e19171b40c tools: Fix dry run of libvirt_recover_xattrs.sh
The libvirt_recover_xattrs.sh script can be used to remove stale
XATTRs that were left behind by secdrivers (which should happen
only if there's an imbalance between set and restore calls).
Anyway, the script has '-n' switch which is supposed to perform
just a dry run, i.e. just to report which files have XATTRs set
without any attempt to remove them.

But, when rewriting the script a few months ago a typo was
introduced which made the script report no files even if there
were files with XATTRs.

9b005b1967 vsh: Simplify condition for calling completer callback
The way we currently call completer callbacks is that if we've
found --option that user wants to complete value for and it has
callback set then the callback is called.

And just before that, if no --option to have the value completed
is found or is found and is of boolean type then a list of
--option is generated (for given command).

But these two conditions can never be true at the same time
because boolean type of --options do not accept values. Therefore
the calling of completer callback can be promoted onto the same
level as the --option list generation.

This means that merging of two lists can be dropped to and
completer callback can store its retval directly into @list (but
as shown earlier one of the string lists to merge is always
empty).

input (e.g. prefix of a domain name) and then use vshCompleterFilter() to

In contrast, vshReadlineCommandGenerator() does some internal filtering and

these scenarios differently, simply generate all possible options and
filter them all at the end.

3cc6572fab vsh: Rewrite opt->type check in vshReadlineParse()
The vshReadlineParse() function is called whenever user hits
<TAB><TAB>. If there is no command (or a partially written one),
then a list of possible commands is printed to the user. But, if
there is a command then its --options are generated. But
obviously, we can not generate --options if there already is an
--option that's expecting a value. For instance, consider:

  virsh # start --domain <TAB><TAB>

In this case we want to call completer for --domain option, but
that's a different story.

Anyway, the way that we currently check whether --options list
should be generated is checking the type of the last --option. If
it isn't DATA, STRING, INT, or ARGV (all these expect a value),
then we can generate --option list. Well, writing the condition
this way is needlessly verbose and also prone to errors (see
d9a320bf97 for example).

We know that boolean type does not require a value. This leaves
us with the only type that was not mentioned yet - VSH_OT_ALIAS.
This is a special type for backwards compatibility and it refers
to another --option which can be just any type.

6ba61373b7 vsh: Accept NULL @list in vshCompleterFilter()
The aim of vshCompleterFilter() is to take a string list and a
prefix and remove all strings from the list that don't have the
desired prefix. The function is used to filter out those strings
returned by a completer callback that don't correspond with
user's (partial) input. For instance, domain name completer
virshDomainNameCompleter() returns all domain names and then
vshCompleterFilter() refines the list so that only domains with
correct prefix of their name are offered to user. This was a
design choice - it allows us to have shorter completers as they
do not have to copy the list filtering over and over.

Having said all of that, it may happen that a completer does not
return anything (e.g. there is no domain in requested state,
virsh is not connected and thus completer exited early, etc.). In
that case, the string list is NULL and vshCompleterFilter() can
simply return early.

58aeebe096 vsh: Don't put VSH_OT_ALIAS onto list of completions
We've invented VSH_OT_ALIAS type for --option so that we can
rewrite some --options (e.g. fix spelling). For instance
blkdeviotune command uses this feature heavily:
--options-with-dash are preferred over old
--options_with_underscore. Both versions are supported but only
the new ones (not aliased) are documented and reported in --help.

Except for options completer, which happily put also aliased
versions in front of user's eyes.

Note, there is a second (gross) way we use aliases: to rewrite
options from --oldoption to --newoption=value (for instance
--shareable option of attach-disk is an alias of
--mode=shareable). And just like with the previous group - don't
generate them into the list of possible options.

b5e267e8c5 virsh: Simplify @flags handing in cmdSetmem() and cmdSetmaxmem()
What code tries to achieve is that if no flags were provided to
either 'setmem' or 'setmaxmem' commands then the old (no flags)
API is called to be able to communicate with older daemons.
Well, the code can be simplified a bit.

