* ospf_packet.c: (ospf_write_frags) Enhance error message to
show MTU. Also make function static.
(ospf_write) Enhance error message to show interface name and MTU.
Also make function static.

* ospfd.h: Add new field struct stream *ibuf to struct ospf.
* ospfd.c: (ospf_new) Check return code from ospf_sock_init.
Allocate ibuf using stream_new(OSPF_MAX_PACKET_SIZE+1).
(ospf_finish) Call stream_free(ospf->ibuf.
* ospf_packet.c: (ospf_read) Call stream_reset(ospf->ibuf) and then
pass it to ospf_recv_packet for use in receiving the packet
(instead of allocating a new stream for each packet received).
Eliminate all calls to stream_free(ibuf).
(ospf_recv_packet) The struct stream *ibuf is now passed in as
an argument. No need to use recvfrom to peek at the packet
header (to see how big it is), just use ospf->ibuf which is
always large enough (this eliminates a system call to recvfrom).
Therefore, no need to allocate a stream just for this packet,
and no need to free it when done.

* ospf_packet.c: (ospf_stream_copy) remove
(ospf_packet_dup) use stream_copy instead of ospf_stream_copy
|
|
* ospf_packet.c: (ospf_recv_packet) If there is somehow a runt
packet in the queue, it must be discarded. Improve warning messages.
Fix scope to static.
(ospf_read) Fix bug: should reset the read thread in all cases
to make sure we continue to get incoming messages.

* ospf_packet.c: (ospf_recv_packet) Fix silly error wrt allocating
ibuf. Thanks Andrew.

* ospf_interface.h: Reduce structure padding by putting new u_char
field multicast_memberships in a better spot (grouped with
other u_char fields type and state).
2005-02-08 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* ospf_interface.h: Improve passive_interface comment. Add new
multicast_memberships bitmask to struct ospf_interface to track
active multicast subscriptions. Declare new function
ospf_if_set_multicast.
* ospf_interface.c: (ospf_if_set_multicast) New function to configure
multicast memberships properly based on the current
multicast_memberships status and the current values of the
ospf_interface state, type, and passive_interface status.
(ospf_if_up) Remove call to ospf_if_add_allspfrouters (this is
now handled by ism_change_state's call to ospf_if_set_multicast).
(ospf_if_down) Remove call to ospf_if_drop_allspfrouters (now
handled by ism_change_state).
* ospf_ism.c: (ospf_dr_election) Remove logic to join or leave
the DRouters multicast group (now handled by ism_change_state's call
to ospf_if_set_multicast).
(ism_change_state) Add call to ospf_if_set_multicast to change
multicast memberships as necessary to reflect the new interface state.
* ospf_packet.c: (ospf_hello) When a Hello packet is received on a
passive interface: 1. Increase the severity of the error message
from LOG_INFO to LOG_WARNING; 2. Add more information to the error
message (packet destination address and interface address);
and 3. If the packet was sent to ospf-all-routers, then try
to fix the multicast group memberships.
(ospf_read) When a packet is received on an interface whose state
is ISM_Down, enhance the warning message to show the packet
destination address, and try to update/fix the multicast group
memberships if the packet was sent to a multicast address.
When a packet is received for ospf-designated-routers, but the
current interface state is not DR or BDR, then increase the
severity level of the error message from LOG_INFO to LOG_WARNING,
and try to fix the multicast group memberships.
* ospf_vty.c: (ospf_passive_interface) Call ospf_if_set_multicast for
any ospf interface that may have changed from active to passive.
(no_ospf_passive_interface) Call ospf_if_set_multicast for
any ospf interface that may have changed from passive to active.

adding the interface flags.
2005-01-30 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* ospf_network.c: (ospf_sock_init) Save errno before calling
ospfd_privs.change.
2005-01-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* ospf_packet.c: (ospf_packet_add) If oi->obuf is NULL, print
an error message and return.
(ospf_read) If the interface state is ISM_InterfaceDown, issue
a warning message and ignore the packet.
2005-01-10 Greg Troxel <gdt@fnord.ir.bbn.com>
* ospf_packet.h: Remove commented out definition of
OSPF_MAX_PACKET; neither it or the uncommented one are used any more.
* ospf_packet.c (ospf_make_ls_upd): Leave room for authentication
when deciding if an update will fit.
(ospf_packet_authspace): Factor out calculation of size required
for authentication.
(ospf_make_db_desc): Use ospf_max_packet, not OSPF_MAX_PACKET.

