2011-06-23nanddump: document, warn about future default --omitoobBrian Norris
To work as a proper inverse to nandwrite, nanddump must not dump OOB data by default. This patch prints a warning regarding the future change. We also suggest using the new flag, `--oob', for transitioning to the next release with new default behavior. Note that we are changing `-o' to mean `--oob' in the next release, similar to `nandwrite -o'. This is a break from previous behavior.

2011-06-23nanddump: add --oob optionBrian Norris
Adds an explicit option for including OOB data in our data dump. Currently, this is the default behavior, but in the next release, the default will be to exclude OOB data. This is done to mirror the '-o' option in nandwrite. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <dedekind1@gmail.com>

2011-06-23nanddump: warn about new default BB handlingBrian Norris
In an upcoming release, we will no longer default to --bb=padbad. Instead, the default will be --bb=skipbad. This makes nanddump a better inverse operation to nandwrite. This patch prints warnings for users so that they get a chance to update their scripts before the default changes officially.

2011-06-23nanddump: update help message for BB method changesBrian Norris
--noskipbad will soon be replaced by --bb=dumpbad, and --omitbad is being removed entirely in favor of --bb=skipbad. This patch adds warnings when using inappropriate configurations and adds info to the help message. Please plan to migrate to the new usages shortly.

2011-06-23nanddump: remove --skipbad, leaving --bb=skipbadBrian Norris
We are moving to unify bad block handling methods under the --bb=METHOD option. Since --skipbad has not been included in a mtd-utils release yet, we can safely replace it without a deprecation and phase-out period.

2011-06-23nanddump: add --bb=METHOD optionBrian Norris
We have too many separate bad block handling methods: --omitbad --noskipbad --skipbad On top of these, we have the default option: that bad blocks are replaced with 0xFF. These options will be unified under --bb=METHOD. The end goal will be something like: ---------------------------------------------------------------------------------------------- Old option New option Comment ---------------------------------------------------------------------------------------------- <default> --bb=padbad dump flash data, substituting 0xFF for any bad blocks --noskipbad --bb=dumpbad dump flash data, including any bad blocks --skipbad --bb=skipbad dump good data, completely skipping any bad blocks (new default) --omitbad N/A very similar to `skipbad' (DEPRECTATED) The BB options are all mutually exclusive, so we check that we do not have more than one BB option explicitly enabled on the command line by tracking whether or not a BB method has been set by the user.

2011-06-09mtdinfo: add regioninfo/eraseblock map displayMike Frysinger
This brings the mtdinfo utility in line with the functionality of the flash_info utility. It dumps the erase regioninfo (if the devices has it) as well as showing a handy eraseblock map (if the user has requested it). The eraseblock map also shows which blocks are locked and which ones are bad. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2011-06-08libmtd: improve mtd_islocked interfaceArtem Bityutskiy
This patch first of all, re-names 'mtd_islocked()' into 'mtd_is_locked()' since this seems to be the name Mike wanted, and it looks a bit nicer. This patch also makes 'mtd_is_locked()' print an error message if it fails. I'm not sure if it is good idea for a library to do so, but all functions do this, so it certainly _not_ a good idea to be inconsistent. However, for the special case, when the the "is locked" ioctl is not supported or is not valid for this device, we do not print an error message and return ENOTSUPP error code. Thus, the user can distinguish between real errors and non-fatal "not supported" cases. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2011-06-06flash_{lock, unlock}: fix off-by-one error for "entire device" lengthSteven Miao
This basically reverts commit 43feb39f35a9ee0ed3 which changed the full length calculation to be one less than one sector. I don't understand the logic in the commit message where it states that the length should be one sector smaller as this results in misbehavior at runtime. For example, with a mtd device with total size 0x400000 and erase block size of 0x20000 (which gives us a total of 32 sectors), this new logic results in: mtdLockInfo.start = 0; mtdLockInfo.length = 0x3e0000; /* (32 - 1) * 0x20000 */ Calling MEMLOCK/MEMUNLOCK on the device with this range leaves the last sector unchanged which is certainly not what we want. So drop this -1 part of the calculation. To look at it another way, if we only attempt to lock one sector, this calculation would end up with the .length set to 0. Calling MEMLOCK with a length of 0 does not lock the sector as this simple code shows: int main(int argc, char *argv[]) { erase_info_t e0 = { 0, 0 }, e1 = { 0, 0x20000 }; int fd = open(argv[1], O_RDONLY); ioctl(fd, MEMUNLOCK, &e1); printf("%i\n", ioctl(fd, MEMISLOCKED, &e1)); ioctl(fd, MEMLOCK, &e0); printf("%i\n", ioctl(fd, MEMISLOCKED, &e1)); } MEMISLOCKED returns 0 both times. If we change the argument to MEMLOCK to e1, then MEMISLOCKED returns 1.

