- add special sauce to disable unwanted peer verification by mbedtls
when negotiating TLS v1.3
- add special sauce for MBEDTLS_ERR_SSL_RECEIVED_NEW_SESSION_TICKET
return code on *writing* TLS data. We assume the data had not been
written and EAGAIN.
- return correct Curl error code when peer verification failed.
- disable test_08_05 with 50 HTTP/1.1 connections, as mbedtls reports a
memory allocation failed during handshake.
- bump CI mbedtls version to 3.6.0
Fixes#13653Closes#13838
- similar to openssl, use a shared 'credentials' instance
among TLS connections with a plain configuration.
- different to openssl, a connection with a client certificate
is not eligible to sharing.
- document CURLOPT_CA_CACHE_TIMEOUT in man page
Closes#13795
Previously a large table of ciphers was used to determine the default
ciphers and to lookup manually selected ciphers names.
With the lookup of the manually selected cipher names moved to
Curl_cipher_suite_walk_str() the large table is no longer needed for
that purpose.
The list of manually selected cipher can now be intersected with the
ciphers supported by Secure Transport (SSLGetSupportedCiphers()),
instead of using the fixed table for that.
The other use of the table was to filter the list of all supported
ciphers offered by Secure Transport to create a list of ciphers to
use by default, excluding ciphers in the table marked as weak.
Instead of using a complement based approach (exclude weak), switch
to using an intersection with a smaller list of ciphers deemed
appropriate.
Closes#13823
The versions check wrongly complained and return error if the *minimum*
version was set to something less than 1.3. QUIC is always TLS 1.3, but
that means minimum 1.2 is still fine to ask for.
This also renames the local variable to make the mistake harder to make
in the future.

Fixes#13799Closes#13802
local ftp upload tests sometimes failed with an invalid TLS record being
reported by gnutls. vsftp did log that the shutdown was not regarded as
clean, failing the control connection thereafter.
These changes make test_31_05 work reliable locally.
- on closing the SSL filter, shutdown READ *and* WRITE
- on closing, try a receive after shutdown is sent
- convert to DEBUGF to CURL_TRC_CF
Closes#13790
- add `Curl_hash_add2()` that passes a destructor function for
the element added. Call element destructor instead of hash
destructor if present.
- multi: add `proto_hash` for protocol related information,
remove `struct multi_ssl_backend_data`.
- openssl: use multi->proto_hash to keep x509 shared store
- schannel: use multi->proto_hash to keep x509 shared store
- vtls: remove Curl_free_multi_ssl_backend_data() and its
equivalents in the TLS backends
Closes#13345
- Don't call the keylog function if it has already logged the key.
For old OpenSSL versions and its forks that do not have support for
OpenSSL's keylog callback, libcurl has its own legacy key logging
function that logs the TLS 1.2 (and earlier) key (client random + master
key) on a single line.
Prior to this change, since e7de80e8 (precedes 8.8.0), the legacy key
logging function could write the same key line more than once (usually
twice) due to some incorrect logic.
Closes https://github.com/curl/curl/pull/13683
- send the TLS close notify message when cloding down
the mbedtls connection filter
- this is a "least" effort version and, as other TLS filters,
is lacking a graceful send/receive/timeout for a really
clean shutdown.
Closes#13745
- Revert to the legacy TLS 1.2 key logging code for LibreSSL.
- Document SSLKEYLOGFILE for LibreSSL is TLS 1.2 max.
Prior to this change if the user specified a filename in the
SSLKEYLOGFILE environment variable and was using LibreSSL 3.5.0+ then
an empty file would be created and no keys would be logged.
This is effectively a revert of e43474b4 which changed openssl.c to use
SSL_CTX_set_keylog_callback for LibreSSL 3.5.0+. Unfortunately LibreSSL
added that function only as a stub that doesn't actually do anything.

Fixes https://github.com/curl/curl/issues/13672
Closes https://github.com/curl/curl/pull/13682
- rustls report it has finished the TLS handshake *before*
all relevant data has been sent off, e.g. it FINISHED message
- On connections the send data immediately, this was never noticed
as the FINISHED in rustls buffers was send with the app data
- On passive FTP connections, curl does not send any data after
the handshake, leaving FINISHED unsent and the server never
responded as it was waiting on this.
Closes#13686
When TLS bytes could not completely sent off, the amount of plain bytes
already added to rustls were forgotten. This lead to send those byte
duplicate, corrupting the request send to the server.
Closes#13676
Take advantage of the Curl_cipher_suite_walk_str() and
Curl_cipher_suite_get_str() functions introduced in commit fba9afeb.
This also fixes CURLOPT_SSL_CIPHER_LIST not working at all for bearssl
due to commit ff74cef5.
Closes#13464
- connect to DNS names with trailing dot
- connect to DNS names with double trailing dot
- rustls, always give `peer->hostname` and let it
figure out SNI itself
- add SNI tests for ip address and localhost
- document in code and TODO that QUIC with ngtcp2+wolfssl
does not do proper peer verification of the certificate
- mbedtls, skip tests with ip address verification as not
supported by the library
Closes#13486
- add session with destructor callback
- remove vtls `session_free` method
- let `Curl_ssl_addsessionid()` take ownership
of session object, freeing it also on failures
- change tls backend use
- test_17, add tests for SSL session resumption
Closes#13386
Use a lookup list to set the cipher suites, allowing the
ciphers to be set by either openssl or IANA names.
To keep the binary size of the lookup list down we compress
each entry in the cipher list down to 2 + 6 bytes using the
C preprocessor.
Closes#13442
The rustls backend advertises SSLSUPP_TLS13_CIPHERSUITES, but
the code does not actually seem to support it (yet?). Removed
the flag and corrected documentation.
Closes#13452
Before this patch, two macros were used to guard IPv6 features in curl
sources: `ENABLE_IPV6` and `USE_IPV6`. This patch makes the source use
the latter for consistency with other similar switches.
`-DENABLE_IPV6` remains accepted for compatibility as a synonym for
`-DUSE_IPV6`, when passed to the compiler.
`ENABLE_IPV6` also remains the name of the CMake and `Makefile.vc`
options to control this feature.
Closes#13349
- delay loading of trust anchors and CRLs after the ClientHello
has been sent off
- add tracing to IO operations
- on IO errors, return the CURLcode of the underlying filter
Closes#13339
Tests were consistently flaky for a while.

Since mbedTLS v3.6.0, the RNG check added in ssl_conf_check() will fail
if no RNG is provided when calling mbedtls_ssl_setup().
Therefore, mbedtls_ssl_conf_rng() needs to be called before the SSL
context is passed to mbedtls_ssl_setup().

- Use data->multi and not data->multi_easy to refer to the active multi.
The easy handle's active multi is always data->multi.
This is a follow up to 757dfdf which changed curl so that an easy handle
used with the easy interface and then multi interface cannot have two
different multi handles associated with it at the same time
(data->multi_easy from the easy interface and data->multi from the multi
interface).
Closes https://github.com/curl/curl/pull/12665
Reduced size of dynamically_allocated_data structure.
Reduced number of stored values in enum dupstring and enum dupblob. This
affects the reduced array placed in the UserDefined structure.

- When curl sees a TCP close from the peer, do not start a TLS shutdown.
TLS shutdown is a handshake and if the peer already closed the
connection, it is not interested in participating.
