The dplane_ctx_get_pbr_ipset_entry function only
failed when the caller did not pass in a valid
usable pointer. Change the code to assert on
a pointer not being passed in and remove the
bool return

The only time this function ever failed is when
the developer does not pass in a usable pointer
to place the data in. Change it to an assert
to signify to the end developer that is what
we want and then remove all the if checks
for failure

The function call dplane_ctx_get_pbr_ipset only
returns false when the calling function fails to
pass in a valid ipset pointer. This should
be an assertion issue since it's a programming
issue as opposed to an actual run time issue.
Change the function call parameter to not return
a bool on success/fail for a compile time decision.

rp-count==0 isn't a broken BSM, it just means the BSR no longer has any
Candidate RPs for the group range. Previous behavior is badly mistaken
since it stops processing the entire packet.
Fix to correctly remove group range on rp-count==0 and continue
processing remainder of the packet.

This is implicitly checked by the "verify mroute" below, but it's much
more helpful to explicitly check in advance.

NHT won't have a result yet when we get the first BSM from a new BSR.
Hence, the first packet(s) are lost, since their RPF validation fails.
Re-add the blocking RPF check that was there before (though in a much
more sensible manner.)
Also nuke the now-unused pim_nexthop_match* functions.

The Bootstrap message RX path needs a RPF check for the BSR address,
and this is implemented both incorrectly as well as quite ugly.
Clean up and fix case when we have multiple interfaces to the same LAN
and/or ECMP nexthops (both would cause message duplication, the former
can even cause BSM forwarding loops.)

Most users of if_lookup_address_exact only cared about whether the
address is any local address. Split that off into a separate function.
For the users that actually need the ifp - which I'm about to add a few
of - change it to prefer returning interfaces that are UP.
(Function name changed due to slight change in behavior re. UP state, to
avoid possible bugs from this change.)

During shutdown, when table_manager_disable is called for the default
VRF, its vrf_id is already set to VRF_UNKNOWN, so the expression is true
and the table manager memory is not freed. Change the expression to
compare the VRF name instead of the id. The check in table_manager_enable
is changed for consistency.

Function ospf_te_parse_te() and ospf_te_delete_te() browse TE TLV but also
subTLV. The loop that parse the subTLV check that cummulative read data doesn't
exceed the total size of the TLV. However, the sum variable that counts the
number of read data was wrongly intialize to 0 instead to 4 (i.e. the initial
TLV Header size that is located at the TOP of subTLV).
This patch adjust accordingly the initial value of the counter.

The no-form should use the same arguments as the regular command, hence
replace "period" with "grace-period".

There was a historical blurb at the top of the process architecture
document that in several instances caused some confusion regarding
whether or not FRR supports multithreading. Remove this paragraph and

Currently I get bgp_instance_del-test as well as bgp_l3vpn_to_bgp_vrf
failures every ~3-4 runs when under a 40 parallel run with micronet.
Examination of the failure and passing cases always leads to the
failures showing convergence of bgp bestpath immediately after
the show commands to ensure that the routes are there.
Modify the code to look for the fact that the vrf has
converged from routes being passed around across vrf's
and ensure that bestpath has run on them.

When "update-source IFNAME" is used for the neighbor, p->update_source
