Hi Roger,
>From looking at what wasn't freed, I'm guessing that you had a failure
in the pcap compile, etc.
The error exits in that code didn't free things up properly.
==28727== 110 bytes in 1 blocks are definitely lost in loss record 35 of 59
==28727== at 0x4C2B3F8: malloc (in
/usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
==28727== by 0x4E3ED16: create_pcap_listener (pcap_min.c:104)
==28727== by 0x4E3F683: g_source_pcap_new (pcap_GSource.c:124)
==28727== by 0x4E42EE8: switchdiscovery_new (switchdiscovery.c:133)
==28727== by 0x4E4C652: nano_start_full (nanoprobe.c:986)
Here's the malloc code (at line 104 above):
if (NULL == (*expr* = malloc(filterlen))) {
g_error("Out of memory!");
return NULL;
}
Since the non-failure case looks like this:
DEBUGMSG1("Compile of [%s] worked!\n", expr);
free(*expr*); expr = *NULL*;
return(pcdescr);
then it's reasonable to assume that your invocation didn't go through that
return case.
So I put this error exit code in:
oopsie: // Some kind of failure - free things up and return NULL
if (expr) {
free(expr);
expr = NULL;
}
if (pcdescr) {
close_pcap_listener(pcdescr, dev, listenmask);
pcdescr = NULL;
}
return NULL;
Along with ensuring that expr and pcdescr initialized to NULL.
There may also be other issues. But that one seems clear...