2011-06-06flash_{lock,unlock}: merge functionalityMike Frysinger
The flash_lock util has a bit of extra argument checking, and it supports a magic value of "-1" to mean "all blocks".

2011-06-06nanddump: add --skipbad option for bad blocksBrian Norris
This patch adds a new option "--skipbad" to nanddump. It is subtly different than "--omitbad". The following description was included in the help message to attempt to clarify the differences. Notes on --omitbad and --skipbad: With either option, we stop dumping data when we encounter a bad block and resume dumping at the next good block. However, with --omitbad, we count the bad block as part of the total dump length, whereas with --skipbad, the bad block is 'skipped,' that is, not counted toward the total dump length.

Currently pcv macro print the error message only if we are not doing power cut testing or if we have -v flag.

2011-05-27fs-tests: integck: EIO can also be return in power-cut testingArtem Bityutskiy
Currently when we are doing UBIFS power cut emulation testing we assume that EROFS is returned in case of an emulated power cut event. However, this is not true and sometimes Linux returns EIO to user-space instead. Namely, this happens when we are waiting for write-back to finish. Here is a call trace form kernel 2.6.39-rc7: Call Trace: [<ffffffff810aaa77>] filemap_write_and_wait_range+0x78/0xb1 [<ffffffff8110f34d>] vfs_fsync_range+0x38/0xd3 [<ffffffff8110f42b>] generic_write_sync+0x43/0x65 [<ffffffff810ab0c9>] generic_file_aio_write+0xaa/0xf2 [<ffffffffa02224c9>] ubifs_aio_write+0x13a/0x1a1 [ubifs] [<ffffffff810ed71f>] do_sync_write+0xcb/0x141 [<ffffffff810ee016>] vfs_write+0xb0/0x150 [<ffffffff810ee175>] sys_write+0x48/0x72 [<ffffffff813e0692>] system_call_fastpath+0x16/0x1b 'filemap_fdatawait_range()' returns hard-coded -EIO if a page write-back happens with whatever error code.

2011-05-27fs-tests: integck: implement MTD reattachingArtem Bityutskiy
This patch adds -m <mtdnum> option to integck and teaches integck to re-attach the MTD device to UBI in case of an emulated power cut event. This is needed for the new UBI power cut and unstable bits emulation infrastructure: when UBI emulates a power cut the only way to recover form this is to re-attach the MTD device.

This adds a superblock flag indicating that "free-space fixup" is needed, and allows it to be set by the user via the "-F" command-line option. The first time the filesystem is mounted, this flag will trigger a one-time re-mapping of all LEBs containing free space.

2011-05-20fs-tests: integck: make -v work -eArtem Bityutskiy
Make the verify option -v work with power cut emulation option -e. We can verify all operations except of writing to the file, because of write-back. Indeed, even if we write successfully, the pages may still be in the page-cache and if an emulated power cut happens they will be dropped, and our verification will fail. I am not 100% sure it is save to verify non-write operation in other FSes, but only UBIFS has power cut emulation mode now, so we do not really care about other FSes at this point.
