* aspath_test.c: Test bgp_aspath functionality.
* Makefile.am: build aspathtest
* ChangeLog: Fix date of previous commit
|
|
* Makefile.am: bgpd shouldn't list libgp's sources as its own.
Use LDADD.
* bgp_aspath.h:
(struct assegment) New struct, abstract representation of a
list of AS_PATH segments and the contained ASNs.
(struct aspath) Remove the raw-data related
fields, reference the abstract struct assegment instead.
Remove several other computed fields, it's just a
headache to maintain them and they're cheap to compute from
struct assegment.
(aspath_parse) parse a stream, not a pointer to raw data.
(aspath_count_{hops,confeds,size}) helpers to access
information formerly directly contained in struct aspath.
(aspath_snmp_pathseg) Helper for SNMP, BGP MIB wants
to be able to output hex representation of raw data.
* bgp_aspath.c: (general) partial-rewrite. Store aspath data
as an abstract singly-linked list of abstract segments,
rather than storing the raw data, and parsing it each and
every time. Remove several count/size fields which are cheap
to compute from the abstract segment structure.
(global) Include stream.h, needed for aspath_parse, and
others. Couple of helper macros added.
(struct assegment_header) Just the header, and only the
header.
(assegment_data_{new,free}) convenience functions for
AS_SEG_DATA allocation, the dynamic, per-segment array of
ASNs.
(assegment_{new,free,free_all,dup,dup_all}) convenience
functions for creating struct assegments. The _all forms will
follow the entire chain of segments from the given segment.
(assegment_prepend_asns) new function, prepend an ASN N times
to segment.
(assegment_append_asns) Append a list (array) of ASNs to
segment.
(int_cmp) convenience function for the aspath hash.
(assegment_normalise) new function. Normalise the given
segment chain to meet expectations of Quagga, and to
eliminate differing raw representations of the same paths.
Merge 'runs' of SEQUENCEs into one segment as our internal
segment is not limited by the protocol AS_PATH segment
length. Sort ASNs in SETs.
(aspath_new) Take void argument to quell warnings. Use the
assegment convenience functions.
(assegment_count_{asns,confeds,hops}) new functions to
compute at runtime values previously held in struct aspath.
(aspath_size) ditto.
(aspath_make_str_count) rewritten to stringify new
representation, and to be slightly easier to understand
hopefully.
(aspath_str_update) convenience function, update the aspath
str. Should investigate removing maintained string from
struct aspath, just run-time compute it, as per other fields.
It's just a maintenance headache, would save noticeable
amount of RAM with possibly not much extra run-time cost.
(aspath_dup) use the assegment dup functions.
(aspath_hash_alloc) Take void * argument to satisfy gcc. Use
the proper helper functions to dup data.
(assegments_parse) new function. parse raw AS_PATH data into
struct assegments. Normalise and return the head of the list.
(aspath_parse) Parse a stream, not pointer to raw data and
use assegments_parse to do it.
(assegment_data_put) Write out a single segment data in protocol
form to stream.
(assegment_header_put) ditto but for segment header.
(aspath_put) new function. As per previous but for an entire
struct aspath.
(aspath_snmp_pathseg) wrapper around aspath_put for
bgp_snmp.c. Uses a static buffer sadly.
(aspath_aggregate_as_set_add) rewritten to use assegments.
(aspath_aggregate) ditto
(aspath_{firstas,loop,private_as}_check) ditto
(aspath_{merge,prepend,add_one_as}) ditto
(aspath_cmp_left{_confed}) ditto
(aspath_delete_confed_seq) ditto, plus fixed to properly
delete all leading confed segments.
(aspath_as_add) Just use assegment_append_asns.
(aspath_segment_add) updated to use assegments.
(enum as_token) Add values for confeds
(aspath_gettoken) Add support for confeds
(aspath_str2aspath) ditto
(aspath_key_make) updated to use as_segments. Also, add
segment type into the hash value as appropriate.
(aspath_cmp) updated to use as_segments.
(aspath_print) don't segfault on NULL argument.
* bgp_attr.c: (bgp_attr_aspath) aspath_parse wants the stream
now. No need for manual forwarding of stream.
(bgp_packet_attribute) empty aspath is now denoted by NULL
segment field, length is gone.
Use aspath_size() to determine size.
(bgp_attr_init) Fix declaration, explicitely specify void
arg.
(bgp_dump_routes_attr) Use aspath_size() to determine size.
* bgp_route.c: (bgp_info_cmp) use the aspath_count_* functions.
(bgp_rib_withdraw) remove unused variable. Use
aspath_count_hops.
* bgp_snmp.c: (bgp4PathAttrTable) raw data is gone, use
aspath_snmp_pathseg to get the representation.
|
|
* bgp_vty.c: (bgp_vty_init) gcc 4 compile fix. static
function declarations shouldn't be inside functions.
* bgp_dump.c: (bgp_dump_interval_add) ditto.
|
|
- Steal some changes from Fedora spec file:
- Add with_rtadv variable
- Test for groups/users with getent before group/user adding
- Readline need not be an explicit prerequisite
- install-info delete should be postun, not preun
|
|
* test-buffer.c: include memory.h
(main) call memory_init().
|
|
* heavy-wq.c: (slow_func_del,slow_func_err) make them take
void * argument to shut up silly gcc warning.
|
|
* command.c: (install_element) be more robust. Eg, cmd_init
need not have been called, some applications may use other
library subsystems, which call install_element, without the
application wanting commands and hence not calling cmd_init.

