* [PATCH] lockdep: annotate sunrpc codeArjan van de Ven2006-07-03
| | | | | | | | | | | | | | | | | | | | | Add i_mutex ordering annotations to the sunrpc rpc_pipe code. This code has 3 levels of i_mutex hierarchy in some cases: parent dir, client dir and file inside client dir; the i_mutex ordering is I_MUTEX_PARENT -> I_MUTEX_CHILD -> I_MUTEX_NORMAL This patch applies this ordering annotation to the various functions. This is in line with the VFS expected ordering where it is always OK to lock a child after locking a parent; the sunrpc code is very diligent in doing this correctly. Has no effect on non-lockdep kernels.

| * [PATCH] VFS: Permit filesystem to override root dentry on mountDavid Howells2006-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend the get_sb() filesystem operation to take an extra argument that permits the VFS to pass in the target vfsmount that defines the mountpoint. The filesystem is then required to manually set the superblock and root dentry pointers. For most filesystems, this should be done with simple_set_mnt() which will set the superblock pointer and then set the root dentry to the superblock's s_root (as per the old default behaviour). The get_sb() op now returns an integer as there's now no need to return the superblock pointer. This patch permits a superblock to be implicitly shared amongst several mount points, such as can be done with NFS to avoid potential inode aliasing. In such a case, simple_set_mnt() would not be called, and instead the mnt_root and mnt_sb would be set directly. The patch also makes the following changes: (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount pointer argument and return an integer, so most filesystems have to change very little. (*) If one of the convenience function is not used, then get_sb() should normally call simple_set_mnt() to instantiate the vfsmount. This will always return 0, and so can be tail-called from get_sb(). (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the dcache upon superblock destruction rather than shrink_dcache_anon(). This is required because the superblock may now have multiple trees that aren't actually bound to s_root, but that still need to be cleaned up. The currently called functions assume that the whole tree is rooted at s_root, and that anonymous dentries are not the roots of trees which results in dentries being left unculled. However, with the way NFS superblock sharing are currently set to be implemented, these assumptions are violated: the root of the filesystem is simply a dummy dentry and inode (the real inode for '/' may well be inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries with child trees. [*] Anonymous until discovered from another tree. (*) The documentation has been adjusted, including the additional bit of changing ext2_* into foo_* in the documentation.

* | SUNRPC: NFS_ROOT always uses the same XIDsChuck Lever2006-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The XID generator uses get_random_bytes to generate an initial XID. NFS_ROOT starts up before the random driver, though, so get_random_bytes doesn't set a random XID for NFS_ROOT. This causes NFS_ROOT mount points to reuse XIDs every time the client is booted. If the client boots often enough, the server will start serving old replies out of its DRC. Use net_random() instead. Test plan: I/O intensive workloads should perform well and generate no errors. Traces taken during client reboots should show that NFS_ROOT mounts use unique XIDs after every reboot.

* | SUNRPC: select privileged port numbers at randomChuck Lever2006-06-09
|/ | | | | | | | | | | | | | | | | | | Make the RPC client select privileged ephemeral source ports at random. This improves DRC behavior on the server by using the same port when reconnecting for the same mount point, but using a different port for fresh mounts. The Linux TCP implementation already does this for nonprivileged ports. Note that TCP sockets in TIME_WAIT will prevent quick reuse of a random ephemeral port number by leaving the port INUSE until the connection transitions out of TIME_WAIT. Test plan: Connectathon against every known server implementation using multiple mount points. Locking especially.

* RPCSEC_GSS: fix leak in krb5 code caused by superfluous kmallocJ. Bruce Fields2006-04-19

We were using a transition to CACHE_VALID to see if that was needed, however that is wrong as an expired entry will still be marked 'valid' (as the data is valid and will need to be released). So instead use an off transition for CACHE_PENDING which is exactly the right thing to test. - Add a little bit more debugging info.

Note that per_cpu shenanigans are not required here because the RPC client already serializes on the transport write lock. Test plan: Compile kernel with CONFIG_NFS enabled. Basic performance regression testing with high-speed networking and high performance server. Signed-off-by: Chuck Lever <cel@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

Separate timers for RPC round trip and RPC execution time show how long RPC requests wait in queue before being sent. Eventually these will be accumulated at xprt_release time in one place where they can be viewed from userland. Test plan: Compile kernel with CONFIG_NFS enabled.
