Fix this by taking the remaining number of jiffies after waiting for driver buffers to drain into account so that the timeout actually becomes a maximum timeout as it is documented to be. Note that this specifically implies tighter timings when closing a port as a consequence of actually honouring the port closing-wait setting for drivers relying on tty_wait_until_sent_from_close (e.g. via tty_port_close_start).

79fbf4a | Johan Hovold | 04 March 2015, 09:39:06 UTC | TTY: fix tty_wait_until_sent on 64-bit machines Fix overflow bug in tty_wait_until_sent on 64-bit machines, where an infinite timeout (0) would be passed to the underlying tty-driver's wait_until_sent-operation as a negative timeout (-1), causing it to return immediately. This manifests itself for example as tcdrain() returning immediately, drivers not honouring the drain flags when setting terminal attributes, or even dropped data on close as a requested infinite closing-wait timeout would be ignored. The first symptom was reported by Asier LLANO who noted that tcdrain() returned prematurely when using the ftdi_sio usb-serial driver. Fix this by passing 0 rather than MAX_SCHEDULE_TIMEOUT (LONG_MAX) to the underlying tty driver. Note that the serial-core wait_until_sent-implementation is not affected by this bug due to a lucky chance (comparison to an unsigned maximum timeout), and neither is the cyclades one that had an explicit check for negative timeouts, but all other tty drivers appear to be affected.

As John Paul correctly points out, we do not care about setting date. If somebody ever changes wall time backwards (by mistake for example), tty timestamps are never updated until the original wall time passes. So check the absolute difference of times and if it large than "8 seconds or so", always update the time. That means we will update immediatelly when changing time. Ergo, CAP_SYS_TIME can foul the check, but it was always that way. Thanks John for serving me this so nicely debugged.

It is possible that if modem control signalling is enabled on a port that doesn't have these pins (e.g. - a simple two wire Tx/Rx port), the driver can hang indefinitely waiting for the state to change.

However, on at91 a timer IRQ is shared with some other devices (including system wakeup ones) and that leads to the unusual combination of flags in question.

45ba215 | Aleksander Morgado | 06 March 2015, 15:14:21 UTC | xhci: fix reporting of 0-sized URBs in control endpoint When a control transfer has a short data stage, the xHCI controller generates two transfer events: a COMP_SHORT_TX event that specifies the untransferred amount, and a COMP_SUCCESS event. But when the data stage is not short, only the COMP_SUCCESS event occurs. Therefore, xhci-hcd must set urb->actual_length to urb->transfer_buffer_length while processing the COMP_SUCCESS event, unless urb->actual_length was set already by a previous COMP_SHORT_TX event. The driver checks this by seeing whether urb->actual_length == 0, but this alone is the wrong test, as it is entirely possible for a short transfer to have an urb->actual_length = 0. This patch changes the xhci driver to rely on a new td->urb_length_set flag, which is set to true when a COMP_SHORT_TX event is received and the URB length updated at that stage. This fixes a bug which affected the HSO plugin, which relies on URBs with urb->actual_length == 0 to halt re-submitting the RX URB in the control endpoint.

