| cbf8ae3 | Roland Dreier | 07 June 2012, 21:21:13 UTC | btree: fix tree corruption in btree_get_prev() The memory the parameter __key points to is used as an iterator in btree_get_prev(), so if we save off a bkey() pointer in retry_key and then assign that to __key, we'll end up corrupting the btree internals when we do eg longcpy(__key, bkey(geo, node, i), geo->keylen); to return the key value. What we should do instead is use longcpy() to copy the key value that retry_key points to __key. This can cause a btree to get corrupted by seemingly read-only operations such as btree_for_each_safe.

| 7d8a456 | Will Deacon | 07 June 2012, 21:21:13 UTC | ipc: shm: restore MADV_REMOVE functionality on shared memory segments Commit 17cf28afea2a ("mm/fs: remove truncate_range") removed the truncate_range inode operation in favour of the fallocate file operation. When using SYSV IPC shared memory segments, calling madvise with the MADV_REMOVE advice on an area of shared memory will attempt to invoke the .fallocate function for the shm_file_operations, which is NULL and therefore returns -EOPNOTSUPP to userspace. The previous behaviour would inherit the inode_operations from the underlying tmpfs file and invoke truncate_range there. This patch restores the previous behaviour by wrapping the underlying fallocate function in shm_fallocate, as we do for fsync.

This exposes a bug in mlx4_common_set_port(), where the VL cap value passed in (inside the command mailbox) is incorrectly zeroed-out: mlx4_SET_PORT modifies the VL_cap field (byte 3 of the mailbox). Since the SET_PORT command is paravirtualized on the master as well as on the slaves, mlx4_SET_PORT_wrapper() is invoked on the master. This calls mlx4_common_set_port() where mailbox byte 3 gets overwritten by code which should only set a single bit in that byte (for the reset qkey counter flag) -- but instead overwrites the entire byte. The result is that when running in SR-IOV mode, the VL_cap will be set to zero -- fix this.

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 |

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.

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().

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.

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.

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.

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.

| 2e24e32 | Gabor Juhos | 23 May 2012, 22:17:23 UTC | mtd: block2mtd: fix recursive call of mtd_writev The 'mtd_writev' interface calls the function assigned to the '_write' field of a given mtd device if that is not NULL. The block2mtd driver sets the '_writev' field to the 'mtd_writev' function itself and thus causes a endless loop. This is caused by 1dbebd32562b3c2caeca35960e5cb00bfcc12900 (mtd: harmonize mtd_writev usage). Remove the assignment from the block2mtd driver to fix the issue.
