It turns out that squashfs can end up being confused about # negative fragment lengths. # # The regular squashfs_read_data() does check for negative lengths, but # squashfs_read_metadata() did not, and the fragment size code just # blindly trusted the on-disk value. Fix both the fragment parsing and # the metadata reading code. # # Reported-by: Anatoly Trosinenko <anatoly.trosinenko@gmail.com> # Cc: Al Viro <viro@zeniv.linux.org.uk> # Cc: Phillip Lougher <phillip@squashfs.org.uk> # Cc: stable@kernel.org # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc --version # < git log --format=%s --max-count=1 01cfb7937a9af2abb1136c7e89fbf3fd92952956 # < make -s -j 120 ARCH=arm O=/kisskb/build/linus_pxa3xx_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- pxa3xx_defconfig # make -s -j 120 ARCH=arm O=/kisskb/build/linus_pxa3xx_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- <stdin>:1332:2: warning: #warning syscall io_pgetevents not implemented [-Wcpp] /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:127:33: warning: 'levelspread[<U 1e0>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:94:6: note: 'levelspread[<U 1e0>]' was declared here /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:339:21: note: 'pdeo' was declared here Completed OK # rm -rf /kisskb/build/linus_pxa3xx_defconfig_arm # Build took: 0:00:17.592140
