URL: <https://savannah.nongnu.org/bugs/?55960> Summary: SNMP MIB compiler/code generator does not always parse SIZE for textual conventions Project: lwIP - A Lightweight TCP/IP stack Submitted by: inojosh Submitted on: Tue 19 Mar 2019 11:25:29 PM UTC Category: apps Severity: 3 - Normal Item Group: Faulty Behaviour Status: None Privacy: Public Assigned to: None Open/Closed: Open Discussion Lock: Any Planned Release: None lwIP version: git head _______________________________________________________ Details: When the MIB compiler generates "_scalars_set_test" functions, it doesn't always parse the SIZE for textual conventions. It does parse the SIZE for a TEXTUAL-CONVENTION that contains SIZE. It does not parse the SIZE when added onto an existing TEXTUAL-CONVENTION. Examples: A working example would be a MIB object with: SYNTAX DisplayString Will generate the test: if (((len >= 0) && (len <= 255))) { err = SNMP_ERR_NOERROR; } Which is correct since it parses the SIZE for DisplayString from SNMPv2-TC. But a MIB object with: SYNTAX DisplayString (SIZE (0..64)) Will generate NO test, just: err = SNMP_ERR_NOERROR; _______________________________________________________ Reply to this item at: <https://savannah.nongnu.org/bugs/?55960> _______________________________________________ Message sent via Savannah https://savannah.nongnu.org/
