pbrd: Optional JSON output for all `show pbr` directives
|
|
Just add a basic test for pbr. This code
does not actually test installation in the kernel at this
point in time.
What we do do is make sure pbr is in a sane state after
some very basic configuration.

Just a simple setup for pbr to prove it starts. Once the json
code for pbr gets in we can add more.

ospfd: Solve crash after removing and adding conf.
|
|
topotest: refactory BGP VRF leak basic test
|
|
Issue number #6291 describes how OSPFd crashes after being deleted and then
added again with configuration when segment routing is used.
The problem occurs in ospf_ri.c because the OspfRI structures retains
the reference to the old area pointer which is mofified when ospfd is
reactivated by configuration. When segment routing is activated, the LSA Router
Information is sent with reference to the old area pointer, instead the new one,
which causes the crash. The same problem is also present in ospf_ext.c with
OspfEXT structure and Extended Link/Prefix structure.
This commit introduces Extended Link/Prefix and Router Information LSAs flusing
when OSPFd is stopped when configuration is removed and adds the correct
initialization to the area pointer in OspfRI and Extended Link/Prefix structure
when OSPFd is re-enabled with the configuration. Area pointer has been removed
from the OspfEXT structure as it is never used with this commit.

The involved piece of code is supposed to find a 'closest' match for two
JSON structures using another JSON diff. However, it can happen that
during that new diff the JSON structures are altered (elements from a
list are deleted when 'found'). This is in general ok when the deleted
element is part of the JSON structure which 'matches', but when it later
turns out that some other element of the structure doesn't fit, then the
whole structure should be recovered. This is now realized by using a
deepcopy for the besaid new JSON diff such that the original is only
altered (e.g. deleted) when the diff is clean.

Each router has both an IPv4 and an IPv6 loopback address, each of
which has a corresponding Prefix-SID configured.
Basic SR functionality is tested. First, the topotest ensures that
all expected Prefix-SIDs and Adj-SIDs are flooded and installed
correctly in all routers of the network. Later, network failures
are simulated and configuration changes are performed in several
different routers. The topotest then checks if IS-IS has converged
as expected in the network according to the network failures and
configuration changes that happened.
The topotest comprises 11 different steps, each with four individual
tests (for a total of 44 tests). A summary of what each step does
is provided below:
---
STEP 1:
-Initial network convergence
---
Step 2:
Action(s):
-Disable IS-IS on the eth-rt5 interface on rt4
Expected changes:
-rt4 should uninstall the Adj-SIDs pointing to rt5
-rt5 should uninstall the Adj-SIDs pointing to rt4
-rt2 should reinstall rt5's Prefix-SIDs (2 nexthops deleted)
-rt3 should reinstall rt4's Prefix-SIDs (2 nexthops deleted)
-rt4 should reinstall rt3's Prefix-SIDs (1 nexthop deleted)
-rt4 should reinstall rt5's Prefix-SIDs (1 nexthop changed)
-rt5 should reinstall rt2's Prefix-SIDs (1 nexthop deleted)
-rt5 should reinstall rt4's Prefix-SIDs (1 nexthop changed)
---
Step 3:
Action(s):
-Shut down the eth-rt4 interface on rt6
-Shut down the eth-rt5 interface on rt6
Expected changes:
-All routers should uninstall rt6's Prefix-SIDs
-rt4 and rt5 should uninstall the Adj-SIDs pointing to rt6
-rt4 should reconverge rt5's Prefix-SIDs through rt2 using ECMP
-rt5 should reconverge rt4's Prefix-SIDs through rt3 using ECMP
-rt6 should uninstall all its IS-IS routes, Prefix-SIDs and Adj-SIDs
---
Step 4:
Action(s):
-Bring up the eth-rt4 interface on rt6
-Bring up the eth-rt5 interface on rt6
-Change rt6's SRGB
Expected changes:
-All routers should install rt6's Prefix-SIDs
-rt4 and rt5 should install Adj-SIDs for rt6
-rt4 should reconverge rt5's Prefix-SIDs through rt6 using the new SRGB
-rt5 should reconverge rt4's Prefix-SIDs through rt6 using the new SRGB
-rt6 should reinstall all IS-IS routes and Prefix-SIDs from the network,
and Adj-SIDs for rt4 and rt5
---
Step 5:
Action(s):
-Disable SR on rt6
Expected changes:
-All routers should uninstall rt6's Prefix-SIDs
-rt4 should uninstall rt5's Prefix-SIDs since the nexthop router hasn't
SR enabled anymore
-rt5 should uninstall rt4's Prefix-SIDs since the nexthop router hasn't
SR enabled anymore
-rt6 should uninstall all Prefix-SIDs from the network, and the Adj-SIDs
for rt4 and rt5
---
Step 6:
Action(s):
-Enable SR on rt6
Expected changes:
-All routers should install rt6's Prefix-SIDs
-rt4 should install rt5's Prefix-SIDs through rt6
-rt5 should install rt4's Prefix-SIDs through rt6
-rt6 should install all Prefix-SIDs from the network, and Adj-SIDs for
rt4 and rt5
---
Step 7:
Action(s):
-Delete rt1's Prefix-SIDs
Expected changes:
-All routers should uninstall rt1's Prefix-SIDs
---
Step 8:
Action(s):
-Re-add rt1's Prefix-SIDs
Expected changes:
-All routers should install rt1's Prefix-SIDs
---
Step 9:
Action(s):
-Change rt1's Prefix-SIDs to use the no-php option
-Change rt6's Prefix-SIDs to stop using the explicit-null option
Expected changes:
-rt2 and rt3 should reinstall rt1's Prefix-SIDs accordingly
-rt4 and rt5 should reinstall rt6's Prefix-SIDs accordingly
---
Step 10:
Action(s):
-Remove the IPv4 address from rt4's eth-rt2-1 interface
Expected changes:
-rt2 should uninstall the IPv4 Adj-SIDs attached to the eth-rt4-1
interface
-rt2 should reinstall all IPv4 Prefix-SIDs whose nexthop router is rt4
(ECMP shouldn't be used anymore)
-rt4 should reinstall all IPv4 Prefix-SIDs whose nexthop router is rt2
(ECMP shouldn't be used anymore)
---
Step 11:
Action(s):
-Restore the original network setup
Expected changes:
-All routes, Prefix-SIDs and Adj-SIDs should be the same as they were
after the initial network convergence (step 1)

