git:master: core: fix end-script commands in expr. leaks

by Andrei Pelinescu-Onciul

Module: sip-router Branch: master Commit: 28a882873f8a69a189d790e33bcd2017c253a66a URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=28a8828… Author: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Committer: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Date: Wed Sep 29 16:30:40 2010 +0200 core: fix end-script commands in expr. leaks When having commands that end the script immediately in assignments (e.g. $foo = { drop; }) or in expressions (e.g. if ($v + { drop; } > 0)), the script was terminated immediately via longjmp. However this might leave some un-freed variables. This fix introduces a safe version of run_actions() (run_actions_safe()) that will not use longjmp() to immediately end the whole script on drop, returning instead to its caller. --- action.c | 30 +++++++++++++++++++++++++++++- action.h | 8 ++++++++ lvalue.c | 4 ++-- route_struct.h | 1 + rvalue.c | 4 ++-- 5 files changed, 42 insertions(+), 5 deletions(-) diff --git a/action.c b/action.c index dd0cfef..1716c34 100644 --- a/action.c +++ b/action.c @@ -1564,7 +1564,8 @@ int run_actions(struct run_act_ctx* h, struct action* a, struct sip_msg* msg) h->rec_lev--; end: /* process module onbreak handlers if present */ - if (unlikely(h->rec_lev==0 && ret==0)) + if (unlikely(h->rec_lev==0 && ret==0 && + !(h->run_flags & IGNORE_ON_BREAK_R_F))) for (mod=modules;mod;mod=mod->next) if (unlikely(mod->exports.onbreak_f)) { mod->exports.onbreak_f( msg ); @@ -1578,6 +1579,33 @@ error: } + +#ifdef USE_LONGJMP +/** safe version of run_actions(). + * It always return (it doesn't longjmp on forced script end). + * @returns 0, or 1 on success, <0 on error + * (0 if drop or break encountered, 1 if not ) */ +int run_actions_safe(struct run_act_ctx* h, struct action* a, + struct sip_msg* msg) +{ + struct run_act_ctx ctx; + int ret; + int ign_on_break; + + /* start with a fresh action context */ + init_run_actions_ctx(&ctx); + ctx.last_retcode = h->last_retcode; + ign_on_break = h->run_flags & IGNORE_ON_BREAK_R_F; + ctx.run_flags = h->run_flags | IGNORE_ON_BREAK_R_F; + ret = run_actions(&ctx, a, msg); + h->last_retcode = ctx.last_retcode; + h->run_flags = (ctx.run_flags & ~IGNORE_ON_BREAK_R_F) | ign_on_break; + return ret; +} +#endif /* USE_LONGJMP */ + + + int run_top_route(struct action* a, sip_msg_t* msg, struct run_act_ctx *c) { struct run_act_ctx ctx; diff --git a/action.h b/action.h index c11baa9..a2a5395 100644 --- a/action.h +++ b/action.h @@ -68,4 +68,12 @@ int run_actions(struct run_act_ctx* c, struct action* a, struct sip_msg* msg); int run_top_route(struct action* a, sip_msg_t* msg, struct run_act_ctx* c); + +#ifdef USE_LONGJMP +int run_actions_safe(struct run_act_ctx* c, struct action* a, + struct sip_msg* msg); +#else /*!
