0c3588bf5e Don't crash when the socket gets closed between updates. 
Also, this time not only update `remains', but update it right :)

93d6bf38a6 The bgp_list is gone. Incomming connections are now handled in a much 
more straightforward manner by scanning the active configuration for
matching protocols.

ce1da96ee7 Added commands show route protocol <p>' and show route import <p>' which 
show the routing table as exported to the protocol given resp. as returned
from its import control hook.

To get handling of filtered extended attributes right (even in the old
`show route where <filter>' command), the get_route_info hook gets an
attribute list and all protocol specific rte attributes are contained
there as temporary ones. Updated RIP to do that.

Added ea_append() which joins two ea_list's.

9a220cabbc #ifdef out lots of debugging information. 
The long resource/routing table dump printed upon startup is gone now
and if you wish to see it, just send bird SIGUSR1 or use the `debug'
commands.

2a149b18cc Unused variables in IPv6 code. 2000-05-04 20:38:44 +00:00
Martin Mares
93a786cb03 Removed a lot of unused variables. 
Please try compiling your code with --enable-warnings to see them. (The
unused parameter warnings are usually bogus, the unused variable ones
are very useful, but gcc is unable to control them separately.)

53943a0022 Defined format specifier %M' which behaves as %m', but takes the 
error code as an argument.
