The kernel returns with inconsistent state # which can in the worst case result in a UAF of a tasks kernel # stack. # # The solution is to establish consistent kernel state which makes # future operations on the futex fail because user space and kernel # space state are inconsistent. Not a problem as PI futexes # fundamentaly require a functional RW mapping and if user space # pulls the rug under it, then it can keep the pieces it asked for. # # - Address an issue where the return value is incorrect in case that # the futex was acquired after a timeout/signal made the waiter drop # out of the rtmutex wait. # # In one of the corner cases the kernel returned an error code # despite having successfully acquired the futex" # # * tag 'locking-urgent-2021-01-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # futex: Handle faults correctly for PI futexes # futex: Simplify fixup_pi_state_owner() # futex: Use pi_state_update_owner() in put_pi_state() # rtmutex: Remove unused argument from rt_mutex_proxy_unlock() # futex: Provide and use pi_state_update_owner() # futex: Replace pointless printk in fixup_owner() # futex: Ensure the correct return value from futex_lock_pi() # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 c64396cc36c6e60704ab06c1fb1c4a46179c9120 # < make -s -j 10 ARCH=powerpc O=/kisskb/build/linus_mpc83xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc83xx_defconfig # < make -s -j 10 ARCH=powerpc O=/kisskb/build/linus_mpc83xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 10 ARCH=powerpc O=/kisskb/build/linus_mpc83xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 10 ARCH=powerpc O=/kisskb/build/linus_mpc83xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/block/genhd.c: In function 'diskstats_show': /kisskb/src/block/genhd.c:1520:1: warning: the frame size of 1160 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ INFO: Uncompressed kernel (size 0x7e49c4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e49c4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e49c4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e49c4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e49c4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e49c4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e49c4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7d43b4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) Image Name: Linux-5.11.0-rc5-gc64396cc36c6 Created: Fri Jan 29 09:34:18 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3593707 Bytes = 3509.48 KiB = 3.43 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.11.0-rc5-gc64396cc36c6 Created: Fri Jan 29 09:34:18 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3625135 Bytes = 3540.17 KiB = 3.46 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.11.0-rc5-gc64396cc36c6 Created: Fri Jan 29 09:34:18 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3623918 Bytes = 3538.98 KiB = 3.46 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.11.0-rc5-gc64396cc36c6 Created: Fri Jan 29 09:34:18 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3624756 Bytes = 3539.80 KiB = 3.46 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.11.0-rc5-gc64396cc36c6 Created: Fri Jan 29 09:34:18 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3623705 Bytes = 3538.77 KiB = 3.46 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.11.0-rc5-gc64396cc36c6 Created: Fri Jan 29 09:34:18 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3624697 Bytes = 3539.74 KiB = 3.46 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.11.0-rc5-gc64396cc36c6 Created: Fri Jan 29 09:34:18 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3624731 Bytes = 3539.78 KiB = 3.46 MiB Load Address: 00800000 Entry Point: 00800294 Completed OK # rm -rf /kisskb/build/linus_mpc83xx_defconfig_powerpc-gcc4.9 # Build took: 0:01:11.302729
