2015-11-17libmtd: mtd_read: Take the buffer offset into account when readingMarcus Prebble
Assuming the read() call does not return zero and the result is less than len, the current implementation will overwrite the data already read in buf which doesn't seem correct. With this patch, subsequent calls to read() within the loop will now no longer overwrite the existing contents of buf.

2015-11-12flashcp: Use %llu to print filestat.st_sizeFabien Proriol
filestat.st_size type is off_t. For some paltforms, off_t can be 32 or 64bit but there is no C99 format specifier for off_t. The best way to print it with printf is to cast it to long long and print with %llu Signed-off-by: Fabien Proriol <fabien.proriol@jdsu.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>

2015-11-12mkfs.ubifs: Optionally create extended attribute with inode numberSascha Hauer
This is done to allow creating images suitable for IMA directory appraisal. IMA creates a hash for directories and attaches this hash to the directory itself as an extended attribute. Among other things the inode numbers of the files are hashed. So, to create a valid hash in the UBIFS image the evmctl tool needs to know the inode numbers which the files in the UBIFS image will have. evmctl will read the inode numbers from the user.image-inode-number extended attribute. Since extended attributes are inodes themselves the inode numbers for the generated image will change when the extended attributes change, so to generate a correctly hashed UBIFS image, both evmctl and mkfs.ubifs must be run twice: 1) execute evmctl to iterate over the directory tree. This will create the security.ima and security.evm extended attributes. The existence of the attributes makes sure that subsequent calls to mkfs.ubifs will use the same inode numbers. evmctl will use the inode numbers from the host filesystem in this step which makes the resulting image unusable 2) execute mkfs.ubifs -a. This will create the user.image-inode-number extended attributes on files/directories added to the image. 3) execture evmctl again. This time evmctl will pick the inode numbers from the user.image-inode-number extended attribute instead of the ones from the host filesystem 4) execute mkfs.ubifs again. This will create the correct image. The now existing user.image-inode-number extended attributes are ignored and not added to the image.

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>

2015-08-28autogenerated 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.
