bgp_interface_down() and bgp_exit() both proceed to delete the address
from bgpd's interface representation, so the second call gets a NULL
result from the hash lookup and subsequently crashes.

Incorporate a patch by Svetozar Mihailov which implements
default-originate route-maps to behave as expected, i.e. allowing
the default route to be advertised conditionally, depending on a
criterion given by the route-map.
I am aware that the performance attributes of the following implementation
are far from optimal. However, this affects only code paths belonging to
a feature that is broken without this patch, therefore, it seems reasonable
to me to have this in the mainline for now.

peer_sort() it's called so much as to be annoying. In the assumption
that the 'sort' of the peer doesn't change during an established session,
I have changed all calls to peer_sort() in the 'fast-path' to only check
the 'sort'. All the calls from the vty and such still recalculate the sort
and store it in the peer.
There's a lot of other calls to peer_sort() that could be changed but some
maube tricky, someone more knowledgeable may try to reduce them.
This hits peer_sort() from 5th out of the stadium^H^H list on a full
internet table loading profiling session.

This function scores 2nd, profiling a full internet table load. It's called
for every prefix received.
Instead of looping in the interface lists comparing addresses use a hash
to mantain them.
* bgpd.c: Init the own address hash.
* bgp_nexthop.c: Introduce methods to maintain an own address hash.
(bgp_connected_add) add addresses to the hash.
(bgp_connected_delete) delete addresses from the hash.
(bgp_nexthop_self) lookup addresses in the hash. Removed the unused afi_t
parameter.
* bgp_route.c: (bgp_update_main) Micro-optimization, rearranged condition to
not lookup the hash for bogus nexthops (0.0.0.0 or a class D/E address)

* bgp_nexthop.c: The nexthop lookup cache has to return success for queried
nexthops if bgpd isn't connected to zebra, or else BGP without zebra doesn't
work.
|
|
* bgp_nexthop.c (show_ip_bgp_scan_tables): access proper structure field
in AF_INET6 case, handle ifindex NH type properly
|
|
bgp_nexthop_onlink(): zlookup is not used here at all
bgp_nexthop_lookup_ipv6(): rely on the detection performed by "query"
function (this also changes the fallback value to 0), reorder if-block
bgp_nexthop_lookup(): idem
|
|
* bgp_nexthop.c: (show_ip_bgp_scan) transform into
show_ip_bgp_scan_tables(), which uses inet_ntop() and can dump
nexthops on request; (show_ip_bgp_scan_detail_cmd) new function
|
|
bgp_nexthop_lookup_ipv6(): declare variables where they are actually
used, drop no-op initialization (the field is already 0)
bgp_nexthop_lookup(): ditto
bgp_nexthop_check_ebgp(): rename to bgp_nexthop_onlink()
bgp_nexthop_cache_changed(): rename to bgp_nexthop_cache_different()
|

All daemons modified to support custom path to zserv
socket.
lib: generalize a zclient connection
zclient_socket_connect added. zclient_socket and
zclient_socket_un were hidden under static expression.
"zclient_serv_path_set" modified.
|
|
* bgpd: Connected table locks were being locked but not unlocked, such that
eventually a lock would exceed 2^31 and become negative, thus triggering
an assert later on.
* bgp_main.c: (bgp_exit) delete connected elements along with ifp's.
* bgp_nexthop.c: (bgp_nexthop_lookup{,_ipv6}) add missing unlocks
(bgp_multiaccess_check_v4) ditto
(bgp_connected_{add,delete}) Use a distinct memtype for bgp_connected_ref.
(bgp_scan_finish) reset the nexthop cache to clean it up when bgpd exits
* bgp_route.c: fix missing bgp_node unlocks
* lib/memtype.c: (memory_list_bgp) add MTYPE_BGP_CONN
* testing: has been tested for almost 2 months now.

I've spent the last several weeks working on stability fixes to bgpd.
These patches fix all of the numerous crashes, assertion failures, memory
leaks and memory stomping I could find. Valgrind was used extensively.
Added new function bgp_exit() to help catch problems. If "debug bgp" is
configured and bgpd exits with status of 0, statistics on remaining
lib/memory.c allocations are printed to stderr. It is my hope that other
developers will use this to stay on top of memory issues.
Example questionable exit:
bgpd: memstats: Current memory utilization in module LIB:
bgpd: memstats: Link List : 6
bgpd: memstats: Link Node : 5
bgpd: memstats: Hash : 8
bgpd: memstats: Hash Bucket : 2
bgpd: memstats: Hash Index : 8
bgpd: memstats: Work queue : 3
bgpd: memstats: Work queue item : 2
bgpd: memstats: Work queue name string : 3
bgpd: memstats: Current memory utilization in module BGP:
bgpd: memstats: BGP instance : 1
bgpd: memstats: BGP peer : 1
bgpd: memstats: BGP peer hostname : 1
bgpd: memstats: BGP attribute : 1
bgpd: memstats: BGP extra attributes : 1
bgpd: memstats: BGP aspath : 1
bgpd: memstats: BGP aspath str : 1
bgpd: memstats: BGP table : 24
bgpd: memstats: BGP node : 1
bgpd: memstats: BGP route : 1
bgpd: memstats: BGP synchronise : 8
bgpd: memstats: BGP Process queue : 1
bgpd: memstats: BGP node clear queue : 1
bgpd: memstats: NOTE: If configuration exists, utilization may be expected.
Example clean exit:
bgpd: memstats: No remaining tracked memory utilization.
This patch fixes bug #397: "Invalid free in bgp_announce_check()".
This patch fixes bug #492: "SIGBUS in bgpd/bgp_route.c:
bgp_clear_route_node()".
My apologies for not separating out these changes into individual patches.
The complexity of doing so boggled what is left of my brain. I hope this
is all still useful to the community.
This code has been production tested, in non-route-server-client mode, on
a linux 32-bit box and a 64-bit box.
Release/reset functions, used by bgp_exit(), added to:
bgpd/bgp_attr.c,h
bgpd/bgp_community.c,h
bgpd/bgp_dump.c,h
bgpd/bgp_ecommunity.c,h
bgpd/bgp_filter.c,h
bgpd/bgp_nexthop.c,h
bgpd/bgp_route.c,h
lib/routemap.c,h
File by file analysis:
* bgpd/bgp_aspath.c: Prevent re-use of ashash after it is released.
* bgpd/bgp_attr.c: #if removed uncalled cluster_dup().
* bgpd/bgp_clist.c,h: Allow community_list_terminate() to be called from
bgp_exit().
* bgpd/bgp_filter.c: Fix aslist->name use without allocation check, and
also fix memory leak.
* bgpd/bgp_main.c: Created bgp_exit() exit routine. This function frees
allocations made as part of bgpd initialization and, to some extent,
configuration. If "debug bgp" is configured, memory stats are printed
as described above.
* bgpd/bgp_nexthop.c: zclient_new() already allocates stream for
ibuf/obuf, so bgp_scan_init() shouldn't do it too. Also, made it so
zlookup is global so bgp_exit() can use it.
* bgpd/bgp_packet.c: bgp_capability_msg_parse() call to bgp_clear_route()
adjusted to use new BGP_CLEAR_ROUTE_NORMAL flag.
* bgpd/bgp_route.h: Correct reference counter "lock" to be signed.
bgp_clear_route() now accepts a bgp_clear_route_type of either
BGP_CLEAR_ROUTE_NORMAL or BGP_CLEAR_ROUTE_MY_RSCLIENT.
* bgpd/bgp_route.c:
- bgp_process_rsclient(): attr was being zero'ed and then
bgp_attr_extra_free() was being called with it, even though it was
never filled with valid data.
- bgp_process_rsclient(): Make sure rsclient->group is not NULL before
use.
- bgp_processq_del(): Add call to bgp_table_unlock().
- bgp_process(): Add call to bgp_table_lock().
- bgp_update_rsclient(): memset clearing of new_attr not needed since
declarationw with "= { 0 }" does it. memset was already commented
out.
- bgp_update_rsclient(): Fix screwed up misleading indentation.
- bgp_withdraw_rsclient(): Fix screwed up misleading indentation.
- bgp_clear_route_node(): Support BGP_CLEAR_ROUTE_MY_RSCLIENT.
- bgp_clear_node_queue_del(): Add call to bgp_table_unlock() and also
free struct bgp_clear_node_queue used for work item.
- bgp_clear_node_complete(): Do peer_unlock() after BGP_EVENT_ADD() in
case peer is released by peer_unlock() call.
- bgp_clear_route_table(): Support BGP_CLEAR_ROUTE_MY_RSCLIENT. Use
struct bgp_clear_node_queue to supply data to worker. Add call to
bgp_table_lock().
- bgp_clear_route(): Add support for BGP_CLEAR_ROUTE_NORMAL or
BGP_CLEAR_ROUTE_MY_RSCLIENT.
- bgp_clear_route_all(): Use BGP_CLEAR_ROUTE_NORMAL.
Bug 397 fixes:
- bgp_default_originate()
- bgp_announce_table()
* bgpd/bgp_table.h:
- struct bgp_table: Added reference count. Changed type of owner to be
"struct peer *" rather than "void *".
- struct bgp_node: Correct reference counter "lock" to be signed.
* bgpd/bgp_table.c:
- Added bgp_table reference counting.
- bgp_table_free(): Fixed cleanup code. Call peer_unlock() on owner if
set.
- bgp_unlock_node(): Added assertion.
- bgp_node_get(): Added call to bgp_lock_node() to code path that it was
missing from.
* bgpd/bgp_vty.c:
- peer_rsclient_set_vty(): Call peer_lock() as part of peer assignment
to owner. Handle failure gracefully.
- peer_rsclient_unset_vty(): Add call to bgp_clear_route() with
BGP_CLEAR_ROUTE_MY_RSCLIENT purpose.
* bgpd/bgp_zebra.c: Made it so zclient is global so bgp_exit() can use it.
* bgpd/bgpd.c:
- peer_lock(): Allow to be called when status is "Deleted".
- peer_deactivate(): Supply BGP_CLEAR_ROUTE_NORMAL purpose to
bgp_clear_route() call.
- peer_delete(): Common variable listnode pn. Fix bug in which rsclient
was only dealt with if not part of a peer group. Call
bgp_clear_route() for rsclient, if appropriate, and do so with
BGP_CLEAR_ROUTE_MY_RSCLIENT purpose.
- peer_group_get(): Use XSTRDUP() instead of strdup() for conf->host.
- peer_group_bind(): Call bgp_clear_route() for rsclient, and do so with
BGP_CLEAR_ROUTE_MY_RSCLIENT purpose.
- bgp_create(): Use XSTRDUP() instead of strdup() for peer_self->host.
- bgp_delete(): Delete peers before groups, rather than after. And then
rather than deleting rsclients, verify that there are none at this
point.
- bgp_unlock(): Add assertion.
- bgp_free(): Call bgp_table_finish() rather than doing XFREE() itself.
* lib/command.c,h: Compiler warning fixes. Add cmd_terminate(). Fixed
massive leak in install_element() in which cmd_make_descvec() was being
called more than once for the same cmd->strvec/string/doc.
* lib/log.c: Make closezlog() check fp before calling fclose().
* lib/memory.c: Catch when alloc count goes negative by using signed
counts. Correct #endif comment. Add log_memstats_stderr().
* lib/memory.h: Add log_memstats_stderr().
* lib/thread.c: thread->funcname was being accessed in thread_call() after
it had been freed. Rearranged things so that thread_call() frees
funcname. Also made it so thread_master_free() cleans up cpu_record.
* lib/vty.c,h: Use global command_cr. Add vty_terminate().
* lib/zclient.c,h: Re-enable zclient_free().

Use Ansi-C prototypes rather than old K&R method of declaring
function without arguments

* lib/command.h: Add a RESTRICTED_NODE, intended for use with
anonymous, 'no login' vtys, to provide a subset of 'view' mode
commands.
* lib/command.c: Add RESTRICTED_NODE bits, nothing special, just
following VIEW_NODE.
* lib/vty.c: (vty_auth) enable authentication should fall back to
restricted/view node as appropriate.
(vty_create) init vty's to restricted/view node as appropriate,
for the 'no login' case.
(vty_{no_,}restricted_mode_cmd) config commands to enable
'anonymous restricted' in vty configuration.
(vty_config_write) 'anonymous restricted' config.
(vty_init) Install some commands to restricted mode, and the
'anonymous restricted' config commands into VTY_NODE.
* bgpd/*.c: Install some of the safe(r) BGP commands into
'restricted mode', i.e. lookup commands of non-sensitive data.
Useful with looking-glass route-servers.

2006-12-12 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* if.h: (struct connected) Add new ZEBRA_IFA_PEER flag indicating
whether a peer address has been configured. Comment now shows
the new interpretation of the destination addr: if ZEBRA_IFA_PEER
is set, then it must contain the destination address, otherwise
it may contain the broadcast address or be NULL.
(CONNECTED_DEST_HOST,CONNECTED_POINTOPOINT_HOST) Remove obsolete
macros that were specific to IPv4 and not fully general.
(CONNECTED_PEER) New macro to check ZEBRA_IFA_PEER flag.
(CONNECTED_PREFIX) New macro giving the prefix to insert into
the RIB: if CONNECTED_PEER, then use the destination (peer) address,
else use the address field.
(CONNECTED_ID) New macro to come up with an identifying address
for the struct connected.
* if.c: (if_lookup_address, connected_lookup_address) Streamline
logic with new CONNECTED_PREFIX macro.
* prefix.h: (PREFIX_COPY_IPV4, PREFIX_COPY_IPV6) New macros
for better performance than the general prefix_copy function.
* zclient.c: (zebra_interface_address_read) For non-null destination
addresses, set prefixlen to equal the address prefixlen. This
is needed to get the new CONNECTED_PREFIX macro to work properly.
* connected.c: (connected_up_ipv4, connected_down_ipv4,
connected_up_ipv6, connected_down_ipv6) Simplify logic using the
new CONNECTED_PREFIX macro.
(connected_add_ipv4) Set prefixlen in destination addresses (required
by the CONNECTED_PREFIX macro). Use CONNECTED_PEER macro instead
of testing for IFF_POINTOPOINT. Delete invalid warning message.
Warn about cases where the ZEBRA_IFA_PEER is set but no
destination address has been supplied (and turn off the flag).
(connected_add_ipv6) Add new flags argument so callers may set
the ZEBRA_IFA_PEER flag. If peer/broadcast address satisfies
IN6_IS_ADDR_UNSPECIFIED, then reject it with a warning.
Set prefixlen in destination address so CONNECTED_PREFIX will work.
* connected.h: (connected_add_ipv6) Add new flags argument so
callers may set the ZEBRA_IFA_PEER flag.
* interface.c: (connected_dump_vty) Use CONNECTED_PEER macro
to decide whether the destination address is a peer or broadcast
address (instead of checking IFF_BROADCAST and IFF_POINTOPOINT).
* if_ioctl.c: (if_getaddrs) Instead of setting a peer address
only when the IFF_POINTOPOINT is set, we now accept a peer
address whenever it is available and not the same as the local
address. Otherwise (no peer address assigned), we check
for a broadcast address (regardless of the IFF_BROADCAST flag).
And must now pass a flags value of ZEBRA_IFA_PEER to
connected_add_ipv4 when a peer address is assigned.
The same new logic is used with the IPv6 code as well (and we
pass the new flags argument to connected_add_ipv6).
(if_get_addr) Do not bother to check IFF_POINTOPOINT: just
issue the SIOCGIFDSTADDR ioctl and see if we get back
a peer address not matching the local address (and set
the ZEBRA_IFA_PEER in that case). If there's no peer address,
try to grab SIOCGIFBRDADDR regardless of whether IFF_BROADCAST is set.
* if_ioctl_solaris.c: (if_get_addr) Just try the SIOCGLIFDSTADDR ioctl
without bothering to check the IFF_POINTOPOINT flag. And if
no peer address was found, just try the SIOCGLIFBRDADDR ioctl
without checking the IFF_BROADCAST flag. Call connected_add_ipv4
and connected_add_ipv6 with appropriate flags.
* if_proc.c: (ifaddr_proc_ipv6) Must pass new flags argument to
connected_add_ipv6.
* kernel_socket.c: (ifam_read) Must pass new flags argument to
connected_add_ipv6.
* rt_netlink.c: (netlink_interface_addr) Copy logic from iproute2
to determine local and possible peer address (so there's no longer
a test for IFF_POINTOPOINT). Set ZEBRA_IFA_PEER flag appropriately.
Pass new flags argument to connected_add_ipv6.
(netlink_address) Test !CONNECTED_PEER instead of if_is_broadcast
to determine whether the connected destination address is a
broadcast address.
* bgp_nexthop.c: (bgp_connected_add, bgp_connected_delete)
Simplify logic by using new CONNECTED_PREFIX macro.
* ospf_interface.c: (ospf_if_is_configured, ospf_if_lookup_by_prefix,
ospf_if_lookup_recv_if) Simplify logic using new CONNECTED_PREFIX
macro.
* ospf_lsa.c: (lsa_link_ptop_set) Using the new CONNECTED_PREFIX
macro, both options collapse into the same code.
* ospf_snmp.c: (ospf_snmp_if_update) Simplify logic using new
CONNECTED_ID macro.
(ospf_snmp_is_if_have_addr) Simplify logic using new CONNECTED_PREFIX
macro.
* ospf_vty.c: (show_ip_ospf_interface_sub) Use new CONNECTED_PEER macro
instead of testing the IFF_POINTOPOINT flag.
* ospfd.c: (ospf_network_match_iface) Use new CONNECTED_PEER macro
instead of testing with if_is_pointopoint. And add commented-out
code to implement alternative (in my opinion) more elegant behavior
that has no special-case treatment for PtP addresses.
(ospf_network_run) Use new CONNECTED_ID macro to simplify logic.
* rip_interface.c: (rip_interface_multicast_set) Use new CONNECTED_ID
macro to simplify logic.
(rip_request_interface_send) Fix minor bug: ipv4_broadcast_addr does
not give a useful result if prefixlen is 32 (we require a peer
address in such cases).
* ripd.c: (rip_update_interface) Fix same bug as above.

2006-09-06 Paul Jakma <paul.jakma@sun.com>
* (general) Squash any and all prefix-count issues by
abstracting route flag changes, and maintaining count as and
when flags are modified (rather than relying on explicit
modifications of count being sprinkled in just the right
places throughout the code).
* bgp_route.c: (bgp_pcount_{dec,inc}rement) removed.
(bgp_pcount_adjust) new, update prefix count as
needed for a given route.
(bgp_info_{uns,s}et_flag) set/unset a BGP_INFO route status
flag, calling previous function when appropriate.
(general) Update all set/unsets of flags to use previous.
Remove pcount_{dec,inc}rement calls.
No need to unset BGP_INFO_VALID in places where
bgp_info_delete is called, it does that anyway.
* bgp_{damp,nexthop}.c: Update to use bgp_info_{un,}set_flag.
* bgp_route.h: Export bgp_info_{un,}set_flag.
Add a 'meta' BGP_INFO flag, BGP_INFO_UNUSEABLE.
Move BGP_INFO_HOLDDOWN macro to here from bgpd.h

2006-02-21 Paul Jakma <paul.jakma@sun.com>
* bgpd.h: move the clear_node_queue to be peer specific.
Add a new peer status flag, PEER_STATUS_CLEARING.
* bgp_table.h: (struct bgp_table) Add fields to record afi,
safi of the table.
(bgp_table_init) Take afi and safi to create table for.
* bgp_table.c: (bgp_table_init) record the afi and safi.
* bgp_nexthop.c: Update all calls to bgp_table_init.
* bgp_vty.c: ditto.
* bgpd.c: ditto.
* bgp_fsm.c: (bgp_timer_set) dont bring up a session which is
clearing.
* bgp_route.c: (general) Update all bgp_table_init calls.
(bgp_process_{rsclient,main}) clear_node is serialised
via PEER_STATUS_CLEARING and fsm now.
(struct bgp_clear_node_queue) can be removed. struct bgp_node
can be the queue item data directly, as struct peer can be
kept in the new wq global user data and afi/safi can be
retrieved via bgp_node -> bgp_table.
(bgp_clear_route_node) fix to get peer via wq->spec.data,
afi/safi via bgp_node->bgp_table.
(bgp_clear_node_queue_del) no more item data to delete, only
unlock the bgp_node.
(bgp_clear_node_complete) only need to unset CLEARING flag
and unlock struct peer.
(bgp_clear_node_queue_init) queue attaches to struct peer
now. record peer name as queue name.
(bgp_clear_route_table) If queue transitions to active,
serialise clearing by setting PEER_STATUS_CLEARING rather
than plugging process queue, and lock peer while queue
active.
Update to pass only bgp_node as per-queue-item specific data.

2006-01-17 Paul Jakma <paul.jakma@sun.com>
* bgp_nexthop.c: (zlookup_read*) convert to new Zserv format.
(zlookup_query_ipv6) ditto.
(bgp_import_check) ditto.
* isis_zebra.c: (isis_zebra_route_add_ipv4) fix for new
zserv format.

|
* (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.
|
|
* bgp_fsm.h: Add extern qualifier to exported functions
* bgp_nexthop.c: add static to nexthop specific globals
* *.h: Add guard defines
|
|
* (global): Fix up list loops to match changes in lib/linklist,
and some basic auditing of usage.
* configure.ac: define QUAGGA_NO_DEPRECATED_INTERFACES
* HACKING: Add notes about deprecating interfaces and commands.
* lib/linklist.h: Add usage comments.
Rename getdata macro to listgetdata.
Rename nextnode to listnextnode and fix its odd behaviour to be
less dangerous.
Make listgetdata macro assert node is not null, NULL list entries
should be bug condition.
ALL_LIST_ELEMENTS, new macro, forward-referencing macro for use
with for loop, Suggested by Jim Carlson of Sun.
Add ALL_LIST_ELEMENTS_RO for cases which obviously do not need the
"safety" of previous macro.
LISTNODE_ADD and DELETE macros renamed to ATTACH, DETACH, to
distinguish from the similarly named functions, and reflect their
effect better.
Add a QUAGGA_NO_DEPRECATED_INTERFACES define guarded section
with the old defines which were modified above,
for backwards compatibility - guarded to prevent Quagga using it..
* lib/linklist.c: fix up for linklist.h changes.
* ospf6d/ospf6_abr.c: (ospf6_abr_examin_brouter) change to a single
scan of the area list, rather than scanning all areas first for
INTER_ROUTER and then again for INTER_NETWORK. According to
16.2, the scan should be area specific anyway, and further
ospf6d does not seem to implement 16.3 anyway.

* bgpd.[ch], bgp_nexthop.c, bgp_snmp.c: Remove useless bgp_get_master()
function.
* bgp_packet.c: MP AFI_IP update and withdraw parsing.
* bgp_fsm.c: Reset peer synctime in bgp_stop(). bgp_fsm_change_status()
is better place to log about peer status change than bgp_event().
Log in bgp_connect_success().
* bgp_vty.c: Fix typo in comment.
* bgp_attr.c: Better log about unknown attribute.
[merge from GNU Zebra]

* *.c: Change level of debug messages to LOG_DEBUG.
|
|
* bgp_nexthop.c: collapse bgp_connected_ipvX, bgp_nexthop_cache_ipvX
and cache{1,2}.. into arrays of tables and hence collapse
bgp_scan_ipv{4,6} into a single bgp_scan function. Tested, though
a long time ago (and this change was hand-merged).

ripd might need some more testing though.

* zebra/connected.c: revert the 'generic PtP' patch as it causes
far too many problems. People who use FreeSWAN should investigate
native linux ipsec.
