Here's
* the README from a patch tape dated 6/8 (from Massachusetts CSC)
* a list of diffs from the 4/26 patch tape
* the checksums from the 6/15 tape

README
Run the install_patch script to install these patches. The script
checks the sccs id module and updates the binaries for anyone found
out of rev. You MUST be root to run this script.
uipc_msg.o msg.h
----------------
panic: bad rmfree
Can occur when processes using message queues swap.
File system problems
--------------------
gfs/{gfs_bio.o gfs_gnodeops.o gfs_syscalls.o}
nfs/{nfs_server.o nfs_vnodeops.o vnodeops_gfs.o nfs_subr.o nfs_gfsops.o}
ufs/{ufs_gnodeops.o ufs_gnode.o ufs_syscalls.o}
sys/{kern_sig.o kern_acct.o}
These files do not map one-to-one with bugs.
The bugs that these files fix are:
1. Change to file generation number increments on NFS server.
Would cause "NFS server: stale fhandle" message on server
(should have only caused problems when accessing through
multiple links to same file via NFS, and one link removed).
2. Fix for mode of named pipe created over NFS.
3. Fix for NFS client gnode race condition.
Can cause gfs_unlock: unlocked gnode panic.
4. Better tempname algorithm when unlinking open files
over NFS. Extremely unlikely to be seen; results in
stale fhandle error.
5. Various fs panics when accounting changes state.
(km_free: bad dealloc when shutting system down)
6. bhalt() changes. It could conceivably be writing out
read-ahead blocks to disk at shutdown and panics now.
7. Access is not allowed over NFS for a filesystem that
has not been explicitly exported. (Not true without
these patches). However, changing the exports file while
a system is running is not enough to prohibit access
from a filesystem that is currently exported.
The filesystem must also be unmounted and remounted on
the server (tough for root). After that, any attempt to
access that filesystem via NFS will be refused with
ESTALE and an "unexported" message is printed on the server.
8. A df on a remote NFS filesystem now has the same effect
as doing a df on the server - not true before, a df
on the server was necessary for the stats, as seen by
client, to be updated.
9. The utimes() system call now has the proper semantics
over NFS - the owner of a file can change the times even
if he does not have write permission.
10. Better NFS server fhandle error messages.
tmscp.o tmscp.h tmscpreg.h
--------------------------
Fixes all kinds of panics, panic: bad rmfree in the tmscp driver
panic: bad rmfree in other drivers when freeing uba maps. The old
driver could allow the writing of K mem in improper areas.
uerf.bin
--------
The file uerf.bin contains erroneuos data. UERF uses this file to
do bit-to-text translations. Error log reports can contain bad data.
Some of the bad information is obvious, such as VERY large or negative
numbers for MSCP disk cylinder or head addresses.
fsck
----
This replaces the fsck command that was distributed with ULTRIX-32
V2.2. It fixes panic: free: freeing free block.
kern_synch.o
------------
Processes were running slowly because the process priority never
decayed if the process had taken a signal.
gfs_descrip.o
-------------
Systems crashed periodically during execution of closef() routine with
segmentation fault.
dlogind
-------
Fixes wtmp corruption problem. Two processes could open the wtmp file
for writing at the same time. This would cause corruption of wtmp.
* This is only if you have DECnet installed.
lat_scl1.o lat_slot.o lat_vc.o
------------------------------
System would panic with segmentation fault when picking up an empty
slot. Also, users would be dropped from LAT.
s5make
------
Fixed to handle archives properly.
ss.o
----
Fixes problem with MicroVAX 2000 console port and port 2. If a modem
was attached to port 2 and you logged off the console, port 2 would be
disconnected. (See V2.2 Release Notes, p. 2-15 for more information.)
dmb.o
-----
Fixes line hangs ...
uucico
------
Fixes problem with uucico hanging.
