And as a result the # error doesn't go through our 'fault_signal_pending()' logic, and doesn't # get filtered away there. # # Normally you'd never even notice, because if a fatal signal is pending, # the new SIGSEGV we send ends up being ignored anyway. # # But it turns out that there is one very noticeable exception: if you # enable 'show_unhandled_signals', the aborted page fault will be logged # in the kernel messages, and you'll get a scary line looking something # like this in your logs: # # pverados[2183248]: segfault at 55e5a00f9ae0 ip 000055e5a00f9ae0 sp 00007ffc0720bea8 error 14 in perl[55e5a00d4000+195000] likely on CPU 10 (core 4, socket 0) # # which is rather misleading. It's not really a segfault at all, it's # just "the thread was killed before the page fault completed, so we # aborted the page fault". # # Fix this by just making it clear that a pending fatal signal means that # any new signal coming in after that is implicitly handled. This will # avoid the misleading logging, since now the signal isn't 'unhandled' any # more. # # Reported-and-tested-by: Fiona Ebner <f.ebner@proxmox.com> # Tested-by: Thomas Lamprecht <t.lamprecht@proxmox.com> # Link: https://lore.kernel.org/lkml/8d063a26-43f5-0bb7-3203-c6a04dc159f8@proxmox.com/ # Acked-by: Oleg Nesterov <oleg@redhat.com> # Fixes: eda0047296a1 ("mm: make the page fault mmap locking killable") # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 5f0bc0b042fc77ff70e14c790abdec960cde4ec1 # make -s -j 32 ARCH=mips O=/kisskb/build/linus-rand_allmodconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MIPS_CPS_NS16550_BASE=0x1b0003f8 # Added to kconfig CONFIG_MIPS_CPS_NS16550_SHIFT=0 # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig # < make -s -j 32 ARCH=mips O=/kisskb/build/linus-rand_allmodconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 32 ARCH=mips O=/kisskb/build/linus-rand_allmodconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- olddefconfig .config:14504:warning: override: reassigning to symbol MIPS_CPS_NS16550_SHIFT # make -s -j 32 ARCH=mips O=/kisskb/build/linus-rand_allmodconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- In file included from /kisskb/src/include/linux/string.h:254, from /kisskb/src/include/linux/bitmap.h:11, from /kisskb/src/include/linux/cpumask.h:12, from /kisskb/src/include/linux/smp.h:13, from /kisskb/src/arch/mips/include/asm/cpu-type.h:12, from /kisskb/src/arch/mips/include/asm/timex.h:19, from /kisskb/src/include/linux/timex.h:67, from /kisskb/src/include/linux/time32.h:13, from /kisskb/src/include/linux/time.h:60, from /kisskb/src/include/linux/stat.h:19, from /kisskb/src/include/linux/module.h:13, from /kisskb/src/drivers/net/wireless/legacy/ray_cs.c:20: In function 'fortify_memset_chk', inlined from 'memset_io' at /kisskb/src/arch/mips/include/asm/io.h:486:2, inlined from 'build_auth_frame' at /kisskb/src/drivers/net/wireless/legacy/ray_cs.c:2697:2: /kisskb/src/include/linux/fortify-string.h:493:25: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()?
