From efacfbcb6c88677809f44a574fbcd9824835dccb Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sat, 12 Nov 2005 12:12:05 -0800 Subject: [PATCH] [IPV6]: Fix rtnetlink dump infinite loop The recent change to netlink dump "done" callback handling broke IPv6 which played dirty tricks with the "done" callback. This causes an infinite loop during a dump. The following patch fixes it. This bug was reported by Jeff Garzik. Signed-off-by: Herbert Xu Signed-off-by: David S.
