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/um-x86_64-linux/bin/x86_64-linux-gcc --version # < git log --format=%s --max-count=1 5406812e59761f6ba33ea0bf97e426666bdb0e28 # < make -j 48 ARCH=um O=/home/kisskb/slave/build/linus_um-defconfig_um-x86_64 CROSS_COMPILE=/opt/cross/gcc-4.6.3-nolibc/um-x86_64-linux/bin/x86_64-linux- SUBARCH=x86_64 defconfig kernel/time/Kconfig:155:warning: range is invalid # make -j 48 ARCH=um O=/home/kisskb/slave/build/linus_um-defconfig_um-x86_64 CROSS_COMPILE=/opt/cross/gcc-4.6.3-nolibc/um-x86_64-linux/bin/x86_64-linux- SUBARCH=x86_64 make[1]: Entering directory '/home/kisskb/slave/build/linus_um-defconfig_um-x86_64' GEN ./Makefile scripts/kconfig/conf --silentoldconfig arch/x86/um/Kconfig kernel/time/Kconfig:155:warning: range is invalid CHK include/generated/uapi/linux/version.h UPD include/generated/uapi/linux/version.h HOSTCC scripts/basic/bin2c WRAP arch/um/include/generated/asm/barrier.h WRAP arch/um/include/generated/asm/bug.h WRAP arch/um/include/generated/asm/clkdev.h WRAP arch/um/include/generated/asm/cputime.h WRAP arch/um/include/generated/asm/current.h WRAP arch/um/include/generated/asm/delay.h WRAP arch/um/include/generated/asm/device.h WRAP arch/um/include/generated/asm/emergency-restart.h WRAP arch/um/include/generated/asm/exec.h WRAP arch/um/include/generated/asm/ftrace.h WRAP arch/um/include/generated/asm/futex.h WRAP arch/um/include/generated/asm/hardirq.h WRAP arch/um/include/generated/asm/hw_irq.h WRAP arch/um/include/generated/asm/io.h WRAP arch/um/include/generated/asm/irq_regs.h WRAP arch/um/include/generated/asm/irq_work.h WRAP arch/um/include/generated/asm/kdebug.h WRAP arch/um/include/generated/asm/mcs_spinlock.h WRAP arch/um/include/generated/asm/mm-arch-hooks.h WRAP arch/um/include/generated/asm/mutex.h WRAP arch/um/include/generated/asm/pci.h WRAP arch/um/include/generated/asm/param.h WRAP arch/um/include/generated/asm/preempt.h WRAP arch/um/include/generated/asm/switch_to.h WRAP arch/um/include/generated/asm/topology.h WRAP arch/um/include/generated/asm/trace_clock.h WRAP arch/um/include/generated/asm/word-at-a-time.h WRAP arch/um/include/generated/asm/xor.h WRAP arch/um/include/generated/asm/percpu.h CHK include/config/kernel.release GEN ./Makefile HOSTCC scripts/kallsyms CC scripts/mod/empty.o HOSTCC scripts/mod/mk_elfconfig CC scripts/mod/devicetable-offsets.s GEN scripts/mod/devicetable-offsets.h MKELF scripts/mod/elfconfig.h HOSTCC scripts/mod/modpost.o HOSTCC scripts/mod/file2alias.o HOSTCC scripts/mod/sumversion.o UPD include/config/kernel.release SYSTBL arch/x86/entry/syscalls/../../include/generated/asm/syscalls_32.h SYSHDR arch/x86/entry/syscalls/../../include/generated/asm/unistd_32_ia32.h SYSHDR arch/x86/entry/syscalls/../../include/generated/asm/unistd_64_x32.h SYSTBL arch/x86/entry/syscalls/../../include/generated/asm/syscalls_64.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 Using /home/kisskb/slave/src as source for kernel CHK include/generated/utsrelease.h UPD include/generated/utsrelease.h HOSTLD scripts/mod/modpost HOSTCC scripts/unifdef CC arch/x86/um/user-offsets.s In file included from /usr/include/features.h:374:0, from /usr/include/stdio.h:27, from /home/kisskb/slave/src/arch/x86/um/user-offsets.c:1: /opt/cross/gcc-4.6.3-nolibc/x86_64-linux/lib/gcc/x86_64-linux/4.6.3/../../../../x86_64-linux/include/sys/cdefs.h:385:27: fatal error: bits/wordsize.h: No such file or directory compilation terminated. /home/kisskb/slave/src/scripts/Makefile.build:153: recipe for target 'arch/x86/um/user-offsets.s' failed make[2]: *** [arch/x86/um/user-offsets.s] Error 1 arch/um/Makefile:150: recipe for target 'arch/x86/um/user-offsets.s' failed make[1]: *** [arch/x86/um/user-offsets.s] Error 2 make[1]: Leaving directory '/home/kisskb/slave/build/linus_um-defconfig_um-x86_64' Makefile:146: recipe for target 'sub-make' failed make: *** [sub-make] Error 2 Command 'make -j 48 ARCH=um O=/home/kisskb/slave/build/linus_um-defconfig_um-x86_64 CROSS_COMPILE=/opt/cross/gcc-4.6.3-nolibc/um-x86_64-linux/bin/x86_64-linux- SUBARCH=x86_64 ' returned non-zero exit status 2 # rm -rf /home/kisskb/slave/build/linus_um-defconfig_um-x86_64 # Build took: 0:00:05.788174
