The reason I'm sending this and not Ben should be obvious from the first commit below - SGI has stepped down from the XFS maintainership role. As such, I'd like to take another opportunity to thank them for their many years of effort maintaining XFS and supporting the XFS community that they developed from the ground up. So I haven't had time to work things like signed tags into my workflows yet, so this is just a repo branch I'm asking you to pull from. And yes, I named the branch -rc4 because I wanted the fixes in rc4, not because the branch was for merging into -rc3. Probably not right, either. Anyway, I should have everything sorted out by the time the next merge window comes around. If there's anything that you don't like in the pull req, feel free to flame me unmercifully.

Merely reverting the fix and waiting until v3.15 isn't a good option because there is code in v3.14 that depends on the revised behaviour to boot.

4df1638 | Steven Rostedt | 19 February 2014, 18:53:35 UTC | sched/deadline: Fix overflow to handle period==0 and deadline!=0 While debugging the crash with the bad nr_running accounting, I hit another bug where, after running my sched deadline test, I was getting failures to take a CPU offline. It was giving me a -EBUSY error. Adding a bunch of trace_printk()s around, I found that the cpu notifier that called sched_cpu_inactive() was returning a failure. The overflow value was coming up negative? Talking this over with Juri, the problem is that the total_bw update was suppose to be made by dl_overflow() which, during my tests, seemed to not be called. Adding more trace_printk()s, it wasn't that it wasn't called, but it exited out right away with the check of new_bw being equal to p->dl.dl_bw. The new_bw calculates the ratio between period and runtime. The bug is that if you set a deadline, you do not need to set a period if you plan on the period being equal to the deadline. That is, if period is zero and deadline is not, then the system call should set the period to be equal to the deadline. This is done elsewhere in the code. The fix is easy, check if period is set, and if it is not, then use the deadline.

3d5f35b | Juri Lelli | 20 February 2014, 08:19:39 UTC | sched/deadline: Fix bad accounting of nr_running Rostedt writes: My test suite was locking up hard when enabling mmiotracer. This was due to the mmiotracer placing all but one CPU offline. I found this out when I was able to reproduce the bug with just my stress-cpu-hotplug test. This bug baffled me because it would not always trigger, and would only trigger on the first run after boot up. The stress-cpu-hotplug test would crash hard the first run, or never crash at all. But a new reboot may cause it to crash on the first run again. I spent all week bisecting this, as I couldn't find a consistent reproducer. I finally narrowed it down to the sched deadline patches, and even more peculiar, to the commit that added the sched deadline boot up self test to the latency tracer. Then it dawned on me to what the bug was. All it took was to run a task under sched deadline to screw up the CPU hot plugging. This explained why it would lock up only on the first run of the stress-cpu-hotplug test. The bug happened when the boot up self test of the schedule latency tracer would test a deadline task. The deadline task would corrupt something that would cause CPU hotplug to fail. If it didn't corrupt it, the stress test would always work (there's no other sched deadline tasks that would run to cause problems). If it did corrupt on boot up, the first test would lockup hard. I proved this theory by running my deadline test program on another box, and then run the stress-cpu-hotplug test, and it would now consistently lock up. I could run stress-cpu-hotplug over and over with no problem, but once I ran the deadline test, the next run of the stress-cpu-hotplug would lock hard. After adding lots of tracing to the code, I found the cause. The function tracer showed that migrate_tasks() was stuck in an infinite loop, where rq->nr_running never equaled 1 to break out of it. When I added a trace_printk() to see what that number was, it was 335 and never decrementing! Looking at the deadline code I found: static void __dequeue_task_dl(struct rq *rq, struct task_struct *p, int flags) { dequeue_dl_entity(&p->dl); dequeue_pushable_dl_task(rq, p); } static void dequeue_task_dl(struct rq *rq, struct task_struct *p, int flags) { update_curr_dl(rq); __dequeue_task_dl(rq, p, flags); dec_nr_running(rq); } And this: if (dl_runtime_exceeded(rq, dl_se)) { __dequeue_task_dl(rq, curr, 0); if (likely(start_dl_timer(dl_se, curr->dl.dl_boosted))) dl_se->dl_throttled = 1; else enqueue_task_dl(rq, curr, ENQUEUE_REPLENISH); if (!is_leftmost(curr, &rq->dl)) resched_task(curr); } Notice how we call __dequeue_task_dl() and in the else case we call enqueue_task_dl()? Also notice that dequeue_task_dl() has underscores where enqueue_task_dl() does not. The enqueue_task_dl() calls inc_nr_running(rq), but __dequeue_task_dl() does not. This is where we get nr_running out of sync. [snip] Another point where nr_running can get out of sync is when the dl_timer fires: dl_se->dl_throttled = 0; if (p->on_rq) { enqueue_task_dl(rq, p, ENQUEUE_REPLENISH); if (task_has_dl_policy(rq->curr)) check_preempt_curr_dl(rq, p, 0); else resched_task(rq->curr); This patch does two things: - correctly accounts for throttled tasks (that are now considered !running); - fixes the bug, updating nr_running from {inc,dec}_dl_tasks(), since we risk to update it twice in some situations (e.g., a task is dequeued while it has exceeded its budget).

