Subject: [PATCH] security: Don't increase XATTRs refcounter on failure
|
||||
|
||||
If user has two domains, each have the same disk (configured for
|
||||
RW) but each runs with different seclabel then we deny start of
|
||||
the second domain because in order to do that we would need to
|
||||
relabel the disk but that would cut the first domain off. Even if
|
||||
we did not do that, qemu would fail to start because it would be
|
||||
unable to lock the disk image for the second time. So far, this
|
||||
behaviour is expected. But what is not expected is that we
|
||||
increase the refcounter in XATTRs and leave it like that.
|
||||
|
||||
What happens is that when the second domain starts,
|
||||
virSecuritySetRememberedLabel() is called, and since there are
|
||||
XATTRs from the first domain it increments the refcounter and
|
||||
returns it (refcounter == 2 at this point). Then callers
|
||||
(virSecurityDACSetOwnership() and
|
||||
virSecuritySELinuxSetFileconHelper()) realize that refcounter is
|
||||
greater than 1 and desired seclabel doesn't match the one the
|
||||
disk image already has and an error is produced. But the
|
||||
refcounter is never decremented.

Subject: [PATCH] security_util: Remove stale XATTRs
|
||||
|
||||
It may happen that we leave some XATTRs behind. For instance, on
|
||||
a sudden power loss, the host just shuts down without calling
|
||||
restore on domain paths. This creates a problem, because when the
|
||||
host starts up again, the XATTRs are there but they don't reflect
|
||||
the true state and this may result in libvirt denying start of a
|
||||
domain.
|
||||
|
||||
To solve this, save a unique timestamp (host boot time) among
|
||||
with our XATTRs.

Subject: [PATCH] virSecuritySELinuxSetFileconImpl: Drop @optional argument
|
||||
|
||||
The only thing that the @optional argument does is that it makes
|
||||
the function return 1 instead of 0 if setting SELinux context
|
||||
failed in a non-critical fashion. Drop the argument then and
|
||||
return 1 in that case. This enables caller to learn if SELinux
|
||||
context was set or not.

Subject: [PATCH] security_selinux: Play nicely with network FS that only
|
||||
emulates SELinux
|
||||
|
||||
There are some network file systems that do support XATTRs (e.g.
|
||||
gluster via FUSE). And they appear to support SELinux too.
|
||||
However, not really. Problem is, that it is impossible to change
|
||||
SELinux label of a file stored there, and yet we claim success
|
||||
(rightfully - hypervisor succeeds in opening the file). But this
|
||||
creates a problem for us - from XATTR bookkeeping POV, we haven't
|
||||
changed the label and thus if we remembered any label, we must
|
||||
roll back and remove it.
|

Subject: [PATCH] qemu_blockjob: Print image path on failed security metadata

|
||||
|
||||
When a block job is completed, the security image metadata are
|

moved to the new image. If this fails an warning is printed, but
|
||||
the message contains only domain name and lacks image paths. Put
|
||||
them both into the warning message.

Subject: [PATCH] network: fix crash during cleanup from failure to allocate
|
||||
port
|
||||
|
||||
During networkPortCreateXML, if networkAllocatePort() failed,
|
||||
networkReleasePort() would be called, which would (in the case of
|
||||
network pools of macvtap passthrough devices) attempt to find the
|
||||
allocated device by comparing port->plug.direct.linkdev to each device
|
||||
in the pool. Since port->plug.direct.linkdev was still NULL, the
|
||||
attempted strcmp would result in a SEGV.
|
||||
|
||||
Calling networkReleasePort() during error cleanup is something that
|
||||
should only be done if networkAllocatePort() has already succeeded. It
|
||||
turns out there is one other possible error exit from
|
||||
networkPortCreateXML() that happens after networkAllocatePort() has
|
||||
succeeded, so the code to call networkReleasePort() was just moved
|
||||
down to there.

virErrorPreserveLast()/virErrorRestore() (added in commit 8333e7455

back in 2017), do a better better job of saving and restoring the last

libvirt error than virSaveLastError()/virErrorRestore() (they're

simpler, and they also save/restore the system errno).