messages from LOG_WARNING to LOG_INFO, since this seems to be
normal.
2004-12-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* ospf_packet.c: (ospf_read) Always look up the interface if
ospf_recv_packet returns NULL ifp, since some platforms such
as Solaris 8 appear to support ifindex retrieval but don't.
2004-12-22 Hasso Tepper <hasso at quagga.net>
* ospf_dump.c: Show debug configuration in vtysh.
* ospf_vty.c: Fix "show ip ospf" output. Router can't be elected in
any case if it's configured as "translate-never".
* ospf_lsdb.[ch]: New function to calculate sum of checksums.
* ospf_vty.c: Bugfix to show really number of AS external LSAs, not
number of all LSAs with AS scope, this includes opaque as LSAs as
well, show this number separately. Show numbers and sums of
checksums for each type of LSAs.
* ospf_lsa.c: Calculate checksum before putting LSA into database.
2004-12-15 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

message and in comment.
(ospf_db_desc) Warning message that a packet is being discarded
should give the router id of the packet source. Fix spelling
of packet in two warning messages.
(ospf_ls_req) Warning message that a link state request is being
discarded should give the router id of the neighbor that sent it.
2004-11-26 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* ospf_main.c: Remove #include "debug.h" (was not being used, and

2004-11-25 Hasso Tepper <hasso at quagga.net>
* ospf_main.c: Make group to run as configurable.
2004-11-15 Greg Troxel <gdt@fnord.ir.bbn.com>

and works (lib/zebra.h provides if OS doesn't).
2004-11-15 Paul Jakma <paul@dishone.st>
* ospf_{apiserver,te}.c: ospf_lsa_free's should be ospf_lsa_unlock.
2004-11-12 Paul Jakma <paul@dishone.st>
* ospf_ia.c: (process_summary_lsa) Only an ABR has any reason to
ignore stub area summary default. Even so it seems a strange
check, add a comment to that effect.
2004-11-04 Paul Jakma <paul@dishone.st>
* ospfd.c: (ospf_network_match_iface) revert to previous network
statement match behaviour.
2004-11-02 Paul Jakma <paul@dishone.st>
* ospf_packet.c: (ospf_write_frags) remove iov arg, msg already points
to it. Add convenience pointer to msg->msg_iov[1], and use this,
fixing the unfortunate borkenness introduced in moving of this code
to a function.
(ospf_write) remove iovp and fix up call to previous.
(ospf_ls_upd_packet_new) cast size to long int - unfortunately
glibc's size_t format modifier is not portable.
2004-10-31 Paul Jakma <paul@dishone.st>
* ospf_packet.c: (ospf_write_frags) Add debug output
(ospf_write) set type early, so we can pass it to
ospf_write_frags.
(ospf_ls_upd_packet_new) print size in debug output when too large
packet is encountered.
* ospf_zebra.c: (ospf_distribute_list_update_timer) Ugly misuse of
THREAD_ARG to store an integer, but it should at least use same
same type to retrieve the value. Assert value is sane.
2004-10-22 Paul Jakma <paul@dishone.st>
* ospf_network.c: (ospf_sock_init) call neutral setsock_ifindex()
function.
* ospf_packet.c: (ospf_read) manually look up ifindex

2004-10-11 Paul Jakma <paul@dishone.st>
* ospf_dump.c: (ospf_ip_header_dump) Assume header is in host order

* ospf_packet.c: (ospf_write) correct call to
sockopt_iphdrincl_swab_htosys which was munging the header.

we have it.
* (global) Const char update and signed/unsigned fixes.
* (various headers) size defines should be unsigned.

2004-10-07 Greg Troxel <gdt@claude.ir.bbn.com>
* ospf_apiserver.c (ospf_apiserver_unregister_opaque_type): Don't
use of variable names 'node' and 'nextnode' to avoid possible
conflict with list macros. Move variable declaration inside for
loop after a statement to top of function.

