2010-08-09bgpd: fix handling of AS path dataChris Hall
* bgpd/bgp_aspath.c * assegments_parse(): add handling of AS4_PATH input, update bounds checks, add check for AS segment type * aspath_parse(): add handling of AS4_PATH input, expect assegments_parse() to do length checking * aspath_empty(): update for the new function prototype * bgpd/bgp_aspath.h: ditto * tests/aspath_test.c: ditto * bgpd/bgp_attr.c * bgp_attr_aspath(): add handling of AS4_PATH input, update flags checks, change returned type * bgp_attr_as4_path(): discard, superseded by bgp_attr_aspath() * bgp_attr_parse(): update respectively
2009-08-13all: check return value from daemon() callStephen Hemminger
* */*main.c: (main) Current versions of Gcc warn if the return value for daemon() is not checked. So add a simple test and exit on failure.
2009-06-25Add test for Internet checksum.Joakim Tjernlund
Add 2 impl. of the Internet Checksum. One new optimized nad one form RFC 1071. Turns out that the current Quagga in_cksum() is buggy. On Big Endian routers it miscalculates odd sized buffers.
2008-11-16[lib] Switch Fletcher checksum back to old ospfd versionPaul Jakma
* lib/checksum.c: (fletcher_checksum) Switch the second phase of the checksum back to the old ospfd logic. The isisd-derived version: a) is very hard to follow b) had some kind of subtle bug that caused it be wrong when c0=0 and c1=254 (potentially fixable by doing the mods before adjusting x and y) Additionally: - explicitely cast expressions using non-internal variables to int, to ensure the result is signed. - defensively change the length argument to 'size_t', to ensure the code works with that argument being unsigned.. Thanks to Joakim Tjernlund for the investigative work into this bug. * tests/test-checksum.c: new file to exercise the checksum code.

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.

2007-10-14[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[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.
2007-08-08[tests] Add bgp_capability_test.c, should have been part of earlier commitPaul Jakma
2007-08-06[bgpd] cleanup, compact and consolidate capability parsing codePaul Jakma
2007-07-26 Paul Jakma <paul.jakma@sun.com> * (general) Clean up and compact capability parsing slightly. Consolidate validation of length and logging of generic TLV, and memcpy of capability data, thus removing such from cap specifc code (not always present or correct). * bgp_open.h: Add structures for the generic capability TLV header and for the data formats of the various specific capabilities we support. Hence remove the badly named, or else misdefined, struct capability. * bgp_open.c: (bgp_capability_vty_out) Use struct capability_mp_data. Do the length checks *before* memcpy()'ing based on that length (stored capability - should have been validated anyway on input, but..). (bgp_afi_safi_valid_indices) new function to validate (afi,safi) which is about to be used as index into arrays, consolidates several instances of same, at least one of which appeared to be incomplete.. (bgp_capability_mp) Much condensed. (bgp_capability_orf_entry) New, process one ORF entry (bgp_capability_orf) Condensed. Fixed to process all ORF entries. (bgp_capability_restart) Condensed, and fixed to use a cap-specific type, rather than abusing capability_mp. (struct message capcode_str) added to aid generic logging. (size_t cap_minsizes[]) added to aid generic validation of capability length field. (bgp_capability_parse) Generic logging and validation of TLV consolidated here. Code compacted as much as possible. * bgp_packet.c: (bgp_open_receive) Capability parsers now use streams, so no more need here to manually fudge the input stream getp. (bgp_capability_msg_parse) use struct capability_mp_data. Validate lengths /before/ memcpy. Use bgp_afi_safi_valid_indices. (bgp_capability_receive) Exported for use by test harness. * bgp_vty.c: (bgp_show_summary) fix conversion warning (bgp_show_peer) ditto * bgp_debug.h: Fix storage 'extern' after type 'const'. * lib/log.c: (mes_lookup) warning about code not being in same-number array slot should be debug, not warning. E.g. BGP has several discontigious number spaces, allocating from different parts of a space is not uncommon (e.g. IANA assigned versus vendor-assigned code points in some number space).

2006-08-06[bgpd] aspath_loop_check was broken, fix it and the aspath unit test code.Paul Jakma
2006-08-06 Paul Jakma <paul.jakma@sun.com> * bgp_aspath.c: (aspath_loop_check) Fix the typo-bug which essentially had disabled this check. Problem reported by Bartek Kania <mrbk@gnarf.org> in [quagga-users 7388]. * aspath_test.c: (validate) Fix the sense of the aspath_loop_check, which was the wrong way around and had actually been testing for aspath_loop_check to be buggy.
