Subject: [PATCH] Fix: libcrmcluster: prevent external callers from triggering
|
|
assertion when connecting to cluster
|
|
|
|
When sbd is connecting to cluster by calling crm_cluster_connect() ->
|
|
pcmk_cluster_connect() -> pcmk__corosync_connect() ->
|
|
pcmk__cpg_connect() -> pcmk__server_message_type()
|
|
|
|
, it triggers assertion:
|
|
|
|
error: log_assertion_as: pcmk__server_message_type: Triggered fatal
|
|
assertion at servers.c:165 : (server > 0) && (server <
|
|
PCMK__NELEM(server_info))
|
|
|
|
This fixes it by avoiding calling pcmk__server_message_type() in
|
|
pcmk__cpg_connect().
