#309: latest libssh2 library fails to authenticate with public key (RSA)

 libssh2 library was build against MinGW Makefiles and using OpenSSL.
 Target OS Windows 7.
 public/private key pair was generated using OpenSSL, without passphrase.
 I am using freeSSHd Server application, where I set a user "testuser" and
 authentication SSH public key only.

 My Code look like this:


 {{{


 // authenticate by public key.
 int iResult = libssh2_userauth_publickey_fromfile( mySession,
 "testuser", "public.pem", "private.pem", NULL );


 }}}


 '''iResult''' always returns '''LIBSSH2_ERROR_PUBLICKEY_UNVERIFIED'''.
 what am I doing wrong?
 I really can't help myself and I couldn't find out what I am doing wrong.

 By the way '''libssh2_userauth_password''' works fine, but I need public
 key authentication

 Could you please help me.

 Mohi

 I can confirm this leak. Happens with a Synology Server during

 libssh2_session_handshake)

 Hey, Thanks for the reply, I just checked for that and seeing something
 like below in libssh2.h file

 /* NOTE NOTE NOTE
  libssh2_trace() has no function in builds that aren't built with
 debug
  enabled
  */
 LIBSSH2_API int libssh2_trace(LIBSSH2_SESSION *session, int bitmask);

 I am not sure from where can I enable trace, Can you please guide me on
 that so I can make it enable and recompile lib.

 Thanks

 If you configured libssh2 using CMake, set ENABLE_DEBUG_LOGGING=ON.  For

 We will need to see the debug log to diagnose your problem.  You can get
 this by calling libssh2_trace(~0).  You may need to recompile libssh2 with

 For memcpy, having overlapping src and dest means undefined behaviour.

 In libssh2_session_method_pref() the memcpy in the while loop is obviously
 overlapping.

 Replace by memmove to fix.

 Found by OpenBSD strict memcpy.

Comment (by alamaison):

 I'm not sure how it's done via the PHP binding.  For libssh2 itself, you
 call libssh2_trace with a bitmask set to the kinds of debugging you are
 interested in.  To get everything, call libssh2_trace(~0).

 You may have to recompile libssh2 with debugging enabled:
 ENABLE_DEBUG_LOGGING=ON for CMake, --enable-debug=yes for Autotools.

Comment (by alamaison):

 That's the version of the PHP library that uses libssh2 under the bonnet.
 It looks like it's using libssh2 v1.4.2, which is no too bad.

 Unfortunately, we don't have enough information to go on.  Are you able to
 configure PHP's ssh2 to spit out the debug log from libssh2?

 And when you say the sessions logs are identical, which logs are
 identical to which?

Comment (by kotoroshinoto):

 giving the path to the libs with -L/not/usr/path/lib in LDFLAGS seems to
 sidestep the problem. I did however set the requisite paths in the various
 env variables, so it OUGHT to have been using that path anyway.

 That soname DOES exist (the one with .10) but it is NOT the correct one to
 be using, and it should certainly not be the one it finds first.

Comment (by danf):

 Applications are linked against the SONAME of the shared library, which
 looks to be libssl.so.10 in this case. If you have no file of that name,
 then there's no way for the run-time linker to find your library, so it
 continues along the search path and links against the one it *can*
 find—the system version.

Comment (by alamaison):

 The important thing with ExternalProject is that you can't just use it in
 your project's CMakeLists.txt because it doesn't fetch and build the
 subprojects until main project build time - too late for find_package,
 which runs at configure time, to pick them up. You have to make a wrapper
 project that uses ExternalProject to build the dependencies and also uses
 ExternalProject to build your project. This setup is called a CMake
 Superbuild or superproject.

 Hunter avoids the need for a superbuild but building the dependency
 projects at main project configure time.

