2011-05-28Cache xattr security drop check for write v2Andi Kleen
Some recent benchmarking on btrfs showed that a major scaling bottleneck on large systems on btrfs is currently the xattr lookup on every write. Why xattr lookup on every write I hear you ask? write wants to drop suid and security related xattrs that could set o capabilities for executables. To do that it currently looks up security.capability on EVERY write (even for non executables) to decide whether to drop it or not. In btrfs this causes an additional tree walk, hitting some per file system locks and quite bad scalability. In a simple read workload on a 8S system I saw over 90% CPU time in spinlocks related to that. Chris Mason tells me this is also a problem in ext4, where it hits the global mbcache lock. This patch adds a simple per inode to avoid this problem. We only do the lookup once per file and then if there is no xattr cache the decision. All xattr changes clear the flag. I also used the same flag to avoid the suid check, although that one is pretty cheap. A file system can also set this flag when it creates the inode, if it has a cheap way to do so. This is done for some common file systems in followon patches. With this patch a major part of the lock contention disappears for btrfs. Some testing on smaller systems didn't show significant performance changes, but at least it helps the larger systems and is generally more efficient. v2: Rename is_sgid. add file system helper.

2011-05-27NFS: Revert NFSROOT default mount optionsChuck Lever

An examination of a network trace captured during the failure shows that the mount is actually succeeding, but that the client is not seeing READ replies larger than 16KB. This could be a local packet filtering issue on the client, but we didn't troubleshoot this further because of the reported "git bisect" result. Last fall we removed the ad hoc mount option parser in fs/nfs/nfsroot.c in favor of using the main parser in fs/nfs/super.c (see commit 56463e50 "NFS: Use super.c for NFSROOT mount option parsing"). That commit changed the default NFSROOT mount options to be the same as those employed by user space mounts. As it turns out, these new default mount options are not tolerated by many embedded systems. So far these problems have been due to specific behavior of certain embedded NICs. The NFS community does not have such hardware on hand for running tests. Commit 53d47375 recently introduced a clean way to specify default mount options for NFSROOT, so we can now easily restore the traditional defaults for NFSROOT: vers=2,udp,rsize=4096,wsize=4096 This should revert the new default NFSROOT mount options introduced with commit 56463e50.
