security: fix for vulnerability CVE-2014-0017

When accepting a new connection, a forking server based on libssh forks
and the child process handles the request. The RAND_bytes() function of
openssl doesn't reset its state after the fork, but simply adds the
current process id (getpid) to the PRNG state, which is not guaranteed
to be unique.
This can cause several children to end up with same PRNG state which is
a security issue.

-4* Contributing
+4* API Changes !
 -_-_-_-_-_-_-_-_-_
 
-Please read the file 'SubmittingPatches' next to this README file. It explains
-our copyright policy and how you should send patches for upstream inclusion.
+Changes between 0.4 and 0.5
+---------------------------
+
+We use the ssh_ prefix as namespace for every function now. There is a legacy.h
+which could be used to get the old function names.
+
+Changes between 0.3 and 0.4
+---------------------------
+
+We changed libssh to be typesafe now:
+
+SSH_SESSION *session -> ssh_session session
+SFTP_SESSION *sftp -> sftp_session sftp
+CHANNEL *channel -> ssh_channel channel
+STRING *string -> ssh_string string
+...
+
+The options structure has been removed and there is a new function. This
+function can set all available options now. You can find the enum in the
+header file and it is documented. Example:
+
+ssh_options_set(session, SSH_OPTIONS_HOST, "localhost");
+
+5* Copyright policy
+-_-_-_-_-_-_-_-_-_-_
+
+libssh is a project with distributed copyright ownership, which means we prefer
+the copyright on parts of libssh to be held by individuals rather than
+corporations if possible. There are historical legal reasons for this, but one
+of the best ways to explain it is that it’s much easier to work with
+individuals who have ownership than corporate legal departments if we ever need
+to make reasonable compromises with people using and working with libssh.
+
+We track the ownership of every part of libssh via git, our source code control
+system, so we know the provenance of every piece of code that is committed to
+libssh.
+
+So if possible, if you’re doing libssh changes on behalf of a company who
+normally owns all the work you do please get them to assign personal copyright
+ownership of your changes to you as an individual, that makes things very easy
+for us to work with and avoids bringing corporate legal departments into the
+picture.
+
+If you can’t do this we can still accept patches from you owned by your
+employer under a standard employment contract with corporate copyright
+ownership. It just requires a simple set-up process first.
+
+We use a process very similar to the way things are done in the Linux Kernel
+community, so it should be very easy to get a sign off from your corporate
+legal department. The only changes we’ve made are to accommodate the license we
+use, which is LGPLv2 (or later) whereas the Linux kernel uses GPLv2.
+
+The process is called signing.
+
+How to sign your work
+----------------------
+
+Once you have permission to contribute to libssh from your employer, simply
+email a copy of the following text from your corporate email address to:

-Coding conventions in the libssh tree
-======================================
-
-===========
-Quick Start
-===========
-
-Coding style guidelines are about reducing the number of unnecessary
-reformatting patches and making things easier for developers to work together.
-
-You don't have to like them or even agree with them, but once put in place we
-all have to abide by them (or vote to change them).  However, coding style
-should never outweigh coding itself and so the guidelines described here are
-hopefully easy enough to follow as they are very common and supported by tools
-and editors.
-
-The basic style for C code, is the Linux kernel coding style (See
-Documentation/CodingStyle in the kernel source tree). This closely matches what
-libssh developers use already anyways, with a few exceptions as mentioned
-below.
-
-But to save you the trouble of reading the Linux kernel style guide, here
-are the highlights.
-
-* Maximum Line Width is 80 Characters
-  The reason is not about people with low-res screens but rather sticking
-  to 80 columns prevents you from easily nesting more than one level of
-  if statements or other code blocks.
-
-* Use 4 Spaces to Indent
-
-* No Trailing Whitespace
-  Clean up your files before committing.
-
-* Follow the K&R guidelines.  We won't go through all of them here. Do you
-  have a copy of "The C Programming Language" anyways right?
-
-
-=============
-Editor Hints
-=============
-
-Emacs
-------
-Add the follow to your $HOME/.emacs file:
-
-  (add-hook 'c-mode-hook
-    (lambda ()
-        (c-set-style "linux")
-        (c-toggle-auto-state)))
-
-
-Vim
-----
-
-For the basic vi editor included with all variants of \*nix, add the
-following to $HOME/.vimrc:
-
-    set ts=4 sw=4 et cindent
-
-You can use the Vim gitmodline plugin to store this in the git config:
-
-    http://git.cryptomilk.org/projects/vim-gitmodeline.git/
-
-For Vim, the following settings in $HOME/.vimrc will also deal with
-displaying trailing whitespace:
-
-    if has("syntax") && (&t_Co > 2 || has("gui_running"))
-        syntax on
-        function! ActivateInvisibleCharIndicator()
-            syntax match TrailingSpace "[ \t]\+$" display containedin=ALL
-            highlight TrailingSpace ctermbg=Red
-        endf
-        autocmd BufNewFile,BufRead * call ActivateInvisibleCharIndicator()
-    endif
-    " Show tabs, trailing whitespace, and continued lines visually
-    set list listchars=tab:»·,trail:·,extends:…
-
-    " highlight overly long lines same as TODOs.
-    set textwidth=80
-    autocmd BufNewFile,BufRead *.c,*.h exec 'match Todo /\%>' . &textwidth . 'v.\+/'
-
-
-==========================
-FAQ & Statement Reference
-==========================
-
-Comments
----------
-
-Comments should always use the standard C syntax.  C++ style comments are not
-currently allowed.
-
-The lines before a comment should be empty. If the comment directly belongs to
-the following code, there should be no empty line after the comment, except if
-the comment contains a summary of multiple following code blocks.
-
-This is good:
-
-    ...
-    int i;
-
-    /*
-     * This is a multi line comment,
-     * which explains the logical steps we have to do:
-     *
-     * 1. We need to set i=5, because...
-     * 2. We need to call complex_fn1
-     */
-
-    /* This is a one line comment about i = 5. */
-    i = 5;
-
-    /*
-     * This is a multi line comment,
-     * explaining the call to complex_fn1()
-     */
-    ret = complex_fn1();
-    if (ret != 0) {
-    ...
-
-    /**
-     * @brief This is a doxygen comment.
-     *
-     * This is a more detailed explanation of
-     * this simple function.
-     *
-     * @param[in]   param1     The parameter value of the function.
-     *
-     * @param[out]  result1    The result value of the function.
-     *
-     * @return              0 on success and -1 on error.
-     */
-    int example(int param1, int *result1);
-
-This is bad:
-
-    ...
-    int i;
-    /*
-     * This is a multi line comment,
-     * which explains the logical steps we have to do:
-     *
-     * 1. We need to set i=5, because...
-     * 2. We need to call complex_fn1
-     */
-    /* This is a one line comment about i = 5. */
-    i = 5;
-    /*
-     * This is a multi line comment,
-     * explaining the call to complex_fn1()
-     */
-    ret = complex_fn1();
-    if (ret != 0) {
-    ...
-
-    /*This is a one line comment.*/
-
-    /* This is a multi line comment,
-       with some more words...*/
-
-    /*
-     * This is a multi line comment,
-     * with some more words...*/
-
-Indention & Whitespace & 80 columns
-------------------------------------
-
-To avoid confusion, indentations have to be 4 spaces. Do not use tabs!.  When
-wrapping parameters for function calls, align the parameter list with the first
-parameter on the previous line.  For example,
-
-    var1 = foo(arg1,
-               arg2,
-               arg3);
-
-The previous example is intended to illustrate alignment of function