 Thanks for the patch. I'll try and test it tonight

Comment (by danf):

 Your libssh2 library may have been linked to your special libssl at
 compile time, but it's not finding it at run-time. On Linux, you can use
 the LD_LIBRARY_PATH environment variable or /etc/ld.so.conf config file to
 point to the correct library location at run-time. Or, you can use the
 -rpath command-line option on the linker to hard-code that path into the
 library at compile time.

 the program appears to be linking against libcrypto.so.10 and remembering
 that it is using libcrypto.so.10 OR somehow loading that one at runtime
 instead of the one earlier on the path. (it seems to be specifically
 looking for the library with a .10 in its name)

 I'm trying to incorporate the new libssh2 cmake build into my own cmake
 build system with the add_subdirectory command. It mostly works except for
 a few places in src/CMakeLists.txt that use CMAKE_SOURCE_DIR. That
 variable points to the top-level project source dir. I'd recommend
 changing them to PROJECT_SOURCE_DIR or libssh2_SOURCE_DIR. When I make
 that change everything works fine for my use case.

Comment (by alamaison):

 Incorporating a project dependency by adding it as a subdirectory is a
 hack.  A commonly-used hack, admittedly, but still not a great idea.
 CMake provides better mechanisms such as ExternalProject with a
 superproject build.  Or you can use one of the package-managers available
 for CMake (I love [https://github.com/ruslo/hunter Hunter]).

 If you provide a patch that does what you're after, without making the
 CMake files more complex, I see no problem with applying it.  But I can't
 promise a future change won't break it.

 no matter what I do, it ends up linking to the system files:
 libssl.so.10 = /usr/lib64/libssl.so.10 (0x7f83a6248000)
 libcrypto.so.10 = /usr/lib64/libcrypto.so.10 (0x7f83a5e68000)

 it should be linking to the ones in
 ls /UCHC/HPC/Gooch/biotoolmodules/openssl/1.0.2a/lib/
 engines libcrypto.a libcrypto.so libcrypto.so.1.0.0 libssl.a libssl.so
 libssl.so.1.0.0 pkgconfig

 what do I need to tell the configure script to accomplish this?

 I'm picking up a memory leak in kex.c, line 205. 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.

 The fix looks good.  Could you add some comments to the patch so that, in
 a year's time, people aren't scratching their heads trying to work out why
 the gcrypt version uses NULL.

Comment:

 Agreed.  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=2217user=guestpass=guest
 that is fixed] (don't hold your breath), we can't safely call
 EVP_cleanup().

 If you want to avoid the memory leak (it's not really a leak - just looks
 like one to valgrind), call it yourself in your application.

Comment (by alamaison):

 Like #298, these are probably not real leaks.  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();
 }}}

 First: Thanks a lot for the new release.
 There is a memory leak with openssl: You call
 OpenSSL_add_all_algorithms() on init, but you don't free the memory on
 exit:
 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();

 Thanks a lot!

Comment (by ssbssa):

 The problem here is that gcry_mpi_scan() doesn't use the bignum provided
 by the argument, instead it creates a new one and overrides the one
 created by gcry_mpi_new() before.

 I've attached a possible solution.

Comment (by ios3):

 We have developed one iOS application to ssh using libssh2 library. There
 is all things working fine with libssh2 version 1.4.2, But I required to
 use 1.4.3 version to support arm64 bit architecture.

 I have update version and now using with 1.4.3 all things is working fine
 except key authentication. I have made one RSA key to ssh with my server,
 I have copied public key in authorized key file so that we can connect
 with that pc/server.

 Using this key when I try to connect/ssh it returns me error
 -18LIBSSH2_ERROR_AUTHENTICATION_FAILED. When I tried to ssh with same
 key and same server it allows me without any issue using version 1.4.2
 (older one). I don't what's happen.

 USing this method with para to check authenticate status
 libssh2_userauth_publickey_fromfile(session, username, pubkey,privatekey
 ,password);

 Below is detail how I m gettig para
 const char *pubkey= [_publicKey
 cStringUsingEncoding:NSUTF8StringEncoding];
 const char *privatekey= [_privateKey
 cStringUsingEncoding:NSUTF8StringEncoding];
 password=NULL
 const char* username = [username1
 cStringUsingEncoding:NSUTF8StringEncoding];
 const char* password = [passWd cStringUsingEncoding:NSUTF8StringEncoding];

 Please let me know if any thing wrong or missing here. FOr key I haven't
 use any password while generate it.

 Let me know if any more info require.

 Thanks.

 You need to provide more info. I use libssh2 on nothing but 64bit archs
 and I have not experienced any problems.

