Ondrej Zajicek (work) 86b4e17001 Nest: Fixes bug in missing cleanup during table removal 
When a table is removed during reconfiguration, a reference was not
cleared in the old configuration, which breaks undo.
 2015-11-09 01:01:12 +01:00
Ondrej Zajicek (work) 9b9a7143c4 Conf: Fixes bug in symbol lookup during reconfiguration 
Symbol lookup by cf_find_symbol() not only did the lookup but also added
new void symbols allocated from cfg_mem linpool, which gets broken when
lookups are done outside of config parsing, which may lead to crashes
during reconfiguration.

The patch separates lookup-only cf_find_symbol() and config-modifying
cf_get_symbol(), while the later is called only during parsing. Also
new_config and cfg_mem global variables are NULLed outside of parsing.
 2015-11-09 00:42:02 +01:00
Ondrej Zajicek (work) fe9f1a6ded Initial commit on integrated BIRD 
New data types net_addr and variants (in lib/net.h) describing
network addresses (prefix/pxlen). Modifications of FIB structures
to handle these data types and changing everything to use these
data types instead of prefix/pxlen pairs where possible.

The commit is WiP, some protocols are not yet updated (BGP, Kernel),
and the code contains some temporary scaffolding.

Comments are welcome.

Ondrej Zajicek 86f567e13c Fix minor issue in pipe route propagation 
In some circumstances during reconfiguration, routes propagated by pipes
to other tables may hang there even after the primary routes are removed.

There is already a workaround for this issue in the code which removes
these stale routes by flush process when source protocols are shut down.

This patch is a cleaner fix and allows to simplify the flush process

Ondrej Zajicek f92e6ab364 Changes order of iface/addr/neigh event hooks. 
Now the order is:

Up   -> iface, addr, neigh
Down -> neigh, addr, iface

It fixes the case when an iface appears, related static routes are
activated and exported to OSPF before the iface notification and
therefore forwarding addresses are not encoded in generated external
LSAs.

When route was propagated to another rtable through a pipe and then the

updates are filtered, then the source protocol shutdown didn't clean up
the route in the second rtable which caused stale routes and potential
crashes.
