Have the open functions there do the lockdown checks. # # - Fix a few races with opening an instance file and the instance # being deleted (Discovered during the lockdown updates). Kept # separate from the clean up code such that they can be backported to # stable easier. # # - Clean up and consolidated the checks done when opening a trace # file, as there were multiple checks that need to be done, and it # did not make sense having them done in each open instance. # # - Fix a regression in the record mcount code. # # - Small hw_lat detector tracer fixes. # # - A trace_pipe read fix due to not initializing trace_seq" # # * tag 'trace-v5.4-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: # tracing: Initialize iter->seq after zeroing in tracing_read_pipe() # tracing/hwlat: Don't ignore outer-loop duration when calculating max_latency # tracing/hwlat: Report total time spent in all NMIs during the sample # recordmcount: Fix nop_mcount() function # tracing: Do not create tracefs files if tracefs lockdown is in effect # tracing: Add locked_down checks to the open calls of files created for tracefs # tracing: Add tracing_check_open_get_tr() # tracing: Have trace events system open call tracing_open_generic_tr() # tracing: Get trace_array reference for available_tracers files # ftrace: Get a reference counter for the trace_array on filter files # tracefs: Revert ccbd54ff54e8 ("tracefs: Restrict tracefs when the kernel is locked down") # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 d4615e5a46800d2193bf8ae98cb470206f5f635b # < make -s -j 10 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 allmodconfig # 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 # yes \n | make -s -j 10 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 oldconfig yes: standard output: Broken pipe # make -s -j 10 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/arch/um/os-Linux/signal.c: In function 'sig_handler_common': /kisskb/src/arch/um/os-Linux/signal.c:51:1: warning: the frame size of 2976 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/arch/um/os-Linux/signal.c: In function 'timer_real_alarm_handler': /kisskb/src/arch/um/os-Linux/signal.c:95:1: warning: the frame size of 2960 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/security/apparmor/policy_unpack.c: In function 'unpack_profile': /kisskb/src/security/apparmor/policy_unpack.c:523:9: warning: 'pos' may be used uninitialized in this function [-Wmaybe-uninitialized] str[pos] = ':';
