08c33d6aeb threads: Fix building with POSIX threads in MinGW.
BUG: https://red.libssh.org/issues/181

Originally written by Patrick von Reth <vonreth () kde ! org>.

This patch is part of the larger patch:
https://projects.kde.org/projects/kdesupport/emerge/repository/revisions/master/changes/portage/win32libs/libssh/0002-add-a-way-to-test-ssh-connections-on-windows.patch

MinGW (in particular, the MinGW-w64 fork) can use either posix threads
or win32 threads. This patch fixes the MinGW build when using posix
threads.

8fe36e3d07 pki crypto: expose new ssh_pki_key_ecdsa_name API
Enable retrieving the "ecdsa-sha2-nistpNNN" name of ECDSA keys with a
new 'ssh_pki_key_ecdsa_name' API.  This gives more information than the
'ssh_key_type_to_char' API, which yields "ssh-ecdsa" for ECDSA keys.
The motivation is that this info is useful to have in a server context.

The torture_pki unit test is updated to include the new API, and a few
more passes are added to additionally test 384 and 521-bit keys.

3fdd82f2a8 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.

e7f831f0a3 packet: Do not decrypt zero length rest of buffer
If we receive a packet of length exactly blocksize, then
packet_decrypt gets called on a buffer of size 0.  The check at the
beginning of packet_decrypt indicates that the function should be
called on buffers of at least one blocksize, though the check allows
through zero length.  As is packet_decrypt can return -1 when len is 0
because malloc can return NULL in this case: according to the ISO C
standard, malloc is free to return NULL or a pointer that can be freed
when size == 0, and uclibc by default will return NULL here (in
"non-glibc-compatible" mode).  The net result is that when using
uclibc connections with libssh can anomalously fail.

Alternatively, packet_decrypt (and probably packet_encrypt for
consistency) could be made to always succeed on len == 0 without
depending on the behavior of malloc.

Thanks to Josh Berlin for bringing conneciton failures with uclibc to
my attention.

4ea4e12df2 build: Use Threads_FOUND to decide whether to build ssh_threads.
Follow-up to 4e04ec8, which caused a regression on OS X.

Checking the value of CMAKE_THREAD_LIBS_INIT to decide whether any threading
library is present on a system turns out to be wrong -- in OS X, for
example, usage of pthreads does not depend on any additional linker or
compiler flags, so CMAKE_THREAD_LIBS_INIT is empty and our check in
src/CMakeLists.txt failed (it used to work before 4e04ec8 because
CMAKE_HAVE_THREADS_LIBRARY is set).

Instead, just look for Threads_FOUND, which FindThreads sets just like any
other Find module when it has found what it was looking for.

c571cd8402 threads: Be less strict when deciding whether to build libssh_threads.
As mentioned in the previous commit, there are cases where
CMAKE_HAVE_THREADS_LIBRARY is not set and pthreads _is_ being used: one can
pass -DTHREADS_HAVE_PTHREAD_ARG=1 to CMake directly so that it just passes
-pthread to the compiler/linker and does not set CMAKE_HAVE_THREADS_LIBRARY.

Since we are only interested in knowing whether any threading library has
been found, we should use CMAKE_THREAD_LIBS_INIT instead (Threads_FOUND
would also work).

Note that, at the moment, there is only a pthreads backend available in
threads/, so if it is not found configuration will fail because CMake will
try to create a library from an empty set of source files.

default as a way to skip the checks for -lpthread, -lpthreads and others and
tell the build system that -pthread is the one expected to be used).

785682ac28 socket: fix read of non-connected socket
Ensure to check whether the socket at hand is indeed still connected
throughout POLLIN processing in ssh_socket_pollcallback.

Before this change, the POLLIN block in ssh_socket_pollcallback is
predicated against the condition (s->state == SSH_SOCKET_CONNECTED).
Once entered, data from the socket is consumed through the data
callback in this loop:

  do {
    r = s->callbacks->data(buffer_get_rest(s->in_buffer),
                           buffer_get_rest_len(s->in_buffer),
                           s->callbacks->userdata);
    buffer_pass_bytes(s->in_buffer,r);
  } while (r > 0);

However, it is possible for the socket data callback to change the
state of the socket (closing it, for example).  Fix the loop to only
continue so long as the socket remains connected: this also entails
setting the ssh_socket state to SSH_SOCKET_CLOSED upon close.

