2020-02-01cls_rsvp: fix rsvp_policyEric Dumazet1-4/+2
NLA_BINARY can be confusing, since .len value represents the max size of the blob. cls_rsvp really wants user space to provide long enough data for TCA_RSVP_DST and TCA_RSVP_SRC attributes.

2020-02-01vfs: fix do_last() regressionAl Viro1-2/+2
Brown paperbag time: fetching ->i_uid/->i_mode really should've been done from nd->inode. I even suggested that, but the reason for that has slipped through the cracks and I went for dir->d_inode instead - made for more "obvious" patch. Analysis: - at the entry into do_last() and all the way to step_into(): dir (aka nd->path.dentry) is known not to have been freed; so's nd->inode and it's equal to dir->d_inode unless we are already doomed to -ECHILD. inode of the file to get opened is not known. - after step_into(): inode of the file to get opened is known; dir might be pointing to freed memory/be negative/etc. - at the call of may_create_in_sticky(): guaranteed to be out of RCU mode; inode of the file to get opened is known and pinned; dir might be garbage. The last was the reason for the original patch. Except that at the do_last() entry we can be in RCU mode and it is possible that nd->path.dentry->d_inode has already changed under us. In that case we are going to fail with -ECHILD, but we need to be careful; nd->inode is pointing to valid struct inode and it's the same as nd->path.dentry->d_inode in "won't fail with -ECHILD" case, so we should use that.

2020-02-01tracing: Use seq_buf for building dynevent_cmd stringTom Zanussi4-40/+16
The dynevent_cmd commands that build up the command string don't need to do that themselves - there's a seq_buf facility that does pretty much the same thing those command are doing manually, so use it instead.

2020-02-01tracing: Remove check_arg() callbacks from dynevent argsTom Zanussi4-53/+46
It's kind of strange to have check_arg() callbacks as part of the arg objects themselves; it makes more sense to just pass these in when the args are added instead. Remove the check_arg() callbacks from those objects which also means removing the check_arg() args from the init functions, adding them to the add functions and fixing up existing callers.

2020-02-01bcache: add readahead cache policy options via sysfs interfaceColy Li3-5/+37
In year 2007 high performance SSD was still expensive, in order to save more space for real workload or meta data, the readahead I/Os for non-meta data was bypassed and not cached on SSD. In now days, SSD price drops a lot and people can find larger size SSD with more comfortable price. It is unncessary to alway bypass normal readahead I/Os to save SSD space for now. This patch adds options for readahead data cache policies via sysfs file /sys/block/bcache<N>/readahead_cache_policy, the options are, - "all": cache all readahead data I/Os. - "meta-only": only cache meta data, and bypass other regular I/Os. If users want to make bcache continue to only cache readahead request for metadata and bypass regular data readahead, please set "meta-only" to this sysfs file. By default, bcache will back to cache all read- ahead requests now.

2020-02-01bcache: explicity type cast in bset_bkey_last()Coly Li1-1/+2
In bset.h, macro bset_bkey_last() is defined as, bkey_idx((struct bkey *) (i)->d, (i)->keys) Parameter i can be variable type of data structure, the macro always works once the type of struct i has member 'd' and 'keys'. bset_bkey_last() is also used in macro csum_set() to calculate the checksum of a on-disk data structure. When csum_set() is used to calculate checksum of on-disk bcache super block, the parameter 'i' data type is struct cache_sb_disk. Inside struct cache_sb_disk (also in struct cache_sb) the member keys is __u16 type. But bkey_idx() expects unsigned int (a 32bit width), so there is problem when sending parameters via stack to call bkey_idx(). Sparse tool from Intel 0day kbuild system reports this incompatible problem. bkey_idx() is part of user space API, so the simplest fix is to cast the (i)->keys to unsigned int type in macro bset_bkey_last().

2020-02-01bcache: fix memory corruption in bch_cache_accounting_clear()Coly Li1-3/+7
Commit 83ff9318c44ba ("bcache: not use hard coded memset size in bch_cache_accounting_clear()") tries to make the code more easy to understand by removing the hard coded number with following change, void bch_cache_accounting_clear(...) { memset(&acc->total.cache_hits, 0, - sizeof(unsigned long) * 7); + sizeof(struct cache_stats)); } Unfortunately the change was wrong (it also tells us the original code was not easy to correctly understand). The hard coded number 7 is used because in struct cache_stats, 15 struct cache_stats { 16 struct kobject kobj; 17 18 unsigned long cache_hits; 19 unsigned long cache_misses; 20 unsigned long cache_bypass_hits; 21 unsigned long cache_bypass_misses; 22 unsigned long cache_readaheads; 23 unsigned long cache_miss_collisions; 24 unsigned long sectors_bypassed; 25 26 unsigned int rescale; 27 }; only members in LINE 18-24 want to be set to 0. It is wrong to use 'sizeof(struct cache_stats)' to replace 'sizeof(unsigned long) * 7), the memory objects behind acc->total is staled by this change.