-parameters across lines and not as encourage for gratuitous line
-splitting.  Never split a line before columns 70 - 79 unless you
-have a really good reason.  Be smart about formatting.
-
-
-If, switch, & Code blocks
---------------------------
-
-Always follow an 'if' keyword with a space but don't include additional
-spaces following or preceding the parentheses in the conditional.
-This is good:
-
-    if (x == 1)
-
-This is bad:
-
-    if ( x == 1 )
-
-or
-
-    if (x==1)
-
-Yes we have a lot of code that uses the second and third form and we are trying
-to clean it up without being overly intrusive.
-
-Note that this is a rule about parentheses following keywords and not
-functions.  Don't insert a space between the name and left parentheses when
-invoking functions.
-
-Braces for code blocks used by for, if, switch, while, do..while, etc.  should
-begin on the same line as the statement keyword and end on a line of their own.
-You should always include braces, even if the block only contains one
-statement.  NOTE: Functions are different and the beginning left brace should
-be located in the first column on the next line.
-
-If the beginning statement has to be broken across lines due to length, the
-beginning brace should be on a line of its own.
-
-The exception to the ending rule is when the closing brace is followed by
-another language keyword such as else or the closing while in a do..while loop.
-
-Good examples:
-
-    if (x == 1) {
-        printf("good\n");
-    }
-
-    for (x = 1; x < 10; x++) {
-        print("%d\n", x);
-    }
-
-    for (really_really_really_really_long_var_name = 0;
-         really_really_really_really_long_var_name < 10;
-         really_really_really_really_long_var_name++)
-    {
-        print("%d\n", really_really_really_really_long_var_name);
-    }
-
-    do {
-        printf("also good\n");
-    } while (1);
-
-Bad examples:
-
-    while (1)
-    {
-        print("I'm in a loop!\n"); }
-
-    for (x=1;
-         x<10;
-         x++)
-    {
-        print("no good\n");
-    }
-
-    if (i < 10)
-        print("I should be in braces.\n");
-
-
-Goto
------
-
-While many people have been academically taught that "goto"s are fundamentally
-evil, they can greatly enhance readability and reduce memory leaks when used as
-the single exit point from a function. But in no libssh world what so ever is a
-goto outside of a function or block of code a good idea.
-
-Good Examples:
-
-    int function foo(int y)
-    {
-        int *z = NULL;
-        int rc = 0;
-
-        if (y < 10) {
-            z = malloc(sizeof(int)*y);
-            if (z == NULL) {
-                rc = 1;
-                goto done;
-            }
-        }
-
-        print("Allocated %d elements.\n", y);
-
-    done:
-        if (z != NULL) {
-            free(z);
-        }
-
-        return rc;
-    }
-
-Initialize pointers
--------------------
-
-All pointer variables MUST be initialized to NULL. History has
-demonstrated that uninitialized pointer variables have lead to various
-bugs and security issues.
-
-Pointers MUST be initialized even if the assignment directly follows
-the declaration, like pointer2 in the example below, because the
-instructions sequence may change over time.
-
-Good Example:
-
-    char *pointer1 = NULL;
-    char *pointer2 = NULL;
-
-    pointer2 = some_func2();
-
-    ...
-
-    pointer1 = some_func1();
-
-Typedefs
----------
-
-libssh tries to avoid "typedef struct { .. } x_t;" so we do always try to use
-"struct x { .. };". We know there are still such typedefs in the code, but for
-new code, please don't do that anymore.
-
-Make use of helper variables
------------------------------
-
-Please try to avoid passing function calls as function parameters in new code.
-This makes the code much easier to read and it's also easier to use the "step"
-command within gdb.
-
-Good Example:
-
-    char *name;
-
-    name = get_some_name();
-    if (name == NULL) {
-        ...
-    }
-
-    rc = some_function_my_name(name);
-    ...
-
-
-Bad Example:
-
-    rc = some_function_my_name(get_some_name());
-    ...
-
-Please try to avoid passing function return values to if- or while-conditions.
-The reason for this is better handling of code under a debugger.
-
-Good example:
-
-    x = malloc(sizeof(short) * 10);
-    if (x == NULL) {
-        fprintf(stderr, "Unable to alloc memory!\n");
-    }
-
-Bad example:
-
-    if ((x = malloc(sizeof(short)*10)) == NULL ) {
-        fprintf(stderr, "Unable to alloc memory!\n");
-    }
-
-There are exceptions to this rule. One example is walking a data structure in
-an iterator style:
-
-    while ((opt = poptGetNextOpt(pc)) != -1) {
-        ... do something with opt ...
-    }
-
-But in general, please try to avoid this pattern.
-
-
-Control-Flow changing macros
------------------------------
-
-Macros like STATUS_NOT_OK_RETURN that change control flow (return/goto/etc)
-from within the macro are considered bad, because they look like function calls
-that never change control flow. Please do not introduce them.

-mbedTLS and libssh in multithreaded applications
-==================================================
-
-To use libssh with mbedTLS in a multithreaded application, mbedTLS has to be
-built with threading support enabled.
-
-If threading support is not available and multi threading is used, ssh_init
-will fail.
-
-More information about building mbedTLS with threading support can be found
-in the mbedTLS documentation.

-Not any allowed you to import and use the functions as a powerful library,

-How to contribute a patch to libssh
-====================================
-
-Please checkout the libssh source code using git. Change the code and then
-use  "git format-patch" to create a patch. The patch should be signed (see
-below) and send it to libssh@libssh.org, or attach it to a bug report at
-https://red.libssh.org/
-
-For larger code changes, breaking the changes up into a set of simple
-patches, each of which does a single thing, are much easier to review.
-Patch sets like that will most likely have an easier time being merged
-into the libssh code than large single patches that make lots of
-changes in one large diff.
-
-Ownership of the contributed code
-==================================
-
-libssh is a project with distributed copyright ownership, which means
-we prefer the copyright on parts of libssh to be held by individuals
-rather than corporations if possible. There are historical legal
-reasons for this, but one of the best ways to explain it is that it's
-much easier to work with individuals who have ownership than corporate
-legal departments if we ever need to make reasonable compromises with
-people using and working with libssh.
-
-We track the ownership of every part of libssh via http://git.libssh.org,
-our source code control system, so we know the provenance of every piece
-of code that is committed to libssh.
-
-So if possible, if you're doing libssh changes on behalf of a company
-who normally owns all the work you do please get them to assign
-personal copyright ownership of your changes to you as an individual,
-that makes things very easy for us to work with and avoids bringing
-corporate legal departments into the picture.
-
-If you can't do this we can still accept patches from you owned by
-your employer under a standard employment contract with corporate
-copyright ownership. It just requires a simple set-up process first.
-
-We use a process very similar to the way things are done in the Linux
-Kernel community, so it should be very easy to get a sign off from
-your corporate legal department. The only changes we've made are to
-accommodate the license we use, which is LGPLv2 (or later) whereas the
-Linux kernel uses GPLv2.
-
-The process is called signing.
-
-How to sign your work
-----------------------
-
-Once you have permission to contribute to libssh from your employer, simply
-email a copy of the following text from your corporate email address to:

-#                    )
-#
-# ``target_name``:
-#   Required, expects the name of the file to receive the generated symbol
-#   version script. It should be added as a dependency for the library. Use the
-#   linker option ``--version-script filename`` to add the version information
-#   to the symbols when building the library.
-#
-# ``RELEASE_NAME_VERSION``:
-#   Required, expects a string containing the name and version information to be
-#   added to the symbols in the format ``lib_name_1_2_3``.
-#
-# ``SYMBOLS``:
-#   Required, expects a target with the property ``LIST_FILE`` containing a path
-#   to a file containing the list of symbols to be added to the symbol version
-#   script.
-#
-# ``CURRENT_MAP``:
-#   Optional. If given, the new set of symbols will be checked against the
-#   ones contained in the ``cur_map`` file and updated properly. If an
-#   incompatible change is detected and ``BREAK_ABI`` is not defined, the build
-#   will fail.
-#
-# ``FINAL``:
-#   Optional. If given, will provide the ``--final`` option to ``abimap`` tool,
-#   which will mark the modified release in the symbol version script with a
-#   special comment, preventing later changes. This option should be set when
-#   creating a library release and the resulting map file should be stored with
-#   the source code.
-#
-# ``BREAK_ABI``:
-#   Optional. If provided, will use ``abimap`` ``--allow-abi-break`` option, which
-#   accepts incompatible changes to the set of symbols. This is necessary if any
-#   previously existing symbol were removed.
-#
-# ``COPY_TO``:
-#   Optional, expects a string containing the path to where the generated
-#   map file will be copied.
-#
-# Example:
-#
-# .. code-block:: cmake
-#
-#   find_package(ABIMap)
-#   generate_map_file("lib.map"
-#                     RELEASE_NAME_VERSION "lib_1_0_0"