The bug can be observed before the change by sending a bogus banner
to the server: 'echo -e "A\r\nB\r\n" | nc localhost 22'.  Each of
'A' and 'B' will be processed by 'callback_receive_banner', even
though the client socket is closed after rejection of 'A'.

18506f697c pki_crypto: fix DSA signature extraction
Fix the DSA portion of 'pki_signature_to_blob': before this change, it
is possible to sometimes observe DSA signature validation failure when
testing with OpenSSH clients.  The problem ended up being the following
snippet which did not account for the case when 'ssh_string_len(x)' may
be less than 20:

  r = make_bignum_string(sig->dsa_sig->r);
  ...
  memcpy(buffer,
         ((char *) ssh_string_data(r)) + ssh_string_len(r) - 20,
         20);

Above consider the case that ssh_string_len(r) is 19; in that case the
memcpy unintentionally starts in the wrong place.  The same situation
can happen for value 's' in this code.

To fix, adjust the offsets used for the input and output pointers, taking
into account that the lengths of 'r' and 's' can be less than 20.  With
the fix I am no longer able to reproduce the original failure mode.

   ssh_packet_userauth_request: ssh_packet_userauth_request: Received an invalid  signature from peer

  http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/ssh-rsa.c?rev=1.19;content-type=text%2Fx-cvsweb-markup

Before this change, a double free can happen via 'ssh_bind_free'

  // create an ssh_bind
  ssh_bind b = ssh_bind_new();

  // provide a path to a wrong key-type
  ssh_bind_options_set(b, SSH_BIND_OPTIONS_DSAKEY, path_to_rsa_key);

  // initialize set key-type
  ssh_bind_listen(b);

    -> error path "The DSA host key has the wrong type: %d",

       ssh_key_free(sshbind->dsa)

         -> ssh_key_clean(key) // OK

         -> SAFE_FREE(key)     // OK, but, sshbind->dsa is *not* set to NULL

  // ssh_bind_listen failed, so clean up ssh_bind
  ssh_bind_free(b);

    -> ssh_key_free(sshbind->dsa)  // double-free here

To fix, set pointers to NULL that have been free'd with 'ssh_key_free'.

Per RFC 4252, it is required to send back only one of either
SSH_MSG_USERAUTH_PK_OK or SSH_MSG_USERAUTH_FAILURE for public
key probes.

Update the handling of 'auth_pubkey_function' to send back PK_OK
instead of SSH_MSG_USERAUTH_SUCCESS for the case that the state
of the message at hand is SSH_PUBLICKEY_STATE_NONE.

With this change, it is now possible to process an initial key probe
and then subsequent signature validation using the server callbacks.

Coding Style Conventions
========================
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 [1] with one
excecption, we use 4 spaces instead of tabs. This closely matches what most
libssh developers use already anyways, with a few exceptions as mentioned
below.
To shorthen this 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 whitespaces
* 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?
Editors
========
VIM
----
set ts=4 sw=4 et cindent
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.\+/'

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 its 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 youre 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 cant 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 weve 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:
contributing@libssh.org
--------------------------------------------------------------------------
libssh Developer's Certificate of Origin. Version 1.0
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the appropriate
version of the GNU General Public License; or
(b) The contribution is based upon previous work that, to the best of
my knowledge, is covered under an appropriate open source license
and I have the right under that license to submit that work with
modifications, whether created in whole or in part by me, under
the GNU General Public License, in the appropriate version; or
(c) The contribution was provided directly to me by some other
person who certified (a) or (b) and I have not modified it.
(d) I understand and agree that this project and the contribution are
public and that a record of the contribution (including all
metadata and personal information I submit with it, including my
sign-off) is maintained indefinitely and may be redistributed
consistent with the libssh Team's policies and the requirements of
the GNU GPL where they are relevant.
(e) I am granting this work to this project under the terms of the
GNU Lesser General Public License as published by the
Free Software Foundation; either version 2.1 of
the License, or (at the option of the project) any later version.
http://www.gnu.org/licenses/lgpl-2.1.html
--------------------------------------------------------------------------
We will maintain a copy of that email as a record that you have the rights to
contribute code to libssh under the required licenses whilst working for the
company where the email came from.
Then when sending in a patch via the normal mechanisms described above, add a
line that states:
Signed-off-by: Random J Developer <random@developer.example.org>
using your real name and the email address you sent the original email you used
to send the libssh Developers Certificate of Origin to us (sorry, no
pseudonyms or anonymous contributions.)
Thats it! Such code can then quite happily contain changes that have copyright
messages such as:
(c) Example Corporation.
and can be merged into the libssh codebase in the same way as patches from any
other individual. You dont need to send in a copy of the libssh Developers
Certificate of Origin for each patch, or inside each patch. Just the sign-off
message is all that is required once weve received the initial email.
Have fun and happy libssh hacking!

