When receiving multiple FDs from systemd during service activation it is
neccessary to identify which purpose each FD is used for. While this
could be inferred by looking for the specific IP ports or UNIX socket
paths, this requires the systemd config to always match what is expected
by the code. Using systemd FD names we can remove this restriction and
simply identify FDs based on an arbitrary name.
The FD names are passed by systemd in the LISTEN_FDNAMES env variable
which is populated with the socket unit file names, unless overriden
by using the FileDescriptorName setting.
This is supported since the system 227 release and unfortunately RHEL7
lacks this version. Thus the code has some back compat support whereby
we look at the TCP ports or the UNIX socket paths to identify what
socket maps to which name. This back compat code is written such that
is it easly deleted when we are able to mandate newer systemd.

Way back in the past, the "no_tty=1" option was added for the remote
driver to disable local password prompting by disabling use of the local
tty:
commit b32f429849
Author: Daniel P. Berrange <berrange@redhat.com>
Date: Fri Sep 21 20:17:09 2007 +0000
Added a no_tty param to remote URIs to stop SSH prompting for password
This was done by adding "-T -o BatchMode=yes -e none" args to ssh. This
achieved the desired results but is none the less semantically flawed
because it is mixing up config parameters for the local tty vs the
remote tty.
The "-T" arg stops allocation of a TTY on the remote host. This is good
for all libvirt SSH tunnels as we never require a TTY for our usage
model, so we should have just passed this unconditionally.
The "-e none" option disables the escape character for sessions with a
TTY. If we pass "-T" this is not required, but it also not harmful to
add it, so we should just pass it unconditionally too.
Only the "-o BatchMode=yes" option is related to disabling local
password prompts and thus needs control via the no_tty URI param.

We've been doing a terrible job of performing XML validation in our
various API that parse XML with a corresponding schema (we started
with domains back in commit dd69a14f, v1.2.12, but didn't catch all
domain-related APIs, didn't document the use of the flag, and didn't
cover other XML). New APIs (like checkpoints) should do the validation
unconditionally, but it doesn't hurt to continue retrofitting existing
APIs to at least allow the option.
While there are many APIs that could be improved, this patch focuses
on wiring up a new snapshot XML creation flag through all the
hypervisors that support snapshots, as well as exposing it in 'virsh
snapshot-create'. For 'virsh snapshot-create-as', we blindly set the
flag without a command-line option, since the XML we create from the
command line should generally always comply (note that validation
might cause failures where it used to succeed, such as if we tighten
the RNG to reject a name of '../\n'); but blindly passing the flag
means we also have to add in fallback code to disable validation if
the server is too old to understand the flag.

This effectively reverts d7420430ce and adds new code.
Here is the problem: Imagine a file X that is to be shared
between two domains as a disk. Let the first domain (vm1) have
seclabel remembering turned on and the other (vm2) has it turned
off. Assume that both domains will run under the same user, but
the original owner of X is different (i.e. trying to access X
without relabelling leads to EPERM).
Let's start vm1 first. This will cause X to be relabelled and to
gain new attributes:
trusted.libvirt.security.ref_dac="1"
trusted.libvirt.security.dac="$originalOwner"
When vm2 is started, X will again be relabelled, but since the
new label is the same as X already has (because of vm1) nothing
changes and vm1 and vm2 can access X just fine. Note that no
XATTR is changed (especially the refcounter keeps its value of 1)
because the vm2 domain has the feature turned off.
Now, vm1 is shut off and vm2 continues running. In seclabel
restore process we would get to X and since its refcounter is 1
we would restore the $originalOwner on it. But this is unsafe to
do because vm2 is still using X (remember the assumption that
$originalOwner and vm2's seclabel are distinct?).
The problem is that refcounter stored in XATTRs doesn't reflect
the actual times a resource is in use. Since I don't see any easy
way around it let's just not store original owner on shared
resources. Shared resource in world of domain disks is:
- whole backing chain but the top layer,
- read only disk (we don't require CDROM to be explicitly
marked as shareable),
- disk marked as shareable.

