The issues were found when testing # the ongoing changes introducing atomic consoles and printk kthreads: # # - pr_flush() has to wait for the last reserved record instead of the # last finalized one. Note that records are finalized in random order # when generated by more CPUs in parallel. # # - Ignore non-finalized records during panic(). Messages printed on # panic-CPU are always finalized. Messages printed by other CPUs # might never be finalized when the CPUs get stopped. # # - Block new printk() calls on non-panic CPUs completely. Backtraces # are printed before entering the panic mode. Later messages would # just mess information printed by the panic CPU. # # - Do not take console_lock in console_flush_on_panic() at all. The # original code did try_lock()/console_unlock(). The unlock part # might cause a deadlock when panic() happened in a scheduler code. # # - Fix conversion of 64-bit sequence number for 32-bit atomic # operations" # # * tag 'printk-for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: # dump_stack: Do not get cpu_sync for panic CPU # panic: Flush kernel log buffer at the end # printk: Avoid non-panic CPUs writing to ringbuffer # printk: Disable passing console lock owner completely during panic() # printk: ringbuffer: Skip non-finalized records in panic # printk: Wait for all reserved records with pr_flush() # printk: ringbuffer: Cleanup reader terminology # printk: Add this_cpu_in_panic() # printk: For @suppress_panic_printk check for other CPU in panic # printk: ringbuffer: Clarify special lpos values # printk: ringbuffer: Do not skip non-finalized records with prb_next_seq() # printk: Use prb_first_seq() as base for 32bit seq macros # printk: Adjust mapping for 32bit seq macros # printk: nbcon: Relocate 32bit seq macros # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 b0546776ad3f332e215cebc0b063ba4351971cca # make -s -j 40 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 allyesconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig CONFIG_BPF_PRELOAD=n # Added to kconfig CONFIG_SPI_STM32_QSPI=n # < make -s -j 40 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 help # make -s -j 40 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 olddefconfig .config:14405:warning: override: reassigning to symbol GCC_PLUGIN_LATENT_ENTROPY .config:14409:warning: override: reassigning to symbol UML_NET_ETHERTAP .config:14411:warning: override: reassigning to symbol UML_NET_SLIP .config:14416:warning: override: reassigning to symbol UML_NET_SLIRP # make -s -j 40 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/arch/x86/um/user-offsets.c:17:6: warning: no previous prototype for ‘foo’ [-Wmissing-prototypes] 17 | void foo(void) | ^~~ In file included from /kisskb/src/arch/um/kernel/asm-offsets.c:1: /kisskb/src/arch/x86/um/shared/sysdep/kernel-offsets.h:9:6: error: no previous prototype for ‘foo’ [-Werror=missing-prototypes] 9 | void foo(void) | ^~~ cc1: all warnings being treated as errors make[3]: *** [/kisskb/src/scripts/Makefile.build:116: arch/um/kernel/asm-offsets.s] Error 1 make[2]: *** [/kisskb/src/Makefile:1199: prepare0] Error 2 make[1]: *** [/kisskb/src/Makefile:240: __sub-make] Error 2 make: *** [Makefile:240: __sub-make] Error 2 Command 'make -s -j 40 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 ' returned non-zero exit status 2. # rm -rf /kisskb/build/linus_allyesconfig_um-x86_64-gcc12 # Build took: 0:00:17.989284
