10:53 p.m.
This patch adds new test cases to the existing nwfilter test program and
adds a test script that must be run while a VM is running. This test
script verifies that input network filter XML creates expected
user-defined tables and rules on ebtables, iptables & ip6tables layer
and verifies their content against expected content. The idea is that
these tools always return exactly the same output when displaying the
content of a user-defined table so that the diff tool can be used for
simple text comparison. All supported protocols have at least one test
case.
This test program is not run automatically since it requires a running
VM.
For all tests to pass the previously posted ICMP fix patch must be applied.

+Run this program while a KVM VM is running (preferably as only VM on the
+system) and one of its interfaces uses a filter called 'testcase'. The name
+of the interface of the VM is anticipated to be 'vnet0' unless set by the
+'--ifname' option. The following interface description fulfills this
+requirement:
+
+ <interface type='bridge'>
+ <source bridge='virbr0'/>
+ <target dev='vnet0'/>
+ <filterref filter='testcase'/>
+ </interface>
+
+The individual tests are validated using string comparison where the output
+of ebtables, iptables and ip6tables is compared against expected output. As
+long as the output of those tools is the same, the tests should all pass.
+The tests were developed on Fedore Core 12.
+
+Known problems: None of the running VMs' names may have spaces.

I'll change this to be a bash script. No point in making the test program

Hm, two hardcoded files like '/tmp/nwfiltervmtest1' and

Good to know... will change even though the tests would not succeed on
Solaris.
I'll do a check using 'uname' to fail early on anything else than
'Linux'.

Would that be safer as:
main "$@"
My review stops here - shell is my area of expertise, but my Linux
network filtering knowledge is sparse.
Ok. Thanks for the review. Will adapt and re-post.

I'll change this to be a bash script. No point in making the test program
portable across shells.

Hm, two hardcoded files like '/tmp/nwfiltervmtest1' and
'/tmp/nwfiltervmtest2' could actually be a replacement, no?
Yeah, but names that obvious are prone to DoS attacks. If you are
assuming bash, you can at least use $RANDOM to get past the worst of the
security hole in being that blatant. Or, as long as we are assuming
bash and linux, you could just skip the test if mktemp doesn't exist.

Ok, I'll change that.
No need - if you change this to be #!/bin/bash, then you are guaranteed
that [ ! -z "${line}" ] does the right thing, for all $line.

hurts my eyes :-)
They are equivalent, so I don't care (I'm just used to writing shell
script in as few characters as possible, such as a=$b rather than
a="${b}", both of which are semantically equivalent but one is 4 bytes
longer to type).

Good to know... will change even though the tests would not succeed on
Solaris.
I'll do a check using 'uname' to fail early on anything else than
'Linux'.
Once you've gone so far as to assume Linux, you can get away with a lot
of other assumptions (sed is decent, /bin/bash exists, ...). Then
again, I know that busybox prides itself on minimalistic POSIX
compliance, so it may be that busybox sed behaves like Solaris sed in
requiring text files (I don't know that for sure, though, as I seldom
target busybox).

I doesn't.
Huh. I guess I'll have to look into that.

Will change to bash, which will hopefully solve this issue.
Yeah, bash is immune to this particular problem. IIRC, it was zsh and
some proprietary /bin/sh.

Ok. Thanks for the review. Will adapt and re-post.
Well, one of the joys of open source is that you can have multiple
reviewers, each with different angles of expertise, with a cumulative
review better than any one person could give.

Alright, alright. I'll write a function that simulates mktemp if not
available using the ${RANDOM} suffix.
Though I hope nobody will DoS attack this test suite program :-)

Yeah, definitely a good thing.

This patch adds new test cases to the existing nwfilter test program

adds a test script that must be run while a VM is running. This test
script verifies that input network filter XML creates expected
user-defined tables and rules on ebtables, iptables & ip6tables layer
and verifies their content against expected content. The idea is that
these tools always return exactly the same output when displaying the
content of a user-defined table so that the diff tool can be used for
simple text comparison. All supported protocols have at least one test
case.
This test program is not run automatically since it requires a running
VM.
I think this test should really be part of the libvirt-TCK, since that
provides you the framework for running real VMs & interacting with the
host OS.
The tests in libvirt/tests should all be unit tests which don't interact
with the host system state
