* ospf_ism.h: (OSPF_ISM_TIMER_OFF) Improve macro syntax by enclosing
in 'do {...} while(0)'.

2005-11-14 Paul Jakma <paul.jakma@sun.com>
* (general) pass struct work-queue to callback functions.
* workqueue.h: (struct work_queue) move the state flag
variables to end.
Add an opaque pointer to spec, for user-data global to the
queue.
Pass reference to work_queue to all callbacks.
* workqueue.c: (work_queue_item_remove) pass ref to workqueue
to user callbacks.
(work_queue_run) ditto.
|
|
* zebra_rib.c: (rib_process) convert to new workqueue specs and
shut up gcc, which complains about cast from void via
function parameters, for some dumb reason. Do the cast
inside the function instead.
(rib_queue_qnode_del) ditto.
(rib_queue_init) no need for the casts anymore.

2005-11-14 Paul Jakma <paul.jakma@sun.com>
* configure.ac: Tell gcc we like C99.
[bug #231] Check and test for stdint.h.
* lib/zebra.h: [bug #231] include stdint, if its there.
|
|
* (general) Add state to detect queue floods. There's no sense
trying to be sparing of CPU resources, if the queue is
flooding and using ever more memory resources. we should just
get on with clearing the queue.
The sense of delay and hold were wrong way around, fix.
* workqueue.h: (struct work_queue) Add status bitfield. Add
'flood' integer to workqueue spec. Add runs_since_clear
counter to workqueue.
* workqueue.c: (work_queue_new) set defaults for delay, hold
and flood.
(work_queue_add) initial schedule should use delay, not hold.
(show_work_queues) Print flood field, conserve whitespace.
(work_queue_unplug) use delay, not hold.
(work_queue_run) consecutive runs should be seperated by hold
time, not delay.
Keep track of number of consecutive runs, go into 'overdrive'
if queue is being flooded, we can't avoid making heavy use of
resources, better to use CPU than ever more RAM.

* ospfd.c: (ospf_new) stub-shutdown should just default to
unconfigured, too strange otherwise.
(ospf_finish_final) t_opaque_lsa_self TIMER_OFF should be
preprocessor conditional on HAVE_OPAQUE_LSA.
* ospfd.h: (struct ospf) remove the SHUTDOWN_DEFAULT define.
no longer used, plus it wasn't in range that the command
accepted.
* ospf_zebra.h: Depends on vty.h, include it.

2005-11-12 Alexander Gall <gall@switch.ch>
* See [quagga-dev 1815]
* kernel_socket.c: (rtm_write) Use SAROUNDUP when HAVE_SIN_LEN
is not available.
* rt_socket.c: (kernel_rtm_ipv6(_multipath)) set family to
AF_INET6 on ipv6 routes.
2005-11-12 Paul Jakma <paul.jakma@sun.com>
* kernel_socket.c: Add RTA_NAME_GET macro to extract name from
sockaddr_dl. Add some more RTF_ flags.
* (ifan_read) Add some debug messages.
* (ifm_read) Add more debug messages. More robust cross-checks
of index against name.
Fall back to by-name lookup if the index lookup fails, future
proofing more than anything else.
(ifam_read_mesg) Read RTA_IFP. Add debug messages.
(ifam_read) More debug. If there's an RTA_IFP and it isn't
the name of the interface, save it as the label.
(rtm_read_mesg) Read RTA_IFP.
(rtm_read) allow name to be retrieved.
(rtmsg_debug) expand on the debug message.

