Module: sip-router Branch: 3.1 Commit: 7310ba9d6c808dc932fe1e925b9e36e57f6b473e URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=7310ba9… Author: Daniel-Constantin Mierla <miconda(a)gmail.com> Committer: Daniel-Constantin Mierla <miconda(a)gmail.com> Date: Sun Feb 27 16:43:06 2011 +0100 kcore: supported header exports the free function in parsed structure - parsing the supported header creates a structure allocated in PKG, now it exports the function to free it in order to be used when cleaning the SIP message structure - this fixes a memory leak when parsing the header - reported and troubleshooted by Bayan Towfiq (cherry picked from commit 9a668406925abf19cbae62c98a12b86f4c045b34) --- lib/kcore/parse_supported.c | 21 +++++++++++++++++++++ lib/kcore/parse_supported.h | 10 +++------- 2 files changed, 24 insertions(+), 7 deletions(-) diff --git a/lib/kcore/parse_supported.c b/lib/kcore/parse_supported.c index 8720397..8c81cfb 100644 --- a/lib/kcore/parse_supported.c +++ b/lib/kcore/parse_supported.c @@ -112,6 +112,17 @@ static inline int parse_supported_body(str *body, unsigned int *sup) return 0; } + +/** + * wrapper to free the content of parsed supported header + */ +void hf_free_supported(void *parsed) +{ + struct supported_body *sb; + sb = (struct supported_body*)parsed; + free_supported(&sb); +} + /*! * Parse all Supported headers */ @@ -144,6 +155,7 @@ int parse_supported( struct sip_msg *msg) } parse_supported_body(&(hdr->body), &(sb->supported)); + sb->hfree = hf_free_supported; sb->supported_all = 0; hdr->parsed = (void*)sb; supported |= sb->supported; @@ -153,3 +165,12 @@ int parse_supported( struct sip_msg *msg) supported; return 0; } + +/* free supported header structure */ +void free_supported(struct supported_body **sb) +{ + if (sb && *sb) { + pkg_free(*sb); + *sb = 0; + } +} diff --git a/lib/kcore/parse_supported.h b/lib/kcore/parse_supported.h index 126f56e..55f04f8 100644 --- a/lib/kcore/parse_supported.h +++ b/lib/kcore/parse_supported.h @@ -36,6 +36,7 @@ #define PARSE_SUPPORTED_H #include "../../parser/msg_parser.h" +#include "../../parser/hf.h" #include "../../mem/mem.h" @@ -64,6 +65,7 @@ struct supported_body { + hf_parsed_free_f hfree; /* function to free the content */ unsigned int supported; /* supported mask for the current hdr */ unsigned int supported_all; /* suppoted mask for the all "supported" hdr * - it's set only for the first hdr in @@ -77,12 +79,6 @@ struct supported_body { int parse_supported( struct sip_msg *msg); -static inline void free_supported(struct supported_body **sb) -{ - if (sb && *sb) { - pkg_free(*sb); - *sb = 0; - } -} +void free_supported(struct supported_body **sb); #endif /* PARSE_SUPPORTED_H */