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

Why not ? :) I've began to work on my own implementation of the ssh protocol
because i didn't like the currently public ones.
Not any allowed you to import and use the functions as a powerful library,
and so i worked on a library-based SSH implementation which was non-existing
in the free and open source software world.

# FindABIMap
# ----------
#
# This file provides functions to generate the symbol version script. It uses
# the ``abimap`` tool to generate and update the linker script file. It can be
# installed by calling::
#
# $ pip install abimap
#
# The ``function generate_map_file`` generates a symbol version script
# containing the provided symbols. It defines a custom command which sets
# ``target_name`` as its ``OUTPUT``.
#
# The experimental function ``extract_symbols()`` is provided as a simple
# parser to extract the symbols from C header files. It simply extracts symbols
# followed by an opening '``(``'. It is recommended to use a filter pattern to
# select the lines to be considered. It defines a custom command which sets
# ``target_name`` as its output.
#
# The helper function ``get_files_list()`` is provided to find files given a
# name pattern. It defines a custom command which sets ``target_name`` as its
# output.
#
# Functions provided
# ------------------
#
# ::
#
# generate_map_file(target_name
# RELEASE_NAME_VERSION release_name
# SYMBOLS symbols_target
# [CURRENT_MAP cur_map]
# [FINAL]
# [BREAK_ABI]
# [COPY_TO output]
# )
#
# ``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"
# SYMBOLS symbols
# )
#
# 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
# ``${CMAKE_CURRENT_BINARY_DIR}/lib.map`` containing the provided symbols.
#
# ::
#
# get_files_list(target_name
# DIRECTORIES dir1 [dir2 ...]
# FILES_PATTERNS exp1 [exp2 ...]
# [COPY_TO output]
# )
#
# ``target_name``:
# Required, expects the name of the target to be created. A file named as
# ``${target_name}.list`` will be created in
# ``${CMAKE_CURRENT_BINARY_DIR}`` to receive the list of files found.
#
# ``DIRECTORIES``:
# Required, expects a list of directories paths. Only absolute paths are
# supported.
#
# ``FILES_PATTERN``:
# Required, expects a list of matching expressions to find the files to be
# considered in the directories.
#
# ``COPY_TO``:
# Optional, expects a string containing the path to where the file containing
# the list of files will be copied.
#
# This command searches the directories provided in ``DIRECTORIES`` for files
# matching any of the patterns provided in ``FILES_PATTERNS``. The obtained list
# is written to the path specified by ``output``. A target named ``target_name``
# will be created and its property ``LIST_FILE`` will be set to contain
# ``${CMAKE_CURRENT_BINARY_DIR}/${target_name}.list``
#
# Example:
#
# .. code-block:: cmake
#
# find_package(ABIMap)
# get_files_list(target
# DIRECTORIES "/include/mylib"
# FILES_PATTERNS "*.h"
# COPY_TO "my_list.txt"
# )
#
# Consider that ``/include/mylib`` contains 3 files, ``h1.h``, ``h2.h``, and
# ``h3.hpp``
#
# Will result in a file ``my_list.txt`` containing::
#
# ``h1.h;h2.h``
#
# And the target ``target`` will have its property ``LIST_FILE`` set to contain
# ``${CMAKE_CURRENT_BINARY_DIR}/target.list``
#
# ::
#
# extract_symbols(target_name
# HEADERS_LIST headers_list_target
# [FILTER_PATTERN pattern]
# [COPY_TO output]
# )
#
# ``target_name``:
# Required, expects the name of the target to be created. A file named after
# the string given in ``target_name`` will be created in
# ``${CMAKE_CURRENT_BINARY_DIR}`` to receive the list of symbols.
#
# ``HEADERS_LIST``:
# Required, expects a target with the property ``LIST_FILE`` set, containing a
# file path. Such file must contain a list of files paths.
#
# ``FILTER_PATTERN``:
# Optional, expects a string. Only the lines containing the filter pattern
# will be considered.
#
# ``COPY_TO``:
# Optional, expects a string containing the path to where the file containing
# the found symbols will be copied.
#
# This command extracts the symbols from the files listed in
# ``headers_list`` and write them on the ``output`` file. If ``pattern``
# is provided, then only the lines containing the string given in ``pattern``
# will be considered. It is recommended to provide a ``FILTER_PATTERN`` to mark
# the lines containing exported function declaration, since this function is
# experimental and can return wrong symbols when parsing the header files. A
# target named ``target_name`` will be created with the property ``LIST_FILE``
# set to contain ``${CMAKE_CURRENT_BINARY_DIR}/${target_name}.list``.
#
# Example:
#
# .. code-block:: cmake
#
# find_package(ABIMap)
# extract_symbols("lib.symbols"
# HEADERS_LIST "headers_target"
# FILTER_PATTERN "API_FUNCTION"
# )
#
# Where ``LIST_FILE`` property in ``headers_target`` points to a file
# containing::
#
# header1.h;header2.h
#
# Where ``header1.h`` contains::
#
# API_FUNCTION int exported_func1(int a, int b);
#
# ``header2.h`` contains::
#
# API_FUNCTION int exported_func2(int a);
#
# int private_func2(int b);
#
# Will result in a file ``lib.symbols.list`` in ``${CMAKE_CURRENT_BINARY_DIR}``
# containing::
#
# ``exported_func1``
# ``exported_func2``

