Hi all, I am evaluating porting the Net-SNMP (5.2.1) to a thread environment platform.
Only one thread of SNMP agent will run at the time.
However stopping and starting the SNMP agent is a requirement.
When I look at the code in snmpd.cxx I see:
receive();
#include "mib_module_shutdown.h"
DEBUGMSGTL(("snmpd/main", "sending shutdown trap\n"));
SnmpTrapNodeDown();
DEBUGMSGTL(("snmpd/main", "Bye...\n"));
snmp_shutdown("snmpd");
#ifdef SHUTDOWN_AGENT_CLEANLY /* broken code */
/* these attempt to free all known memory, but result in double frees */
shutdown_master_agent();
shutdown_agent();
#endif
A few questions:
Is it safe to use the code under SHUTDOWN_AGENT_CLEANLY to shutdown the agent?
Will it successfully clean all the memory and resources allocated? (like the open sockets for instance...)
If the code is really broken as the comments states what will it take to fix it?
Thanks for your help!