One of the functions of this mock is that it spoofs chown() and

new owner on chown() and reports it on subsequent stat(). This is
done by using a 32bit unsigned integer where one half is used to
store uid the other is for gid. Later, when stat() is called the
integer is fetched and split into halves again. Well, my bit
operation skills are poor and the code I've written does not do

This test is beautiful. It checks if we haven't messed up
refcounting on security labels (well, XATTRs where the original
owner is stored). It does this by setting up tracking of XATTR
setting/removing into a hash table, then calling
qemuSecuritySetAllLabel() followed by immediate
qemuSecurityRestoreAllLabel() at which point, the hash table must
be empty. The test so beautifully written that no matter
what you do it won't fail. The reason is that all seclabel work
is done in a child process. Therefore, the hash table in the
parent is never changed and thus always empty.
There are two reasons for forking (only one of them makes sense
here though):
1) namespaces - when chown()-ing a file we have to fork() and
make the child enter desired namespace,
2) locking - because of exclusive access to XATTRs we lock the
files we chown() and this is done in a fork (see 207860927a for
more info).
While we want to fork in real world, we don't want that in a test
suite. Override virProcessRunInFork() then.

Hosts for rbd are ceph monitor daemons. These have fixed IP addresses,
so they are often referenced by IP rather than hostname for
convenience, or to avoid relying on DNS. Using IPv4 addresses as the
host name works already, but IPv6 addresses require rbd-specific
escaping because the colon is used as an option separator in the
string passed to librados.
Escape these colons, and enclose the IPv6 address in square brackets
so it is distinguished from the port, which is currently mandatory.

two capabilities as the two uses are orthogonal (full backups don't

Fortunately the use cases adding those flags in the past are rare, but
they exist. One that I identified are e.g. older virt-install when used
with --cpu=host-model and there always could be the case of a user
adding it to the guest xml.
This triggers an issue like:

Ports allocated on virtual networks with type=nat|route|open all get
given an actual type of 'network'.
Only ports in networks with type=bridge use an actual type of 'bridge'.
This distinction makes little sense since the virtualization drivers
will treat both actual types in exactly the same way, as they're all
just bridge devices a VM needs to be connected to.
This doesn't affect user visible XML since the "actual" device XML
is internal only, but we need code to convert the data upgrades.

The virNetDevBandwidthParse method uses the interface type to decide
whether to allow use of the "floor" parameter. Using the interface

None of the existing drivers actually use the 0-valued 'nostate'
snapshot state; rather, it was a fluke of implementation. In fact,
some drivers, like qemu, actively reject 'nostate' as invalid during a
snapshot redefine. Normally, a driver computes the state post-parse
from the current domain, and thus virDomainSnapshotGetXMLDesc() will
never expose the state. However, since the testsuite lacks any
associated domain to copy state from, and lacks post-parse processing
that normal drivers have, the testsuite output had several spots with
the state, coupled with a regex filter to ignore the oddity.
It is better to follow the lead of other XML defaults, by not
outputting anything during format if post-parse defaults have not been
applied, and rejecting the default value during parsing. The testsuite
needs a bit of an update, by adding another flag for when to simulate
a post-parse action of setting a snapshot state, but none of the
drivers are impacted other than rejecting XML that was previously
already suspicious in nature.
Similarly, don't expose creation time 0 (for now, only possible if a
user redefined a snapshot to claim creation at the Epoch, but also
happens once setting the creation time is deferred to a post-parse
handler).
This is also a step towards cleaning up snapshot_conf.c to separate
its existing post-parse work (namely, setting the creationTime and
default snapshot name) from the pure parsing work, so that we can get
rid of the testsuite hack of regex filtering of the XML and instead
have more accurate testing of our parser/formatter code.

Upcoming changes want to separate out a post-parse massaging of
snapshots separate from parsing the XML, so as not to be dependent on
filtering out an ever-changing timestamp from the testsuite. Along the
way, this means we will want to add yet another conditional to the
snapshot xml2xml tests on whether to perform post-processing steps to
canned values. This will be easier to read if we consolidate all the
decisions into a flags variable, instead of adding yet another
boolean.
While at it, drop the redundant inout test of "noparent" (once is
enough).

