pmacct daemons have one very important specific - they handle control signals in
the same loop as packets. And packets waiting is blocking operation.
Because of this, when systemctl sends SIGTERM to uacctd, this signal has no
effect until uacct receives at least one packet via nflog. In some cases, this
leads to a 90-second timeout, sending SIGKILL, and improperly finished tasks.
As a result, a working folder is not cleaned properly.
This commit contains several changes to fix service issues:
- add a new nftables table for pmacct with a single rule to get the ability to
send a packet to nflog and unlock uacctd
- remove PID file options from the uacctd and a systemd service file. Systemd
can detect proper PID, and PIDfile is created by uacctd too late, which leads
to extra errors in systemd logs
- KillMode changed to mixed. Without this, SIGTERM is sent to all plugins and
the core process exits with status 1 because it loses connection to plugins too
early. As a result, we have errors in logs, and the systemd service is in a
failed state.
- added logging to uacctd
- systemctl service modified to send packets to specific address during a service
stop which unlocks uacctd and allows systemctl to finish its work properly

Calling system-login.py with no mounted VyOS config has the negative effect
that the script will not detect any local useraccounts and thus assumes they
all need to be removed from the password backend.
As soon as the VyOS configuration is mounted and the CLI content is processed,
system-login.py get's invoked and re-creates the before deleted user accounts.
As the account names are sorted in alphabetical order, the name <-> UID mapping
can get mixed up during system reboot.
The intention behind calling system-login.py from vyos-router init was to
reset system services (PAM, NSS) back to sane defaults with the defaults
provided via system-login.py. As PAM is already reset in vyos-router startup
script, /etc/nsswitch.conf was the only candidate left.
This is now accomplished by simply creating a standard NSS configuration file
tailored for local system accounts.
This is the second revision after the first change via commit 64d32329958
("login: T5521: home directory owner changed during reboot") got reverted.

This reverts commit 074870dad33d80e78128736f9e89bdfa1a0e08fd.
|
|
During system startup the system-login.py script is invoked by vyos-router
systemd service. As there is no complete configuration available at this
point in time - and the sole purpose of this call is to reset/re-render
the system NSS/PAM configs back to default - it accidently also deleted the
local useraccounts.
Once the VyOS configuration got mounted, users got recreated in alphabetical
order and thus UIDs flipped and the /home suddenely belonged to a different
account.
This commit prevents any mangling with the local userdatabase during VyOS
bootup phase.

This commit adds a new configuration option to the mDNS repeater service
to allow controlling which IP version to use for mDNS repeater.
Additionally, publishing AAAA record over IPv4 and A record over IPv6 is
disabled as suggested.

init: T5239: configure system hostname prior to FRR startup (backport #2289)
|
|
(cherry picked from commit 4bbbaab60d56bfd6f3a145378027642b4c47adee)
|
|
On first boot after an upgrade /etc/hostname and FRR configuration is not
populated. FRR determines the system hostname once during startup and does not
repect changes of the hostname CLI value.
Thus after an upgrade of VyOS FRR started with a hostname of debian that was
propagated to peers.
The commit retrieves the hostname from the CLI and presets this before FRR is
initially started.

AgentX does not work stable. From time to time we see the system
service crashing/degrading if something is wrong with SNMP from
util net-snmp.
We should disable it by default and enable it only if configured.

After commit 976f82785 ("T5575: ARP/NDP table-size isnt set properly") the
system bootup process got interrupted as both system-ip.py and system-ipv6.py
tried to talk to FRR which was yet not started.
This has been fixed by using a conditional path to only execute when FRR service
has been enabled. This is safe to do as the initial commit call will has FRR
service running and the path will be executed.

T5480: Ability to disable SNMP for keepalived service VRRP
|
|
- Reuse existing utility functions to check if a boot is ongoing
(boot_configuration_complete())
- Run system_frr.py script to configure FRR daemon before initial launch
- Add safety net to always have FRR running on the system
This does yet not solve the error in T5239 but it's a small step towards
the solution.

FRR supports a new way of configuring VLAN-to-VNI mappings for EVPN-VXLAN, when
working with the Linux kernel. In this new way, the mapping of a VLAN to a VNI
is configured against a container VXLAN interface which is referred to as a
'Single VXLAN device (SVD)'.
Multiple VLAN to VNI mappings can be configured against the same SVD. This
allows for a significant scaling of the number of VNIs since a separate VXLAN
interface is no longer required for each VNI.
Sample configuration of SVD with VLAN to VNI mappings is shown below.
set interfaces bridge br0 member interface vxlan0
set interfaces vxlan vxlan0 external
set interfaces vxlan vxlan0 source-interface 'dum0'
set interfaces vxlan vxlan0 vlan-to-vni 10 vni '10010'
set interfaces vxlan vxlan0 vlan-to-vni 11 vni '10011'
set interfaces vxlan vxlan0 vlan-to-vni 30 vni '10030'
set interfaces vxlan vxlan0 vlan-to-vni 31 vni '10031'
