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. When we attempt to do ubiattach, it will fail for ubi_compare_lebs error: ubi0 error: ubi_compare_lebs: unsupported on-flash UBI format ubi0 error: ubi_attach_mtd_dev: failed to attach mtd1, error -22 Signed-off-by: Yufen Yu <yuyufen@huawei.com> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2018-11-01mkfs.ubifs: Make r5 hash binary string awareRichard Weinberger
As of now all filenames known by UBIFS are strings with a NUL terminator. With encrypted filenames a filename can be any binary string and the r5 function cannot search for the NUL terminator. 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.
