Standardized function that removes format spaces (or tab) and carriage

Becomes:
*N IA 2001:db8:2::/64 :: r2-eth0 00:03:39
If you remove 'IA' you won't have space formatting problem anymore.
Having a generic start/stop methods for TopoGear allows TopoGen to call
start/stop for all equipments. This allows us to reduce the teardown
code by removing the necessity of having to always remember to call
each equipment clean up function.
Auto configure daemon logging files to the appropriated place. This
removes the responsibility from the test developer to set this in the
daemon configuration.
TopoRouters now create a logger (which logs to /tmp/{router_name}.log)
on start to record all commands and events that it goes through. All log
messages contain timestamps that may be used in the future to:
(1) correlate commands call with events
(2) benchmark/time command speed
Allow topotest subsystems to create their own loggers. This will help
increase log organization and allow different settings to fit the
subsystems needs.
The default logger (root) is already being used by Mininet, so to allow
customizing logging output and configuring log files Topolog was
created. Topolog is no more than a thin layer abstraction to call
logging functions without using the 'root' logger.
Use a configuration file for casual settings like:
* Verbosity level (helps when debugging mininet issues)
* Custom daemon directory (in order to support running different daemon
binaries without touching tests)
* Daemon type switch: allow running quagga without touching any test
files
Also fix the add_router() documentation to include all options.
Create a specialized assert and json_cmp() result to improve the
comparison output. With this we also got a way to display all comparison
failures instead of just the first one.
This allows old tests to be run with '--topology-only' without

without trying anything else.
Allow vtysh_cmd() to convert JSON output to Python data structures.
This feature will be used to get vtysh JSON outputs for tests

Usage example:
```py
router = get_topogen().gears['r1']
json_output = router.vtysh_cmd('show ip ospf json', isjson=True)
json_cmp(json_output, {'important_key': 'important_value'})
```
Implemented a JSON compare function that tells you when a specific
subset of items exist or not inside a JSON dataset.
More details can be found in the function docstring or in the test file
lib/test_json.py.
After some feedback from mwinter@, the names of equipments are now
shorter to make it easier to type them and to keep consistency with
mininet documentation. While here, update the template and make it use
optional name parameters for clarity.
Adding the __init__.py file makes python and its linter recognize that
the test makes part of the package, this makes us save a few lines of
code to make the linter and auto complete engines happy.
This commit changes how topology links are made in order to support
discovering who and what link is the node interface connected to. After
that, the implementation of the link state change functions were trivial
as calling a command in the node shell.
The method run() was moved from TopoRouter to TopoGear so all equipment
types can benefit from this code.
Topogen (Topology Generator) is a helper that wraps around Topotest to
simplify some of the boilerplate code. This abstraction will help the
development of new tests and new APIs without breaking the existing
ones. It also makes the relation of objects clearer, since we no longer
touch the Mininet API directly, which in turn also makes us less
vulnerable to external API changes.
Implemented two functions to help setting sysctl values:
* set_sysctl: set a sysctl and return an auditable return value

The northbound infrastructure for operational data was subpar compared
to the infrastructure for configuration data. This commit addresses most
of the existing problems, making it possible to write operational-data
callbacks for more complex YANG models.
Summary of the changes:
* Add support for nested YANG lists.
* Add support for leaf-lists.
* Add support for leafs of type "empty".
* Introduce the "show yang operational-data XPATH" command, and write an
unit test for it. The main purpose of this command is to make it
easier to test the operational-data northbound callbacks.
* Introduce the nb_oper_data_iterate() function, that can be used
to iterate over operational data. Make the CLI and sysrepo use this
function.
* Since ConfD has a very peculiar API, it can't reuse the
nb_oper_data_iterate() like the other northbound clients. In this
case, adapt the existing ConfD callbacks to support the new features
(and make some performance improvements in the process).

The motivation for this patch is to address a concerning behavior of
tx-addpath-bestpath-per-AS. Prior to this patch, all paths' TX ID was
pre-determined as the path was received from a peer. However, this meant
that any time the path selected as best from an AS changed, bgpd had no
choice but to withdraw the previous best path, and advertise the new
best-path under a new TX ID. This could cause significant network
disruption, especially for the subset of prefixes coming from only one
AS that were also communicated over a bestpath-per-AS session.
The patch's general approach is best illustrated by
txaddpath_update_ids. After a bestpath run (required for best-per-AS to
know what will and will not be sent as addpaths) ID numbers will be
stripped from paths that no longer need to be sent, and held in a pool.
Then, paths that will be sent as addpaths and do not already have ID
numbers will allocate new ID numbers, pulling first from that pool.
Finally, anything left in the pool will be returned to the allocator.
In order for this to work, ID numbers had to be split by strategy. The
tx-addpath-All strategy would keep every ID number "in use" constantly,
preventing IDs from being transferred to different paths. Rather than
create two variables for ID, this patch create a more generic array that
will easily enable more addpath strategies to be implemented. The
previously described ID manipulations will happen per addpath strategy,
and will only be run for strategies that are enabled on at least one
peer.
Finally, the ID numbers are allocated from an allocator that tracks per
AFI/SAFI/Addpath Strategy which IDs are in use. Though it would be very
improbable, there was the possibility with the free-running counter
approach for rollover to cause two paths on the same prefix to get
assigned the same TX ID. As remote as the possibility is, we prefer to
not leave it to chance.
This ID re-use method is not perfect. In some cases you could still get
withdraw-then-add behaviors where not strictly necessary. In the case of
bestpath-per-AS this requires one AS to advertise a prefix for the first
time, then a second AS withdraws that prefix, all within the space of an
already pending MRAI timer. In those situations a withdraw-then-add is
more forgivable, and fixing it would probably require a much more
significant effort, as IDs would need to be moved to ADVs instead of
paths.

