crash on attempt to traverse mib nodes
by Jonathan Walker 06 Jun '13

06 Jun '13

Hello, I'm finding that libsmi crashes when I remove every "RFC" mib from "mibs/ietf" directory, and then execute a program which performs the following: 1. Add each directory under "mibs" to the smi path (smiSetPath). 2. Traverse each directory under "mibs", and for each mib found get the module and traverse each node in the module. It tends to crash at attempt to traverse nodes of a mib which uses IMPORTS of an RFC- prefixed mib. Though I understand how missing dependencies could cause problems loading/traversing a mib, I'm not sure I understand why it's crashing and no error logs are present. Thanks, Jonathan ________________________________ This e-mail and any attachments are confidential. If it is not intended for you, please notify the sender, and please erase and ignore the contents.

smidump --format=smiv2 output contains some errors in compliance SYNTAX/WRITE-SYNTAX clauses.

Hello, I just stumbled over the following problem in libsmi 0.4.8 and development trunk-tip rev34557 (as of today). The problem resides in the SYNTAX/WRITE-SYNTAX clauses in COMPLIANCE statements. Instead of a "type" the invalid term "(null)" is present. AFFECTED-MIBS (at least): - BRIDGE-MIB - SNMP-VIEW-BASED-ACM-MIB - ... => grep "(null)" *-MIB EXAMPLE: smidump --format=smiv2 BRIDGE-MIB ... OBJECT dot1dStpPriority SYNTAX (null) (0 | 4096 | 8192 | 12288 | 16384 | 20480 | 24576 | 28672 | 32768 | 36864 | 40960 | 45056 | 49152 | 53248 | 57344 | 61440) ... OBJECT dot1dStpPortPriority SYNTAX (null) (0 | 16 | 32 | 48 | 64 | 80 | 96 | 112 | 128 | 144 | 160 | 176 | 192 | 208 | 224 | 240) BUT: Original BRIDGE-MIB that is distributed w/ libsmi contains: OBJECT dot1dStpPriority SYNTAX Integer32 (0 | 4096 | 8192 | 12288 | 16384 | 20480 | 24576 | 28672 | 32768 | 36864 | 40960 | 45056 | 49152 | 53248 | 57344 | 61440) ... OBJECT dot1dStpPortPriority SYNTAX Integer32 (0 | 16 | 32 | 48 | 64 | 80 | 96 | 112 | 128 | 144 | 160 | 176 | 192 | 208 | 224 | 240) smidump --format=smiv2 SNMP-VIEW-BASED-ACM-MIB ... OBJECT vacmViewTreeFamilyMask WRITE-SYNTAX (null) (SIZE(0)) ... SHOULD-BE (as in original MIB distributed with libsmi): ... OBJECT vacmViewTreeFamilyMask WRITE-SYNTAX OCTET STRING (SIZE(0)) I assume that smidump does not have the info (only a NULL pointer) and just dumps it as textual info. NOTE: "smidiff <ORIGINAL-MIB> <SMIDUMPED-MIB>" does not seem to show a difference (except warnings, ...). Ciao, Jens
