From 54a39cad841b80adbcef87b6939d793180973242 Mon Sep 17 00:00:00 2001 From: Eric Covener Date: Mon, 19 Feb 2018 20:54:58 +0000 Subject: [PATCH] 10 years after r567503 , fix this properly. The lock is created in post_config, so we can't copy it around in a merge_server_config() callback. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1824811 13f79535-47bb-0310-9956-ffa450edef68 --- CHANGES | 4 ++++ modules/ldap/util_ldap.c | 5 ++--- 2 files changed, 6 insertions(+), 3 deletions(-) diff --git a/CHANGES b/CHANGES index 31fa309f75..966646b685 100644 --- a/CHANGES +++ b/CHANGES @@ -1,6 +1,10 @@ -*- coding: utf-8 -*- Changes with Apache 2.5.1 + *) mod_ldap: Avoid possible crashes, hangs, and busy loops due to + improper merging of the cache lock in vhost config. + PR 43164 [Eric Covener] + *) core: Create a conn_config_t structure to hold an extendable core config rather than consuming the whole pointer with the connection socket.
