2 Patch Release Note

Features in 86222-22

PCR 02136 Module: FIREWALL Network affecting: No
The firewall was blocking outbound ICMP packets when the associated private interface had a ‘deny all’ rule. The passing of ICMP packets should be controlled by the ICMP_FORWARDING and PING parameters. This issue has been resolved.
PCR 02184 Module: FFS FILE TTY Network affecting: No
This patch supersedes PCRs 02073, 02081, 02086 and 02105. In addition to enhancements in the preceding PCRs, this PCR now also resolves the following issues:
If a compaction was started within 60ms of a file write commencing, the file being written was placed in the wrong location in the file system. This led to file corruption during subsequent compactions.
If a file load occurred during compaction, an incomplete copy of the file was loaded. The load also put the file into the wrong part of the file system once the compaction had moved beyond the part of the file that had been loaded.
A fatal error occurred during compaction if a file was marked as deleted when it was being transferred.
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.

C613-10319-00 REV U
Patch 86222-22 For Rapier Switches and AR800 Series Modular Switching Routers 3
PCR 02192 Module: IP Network affecting: No
The source IP address in DVMRP prune and graft messages was incorrect. This issue has been resolved.
PCR: 02241 Module: FIREWALL Network affecting: No
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.
PCR: 02359 Module: IPG Network affecting: No
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.
PCR: 02395 Module: VRRP, TRG Network affecting: No
The SHOW VRRP command now shows the number of trigger activations for the Upmaster and Downmaster triggers.
PCR: 02396 Module: DHCP Network affecting: No
DHCP RENEW request messages are now unicast (as defined in the RFC), not broadcast.
PCR 02400 Module: CORE, FFS, FILE,
Network affecting: No
INSTALL, SCR
If a problem occurred with NVS, some cri tical files were lost. As a result, the equipment was forced to load only boot ROM software at boot time. This patch combined with the new version of the boot ROM software (pr1-1.2.0 for the AR700 series) resolves this issue.
PCR 02408 Module: SWI Network affecting: No
The EPORT parameter in the SHOW SWITCH L3FILTER ENTRY command was displaying incorrectly after an issue was resolved in PCR02374. The command now displays correctly.
PCR: 02427 Module: DHCP Network affecting: No
Patch 86222-22 for Software Release 2.2.2 C613-10319-00 REV U
DHCP entry reclaim checks are now delayed by 10 seconds if the entry is unroutable because the interface is not up.
PCR: 02463 Module: DVMRP, IPG Network affecting: No
Support for multi-homed interfaces has been added.
PCR 02465 Module: TTY Network affecting: No
Under some circumstances a fatal error occurred if a large amount of data was pasted onto the command line. This issue has been resolved.
4 Patch Release Note
PCR: 02489 Module: SWI Network affecting: No
When the switch was under heavy learning load, some MAC address were lost. This issue has been resolved.
PCR 02506 Module: OSPF, IPG Network affecting: No
In the ADD IP ROUTE FILTER command, when the optional parameter INTERFACE was included, the filter was not applied to the flooding of OSPF external LSAs. Also, in the command SHOW IP ROUTE FILTER, the output of the interface name was truncated when the name was more than six characters long. These issues have been resolved.
PCR: 02509 Module: DVMRP Network affecting: No
The source net mask has been removed from DVMRP prune, graft and graft-ack messages.
PCR 02526 Module: DVMRP Network affecting: No
Under some circumstances, multiple default routes were created for DVMRP. This issue has been resolved.
PCR 02538 Module: DVMRP Network affecting: No
The source mask is now always 0xffffffff in the DVMRP forwarding table.
The temporary route in the DVMRP route table was not displaying correctly. This issue has been resolved.
An IGMP entry was erroneously added for the reserved IP address. This issue has been resolved.

Patch 86222-21 includes all issues resolved and enhancements released in previous patches for Software Release 2.2.2, and the following enhancements:
PCR: 02167 Module: FIREWALL Network affecting: No
Locally generated ICMP messages, that were passed out through a firewall interface because they were associated with another packet flow, had their source address changed to that of the associated packet flow and were also forwarded with incorrect IP checksums. This only occurred when there was no NAT associated with the packet flow. This issue has been resolved.

