From 94eb0858c2b938549d9d1703c872c6149901e7dd Mon Sep 17 00:00:00 2001 From: Maria Matejka Date: Sat, 19 Jun 2021 20:50:18 +0200 Subject: Converting the former BFD loop to a universal IO loop and protocol loop. There is a simple universal IO loop, taking care of events, timers and sockets. Primarily, one instance of a protocol should use exactly one IO loop to do all its work, as is now done in BFD. Contrary to previous versions, the loop is now launched and cleaned by the nest/proto.c code, allowing for a protocol to just request its own loop by setting the loop's lock order in config higher than the_bird. It is not supported nor checked if any protocol changed the requested lock order in reconfigure. No protocol should do it at all. --- lib/lists.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'lib/lists.h') diff --git a/lib/lists.h b/lib/lists.h index 64b4a981..dc49ec8a 100644 --- a/lib/lists.h +++ b/lib/lists.h @@ -68,6 +68,18 @@ typedef union list { /* In fact two overlayed nodes */ #define EMPTY_LIST(list) (!(list).head->next) +static inline _Bool +enlisted(node *n) +{ + switch ((!!n->next) + (!!n->prev)) + { + case 0: return 0; + case 2: return 1; + case 1: bug("Garbled event list node"); + } + + bug("Maths is broken.