The python code is inlined rather than provided in a separate script
because whenever there's an issue with proper detection of CPU features,

Quite a few of the tests have a need to mock the stat() / lstat()
functions and they are taking somewhat different & inconsistent
approaches none of which are actually fully correct. This is shown
by fact that 'make check' fails on 32-bit hosts. Investigation
revealed that the code was calling into the native C library impl,
not getting intercepted by our mocks.
The POSIX stat() function might resolve to any number of different
symbols in the C library.
The may be an additional stat64() function exposed by the headers
too.
On 64-bit hosts the stat & stat64 functions are identical, always
refering to the 64-bit ABI.
On 32-bit hosts they refer to the 32-bit & 64-bit ABIs respectively.
Libvirt uses _FILE_OFFSET_BITS=64 on 32-bit hosts, which causes the
C library to transparently rewrite stat() calls to be stat64() calls.
Libvirt will never see the 32-bit ABI from the traditional stat()
call. We cannot assume this rewriting is done using a macro. It might
be, but on GLibC it is done with a magic __asm__ statement to apply
the rewrite at link time instead of at preprocessing.
In GLibC there may be two additional functions exposed by the headers,
__xstat() and __xstat64(). When these exist, stat() and stat64() are
transparently rewritten to call __xstat() and __xstat64() respectively.
The former symbols will not actally exist in the library at all, only
the header. The leading "__" indicates the symbols are a private impl
detail of the C library that applications should not care about.
Unfortunately, because we are trying to mock replace the C library,
we need to know about this internal impl detail.
With all this in mind the list of functions we have to mock will depend
on several factors
- If _FILE_OFFSET_BITS is set, then we are on a 32-bit host, and we
only need to mock stat64 and __xstat64. The other stat / __xstat
functions exist, but we'll never call them so they can be ignored
for mocking.
- If _FILE_OFFSET_BITS is not set, then we are on a 64-bit host and
we should mock stat, stat64, __xstat & __xstat64. Either may be
called by app code.
- If __xstat & __xstat64 exist, then stat & stat64 will not exist
as symbols in the library, so the latter should not be mocked.
The same all applies to lstat()
These rules are complex enough that we don't want to duplicate them
across every mock file, so this centralizes all the logic in a helper
file virmockstathelper.c that should be #included when needed. The
code merely need to provide a filename rewriting callback called
virMockStatRedirect(). Optionally VIR_MOCK_STAT_HOOK can be defined
as a macro if further processing is needed inline.

Introduced in fdf6c89ee7, this dependency looks weird. It was
needed because of the way that while() loop was written - it
fetches next argument in every iteration. Therefore, our only
option was for ARG_END to have the same value as QEMU_CAPS_LAST.
This also meant that QEMU_CAPS_* could have been only at the end
of the __VA_ARGS__.
This commit reworks the while() loop and removes the dependency.

There is one specific caller (testInfoSetArgs() in
qemuxml2argvtest.c) which expect the va_list argument to change
after returning from the virQEMUCapsSetVAList() function.
However, since we are passing plain va_list this is not
guaranteed. The man page of stdarg(3) says:
If ap is passed to a function that uses va_arg(ap,type), then
the value of ap is undefined after the return of that function.
(ap is a variable of type va_list)
I've seen this in action in fact: on i686 the qemuxml2argvtest
fails on the second test case because testInfoSetArgs() sees
ARG_QEMU_CAPS and calls virQEMUCapsSetVAList to process the
capabilities (in this case there's just one
QEMU_CAPS_SECCOMP_BLACKLIST). But since the changes are not
reflected in the caller, in the next iteration testInfoSetArgs()
sees the QEMU capability and not ARG_END.