 Can you bisect your way to the offending commit that introduced the

Comment (by ios3):

 Hi..please give me some feedback about issue, Is there something wrong
 with library or am I missing something? As with older version it's working
 fine.

 It's working fine with older version of library to ssh with public key.
 But for same key If i tried to ssh it fails to authenticate and returns
 -18(LIBSSH2_ERROR_AUTHENTICATION_FAILED) in function
 libssh2_userauth_publickey_fromfile(session, username, publickey,
 privatekey, passphrase). What's wrong with new version of library?
 I am using it in iOS application. I am using version 1.4.3

 Affected are versions 1.4.3 and latest development version.

 Issue
 =

 Specifically crafted input from ssh server causes read access from
 unmapped memory region resulting in crash (Segmentation fault) and causing
 denial of service condition.

 Valgrind output:
 ==3670== Process terminating with default action of signal 11 (SIGSEGV)
 ==3670==  Access not within mapped region at address 0x6AA107D8
 ==3670==at 0x4087DB: _libssh2_ntohu32 (misc.c:163)
 ==3670==by 0x419E62: kex_agree_methods (kex.c:1583)

 ==3670==by 0x40CC04: libssh2_session_handshake (session.c:801)
 ==3670==by 0x402BCE: main (ssh2.c:118)

 The issue is caused by following code in kex.c:kex_agree_methods(...)
 function:

 /* Locate each string */
 kex_len = _libssh2_ntohu32(s);
 kex = s + 4;
 s += 4 + kex_len;
 hostkey_len = _libssh2_ntohu32(s);
 hostkey = s + 4;
 s += 4 + hostkey_len;
 crypt_cs_len = _libssh2_ntohu32(s);
 crypt_cs = s + 4;
 s += 4 + crypt_cs_len;
 crypt_sc_len = _libssh2_ntohu32(s);
 crypt_sc = s + 4;
 s += 4 + crypt_sc_len;
 mac_cs_len = _libssh2_ntohu32(s);
 mac_cs = s + 4;
 s += 4 + mac_cs_len;
 mac_sc_len = _libssh2_ntohu32(s);
 mac_sc = s + 4;
 s += 4 + mac_sc_len;
 comp_cs_len = _libssh2_ntohu32(s);
 comp_cs = s + 4;
 s += 4 + comp_cs_len;
 comp_sc_len = _libssh2_ntohu32(s);
 comp_sc = s + 4;

 It can be observed that various length fields (kex_len, hostkey_len,
 mac_cs_len, etc.) are taken from (untrusted) input and are used as offsets
 to memory location ('s' pointer) without any validation.

 Reproduction
 

 I'm attaching 'crash.input' file, an example of input that triggers this
 issue which could be reproduced with following steps:

 Run malicious 'ssh server':
 # cat crash.input | nc -l -p 22

 Run ssh2 from libssh2/example:
 $ ./ssh2 127.0.0.1

 Fix
 ===

 Proposed patch that fixes this issue is attached.

 The example direct_tcpip.c doesn't take care of EAGAIN case return by
 libssh2_channel_write. This can lead to non transmitted file when this
 error is raised, while this should just delay the transmission because the
 socket are busy.
 To see the error, just run a process with high priority on the receiver of
 data trasnmitted through the libssh2_channel_write.
 Solution is just to retry the call to libssh2_channel_write one (or
 several) other time.

 Here under is the current code taken from the git repo today:
 Git repo code:

 wr = 0;
 do {
   i = libssh2_channel_write(channel, buf, len);
   if (i  0) {
 fprintf(stderr, libssh2_channel_write: %d\n, i);
 goto shutdown;
   }
   wr += i;
 } while(i  0  wr  len);

 Code patched:
 wr = 0;
 do {
   i = libssh2_channel_write(channel, buf, len);
   if (i = 0)
   {
 wr += i;
   }
   else if(i == LIBSSH2_ERROR_EAGAIN)
   {
 fprintf(stderr, libssh2_channel_write: LIBSSH2_ERROR_EAGAIN, retry to
 write\n);
   }
   else {

Comment (by Eschaton):

 I've looked at this and it appears it would be pretty straightforward to
 do with only three additional callbacks modeled after the recv/send
 callbacks:

 - A get_blocking callback to get the current blocking state of the socket
 in the couple places it's checked
 - A set_blocking callback to set the current blocking state of the socket
 in the couple places it's adjusted
 - A poll callback to be used by _libssh2_wait_socket() and possibly the
 deprecated libssh2_poll()

 With only those three callbacks, it should be possible to layer libssh2
 atop an arbitrary transport rather than specifically atop Berkeley
 sockets.

