Author: S-P Chan <shihping.c...@gmail.com> Committer: S-P Chan <shihping.c...@gmail.com> Date: 2024-02-14T19:49:10+08:00 db_mysql: libssl thread guard for db_mysql_query (and libmysqlclient) This function is observed to call SSL_read() when compiled with libmysqlclient.so.21 (but not libmariadb.so.3). Apply a thread executor just in case. --- Modified: src/modules/db_mysql/km_dbase.c --- Diff: https://github.com/kamailio/kamailio/commit/1e4236445167d837a89d54ce6bee5ef14aef568e.diff Patch: https://github.com/kamailio/kamailio/commit/1e4236445167d837a89d54ce6bee5ef14aef568e.patch --- diff --git a/src/modules/db_mysql/km_dbase.c b/src/modules/db_mysql/km_dbase.c index 7b65c0a012c..91ace58df5b 100644 --- a/src/modules/db_mysql/km_dbase.c +++ b/src/modules/db_mysql/km_dbase.c @@ -41,6 +41,7 @@ #define KSR_RTHREAD_NEED_4PP #define KSR_RTHREAD_NEED_0P +#define KSR_RTHREAD_NEED_4P5I2P2 #include "../../core/rthreads.h" #include "../../lib/srdb1/db_query.h" #include "../../lib/srdb1/db_ut.h" @@ -348,12 +349,26 @@ int db_mysql_free_result(const db1_con_t *_h, db1_res_t *_r) * \param _r pointer to a structure representing the result * \return zero on success, negative value on failure */ + +/* + * this function observed to invoke SSL_read() under libmysqlclient.so.21 + * but not libmariadb.so.3; apply libssl guard + */ +static int db_mysql_query_impl(const db1_con_t *_h, const db_key_t *_k, + const db_op_t *_op, const db_val_t *_v, const db_key_t *_c, + const int _n, const int _nc, const db_key_t _o, db1_res_t **_r) +{ + return db_do_query(_h, _k, _op, _v, _c, _n, _nc, _o, _r, db_mysql_val2str, + db_mysql_submit_query, db_mysql_store_result); +} + int db_mysql_query(const db1_con_t *_h, const db_key_t *_k, const db_op_t *_op, const db_val_t *_v, const db_key_t *_c, const int _n, const int _nc, const db_key_t _o, db1_res_t **_r) { - return db_do_query(_h, _k, _op, _v, _c, _n, _nc, _o, _r, db_mysql_val2str, - db_mysql_submit_query, db_mysql_store_result); + return run_thread4P5I2P2((_thread_proto4P5I2P2)&db_mysql_query_impl, + (void *)_h, (void *)_k, (void *)_op, (void *)_v, (void *)_c, _n, + _nc, (void *)_o, (void *)_r); } /** _______________________________________________ Kamailio (SER) - Development Mailing List To unsubscribe send an email to sr-dev-le...@lists.kamailio.org
