Module: sip-router Branch: kamailio_3.0 Commit: a1b15f1289db84bdf8e3da11fa33af9ae0501f3c URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=a1b15f1… Author: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Committer: Daniel-Constantin Mierla <miconda(a)gmail.com> Date: Mon Dec 14 13:00:07 2009 +0100 core: fix parsing for avps with the same name as a pv class When a pv lookup fails, sometimes the pvspec is partially filled which, if not clean might mess-up the avp flags in the lval union. E.g.: $avp="..." caused problems (avp was marked as RE name). --- cfg.y | 4 ++++ 1 files changed, 4 insertions(+), 0 deletions(-) diff --git a/cfg.y b/cfg.y index 2c488a2..0062b0e 100644 --- a/cfg.y +++ b/cfg.y @@ -2435,6 +2435,10 @@ avp_pvar: AVP_OR_PVAR { s_tmp.s=$1; s_tmp.len=strlen(s_tmp.s); if (pv_parse_spec2(&s_tmp, &lval_tmp->lv.pvs, 1)==0){ /* not a pvar, try avps */ + /* lval_tmp might be partially filled by the failed + pv_parse_spec2() (especially if the avp name is the + same as a pv class) => clean it again */ + memset(lval_tmp, 0, sizeof(*lval_tmp)); lval_tmp->lv.avps.type|= AVP_NAME_STR; lval_tmp->lv.avps.name.s.s = s_tmp.s+1; lval_tmp->lv.avps.name.s.len = s_tmp.len-1;