-#                    )
-#
-# Where the target ``symbols`` has its property ``LIST_FILE`` set to the path to
-# a file containing::
-#
-#  ``symbol1``
-#  ``symbol2``
-#
-# This example would result in the symbol version script to be created in

-# ``target_name``:
-#   Required, expects the name of the target to be created. A file named as
-#   ``${target_name}.list`` will be created in
-#   ``${CMAKE_CURRENT_BINARY_DIR}`` to receive the list of files found.
-#
-# ``DIRECTORIES``:
-#   Required, expects a list of directories paths. Only absolute paths are
-#   supported.
-#
-# ``FILES_PATTERN``:
-#   Required, expects a list of matching expressions to find the files to be
-#   considered in the directories.
-#
-# ``COPY_TO``:
-#   Optional, expects a string containing the path to where the file containing
-#   the list of files will be copied.
-#
-# This command searches the directories provided in ``DIRECTORIES`` for files
-# matching any of the patterns provided in ``FILES_PATTERNS``. The obtained list
-# is written to the path specified by ``output``. A target named ``target_name``

-#
-# ``HEADERS_LIST``:
-#   Required, expects a target with the property ``LIST_FILE`` set, containing a
-#   file path. Such file must contain a list of files paths.
-#
-# ``FILTER_PATTERN``:
-#   Optional, expects a string. Only the lines containing the filter pattern
-#   will be considered.
-#
-# ``COPY_TO``:
-#   Optional, expects a string containing the path to where the file containing
-#   the found symbols will be copied.
-#
-# This command extracts the symbols from the files listed in
-# ``headers_list`` and write them on the ``output`` file. If ``pattern``

-#
-#   API_FUNCTION int exported_func1(int a, int b);
-#
-# ``header2.h`` contains::
-#
-#   API_FUNCTION int exported_func2(int a);
-#
-#   int private_func2(int b);
-#

