From 8bf8c376ab2eefaf0386f4e003e720e1434fa43d Mon Sep 17 00:00:00 2001 From: Dmitry Monakhov Date: Wed, 3 Mar 2010 06:28:06 +0300 Subject: blkdev: fix merge_bvec_fn return value checks v2 merge_bvec_fn() returns bvec->bv_len on success. So we have to check against this value. But in case of fs_optimization merge we compare with wrong value. This patch must be included in b428cd6da7e6559aca69aa2e3a526037d3f20403 But accidentally i've forgot to add this in the initial patch. To make things straight let's replace all such checks. In fact this makes code easy to understand.

This had the effect of limiting the amount of allocation we could get for the local alloc during times when the window size was shrunk due to fragmentation. In some cases, that could actually *increase* fragmentation by artificially limiting the number of bits we can accept. So while we still want to ask for a minimum number of bits equal to window size, there is no reason why we should limit the number of bits the local alloc should accept.

The wipe is done by ocfs2_xa_block_wipe_namevalue() when the xattr is in the inode or block. We currently adjust name_offset for all the entries which have (offset < name_offset). This does not adjust the entrie we're replacing. Since we are replacing the entry, we don't adjust the total entry count. When we calculate a new namevalue location, we trust the entries now-wrong offset in ocfs2_xa_get_free_start(). The solution is to also adjust the name_offset for the replaced entry, allowing ocfs2_xa_get_free_start() to calculate the new namevalue location correctly.

But the request completion removes the request from the tree, so r_node was always undefined at this point. Since it's a small race, it usually led to a valid request, but not always. The result was an occasional crash in rb_next() while dereferencing node->rb_left. Fix this by clearing the rb_node when removing the request from the request tree, and not walking off into the weeds when we are done waiting for a request. Since the request we waited on will _always_ be out of the request tree, take a ref on the next request, in the hopes that it won't be. But if it is, it's ok: we can start over from the beginning (and traverse over older read requests again).

The rule is that all inodes in the orphan dir have ORPHANED_FL, otherwise we treated it as an ERROR. This rule works well except for some rare cases of reflink operation: http://oss.oracle.com/bugzilla/show_bug.cgi?id=1215 The problem is caused by how reflink and our orphan_scan thread interact. * The orphan scan pulls the orphans into a queue first, then runs the queue at a later time. We only hold the orphan_dir's lock during scanning. * Reflink create a oprhaned target in orphan_dir as its first step. It removes the target and clears the flag as the final step. These two steps take the orphan_dir's lock, but it is not held for the duration. Based on the above semantics, a reflink inode can be moved out of the orphan dir and have its ORPHANED_FL cleared before the queue of orphans is run. This leads to a ERROR in ocfs2_query_wipde_inode(). This patch teaches ocfs2_query_wipe_inode() to detect previously orphaned reflink targets. If a reflink fails or a crash occurs during the relfink operation, the inode will retain ORPHANED_FL and will be properly wiped.

This is due to the use of the continue_replay variable to short circuit the journal scanning. If it's set, it's assumed that there are transactions to replay, but there may not be. If it's unset, it's assumed that there aren't any, and that may not be the case either. I've observed two failure cases: 1) Where a clean file system on a read-only device refuses to mount 2) Where a clean file system on a read-only device passes the optimization and then tries writing the journal header to update the latest mount id. The former is easily observable by using a freshly created file system on a read-only loopback device. This patch moves the check into journal_read_transaction, where it can bail out before it's about to replay a transaction. That way it can go through and skip transactions where appropriate, yet still refuse to mount a file system with outstanding transactions.

However, unline the same ext4 change, it didn't actually change the name of the field when it changed the semantics of it. As a result, an old use of 'i_state' remained in fs/ext3/ialloc.c that initialized the field to EXT3_STATE_NEW. And that does not work _at_all_ when we're now working with individually named bits rather than values that get masked. So the code tried to mark the state to be new, but in actual fact set the field to EXT3_STATE_JDATA. Which makes no sense at all, and screws up all the code that checks whether the inode was newly allocated. In particular, it made the xattr code unhappy, and caused various random behavior, like apparently https://bugzilla.redhat.com/show_bug.cgi?id=577911 So fix the initialization, and rename the field to match ext4 so that we don't have this happen again.

Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

The error label releases the lock before calling journal_release_error, but it requires that the lock be held. do_journal_release unlocks and retakes it. When it releases it without it held, we trigger a BUG(). The error_alloc label skips the unlock since the lock isn't held yet but none of the other conditions that are clean up exist yet either. This patch returns immediately after the kzalloc failure and moves the reiserfs_write_unlock after the journal_release_error call.

This is a problem because in find_free_extent we just assume that we will find the right space_info for the allocation we want. But if we failed to read the block groups, we won't have setup any space_info's, and we'll hit a NULL pointer deref in find_free_extent. This patch fixes that problem by checking the return value of btrfs_read_block_groups, and failing out properly. I've also added a check in find_free_extent so if for some reason we don't find an appropriate space_info, we just return -ENOSPC.

But, it misses the case where the leaf changed and now has enough room for the item we want to insert. This adds an extra check to make sure the leaf really needs splitting before we call btrfs_split_leaf(), which keeps us from trying to split a leaf with a single item. btrfs_split_leaf() will blindly split the single item leaf, leaving us with one good leaf and one empty leaf and then a crash.

We now call through generic_file_aio_write -> generic_write_sync -> vfs_fsync_range. vfs_fsync_range has: if (!fop || !fop->fsync) { ret = -EINVAL; goto out; } But drivers/char/raw.c doesn't set an fsync method. We have two options: fix it or remove the raw driver completely. I'm happy to do either, the fact this has been broken for so long suggests it is rarely used. The patch below adds an fsync method to the raw driver. My knowledge of the block layer is pretty sketchy so this could do with a once over. If we instead decide to remove the raw driver, this patch might still be useful as a backport to 2.6.33 and 2.6.32.
