63d3d895a2 virsh: Add/allow secret-uuid for pool-{define|create}-as
https://bugzilla.redhat.com/show_bug.cgi?id=1476775

For the virsh pool-{define|create}-as command, let's allow using
--secret-uuid on the command line as an alternative to --secret-usage
(added for commit id '8932580'), but ensure that they are mutually
 exclusive.

b06521928c storage: Add new events for *PoolBuild() and *PoolDelete().
This commit adds new events for two methods and operations: *PoolBuild() and
*PoolDelete(). Using the event-test and the commands set below we have the
following outputs:

$ sudo ./event-test
Registering event callbacks
myStoragePoolEventCallback EVENT: Storage pool test Defined 0
myStoragePoolEventCallback EVENT: Storage pool test Created 0
myStoragePoolEventCallback EVENT: Storage pool test Started 0
myStoragePoolEventCallback EVENT: Storage pool test Stopped 0
myStoragePoolEventCallback EVENT: Storage pool test Deleted 0
myStoragePoolEventCallback EVENT: Storage pool test Undefined 0

Another terminal:
$ sudo virsh pool-define test.xml
Pool test defined from test.xml

$ sudo virsh pool-build test
Pool test built

$ sudo virsh pool-start test
Pool test started

$ sudo virsh pool-destroy test
Pool test destroyed

$ sudo virsh pool-delete test
Pool test deleted

$ sudo virsh pool-undefine test
Pool test has been undefined

This commits can be a solution for RHBZ #1475227.

b616ec65e2 virsh: man: Describe the 'create' command a bit more
So we refer to the terms 'persistent' and 'transient' across the whole
man page, without describing it further, but more importantly, how the
create command affects it, i.e. explicitly stating that domain created
via the 'create' command are going to be transient or persistent,
depending on whether there is an existing persistent domain with a
matching <name> and <uuid>, in which case it will remain persistent, but
will run using a one-time configuration, otherwise it's going to be
transient and will vanish once destroyed.

ec91064169 wireshark: Adapt to tvb_new_subset() rename
In Wireshark commit of 7cd6906056922e4b8 (contained in v2.4.0)
the tvb_new_subset() function was renamed to
tvb_new_subset_length_caplen(). However, we can take the extra
step and rename to tvb_new_subset_remaining() directly (see
Wireshark commit 0ecfc7280cf3d7). The reasoning is that there is
no other protocol in the packet than libvirt. Therefore, from the
point that libvirt dissector takes over till the end of the
packet it's all libvirt packet.

2453501fc8 virsh: Track when create pkttyagent
https://bugzilla.redhat.com/show_bug.cgi?id=1374126

Due to how the processing for authentication using polkit works, the
virshConnect code must first "attempt" an virConnectOpenAuth and then
check for a "special" return error code VIR_ERR_AUTH_UNAVAILABLE in
order to attempt to "retry" the authentication after performing a creation
of a pkttyagent to handle the challenge/response for the client.

However, if pkttyagent creation is not possible for the authentication
being attempted (such as perhaps a "qemu+ssh://someuser@localhost/system"),
then the same failure pattern would be returned and another attempt to
create a pkttyagent would be done. This would continue "forever" until
someone forced quit (e.g. ctrl-c) from virsh as the 'authfail' was not
incremented when creating the pkttyagent.

So add a 'agentCreated' boolean to track if we've attempted to create the
agent at least once and force a failure if that creation returned the same
error pattern.

This resolves a possible never ending loop and will generate an error:

error: failed to connect to the hypervisor
error: authentication unavailable: no polkit agent available to authenticate action 'org.libvirt.unix.manage'

NB: If the authentication was for a sufficiently privileged client, such as
qemu+ssh://root@localhost/system, then the remoteDispatchAuthList "allows"
the authentication to use libvirt since @callerUid would be 0.

and parsing it along with error reporting.

Additionally a second helper also gets the domain object from the

a48c674fba storage: Move and rename disk backend label checking
Rather than have the Disk code having to use PARTED to determine if
there's something on the device, let's use the virStorageBackendDeviceProbe.
and only fallback to the PARTED probing if the BLKID code isn't built in.

This will also provide a mechanism for the other current caller (File
System Backend) to utilize a PARTED parsing algorithm in the event that
BLKID isn't built in to at least see if *something* exists on the disk
before blindly trying to use. The PARTED error checking will not find
file system types, but if there is a partition table set on the device,
it will at least cause a failure.

