As advertised in the previous commit, we need the list of
accessed files to also contain action that caused the $path to
appear on the list. Not only this enables us to fine tune our
white list rules it also helps us to see why $path is reported.
For instance:
/run/user/1000/libvirt/libvirt-sock: connect: qemuxml2argvtest: QEMU XML-2-ARGV net-vhostuser-multiq

The check-file-access.pl script is used to match access list
generated by virtestmock against whitelisted rules stored in
file_access_whitelist.txt. So far the rules are in form:
$path: $progname: $testname
This is not sufficient because the rule does not take into
account 'action' that caused $path to appear in the list of
accessed files. After this commit the rule can be in new form:
$path: $action: $progname: $testname
where $action is one from ("open", "fopen", "access", "stat",
"lstat", "connect"). This way the white list can be fine tuned to
allow say access() but not connect().

So far we are setting only fake secret and storage drivers.
Therefore if the code wants to call a public NWFilter API (like
qemuBuildInterfaceCommandLine() and qemuBuildNetCommandLine() are
doing) the virGetConnectNWFilter() function will try to actually
spawn session daemon because there's no connection object set to
handle NWFilter driver.
Even though I haven't experienced the same problem with the rest
of the drivers (interface, network and node dev), the reasoning
above can be applied to them as well.

Semantically, there is no difference between an uninitialized worker
pool and an initialized worker pool with zero workers. Let's allow the
worker pool to be initialized for max_workers=0 as well then which
makes the API more symmetric and simplifies code. Validity of the
worker pool is delegated to virThreadPoolGetMaxWorkers instead.
This patch fixes segmentation faults in
virNetServerGetThreadPoolParameters and
virNetServerSetThreadPoolParameters for the case when no worker pool
is actually initialized (max_workers=0).

Currently iohelper's error log is recorded in virFileWrapperFdClose.
However, if something goes wrong the caller might not even get to
calling virFileWrapperFdClose and call virFileWrapperFdFree
directly. Therefore the error reporting should happen there.

This proves libvirt can now handle high socket_id and
core_id values correctly and ensures we won't introduce
regressions in this area.
Signed-off-by: Andrea Bolognani <abologna@redhat.com>
While in most cases the values are going to be much
smaller than our arbitrary 4096 limit, there is really
no guarantee that would be the case: in fact, a few
aarch64 servers have been spotted in the wild with
core_id as high as 6216.
Take advantage of virBitmap's ability to automatically
alter its size at runtime to accomodate such values.

The latter are no longer used by libvirt, and the former
never were; moreover, both have a corresponding *_list
file which we can manipulate very conveniently using our
bitmap APIs, so dropping them makes sure in the future
developers will look into that rather than trying to
parse the kernel binary bitmaps.
Signed-off-by: Andrea Bolognani <abologna@redhat.com>
We already have a function which parses
thread_siblings_list for a CPU and returns the
corresponding bitmap, and a bunch of utility functions
that perform operations on bitmaps such as counting
the number of set bits: use those to implement the
function instead of having an additional ad-hoc parser
for thread_siblings.
