Patch 86222-25 for Software Release 2.2.2
C613-10319-00 REV X

Sometimes during compaction when the file system was erasing blocks 
belonging to deleted files, one of the files was transferred rather than 
deleted. However, its directory entry was deleted, so the file was not 
visible with a SHOW FILE command but was visible with a SHOW 
FFILE command.

During compaction if the amount of free space was less than two erase 
blocks (including the "spare" erase block), the file system erroneously 
reported that a large amount of space was available for a new file due 
to an underflow problem. When a new file was written it would corrupt 
existing data.

If the file system was completely full and the deletion of a single file led 
to a compaction, the file system reported that it was continually 
compacting. This was because it was repeatedly searching through a 
linked list of file headers.

A byte of data from FLASH was incorrectly returning the value 0xFF.

When a file was renamed using upper case letters, the renamed file did 
not appear in the file directory but did appear in FLASH. Also, if a 
SHOW FFILE CHECK command was executed after renaming the file, 
the file system would appear to hang. All file names must now be lower 
case.

Multiple TTY sessions could edit the same file. This caused 
unpredictable behaviour when the TTY sessions closed the files.

A new command, SHOW FFILE VERIFY, has been added. This command 
steps through the file system headers starting with file zero and finishing at 
the end of the last reachable file. It then verifies that all FLASH locations 
from the end of the last reachable file to the beginning of file zero are in an 
erased state. Errors are reported as they are found.

The source IP address in DVMRP 

prune

 and 

graft

 messages was incorrect. 

This issue has been resolved.

Firewall subnet NAT rules were not working correctly from the private to 
the public side of the firewall. Traffic from the public to private side 
(destined for subnet NAT) was discarded. These issues have been resolved. 
ICMP traffic no longer causes a RADIUS lookup for access authentication, 
but is now checked by ICMP handlers for attacks and eligibility. If the ICMP 
traffic matches a NAT rule, NAT will occur on inbound and outbound 
traffic. HTTP 1.0 requests sometimes caused the firewall HTTP proxy to 
close prematurely. Cached TCP sessions were sometimes not hit correctly. 
These issues have been resolved.

When an IP Multihomed interface was used as an OSPF interface, 
neighbour relationships were only established if the IP interface for OSPF 
was added first in the configuration. Now, OSPF establishes neighbour 
relationships regardless of the IP Multihomed interface configuration order.

The SHOW VRRP command now shows the number of trigger activations 
for the Upmaster and Downmaster triggers.