2005-11-12 Paul Jakma <paul.jakma@sun.com>
* routemap.c: (vty_show_route_map_entry) call action is
seperate from exit action, latter should still be printed
regardless of whether a call is specified.
|
|
|
|
|
|
* NEWS: Update.
* configure.ac: Bump to 0.99.2
|
|
|
|
2005-11-11 Paul Jakma <paul.jakma@sun.com>
* quagga.info: update auto-built file. Methinks it's time to
remove from CVS..
|
|
2005-11-11 Paul Jakma <paul.jakma@sun.com>
* kernel_socket.c: (ifm_read) arithmetic on void pointer
warning.
(ifam_read) Fix error from connected-with-label merge,
something crept in from the pending Solaris kernel_socket.c
patch which shouldn't have.
|
|
* HACKING: Add recommendation to provide a single Subject
style description to the commit message.
Add some recommendations for ChangeLog.
|
|
2005-11-07 Paul Jakma <paul.jakma@sun.com>
* Makefile.am: snmptrap.texi needs to be listed as a source,
not disted otherwise.
|
|
- quagga.spec.in: introduce dist variable to allow for differences
e.g in buildreqs, pam config files. etc.
|
|
* quagga.info: Update auto-built file
* ospf6d.texi: Add example config
* bgpd.texi: Add example configs. Couple of cleanups of format
and macros.
* routemap.texi: Add an explanation of how route-maps work.
Document the call and exit-policy commands.
|
|
* snmptrap.texi: Contributed documentation, contributors name
is lost (please get in touch). Configuring SNMP for logging
traps.
* snmp.texi: Minor formatting changes.
* quagga.info: Update auto-built file
|
|
* prototype.dev.in: lib/md5-gnu.h is now lib/md5.h
|
|
* ospf_{dump,spf,vty}.c: Oops, use the internal tv_sub
function rather than unportable timersub.
|
|
- quagga.pam.stack: the old pam_stack way, kept to allow spec file to
backwards compatible (changes to spec file pending local testing)
|
|
|
|
* memtypes.h: Update auto-built file.
|
|
* bgp_damp.c: (bgp_reuse_timer) struct bgp can be retrieved via
the struct bgp_damp_info, no need to guess by using
bgp_get_default().
|
|
* connected.{c,h}: Include memory.h
(connected_add_ipv4) Use MTYPE for ifc label.
(connected_add_ipv6) Also should accept label. Store it in ifp.
(connected_del_ipv4) Taking label as argument is pointless.
* rt_netlink.c: (netlink_interface_addr) update label usage
for connected_{add,delete} functions.
* if_ioctl.c: (if_getaddrs) NULL label for connected_add_ipv6.
* if_ioctl_solaris.c: (interface_list_ioctl) Pass LIFC_NOXMIT
so we also find out about NOXMIT interfaces like VNI.
Bit of hackery to turn interface names into the primary
interface name, later with routing socket messages we only
will about primary interfaces anyway, so we must normalise
the name.
(if_get_addr) take label as argument, so it can
be passed to connected_add.
If label is provided, then it is interface name to issue the
ioctl for address information on, not the ifp name.
(interface_list) List AF_UNSPEC too, just in case.
* if_proc.c: (ifaddr_proc_ipv6) label for connected_add_ipv6.
* interface.c: (if_addr_wakeup) Some very bogus code - sets
IFF_RUNNING - add comment.
(if_refresh)
(ip_address_install) Use MTYPE for ifc label.
* ioctl_solaris.c: (if_mangle_up) New function. Hackery to make
IFF_UP reflect whether any addresses are left on the
interface, as we get signalled for IFF_UP flags change on the
primary interface only. Logical interfaces dont generate
IFINFO, but we do get an RTM_DELADDR.
(if_get_flags) Call if_mangle_up before return.
* kernel_socket.c: (ifam_read) Fixup calls to
connected_{add,delete} to match above changes. Rename gate
variable to brd, less confusing.
Pass the interface name as a label, if it is not same name
as ifp->name.
|
|
* ospf_packet.c: Change level of some warnings to
informational.
|
|
* if.c: (connected_free) use MTYPE for connected label.
memtypes.c: Add MTYPE_CONNECTED_LABEL
|
|
* ospf_apiserver.c: (apiserver_sync_callback) stray semi-colon
* ospf_packet.c: include checksum.h, remove the in_cksum extern
* prototypes.
* ospf_te.h: Add braces, quell warning.
|
|
* zebra.h: BSD BYTE_ORDER define isn't available everywhere,
define if needs be.
* checksum.h: new file. checksum.c exports in_cksum, provide
a header for it.
* checksum.c: (in_cksum) callers shouldn't have to know it uses
a u_short internally, change to void *.
* Makefile.am: Add checksum.h
* command.h: remove bogus trailling slash.
* md5.c: (general) Update it for the twentieth century. ANSI
declarations are widely supported now.. Don't include system
headers, only include zebra.h. Use POSIX types (the
alternative is to define u_int64_t in a portable way - rest
of Quagga needs same cleanup).
Make endian-conditional code be compiler conditional rather
than preprocessor conditional, so that breakage gets noticed
quicker.
* md5.h: POSIX types. Get rid of the odd __P() non-ANSI capable
compiler compatibility hack.
|
|
* ripd.c: (rip_response_process) Instead of calling
rip_interface.c:if_valid_neighbor(), call the equivalent
library function if_lookup_address().
* rip_interface.c: (if_valid_neighbor) Remove function, since it is
essentially equivalent to the if_lookup_address() library function.
* ripd.h: (if_valid_neighbor) Remove function declaration.
|
|
* ospfd.texi: Document the new spf and max-metric commands, and
the additional form of dead-interval. Add documentation for
various other commands. Cleanup misc stuff, citations, etc.
Add some example configurations.
* overview.texi: RFC3137 support added.
* Makefile.am: Make quagga.pdf depend on the _TEXINFOS
variable, this still doesn't fix the dependency though,
sadly.
|
|
* (general) RFC3137 stub-router support
* ospfd.h: Add OSPF_OUTPUT_COST_INFINITE define.
(struct ospf_master) Add a OSPF_MASTER_SHUTDOWN flag for
options, to allow shutdown to distinguish between complete
shutdown and shutdown of a subset of ospf instances.

