[ Upstream commit e2ebfb21 ] Disabling interrupts for even a millisecond can cause problems for some devices. That can happen when sdhci changes clock frequency because it waits for the clock to become stable under a spin lock. The spin lock is not necessary here. Anything that is racing with changes to the I/O state is already broken. The mmc core already provides synchronization via "claiming" the host. Although the spin lock probably should be removed from the code paths that lead to this point, such a patch would touch too much code to be suitable for stable trees. Consequently, for this patch, just drop the spin lock while waiting. Signed-off-by:

[ Upstream commit 09424c50 ] The streaming_maxburst module parameter is 0 offset (0..15) so we must add 1 while using it for wBytesPerInterval calculation for the SuperSpeed companion descriptor. Without this host uvcvideo driver will always see the wrong wBytesPerInterval for SuperSpeed uvc gadget and may not find a suitable video interface endpoint. e.g. for streaming_maxburst = 0 case it will always fail as wBytePerInterval was evaluating to 0.

[ Upstream commit d82c0d12 ] Reorder the operations in decompress_kernel() to ensure initrd is moved to a safe location before the bss section is zeroed. During decompression bss can overlap with the initrd and this can corrupt the initrd contents depending on the size of the compressed kernel (which affects where the initrd is placed by the bootloader) and the size of the bss section of the decompressor. Also use the correct initrd size when checking for overlaps with parmblock. Fixes: 06c0dd72 ([S390] fix boot failures with compressed kernels) Cc: stable@vger.kernel.org Reviewed-by:

[ Upstream commit c520ff3d ] When snd_seq_pool_done() is called, it marks the closing flag to refuse the further cell insertions. But snd_seq_pool_done() itself doesn't clear the cells but just waits until all cells are cleared by the caller side. That is, it's racy, and this leads to the endless stall as syzkaller spotted. This patch addresses the racy by splitting the setup of pool->closing flag out of snd_seq_pool_done(), and calling it properly before snd_seq_pool_done().

[ Upstream commit 9702c67c ] The total ata xfer length may not be calculated properly, in that we do not use the proper method to get an sg element dma length. According to the code comment, sg_dma_len() should be used after dma_map_sg() is called. This issue was found by turning on the SMMUv3 in front of the hisi_sas controller in hip07. Multiple sg elements were being combined into a single element, but the original first element length was being use as the total xfer length.

[ Upstream commit 77dae613 ] While using emacs, cat or others' commands in konsole with recent kernels, I have met many times that CTRL-C freeze konsole. After konsole freeze I can't type anything, then I have to open a new one, it is very annoying. See bug report: https://bugs.kde.org/show_bug.cgi?id=175283 The platform in that bug report is Solaris, but now the pty in linux has the same problem or the same behavior as Solaris :) It has high possibility to trigger the problem follow steps below: Note: In my test, BigFile is a text file whose size is bigger than 1G 1:open konsole 1:cat BigFile 2:CTRL-C After some digging, I find out the reason is that commit 1d1d14da ("pty: Fix buffer flush deadlock") changes the behavior of pty_flush_buffer. Thread A Thread B -------- -------- 1:n_tty_poll return POLLIN 2:CTRL-C trigger pty_flush_buffer tty_buffer_flush n_tty_flush_buffer 3:attempt to check count of chars: ioctl(fd, TIOCINQ, &available) available is equal to 0 4:read(fd, buffer, avaiable) return 0 5:konsole close fd Yes, I know we could use the same patch included in the BUG report as a workaround for linux platform too. But I think the data in ldisc is belong to application of another side, we shouldn't clear it when we want to flush write buffer of this side in pty_flush_buffer. So I think it is better to disable ldisc flush in pty_flush_buffer, because its new hehavior bring no benefit except that it mess up the behavior between POLLIN, and TIOCINQ or FIONREAD. Also I find no flush_buffer function in others' tty driver has the same behavior as current pty_flush_buffer.

[ Upstream commit b9cf625d ] If ext4_convert_inline_data() was called on a directory with inline data, the filesystem was left in an inconsistent state (as considered by e2fsck) because the file size was not increased to cover the new block. This happened because the inode was not marked dirty after i_disksize was updated. Fix this by marking the inode dirty at the end of ext4_finish_convert_inline_dir(). This bug was probably not noticed before because most users mark the inode dirty afterwards for other reasons. But if userspace executed FS_IOC_SET_ENCRYPTION_POLICY with invalid parameters, as exercised by 'kvm-xfstests -c adv generic/396', then the inode was never marked dirty after updating i_disksize.

[ Upstream commit c236c8e9 ] While working on the futex code, I stumbled over this potential use-after-free scenario. Dmitry triggered it later with syzkaller. pi_mutex is a pointer into pi_state, which we drop the reference on in unqueue_me_pi(). So any access to that pointer after that is bad. Since other sites already do rt_mutex_unlock() with hb->lock held, see for example futex_lock_pi(), simply move the unlock before unqueue_me_pi(). Reported-by:

[ Upstream commit 60b89f19 ] On some DDR controllers, compatible with the sama5d3 one, the sequence to enter/exit/re-enter the self-refresh mode adds more constrains than what is currently written in the at91_idle driver. An actual access to the DDR chip is needed between exit and re-enter of this mode which is somehow difficult to implement. This sequence can completely hang the SoC. It is particularly experienced on parts which embed a L2 cache if the code run between IDLE calls fits in it... Moreover, as the intention is to enter and exit pretty rapidly from IDLE, the power-down mode is a good candidate. So now we use power-down instead of self-refresh. As we can simplify the code for sama5d3 compatible DDR controllers, we instantiate a new sama5d3_ddr_standby() function. Signed-off-by:

[ Upstream commit 3243367b ] Some USB 2.0 devices erroneously report millisecond values in bInterval. The generic config code manages to catch most of them, but in some cases it's not completely enough. The case at stake here is a USB 2.0 braille device, which wants to announce 10ms and thus sets bInterval to 10, but with the USB 2.0 computation that yields to 64ms. It happens that one can type fast enough to reach this interval and get the device buffers overflown, leading to problematic latencies. The generic config code does not catch this case because the 64ms is considered a sane enough value. This change thus adds a USB_QUIRK_LINEAR_FRAME_INTR_BINTERVAL quirk to mark devices which actually report milliseconds in bInterval, and marks Vario Ultra devices as needing it. Signed-off-by:

[ Upstream commit f259ca3e ] Make sure to check the number of endpoints to avoid dereferencing a NULL-pointer or accessing memory beyond the endpoint array should a malicious device lack the expected endpoints. Note that the endpoint access that causes the NULL-deref is currently only used for debugging purposes during probe so the oops only happens when dynamic debugging is enabled. This means the driver could be rewritten to continue to accept device with only two endpoints, should such devices exist.

[ Upstream commit 1dc56c52 ] Make sure to check the number of endpoints to avoid dereferencing a NULL-pointer should the probed device lack endpoints.

[ Upstream commit c0d0e351 ] Recently fallocate patch was merged and it uses MSDOS_I(inode)->mmu_private at fat_evict_inode(). However, fat_inode/fsinfo_inode that was introduced in past didn't initialize MSDOS_I(inode) properly. With those combinations, it became the cause of accessing random entry in FAT area.