Note that with this change the old no flag version of APIs is
used more often. Previously if --current argument was given it
resulted in *Flags() version to be called even though it is not
necessary - VIR_DOMAIN_AFFECT_CURRENT is implied.

Therefore, this change in fact allows virsh to talk with broader
set of daemons. No other user visible changes were made.

b889594a70 tools: Set IFS for bash completion script
The way our bash completion string is that is gets user's input
and lets virsh completion code do all the work by calling 'virsh
complete -- $INPUT". The 'complete' command is a "secret",
unlisted command that exists solely for this purpose. After it
has done it's part, it prints candidates onto stdout, each
candidate on its own line, e.g. like this:

  # virsh complete -- "net-u"
  net-undefine
  net-update
  net-uuid

These strings are then stored into a bash array $A like this:

  A=($($1 ${CMDLINE} complete -- "${INPUT[@]}" 2>/dev/null))

This array is then thrown back at bash completion to produce
desired output. So far so good. Except, when there is an option
with space. For instance:

  # virsh complete -- start --domain ""
  uefi\ duplicate
  uefi

Bash interprets that as another array item because by default,
Internal Field Separator (IFS) = set of characters that bash uses
to split words at, is: space, TAB, newline. We don't want space
nor TAB. Therefore, we have to set $IFS when storing 'virsh

aad2262b9e vsh: Allow double quotes imbalance for auto completion in vshCommandStringGetArg()
If user is trying to auto complete a value that contains a space,
they have two options: use backslash to escape space or use
quotes, like this:

  virsh # start --domain "domain with space<TAB>

However, in this case our tokenizer sees imbalance in (double)
quotes: there is a starting one that's missing its companion.
Well, that's obvious - user is still in process of writing the
command. What we need to do in this case is to ignore the
imbalance and return success (from the tokenizer) - readline will
handle closing the quote properly.

22904b5702 vsh: Rework how option to complete is found
The way that auto completion works currently is that user's input
is parsed, and then we try to find the first --option (in the
parsed structure) that has the same value as user's input around
where <TAB> was pressed. For instance, for the following input:

  virsh # command --arg1 hello --arg2 world<TAB>

we will see "world" as text that user is trying to autocomplete
(this is affected by rl_basic_word_break_characters which
readline uses internally to break user's input into individual
words) and find that it is --arg2 that user is trying to
autocomplete. So far so good, for this naive approach. But
consider the following example:

  virsh # command --arg1 world --arg2 world<TAB>

Here, both arguments have the same value and because we see
"world" as text that user is trying to autocomplete we would
think that it is --arg1 that user wants to autocomplete. This is
obviously wrong.

Fortunately, readline stores the current position of cursor (into
rl_point) and we can use that when parsing user's input: whenever
we reach a position that matches the cursor then we know that
that is the place where <TAB> was pressed and hence that is the
--option that user wants to autocomplete. Readline stores the
cursor position as offset (numbered from 1) from the beginning of
user's input. We store this input into @parser->pos initially,
but then advance it as we tokenize it. Therefore, what we need is
to store the original position too.

Thanks to Martin who helped me with this.

f61a4e91ef vshReadlineParse: Escape list of candidates earlier
The way our completer callbacks work is that they return all
possible candidates and then vshCompleterFilter() is called to
prune the list of all candidates removing those which don't match
user's input. This allows us to have simpler completer callbacks
as their only job is to fetch all possible candidates.

Anyway, if the completion candidate we're returning contains a
space, it has to be escaped (shell like escaping), unless there
is already a quote character (single quote or double quote).