and shutdown time for stub-router.
Add t_graceful_shutdown struct thread, timer for graceful
shutdown, if needed.

stub-router for an area. Add flags for ADMIN, IS and WAS
states.
Add t_stub_router, timer thread to resend router-lsa for an
area.

either the given lnks cost or infinite cost if stub-router is
in effect.
(lsa_link_{ptop,broadcast,virtuallink,ptomp}_set) use
previous function for transit-links.
(ospf_stub_router_timer) timer thread for end of startup stub

remove call to exit, as ospf_terminate now deals with
exiting.
* ospf_route.c: (ospf_terminate) removed, now in ospfd.c.
* ospf_vty.c: (show_ip_ospf_area) print out state of
stub-router, if active.
(show_ip_ospf) print out configuration of stub-router
support, and details of graceful-shutdown if the timer is
active.
((no)?ospf_max_metric_router_lsa_{admin,startup,shutdown}) new
commands to (de-)?configure stub-router support.
(config_write_stub_router) write out config of stub-router.
(ospf_config_write) call previous.
(ospf_vty_init) install the new stub-router commands.

shutdown.
(ospf_graceful_shutdown_timer) timer thread wrapper for
graceful-shutdown.
(ospf_graceful_shutdown_check) check whether to setup timer

(ospf_finish) new function, exported wrapper around
ospf_graceful_shutdown_check.
(ospf_finish_final) complete shutdown of an instance.
Add missing TIMER_OFF's of two timer threads.

|
|

explicitely.
|
|
* (general) static/extern functions and definitions.
* rip_interface.h: new file, export the public functions from
rip_interface.c
|
|
* ospf_apiserver.c: (ospf_apiserver_term) This function should
not have side-effects (eg segv) if no apiserver instances are
active, ie be robust.
|
|
* ospf_vty.c: (show_ip_ospf) fix display of SPF timer if it
has not yet been run.
|
|
* ospf_dump.c: (ospf_timeval_dump) fix ms adjustment, thanks to
Andrew Schorr.
* ospf_vty.c: (ospf_config_write) fix write out of spf timers
configuration.
|
|
* (general) SPF millisecond resolution timer with adaptive,
linear back-off holdtime. Prettification of ospf_timer_dump.
* ospf_dump.c: (ospf_timeval_dump) new function. The guts of
ospf_timer_dump, but made to be more dynamic in printing out
the relative timeval, sliding the precision printed out
according to the value.
(ospf_timer_dump) guts moved to ospf_timeval_dump.
* ospf_dump.h: export ospf_timeval_dump.
* ospf_flood.c: (ospf_flood) remove gettimeofday, use
the libzebra exported recent_time instead, as it's not
terribly critical to have time exactly right - the dropped
LSA will be retransmited to us if we don't ACK it.
* ospf_packet.c: (ospf_ls_upd_timer) Ditto, but here we're
not transmitting, just putting LSA back on update transmit list.
* ospfd.h: delay and holdtimes should be unsigned.
Add spf_max_holdtime and spf_hold_multiplier.
Update default defines for delay and hold time to be in msec.
(struct ospf) change the SPF timestamp to a struct timeval.
Remove ospf_timers_spf_(un)?set.
* ospfd.c: (ospf_timers_spf_{set,unset}) removed.
(ospf_new) initialise spf_max_holdtime and spf_hold_multiplier
* ospf_spf.c: (ospf_spf_calculate) SPF timestamp is a timeval
now, update with gettimeofday.
(ospf_spf_calculate_schedule) Change SPF timers to millisecond
resolution.
Make the holdtime be adaptive, with a linear increase in
holdtime ever consecutive SPF run which occurs within holdtime
of previous SPF, bounded by spf_max_holdtime.
* ospf_vty.c: Update spf timers commands.
(ospf_timers_spf_set) trivial helper.
(ospf_timers_throttle_spf_cmd) new command to set SPF delay,
initial hold and max hold times with millisecond resolution.
(ospf_timers_spf_cmd) Deprecated. Accept the old values,
convert to msec, truncate to new limits.
(no_ospf_timers_throttle_spf_cmd) set timers to defaults.
(no_ospf_timers_spf_cmd) deprecated form, same as previous.
(show_ip_ospf_cmd) Display SPF parameters and times.
(show_ip_ospf_neighbour_header) Centralise the 'sh ip os ne'
header.
(show_ip_ospf_neighbor_sub) Fix the field widths. Get rid of
the multiple spaces which were making the lines even longer.
(show_ip_ospf_neighbor_cmd) Use show_ip_ospf_neighbour_header
(show_ip_ospf_neighbor_all_cmd) ditto and fix the field
widths for NBMA neighbours.
(show_ip_ospf_neighbor_int) Use header function.
(show_ip_ospf_nbr_nbma_detail_sub) use sizeof for timebuf,
local array - safer.
(show_ip_ospf_neighbor_detail_sub) ditto
(ospf_vty_init) install the new SPF throttle timer commands.
|
|
* sockopt.c: (setsockopt_multicast_ipv4) If IP_ADD_MEMBERSHIP
fails with errno equal to EADDRINUSE, then issue an info
message and try IP_DROP_MEMBERSHIP followed by IP_ADD_MEMBERSHIP.
|
|
* (general) OSPF fast, sub-second hello and 1s dead-interval
support. A warning fix. Millisec support for ospf_timer_dump.
Change auto-cost ref-bandwidth to add a comment to write out
of config, rather than printing annoying messages to vty on
startup.
* ospf_dump.c: (ospf_timer_dump) Print out milliseconds too.
Callers typically specify a length of 9, so most see
millisecs unless they specify the additional length.
* ospf_interface.h: (struct ospf_interface) new interface param,
fast_hello.
* ospf_interface.c: (ospf_if_table_lookup) add brackets,
gcc warning fix.
(ospf_new_if_params) Initialise fast_hello param.
(ospf_free_if_params) Check whether fast_hello is configured.
(ospf_if_new_hook) set fast_hello to default.
* ospf_ism.h: Wrap OSPF_ISM_TIMER_ON inside do {} while (0) to
prevent funny side-effects from its if statement when this
macro is used conditionally by other macros.
(OSPF_ISM_TIMER_MSEC_ON) new macro, set in milliseconds.
(OSPF_HELLO_TIMER_ON) new macro to set hello timer according
to whether fast_hello is set.
* ospf_ism.c: Update all setting of the hello timer to use
either OSPF_ISM_TIMER_MSEC_ON or OSPF_HELLO_TIMER_ON. The
former is used when hello is to be sent immediately.
* ospf_nsm.c: ditto
* ospf_packet.c: (ospf_hello) hello-interval is not checked
for mismatch if fast_hello is set.
(ospf_read) Annoying nit, fix "no ospf_interface" to be debug
rather than a warning, as it can be perfectly normal to
receive packets when logical subnets are used.
(ospf_make_hello) Set hello-interval to 0 if fast-hellos are
configured.
* ospf_vty.c: (ospf_auto_cost_reference_bandwidth) annoying
nit, don't vty_out if this command is given, it gets tired
quick.
(show_ip_ospf_interface_sub) Print the hello-interval
according to whether fast-hello is set or not.
Print the extra 5 millisec characters from (ospf_timer_dump)
if fast-hello is configured.
(ospf_vty_dead_interval_set) new function, common to all
forms of dead-interval command, to set dead-interval and
fast-hello correctly. If a dead-interval is given, unset
fast-hello, else if a hello-multiplier is set, set
dead-interval to 1 and fast-hello to given multiplier.
(ip_ospf_dead_interval_addr_cmd) use
ospf_vty_dead_interval_set().
(ip_ospf_dead_interval_minimal_addr_cmd) ditto.
(no_ip_ospf_dead_interval) Unset fast-hello.
(no_ip_ospf_hello_interval) Bug-fix, unset of hello-interval
should set it to OSPF_HELLO_INTERVAL_DEFAULT, not
OSPF_ROUTER_DEAD_INTERVAL_DEFAULT.
(config_write_interface) Write out fast-hello.
(ospf_config_write) Write a comment about
"auto-cost reference-bandwidth" having to be equal on all
routers. Hopefully just as noticeable as old practice of
writing to vty, but less annoying.
(ospf_vty_if_init) install the two new dead-interval
commands.
* ospfd.h: Add defines for OSPF_ROUTER_DEAD_INTERVAL_MINIMAL
and OSPF_FAST_HELLO_DEFAULT.
|
|
* memory.c: (show_memory_vty) Omit zero statistics. Print separators
only if some non-zero stats have been printed in between.
(show_separator) New function to print a separator.
(show_memory_all) Keep track of whether a separator is needed
between the different memory statistics groups.
|
|
* ripd.c: rip_create_socket() for each packet, it does not bind to the
proper interfaces because we forget to use the from address when
it is specified.
|
|
* memtypes.h: Add MTYPE_OSPF_VERTEX_PARENT (to match memtypes.c).
|
|
* (general) SPF memory management cleanup and fix for rare
double-free bug.
* ospf_spf.h: (struct vertex_parent) New struct to hold parent
specific data, eg the backlink and the parent vertex pointer,
and point to the appropriate general struct vertex_nexthop.
(struct vertex_nexthop) remove parent vertex pointer, so
this struct can be shared across vertices.
(struct vertex) rename list child to list children. Remove
list of nexthops, replace with list of vertex_parents.
* ospf_spf.c: (update_stat) trivial, remove cast from void *.
(vertex_nexthop_new) remove init of parent - field is gone
from struct vertex_nexthop.
(ospf_canonical_nexthops_free) Remove the canonical
vertex_nexthop memory objects. These are the vertex_nexthops
attached to the first level of router vertices from the root.
(vertex_parent_new) new function, create a vertex_parent.
(vertex_parent_free) ditto, but free it.
(ospf_vertex_new) Update to match changes to struct vertex.
(ospf_vertex_free) Recursively free a struct vertex and its
children. The parent list is used as a reference count.
vertex_nexthops must be free seperately, if required.
(ospf_vertex_dump) update to match struct vertex changes.
Print out backlink of parents too.
(ospf_vertex_add_parent) ditto.
(ospf_lsa_has_link) update comment.
(ospf_nexthop_add_unique) removed, not needed anymore.
(ospf_nexthop_merge) ditto.
(ospf_spf_consider_nexthop) renamed to ospf_spf_add_parent.
Simplified to just create vertex_parent and add it.
(ospf_spf_flush_parents) new function, flush out the parent
list.
(ospf_nexthop_calculation) Take the relevant route_lsa_link
as an argument, which simplifies things and removes the need
for the hack in ospf_nexthop_add_unique - ospf_spf_next
already knew exactly which link the cost calculated was for.
Update to match struct vertex changes too.
(ospf_spf_next) Don't create a vertex for W unnecessarily, if
it's there's a vertex already created for W, use it, and
hence there's no need to free it either.
Update some manipulation/comparisons of distance to match.
Flush the parent list if a lower cost path is found.
(ospf_spf_route_free) unused, removed.
(ospf_spf_dump) match the struct vertex changes, and dump the
ifname if possible.
(ospf_spf_calculate) At end of SPF, free the canonical nexthops
and call ospf_vertex_free on the root vertex to free the
entire tree.
* ospf_interface.c: (ospf_vl_set_params) match struct vertex
changes.
* ospf_route.c: (ospf_intra_route_add) ditto
(ospf_route_copy_nexthops_from_vertex) ditto
* memtypes.c: (memory_list_ospf) Add MTYPE_OSPF_VERTEX_PARENT.
|
|
* ospf_api.c: sign warnings.
* ospf_apiserver.c: sign warning and convert all the struct
in_addr initialisations so as not to make assumptions about
how this struct is organised, initialise the s_addr member
explicitely.
* ospf_packet.c: Add const qualifier to auth_key.
|
|
* quagga.texi: Rejiggle the copyright sections a bit, seems to
make makeinfo happier and generates info pages again on FC4.
* quagga.info: Update this auto-built file.
