OPENVPN: T6555: add server-bridge options in mode server
|
|
T5873: T6619: remove unused imports
|

* Only matching flags and fields used by modern RFC2890 "extended GRE" -
this is backwards-compatible, but does not match all possible flags.
* There are no nftables helpers for the GRE key field, which is critical
to match individual tunnel sessions (more detail in the forum post)
* nft expression syntax is not flexible enough for multiple field
matches in a single rule and the key offset changes depending on flags.
* Thus, clumsy compromise in requiring an explicit match on the "checksum"
flag if a key is present, so we know where key will be. In most cases,
nobody uses the checksum, but assuming it to be off or automatically
adding a "not checksum" match unless told otherwise would be confusing
* The automatic "flags key" check when specifying a key doesn't have similar
validation, I added it first and it makes sense. I would still like
to find a workaround to the "checksum" offset problem.
* If we could add 2 rules from 1 config definition, we could match
both cases with appropriate offsets, but this would break existing
FW generation logic, logging, etc.
* Added a "test_gre_match" smoketest

T6632: add missing standard functions to config scripts
|
|
T6629: call check_kmod within a standard config function
|
|
|
|
In the PR https://github.com/vyos/vyos-1x/pull/3823 the ncp-ciphers
were replaced with `data-ciphers`
fix template for "generate openvpn client-config"
|
|
|
|
|
|
|
|
Move the remaining calls to check_kmod within a standard function,
with placement determined by the needs of the config script.

nat64: T6627: call check_kmod within standard config function
|
|
Functions called from config scripts outside of the standard functions
get_config/verify/generate/apply will not be called when run under
configd. Move as appropriate for the general config script structure and
the specific script requirements.

system: op-mode: T3334: allow delayed getty restart when configuring serial ports
|
|
ports
* Created op-mode command "restart serial console"
* Relocated service control to vyos.utils.serial helpers, used by conf- and
op-mode serial console handling
* Checking for logged-in serial sessions that may be affected by getty reconfig
* Warning the user when changes are committed and serial sessions are active,
otherwise restart services as normal. No prompts issued during commit,
all config gen/commit steps still occur except for the service restarts
(everything remains consistent)
* To apply committed changes, user will need to run "restart serial console"
to complete the process or reboot the whole router
* Added additional flags and target filtering for generic use of helpers.

vrf: T6603: conntrack ct_iface_map must only contain one entry for iifname/oifname
|
|
|
|
Commit 452068ce78 ("interfaces: T6592: moving an interface between VRF instances
failed") added a similar but more detailed implementation of get_vrf_table_id()
that was added in commit adeac78ed of this PR. Move to the common available
implementation.
|
|
* PBR can only target table IDs up to 200 and the previous PR to extend the
range was rejected
* PBR with this PR can now also target VRFs directly by name, working around
targeting problems for VRF table IDs outside the overlapping 100-200 range
* Validation ensures rules can't target both a table ID and a VRF name
(internally they are handled the same)
* Added a simple accessor (get_vrf_table_id) for runtime mapping a VRF name
to table ID, based on vyos.ifconfig.interface._set_vrf_ct_zone().
It does not replace that usage, as it deliberately does not handle non-VRF
interface lookups (would fail with a KeyError).
* Added route table ID lookup dict, global route table and VRF table defs
to vyos.defaults. Table ID references have been updated in code touched
by this PR.
* Added a simple smoketest to validate 'set vrf' usage in PBR rules

and return an empty list in that case
(handy for migration scripts and the like)

T6362: Create conntrack logger daemon
|
|
OpenVPN CLI-option: T6571: rename ncp-ciphers with data-ciphers
|
|
This patch on #3616 will only attempt to fix ipsec matches in rules if the
firewall config tree passed to migrate_chain() has rules attached.
|
|
Strongswan does not initiate session after termination via vici.
Added an CHILD SAs initialization on the initiator side
of the tunnel.
|
|
(#3616)
* Change ipsec match-ipsec/none to match-ipsec-in and match-none-in for
fw rules
* Add ipsec match-ipsec-out and match-none-out
* Change all the points where the match-ipsec.xml.i include was used
before, making sure the new includes (match-ipsec-in/out.xml.i) are
used appropriately. There were a handful of spots where match-ipsec.xml.i
had snuck back in for output hooked chains already
(the common-rule-* includes)
* Add the -out generators to rendered templates
* Heavy modification to firewall config validators:
* I needed to check for ipsec-in matches no matter how deeply nested
under an output-hook chain(via jump-target) - this always generates
an error.
* Ended up retrofitting the jump-targets validator from root chains
and for named custom chains. It checks for recursive loops and improper
IPsec matches.
* Added "test_ipsec_metadata_match" and "test_cyclic_jump_validation"

iifname/oifname
When any of the following features NAT, NAT66 or Firewall is enabled, for every
VRF on the CLI we install one rule into nftables for conntrack:
chain vrf_zones_ct_in {
type filter hook prerouting priority raw; policy accept;
counter packets 3113 bytes 32227 ct original zone set iifname map @ct_iface_map
counter packets 8550 bytes 80739 ct original zone set iifname map @ct_iface_map
counter packets 5644 bytes 67697 ct original zone set iifname map @ct_iface_map
}
This is superfluous.
