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 # Cc: Greg KH # Cc: David Howells # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 353f7988dd8413c47718f7ca79c030b6fb62cfe5 # < make -s -j 120 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_64BIT=n # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_HAVE_FTRACE_MCOUNT_RECORD=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 120 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux- help # make -s -j 120 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux- olddefconfig # make -s -j 120 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux- :1517:2: warning: #warning syscall clone3 not implemented [-Wcpp] WARNING: modpost: EXPORT symbol "empty_zero_page" [vmlinux] version generation failed, symbol will not be versioned.
