2012-02-02mtdinfo: fix `--all' for non-consecutive device numbersBrian Norris
When we have assigned non-consecutive device numbers to our MTD devices, then we run `mtdinfo --all', we get errors once mtdinfo tries to process the devices in the "hole". For instance, suppose that at boot time, we have one MTD (/dev/mtd0) then perform a sequence like the following: # modprobe mtdram # modprobe nandsim # rmmod mtdram Then at this point, we have should have devices 0 and 2 without 1. Then: # mtdinfo --all ... mtdinfo: error!: mtd1 does not correspond to any existing MTD device We add a check to first see if device is present, then continue to the next ID if it doesn't exist.

2012-01-27ubinfo: fix `--all' for non-consecutive device numbersBrian Norris
When we have assigned non-consecutive device numbers to our UBI devices, then we run `ubinfo --all', we get errors once ubinfo tries to process the devices in the "hole". For instance, suppose there are two UBI devices, /dev/ubi0 and /dev/ubi10; then, ubinfo will fail trying to open /dev/ubi1 with: ubinfo: error!: cannot get information about UBI device 1 error 2 (No such file or directory) This patch adds a check to first see if device is present, then continue to the next ID if it doesn't exist.

2012-01-13libmtd: Variable name same as function name causing compile to fail (Android)Thomas Cannon
When compiling mtd-utils against Android's bionic libc using the supplied cross compiler environment it errors: lib/libmtd.c: In function 'dev_node2num': lib/libmtd.c:444: error: called object 'major' is not a function lib/libmtd.c:445: error: called object 'minor' is not a function lib/libmtd.c: In function 'mtd_probe_node': lib/libmtd.c:1384: error: called object 'major' is not a function lib/libmtd.c:1385: error: called object 'minor' is not a function This patch updates the variable names for "major" and "minor" in two places. It then compiles cleanly. Artem: pick different names, also rename major1/minor1 variables for consistency.

2011-12-12libmtd: allow write operations when MEMWRITE is not supportedBrian Norris
MEMWRITE is a recently introduced write interface for MTD; however, it is only supported on NAND flash. mtd-utils should fall back to old write methods when either ENOTTY or EOPNOTSUPP are returned. This is a showstopper when, for instance, using ubiformat on NOR, which don't have a mtd->write_oob interface (and thus don't support MEMWRITE): ubiformat: formatting eraseblock 2 -- 1 % complete libmtd: error!: MEMWRITE ioctl failed for eraseblock 2 (mtd3) error 122 (Operation not supported) Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@linux.intel.com>

If a seed is not provided via --seed, we use the default rand() values, which produces the same sequence of values every run. Since this is undesirable, we should choose a random seed via the current time(). Note that this patch moves the srand() until after all the initial options processing.

2011-11-18mtdinfo: provide info when used without argumentsBrian Norris
If the user specifies neither a MTD argument nor the `-a' flag, we print a cryptic message; i.e., # mtdinfo libmtd: error!: cannot get information about "(null)" error 14 (Bad address) mtdinfo: error!: cannot get information about MTD device "(null)" error 14 (Bad address) This is a regression; previously, mtdinfo would give some short info about number of devices, etc. when used without arguments. To fix this, we revert commit d53c03b0989f8354a7e4dbb947a150fc7fe3f6d1 and call print_general_info() when no device is specified.

2011-09-19ubiformat: handle write errors correctlyArtem Bityutskiy
This issue was reported and analyzed by Anton Olofsson <anol.martinsson@gmail.com>: when ubiformat encounters a write error while flashing the UBI image (which may come from a file of from stdout), it correctly marks the faulty eraseblock as bad and skips it. However, it also incorrectly drops the data buffer which was supposed to be written, and reads next block of data. This patch fixes this issue - in case of a write error, we preserve the current data and write it to the next eraseblock, instead of dropping it.

