1.151.  net-snmp

1.151.1.  RHBA-2009:1215: bug fix update

Note

This update has already been released (prior to the GA of this release) as errata RHBA-2009:1215
Updated net-snmp packages that resolve an issue are now available.
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 fix the following bug:
  • snmpd, the SNMP daemon, did not expect the packet counters in the /proc/net/snmp and /proc/net/snmp6 files to be 64-bit on 64-bit systems. When these counters exceeded 32 bits in size, which would occur when the Linux kernel sent or received greater than 4,294,967,296 (2^32) packets, then the snmpd daemon would terminate abnormally. With this update, the snmpd daemon no longer crashes when it encounters a packet counter in the directories listed above that is greater than 32 bits in size, thus resolving the issue. (BZ#516182)
All users of net-snmp are advised to upgrade to these updated packages, which resolve this issue.

1.151.2.  RHBA-2009:1069: bug fix update

Note

This update has already been released (prior to the GA of this release) as errata RHBA-2009:1069
Updated net-snmp packages that resolve an issue are now available.
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 fix the following bug:
  • snmpd, the SNMP daemon, contained several memory leaks. These leaks caused snmpd to leak memory relatively slowly but significantly, at the rate of 50 MB per month. These memory leaks have been plugged in these updated packages, and snmpd no longer leaks memory over time. (BZ#497810)
All users of net-snmp are advised to upgrade to these updated packages, which resolve this issue.

1.151.3.  RHBA-2009:1372: enhancement and bug fix update

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