3a8b36f | Filipe Manana | 01 March 2015, 20:36:00 UTC | Btrfs: fix data loss in the fast fsync path When using the fast file fsync code path we can miss the fact that new writes happened since the last file fsync and therefore return without waiting for the IO to finish and write the new extents to the fsync log. Here's an example scenario where the fsync will miss the fact that new file data exists that wasn't yet durably persisted: 1. fs_info->last_trans_committed == N - 1 and current transaction is transaction N (fs_info->generation == N); 2. do a buffered write; 3. fsync our inode, this clears our inode's full sync flag, starts an ordered extent and waits for it to complete - when it completes at btrfs_finish_ordered_io(), the inode's last_trans is set to the value N (via btrfs_update_inode_fallback -> btrfs_update_inode -> btrfs_set_inode_last_trans); 4. transaction N is committed, so fs_info->last_trans_committed is now set to the value N and fs_info->generation remains with the value N; 5. do another buffered write, when this happens btrfs_file_write_iter sets our inode's last_trans to the value N + 1 (that is fs_info->generation + 1 == N + 1); 6. transaction N + 1 is started and fs_info->generation now has the value N + 1; 7. transaction N + 1 is committed, so fs_info->last_trans_committed is set to the value N + 1; 8. fsync our inode - because it doesn't have the full sync flag set, we only start the ordered extent, we don't wait for it to complete (only in a later phase) therefore its last_trans field has the value N + 1 set previously by btrfs_file_write_iter(), and so we have: inode->last_trans <= fs_info->last_trans_committed (N + 1) (N + 1) Which made us not log the last buffered write and exit the fsync handler immediately, returning success (0) to user space and resulting in data loss after a crash. This can actually be triggered deterministically and the following excerpt from a testcase I made for xfstests triggers the issue. It moves a dummy file across directories and then fsyncs the old parent directory - this is just to trigger a transaction commit, so moving files around isn't directly related to the issue but it was chosen because running 'sync' for example does more than just committing the current transaction, as it flushes/waits for all file data to be persisted. The issue can also happen at random periods, since the transaction kthread periodicaly commits the current transaction (about every 30 seconds by default). The body of the test is: _scratch_mkfs >> $seqres.full 2>&1 _init_flakey _mount_flakey # Create our main test file 'foo', the one we check for data loss. # By doing an fsync against our file, it makes btrfs clear the 'needs_full_sync' # bit from its flags (btrfs inode specific flags). $XFS_IO_PROG -f -c "pwrite -S 0xaa 0 8K" \ -c "fsync" $SCRATCH_MNT/foo | _filter_xfs_io # Now create one other file and 2 directories. We will move this second file # from one directory to the other later because it forces btrfs to commit its # currently open transaction if we fsync the old parent directory. This is # necessary to trigger the data loss bug that affected btrfs. mkdir $SCRATCH_MNT/testdir_1 touch $SCRATCH_MNT/testdir_1/bar mkdir $SCRATCH_MNT/testdir_2 # Make sure everything is durably persisted. sync # Write more 8Kb of data to our file. $XFS_IO_PROG -c "pwrite -S 0xbb 8K 8K" $SCRATCH_MNT/foo | _filter_xfs_io # Move our 'bar' file into a new directory. mv $SCRATCH_MNT/testdir_1/bar $SCRATCH_MNT/testdir_2/bar # Fsync our first directory. Because it had a file moved into some other # directory, this made btrfs commit the currently open transaction. This is # a condition necessary to trigger the data loss bug. $XFS_IO_PROG -c "fsync" $SCRATCH_MNT/testdir_1 # Now fsync our main test file. If the fsync succeeds, we expect the 8Kb of # data we wrote previously to be persisted and available if a crash happens. # This did not happen with btrfs, because of the transaction commit that # happened when we fsynced the parent directory. $XFS_IO_PROG -c "fsync" $SCRATCH_MNT/foo # Simulate a crash/power loss. _load_flakey_table $FLAKEY_DROP_WRITES _unmount_flakey _load_flakey_table $FLAKEY_ALLOW_WRITES _mount_flakey # Now check that all data we wrote before are available. echo "File content after log replay:" od -t x1 $SCRATCH_MNT/foo status=0 exit The expected golden output for the test, which is what we get with this fix applied (or when running against ext3/4 and xfs), is: wrote 8192/8192 bytes at offset 0 XXX Bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec) wrote 8192/8192 bytes at offset 8192 XXX Bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec) File content after log replay: 0000000 aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa * 0020000 bb bb bb bb bb bb bb bb bb bb bb bb bb bb bb bb * 0040000 Without this fix applied, the output shows the test file does not have the second 8Kb extent that we successfully fsynced: wrote 8192/8192 bytes at offset 0 XXX Bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec) wrote 8192/8192 bytes at offset 8192 XXX Bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec) File content after log replay: 0000000 aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa * 0020000 So fix this by skipping the fsync only if we're doing a full sync and if the inode's last_trans is <= fs_info->last_trans_committed, or if the inode is already in the log. Also remove setting the inode's last_trans in btrfs_file_write_iter since it's useless/unreliable. Also because btrfs_file_write_iter no longer sets inode->last_trans to fs_info->generation + 1, don't set last_trans to 0 if we bail out and don't bail out if last_trans is 0, otherwise something as simple as the following example wouldn't log the second write on the last fsync: 1. write to file 2. fsync file 3. fsync file |--> btrfs_inode_in_log() returns true and it set last_trans to 0 4. write to file |--> btrfs_file_write_iter() no longers sets last_trans, so it remained with a value of 0 5. fsync |--> inode->last_trans == 0, so it bails out without logging the second write A test case for xfstests will be sent soon.

Since the UART driver is correctly disabling IRQs when entering suspend we can safely request the IRQ with IRQF_COND_SUSPEND so that irq core will not complain about mixing IRQF_NO_SUSPEND and !IRQF_NO_SUSPEND. Rework the interrupt handler to wake the system up when an interrupt happens on the DEBUG_UART while the system is suspended.

If the cpuidle driver in use does not provide the new ->enter_freeze callback for any of the idle states, that problem affects suspend-to-idle too, but it is not taken into account after the changes made by commit 381063133246. Fix that by changing the definition of cpuidle_enter_freeze() and re-arranging of the code in cpuidle_idle_call(), so the former does not call cpuidle_enter() any more and the fallback case is handled by cpuidle_idle_call() directly.

In the event that we already have a lease on a file and are going to either upgrade or downgrade it, we skip doing any list insertion or deletion and simply re-call lm_setup on the existing lease. As of commit 8634b51f6ca2 however, we end up calling lm_setup on the lease that was passed in, instead of on the existing lease. This causes us to leak the fasync_struct that was allocated in the event that there was not already an existing one (as it always appeared that there wasn't one).

432ec92 | Boris BREZILLON | 02 March 2015, 09:18:13 UTC | PM / wakeup: export pm_system_wakeup symbol Export pm_system_wakeup function to allow irq handlers to deal with system wakeup. This is needed for shared IRQ lines where one of the handler is registered with IRQF_NO_SUSPEND, while the other ones want to configure it as a wakeup source. In this specific case, irq core does not handle the wakeup process and leave the decision to each irq handler.