This commit introduces lib/id_alloc, which has facilities for both an ID number
allocator, and less efficient ID holding pools. The pools are meant to be a
temporary holding area for ID numbers meant to be re-used, and are implemented
as a linked-list stack.
The allocator itself is much more efficient with memory. Based on sizeof
values on my 64 bit desktop, the allocator requires around 155 KiB per
million IDs tracked.
IDs are ultimately tracked in a bit-map split into many "pages." The
allocator tracks a list of pages that have free bits, and which sections
of each page have free IDs, so there isn't any scanning required to find
a free ID. (The library utility ffs, or "Find First Set," is generally a
single CPU instruction.) At the moment, totally empty pages will not be
freed, so the memory utilization of this allocator will remain at the
high water mark.
The initial intended use case is for BGP's TX Addpath IDs to be pulled
from an allocator that tracks which IDs are in use, rather than a free
running counter. The allocator reserves ID #0 as a sentinel value for
an invalid ID numbers, and BGP will want ID #1 reserved as well. To
support this, the allocator allows for IDs to be explicitly reserved,
though be aware this is only practical to use with low numbered IDs
because the allocator must allocate pages in order.

This commit finalizes the previous commits which introduced a generic
approach for making all BGP peer and address-family attributes
overrideable by keeping track of the configuration origin in separate
internal structures.
First of all, the test suite was greatly extended to also check the
internal data structures of peer/AF attributes, so that inheritance for
internal values like 'peer->weight' is also being checked in all cases.
This revealed some smaller issues in the implementation, which were also
fixed in this commit. The test suite now fully passes and covers all the
usual situations that should normally occur.

This commit introduces BGP peer-group overrides for the last set of
peer-level attrs which did not offer that feature yet. The following
attributes have been implemented: description, local-as, password and
update-source.
Each attribute, with the exception of description because it does not
offer any inheritance between peer-groups and peers, is now also setting
a peer-flag instead of just modifying the internal data structures. This
made it possible to also re-use the same implementation for attribute
overrides as already done for peer flags, AF flags and AF attrs.
The `no neighbor <neigh> description` command has been slightly changed
to support negation for no parameters, one parameter or * parameters
(LINE...). This was needed for the test suite to pass and is a small
change without any bigger impact on the CLI.

This commit implements BGP peer-group overrides for the timer flags,
which control the value of the hold, keepalive, advertisement-interval
and connect connect timers. It was kept separated on purpose as the
whole timer implementation is quite complex and merging this commit
together with with the other flag implementations did not seem right.
Basically three new peer flags were introduced, namely
*PEER_FLAG_ROUTEADV*, *PEER_FLAG_TIMER* and *PEER_FLAG_TIMER_CONNECT*.
The overrides work exactly the same way as they did before, but
introducing these flags made a few conditionals simpler as they no
longer had to compare internal data structures against eachother.
Last but not least, the test suite has been adjusted accordingly to test
the newly implemented flag overrides.

The current implementation of the overrides for peer address-family

This commit extends the *peer_group2peer_config_copy_af* function to
respect overridden flags properly. Additionally, the arguments of the
macros *PEER_ATTR_INHERIT* and *PEER_STR_ATTR_INHERIT* have been
reordered to be more consistent and easy to read.
This commit also adds further test cases to the BGP peer attributes test
suite, so that this kind of error is being caught in future commits. The

The current implementation of peer flags (e.g. shutdown, passive, ...)
only has partial support for overriding flags of a peer-group when the
peer is a member. Often settings might get lost if the user toys around
with the peer-group configuration, which can lead to disaster.
This commit introduces the same override implementation which was
previously integrated to support proper peer flag/attribute override on
the address-family level. The code is very similar and the global
attributes now use their separate state-arrays *flags_invert* and
*flags_override*.
The test suite for BGP peer attributes was extended to also check peer
global attributes, so that the newly introduced changes are covered. An
additional feature was added which allows to test an attribute with an
*interface-peer*, which can be configured by running `neighbor IF-TEST
interface`. This was introduced so that the dynamic runtime inversion of
the `extended-nexthop` flag, which is only enabled by default for
interface peers, can also be tested.
Last but not least, two small changes have been made to the current bgpd
implementation:
- The command `strict-capability-match` can now also be set on a
peer-group, it seems like this command slipped through while
implementing peer-groups in the very past.
- The macro `COND_FLAG` was introduced inside lib/zebra.h, which now
allows to either set or unset a flag based on a condition. The syntax
for using this macro is: `COND_FLAG(flag_variable, flag, condition)`

