50a021df33 tests: use virfirewallmock instead of hasNetfilterTools
Instead of checking for specific error that the binaries are not
available mock the virFindFileInPath function. This way we don't have
to skip these tests on host where the binaries are missing.

c8238579fb lib: Drop internal virXXXPtr typedefs
Historically, we declared pointer type to our types:

  typedef struct _virXXX virXXX;
  typedef virXXX *virXXXPtr;

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:

0dffca8f95 virCommandSetDryRun: Rework resetting of the dry run data
While virCommandSetDryRun is used in tests only, there were some cases
when error paths would not call the function with NULL arguments to
reset the dry run infrastructure.

Introduce virCommandDryRunToken type which must be allocated via
virCommandDryRunTokenNew and passed to virCommandSetDryRun.

This way we can use automatic variable cleaning to trigger the cleanup
of virCommandSetDryRun parameters and also the use of the token variable
ensures that all callers of virCommandSetDryRun clean up after
themselves and also that the token isn't left unused in the code.

b19863640d util: call iptables directly rather than via firewalld
When libvirt added support for firewalld, we were unable to use
firewalld's higher level rules, because they weren't detailed enough
and could not be applied to the iptables FORWARD or OUTPUT chains
(only to the INPUT chain). Instead we changed our code so that rather
than running the iptables/ip6tables/ebtables binaries ourselves, we
would send these commands to firewalld as "passthrough commands", and
firewalld would run the appropriate program on our behalf.

This was done under the assumption that firewalld was somehow tracking
all these rules, and that this tracking was benefitting proper
operation of firewalld and the system in general.

Several years later this came up in a discussion on IRC, and we
learned from the firewalld developers that, in fact, adding iptables
and ebtables rules with firewalld's passthrough commands actually has
*no* advantage; firewalld doesn't keep track of these rules in any
way, and doesn't use them to tailor the construction of its own rules.

Meanwhile, users have been complaining for some time that whenever
firewalld is restarted on a system with libvirt virtual networks
and/or nwfilter rules active, the system logs would be flooded with
warning messages whining that [lots of different rules] could not be
deleted because they didn't exist. For example:

firewalld[3536040]: WARNING: COMMAND_FAILED:
  '/usr/sbin/iptables -w10 -w --table filter --delete LIBVIRT_OUT
  --out-interface virbr4 --protocol udp --destination-port 68
  --jump ACCEPT' failed: iptables: Bad rule
  (does a matching rule exist in that chain?).

(See https://bugzilla.redhat.com/1790837 for many more examples and a
discussion)

Note that these messages are created by iptables, but are logged by
firewalld - when an iptables/ebtables command fails, firewalld grabs
whatever is in stderr of the program, and spits it out to the system
log as a warning. We've requested that firewalld not do this (and
instead leave it up to the calling application to do the appropriate
logging), but this request has been respectfully denied.

But combining the two problems above ( 1) firewalld doesn't do
anything useful when you use it as a proxy to add/remove iptables
rules, 2) firewalld often insists on logging lots of
annoying/misleading/useless "error" messages when you use it as a
proxy to remove iptables rules that don't already exist), leads to a
solution - simply stop using firewalld to add and remove iptables
rules. Instead, exec iptables/ip6tables/ebtables directly in the same
way we do when firewalld isn't active.

We still need to keep track of whether or not firewalld is active, as
there are some things that must be done, e.g. we need to add some
actual firewalld rules in the firewalld "libvirt" zone, and we need to
take notice when firewalld restarts, so that we can reload all our
rules.

This patch doesn't remove the infrastructure that allows having
different firewall backends that perform their functions in different
ways, as that will very possibly come in handy in the future when we
want to have an nftables direct backend, and possibly a "pure"
firewalld backend (now that firewalld supports more complex rules, and
can add those rules to the FORWARD and OUTPUT chains). Instead, it
just changes the action when the selected backend is "firewalld" so
that it adds rules directly rather than through firewalld, while
leaving as much of the existing code intact as possible.

