From 54ed71dba174385ab0d8fa415e09262f6250430c Mon Sep 17 00:00:00 2001 From: l17zhou Date: Mon, 4 Nov 2019 08:45:52 +0200 Subject: rpc: Cleanup SSL specific data at the time of freeing rpc object Problem: At the time of cleanup rpc object ssl specific data is not freeing so it has become a leak. Solution: To avoid the leak cleanup ssl specific data at the time of cleanup rpc object Credits: l17zhou Fixes: bz#1768407 Change-Id: I37f598673ae2d7a33c75f39eb8843ccc6dffaaf0 --- rpc/rpc-transport/socket/src/socket.c | 22 ++++++++++++++++++++-- 1 file changed, 20 insertions(+), 2 deletions(-) (limited to 'rpc') diff --git a/rpc/rpc-transport/socket/src/socket.c b/rpc/rpc-transport/socket/src/socket.c index 26903df44d6..395ae43dd15 100644 --- a/rpc/rpc-transport/socket/src/socket.c +++ b/rpc/rpc-transport/socket/src/socket.c @@ -439,6 +439,7 @@ ssl_setup_connection_postfix(rpc_transport_t *this) gf_log(this->name, GF_LOG_DEBUG, "SSL verification succeeded (client: %s) (server: %s)", this->peerinfo.identifier, this->myinfo.identifier); + X509_free(peer); return gf_strdup(peer_CN); /* Error paths. */ @@ -1180,7 +1181,15 @@ __socket_reset(rpc_transport_t *this) memset(&priv->incoming, 0, sizeof(priv->incoming)); gf_event_unregister_close(this->ctx->event_pool, priv->sock, priv->idx); - + if (priv->use_ssl && priv->ssl_ssl) { + SSL_clear(priv->ssl_ssl); + SSL_free(priv->ssl_ssl); + priv->ssl_ssl = NULL; + } + if (priv->use_ssl && priv->ssl_ctx) { + SSL_CTX_free(priv->ssl_ctx); + priv->ssl_ctx = NULL; + } priv->sock = -1; priv->idx = -1; priv->connected = -1; @@ -3250,7 +3259,6 @@ socket_server_event_handler(int fd, int idx, int gen, void *data, int poll_in, new_priv->sock = new_sock; new_priv->ssl_enabled = priv->ssl_enabled; - new_priv->ssl_ctx = priv->ssl_ctx; new_priv->connected = 1; new_priv->is_server = _gf_true; @@ -4699,6 +4707,16 @@ fini(rpc_transport_t *this) pthread_mutex_destroy(&priv->out_lock); pthread_mutex_destroy(&priv->cond_lock); pthread_cond_destroy(&priv->cond); + if (priv->use_ssl && priv->ssl_ssl) { + SSL_clear(priv->ssl_ssl); + SSL_free(priv->ssl_ssl); + priv->ssl_ssl = NULL; + } + if (priv->use_ssl && priv->ssl_ctx) { + SSL_CTX_free(priv->ssl_ctx); + priv->ssl_ctx = NULL; + } + if (priv->ssl_private_key) { GF_FREE(priv->ssl_private_key); } -- cgit
