2012-09-26new helper: __alloc_fd()Al Viro
Essentially, alloc_fd() in a files_struct we own a reference to. Most of the time wanting to use it is a sign of lousy API design (such as android/binder). It's *not* a general-purpose interface; better that than open-coding its guts, but again, playing with other process' descriptor table is a sign of bad design.

2012-09-26fanotify: sanitize failure exits in copy_event_to_user()Al Viro
* do copy_to_user() before prepare_for_access_response(); that kills the need in remove_access_response(). * don't do fd_install() until we are past the last possible failure exit. Don't use sys_close() on cleanup side - just put_unused_fd() and fput(). Less racy that way... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-09-26autofs4: don't open-code fd_install()Al Viro
The only difference between autofs_dev_ioctl_fd_install() and fd_install() is __set_close_on_exec() done by the latter. Just use get_unused_fd_flags(O_CLOEXEC) to allocate the descriptor and be done with that... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-09-26unexport sock_map_fd(), switch to sock_alloc_file()Al Viro
Both modular callers of sock_map_fd() had been buggy; sctp one leaks descriptor and file if copy_to_user() fails, 9p one shouldn't be exposing file in the descriptor table at all. Switch both to sock_alloc_file(), export it, unexport sock_map_fd() and make it static. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-09-26perf trace: New toolArnaldo Carvalho de Melo
Initially should look loosely like the venerable 'strace' tool, but using the infrastructure in the perf tools to allow tracing extra targets: [acme@sandy linux]$ perf trace --hell Error: unknown option `hell' usage: perf trace <PID> -p, --pid <pid> trace events on existing process id --tid <tid> trace events on existing thread id --all-cpus system-wide collection from all CPUs --cpu <cpu> list of cpus to monitor --no-inherit child tasks do not inherit counters --mmap-pages <n> number of mmap data pages --uid <user> user to profile [acme@sandy linux]$ Those should have the same semantics as when using with 'perf record'. It gets stuck sometimes, but hey, it works sometimes too! In time it should support perf.data based workloads, i.e. it should have a: -o filename Command line option that will produce a perf.data file that can then be used with 'perf trace' or any of the other perf tools (script, report, etc). It will also eventually have the set of functionalities described in the previous 'trace' prototype by Thomas Gleixner: "Announcing a new utility: 'trace'" http://lwn.net/Articles/415728/ Also planned is to have some of the features suggested in the comments of that LWN article.

2012-09-27drm/nvc0/fifo: ignore bits in PFIFO_INTR that aren't set in PFIFO_INTR_ENBen Skeggs
PFIFO_INTR = 0x40000000 appears to be a normal case on nvc0/nve0 PFIFO, the binary driver appears to completely ignore it in its PFIFO interrupt handler and even masks off the bit (as we do) in PFIFO_INTR_EN at init time. The bits still light up in the hardware sometimes though, so lets just ignore any bits we haven't explicitely requested. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-09-26dm thin: fix discard support for data devicesMike Snitzer
The discard limits that get established for a thin-pool or thin device may be incompatible with the pool's data device. Avoid this by checking the discard limits of the pool's data device. If an incompatibility is found then the pool's 'discard passdown' feature is disabled. Change thin_io_hints to ensure that a thin device always uses the same queue limits as its pool device. Introduce requested_pf to track whether or not the table line originally contained the no_discard_passdown flag and use this directly for table output. We prepare the correct setting for discard_passdown directly in bind_control_target (called from pool_io_hints) and store it in adjusted_pf rather than waiting until we have access to pool->pf in pool_preresume.

2012-09-26dm: retain table limits when swapping to new table with no devicesMike Snitzer
Add a safety net that will re-use the DM device's existing limits in the event that DM device has a temporary table that doesn't have any component devices. This is to reduce the chance that requests not respecting the hardware limits will reach the device. DM recalculates queue limits based only on devices which currently exist in the table. This creates a problem in the event all devices are temporarily removed such as all paths being lost in multipath. DM will reset the limits to the maximum permissible, which can then assemble requests which exceed the limits of the paths when the paths are restored. The request will fail the blk_rq_check_limits() test when sent to a path with lower limits, and will be retried without end by multipath. This became a much bigger issue after v3.6 commit fe86cdcef ("block: do not artificially constrain max_sectors for stacking drivers").