zebra daemon if it isn't manually overriden in configuration.
2004-09-27 Paul Jakma <paul@dishone.st>
* ospf_dump.c: (ospf_ip_header_dump) Use HAVE_IP_HDRINCL_BSD_ORDER
Apply to offset too. Print ip_cksum, lets not worry about
possible 2.0.37 compile problems.
* ospf_packet.c: (ospf_swap_iph_to{n,h}) Use
HAVE_IP_HDRINCL_BSD_ORDER.
(ospf_recv_packet) ditto.
(ospf_write) Fixup iov argument to ospf_write_frags.
(struct msghdr).msg_name is caddr_t on most platforms.
(ospf_recv_packet) ditto. And msg_flags is not always there
memset struct then set fields we care about rather than
initialise all fields individually.
2004-09-26 Hasso Tepper <hasso at quagga.net>
* ospf_abr.c, ospf_dump.c, ospf_lsa.c, ospf_packet.c, ospf_vty.c,

fixups.
(ospf_apiserver_unregister_opaque_type) fix listnode_delete of

* ospf_packet.c: Fix bugzilla #107
(ospf_packet_max) get rid of the magic 88 constant
(ospf_swab_iph_ton) new function. set ip header to network order,
taking BSDisms into account.
(ospf_swab_iph_toh) the inverse.
(ospf_write) Add support for IP fragmentation, will only work on
linux though, other kernels make it impossible. get rid of the
magic 4 constant.
(ospf_make_ls_upd) Bound check to end of stream, not to
interface mtu.
(ospf_ls_upd_packet_new) New function, allocate upd packet
taking oversized LSAs into account.
(ospf_ls_upd_queue_send) use ospf_ls_upd_packet_new to allocate,
rather than statically allocating mtu sized packet buffer, which
actually was wrong - it didnt take ip header into account, which
should not be included in packet buffer.
(ospf_ls_upd_send_queue_event) minor tweaks and remove
TODO comment.
2004-08-31 David Wiggins <dwiggins@bbn.com>
* ospf_spf.c (ospf_spf_calculate): Many more comments and debug

if interface is in broadcast mode and interface type really is
broadcast. Fixes Bugzilla #108.
2004-08-27 David Wiggins <dwiggins@bbn.com>
* ospf_spf.c (ospf_nexthop_calculation): Initialize address family
in on-stack struct prefix_ipv4. Fixes point-to-multipoint SPF
calculation.
2004-08-26 Greg Troxel <gdt@fnord.ir.bbn.com>
* ospf_packet.c (ospf_recv_packet): adjust size declaration of
buffer used to get interface index so that it compiles on other
than Linux and includes the required alignment space. Probably
this was only working on sparc/sparc64 because most of
sockaddr_dl was not being written.
2004-08-19 Paul Jakma <paul@dishone.st>
* ospf_packet.c: update to match sockopt renames.
2004-08-04 Paul Jakma <paul@dishone.st>
* ospf_spf.c: (ospf_spf_consider_nexthop) Add comment about issue.

anyway, fixes a reference-listnode-after-delete bug noted by
Kir Kostuchenko.
(ospf_nexthop_calculation) Use ospf_spf_consider_nexthop for all
candidates attached to root.
2004-07-27 Paul Jakma <paul@dishone.st>
* ospf_packet.c: (ospf_ls_upd_send_queue_event) fix thinko from
last fix for ospfd wedging due to oversize LSAs: dont list loop on
ospf_ls_upd_queue_send() - guaranteed segfault.
2004-07-27 Paul Jakma <paul@dishone.st>
* ospf_opaque.c: (ospf_opaque_lsa_flush_schedule) do not NULL out
the LSA as then free_opaque_info_per_id() can never unlock (and
free) the LSA. Reported by Gunnar Stigen.
2004-07-23 Paul Jakma <paul@dishone.st>
* ospf_network.c: Replace PKTINFO/RECVIF with call to
setsockopt_pktinfo

* ospf_packet.c: (ospf_ls_upd_send_queue_event) Partial fix for
problem reported by Peter Frost amongst others, where function
will spin indefinitely if update list contains LSAs greater than
MTU-headers or other condition leading to update list never being
cleared. Problem of what to do with these LSAs remains.

some of the checks up to ospf_read, return either a
virtual link oi, or NULL.
(ospf_read) Cleanup, make it responsible for checks. Remove
the nbr lookup - moved to ospf_neighbor. Adjust all nbr
lookups to use new wrappers exported by ospf_neighbor.
* ospf_neighbor.h: Add ospf_neigbour_get and ospf_nbr_lookup.
* ospf_neighbor.c: (ospf_neigbour_get) Index ospf_interface

(ospf_nbr_lookup) add a wrapper for nbr lookups to deal with
above.
* ospf_interface.c: (ospf_vl_set_params) Catch changes of interface
address for either end of a virtual-link, and hence potential cost
changes.
2004-04-22 Hasso Tepper <hasso@estpak.ee>

to "summarize" routes in ASBR at the moment.
2004-04-20 Hasso Tepper <hasso@estpak.ee>
* ospfd.c: Unset NP flag if area is going to be normal or stub.

Quagga's ospfd in the special situation that a node's opaque
capability has changed as "ON -> OFF -> ON". [quagga-dev 843].
2004-02-19 Sowmini Varadhan <sowmini.varadhan@sun.com>
* ospf_abr.c: (ospf_abr_update_aggregate) UNH 3.12b,c, address range

multicast_memberships bitmask to struct ospf_interface to track
active multicast subscriptions. Declare new function
ospf_if_set_multicast.
* ospf_interface.c: (ospf_if_set_multicast) New function to configure
multicast memberships properly based on the current
multicast_memberships status and the current values of the
ospf_interface state, type, and passive_interface status.

to fix the multicast group memberships.
(ospf_read) When a packet is received on an interface whose state
is ISM_Down, enhance the warning message to show the packet
destination address, and try to update/fix the multicast group
memberships if the packet was sent to a multicast address.
When a packet is received for ospf-designated-routers, but the
current interface state is not DR or BDR, then increase the
severity level of the error message from LOG_INFO to LOG_WARNING,
and try to fix the multicast group memberships.

when deciding if an update will fit.
(ospf_packet_authspace): Factor out calculation of size required
for authentication.

Don't confuse readers that there is a macro.
|
|
* ospf_packet.c: (ospf_db_desc) Reduce severity of "Negotiation done"
messages from LOG_WARNING to LOG_INFO, since this seems to be
normal.
|
|
* ospf_packet.c: (ospf_read) Always look up the interface if
ospf_recv_packet returns NULL ifp, since some platforms such
as Solaris 8 appear to support ifindex retrieval but don't.
|
|
|
|
* ospf_packet.c: (ospf_db_desc) Should be static, not global.
(ospf_hello,ospf_db_desc,ospf_ls_upd,ospf_ls_ack) Improve warning

discarded should give the router id of the neighbor that sent it.
|
|
* global: Replace strerror with safe_strerror. And vtysh/vtysh.c
needs to include "log.h" to pick up the declaration.
|
|
in lib/zebra.h, ensure that RFC3542-required CMSG_SPACE and CMSG_LEN
are defined. Warn if alignment assumptions are made, since they are
i386-centric.
in lib/sockopt.h, declare that sockopt sizes are without
CMSG_SPACE-required padding - just simple sizeof.
in ospfd/ospf_packet.c, simply use CMSG_SPACE
This should remove all instances of CMSG_ALIGN from the source code.
This is a nonstandard, though rational, construct; quagga should use
only those defines in RFC3542.
|
|
* ospf_packet.c: (ospf_write_frags) remove iov arg, msg already points
to it. Add convenience pointer to msg->msg_iov[1], and use this,
fixing the unfortunate borkenness introduced in moving of this code
to a function.

(ospf_ls_upd_packet_new) cast size to long int - unfortunately
glibc's size_t format modifier is not portable.
|
|
* ospf_packet.c: (ospf_ls_upd_packet_new) Format for size_t should
be ld.
* ospf_zebra.c: (ospf_distribute_list_update_timer) Ugly misuse of
THREAD_ARG to store an integer, but it should at least use same
same type to retrieve the value. Assert value is sane.
|
|
* ospf_packet.c: (ospf_write_frags) Add debug output
(ospf_write) set type early, so we can pass it to
ospf_write_frags.
(ospf_ls_upd_packet_new) print size in debug output when too large
packet is encountered.
|
|
* ospfd/ospf_packet.c: setsockopt_pktinfo -> setsockopt_ifindex
* zebra/irdp_main.c: ditto
|
|
* ospf_network.c: (ospf_sock_init) call neutral setsock_ifindex()
function.
* ospf_packet.c: (ospf_read) manually look up ifindex
if system could not have returned one, eg openbsd.
|
|
* (global) Const char update and signed/unsigned fixes.
* (various headers) size defines should be unsigned.
* ospf_interface.h: remove duplicated defines, include the
authoritative header - though, these defines should probably
be moved to a dedicated header, or ospfd.h.
* ospf_lsa.h: (struct lsa) ls_seqnum should be unsigned.
* ospf_packet.c: (ospf_write) cast result of shift to unsigned.
|
|
* ospf_dump.c: (ospf_ip_header_dump) Assume header is in host order
remove ntohs that should have dissappeared. Take struct ip
as argument, caller has to know there's an IP header at start of
stream anyway.
* ospf_dump.h: update declaration of ospf_ip_header_dump.
* ospf_packet.c: (ospf_write) correct call to
sockopt_iphdrincl_swab_htosys which was munging the header.
(ospf_recv_packet) ip_len is needed for old OpenBSD fixup.
(ospf_read) sockopt_iphdrincl_swab_systoh ip header as soon as
we have it.
|
|
|
|
* ospf_packet.c: replace ospf_swap_iph_to... with
sockopt_iphdrincl_swab_...
|
|
* ospf_dump.c: (ospf_ip_header_dump) Use HAVE_IP_HDRINCL_BSD_ORDER
Apply to offset too. Print ip_cksum, lets not worry about
possible 2.0.37 compile problems.
* ospf_packet.c: (ospf_swap_iph_to{n,h}) Use
HAVE_IP_HDRINCL_BSD_ORDER.
(ospf_recv_packet) ditto.
(ospf_write) Fixup iov argument to ospf_write_frags.
|
|
* ospf_packet.c: (ospf_write) (struct msghdr).msg_name is caddr_t
on most platforms.
(ospf_recv_packet) ditto. And msg_flags is not always there
memset struct then set fields we care about rather than
initialise all fields individually.
|
|
|
|
* ospf_packet.c: (ospf_write) ifdef fragmentation support.
move actual fragmentation out to a new, similarly ifdefed, function.
(ospf_write_frags) fragmented write support, moved from previous.
|
|
* ospf_apiserver.{c,h}: lists typedef removal cleanup.
update some list loops to LIST_LOOP. some miscellaneous indent
fixups.
(ospf_apiserver_unregister_opaque_type) fix listnode_delete of
referenced node in loop.
* ospf_interface.h: lists typedef removal cleanup.

|
|
|
* ospf_packet.c: Fix bugzilla #107
(ospf_packet_max) get rid of the magic 88 constant
(ospf_swab_iph_ton) new function. set ip header to network order,
taking BSDisms into account.
(ospf_swab_iph_toh) the inverse.
(ospf_write) Add support for IP fragmentation, will only work on
linux though, other kernels make it impossible. get rid of the
magic 4 constant.
(ospf_make_ls_upd) Bound check to end of stream, not to
interface mtu.
(ospf_ls_upd_packet_new) New function, allocate upd packet
taking oversized LSAs into account.
(ospf_ls_upd_queue_send) use ospf_ls_upd_packet_new to allocate,
rather than statically allocating mtu sized packet buffer, which
actually was wrong - it didnt take ip header into account, which
should not be included in packet buffer.
(ospf_ls_upd_send_queue_event) minor tweaks and remove
TODO comment.

* ospf_network.c: Replace PKTINFO/RECVIF with call to
setsockopt_pktinfo
* ospf_packet.c: Use getsockopt_pktinfo_ifindex and
SOPT_SIZE_CMSG_PKTINFO_IPV4.
|
|
* ospf_packet.c: (ospf_ls_upd_send_queue_event) Partial fix for
problem reported by Peter Frost amongst others, where function
will spin indefinitely if update list contains LSAs greater than
MTU-headers or other condition leading to update list never being
cleared. Problem of what to do with these LSAs remains.
(ospf_make_ls_upd) add comment about large LSA problem,
indentation cleanup.

|
* ospf_packet.c: (ospf_associate_packet_vl) cleanup, move
some of the checks up to ospf_read, return either a
virtual link oi, or NULL.
(ospf_read) Cleanup, make it responsible for checks. Remove
the nbr lookup - moved to ospf_neighbor. Adjust all nbr
lookups to use new wrappers exported by ospf_neighbor.
* ospf_neighbor.h: Add ospf_neigbour_get and ospf_nbr_lookup.
* ospf_neighbor.c: (ospf_neigbour_get) Index ospf_interface
neighbour table by router-id for virtual-link ospf_interfaces,
not by peer_addr (which breaks for asymmetric vlinks)
(ospf_nbr_lookup) add a wrapper for nbr lookups to deal with
above.

* ospf_packet.c: (ospf_recv_packet) OpenBSD now leaves iph.ip_len
network byte order. (bugzilla #67).
