From e51935df0ee3984a0464bfd72afc58836cb79d99 Mon Sep 17 00:00:00 2001 From: James Yonan Date: Tue, 12 Apr 2011 05:14:34 +0000 Subject: For Mac OSX, when DARWIN_USE_IPCONFIG is defined, retry ipconfig command on failure once every second for up to 15 seconds. This is necessary to work around an issue observed on OSX 10.5 where the ipconfig command sometimes fails if executed immediately after the tun device open. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@7151 e7ae566f-a301-0410-adde-c780ea21d3b5 --- tun.c | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) (limited to 'tun.c') diff --git a/tun.c b/tun.c index 8c94f89..f2dec25 100644 --- a/tun.c +++ b/tun.c @@ -801,7 +801,17 @@ do_ifconfig (struct tuntap *tt, ); } argv_msg (M_INFO, &argv); - openvpn_execve_check (&argv, es, S_FATAL, "Mac OS X ipconfig failed"); + { + int i; + const int n = 15; + for (i = 1; i <= n; ++i) /* OSX 10.5 needs retry */ + { + if (openvpn_execve_check (&argv, es, (i == n) ?
