Ulrich Weber 350daa1248 netfilter: nf_conntrack_sip: extend request line validation ...

commit 444f901742 upstream.

on SIP requests, so a fragmented TCP SIP packet from an allow header starting with
 INVITE,NOTIFY,OPTIONS,REFER,REGISTER,UPDATE,SUBSCRIBE
 Content-Length: 0

will not bet interpreted as an INVITE request. Also Request-URI must start with an alphabetic character.

Confirm with RFC 3261
 Request-Line   =  Method SP Request-URI SP SIP-Version CRLF

Fixes: 30f33e6dee ("[NETFILTER]: nf_conntrack_sip: support method specific request/response handling")
