The bulkstat fixes are large but necessary. I wouldn't normally push such a rework for a -rcX update, but right now xfsdump can silently create incomplete dumps on 3.17 and it's possible that even xfsrestore won't notice that the dumps were incomplete. Hence we need to get this update into 3.17-stable kernels ASAP. In more detail, the refactoring work I committed in 3.17 has exposed a major hole in our QA coverage. With both xfsdump (the major user of bulkstat) and xfsrestore silently ignoring missing files in the dump/restore process, incomplete dumps were going unnoticed if they were being triggered. Many of the dump/restore filesets were so small that they didn't evenhave a chance of triggering the loop iteration bugs we introduced in 3.17, so we didn't exercise the code sufficiently, either. We have already taken steps to improve QA coverage in xfstests to avoid this happening again, and I've done a lot of manual verification of dump/restore on very large data sets (tens of millions of inodes) of the past week to verify this patch set results in bulkstat behaving the same way as it does on 3.16. Unfortunately, the fixes are not exactly simple - in tracking down the problem historic API warts were discovered (e.g xfsdump has been working around a 20 year old bug in the bulkstat API for the past 10 years) and so that complicated the process of diagnosing and fixing the problems. i.e. we had to fix bugs in the code as well as discover and re-introduce the userspace visible API bugs that we unwittingly "fixed" in 3.17 that xfsdump relied on to work correctly. Summary: - incorrect warnings about i_mutex locking in pagecache_isize_extended() and updates comments to match expected locking - another zero-range bug fix for stray file size updates - a bunch of fixes for regression in the bulkstat code introduced in 3.17" * tag 'xfs-for-linus-3.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: xfs: track bulkstat progress by agino xfs: bulkstat error handling is broken xfs: bulkstat main loop logic is a mess xfs: bulkstat chunk-formatter has issues xfs: bulkstat chunk formatting cursor is broken xfs: bulkstat btree walk doesn't terminate mm: Fix comment before truncate_setsize() xfs: rework zero range to prevent invalid i_size updates mm: Remove false WARN_ON from pagecache_isize_extended() xfs: Check error during inode btree iteration in xfs_bulkstat() xfs: bulkstat doesn't release AGI buffer on error 07 November 2014, 22:08:13 UTC

e4a60d1 Yijing Wang 07 November 2014, 04:05:49 UTC sysfs: driver core: Fix glue dir race condition by gdp_mutex There is a race condition when removing glue directory. It can be reproduced in following test: path 1: Add first child device device_add() get_device_parent() /*find parent from glue_dirs.list*/ list_for_each_entry(k, &dev->class->p->glue_dirs.list, entry) if (k->parent == parent_kobj) { kobj = kobject_get(k); break; } .... class_dir_create_and_add() path2: Remove last child device under glue dir device_del() cleanup_device_parent() cleanup_glue_dir() kobject_put(glue_dir); If path2 has been called cleanup_glue_dir(), but not call kobject_put(glue_dir), the glue dir is still in parent's kset list. Meanwhile, path1 find the glue dir from the glue_dirs.list. Path2 may release glue dir before path1 call kobject_get(). So kernel will report the warning and bug_on. This is a "classic" problem we have of a kref in a list that can be found while the last instance could be removed at the same time. This patch reuse gdp_mutex to fix this race condition.

0027589 Dave Chinner 06 November 2014, 21:33:52 UTC xfs: track bulkstat progress by agino The bulkstat main loop progress is tracked by the "lastino" variable, which is a full 64 bit inode. However, the loop actually works on agno/agino pairs, and so there's a significant disconnect between the rest of the loop and the main cursor. Convert this to use the agino, and pass the agino into the chunk formatting function and convert it too. This gets rid of the inconsistency in the loop processing, and finally makes it simple for us to skip inodes at any point in the loop simply by incrementing the agino cursor. cc: <stable@vger.kernel.org> # 3.17 Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com> 06 November 2014, 21:33:52 UTC
febe3cb Dave Chinner 06 November 2014, 21:31:15 UTC xfs: bulkstat error handling is broken The error propagation is a horror - xfs_bulkstat() returns a rval variable which is only set if there are formatter errors. Any sort of btree walk error or corruption will cause the bulkstat walk to terminate but will not pass an error back to userspace. Worse is the fact that formatter errors will also be ignored if any inodes were correctly formatted into the user buffer. Hence bulkstat can fail badly yet still report success to userspace. This causes significant issues with xfsdump not dumping everything in the filesystem yet reporting success. It's not until a restore fails that there is any indication that the dump was bad and tha bulkstat failed. This patch now triggers xfsdump to fail with bulkstat errors rather than silently missing files in the dump. This now causes bulkstat to fail when the lastino cookie does not fall inside an existing inode chunk.

