Issue ID: 9445
Summary: ITS#9339/1748ec59a crashes slapd on ip connect in
tcpwrappers
Product: OpenLDAP
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: ---
Component: slapd
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
When openldap is configured with tcpwrappers,
servers/slapd/daemon.c`slap_listener() calls:
> hosts_ctl("slapd", dnsname != NULL ? dnsname : SLAP_STRING_UNKNOWN,
> peeraddr, ...
where `peeraddr' must be client ip addr or literal "unknown" string.
Commit [2020-09-06 1748ec59a ITS#9339 Add syncrepl status to cn=monitor] is
made so that `peeraddr' contains fixed NULL value.
This causes immediate crash of slapd inside tcpwrappers library when client
connects using ip protocol at least on Solaris x86-64.
I did not verify this on linux, but even if slapd doesn't crash on linux, then
tcpwrappers do not work as expected anyway.
