* ospf_spf.h: Add backlink field to struct vertex
* ospf_spf.h: (ospf_vertex_new) initialise backlink
(ospf_lsa_has_link) return index of link back to
vertex V from candidate vertex W, or -1 if no link exists.
(ospf_spf_next) save backlink index for candidate vertex
* ospf_interface.c: (ospf_vl_set_params) Use the backlink index
to determine correct address for virtual-link peers. Fall back
to older "pick first link" method if no backlink index exists.

|
* ospf_zebra.c: (ospf_interface_delete) Do not delete the interface
params, nor the interface structure, if an interface delete
message is received from zebra.
* ospf_interface.c: (ospf_if_delete_hook) Delete the interface
params and interface, ie that which was previously removed in
(ospf_interface_delete) above.

more. I'm not sure if this read should be attempted at all, but I'm trying
to keep code safe AND stable.

|
* ospfd/ospf_interface.c: (ospf_if_table_lookup) grab reference to
rn->info /before/ calling route_unlock_node() as some systems
may deliberately poison freed memory, eg FreeBSD 5.1.
see [quagga-dev 417].
|
|
* ospfd/ospf_interface: (ospf_if_lookup_table) fix compile errors
from previous patch. doh.
|
|
* ospfd/ospf_interface: (ospf_if_lookup_table) new function to
lookup oi for a given prefix in a given interfaces table of oi's.
(ospf_if_new) use ospf_if_lookup_table to deal with zebra
reporting new interface multiple times.
NB: This patch is a complete plaster-band of a hack. First, why is
zebra reporting interface events multiple times? Second, why does
ospfd maintain so many damn lists and tables relating to oi's -
these should be reconciled into one or two tables.
|
|
* lib/if.c: (if_cmp_func) new function, compare interface names in
alphabetical order.
(if_create) Take name as argument and add interface in sorted order.
(if_get_by_name),(interface_cmd) fixup calls to if_create - see
above.
(if_init) register list comparison function.
* lib/if.h: Add comparison function, modify if_create prototype.
* lib/zclient.c: Modify call to if_create.
* ospfd/ospf_interface.c: (ospf_vl_new) modify call to if_create.
change sprintf to snprintf.
* zebra/kernel_socket.c: (ifm_read) modify call to if_create.

|
* ospf_interface.c (ospf_vl_set_params): new router LSA is not
generated when the cost of the routing entry for the virtual
link endpoint has changed. If the cost to reach the virtual link's
endpoint has changed, add router LSA timer for the backbone area.

* Revert Cougar's sort interface names patch, causes problems with
enabling of interfaces for OSPF in ospfd.

Subject: [zebra 19263] Another memory leak!! is zebra OSPF
This memory leak gets into picture whenever any interface goes down.
Problem found and desctription: Whenever the interface goes down, the
"def_params" (member of ospf_if_info) structure memory is not freed.
Fix made: added the following line to free the "def_params" memory of
ospf_if_info before calling the "XFREE(MTYPE_OSPF_IF_INFO, ifp->info);"
The added line is:
ospf_del_if_params ((struct ospf_if_params *) IF_DEF_PARAMS (ifp));

Subject: [zebra 19262] Re: Memory leak in OSPF
Fix applied for Kamatchi's original report was to remove the auth_crypt
initialisation from the wrong function. This should fix that.

Subject: [zebra 19259] Memory leak in OSPF
The detail of the memory leak follows:
File name: ospf_interface.c
Function name: ospf_if_new_hook().
Type of leak: Overwriting the already allocated memory.
Problem found and description:
The ospf_new_if_params() fn allocates a memory for "auth_crypt" which
is overwritten, down in the fn (ospf_if_new_hook) by explicitely allocating
a memory for the same "auth_crypt".
Fix: remove allocation from ospf_new_if_params()

* ospf_interface.c(ospf_if_lookup_recv_if): Use the most specific
match for interface lookup.

Subject: [zebra 18767] possible SIGSEGV
Fix incorrect memset

* Sync to Zebra CVS
* Fix lib/thread.h leak
* Fix small Opaque LSA leak
* Do not configure OSPF interfaces for secondary addresses
* vtysh fixes from Hasso
* Dave Watson's missing ntohs fix
|
|
|
|
* sync to latest zebra CVS
* spec file: updated and added define for ospf-api/client
NB: OSPF-API has been broken by the zebra.org changes, which
has added struct ospf * as a new arg to many functions

may return an existing node. (if the code wants a /new/ node why not use
route_node_set? if it doesnt mind - then the assert is wrong).
this bug is in zebra.org CVS. (must be an extremely rare/unlikely bug
though).
