However, while that is protected by the # watchqueue lock, new watchqueue entries aren't actually added under that # lock at all: they use the pipe->rd_wait.lock instead, and looking up # that pipe happens without any locking. # # The watchqueue code uses the RCU read-side section to make sure that the # wqueue entry itself hasn't disappeared, but that does not protect the # pipe_info in any way. # # So make sure to actually hold the wqueue lock when posting watch events, # properly serializing against the pipe being torn down. # # Reported-by: Noam Rathaus <noamr@ssd-disclosure.com> # Cc: Greg KH <gregkh@linuxfoundation.org> # Cc: David Howells <dhowells@redhat.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/riscv64-linux/bin/riscv64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/riscv64-linux/bin/riscv64-linux-ld --version # < git log --format=%s --max-count=1 353f7988dd8413c47718f7ca79c030b6fb62cfe5 # < make -s -j 32 ARCH=riscv O=/kisskb/build/linus_riscv-defconfig_riscv-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/riscv64-linux/bin/riscv64-linux- defconfig # < make -s -j 32 ARCH=riscv O=/kisskb/build/linus_riscv-defconfig_riscv-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/riscv64-linux/bin/riscv64-linux- help # make -s -j 32 ARCH=riscv O=/kisskb/build/linus_riscv-defconfig_riscv-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/riscv64-linux/bin/riscv64-linux- olddefconfig # make -s -j 32 ARCH=riscv O=/kisskb/build/linus_riscv-defconfig_riscv-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/riscv64-linux/bin/riscv64-linux- Completed OK # rm -rf /kisskb/build/linus_riscv-defconfig_riscv-gcc11 # Build took: 0:02:47.363632