215a14c | Kevin Hao | 19 February 2014, 08:15:45 UTC | of: reimplement the matching method for __of_match_node() In the current implementation of __of_match_node(), it will compare each given match entry against all the node's compatible strings with of_device_is_compatible(). To achieve multiple compatible strings per node with ordering from specific to generic, this requires given matches to be ordered from specific to generic. For most of the drivers this is not true and also an alphabetical ordering is more sane there. Therefore, we define a following priority order for the match, and then scan all the entries to find the best match. 1. specific compatible && type && name 2. specific compatible && type 3. specific compatible && name 4. specific compatible 5. general compatible && type && name 6. general compatible && type 7. general compatible && name 8. general compatible 9. type && name 10. type 11. name v5: Fix nested locking bug v4: Short-circuit failure cases instead of mucking with score, and remove extra __of_device_is_compatible() wrapper stub. Move scoring logic directly into __of_device_is_compatible() v3: Also need to bail out when there does have a compatible member in match entry, but it doesn't match with the device node's compatible. v2: Fix the bug such as we get the same score for the following two match entries with the empty node 'name2 { };' struct of_device_id matches[] = { {.name = "name2", }, {.name = "name2", .type = "type1", }, {} }; Signed-off-by: Kevin Hao <haokexin@gmail.com> [grant.likely: added v4 changes] Signed-off-by: Grant Likely <grant.likely@linaro.org> Tested-by: Paul Gortmaker <paul.gortmaker@windriver.com> Tested-by: Stephen Chivers <schivers@csc.com> Tested-by: Sachin Kamat <sachin.kamat@linaro.org> | 20 February 2014, 11:50:58 UTC |

bd8ba20 | Hans de Goede | 13 February 2014, 15:32:51 UTC | ACPI / video: Filter the _BCL table for duplicate brightness values Some devices have duplicate entries in there brightness levels table, ie on my Dell Latitude E6430 the table looks like this: [ 3.686060] acpi backlight index 0, val 80 [ 3.686095] acpi backlight index 1, val 50 [ 3.686122] acpi backlight index 2, val 5 [ 3.686147] acpi backlight index 3, val 5 [ 3.686172] acpi backlight index 4, val 5 [ 3.686197] acpi backlight index 5, val 5 [ 3.686223] acpi backlight index 6, val 5 [ 3.686248] acpi backlight index 7, val 5 [ 3.686273] acpi backlight index 8, val 6 [ 3.686332] acpi backlight index 9, val 7 [ 3.686356] acpi backlight index 10, val 8 [ 3.686380] acpi backlight index 11, val 9 etc. Notice that brightness values 0-5 are all mapped to 5. This means that if userspace writes any value between 0 and 5 to the brightness sysfs attribute and then reads it, it will always return 0, which is somewhat unexpected. This is a problem for ie gnome-settings-daemon, which uses read-modify-write logic when the users presses the brightness up or down keys. This is done this way to take brightness changes from other sources into account. On this specific laptop what happens once the brightness has been set to 0, is that gsd reads 0, adds 5, writes 5, and on the next brightness up key press again reads 0, so things get stuck at the lowest brightness setting. Filtering out the duplicate table entries, makes any write to brightness read back as the written value as one would expect, fixing this.