C613-10319-00 REV U
Patch 86222-22 For Rapier Switches and AR800 Series Modular Switching Routers 5
PCR: 02236 Module: FIREWALL Network affecting: No
Sometimes the retransmission of an FTP packet was not permitted through the Firewall. This issue has been resolved.
PCR: 02245 Module: VRRP Network affecting: No
VRRP returned an incorrect MAC address for an ARP request. This issue has been resolved.
PCR: 02327 Module: IPG/FIREWALL Network affecting: No
In some situations, multihomed interfaces caused the Firewall to apply NAT and rules incorrectly when packets were received from a subnet that was not attached to the receiving interface. This issue has been resolved.
PCR: 02329 Module: DHCP Network affecting: No
An ARP entry for a host has been removed whenever a DHCP DISCOVER or DHCP REQUEST message is received from the host. This allows for clients changing ports on a switch.
PCR: 02332 Module: IPSEC Network affecting: No
The sequence number extracted from the AH and ESP header was in the wrong endian mode, which caused an FTP error with IPSEC anti-replay. This issue has been resolved.
PCR: 02343 Module: PPP Network affecting: No
When acting as a PPPoE Access Concentrator (AC), if a PPPoE client sent discovery packets without the "host-unique" tag, the discovery packets sent by the AC were corrupted. This issue has been resolved.
PCR: 02368 Module: IPG/IGMP Network affecting: No
IGMP failed to create an automatic IGMP membership with no joining port when it received multicast data that no ports were interested in, when IP TimeToLive was set to 1 second. Also, IGMP erroneously sent a query on an IGMP enabled IP interface even when IGMP was disabled. These issues have been resolved.
PCR: 02374 Module: SWI Network affecting: No
In the ADD SWITCH L3FILTER command, the EPORT parameter incorrectly accepted the value 62-63 as multicast and broadcast ports 63-64. This issue has been resolved.
PCR: 02397 Module: DVMRP Network affecting: No
Patch 86222-22 for Software Release 2.2.2 C613-10319-00 REV U
After a prune lifetime had expired, the interface was not joined back to the DVMRP multicast delivery tree. This issue has been resolved.
PCR: 02404 Module: IPG Network affecting: No
DVMRP multicast forwarding failed to send tagged packets to a tagged port. Packets were erroneously sent untagged to tagged ports. This issue has been resolved.

Patch 86222-20 includes all issues resolved and enhancements released in previous patches for Software Release 2.2.2, and the following enhancements:
PCR: 01226 Module: IGMP Network affecting: Yes
The IGMP specific query sent by the router/switch now contains the correct default response time of 1 second. Also, ifOutOctets in the VLAN interface MIB now increments correctly.
PCR: 01270 Module: APPLE Network affecting: No
If a port did not belong to an ethernet interface, or was not directly connected to the seed port it could not receive advertised router numbers. This issue has been resolved.
PCR: 01285 Module: OSPF Network affecting: No
When an interface went down (or was disabled) on an AS border router, the external routes were not removed from the routing domain. Such routes are now removed by premature aging.
PCR: 02024 Module: IPG Network affecting: No
Proxy Arp can now be used on VLAN interfaces.
PCR: 02122 Module: FIREWALL Network affecting: No
A fatal error sometimes occurred if a TCP session originating on the public side of the firewall sent packets before the session was established with the host on the private side of the firewall. This issue has been resolved.
PCR: 02128 Module: FIREWALL Network affecting: No
Some FTP packets handled by the firewall were forwarded with incorrect sequence numbers, causing FTP sessions to fail. This issue has been resolved.
PCR: 02150 Module: CORE, SNMP Network affecting: No
When passing 64-bit counters in an SNMP packet, only the lower 32 bits were passed. Now the full 64 bits of the counter will be returned if all are required.
PCR: 02158 Module: FIREWALL Network affecting: No
When a TCP RST/ACK was received by a firewall interface, the packet that was passed to the other side of the firewall lost the ACK flag, and had an incorrect ACK number. This issue has been resolved.

