* f2fs crypto: add encryption xattr supportJaegeuk Kim2015-05-281-0/+4

* f2fs crypto: add f2fs encryption KconfigJaegeuk Kim2015-05-281-0/+19
| | | | | | | | | | | | | | | This patch adds f2fs encryption config. This patch integrates: "ext4 crypto: require CONFIG_CRYPTO_CTR if ext4 encryption is enabled On arm64 this is apparently needed for CTS mode to function correctly. Otherwise attempts to use CTS return ENOENT." Signed-off-by: Michael Halcrow <mhalcrow@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

* f2fs: avoid value overflow in showing current statusJaegeuk Kim2015-05-281-1/+2
| | | | | | | | This patch fixes overflow when do cat /sys/kernel/debug/f2fs/status. If a section is relatively large, dist value can be overflowed. Reported-by: Yossi Goldfill <ygoldfill@radianmemory.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
* f2fs: support FALLOC_FL_ZERO_RANGEChao Yu2015-05-281-1/+105
| | | | | | | | | | | | | | | | | | | Now, FALLOC_FL_ZERO_RANGE flag in ->fallocate is supported in ext4/xfs. In commit, the semantics of this flag is descripted as following:" 1) Make sure that both offset and len are block size aligned. 2) Update the i_size of inode by len bytes. 3) Compute the file's logical block number against offset. If the computed block number is not the starting block of the extent, split the extent such that the block number is the starting block of the extent. 4) Shift all the extents which are lying between [offset, last allocated extent] towards right by len bytes. This step will make a hole of len bytes at offset." This patch implements fallocate's FALLOC_FL_ZERO_RANGE for f2fs.

* f2fs: support FALLOC_FL_COLLAPSE_RANGEChao Yu2015-05-281-3/+132
| | | | | | | | | | | | | | | | | | | Now, FALLOC_FL_COLLAPSE_RANGE flag in ->fallocate is supported in ext4/xfs. In commit, the semantics of this flag is descripted as following:" 1) It collapses the range lying between offset and length by removing any data blocks which are present in this range and than updates all the logical offsets of extents beyond "offset + len" to nullify the hole created by removing blocks. In short, it does not leave a hole. 2) It should be used exclusively. No other fallocate flag in combination. 3) Offset and length supplied to fallocate should be fs block size aligned in case of xfs and ext4. 4) Collaspe range does not work beyond i_size." This patch implements fallocate's FALLOC_FL_COLLAPSE_RANGE for f2fs. Signed-off-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
* f2fs: introduce f2fs_replace_block() for reuseChao Yu2015-05-283-10/+27
| | | | | | | | | | Introduce a generic function replace_block base on recover_data_page, and export it. So with it we can operate file's meta data which is in CP/SSA area when we invoke fallocate with FALLOC_FL_COLLAPSE_RANGE flag.

* f2fs: do not re-lookup nat cache with same nidChao Yu2015-05-281-1/+2
| | | | | | | | | | | | | | In set_node_addr, we try to lookup cached nat entry of inode and then set flag in it. But previously in this function, we have already grabbed nat entry with current node id, if the node id is the same as the one of inode, we do not need to lookup it in cache again. So this patch adds condition judgment for reducing unneeded lookup. Signed-off-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

* f2fs: introduce discard_map for f2fs_trim_fsJaegeuk Kim2015-05-285-30/+68
| | | | | | | | | | This patch adds a bitmap for discard issues from f2fs_trim_fs. There-in rule is to issue discard commands only for invalidated blocks after mount. Once mount is done, f2fs_trim_fs trims out whole invalid area. After ehn, it will not issue and discrads redundantly. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
* f2fs: revmove spin_lock for write_orphan_inodesJaegeuk Kim2015-05-281-3/+6
| | | | | | | This patch removes spin_lock, since this is covered by f2fs_lock_op already. And, we should avoid to use page operations inside spin_lock. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
* f2fs: split find_data_page according to specific purposesJaegeuk Kim2015-05-285-95/+68
| | | | | | | | | | | | | | | | This patch splits find_data_page as follows. 1. f2fs_gc - use get_read_data_page() with read only 2. find_in_level - use find_data_page without locked page 3. truncate_partial_page - In the case cache_only mode, just drop cached page. - Ohterwise, use get_lock_data_page() and guarantee to truncate Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

* f2fs: fix race on allocating and deallocating a dentry blockJaegeuk Kim2015-05-281-15/+12
| | | | | | | | | | | | | | | | | | | | | | | There are two threads: f2fs_delete_entry() get_new_data_page() f2fs_reserve_block() dn.blkaddr = XXX lock_page(dentry_block) truncate_hole() dn.blkaddr = NULL unlock_page(dentry_block) lock_page(dentry_block) fill the block from XXX address add new dentries unlock_page(dentry_block) Later, f2fs_write_data_page() will truncate the dentry_block, since its block address is NULL. The reason for this was due to the wrong lock order. In this case, we should do f2fs_reserve_block() after locking its dentry block. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

In that case, inode has not been modified actually. So I have added offset check routine that prevent to call the punch_hole().

| | | | | | | | | | | | | | | Our f2fs_acl_create is copied from posix_acl_create in ./fs/posix_acl.c and modified to avoid deadlock bug when inline_dentry feature is enabled. Dan Carpenter rewrites posix_acl_create in commit 2799563b281f ("fs/posix_acl.c: make posix_acl_create() safer and cleaner") to make this function more safer, so that we can avoid potential bug in its caller, especially for ocfs2.

That was how the world was when (57291ce pinctrl: core device tree mapping table parsing support) was written. In that case, there were instances where the pinctrl mutex was already held when pinctrl_register_map() was called, hence a "locked" parameter was passed to the function to indicate that the mutex was already locked (so we shouldn't lock it again). A few years ago in (42fed7b pinctrl: move subsystem mutex to pinctrl_dev struct), we switched to a separate pinctrl_maps_mutex. ...but (oops) we forgot to re-think about the whole "locked" parameter for pinctrl_register_map(). Basically the "locked" parameter appears to still refer to whether the bigger pinctrl_dev mutex is locked, but we're using it to skip locks of our (now separate) pinctrl_maps_mutex. That's kind of a bad thing(TM). Probably nobody noticed because most of the calls to pinctrl_register_map happen at boot time and we've got synchronous device probing. ...and even cases where we're asynchronous don't end up actually hitting the race too often. ...but after banging my head against the wall for a bug that reproduced 1 out of 1000 reboots and lots of looking through kgdb, I finally noticed this. Anyway, we can now safely remove the "locked" parameter and go back to a war-free, evil-free, and kernel-bug-free world.
