8e22e08935 build: rename files.h to virfile.h
In preparation for a future patch adding new virFile APIs.

* src/util/files.h, src/util/files.c: Move...
* src/util/virfile.h, src/util/virfile.c: ...here, and rename
functions to virFile prefix.  Macro names are intentionally
left alone.
* *.c: All '#include "files.h"' uses changed.
* src/Makefile.am (UTIL_SOURCES): Reflect rename.
* cfg.mk (exclude_file_name_regexp--sc_prohibit_close): Likewise.
* src/libvirt_private.syms: Likewise.

5d804ffae4 command: avoid leaking fds across fork
Since libvirt is multi-threaded, we should use FD_CLOEXEC as much
as possible in the parent, and only relax fds to inherited after
forking, to avoid leaking an fd created in one thread to a fork
run in another thread.  This gets us closer to that ideal, by
making virCommand automatically clear FD_CLOEXEC on fds intended
for the child, as well as avoiding a window of time with non-cloexec
pipes created for capturing output.

* src/util/command.c (virExecWithHook): Use CLOEXEC in parent.  In
child, guarantee that all fds to pass to child are inheritable.
(getDevNull): Use CLOEXEC.
(prepareStdFd): New helper function.
(virCommandRun, virCommandRequireHandshake): Use pipe2.
* src/qemu/qemu_command.c (qemuBuildCommandLine): Simplify caller.

4289114518 command: move all docs into .c file
We already have a precedent of function documentation in C files,
where it is closer to the implementation (witness libvirt.h vs.
libvirt.c); maintaining docs in both files risks docs going stale.

While I was at it, I used consistent doxygen style on all comments.

* src/util/command.h: Remove duplicate docs, and move unique
documentation...
* src/util/command.c: ...here.

fbd5465a5b rpc: Make the dispatch generator handle 'void name(void)' style procedures
The only 'void name(void)' style procedure in the protocol is 'close' that
is handled special, but also programming errors like a missing _args or
_ret suffix on the structs in the .x files can create such a situation by
accident. Making the generator aware of this avoids bogus errors from the
generator such as:

  Use of uninitialized value in exists at ./rpc/gendispatch.pl line 967.

Also this allows to get rid of the -c option and the special case code for
the 'close' procedure, as the generator handles it now correctly.

979b784be2 error: preserve errno when saving last error
It is common to see the sequence:

virErrorPtr save_err = virSaveLastError();
// do cleanup
virSetError(save_err);
virFreeError(save_err);

on cleanup paths.  But for functions where it is desirable to
return the errno that caused failure, this sequence can clobber
that errno.  virFreeError was already safe; this makes the other
two functions in the sequence safe as well, assuming all goes
well (on OOM, errno will be clobbered, but then again, save_err
won't reflect the real error that happened, so you are no longer
preserving the real situation - that's life with OOM).

* src/util/virterror.c (virSaveLastError, virSetError): Preserve
errno.

67a173c54f qemu: Implement cfs_period and cfs_quota's modification
This patch implements cfs_period and cfs_quota's modification.
We can use the command 'virsh schedinfo' to query or modify cfs_period and
cfs_quota.
If you query period or quota from config file, the value 0 means it does not set
in the config file.
If you set period or quota to config file, the value 0 means that delete current
setting from config file.
If you modify period or quota while vm is running, the value 0 means that use
current value.

b26a9fa9c2 undefine: Define the new API
This introduces a new API virDomainUndefineFlags to control the
domain undefine process, as the existing API virDomainUndefine
doesn't support flags.

Currently only flag VIR_DOMAIN_UNDEFINE_MANAGED_SAVE is supported.
If the domain has a managed save image, including
VIR_DOMAIN_UNDEFINE_MANAGED_SAVE in @flags will also remove that
file, and omitting the flag will cause undefine process to fail.

This patch also changes the behavior of virDomainUndefine, if the
domain has a managed save image, the undefine will be refused.

543c266d2d Add some basic sanity checking of certificates before use
If the libvirt daemon or libvirt client is configured with bogus
certificates, it is very unhelpful to only find out about this
when a TLS connection is actually attempted. Not least because
the error messages you get back for failures are incredibly
obscure.

This adds some basic sanity checking of certificates at the
time the virNetTLSContext object is created. This is at libvirt
startup, or when creating a virNetClient instance.

This checks that the certificate expiry/start dates are valid
and that the certificate is actually signed by the CA that is
loaded.

e06c8ede42 Add an explicit virNetClientClose method
Since the I/O callback registered against virNetSocket will
hold a reference on the virNetClient, we can't rely on the
virNetClientFree to be able to close the network connection.
The last reference will only go away when the event callback
fires (likely due to EOF from the server).