Subject: [PATCH] access: fix incorrect addition to virAccessPermNetwork
|
||||
|
||||
Commit e69444e17 (first appeared in libvirt-5.5.0) added the new value
|
||||
"VIR_ACCESS_PERM_NETWORK_SEARCH_PORTS" to the virAccessPerNetwork
|
||||
enum, and also the string "search_ports" to the VIR_ENUM_IMPL() macro
|
||||
for that enum. Unfortunately, the enum value was added in the middle
|
||||
of the list, while the string was added to the end of the
|
||||
VIR_ENUM_IMPL().
|
||||
|
||||
This patch corrects that error by moving the new value to the end of
|
||||
the enum definition, so that the order matches that of the string
|
||||
list.

Subject: [PATCH] util: allow tap-based guest interfaces to have MAC address
|
||||
prefix 0xFE
|
||||
|
||||
Back in July 2010, commit 6ea90b84 (meant to resolve
|
||||
https://bugzilla.redhat.com/571991 ) added code to set the MAC address
|
||||
of any tap device to the associated guest interface's MAC, but with
|
||||
the first byte replaced with 0xFE. This was done in order to assure
|
||||
that
|
||||
|
||||
1) the tap MAC and guest interface MAC were different (otherwise L2
|
||||
forwarding through the tap would not work, and the kernel would
|
||||
repeatedly issue a warning stating as much).
|
||||
|
||||
2) any bridge device that had one of these taps attached would *not*
|
||||
take on the MAC of the tap (leading to network instability as
|
||||
guests started and stopped)
|
||||
|
||||
A couple years later, https://bugzilla.redhat.com/798467 was filed,
|
||||
complaining that a user could configure a tap-based guest interface to
|
||||
have a MAC address that itself had a first byte of 0xFE, silently
|
||||
(other than the kernel warning messages) resulting in a non-working
|
||||
configuration. This was fixed by commit 5d571045, which logged an
|
||||
error and failed the guest start / interface attach if the MAC's first
|
||||
byte was 0xFE.
|
||||
|
||||
Although this restriction only reduces the potential pool of MAC
|
||||
addresses from 2^46 (last two bits of byte 1 must be set to 10) by
|
||||
2^32 (still 4 orders of magnitude larger than the entire IPv4 address
|
||||
space), it also means that management software that autogenerates MAC
|
||||
addresses must have special code to avoid an 0xFE prefix. Now after 7
|
||||
years, someone has noticed this restriction and requested that we
|
||||
remove it.
|
||||
|
||||
So instead of failing when 0xFE is found as the first byte, this patch
|
||||
removes the restriction by just replacing the first byte in the tap
|
||||
device MAC with 0xFA if the first byte in the guest interface is
|
||||
0xFE. 0xFA is the next-highest value that still has 10 as the lowest
|
||||
two bits, and still
|
||||
|
||||
2) meets the requirement of "tap MAC must be different from guest
|
||||
interface MAC", and
|
||||
|
||||
3) is high enough that there should never be an issue of the attached
|
||||
bridge device taking on the MAC of the tap.
|
||||
|
||||
The result is that *any* MAC can be chosen by management software
|
||||
(although it would still not work correctly if a multicast MAC (lowest
|
||||
bit of first byte set to 1) was chosen), but that's a different
|
||||
issue).

When using systemd socket activation the --listen arg has no
|
||||
effect. This is confusing to users upgrading from previous versions of
|
||||
libvirt as their config is silently ignored. Turn use of --listen into a
|
||||
fatal error when sockets are passed from systemd.
|
||||
|
||||
This helps the admin discover the change in behaviour and thus decide
|
||||
whether to stick with socket activation or revert to previous behaviour.

