From 2d14045224f2233aed386eddf155d10a81892c3f Mon Sep 17 00:00:00 2001 From: Martin Mares Date: Wed, 3 Mar 1999 19:49:56 +0000 Subject: Rewrote the kernel syncer. The old layering was horrible. The new kernel syncer is cleanly split between generic UNIX module and OS dependent submodules: - krt.c (the generic part) - krt-iface (low-level functions for interface handling) - krt-scan (low-level functions for routing table scanning) - krt-set (low-level functions for setting of kernel routes) krt-set and krt-iface are common for all BSD-like Unices, krt-scan is heavily system dependent (most Unices require /dev/kmem parsing, Linux uses /proc), Netlink substitues all three modules. We expect each UNIX port supports kernel routing table scanning, kernel interface table scanning, kernel route manipulation and possibly also asynchronous event notifications (new route, interface state change; not implemented yet) and build the KRT protocol on the top of these primitive operations. --- sysdep/unix/krt.Y | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) (limited to 'sysdep/unix/krt.Y') diff --git a/sysdep/unix/krt.Y b/sysdep/unix/krt.Y index 7711f3b..661e505 100644 --- a/sysdep/unix/krt.Y +++ b/sysdep/unix/krt.Y @@ -10,9 +10,11 @@ CF_HDR #include "lib/krt.h" +#define THIS_KRT ((struct krt_config *) this_proto) + CF_DECLS -CF_KEYWORDS(KERNEL) +CF_KEYWORDS(KERNEL, PERSIST, SCAN, TIME, ROUTE, LEARN) CF_GRAMMAR @@ -28,6 +30,17 @@ kern_proto_start: proto_start KERNEL { CF_ADDTO(kern_proto, kern_proto_start '{') CF_ADDTO(kern_proto, kern_proto proto_item ';') +CF_ADDTO(kern_proto, kern_proto kern_item ';') + +kern_item: + PERSIST bool { THIS_KRT->persist = $2; } + | SCAN TIME expr { + /* Scan time of 0 means scan on startup only */ + THIS_KRT->scan_time = $3; + } + | ROUTE SCAN TIME expr { THIS_KRT->route_scan_time = $4; } + | LEARN bool { THIS_KRT->learn = $2; } + ; CF_CODE -- cgit v1.2.3
