Though I'm loathe to bring up conn->data (which was eliminated about 2 years ago) is there a better way then than the association of data like this at a bunch of seemingly arbitrary points? Yes I'm sure they're not arbitrary but I'm struggling to follow how this works. Is there a more central location where data could be assigned, like vtls for example?

I agree that this is looking for a more elegant solution. The sprinkling of those assignments in the code is not to my liking really, either.
That we got to have data everywhere is not the right design, since we now have multi-use of connections. In the connection filter chain, bytes handled often to not belong to a specific data.
So, in my view, we should get rid of data in connection IO, at least on the filter level.

Ok, changes now introduce a standard vtls way to save the current Curl_easy handle in a filter call and backends that need it use it from there.
The "standard" way now also NULLs at the end of a call, so UAFs should not happen.

Compare
- OpenSSL (and compatible)
- BearSSL
- gnutls
- mbedtls
- rustls
- schannel
- secure-transport
- wolfSSL (v5.0.0 and newer)
This leaves the only the following without HTTPS-proxy support:
- gskit
- nss
- wolfSSL (versions earlier than v5.0.0)

- support detecting wolfSSL via pkg-config (like autotools.) - detect wolfSSL version. - detect `HAVE_WOLFSSL_DES_ECB_ENCRYPT`. (needs e.g. `--enable-curl` when building wolfSSL) - detect `HAVE_WOLFSSL_FULL_BIO` and enable HTTPS-proxy feature. (needs e.g. `--enable-opensslall` when building wolfSSL) - fix to show `HTTPS-proxy` in cmake feature list. Ref: 55807e6 #9962 - fix to show `NTLM` in cmake feature list. - fix to show `smb` and `smbs` in cmake protocol list. - add wolfSSL CMake job to GHA (for macOS). - fix mqtt and wolfSSL symbol clash. ``` ./curl/lib/mqtt.c: In function 'mqtt_doing': ./curl/lib/mqtt.c:746:17: error: declaration of 'byte' shadows a global declaration [-Werror=shadow] 746 | unsigned char byte; | ^~~~ /opt/homebrew/Cellar/wolfssl/5.7.0_1/include/wolfssl/wolfcrypt/types.h:85:36: note: shadowed declaration is here 85 | typedef unsigned char byte; | ^~~~ ``` - format `FindWolfSSL.cmake` closer to neighbours. Closes #14064
