[sr-dev] git:kamailio_3.0: tls: fix wrong string variable length overwrite

Module: sip-router Branch: kamailio_3.0 Commit: 32361f710b1d66723a22c10bee0bb6088867c681 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=32361f7… Author: Andrei Pelinescu-Onciul &lt;andrei(a)iptel.org&gt; Committer: Andrei Pelinescu-Onciul &lt;andrei(a)iptel.org&gt; Date: Tue Sep 7 16:57:33 2010 +0200 tls: fix wrong string variable length overwrite Some per-domain config string variables (cert_file, ca_file, pkey_file & cipher_list) had their length truncated to that of the corresponding variable in the parent domain. Mostly invisible since the string length was in general ignored (asciiz strings).
