commit c957e8f0 upstream. Once the current message is finished, the driver notifies SPI core about this by calling spi_finalize_current_message(). This function queues next message to be transferred. If there are more messages in the queue, it is possible that the driver is asked to transfer the next message at this point. When spi_finalize_current_message() returns the driver clears the drv_data->cur_chip pointer to NULL. The problem is that if the driver already started the next message clearing drv_data->cur_chip will cause NULL pointer dereference which crashes the kernel like: BUG: unable to handle kernel NULL pointer dereference at 0000000000000048 IP: [<ffffffffa0022bc8>] cs_deassert+0x18/0x70 [spi_pxa2xx_platform] PGD 78bb8067 PUD 37712067 PMD 0 Oops: 0000 [#1] SMP Modules linked in: CPU: 1 PID: 11 Comm: ksoftirqd/1 Tainted: G O 3.18.0-rc4-mjo #5 Hardware name: Intel Corp.

commit 2a7eaea0 upstream. You can't modify the metadata in these modes. It's better to fail these messages immediately than let the block-manager deny write locks on metadata blocks. Otherwise these failed metadata changes will trigger 'needs_check' to get set in the metadata superblock -- requiring repair using the thin_check utility. Signed-off-by:

commit 0fa7b391 upstream. In case userspace attempts to obtain key information for or delete a unicast key, this is currently erroneously rejected unless the driver sets the WIPHY_FLAG_IBSS_RSN flag. Apparently enough drivers do so it was never noticed. Fix that, and while at it fix a potential memory leak: the error path in the get_key() function was placed after allocating a message but didn't free it - move it to a better place. Luckily admin permissions are needed to call this operation. Fixes: e31b8213 ("cfg80211/mac80211: allow per-station GTKs") Signed-off-by:

commit ee8a1a8b upstream. We only support swap file calling nfs_direct_IO. However, application might be able to get to nfs_direct_IO if it toggles O_DIRECT flag during IO and it can deadlock because we grab inode->i_mutex in nfs_file_direct_write(). So return 0 for such case. Then the generic layer will fall back to buffer IO. Signed-off-by:

commit 34e81ad5 upstream. This patch solves deadlock between clock prepare mutex and regmap mutex reported by Tomasz Figa in [1] by implementing solution from [2]: "always leave the clock of the i2c controller in a prepared state". [1] https://lkml.org/lkml/2014/7/2/171 [2] https://lkml.org/lkml/2014/7/2/207 On each i2c transfer handled by s3c24xx_i2c_xfer(), clk_prepare_enable() was called, which calls clk_prepare() then clk_enable(). clk_prepare() takes prepare_lock mutex before proceeding. Note that i2c transfer functions are invoked from many places in kernel, typically with some other additional lock held. It may happen that function on CPU1 (e.g. regmap_update_bits()) has taken a mutex (i.e. regmap lock mutex) then it attempts i2c communication in order to proceed (so it needs to obtain clock related prepare_lock mutex during transfer preparation stage due to clk_prepare() call). At the same time other task on CPU0 wants to operate on clock (e.g. to (un)prepare clock for some other reason) so it has taken prepare_lock mutex. CPU0: CPU1: clk_disable_unused() regulator_disable() clk_prepare_lock() map->lock(map->lock_arg) regmap_read() s3c24xx_i2c_xfer() map->lock(map->lock_arg) clk_prepare_lock() Implemented solution from [2] leaves i2c clock prepared. Preparation is done in s3c24xx_i2c_probe() function. Without this patch, it is immediately unprepared by clk_disable_unprepare() call. I've replaced this call with clk_disable() and I've added clk_unprepare() call in s3c24xx_i2c_remove(). The s3c24xx_i2c_xfer() function now uses clk_enable() instead of clk_prepare_enable() (and clk_disable() instead of clk_unprepare_disable()). Signed-off-by:

commit e69b8d41 upstream. This effectively reverts the last hunk of 392a9dad ("rbd: detect when clone image is flattened"). The problem with parent_overlap != 0 condition is that it's possible and completely valid to have an image with parent_overlap == 0 whose parent state needs to be cleaned up on unmap. The next commit, which drops the "clone image now standalone" logic, opens up another window of opportunity to hit this, but even without it # cat parent-ref.sh #!/bin/bash rbd create --image-format 2 --size 1 foo rbd snap create foo@snap rbd snap protect foo@snap rbd clone foo@snap bar rbd resize --allow-shrink --size 0 bar rbd resize --size 1 bar DEV=$(rbd map bar) rbd unmap $DEV leaves rbd_device/rbd_spec/etc and rbd_client along with ceph_client hanging around. My thinking behind calling rbd_dev_parent_put() unconditionally is that there shouldn't be any requests in flight at that point in time as we are deep into unmap sequence. Hence, even if rbd_dev_unparent() caused by flatten is delayed by in-flight requests, it will have finished by the time we reach rbd_dev_unprobe() caused by unmap, thus turning unconditional rbd_dev_parent_put() into a no-op.