Patch 86222-22 For Rapier Switches and AR800 Series Modular Switching Routers 7
PCR 02161 Module: IPG Network affecting: No
The IP Filter SIZE parameter was not being applied correctly. This issue has been resolved.
PCR 02162 Module: IPG Network affecting: No
The SET IP FILTER command would not update the SIZE parameter correctly. This issue has been resolved.
PCR 02172 Module: IPG Network affecting: No
The TOS field in IP packets was not being processed by IP POLICY filters with an identifier greater than 7. This issue has been resolved.
PCR: 02174 Module: FIREWALL Network affecting: No
A feature has been added that makes pings pass from the source IP address of the public interface to the IP address on the private interface in the firewall.
PCR: 02195 Module: SWI Network affecting: No
If a port on a Rapier 48 or Rapier 48 i went down, some associated entries were not promptly removed from the forwarding, Layer 3 and default IP tables. This issue has been resolved.
PCR: 02198 Module: DHCP Network affecting: Yes
This PCR includes the following enhancements:
A new command, SET DHCP EXTENDID allows for multiple DHCP clients, and handling of arbitrary client IDs on the server.
Static DHCP entries now return to the correct state when timing out.
DHCP entry hashes now have memory protection to prevent fatal errors.
DHCP client now retransmits XID correctly.
Lost OFFER messages on the server are now handled correctly.
The DHCP server now correctly handles DHCP clients being moved to a different interface on the DHCP server after they’ve been allocated an IP address.
PCR: 02203 Module: IPG Network affecting: No
Responses to DNS requests received by a DNS relay agent, and forwarded to the DNS server, were returned to the requester with a source IP address of the DNS server rather than the DNS relay agent. This issue has been resolved.
Patch 86222-22 for Software Release 2.2.2 C613-10319-00 REV U
PCR: 02208 Module: LOG Network affecting: No
Log messages are no longer stored in NVS.
PCR: 02214 Module: IPG Network affecting: No
A buffer leak occurred when a large number of flows (over 4000) were in use and needed to be recycled. This issue has been resolved.
8 Patch Release Note
PCR: 02215 Module: FILE Network affecting: No
When the only feature licence in the feature licence file was disabled, the licence file stored on FLASH memory did not change. This was due to a previous enhancement in PCR 02184 which prevented existing files being deleted before a new version was stored. This issue has been resolved.
PCR: 02220 Module: SWI Network affecting: No
The EPORT parameter in the ADD SWITCH L3FILTER ENTRY and SET SWITCH L3FILTER ENTRY commands was matching multicast and broadcast packets with software filtering. This issue has been resolved.
PCR: 02224 Module: SWI Network affecting: No
Some switch chip register values have been changed to improve QoS support on Rapier G6 and Rapier G6f switches.
PCR: 02229 Module: IPG Network affecting: No
The PURGE IP command now resets the IP route cache counters to zero.
PCR: 02242 Module: IPG Network affecting: No
On a Rapier 24, adding an IP interface over a FR interface caused an ASSERT debug fatal error. This issue has been resolved.
PCR: 02246 Module: VRRP Network affecting: No
The ARL entry for the virtual router MAC was incorrectly showing a numerical value. The entry now shows the CPU’s port value.
PCR: 02250 Module: FIREWALL Network affecting: No
Sometimes the Firewall erroneously used NAT. This issue has been resolved.
PCR: 02259 Module: DHCP, IPG Network affecting: No
A dual Ethernet router was incorrectly accepting an IP address from a DHCP server when the offered address was on the same network as the other Ethernet interface. An error is now recorded when DHCP offers an address that is in the same subnet as another interface.
PCR: 02260 Module: TTY Network affecting: No
When a ‘\n’(LF) character was received, the router/switch did not recognise this as the termination of a command over Telnet. This issue has been resolved.
PCR: 02262 Module: DNS Network affecting: No
Responses to MX record requests were not handled correctly if the preferred name in the MX record differed from the one that was requested. This issue has been resolved.
Patch 86222-22 for Software Release 2.2.2
C613-10319-00 REV U
Patch 86222-22 For Rapier Switches and AR800 Series Modular Switching Routers 9
PCR: 02263 Module: VRRP Network affecting: No
The virtual MAC address was used as the source MAC for all packets forwarded on an interface associated with a Virtual Router (VR). This was confusing when multiple VRs were defined over the same interface because only one virtual MAC address was ever used. The other virtual MAC addresses (for the other VR's) were only used if the source IP address matched the VR’s IP address. To avoid this confusion, the system MAC address is now always used unless the source IP address of the packet is the same as the VR’s IP address.
PCR: 02264 Module: PIM, DVMRP, SWI Network affecting: No
PIM or DVMRP failed to see any data if IGMP snooping was on and DVMRP or PIM was enabled after the data stream had reached the router/ switch. This issue has been resolved.
PCR: 02265 Module: FIREWALL Network affecting: No
MAC address lists were not working with Firewall rules. This issue has been resolved.
PCR: 02268 Module: FIREWALL Network affecting: No
HTTP requests from a fixed IP address were erroneously reported as a host scan attack in the Firewall deny queue. This issue has been resolved.
PCR: 02269 Module: DUART, TM Network affecting: No
Under certain circumstances, the Asyn Loopback Test failed. This issue has been resolved.
PCR: 02274 Module: TPAD Network affecting: No
ARL message interrupts have been re-enabled after a software table rebuild to fix synchronisation of the software forwarding database with the hardware table.
PCR: 02275 Module: OSPF Network affecting: No
Some routes were not added into the OSPF route list, and therefore were not added into the IP route table. This issue has been resolved.
PCR: 02276 Module: FIREWALL Network affecting: No
The CREATE CONFIG command did not save the SOURCEPORT parameter to the configuration file when the low value of the source port range was set to zero. This issue has been resolved.
PCR: 02287 Module: IPG Network affecting: No
Patch 86222-22 for Software Release 2.2.2 C613-10319-00 REV U
Existing IGMP groups were not deleted when IGMP was disabled globally or on the associated interface. This gave the groups very high timeout values. This issue has been resolved.
PCR: 02299 Module: VRRP Network affecting: No
If a packet with a destination IP address equal to a VRRP IP address was received when the router didn’t own the IP address, (because it didn’t have an interface with that IP address) the router incorrectly tried to forward the packet and send an ICMP “redirect” message to the source. Now, if such a packet is received, it will be discarded and an ICMP “host unreachable” message will be sent to the source.
