From 5d994da94521dd9c5812d4c8d576293fac03e466 Mon Sep 17 00:00:00 2001 From: tb Date: Sat, 13 Jan 2024 18:37:51 +0000 Subject: [PATCH] Remove mention of a refcount bug Said bug was fixed in OpenSSL 1.0.0, released 14 years ago. It is of course unsurprising that you may accidentally increment the refcount if your idiom for decrementing it is CRYPTO_add(&bio-references, -1, CRYPTO_LOCK_BIO)). --- lib/libssl/man/BIO_f_ssl.3 | 19 +------------------ 1 file changed, 1 insertion(+), 18 deletions(-) diff --git a/lib/libssl/man/BIO_f_ssl.3 b/lib/libssl/man/BIO_f_ssl.3 index 5d72def20d5..3b74a3d6a45 100644 --- a/lib/libssl/man/BIO_f_ssl.3 +++ b/lib/libssl/man/BIO_f_ssl.3 @@ -1,4 +1,4 @@ -.\" $OpenBSD: BIO_f_ssl.3,v 1.15 2024/01/13 17:50:01 tb Exp $ +.\" $OpenBSD: BIO_f_ssl.3,v 1.16 2024/01/13 18:37:51 tb Exp $ .\" full merge up to: OpenSSL f672aee4 Feb 9 11:52:40 2016 -0500 .\" selective merge up to: OpenSSL 61f805c1 Jan 16 01:01:46 2018 +0800 .\" @@ -607,20 +607,3 @@ and first appeared in SSLeay 0.9.0.
