* UBIFS: change bud replay function conventionsArtem Bityutskiy2011-05-161-16/+12
| | | | | | | | | This is a minor preparation patch which changes 'replay_bud()' interface - instead of passing bud lnum, offs, jhead, etc directly, pass a pointer to the bud entry which contains all the information. The bud entry will be also needed in one of the following patches. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: substitute the replay tree with a replay listArtem Bityutskiy2011-05-162-100/+74
| | | | | | | | | | | This patch simplifies replay even further - it removes the replay tree and adds the replay list instead. Indeed, we just do not need to use a tree here - all we need to do is to add all nodes to the list and then sort it. Using RB-tree is an overkill - more code and slower. And since we replay buds in order, we expect the nodes to follow in _mostly_ sorted order, so the merge sort becomes much cheaper in average than an RB-tree.

* UBIFS: simplify replayArtem Bityutskiy2011-05-161-108/+59
| | | | | | | | | | | | | | | This patch simplifies the replay code and makes it smaller. First of all, we can notice that we do not really need to create bud replay entries and insert them to the replay tree, because the only reason we do this is to set buds lprops correctly at the end. Instead, we can just walk the list of buds at the very end and set lprops for each bud. This allows us to get rid of whole 'insert_ref_node()' function, the 'REPLAY_REF' flag, and several fields in 'struct replay_entry'. Then we can also notice that we do not need the 'flags' 'struct replay_entry' field, because there is only one flag - 'REPLAY_DELETION'. Instead, we can just add a 'deletion' bit fields. As a result, this patch deletes much more lines that in adds. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: store free and dirty space in the bud replay entryArtem Bityutskiy2011-05-161-2/+6
| | | | | | | This is just a small preparation patch which adds 'free' and 'drity' fields to 'struct bud_entry'. They will be used to set bud lprops. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: remove unnecessary stack variableArtem Bityutskiy2011-05-161-9/+8
| | | | | | | | | This is patch removes an unnecessary 'offs' variable from 'ubifs_wbuf_write_nolock()' - we can just keep 'wbuf->offs' up-to-date instead. This patch is very minor the only motivation for it was that it is cleaner to keep wbuf->offs up-to-date by the time we call 'ubifs_leb_write()'.

* UBIFS: double check that buds are replied in orderArtem Bityutskiy2011-05-161-0/+4
| | | | | | | | | | | Commit 52c6e6f990669deac3f370f1603815adb55a1dbd provides misleading infomation in the commit messages - buds are replied in order. And the real reason why that fix helped is probably because it made sure we seek head even in read-only mode (so deferred recovery will have seeked heads). This patch adds an assertion which will fire if we reply buds out of order. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

* UBIFS: improve debugging lprops scanning a littleArtem Bityutskiy2011-05-161-24/+18
| | | | | | | | | When doing the lprops extra check ('dbg_check_lprops()') we scan whole media. We even scan empty and freeable LEBs which may contain garbage, which we handle after scanning. This patch teach the lprops checking function ('scan_check_cb()') to avoid scanning for free and freeable LEBs and save time. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: fix a rare memory leak in ro to rw remounting pathArtem Bityutskiy2011-05-132-1/+3
| | | | | | | | | | When re-mounting from R/O mode to R/W mode and the LEB count in the superblock is not up-to date, because for the underlying UBI volume became larger, we re-write the superblock. We allocate RAM for these purposes, but never free it. So this is a memory leak, although very rare one. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Cc: stable@kernel.org
* UBIFS: fix inode size debugging check failureArtem Bityutskiy2011-05-131-1/+5
| | | | | | | | | | | | | | | | This patch fixes a problem with the following symptoms: UBIFS: deferred recovery completed UBIFS error (pid 15676): dbg_check_synced_i_size: ui_size is 11481088, synced_i_size is 11459081, but inode is clean UBIFS error (pid 15676): dbg_check_synced_i_size: i_ino 128, i_mode 0x81a4, i_size 11481088 It happens when additional debugging checks are enabled and we are recovering from a power cut. When we fixup corrupted inode size during recovery, we change them in-place and we change ui_size as well, but not synced_i_size, which causes this failure. This patch makes sure we change both fields and fixes the issue. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: fix debugging FS checking failureArtem Bityutskiy2011-05-131-6/+35
| | | | | | | | | | | | | | | | | | | | | | | | When the debugging self-checks are enabled, we go trough whole file-system after mount and check/validate every single node referred to by the index. This is implemented by the 'dbg_check_filesystem()' function. However, this function fails if we mount "unclean" file-system, i.e., if we mount the file-system after a power cut. It fails with the following symptoms: UBIFS DBG (pid 8171): ubifs_recover_size: ino 937 size 3309925 -> 3317760 UBIFS: recovery deferred UBIFS error (pid 8171): check_leaf: data node at LEB 1000:0 is not within inode size 3309925 The reason of failure is that recovery fixed up the inode size in memory, but not on the flash so far. So the value on the flash is incorrect so far, and would be corrected when we re-mount R/W. But 'check_leaf()' ignores this fact and tries to validate the size of the on-flash inode, which is incorrect, so it fails. This patch teaches the checking code to look at the VFS inode cache first, and if there is the inode in question, use that inode instead of the inode on the flash media. This fixes the issue.

