This is needed if we want to transfer a temporary file. If the
transfer is done with iohelper, we might run into a race condition,
where we unlink() file before iohelper is executed.

We were 31/73 on whether to translate; since less than 50% translated
and since VIR_INFO is less than VIR_WARN which also doesn't translate,
this makes sense.

falls between WARN and DEBUG.

This matches the public API and helps to get rid of some special
case code in the remote generator.
Rename driver API functions and XDR protocol structs.
No functional change included outside of the remote generator.
Currently libvirt's default logging is limited and it is difficult to
determine what was happening when a proglem occurred (especially on a
machines where one don't know the detail.) This patch helps to do that
by making additional logging available for the following events:
creating/defining/undefining domains
creating/defining/undefining/starting/stopping networks
creating/defining/undefining/starting/stopping storage pools
creating/defining/undefining/starting/stopping storage volumes.
* AUTHORS: add Naoya Horiguchi
* src/network/bridge_driver.c src/qemu/qemu_driver.c
src/storage/storage_driver.c: provide more VIR_INFO logging
New APIs are added allowing streaming of content to/from
storage volumes.
* include/libvirt/libvirt.h.in: Add virStorageVolUpload and
virStorageVolDownload APIs
* src/driver.h, src/libvirt.c, src/libvirt_public.syms: Stub
code for new APIs
* src/storage/storage_driver.c, src/esx/esx_storage_driver.c:
Add dummy entries in driver table for new APIs
* .gnulib: Update to latest, for at least a stdint.h fix
* src/storage/storage_driver.c (storageVolumeZeroSparseFile)
(storageWipeExtent): Use better type, although it still triggers
spurious -Wformat warning on MacOS's gcc.
Many operations are not valid on inactive storage pools. The
storage driver is currently returning VIR_ERR_INTERNAL_ERROR
in these cases, rather than the more suitable error code
VIR_ERR_OPERATION_INVALID
* src/storage/storage_driver.c: Fix error code when pool
is not active
When libvirt starts up all storage pools default to the inactive
state, even if the underlying storage is already active on the
host. This introduces a new API into the internal storage backend
drivers that checks whether a storage pool is already active. If
the pool is active at libvirtd startup, the volume list will be
immediately populated.
* src/storage/storage_backend.h: New internal API for checking
storage pool state
* src/storage/storage_driver.c: Check whether a pool is active
upon driver startup
* src/storage/storage_backend_fs.c, src/storage/storage_backend_iscsi.c,
src/storage/storage_backend_logical.c, src/storage/storage_backend_mpath.c,
src/storage/storage_backend_scsi.c: Add checks for pool state
Using automated replacement with sed and editing I have now replaced all
occurrences of close() with VIR_(FORCE_)CLOSE() except for one, of
course. Some replacements were straight forward, others I needed to pay
attention. I hope I payed attention in all the right places... Please
have a look. This should have at least solved one more double-close
error.
The storage pool driver is mistakenly using the error code
VIR_ERR_INVALID_STORAGE_POOL which is for diagnosing invalid
pointers. This patch switches it to use VIR_ERR_NO_STORAGE_POOL
which is the correct code for cases where the storage pool does
not exist
* src/storage/storage_driver.c: Replace VIR_ERR_INVALID_STORAGE_POOL
with VIR_ERR_NO_STORAGE_POOL
The storage pool driver is not doing correct checking for
duplicate UUID/name values. This introduces a new method
virStoragePoolObjIsDuplicate, based on the previously
written virDomainObjIsDuplicate.
* src/conf/storage_conf.c, src/conf/storage_conf.c,
src/libvirt_private.syms: Add virStoragePoolObjIsDuplicate,
* src/storage/storage_driver.c: Call virStoragePoolObjIsDuplicate
for checking uniqueness of uuid/names
Spurious / in a pool target path makes life difficult for apps using the
GetVolByPath, and doing other path based comparisons with pools. This
has caused a few issues for virt-manager users:
https://bugzilla.redhat.com/show_bug.cgi?id=494005https://bugzilla.redhat.com/show_bug.cgi?id=593565
Add a new util API which removes spurious /, virFileSanitizePath. Sanitize
target paths when parsing pool XML, and for paths passed to GetVolByPath.
v2: Leading // must be preserved, properly sanitize path=/, sanitize
away /./ -> /
v3: Properly handle starting ./ and ending /.
v4: Drop all '.' handling, just sanitize / for now.
When trying to delete a pool the error message claimed the volume
could not be deleted.
* src/storage/storage_driver.c: Error message referred to
volumes instead of pools
The virConnectPtr is no longer required for error reporting since
that is recorded in a thread local. Remove use of virConnectPtr
from all APIs in storage_conf.{h,c} and storage_encryption_conf.{h,c}
and update all callers to match
In order to avoid problems trying to chown files that were created by
root on a root-squashing nfs server, fork a new process that setuid's
to the desired uid before creating the file. (It's only done this way
if the pool containing the new volume is of type 'netfs', otherwise
the old method of creating the file followed by chown() is used.)
This changes the semantics of the "create_func" slightly - previously
it was assumed that this function just created the file, then the
caller would chown it to the desired uid. Now, create_func does both
operations.
There are multiple functions that can take on the role of create_func:
createFileDir - previously called mkdir(), now calls virDirCreate().
virStorageBackendCreateRaw - previously called open(),
now calls virFileCreate().
virStorageBackendCreateQemuImg - use virRunWithHook() to setuid/gid.
virStorageBackendCreateQcowCreate - same.
virStorageBackendCreateBlockFrom - preserve old behavior (but attempt
chown when necessary even if not root)
* src/storage/storage_backend.[ch] src/storage/storage_backend_disk.c
src/storage/storage_backend_fs.c src/storage/storage_backend_logical.c
src/storage/storage_driver.c: change the create_func implementations,
also propagate the pool information to be able to detect NETFS ones.
* src/storage/storage_driver.c: Fix IsPersistent() and IsActivE()
methods on storage pools to use 'storagePrivateData' instead
of 'privateData'. Also fix naming convention of objects
Replace free(virBufferContentAndReset()) with virBufferFreeAndReset().
Update documentation and replace all remaining calls to free() with
calls to VIR_FREE(). Also add missing calls to virBufferFreeAndReset()
and virReportOOMError() in OOM error cases.

The LXC driver was mistakenly returning -1 for lxcStartup()
in scenarios that are not an error. This caused the libvirtd
to quit for unprivileged users. This fixes the return code
of LXC driver, and also adds a "name" field to the virStateDriver
struct and logging to make it easier to find these problems
in the future
* src/driver.h: Add a 'name' field to state driver to allow
easy identification during failures
* src/libvirt.c: Log name of failed driver for virStateInit
failures
* src/lxc/lxc_driver.c: Don't return a failure code for
lxcStartup() if LXC is not available on this host, simply
disable the driver.
