2019-04-25unittests/libmtd_test: Include fcntl headerOlliver Schinagl
The test library for the mtd unit tests include various type's and macro's that officially live in fcntl. Each file and header should always properly include what they use, so lets add the fcntl headers.

2019-04-25unittests/test_lib: Include proper header for _IOC_SIZEOlliver Schinagl
The macro _IOC_SIZE is not part of sys/ioctl.h but lives in asm/ioctl.h so we should include the proper header. If we do not, some systems complain during linking that they cannot find the symbol _IOC_SIZE() which was not expanded by the pre-compiler.

2019-04-03mkfs.ubifs: fix regression when trying to store device special filesDavid Oberhollenzer
Commit a767dd30 added a check to add_inode that bails when trying to store extra data in anything other than a symlink. The symlink encryption support added by that commit relies on the assumption. Unfortionately it was overlooked that device special files also store the device number as additional data in the inode. The check added in commit a767dd30 broke support for device files in mkfs.ubifs. This commit adds a quick and dirty fix, moving the check into the fscrypt branch, breaking only the fscrypt version but restoring old functionality for unencrypted file systems.

2019-02-11mtd-utils: fixes double free in mkfs.ubifsYufen Yu
In inode_add_xattr(), it malloc a buffer for name, and then passes the bufffer ptr to add_xattr(). The ptr will be used to create a new idx_entry in add_to_index(). However, inode_add_xattr() will free the buffer before return. which can cause double free in write_index(): free(idx_ptr[i]->name) *** Error in `./mkfs.ubifs': double free or corruption (fasttop): 0x0000000000aae220 *** ======= Backtrace: ========= /lib64/libc.so.6(+0x7cbac)[0x7f4881ff5bac] /lib64/libc.so.6(+0x87a59)[0x7f4882000a59] /lib64/libc.so.6(cfree+0x16e)[0x7f48820063be] ./mkfs.ubifs[0x402fbf] /lib64/libc.so.6(__libc_start_main+0xea)[0x7f4881f9988a] ./mkfs.ubifs[0x40356a] Signed-off-by: Yufen Yu <yuyufen@huawei.com> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-01-25mtd-utils: avoid to create two UBI_LAYOUT_VOLUME_ID volumeYufen Yu
When we create a ubi image by ubinize, a UBI_LAYOUT_VOLUME_ID volume will be created by ubigen_write_layout_vol(). However, after the commit 4c00cf2c5816 (ubiformat: remove no-volume-table option), ubiformat remove novtbl args in format(). As a result, it will also create a layout volume.

UBIFS always knows how long a filename is, therefore we can change the hash function to iterate over the filename length to work correctly with binary strings.