#
# Generates a symbols version script using the abimap tool.
# This script is run in build time to use the correct command depending on the
# existence of the file provided ``CURRENT_MAP``.

# existing map. Otherwise, the ``abimap new`` subcommand is used to create a new
# map file.
#

# This is required because ``abimap`` do not generate output if no symbols were
# changed when updating an existing file.

# Required, expects the library name and version information to be added to

#

# - Run Doxygen
#
# Adds a doxygen target that runs doxygen to generate the html
# and optionally the LaTeX API documentation.
# The doxygen target is added to the doc target as a dependency.
# i.e.: the API documentation is built with:
# make doc
#
# USAGE: GLOBAL INSTALL
#
# Install it with:
# cmake ./ && sudo make install
# Add the following to the CMakeLists.txt of your project:
# include(UseDoxygen OPTIONAL)
# Optionally copy Doxyfile.in in the directory of CMakeLists.txt and edit it.
#
# USAGE: INCLUDE IN PROJECT
#
# set(CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR})
# include(UseDoxygen)
# Add the Doxyfile.in and UseDoxygen.cmake files to the projects source directory.
#
#
# CONFIGURATION
#
# To configure Doxygen you can edit Doxyfile.in and set some variables in cmake.
# Variables you may define are:
# DOXYFILE_SOURCE_DIR - Path where the Doxygen input files are.
# Defaults to the current source directory.
# DOXYFILE_EXTRA_SOURCES - Additional source diretories/files for Doxygen to scan.
# The Paths should be in double quotes and separated by space. e.g.:
# "${CMAKE_CURRENT_BINARY_DIR}/foo.c" "${CMAKE_CURRENT_BINARY_DIR}/bar/"
#
# DOXYFILE_OUTPUT_DIR - Path where the Doxygen output is stored.
# Defaults to "${CMAKE_CURRENT_BINARY_DIR}/doc".
#
# DOXYFILE_LATEX - ON/OFF; Set to "ON" if you want the LaTeX documentation
# to be built.
# DOXYFILE_LATEX_DIR - Directory relative to DOXYFILE_OUTPUT_DIR where
# the Doxygen LaTeX output is stored. Defaults to "latex".
#
# DOXYFILE_HTML_DIR - Directory relative to DOXYFILE_OUTPUT_DIR where
# the Doxygen html output is stored. Defaults to "html".

# 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
libgcrypt 1.6 and bigger backend does not support custom callback. Using anything else than pthreads (ssh_threads_get_pthread()) here will fail.
Good luck !
