ssl_util.c: add APLOGNOs

2017-04-19T02:38:20+00:00

Start from 10027 to match the current trunk (r1791845), which will be
merged into shortly.

ssl_util.c: log which threadid callback is in use

2017-04-19T02:23:48+00:00

This should help during testing and debugging. Use APLOG_NOTICE for now,
until we fix PR60999, so that people can actually see the log message.

PR60947: try to warn affected users...

2017-04-18T00:19:34+00:00

...but at the moment, this won't actually get logged unless you're
running in debug mode, due to an unrelated bug (PR60999).

PR60947: avoid CRYPTO_THREADID_set_callback() if possible

2017-04-18T00:19:32+00:00

CRYPTO_THREADID_set_callback() is write-once, so if mod_ssl is unloaded
and reloaded into a different address, we'll crash if OpenSSL wasn't
also unloaded and reloaded at the same time. This can happen if another
module or library is using OpenSSL as well.

- OpenSSL 1.1.0 isn't affected.
- Certain platforms (Windows, BeOS, and POSIX-compliant systems) can
  make use of the default THREADID callback in OpenSSL 1.0.x.
- If the deprecated CRYPTO_set_id_callback() is available, we can use it
  instead of CRYPTO_THREADID_set_callback().

Otherwise, we have to fall back to CRYPTO_THREADID_set_callback(), but
hopefully that applies to a small percentage of users at this point.

ssl_util.c: add a couple explanatory comments

2017-04-18T00:19:30+00:00

Mark the things that are busted.

ssl_util.c: pull up duplicated code in ssl_util_thr_id()

2017-04-18T00:19:27+00:00

Should make it easier to see what's going on in the next few changes.

configure: bump thread count for the &errno test

2017-04-14T00:14:24+00:00

Increase the number of threads from three to ten. Patch by rjung.

configure: check if &errno is thread-local for OpenSSL

2017-04-11T23:59:31+00:00

This is step one for fixing, or at least mitigating, PR60947. Determine
which platforms can use the default OpenSSL (1.0.x) threadid-callback,
by recording the address of errno for several threads and testing that
they're all different.

The result of this test is put into the new macro,
AP_OPENSSL_USE_ERRNO_THREADID.

Feature branch for PR60947.

If the lingering close does not leave the socket in a disconnected state,

do not recycle the socket.