2011-09-11nandwrite: re-implement `--autoplace' optionBrian Norris
The restructuring of mtd_write() has allowed us to use `--autoplace' somewhat successfully; it is supported by the new ioctl(MEMWRITE) as well as some legacy code utilizing the deprecated ioctl(MEMGETOOBSEL).

2011-09-11nandwrite: kill `--raw' optionBrian Norris
The `--raw' option has lost all usefulness as it overlapped with several other OOB modes. I cannot even figure out what it was actually intended to do, but I'm sure its functionality fits somewhere in the MTD_OPS_{AUTO_OOB,PLACE_OOB,RAW} options, which are mostly implemented in libmtd's mtd_write(). I don't think users need a warning for this one, unless someone can tell me what it actually was supposed to have done in the first place.

2011-09-11mtdutils: move OOB auto-layout into libmtd's mtd_writeBrian Norris
With the addition of the the new ioctl(MEMWRITE), we can use the kernel's internal OOB autoplacement option. It's a cleaner interface and avoids too much duplication of coding effort. This patch moves any legacy code (using MEMGETOOBSEL) into a legacy function in libmtd.c. It's not exactly a "pre-2.6.30" feature, so I'm not moving it to libmtd_legacy.c. Now, autoplacement features are only activated if we call mtd_write with mode == MTD_OPS_AUTO_OOB. This should fix some discrepancies for nandwrite, where we weren't handling OOB consistently (i.e., we had different functionality when the kernel did/didn't support MEMWRITE). But that also means that we now default to using MTD_OPS_PLACE_OOB instead of AUTO layout. To re-enable autoplacement, we can re-implement the `--autoplace' option that had previously rotted. This patch also cleans up a need for an extra OOB buffer in nandwrite. This has been tested a little in nandsim as well as on SLC NAND flash.

2011-09-11nandwrite: merge `mtd_write_oob' and `mtd_write' callsBrian Norris

2011-09-11libmtd: support MEMWRITE ioctlBrian Norris
`mtd_write()' now will first attempt to use MEMWRITE. Then, if that doesn't exist, it will attempt to fall back to old methods for writing OOB and/or page data. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@intel.com>
2011-09-11libmtd: modify `mtd_write' to cover OOB writesBrian Norris
To support the MEMWRITE ioctl, we will need a different sort of libmtd interface for writing to flash. We will expand mtd_write to include more functionality; for now, we just change the function definition and description as we begin to add the actual functionality.

2011-08-23nandwrite: cleanup "oobinfochanged" leftoversBrian Norris
We don't really use oobinfochanged anymore, since all the calls to the MEMSETOOBSEL ioctls are gone. The remaining usage of it is superfluous now, as the only case where it is changed is under the "noecc" condition and the only case where it is tested is under the "!noecc" condition. We also no longer need the "restoreoob" label and can instead simply close everything done with the single remaining label, "closeall". Note that `close(-1)' is legal, although useless. Finally, we move `old_oobinfo' into the only block of code in which it's used now.

2011-08-23nandwrite: kill -j, -y, and -f optionsBrian Norris
The legacy -j (--jffs2) and -y (--yaffs) options haven't been operational for a long time, since MEMSETOOBSEL was killed. I don't think anybody will miss these options (correct me if I'm wrong). They can be replaced by proper usage of MTD_OOB_AUTO modes. The -f (--forcelegacy) option went hand in hand with -j and -y. Now that -j and -y are gone, there's no use for -f. Kill it.

2011-08-23nandwrite: remove `autoplace' featuresBrian Norris
The `autoplace' option was meant to force an MTD_OOB_AUTO layout while writing to flash. This option has not been properly supported for a very long time, as the necessary ioctl, MEMSETOOBSEL, has been removed. Apparently nobody uses this option. Kill it. Other code depends on the availability of the `old_oobinfo' data, so we move some code within a block that handles autoplacement if it's *already* enabled. This, however, is inconsistent and should be cleaned up shortly. Note: this option may be re-implemented in the near future with the addition of a new ioctl that allows on-the-fly chaning of MTD OOB modes.
