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
