2011-07-04UBIFS: introduce more I/O helpersArtem Bityutskiy5-87/+148
Introduce the following I/O helper functions: 'ubifs_leb_read()', 'ubifs_leb_write()', 'ubifs_leb_change()', 'ubifs_leb_unmap()', 'ubifs_leb_map()', 'ubifs_is_mapped(). The idea is to wrap all UBI I/O functions in order to encapsulate various assertions and error path handling (error message, stack dump, switching to R/O mode). And there are some other benefits of this which will be used in the following patches. This patch does not switch whole UBIFS to use these functions yet. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: always print stacktrace when switching to R/O modeArtem Bityutskiy1-1/+1
When switching to R/O mode due to an I/O error, always dump the stack, not only when debugging is enabled. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: remove unused and unneeded debugging functionArtem Bityutskiy2-57/+3
This patch contains several minor clean-up and preparational cahnges. 1. Remove 'dbg_read()', 'dbg_write()', 'dbg_change()', and 'dbg_leb_erase()' functions as they are not used. 2. Remove 'dbg_leb_read()' and 'dbg_is_mapped()' as they are not really needed, it is fine to let reads go through in failure mode. 3. Rename 'offset' argument to 'offs' to be consistent with the rest of UBIFS code. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: add global debugfs knobsArtem Bityutskiy2-16/+157
Now we have per-FS (superblock) debugfs knobs, but they have one drawback - you have to first mount the FS and only after this you can switch self-checks on/off. But often we want to have the checks enabled during the mount. Introduce global debugging knobs for this purpose. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: introduce debugfs helpersArtem Bityutskiy1-20/+56
Separate out pieces of code from the debugfs file read/write functions and create separate 'interpret_user_input()'/'provide_user_output()' helpers. These helpers will be needed in one of the following patches, so this is just a preparational change. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: re-arrange debugging code a bitArtem Bityutskiy1-59/+59
Move 'dbg_debugfs_init()' and 'dbg_debugfs_exit()' functions which initialize debugfs for whole UBIFS subsystem below the code which initializes debugfs for a particular UBIFS instance. And do the same for 'ubifs_debugging_init()' and 'ubifs_debugging_exit()' functions. This layout is a bit better for the next patches, so this is just a preparation. Also, rename 'open_debugfs_file()' into 'dfs_file_open()' for consistency. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: be more informative in failure modeArtem Bityutskiy1-15/+23
When we are testing UBIFS recovery, it is better to print in which eraseblock we are going to fail. Currently UBIFS prints it only if recovery debugging messages are enabled, but this is not very practical. So change 'dbg_rcvry()' messages to 'ubifs_warn()' messages. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: switch self-check knobs to debugfsArtem Bityutskiy2-53/+159
UBIFS has many built-in self-check functions which can be enabled using the debug_chks module parameter or the corresponding sysfs file (/sys/module/ubifs/parameters/debug_chks). However, this is not flexible enough because it is not per-filesystem. This patch moves this to debugfs interfaces. We already have debugfs support, so this patch just adds more debugfs files. While looking at debugfs support I've noticed that it is racy WRT file-system unmount, and added a TODO entry for that. This problem has been there for long time and it is quite standard debugfs PITA. The plan is to fix this later. This patch is simple, but it is large because it changes many places where we check if a particular type of checks is enabled or disabled. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: lessen amount of debugging check typesArtem Bityutskiy5-25/+12
We have too many different debugging checks - lessen the amount by merging all index-related checks into one. At the same time, move the "force in-the-gap" test to the "index checks" class, because it is too heavy for the "general" class. This patch merges TNC, Old index, and Index size check and calles this just "index checks". Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: introduce helper functions for debugging checks and testsArtem Bityutskiy12-56/+75
This patch introduces helper functions for all debugging checks, so instead of doing if (!(ubifs_chk_flags & UBIFS_CHK_GEN)) we now do if (!dbg_is_chk_gen(c)) This is a preparation to further changes where the flags will go away, and we'll need to only change the helper functions, but the code which utilizes them won't be touched. At the same time this patch removes 'dbg_force_in_the_gaps()', 'dbg_force_in_the_gaps_enabled()', and dbg_failure_mode helpers for consistency. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: amend debugging inode size check function prototypeArtem Bityutskiy4-6/+9
Add 'const struct ubifs_info *c' parameter to 'dbg_check_synced_i_size()' function because we'll need it in the next patch when we switch to debugfs. So this patch is just a preparation. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: amend debugging name check function prototypeArtem Bityutskiy1-3/+5
Add 'struct ubifs_info *c' parameter to the 'dbg_check_name()' debugging function - it will be needed in one of the following commits where we switch to debugfs. So this is just a preparation. Mark parameters as 'const' while on it. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: add few commentaries about TNCArtem Bityutskiy1-0/+26
Add a couple of comments - while looking into TNC I could not easily figure out few facts, so it is a good idea to document them in the code. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: use correct flags in lpropsArtem Bityutskiy3-8/+8
The UBIFS lpt tree is in many aspects similar to the TNC tree, and we have similar flags for these trees. And by mistake we use the COW_ZNODE flag for LPT in some places, instead of the right flag COW_CNODE. And this works only because these two constants have the same value. This patch makes all the LPT code to use COW_CNODE and also changes COW_CNODE constant value to make sure we do not misuse the flags any more. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: harmonize znode flag helpersArtem Bityutskiy4-12/+34
We have 3 znode flags: cow, obsolete, dirty. For the last flag we have a 'ubifs_zn_dirty()' helper function, but for the other 2 flags we use 'test_bit()' directly. This patch makes the situation more consistent and introduces helpers for the other 2 flags: 'ubifs_zn_cow()' and 'ubifs_zn_obsolete()'. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: remove dead codeArtem Bityutskiy1-76/+30
Remove dead pieces of code under "if (c->min_io_size == 1)" statement - we never execute it because in UBIFS 'c->min_io_size' is always at least 8. This are leftovers from old pre-mainline prototype. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: remove unnecessary bracketsArtem Bityutskiy1-1/+1

