The bug fixes you already # have and much of the unprivileged fuse work is coming in via other # trees. # # Still left for fully unprivileged fuse is figuring out how to cleanly # handle .set_acl and .get_acl in the legacy case, and properly handling # of evm xattrs on unprivileged mounts. # # Included in the tree is a cleanup from Alexely that replaced a linked # list with a statically allocated fix sized array for the pid caches, # which simplifies and speeds things up. # # Then there is are some cleanups and fixes for the ipc namespace. The # motivation was that in reviewing other code it was discovered that # access ipc objects from different pid namespaces recorded pids in such # a way that when asked the wrong pids were returned. In the worst case # there has been a measured 30% performance impact for sysvipc # semaphores. Other test cases showed no measurable performance impact. # Manfred Spraul and Davidlohr Bueso who tend to work on sysvipc # performance both gave the nod that this is good enough. # # Casey Schaufler and James Morris have given their approval to the LSM # side of the changes. # # I simplified the types and the code dealing with sysvipc to pass just # kern_ipc_perm for all three types of ipc. Which reduced the header # dependencies throughout the kernel and simplified the lsm code. # # Which let me work on the pid fixes without having to worry about # trivial changes causing complete kernel recompiles" # # * 'userns-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: # ipc/shm: Fix pid freeing. # ipc/shm: fix up for struct file no longer being available in shm.h # ipc/smack: Tidy up from the change in type of the ipc security hooks # ipc: Directly call the security hook in ipc_ops.associate # ipc/sem: Fix semctl(..., GETPID, ...) between pid namespaces # ipc/msg: Fix msgctl(..., IPC_STAT, ...) between pid namespaces # ipc/shm: Fix shmctl(..., IPC_STAT, ...) between pid namespaces. # ipc/util: Helpers for making the sysvipc operations pid namespace aware # ipc: Move IPCMNI from include/ipc.h into ipc/util.h # msg: Move struct msg_queue into ipc/msg.c # shm: Move struct shmid_kernel into ipc/shm.c # sem: Move struct sem and struct sem_array into ipc/sem.c # msg/security: Pass kern_ipc_perm not msg_queue into the msg_queue security hooks # shm/security: Pass kern_ipc_perm not shmid_kernel into the shm security hooks # sem/security: Pass kern_ipc_perm not sem_array into the sem security hooks # pidns: simpler allocation of pid_* caches # < /opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc-gcc --version # < git log --format=%s --max-count=1 17dec0a949153d9ac00760ba2f5b78cb583e995f # < make -s -j 10 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- axs101_defconfig # Added to kconfig CONFIG_INITRAMFS_SOURCE="" # yes \n | make -s -j 10 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 10 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- In file included from /kisskb/src/include/asm-generic/bug.h:18:0, from /kisskb/src/arch/arc/include/asm/bug.h:32, from /kisskb/src/include/linux/bug.h:5, from /kisskb/src/include/linux/mmdebug.h:5, from /kisskb/src/include/linux/gfp.h:5, from /kisskb/src/include/linux/slab.h:15, from /kisskb/src/mm/nobootmem.c:14: /kisskb/src/mm/nobootmem.c: In function '__free_pages_memory': /kisskb/src/include/linux/kernel.h:793:16: warning: comparison of distinct pointer types lacks a cast [enabled by default] (void) (&min1 == &min2); \ ^ /kisskb/src/include/linux/kernel.h:802:2: note: in expansion of macro '__min' __min(typeof(x), typeof(y), \ ^ /kisskb/src/mm/nobootmem.c:104:11: note: in expansion of macro 'min' order = min(MAX_ORDER - 1UL, __ffs(start)); ^ /kisskb/src/net/ipv4/tcp_input.c: In function 'tcp_data_queue': /kisskb/src/net/ipv4/tcp_input.c:4240:49: warning: array subscript is above array bounds [-Warray-bounds] tp->selective_acks[i-1] = tp->selective_acks[i]; ^ /kisskb/src/net/xfrm/xfrm_policy.c: In function '__xfrm_policy_check': /kisskb/src/net/xfrm/xfrm_policy.c:2378:15: warning: array subscript is above array bounds [-Warray-bounds] if (sp->xvec[k]->props.mode != XFRM_MODE_TRANSPORT) { ^ Completed OK # rm -rf /kisskb/build/linus_axs101_defconfig_arcompact # Build took: 0:01:03.010181