* UBIFS: remove an unneeded checkArtem Bityutskiy2011-05-131-2/+7
| | | | | | | | | | | | | In 'ubifs_recover_size()' we have an "if (!e->inode && c->ro_mount)" statement. But if 'c->ro_mount' is true, then '!e->inode' must always be true as well. So we can remove the unnecessary '!e->inode' test and put an 'ubifs_assert(!e->inode)' instead. This patch also removes an extra trailing white-space in a debugging print, as well as adds few empty lines to 'ubifs_recover_size()' to make it a bit more readable.

* UBIFS: split ubifs_rcvry_gc_commitArtem Bityutskiy2011-05-131-27/+50
| | | | | | | | | | | Split the 'ubifs_rcvry_gc_commit()' function and introduce a 'grab_empty_leb()' heler. This cleans 'ubifs_rcvry_gc_commit()' a little and makes it a bit less of spagetti. Also, add a commentary which explains why it is crucial to first search for an empty LEB and then run commit. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: dump the stack on errors in failure mode tooArtem Bityutskiy2011-05-131-4/+1
| | | | | | | | | | | | When UBIFS is in the failure mode (used for power cut emulation testing) we for some reasons do not dump the stack in many places, e.g., in assertions. Probably at early days we had too many of them and disabled this to make the development easier, but then never enabled. Nowadays I sometimes observe assertion failures during power cut testing, but the useful stackdump is not printed, which is bad. This patch makes UBIFS always print the stackdump when debugging is enabled. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: print useful debugging messages when cannot recover gc_lnumArtem Bityutskiy2011-05-131-0/+2
| | | | | | | | If we fail to recover the gc_lnum we just return an error and it then it is difficult to figure out why this happened. This patch adds useful debugging information which should make it easier to debug the failure. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: remove dead GC LEB recovery piece of codeArtem Bityutskiy2011-05-131-12/+1
| | | | | | | | | | | This patch removes a piece of code in 'ubifs_rcvry_gc_commit()' which is never executed. We call 'ubifs_find_dirty_leb()' function with min_space = wbuf->offs, so if it returns us an LEB, it is guaranteed to have at lease 'wbuf->offs' bytes of free+dirty space. So we can remove the subsequent code which deals with "returned LEB has less than 'wbuf->offs' bytes of free+dirty space". This simplifies 'ubifs_rcvry_gc_commit()' a little. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: remove duplicated codeArtem Bityutskiy2011-05-132-48/+33
| | | | | | | | | | | | We have duplicated code in 'ubifs_garbage_collect()' and 'ubifs_rcvry_gc_commit()', which is about handling the special case of free LEB. In both cases we just want to garbage-collect the LEB using 'ubifs_garbage_collect_leb()'. This patch teaches 'ubifs_garbage_collect_leb()' to handle free LEB's so that the caller does not have to do this and the duplicated code is removed.

| | | | | | | | | | | Remove the following commentary from 'ubifs_file_mmap()': /* 'generic_file_mmap()' takes care of NOMMU case */ I do not understand what it means, and I could not find anything relater to NOMMU in 'generic_file_mmap()'.

* UBIFS: do not change debugfs file positionArtem Bityutskiy2011-05-131-1/+0
| | | | | | | | This patch is a tiny improvement which removes few bytes of code. UBIFS debugfs files are non-seekable and the file position is ignored, so do not increase it in the write handler. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: fix oops in lprops dump functionArtem Bityutskiy2011-05-131-1/+7
| | | | | | | | | | | | The 'dbg_dump_lprop()' is trying to detect journal head LEBs when printing, so it looks at the write-buffers. However, if we are in R/O mode, we de-allocate the write-buffers, so 'dbg_dump_lprop()' oopses. This patch fixes the issue. Note, this patch is not critical, it is only about the debugging code path, and it is unlikely that anyone but UBIFS developers would ever hit this issue.

* UBIFS: use ro_mount instead of MS_RDONLYArtem Bityutskiy2011-05-131-1/+5
| | | | | | | | | | | We have our own flags indicating R/O mode, and c->ro_mode is equivalent to MS_RDONLY. Let's be consistent and use UBIFS flags everywhere. This patch is just a minor cleanup. Additionally, add a comment that we are surprised with VFS behavior - as a reminder to look at this some day. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: use EROFS when emulating failuresArtem Bityutskiy2011-05-131-12/+12
| | | | | | | | | | | | | | | When the debugging failure emulation is enabled and UBIFS decides to emulate an I/O error, it uses EIO error code. In which case UBIFS switches into R/O mode later on. The for the user-space is that when a failure is emulated, the file-system sometimes returns EIO and sometimes EROFS. This makes it more difficult to implement user-space tests for the failure mode. Let's be consistent and return EROFS in all the cases. This patch is an improvement for the debugging code and does not affect the functionality at all.

| | | | | | | | | | | | This is just a tiny clean-up patch. The variable name for empty address space operations is "empty_aops".

