commit 81d0fa4c upstream. All callers of trace_probe_primary_from_call() check the return value to be non NULL. However, the function returns list_first_entry(&tpe->probes, ...) which can never be NULL. Additionally, it does not check for the list being possibly empty, possibly causing a type confusion on empty lists. Use list_first_entry_or_null() which solves both problems.

commit e30fbc61 upstream. Modifiers are used to change the behavior of keys. For instance, they can grouped into buckets, converted to syscall names (from the syscall identifier), show task->comm of the current pid, be an array of longs that represent a stacktrace, and more. It was found that nothing stopped a value from taking a modifier. As values are simple counters. If this happened, it would call code that was not expecting a modifier and crash the kernel. This was fixed by having the ___create_val_field() function test if a modifier was present and fail if one was. This fixed the crash. Now there's a problem with variables. Variables are used to pass fields from one event to another. Variables are allowed to have some modifiers, as the processing may need to happen at the time of the event (like stacktraces and comm names of the current pid). The issue is that it too uses __create_val_field(). Now that fails on modifiers, variables can no longer use them (this is a regression). As not all modifiers are for variables, have them use a separate check.

commit 632478a0 upstream. While testing rtla timerlat auto analysis, I reach a condition where the interface was not receiving tracing data. I was able to manually reproduce the problem with these steps: # echo 0 > tracing_on # disable trace # echo 1 > osnoise/stop_tracing_us # stop trace if timerlat irq > 1 us # echo timerlat > current_tracer # enable timerlat tracer # sleep 1 # wait... that is the time when rtla # apply configs like prio or cgroup # echo 1 > tracing_on # start tracing # cat trace # tracer: timerlat # # _-----=> irqs-off # / _----=> need-resched # | / _---=> hardirq/softirq # || / _--=> preempt-depth # ||| / _-=> migrate-disable # |||| / delay # ||||| ACTIVATION # TASK-PID CPU# ||||| TIMESTAMP ID CONTEXT LATENCY # | | | ||||| | | | | NOTHING! Then, trying to enable tracing again with echo 1 > tracing_on resulted in no change: the trace was still not tracing. This problem happens because the timerlat IRQ hits the stop tracing condition while tracing is off, and do not wake up the timerlat thread, so the timerlat threads are kept sleeping forever, resulting in no trace, even after re-enabling the tracer. Avoid this condition by always waking up the threads, even after stopping tracing, allowing the tracer to return to its normal operating after a new tracing on.

Removed the grouped target introduced in 4ce1f694 ("selinux: ensure av_permissions.h is built when needed") as well as the multiple header file targets in the make rule. This effectively reverts the problem commit. We will revisit this change when make >= 4.3 is required by the rest of the kernel.

commit 9a7e8ec0 upstream. For RISC-V, when tracing with tracepoint events, the IP and status are set to 0, preventing the perf code parsing the callchain and resolving the symbols correctly. ./ply 'tracepoint:kmem/kmem_cache_alloc { @[stack]=count(); }' @: { <STACKID4294967282> }: 1 The fix is to implement perf_arch_fetch_caller_regs for riscv, which fills several necessary registers used for callchain unwinding, including epc, sp, s0 and status.

[ Upstream commit 45c2f368 ] When I implemented the storage layer bio splitting, I was under the assumption that we'll never split metadata bios. But Qu reminded me that this can actually happen with very old file systems with unaligned metadata chunks and RAID0. I still haven't seen such a case in practice, but we better handled this case, especially as it is fairly easily to do not calling the ->end_іo method directly in btrfs_end_io_work, and using the proper btrfs_orig_bbio_end_io helper instead. In addition to the old file system with unaligned metadata chunks case documented in the commit log, the combination of the new scrub code with Johannes pending raid-stripe-tree also triggers this case. We spent some time debugging it and found that this patch solves the problem.

Domain flush takes gather bounds (end-start) as size param. However, gather->end is defined as the last inclusive address (start + size - 1). This leads to an off by 1 error.

commit 47fe1c30 upstream. The scsi driver function sd_read_block_characteristics() always calls disk_set_zoned() to a disk zoned model correctly, in case the device model changed. This is done even for regular disks to set the zoned model to BLK_ZONED_NONE and free any zone related resources if the drive previously was zoned. This behavior significantly impact the time it takes to revalidate disks on a large system as the call to disk_clear_zone_settings() done from disk_set_zoned() for the BLK_ZONED_NONE case results in the device request queued to be frozen, even if there are no zone resources to free. Avoid this overhead for non-zoned devices by not calling disk_clear_zone_settings() in disk_set_zoned() if the device model was already set to BLK_ZONED_NONE, which is always the case for regular devices.

