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/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 01cfb7937a9af2abb1136c7e89fbf3fd92952956 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_ppc40x_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc40x_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_ppc40x_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /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 /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:251:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:231:19: note: 'i' was declared here INFO: Uncompressed kernel (size 0x50f780) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x50f780) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x50f780) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x4ff10c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x50f780) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-4.18.0-rc6-g01cfb79 Created: Mon Jul 30 06:05:20 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2528690 Bytes = 2469.42 kB = 2.41 MB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.18.0-rc6-g01cfb79 Created: Mon Jul 30 06:05:20 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2556166 Bytes = 2496.26 kB = 2.44 MB Load Address: 00600000 Entry Point: 00601534 Image Name: Linux-4.18.0-rc6-g01cfb79 Created: Mon Jul 30 06:05:20 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2555413 Bytes = 2495.52 kB = 2.44 MB Load Address: 00600000 Entry Point: 00601350 Completed OK # rm -rf /kisskb/build/linus_ppc40x_defconfig_powerpc # Build took: 0:00:46.938703
