* buffer.h: Fix comment on buffer_getstr to reflect that it now
uses XMALLOC.
* buffer.c: (buffer_getstr) Use XMALLOC(MTYPE_TMP) instead of malloc.
* filter.c: (access_list_remark,ipv6_access_list_remark) Use
argv_concat instead of buffer_getstr.
* if.c: (interface_desc) Use argv_concat instead of buffer_getstr.
* plist.c: (ip_prefix_list_description,ipv6_prefix_list_description)
Use argv_concat instead of buffer_getstr.
* bgp_filter.c: (ip_as_path,no_ip_as_path) Use argv_concat instead
of buffer_getstr.
* bgp_route.c: (bgp_show_regexp) Fix memory leak: need to free string
returned by buffer_getstr.
(bgp_show_community) Must use XFREE instead of free on string
returned by buffer_getstr.
* bgp_routemap.c: (set_community) Must use XFREE instead of free
on string returned by buffer_getstr.
* bgp_vty.c: (neighbor_description) Use argv_concat instead of
buffer_getstr.

if old one is flaged as BGP_INFO_ATTR_CHANGED.

configured or not. Being not configured is even better reason to
do it.

* *.c: Change level of debug messages to LOG_DEBUG.
|
|
* vty.h: Remove fields in struct vty that were related to VTY_CONTINUE
capabilities (that were used only in bgpd/bgp_route.c and are now
removed). Also remove some other fields that were not being
used at all.
* vty.c: (vty_execute) Do not test for obsolete status values VTY_START
and VTY_CONTINUE.
(vty_read) Remove calls to vty->output_func since that was part
of the VTY_CONTINUE infrastructure that has been removed.
(vty_flush) Remove code to support VTY_START and VTY_CONTINUE.
(vty_close) Remove code to cancel vty->t_output thread, since that
thread was never actually used.
* bgp_route.c: Remove all code related to VTY_CONTINUE; this feature
is deprecated because the output did not represent a single point
in time. All output needs to be generated inline and buffered
by the library code.
(route_vty_out,route_vty_out_tag,damp_route_vty_out,
flap_route_vty_out) Remove code to count number of lines of output,
since this was only useful for VTY_CONTINUE behavior.
(bgp_show_callback) Removed.
(bgp_show_table) Remove hooks for VTY_CONTINUE callback support.
As a result, there's a new output_arg argument to this function.
Make function static.
(bgp_show) Make function static and add a new output_arg argument.
Change all functions that call bgp_show or bgp_show_table to
pass the new output_arg argument (that used to be passed inside
vty->output_arg).
* bgp_mplsvpn.c: Remove declarations of functions defined in
bgp_route.c; these declarations belong in bgp_route.h.
* bgp_route.h: Declare 3 global functions used in both bgp_route.c
and in bgp_mplsvpn.c.
|
|
* (global) more const'ification and fixups of types to clean up code.
* bgp_mplsvpn.{c,h}: (str2tag) fix abuse. Still not perfect,
should use something like the VTY_GET_INTEGER macro, but without
the vty_out bits..
* bgp_routemap.c: (set_aggregator_as) use VTY_GET_INTEGER_RANGE
(no_set_aggregator_as) ditto.
* bgpd.c: (peer_uptime) fix unlikely bug, where no buffer is
returned, add comments about troublesome return value.

(at Technical University of Madrid as part of Euro6ix Project)
Enhanced Route Server functionality and Route-Maps:
* bgpd/bgpd.h: Modified 'struct peer' and 'struct bgp_filter' to
support rs-clients. A 'struct bgp_table *rib' has been added to the
first (to mantain a separated RIB for each rs-client) and two new
route-maps have been added to the last (for import/export policies).
Added the following #defines: RMAP_{IN|OUT|IMPORT|EXPORT|MAX},
PEER_RMAP_TYPE_{IMPORT|EXPORT} and BGP_CLEAR_SOFT_RSCLIENT.
* bgpd/bgpd.c: Modified the functions that create/delete/etc peers in
order to consider the new fields included in 'struct peer' for
supporting rs-clients, i.e. the import/export route-maps and the
'struct bgp_table'.
* bgpd/bgp_route.{ch}: Modified several functions related with
receiving/sending announces in order to support the new Route Server
capabilities.
Function 'bgp_process' has been reorganized, creating an auxiliar
function for best path selection ('bgp_best_selection').
Modified 'bgp_show' and 'bgp_show_route' for displaying information
about any RIB (and not only the main bgp RIB).
Added commands for displaying information about RS-clients RIBs:
'show bgp rsclient (A.B.C.D|X:X::X:X)', 'show bgp rsclient
(A.B.C.D|X:X::X:X) X:X::X:X/M', etc
* bgpd/bgp_table.{ch}: The structure 'struct bgp_table' now has two
new fields: type (which can take the values BGP_TABLE_{MAIN|RSCLIENT})
and 'void *owner' which points to 'struct bgp' or 'struct peer' which
owns the table.
When creating a new bgp_table by default 'type=BGP_TABLE_MAIN' is set.
* bgpd/bgp_vty.c: The commands 'neighbor ... route-server-client' and
'no neighbor ... route-server-client' now not only set/unset the flag
PEER_FLAG_RSERVER_CLIENT, but they create/destroy the 'struct
bgp_table' of the peer. Special actions are taken for peer_groups.
Command 'neighbor ... route-map WORD (in|out)' now also supports two
new kinds of route-map: 'import' and 'export'.
Added commands 'clear bgp * rsclient', etc. These commands allow a new
kind of soft_reconfig which affects only the RIB of the specified
RS-client.
Added commands 'show bgp rsclient summary', etc which display a
summary of the rs-clients configured for the corresponding address
family.
* bgpd/bgp_routemap.c: A new match statement is available,
'match peer (A.B.C.D|X:X::X:X)'. This statement can only be used in
import/export route-maps, and it matches when the peer who announces
(when used in an import route-map) or is going to receive (when used
in an export route-map) the route is the same than the one specified
in the statement.
For peer-groups the statement matches if the specified peer is member
of the peer-group.
A special version of the command, 'match peer local', matches with
routes originated by the Route Server (defined with 'network ...',
redistributed routes and default-originate).
* lib/routemap.{ch}: Added a new clause 'call NAME' for use in
route-maps. It jumps into the specified route-map and when it returns
the first route-map ends if the called RM returns DENY_MATCH, or
continues in other case.

* bgp_packet.c: (bgp_collision_detect) Send NOTIFY on new socket
if that is connection we're closing.
(bgp_read) invalid marker check applies to KEEPALIVE too.
* bgp_route.c: Ignore multicast NRLI, dont send NOTIFY.

* bgpd/bgp_route.c: Delete some extraneous whitespace. Credit to