Kernel crashes inside QEMU/KVM are observed: kernel BUG at kernel/time/timer.c:1154! BUG_ON(timer_pending(timer) || !timer->function) in add_timer_on(). At the same time another cpu got: general protection fault: 0000 [#1] SMP PTI of poinson pointer 0xdead000000000200 in: __hlist_del at include/linux/list.h:681 (inlined by) detach_timer at kernel/time/timer.c:818 (inlined by) expire_timers at kernel/time/timer.c:1355 (inlined by) __run_timers at kernel/time/timer.c:1686 (inlined by) run_timer_softirq at kernel/time/timer.c:1699 Unfortunately kernel logs are badly scrambled, stacktraces are lost. Printing the timer->function before the BUG_ON() pointed to clocksource_watchdog(). The execution of clocksource_watchdog() can race with a sequence of clocksource_stop_watchdog() .. clocksource_start_watchdog(): expire_timers() detach_timer(timer, true); timer->entry.pprev = NULL; raw_spin_unlock_irq(&base->lock); call_timer_fn clocksource_watchdog() clocksource_watchdog_kthread() or clocksource_unbind() spin_lock_irqsave(&watchdog_lock, flags); clocksource_stop_watchdog(); del_timer(&watchdog_timer); watchdog_running = 0; spin_unlock_irqrestore(&watchdog_lock, flags); spin_lock_irqsave(&watchdog_lock, flags); clocksource_start_watchdog(); add_timer_on(&watchdog_timer, ...); watchdog_running = 1; spin_unlock_irqrestore(&watchdog_lock, flags); spin_lock(&watchdog_lock); add_timer_on(&watchdog_timer, ...); BUG_ON(timer_pending(timer) || !timer->function); timer_pending() -> true BUG() I.e. inside clocksource_watchdog() watchdog_timer could be already armed. Check timer_pending() before calling add_timer_on(). This is sufficient as all operations are synchronized by watchdog_lock.

2020-02-01x86/apic/msi: Plug non-maskable MSI affinity raceThomas Gleixner6-4/+163
Evan tracked down a subtle race between the update of the MSI message and the device raising an interrupt internally on PCI devices which do not support MSI masking. The update of the MSI message is non-atomic and consists of either 2 or 3 sequential 32bit wide writes to the PCI config space. - Write address low 32bits - Write address high 32bits (If supported by device) - Write data When an interrupt is migrated then both address and data might change, so the kernel attempts to mask the MSI interrupt first. But for MSI masking is optional, so there exist devices which do not provide it. That means that if the device raises an interrupt internally between the writes then a MSI message is sent built from half updated state. On x86 this can lead to spurious interrupts on the wrong interrupt vector when the affinity setting changes both address and data. As a consequence the device interrupt can be lost causing the device to become stuck or malfunctioning. Evan tried to handle that by disabling MSI accross an MSI message update. That's not feasible because disabling MSI has issues on its own: If MSI is disabled the PCI device is routing an interrupt to the legacy INTx mechanism. The INTx delivery can be disabled, but the disablement is not working on all devices. Some devices lose interrupts when both MSI and INTx delivery are disabled. Another way to solve this would be to enforce the allocation of the same vector on all CPUs in the system for this kind of screwed devices. That could be done, but it would bring back the vector space exhaustion problems which got solved a few years ago. Fortunately the high address (if supported by the device) is only relevant when X2APIC is enabled which implies interrupt remapping. In the interrupt remapping case the affinity setting is happening at the interrupt remapping unit and the PCI MSI message is programmed only once when the PCI device is initialized. That makes it possible to solve it with a two step update: 1) Target the MSI msg to the new vector on the current target CPU 2) Target the MSI msg to the new vector on the new target CPU In both cases writing the MSI message is only changing a single 32bit word which prevents the issue of inconsistency. After writing the final destination it is necessary to check whether the device issued an interrupt while the intermediate state #1 (new vector, current CPU) was in effect. This is possible because the affinity change is always happening on the current target CPU. The code runs with interrupts disabled, so the interrupt can be detected by checking the IRR of the local APIC. If the vector is pending in the IRR then the interrupt is retriggered on the new target CPU by sending an IPI for the associated vector on the target CPU. This can cause spurious interrupts on both the local and the new target CPU. 1) If the new vector is not in use on the local CPU and the device affected by the affinity change raised an interrupt during the transitional state (step #1 above) then interrupt entry code will ignore that spurious interrupt. The vector is marked so that the 'No irq handler for vector' warning is supressed once. 2) If the new vector is in use already on the local CPU then the IRR check might see an pending interrupt from the device which is using this vector. The IPI to the new target CPU will then invoke the handler of the device, which got the affinity change, even if that device did not issue an interrupt 3) If the new vector is in use already on the local CPU and the device affected by the affinity change raised an interrupt during the transitional state (step #1 above) then the handler of the device which uses that vector on the local CPU will be invoked. expose issues in device driver interrupt handlers which are not prepared to handle a spurious interrupt correctly. This not a regression, it's just exposing something which was already broken as spurious interrupts can happen for a lot of reasons and all driver handlers need to be able to deal with them.

2020-01-31Input: synaptics-rmi4 - switch to reduced reporting modeLucas Stach1-0/+14
When the distance thresholds are set the controller must be in reduced reporting mode for them to have any effect on the interrupt generation. This has a potentially large impact on the number of events the host needs to process.

2020-01-31drm/tegra: sor: Initialize runtime PM before useThierry Reding1-15/+17
Commit fd67e9c6ed5a ("drm/tegra: Do not implement runtime PM") replaced the generic runtime PM usage by a host1x bus-specific implementation in order to work around some assumptions baked into runtime PM that are in conflict with the requirements in the Tegra DRM driver. Unfortunately the new runtime PM callbacks are not setup yet at the time when the SOR driver first needs to resume the device to register the SOR pad clock, and accesses to register will cause the system to hang. Note that this only happens on Tegra124 and Tegra210 because those are the only SoCs where the SOR pad clock is registered from the SOR driver. Later generations use a SOR pad clock provided by the BPMP. Fix this by moving the registration of the SOR pad clock after the host1x client has been registered. That's somewhat suboptimal because this could potentially, though it's very unlikely, cause the Tegra DRM to be probed if the SOR happens to be the last subdevice to register, only to be immediately removed again if the SOR pad output clock fails to register. That's just a minor annoyance, though, and doesn't justify implementing a workaround. Fixes: fd67e9c6ed5a ("drm/tegra: Do not implement runtime PM") Signed-off-by: Thierry Reding <[email protected]>
