T4889: NAT Redirect: adddestination nat redirection (to local host) feature.
|
|
|
|
The fix for T5345 dropped a necessary adjusment in the case of
get_first_key=False.

* T5195: move run, cmd, call, rc_cmd helper to vyos.utils.process
* T5195: use read_file and write_file implementation from vyos.utils.file
Changed code automatically using:
find . -type f -not -path '*/\.*' -exec sed -i 's/^from vyos.util import read_file$/from vyos.utils.file import read_file/g' {} +
find . -type f -not -path '*/\.*' -exec sed -i 's/^from vyos.util import write_file$/from vyos.utils.file import write_file/g' {} +

config: T5330: add boolean check for additions by default in config dict
|
|
|
|
This check can raise a false positive exception in the case of a
tag-node value name equal to the tag-node name; it is unneeded in any
case as the functions are called with well-defined paths, respectively,
with a correct verification.

VPP: T1797: Optimizations for VPP memory allocation during startup

T5314: Fix default QOS classes not getting qdisc
|
|
|
|
|
|
- modified `sysctl_read()` to return the whole value
- modified `sysctl_write()` logic to return `True` only in case a value was
changed successfully
- added `sysctl_apply()` to apply a dictionary of values at once

Prevent duplicatte prio fot tc command
|
|
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
|
|
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: Add initial vpp configuration
|
|
- 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
|
|
|
|
- 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.
|
|
Replaced CLI commands with API calls.
CLI commands still can be used via:
```
vpp_control = VPPControl()
vpp_control.cli_cmd('command_here')
```
|
|
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
|
|
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.
|
|
|
|
|
|
|
|
At boot, the util function check_port_availability can return False with
EADDRNOTAVAIL if the interface is not yet up; check explicitly for
address in use.
