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. This causes checks like if (mtd_dev_present(n)) { ... } to give false positives. Fix this by comparing the return value to 1.

2014-09-08nandtest: fix --reads argumentGuido Martínez
The --reads option specifies the argument as optional, but doesn't check for a null optarg, which means that nandtest segfaults when run as "nandtest --reads". Fix this by making the argument required, and changing the help text to not specify it as optional. Argument -r already specifies the argument as required, so we fix this inconsistency too.

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.

An implementation of rpmatch() was backported to the 0.9.33 branch of uClibc.

The 'make_a_release.sh' script appears to be extremely useful - I do not forget things as I used to anymore (amending Makefile, signing, uploading to the FTP server, etc). It is very useful that it suggest me exact commands which I may just copy-past to my command line.

The build rule for mkfs.ubifs was missing an LDFLAGS_* variable like mkfs.jffs2 had.

2013-10-24flash_erase: check the nand typeHuang Shijie
Now, the MTD_NANDFLASH stands for SLC nand, and the MTD_MLCNANDFLASH stands for the MLC nand. This patch includes the stdbool.h, and changes the "isNAND" to boolean type, and checks the right nand type for the MLC and SLC nand.

2013-10-22check the MLC nand typeHuang Shijie
In the current code, the MTD_NANDFLASH stands for both the SLC and MLC.

2013-07-01ubiupdatevol: add a --skip optionMike Frysinger
This already has a --size option for controlling how many bytes to read from the input. Add a --skip option to control the offset into the input too. This way people don't have to do `dd | ubiupdatevol`. While we're here, I've fixed the types used with args.size and the read loop so that they can hold the right sizes (like setting a 32bit+ size).

2013-07-01nandwrite: add --input-{skip,size} optionsMike Frysinger
If you have a file image and want to copy sub-portions out and into NAND, there's no easy way to do that. You can use dd to extract it to a temp file, or pipe it to nandwrite 1 page at a time. Both suck. Add two new flags to explicitly set the size and offset of the input file. Seeking stdin isn't currently supported as I'm not sure it's necessary. It wouldn't be hard to add though...

2013-07-01nandwrite: clean up length typesMike Frysinger
We use 'int' in many places to represent offsets/sizes. That obviously does not play well with larger NAND devices on 32bit systems. Instead, use the right type as needed: - long long to represent the length of the image - use fstat() rather than lseek();lseek(); to get the length of the image - use size_t/ssize_t when working with read() - tweak the printf formats as needed Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

2013-07-01move _GNU_SOURCE to the main makefileMike Frysinger
A bunch of utils are relying on _GNU_SOURCE already. The new prompt code uses getline() which is now part of POSIX, but in older versions of glibc, it was behind _GNU_SOURCE as it was a GNU extension. This change doesn't actually tie us to glibc. Only code that uses GNU extensions does that. It just kills warning when using older versions of glibc.

2013-03-11integck.c: Fix buffer overflow in save_fileElie De Brauwer
In the problem above I've spend several hours waiting for the issue to appear, only to had the 'luck' that it was found in a file whose name was 256 bytes in length, resulting in the write to fail. Closer examination showed that the buffer to store the path was 256 bytes in length, but this buffer also includes /tmp and the read/write suffix and should be able to contain a filename which is up to 255 bytes (NAME_MAX in linux/limits.h) in size which is a bad fit. So that array is modified to FILENAME_MAX (stdio_lim.h) and some checking is added to truncate the filename should it cause an overflow. The following log shows the first patch in action (see the correct seed), and shows why this third patch is needed: <quote> integck:     File Data: integck:         Offset: 0  Size: 1  Seed: 5008310  R.Off: 0 integck:     1 writes integck:     ============================================ integck:     Write Info: integck:         Offset: 0  Size: 1  Seed: 5008310  R.Off: 0 integck:         Offset: 0  Size: 1  Seed: 8246352  R.Off: 0 integck:         Offset: 0  Size: 1  Seed: 5078796  R.Off: 0 integck:         Offset: 0  Size: 1  Seed: 2267087  R.Off: 0 integck:         Offset: 0  Size: 1  Seed: 3602680  R.Off: 0 integck:     5 writes or truncations integck:     ============================================ integck: Saving /tmp/yqcnfygfitaatyeyvffrguegcdttamcnyhowhgieljfuxfipiljsjcbluaeaghwyinkggommsbwnmvekihgnwgiibccpbwfrpxuxwkmnyghnutrudienngxwgorudbskedaaekiuiyqksfazrwzfwbfhzjjqoiulebtlpbfiuffmsnguqkjzqjqizimsmhbqqagaebjdhqwmzdxghiavtcxubegawlgtvstuqurkurpnrckjfkgostdtpg.integ.sav.readn integck: error!: condition 'w_fd != -1' failed in save_file() at integck.c:1445 integck: error 36 (File name too long) </quote> Signed-off-by: Elie De Brauwer <eliedebrauwer@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

the errors See my problem description int the previous commit, the point is that integck in file_check_data reads a buffer, and then checks if the data is correct,  it will do a seek(0), and reread from the same fd.

Clearly it is not there (which is already extremely confusing). The point is that file_write_info first updates the raw_write, then verifies the data (passing the new write) and only after that updates the write structure. But in file_check_data only the newly written data is verified (passed as an argument) whilst the save_file() function to dump the file uses the raw_writes to recreate the written data (while raw_writes is only updated after after this check would have succeeded). Several lines to say that in this patch the verify only gets called _after_ the datastructures are updated.
