I *think* this debian commit could possibly be a good candidate to fix Artful FTBFS situation.
------- $ git show a7476dd9 commit a7476dd96e79197f65acf0f049f75ce8e8f9e801 Author: Jan Pokorny <jpoko...@redhat.com> Date: Thu Feb 2 14:51:46 2017 +0100 Fix: crm_mon: protect against non-standard or failing asctime So far, we have been likely covered by standards requiring asctime to produce an output ending with \n\0 bytes, because otherwise, we would overrun the buffer, reading unspecified content, possibly segfaulting. This was actually discovered with a brand new GCC7 warning ( [-Werror=pointer-compare]). Another latent issue was that the code was not ready for the case of failing asctime call (returning NULL). This is now fixed as well. diff --git a/tools/crm_mon.c b/tools/crm_mon.c index 776aea8..023b07b 100644 --- a/tools/crm_mon.c +++ b/tools/crm_mon.c @@ -954,10 +954,10 @@ print_nvpair(FILE *stream, const char *name, const char *value, /* Otherwise print user-friendly time string */ } else { - char *date_str, *c; + static char empty_str[] = ""; + char *c, *date_str = asctime(localtime(&epoch_time)); - date_str = asctime(localtime(&epoch_time)); - for (c = date_str; c != '\0'; ++c) { + for (c = (date_str != NULL) ? date_str : empty_str; *c != '\0'; ++c) { if (*c == '\n') { *c = '\0'; break; ------- I'll give it a try and update the case with the outcome of my test. - Eric -- You received this bug notification because you are a member of Ubuntu High Availability Team, which is subscribed to corosync in Ubuntu. https://bugs.launchpad.net/bugs/1740892 Title: corosync upgrade on 2018-01-02 caused pacemaker to fail Status in OpenStack hacluster charm: Invalid Status in corosync package in Ubuntu: Fix Released Status in pacemaker package in Ubuntu: Fix Released Status in corosync source package in Trusty: Won't Fix Status in pacemaker source package in Trusty: Won't Fix Status in corosync source package in Xenial: In Progress Status in pacemaker source package in Xenial: In Progress Status in corosync source package in Artful: In Progress Status in pacemaker source package in Artful: In Progress Status in corosync source package in Bionic: Fix Released Status in corosync package in Debian: New Bug description: [Impact] When corosync and pacemaker are both installed, a corosync upgrade caused pacemaker to fail. pacemaker will need to be restarted manually to work again, it won't recover by itself. [Test Case] 1) Have corosync (< 2.3.5-3ubuntu2) and pacemaker (< 1.1.14-2ubuntu1.3) installed 2) Make sure corosync & pacemaker are running via systemctl status cmd. 3) Upgrade corosync 4) Look corosync and pacemaker via systemctl status cmd again. You will notice pacemaker is dead (inactive) and doesn't recover, unless a systemctl start pacemaker is done manually. [Regression Potential] Regression potential is low, it doesn't change corosync/pacemaker core functionality. This patch make sure thing goes smoother at the packaging level during a corosync upgrade where pacemaker is installed/involved. This can also be useful in particular in situation where the system has "unattended-upgrades" enable (software upgrades without supervision), and no sysadmin available to start pacemaker manually because this isn't a schedule maintenance.
