cannot reprogram the clock event device on the target. If the timers base is already the target CPU we do not have this sanity check in place so we enqueue the timer as the leftmost timer in the target cpus rb tree, but we cannot reprogram the clock event device on the target cpu. So the timer expires late and subsequently prevents the reprogramming of the target cpu clock event device until the previously programmed event fires or a timer with an earlier expiry time gets enqueued on the target cpu itself. Add the same target check as we have for the switch base case and start the timer on the current cpu if it would become the leftmost timer on the target.

2014-04-30hrtimer: Prevent all reprogramming if hang detectedStuart Hayes
If the last hrtimer interrupt detected a hang it sets hang_detected=1 and programs the clock event device with a delay to let the system make progress. If hang_detected == 1, we prevent reprogramming of the clock event device in hrtimer_reprogram() but not in hrtimer_force_reprogram(). This can lead to the following situation: hrtimer_interrupt() hang_detected = 1; program ce device to Xms from now (hang delay) We have two timers pending: T1 expires 50ms from now T2 expires 5s from now Now T1 gets canceled, which causes hrtimer_force_reprogram() to be invoked, which in turn programs the clock event device to T2 (5 seconds from now). Any hrtimer_start after that will not reprogram the hardware due to hang_detected still being set. So we effectivly block all timers until the T2 event fires and cleans up the hang situation. Add a check for hang_detected to hrtimer_force_reprogram() which prevents the reprogramming of the hang delay in the hardware timer. The subsequent hrtimer_interrupt will resolve all outstanding issues.

2014-04-29ACPI / EC: Process rather than discard events in acpi_ec_clearKieran Clancy
Address a regression caused by commit ad332c8a4533: (ACPI / EC: Clear stale EC events on Samsung systems) After the earlier patch, there was found to be a race condition on some earlier Samsung systems (N150/N210/N220). The function acpi_ec_clear was sometimes discarding a new EC event before its GPE was triggered by the system. In the case of these systems, this meant that the "lid open" event was not registered on resume if that was the cause of the wake, leading to problems when attempting to close the lid to suspend again. After testing on a number of Samsung systems, both those affected by the previous EC bug and those affected by the race condition, it seemed that the best course of action was to process rather than discard the events. On Samsung systems which accumulate stale EC events, there does not seem to be any adverse side-effects of running the associated _Q methods. This patch adds an argument to the static function acpi_ec_sync_query so that it may be used within the acpi_ec_clear loop in place of acpi_ec_query_unlocked which was used previously. With thanks to Stefan Biereigel for reporting the issue, and for all the people who helped test the new patch on affected systems.

commit 0eba801b64cc8284d9024c7ece30415a2b981a72 tried to fix a race where nat initialisation can happen after ctnetlink-created conntrack has been created. However, it causes the nat module(s) to be loaded needlessly on systems that are not using NAT. Fortunately, we do not have to create null bindings in that case. conntracks injected via ctnetlink always have the CONFIRMED bit set, which prevents addition of the nat extension in nf_nat_ipv4/6_fn(). We only need to make sure that either no nat extension is added or that we've created both src and dst manips.

2014-04-29drivercore: deferral race condition fixGrant Likely
When the kernel is built with CONFIG_PREEMPT it is possible to reach a state when all modules loaded but some driver still stuck in the deferred list and there is a need for external event to kick the deferred queue to probe these drivers. The issue has been observed on embedded systems with CONFIG_PREEMPT enabled, audio support built as modules and using nfsroot for root filesystem. The following log fragment shows such sequence when all audio modules were loaded but the sound card is not present since the machine driver has failed to probe due to missing dependency during it's probe. The board is am335x-evmsk (McASP<->tlv320aic3106 codec) with davinci-evm machine driver: ... [ 12.615118] davinci-mcasp 4803c000.mcasp: davinci_mcasp_probe: ENTER [ 12.719969] davinci_evm sound.3: davinci_evm_probe: ENTER [ 12.725753] davinci_evm sound.3: davinci_evm_probe: snd_soc_register_card [ 12.753846] davinci-mcasp 4803c000.mcasp: davinci_mcasp_probe: snd_soc_register_component [ 12.922051] davinci-mcasp 4803c000.mcasp: davinci_mcasp_probe: snd_soc_register_component DONE [ 12.950839] davinci_evm sound.3: ASoC: platform (null) not registered [ 12.957898] davinci_evm sound.3: davinci_evm_probe: snd_soc_register_card DONE (-517) [ 13.099026] davinci-mcasp 4803c000.mcasp: Kicking the deferred list [ 13.177838] davinci-mcasp 4803c000.mcasp: really_probe: probe_count = 2 [ 13.194130] davinci_evm sound.3: snd_soc_register_card failed (-517) [ 13.346755] davinci_mcasp_driver_init: LEAVE [ 13.377446] platform sound.3: Driver davinci_evm requests probe deferral [ 13.592527] platform sound.3: really_probe: probe_count = 0 In the log the machine driver enters it's probe at 12.719969 (this point it has been removed from the deferred lists). McASP driver already executing it's probing (since 12.615118). The machine driver tries to construct the sound card (12.950839) but did not found one of the components so it fails. After this McASP driver registers all the ASoC components (the machine driver still in it's probe function after it failed to construct the card) and the deferred work is prepared at 13.099026 (note that this time the machine driver is not in the lists so it is not going to be handled when the work is executing). Lastly the machine driver exit from it's probe and the core places it to the deferred list but there will be no other driver going to load and the deferred queue is not going to be kicked again - till we have external event like connecting USB stick, etc. The proposed solution is to try the deferred queue once more when the last driver is asking for deferring and we had drivers loaded while this last driver was probing. This way we can avoid drivers stuck in the deferred queue.

2014-04-29ARM: common: edma: Fix xbar mappingThomas Gleixner
This is another great example of trainwreck engineering: commit 2646a0e529 (ARM: edma: Add EDMA crossbar event mux support) added support for using EDMA on peripherals which have no direct EDMA event mapping. The code compiles and does not explode in your face, but that's it. 1) Reading an u16 array from an u32 device tree array simply does not work. Even if the function is named "edma_of_read_u32_to_s16_array". It merily calls of_property_read_u16_array. So the resulting 16bit array will have every other entry = 0. 2) The DT entry for the xbar registers related to xbar has length 0x10 instead of the real length: 0xfd0 - 0xf90 = 0x40. Not a real problem as it does not cross a page boundary, but wrong nevertheless. 3) But none of this matters as the mapping never happens: After reading nonsense edma_of_read_u32_to_s16_array() invalidates the first array entry pair, so nobody can ever notice the braindamage by immediate explosion. Seems the QA criteria for this code was solely not to explode when someone adds edma-xbar-event-map entries to the DT. Goal achieved, congratulations! Not really helpful if someone wants to use edma on a device which requires a xbar mapping. Fix the issues by: - annotating the device tree entry with "/bits/ 16" as documented in the of_property_read_u16_array kernel doc - make the size of the xbar register mapping correct - invalidating the end of the array and not the start This convoluted mess wants to be completely rewritten as there is no point to keep the xbar_chan array memory and the iomapping of the xbar regs around forever. Marking the xbar mapped channels as used should be done right there. But that's a different issue and this patch is small enough to make it work and allows a simple backport for stable.
