Noticed by Tom Talpey <tmt@netapp.com>: OBTW, there's a nit on that memcpy, too. The r_addr is an array, so memcpy(&map->r_addr is passing the address of the array as a char **. It's the same as map->r_addr, but technically the wrong type. Signed-off-by:

Fix some problems with rpcbind v3 and v4 queries from the in-kernel rpcbind client: 1. The r_addr argument must be a full universal address, not just an IP address, and 2. The universal address in r_addr is the address of the remote rpcbind server, not the RPC service being requested This addresses bugzilla.kernel.org report 8891 for 2.6.23-rc and greater. In addition, if the rpcbind client is unable to start the rpcbind request, make sure not to leak the xprt. Signed-off-by: -

Prepare for adding IPv6 support to the RPC client by adding IPv6 capabilities to rpcbind. Note that this is support on the query side only; registering IPv6 addresses with the local portmapper will come later. Note we have to take care not to fall back to using version 2 of the rpcbind protocol if we're dealing with IPv6 address. Version 2 doesn't support IPv6 at all. Signed-off-by:

Add support for the NFS client's need to export volume information with IP addresses formatted in hex instead of decimal. This isn't used yet, but subsequent patches (not in this series) will change the NFS client to use this functionality. Signed-off-by:

A minor thing, but useful when working with a server with multiple addrs. This looks like it might also be necessary if Miklos' effort to eliminate /etc/mtab ever comes to fruition. When displaying mount options in /proc/mounts, the kernel prints "addr=hostname". This info is redundant since we already have the hostname displayed as part of the "device" section of the mount. This patch changes it to display the IP address to which the socket is connected. Signed-off-by:

I would like to discuss the idea that the current checks for attribute timeout using time_after are inadequate for 32bit architectures, since time_after works correctly only when the two timestamps being compared are within 2^31 jiffies of each other. The signed overflow caused by comparing values more than 2^31 jiffies apart will flip the result, causing incorrect assumptions of validity. 2^31 jiffies is a fairly large period of time (~25 days) when compared to the lifetime of most kernel data structures, but for long lived NFS mounts that can sit idle for months (think that for some reason autofs cannot be used), it is easy to compare inode attribute timestamps with very disparate or even bogus values (as in when jiffies have wrapped many times, where the comparison doesn't even make sense). Currently the code tests for attribute timeout by simply adding the desired amount of jiffies to the stored timestamp and comparing that with the current timestamp of obtained attribute data with time_after. This is incorrect, as it returns true for the desired timeout period and another full 2^31 range of jiffies. In testing with artificial jumps (several small jumps, not one big crank) of the jiffies I was able to reproduce a problem found in a server with very long lived NFS mounts, where attributes would not be refreshed even after touching files and directories in the server: Initial uptime: 03:42:01 up 6 min, 0 users, load average: 0.01, 0.12, 0.07 NFS volume is mounted and time is advanced: 03:38:09 up 25 days, 2 min, 0 users, load average: 1.22, 1.05, 1.08 # ls -l /local/A/foo/bar /nfs/A/foo/bar -rw-r--r-- 1 root root 0 Dec 17 03:38 /local/A/foo/bar -rw-r--r-- 1 root root 0 Nov 22 00:36 /nfs/A/foo/bar # touch /local/A/foo/bar # ls -l /local/A/foo/bar /nfs/A/foo/bar -rw-r--r-- 1 root root 0 Dec 17 03:47 /local/A/foo/bar -rw-r--r-- 1 root root 0 Nov 22 00:36 /nfs/A/foo/bar We can see the local mtime is updated, but the NFS mount still shows the old value. The patch below makes it work: Initial setup... 07:11:02 up 25 days, 1 min, 0 users, load average: 0.15, 0.03, 0.04 # ls -l /local/A/foo/bar /nfs/A/foo/bar -rw-r--r-- 1 root root 0 Jan 11 07:11 /local/A/foo/bar -rw-r--r-- 1 root root 0 Jan 11 07:11 /nfs/A/foo/bar # touch /local/A/foo/bar # ls -l /local/A/foo/bar /nfs/A/foo/bar -rw-r--r-- 1 root root 0 Jan 11 07:14 /local/A/foo/bar -rw-r--r-- 1 root root 0 Jan 11 07:14 /nfs/A/foo/bar Signed-off-by:

Hi. Attached is a patch to modify the NFS client code to support 64 bit ino's, as appropriate for the system and the NFS protocol version. The code basically just expand the NFS interfaces for routines which handle ino's from using ino_t to u64 and then uses the fileid in the nfs_inode instead of i_ino in the inode. The code paths that were updated are in the getattr method and the readdir methods. This should be no real change on 64 bit platforms. Since the ino_t is an unsigned long, it would already be 64 bits wide. Thanx... ps Signed-off-by:Peter Staubach <staubach@redhat.com> Signed-off-by:

This will allow rpc.gssd to use inotify instead of dnotify in order to locate new rpc upcall pipes. This also requires the exporting of __audit_inode_child(), which is used by fsnotify_create() and fsnotify_mkdir(). Ccing David Woodhouse. Cc: David Woodhouse <dwmw2@infradead.org> Signed-off-by: -

The recent mv_fill_sg() rewrite, to fix a data corruption problem related to IOMMU virtual merging, forgot to account for the potentially-increased size of the scatter/gather table after its run. Additionally, the DMA boundary is reduced from 0xffffffff to 0xffff to more closely match the needs of mv_fill_sg(). Signed-off-by:
