[TCP] Core dumped when SIGTERM received after probing tcp port #188

Closed sirK84 closed 7 years ago

sirK84 commented 7 years ago

Hi,

I've found another issue:

Problem description: Core is dumped from ipfixcol (probably within ipfixcol-tcp-input.so) when program is requested to terminate, after checking ipfix port with nmap.

Ipfixcol version: 0.9.3 buildID: 520399

Test scenario

  1. start ipfixcol with tcp input plugin: $ ipfixcol -s -v3

  2. probe ipfix port e.g. with nmap: $ nmap -p 4739 127.0.0.1 Starting Nmap 7.01 ( https://nmap.org ) at 2017-06-09 11:25 CEST Nmap scan report for localhost (127.0.0.1) Host is up (0.00022s latency). PORT STATE SERVICE 4739/tcp open unknown Nmap done: 1 IP address (1 host up) scanned in 0.04 seconds

  3. terminate ipfixcol with either Ctrl + C or kill command: $ kill -15

Expected result: ipfixcol process terminates gracefully

Actual result: ipfixcol process terminates with core dump:

$ ipfixcol -s -v3

Hi,

This issue was fixed in commit 6df2fc261730327a3411332df56ad2ddd025617d but I did not build a new package for it yet. I'll do that next week and update this issue.

Thanks for your patience

No problem, you could not have known that some devel release fixed this. Anyway, IPFIXcol 0.9.4 is released now including COPR packages and it includes the bugfix as well.
