commit 09d8091c upstream. Commit a8227415 "tracing: Protect ftrace_trace_arrays list in trace_events.c" added taking the trace_types_lock mutex in trace_events.c as there were several locations that needed it for protection. Unfortunately, it also encapsulated a call to tracing_reset_all_online_cpus() which also takes the trace_types_lock, causing a deadlock. This happens when a module has tracepoints and has been traced. When the module is removed, the trace events module notifier will grab the trace_types_lock, do a bunch of clean ups, and also clears the buffer by calling tracing_reset_all_online_cpus. This doesn't happen often which explains why it wasn't caught right away. Commit a8227415 was marked for stable, which means this must be sent to stable too.

commit e70e78e3 upstream. tracing_buffers_open() does trace_array_get() and then it wrongly inrcements tr->ref again under trace_types_lock. This means that every caller leaks trace_array: # cd /sys/kernel/debug/tracing/ # mkdir instances/X # true < instances/X/per_cpu/cpu0/trace_pipe_raw # rmdir instances/X rmdir: failed to remove `instances/X': Device or resource busy Link: http://lkml.kernel.org/r/20130719153644.GA18899@redhat.comSigned-off-by:

commit 609e85a7 upstream. Remove debugfs directories for tracing instances during creation if an error occurs causing the trace_array for that instance to not be added to ftrace_trace_arrays. If the directory continues to exist after the error, it cannot be removed because the respective trace_array is not in ftrace_trace_arrays.

commit 085b513f upstream. sd_prep_fn will allocate a larger CDB for the command via mempool_alloc for devices using DIF type 2 protection. This CDB was being freed in sd_done, which results in a kernel crash if the command is retried due to a UNIT ATTENTION. This change moves the code to free the larger CDB into sd_unprep_fn instead, which is invoked after the request is complete. It is no longer necessary to call scsi_print_command separately for this case as the ->cmnd will no longer be NULL in the normal code path. Also removed conditional test for DIF type 2 when freeing the larger CDB because the protection_type could have been changed via sysfs while the command was executing. Signed-off-by:

commit 96f15f29 upstream. This commit fixes a race condition in the isci driver abort task and SSP device task management path. The race is caused when an I/O termination in the SCU hardware is necessary because of an SSP target timeout condition, and the check of the I/O end state races against the HW-termination-driven end state. The failure of the race meant that no TMF was sent to the device to clean-up the pending I/O. Signed-off-by:

commit faefd550 upstream. When CONFIG_ARM_APPENDED_DTB is selected, if the bootloader provides an ATAG_MEM it replaces the memory size and the memory address in the memory node of the device tree. In the case of a system which can handle more than 4GB, the memory node cell size is 4: each data (memory size and memory address) are 64 bits and then use 2 cells. The current code in atags_to_fdt.c made the assumption of a cell size of 2 (one cell for the memory size and one cell for the memory address), this leads to an improper write of the data and ends with a boot hang. This patch writes the memory size and the memory address on the memory node in the device tree depending of the size of the memory node (32 bits or 64 bits). It has been tested in the 2 cases: - with a dtb using skeleton.dtsi - and with a dtb using skeleton64.dtsi Signed-off-by:

commit 0699a73a upstream. Commit 18d62711 (firewire: prevent dropping of completed iso packet header data) was intended to be an obvious bug fix, but libdc1394 and FlyCap2 depend on the old behaviour by ignoring all returned information and thus not noticing that not all packets have been received yet. The result was that the video frame buffers would be saved before they contained the correct data. Reintroduce the old behaviour for old clients. Tested-by:

commit b2cb9649 upstream. This patch addresses a bug where RDMA_CM_EVENT_DISCONNECTED may occur before the connection shutdown has been completed by rx/tx threads, that causes isert_free_conn() to wait indefinately on ->conn_wait. This patch allows isert_disconnect_work code to invoke rdma_disconnect when isert_disconnect_work() process context is started by client session reset before isert_free_conn() code has been reached. It also adds isert_conn->conn_mutex protection for ->state within isert_disconnect_work(), isert_cq_comp_err() and isert_free_conn() code, along with isert_check_state() for wait_event usage.