2011-07-04UBIFS: minor cleanup: use S_ISREG helperArtem Bityutskiy1-1/+1

2011-07-04UBIFS: improve inode dumping functionArtem Bityutskiy3-5/+60
Teach 'dbg_dump_inode()' dump directory entries for directory inodes. This requires few additional changes: 1. The 'c' argument of 'dbg_dump_inode()' cannot be const any more. 2. Users of 'dbg_dump_inode()' should not have 'tnc_mutex' locked. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: dump stack when pnode or nnode reading failsArtem Bityutskiy1-0/+2
When we fail to read a pnode or nnode - print stacktrace if debugging is enabled. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: lessen the size of debugging info data structureArtem Bityutskiy2-7/+22
This patch lessens the 'struct ubifs_debug_info' size by 90 bytes by allocating less bytes for the debugfs root directory name. It introduces macros for the name patter an length instead of hard-coding 100 bytes. It also makes UBIFS use 'snprintf()' and teaches it to gracefully catch situations when the name array is too short. Additionally, this patch makes 2 unrelated changes - I just thought they do not deserve separate commits: simplifies 'ubifs_assert()' for non-debugging case and makes 'dbg_debugfs_init()' properly verify debugfs return code which may be an error code or NULL, so we should you 'IS_ERR_OR_NULL()' instead of 'IS_ERR()'. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-07-04UBIFS: return EROFS in case of broken commitArtem Bityutskiy1-2/+2
If commit failed and it is in broken state, UBIFS switches to R/O mode. Most operations return -EROFS in this case, except of commit which returns -EINVAL. Make it return -EROFS too for consistency. This is also important for our power cut emulation testing. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

When iputting the inode, We may leave the delayed nodes if they have some delayed items that have not been dealt with.
