commit d5d0689a upstream. This fixes a pretty ancient bug that hasn't manifested itself until now. The scratchbuf for command queue is allocated only for 32 slots but is accessed with the queue write pointer - which can be up to 256. Since the scratch buf size was 16 and there are up to 256 TFDs we never passed a page boundary when accessing the scratch buffer, but when attempting to increase the size of the scratch buffer a panic was quick to follow when trying to access the address resulted in a page boundary.

commit 5b9554dc upstream. If s_reserved_gdt_blocks is extremely large, it's possible for ext4_init_block_bitmap(), which is called when ext4 sets up an uninitialized block bitmap, to corrupt random kernel memory. Add the same checks which e2fsck has --- it must never be larger than blocksize / sizeof(__u32) --- and then add a backup check in ext4_init_block_bitmap() in case the superblock gets modified after the file system is mounted.

commit cbef1e10 upstream. The orig_ifinfo reference counter for last_bonding_candidate in batadv_orig_node has to be reduced when an originator node is released.

commit 15c2ed75 upstream. The replacement of last_bonding_candidate in batadv_orig_node has to be an atomic operation. Otherwise it is possible that the reference counter of a batadv_orig_ifinfo is reduced which was no longer the last_bonding_candidate when the new candidate is added. This can either lead to an invalid memory access or to reference leaks which make it impossible to an interface which was added to batman-adv.

commit 3db0decf upstream. The pointer batadv_bla_claim::backbone_gw can be changed at any time. Therefore, access to it must be protected to ensure that two function accessing the same backbone_gw are actually accessing the same. This is especially important when the crc_lock is used or when the backbone_gw of a claim is exchanged. Not doing so leads to invalid memory access and/or reference leaks.

commit 5a1dd8a4 upstream. We have found some networks in which nodes were constantly requesting other nodes BLA claim tables to synchronize, just to ask for that again once completed. The reason was that the crc checksum of the asked nodes were out of sync due to missing locking and multiple writes to the same crc checksum when adding/removing entries. Therefore the asked nodes constantly reported the wrong crc, which caused repeating requests. To avoid multiple functions changing a backbone gateways crc entry at the same time, lock it using a spinlock. Signed-off-by:

commit 6a7fd522 upstream. If ext4_fill_super() fails early, it's possible for ext4_evict_inode() to call ext4_should_journal_data() before superblock options and flags are fully set up. In that case, the iput() on the journal inode can end up causing a BUG(). Work around this problem by reordering the tests so we only call ext4_should_journal_data() after we know it's not the journal inode.

commit 646caa9c upstream. Commit 06bd3c36 (ext4: fix data exposure after a crash) uncovered a deadlock in ext4_writepages() which was previously much harder to hit. After this commit xfstest generic/130 reproduces the deadlock on small filesystems. The problem happens when ext4_do_update_inode() sets LARGE_FILE feature and marks current inode handle as synchronous. That subsequently results in ext4_journal_stop() called from ext4_writepages() to block waiting for transaction commit while still holding page locks, reference to io_end, and some prepared bio in mpd structure each of which can possibly block transaction commit from completing and thus results in deadlock. Fix the problem by releasing page locks, io_end reference, and submitting prepared bio before calling ext4_journal_stop(). [ Changed to defer the call to ext4_journal_stop() only if the handle is synchronous. --tytso ] Reported-and-tested-by:

commit f70749ca upstream. An extent with lblock = 4294967295 and len = 1 will pass the ext4_valid_extent() test: ext4_lblk_t last = lblock + len - 1; if (len == 0 || lblock > last) return 0; since last = 4294967295 + 1 - 1 = 4294967295. This would later trigger the BUG_ON(es->es_lblk + es->es_len < es->es_lblk) in ext4_es_end(). We can simplify it by removing the - 1 altogether and changing the test to use lblock + len <= lblock, since now if len = 0, then lblock + 0 == lblock and it fails, and if len > 0 then lblock + len > lblock in order to pass (i.e. it doesn't overflow).

commit 15e4292a upstream. This patch fixes an issue that the CFIFOSEL register value is possible to be changed by usbhsg_ep_enable() wrongly. And then, a data transfer using CFIFO may not work correctly. For example: # modprobe g_multi file=usb-storage.bin # ifconfig usb0 192.168.1.1 up (During the USB host is sending file to the mass storage) # ifconfig usb0 down In this case, since the u_ether.c may call usb_ep_enable() in eth_stop(), if the renesas_usbhs driver is also using CFIFO for mass storage, the mass storage may not work correctly. So, this patch adds usbhs_lock() and usbhs_unlock() calling in usbhsg_ep_enable() to protect CFIFOSEL register. This is because: - CFIFOSEL.CURPIPE = 0 is also needed for the pipe configuration - The CFIFOSEL (fifo->sel) is already protected by usbhs_lock() Fixes: 97664a20 ("usb: renesas_usbhs: shrink spin lock area") Signed-off-by:

commit 926b7b51 upstream. On non-DeviceTree platforms, the index of serial device is a static variable incremented on each probe. It is incremented even if deferred probe happens when getting the clock in s3c24xx_serial_init_port(). This index is used for referencing elements of statically allocated s3c24xx_serial_ports array. In case of re-probe, the index will point outside of this array leading to memory corruption. Increment the index only on successful probe. Reported-by:

On next re-probe, the function s3c24xx_serial_init_port() will exit early with success because of configured port->mapbase and driver will use old values, including the ERR_PTR as clock. Fix this by cleaning the port->mapbase on error path so each re-probe will initialize all of the port settings.

commit c5379ba8 upstream. Until now, our understanding for HW I/O coherency to work on the Cortex-A9 based Marvell SoC was that only the PCIe regions should be mapped strongly-ordered. However, we were still encountering some deadlocks, especially when testing the CESA crypto engine. After checking with the HW designers, it was concluded that all the MMIO registers should be mapped as strongly ordered for the HW I/O coherency mechanism to work properly. This fixes some easy to reproduce deadlocks with the CESA crypto engine driver (dmcrypt on a sufficiently large disk partition). Tested-by:

commit 3d89e547 upstream. Commit: e9532e69 ("sched/cputime: Fix steal time accounting vs. CPU hotplug") ... set rq->prev_* to 0 after a CPU hotplug comes back, in order to fix the case where (after CPU hotplug) steal time is smaller than rq->prev_steal_time. However, this should never happen. Steal time was only smaller because of the KVM-specific bug fixed by the previous patch. Worse, the previous patch triggers a bug on CPU hot-unplug/plug operation: because rq->prev_steal_time is cleared, all of the CPU's past steal time will be accounted again on hot-plug. Since the root cause has been fixed, we can just revert commit e9532e69. Signed-off-by:

commit 29debab0 upstream. The devices don't have a name set, so makes dev_name() returns NULL which makes harder to identify the devices that are causing issues, for example: WARNING: CPU: 2 PID: 616 at drivers/base/core.c:251 device_release+0x8c/0x90 Device '(null)' does not have a release() function, it is broken and must be fixed. And after setting the device name: WARNING: CPU: 0 PID: 591 at drivers/base/core.c:251 device_release+0x8c/0x90 Device 's5p-mfc-l' does not have a release() function, it is broken and must be fixed.
