Bug ID: 213411
Summary: freebsd-update does not form a valid MLIST when host
-t srv returns non caps reply
Product: Base System
Version: 10.2-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: bin

Patch that just makes the sed statement case insensitive.
freebsd-update fetch fails to find a valid mirror list on some FreeBSD systems
(tested with 10.1-RELEASE and 10.2-RELEASE), by returning:
Looking up update.FreeBSD.org mirrors... none found.
Fetching metadata signature for 10.2-RELEASE from update.FreeBSD.org...
Reason:
Depending on the DNS server a FreeBSD box asks, the answer to a query like:
host -tsrv _http._tcp.update.FREEBSD.org
can be either:
_http._tcp.update.freebsd.org has SRV record 1 5 80 update3.freebsd.org.
_http._tcp.update.freebsd.org has SRV record 1 50 80 update5.freebsd.org.
_http._tcp.update.freebsd.org has SRV record 1 35 80 update4.freebsd.org.
_http._tcp.update.freebsd.org has SRV record 1 40 80 update6.freebsd.org.
or:
_http._tcp.update.FREEBSD.org has SRV record 1 50 80 update5.freebsd.org.
_http._tcp.update.FREEBSD.org has SRV record 1 40 80 update6.freebsd.org.
_http._tcp.update.FREEBSD.org has SRV record 1 5 80 update3.freebsd.org.
_http._tcp.update.FREEBSD.org has SRV record 1 35 80 update4.freebsd.org.
freebsd-update script forms a list of available mirror servers by executing
such a query and by running various sed commands on its output. If the reply
does not contain FREEBSD in caps, the produced list turns out to be empty -
which is wrong, since the reply is not empty (and since FQDNs are case
insensitive). This happens because the SERVERNAME variable of freebsd-update
takes its value (update.FREEBSD.org) from /etc/freebsd-update.conf, which has
caps in it.
It's strange that some DNS servers reply with caps when asked with caps and
others don't, but this is a different issue...
A patch that makes the sed statement case insensitive is provided. Another
possible patch that would resolve the issue would be to change
/etc/freebsd-update.conf's record to use lower case, but IMHO, the script is
wrong because FQDNs are case insensitive and it doesn't take it into account.
