Hi elunlen,
Can you please give more clarification on this ticket as requested by Krishna.
I have ran valgrind on smf and discovered memory leak errors. However, the
errors are not in the area suspected by elunlen. However, the absence of
valgrind reported errors in the area indicated by elunlen is not the evidence
that there is no possible memory leak.
Following are examples of valgrind reported memory leak
==335== 53 bytes in 1 blocks are definitely lost in loss record 1 of 2
==335== at 0x4C2DB8F: malloc (in
/usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
==335== by 0x527ADAC: daemonize (daemon.c:295)
==335== by 0x109817: main (smfnd_main.c:223)
==335==
==335== LEAK SUMMARY:
==335== definitely lost: 53 bytes in 1 blocks
==335== indirectly lost: 0 bytes in 0 blocks
==335== possibly lost: 0 bytes in 0 blocks
==335== still reachable: 72,704 bytes in 1 blocks
==335== suppressed: 0 bytes in 0 blocks
==335== Reachable blocks (those to which a pointer was found) are not shown.
==335== To see them, rerun with: --leak-check=full --show-leak-kinds=all
==335== 53 bytes in 1 blocks are definitely lost in loss record 1 of 2
==335== at 0x4C2DB8F: malloc (in
/usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
==335== by 0x64DADAC: daemonize (daemon.c:295)
==335== by 0x13C74D: main (smfd_main.cc:463)
Other leaks will be updated to this ticket.
Best Regards,
Thanh

Need to clean up the cb->cbk_list, otherwise there will be memory leak. For the
time being we are storing only count of agents, not the adest of agents and
hence it is not possible to clean up cbk_list.