-1. Introduction
-
-This document describes the key exchange methode curve25519-sha256@libssh.org
-for SSH version 2 protocol. It is provided as an alternative to the existing
-key exchange mechanisms based on either Diffie-Hellman or Elliptic Curve Diffie-
-Hellman [RFC5656].
-The reason is the following : During summer of 2013, revelations from ex-
-consultant at NSA Edward Snowden gave proof that NSA willingly inserts backdoors
-into softwares, hardware components and published standards. While it is still
-believed that the mathematics behind ECC cryptography are still sound and solid,
-some people (including Bruce Schneier [SCHNEIER]), showed their lack of confidence
-in NIST-published curves such as nistp256, nistp384, nistp521, for which constant
-parameters (including the generator point) are defined without explanation. It
-is also believed that NSA had a word to say in their definition. These curves
-are not the most secure or fastest possible for their key sizes [DJB], and
-researchers think it is possible that NSA have ways of cracking NIST curves.
-It is also interesting to note that SSH belongs to the list of protocols the NSA
-claims to be able to eavesdrop. Having a secure replacement would make passive
-attacks much harder if such a backdoor exists.
-
-However an alternative exists in the form of Curve25519. This algorithm has been
-proposed in 2006 by DJB [Curve25519]. Its main strengths are its speed, its
-constant-time run time (and resistance against side-channel attacks), and its
-lack of nebulous hard-coded constants.
-
-The reference version being used in this document is the one described in
-[Curve25519] as implemented in the library NaCl [NaCl].
-This document does not attempt to provide alternatives to the ecdsa-sha1-*
-authentication keys.
-
-2. Key exchange
-
-The key exchange procedure is very similar to the one described chapter 4 of
-[RFC5656]. Public ephemeral keys are transmitted over SSH encapsulated into
-standard SSH strings.
-
-The following is an overview of the key exchange process:
-
-Client                                                            Server
-------                                                            ------
-Generate ephemeral key pair.
-SSH_MSG_KEX_ECDH_INIT          -------->                      
-                                            Verify that client public key 
-                                            length is 32 bytes.
-                                             Generate ephemeral key pair.
-                                                   Compute shared secret.
-                                         Generate and sign exchange hash.
-                               <--------           SSH_MSG_KEX_ECDH_REPLY
-Verify that server public key length is 32 bytes.
-* Verify host keys belong to server.
-Compute shared secret.
-Generate exchange hash.
-Verify server's signature.
-
-*   Optional but strongly recommanded as this protects against MITM attacks.
-
-This is implemented using the same messages as described in RFC5656 chapter 4
-
-3. Method Name
-
-The name of this key exchange method is "curve25519-sha256@libssh.org".
-
-4. Implementation considerations
-
-The whole method is based on the curve25519 scalar multiplication. In this
-method, a private key is a scalar of 256 bits, and a public key is a point
-of 256 bits.
-
-4.1. Private key generation
-
-A 32 bytes private key should be generated for each new connection,
- using a secure PRNG. The following actions must be done on the private key:
-     mysecret[0] &= 248;
-     mysecret[31] &= 127;
-     mysecret[31] |= 64;
-In order to keep the key valid. However, many cryptographic libraries will do
-this automatically.
-It should be noted that, in opposition to NIST curves, no special validation
-should be done to ensure the result is a valid and secure private key.
-
-4.2 Public key generation
-
-The 32 bytes public key of either a client or a server must be generated using
-the 32 bytes private key and a common generator base. This base is defined as 9
-followed by all zeroes:
-     const unsigned char basepoint[32] = {9};
-
-The public key is calculated using the cryptographic scalar multiplication:
-     const unsigned char privkey[32];
-     unsigned char pubkey[32];
-     crypto_scalarmult (pubkey, privkey, basepoint);
-However some cryptographic libraries may provide a combined function:
-     crypto_scalarmult_base (pubkey, privkey);
-
-It should be noted that, in opposition to NIST curves, no special validation
-should be done to ensure the received public keys are valid curves point. The
-Curve25519 algorithm ensure that every possible public key maps to a valid
-ECC Point.
-
-4.3 Shared secret generation
-
-The shared secret, k, is defined in SSH specifications to be a big integer.
-This number is calculated using the following procedure:
-
-     X is the 32 bytes point obtained by the scalar multiplication of the other
-     side's public key and the local private key scalar.
-
-     The whole 32 bytes of the number X are then converted into a big integer k.
-     This conversion follows the network byte order. This step differs from 
-     RFC5656.

-# that style
-A plain, more modern HTML style for Doxygen
-
-## Requirements
-- Doxygen (tested with version 1.8.13)
-- *optional*: a sass/scss compiler if you want to modify the style
-
-## Simple usage
-Tell Doxygen about the files for that style as shown in [doxyfile.conf](doxyfile.conf). You might need to adjust the
-paths depending on where you installed that style.
-When you run Doxygen, all files are copied into to generated HTML folder. So you don't need to keep the originals around
-unless you want to re-generate the documentation.
-
-## Advanced
-that style uses a custom javascript to hack some nice stripes into some tables. It has to be loaded from HTML. Hence you need
-to use the provided custom header. Since its default content may change when Doxygen is updated, there might be syntax error in
-the generated HTML. If this is the case, you can remove the custom header (adjust your doxyfile.conf). This has no
-disadvantages other than removing the stripes.
-
-[that_style.css](that_style.css) was generated from the scss files in the folder [sass](sass). If you want to change the style,
-use those files in order to have better control. For instance, you can easily change most colors by modifying the variables
-in the beginning of [that_style.scss](sass/that_style.scss).

