RHBA-2009:1372 - Bug Fix Advisory

Topic

Updated net-snmp packages that fix various bugs and add enhancements are
now available.

Description

The Simple Network Management Protocol (SNMP) is a protocol used for
network management. The net-snmp packages include various SNMP tools: an
extensible agent; an SNMP library; tools for requesting or setting
information from SNMP agents; tools for generating and handling SNMP traps;
a version of the netstat command which uses SNMP; and a Tk/Perl MIB browser.

These updated net-snmp packages provide fixes for the following bugs:

• using "snmpwalk" to walk a host with automounted NFS mounts sometimes

resulted in the snmpd server timing out if the NFS mount became
unresponsive. This update provides a new directive for the snmpd.conf
configuration file, "skipNFSInHostResources", which allows snmpwalk to skip
over automounted NFS mounts when performing a walk. (BZ#461631)

• the snmp daemon did not correctly report the speeds of network interfaces

when they were greater than 4 Gbit/s. With this update, the actual speed of
10-Gigabit Ethernet (10GbE) network cards are accurately reported. (BZ#464061)

• the snmpd daemon no longer prints spurious "error on subcontainer ''

insert (-1)" messages to snmpd.log when it reloads its configuration file
(such as when the daemon is restarted). (BZ#468147)

• the snmpd daemon no longer reports the following errors to syslog when

walking through diskIOTable: "diskio.c: don't know how to handle [x]
request". (BZ#474093)

• the net-snmp packages were upgraded to upstream version 5.3.2.2 for Red

Hat Enterprise Linux 5.3. This update changed the format for the snmpd
daemon's "-LS [level] [facility]" logging options by removing the required
space from between the [level] and [facility] arguments. These updated
packages now support both the old-style "-LS" option formatting (space
between arguments) and the new-style (space-less) formatting. (BZ#477768)

• the snmpd daemon contained several memory leaks which occurred when

accessing the Stream Control Transmission Protocol Management Information
Base (SCTP-MIB). These memory leaks have been fixed with these updated
packages.
(BZ#497280)

• the net-snmp-devel package contained an undeclared dependency on the

lm_sensors-devel package, which has been made explicit with this update.
(BZ#437819)

In addition, the following new Object IDs (OIDs) have been implemented in
the snmpd daemon:

• RMON-MIB::etherStatsJabbers and ETHERLIKE-MIB:dot3StatsTable. The

implementation of these OIDs is limited to systems with a Broadcom BCM 5708
Gigabit Ethernet Controller or an Intel Corporation 82541GI Gigabit
Ethernet Controller. (BZ#468832)

• IP-MIB::ipAddressSpinLock, which allows the synchronization of ipTable

modifications. (BZ#479609)

• IP-MIB::ipNetToPhysicalLastUpdated, which details when a

ipNetToPhysicalTable was created or last updated. (BZ#477092)

All SNMP users are advised to upgrade to these updated net-snmp packages,
which resolve these issues and add these enhancements.