This commit introduces unit tests for BGP peer attributes and checks all
three involved components, which are:
- CLI Configuration Input: The appropriate commands to configure the
attribute on either a peer or peer-group are being executed the same way
an end user would do it.
- CLI Configuration Output: The output of 'show running-config' is being
checked for presence/absence of expected configuration strings.
- Internal Data Structures: The internal data structures for maintaining
flag/filter states (value + override + invert) are being checked after
each operation to ensure the override has been implemented properly.
All attributes to be tested must be defined within the 'peer_attrs'
structure, which contains all peer attributes as of today and checks
them with both IPv4 Unicast and IPv6 Unicast. More address families are
supposed to be introduced at a later point in time.
Each attribute is being checked in its own 'clean' BGP environment, so
everything gets reset after each attribute to avoid any weird edge
cases. The 'correct' BGP startup and shutdown routine was taken from
'bgp_main.c' to ensure that we are not leaking any memory or acting
different than the real 'bgpd' would do.

Fuzzing with tools like afl requires the ability to quickly/easily
call a function to test it's input. In the case of bgp we
need the ability to test bgp's packet handler quickly. This
added program bgpd/test_packet takes a file name as input
that it treats as normal bgp communication between itself
and a peer.

Convert the list_delete(struct list *) function to use
struct list **. This is to allow the list pointer to be nulled.
I keep running into uses of this list_delete function where we
forget to set the returned pointer to NULL and attempt to use
it and then experience a crash, usually after the developer
has long since left the building.
Let's make the api explicit in it setting the list pointer
to null.
Cynical Prediction: This code will expose a attempt
to use the NULL'ed list pointer in some obscure bit
of code.

This adds "@tcp" as new choice on the -z option present in zebra and the
protocol daemons. The --enable-tcp-zebra option on configure is no
longer needed, both UNIX and TCP socket support is always available.
Note that @tcp should not be used by default (e.g. in an init script),
and --enable-tcp-zebra should never have been in any distro package
builds, because

BUILT_SOURCES doesn't do what the name suggests. What it actually means
is "these files should be built first when doing a 'make' without
explicit target" (or "make all").
It's pretty much almost always wrong to use BUILT_SOURCES, the only
correct use is when a file is needed by an unspecified / large set of
files.
Also remove version.h and route_types.h from dist tarball while we're at
it. configure will create them anyway.

pytest.mark.skipif apparently iterates through a class's methods,
applying itself onto the various methods. Now, since we're deriving
from a parent class, the method is actually the same object inherited
from the parent, so the decorator will apply itself on the parent's
testrunning method (test_refout). The result is that any TestRefout
tests after "test_commands.py" will be skipped...
This only became apparent after adding ospf6d/test_lsdb.py; before,
test_commands.py was the last test in the list so it didn't matter...

A partially-entered IPv6 address would never return a "partly_match",

This specifically breaks autocompleting BGP IPv6 neighbor addresses.

Pass pointer to pointer instead of assigning by return value. See
previous commit message.
To ensure that the behavior stays functionally correct, any assignments
with the result of a thread_add* function have been transformed to set
the pointer to null before passing it. These can be removed wherever the
pointer is known to already be null.

The way thread.c is written, a caller who wishes to be able to cancel a
thread or avoid scheduling it twice must keep a reference to the thread.
Typically this is done with a long lived pointer whose value is checked
for null in order to know if the thread is currently scheduled. The
check-and-schedule idiom is so common that several wrapper macros in
thread.h existed solely to provide it.
This patch removes those macros and adds a new parameter to all
thread_add_* functions which is a pointer to the struct thread * to
store the result of a scheduling call. If the value passed is non-null,
the thread will only be scheduled if the value is null. This helps with
consistency.
A Coccinelle spatch has been used to transform code of the form:
if (t == NULL)
t = thread_add_* (...)
to the form
thread_add_* (..., &t)
The THREAD_ON macros have also been transformed to the underlying
thread.c calls.

Label Manager allows to share MPLS label space among different
daemons. Each daemon can request a chunk of consecutive labels and
release it if it doesn't need them anymore. Label Manager stores the
daemon protocol and instance to identify the owner client. It uses them
to perform garbage collection, releasing all label chunks from a client
when it gets disconnected or reconnected.
Additionally, every client can request that the chunk is never garbage
collected. In that case client has the responsibility to release
non-used labels.
Zebra can host the label manager itself (if no -l param is provided) or
connect to an external one using zserv/zclient (providing its address
with -l param).
Client code is in lib/zclient.c, but currently only LDP is using it.
TODO: Allow for custom ranges requests, i.e., specify the start label
besides the chunk.
TODO: Release labels from LDP.