Diff'ing JSON objects is a crucial operation in the topotests for
comparing e.g. vtysh output (formatted as JSON) with a file which
covers the expectation of the tests. The current diff functionality
is 'self-written' and intended to test a JSON object d2 on being a
subset of another JSON object d1. For mismatches a diff is generated
based on a normalized textual representation of the JSON objects.
This approach has several disadvantages:
* the human provided JSON text might not be normalized, hence
a diff with line numbers might be worthless since it provides
close to zero orientation what the problem is
* the diff contains changes like commatas which are meaningless
* the diff might contain a lot of changes about meaningless
content which is present in d1 but not in d2
* there is no proper functionality to test for 'equality' of
d1 and d2
* it is not possible to test for order, e.g. JSON arrays are
just tested with respect to being a subset of another array
* it is not possible to check if a key exists without also
checking the value of that particular key
This commit attempts to solve these issues. An error report is
generated which includes the "JSON Path" to the problematic JSON
elements and also hints on what the actual problem is (e.g. missing
key, mismatch in dict values etc.).
A special parameter 'exact' was introduced such that equality can be
tested. Also there was a convention that absence of keys can be
tested using the key in question with value 'None'. This convention
is still honored such that full backwards compatiiblity is in
place.
Further order can be tested using the new tag '__ordered__' in
lists (as first element). Example:
d1 = [1, 2, 3]
d2 = ['__ordered__', 1, 3, 2]
Tesing d1 and d2 this way will now result in an error.
Key existence can now be tested using an asterisk '*'. Example:
d1 = [1, 2, 3]
d2 = [1, '*', 3]
d1 = {'a': 1, 'b': 2}
d2 = {'a': '*'}
Both cases will result now in a clean diff for d1 and d2.

bgpd: Show PfxSnt for `show bgp <afi> <safi>` command

Having a fixed set of parameters for each northbound callback isn't a
good idea since it makes it difficult to add new parameters whenever
that becomes necessary, as several hundreds or thousands of existing
callbacks need to be updated accordingly.
To remediate this issue, this commit changes the signature of all
northbound callbacks to have a single parameter: a pointer to a
'nb_cb_x_args' structure (where x is different for each type
of callback). These structures encapsulate all real parameters
(both input and output) the callbacks need to have access to. And
adding a new parameter to a given callback is as simple as adding
a new field to the corresponding 'nb_cb_x_args' structure, without
needing to update any instance of that callback in any daemon.
This commit includes a .cocci semantic patch that can be used to
update old code to the new format automatically.

- sprintf's into local scope buffers of known size are replaced with the
equivalent snprintf call
- snprintf's into local scope buffers of known size that use the buffer
size expression now use sizeof(buffer)
- sprintf(buf + strlen(buf), ...) replaced with snprintf() into temp
