* block: wake up waiters when a queue is marked dyingJens Axboe2014-12-315-5/+42
| | | | | | | | | | | If it's dying, we can't expect new request to complete and come in an wake up other tasks waiting for requests. So after we have marked it as dying, wake up everybody currently waiting for a request. Once they wake, they will retry their allocation and fail appropriately due to the state of the queue.

| | | | | | | | | | | | | | | | | | | | | | | | Starting with commit v3.2-rc4-1-g02125a8, seq_path_root() no longer changes the value of its "struct path *root" argument. Starting with commit v3.2-rc7-104-g8c9379e, the "struct path *root" argument of seq_path_root() is const. As result, the temporary variable "root" in show_mountinfo() that holds a copy of struct path root is no longer needed. Signed-off-by: Dmitry V.

| * init: fix read-write root mountMiklos Szeredi2014-12-171-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If mount flags don't have MS_RDONLY, iso9660 returns EACCES without actually checking if it's an iso image. This tricks mount_block_root() into retrying with MS_RDONLY. This results in a read-only root despite the "rw" boot parameter if the actual filesystem was checked after iso9660. I believe the behavior of iso9660 is okay, while that of mount_block_root() is not. It should rather try all types without MS_RDONLY and only then retry with MS_RDONLY. This change also makes the code more robust against the case when EACCES is returned despite MS_RDONLY, which would've resulted in a lockup.

Instead of encrypting and decrypting lower files, it provides a unified view of the encrypted files in the lower filesystem. The presence of the ecryptfs_encrypted_view mount option is intended to force a read-only mount and modifying files is not supported when the feature is in use. See the following commit for more information: e77a56d [PATCH] eCryptfs: Encrypted passthrough This patch forces the mount to be read-only when the ecryptfs_encrypted_view mount option is specified by setting the MS_RDONLY flag on the superblock. Additionally, this patch removes some broken logic in ecryptfs_open() that attempted to prevent modifications of files when the encrypted view feature was in use. The check in ecryptfs_open() was not sufficient to prevent file modifications using system calls that do not operate on a file descriptor.

Also, after adding the regions to the free space caches, a fitrim ioctl call can see those ranges in a block group's free space cache and perform a discard on the ranges, so the same issue can happen without "-o discard" as well. This causes corruption, affecting one or multiple btree nodes (in the worst case leaving the fs unmountable) because some of those ranges (the ones in the fs_info->pinned_extents tree) correspond to btree nodes/leafs that are referred by the last committed super block - breaking the rule that anything that was committed by a transaction is untouched until the next transaction commits successfully. I ran into this while running in a loop (for several hours) the fstest that I recently submitted: [PATCH] fstests: add btrfs test to stress chunk allocation/removal and fstrim The corruption always happened when a transaction aborted and then fsck complained like this: _check_btrfs_filesystem: filesystem on /dev/sdc is inconsistent *** fsck.btrfs output *** Check tree block failed, want=94945280, have=0 Check tree block failed, want=94945280, have=0 Check tree block failed, want=94945280, have=0 Check tree block failed, want=94945280, have=0 Check tree block failed, want=94945280, have=0 read block failed check_tree_block Couldn't open file system In this case 94945280 corresponded to the root of a tree. Using frace what I observed was the following sequence of steps happened: 1) transaction N started, fs_info->pinned_extents pointed to fs_info->freed_extents[0]; 2) node/eb 94945280 is created; 3) eb is persisted to disk; 4) transaction N commit starts, fs_info->pinned_extents now points to fs_info->freed_extents[1], and transaction N completes; 5) transaction N + 1 starts; 6) eb is COWed, and btrfs_free_tree_block() called for this eb; 7) eb range (94945280 to 94945280 + 16Kb) is added to fs_info->pinned_extents (fs_info->freed_extents[1]); 8) Something goes wrong in transaction N + 1, like hitting ENOSPC for example, and the transaction is aborted, turning the fs into readonly mode.

Fix this by not performing a discard and not adding the ranges to the free space caches - it's useless from this point since the fs is now in readonly mode and we won't write free space caches to disk anymore (otherwise we would leak space) nor any new superblock. By not adding the ranges to the free space caches, it prevents other code paths from allocating that space and write to it as well, therefore being safer and simpler. This isn't a new problem, as it's been present since 2011 (git commit acce952b0263825da32cf10489413dec78053347).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Packard Bell EasyNote MX65 with AD1986A codec needs a few fixups, namely, the pin config overrides to set only the known I/O pins and the EAPD has to be turned on. In addition, add stereo mix input forcibly for avoiding the weird KDE behavior by this update. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=88251 Signed-off-by: Takashi Iwai <tiwai@suse.de>

The "len" variable doesn't *need* to be signed but it should be signed to make the code easier to read and audit.