The individual qemuDomainDetach*Device() functions will soon be "less
functional", since some of the code that is duplicated in 10 of the 12
detach functions is going to be moved into the common
qemuDomainDetachDeviceLive(), which calls them all.
qemuhotplugtest.c is the only place any of these individual functions
is called other than qemuDomainDetachDeviceLive() itself. Fortunately,
qemuDomainDetachDeviceLive() provides exactly the functionality needed
by the test driver (except that it supports detach of more device
types than the test driver has tests for).
This patch replaces the calls to
qemuDomainDetach(Chr|Shmen|Watchdog|Disk)Device with a single call to
the higher level function, allowing us to shift functionality between
the lower level functions without breaking the tests.

Had this been in place earlier, I would have avoided the bugs in
commit 0baf6945 and 55c2ab3e. Writing the test required me to extend
the power of virsh - creating enough snapshots to cause fanout
requires enough input in a single session that adding comments and
markers makes it easier to check that output is correct. It's still a
bit odd that with test:///default, reverting to a snapshot changes the
domain from running to paused (possibly a bug in how the test driver
copied from the qemu driver) - but the important part is that the test
is reproducible, and any future tweaks we make to snapshot code have
less chance of breaking successful command sequences.

As the previous commit mentioned, argv mode (such as when you feed
virsh via stdin with <<\EOF instead of via a single shell argument)
didn't permit comments. Do this by treating any command name token
that starts with # as a comment which silently eats all remaining
arguments to the next newline or semicolon.
Note that batch mode recognizes unquoted # at the start of any word as
a command as part of the tokenizer, while this patch only treats # at
the start of the command word as a comment (any other # remaining by
the time vshCommandParse() is processing things was already quoted
during the tokenzier, and as such was probably intended as the actual
argument to the command word earlier in the line).
Now I can do something like:
$ virsh -c test:///default <<EOF
# setup
snapshot-create-as test s1
snapshot-create-as test s2
# check
snapshot-list test --name

The only use for the 'current' member of virDomainSnapshotDef was with
the PARSE/FORMAT_INTERNAL flag for controlling an internal-use
<active> element marking whether a particular snapshot definition was
current, and even then, only by the qemu driver on output, and by qemu
and test driver on input. But this duplicates vm->snapshot_current,
and gets in the way of potential simplifications to have qemu store a
single file for all snapshots rather than one file per snapshot. Get
rid of the member by adding a bool* parameter during parse (ignored if
the PARSE_INTERNAL flag is not set), and by adding a new flag during
format (if FORMAT_INTERNAL is set, the value printed in <active>
depends on the new FORMAT_CURRENT).
Then update the qemu driver accordingly, which involves hoisting
assignments to vm->current_snapshot to occur prior to any point where
a snapshot XML file is written (although qemu kept
vm->current_snapshot and snapshot->def_current in sync by the end of
the function, they were not always identical in the middle of
functions, so the shuffling gets a bit interesting). Later patches
will clean up some of that confusing churn to vm->current_snapshot.
Note: even if later patches refactor qemu to no longer use
FORMAT_INTERNAL for output (by storing bulk snapshot XML instead), we
will always need PARSE_INTERNAL for input (because on upgrade, a new
libvirt still has to parse XML left from a previous libvirt).

virDomainSnapshotDefFormat currently takes two sets of knobs:
an 'unsigned int flags' argument that can currently just be
VIR_DOMAIN_DEF_FORMAT_SECURE, and an 'int internal' argument used as
a bool to determine whether to output an additional element. It
then reuses the 'flags' knob to call into virDomainDefFormatInternal(),
which takes a different set of flags. In fact, prior to commit 0ecd6851
(1.2.12), the 'flags' argument actually took the public
VIR_DOMAIN_XML_SECURE, which was even more confusing. Let's borrow
from the style of that earlier commit, by introducing a function
for translating from the public flags (VIR_DOMAIN_SNAPSHOT_XML_SECURE
was just recently introduced) into a new enum specific to snapshot
formatting, and adjust all callers to use snapshot-specific enum
values when formatting, and where the formatter now uses a new
variable 'domainflags' to make it obvious when we are translating
from snapshot flags back to domain flags. We don't even have to
use the conversion function for drivers that don't accept the
public VIR_DOMAIN_SNAPSHOT_XML_SECURE flag.