 Apps on iOS can't run or communicate with their own daemons/agents, and

 Are you possibly using select() ? Then using file descriptors over 1024 is
 a common problem and source for pain and sorrow. Also, most *nix systems

 configure never detects EVP_aes_128_ctr even when it is present in
 openssl.  I have confirmed this in libssh2 1.4.3 using both openssl 1.0.1h
 and libressl 2.0.5.

 The issue seems to be the order in which libraries appear on the command
 line for the configure test.  I have a simple patch that resolves the
 issue and causes libssh2 to properly detect EVP_aes_128_ctr for both
 openssl and libressl.

 The solution is to use put the libs (-lcrypto -lssl) in the LIBS variable
 and not the LDFLAGS variable.  Patch attached.

 If an application happens to call the OpenSSL routine EVP_cleanup, then
 libssh2 will generate a segfault at the call to libssh2_sh1_update at line
 249 in kex.c. Of course, the application should not call EVP_cleanup
 prematurely, but to avoid crashes in your library, I suggest you guard
 against this possibility in a manner similar to your guard around the call
 to libssh2_md5_update at line 222 in kex.c.

 Only a subset of the functions used on a socket/fd passed into libssh2 are
 wrapped in standard callbacks. For example, libssh2 will still invoke the
 stock select/poll and ioctl functions on a socket it's passed, to do
 things like check for I/O and control non-blocking behavior.

 This makes it between difficult and impossible to use libssh2 (without
 significant modification) over another transport, or even over a socket
 where full control can't be given to the library (such as a socket managed
 via dispatch I/O on OS X or iOS).

 If all calls on the socket used by libssh2 always went through semantic
 callback wrappers (eg set non blocking, set reusable and so on, rather
 than do an ioctl) then it would be possible to use libssh2 with an
 entirely-application-layer transport. It might also make it easier to
 abstract

 OpenBSD 5.5 is changing the default MACs available to sshd. Libssh2
 supplies the following

 hmac-sha1,hmac-sha1-96,hmac-md5,hmac-md5-96,hmac-ripemd160,hmac-
 ripemd...@openssh.com

 while OpenBSD 5.5 expects

 umac-64-...@openssh.com,umac-128-...@openssh.com,hmac-

 sha2-512-...@openssh.com,umac...@openssh.com,umac-...@openssh.com,hmac-

 It appears libssh2's MAC support needs to be updated.

 Hi,

 I used the libssh2 examples sftp.c and sftpdir.c, lightly modified to
 get more information on the errors.

 I have to get files from several subdirectories on a SFTP Server.
 Some of these subdirectories ar written by other users, one is written by
 the user which I use as login with user and password.
 All users are in the same group.

 Getting files which are created by my user works fine.

 But when I try to get the other files then libssh2_sftp_open fails,
 libssh2_session_last_error returns -31 (= LIBSSH2_ERROR_SFTP_PROTOCOL) and
 libssh2_sftp_last_error returns 3 (= LIBSSH2_FX_PERMISSION_DENIED).

 I have no problems reading the directories (libssh2_sftp_opendir /
 libssh2_sftp_readdir_ex).


 Examples:
 My directory on the server:
 -rw-rw-r--1 My_UserGroup1   7923 Apr  9 13:49 file1   (ok)

 Another directory:
 -rw-r--r--1 Other_User Group1   1229 Apr  9 00:59 file2   (fails)


 The system I work on is SUSE Linux Enterprise Server 11 (i586).
 The version of libssh2 is 1.4.3.

 /usr/bin/sftp  has no problems, I can get all files; same on windows with
 WinSCP.
 The problem must be on my side.

 What could I make better? Are there more steps to do than coded in the
 examples?

