5622830c53 Add mutex protection to SASL and TLS modules
The virNetSASLContext, virNetSASLSession, virNetTLSContext and
virNetTLSSession classes previously relied in their owners
(virNetClient / virNetServer / virNetServerClient) to provide
locking protection for concurrent usage. When virNetSocket
gained its own locking code, this invalidated the implicit
safety the SASL/TLS modules relied on. Thus we need to give
them all explicit locking of their own via new mutexes.

  a mutex per object

a44585972a Report error if unable to bind to any socket
When setting up a server socket, we must skip EADDRINUSE errors
from bind, since the IPv6 socket bind may have already bound to
the IPv4 socket too. If we don't manage to bind to any sockets
at all though, we should then report the EADDRINUSE error as
normal.

This fixes the case where libvirtd would not exit if some other
program was listening on its TCP/TLS ports.

4b7a8e9c0d virsh: make vcpucount use --current consistently
Rename the existing --current flag to the new name --active,
while adding a new flag --current to expose the new
VIR_DOMAIN_AFFECT_CURRENT flag of virDomainGetVcpusFlags.

For backwards compability, the output does not change (even
though the label "current" no longer matches the spelling of
the option that would trigger that number in isolation), and
we accept "--current --live" as an undocumented synonym for
"--active --live" to avoid breaking any existing clients.

* tools/virsh.c (cmdVcpucount): Add --active flag, and rearrange
existing flag handling to expose VIR_DOMAIN_AFFECT_CURRENT support.
* tools/virsh.pod (vcpucount): Document this.

59d042871c vcpu: teach getVcpusFlags about current
Now that virDomainSetVcpusFlags knows about VIR_DOMAIN_AFFECT_CURRENT,
so should virDomainGetVcpusFlags.

Unfortunately, the virsh counterpart 'virsh vcpucount' has already
commandeered --current for a different meaning, so teaching virsh
to expose this in the next patch will require a bit of care.

VIR_DOMAIN_AFFECT_CURRENT.

d6354c1696 util: change virFile*Pid functions to return < 0 on failure
Although most functions in libvirt return 0 on success and < 0 on
failure, there are a few functions lingering around that return errno
(a positive value) on failure, and sometimes code calling those
functions incorrectly assumes the <0 standard. I noticed one of these
the other day when auditing networkStartDhcpDaemon after Guido Gunther
found a place where success was improperly returned on failure (that
patch has been acked and is pending a push). The problem was that it
expected the return value from virFileReadPid to be < 0 on failure,
but it was actually positive (it was also neglected to set the return
code in this case, similar to the bug found by Guido).

This all led to the fact that *all* of the virFile*Pid functions in
util.c are returning errno on failure. This patch remedies that
problem by changing them all to return -errno on failure, and makes
any necessary changes to callers of the functions. (In the meantime, I
also properly set the return code on failure of virFileReadPid in
networkStartDhcpDaemon).

567b8d69b9 Fix TLS context tests with expired certs
commit 5283ea9b1d changed the
semantics of the 'expire_offset' field in the test case struct
so that instead of being an absolute timestamp, it was a delta
relative to the current time. This broke the test cases which
were testing expiry of certificates, by putting the expiry
time into the future, instead of in the past.

Fix this by changing the expiry values to be negative, so that
the delta goes into the past again.

2a667c34cb rename cfs_* to vcpu_*
In the XML file we now have

  <cputune>
    <shares>1024</shares>
    <period>90000</period>
    <quota>0</quota>
  </cputune>

But the schedinfo parameter are being named

 cpu_shares: 1024
 cfs_period: 90000
 cfs_quota: 0

The period/quota is per-vcpu value, so these new tunables should be named
'vcpu_period' and 'vcpu_quota'.

for burst (size) are just in kilobytes.

'network'.

239322cbd4 network: provide internal API to return IP of a network
The new listenNetwork attribute needs to learn an IP address based on a
named network. This patch provides a function networkGetNetworkAddress
which provides that.

Some networks have an IP address explicitly in their configuration
(ie, those with a forward type of "none", "route", or "nat"). For
those, we can just return the IP address from the config.

The rest will have a physical device associated with them (either via
<bridge name='...'/>, <forward ... dev='...'/>, or possibly via a pool
of interfaces inside the network's <forward> element) and we will need
to ask the kernel for a current IP address of that device (via the
newly added ifaceGetIPAddress)

If networkGetNetworkAddress encounters an error while trying to learn
the address for a network, it will return -1. In the case that libvirt
has been compiled without the network driver, the call is a macro
which reduces to -2. This allows differentiating between a failure of
the network driver, and its complete absence.

c5d1592e20 util: add an ifaceGetIPAddress to the interface utilities
This function uses ioctl(SIOCGIFADDR), which limits it to returning
the first IPv4 address of an interface, but that's what we want right
now (the place we're going to use the address only accepts one).

5283ea9b1d tests: fix compilation failures
Even though gnutls is a hard-req for libvirt, and gnutls depends
on libtasn1, that does not mean that you have to have the libtasn1
development files installed.  Skip the test rather than failing
compilation in that case.

With newer gcc, the test consumed too much stack space.  Move
things to static storage to fix that.

* configure.ac (AC_CHECK_HEADERS): Check for libtasn1.h.
(HAVE_LIBTASN1): New automake conditional.
* tests/Makefile.am (virnettlsconvirnettlscontexttest_SOURCES)

07f9b6f019 Allow certificate sanity checking to be disabled
When libvirtd starts it it will sanity check its own certs,
and before libvirt clients connect to a remote server they
will sanity check their own certs. This patch allows such
sanity checking to be skipped. There is no strong reason to
need to do this, other than to bypass possible libvirt bugs
in sanity checking, or for testing purposes.

libvirt.conf gains tls_no_sanity_certificate parameter to
go along with tls_no_verify_certificate. The remote driver
client URIs gain a no_sanity URI parameter

f7e18208e1 util: make interface.c functions consistently return < 0 on error
All of the functions in util/interface.c were returning 0 on success,
but some returned -1 on error, and some returned a positive value
(usually the value of errno, but sometimes just 1). Libvirt's standard
is to return < 0 on error (in the case of functions that need to
return errno, -errno is returned.

This patch modifies all functions in interface.c to consistently
return < 0 on error, and makes changes to callers of those functions
where necessary.