While this function is not, strictly speaking, a predicate,
it still mostly behaves like one as evidenced by the vast

the return type makes sense.

It may happen that both symbols are present. Especially when
chaining mocks. For instance if a test is using virpcimock and
then both stat and __xstat would be present in the address space
as virpcimock implements both. Then, if the test would try to use
say virfilewrapper (which again uses VIR_MOCK_REAL_INIT_ALT() to
init real_stat and real___xstat) it would find stat() from
virpcimock and stop there. The virfilewrapper.c:real___xstat
wouldn't be initialized and thus it may result in a segfault.
The reason for segfault is that sys/stat.h may redefine stat() to
call __xstat().

dnsmasq documentation says that the *IPv4* prefix/network
address/broadcast address sent to dhcp clients will be automatically
determined by dnsmasq by looking at the interface it's listening on,
so the original libvirt code did not add a netmask to the dnsmasq
commandline (or later, the dnsmasq conf file).
For *IPv6* however, dnsmasq apparently cannot automatically determine
the prefix (functionally the same as a netmask), and it must be
explicitly provided in the conf file (as a part of the dhcp-range
option). So many years after IPv4 DHCP support had been added, when
IPv6 dhcp support was added the prefix was included at the end of the
dhcp-range setting, but only for IPv6.
A user had reported a bug on a host where one of the interfaces was a
superset of the libvirt network where dhcp is needed (e.g., the host's
ethernet is 10.0.0.20/8, and the libvirt network is 10.10.0.1/24). For
some reason dnsmasq was supplying the netmask for the /8 network to
clients requesting an address on the /24 interface.
This seems like a bug in dnsmasq, but even if/when it gets fixed
there, it looks like there is no harm in just always adding the
netmask to all IPv4 dhcp-range options similar to how prefix is added
to all IPv6 dhcp-range options.

Add a explicit format when starting the VM and format is not present

Post parse callback adds the 'raw' type only for local files. Remote
files can also have backing store (even local) so we should do this also
for network backed storage.
Note that virStorageFileGetMetadata always considers files with no type
as raw so we will not accidentally traverse the backing chain and allow
unexpected files being labelled with svirt labels.

In commit f80eae8c2a I was too agresive in removing properties of
-drive for empty drives. It turns out that qemu actually persists the
state of 'readonly' and the throttling information even for the empty
drive.
Removing 'readonly' thus made qemu open any subsequent images added via
the 'change' command as RW which was forbidden by selinux thanks to the
restrictive sVirt label for readonly media.
Fix this by formating the property again and bump the tests and leave a
note detailing why the rest of the properties needs to be skipped.

Since we already were able to start a VM with such config previously due
to qemu ignoring them I've opted just to skip formatting them.
Additionally with -blockdev support it will work as expected as the

backend specific module into a common storage_util module causes

So instead of assuming they are there, let's just pass the command
string to the storage util API's from the storage backend specific
code (as would have been successful before). Also modify the test
to determine whether the MOUNT and/or VGCHANGE doesn't exist and
just define it to (for example) what Fedora has for the path. Could

In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.
In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.
With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to find the
author of a particular bit of code.
This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.
The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

There are two ways to request memory preallocation on cmd line:
-mem-prealloc and .prealloc attribute for a memory-backend-file.
However, as it turns out it's not safe to use both at the same
time. If -mem-prealloc is used then qemu will fully allocate the
memory (this is done by actually touching every page that has
been allocated). Then, if .prealloc=yes is specified,
mbind(flags = MPOL_MF_STRICT | MPOL_MF_MOVE) is called which:
a) has to (possibly) move the memory to a different NUMA node,
b) can have no effect when hugepages are in play (thus ignoring user
request to place memory on desired NUMA nodes).
Prefer -mem-prealloc as it is more backward compatible
compared to switching to "-numa node,memdev= + -object

