commit f17bc3f4 upstream. Since (min_row_time - crop->width) can be negative, we have to do a signed comparison here. Otherwise max_t casts the negative value to unsigned int and sets min_hblank to that invalid value. Signed-off-by:

commit 64ea37bb upstream. It seems that there's a bug at au0828 hardware/firmware related to alternate setting: when the device is already at alt 5, a further call causes the URBs to receive -ESHUTDOWN. I found two different encarnations of this issue: 1) at qv4l2, it fails the second time we try to open the video screen; 2) at xawtv, when audio underrun occurs, with is very frequent, at least on my test machine. The fix is simple: just check if alt=5 before calling set_usb_interface(). Signed-off-by:

commit 4c07e328 upstream. The programmed frequency on xc4000 is not the middle frequency, but the initial frequency on the bandwidth range. However, the DVB API works with the middle frequency. This works fine on set_frontend, as the device calculates the needed offset. However, at get_frequency(), the returned value is the initial frequency. That's generally not a big problem on most drivers, however, starting with changeset 6fe1099c, the frequency drift is taken into account at dib7000p driver. This broke support for PCTV 340e, with uses dib7000p demod and xc4000 tuner. Signed-off-by:

commit 01777836 upstream. If do_journal_release() races with do_journal_end() which requeues delayed works for transaction flushing, we can leave work items for flushing outstanding transactions queued while freeing them. That results in use after free and possible crash in run_timers_softirq(). Fix the problem by not requeueing works if superblock is being shut down (MS_ACTIVE not set) and using cancel_delayed_work_sync() in do_journal_release(). Signed-off-by:

commit 27d0e5bc upstream. Commits f1f007c3 (reiserfs: balance_leaf refactor, pull out balance_leaf_insert_left) and cf22df18 (reiserfs: balance_leaf refactor, pull out balance_leaf_paste_left) missed that the `body' pointer was getting repositioned. Subsequent users of the pointer would expect it to be repositioned, and as a result, parts of the tree would get overwritten. The most common observed corruption is indirect block pointers being overwritten. Since the body value isn't actually used anymore in the called routines, we can pass back the offset it should be shifted. We constify the body and ih pointers in the balance_leaf as a mostly-free preventative measure. Reported-and-tested-by:

commit 3c45ddf8 upstream. The current code always selects XPRT_TRANSPORT_BC_TCP for the back channel, even when the forward channel was not TCP (eg, RDMA). When a 4.1 mount is attempted with RDMA, the server panics in the TCP BC code when trying to send CB_NULL. Instead, construct the transport protocol number from the forward channel transport or'd with XPRT_TRANSPORT_BC. Transports that do not support bi-directional RPC will not have registered a "BC" transport, causing create_backchannel_client() to fail immediately.

commit dd5f5006 upstream. The commit [5ee0f803: usbcore: don't log on consecutive debounce failures of the same port] added the check of the reliable port, but it also replaced the device argument to dev_err() wrongly, which leads to a NULL dereference. This patch restores the right device, port_dev->dev. Also, since dev_err() itself shows the port number, reduce the port number shown in the error message, essentially reverting to the state before the commit 5ee0f803.

This is due to an unchecked memcpy into a fixed size buffer (of 64 bytes). On EHCI and XHCI busses it's possible to craft responses greater than 64 bytes leading a buffer overflow. Signed-off-by:

commit cc824534 upstream. Looks like MUSB cable removal can cause wake-up interrupts to stop working for device tree based booting at least for UART3 even as nothing is dynamically remuxed. This can be fixed by calling reconfigure_io_chain() for device tree based booting in hwmod code. Note that we already do that for legacy booting if the legacy mux is configured. My guess is that this is related to UART3 and MUSB ULPI hsusb0_data0 and hsusb0_data1 support for Carkit mode that somehow affect the configured IO chain for UART3 and require rearming the wake-up interrupts. In general, for device tree based booting, pinctrl-single calls the rearm hook that in turn calls reconfigure_io_chain so calling reconfigure_io_chain should not be needed from the hwmod code for other events. So let's limit the hwmod rearming of iochain only to HWMOD_FORCE_MSTANDBY where MUSB is currently the only user of it. If we see other devices needing similar changes we can add more checks for it.

commit 365038d8 upstream. When we manually need to move the TR dequeue pointer we need to set the correct cycle bit as well. Previously we used the trb pointer from the last event received as a base, but this was changed in commit 1f81b6d2 ("usb: xhci: Prefer endpoint context dequeue pointer") to use the dequeue pointer from the endpoint context instead It turns out some Asmedia controllers advance the dequeue pointer stored in the endpoint context past the event triggering TRB, and this messed up the way the cycle bit was calculated. Instead of adding a quirk or complicating the already hard to follow cycle bit code, the whole cycle bit calculation is now simplified and adapted to handle event and endpoint context dequeue pointer differences.

commit ec0a38bf upstream. Fix two reported bugs, caused by et131x_adapter->phydev->addr being accessed before it is initialised, by: - letting et131x_mii_write() take a phydev address, instead of using the one stored in adapter by default. This is so et131x_mdio_write() can use it's own addr value. - removing implementation of et131x_mdio_reset(), as it's not needed. - moving a call to et131x_disable_phy_coma() in et131x_pci_setup(), which uses phydev->addr, until after the mdiobus has been registered.

commit db9ee220 upstream. It turns out that there are some serious problems with the on-disk format of journal checksum v2. The foremost is that the function to calculate descriptor tag size returns sizes that are too big. This causes alignment issues on some architectures and is compounded by the fact that some parts of jbd2 use the structure size (incorrectly) to determine the presence of a 64bit journal instead of checking the feature flags. Therefore, introduce journal checksum v3, which enlarges the descriptor block tag format to allow for full 32-bit checksums of journal blocks, fix the journal tag function to return the correct sizes, and fix the jbd2 recovery code to use feature flags to determine 64bitness. Add a few function helpers so we don't have to open-code quite so many pieces. Switching to a 16-byte block size was found to increase journal size overhead by a maximum of 0.1%, to convert a 32-bit journal with no checksumming to a 32-bit journal with checksum v3 enabled.

commit d80d448c upstream. When performing a same-directory rename, it's possible that adding or setting the new directory entry will cause the directory to overflow the inline data area, which causes the directory to be converted to an extent-based directory. Under this circumstance it is necessary to re-read the directory when deleting the old dirent because the "old directory" context still points to i_block in the inode table, which is now an extent tree root! The delete fails with an FS error, and the subsequent fsck complains about incorrect link counts and hardlinked directories. Test case (originally found with flat_dir_test in the metadata_csum test program): # mkfs.ext4 -O inline_data /dev/sda # mount /dev/sda /mnt # mkdir /mnt/x # touch /mnt/x/changelog.gz /mnt/x/copyright /mnt/x/README.Debian # sync # for i in /mnt/x/*; do mv $i $i.longer; done # ls -la /mnt/x/ total 0 -rw-r--r-- 1 root root 0 Aug 25 12:03 changelog.gz.longer -rw-r--r-- 1 root root 0 Aug 25 12:03 copyright -rw-r--r-- 1 root root 0 Aug 25 12:03 copyright.longer -rw-r--r-- 1 root root 0 Aug 25 12:03 README.Debian.longer (Hey!