Move virStorageBackendDiskValidLabel and virStorageBackendDiskFindLabel
to storage_backend and rename/rework the code to fit the new model.

Update the virsh.pod description to provide a more generic description
of the process since we could now use either blkid or parted to find
data on the target device.

f23d4bbce3 storage: Fix implementation of no-overwrite for file system backend
https://bugzilla.redhat.com/show_bug.cgi?id=1363586

Commit id '27758859' introduced the "NO_OVERWRITE" flag check for
file system backends; however, the implementation, documentation,
and algorithm was inconsistent. For the "flag" description for the
API the flag was described as "Do not overwrite existing pool";
however, within the storage backend code the flag is described
as "it probes to determine if filesystem already exists on the
target device, renurning an error if exists".

The code itself was implemented using the paradigm to set up the
superblock probe by creating a filter that would cause the code
to only search for the provided format type. If that type wasn't
found, then the algorithm would return success allowing the caller
to format the device. If the format type already existed on the
device, then the code would fail indicating that the a filesystem
of the same type existed on the device.

The result is that if someone had a file system of one type on the
device, it was possible to overwrite it if a different format type
was specified in updated XML effectively trashing whatever was on
the device already.

This patch alters what NO_OVERWRITE does for a file system backend
to be more realistic and consistent with what should be expected when
the caller requests to not overwrite the data on the disk.

Rather than filter results based on the expected format type, the
code will allow success/failure be determined solely on whether the
blkid_do_probe calls finds some known format on the device. This
adjustment also allows removal of the virStoragePoolProbeResult
enum that was under utilized.

If it does find a formatted file system different errors will be
generated indicating a file system of a specific type already exists
or a file system of some other type already exists.

In the original virsh support commit id 'ddcd5674', the description
for '--no-overwrite' within the 'pool-build' command help output
has an ambiguous "of this type" included in the short description.
Compared to the longer description within the "Build a given pool."
section of the virsh.pod file it's more apparent that the meaning
of this flag would cause failure if a probe of the target already
has a filesystem.

So this patch also modifies the short description to just be the
antecedent of the 'overwrite' flag, which matches the API description.
This patch also modifies the grammar in virsh.pod for no-overwrite
as well as reworking the paragraph formats to make it easier to read.

The virsh manpage lists options --uuid and --name as
mutually exclusive along option --table when actually
the option --table is mutually exclusive and can't go
with options --uuid and/or --name. This patch rewords the
virsh manpage to state the correct meaning.

0289b8b2ba virsh: Display perf enabled/disabled message for set operations
When setting perf events, the enabled/disabled perf events are not
listed. Since we know which events were changed it's possible to
print out the values on successful set, such as :

    virsh perf Domain --enable instructions --disable cache_misses
    instructions   : enabled
    cache_misses   : disabled

Created a helper to print the messages - use the vshPrintExtra to
adhere to the --quiet|-q option being set by some script. This will
cause the get code to print nothing, but will return success/failure.

f62e418c86 virsh: Allow display of the physical volume size
Add a new qualifier '--physical' to the 'vol-info' command in order to
dispaly the physical size of the volume. The size can differ from the
allocation value depending on the volume file time. In particular, qcow2
volumes will have a physical value larger than allocation. This also occurs
for sparse files, although for those the capacity is the largest size;
whereas, for qcow2 capacity is the logical size.

22f7ceb695 nss: Introduce libvirt-guest module
So far the NSS module looks up only hostnames as provided by
guests themselves. However, there are some cases where this is
not enough: e.g. when there's a fresh new guest being installed
(with some generic hostname) say from a live ISO image; or some
(older) systems don't advertise their hostname in DHCP
transactions at all.
In cases like that it would be helpful if we translate domain
name as seen by libvirt too so that users can:

  # virsh start $dom && ssh $dom

In order to achieve that new libvirt-guest module is introduced,
while older libvirt module maintains its current behaviour (that
is translating guest provided names into IP addresses).

01079727fe libvirtd: systemd: add special target for system shutdown
It is already discussed in "[RFC] daemon: remove hardcode dep on libvirt-guests" [1].