But ordering is critical. Completer callback returns string
without any escaping, but the filter function sees the user input
escaped. For instance, if user's input is "domain with
space<TAB>" then the filtering function gets "domain\ with\
space" as user's input but completer returns "domain with space".
Since these two strings don't match the filtering function
removes this candidate from the list. What we need to do is to
escape strings before calling the filtering function. This way,
the filtering function will see two same strings.

e19ecee54c vshReadlineParse: Bring some variables into !state block
On readline completion vshReadlineCompletion() is called which
does nothing more than calling rl_completion_matches() with
vshReadlineParse() as a callback. This means, that
vshReadlineParse() is called repeatedly, each time returning next
completion candidate, until it returns NULL which is interpreted
as the end of the list of candidates.

The function takes two parameters: @text which is a portion of
input line around cursor when TAB was pressed, and @state. The
@state is an integer that is zero on the very first call and
non-zero on each subsequent call (in fact, readline does @state++
on each call).

Anyway, the idea is that the callback gets the whole list of
candidates on @state == 0 and returns one candidate at each call.
And this is what vshReadlineParse() is doing but some variables
(@partial, @cmd and @opt) are really used only in the @state == 0
case but declared for whole function. We can limit their scope by
declaring them inside the @state == 0 body which also means that
they don't have to be static anymore.

b9dcaede65 virsh: cmdSetUserSSHKeys: Error early if the file doesn't contain any keys
When removing SSH keys via set-user-sshkeys virsh command, then
files to remove are read from passed file. But when
experimenting, I've passed /dev/null as the file which resulted
in API checks which caught that @keys argument of
virDomainAuthorizedSSHKeysSet() can't be NULL. This is because if
the file is empty then its content is an empty string and thus
the buffer the file was read in to is not NULL.

Long story short, error is reported correctly, but it's not
necessary to go through public API to catch it.

The comment that

Was correct at the time, but has since been addressed by
qemu/qemu@105fad6bb2, which added support for set-time without a time
argument, as used by `virsh domtime --sync` by libvirt-guests.sh.  I can
confirm that `virsh domtime --sync` works correctly on a Windows 10
guest, as does `SYNC_TIME=1`.  (Note that there can be a significant
delay between when the command completes and when the guest time
finishes synchronizing due to QEMU GA calling `w32tm` with `/nowait`,
which complicates testing.)

Using virtCgroupNewSelf() is not correct with cgroups v2 because the
the virt-host-validate process is executed from from the same cgroup
context as the terminal and usually not all controllers are enabled
by default.

To do a proper check we need to use the root cgroup to see what
controllers are actually available. Libvirt or systemd ensures that
all controllers are available for VMs as well.

This still doesn't solve the devices controller with cgroups v2 where
there is no controller as it was replaced by eBPF. Currently libvirt
tries to query eBPF programs which usually works only for root as
regular users will get permission denied for that operation.

8a4343a436 vsh: Fix completion error in case of multiple mac addresses
We know that the bash completer automatically handle colon by preceding
it with an escape character backslash.
While our bash autompletion file vsh completes multiple items, In case
there're multiple items which have same prefix and the content of completion
items contain colon(say mac address), The vsh needs to correctly hands
the backslash which are added by bash completer, Otherwise the completion
won't be successful. This patch fixes this problem.

e.g.:

 # virsh domiflist --domain VM

-------------------------------------------------------------
 vnet0       network   default   virtio   52:54:00:fb:7b:f5

 # virsh detach-interface --domain VM --mac <TAB>
 # virsh detach-interface --domain VM --mac 52\:54\:00\:<TAB><TAB>

After:

53aec799fa Include vdpa devices in node device list
The current udev node device driver ignores all events related to vdpa
devices. Since libvirt now supports vDPA network devices, include these
devices in the device list.

