* pgsql: pgcrypto: avoid recursive ResourceOwnerForget(). @ 2026-06-22 16:59 Tom Lane <tgl@sss.pgh.pa.us> 0 siblings, 0 replies; 3+ messages in thread From: Tom Lane @ 2026-06-22 16:59 UTC (permalink / raw) To: pgsql-committers@lists.postgresql.org pgcrypto: avoid recursive ResourceOwnerForget(). Raising an error within a function using an OSSLCipher object led to a complaint from ResourceOwnerForget and then a double-free crash, because ResOwnerReleaseOSSLCipher forgot to unhook the OSSLCipher object from its owner. (The sibling logic for OSSLDigest objects got this right, as did every other ReleaseResource function AFAICS.) Oversight in cd694f60d.