Mgmt can use means to save/restore domains on system shutdown/boot other than
libvirt-guests.service. Thus we need to specify appropriate ordering dependency between
libvirtd, domains and save/restore service. This patch takes approach suggested
in RFC and introduces a systemd target, so that ordering can be built next way:

libvirtd -> domain -> virt-guest-shutdown.target -> save-restore.service.

This way domains are decoupled from specific shutdown service via intermediate
target.

b98b3b742b vsh: Drop conditional error reporting in vshErrorHandler
First, since commit 834c5720 the error reporting within the vshErrorHandler
doesn't work because there was a lot of renaming going on (dull mechanical
renaming without much thinking about it, yep - shame on me) and so the original
env variable VIRSH_DEBUG got renamed to VSH_DEBUG which we don't support nor
document anywhere. Second, by specifying this env variable, the last libvirt
error gets reported twice despite the fact we say the error reporting should be
deferred until the command finishes, and last but not least the vintage code's
logic is a bit 'odd', since the error would get reported iff the env variable
is set, even if the value should be equal to our DEFAULT value in which case it
doesn't make sense that we behave differently when an env variable is set to
some value and when there's no env variable at all but we use the same value
automatically as default.

Commit id 'dcfdf341' passes 'opts_need_arg' and 'opts_seen' to

Instead the static 'const_opts_need_arg' and 'const_opts_seen' values
should be passed.

By passing unitialized values leads to not finding possible options
for simpler commands (domfsfreeze for example), where if you're in
a virsh shell using command line completion - you'll get a list of
files in your current directory instead of two options --domain and
--mountpoint (as would happen with this patch applied.

2273bbd457 libvirt-guests: Weaken dependency on libvirtd
The Requires relationship is very strong, in that it prevents

This turns out to be a problem because we want to be able to
restart libvirtd at any time without having libvirt-guests
suspend or shutdown running guests.

Turn the Requires relationship into a Wants relationship:
this way starting libvirt-guests will cause systemd to (attempt
to) start libvirtd as well, but stopping or restarting libvirtd
will not alter libvirt-guests' running state.

bcfa2f427d vsh: Write out history on "quit" or "exit" in interactive mode
https://bugzilla.redhat.com/show_bug.cgi?id=1379895

Introduced by commit id '834c5720'.

During the code motion and creation of vsh.c, the function 'vshDeinit()'
in the (new) vsh.c was altered from whence it came in virsh.c such that
calling 'vshReadlineDeinit(ctl)' was conditional on "ctl->imode".

This causes a problem for the interactive running if the "quit" and "exit"
commands are used because 'cmdQuit' will clear ctl->imode, thus when the
interactive loop in main() of virsh.c exits because ctl->mode is clear and
virshDeinit is called which calls vshDeinit, the history file is now not
written. Conversely, if one had exited the interactive loop via pressing
<ctrl>D the file would be created because loop control is broken on EOF
and ctl->imode is not set to false.

This patch will remove the conditional call to vshReadlineDeinit and
restore the former behaviour.

Commit 6c504d6a added a note to the virsh man page about the
deprecation of 'cap' and 'weight' settings for the credit
scheduler. To this day, the default scheduler in Xen is credit
and it supports setting 'cap' and 'weight'. Remove the deprecation
notice from the note on the Xen credit scheduler.

b9d8cadeaa virt-admin: Tweak command parsing logic so that aliases point to new commands
Change the logic in a way, so that VSH_CMD_FLAG_ALIAS behaves similarly to
how VSH_OT_ALIAS for command options, i.e. there is no need for code duplication
for the alias and the aliased command structures. Along with that change,
switch any existing VSH_CMD_FLAG_ALIAS occurrences to this new format. Also,
since this patch introduces a new command structure element, adjust the
virsh-self-test test to make sure we won't ever miss to specify the '.alias'
member for an aliased command because doing that would lead to an internal
error.

This is similar to the work done for emulator quota and period by

Being able to view/set the IOThread specific values is related to more
recent changes adding global period (commmit id '4d92d58f') and global
quota (commit id '55ecdae') definitions and qemu support (commit id
'4e17ff79' and 'fbcbd1b2'). With a global setting though, if somehow
the IOThread value in the cgroup hierarchy was set "outside of libvirt"
to a value that is incompatible with the global value.