Example output:

virsh # nodedev-list
[...ommitted long list of nodedevs...]
vdpa_vdpa0

virsh # nodedev-dumpxml vdpa_vdpa0
<device>
  <name>vdpa_vdpa0</name>
  <path>/sys/devices/vdpa0</path>
  <parent>computer</parent>
  <driver>
    <name>vhost_vdpa</name>
  </driver>
  <capability type='vdpa'>
    <chardev>/dev/vhost-vdpa-0</chardev>
  </capability>
</device>

NOTE: normally the 'parent' would be a PCI device instead of 'computer',
but this example output is from the vdpa_sim kernel module, so it
doesn't have a normal parent device.

08f8fd8413 conf: Add support for vDPA network devices
This patch adds new schema and adds support for parsing and formatting
domain configurations that include vdpa devices.

vDPA network devices allow high-performance networking in a virtual
machine by providing a wire-speed data path. These devices require a
vendor-specific host driver but the data path follows the virtio
specification.

When a device on the host is bound to an appropriate vendor-specific
driver, it will create a chardev on the host at e.g.  /dev/vhost-vdpa-0.
That chardev path can then be used to define a new interface with
type='vdpa'.

a79e7639da build: eliminate useless WITH_VIRTUALPORT check
WITH_VIRTUALPORT just checks that we are building on Linux and that
IFLA_PORT_MAX is defined in linux/if_link.h. Back when 802.11Qb[gh]
support was added, the IFLA_* stuff was new (introduced in kernel
2.6.35, backported to RHEL6 2.6.32 kernel at some point), and so this
extra check was necessary, because libvirt was being built on Linux
distros that didn't yet have IFLA_* (e.g. older RHEL6, all
RHEL5). It's been in the kernel for a *very* long time now, so all
supported versions of all Linux platforms libvirt builds on have it.

Note that the above paragraph implies that the conditional compilation
should be changed to #if defined(__linux__). However, the astute
reader will notice that the code in question is sending and receiving
netlink messages, so it really should be conditional on WITH_LIBNL
(which implies __linux__) instead, so that's what this patch does.

caa9560c15 wireshark: Prefer ws_version.h over config.h
A wireshark plugin must declare what major and minor version it
was built with as these are checked when wireshark loads plugins.
On the top of that, we use major + minor + micro to adapt to
changed API between releases. So far, we were getting these
version numbers from wireshark/config.h.

And while most distributions install wireshark/config.h file some
don't. On distros shipping it it's hack^Wsaved during built by
packaging system and installed later. But some distros are not
doing that. At least not for new enough wireshark because as of
wireshark's commit v2.9.0~1273 the ws_version.h is installed
which contains the version macros we need and is installed by
wireshark itself.

But of course, some distros which have new enough wireshark
packaged do not ship ws_version.h and stick to the hack. That is
why we can't simply bump the minimal version and switch to the
new header file. We need a configure check and adopt our code to
deal with both ways. At least for the time being.

9e0ba037cd virshStreamInData: Handle block devices
This is very similar to previous commit.

The virshStreamInData() callback is used by virStreamSparseSendAll()
to detect whether the file the data is read from is in data or hole
section. The SendAll() will then send corresponding type of virStream
message to make server create a hole or write actual data. But the
callback uses virFileInData() even for block devices, which results in
an error. Just like in previous commit, emulate a DATA section
for block devices.

tools: fix libvirt-guests.sh text assignments
In libvirt 6.6 stopping guests with libvirt-guests.sh is broken.
As soon as there is more than one guest one can see
`systemctl stop libvirt-guests` failing and in the log we see:
  libvirt-guests.sh[2455]: Running guests on default URI:
  libvirt-guests.sh[2457]: /usr/lib/libvirt/libvirt-guests.sh: 120:
      local: 2a49cb0f-1ff8-44b5-a61d-806b9e52dae2: bad variable name
  libvirt-guests.sh[2462]: no running guests.

That is due do mutliple guests becoming a list of UUIDs. Without
recognizing this as one single string the assignment breaks when using 'local'
(which was recently added in 6.3.0). This is because local is defined as
  local [option] [name[=value] ... | - ]
which makes the shell trying handle the further part of the string as
variable names. In the error above that string isn't a valid variable
name triggering the issue that is seen.

