VPP: T1797: Added interfaces reinitialization
|
|
After an interface is added/removed from VPP, it will be reinitialized, which
allows reconfiguring IP addresses on it.
Also modified VPP load priority to start before interfaces, and avoid
reconfiguration during boot.
|

We cannot use some specific names like POSTROUTING/PREROUTING
as for PBR they overlaps with VyOS defined chains
Chains aftoconfigured by VyOS itself:
chain VYOS_PBR_PREROUTING
chain VYOS_PBR_POSTROUTING
If we try to use chain name "POSTROUTING" it generates 2 chains
with the same name "chain VYOS_PBR_POSTROUTING" one is
autoconfigured and the second defined by user
set policy route POSTROUTING rule 100
Add the user-defined (UD) prefix to separate user defined names
That allows to use any user-defined names

T5048: QoS do not add prio if it is already in tc command
|
|
Prevent duplicatte prio fot tc command
|
|
T5332: Fix show policy route without attahed interface
|
|
Interface may not be present in the op-mode dictionary, it cause
KeyError: 'interface' for policy route
|
|
T5048: QoS index priority should be used only for shaper
|
|
QoS index priority should be used only for qostype 'shaper'
otherwise we set priority 2 times, that is incorrect.
OSError: [Errno 255] failed to run command:
tc filter add dev eth2 parent 1: prio 5 protocol all prio 1 u32 match ip src 10.1.1.0/24 flowid 1:1e
exit code: 255
Fix it

T5295: QoS fix policy limiter tc filter rate limit
|
|
Fix QoS tc class with multiple matches generates one rule but
expects multiple filter rules:
set qos policy shaper test class 23 match one ip protocol 'tcp'
set qos policy shaper test class 23 match two ip protocol 'udp'
tc filter add dev eth0 parent 1: protocol all prio 1 u32 match ip protocol 6 0xff flowid 1:17
tc filter add dev eth0 parent 1: protocol all prio 2 u32 match ip protocol 17 0xff flowid 1:17
|
|
tc filter rate limit should be used only if qostype is 'limiter'
and not 'shaper'

T1797: VPP verify minimal installed memory and apply sysctl
|
|
Do not allow configure VPP if on the systems with low amount
installed memory
Add sysctl VPP parameters (hugepages, kernel.shmmax)

T5329 : priority: tunnel config is committed before wireguard

Service config-sync allows synchronizing a section of
the configuration.
As PoC allow only nat, nat66 and firewall sections
Rertreive the configuration for a section from self node and
send this configuration to the section of the 'secondary' node.
This feature adds a symlink from helper 'vyos_config_sync.py'
to '/config/scripts/commit/post-hooks.d' and config that is
located in '/run/config_sync_conf.conf'
It will synchronyze the config only if the setcion
was changed.
set service config-sync secondary address 192.0.2.11
set service config-sync secondary key xxx
set service config-sync section nat
set service config-sync section nat66
set service config-sync section firewall
set service config-sync mode load

T1797: Add initial vpp configuration
|
|
|
|
VPP: T1797: Optimized interfaces add/remove
|
|
- added extra renaming operation to be sure that interface has the same name as
before in the system after it was moved from VPP to kernel
- added extra check after PCI device removal/adding
- added check for proper `retval` for CPI calls where it is available
- replaced empty return with an error in `_get_pci_address_by_interface()`
because not resolved address will lead to inconsistency of the system later
|
|
The previous implementation did not iterate over the communit list, so only
one match criteria was supported.
set policy route-map FOO rule 10 action 'permit'
set policy route-map FOO rule 10 set extcommunity rt '1111:2222222'
worked but on the other hand this failed:
set policy route-map FOO rule 20 action 'permit'
set policy route-map FOO rule 20 set extcommunity rt '6500:24 6500:23 192.168.0.1:111 192.168.0.1:222'

T5320: warn on entering config mode if boot config errors present

VPP: T1797: Improved PCI address search
|
|
- added ability to add/remove interfaces without system reboot
- added `attempts` and `interval` to the VPP API connection. This is helpful in
case of high system load or when VPP was just started and API is not yet
available.
- added exceptions to API calls. This allows handling errors in communication
with API properly in conf-mode scripts.
- fixed PCI address search in VPP to match Linux kernel and ethtool style
- fixed systemd daemons control - first reload, then restart
- removed debug prints
- removed `vm.nr_hugepages` configuration. It is not required now but increases
RAM requirements a lot.
|
|
Use info from both ethtool and VPP to find PCI address for an
interface.

|
T5304: Container add volume bind propagation option
|
|
|
|
Replaced CLI commands with API calls.
CLI commands still can be used via:
```
vpp_control = VPPControl()
vpp_control.cli_cmd('command_here')
```
|
|
set container name c1 volume myvlm propagation rshared
|
|
Add initial configuration mode for VPP (PoC)
set vpp cpu corelist-workers '2'
set vpp cpu main-core '1'
set vpp interface eth1 num-rx-desc '256'
set vpp interface eth1 num-rx-queues '512'
set vpp interface eth1 num-tx-desc '256'
set vpp interface eth1 num-tx-queues '512'
set vpp interface eth1 pci '0000:02:00.0'
set vpp interface eth1 rx-mode 'polling'
set vpp interface eth2 pci '0000:08:00.0'
Limitation:
- 'set vpp interface ethX pci auto' works only per first
commit, then interface detached from default stack and creates
tun interface 'ethX' to communicate with default stack. In this
case we can't get PCI address via ethtool for 'tun' interfaces.
But we can set pci address manualy.
- Interface sync between default stack and VPP-DPDK stack
After vpp change it doesn't trigger iproute2 for changes
(should be written later)
I.e. if we change something in vpp per each commit it restarts
vpp.service it gets empty interface config as we don't configure vpp
directly and it should be configured via iproute2
But then if we do any change on interface (for example description)
it gets IP address, MTU, state, etc.

config: T5228: simplify get_config_dict and add argument with_defaults
|
|
vyos.configdict: T5308: Remove workarounds for incorrect defaults in get_interface_dict
|
|
T5312: Escape special character
|
|
|
|
The original implementation of defaults, and workaround required, would
leave an entry {'dhcpv6_options': {'pd': {}}} in the interface_dict.
|
|
|
|
For those cases not covered by automatic merging of defaults in
get_config_dict(..., with_defaults=True), get_config_defaults should
take arguments consistent with those of get_config_dict, for ease of
merging results.