Allowing control over IOThread specific values provides the capability
to alter the IOThread values as necessary.

f5f32bcd1b admin: Fix default uri config option name s/admin_uri_default/uri_default
The original name 'admin_uri_default' was introduced to our code by commit
dbecb87f. However, at that time we already had a separate config file for
admin library but the commit mentioned above didn't properly adjust the
config's option name. The result is that when we're loading the config, we
check a non-existent config option (there's not much to do with the URIs
anyway, since we only allow local connection). Additionally, virt-admin's man
page documents, that the default URI can be altered by setting
admin_uri_default option. So the fix proposed by this patch leaves the
libvirt-admin.conf as is and adjusts the naming in the code as well as in the
virt-admin's man page.

0ef07e19c7 vsh: Make vshInitDebug return int instead of void
Well, the reason behind this change is that if the function is extended in some
way that e.g. would involve allocation we do not have a way of telling it to
the caller. More specifically, vshInitDebug only relies on some hardcoded
environment variables (by a mistake) that aren't documented anywhere so neither
virsh's nor virt-admin's documented environment variables take effect. One
possible solution would be duplicate the code for each CLI client or leave the
method be generic and provide means that it could figure out, which client
called it, thus initializing the proper environment variables but that could
involve operations that might as well fail in certain circumstances and the
caller should know that an error occurred.

bd93ba64fd vsh: Properly initialize res
The 'res' variable was only being initialized to NULL in the

res is assigned one of two results based on a pair of if then else if
conditions. If for some reason neither of those paths was taken and
the (!state) path wasn't taken, then 'res' would be indeterminate.

The virt-login-shell environment will be initialized with
an arbitrary number of environment variables determined
by the SSH daemon and PAM configuration. Most of these are
not relevant inside the container, and at best they are
noise and at worst they'll break apps. For example if
XDG_RUNTIME_DIR is leaked to the container, it'll break
any apps using it, since  the directory it points to is
only visible to the host OS filesystem, not the container
FS.

Use clearenv() to blank out everything and then set known
good values for PATH, SHELL, USER, LOGNAME HOME and TERM.
Everything else is left up to the login shell to initialize.

The standard way for login programs to request a shell run
as a login shell is to modify the argv passed to execve()
so that argv[0] contains the relative shell filename
prefixed with a zero. eg instead of doing

  const char **shellargs = ["/bin/bash", "-l", NULL];
  execve(shellargs[0], shellargs, env);

The virt-login-shell program is supposed to look like a

expect the shell to accept a '-c cmdstring' argument to
specify a command to launch instead of presenting an
interactive prompt.

We can implement this by simply passing the '-c cmdstring'
data straight through to the real shell we use. This does
not open any security holes, since the command is not run
until we're inside the container namespaces. This allows
scp to work for users with virt-login-shell.

Wire-up the public client listing API. Along with this change, a private time
simple conversion method to interpret client's timestamp obtained from server
has been added as well. Format used to for time output is as follows:
YYYY-mm-DD HH:MM:SS+ZZZZ.

Although libvirt exposes methods time-related methods through virtime.h
internally, it utilizes millisecond precision which we don't need in this case,
especially when connection timestamps use precision to seconds only.
This is just a convenience int to string conversion method.

To reflect the new API, man page has been adjusted accordingly.

0c56d94318 tools: Fix connect command
The man page says: "(Re)-Connect to the hypervisor. When the shell is
first started, this is automatically run with the URI parameter
requested by the "-c" option on the command line."  However, if you run:

  virsh -c 'test://default' 'connect; uri'

the output will not be 'test://default'.  That's because the 'connect'
command does not care about any virsh-only related settings and if it is
run without parameters, it connects with @uri == NULL.  Not only that
doesn't comply to what the man page describes, but it also doesn't make
sense.  It also means you aren't able to reconnect to whatever you are
connected currently.

So let's fix that in both virsh and virt-admin add a test case for it.

value with the one it tries to obtain from the VIRSH_DEFAULT_CONNECT_URI

This makes virsh connecting to the wrong URI if it disconnects from the
hypervisor and then tries to reconnect, and also leaks the original connname.

The result of processing is stored in a virBitmap, which
means we don't have to parse /proc/cpuinfo in its entirety
for each single CPU flag we want to check.

Moreover, use of the newly-introduced virHostValidateCPUFlag
enumeration ensures we don't go looking for random CPU flags
which might actually be simple typos.
