In the stable 5.4 (tested on an "emerge-webrsync" on 2007.05.07) release of net-snmp, there is a bug where some memory from "netsnmp_udp_transport" is not freed. net-snmp claims to have fixed this bug in a current build. Can the package be updated or at least marked as unstable? (Valgrind example): ==23482== 20 bytes in 1 blocks are definitely lost in loss record 5 of 16 ==23482== at 0x4A1FB80: malloc (in /usr/lib64/valgrind/amd64-linux/vgpreload_memcheck.so) ==23482== by 0x4DEFEEA: netsnmp_udp_transport (in /usr/lib64/libnetsnmp.so.15.0.0) ==23482== by 0x4DF03E9: netsnmp_udp_create_tstring (in /usr/lib64/libnetsnmp.so.15.0.0) ==23482== by 0x4DED1C4: netsnmp_tdomain_transport_full (in /usr/lib64/libnetsnmp.so.15.0.0) ==23482== by 0x4DCDFA6: snmp_sess_open (in /usr/lib64/libnetsnmp.so.15.0.0) From this site: www.mail-archive.com/net-snmp-coders@lists.sourceforge.net/msg09641.html ---- This is a bug.

I built 5.4.1 separately, and it removed the issue. I am emerging net-snmp again (I've done this at least three times now) to see if there's something that I'm missing. Could there possibly be a USE flag that is the problem? doug.manley@gmail.com 2007-11-13 15:49:14 0000 All right. It seems to work perfectly fine now.

All right, we did some hardcore tests (finally), and we have the results. There IS still a memory leak in net-snmp 5.4.1-r1, and we know where and why and how. Basically, the net-snmp 5.4.1 distribution is perfectly fine. However, the patch that gentoo installs for the "clientaddr" fix is what creates the leak. The patch provides some better debug output in one of the internal functions (among other things). What it also does is a "strdup" in an "sprintf" command in the variables section, which is very, very bad (as there is now no pointer to the address that "strdup" put its output in--so it can't be "free"d). What's really strange is that there is a comment about "strdup" being very important.

It has the exact same functionality as the current one, but it does not leak. This does not do unnecessary "strdup" operations, and it frees the ones that it does do. If there is a reason for the "strdup" sprinkling all over the patch, it is not apparent. "strdup" should only be necessary for preventing the buffer from being overwritten by two successive calls in the "sprintf". doug.manley@gmail.com 2007-11-20 18:01:06 0000 Created an attachment (id=136513) This is the patched snmpUDPDomain.c file.