In order for tests to still pass, virfirewalltest also had to be
modified to behave in a different way (i.e. by capturing the generated
commandline as it does for the DIRECT backend, rather than capturing
dbus messages using a mocked dbus API).

e9693502fb tests: fix iptables test case commandline options in virfirewalltest.c
This test was created with all the commandlines erroneously having
"--source-host", which is not a valid iptables option. The correct
name for the option is "--source". However, since the test is just
checking that the generated commandline matches what we told it to
generate (and never actually runs iptables, as that would be a "Really
Bad Idea"(tm)), the test has always succeeded. I only found it because
I made a change to the code that caused the test to incorrectly try to
run iptables during the test, and the error message I received was
"odd" (it complained about the bad option, rather than complaining
that I had insufficient privilege to run the command).

0a867cd895 util/tests: enable locking on iptables/ebtables commandlines by default
iptables and ip6tables have had a "-w" commandline option to grab a
systemwide lock that prevents two iptables invocations from modifying
the iptables chains since 2013 (upstream commit 93587a04 in
iptables-1.4.20).  Similarly, ebtables has had a "--concurrent"
commandline option for the same purpose since 2011 (in the upstream
ebtables commit f9b4bcb93, which was present in ebtables-2.0.10.4).

Libvirt added code to conditionally use the commandline option for
iptables/ip6tables in upstream commit ba95426d6f (libvirt-1.2.0,
November 2013), and for ebtables in upstream commit dc33e6e4a5
(libvirt-1.2.11, November 2014) (the latter actually *re*-added the
locking for iptables/ip6tables, as it had accidentally been removed
during a refactor of firewall code in the interim).

I say "conditionally" because a check was made during firewall module
initialization that tried executing a test command with the
-w/--concurrent option, and only continued using it for actual
commands if that test command completed successfully. At the time the
code was added this was a reasonable thing to do, as it had been less
than a year since introduction of -w to iptables, so many distros
supported by libvirt were still using iptables (and possibly even
ebtables) versions too old to have the new commandline options.

It is now 2020, and as far as I can discern from repology.org (and
manually examining a RHEL7.9 system), every version of every distro
that is supported by libvirt now uses new enough versions of both
iptables and ebtables that they all have support for -w/--concurrent.
That means we can finally remove the conditional code and simply
always use them.

e66451f685 util/tests: enable locking on iptables/ebtables commandlines in unit tests
All the unit tests that use iptables/ip6tables/ebtables have been
written to omit the locking/exclusive use primitive on the generated
commandlines. Even though none of the tests actually execute those
commands (and so it doesn't matter for purposes of the test whether or
not the commands support these options), it still made sense when some
systems had these locking options and some didn't.

We are now at a point where every supported Linux distro has supported
the locking options on these commands for quite a long time, and are
going to make their use non-optional. As a first step, this patch uses
the virFirewallSetLockOverride() function, which is called at the
beginning of all firewall-related tests, to set all the bools
controlling whether or not the locking options are used to true. This
means that all the test cases must be updated to include the proper
locking option in their commandlines.

The change to make actual execs of the commands unconditionally use
the locking option will be in an upcoming patch - this one affects
only the unit tests.

600462834f Remove all Author(s): lines from source file headers
In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.

In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.

With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to  find the
author of a particular bit of code.

This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.

The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

3a0ca7de51 Introduce an object for managing firewall rulesets
The network and nwfilter drivers both have a need to update
firewall rules. The currently share no code for interacting
with iptables / firewalld. The nwfilter driver is fairly
tied to the concept of creating shell scripts to execute
which makes it very hard to port to talk to firewalld via
DBus APIs.

This patch introduces a virFirewallPtr object which is able
to represent a complete sequence of rule changes, with the
ability to have multiple transactional checkpoints with
rollbacks. By formally separating the definition of the rules
to be applied from the mechanism used to apply them, it is
also possible to write a firewall engine that uses firewalld
DBus APIs natively instead of via the slow firewalld-cmd.