2012-09-26dm table: clear add_random unless all devices have it setMilan Broz
Always clear QUEUE_FLAG_ADD_RANDOM if any underlying device does not have it set. Otherwise devices with predictable characteristics may contribute entropy. QUEUE_FLAG_ADD_RANDOM specifies whether or not queue IO timings contribute to the random pool. For bio-based targets this flag is always 0 because such devices have no real queue. For request-based devices this flag was always set to 1 by default. Now set it according to the flags on underlying devices. If there is at least one device which should not contribute, set the flag to zero: If a device, such as fast SSD storage, is not suitable for supplying entropy, a request-based queue stacked over it will not be either. Because the checking logic is exactly same as for the rotational flag, share the iteration function with device_is_nonrot().

2012-09-26dm: handle requests beyond end of device instead of using BUG_ONMike Snitzer
The access beyond the end of device BUG_ON that was introduced to dm_request_fn via commit 29e4013de7ad950280e4b2208 ("dm: implement REQ_FLUSH/FUA support for request-based dm") was an overly drastic (but simple) response to this situation. I have received a report that this BUG_ON was hit and now think it would be better to use dm_kill_unmapped_request() to fail the clone and original request with -EIO. map_request() will assign the valid target returned by dm_table_find_target to tio->ti. But when the target isn't valid tio->ti is never assigned (because map_request isn't called); so add a check for tio->ti != NULL to dm_done().

2012-09-26dm mpath: only retry ioctl when no paths if queue_if_no_path setMike Snitzer
When there are no paths and multipath receives an ioctl, it waits until a path becomes available. This behaviour is incorrect if the "queue_if_no_path" setting was not specified, as then the ioctl should be rejected immediately, which this patch now does. commit 35991652b ("dm mpath: allow ioctls to trigger pg init") should have checked if queue_if_no_path was configured before queueing IO. Checking for the queue_if_no_path feature, like is done in map_io(), allows the following table load to work without blocking in the multipath_ioctl retry loop: echo "0 1024 multipath 0 0 0 0" | dmsetup create mpath_nodevs Without this fix the multipath_ioctl will block with the following stack trace: blkid D 0000000000000002 0 23936 1 0x00000000 ffff8802b89e5cd8 0000000000000082 ffff8802b89e5fd8 0000000000012440 ffff8802b89e4010 0000000000012440 0000000000012440 0000000000012440 ffff8802b89e5fd8 0000000000012440 ffff88030c2aab30 ffff880325794040 Call Trace: [<ffffffff814ce099>] schedule+0x29/0x70 [<ffffffff814cc312>] schedule_timeout+0x182/0x2e0 [<ffffffff8104dee0>] ? lock_timer_base+0x70/0x70 [<ffffffff814cc48e>] schedule_timeout_uninterruptible+0x1e/0x20 [<ffffffff8104f840>] msleep+0x20/0x30 [<ffffffffa0000839>] multipath_ioctl+0x109/0x170 [dm_multipath] [<ffffffffa06bfb9c>] dm_blk_ioctl+0xbc/0xd0 [dm_mod] [<ffffffff8122a408>] __blkdev_driver_ioctl+0x28/0x30 [<ffffffff8122a79e>] blkdev_ioctl+0xce/0x730 [<ffffffff811970ac>] block_ioctl+0x3c/0x40 [<ffffffff8117321c>] do_vfs_ioctl+0x8c/0x340 [<ffffffff81166293>] ? sys_newfstat+0x33/0x40 [<ffffffff81173571>] sys_ioctl+0xa1/0xb0 [<ffffffff814d70a9>] system_call_fastpath+0x16/0x1b Signed-off-by: Mike Snitzer <snitzer@redhat.com> Cc: stable@vger.kernel.org # 3.5+ Acked-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2012-09-26dm thin: do not set discard_zeroes_dataMike Snitzer
The dm thin pool target claims to support the zeroing of discarded data areas. This turns out to be incorrect when processing discards that do not exactly cover a complete number of blocks, so the target must always set discard_zeroes_data_unsupported. The thin pool target will zero blocks when they are allocated if the skip_block_zeroing feature is not specified. The block layer may send a discard that only partly covers a block. If a thin pool block is partially discarded then there is no guarantee that the discarded data will get zeroed before it is accessed again. Due to this, thin devices cannot claim discards will always zero data.

%cr4 is supposed to reflect a set of features into which the operating system is opting in. If the BIOS or bootloader leaks bits here, this is not desirable. Consider a bootloader passing in %cr4.pae set to a legacy paging kernel, for example -- it will not have any immediate effect, but the kernel would crash when turning paging on. A similar argument applies to %eflags, and since we have to look for %eflags.id being settable we can use a sequence which clears %eflags as a side effect. Note that we already do this for x86-64.
