2008-07-01[zebra] Make BSD link-state deal more gracefully with GIFMEDIA ioctl errorPaul Jakma
2008-07-01 Paul Jakma <paul.jakma@sun.com> * 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.

2008-02-28[lib] Fix the struct message LOOKUP function to be more robustPaul Jakma
2008-02-28 Paul Jakma <paul.jakma@sun.com> * 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[lib/linklist] Enforce "nodes must have data" invariant more rigorouslyPaul Jakma
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.

(flags_free_index) ditto. * isisd.c: (isis_area_create) use flags_initialize (isis_area_destroy) deconfigure circuits when taking down area.
2008-01-29[bgpd] fix crash on startup if compiled IPv4-onlyPaul Jakma
2008-01-29 Jorge Boncompte <jorge@dti2.net> * bgp_network.c: (bgp_socket) IPv4-only version crashes if -l is not used as address will be null.
2008-01-13[solaris] add missing makefile.am dependencyPaul Jakma
2008-01-13 Paul Jakma <paul.jakma@sun.com> * Makefile.am: pkg target should depend on the 'depend.%' files. Crops up now that solaris/ doesn't get descended into by general Quagga build.

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[link-detect] Try to get BSD link-detect to work properly.Andrew J. Schorr
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.
2008-01-08[link-detect] Static interface routes should behave properly with link-detect.Andrew J. Schorr
2008-01-08 Michael Larson <mike@vyatta.com> * 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.
2008-01-08[lib] add mising UL qualifier to numerical constantPaul Jakma
2008-01-08 Pavol Rusnak <prusnak@suse.cz> * memory.c: (mtype_memstr) Fix accidental shift past width of type, constant should have been forced to UL, rather than being left to default to int.
2007-12-22[bgpd] Fix number of DoS security issues, restricted to configured peers.Paul Jakma
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.

2007-11-13[bgpd] small fix for crash if 'listenon' argument is not givenPaul Jakma
2007-11-13 Paul Jakma <paul.jakma@sun.com> * bgp_main.c: Small fix, format string parameters should never be NULL - it's not strictly valid and some libc's don't let you away with.
2007-11-12+ fixed bug #418 (changing address on an existing interface doesn't cause ↵Denis Ovsienko

2007-10-22[ospf6d] Fix removal of defunct ASBR routesPaul Jakma
2007-10-22 Phil Spagnolo <phillip.a.spagnolo@boeing.com> * 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.
2007-10-22[snmp-smux] Fix problems if 'smux peer ...' is issued multiple timesPaul Jakma
2007-10-22 Lorenzo Colitti <lorenzo@colitti.com> * smux.c: (smux_stop) Avoid cancelling a defunct thread pointer (smux_start) Stop smux before trying to start it, possibly again.

2007-10-14[bgpd] Merge AS4 supportPaul Jakma
2007-10-14 Paul Jakma <paul.jakma@sun.com> * 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

2007-09-18 Paul Jakma <paul.jakma@sun.com> * 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.
2007-09-18[bgpd] Fix typo, which prevented advertisement of MP (non-IPv4) prefixesPaul Jakma
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.
