[Bug 997217] Re: salsauthd maxes cpu

[Andreas Hasenack]

xenial verification

Confirming bug:

ubuntu at xenial-saslauthd:~$ apt-cache policy sasl2-bin
sasl2-bin:
  Installed: 2.1.26.dfsg1-14build1
  Candidate: 2.1.26.dfsg1-14build1
  Version table:
 *** 2.1.26.dfsg1-14build1 500
        500 http://br.archive.ubuntu.com/ubuntu xenial/main amd64 Packages


Confirmed saslauthd at 100% CPU after the test command:
  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND                                                                                                                                        
 6666 root      20   0   90860    972      0 R 100.0  0.0   0:05.72 saslauthd              


subsequent testsaslauthd commands just block, as expected due to the bug.


Repeating the test with the package from proposed:
ubuntu at xenial-saslauthd:~$ apt-cache policy sasl2-bin
sasl2-bin:
  Installed: 2.1.26.dfsg1-14ubuntu0.1
  Candidate: 2.1.26.dfsg1-14ubuntu0.1
  Version table:
 *** 2.1.26.dfsg1-14ubuntu0.1 500
        500 http://br.archive.ubuntu.com/ubuntu xenial-proposed/main amd64 Packages

Not only does saslauthd not start eating cpu, it keeps working:
with dovecot stopped:
ubuntu at xenial-saslauthd:~$ sudo testsaslauthd -u ubuntu -p ubuntu
0: NO "authentication failed"

Starting up dovecot and trying again:
ubuntu at xenial-saslauthd:~$ sudo service dovecot start
ubuntu at xenial-saslauthd:~$ sudo testsaslauthd -u ubuntu -p ubuntu
0: OK "Success."
ubuntu at xenial-saslauthd:~$
