2020-04-25libssh: avoid options override by configuration filesAnderson Toshiyuki Sasaki
Previously, options set explicitly through command line options could be overridden by the configuration files parsed automatically when ssh_connect() was called. By calling ssh_options_parse_config() explicitly, the configuration files are parsed before setting the options, avoiding the options override. Once the configuration files are parsed, the automatic configuration parsing is not executed. Fixes #4972 Closes #5283 Signed-off-by: Anderson Toshiyuki Sasaki <ansasaki@redhat.com>
2020-04-17libssh: Use new ECDSA key types to check known hostsAnderson Toshiyuki Sasaki
From libssh 0.9.0, ssh_key_type() returns different key types for ECDSA keys depending on the curve. Signed-off-by: Anderson Toshiyuki Sasaki <ansasaki@redhat.com> Fixes #5252 Closes #5253
2020-03-09sftp: fix segfault regression introduced by #4747Jim Fuller
This fix adds a defensive check for the case where the char *name in struct libssh2_knownhost is NULL Fixes #5041 Closes #5062
2020-03-07libssh: Fix matching user-specified MD5 hex keyJay Satiro
Prior to this change a match would never be successful because it was mistakenly coded to compare binary data from libssh to a user-specified hex string (ie CURLOPT_SSH_HOST_PUBLIC_KEY_MD5). Reported-by: fds242@users.noreply.github.com Fixes https://github.com/curl/curl/issues/4971 Closes https://github.com/curl/curl/pull/4974
2020-02-27libssh: improve known hosts handlingAnderson Toshiyuki Sasaki
Previously, it was not possible to get a known hosts file entry due to the lack of an API. ssh_session_get_known_hosts_entry(), introduced in libssh-0.9.0, allows libcurl to obtain such information and behave the same as when compiled with libssh2. This also tries to avoid the usage of deprecated functions when the replacements are available. The behaviour will not change if versions older than libssh-0.8.0 are used.

2020-01-11libssh2: add support for forcing a hostkey typeSantino Keupp
- Allow forcing the host's key type found in the known_hosts file. Currently, curl (with libssh2) does not take keys from your known_hosts file into account when talking to a server. With this patch the known_hosts file will be searched for an entry matching the hostname and, if found, libssh2 will be told to claim this key type from the server. Closes https://github.com/curl/curl/pull/4747

2019-12-01build: Disable Visual Studio warning "conditional expression is constant"Jay Satiro
- Disable warning C4127 "conditional expression is constant" globally in curl_setup.h for when building with Microsoft's compiler. This mainly affects building with the Visual Studio project files found in the projects dir. Prior to this change the cmake and winbuild build systems already disabled 4127 globally for when building with Microsoft's compiler. Also, 4127 was already disabled for all build systems in the limited circumstance of the WHILE_FALSE macro which disabled the warning specifically for while(0). This commit removes the WHILE_FALSE macro and all other cruft in favor of disabling globally in curl_setup. Background: We have various macros that cause 0 or 1 to be evaluated, which would cause warning C4127 in Visual Studio. For example this causes it: #define Curl_resolver_asynch() 1 Full behavior is not clearly defined and inconsistent across versions. However it is documented that since VS 2015 Update 3 Microsoft has addressed this somewhat but not entirely, not warning on while(true) for example. Prior to this change some C4127 warnings occurred when I built with Visual Studio using the generated projects in the projects dir. Closes https://github.com/curl/curl/pull/4658
2019-11-28curl_setup_once: consistently use WHILE_FALSE in macrosDaniel Gustafsson
The WHILE_FALSE construction is used to avoid compiler warnings in macro constructions. This fixes a few instances where it was not used in order to keep the code consistent. Closes #4649 Reviewed-by: Daniel Stenberg <daniel@haxx.se>
2019-11-28checksrc: fix regexp for ASSIGNWITHINCONDITIONDaniel Gustafsson
The regexp looking for assignments within conditions was too greedy and matched a too long string in the case of multiple conditionals on the same line. This is basically only a problem in single line macros, and the code which exemplified this was essentially: do { if((x) != NULL) { x = NULL; } } while(0) ..where the final parenthesis of while(0) matched the regexp, and the legal assignment in the block triggered the warning. Fix by making the regexp less greedy by matching for the tell-tale signs of the if statement ending. Also remove the one occurrence where the warning was disabled due to a construction like the above, where the warning didn't apply when fixed.
