The isis_tilfa_topo1 topotest is comprehensive and contains a large
amount of reference data. One problem is that, when changes occur,
updating this reference data can be difficult.
To address this problem, this commit introduces a method to
automatically regenerate the reference data by setting the `REGEN_DATA`
environment variable.
Usage:
$ REGEN_DATA=true python3 ./test_isis_tilfa_topo1.py
When `REGEN_DATA` is set, the topotest regenerates reference data
from the current run instead of comparing against existing reference
data. Note that regenerated data must be manually verified for
correctness.
This commit also simplifies the reference data by replacing all diff
files with complete JSON snapshots.

In this topotest, steps 10-15 were added to test the IS-IS switchover
functionality. In short, two cases were tested: switchover after a
link down event and switchover after a BFD down event. Both cases
were tested in sequence on the same router, rt6. This involved the
following steps:
- Setting the SPF delay timer to 15 seconds
- Shutting down the eth-rt5 interface from the switch side
- Testing the post-switchover RIB and LIB (triggered by the link down
event)
- Testing the post-SPF RIB and LIB
- Bringing the eth-rt5 interface back up
- Configuring a BFD session between rt6 and rt5
- Shutting down the eth-rt5 interface from the switch side once again
- Testing the post-switchover RIB and LIB (triggered by the BFD down
event)
- Testing the post-SPF RIB and LIB
Since the time window to test the post-switchover RIB and LIB was too
narrow (10 seconds), these tests were having sporadic failures.
To resolve this problem, we can simplify the switchover test as follows:
- Setting the SPF delay timer to 60 seconds (not 15)
- Disabling "link-detect" on rt6's eth-rt5 interface
- Shutting down the eth-rt5 interface from the switch side
- On rt6, testing the post-switchover RIB and LIB (triggered by the
BFD down event)
- On rt5, testing the post-switchover RIB and LIB (triggered by the
link down event)
Notice how we can test both post-link-down and post-BFD-down switchover
cases simultaneously by having different "link-detect" configurations
on rt5 and rt6. Additionally, by using a larger SPF delay timer, the
time window to test the post-switchover RIB and LIB is much larger
and less prone to sporadic failures.

When displaying a route table in JSON, a table JSON object is storing
all the prefix JSON objects containing the prefix information. This
results in excessive memory allocation for JSON objects, potentially
leading to an out-of-memory error on the machine with large routing

Description:
OSPF6 GR HELPER router should consider as TOPOCHANGE when
it receives lsas with max age and should exit from Helper.
But, it is not exiting from helper because this max age lsa is
considered as duplicated lsa since the sender uses same seq
number for max age lsa from the previous lsa update.
Currently, topo change is not considered for duplicated lsas.
So removed the duplicated check when validating TOPOCHNAGE.

After modifying the "label vpn export value", the vpn label information
of the VRF is not updated to the peers.
For example, the 192.168.0.0/24 prefix is announced to the peer with a
label value of 222.
> router bgp 65500
> [..]
> neighbor 192.0.2.2 remote-as 65501
> address-family ipv4-vpn
> neighbor 192.0.2.2 activate
> exit-address-family
> exit
> router bgp 65500 vrf vrf2
> address-family ipv4 unicast
> network 192.168.0.0/24
> label vpn export 222
> rd vpn export 444:444
> rt vpn both 53:100
> export vpn
> import vpn
> exit-address-family
Changing the label with "label vpn export" does not update the label
value to the peer unless the BGP sessions is re-established.
No labels are stored are stored struct bgp_adj_out so that it is
impossible to compare the current value with the previous value
in adj-RIB-out.
Reference the bgp_labels pointer in struct bgp_adj_out and compare the
values when updating adj-RIB-out.

In a BGP L3VPN context using ADJ-RIB-IN (ie. enabled with
'soft-reconfiguration inbound'), after applying a deny route-map and
removing it, the remote MPLS label information is lost. As a result, BGP
is unable to re-install the related routes in the RIB.
For example,
> router bgp 65500
> [..]
> neighbor 192.0.2.2 remote-as 65501
> address-family ipv4 vpn
> neighbor 192.0.2.2 activate
> neighbor 192.0.2.2 soft-reconfiguration inbound
The 192.168.0.0/24 prefix has a remote label value of 102 in the BGP
RIB.
> # show bgp ipv4 vpn 192.168.0.0/24
> BGP routing table entry for 444:1:192.168.0.0/24, version 2
> [..]
> 192.168.0.0 from 192.0.2.2
> Origin incomplete, metric 0, valid, external, best (First path received)
> Extended Community: RT:52:100
> Remote label: 102
A route-map now filter all incoming BGP updates:
> route-map rmap deny 1
> router bgp 65500
> address-family ipv4 vpn
> neighbor 192.0.2.2 route-map rmap in
The prefix is now filtered:
> # show bgp ipv4 vpn 192.168.0.0/24
> #
The route-map is detached:
> router bgp 65500
> address-family ipv4 vpn
> no neighbor 192.168.0.1 route-map rmap in
The BGP RIB entry is present but the remote label is lost:
> # show bgp ipv4 vpn 192.168.0.0/24
> BGP routing table entry for 444:1:192.168.0.0/24, version 2
> [..]
> 192.168.0.0 from 192.0.2.2
> Origin incomplete, metric 0, valid, external, best (First path received)
> Extended Community: RT:52:100
The reason for the loose is that labels are stored within struct attr ->
struct extra -> struct bgp_labels but not in the struct bgp_adj_in.
Reference the bgp_labels pointer in struct bgp_adj_in and use its values
when doing a soft reconfiguration of the BGP table.

The test is done on r2. A BGP update is received on r2, and is
filtered on r2. The RIB of r2 does not have the BGP update stored,
but the ADJ-RIB-IN is yet present. To demonstrate this, if the
inbound route-map is removed, then the BGP update should be copied
from the the ADJ-RIB-IN and added to the RIB with the label

The handling of MPLS labels in BGP faces an issue due to the way labels
are stored in memory. They are stored in bgp_path_info but not in
bgp_adj_in and bgp_adj_out structures. As a consequence, some
configuration changes result in losing labels or even a bgpd crash. For
example, when retrieving routes from the Adj-RIB-in table
("soft-reconfiguration inbound" enabled), labels are missing.
bgp_path_info stores the MPLS labels, as shown below:
> struct bgp_path_info {
> struct bgp_path_info_extra *extra;
> [...]
> struct bgp_path_info_extra {
> mpls_label_t label[BGP_MAX_LABELS];
> uint32_t num_labels;
> [...]
To solve those issues, a solution would be to set label data to the
bgp_adj_in and bgp_adj_out structures in addition to the
bgp_path_info_extra structure. The idea is to reference a common label
pointer in all these three structures. And to store the data in a hash
list in order to save memory.
However, an issue in the code prevents us from setting clean data
without a rework. The extra->num_labels field, which is intended to
indicate the number of labels in extra->label[], is not reliably checked
or set. The code often incorrectly assumes that if the extra pointer is
present, then a label must also be present, leading to direct access to
extra->label[] without verifying extra->num_labels. This assumption
usually works because extra->label[0] is set to MPLS_INVALID_LABEL when
a new bgp_path_info_extra is created, but it is technically incorrect.
Cleanup the label code by setting num_labels each time values are set in
extra->label[] and checking extra->num_labels before accessing the
labels.

TL;DR; When we configure `advertise-all-vni` (in this case), a new BGP instance
is created with the name vrf100, and ASN 50. Next, when we create
`router bgp 100 vrf vrf100`, we look for the BGP instance with the same name
and we found it, but ASNs are different 50 vs. 100.
Every such a new auto created instance is flagged with BGP_VRF_AUTO.
After the fix:
```
router bgp 50
!
address-family l2vpn evpn
advertise-all-vni
exit-address-family
exit
!
router bgp 100 vrf vrf100
exit
!
end
donatas.net(config)# router bgp 51
BGP is already running; AS is 50
donatas.net(config)# router bgp 50
donatas.net(config-router)# router bgp 101 vrf vrf100
BGP is already running; AS is 100
donatas.net(config)# router bgp 100 vrf vrf100
donatas.net(config-router)#
```

Fixes:
zebra/zebra_netns_notify.c: In function 'zebra_ns_ready_read':
zebra/zebra_netns_notify.c:266:40: error: implicit declaration of function 'basename' [-Wimplicit-function-declaration]
266 | if (strmatch(VRF_DEFAULT_NAME, basename(netnspath))) {
| ^~~~~~~~
Fixed by including libgen.h, then since basename may modify its
parameter, allocate a copy on the stack, using strdupa, and pass the
temporary string to basename.
According to the man page for basename:
With glibc, one gets the POSIX version of basename() when
<libgen.h> is included, and the GNU version otherwise.
The POSIX version of basename may modify the contents of path,
so we should to pass a copy when calling this function.

I had problem by running container after build.
It gave the error below in container,
[FATAL tini (7)] exec /usr/lib/frr/docker-start failed: Permission denied
So I have fixed the permission issues after building images.

The 'show running-config' does not display the ipv6 source address
when a locator is not configured. Fix this by systematically displaying
the ipv6 source address.

This change will stop this action from running on forked repos.
Previously whenever one pushed a change to one's development branch the
action would "run but skip" which still generated an email notifications
and thus was very annoying. :)

The default DSCP used for BGP connections is CS6. The DSCP value is
not part of the TCP header.
When setting the IP_TOS or IPV6_TCLASS socket options, the argument
is not the 6-bit DSCP value, but an 8-bit value for the former IPv4
Type of Service field or IPv6 Traffic Class field, respectively.