commit 0767e95b upstream. When the last subscriber to a "Through" port has been removed, the subscribed destination ports might still be active, so it would be wrong to send "all sounds off" and "reset controller" events to them. The proper place for such a shutdown would be the closing of the actual MIDI port (and close_substream() in rawmidi.c already can do this). This also fixes a deadlock when dummy_unuse() tries to send events to its own port that is already locked because it is being freed. Reported-by:

commit e6eb2eba upstream. The commit 3b8a3c01 ("powerpc/pseries: Fix endiannes issue in RTAS call from xmon") was fixing an endianness issue in the call made from xmon to RTAS. However, as Michael Ellerman noticed, this fix was not complete, the token value was not byte swapped. This lead to call an unexpected and most of the time unexisting RTAS function, which is silently ignored by RTAS. This fix addresses this hole. Reported-by:

commit e638642b upstream. While being in an ERROR_WARNING state, and receiving further bus error events with error counters still in the ERROR_WARNING range of 97-127 inclusive, the state handling code erroneously reverts back to ERROR_ACTIVE. Per the CAN standard, only revert to ERROR_ACTIVE when the error counters are less than 96. Moreover, in certain Kvaser models, the BUS_ERROR flag is always set along with undefined bits in the M16C status register. Thus use bitwise operators instead of full equality for checking that register against bus errors. Signed-off-by:

commit ded50066 upstream. Upon receiving a hardware event with the BUS_RESET flag set, the driver kills all of its anchored URBs and resets all of its transmit URB contexts. Unfortunately it does so under the context of URB completion handler `kvaser_usb_read_bulk_callback()', which is often called in an atomic context. While the device is flooded with many received error packets, usb_kill_urb() typically sleeps/reschedules till the transfer request of each killed URB in question completes, leading to the sleep in atomic bug. [3] In v2 submission of the original driver patch [1], it was stated that the URBs kill and tx contexts reset was needed since we don't receive any tx acknowledgments later and thus such resources will be locked down forever. Fortunately this is no longer needed since an earlier bugfix in this patch series is now applied: all tx URB contexts are reset upon CAN channel close. [2] Moreover, a BUS_RESET is now treated _exactly_ like a BUS_OFF event, which is the recommended handling method advised by the device manufacturer.

commit 44b82b77 upstream. [backport to 3.12.x: fold in missing MIDR_EL1 recording] Commit d7a49086 (arm64: cpuinfo: print info for all CPUs) attempted to clean up /proc/cpuinfo, but due to concerns regarding further changes was reverted in commit 5e39977e (Revert "arm64: cpuinfo: print info for all CPUs"). There are two major issues with the arm64 /proc/cpuinfo format currently: * The "Features" line describes (only) the 64-bit hwcaps, which is problematic for some 32-bit applications which attempt to parse it. As the same names are used for analogous ISA features (e.g. aes) despite these generally being architecturally unrelated, it is not possible to simply append the 64-bit and 32-bit hwcaps in a manner that might not be misleading to some applications. Various potential solutions have appeared in vendor kernels. Typically the format of the Features line varies depending on whether the task is 32-bit. * Information is only printed regarding a single CPU. This does not match the ARM format, and does not provide sufficient information in big.LITTLE systems where CPUs are heterogeneous. The CPU information printed is queried from the current CPU's registers, which is racy w.r.t. cross-cpu migration. This patch attempts to solve these issues. The following changes are made: * When a task with a LINUX32 personality attempts to read /proc/cpuinfo, the "Features" line contains the decoded 32-bit hwcaps, as with the arm port. Otherwise, the decoded 64-bit hwcaps are shown. This aligns with the behaviour of COMPAT_UTS_MACHINE and COMPAT_ELF_PLATFORM. In the absense of compat support, the Features line is empty. The set of hwcaps injected into a task's auxval are unaffected. * Properties are printed per-cpu, as with the ARM port. The per-cpu information is queried from pre-recorded cpu information (as used by the sanity checks). * As with the previous attempt at fixing up /proc/cpuinfo, the hardware field is removed. The only users so far are 32-bit applications tied to particular boards, so no portable applications should be affected, and this should prevent future tying to particular boards. The following differences remain: * No model_name is printed, as this cannot be queried from the hardware and cannot be provided in a stable fashion. Use of the CPU {implementor,variant,part,revision} fields is sufficient to identify a CPU and is portable across arm and arm64. * The following system-wide properties are not provided, as they are not possible to provide generally. Programs relying on these are already tied to particular (32-bit only) boards: - Hardware - Revision - Serial No software has yet been identified for which these remaining differences are problematic.

commit 046ba642 upstream. This patch drops the arbitrary maximum I/O size limit in sbc_parse_cdb(), which currently for fabric_max_sectors is hardcoded to 8192 (4 MB for 512 byte sector devices), and for hw_max_sectors is a backend driver dependent value. This limit is problematic because Linux initiators have only recently started to honor block limits MAXIMUM TRANSFER LENGTH, and other non-Linux based initiators (eg: MSFT Fibre Channel) can also generate I/Os larger than 4 MB in size. Currently when this happens, the following message will appear on the target resulting in I/Os being returned with non recoverable status: SCSI OP 28h with too big sectors 16384 exceeds fabric_max_sectors: 8192 Instead, drop both [fabric,hw]_max_sector checks in sbc_parse_cdb(), and convert the existing hw_max_sectors into a purely informational attribute used to represent the granuality that backend driver and/or subsystem code is splitting I/Os upon. Also, update FILEIO with an explicit FD_MAX_BYTES check in fd_execute_rw() to deal with the one special iovec limitiation case. v2 changes: - Drop hw_max_sectors check in sbc_parse_cdb() Reported-by:

commit 506787a2 upstream. tcm_loop has the I_T nexus associated with the HBA. This causes commands to become misdirected if the HBA has more than one target portal group; any command is then being sent to the first target portal group instead of the correct one. The nexus needs to be associated with the target portal group instead. Signed-off-by:

commit e7ca2552 upstream. Compat function takes msgtyp argument as u32 and passes it down to do_msgrcv which results in casting to long, thus the sign is lost and we get a big positive number instead. Cast the argument to signed type before passing it down. Signed-off-by:
