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-8.1.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 c64396cc36c6e60704ab06c1fb1c4a46179c9120 # < make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- defconfig # < make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- FIT description: Linux 5.11.0-rc5-gc64396cc36c6 Created: Fri Jan 29 11:12:13 2021 Image 0 (kernel@0) Description: Linux 5.11.0-rc5-gc64396cc36c6 Created: Fri Jan 29 11:12:13 2021 Type: Kernel Image Compression: gzip compressed Data Size: 5191536 Bytes = 5069.86 KiB = 4.95 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x809914ac Hash algo: sha1 Hash value: 9b198d336792fccf1e40542c4138427fa3c3ba92 Image 1 (fdt@boston) Description: img,boston Device Tree Created: Fri Jan 29 11:12:13 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 3793 Bytes = 3.70 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 4799f50d688573234da6e9d7701234d394759ef4 Image 2 (fdt@ni169445) Description: NI 169445 device tree Created: Fri Jan 29 11:12:13 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 1871 Bytes = 1.83 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 51b89b31605ee62038c8468c429af091dfc75ec7 Image 3 (fdt@ocelot_pcb123) Description: MSCC Ocelot PCB123 Device Tree Created: Fri Jan 29 11:12:13 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 4659 Bytes = 4.55 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 5bcb6e4f21e8e5372544aa130b3bd097355a9050 Image 4 (fdt@ocelot_pcb120) Description: MSCC Ocelot PCB120 Device Tree Created: Fri Jan 29 11:12:13 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 5418 Bytes = 5.29 KiB = 0.01 MiB Architecture: MIPS Hash algo: sha1 Hash value: 93d882f2009a217e0fa9dab94788535ed2be8476 Image 5 (fdt@xilfpga) Description: MIPSfpga (xilfpga) Device Tree Created: Fri Jan 29 11:12:13 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 2708 Bytes = 2.64 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 63d058b780f65e22da30f0a183433765f1807f1d Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Configuration 1 (conf@boston) Description: Boston Linux kernel Kernel: kernel@0 FDT: fdt@boston Configuration 2 (conf@ni169445) Description: NI 169445 Linux Kernel Kernel: kernel@0 FDT: fdt@ni169445 Configuration 3 (conf@ocelot_pcb123) Description: Ocelot Linux kernel Kernel: kernel@0 FDT: fdt@ocelot_pcb123 Configuration 4 (conf@ocelot_pcb120) Description: Ocelot Linux kernel Kernel: kernel@0 FDT: fdt@ocelot_pcb120 Configuration 5 (conf@xilfpga) Description: MIPSfpga Linux kernel Kernel: kernel@0 FDT: fdt@xilfpga Completed OK # rm -rf /kisskb/build/linus_mips-defconfig_mips-gcc8 # Build took: 0:03:02.985208
