Module: sip-router Branch: 3.1 Commit: 6d0fa20ec53c361600c84d5322c54a402256fb75 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=6d0fa20… Author: Daniel-Constantin Mierla <miconda(a)gmail.com> Committer: Daniel-Constantin Mierla <miconda(a)gmail.com> Date: Thu Nov 25 22:25:01 2010 +0100 permissions(k): changed params from PVAR to SPVE type - type of fixup params for allow_trusted() updated from PVAR to SPVE - PVAR can be non-zero terminated string - SPVE accepts also static string or combination of PVs - adapted patch submitted by Alex Hermann for crash related to static protocol value, FS#102 (cherry picked from commit 18e67ca2d125f87b85c00eb74b057b9c010a8a26) --- modules_k/permissions/permissions.c | 4 +- modules_k/permissions/trusted.c | 77 +++++++++++++++++------------------ 2 files changed, 39 insertions(+), 42 deletions(-) diff --git a/modules_k/permissions/permissions.c b/modules_k/permissions/permissions.c index 4d41817..5beb016 100644 --- a/modules_k/permissions/permissions.c +++ b/modules_k/permissions/permissions.c @@ -129,8 +129,8 @@ static cmd_export_t cmds[] = { REQUEST_ROUTE | FAILURE_ROUTE}, {"allow_trusted", (cmd_function)allow_trusted_0, 0, 0, 0, REQUEST_ROUTE | FAILURE_ROUTE}, - {"allow_trusted", (cmd_function)allow_trusted_2, 2, fixup_pvar_pvar, - fixup_free_pvar_pvar, REQUEST_ROUTE | FAILURE_ROUTE}, + {"allow_trusted", (cmd_function)allow_trusted_2, 2, fixup_spve_spve, + fixup_free_spve_spve, REQUEST_ROUTE | FAILURE_ROUTE}, {"allow_uri", (cmd_function)allow_uri, 2, double_fixup, 0, REQUEST_ROUTE | FAILURE_ROUTE|LOCAL_ROUTE}, {"allow_address", (cmd_function)allow_address, 3, fixup_igp_pvar_pvar, diff --git a/modules_k/permissions/trusted.c b/modules_k/permissions/trusted.c index 77545ad..33cae33 100644 --- a/modules_k/permissions/trusted.c +++ b/modules_k/permissions/trusted.c @@ -35,6 +35,7 @@ #include "../../config.h" #include "../../lib/srdb1/db.h" #include "../../ip_addr.h" +#include "../../mod_fix.h" #include "../../mem/shm_mem.h" #include "../../parser/msg_parser.h" #include "../../parser/parse_from.h" @@ -462,51 +463,47 @@ int allow_trusted_0(struct sip_msg* _msg, char* str1, char* str2) */ int allow_trusted_2(struct sip_msg* _msg, char* _src_ip_sp, char* _proto_sp) { - pv_spec_t *src_ip_sp, *proto_sp; - pv_value_t pv_val; - char *src_ip, *proto; + str src_ip, proto; int proto_int; - src_ip_sp = (pv_spec_t *)_src_ip_sp; - proto_sp = (pv_spec_t *)_proto_sp; - - if (src_ip_sp && (pv_get_spec_value(_msg, src_ip_sp, &pv_val) == 0)) { - if (pv_val.flags & PV_VAL_STR) { - src_ip = pv_val.rs.s; - } else { - LM_ERR("src_ip pvar value is not string\n"); - return -1; - } - } else { - LM_ERR("src_ip pvar does not exist or has no value\n"); - return -1; + if (_src_ip_sp==NULL + || (fixup_get_svalue(_msg, (gparam_p)_src_ip_sp, &src_ip) != 0)) { + LM_ERR("src_ip param does not exist or has no value\n"); + return -1; } - if (proto_sp && (pv_get_spec_value(_msg, proto_sp, &pv_val) == 0)) { - if (pv_val.flags & PV_VAL_STR) { - strlower(&(pv_val.rs)); - proto = pv_val.rs.s; - } else { - LM_ERR("proto pvar value is not string\n"); - return -1; - } - } else { - LM_ERR("proto pvar does not exist or has no value\n"); - return -1; + if (_proto_sp==NULL + || (fixup_get_svalue(_msg, (gparam_p)_proto_sp, &proto) != 0)) { + LM_ERR("proto param does not exist or has no value\n"); + return -1; } - - if (strcmp(proto, "udp") == 0) { - proto_int = PROTO_UDP; - } else if (strcmp(proto, "tcp") == 0) { - proto_int = PROTO_TCP; - } else if (strcmp(proto, "tls") == 0) { - proto_int = PROTO_TLS; - } else if (strcmp(proto, "sctp") == 0) { - proto_int = PROTO_SCTP; - } else { - LM_ERR("unknown protocol %s\n", proto); - return -1; + if(proto.len!=3 && proto.len!=4) + goto error; + + switch(proto.s[0]) { + case 'u': case 'U': + if (proto.len==3 && strncasecmp(proto.s, "udp", 3) == 0) { + proto_int = PROTO_UDP; + } else goto error; + break; + case 't': case 'T': + if (proto.len==3 && strncasecmp(proto.s, "tcp", 3) == 0) { + proto_int = PROTO_TCP; + } else if (proto.len==3 && strncasecmp(proto.s, "tls", 3) == 0) { + proto_int = PROTO_TLS; + } else goto error; + break; + case 's': case 'S': + if (proto.len==4 && strncasecmp(proto.s, "sctp", 4) == 0) { + proto_int = PROTO_SCTP; + } else goto error; + break; + default: + goto error; } - return allow_trusted(_msg, src_ip, proto_int); + return allow_trusted(_msg, src_ip.s, proto_int); +error: + LM_ERR("unknown protocol %.*s\n", proto.len, proto.s); + return -1; }
