2012-11-05build: check actually-used BSD link state fieldsDoug VanLeuven
ifi_link_state missing in OS X. There could be other *BSD's that haven't implemented it and possibly affects older implementations. The existing HAVE_BSD_LINK_DETECT configure.ac check is only confirming the link state detection using ifmediareq.ifm_status found in <net/if_media.h>. This is the link state detection used in zebra/ioctl.c. Later, *BSD redefined struct if_data in <net/if.h> and included link state detection. This is the method used in zebra/kernel_socket.c Additional test defined in config.ac to test for member struct if_data.ifi_link_state defined in <net/if.h> separate from test for <net/if_media.h> ifmediareq.ifm_status Fixed #ifdef's in zebra/kernel_socket.c to use the new #define No impact on older function calls in zebra/ioctl.c Tested on 64bit OS X 10.7, FreeBSD 9.0 amd64 & i386 (32bit) using gcc & clang.

2012-11-05zebra: kernel_socket: fix overflow in RTA_ADDR & RTA_ATTRDoug VanLeuven
In zebra/kernel_socket.c, copying sockaddr from *_msghdr: There are really 2 different lengths that need to be determined. 1) the length required to point to the next sockaddr in the mesg buffer which might include any required padding and 2) the actual length of the sockaddr data that needs to be copied into the destination field. They may or may not be the same value. Sizeof sockaddr_in6 is 28, which to pad for alignment purposes on 32 bit systems with a long of 4 bytes is evenly divided and requires no padding. On 64 bit systems, with a long of 8 it is padded with 4 extra bytes.So the current RTA_* macros are copying 32 bytes into a 28 byte field on 64 bitsystems, where the field overflow did not occur on the 32 bit systems. Since using sa_len required the use of an #ifdef which couldn't be used directly inside a #define, it made sense to move the copy into the function to allow typdef checking throughout and eliminate the hack to suppress compiler warnings. Fixed declaration of cp in ifm_read after compiler noticed type mismatch.

In OS X 10.7 zebra crashed on invalid execution address. sockaddr padding in *_msghdr is observed to be 4 bytes in 64bit OS X. The ROUNDUP macro assumed alignment on sizeof(long) which allocates 8 bytes on 64bit systems, 4 bytes on 32bit systems which is true for BSD generally. Test for Apple and use sizeof(int) which allocates 4 bytes on 32 & 64bit systems.

2012-11-01bgpd: CVE-2012-1820, DoS in bgp_capability_orf()Denis Ovsienko
An ORF (code 3) capability TLV is defined to contain exactly one AFI/SAFI block. Function bgp_capability_orf(), which parses ORF capability TLV, uses do-while cycle to call its helper function bgp_capability_orf_entry(), which actually processes the AFI/SAFI data block. The call is made at least once and repeated as long as the input buffer has enough data for the next call. The helper function, bgp_capability_orf_entry(), uses "Number of ORFs" field of the provided AFI/SAFI block to verify, if it fits the input buffer. However, the check is made based on the total length of the ORF TLV regardless of the data already consumed by the previous helper function call(s). This way, the check condition is only valid for the first AFI/SAFI block inside an ORF capability TLV. For the subsequent calls of the helper function, if any are made, the check condition may erroneously tell, that the current "Number of ORFs" field fits the buffer boundary, where in fact it does not. This makes it possible to trigger an assertion by feeding an OPEN message with a specially-crafted malformed ORF capability TLV. This commit fixes the vulnerability by making the implementation follow the spec.

2012-10-25ospfd: respect max-metric over configured cost for summary LSAsJR Rivers
ISSUE When max-metric router-lsa administrative is invoked on an ABR created with... area <area> range <addr/mask> the summary LSAs are sent out with 65535 (max-metric) added to the normal cost. When max-metric router-lsa administrative is invoked on an ABR created with... area <area> range <addr/mask> cost <cost> the summary LSAs are sent out with <cost> (the max-metric is ignored). This second behavior effectively incapacitates the max-metric function. PATCH This patch evaluates the state of the router and if it's isolated as a stub router (rfc3137) via `max-metric router-lsa`, we unconditionally uses the value of 0xff0000 when advertising summary LSAs.

2012-10-25ospfd: ABR algorithm not propagating MAXAGE LSAs into areaJR Rivers
When a range (or sub-range) is deleted, the area is notified by propagating a MAXAGE LSA. This LSA stays in the database for a while to both insure propagation as well as in the off chance that it's useful in the near future.

2012-10-25ospfd: blackhole route removal for area rangeJR Rivers
ISSUE When an area range is created in which there the sub-area has routes that are smaller than the range, an ABR creates a blackhole route to cover the range. When the range is removed, the blackhole route is not removed. --A----B----C--- B is an ABR with A in area 1 and C in area 0. If A advertises `10.2.0.0/30` and `10.2.0.4/30` and B is configured with `area 0.0.0.1 range 10.2.0.0/29` a blackhole is created on B (`blackhole 10.2.0.0/29 proto zebra`). When the area/range is removed via the command line, the blackhole remains in existence even though the "range" route is removed from area 0 and the individual routes are propagated. PATCH The reason for this behavior is that, prior to this patch, the range is deleted from the area's list, so when ospf_abr_manage_discard_routes() gets called, there is nothing to clean up. The patch removes the discard route as part of the processing of the command line (ospf_area_range_unset()).

2012-10-25lib: improve fletcher checksum validationJR Rivers
OVERVIEW The checksum used in OSPF (rfc2328) is specified in rc905 annex B. There is an sample implementation in rfc1008 which forms the basis of the quagga implementation. This algorithm works perfectly when generating a checksum; however, validation is a bit problematic. The following LSA (generated by a non-quagga implementation) is received by quagga and marked with an invalid checksum; however, it passes both the rfc905 and rfc1008 validation checks. static uint8_t lsa_10_121_233_29[] = { 0x0e, 0x10, 0x02, 0x03, 0x09, 0x00, 0x35, 0x40, 0x0a, 0x79, 0xe9, 0x1d, 0x80, 0x00, 0x00, 0x03, 0x00, 0x8a, 0x00, 0x1c, 0xff, 0xff, 0xff, 0xe0, 0x00, 0x00, 0x36, 0xb0 }; LS Type: Summary-LSA (IP network) LS Age: 3600 seconds Do Not Age: False Options: 0x02 (E) Link-State Advertisement Type: Summary-LSA (IP network) (3) Link State ID: 9.0.53.64 Advertising Router: 10.121.233.29 (10.121.233.29) LS Sequence Number: 0x80000003 LS Checksum: 0x008a Length: 28 Netmask: 255.255.255.224 Metric: 14000 You'll note that one byte of the checksum is 0x00; quagga would calculate the checksum as 0xff8a. It can be argued that the sourcing implementation generates an incorrect checksum; however, rfc905 indicates that, for 1's complement arithmetic, the value 255 shall be regarded as 0, thus either values are valid. EXPLANATION The quagga ospfd and ospf6d implementations operate by copying the PDU's existing checksum in a holding variable, calculating the checksum, and comparing the resulting checksum to the original. As a note, this implementation has the side effect of modifying the contents of the PDU. Evaluation of both rfc905 and rfc1008 shows that checksum validation should involve calculating the sum over the PDU and checking that both resulting C0 and C1 values are zero. This behavior is enacted in the rfc1008 implementation by calling encodecc with k = 0 (checksum offset); however, this functionality had been omitted from the quagga implementation. PATCH This patch adds the ability to call the quagga's fletcher_checksum() with a checksum offset value of 0xffff (aka FLETCHER_CHECKSUM_VALIDATE) which returns the sum over the buffer (a value of 0 indicates a valid checksum). This is similar to the mechanism in rfc1008 when called with k = 0. The patch also introduces ospf_lsa_checksum_valid(). ospf6d had it's own implementation of the fletcher checksum in ospf6_lsa_checksum(); it's the same algorithm as in fletcher_checksum(). This patch removes the local implementation in favor of the library's as well as creates and uses ospf6_lsa_checksum_valid(). quagga's ISIS implementation suffers from the same problem; however, I do not have the facilities to validate a fix to ISIS, thus this change has been left to the ISIS maintainers. The function iso_csum_verify() should be reduced to running the fletcher checksum over the buffer using an offset of 0.

2012-09-26lib/table: add route_table_get_next() and iteratorAvneesh Sachdev
* lib/table.[ch] - Add a function (route_table_get_next()) to get the route_node in a tree that succeeds a given prefix in iteration order. This allows one to reliably walk nodes in a tree while allowing modifications, and is useful for achieving scale and performance. Other approaches are also possible -- the main plus point of this one is that it does not require any state about the walk to be maintained in the table data structures. - Add an iterator for walking the nodes in a tree. This introduces a new structure (route_table_iter_t) and the following main functions. route_table_iter_init() route_table_iter_pause() route_table_iter_next() route_table_iter_cleanup() The iterator normally uses node pointers and the existing route_next() function to walk nodes efficiently. When an iteration is 'paused' with route_table_iter_pause(), it stores the last prefix processed. The next call to route_table_iter_next() transparently invokes route_table_get_next() with the prefix to resume iteration. * bgpd/bgp_table.[ch] Add wrappers for the new table features described above. * tests/table_test.c Add tests for the new table code.

Initialize the route_table with a delegate, such that the nodes in the table are bgp_node structures. - Add inline wrappers that call route_table functions underneath, and accept/return the correct BGP types. * bgpd/bgp_route.c Change some code to use inline wrappers instead of accessing fields of nodes/tables directly.

The alternative node is expected to embed the fields of a route_node using ROUTE_NODE_FIELDS. - Add route_table_init_with_delegate() to create a new table with a given delegate. - Make route_table_init() a thin wrapper around route_table_init_with_delegate(). The delegate it passes in simply creates/destroys route_node structures as before. - Add a user data pointer (info) to the route_table structure. This can be used by a client to keep per-table state.

It is also very useful when reporting bugs on the official Quagga mailing lists. There are two ways of utilsing this functionality: a) ./configure --with-pkg-extra-version=-wmo1 b) EXTRAVERSION=-wmo1 ./configure The latter is a common way for many distributions to add extra version strings to signify their own patch level to a given package. Also, minor whitespace fix in configure summary.