5ae8aab | Stephen Boyd | 17 February 2014, 18:45:36 UTC | sched_clock: Prevent callers from seeing half-updated data The generic sched_clock registration function was previously done lockless, due to the fact that it was expected to be called only once. However, now there are systems that may register multiple sched_clock sources, for which the lack of locking has casued problems: If two sched_clock sources are registered we may end up in a situation where a call to sched_clock() may be accessing the epoch cycle count for the old counter and the cycle count for the new counter. This can lead to confusing results where sched_clock() values jump and then are reset to 0 (due to the way the registration function forces the epoch_ns to be 0). Fix this by reorganizing the registration function to hold the seqlock for as short a time as possible while we update the clock_data structure for a new counter. We also put any accumulated time into epoch_ns instead of resetting the time to 0 so that the clock doesn't reset after each successful registration.

5ef11eb | Eric Sandeen | 19 February 2014, 04:39:35 UTC | xfs: limit superblock corruption errors to actual corruption Today, if xfs_sb_read_verify xfs_sb_verify xfs_mount_validate_sb detects superblock corruption, it'll be extremely noisy, dumping 2 stacks, 2 hexdumps, etc. This is because we call XFS_CORRUPTION_ERROR in xfs_mount_validate_sb as well as in xfs_sb_read_verify. Also, *any* errors in xfs_mount_validate_sb which are not corruption per se; things like too-big-blocksize, bad version, bad magic, v1 dirs, rw-incompat etc - things which do not return EFSCORRUPTED - will still do the whole XFS_CORRUPTION_ERROR spew when xfs_sb_read_verify sees any error at all. And it suggests to the user that they should run xfs_repair, even if the root cause of the mount failure is a simple incompatibility. I'll submit that the probably-not-corrupted errors don't warrant this much noise, so this patch removes the warning for anything other than EFSCORRUPTED returns, and replaces the lower-level XFS_CORRUPTION_ERROR with an xfs_notice().

daba542 | Eric Sandeen | 19 February 2014, 04:39:16 UTC | xfs: skip verification on initial "guess" superblock read When xfs_readsb() does the very first read of the superblock, it makes a guess at the length of the buffer, based on the sector size of the underlying storage. This may or may not match the filesystem sector size in sb_sectsize, so we can't i.e. do a CRC check on it; it might be too short. In fact, mounting a filesystem with sb_sectsize larger than the device sector size will cause a mount failure if CRCs are enabled, because we are checksumming a length which exceeds the buffer passed to it. So always read twice; the first time we read with NULL buffer ops to skip verification; then set the proper read length, hook up the proper verifier, and give it another go. Once we are sure that we've got the right buffer length, we can also use bp->b_length in the xfs_sb_read_verify, rather than the less-trusted on-disk sectorsize for secondary superblocks. Before this we ran the risk of passing junk to the crc32c routines, which didn't always handle extreme values.

c327476 | Srivatsa S. Bhat | 17 February 2014, 10:48:21 UTC | cpufreq: powernow-k8: Initialize per-cpu data-structures properly The powernow-k8 driver maintains a per-cpu data-structure called powernow_data that is used to perform the frequency transitions. It initializes this data structure only for the policy->cpu. So, accesses to this data structure by other CPUs results in various problems because they would have been uninitialized. Specifically, if a cpu (!= policy->cpu) invokes the drivers' ->get() function, it returns 0 as the KHz value, since its per-cpu memory doesn't point to anything valid. This causes problems during suspend/resume since cpufreq_update_policy() tries to enforce this (0 KHz) as the current frequency of the CPU, and this madness gets propagated to adjust_jiffies() as well. Eventually, lots of things start breaking down, including the r8169 ethernet card, in one particularly interesting case reported by Pierre Ossman. Fix this by initializing the per-cpu data-structures of all the CPUs in the policy appropriately.
