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

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.
|
|
|
|
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.

vyos.util: T5300: check_port_availability should return False only on EADDRINUSE
|
|
|
|
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.

T5071: QoS add class match DSCP value
|
|
QoS DSCP match is skipped
Add it
set qos policy shaper test class 23 match 10 ip dscp 'network'
tc filter replace dev eth0 parent 1: protocol all u32 match ip dsfield 224 0xff flowid 1:17

T5296: Fix QoS class bandwidth calculation for auto and percent
|
|
T5256: T5195: Fix QoS match protocol and add vyos.utils.network
|
|
tc filter exepcts protocol number for match instead of protocol name
|
|
|
|
There are wrong bandwidth calculations for the class
We shouldn't rely on interface speed but we should get this value
from 'shaper <tag> bandwidth xxx' if configured 'auto' or
bandwidth with '%'
Otherwise we can get unexpected rate for the class
% sudo cat /sys/class/net/eth0/speed
% -1
generated rate:
classid 1:17 htb rate -1000000
Fix this

T5295: Fix QoS shaper rate limit
|
|
|
|
Do not handle rate via 'tc filter' directly but rather set the
'tc filter' to direct traffic to the correct tc class flow.
As it in 1.3.
It fixes random unexpected shapes, when you set for example 300mbit
but get 3-11mbit
Current implementation seems not correct as it uses rate limits
two times (in class and in filter):
tc class replace dev eth0 parent 1:1 classid 1:17 htb rate 250000000 \
burst 15k quantum 1514
tc filter replace dev eth0 parent 1: protocol all u32 match \
ip dst 192.168.122.11 action police rate 250000000 burst 15k flowid 1:17
The correct way after fix:
tc class replace dev eth0 parent 1:1 classid 1:17 htb rate 250000000 \
burst 15k quantum 1514
tc filter replace dev eth0 parent 1: protocol all u32 match \
ip dst 192.168.122.11 flowid 1:17

T5290: Failing commits for SR-IOV interfaces using ixgbevf driver due…
|
|
change speed/duplex settings
This is the same problem as reported in T4297. By definition it is not possible to change speed and duplex settings at SR-IOV virtual functions driven by ixgbevf driver. I think the solution is the same as well, that is to add 'ixgbevf' into _drivers_without_speed_duplex_flow in /usr/lib/python3/dist-packages/vyos/ethtool.py. It fixed the problem for me with Intel x520 NICs.

T5282: remove systemd management directive for frr.service

- For option 'web', ddclient defaults to 'dyndns' which doesn't support
ssl. This results ddclient process lockup till connection to
checkip.dyndns.org:443 times out.
- For option 'use', ddclient defaults 'ip'. This results in confusing
message "WARNING: '' is not a valid IPv4 or IPv6 address" in log.