2b831ac Dave Chinner 06 November 2014, 21:30:58 UTC xfs: bulkstat chunk-formatter has issues The loop construct has issues: - clustidx is completely unused, so remove it. - the loop tries to be smart by terminating when the "freecount" tells it that all inodes are free. Just drop it as in most cases we have to scan all inodes in the chunk anyway. - move the "user buffer left" condition check to the only point where we consume space int eh user buffer. - move the initialisation of agino out of the loop, leaving just a simple loop control logic using the clusteridx. Also, double handling of the user buffer variables leads to problems tracking the current state - use the cursor variables directly rather than keeping local copies and then having to update the cursor before returning. cc: <stable@vger.kernel.org> # 3.17 Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com> 06 November 2014, 21:30:58 UTC
bf4a5af Dave Chinner 06 November 2014, 21:30:30 UTC xfs: bulkstat chunk formatting cursor is broken The xfs_bulkstat_agichunk formatting cursor takes buffer values from the main loop and passes them via the structure to the chunk formatter, and the writes the changed values back into the main loop local variables. Unfortunately, this complex dance is full of corner cases that aren't handled correctly. The biggest problem is that it is double handling the information in both the main loop and the chunk formatting function, leading to inconsistent updates and endless loops where progress is not made. To fix this, push the struct xfs_bulkstat_agichunk outwards to be the primary holder of user buffer information. this removes the double handling in the main loop. Also, pass the last inode processed by the chunk formatter as a separate parameter as it purely an output variable and is not related to the user buffer consumption cursor. Finally, the chunk formatting code is not shared by anyone, so make it local to xfs_itable.c. cc: <stable@vger.kernel.org> # 3.17 Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com> 06 November 2014, 21:30:30 UTC
afa947c Dave Chinner 06 November 2014, 21:29:57 UTC xfs: bulkstat btree walk doesn't terminate The bulkstat code has several different ways of detecting the end of an AG when doing a walk. They are not consistently detected, and the code that checks for the end of AG conditions is not consistently coded. Hence the are conditions where the walk code can get stuck in an endless loop making no progress and not triggering any termination conditions. Convert all the "tmp/i" status return codes from btree operations to a common name (stat) and apply end-of-ag detection to these operations consistently. cc: <stable@vger.kernel.org> # 3.17 Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com> 06 November 2014, 21:29:57 UTC

c4dc304 Francesco Ruggeri 10 October 2014, 20:09:53 UTC tty: Fix pty master poll() after slave closes v2 Commit f95499c3030f ("n_tty: Don't wait for buffer work in read() loop") introduces a race window where a pty master can be signalled that the pty slave was closed before all the data that the slave wrote is delivered. Commit f8747d4a466a ("tty: Fix pty master read() after slave closes") fixed the problem in case of n_tty_read, but the problem still exists for n_tty_poll. This can be seen by running 'for ((i=0; i<100;i++));do ./test.py ;done' where test.py is: import os, select, pty (pid, pty_fd) = pty.fork() if pid == 0: os.write(1, 'This string should be received by parent') else: poller = select.epoll() poller.register( pty_fd, select.EPOLLIN ) ready = poller.poll( 1 * 1000 ) for fd, events in ready: if not events & select.EPOLLIN: print 'missed POLLIN event' else: print os.read(fd, 100) poller.close() The string from the slave is missed several times. This patch takes the same approach as the fix for read and special cases this condition for poll. Tested on 3.16.