This is sub-optimal and can potentially cause a leak of the
virNetClient object if the server were to not explicitly
close the socket itself

  object when disconnecting

07b39a9418 Unregister event callback if a fatal error occurs during dispatch
If we get an I/O error in the async event callback for an RPC
client, we might not have consumed all pending data off the
wire. This could result in the callback being immediately
invoked again. At which point the same I/O might occur. And
we're invoked again. And again...And again...

Unregistering the async event callback if an error occurs is
a good safety net. The real error will be seen when the next
RPC method is invoked

33ba6e6881 libvirt: do not mix internal flags into public API
There were two API in driver.c that were silently masking flags
bits prior to calling out to the drivers, and several others
that were explicitly masking flags bits.  This is not
forward-compatible - if we ever have that many flags in the
future, then talking to an old server that masks out the
flags would be indistinguishable from talking to a new server
that can honor the flag.  In general, libvirt.c should forward
_all_ flags on to drivers, and only the drivers should reject
unknown flags.

In the case of virDrvSecretGetValue, the solution is to separate
the internal driver callback function to have two parameters
instead of one, with only one parameter affected by the public
API.  In the case of virDomainGetXMLDesc, it turns out that
no one was ever mixing VIR_DOMAIN_XML_INTERNAL_STATUS with
the dumpxml path in the first place; that internal flag was
only used in saving and restoring state files, which happened
to be in functions internal to a single file, so there is no
mixing of the internal flag with a public flags argument.
Additionally, virDomainMemoryStats passed a flags argument
over RPC, but not to the driver.

* src/driver.h (VIR_DOMAIN_XML_FLAGS_MASK)
(VIR_SECRET_GET_VALUE_FLAGS_MASK): Delete.
(virDrvSecretGetValue): Separate out internal flags.
(virDrvDomainMemoryStats): Provide missing flags argument.
* src/driver.c (verify): Drop unused check.

80cafba310 Fix now dead cleanup of VMs on libvirtd restart
When libvirtd restarts it will attempt to reconnect to existing
LXC containers. If it loads a XML state file for the container
the container will appear running. If we fail to read the PID
file, or fail to connect to the LXC monitor, we should be killing
off the guest, but if the VMs cgroup does not exist any more,
cleanup will get skipped. Reading the PID file is also pointless
since the PID is in the XML statefile

In lxcReconnectVM we do not need to read the PID file. If part
of the reconnect process fails we need to run the VM terminate
code as a safety net.

In lxcVMTerminate, if we can't obtain the VM cgroup, we know
the process has died, but we must still run lxcVMCleanup to
clear out the virDomainObjPtr live state

fab4f0c699 qemu: Fix a regression of attaching device
The regression is introduced by Commit da1eba6b, the new
codes with this commit doesn't reset "ret" to "-1" when
it fails on parsing the device XML (live device attachment)

This patch changes the codes to reset the "ret" and "-1",
and also changes the codes so that it don't modify "ret"
for condition checking.

How to reproduce:

% cat test.xml
<disk type='oops' device='disk'>
  <driver name='qemu' type='raw'/>
  <source file='/var/lib/libvirt/images/test.img'/>
  <target dev='vda' bus='virtio'/>
</disk>

% virsh attach-device $domain test.xml
Device attached successfully

The device attachment failed actually with error "unknown disk type 'oops'",
however, it reports success.

ca122578b3 esx: reject unknown flags
Silently ignored flags get in the way of new features that
use those flags.

Regarding ESX migration flags - right now, ESX silently enforces
VIR_MIGRATE_PERSIST_DEST, VIR_MIGRATE_UNDEFINE_SOURCE, and
VIR_MIGRATE_LIVE, even if those flags were not supplied; it ignored
other flags.  This patch does not change the implied bits (it permits
but does not require them), but enforces only the supported bits.
If further cleanup is needed to be more particular about migration
flags, that should be a separate patch.

* src/esx/esx_device_monitor.c (esxDeviceOpen): Reject unknown
flags.
* src/esx/esx_driver.c (esxOpen, esxDomainReboot)
(esxDomainXMLFromNative, esxDomainXMLToNative)
(esxDomainMigratePrepare, esxDomainMigratePerform)
(esxDomainMigrateFinish): Likewise.
* src/esx/esx_interface_driver.c (esxInterfaceOpen): Likewise.
* src/esx/esx_network_driver.c (esxNetworkOpen): Likewise.
* src/esx/esx_nwfilter_driver.c (esxNWFilterOpen): Likewise.
* src/esx/esx_secret_driver.c (esxSecretOpen): Likewise.
* src/esx/esx_storage_driver.c (esxStorageOpen): Likewise.

20135c704a flags: fix domain_conf migration regression
Commit 461e0f1a broke migration, because there was a code path
that tried to enable an internal flag while still going through
the public function.  Split the internal flag into a separate
callback, and validate that flags do not overlap.

* src/conf/domain_conf.c (virDomainDefFormat): Split...
(virDomainDefFormatInternal): ...to separate the flag check.
(virDomainObjFormat): Adjust caller.
