Migrate CLI configuration retrival to common get_config_dict(). In addition
add new functionality to VyOS that is PIM related and already available in FRR.
|
|
|
|
Currently VyOS has `protocol igmp` option to enable IGMP querier and reports through FRR's pimd.
I would like to add support for IPv6 as well since FRR's IPv6 multicast functionality has significantly improved.
Enabling both MLD and IGMP on a VyOS router will allow us to turn on multicast snooping on layer-3 switches in dual-stack networks.
Example commands:
```
// Enable on interface eth0
set protocols pim6 interface eth0
// Explicitly join multicast group ff18::1234 on interface eth1
set protocols pim6 interface eth1 mld join ff18::1234
// Explicitly join source-specific multicast group ff38::5678 with source address 2001:db8::1 on interface eth1
set protocols pim6 interface eth1 mld join ff38::5678 source 2001:db8::1
```

* 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' {} +

This PR adds basic Babel routing protocol support using the implementation in
FRR.

frr.py debugging is set True if the file '/tmp/vyos.frr.debug' exists;
this check needs to be called within an init function, as frr.py will
have already been loaded by vyos-configd before the /tmp/*.debug files
are created by vyos-router, or by call to 'touch'.

As a result to some frr-reload bugs workarounded in commit 3800ea91 or fe0038c2
this commit adds the workaround in general.

This will enable more debugging on the frr reload library, changes:
* Adds a /tmp/vyos.frr.debug hook to enable system wide vyos.frr debugging
* Log the initial imported configs
* Log the FRR config submitted to frr-reload
* redirecting frr-reload output to the debug log.

using multiline regexes are quite hard to "read" and are really
easy to mess up, this commit adds a new more pythonic
implementation of the library that do not need any multiline regexes.

because of a bug in frr.py the default before_re will not be working.
it is by default without a group, but will be used in a match that needs a group.
The whole string could be matched in the group, so the fix is easy to implement.

This commit adds the python module vyos.frr that support reading and modifying the frr cofiguration.
Functions
get_configuration() :
Collects the configuration from FRR and returns it as a string
reload_configuration() :
uses frr-reload.py to activate a new configuration.
The configuration applied will overwrite the current configuration.
mark_configuration() :
Does syntax check/validation and add "end" tags to the configuration
The marked configuration will be returned as a string
A syntax fault will render an Exception
execute() :
Execute a command inside vtysh
configure() :
Executes a command in vtysh config mode
replace_section() / _replace_section() :
Adds the ability to replace a section of frr code
remove_section() :
Removes the specified configuration block from the config
For now this supports replacing complete config sub-blocks of configuration and selecting the daemon
to replace inside. This should work for most daemons, but static routing will still be an issue because
this is not a separate sub-config mode