 Thanks

 Peter

 The libssh2 library is required by this module.  If you don't have it, you
 can
 download it from http://www.libssh2.org; you may also need OpenSSL, which
 can
 be obtained from http://www.openssl.org , or libgcrypt, which can be
 obtained
 from http://www.gnupg.org .

 Debian:   sudo aptitude install libssh2-1-dev
 OpenSUSE: sudo zypper in libssh2-1 libssh2-devel

 You can pass your libssh2 lib and include dirs (and extra link args) on
 the
 command line. E.g.:

 perl Makefile.PL lib=$HOME/libssh2/lib inc=$HOME/libssh2/include \
 ldargs=-lz

 These can also be set through the
 LIBSSH2_LIB/LIBSSH2_INCLUDE/LIBSSH2_LDARGS
 environment variables.

 To build with libgcrypt instead of OpenSSL, pass 'gcrypt' as a parameter
 to
 Makefile.PL, e.g.:

 perl Makefile.PL gcrypt

 If you want to build on Windows, see the file BUILDING.WIN32 in the
 distribution.

 Can't link/include C library 'libssh2.h', 'ssh2', aborting.
 No 'Makefile' createdCPAN: YAML loaded ok (v0.84)
   RKITOVER/Net-SSH2-0.53.tar.gz

   Make had some problems, won't test
 Failed during this command:
  RKITOVER/Net-SSH2-0.53.tar.gz: writemakefile NO -- No

 So Im wondering if / how I can check that libssh2 is actually loaded
 correctly and how do I get perl to see the install.

 Thanks !!! Popeye

 I think I found a bug in direct_tcpip.c

 This is the problematic section. It tries to send len bytes stored in
 buf on a channel.

 {{{
 235 wr = 0;
 236 do {
 237 i = libssh2_channel_write(channel, buf, len);
 238 if (i  0) {
 239 fprintf(stderr, libssh2_channel_write: %d\n,
 i);
 240 goto shutdown;
 241 }
 242 wr += i;
 243 } while(i  0  wr  len);
 }}}

 However, when libssh2_channel_write fails to write everything at once,
 then this code will try writing the data in buf again from the beginning!
 Also, I don't know why it aborts when i=0, this would just ignore some of
 the data.

 I think this code should rather like this:

 {{{
 235 wr = 0;
 236 while (wrlen) {
 237 i = libssh2_channel_write(channel, buf+wr, len);
 238 if (i  0) {
 239 fprintf(stderr, libssh2_channel_write: %d\n,
 i);
 240 goto shutdown;
 241 }
 242 wr += i;
 243 }
 }}}

 Please excuse that I include the code inline in this ticket, I am not very
 familiar with git, but I wanted to report this issue nevertheless.

#282: SCP may read the wrong file if several channels are opened in parallel

 Attached is a modification of the {{{scp_nonblock.c}}} example that can
 reproduce this problem. The modifications are the following:
 * Removed Windows specific code for simplicity (tested on SUSE Linux 11).
 * Multiple files can be specified on the command line (arguments after
 password).
 * Multiple files are read in parallel.
 * Each file is written to a file of the same name on the local machine.

 The problem may not always come up. I tested with 10 files of a size about
 2 MB. The problem seems to occur when establishing the channels are
 finished in a different order as they are started.

 The example works as the following.
 * The information for each channel is stored in the {{{descriptor}}}
 structure:
 {{{
 struct descriptor {
 char* filename;
 struct stat fileinfo;
 LIBSSH2_CHANNEL *channel;
 int outfd;
 off_t got;
 };
 }}}
 * Open the session and authenticate (no change of the algorithm until this
 point).
 * Enter a main loop with the exit condition specified later (when all
 files are read).
 {{{
 while(1) {
 int activeChannels = 0;
 }}}
 * Now enter an inner loop that iterates through all descriptors. Inside
 this loop we do everything we can without waiting for the socket.
 {{{
 for (i = 0; i  descriptorNum; ++i) {
 struct descriptor* desc = descriptors[i];
 int rc;
 }}}
 * If the channel is not yet established, then try to create it.
 {{{
 if (!desc-channel) {
 desc-channel = libssh2_scp_recv(session, desc-filename,
 desc-fileinfo);
 ...
 ++activeChannels;
 }}}
 * If the channel is already established, then read from it.
 {{{
 } else {
 char mem[1024*24];
 fprintf(stderr, Reading from %s...\n, desc-filename);
 do {
 ...
 rc = libssh2_channel_read(desc-channel, mem, amount);
 ...
 } while (rc  0);
 ...
 if (desc-got  desc-fileinfo.st_size) {
 ++activeChannels;
 }
 }
 }}}
 * After the inner loop, check whether we need to continue. If not, finish
 the main loop.
 {{{
 if (activeChannels  0) {
 waitsocket(sock, session); /* now we wait */
 continue;
 }
 }
 }}}

