 2009/03/??	*** Release of OpenSSI 1.9.6 ***
 
+2009/02/23	rogertsang <[email protected]>
+	* CFS:
+	- Fix cfsd_create() possible dentry leak or operating on dereferenced dentry.
+	- 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.
+	- Move redundant struct svrcfstok initialization to kmem cache constructor. (#ifdef SVRCFS_TOKEN_KMEM_CACHE)
+	- Regression:
+	  - Possible busy inodes after unmounting. (#ifdef RCU_CFSTOK_TABLE)
+	  - 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)
+
+	* ICS:
+	- Fix uninitialized linked list pointers in client and server handle structures.
+
+	* IPC:
+	- Fix uninitialized list_head in rmtunix_socket_info structure; SSI-1.9.0 bug. (#ifdef IPC_STALE_RMTUNIX_CACHE_FIX)
+	- 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.
+	  - 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.
+	- Fix shm_ids_svr table race; mutex not held or wrong mutex held. (#ifdef IPC_SHM_RACE_FIX)
+	- Downgrade NSC_IPC_WRLOCK() where appropriate; reduce contention. (#ifdef NSC_IPC_RWLOCK_DOWNGRADE)
+
+	* 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.
+	- Regression:
+	  - real_lookup() possibly returning unreferenced dentry instead of -ENOENT. (#ifndef REAL_LOOKUP_SSI_1_9_3_FIXED_PLS_VERIFY)
+
+	* VPROC:
+	- Remove deprecated RW semaphore implementation of vproc list lock.
+	- VPROC_LOCATE_PID() further avoid global list lock; no longer support LVP_NOLOCK flag. (#ifdef VPROC_RCU_LIST)
+	- 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)
+	- Move redundant struct vproc initialization to kmem cache constructor. (#ifdef VPROC_KMEM_CACHE)
+	- Regression:
+	  - semi-deadlock in vproc_slave_carelist_create(); might sleep
+	    while holding vproc list lock. (#ifdef VPROC_LIST_SPINLOCK)
+	  - VPROC_LOCATE_PID() race could corrupt vproc hash table. (#ifdef VPROC_RCU_LIST)
+	  - Process migration traversing rmtfb path while importing SHM fd's; caused by fb_svrnode macro. (#ifdef REOP_EXPORT_PATH_SVRNODE)
+
 2009/02/07	rogertsang <[email protected]>
 	* IPC:
 	- Fix missing sock_hold() for sock reference in rmtunix_socket_info structure. (#ifdef IPC_STALE_RMTUNIX_CACHE_FIX)