e105547 Lars-Peter Clausen 04 November 2014, 17:03:14 UTC staging:iio:ade7758: Fix NULL pointer deref when enabling buffer In older versions of the IIO framework it was possible to pass a completely different set of channels to iio_buffer_register() as the one that is assigned to the IIO device. Commit 959d2952d124 ("staging:iio: make iio_sw_buffer_preenable much more general.") introduced a restriction that requires that the set of channels that is passed to iio_buffer_register() is a subset of the channels assigned to the IIO device as the IIO core will use the list of channels that is assigned to the device to lookup a channel by scan index in iio_compute_scan_bytes(). If it can not find the channel the function will crash. This patch fixes the issue by making sure that the same set of channels is assigned to the IIO device and passed to iio_buffer_register(). Note that we need to remove the IIO_CHAN_INFO_RAW and IIO_CHAN_INFO_SCALE info attributes from the channels since we don't actually want those to be registered.

When a device has both audio and midi interfaces, it gets called twice, and currently the driver tries to release resources at the last call. At this point, the first parent interface has been already deleted, thus deleting a child of the first parent hits such a warning. For fixing this problem, we need to call snd_card_disconnect() and cancel pending operations at the very first disconnect while the release of the whole objects waits until the last disconnect call.

a31b0c6 Kristina Martsenko 05 November 2014, 00:22:41 UTC mmc: core: fix card detection regression Since commit 89168b489915 ("mmc: core: restore detect line inversion semantics"), the SD card on i.MX28 (and possibly other) devices isn't detected and booting stops at: [ 4.120617] Waiting for root device /dev/mmcblk0p3... This is caused by the MMC_CAP2_CD_ACTIVE_HIGH flag being set incorrectly when the host controller doesn't use a GPIO for card detection (but instead uses a dedicated pin). In this case mmc_gpiod_request_cd() will return before assigning to the gpio_invert variable, leaving the variable uninitialized. The variable then gets used to set the flag. This patch fixes the issue by making sure gpio_invert is set to false when a GPIO isn't used. After this patch, i.MX28 boots fine. The MMC_CAP2_RO_ACTIVE_HIGH (write protect) flag is also set incorrectly for the exact same reason (it uses the same uninitialized variable), so this patch fixes that too.

a87fa1d Grant Likely 03 November 2014, 15:15:35 UTC of: Fix overflow bug in string property parsing functions The string property read helpers will run off the end of the buffer if it is handed a malformed string property. Rework the parsers to make sure that doesn't happen. At the same time add new test cases to make sure the functions behave themselves. The original implementations of of_property_read_string_index() and of_property_count_strings() both open-coded the same block of parsing code, each with it's own subtly different bugs. The fix here merges functions into a single helper and makes the original functions static inline wrappers around the helper. One non-bugfix aspect of this patch is the addition of a new wrapper, of_property_read_string_array(). The new wrapper is needed by the device_properties feature that Rafael is working on and planning to merge for v3.19. The implementation is identical both with and without the new static inline wrapper, so it just got left in to reduce the churn on the header file.

c72c553 Stefan Agner 27 October 2014, 16:40:44 UTC ARM: imx: clk-vf610: define PLL's clock tree So far, the required PLL's (PLL1/PLL2/PLL5) have been initialized by boot loader and the kernel code defined fixed rates according to those default configurations. Beginning with the USB PLL7 the code started to initialize the PLL's itself (using imx_clk_pllv3). However, since commit dc4805c2e78ba5a22ea1632f3e3e4ee601a1743b (ARM: imx: remove ENABLE and BYPASS bits from clk-pllv3 driver) imx_clk_pllv3 no longer takes care of the ENABLE and BYPASS bits, hence the USB PLL were not configured correctly anymore. This patch not only fixes those USB PLL's, but also makes use of the imx_clk_pllv3 for all PLL's and alignes the code with the PLL support of the i.MX6 series.

b2108f1 Peter Chen 04 November 2014, 03:14:31 UTC usb: core: notify disconnection when core detects disconnect It is safe to call notify disconnect when the usb core thinks the device is disconnected. This commit also fixes one bug found at below situation: we have not enabled usb wakeup, we do system suspend when there is an usb device at the port, after suspend, we plug out the usb device, then plug in device again. At that time, the nofity disconnect was not called at current code, as the controller doesn't know the usb device was disconnected during the suspend, but USB core knows the port has changed during that periods. So to fix this problem, and let the usb core call notify disconnect.