 @section threads_with_libssh How to use libssh with threads
 
 libssh may be used in multithreaded applications, but under several conditions :
- - Your system must support libpthread or, in Windows environment,
-   CriticalSection based mutex control.
- - Since version 0.8.0, threads initialization is called automatically in the
-   library constructor if libssh is dynamically linked. This means it is no
-   longer necessary to call ssh_init()/ssh_finalize().
- - If libssh is statically linked, threading must be initialized by calling
-   ssh_init() before using any of libssh provided functions. This initialization
-   must be done outside of any threading context. Don't forget to call
-   ssh_finalize() to avoid memory leak
+ - Threading must be initialized during the initialization of libssh. This 
+   initialization must be done outside of any threading context.
+ - If pthreads is being used by your application (or your framework's backend),
+   you must link with libssh_threads dynamic library and initialize 
+   threading with the ssh_threads_pthreads threading object.
+ - If an other threading library is being used by your application, you must 
+   implement all the methods of the ssh_threads_callbacks_struct structure
+   and initialize libssh with it.
  - At all times, you may use different sessions inside threads, make parallel
    connections, read/write on different sessions and so on. You *cannot* use a
-   single session (or channels for a single session) in several threads at the same
+   single session (or channels for a single session) in several threads at the same 
    time. This will most likely lead to internal state corruption. This limitation is
    being worked out and will maybe disappear later.

 @subsection threads_init Initialization of threads
 
-Since version 0.8.0, it is no longer necessary to call ssh_init()/ssh_finalize()
-if libssh is dynamically linked.
+To initialize threading, you must first select the threading model you want to
+use, using ssh_threads_set_callbacks(), then call ssh_init().
 
-If libssh is statically linked, call ssh_init() before using any of libssh
-provided functions.
+@code 
+#include <libssh/callbacks.h>
+...
+ssh_threads_set_callbacks(ssh_threads_get_noop());
+ssh_init();
+@endcode
+
+ssh_threads_noop is the threading structure that does nothing. It's the
+threading callbacks being used by default when you're not using threading.
 
 @subsection threads_pthread Using libpthread with libssh
 
-Since version 0.8.0, libpthread is the default threads library used by libssh.
+If your application is using libpthread, you may simply use the libpthread
+threading backend:
 
-To use libpthread, simply link it to you application.
+@code
+#include <libssh/callbacks.h>
+...
+ssh_threads_set_callbacks(ssh_threads_get_pthread());
+ssh_init();
+@endcode
+
+However, you must be sure to link with the library ssh_threads. If 
+you're using gcc, you must use the commandline
+@code
+gcc -o output input.c -lssh -lssh_threads
+@endcode 
 
-If you are using libssh statically linked, don't forget to call ssh_init()
-before using any of libssh provided functions (and ssh_finalize() in  the end).
 
 @subsection threads_other Using another threading library
 
-Since version 0.8.0, libssh does not support custom threading libraries.
-The change makes sense since the newer versions for libcrypto (OpenSSL) and
-libgcrypt don't support custom threading libraries.
-
-The default used threading library is libpthread.
-Alternatively, in Windows environment, CriticalSection based mutex control can
-be used.
-
-If your system does not support libpthread nor CriticalSection based mutex
-control, unfortunately, you cannot use libssh in multithreaded scenarios.
+You must find your way in the ssh_threads_callbacks_struct structure. You must
+implement the following methods :
+- mutex_lock
+- mutex_unlock
+- mutex_init
+- mutex_destroy
+- thread_id
 
 Good luck !
