7838e05 Rafał Miłecki 04 June 2012, 18:18:03 UTC drm/radeon/hdmi: don't set SEND_MAX_PACKETS bit Many TVs and A/V receivers don't work with this bit set. Problem was confirmed using: Onkyo TX-SR605, Sony BRAVIA KDL-52X3500, Sony BRAVIA KDL-40S40xx. In theory this bit shouldn't affect audio engine when feeding it with data, however it seems it does. Driver fglrx doesn't set that bit in any of the above cases. This fixes a regression introduced by 3.5-rc1.

b7884eb Daniel Vetter 04 June 2012, 09:18:15 UTC drm/i915: hold forcewake around ring hw init Empirical evidence suggests that we need to: On at least one ivb machine when running the hangman i-g-t test, the rings don't properly initialize properly - the RING_START registers seems to be stuck at all zeros. Holding forcewake around this register init sequences makes chip reset reliable again. Note that this is not the first such issue: commit f01db988ef6f6c70a6cc36ee71e4a98a68901229 Author: Sean Paul <seanpaul@chromium.org> Date: Fri Mar 16 12:43:22 2012 -0400 drm/i915: Add wait_for in init_ring_common added delay loops to make RING_START and RING_CTL initialization reliable on the blt ring at boot-up.

To avoid copy&pasting of the HAS_FORCE_WAKE check I've added a new intel_info bit for that. v2: Fixup missing commas in static struct and properly handling the error case in init_ring_common, both noticed by Jani Nikula.

3eef891 Chris Wilson 04 June 2012, 16:05:40 UTC drm/i915: Mark the ringbuffers as being in the GTT domain By correctly describing the rinbuffers as being in the GTT domain, it appears that we are more careful with the management of the CPU cache upon resume and so prevent some coherency issue when submitting commands to the GPU later.

0640113 Linus Torvalds 04 June 2012, 18:00:45 UTC vfs: Fix /proc/<tid>/fdinfo/<fd> file handling Cyrill Gorcunov reports that I broke the fdinfo files with commit 30a08bf2d31d ("proc: move fd symlink i_mode calculations into tid_fd_revalidate()"), and he's quite right. The tid_fd_revalidate() function is not just used for the <tid>/fd symlinks, it's also used for the <tid>/fdinfo/<fd> files, and the permission model for those are different. So do the dynamic symlink permission handling just for symlinks, making the fdinfo files once more appear as the proper regular files they are. Of course, Al Viro argued (probably correctly) that we shouldn't do the symlink permission games at all, and make the symlinks always just be the normal 'lrwxrwxrwx'. That would have avoided this issue too, but since somebody noticed that the permissions had changed (which was the reason for that original commit 30a08bf2d31d in the first place), people do apparently use this feature. [ Basically, you can use the symlink permission data as a cheap "fdinfo" replacement, since you see whether the file is open for reading and/or writing by just looking at st_mode of the symlink. So the feature does make sense, even if the pain it has caused means we probably shouldn't have done it to begin with. ] Reported-and-tested-by: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 04 June 2012, 18:00:45 UTC

650a37f Len Brown 04 June 2012, 03:34:44 UTC tools/power turbostat: fix IVB support Initial IVB support went into turbostat in Linux-3.1: 553575f1ae048aa44682b46b3c51929a0b3ad337 (tools turbostat: recognize and run properly on IVB) However, when running on IVB, turbostat would fail to report the new couters added with SNB, c7, pc2 and pc7. So in scenarios where these counters are non-zero on IVB, turbostat would report erroneous residencey results. In particular c7 time would be added to c1 time, since c1 time is calculated as "that which is left over". Also, turbostat reports MHz capabilities when passed the "-v" option, and it would incorrectly report 133MHz bclk instead of 100MHz bclk for IVB, which would inflate GHz reported with that option.

d15cf7c Len Brown 04 June 2012, 03:24:00 UTC tools/power turbostat: fix un-intended affinity of forked program Linux 3.4 included a modification to turbostat to lower cross-call overhead by using scheduler affinity: 15aaa34654831e98dd76f7738b6c7f5d05a66430 (tools turbostat: reduce measurement overhead due to IPIs) In the use-case where turbostat forks a child program, that change had the un-intended side-effect of binding the child to the last cpu in the system. This change removed the binding before forking the child. This is a back-port of a fix already included in turbostat v2. Signed-off-by: Len Brown <len.brown@intel.com> 04 June 2012, 03:24:00 UTC

68e3e92 Linus Torvalds 04 June 2012, 03:05:57 UTC Revert "mm: compaction: handle incorrect MIGRATE_UNMOVABLE type pageblocks" This reverts commit 5ceb9ce6fe9462a298bb2cd5c9f1ca6cb80a0199. That commit seems to be the cause of the mm compation list corruption issues that Dave Jones reported. The locking (or rather, absense there-of) is dubious, as is the use of the 'page' variable once it has been found to be outside the pageblock range. So revert it for now, we can re-visit this for 3.6. If we even need to: as Minchan Kim says, "The patch wasn't a bug fix and even test workload was very theoretical".

