The pids controller and the changes made to cgroup core to support it introduced and revealed several important issues. - Assigning membership to a newly created task and migrating it can race leading to incorrect accounting. Oleg fixed it by widening threadgroup synchronization. It looks like we'll be able to merge it with a different percpu rwsem which is used in fork path making things simpler and cheaper. - The recent change to extend cgroup membership to zombies (so that pid accounting can extend till the pid is actually released) missed pinning the underlying data structures leading to use-after-free. Fixed. - v2 hierarchy was calling subsystem callbacks with the wrong target cgroup_subsys_state based on the incorrect assumption that they share the same target. pids is the first controller affected by this. Subsys callbacks updated so that they can deal with multi-target migrations" * 'for-4.4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroup_pids: don't account for the root cgroup cgroup: fix handling of multi-destination migration from subtree_control enabling cgroup_freezer: simplify propagation of CGROUP_FROZEN clearing in freezer_attach() cgroup: pids: kill pids_fork(), simplify pids_can_fork() and pids_cancel_fork() cgroup: pids: fix race between cgroup_post_fork() and cgroup_migrate() cgroup: make css_set pin its css's to avoid use-afer-free cgroup: fix cftype->file_offset handling # < /opt/cross/gcc-4.6.3-nolibc/i386-linux/bin/i386-linux-gcc --version # < git log --format=%s --max-count=1 5406812e59761f6ba33ea0bf97e426666bdb0e28 # < make -j 8 ARCH=i386 O=/home/kisskb/slave/build/linus_i386-randconfig_i386 CROSS_COMPILE=/opt/cross/gcc-4.6.3-nolibc/i386-linux/bin/i386-linux- randconfig KCONFIG_SEED=0xA07D2937 # Added to kconfig CONFIG_STANDALONE=y # yes \n | make -j 8 ARCH=i386 O=/home/kisskb/slave/build/linus_i386-randconfig_i386 CROSS_COMPILE=/opt/cross/gcc-4.6.3-nolibc/i386-linux/bin/i386-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -j 8 ARCH=i386 O=/home/kisskb/slave/build/linus_i386-randconfig_i386 CROSS_COMPILE=/opt/cross/gcc-4.6.3-nolibc/i386-linux/bin/i386-linux- make[1]: Entering directory '/home/kisskb/slave/build/linus_i386-randconfig_i386' GEN ./Makefile scripts/kconfig/conf --silentoldconfig Kconfig arch/x86/Makefile:133: stack-protector enabled but compiler support broken /home/kisskb/slave/src/Makefile:660: Cannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong not supported by compiler SYSTBL arch/x86/entry/syscalls/../../include/generated/asm/syscalls_32.h SYSHDR arch/x86/entry/syscalls/../../include/generated/uapi/asm/unistd_32.h SYSHDR arch/x86/entry/syscalls/../../include/generated/uapi/asm/unistd_64.h SYSHDR arch/x86/entry/syscalls/../../include/generated/uapi/asm/unistd_x32.h HOSTCC scripts/basic/bin2c CHK include/config/kernel.release UPD include/config/kernel.release GEN ./Makefile WRAP arch/x86/include/generated/asm/mm-arch-hooks.h WRAP arch/x86/include/generated/asm/mcs_spinlock.h WRAP arch/x86/include/generated/asm/early_ioremap.h WRAP arch/x86/include/generated/asm/clkdev.h WRAP arch/x86/include/generated/asm/cputime.h WRAP arch/x86/include/generated/asm/dma-contiguous.h CHK include/generated/uapi/linux/version.h UPD include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h UPD include/generated/utsrelease.h HOSTCC scripts/sortextable HOSTCC scripts/kallsyms HOSTCC scripts/conmakehash HOSTCC scripts/dtc/dtc.o CC scripts/mod/empty.o cc1: error: unrecognized command line option '-fstack-protector-strong' /home/kisskb/slave/src/scripts/Makefile.build:258: recipe for target 'scripts/mod/empty.o' failed make[3]: *** [scripts/mod/empty.o] Error 1 /home/kisskb/slave/src/scripts/Makefile.build:403: recipe for target 'scripts/mod' failed make[2]: *** [scripts/mod] Error 2 make[2]: *** Waiting for unfinished jobs....