This depends on the shell being used. POSIX shells don't have 'local'
specified yet and for the common shells it depends. It worked in bash and
bash-in-POSIX-mode, but for example dash in POSIX mode triggers the issue.

To resolve that 'textify' all assignments that are strings or potentially
can become such lists (even if they are not using the local qualifier).

ee247e1d3f Use g_strfeev instead of virStringFreeList
Both accept a NULL value gracefully and virStringFreeList
does not zero the pointer afterwards, so a straight replace
is safe.

e05487610c tools: virt-admin: do not leak daemon-log settings
The commands daemon-log-filters and daemon-log-outputs
are used both for getting and setting the variables.
But the getter receives an allocated string, which
we do not free.

Use separate variables for the getter and the setter
to get rid of the memory leak and to stop casting
away the const.

fc09f3d823 virsh: cmdBlock*: Remove 'error:' prefix for an empty line
When a block copy job fails prior to reaching the synchronized phase
while we are waiting for the job to finish virsh would print the
following:

 $ virsh blockcopy backup-test vda /tmp/dst.qcow2 --wait --reuse-external --transient-job
 error:
 Copy failed

The above message looks like we've forgot to print the error message
itself as the line ends after 'error:'. Unfortunately with the current
API design clients have no way of actually getting the error message as
the VIR_DOMAIN_EVENT_ID_BLOCK_JOB(_2) event only reports the status but
not an error and the job then vanishes.

Fix the expectations by using vshPrintExtra instead of vshError:

 $ virsh blockcopy backup-test vda /tmp/dst.qcow2 --wait --reuse-external --transient-job

 Copy failed

Note that the newline is required to avoid printing the 'Copy failed'
message on the same line when printing the job progress percentage.

Inspired by https://bugzilla.redhat.com/show_bug.cgi?id=1847867

Fix the same issue also for block pull and block commit job

dc0771cfa2 tools: rewrite interactive job monitoring logic
For long running jobs (save, managed save, dump & live migrate)
virsh runs a background thread for executing the job and then
has the main thread catch Ctrl-C for graceful shutdown, as well
as displaying progress info.

The monitoring code is written using poll, with a pipe used
to get the completion status from the thread. Using a pipe
and poll is problematic for Windows portability. This rewrites
the code to use a GMainLoop instance for monitoring stdin and
doing progress updates. The use of a pipe is entirely eliminated,
instead there is just a shared variable between both threads
containing the job completion status.

No mutex locking is used because the background thread writes
to the variable only when the main loop is still running,
while the foreground thread only reads it after the main loop
has exited.

At the same time, now that we have strings we need declared as
an enum we can use TypeToString() instead of copying strings.

79b9328d76 virsh: Use VIR_ENUM_* instead of open coding string -> enum conversion
There are more occurrences, but I'm converting --source argument
of domifaddr command only, because I will need it in next commit.

0b4598b183 src: replace getcwd() with g_get_current_dir()
commandhelper.c is not converted since this is a standalone
program only run on UNIX, so can rely on getcwd().

f5e9bdb87f src: replace clock_gettime()/gettimeofday() with g_get_real_time()
g_get_real_time() returns the time since epoch in microseconds.
It uses gettimeofday() internally while libvirt used clock_gettime
because it is declared async signal safe. In practice gettimeofday
is also async signal safe *provided* the timezone parameter is
NULL. This is indeed the case in g_get_real_time().

f7df985684 src: switch from fnmatch to g_pattern_match_simple
The g_pattern_match function_simple is an acceptably close
approximation of fnmatch for libvirt's needs.

In contrast to fnmatch(), the '/' character can be matched
by the wildcards, there are no '[...]' character ranges and
'*' and '?' can not be escaped to include them literally in
a pattern.
