2015-11-11flash_{un,}lock: don't allow "last byte + 1"Brian Norris
A lock/unlock/islocked ioctl() should be prevented from anything past the last byte, inclusive. But we were doing an exclusive check. This isn't a big deal, as the kernel MTD APIs would be guarding this anyway, but let's do this for completeness. Signed-off-by: Brian Norris <computersforpeace@gmail.com>
2015-11-11flash_{un,}lock: improve strtol() error handlingBrian Norris
Use the simple_* helpers to improve error checking. Also fixup brace style at the same time. Signed-off-by: Brian Norris <computersforpeace@gmail.com>
2015-11-11flash_{un,}lock: add MEMISLOCKED supportBrian Norris
With the -i / --islocked flags. Sample output: # flash_lock --islocked /dev/mtd0 Device: /dev/mtd0 Start: 0 Len: 0x400000 Lock status: unlocked Return code: 0 Signed-off-by: Brian Norris <computersforpeace@gmail.com>
2015-11-11flash_{un,}lock: support both lock/unlock in the same binaryBrian Norris
Add new --lock/--unlock flags, so we can do either with the same binary. This will prepare for the addition of other features, so we don't have to keep duplicating the same binary via #include "flash_unlock.c". The defaults still work as expected: flash_unlock will default to REQUEST_UNLOCK, and flash_lock will default to REQUEST_LOCK. Eventually, we might deprecate one of the two (flash_unlock, probably), so we only have to ship one flash_{un,}lock binary. Signed-off-by: Brian Norris <computersforpeace@gmail.com>

2015-11-11flash_{un,}lock: abstract the argument positionsBrian Norris
Previously, there were no options (besides stand-alone --help and --version), so we just used fixed-position argv indexes. Let's change that. Also clean up the sanity checks a bit to make them more verbose and specific. Signed-off-by: Brian Norris <computersforpeace@gmail.com>

2015-11-11flash_{un,}lock: nest optional parameters in help messageBrian Norris
block count should be nested within the optional offset listing. That is, we require offset before we accept a block count. Signed-off-by: Brian Norris <computersforpeace@gmail.com>
2015-11-11nandtest: support hex/dec/oct for --offset and --lengthBrian Norris
These two options are handled inconsistently, which caused an unnecessary amount of head scratching. Let's just use the simple helpers too, so we get the error handling right. Signed-off-by: Brian Norris <computersforpeace@gmail.com>

2015-08-31don't include system headers in dependency filesBrian Norris

2015-08-28autogenerated dependency files are not being utilized properlyBrian Norris
TL;DR Acked-by: Mike Frysinger <vapier@gentoo.org> ===== Auto-generated dependency rules are not being written correctly, so changes to dependent files (e.g., headers) do not actually trigger rebuilds. The problem =========== It appears that when a dependency generation flag is passed directly to the preprocessor (with '-Wp,...'), it loses information about the output path. So, it just makes up the output name as $(basename).o, with no path information. This yields .*.c.dep files that look like this: flash_lock.o: flash_lock.c /usr/include/stdc-predef.h flash_unlock.c \ (...) and nanddump.o: nanddump.c /usr/include/stdc-predef.h /usr/include/ctype.h \ (...) include/libmtd.h This is the case for both in-tree *and* out-of-tree builds. Naturally, this is a problem for out-of-tree builds. But it is also a problem for in-tree builds, because we use rules like this for builds: $(BUILDDIR)/%.o: %.c and make doesn't recognize $(BUILDDIR)/%.o as the same as %.o even when $(BUILDDIR) == $(PWD). Example failures ================ ## Rebuilding after touching common header doesn't recompile anything $ make (...) $ touch include/libmtd.h $ make CHK include/version.h ## Same for out-of-tree builds $ BUILDDIR=test make (...) $ touch include/libmtd.h $ BUILDDIR=test make CHK include/version.h I noticed this when seeing that flash_lock would not get rebuilt when modifying flash_unlock.c (where 99% of the source code lies): $ make (...) $ touch flash_unlock.c $ make CHK include/version.h CC flash_unlock.o LD flash_unlock The fix ======= Just pass -MD straight to the compiler, and make sure to specify the output file for the dependency info with -MF.

2015-05-28mkfs.ubifs: Fix build with gcc 5.1Bernhard Walle
In gcc 5.1, the default C standard which is used to compile a C file, has changed from gnu89 to gnu11. This changed the meaning of 'extern inline'. See https://gcc.gnu.org/gcc-5/porting_to.html. In mkfs.ubifs, this leads to multiple definitions of hashtable_iterator_key and -hashtable_iterator_value. I think the most pragmatic way to fix the issue is to replace 'extern inline' with 'static inline' here.

2014-11-04libmtd: don't ignore "region index" parameter in mtd_regioninfo()Brian Norris
ioctl(MEMGETREGIONINFO) has one input parameter (regionindex) and three output parameters (info about the erase region). There are two problems in mtdinfo/libmtd here: 1. mtdinfo.c doesn't initialize its region_info_user struct, instead passing uninitialized data to mtd_regioninfo() 2. mtd_regioninfo() fails to utilize the 'regidx' parameter to fill out the regionindex parameter properly, so the garbage from mtdinfo.c is propagated to the ioctl() This means that mtdinfo will continuously probe the same (possibly out-of-range) erase region, instead of looping over the valid regions. Let's fix this in the mtd_regioninfo() helper, and at the same time, let's zero out the mtdinfo.c buffer, as an additional precaution to keep from using uninitialized data. Initial error report from Yang, when running "mtdinfo /dev/mtd0" on a Cavium 6100 board: root@CN61XX:~# mtdinfo /dev/mtd0 mtd0 Name: phys_mapped_flash Type: nor Eraseblock size: 65536 bytes, 64.0 KiB Amount of eraseblocks: 128 (8388608 bytes, 8.0 MiB) Minimum input/output unit size: 1 byte Sub-page size: 1 byte Additional erase regions: 0 Character device major/minor: 90:0 Bad blocks are allowed: false Device is writable: true libmtd: error!: MEMGETREGIONINFO ioctl failed for erase region 0 error 22 (Invalid argument) Eraseblock region 0: info is unavailable libmtd: error!: MEMGETREGIONINFO ioctl failed for erase region 1 error 22 (Invalid argument) Eraseblock region 1: info is unavailable Reported-by: Yang Wei <Wei.Yang@windriver.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>

2014-09-15libmtd: fix mtd_dev_present return value on legacy systemsGuido Martínez
On legacy systems, if "/proc/mtd" doesn't exist or gives a read error, mtd_dev_present returns -1 (since it calls legacy_dev_present), contrary to what's specified in the header file.

2014-05-30nandtest: Introduce multiple reads & check iterationsEzequiel García
The current nandtest performs a simple test which consists of: 1. erase block 2. write data 3. read and verify In order to improve the nandtest strength, this commit adds a new parameter to increase the number of "read and verify" iterations. In other words, the test now consists of: 1. erase block 2. write data 3. read and verify (N times) This seem to apply more pressure on a NAND driver's ECC engine and has been used to discover stability problems with an old OMAP2.
