2016-11-17nanddump: check write function result for errorsRafał Miłecki
Errors may happen, it's e.g. easy on embedded devices to run out of space when dumping big partitions. This patch adds a helper function for writing. It deals with partial writes and just returns 0 on success or error number. The old code didn't check for errors at all which could result in incomplete dumps without exiting with an error.

2016-08-25mtd-utils: mkfs.jffs2: initialize lzo decompression buffer sizeDavid Oberhollenzer
This fix was initialially part of a patch submitted by Carsten Schlote in January 2009. It didn't get merged back then because of coding style issues and a proposed buffer size change guessed by shotgun debugging. I was unable to reproduce the claimed segfaults in the compression function that lead to the proposed buffer size change. Valgrind did not issue any errors or warnings about the code in question either, so I didn't include the proposed buffer size change. The original patch also added a call to lzo_init(), which (according to LZO documentation & source code) does not actually perform any initialization, but only checks at runtime that the data type sizes and endianness of the library code match those in the caller code and should be unnecessary. Other fixes from the original patch have already been added over the years. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at> Signed-off-by: Richard Weinberger <richard@nod.at>
2016-08-25fs-tests: integrity: don't include header <bits/stdio_lim.h>Rahul Bedarkar
In commit ca7a5eda221d("integck.c: Fix buffer overflow in save_file") we started including header <bits/stdio_lim.h>. But with musl C library, we get following build error integck.c:37:28: fatal error: bits/stdio_lim.h: No such file or directory #include <bits/stdio_lim.h> ^ compilation terminated. make[2]: *** [integck] Error 1 Header <bits/stdio_lim.h> is not available in musl C library. However <stdio.h> has all definition that <bits/stdio_lim.h> supposed to be providing. Moreover <bits/stdio_lim.h> shouldn't be included directly instead we should be using <stdio.h>. Since we already include <stdio.h> and in case of uClibc or glibc <bits/stdio_lim.h> gets included internally, we can safely remove it.

The kernel refuses to read more data from a MTD device than the device size. However, mtd_debug does not check the amount of data read as returned by read(2) and assumes the requested amount is always read when there is no error.

2016-07-13libmtd: Fix return status in mtd_torture test functionDavid Oberhollenzer
This patch fixes the return status of the mtd_torture function in libmtd.

However, the way the function was written, it ALWAYS returns an error value regardless of whether it failed or not.

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.

Add new --lock/--unlock flags, so we can do either with the same binary.

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.
