From f1e9f510ec70f2bb64f1b61b2b040d8d3103af32 Mon Sep 17 00:00:00 2001 From: Werner Koch Date: Tue, 12 Apr 2011 16:30:08 +0200 Subject: Add code for explicit selection of pooled A records. To better cope with round robin pooled A records like keys.gnupg.net we need to keep some information on unresponsive hosts etc. What we do now is to resolve the hostnames, remember them and select a random one. If a host is dead it will be marked and a different one selected. This is intended to solve the problem of long timeouts due to unresponsive hosts. The code is not yet finished but selection works. --- common/sysutils.c | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'common/sysutils.c') diff --git a/common/sysutils.c b/common/sysutils.c index a94d1fca5..648e70fe6 100644 --- a/common/sysutils.c +++ b/common/sysutils.c @@ -150,6 +150,17 @@ get_session_marker (size_t *rlen) return marker; } +/* Return a random number in an unsigned int. */ +unsigned int +get_uint_nonce (void) +{ + unsigned int value; + + gcry_create_nonce (&value, sizeof value); + return value; +} + + #if 0 /* not yet needed - Note that this will require inclusion of cmacros.am in Makefile.am */ -- cgit v1.2.3