* UBIFS: introduce lsave debuggingArtem Bityutskiy2011-05-131-0/+53
| | | | | | | | | Try to improve UBIFS testing coverage by randomly picking LEBs to store in lsave, rather than picking them optimally.

* UBIFS: make force in-the-gaps to be a general self-checkArtem Bityutskiy2011-05-133-19/+13
| | | | | | | | | | | | UBIFS can force itself to use the 'in-the-gaps' commit method - the last resort method which is normally invoced very very rarely. Currently this "force int-the-gaps" debugging feature is a separate test mode. But it is a bit saner to make it to be the "general" self-test check instead. This patch is just a clean-up which should make the debugging code look a bit nicer and easier to use - we have way too many debugging options. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: improve space checking debugging featureArtem Bityutskiy2011-05-135-19/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves the 'dbg_check_space_info()' function which checks whether the amount of space before re-mounting and after re-mounting is the same (remounting from R/O to R/W modes and vice-versa). The problem is that 'dbg_check_space_info()' does not save the budgeting information before re-mounting, so when an error is reported, we do not know why the amount of free space changed. This patches makes the following changes: 1. Teaches 'dbg_dump_budg()' function to accept a 'struct ubifs_budg_info' argument and print out the this argument. This way we may ask it to print any saved budgeting info, no only the current one. 2. Accordingly changes all the callers of 'dbg_dump_budg()' to comply with the changed interface. 3. Introduce a 'saved_bi' (saved budgeting info) field to 'struct ubifs_debug_info' and save the budgeting info before re-mounting there. 4. Change 'dbg_check_space_info()' and make it print both old and new budgeting information. 5. Additionally, save 'c->igx_gc_cnt' and print it if and error happens. This value contributes to the amount of free space, so we have to print it. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: rearrange the budget dumpArtem Bityutskiy2011-05-131-12/+18
| | | | | | | | | | | | Re-arrange the budget dump and make sure we first dump all the 'struct ubifs_budg_info' fields, and then the other information. Additionally, print the 'uncommitted_idx' variable. This change is required for to the following dumping function enhancement where it will be possible to dump saved 'struct ubifs_budg_info' objects, not only the current one.

* UBIFS: simplify dbg_dump_budg calling conventionsArtem Bityutskiy2011-05-133-12/+4
| | | | | | | | | | | | The current 'dbg_dump_budg()' calling convention is that the 'c->space_lock' spinlock is held. However, none of the callers actually use it from contects which have 'c->space_lock' locked, so all callers have to explicitely lock and unlock the spinlock. This is not very sensible convention. This patch changes it and makes 'dbg_dump_budg()' lock the spinlock instead of imposing this to the callers. This simplifies the code a little. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: introduce a separate structure for budgeting infoArtem Bityutskiy2011-05-1311-130/+135
| | | | | | | | | | | | | This patch separates out all the budgeting-related information from 'struct ubifs_info' to 'struct ubifs_budg_info'. This way the code looks a bit cleaner. However, the main driver for this is that we want to save budgeting information and print it later, so a separate data structure for this is helpful. This patch is a preparation for the further debugging output improvements. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: use __packed instead of __attribute__((packed))Artem Bityutskiy2011-05-131-14/+14
| | | | | | | | | | | | | | | | | | | There was an attempt to standartize various "__attribute__" and other macros in order to have potentially portable and more consistent code, see commit 82ddcb040570411fc2d421d96b3e69711c670328. Note, that commit refers Rober Love's blog post, but the URL is broken, the valid URL is: http://blog.rlove.org/2005/10/with-little-help-from-your-compiler.html Moreover, nowadays checkpatch.pl warns about using __attribute__((packed)): "WARNING: __packed is preferred over __attribute__((packed))" It is not a big deal for UBIFS to use __packed, so let's do it.

* UBIFS: make debugfs files non-seekableArtem Bityutskiy2011-05-131-2/+2
| | | | | | | | | | | | | Turn the debufs files UBIFS maintains into non-seekable. Indeed, none of them is supposed to be seek'ed. Do this by making the '.lseek()' handler to be 'no_llseek()' and by using 'nonseekable_open()' in the '.open()' operation. This does mean an API break but this debugging API is only used by a couple of test scripts which do not rely in the 'llseek()' operation. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* Don't lock guardpage if the stack is growing upMikulas Patocka2011-05-091-5/+7
| | | | | | | | | | | | | | | | | | | | | Linux kernel excludes guard page when performing mlock on a VMA with down-growing stack. However, some architectures have up-growing stack and locking the guard page should be excluded in this case too. This patch fixes lvm2 on PA-RISC (and possibly other architectures with up-growing stack). lvm2 calculates number of used pages when locking and when unlocking and reports an internal error if the numbers mismatch.
