commit 5f0ee9d1 upstream. Make the check to skip the rate check more lax, so that it applies to all hw_version 4 models. This fixes the touchpad not being detected properly on Asus PU551LA laptops. Reported-and-tested-by:

commit f18c34e4 upstream. If the specified maximum length of the string is a multiple of unsigned long, we would load one long behind the specified maximum. If that happens to be in a next page, we can hit a page fault although we were not expected to. Fix the off-by-one bug in the test whether we are at the end of the specified range. Signed-off-by:

commit 425be567 upstream. The early_idt_handlers asm code generates an array of entry points spaced nine bytes apart. It's not really clear from that code or from the places that reference it what's going on, and the code only works in the first place because GAS never generates two-byte JMP instructions when jumping to global labels. Clean up the code to generate the correct array stride (member size) explicitly. This should be considerably more robust against screw-ups, as GAS will warn if a .fill directive has a negative count. Using '. =' to advance would have been even more robust (it would generate an actual error if it tried to move backwards), but it would pad with nulls, confusing anyone who tries to disassemble the code. The new scheme should be much clearer to future readers. While we're at it, improve the comments and rename the array and common code. Binutils may start relaxing jumps to non-weak labels. If so, this change will fix our build, and we may need to backport this change.

commit e058c945 upstream. According to the HSW b-spec we need to try clock divisors of 63 and 72, each 3 or more times, when attempting DP AUX channel communication on a server chipset. This actually wasn't happening due to a short-circuit that only checked the DP_AUX_CH_CTL_DONE bit in status rather than checking that the operation was done and that DP_AUX_CH_CTL_TIME_OUT_ERROR was not set. [v2] Implemented alternate solution suggested by Jani Nikula. Signed-off-by:

commit b1bb5b49 upstream. Using signed integers, the subtraction between required_size and offset could wind up being negative, resulting in a memcpy into a heap buffer with a negative length, resulting in huge amounts of network-supplied data being copied into the heap, which could potentially lead to remote code execution..

commit d114b9fe upstream. Since elt->length is a u8, we can make this variable a u8. Then we can do proper bounds checking more easily.

commit 392bceed upstream. The driver configures the IDLE condition to interrupt the SDMA engine. Since the SDMA UART ROM script doesn't clear the IDLE bit itself, this caused repeated 1-byte DMA transfers, regardless of available data in the RX FIFO. Also, when returning due to the IDLE condition, the UART ROM script already increased its counter, causing residue to be off by one. This patch clears the IDLE condition to avoid repeated 1-byte DMA transfers and decreases count by when the DMA transfer was aborted due to the IDLE condition, fixing serial transfers using DMA on i.MX6Q.

commit d046ba26 upstream. The adis16448, unlike the other chips in this family, in addition to the hardware channels also sends out the DIAG_STAT register in burst mode before them. Handle that case by skipping over the first 2 bytes before we pass the received data to the buffer. Signed-off-by:

commit 9df56035 upstream. There are a few issues with the burst mode support. For one we don't setup the rx buffer, so the buffer will never be filled and all samples will read as the zero. Furthermore the tx buffer has the wrong type, which means the driver sends the wrong command and not the right data is returned. The final issue is that in burst mode all channels are transferred. Hence the length of the transfer length should be the number of hardware channels * 2 bytes. Currently the driver uses indio_dev->scan_bytes for this. But if the timestamp channel is enabled the scan_bytes will be larger than the burst length. Fix this by just calculating the burst length based on the number of hardware channels. Signed-off-by:

commit 161f873b upstream. We used to read file_handle twice. Once to get the amount of extra bytes, and once to fetch the entire structure. This may be problematic since we do size verifications only after the first read, so if the number of extra bytes changes in userspace between the first and second calls, we'll have an incoherent view of file_handle. Instead, read the constant size once, and copy that over to the final structure without having to re-read it again. Signed-off-by:

Fix this by moving ->attach() after setting dev->qdisc.

commit 3f7352bf upstream. x86 has variable length encoding. x86 JIT compiler is trying to pick the shortest encoding for given bpf instruction. While doing so the jump targets are changing, so JIT is doing multiple passes over the program. Typical program needs 3 passes. Some very short programs converge with 2 passes. Large programs may need 4 or 5. But specially crafted bpf programs may hit the pass limit and if the program converges on the last iteration the JIT compiler will be producing an image full of 'int 3' insns. Fix this corner case by doing final iteration over bpf program. Fixes: 0a14842f ("net: filter: Just In Time compiler for x86-64") Reported-by:

commit 6dfe5a04 upstream. xfs_attr_inactive() is supposed to clean up the attribute fork when the inode is being freed. While it removes attribute fork extents, it completely ignores attributes in local format, which means that there can still be active attributes on the inode after xfs_attr_inactive() has run. This leads to problems with concurrent inode writeback - the in-core inode attribute fork is removed without locking on the assumption that nothing will be attempting to access the attribute fork after a call to xfs_attr_inactive() because it isn't supposed to exist on disk any more. To fix this, make xfs_attr_inactive() completely remove all traces of the attribute fork from the inode, regardless of it's state. Further, also remove the in-core attribute fork structure safely so that there is nothing further that needs to be done by callers to clean up the attribute fork. This means we can remove the in-core and on-disk attribute forks atomically. Also, on error simply remove the in-memory attribute fork. There's nothing that can be done with it once we have failed to remove the on-disk attribute fork, so we may as well just blow it away here anyway. Reported-by:

commit 3530febb upstream. This reverts commit 7290006d. Through the regression report, it was revealed that the tpacpi_led_set() call to thinkpad_acpi helper doesn't only toggle the mute LED but actually mutes the sound. This is contradiction to the expectation, and rather confuses user. According to Henrique, it's not trivial to judge which TP model behaves "LED-only" and which model does whatever more intrusive, as Lenovo's implementations vary model by model. So, from the safety reason, we should revert the patch for now. Reported-by:
