Timotej Lazar 25bcddede1 Factor frr role from debian, ceph and proxmox 
Consolidate base system and networking setup into debian role and BGP
configuration into frr role. Add facts role to collect data from NetBox
once to avoid many slow lookups. Also many other tweaks and cleanups.

Timotej Lazar be915dcf69 proxmox: only install firewall rules on one node 
And let the cluster take care of distribution.

Timotej Lazar 3f53c84865 proxmox: add LDAP user sync script 
Since OIDC auth doesn’t support groups, get them from AD over LDAP.

Add a script to fetch user and groups, and update /etc/pve/user.cfg. The
script is only installed on one node (first alphabetically), with a cron
job to run it daily.

The script is installed for clusters with the sync-ldap context key set
to a corresponding OIDC realm. The keys ldap_user and ldap_pass must be
present in the password store under cluster/<name>.

Timotej Lazar 5762236ac2 ceph: fix nftables management rule 
The mgmt VRF might not exist yet when nftables rules are loaded, so
use iifname instead of iif for dynamic interface lookup.

Timotej Lazar 5a7fa02909 proxmox: don’t route host traffic over VNIs 
Very bad, much slow.

Timotej Lazar a637da5c21 proxmox: set vxlan-local-tunnelip for loopback interface 
Oops. Not sure why stuff apparently worked without it. Especially
switchd on exits which worked itself into a bit of a frenzy.

Timotej Lazar 923d877208 proxmox: use inner L3 info for ECMP hashing 
I’m sure I saw fib_multipath_hash_policy=2 (or =1 from last commit)
actually working once, but cannot reproduce. Maybe revisit this at
some point.
 2024-04-08 08:49:16 +02:00
Timotej Lazar f404922d6b proxmox: use L4 info for ECMP hashing 
This should make VXLAN-encapsulated traffic multipath.

Timotej Lazar 8be55c2bde ceph: set up firewall 
Still need to drop the hardcoded allowed set.
 2024-04-05 06:12:58 +02:00
Timotej Lazar e7f9132571 proxmox: set up firewall 
Firewall policy is set in NetBox as cluster services¹. For Proxmox we
have to manually allow communication between nodes when using L3,
since the default management ipset does not get populated correctly.
We also need to open VTEP communication between nodes, which the
default rules don’t. We allow all inter-node traffic, as SSH without
passwords must be permitted anyway.

This also adds some helper filters that are spectacularly annoying to
implement purely in templates.

¹ There is actually no such thing as as a cluster service (yet?), so
instead we create a fake VM for the cluster, define services for it,
and then add the same services to a custom field on the cluster.
Alternative would be to tie services to a specific node, but that
could be problematic if that node is replaced.

Timotej Lazar ce7903e43a ceph: improve cluster setup 
Remove separate NetBox lookups. Explicitly allow connections between
cluster nodes. Tigthen temporary allowed IPv6 ranges.

Timotej Lazar 7b4cb8f579 Add udev rules for renaming all interfaces with defined MAC address 
Gonna include BMC and such but shouldn’t hurt. Allows us to use
different interface names where sensible.

Timotej Lazar fbfdc83ee5 proxmox: use multiple non-VLAN-aware bridges 
The Proxmox SDN feature does not play nice with our FRR and VXLAN setup.
With a single bridge we can’t have interface aliases. So use a bridge
for each VLAN. Actually don’t even have VLANs, just bridges mainlined
into VXLAN tunnels.

Read the list of VLANs carried by Proxmox nodes from a custom field on
the cluster in NetBox. Remove the vmbr0 device from individual nodes.
