From efa8f606402c3d7ca361932418cbcc2600b6c059 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Tue, 28 Nov 2023 12:34:03 -0500 Subject: [PATCH] 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.
