First, thanks a lot for the new release. Maybe there are some
memory leaks:

a) #298: Clean openssl-tables via "EVP_cleanup()":
 https://www.openssl.org/docs/crypto/OpenSSL_add_all_algorithms.html

 Replace:

 #define libssh2_crypto_init() OpenSSL_add_all_algorithms()
 #define libssh2_crypto_exit()

 With:

 #define libssh2_crypto_init() OpenSSL_add_all_algorithms()
#define libssh2_crypto_exit() EVP_cleanup();

b) #299: _libssh2_rsa_new() in openssl.c:69 is not free'd()
I have attached the valgrind-output.

Thanks a lot

OpenSSL doesn't count calls to OpenSSL_add_all_algorithms() and matching calls to EVP_cleanup(). Until [http://rt.openssl.org/Ticket/Display.html?id=2217&user=guest&pass=guest that is fixed] (don't hold your breath), we can't safely call EVP_cleanup().

OpenSSL caches various pieces of global data that it initialises on demand. Once loaded, it caches them for the lifetime of the program. Some even _have_ to be kept for security reasons. If they are causing a problem by creating false positives when you're checking for memory leaks, try calling some of the globally-destructive OpenSSL cleanup functions in your application, only when running your leak checker or test suite. The following works for me: {{{ ::RAND_cleanup(); ::ENGINE_cleanup(); ::CONF_modules_unload(1); ::CONF_modules_free(); ::EVP_cleanup(); ::ERR_free_strings(); ::ERR_remove_state(0); ::CRYPTO_cleanup_all_ex_data(); }}} -- Ticket URL: libssh2 C library for writing portable SSH2 clients _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel From libssh2-devel-bounces@cool.haxx.se Fri Apr 3 02:39:07 2015 Return-Path: Received: from www.haxx.se (localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.4/8.14.4/Debian-7) with ESMTP id t330chMn016948; Fri, 3 Apr 2015 02:39:04 +0200 Received: from earth.stuge.se (earth.stuge.se [212.116.89.126]) by giant.haxx.se (8.14.4/8.14.4/Debian-7) with ESMTP id t330ceNg016930 (version=TLSv1/SSLv3 cipher=ECDHE-RSA-AES256-GCM-SHA384 bits=256 verify=NOT) for ; Fri, 3 Apr 2015 02:38:40 +0200 Received: (qmail 12680 invoked from network); 3 Apr 2015 00:42:18 -0000 Received: from unknown (HELO earth.stuge.se) (127.0.0.1) by localhost with SMTP; 3 Apr 2015 00:42:18 -0000 MIME-Version: 1.0 From: "libssh2 Trac" X-Trac-Version: 1.0dev Precedence: bulk Auto-Submitted: auto-generated X-Mailer: Trac 1.0dev, by Edgewall Software To: jcollins@tsco.ca, daniel@haxx.se, ssbssa@yahoo.de, awl03@doc.ic.ac.uk X-Trac-Project: libssh2 Date: Fri, 03 Apr 2015 00:42:18 -0000 X-URL: https://trac.libssh2.org/ Subject: Re: [libssh2] #168: Memory leak in libssh2_session_startup X-Trac-Ticket-URL: https://trac.libssh2.org/ticket/168#comment:3 Message-ID: <060.3c67184e4cdb7d3813a6de34252cc071@libssh2.stuge.se> References: <045.4ab89fbe3b9a399ba8e6168544d544ac@libssh2.stuge.se> X-Trac-Ticket-ID: 168 In-Reply-To: <045.4ab89fbe3b9a399ba8e6168544d544ac@libssh2.stuge.se> X-MIME-Autoconverted: from base64 to 8bit by giant.haxx.se id t330ceNg016930 Cc: libssh2-devel@cool.haxx.se X-BeenThere: libssh2-devel@cool.haxx.se X-Mailman-Version: 2.1.18 List-Id: libssh2 development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Reply-To: trac@libssh2.stuge.se, libssh2 development Content-Type: text/plain; charset="utf-8" Errors-To: libssh2-devel-bounces@cool.haxx.se Sender: "libssh2-devel" Content-Transfer-Encoding: 8bit X-MIME-Autoconverted: from base64 to 8bit by giant.haxx.se id t330chMn016948 #168: Memory leak in libssh2_session_startup -----------------------+------------------- Reporter: jcollins | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: API | Version: 1.2.4 Resolution: | Keywords: Blocked By: | Blocks: -----------------------+------------------- Comment (by alamaison): The fix looks good.

