Anyway, the script has '-n' switch which is supposed to perform

without any attempt to remove them.

But, when rewriting the script a few months ago a typo was

Michal Privoznik 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).

Michal Privoznik 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.

Michal Privoznik 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.

Michal Privoznik 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.

What code tries to achieve is that if no flags were provided to

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.

Michal Privoznik 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
complete' output into the array.

Thanks to Peter who suggested it.

Michal Privoznik 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.

Michal Privoznik 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.

Michal Privoznik 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.

Michal Privoznik 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.

When removing SSH keys via set-user-sshkeys virsh command, then

Pavel Hrdina 126cb34a20 virt-host-validate: fix detection with cgroups v2
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.

Jonathon Jongsma 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.

Jonathon Jongsma 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'.

Laine Stump 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.

Michal Privoznik 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.

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

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).

Ján Tomko 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.

Ján Tomko d339113ab0 virt-login-shell: correctly calculate string length
virLoginShellGetShellArgv was not dereferencing the pointer

Ján Tomko 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.