752dc18 Hugh Dickins 02 June 2012, 07:27:47 UTC mm: fix warning in __set_page_dirty_nobuffers New tmpfs use of !PageUptodate pages for fallocate() is triggering the WARNING: at mm/page-writeback.c:1990 when __set_page_dirty_nobuffers() is called from migrate_page_copy() for compaction. It is anomalous that migration should use __set_page_dirty_nobuffers() on an address_space that does not participate in dirty and writeback accounting; and this has also been observed to insert surprising dirty tags into a tmpfs radix_tree, despite tmpfs not using tags at all. We should probably give migrate_page_copy() a better way to preserve the tag and migrate accounting info, when mapping_cap_account_dirty(). But that needs some more work: so in the interim, avoid the warning by using a simple SetPageDirty on PageSwapBacked pages.

2f9d3df Linus Torvalds 03 June 2012, 21:50:19 UTC vfs: move inode stat information closer together The comment above it says "Stat data, not accessed from path walking", but in fact some of inode fields we use for the common stat data was way down at the end of the inode, causing unnecessary cache misses for the common stat operations. The inode structure is pretty big, and this can change padding depending on field width, but at least on the common 64-bit configurations this doesn't change the size. Some of our inode layout has historically been to tro to avoid unnecessary padding fields, but cache locality is at least as important for layout, if not more. Noticed by looking at kernel profiles, and noticing that the "i_blkbits" access stood out like a sore thumb. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 03 June 2012, 21:50:19 UTC

a4dff30 Nicholas Bellinger 30 May 2012, 23:25:41 UTC target/file: Use O_DSYNC by default for FILEIO backends Convert to use O_DSYNC for all cases at FILEIO backend creation time to avoid the extra syncing of pure timestamp updates with legacy O_SYNC during default operation as recommended by hch. Continue to do this independently of Write Cache Enable (WCE) bit, as WCE=0 is currently the default for all backend devices and enabled by user on per device basis via attrib/emulate_write_cache. This patch drops the now unnecessary fd_buffered_io= token usage that was originally signalling when to explictly disable O_SYNC at backend creation time for buffered I/O operation. This can end up being dangerous for a number of reasons during physical node failure, so go ahead and drop this option for now when O_DSYNC is used as the default. Also allow explict FUA WRITEs -> vfs_fsync_range() call to function in fd_execute_cmd() independently of WCE bit setting.

cc8394d Joe Thornber 02 June 2012, 23:30:01 UTC dm thin: provide userspace access to pool metadata This patch implements two new messages that can be sent to the thin pool target allowing it to take a snapshot of the _metadata_. This, read-only snapshot can be accessed by userland, concurrently with the live target. Only one metadata snapshot can be held at a time. The pool's status line will give the block location for the current msnap. Since version 0.1.5 of the userland thin provisioning tools, the thin_dump program displays the msnap as follows: thin_dump -m <msnap root> <metadata dev> Available here: https://github.com/jthornber/thin-provisioning-tools Now that userland can access the metadata we can do various things that have traditionally been kernel side tasks: i) Incremental backups. By using metadata snapshots we can work out what blocks have changed over time. Combined with data snapshots we can ensure the data doesn't change while we back it up. A short proof of concept script can be found here: https://github.com/jthornber/thinp-test-suite/blob/master/incremental_backup_example.rb ii) Migration of thin devices from one pool to another. iii) Merging snapshots back into an external origin. iv) Asyncronous replication.

3599165 Mikulas Patocka 02 June 2012, 23:29:58 UTC dm mpath: allow ioctls to trigger pg init After the failure of a group of paths, any alternative paths that need initialising do not become available until further I/O is sent to the device. Until this has happened, ioctls return -EAGAIN. With this patch, new paths are made available in response to an ioctl too. The processing of the ioctl gets delayed until this has happened. Instead of returning an error, we submit a work item to kmultipathd (that will potentially activate the new path) and retry in ten milliseconds. Note that the patch doesn't retry an ioctl if the ioctl itself fails due to a path failure. Such retries should be handled intelligently by the code that generated the ioctl in the first place, noting that some SCSI commands should not be retried because they are not idempotent (XOR write commands). For commands that could be retried, there is a danger that if the device rejected the SCSI command, the path could be errorneously marked as failed, and the request would be retried on another path which might fail too. It can be determined if the failure happens on the device or on the SCSI controller, but there is no guarantee that all SCSI drivers set these flags correctly.