commit 2474e054 upstream. LPUART IP now has two known bugs, one is that CTS has higher priority than the break signal, which causes the break signal sending through UARTCTRL_SBK may impacted by the CTS input if the HW flow control is enabled. It exists on all platforms we support in this driver. So we add a workaround patch for this issue: commit c4c81db5 ("tty: serial: fsl_lpuart: disable the CTS when send break signal"). Another IP bug is i.MX8QM LPUART may have an additional break character being sent after SBK was cleared. It may need to add some delay between clearing SBK and re-enabling CTS to ensure that the SBK latch are completely cleared. But we found that during the delay period before CTS is enabled, there is still a risk that Bluetooth data in TX FIFO may be sent out during this period because of break off and CTS disabled(even if BT sets CTS line deasserted, data is still sent to BT). Due to this risk, we have to drop the CTS-disabling workaround for SBK bugs, use TXINV seems to be a better way to replace SBK feature and avoid above risk. Also need to disable the transmitter to prevent any data from being sent out during break, then invert the TX line to send break. Then disable the TXINV when turn off break and re-enable transmitter.

All tools and software that talks to the driver then has to know different ways to interpret the data depending on the asic.

commit 7f875850 upstream. For devices not attached to a port multiplier and managed directly by libata, the device number passed to ata_find_dev() must always be lower than the maximum number of devices returned by ata_link_max_devices(). That is 1 for SATA devices or 2 for an IDE link with master+slave devices. This device number is the SCSI device ID which matches these constraints as the IDs are generated per port and so never exceed the maximum number of devices for the link being used. However, for libsas managed devices, SCSI device IDs are assigned per struct scsi_host, leading to device IDs for SATA devices that can be well in excess of libata per-link maximum number of devices. This results in ata_find_dev() to always return NULL for libsas managed devices except for the first device of the target scsi_host with ID (device number) equal to 0. This issue is visible by executing the hdparm utility, which fails. E.g.: hdparm -i /dev/sdX /dev/sdX: HDIO_GET_IDENTITY failed: No message of desired type Fix this by rewriting ata_find_dev() to ignore the device number for non-PMP attached devices with a link with at most 1 device, that is SATA devices. For these, the device number 0 is always used to return the correct pointer to the struct ata_device of the port link. This change excludes IDE master/slave setups (maximum number of devices per link is 2) and port-multiplier attached devices. Also, to be consistant with the fact that SCSI device IDs and channel numbers used as device numbers are both unsigned int, change the devno argument of ata_find_dev() to unsigned int. Reported-by:

commit 46248400 upstream. The channel's rpmsg object allows new invocations to be made. After old invocations are already interrupted, the driver shouldn't try to invoke anymore. Invalidating the rpmsg at the end of the driver removal function makes it easy to cause a race condition in userspace. Even closing a file descriptor before the driver finishes its cleanup can cause an invocation via fastrpc_release_current_dsp_process() and subsequent timeout. Invalidate the channel before the invocations are interrupted to make sure that no invocations can be created to hang after the device closes.

commit b6a06285 upstream. The return value is initialized as -1, or -EPERM. The completion of an invocation implies that the return value is set appropriately, but "Permission denied" does not accurately describe the outcome of the invocation. Set the invocation's return value to a more appropriate "Broken pipe", as the cleanup breaks the driver's connection with rpmsg.

commit 3c7d0079 upstream. The userspace map request for remote heap allocates CMA memory. The ownership of this memory needs to be reassigned to proper owners to allow access from the protection domain running on DSP. This reassigning of ownership is not correct if done for any other supported flags. When any other flag is requested from userspace, fastrpc is trying to reassign the ownership of memory and this reassignment is getting skipped for remote heap request which is incorrect. Add proper flag check to reassign the memory only if remote heap is requested.

commit efb6b535 upstream. While exercising the unbind path, with the current implementation the functionfs_unbind would be calling which waits for the ffs->mutex to be available, however within the same time ffs_ep0_read is invoked & if no setup packets are pending, it will invoke function wait_event_interruptible_exclusive_locked_irq which by definition waits for the ev.count to be increased inside the same mutex for which functionfs_unbind is waiting. This creates deadlock situation because the functionfs_unbind won't get the lock until ev.count is increased which can only happen if the caller ffs_func_unbind can proceed further. Following is the illustration: CPU1 CPU2 ffs_func_unbind() ffs_ep0_read() mutex_lock(ffs->mutex) wait_event(ffs->ev.count) functionfs_unbind() mutex_lock(ffs->mutex) mutex_unlock(ffs->mutex) ffs_event_add() <deadlock> Fix this by moving the event unbind before functionfs_unbind to ensure the ev.count is incrased properly.

The root cause of this performance drop was found to be data corruption happening at 4K borders in some Ethernet packets, leading to TCP checksum errors. This corruption occurs from the position (4K - (address & 0x7F)) to 4K. The u_ether function's allocation of skb_buff reserves 64B, meaning all RX addresses resemble 0xXXXX0040.
