This fixes a reported assert() in 'no neighbor xxx'.
It also fixes other issues found when reviewing and testing that.
Also fixed is a reported segfault caused by prefix lists without explicit
sequence numbers.
Peer State
==========
Tightened up the peer state handling, including:
* shades of pIdle -- depending on some peer flags and the session, if any
* state transitions -- particularly pEstablished -> pIdle or pClearing
* handling if deleting peer and associated session
* handling of PEER_DOWN_XXX -- why peer was last downed
* handling of last NOTIFICATION sent/received
RS Client RIBs
==============
Cleared up places where RS Client RIBs were not disposed of properly when a
peer's afi/safi state changed, in particular:
-- when deactivating an afi/safi
-- when unsetting the rs client state for an afi/safi
-- when binding a peer to a group for an afi/safi
In the past these issues were probably invisible, except for a slight leak of
memory. With the newer code these issues triggered some asserts when closing
down a peer or the entire program.
Program Termination
===================
Now terminates by deleting all peers -- essentially 'no neighbor' for all
peers. Each time a peer is set to be deleted bm->peer_linger_count is
incremented, when the peer finally is deleted, the count is decremented.
So while in program_terminating state, all nexuses continue to run until
the Routing Engine spots that there are no peers left to delete. Then all
nexuses are shut down and the program finally terminates. To do this, when
termination starts a new Routing Engine foreground task is added, which
calls program_terminate_if_all_peers_deleted().
Accept() Status for Session
===========================
The accept() code needs to find the session associated with the incoming IP
address. Then it needs to see if can accept the incoming connection.
It looks up the IP address in the Peer Index (under its Mutex).
Previously: the Peer Index entry contained a pointer to the accepting
connection (if any), and the session had a pointer to the Peer Index entry
so that it could set/clear the accept field in that entry.
Now: have removed the accept field in the Peer Index entry, and the pointer
from the session to that entry.
There is now an "accept" flag in the session structure -- so setting/clearing
accept does not have to fiddle with any state to do with the peer. Which
seems cleaner.
To find the session, the accept() code goes via the Peer Index and then via
the peer to find the session. This is done under the Peer Index Mutex. To
support that, the Routing Engine only changes the peer->session pointer under
the same Mutex.
General Changes
===============
1. name changes: peer_lock -> bgp_peer_lock etc.
2. bgp_notify_send -> bgp_peer_down_error

bgp_notify_send_with_data()
bgpd/bgp_peer.c -- changed:
bgp_session_has_established()
bgp_session session()
bgp_session_has_disabled()
to void and to take session, not peer.
- removed lock of session structure in
bgp_session_do_event() -- was holding the lock
for far longer than necessary, particularly
when clearing routes !
- in bgp_session_has_established():
- lock session structure where and only where
required
- tidied up timer handling
- in bgp_session_has_stopped():
- extend IdleHoldTime
- examine notification etc to see why session
came down.
- invoke bgp_peer_down_notify(), which will
start the process of downing the peer.
- in bgp_session_has_disabled():

is done in bgp_peer_down() et all.
- now if session is marked delete_me, then do
that; otherwise, can enable again.

replaced by new mechanism
- in bgp_peer_stop():
- changed to void function and added nsf
parameter.
- sets pClearing state.
- MUST now only be called when pEstablished.
- removed some code to bgp_peer_reset_idle().
So... bgp_peer_stop() brings pEstablished
peer to halt, while bgp_peer_reset_idle()
prepares it for new session.
- now passes nsf to bgp_clear_all_routes(),
which returns flag to say whether task is
complete or whether it continues in
background.
- clearing of NSF_MODE and flags moved to
bgp_peer_reset_idle().
- sets pIdle state if route clearing completed
- renamed peer_nsf_stop() -> bgp_peer_nsf_stop()
- if is pIdle or pClearing and have NSF
routes, then stops timers and clears out
all the NSF routes.
- added bgp_peer_clear_all_stale_routes()

is downed for PEER_DOWN_USER_SHUTDOWN !
- added bgp_peer_reset_idle() -- used when peer
goes pIdle or is about to enable session.
- deleted bgp_peer_timers_stop() -- see
bgp_peer_change_status().
- replaced bgp_peer_clearing_completed()
- if pClearing, sets pIdle and enables if can
- if pDeleting, unlocks peer
- replaced bgp_timer_set() by
bgp_peer_timers_set() -- deals in new peer
states only.
- renamed peer_new() -> bgp_peer_new()
- renamed peer_create() -> bgp_peer_create()
- added setting of PEER_STATUS_REAL_PEER
- changed auto activation to reflect what
actually happens.
- changed bgp_session_init_new() call because
it now sets peer->session.
- sets timers suitable for pIdle. before any
auto enable.
- renamed peer_delete() -> bgp_peer_delete()
- removed call of peer_nsf_stop()
- added bgp_peer_down() with
PEER_DOWN_NEIGHBOR_DELETE -- which does all
the work of flattening an active peer, and
returns it pIdle or pClearing.
- if pClearing, lock the peer so that when
clearing completes, it can unlock it.
- sets pDeleting state, and increments
bm->peer_linger_count.
- tightened procedure for dealing with various
references to peer -- including use of the
PEER_STATUS_REAL_PEER flag.
- tidied up dealing with rsclient RIBs and
shared pointers to group versions of same.
- removed call of bgp_timer_set(), now done
in bgp_peer_change_status().
- now unregisters the peer immediately, so
can register a new one before this one
is completely deleted.
- deletes session if it can.
- moved peer_lock() & peer_unlock() from bgpd.c
and renamed bgp_peer_lock() & bgp_peer_unlock()
- renamed peer_free() bgp_peer_free() and made
static.
- peer must be pDeleting -- so have been
through bgp_peer_delete()
- peer->session must be NULL
- decrements bm->peer_linger_count
- deleted peer->clear_node_queue handling
- deleted bgp_session_free() -- that's done
in bgp_peer_delete() or elsewhere.
- unlocked bgp at end
- assert peer->session == NULL, to be sure
- set peer->lock == -54321
- in bgp_peer_enable():
- recast as switch() on peer state
- added bgp_peer_reset)idle() before enabling
the session.
- renamed bgp_peer_disable() -> bgp_peer_down()
- takes PEER_DOWN_XXX argument, which drives
what notification is sent, and sets the
peer->last_reset status. A small number of
PEER_DOWN_XXX are special.
- removed the IdleHoldTimer stuff.
- copies outbound notification to session.
- for PEER_DOWN_NSF_CLOSE_SESSION, keep non-
stale routes.
- for PEER_DOWN_USER_SHUTDOWN, do
bgp_peer_shutdown()
- after disabling any session and doing any
shutdown, proceed as per peer->status:
pIdle -- flush stale routes
bgp_peer_enable()
pEstablished -- bgp_peer_stop()
pClearing -- flush stale routes
- added bgp_peer_down_notify().
- added bgp_peer_down_error(), which replaces
bgp_notify_send().
- added bgp_peer_down_error_with_data(), which
replaces bgp_notify_send_with_data()
The "down_error" functions calculate the
appropriate PEER_DOWN_XXX value, and call
bgp_peer_down_notify().
- added bgp_peer_map_peer_down(), to map
PEER_DOWN_XXX to a notification message.
- added bgp_peer_map_notification, to map
notification message to a PEER_DOWN_XXX.
- renamed peer_change_status() ->
bgp_peer_change_status()

In the introduction of the BGP Engine the logging of NOTIFICATION
messages fell by the wayside. This change reinstates that
logging.
This change also turns off the Memory Tracker, unless QDEBUG
is defined.

bgpd/bgp_advertise.c
bgpd/bgp_advertise.h
The adj_in and adj_out objects are now put on a list based
on the peer to whom the route belongs.
The adj_in and adj_out objects also now point to the bgp_node
which they are routes for.
This substantially reduces the work needed to shut down a peer.
bgpd/bgp_damp.c
Changes to adj_in and adj_out forced small change to macros
used in bgp_damp.c to manage its lists.
bgpd/bgp_debug.c
Replaced direct access to vty->node by the required vty_get_node().
bgpd/bgp_dump.c
Changes to the names of fields in bgp_info structures.
bgpd/bgp_engine.h
Modified the debug and trace functions.
bgpd/bgp_fsm.c
Make use of sockunion2str() consistent with common usage.
Improved some documentation.
bgpd/bgp_main.c
Use the newly extended qpn_add_hook_function() facility.
bgpd/bgp_mplsvpn.c
Changes to the names of fields in bgp_info structures.
bgpd/bgp_msg_read.c
Bug fix: correct handling of capability code length.
Improvement: better casting in calculation of message length.
bgpd/bgp_msg_write.c
Bug fix: correct byte ordering of bgp_id in open message.
bgpd/bgp_network.c
Bug fix: correct handling of incoming connections.
Takes advantage of improvements in sockunion.c.
bgpd/bgp_nexthop.c
Changes to the names of fields in bgp_info structures.
bgpd/bgp_open_state.c
Remove mistaken #include of memtypes.h
bgpd/bgp_packet.c
Improvements to handling of withdrawing routes for peers.
bgpd/bgp_peer.c
Tidying up the state of peers as they are enabled and disabled.
Improvements to handling of withdrawing routes for peers.
bgpd/bgp_peer.h
Adding list bases for lists of routes originated by the peer.
bgpd/bgp_peer_index.c
Bug fix: correct freeing of peer indexes.
bgpd/bgp_route.c
Implement lists of bgp_info based in the owning peer. Adjust
for name changes to bgp_info fields.
Reimplemented all the clearing functions to use the lists of
items that belong to the peer -- rather than searching route
tables for stuff to withdraw.
Changed work queue handling for added/changed routes, so
that queues run through existing items, rather than having
queues of auxiliary items -- lower memory overhead.
bgpd/bgp_route.h
Added fields to bgp_info to allow all bgp_info originated by
each peer to live on lists based in the peer. And changed the
name of existing fields to avoid confusion.
bgpd/bgp_routemap.c
Removing redundant code and fixing a memory leak.
bgpd/bgp_table.h
Based work queue for added/changed routes directly in the
table, rather than having auxiliary structures.
bgpd/bgp_vty.c
Use vty_get_node() and vty_set_node() rather than direct
access to the vty field.
bgpd/bgpd.c
Implement changes to route clearing.
bgpd/bgpd.h
Changes to work queue handling.

Substantial tidy up and document exercise.
Restructured the top level command processing and finding
of descriptions and command completion.
Removal of unpleasant messing around with the insides of
vector structures.
Movement of some command actions to vty.c.
Uses uty.h to pick up the "private" functions from vty.c
et al.
lib/command.h
Moved the "node" values to node_type.h, so that can use an
enum node_type in places where cannot include command.h.
lib/command_queue.c
Updated to cope with the called command changing the node
value.
Improved handling of revoked commands, so the the command
line handler does not get stuck waiting for a command to
complete which has been revoked !
lib/command_queue.h
Improved message format.
lib/if.c
Use vty_set_node().
lib/keychain.c
Use vty_set_node().
new lib/keystroke.c

The handling of mixtures of escapes and Telnet IACs is
tightened up.

Regularises the "stealing" of keystrokes for the "--more--"
output handling... which was a bit hit and miss.
new lib/list_util.c
new lib/list_util.h
New code to implement various forms of linked list,
where the list pointers are embedded in structures.

new lib/node_type.h
As above.
lib/plist.c
Remove vty_puts() which wasn't a good idea.
lib/qlib_init.c
Added qps_init() to first stage and mqueue_finish to
finish.
lib/qpnexus.c
lib/qpnexus.h
More flexible hooks for in_thread_init and in_thread_final.

new lib/vty_cli.h
CLI handling parts of the vty family.
new lib/vty_io.c
new lib/vty_io.h

Finish the wiring required to get bgp_msg_read to process OPEN
messages into the connection's open_state, and be able to check
for correct peer AS, etc.
Removed bugs preventing messages from being written.
Added BGP Id check to collision detection logic.
Removed as many warnings from comilation as possible. Replaced
horrible FIFO kludge in the process. (Introduced the even more
horrible miyagi kludge.)

* bgp_open.c: (bgp_capability_as4) debug printf inline with others.
(peek_for_as4_capability) There's no need to signal failure, as
failure is better dealt with through full capability parser -
just return the AS4, simpler.
* bgp_packet.c: (bgp_open_receive) Update to match
peek_for_as4_capability change.
Allow use of BGP_AS_TRANS by 2b speakers.
Use NOTIFY_OPEN_ERR rather than CEASE for OPEN parsing errors.
(bgp_capability_msg_parse) missing argument to debug print
(bgp_capability_receive) missing return values.
* tests/bgp_capability_test.c: (parse_test) update for changes to
peek_for_as4_capability
2007-07-25 Paul Jakma <paul.jakma@sun.com>
* Remove 2-byte size macros, just make existing macros take
argument to indicate which size to use.
Adjust all users - typically they want '1'.
* bgp_aspath.c: (aspath_has_as4) New, return 1 if there are any
as4's in a path.
(aspath_put) Return the number of bytes actually written, to
fix the bug Juergen noted: Splitting of segments will change
the number of bytes written from that already written to the
AS_PATH header.
(aspath_snmp_pathseg) Pass 2-byte flag to aspath_put. SNMP
is still defined as 2b.
(aspath_aggregate) fix latent bug.
(aspath_reconcile_as4) AS_PATH+NEW_AS_PATH reconciliation
function.
(aspath_key_make) Hash the AS_PATH string, rather than
just taking the addition of assegment ASes as the hash value,
hopefully sligthly more collision resistant.
(bgp_attr_munge_as4_attrs) Collide the NEW_ attributes
together with the OLD 2-byte forms, code Juergen
had in bgp_attr_parse but re-organised a bit.
(bgp_attr_parse) Bunch of code from Juergen moves
to previous function.
(bgp_packet_attribute) Compact significantly by
just /always/ using extended-length attr header.
Fix bug Juergen noted, by using aspath_put's
(new) returned size value for the attr header rather
than the (guesstimate) of aspath_size() - the two could
differ when aspath_put had to split large segments, unlikely
this bug was ever hit in the 'wild'.
(bgp_dump_routes_attr) Always use extended-len and
use aspath_put return for header length. Output 4b ASN
for AS_PATH and AGGREGATOR.
* bgp_ecommunity.c: (ecommunity_{hash_make,cmp}) fix
hash callback declarations to match prototypes.
(ecommunity_gettoken) Updated for ECOMMUNITY_ENCODE_AS4,
complete rewrite of Juergen's changes (no asdot support)
* bgp_open.c: (bgp_capability_as4) New, does what it says
on the tin.
(peek_for_as4_capability) Rewritten to use streams and
bgp_capability_as4.
* bgp_packet.c: (bgp_open_send) minor edit
checked (in the abstract at least) with Juergen.
Changes are to be more accepting, e.g, allow AS_TRANS on
a 2-byte session.
* (general) Update all commands to use CMD_AS_RANGE.
* bgp_vty.c: (bgp_clear) Fix return vals to use CMD_..
Remove stuff replicated by VTY_GET_LONG
(bgp_clear_vty) Return bgp_clear directly to vty.
* tests/aspath_test.c: Exercise 32bit parsing. Test reconcile
function.
* tests/ecommunity_test.c: New, test AS4 ecommunity changes,
positive test only at this time, error cases not tested yet.
2007-07-25 Juergen Kammer <j.kammer@eurodata.de>
* (general) AS4 support.
* bgpd.h: as_t changes to 4-bytes.
* bgp_aspath.h: Add BGP_AS4_MAX and BGP_AS_TRANS defines.
* bgp_aspath.c: AS_VALUE_SIZE becomes 4-byte, AS16_VALUE_SIZE
added for 2-byte.
Add AS16 versions of length calc macros.
(aspath_count_numas) New, count number of ASes.
(aspath_has_as4) New, return 1 if there are any as4's in a
path.
(assegments_parse) Interpret assegment as 4 or 2 byte,
according to how the caller instructs us, with a new
argument.
(aspath_parse) Add use32bit argument to pass to
assegments_parse. Adjust all its callers to pass 1, unless
otherwise noted.
(assegment_data_put) Adjust to be able to write 2 or 4 byte
AS, according to new use32bit argument.
(aspath_put) Adjust to write 2 or 4.
(aspath_gettoken) Use a long for passed in asno.
* bgp_attr.c: (attr_str) Add BGP_ATTR_AS4_PATH and
BGP_ATTR_AS4_AGGREGATOR.
(bgp_attr_aspath) Call aspath_parse with right 2/4 arg, as
determined by received-capability flag.
(bgp_attr_aspath_check) New, code previously in attr_aspath
but moved to new func so it can be run after NEW_AS_PATH
reconciliation.
(bgp_attr_as4_path) New, handle NEW_AS_PATH.
(bgp_attr_aggregator) Adjust to cope with 2/4 byte ASes.
(bgp_attr_as4_aggregator) New, read NEW_AGGREGATOR.
(bgp_attr_parse) Add handoffs to previous parsers for the two
new AS4 NEW_ attributes.
Various checks added for NEW/OLD reconciliation.
(bgp_packet_attribute) Support 2/4 for AS_PATH and
AGGREGATOR, detect when NEW_ attrs need to be sent.
* bgp_debug.{c,h}: Add 'debug bgp as4'.
* bgp_dump.c: MRTv2 support, unconditionally enabled, which
supports AS4. Based on patches from Erik (RIPE?).
* bgp_ecommunity.c: (ecommunity_ecom2str) ECOMMUNITY_ENCODE_AS4
support.
* bgp_open.c: (peek_for_as4_capability) New, peek for AS4
capability prior to full capability parsing, so we know which
ASN to use for struct peer lookup.
(bgp_open_capability) Always send AS4 capability.
* bgp_packet.c: (bgp_open_send) AS4 handling for AS field
(bgp_open_receive) Peek for AS4 capability first, and figure
out which AS to believe.
* bgp_vty.c: (bgp_show_peer) Print AS4 cap
* tests/aspath_test.c: Support asn32 changes, call aspath_parse
with 16 bit.
* vtysh/extract.pl: AS4 compatibility for router bgp ASNUMBER
* vtysh/extract.pl.in: AS4 compatibility for router bgp ASNUMBER
* vtysh/vtysh.c: AS4 compatibility for router bgp ASNUMBER

2006-09-14 Paul Jakma <paul.jakma@sun.com>
* (general) Fix some niggly issues around 'shutdown' and clearing
by adding a Clearing FSM wait-state and a hidden 'Deleted'
FSM state, to allow deleted peers to 'cool off' and hit 0
references. This introduces a slow memory leak of struct peer,
however that's more a testament to the fragility of the
reference counting than a bug in this patch, cleanup of
reference counting to fix this is to follow.
* bgpd.h: Add Clearing, Deleted states and Clearing_Completed
and event.
* bgp_debug.c: (bgp_status_msg[]) Add strings for Clearing and
Deleted.
* bgp_fsm.h: Don't allow timer/event threads to set anything
for Deleted peers.
* bgp_fsm.c: (bgp_timer_set) Add Clearing and Deleted. Deleted
needs to stop everything.
(bgp_stop) Remove explicit fsm_change_status call, the
general framework handles the transition.
(bgp_start) Log a warning if a start is attempted on a peer
that should stay down, trying to start a peer.
(struct .. FSM) Add Clearing_Completed
events, has little influence except when in state
Clearing to signal wait-state can end.
Add Clearing and Deleted states, former is a wait-state,
latter is a placeholder state to allow peers to disappear
quietly once refcounts settle.
(bgp_event) Try reduce verbosity of FSM state-change debug,
changes to same state are not interesting (Established->Established)
Allow NULL action functions in FSM.
* bgp_packet.c: (bgp_write) Use FSM events, rather than trying
to twiddle directly with FSM state behind the back of FSM.
(bgp_write_notify) ditto.
(bgp_read) Remove the vague ACCEPT_PEER peer_unlock, or else
this patch crashes, now it leaks instead.
* bgp_route.c: (bgp_clear_node_complete) Clearing_Completed
event, to end clearing.
(bgp_clear_route) See extensive comments.
* bgpd.c: (peer_free) should only be called while in Deleted,
peer refcounting controls when peer_free is called.
bgp_sync_delete should be here, not in peer_delete.
(peer_delete) Initiate delete.
Transition to Deleted state manually.
When removing peer from indices that provide visibility of it,
take great care to be idempotent wrt the reference counting
of struct peer through those indices.
Use bgp_timer_set, rather than replicating.
Call to bgp_sync_delete isn't appropriate here, sync can be
referenced while shutting down and finishing deletion.
(peer_group_bind) Take care to be idempotent wrt list references
indexing peers.

* (global) The great bgpd extern and static'ification.
* bgp_routemap.c: remove unused ROUTE_MATCH_ASPATH_OLD code
(route_set_metric_compile) fix u_int32_t to ULONG_MAX comparison
warnings.
* bgp_route.h: (bgp_process, bgp_withdraw, bgp_update) export these
used by various files which had their own private declarations,
in the case of mplsvpn - incorrect.
|
| |
|
|
| |
* *.c: Change level of debug messages to LOG_DEBUG.
|
| |
|
|
|
|
|
|
|
|
|

* (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.

Merge of GNU Zebra cvs2svn changesets r799, r800 and r807.
* bgp_dump.c: (bgp_dump_attr) cleanup. return status code. check
attributes present before printing.
* bgp_dump.c: update bgp_dump_attr prototype.
* bgp_packet.c: (bgp_update_receive) init attrstr. check status

* (many) reference <lib/version.h> rather than "version.h",
because version.h is a generated file and not present in the
source tree when using objdir builds.
(committed by gdt)
works fine with normal builds; didn't try objdir