bad1a75 H.J. Lu 22 May 2012, 03:29:45 UTC x86, x32, ptrace: Remove PTRACE_ARCH_PRCTL for x32 When I added x32 ptrace to 3.4 kernel, I also include PTRACE_ARCH_PRCTL support for x32 GDB For ARCH_GET_FS/GS, it takes a pointer to int64. But at user level, ARCH_GET_FS/GS takes a pointer to int32. So I have to add x32 ptrace to glibc to handle it with a temporary int64 passed to kernel and copy it back to GDB as int32. Roland suggested that PTRACE_ARCH_PRCTL is obsolete and x32 GDB should use fs_base and gs_base fields of user_regs_struct instead. Accordingly, remove PTRACE_ARCH_PRCTL completely from the x32 code to avoid possible memory overrun when pointer to int32 is passed to kernel.

20e2a86 Paul Moore 01 June 2012, 05:54:56 UTC cipso: handle CIPSO options correctly when NetLabel is disabled When NetLabel is not enabled, e.g. CONFIG_NETLABEL=n, and the system receives a CIPSO tagged packet it is dropped (cipso_v4_validate() returns non-zero). In most cases this is the correct and desired behavior, however, in the case where we are simply forwarding the traffic, e.g. acting as a network bridge, this becomes a problem. This patch fixes the forwarding problem by providing the basic CIPSO validation code directly in ip_options_compile() without the need for the NetLabel or CIPSO code. The new validation code can not perform any of the CIPSO option label/value verification that cipso_v4_validate() does, but it can verify the basic CIPSO option format. The behavior when NetLabel is enabled is unchanged. Signed-off-by: Paul Moore <pmoore@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net> 01 June 2012, 18:18:29 UTC

1193755 Linus Torvalds 01 June 2012, 17:34:35 UTC Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull vfs changes from Al Viro. "A lot of misc stuff. The obvious groups: * Miklos' atomic_open series; kills the damn abuse of ->d_revalidate() by NFS, which was the major stumbling block for all work in that area. * ripping security_file_mmap() and dealing with deadlocks in the area; sanitizing the neighborhood of vm_mmap()/vm_munmap() in general. * ->encode_fh() switched to saner API; insane fake dentry in mm/cleancache.c gone. * assorted annotations in fs (endianness, __user) * parts of Artem's ->s_dirty work (jff2 and reiserfs parts) * ->update_time() work from Josef. * other bits and pieces all over the place. Normally it would've been in two or three pull requests, but signal.git stuff had eaten a lot of time during this cycle ;-/" Fix up trivial conflicts in Documentation/filesystems/vfs.txt (the 'truncate_range' inode method was removed by the VM changes, the VFS update adds an 'update_time()' method), and in fs/btrfs/ulist.[ch] (due to sparse fix added twice, with other changes nearby). * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (95 commits) nfs: don't open in ->d_revalidate vfs: retry last component if opening stale dentry vfs: nameidata_to_filp(): don't throw away file on error vfs: nameidata_to_filp(): inline __dentry_open() vfs: do_dentry_open(): don't put filp vfs: split __dentry_open() vfs: do_last() common post lookup vfs: do_last(): add audit_inode before open vfs: do_last(): only return EISDIR for O_CREAT vfs: do_last(): check LOOKUP_DIRECTORY vfs: do_last(): make ENOENT exit RCU safe vfs: make follow_link check RCU safe vfs: do_last(): use inode variable vfs: do_last(): inline walk_component() vfs: do_last(): make exit RCU safe vfs: split do_lookup() Btrfs: move over to use ->update_time fs: introduce inode operation ->update_time reiserfs: get rid of resierfs_sync_super reiserfs: mark the superblock as dirty a bit later ... 01 June 2012, 17:34:35 UTC

44fbbb3 Al Viro 30 April 2012, 22:24:46 UTC x86: get rid of calling do_notify_resume() when returning to kernel mode If we end up calling do_notify_resume() with !user_mode(refs), it does nothing (do_signal() explicitly bails out and we can't get there with TIF_NOTIFY_RESUME in such situations). Then we jump to resume_userspace_sig, which rechecks the same thing and bails out to resume_kernel, thus breaking the loop. It's easier and cheaper to check *before* calling do_notify_resume() and bail out to resume_kernel immediately. And kill the check in do_signal()... Note that on amd64 we can't get there with !user_mode() at all - asm glue takes care of that.