Comment (by danf):

 It would be much more useful to attach a log where you attempted to use
 OpenSSL, rather than one with --without-libgcrypt --without-openssl  Does
 the file /usr/local/ssl/include/openssl/ssh.h exist?

 I'm running on Suse Linux Enterprise Server 11 SP 1 (64bit).

 I could'nt install libssh2-1.4.3.

 I have attached the config.log for your reference. The errors seem to say
 that it couldn't locate openssl/ssl.h when i did a ./configure. I tried
 with the below command:

 ./configure --without-libgcypt --with-openssl --with-openssl-
 prefix=/usr/local/ssl

 but it doesn't help.

 The OpenSSL was downloaded from www.openssl.org and OpenSSL 1.0.1e
 version was compiled and installed in /usr/local/ssl directory.

 Please help! thank you!

 PS: i couldn't attach files for this ticket. I copied and pasted below.
 Thank you!

 This file contains any messages produced by compilers while
 running configure, to aid debugging if configure makes a mistake.

 It was created by libssh2 configure -, which was
 generated by GNU Autoconf 2.69.  Invocation command line was

   $ ./configure --without-libgcrypt --without-openssl

 openssl: initialise the digest context before calling EVP_DigestInit()

 When using the OpenSSL libraries in FIPS mode, the function call
 EVP_DigestInit() is actually #defined to FIPS_digestinit().
 Unfortunately wheres EVP_DigestInit() initialises the context and then
 calls EVP_DigestInit_ex(), this function assumes that the context has
 been pre-initialised and crashes when it isn't.

 knownhosts: handle unknown key types

 Store but don't use keys of unsupported types on the known_hosts file.

 Currently, when libssh2 parses a known_host file containing keys of some
 type it doesn't natively support, it stops reading the file and returns
 an error.

 That means, that the known_host file can not be safely shared with other
 software supporting other key types (i.e. OpenSSH).

 This patch adds support for handling keys of unknown type. It can read
 and write them, even if they are never going to be matched.

 At the source level the patch does the following things:

 - add a new unknown key type LIBSSH2_KNOWNHOST_KEY_UNKNOWN

 - add a new slot (key_type_name) on the known_host struct that is
 used to store the key type in ascii form when it is not supported

 - parse correctly known_hosts entries with unknown key types and
 populate the key_type_name slot

 - print correctly known_hosts entries of unknown type

 - when checking a host key ignore keys that do not match the key

 In a multithreaded application, libssh2_init() ought to call
 gcry_check_version(), or the documentation for libssh2 ought to advise
 that libgcrpyt's gcry_check_version() must be called, before
 libssh2_init() is executed.

 Please see here: http://www.gnupg.org/documentation/manuals/gcrypt-devel
 /Initializing-the-library.html

 Without this call, we get SIGABRTs from gcrpyt.

 In summary, in a multithread application, the sequence of calls should be:

 {{{#!c
  // Enable thread safety for gcrypt.
  int result = gcry_control(GCRYCTL_SET_THREAD_CBS, gcry_threads_pthread);
  if (!gcry_check_version (GCRYPT_VERSION))
  {

Comment (by maxmtl):

 I am not sure if it applies to your case, but I found out that the socket
 used by libssh2 must be set non-blocking, even if the libssh2 API is used
 blocking. I did not find this in the API reference or in the examples.
 (submitting a patch for this is on my list of things to do). Is your
 socket set to non-blocking?

