- Fix race condition with BIO methods initialization in libpq with threads
-
- The libpq code in charge of creating per-connection SSL objects was
- prone to a race condition when loading the custom BIO methods needed by
- my_SSL_set_fd(). As BIO methods are stored as a static variable, the
- initialization of a connection could fail because it could be possible
- to have one thread refer to my_bio_methods while it is being manipulated
- by a second concurrent thread.
-
- This error has been introduced by 8bb14cdd33de, that has removed
- ssl_config_mutex around the call of my_SSL_set_fd(), that itself sets
- the custom BIO methods used in libpq. Like previously, the BIO method
- initialization is now protected by the existing ssl_config_mutex, itself
- initialized earlier for WIN32.
-
- While on it, document that my_bio_methods is protected by
- ssl_config_mutex, as this can be easy to miss.

-
- Use BIO_{get,set}_app_data instead of BIO_{get,set}_data.
-
- We should have done it this way all along, but we accidentally got
- away with using the wrong BIO field up until OpenSSL 3.2. There,
- the library's BIO routines that we rely on use the "data" field
- for their own purposes, and our conflicting use causes assorted
- weird behaviors up to and including core dumps when SSL connections
- are attempted. Switch to using the approved field for the purpose,
- i.e. app_data.
-
- While at it, remove our configure probes for BIO_get_data as well
- as the fallback implementation. BIO_{get,set}_app_data have been
- there since long before any OpenSSL version that we still support,
- even in the back branches.
-
- Also, update src/test/ssl/t/001_ssltests.pl to allow for a minor
- change in an error message spelling that evidently came in with 3.2.
-
- Tristan Partin and Bo Andreson. Back-patch to all supported branches.

- Be more wary about OpenSSL not setting errno on error.
-
- OpenSSL will sometimes return SSL_ERROR_SYSCALL without having set
- errno; this is apparently a reflection of recv(2)'s habit of not
- setting errno when reporting EOF. Ensure that we treat such cases
- the same as read EOF. Previously, we'd frequently report them like
- "could not accept SSL connection: Success" which is confusing, or
- worse report them with an unrelated errno left over from some
- previous syscall.
-
- To fix, ensure that errno is zeroed immediately before the call,
- and report its value only when it's not zero afterwards; otherwise
- report EOF.
-
- For consistency, I've applied the same coding pattern in libpq's
- pqsecure_raw_read(). Bare recv(2) shouldn't really return -1 without
- setting errno, but in case it does we might as well cope.
-
- Per report from Andres Freund. Back-patch to all supported versions.
