We try to collect significant open issues for the upcoming 5.4.2 release cycle here. Please add your contributions/comments and fix as much as you can!
Open issues for 5.4.2
| Nr | Issue | Bug/patch | Comment | Assigned to |
| 1 | ipAddressTable crashes with double free | Bugs 1733344, 1794532, 1857628 | Crashes with double free. Full story below. | rstory |
| 2 | error on subcontainer 'ia_addr' insert (-1) | Bug 1693039, Patch 1712645 | Provide a more meaningful log message for duplicate IP addresses instead of spamming the log continuously. | rstory? |
| 3 | set O_NONBLOCK on Linux! | Bug 1718296 | recvfrom can block if we don't set O_NONBLOCK on Linux | ? |
| 4 | HP-UX 11.23/IA64 build failure | Bug 1742278 | Build fails in snmplib/system.c. Preprocessor output available. | tanders/magfr? |
| 5 | hrStorageSize overflow | Bug 1743171 | hrStorageSize is negative for large filesystems, although the MIB only allows values >=0. | ? |
| 6 | ifTable transient interface handling | Bug 1238981, Patch 1513191 | offer an (per-interface) config option how transient interfaces are handled in ifTable (same or different). A List FAQ. This feels like a new feature, and not appropriate for 5.4.x? |
rstory? |
| 7 | Suppress error messages on SIGHUP | ? | Remove the likely harmless, but annoying error messages on SIGHUP. A List FAQ Handled for "extend" and "monitor" directives. What others? |
? |
| 8 | disman/event crash | Bug 1556259 | Reported crashes in mteTrigger.c This is a race condition between (typically high-volume) request handling and trap generation. Not realistic to address for 5.4.2? |
dts12 |
| 9 | Solaris perl<->host issues (due to largefiles) | Bug 1486366 | Solaris system-supplied Perl is compiled with largefile support. The very same options break the build of the host module, though. At least detected (and embedded perl disabled) since 5.4.pre3. |
? |
| 10 | 64bit nlist | Bugs 148532, 1484814, 1388562 | nlist fails on 64bit systems (AIX, IRIX, Tru64). We need 64bit capable auto_nlist replacement routines. Every system has its own variant and changes are needed all over the net-snmp code. Stop-gap fix is specifying --without-kmem-usage which is possible since 5.4.rc2. | tanders |
