Hello! Thanks for your work with creating and testing the patch. When Xenial Fix will be released?
I'd love to see it, because activation of Proposed repo on dozens hosts does not looks very good.

It was triggared by use uninitialized variable in pam_tty_audit.c::pam_open_session. [Test Case] 1) Open a shell & escalate to root 2) Update /etc/pam.d/common-session & /etc/pam.d/common-session-noninteractive and add the following line directly after the line: "session required pam_unix.so": "session required pam_tty_audit.so enable=*" 3) Start a second new shell session on the box and type a variety of commands 4) Exit the second shell session to flush the buffer? 5) In the root shell run "aureport -tty -i". The output should show the commands run in the other shell. [Regression Potential] * Low, we are simply including the missing header file and copy the old status as initialization of new. The fix is already found/part of Debian and Disco. [Pending SRU] All regressions found in Bionic and Cosmic looks like long standing ADT failure. Nothing has been introduce by this particular SRU.

I found a bug in pam_tty_audit. When Using the pam_tty_audit with other pam modules(ex, pam_ldap), it failed in pam_open_session. It was triggared by use uninitialized variable in pam_tty_audit.c::pam_open_session. * Enviroments Ubuntu 14.04.4 LTS linux-image-3.16.0-71-generic 3.16.0-71.92~14.04.1 libpam-ldap:amd64 184-8.5ubuntu3 libpam-modules:amd64 1.1.8-1ubuntu2.2 Ubuntu 16.04.2 TLS linux-image-4.4.0-62-generic 4.4.0-62.83 libpam-ldap:amd64 184-8.7ubuntu1 libpam-modules:amd64 1.1.8-3.2ubuntu2 * Reproduction method 1. Install libpam-ldap. 2. Add the following to the end of /etc/pam.d/common-sessions -------- session required pam_tty_audit.so enable=* open_only -------- 3. When logging in with ssh etc., pam_tty_audit will fail and login fails * Solution (== 2018/04/16 Link updated ==) apply upstream patch https://github.com/linux-pam/linux-pam/commit/c5f829931a22c65feffee16570efdae036524bee * Logs (on Ubuntu14.04) -- auth.log -- May 18 14:47:03 vm sshd[2272]: Accepted publickey for test from 10.99.0.1 port 51398 ssh2: RSA 8f:39:1c:3a:f4:9d:ca:99:67:fc:e3:fd:1e:0c:5b:a8 May 18 14:47:03 vm sshd[2272]: pam_unix(sshd:session): session opened for user test by (uid=0) May 18 14:47:03 vm sshd[2272]: pam_tty_audit(sshd:session): error setting current audit status: Invalid argument May 18 14:47:03 vm sshd[2272]: error: PAM: pam_open_session(): Cannot make/remove an entry for the specified session May 18 14:47:03 vm sshd[2297]: Received disconnect from 10.99.0.1: 11: disconnected by user -- syslog -- May 18 14:47:03 vm audispd: node=vm type=USER_ACCT msg=audit(1463550423.399:58): pid=2272 uid=0 auid=4294967295 ses=4294967295 msg='op=PAM:accounting acct="test" exe="/usr/sbin/sshd" hostname=10.99.0.1 addr=10.99.0.1 terminal=ssh res=success' May 18 14:47:03 vm audispd: node=vm type=CRED_ACQ msg=audit(1463550423.403:59): pid=2272 uid=0 auid=4294967295 ses=4294967295 msg='op=PAM:setcred acct="test" exe="/usr/sbin/sshd" hostname=10.99.0.1 addr=10.99.0.1 terminal=ssh res=success' May 18 14:47:03 vm audispd: node=vm type=LOGIN msg=audit(1463550423.403:60): pid=2272 uid=0 old-auid=4294967295 auid=20299 old-ses=4294967295 ses=3 res=1 May 18 14:47:03 vm audispd: node=vm type=CONFIG_CHANGE msg=audit(1463550423.403:61): pid=2272 uid=0 auid=20299 ses=3 op=tty_set old-enabled=0 new-enabled=1 old-log_passwd=0 new-log_passwd=32743 res=0 May 18 14:47:03 vm audispd: node=vm type=USER_START msg=audit(1463550423.447:62): pid=2272 uid=0 auid=20299 ses=3 msg='op=PAM:session_open acct="test" exe="/usr/sbin/sshd" hostname=10.99.0.1 addr=10.99.0.1 terminal=ssh res=failed' May 18 14:47:03 vm audispd: node=vm type=CRED_ACQ msg=audit(1463550423.447:63): pid=2297 uid=0 auid=20299 ses=3 msg='op=PAM:setcred acct="test" exe="/usr/sbin/sshd" hostname=10.99.0.1 addr=10.99.0.1 terminal=ssh res=success' May 18 14:47:03 vm audispd: node=vm type=CRED_DISP msg=audit(1463550423.451:64): pid=2272 uid=0 auid=20299 ses=3 msg='op=PAM:setcred acct="test" exe="/usr/sbin/sshd" hostname=10.99.0.1 addr=10.99.0.1 terminal=ssh res=success' Thanks regards.
