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/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 353f7988dd8413c47718f7ca79c030b6fb62cfe5 # < make -s -j 120 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- sun3_defconfig arch/m68k/configs/sun3_defconfig:37:warning: symbol value 'm' invalid for ZPOOL # < make -s -j 120 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- help # make -s -j 120 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- olddefconfig # make -s -j 120 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- In file included from /kisskb/src/include/linux/string.h:20, from /kisskb/src/include/linux/bitmap.h:11, from /kisskb/src/include/linux/cpumask.h:12, from /kisskb/src/include/linux/mm_types_task.h:14, from /kisskb/src/include/linux/mm_types.h:5, from /kisskb/src/include/linux/buildid.h:5, from /kisskb/src/include/linux/module.h:14, from /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:32: In function 'check586', inlined from 'sun3_82586_probe1' at /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:365:6, inlined from 'sun3_82586_probe' at /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:311:8: /kisskb/src/arch/m68k/include/asm/string.h:68:25: warning: '__builtin_memset' offset [0, 11] is out of the bounds [0, 0] [-Warray-bounds] 68 \| #define memset(d, c, n) __builtin_memset(d, c, n) \| ^~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:218:9: note: in expansion of macro 'memset' 218 \| memset((char )p->scp,0, sizeof(struct scp_struct)); \| ^~~~~~ In file included from /kisskb/src/include/linux/swab.h:5, from /kisskb/src/include/uapi/linux/byteorder/big_endian.h:14, from /kisskb/src/include/linux/byteorder/big_endian.h:5, from /kisskb/src/arch/m68k/include/uapi/asm/byteorder.h:5, from /kisskb/src/include/asm-generic/bitops/le.h:6, from /kisskb/src/arch/m68k/include/asm/bitops.h:529, from /kisskb/src/include/linux/bitops.h:33, from /kisskb/src/include/linux/kernel.h:22, from /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:31: /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c: In function 'sun3_82586_timeout': /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:989:122: warning: array subscript 1 is above array bounds of 'volatile struct transmit_cmd_struct [1]' [-Warray-bounds] 989 \| printk("%s: command-stats: %04x %04x\n",dev->name,swab16(p->xmit_cmds[0]->cmd_status),swab16(p->xmit_cmds[1]->cmd_status)); \| ~~~~~~~~~~~~^~~ /kisskb/src/include/uapi/linux/swab.h:107:19: note: in definition of macro '__swab16' 107 \| __fswab16(x)) \| ^ /kisskb/src/include/linux/printk.h:464:26: note: in expansion of macro 'printk_index_wrap' 464 \| #define printk(fmt, ...) printk_index_wrap(_printk, fmt, ##__VA_ARGS__) \| ^~~~~~~~~~~~~~~~~ /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:989:17: note: in expansion of macro 'printk' 989 \| printk("%s: command-stats: %04x %04x\n",dev->name,swab16(p->xmit_cmds[0]->cmd_status),swab16(p->xmit_cmds[1]->cmd_status)); \| ^~~~~~ /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:155:46: note: while referencing 'xmit_cmds' 155 \| volatile struct transmit_cmd_struct xmit_cmds[NUM_XMIT_BUFFS]; \| ^~~~~~~~~ Completed OK # rm -rf /kisskb/build/linus_sun3_defconfig_m68k-gcc11 # Build took: 0:00:42.712224