commit f3e351ee upstream. The quirk for Dell laptops with STAC9228 overrides the pin default config of NID 0x0f to the value with AC_DEFCFG_MISC_NO_PRESENCE bit on. I'm not quite sure why this was done so, but can guess that this was introduced for avoiding this to be muted by another headphone plug. Now, after transition to the generic parser, this workaround rather causes a problem (notably as unexpected speaker mutes) because the pin is seen as if it's always plugged in. Since the generic parser can handle multiple headphone plugging gracefully, we can get rid of this override now. Reported-and-tested-by:

commit 5ec2481b upstream. smp_call_function_* must not be called from softirq context. But clock_was_set() which calls on_each_cpu() is called from softirq context to implement a delayed clock_was_set() for the timer interrupt handler. Though that almost never gets invoked. A recent change in the resume code uses the softirq based delayed clock_was_set to support Xens resume mechanism. linux-next contains a new warning which warns if smp_call_function_* is called from softirq context which gets triggered by that Xen change. Fix this by moving the delayed clock_was_set() call to a work context. Reported-and-tested-by:

commit 1c327d96 upstream. In nlmsvc_retry_blocked, the check that the list is non-empty and acquiring the pointer of the first entry is unprotected by any lock. This allows a rare race condition when there is only one entry on the list. A function such as nlmsvc_grant_callback() can be called, which will temporarily remove the entry from the list. Between the list_empty() and list_entry(),the list may become empty, causing an invalid pointer to be used as an nlm_block, leading to a possible crash. This patch adds the nlm_block_lock around these calls to prevent concurrent use of the nlm_blocked list. This was a regression introduced by f904be9c "lockd: Mostly remove BKL from the server".

commit 414abbd2 upstream. In dvb_ringbuffer lock-less synchronizationof reader and writer threads is done with separateread and write pointers. Sincedvb_ringbuffer_flush() modifies the read pointer, this function must not be called from the writer thread. This patch removes the dvb_ringbuffer_flush() calls in the dmxdev ringbuffer write functions, this fixes Oopses "Unable to handle kernel paging request" I could observe for the call chaindvb_demux_read ->dvb_dmxdev_buffer_read -> dvb_ringbuffer_read_user -> __copy_to_user (the reader side of the ringbuffer). The flush calls at the write side are not necessary anyway since ringbuffer_flush is also called in dvb_dmxdev_buffer_read() when an error condition is set in the ringbuffer. This patch should also be applied to stable kernels. Signed-off-by:

commit e5248a11 upstream. Prevent automatic system suspend from happening during system shutdown by making try_to_suspend() check system_state and return immediately if it is not SYSTEM_RUNNING. This prevents the following breakage from happening (scenario from Zhang Yanmin): Kernel starts shutdown and calls all device driver's shutdown callback. When a driver's shutdown is called, the last wakelock is released and suspend-to-ram starts. However, as some driver's shut down callbacks already shut down devices and disabled runtime pm, the suspend-to-ram calls driver's suspend callback without noticing that device is already off and causes crash.

Rob thought the code would re-use the static mapping, but that turns out to not be the case and instead hits the BUG further down.

commit d817468c upstream. This patch restores serial port operation which has been broken since commit 60e93575 ("serial: samsung: enable clock before clearing pending interrupts during init") That commit only uncovered the real issue which was missing clkdev entries for the "uart" clocks on S3C2440. It went unnoticed so far because return value of clk API calls were not being checked at all in the samsung serial port driver. This patch should be backported to at least 3.10 stable kernel, since the serial port has not been working on s3c2440 since 3.10-rc5. Signed-off-by:
