The xattr root doesn't exist, so we get # an oops. # # Therefore, update reiserfs_xattrs_initialized() to check both the # privroot and the xattr root. # # Link: https://syzkaller.appspot.com/bug?id=8abaedbdeb32c861dc5340544284167dd0e46cde # [1] # Reported-and-tested-by: syzbot <syzbot+690cb1e51970435f9775@syzkaller.appspotmail.com> # Signed-off-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> # Fixes: 6cb4aff0a77c ("reiserfs: fix oops while creating privroot with selinux enabled") # Acked-by: Jeff Mahoney <jeffm@suse.com> # Acked-by: Jan Kara <jack@suse.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 5e46d1b78a03d52306f21f77a4e4a144b6d31486 # < make -s -j 10 ARCH=sh O=/kisskb/build/linus_sh7785lcr_32bit_defconfig_sh4-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux- sh7785lcr_32bit_defconfig # < make -s -j 10 ARCH=sh O=/kisskb/build/linus_sh7785lcr_32bit_defconfig_sh4-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 10 ARCH=sh O=/kisskb/build/linus_sh7785lcr_32bit_defconfig_sh4-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 10 ARCH=sh O=/kisskb/build/linus_sh7785lcr_32bit_defconfig_sh4-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h sh4-linux-gcc: error: command line option '-m4-nofpu' is not supported by this configuration sh4-linux-gcc: error: command line option '-m4-nofpu' is not supported by this configuration make[2]: * [/kisskb/src/scripts/Makefile.build:271: scripts/mod/empty.o] Error 1 make[2]: * Waiting for unfinished jobs.... sh4-linux-gcc: error: command line option '-m4-nofpu' is not supported by this configuration sh4-linux-gcc: error: command line option '-m4-nofpu' is not supported by this configuration make[2]: * [/kisskb/src/scripts/Makefile.build:116: scripts/mod/devicetable-offsets.s] Error 1 make[1]: * [/kisskb/src/Makefile:1234: prepare0] Error 2 make: *** [Makefile:215: __sub-make] Error 2 Command 'make -s -j 10 ARCH=sh O=/kisskb/build/linus_sh7785lcr_32bit_defconfig_sh4-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_sh7785lcr_32bit_defconfig_sh4-gcc4.9 # Build took: 0:00:05.382634
