true bug in libcurl built with OpenSSL. It made curl_easy_getinfo() more or
less always return 0 for CURLINFO_SSL_VERIFYRESULT because the function that
would set it to something non-zero would return before the assign in almost
all error cases. The internal variable is now set to non-zero from the start
of the function only to get cleared later on if things work out fine.
libraries are supported. Starting now, each underlying SSL library support
code does a set of defines for the 16 functions the generic layer (sslgen.c)
uses (all these new function defines use the prefix "curlssl_"). This
greatly simplified the generic layer in readability by involving much less
#ifdefs and other preprocessor stuff and should make it easier for people to
make libcurl work with new SSL libraries.
Hopefully I can later on document these 16 functions somewhat as well.
I also made most of the internal SSL-dependent functions (using Curl_ssl_
prefix) #defined to nothing when no SSL support is requested - previously
they would unnecessarily call mostly empty functions.
better control at the exact state of the connection's SSL status so that we
know exactly when it has completed the SSL negotiation or not so that there
won't be accidental re-uses of connections that are wrongly believed to be
in SSL-completed-negotiate state.
CURLE_PEER_FAILED_VERIFICATION (standard CURL_NO_OLDIES style), and made this
return code get used by the previous SSH MD5 fingerprint check in case it
fails.
and allow reuse by multiple protocols. Several unused error codes were
removed. In all cases, macros were added to preserve source (and binary)
compatibility with the old names. These macros are subject to removal at
a future date, but probably not before 2009. An application can be
tested to see if it is using any obsolete code by compiling it with the
CURL_NO_OLDIES macro defined.
Documented some newer error codes in libcurl-error(3)
passed to it with curl_easy_setopt()! Previously it has always just refered
to the data, forcing the user to keep the data around until libcurl is done
with it. That is now history and libcurl will instead clone the given
strings and keep private copies.
fail to connect if there is no Common Name field found in the remote cert.
We should deprecate the support for this set to 1 anyway soon, since the
feature is pointless and most likely never really used by anyone.
peer's name in the SSL certificate when built for OpenSSL. The leak happens
for libcurls with CURL_DOES_CONVERSIONS enabled that fail to convert the CN
name from UTF8.
and CURLOPT_CONNECTTIMEOUT_MS that, as their names should hint, do the
timeouts with millisecond resolution instead. The only restriction to that
is the alarm() (sometimes) used to abort name resolves as that uses full
seconds. I fixed the FTP response timeout part of the patch.
Internally we now count and keep the timeouts in milliseconds but it also
means we multiply set timeouts with 1000. The effect of this is that no
timeout can be set to more than 2^31 milliseconds (on 32 bit systems), which
equals 24.86 days. We probably couldn't before either since the code did
*1000 on the timeout values on several places already.
curl that uses the new CURLOPT_FTP_SSL_CCC option in libcurl. If enabled, it
will make libcurl shutdown SSL/TLS after the authentication is done on a
FTP-SSL operation.
