* NFS4: on a O_EXCL OPEN make sure SETATTR sets the fields holding the verifierJeff Layton2007-07-102-2/+27
| | | | | | | | | | | | | | | | | The Linux NFS4 client simply skips over the bitmask in an O_EXCL open call and so it doesn't bother to reset any fields that may be holding the verifier. This patch has us save the first two words of the bitmask (which is all the current client has #defines for). The client then later checks this bitmask and turns on the appropriate flags in the sattr->ia_verify field for the following SETATTR call. This patch only currently checks to see if the server used the atime and mtime slots for the verifier (which is what the Linux server uses for this). I'm not sure of what other fields the server could reasonably use, but adding checks for others should be trivial.

* NFSv4: Ensure that nfs4_do_close() doesn't race with umountTrond Myklebust2007-07-104-38/+26
| | | | | | | | | | | nfs4_do_close() does not currently have any way to ensure that the user won't attempt to unmount the partition while the asynchronous RPC call is completing. This again may cause Oopses in nfs_update_inode(). Add a vfsmount argument to nfs4_close_state to ensure that the partition remains mounted while we're closing the file.

* Make common helpers for seq_files that work with list_headsPavel Emelianov2007-07-101-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many places in kernel use seq_file API to iterate over a regular list_head. The code for such iteration is identical in all the places, so it's worth introducing a common helpers. This makes code about 300 lines smaller: The first version of this patch made the helper functions static inline in the seq_file.h header. This patch moves them to the fs/seq_file.c as Andrew proposed. The vmlinux .text section sizes are as follows: 2.6.22-rc1-mm1: 0x001794d5 with the previous version: 0x00179505 with this patch: 0x00179135 The config file used was make allnoconfig with the "y" inclusion of all the possible options to make the files modified by the patch compile plus drivers I have on the test node. This patch: Many places in kernel use seq_file API to iterate over a regular list_head. The code for such iteration is identical in all the places, so it's worth introducing a common helpers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts part of an earlier patch which tried to reclaim gfs2_bufdata structures too early and resulted in a "use after free" case (this bit from me).

| * | [GFS2] Remove i_mode passing from NFS File HandleWendy Cheng2007-07-094-41/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GFS2 has been passing i_mode within NFS File Handle. Other than the wrong assumption that there is always room for this extra 16 bit value, the current gfs2_get_dentry doesn't really need the i_mode to work correctly. Note that GFS2 NFS code does go thru the same lookup code path as direct file access route (where the mode is obtained from name lookup) but gfs2_get_dentry() is coded for different purpose. It is not used during lookup time. It is part of the file access procedure call. When the call is invoked, if on-disk inode is not in-memory, it has to be read-in. This makes i_mode passing a useless overhead. Signed-off-by: S. Wendy Cheng <wcheng@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GFS2 lookup code doesn't ask for inode shared glock. This implies during in-memory inode creation for existing file, GFS2 will not disk-read in the inode contents. This leaves no_formal_ino un-initialized during lookup time. The un-initialized no_formal_ino is subsequently encoded into file handle. Clients will get ESTALE error whenever it tries to access these files. Signed-off-by: S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This should have been part of the NFS patch #1 but somehow I missed it when packaging the patches. It is not a critical issue as the others (I hope). RHEL 5.1 31.el5 kernel runs fine without this change. Our truncate code is chopped into two parts, one for vfs inode changes (in vmtruncate()) and one of gfs inode (in gfs2_truncatei()). These two operatons are, unfortunately, not atomic. So it could happens that vmtruncate() succeeds (inode->i_size is changed) but gfs2_truncatei fails (say kernel temporarily out of memory). This would leave gfs inode i_di.di_size out of sync with vfs inode i_size. It will later confuse gfs2_commit_write() if a write is issued. Last time I checked, it will cause file corruption.
