When the Android firmware enables the audio interfaces in accessory mode, it always declares in the control interface's baInterfaceNr array that interfaces 0 and 1 belong to the audio function. However, the accessory interface itself, if also enabled, already is at index 0 and shifts the actual audio interface numbers to 1 and 2, which prevents the PCM streaming interface from being seen by the host driver. To get the PCM interface interface to work, detect when the descriptors point to the (for this driver useless) accessory interface, and redirect to the correct one. Reported-by:

Thanks to commit f91eb62f ("init: scream bloody murder if interrupts are enabled too early"), "bloody murder" is now being screamed. With a MIPS OCTEON config, we use on_each_cpu() in our irq_chip.irq_bus_sync_unlock() function. This gets called in early as a result of the time_init() call. Because the !SMP version of on_each_cpu() unconditionally enables irqs, we get: WARNING: at init/main.c:560 start_kernel+0x250/0x410() Interrupts were enabled early CPU: 0 PID: 0 Comm: swapper Not tainted 3.10.0-rc5-Cavium-Octeon+ #801 Call Trace: show_stack+0x68/0x80 warn_slowpath_common+0x78/0xb0 warn_slowpath_fmt+0x38/0x48 start_kernel+0x250/0x410 Suggested fix: Do what we already do in the SMP version of on_each_cpu(), and use local_irq_save/local_irq_restore. Because we need a flags variable, make it a static inline to avoid name space issues. [ Change from v1: Convert on_each_cpu to a static inline function, add #include <linux/irqflags.h> to avoid build breakage on some files. on_each_cpu_mask() and on_each_cpu_cond() suffer the same problem as on_each_cpu(), but they are not causing !SMP bugs for me, so I will defer changing them to a less urgent patch. ] Signed-off-by:

When replaying interrupts (as a result of the interrupt occurring while soft-disabled), in the case of the decrementer, we are exclusively testing for a pending timer target. However we also use decrementer interrupts to trigger the new "irq_work", which in this case would be missed. This change the logic to force a replay in both cases of a timer boundary reached and a decrementer interrupt having actually occurred while disabled. The former test is still useful to catch cases where a CPU having been hard-disabled for a long time completely misses the interrupt due to a decrementer rollover.

Normally, the kernel emulates a few instructions that are unimplemented on some processors (e.g. the old dcba instruction), or privileged (e.g. mfpvr). The emulation of unimplemented instructions is currently not working on the PowerNV platform. The reason is that on these machines, unimplemented and illegal instructions cause a hypervisor emulation assist interrupt, rather than a program interrupt as on older CPUs. Our vector for the emulation assist interrupt just calls program_check_exception() directly, without setting the bit in SRR1 that indicates an illegal instruction interrupt. This fixes it by making the emulation assist interrupt set that bit before calling program_check_interrupt(). With this, old programs that use no-longer implemented instructions such as dcba now work again. CC: <stable@vger.kernel.org> Signed-off-by:

At that point the irq state is not consistent, ie. interrupts are hard disabled (by the exception entry), but the paca soft-enabled flag may be out of sync. This leads to the local_irq_restore() in trace_graph_entry() actually enabling interrupts, which we do not want. Because we have not yet reprogrammed the decrementer we immediately take another decrementer exception, and recurse. The fix is twofold. Firstly make sure we call DISABLE_INTS before calling RUNLATCH_ON. The badly named DISABLE_INTS actually reconciles the irq state in the paca with the hardware, making it safe again to call local_irq_save/restore(). Although that should be sufficient to fix the bug, we also mark the runlatch routines as notrace. They are called very early in the exception entry and we are asking for trouble tracing them. They are also fairly uninteresting and tracing them just adds unnecessary overhead.

exit_notify() does exit_task_namespaces() after forget_original_parent(). This was needed to ensure that ->nsproxy can't be cleared prematurely, an exiting child we are going to reparent can do do_notify_parent() and use the parent's (ours) pid_ns. However, after 32084504 "pidns: use task_active_pid_ns in do_notify_parent" ->nsproxy != NULL is no longer needed, we rely on task_active_pid_ns(). Move exit_task_namespaces() from exit_notify() to do_exit(), after exit_fs() and before exit_task_work(). This solves the problem reported by Andrey, free_ipc_ns()->shm_destroy() does fput() which needs task_work_add(). Note: this particular problem can be fixed if we change fput(), and that change makes sense anyway. But there is another reason to move the callsite. The original reason for exit_task_namespaces() from the middle of exit_notify() was subtle and it has already gone away, now this looks confusing. And this allows us do simplify exit_notify(), we can avoid unlock/lock(tasklist) and we can use ->exit_state instead of PF_EXITING in forget_original_parent(). Reported-by:

fput() assumes that it can't be called after exit_task_work() but this is not true, for example free_ipc_ns()->shm_destroy() can do this. In this case fput() silently leaks the file. Change it to fallback to delayed_fput_work if task_work_add() fails. The patch looks complicated but it is not, it changes the code from if (PF_KTHREAD) { schedule_work(...); return; } task_work_add(...) to if (!PF_KTHREAD) { if (!task_work_add(...)) return; /* fallback */ } schedule_work(...); As for shm_destroy() in particular, we could make another fix but I think this change makes sense anyway. There could be another similar user, it is not safe to assume that task_work_add() can't fail. Reported-by:

Unfortunately, we cannot guarantee that items logged multiple times and replayed by log recovery do not take objects back in time. When they are taken back in time, the go into an intermediate state which is corrupt, and hence verification that occurs on this intermediate state causes log recovery to abort with a corruption shutdown. Instead of causing a shutdown and unmountable filesystem, don't verify post-recovery items before they are written to disk. This is less than optimal, but there is no way to detect this issue for non-CRC filesystems If log recovery successfully completes, this will be undone and the object will be consistent by subsequent transactions that are replayed, so in most cases we don't need to take drastic action. For CRC enabled filesystems, leave the verifiers in place - we need to call them to recalculate the CRCs on the objects anyway. This recovery problem can be solved for such filesystems - we have a LSN stamped in all metadata at writeback time that we can to determine whether the item should be replayed or not. This is a separate piece of work, so is not addressed by this patch. Signed-off-by:

For CRC enabled filesystems, the BMBT is rooted in an inode, so it passes through a different code path on root splits than the freespace and inode btrees. This is much less traversed by xfstests than the other trees. When testing on a 1k block size filesystem, I've been seeing ASSERT failures in generic/234 like: XFS: Assertion failed: cur->bc_btnum != XFS_BTNUM_BMAP || cur->bc_private.b.allocated == 0, file: fs/xfs/xfs_btree.c, line: 317 which are generally preceded by a lblock check failure. I noticed this in the bmbt stats: $ pminfo -f xfs.btree.block_map xfs.btree.block_map.lookup value 39135 xfs.btree.block_map.compare value 268432 xfs.btree.block_map.insrec value 15786 xfs.btree.block_map.delrec value 13884 xfs.btree.block_map.newroot value 2 xfs.btree.block_map.killroot value 0 ..... Very little coverage of root splits and merges. Indeed, on a 4k filesystem, block_map.newroot and block_map.killroot are both zero. i.e. the code is not exercised at all, and it's the only generic btree infrastructure operation that is not exercised by a default run of xfstests. Turns out that on a 1k filesystem, generic/234 accounts for one of those two root splits, and that is somewhat of a smoking gun. In fact, it's the same problem we saw in the directory/attr code where headers are memcpy()d from one block to another without updating the self describing metadata. Simple fix - when copying the header out of the root block, make sure the block number is updated correctly. Signed-off-by:

Michael L. Semon has been testing CRC patches on a 32 bit system and been seeing assert failures in the directory code from xfs/080. Thanks to Michael's heroic efforts with printk debugging, we found that the problem was that the last free space being left in the directory structure was too small to fit a unused tag structure and it was being corrupted and attempting to log a region out of bounds. Hence the assert failure looked something like: ..... #5 calling xfs_dir2_data_log_unused() 36 32 #1 4092 4095 4096 #2 8182 8183 4096 XFS: Assertion failed: first <= last && last < BBTOB(bp->b_length), file: fs/xfs/xfs_trans_buf.c, line: 568 Where #1 showed the first region of the dup being logged (i.e. the last 4 bytes of a directory buffer) and #2 shows the corrupt values being calculated from the length of the dup entry which overflowed the size of the buffer. It turns out that the problem was not in the logging code, nor in the freespace handling code. It is an initial condition bug that only shows up on 32 bit systems. When a new buffer is initialised, where's the freespace that is set up: [ 172.316249] calling xfs_dir2_leaf_addname() from xfs_dir_createname() [ 172.316346] #9 calling xfs_dir2_data_log_unused() [ 172.316351] #1 calling xfs_trans_log_buf() 60 63 4096 [ 172.316353] #2 calling xfs_trans_log_buf() 4094 4095 4096 Note the offset of the first region being logged? It's 60 bytes into the buffer. Once I saw that, I pretty much knew that the bug was going to be caused by this. Essentially, all direct entries are rounded to 8 bytes in length, and all entries start with an 8 byte alignment. This means that we can decode inplace as variables are naturally aligned. With the directory data supposedly starting on a 8 byte boundary, and all entries padded to 8 bytes, the minimum freespace in a directory block is supposed to be 8 bytes, which is large enough to fit a unused data entry structure (6 bytes in size). The fact we only have 4 bytes of free space indicates a directory data block alignment problem. And what do you know - there's an implicit hole in the directory data block header for the CRC format, which means the header is 60 byte on 32 bit intel systems and 64 bytes on 64 bit systems. Needs padding. And while looking at the structures, I found the same problem in the attr leaf header. Fix them both. Note that this only affects 32 bit systems with CRCs enabled. Everything else is just fine. Note that CRC enabled filesystems created before this fix on such systems will not be readable with this fix applied. Reported-by:

We write the superblock every 30s or so which results in the verifier being called. Right now that results in this output every 30s: XFS (vda): Version 5 superblock detected. This kernel has EXPERIMENTAL support enabled! Use of these features in this kernel is at your own risk! And spamming the logs. We don't need to check for whether we support v5 superblocks or whether there are feature bits we don't support set as these are only relevant when we first mount the filesytem. i.e. on superblock read. Hence for the write verification we can just skip all the checks (and hence verbose output) altogether. Signed-off-by:

Flushing pending work items before resetting the device makes more sense than doing so afterwards. Some of them, like e.g. the NFC initialization one, find themselves with client IDs changed after the reset, eventually leading to trigger a client.c:mei_me_cl_by_id() warning after a few modprobe/rmmod cycles.

In commit 2f94aabd (refactor sctp_outq_teardown to insure proper re-initalization) we modified sctp_outq_teardown to use sctp_outq_init to fully re-initalize the outq structure. Steve West recently asked me why I removed the q->error = 0 initalization from sctp_outq_teardown. I did so because I was operating under the impression that sctp_outq_init would properly initalize that value for us, but it doesn't. sctp_outq_init operates under the assumption that the outq struct is all 0's (as it is when called from sctp_association_init), but using it in __sctp_outq_teardown violates that assumption. We should do a memset in sctp_outq_init to ensure that the entire structure is in a known state there instead. Signed-off-by:

Previously, the #line parsing regex ended with ({WS}+[0-9]+)?. The {WS} could match line-break characters. If the #line directive did not contain the optional flags field at the end, this could cause any integer data on the next line to be consumed as part of the #line directive parsing. This could cause syntax errors (i.e. #line parsing consuming the leading 0 from a hex literal 0x1234, leaving x1234 to be parsed as cell data, which is a syntax error), or invalid compilation results (i.e. simply consuming literal 1234 as part of the #line processing, thus removing it from the cell data). Fix this by replacing {WS} with [ \t] so that it can't match line-breaks. Convert all instances of {WS}, even though the other instances should be irrelevant for any well-formed #line directive. This is done for consistency and ultimate safety. [Cherry picked from DTC commit a1ee6f068e1c8dbc62873645037a353d7852d5cc] Reported-by:

This patch merely updates the generated dtc parser and lexer files to the output generated by Bison 2.5. The previous versions were generated from version 2.4.1. The only reason for this commit is to minimize the diff on the next commit which fixes a bug in the DTC #line directive parsing. Otherwise the Bison changes would be intermingled with the functional changes. Signed-off-by:
