* ioctl.c: (if_get_flags) Deal more gracefully with failure
of the BSD link-state SIOCGIFMEDIA ioctl, as some interfaces
apparently don't implement it (e.g. tun).
Also, make BSD link-state checking be conditional on the
'link-detect' interface configuration flag, as it should be.
Fixes bug #465.

* bgp_attr.c: (bgp_mp_reach_parse) Add logging. Tighten length test
to bounds check against the attribute length rather than the
stream length..

* log.c: (mes_lookup) Sowmini Varadhan diagnosed a problem where
this function can cause a NULL dereference, on lookups for unknown
indices, or messages with NULL strings. Can occur, e.g., debug
logging code when processing received messages. Fixed to accept a
pointer to a default string to be used if there is no match.
* log.h: LOOKUP adjusted to match

|
2008-02-28 Paul Jakma <paul.jakma@sun.com>
* linklist.c: This implementation expects that the data pointer not
be null, e.g. listgetdata() asserts this. The list add methods
don't apply the same sanity check.
Noted by Jim Carlson in bug #437.

2008-01-11 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* lib/zebra.h: Revert previous change, no need to include
<net/if_media.h> here.
* zebra/ioctl.c: If HAVE_BSD_LINK_DETECT is defined, include
<net/if_media.h>
(if_get_flags) Remove debug messages about BSD link state.
* zebra/kernel_socket.c: (bsd_linkdetect_translate) If link state
is unknown, we should set the IFF_RUNNING flag.
|
|
2008-01-10 Ingo Flaschberger <if@xip.at>
* configure.ac: Define HAVE_BSD_LINK_DETECT if <net/if_media.h> is
present.
* lib/zebra.h: If HAVE_BSD_LINK_DETECT is defined,
include <net/if_media.h>.
* zebra/ioctl.c: (if_get_flags) If HAVE_BSD_LINK_DETECT, use the
SIOCGIFMEDIA ioctl to ascertain link state.
* zebra/kernel_socket.c: (bsd_linkdetect_translate) New function to
map the ifm_data.ifi_link_state value into the IFF_RUNNING flag.
(ifm_read) Call bsd_linkdetect_translate to fix the IFF_RUNNING
flag before calling if_flags_update.

* zebra_rib.c: (nexthop_active_check) Replace if_is_up with
if_is_operative to solve problems with static interface
routes not behaving properly with link-detect.

2007-12-22 Paul Jakma <paul.jakma@sun.com>
* Fix series of vulnerabilities reported by "Mu Security
Research Team", where bgpd can be made to crash by sending
malformed packets - requires that bgpd be configured with a
session to the peer.
* bgp_attr.c: (bgp_attr_as4_path) aspath_parse may fail, only
set the attribute flag indicating AS4_PATH if we actually managed
to parse one.
(bgp_attr_munge_as4_attrs) Assert was too general, it is possible
to receive AS4_AGGREGATOR before AGGREGATOR.
(bgp_attr_parse) Check that we have actually received the extra
byte of header for Extended-Length attributes.
* bgp_attr.h: Fix BGP_ATTR_MIN_LEN to account for the length byte.
* bgp_open.c: (cap_minsizes) Fix size of CAPABILITY_CODE_RESTART,
incorrect -2 left in place from a development version of as4-path
patch.
* bgp_packet.c: (bgp_route_refresh_receive) ORF length parameter
needs to be properly sanity checked.
* tests/bgp_capability_test.c: Test for empty capabilities.

* ospf6_asbr.c: (ospf6_asbr_lsentry_remove) Remove shortcut
of LSDB search - it's based on assumption non-BEST routes
can't have ASBR routes, which appears to be wrong. Safest to
search.

* NEWS: Note that MRT dumps are now version 2
* (general) Merge in Juergen Kammer's AS4 patch.
2007-09-27 Paul Jakma <paul.jakma@sun.com>
* bgp_aspath.c: (assegment_normalise) remove duplicates from
from sets.
(aspath_reconcile_as4) disregard a broken part of the RFC around
error handling in path reconciliation.
* aspath_test.c: Test dupe-weeding from sets.
Test that reconciliation merges AS_PATH and AS4_PATH where
former is shorter than latter.
2007-09-26 Paul Jakma <paul.jakma@sun.com>
* aspath_test.c: Test AS4_PATH reconcilation where length
of AS_PATH and AS4_PATH is same.
2007-09-25 Paul Jakma <paul.jakma@sun.com>
* bgp_open.c: (peek_for_as4_capability) Fix to work.
* bgp_packet.c: (bgp_open_receive) Fix sanity check of as4.
* tests/bgp_capability_test.c: (general) Extend tests to validate
peek_for_as4_capability.
Add test of full OPEN Option block, with multiple capabilities,
both as a series of Option, and a single option.
Add some crap to beginning of stream, to prevent code depending
on getp == 0.
2007-09-18 Paul Jakma <paul.jakma@sun.com>
* 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

* privs.c: definition of ZCAP_NET_ADMIN on Solaris should
be PRIV_SYS_IP_CONFIG, when that's available. Thus allowing
Quagga to work with in Solaris zones with exclusive IP
instances.

2007-09-17 Paul Jakma <paul.jakma@sun.com>
* bgp_open.c: (bgp_capability_mp) We were setting
afc_nego[safi][safi] rather than afc_nego[afi][safi], thus
failling to announce any non-IPv4 prefixes. Remove the extra,
typo-ed character.
* bgp_capability_test.c: Test that peer's adv_recv and adv_nego get
set correctly for MP capability and given AFI/SAFI.
Colour OK/failed result so it's easier to find them.
