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-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 5e46d1b78a03d52306f21f77a4e4a144b6d31486 # < make -s -j 8 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 8 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 8 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 8 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-objdump: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-objdump: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-objdump: mm/kfence/kfence_test.o: File format not recognized /kisskb/src/lib/bitfield_kunit.c: In function 'test_bitfields_constants': /kisskb/src/lib/bitfield_kunit.c:93:1: warning: the frame size of 7432 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info mm/kfence/kfence_test.o: file not recognized: File format not recognized make[3]: *** [/kisskb/src/scripts/Makefile.modfinal:78: mm/kfence/kfence_test.ko] Error 1 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [/kisskb/src/scripts/Makefile.modpost:138: __modpost] Error 2 make[1]: *** [/kisskb/src/Makefile:1442: modules] Error 2 make: *** [Makefile:215: __sub-make] Error 2 Command 'make -s -j 8 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 # Build took: 0:47:02.611448