The QEMU validation code for graphics has been in place for a while, but
because it is only executed from virDomainDeviceInfoIterateInternal, it
was never run, since the iterator expects the device to have boot info
which graphics don't have. The unfortunate side effect of this whole mess
was that a few capabilities were missing from the test suite (as commit
d8266ebe1 demonstrated with graphics-spice-invalid-egl-headless test),
which in turn meant that a few graphics tests which expected a failure
happily accepted any failure the test runtime returned which made them
succeed. The impact of this was that we then allowed to start a domain
with multiple OpenGL-enabled graphics devices.
This patch enables iteration over graphics devices. Unsurprisingly,

The networkxml2firewalltest sets virCommand to dry run mode but doesn't
provide a callback to fill in stdout/stderr. As a result when the
firewall code queries rules it gets a NULL output and so never triggers
the callback to process output.
This trivial change just returns an empty string for the command output
in order to ensure the callback gets triggered. It has no effect right
now, but in future patches this will trigger greater test coverage.

Up until now, we formatted 'rendernode=' onto QEMU cmdline only if the

Add a new memoryBacking source type "memfd", supported by QEMU (when
the capability is available).
A memfd is a specialized anonymous memory kind. As such, an anonymous
source type could be automatically using a memfd. However, there are
some complications when migrating from different memory backends in
qemu (mainly due to the internal object naming at this point, but
there could be more). For now, it is simpler and safer to simply
introduce a new source type "memfd". Eventually, the "anonymous" type
could learn to use memfd transparently in a separate change.
The main benefits are that it doesn't need to create filesystem files,
and it also enforces sealing, providing a bit more safety.

The URI parser used by libvirt does not populate uri->path if the
trailing slash is missing. The code virStorageSourceParseBackingURI
would then not populate src->path.
As only NBD network disks are allowed to have the 'name' field in the
XML defining the disk source omitted we'd generate an invalid XML which
we'd not parse again.
Fix it by populating src->path with an empty string if the uri is
lacking slash.
As pointed out above NBD is special in this case since we actually allow
it being NULL. The URI path is used as export name. Since an empty
export does not make sense the new approach clears the src->path if the
trailing slash is present but nothing else.
Add test cases now to cover all the various cases for NBD and non-NBD
uris as there was to time only 1 test abusing the quirk witout slash for
NBD and all other URIs contained the slash or in case of NBD also the
export name.

Commit 4f4c3b13 (v3.3) fixed an issue where performing cleanup of
libvirt objects could sometimes lose error messages, by adding code
to copy the libvirt error into last_error prior to cleanup paths.
However, it caused a regression: on other paths, some errors are now
printed twice, if libvirt still remembers in its thread-local
storage that an error was set even after virsh cleared last_error.
For example:
$ virsh -c test:///default snapshot-delete test blah
error: Domain snapshot not found: no domain snapshot with matching name 'blah'
error: Domain snapshot not found: no domain snapshot with matching name 'blah'
Fix things by telling libvirt to discard any thread-local errors at
the same time virsh prints an error message (whether or not the libvirt
error is the same as what is stored in last_error).
Update the virsh-undefine testsuite (partially reverting portions of
commit b620bdee, by removing -q, to more easily pinpoint which commands
are causing which messages), now that there is only one error message
instead of two.

There are couple of things wrong with the current implementation.

allocated in a temporary buffer and are not duplicated this
results in wrong decision made later in the code.
The second problem is that the code does not take into account
subtree mounts. For instance, if there's a fuse.gluster mounted
at /some/path and another FS mounted at /some/path/subdir the

Introduce some basic test cases for virFileIsSharedFS(). More
will be added later. In order to achieve desired result, mocks
for setmntent() and statfs() need to be invented because the
first thing that virFileIsSharedFS() does is calling the latter.
If it finds a FUSE mount it'll call the former.
The mock might look a bit complicated, but in fact it's quite
simple. The test sets LIBVIRT_MTAB env variable to hold the
absolute path to a file containing mount table. Then, statfs()
returns matching FS it finds, and setmntent() is there just to
replace /proc/mounts with the file the test wants to load.
Adding this test also exposed a bug we have - because we assume
the given path points to a file we cut off what we assume is a
file name to obtain directory path and only then we call
statfs(). This is buggy because the passed path could be already
a mount point.