|
on).
* isis_lsp.c (lsp_build_nonpseudo): Use stream_reset() instead of
touching endp directly.
* isis_lsp.c (lsp_build_pseudo): Ditto.
|
|
Similar fix to the one commited to lsp_build_nonpseudo() some days
ago.

anything. These floats to longs and vice versa casts are starnge
indeed.
* isis_pdu.c: As we don't use %z for size_t for now because we support
older compilers, cast them to unsigned long.
Also fix previous changelog entry. Isisd compiles cleanly now again.
|
|
with XCALLOC.
* isis_lsp.c (lsp_build_pseudo): Fix adding ES neighbour.
* isis_tlv.c: More compact free_tlvs() function.
* isis_lsp.c (lsp_build_nonpseudo) : Try to fix one more regression
introduced by stream cleanup. Seek enp to the right place before
starting to fill stream with TLVs.

Forwardport from stable branch.

|
rib_add_ipv6() function so that IPv6 routes in RIB can have correct
metric. No IPv6 routing daemon uses distance yet though.
* zserv.c, connected.c, kernel_socket.c, rt_netlink.c,
rtread_proc.c,zserv.c: Pass metric and distance info to the
rib_add_ipv6().
Forwardport from stable branch.
|
|
introduced long time ago with route server patch. Hopefully
it's last case to fix - route-server client not in peer group.

|
|
* configure.ac: Add -fno-omit-frame-pointer after -Os in default
cflags, just to be sure.
Fedora's readline library does not itself link to termcap, hence
we must pass the result of termcap tests in via OTHER-LIBRARIES
argument, otherwise the test of main in readline will fail due to
missing termcap systems. On systems like Debian, -ltermcap
is not needed for the readline test, because libreadline already
links to it.
|
|
against libreadline and friends.
|
|
* vtysh.c: Add support for BGP_IPV6M_NODE
|
|
* bgp_vty.c: (general) Add support for BGP IPv6 Multicast SAFI
commands and BGP_IPV6M_NODE.
|
|
* command.h: (enum node_type) Add BGP_IPV6M_NODE
* command.c: (node_parent) Handle BGP_IPV6M_NODE node
(config_exit, config_end) ditto
* vty.c: (vty_end_config) Handle BGP_IPV6M_NODE node
|
|
* bgp_route.h: (struct bgp_info) add a new flag, BGP_INFO_REMOVED.
BGP_INFO_VALID is already overloaded, don't care to do same thing
to STALE or HISTORY.
* bgpd.h: (BGP_INFO_HOLDDOWN) Add INFO_REMOVED to the macro, as a
route which should generally be ignored.
* bgp_route.c: (bgp_info_delete) Just set the REMOVE flag, rather
than doing actual work, so that bgp_process (called directly,
or indirectly via the scanner) can catch withdrawn routes.
(bgp_info_reap) Actually remove the route, what bgp_info_delete
used to do, only for use by bgp_process.
(bgp_best_selection) reap any REMOVED routes, other than the old
selected route.
(bgp_process_rsclient) reap the old-selected route, if appropriate
(bgp_process_main) ditto
(bgp_rib_withdraw, bgp_rib_remove) make them more consistent with
each other. Don't play games with the VALID flag, bgp_process
is async now, so it didn't make a difference anyway.
Remove the 'force' argument from bgp_rib_withdraw, withdraw+force
is equivalent to bgp_rib_remove. Update all its callers.
(bgp_update_rsclient) bgp_rib_withdraw and force set is same as
bgp_rib_remove.
(route_vty_short_status_out) new helper to print the leading
route-status string used in many command outputs. Consolidate.
(route_vty_out, route_vty_out_tag, damp_route_vty_out,
flap_route_vty_out) use route_vty_short_status_out rather than
duplicate.
(route_vty_out_detail) print state of REMOVED flag.
(BGP_SHOW_SCODE_HEADER) update for Removed flag.

Interface should be specified by name now.

|
|
print info about it.
Fixes bugzilla #213. [backport candidate]
|
|
|
|
* README.txt: point to the opensolaris.org sources for the SMF
manifest class scripts. Make step 3 slightly more explicit about
what 'this directory' is.
|
|
* ripd.c: (general) Fix previous commit, broke multicast bind and
hence setting of source port, which broke communication with
non-borken ripd. Fix removes more stuff from rip_interface.c
than it adds to ripd.c ;)
(rip_create_socket) the to argument really is a from argument,
rename it. Set the source port to RIP port unconditionally, it's
required.
(rip_send_packet) Set from address correctly for multicast.
(rip_output_process) trivial: num can be BSS specified, rather
than in body.
* rip_interface.c: (rip_interface_multicast_set) strip out
redundant stuff related to bind, which rip_create_socket does.
Just make it set the multicast socket option, as per the
interface concerned, no more.
|
|
* Makefile.am: (EXTRA_DIST) Add the trailing slash back in which
greg left out - tools bits weren't being included in dist,
which broke rpm builds :).
|
|
* ospf6_asbr.c: (ospf6_asbr_redistribute_add) Fix sense of testing
of route_map_apply return code, it can return many things other
than RMAP_MATCH which do not indicate DENY. Should test explicitly
for equality to RMAP_DENYMATCH instead.

patches and lose because of old autoconf/automake versions have the
opportunity to find tout what to do.
|

values.h, where MAXLONG is defined, is deprecated as well.
Thanks to Greg for noticing and to Rivo for fix.

clarify make (BSD make not working is a bug, and GNU make not working
is a really serious bug)
declare POSIX.2 as a semi-requirement, with notion that workarounds
for non-posix must be clean.
list OS versions for which not working is a bug.
add instructions for using info and emacs/info, and remove admonition
to use pinfo
add note about GNU awk (really needed? BSD awk)
Note that NetBSD 2.99.15 has texinfo 4.7
|
|
* getopt.h: Don't declare getopt (rather than getopt_long), since
quagga doesn't need it.
* getopt.c (getopt): Don't define getopt.
Fixes build breakage on NetBSD, and seems likely to work on most
platforms since it avoids the entire issue of system getopt
declarations and whether they conform to POSIX.2. Note that this
change doesn't address system getopt_long declarations, but also
doesn't change anything about getopt_long.

2005-05-27. While ecommunity fix seems to be correct, community case
isn't.

* interface.c: (if_delete_update) should always be available, not
just on RTM_IFANNOUNCE/NETLINK systems.
* kernel_socket.c: (ifan_read) only call if_delete_update when
interface departs, dont if_delete, because we wish to retain
interface configuration state even when interfaces are removed.
(ifm_read) If we dont have RTM_IFANNOUNCE, then transitioning
to down state is only chance we have to clean up interface in case
it is deleted (eg Solaris down -> unplumb -> plumb up).
* redistribute.c: (zebra_interface_delete_update) should always be
available, we /will/ call it now on all systems, via
if_delete_update.
* zserv.c: (zsend_interface_delete) ditto
(zsend_interface_address) Update the call-flow diagramme, to
reflect that if_delete_update /is/ now called on all systems,
potentially.
* zserv.h: (zsend_interface_delete) unconditionally exported, as
above.
|
|
* prefix.c: (prefix_ipv4_new, prefix_ipv6_new): Call prefix_new
to allocate the memory to make sure that all struct prefix pointers
point to objects of the same length (avoids memory overruns
on struct prefix assignments).
(prefix_ipv4_free, prefix_ipv6_free): Simply call prefix_free.
It is interesting to note that these functions are never actually
called anywhere in the code. Instead prefix_free was already
being called directly, despite the previous MTYPE incompatibility.
[backport candidate]

|
* prefix.c: (ip_masklen) While loop should test that 'pnt' pointer is
in range before dereferencing it.
[backport candidate]
|
|
* ospf_abr.c: (ospf_abr_announce_network_to_area) SET_FLAG
should be on lsa not old, which may be freed for one thing,
obviously.
|
|
* ospfd.h: add OSPF_ABR_DEFAULT for convenience, make
OSPF_ABR_CISCO be the default ABR type.
* ospfd.c: (ospf_new) initialise abr_type to OSPF_ABR_DEFAULT
* ospf_vty.c: (no_ospf_abr_type_cmd) add standard as a negatable
abr_type. default abr_type should be OSPF_ABR_DEFAULT.
(ospf_config_write) test whether default abr_type against
OSPF_ABR_DEFAULT, rather than any specific ABR_TYPE.
|
|
ARM in general.
|
|
* vtysh_user.c: rename struct user to struct vtysh_user to avoid
clashes with sys/user.h on ARM.
|
|
[backport candidate]
|
|
* kernel_socket.c: (RTA_{ADDR,ATTR}_GET) fix mistake, NULL check
should be on DEST argument
|
|
* (global) Extern and static'ification, with related fixups
of declarations, ensuring files include their own headers, etc.
if_ioctl.c: (interface_info_ioctl) fix obvious arg mis-order in
list loop
|
|
* (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.
|
|
* INSTALL.quagga.txt: GNU make is required now, because of manual
automatic rules in solaris/Makefile.am. (If someone knows how
to do these in a better way..).
GNU AWK is required for CVS checkout builds.

IP source address in the OSPF packets. It was sometimes problematic
in actual operation (needed some operational cost: restarting
all-neighbor routers when I/F NIC was changed). Due to this change,
a previously safe case, attaching multiple interface to the same
link will now be dengerous and will not work. Remedy to that should
be applied later.

inactivity_timer() deletes the neighbor from the neighbor_list, it
cannot be called by thread_execute() from inner side of the
neighbor_list for-loop.
(Although crash was already fixed in Quagga, it's better follow the
GNU Zebra logic).

* getopt.h: add further tests for full getopt declaration on
various systems.
