When sending down a babel route do not remove then
add it back. Just send down the change. This
change will not cause packets to be dropped now.

Babel was thinking it was talking to the kernel for
route installation instead of zebra. Pass down the

Create a single registry of default port values that daemons
are using. Most of these are vty ports, but there are some
others for features like ospfapi and zebra FPM.

clang-format doesn't understand FRR_DAEMON_INFO is a long macro where
laying out items semantically makes sense.
(Also use only one `FRR_DAEMON_INFO(` in isisd so editors don't get
confused with the mismatching `( ( )`.

Replace `struct list *` with `DLIST(if_connected, ...)`.
NB: while converting this, I found multiple places using connected
prefixes assuming they were IPv4 without checking:
- vrrpd/vrrp.c: vrrp_socket()
- zebra/irdp_interface.c: irdp_get_prefix(), irdp_if_start(),
irdp_advert_off()
(these fixes are really hard to split off into separate commits as that
would require going back and reapplying the change but with the old list
handling)

Ensure proper memory cleanup by freeing the `babel_ifp->ipv4` when
babel interface is deleted. This prevents memory leaks.

Release memory allocated for the IPv4 address during the interface reset.
The addition of `free(babel_ifp->ipv4)` ensures proper cleanup, preventing
potential memory leaks.

babeld: add AE!=0 check when type is 7 or 10.
|
|
When running all daemons with config for most of them, FRR has
sharpd@janelle:~/frr$ vtysh -c "show debug hashtable" | grep "VRF BIT HASH" | wc -l
3570
3570 hashes for bitmaps associated with the vrf. This is a very
large number of hashes. Let's do two things:
a) Reduce the created size of the actually created hashes to 2
instead of 32.
b) Delay generation of the hash *until* a set operation happens.
As that no hash directly implies a unset value if/when checked.
This reduces the number of hashes to 61 in my setup for normal
operation.

This is a first in a series of commits, whose goal is to rename
the thread system in FRR to an event system. There is a continual
problem where people are confusing `struct thread` with a true
pthread. In reality, our entire thread.c is an event system.
In this commit rename the thread.[ch] files to event.[ch].

When listening on a multicast group. No need to actually
fail the operation when it's already being used.
Let's not treat the Address already in use error message
as one that is stopping everything from working. Especially
since multiple interface events cause this to happen.
Without this, if config is read in before full connection
to zebra, babel will never establish neighbors.

Rather than running selected source files through the preprocessor and a
bunch of perl regex'ing to get the list of all DEFUNs, use the data
collected in frr.xref.
This not only eliminates issues we've been having with preprocessor
failures due to nonexistent header files, but is also much faster.
Where extract.pl would take 5s, this now finishes in 0.2s. And since
this is a non-parallelizable build step towards the end of the build
(dependent on a lot of other things being done already), the speedup is
actually noticeable.
Also files containing CLI no longer need to be listed in `vtysh_scan`
since the .xref data covers everything. `#ifndef VTYSH_EXTRACT_PL`
checks are equally obsolete.
