[libvirt] [PATCH 1/2] Allow certificate sanity checking to be disabled
by Daniel P. Berrange
From: "Daniel P. Berrange" <berrange(a)redhat.com>
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
* daemon/test_libvirtd.aug, daemon/libvirtd.conf,
daemon/libvirtd.c, daemon/libvirtd.aug: Add parameter to
allow cert sanity checks to be skipped
* src/remote/remote_driver.c: Add no_sanity parameter to
skip cert checks
* src/rpc/virnettlscontext.c, src/rpc/virnettlscontext.h:
Add new parameter for skipping sanity checks independantly
of skipping session cert validation checks

[libvirt] [PATCH] vcpu: teach getVcpusFlags about current
by Eric Blake
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 virsh does not
have a way to expose this new calling capability unless we either
break backward compatibility or consistency with other virsh commands
that take --live and --config.
* src/libvirt.c (virDomainGetVcpusFlags): Allow
VIR_DOMAIN_AFFECT_CURRENT.
* src/libxl/libxl_driver.c (libxlDomainGetVcpusFlags): Likewise.
* src/qemu/qemu_driver.c (qemudDomainGetVcpusFlags): Likewise.
* src/test/test_driver.c (testDomainGetVcpusFlags): Likewise.
* src/xen/xen_driver.c (xenUnifiedDomainGetVcpusFlags): Likewise.

[libvirt] [PATCH] util: change virFile*Pid functions to return < 0 on failure
by Laine Stump
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).
