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-8.5.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 353f7988dd8413c47718f7ca79c030b6fb62cfe5 # < make -s -j 32 ARCH=m68k O=/kisskb/build/linus_m68k-allmodconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-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 32 ARCH=m68k O=/kisskb/build/linus_m68k-allmodconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux- help # make -s -j 32 ARCH=m68k O=/kisskb/build/linus_m68k-allmodconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux- olddefconfig # make -s -j 32 ARCH=m68k O=/kisskb/build/linus_m68k-allmodconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux- In file included from /kisskb/src/include/linux/bitops.h:33, from /kisskb/src/include/linux/thread_info.h:27, from /kisskb/src/include/asm-generic/preempt.h:5, from ./arch/m68k/include/generated/asm/preempt.h:1, from /kisskb/src/include/linux/preempt.h:78, from /kisskb/src/arch/m68k/include/asm/irqflags.h:6, from /kisskb/src/include/linux/irqflags.h:16, from /kisskb/src/arch/m68k/include/asm/atomic.h:6, from /kisskb/src/include/linux/atomic.h:7, from /kisskb/src/include/linux/rcupdate.h:25, from /kisskb/src/include/linux/rculist.h:11, from /kisskb/src/include/linux/pid.h:5, from /kisskb/src/include/linux/sched.h:14, from /kisskb/src/include/linux/ratelimit.h:6, from /kisskb/src/include/linux/dev_printk.h:16, from /kisskb/src/include/linux/device.h:15, from /kisskb/src/include/linux/dma-mapping.h:7, from /kisskb/src/drivers/net/ipa/ipa_mem.c:10: /kisskb/src/drivers/net/ipa/ipa_mem.c: In function 'ipa_mem_init': /kisskb/src/arch/m68k/include/asm/bitops.h:329:20: error: array subscript 2 is above array bounds of 'long unsigned int[1]' [-Werror=array-bounds] while (!(num = ~p++)) { ~^~ cc1: all warnings being treated as errors make[4]: [/kisskb/src/scripts/Makefile.build:249: drivers/net/ipa/ipa_mem.o] Error 1 make[3]: * [/kisskb/src/scripts/Makefile.build:466: drivers/net/ipa] Error 2 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/scripts/Makefile.build:466: drivers/net] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1843: drivers] Error 2 make[1]: * Waiting for unfinished jobs.... make: * [Makefile:219: __sub-make] Error 2 Command 'make -s -j 32 ARCH=m68k O=/kisskb/build/linus_m68k-allmodconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_m68k-allmodconfig_m68k-gcc8 # Build took: 0:07:20.091633
