... introduced in curl-7_48_0-293-g2968c83:
Error: COMPILER_WARNING:
lib/vtls/openssl.c: scope_hint: In function ‘Curl_ossl_check_cxn’
lib/vtls/openssl.c:767:15: warning: conversion to ‘int’ from ‘ssize_t’

- In the case of recv error, limit returning 'connection still in place'
to EINPROGRESS, EAGAIN and EWOULDBLOCK.
This is an improvement on the parent commit which changed the openssl
connection check to use recv MSG_PEEK instead of SSL_peek.
Ref: https://github.com/curl/curl/commit/856baf5#comments
|
|
Calling SSL_peek can cause bytes to be read from the raw socket which in
turn can upset the select machinery that determines whether there's data
available on the socket.
Since Curl_ossl_check_cxn only tries to determine whether the socket is
alive and doesn't actually need to see the bytes SSL_peek seems like
the wrong function to call.
We're able to occasionally reproduce a connect timeout due to this
bug. What happens is that Curl doesn't know to call SSL_connect again
after the peek happens since data is buffered in the SSL buffer and thus
select won't fire for this socket.
Closes #795

Only protocols that actually have a protocol registered for ALPN and NPN
should try to get that negotiated in the TLS handshake. That is only
HTTPS (well, http/1.1 and http/2) right now. Previously ALPN and NPN
would wrongly be used in all handshakes if libcurl was built with it
enabled.

OpenSSL 1.1.0-pre seems to return NULL(?) for a whole lot of those

The RSA, DSA and DH structs are now opaque and require use of new APIs
Fixes #763
|
|
When compiling with OpenSSL 1.1.0 (so that the HAVE_X509_GET0_SIGNATURE
&& HAVE_X509_GET0_EXTENSIONS pre-processor block is active), Visual C++
14 complains:
warning C4701: potentially uninitialized local variable 'palg' used
warning C4701: potentially uninitialized local variable 'psig' used
|
|
... so we don't need extra boringssl precautions for for
HAVE_ERR_REMOVE_THREAD_STATE_NOARG.

As of https://boringssl-review.googlesource.com/#/c/6980/, almost all of
BoringSSL #ifdefs in cURL should be unnecessary:
- BoringSSL provides no-op stubs for compatibility which replaces most
#ifdefs.
- DES_set_odd_parity has been in BoringSSL for nearly a year now. Remove
the compatibility codepath.
- With a small tweak to an extend_key_56_to_64 call, the NTLM code
builds fine.
- Switch OCSP-related #ifdefs to the more generally useful
OPENSSL_NO_OCSP.
The only #ifdefs which remain are Curl_ossl_version and the #undefs to
work around OpenSSL and wincrypt.h name conflicts. (BoringSSL leaves
that to the consumer. The in-header workaround makes things sensitive to
include order.)
This change errs on the side of removing conditionals despite many of
the restored codepaths being no-ops. (BoringSSL generally adds no-op
compatibility stubs when possible. OPENSSL_VERSION_NUMBER #ifdefs are
bad enough!)
Closes #640

When trying to verify a peer without having any root CA certificates
set, this makes libcurl use the TLS library's built in default as
fallback.

sk_X509_EXTENSION_num may return an unsigned integer, however the value

... by extracting the LIB + REASON from the OpenSSL error code. OpenSSL
1.1.0+ returned a new func number of another cerfificate fail so this
required a fix and this is the better way to catch this error anyway.

Curl_ossl_init calls OPENSSL_load_builtin_modules() but
Curl_ossl_cleanup doesn't make a call to free these modules.

They tend to never get updated anyway so they're frequently inaccurate
and we never go back to revisit them anyway. We document issues to work
on properly in KNOWN_BUGS and TODO instead.

Simplify by removing #ifdefs and macros

|
We only support >= 0.9.7
|
|
|
|
BoringSSL implements `BIO_get_mem_data` as a function, instead of a
macro, and expects the output pointer to be a `char **`. We have to add
an explicit cast to grab the pointer as a `const char **`.

This reverts commit 370ee919b37cc9a46c36428b2bb1527eae5db2bd.
Issue #509 has all the details but it was confirmed that the crash was
not due to this, so the previous commit was wrong.

After a successful call to SSL_CTX_use_PrivateKey(), we must not call

sk_X509_pop will decrease the size of the stack which means that the loop would
end after having added only half of the certificates.
Also make sure that the X509 certificate is freed in case
SSL_CTX_add_extra_chain_cert fails.

- Change algorithm init to happen after OpenSSL config load.
Additional algorithms may be available due to the user's config so we