[libssh2] #276: do not fail when keys of unknown type are read from known_hosts file

#276: do not fail when keys of unknown type are read from known_hosts file

 Currently, when `libssh2_knownhost_readfile` finds a key of a type not
 natively supported by the library, it stops reading and returns an error.

 This is very annoying as OpenSSH uses other key types and so its
 known_host can not be used. Even worse, if the programmer is sloppy, and
 doesn't check for errors when calling `libssh2_knownhost_readfile` and
 later saves the file, it will wipe out any entries after the unsupported
 one.

 The attached patch solves that issue.

 Commit log follows:

 {{{
 store but don't use keys of unsupported types on the known_hosts
 file.

 Currently, when libssh2 parses a known_host file containing keys
 of some type it doesn't natively support, it stops reading the
  file and returns an error.

 That means, that the known_host file can not be safely shared
 with other software supporting other key types (i.e. OpenSSH).

 This patch adds support for handling keys of unknown type. It can
 read and write them, even if they are never going to be matched.

 At the source level the patch does the following things:

 - add a new unknown key type LIBSSH2_KNOWNHOST_KEY_UNKNOWN

 - add a new slot (key_type_name) on the known_host struct that is
 used to store the key type in ascii form when it is not supported

 - parse correctly known_hosts entries with unknown key types and
 populate the key_type_name slot

 - print correctly known_hosts entries of unknown type

 - when checking a host key ignore keys that do not match the key
 type

 besides accessing a session for the alloc/free callbacks, only the actual
 userauth method needs a session. I propose an userauth_ex method that
 takes a session as an argument, so that a single agent connection can be
 shared if you're making many connections (think a dsh or parallel-scp
 replacement).

 for now I've worked around this by jsut overwriting the session field in
 LIBSSH2_AGENT before calling userauth, and it's working great.

 Hi,

 Can any one help me in understanding what exactly the
 libssh2_session_set_timeout API call will do. As per the libssh2 docs , I
 read it as used to set timeout for blocking functions. But I could able to
 understand whether this will set timeout for only the API above which this
 libssh2_session_set_timeout  is set or it will set timeout on entire
 session and thus this timeout will be effected to all the API's used with
 that session.

 I am new to libssh2. So please help me in understanding the usage.

 It would be more helpful, if I can get a sample program to use this
 libssh2_session_set_timeout((LIBSSH2_SESSION *session, long timeout); API.

 Thanking you in advance.

 We've done numerous bug fixes after the 1.2.9 release so it makes sense if
 you first try out version 1.4.3 and if the problem remains post us a
 little code snippet we can use to repeat the problem.

 We are using libssh2 protocol to initiate SFTP transfer while sending
 files to remote server.
 In stability tests where traffic is flowing we observed that one file got
 stuck in sending.

 At this point, we have collected the gstack and observed that the hang is
 there in libssh2_sftp_stat_ex API as shown below

 Thread 5 (Thread 0x7f5c6bff7700 (LWP 29770)):
 #0  0x7f5c7a2c0786 in poll () from /lib64/libc.so.6
 #1  0x7f5c7abf81f7 in ?? () from /usr/lib64/libssh2.so.1
 #2  0x7f5c7abfb9b2 in libssh2_sftp_stat_ex () from
 /usr/lib64/libssh2.so.1
 #3  0x004f4fc9 in SftpAdapterClass::sendFile1(void*, std::string,
 std::string, bool) ()

 The libssh2 library we are using here is libssh2-1-1.2.9-4.2.2.1.

 Please help me in analyzing what could be the reason for
 libssh2_sftp_stat_ex  to get hang.

 In the Feature update for libssh2 for this libssh2-1-1.2.9-4.2.2.1
 release , it is written

 In addition to that some problems were fixed, including a
  possible application hang when waiting for a remote server
  to return the results of a command.

 So we feel that hangs occurred while using some of the libssh2 API's are
 addressed in this release.

 So can you let us know whether the hang in libssh2_sftp_stat_ex  is
 addressed in libssh2-1-1.2.9-4.2.2.1 release.
 Or is there any other later release which has fixed up the hangs that are
 occurring in libssh2 API calls.

 Thanking you in Advance.