The code is: {{{ session->server_hostkey = LIBSSH2_ALLOC(session, session->server_hostkey_len); }}} For some execution paths, session->server_hostkey is already allocated, so when the contents of the pointer are replaced, there's a leak. Oddly, I found it while SSHing into a Synology device, and it's fully repeatable. What's strange is that I don't get the leak when connecting to a "proper" Linux install such as Debian 7. For now, my workaround is to add {{{ if (session->server_hostkey) { LIBSSH2_FREE(session, session->server_hostkey); } }}} just above the leaking call, but that doesn't seem like the most reliable solution to me, since it seems like the code is reusing a session which hasn't been cleared properly, and there's probably more cleanup that should be done against the session. -- Ticket URL: libssh2 C library for writing portable SSH2 clients _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel From libssh2-devel-bounces@cool.haxx.se Fri Apr 3 14:09:20 2015 Return-Path: Received: from www.haxx.se (localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.4/8.14.4/Debian-7) with ESMTP id t33C9IjY012401; Fri, 3 Apr 2015 14:09:19 +0200 Received: from earth.stuge.se (earth.stuge.se [212.116.89.126]) by giant.haxx.se (8.14.4/8.14.4/Debian-7) with ESMTP id t33C9EOh012381 (version=TLSv1/SSLv3 cipher=ECDHE-RSA-AES256-GCM-SHA384 bits=256 verify=NOT) for ; Fri, 3 Apr 2015 14:09:14 +0200 Received: (qmail 1337 invoked from network); 3 Apr 2015 12:12:52 -0000 Received: from unknown (HELO earth.stuge.se) (127.0.0.1) by localhost with SMTP; 3 Apr 2015 12:12:52 -0000 MIME-Version: 1.0 From: "libssh2 Trac" X-Trac-Version: 1.0dev Precedence: bulk Auto-Submitted: auto-generated X-Mailer: Trac 1.0dev, by Edgewall Software To: jcollins@tsco.ca, daniel@haxx.se, ssbssa@yahoo.de, awl03@doc.ic.ac.uk X-Trac-Project: libssh2 Date: Fri, 03 Apr 2015 12:12:52 -0000 X-URL: https://trac.libssh2.org/ Subject: Re: [libssh2] #168: Memory leak in libssh2_session_startup X-Trac-Ticket-URL: https://trac.libssh2.org/ticket/168#comment:4 Message-ID: <060.e27169d0528ad33b4baffa4121430f78@libssh2.stuge.se> References: <045.4ab89fbe3b9a399ba8e6168544d544ac@libssh2.stuge.se> X-Trac-Ticket-ID: 168 In-Reply-To: <045.4ab89fbe3b9a399ba8e6168544d544ac@libssh2.stuge.se> X-MIME-Autoconverted: from base64 to 8bit by giant.haxx.se id t33C9EOh012381 Cc: libssh2-devel@cool.haxx.se X-BeenThere: libssh2-devel@cool.haxx.se X-Mailman-Version: 2.1.18 List-Id: libssh2 development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Reply-To: trac@libssh2.stuge.se, libssh2 development Content-Type: text/plain; charset="utf-8" Errors-To: libssh2-devel-bounces@cool.haxx.se Sender: "libssh2-devel" Content-Transfer-Encoding: 8bit X-MIME-Autoconverted: from base64 to 8bit by giant.haxx.se id t33C9IjY012401 #168: Memory leak in libssh2_session_startup -----------------------+------------------- Reporter: jcollins | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: API | Version: 1.2.4 Resolution: | Keywords: Blocked By: | Blocks: -----------------------+------------------- Comment (by ssbssa): Like this, or did you mean more?
