Update of /cvsroot/ssic-linux/openssi/kernel/cluster/ssi/net
In directory fdv4jf1.ch3.sourceforge.com:/tmp/cvs-serv23689/cluster/ssi/net

Modified Files:
      Tag: OPENSSI-FC
	ipvs_svr.c 
Log Message:
CFS:
- Fix possible server token table hash key race with PFS file handle data.
- Further avoid ssi_get_super() to reduce contention. We don't cross mount points.
- Switch to Linux get_empty_filp() to get unused file structure for svrcfstok structure.
- Regression:
  - Possible inode leak when out of memory doing export ops get_dentry. (#ifdef CFS_EXPORT_OPS)
  - Possibly missed drop_super() while performing export ops get_dentry. (#ifdef CFS_FH_TO_DENTRY_ANON)

IPC:
- Fix uninitialized spin lock in kern_ipc_perm structure (in SSI context).
- Fix uninitialized linked list pointers in unixnm_svr_entry and unixnm_cache_entry structures.
- SHM dentry lookup bug fixes:
  - Error -ENOENT in CFS (negative dentry) due to not validating against PFS.
  - Fix SHM negative dentry lookup could cause future memory corruption.
    - Did not increment inode count when instantiating dentry.
    - Bad dentry reference count side-effect due to incorrect return value for Linux namespace architecture.

IPVS:
- Fix uninitialized linked list pointers in ipvs_dirinfo and portweight_list structures.

SSI:
- Fix dentry race calling __d_path() outside dcache lock. (#ifdef SSI_DCACHE_RACE_FIX)
- Fix uninitialized linked list pointers in structures rmtfb_cmn, ssidev_hash, fifonm_svr_entry, fifonm_cache_entry, and ssipty_svr_
entry.

VPROC:
- Fix possibly missed drop_super() during process migration exporting of file descriptors.
- Fix partially initialized proc_root_readdir_cookie structure.
- semundo_load_msg() handle process sysvsem.undo_list->proc_list race take two. (#ifdef VPROC_UNLOAD_SETSCHED_SMP)
- Regression:
  - Process migration traversing rmtfb path while importing SHM fd's; caused by fb_svrnode macro. (#ifdef REOP_EXPORT_PATH_SVRNODE)