+The B<libvirtd> daemon is capable of starting in two modes.

|

+In socket activation mode, it will rely on systemd to create and listen

+on the UNIX, and optionally TCP/IP, sockets and pass them as pre-opened

+file descriptors. In this mode, it is not permitted to pass the B<--listen>

+B</etc/libvirt/libvirtd.conf> will no longer have any effect. To enable

present

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit

|
||||
Currently during RPM upgrade we restart libvirtd and unconditionally
|
||||
enable use of systemd socket activation for the UNIX sockets.
|
||||
|
||||
If the user had previously given the --listen arg to libvirtd though,
|
||||
this will no longer be honoured if socket activation is used.
|
||||
|
||||
We could start libvirtd-tcp.socket or libvirtd-tls.socket for this,
|
||||
but mgmt tools like puppet/ansible might not be expecting this.
|
||||
So for now we silently disable socket activation if we see --listen
|
||||
was previously set on the host.

Subject: [PATCH] vircgroupv2: fix setting cpu.max period
|
||||
|
||||
When we set cpu.max period we need to parse the cpu.max file first as
|
||||
it contains both quota and period values separated by space. When only
|
||||
a single number is written to that file it will set quota. However,
|
||||
in order to change period we need to write both values.
|
||||
|
||||
The code was prepared for that but mistakenly used new line to end the
|
||||
string with the first value.

Subject: [PATCH] vircgroupv2: Fix VM startup when legacy cgroups are defined
|
||||
|
||||
On Fedora 31, starting a 'mock' build alters /proc/$pid/cgroup,
|
||||
probably due to usage of systemd-nspawn.
|
||||
|
||||
Before:
|
||||
$ cat /proc/self/cgroup
|
||||
0::/user.slice/user-1000.slice/...
|
||||
|
||||
After:
|
||||
$ cat /proc/self/cgroup
|
||||
1:name=systemd:/
|
||||
0::/user.slice/user-1000.slice/...
|
||||
|
||||
The cgroupv2 code mishandles that first line in the second case, which
|
||||
causes VM startup to fail with: Unable to read from
|
||||
'/sys/fs/cgroup/machine/cgroup.controllers': No such file or directory
|
||||
|
||||
The kernel docs[1] say that the cgroupv2 path will always start with
|
||||
'0::', which in the code here controllers="". Only set the v2 placement
|
||||
path when we see that cgroup file entry.

Subject: [PATCH] driver: Introduce virDriverShouldAutostart()

|

Some of objects we manage can be autostarted on libvirtd startup
|
||||
(e.g. domains, network, storage pools). The idea was that when
|
||||
the host is started up these objects are started too without need
|
||||
of user intervention. However, with the latest daemon split and
|
||||
switch to socket activated, short lived daemons (we put --timeout
|
||||
120 onto each daemon's command line) this doesn't do what we want
|
||||
it to. The problem is not new though, we already had the session
|
||||
daemon come and go and we circumvented this problem by
|
||||
documenting it (see v4.10.0-92-g61b4e8aaf1). But now that we meet
|
||||
the same problem at all fronts it's time to deal with it.
|
||||
|
||||
The solution implemented in this commit is to have a file (one
|
||||
per each driver) that:
|
||||
|
||||
1) if doesn't exist, is created and autostart is allowed for
|
||||
given driver,
|
||||
|
||||
2) if it does exist, then autostart is suppressed for given
|
||||
driver.
|
||||
|
||||
All the files live in a location that doesn't survive host
|
||||
reboots (/var/run/ for instance) and thus the file is
|
||||
automatically not there on fresh host boot.

With the recent work in daemon split and socket activation
|

daemons can come and go. They can and will be started many times
|

during a session which results in objects being autostarted
|
||||
multiple times. This is not optimal. Use

virDriverShouldAutostart() to determine if autostart should be

done or not.

Subject: [PATCH] util: allow sending mac addr to virNetNewLink without ifindex
|
||||
|
||||
Although until now, any use of the extra_args argument (a pointer to a
|
||||
struct containing extra attributes to add the the RTM_NEWLINK message)
|
||||
would always have the ifindex and mac set, so the code could assume it
|
||||
was safe to add both to the message if extra_args != NULL. There is
|
||||
now a use for setting a MAC address in the RTM_NEWLINK without setting
|
||||
the ifindex, so we should check each of these separately.

for the bridges created for libvirt virtual networks (commit
|
||||
5754dbd56d, in libvirt v0.8.8) most distro stable releases didn't
|
||||
support explicitly setting the MAC address of a bridge; the bridge
|
||||
just always assumed the lowest numbered MAC of all attached
|
||||
interfaces. Because of this, we stabilized the bridge MAC address by
|
||||
creating a "dummy" tap interface with a MAC address guaranteed to be
|
||||
lower than any of the guest tap devices' MACs (which all started with
|
||||
0xFE, so it's not difficult to do) and attached it to the bridge -
|
||||
this was the inception of the "virbr0-nic" device that has confused so
|
||||
many people over the years.
|
||||
|
||||
Even though the linux kernel had recently gained support for
|
||||
explicitly setting a bridge MAC, we deemed it unnecessary to set the
|
||||
MAC that way, because the other (indirect) method worked everywhere.
|
||||
|
||||
But recently there have been reports that the bridge MAC address was
|
||||
not following the setting in the network config, and mismatched the
|
||||
MAC of the dummy tap device (which was still correct). It turns out
|
||||
that this is due to a change in systemd-242 that persists whatever MAC
|
||||
address is set for a bridge when it's initially started. According to
|
||||
the systemd NEWS file entry for version 242
|
||||
(https://github.com/systemd/systemd/blob/master/NEWS):
|
||||
|
||||
"if a bridge interface is created without any slaves, and gains
|
||||
a slave later, then now the bridge does not inherit slave's MAC."
|
||||
|
||||
This change was the result of:
|
||||
|
||||
https://github.com/systemd/systemd/issues/3374
|
||||
|
||||
(apparently if there is no MAC saved for a bridge by the name of a
|
||||
bridge being created, the random MAC generated during creation is
|
||||
saved, and then that same MAC is used to explicitly set the MAC each
|
||||
time it is created). Once a bridge has an explicitly set MAC, the "use
|
||||
the lowest numbered MAC of attached devices" rule is ignored, so our
|
||||
dummy tap device is like the goggles - it does nothing! (well, almost).
|
||||
|
||||
We could whine about changes in default behavior, etc. etc., but
|
||||
because the change was in response to actual user problems, that seems
|
||||
likely a fruitless task. Fortunately, time has marched on, and even
|
||||
distro releases that are old enough that they are no longer supported
|
||||
by upstream libvirt (e.g. RHEL6) have support for explicitly setting a
|
||||
bridge device MAC address, either during creation or with a separate
|
||||
ioctl after creation, so we can now do that.
|
||||
|
||||
To enable explicitly setting the mac during bridge creation, we add a
|
||||
mac arg to virNetDevBridgeCreate(). In the case of platforms where
|
||||
the bridge is created with a netlink RTM_NEWLINK message, we just add
|
||||
that mac to the message. For platforms that still use an ioctl (either
|
||||
SIOCBRADDBR or SIOCIFCREATE2), we make a separate call to
|
||||
virNetDevSetMAC() after creating the bridge.
|
||||
|
||||
(NB: I was unable to test the calling of virNetDevSetMAC() from the
|
||||
SIOCIFCREATE2 (BSD) version of virNetDevBridgeCreate(); even though I
|
||||
managed to get a FreeBSD system setup and libvirt built there, when I
|
||||
tried to start the default network the SIOCIFCREATE2 ioctl itself
|
||||
failed, so it never even got to the virNetDevSetMAC(). That leaves the
|
||||
FreeBSD implementation untested.)
|
||||
|
||||
This makes the dummy tap pointless for purposes of setting the MAC
|
||||
address, but it is still useful for IPv6 DAD initialization (which
|
||||
apparently requires at least one interface to be attached to the
|
||||
bridge and online), as well as for setting an initial MTU for the
|
||||
bridge, so it hasn't been removed.
|
||||
|
||||
(NB: we can safely *always* call virNetDevBridgeCreate() with
|
||||
&def->mac from the network driver because, in spite of the existence
|
||||
of a "mac_specified" bool in the config suggesting that it may not
|
||||
always be present, in reality a mac address will always be added to
|
||||
any network that doesn't have one - this is guaranteed in all cases by
|
||||
commit a47ae7c004)

Subject: [PATCH] virhostuptime: Add linux stub for musl
|
||||
|
||||
When we want to know the boot timestamp of the host, we can call
|
||||
virHostGetBootTime(). Under the hood, it uses getutxid() which is
|
||||
defined by POSIX and properly check for in configure. However,
|
||||
musl took a path where it declares the function but instead of
|
||||
providing any useful implementation it returns NULL meaning "no
|
||||
record found". If that's the case, use our second best option -
|
||||
/proc/uptime and a bit of maths.

Subject: [PATCH] remote_daemon: Initialize host boot time global variable
|
||||
|
||||
This is not strictly needed, but it makes sure we initialize the
|
||||
@bootTime global variable. Thing is, in order to validate XATTRs
|
||||
and prune those set in some previous runs of the host, a
|
||||
timestamp is recorded in XATTRs. The host boot time was unique
|
||||
enough so it was chosen as the timestamp value. And to avoid
|
||||
querying and parsing /proc/uptime every time, the query function
|
||||
does that only once and stores the boot time in a global
|
||||
variable. However, the only time the query function is called is
|
||||
in a child process that does lock files and changes seclabels. So
|
||||
effectively, we are doing exactly what we wanted to prevent from
|
||||
happening.
|
||||
|
||||
The fix is simple, call the virHostBootTimeInit() function which
|
||||
sets the global variable.

networkSetupPrivateChains() is currently called only once per run of

libvirtd, so it can assume that errInitV4 and errInitV6 are empty/null
|

when it is called. In preparation for potentially calling this

function multiple times during one run, this patch moves the reset of

errInitV[46] to the top of the function, to assure no memory is

Subject: [PATCH] network: force re-creation of iptables private chains on
|
||||
firewalld restart
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
When firewalld is stopped, it removes *all* iptables rules and chains,
|
||||
including those added by libvirt. Since restarting firewalld means
|
||||
stopping and then starting it, any time it is restarted, libvirt needs
|
||||
to recreate all the private iptables chains it uses, along with all
|
||||
the rules it adds.
|
||||
|
||||
We already have code in place to call networkReloadFirewallRules() any
|
||||
time we're notified of a firewalld start, and
|
||||
networkReloadFirewallRules() will call
|
||||
networkPreReloadFirewallRules(), which calls
|
||||
networkSetupPrivateChains(); unfortunately that last call is called
|
||||
using virOnce(), meaning that it will only be called the first time
|
||||
through networkPreReloadFirewallRules() after libvirtd starts - so of
|
||||
course when firewalld is later restarted, the call to
|
||||
networkSetupPrivateChains() is skipped.
|
||||
|
||||
The neat and tidy way to fix this would be if there was a standard way
|
||||
to reset a pthread_once_t object so that the next time virOnce was
|
||||
called, it would think the function hadn't been called, and call it
|
||||
again. Unfortunately, there isn't any official way of doing that (we
|
||||
*could* just fill it with 0 and hope for the best, but that doesn't
|
||||
seem very safe.
|
||||
|
||||
So instead, this patch just adds a static variable called
|
||||
chainInitDone, which is set to true after networkSetupPrivateChains()
|
||||
is called for the first time, and then during calls to
|
||||
networkPreReloadFirewallRules(), if chainInitDone is set, we call
|
||||
networkSetupPrivateChains() directly instead of via virOnce().
|
||||
|
||||
It may seem unsafe to directly call a function that is meant to be
|
||||
called only once, but I think in this case we're safe - there's
|
||||
nothing in the function that is inherently "once only" - it doesn't
|
||||
initialize anything that can't safely be re-initialized (as long as
|
||||
two threads don't try to do it at the same time), and it only happens
|
||||
when responding to a dbus message that firewalld has been started (and
|
||||
I don't think it's possible for us to be processing two of those at
|
||||
once), and even then only if the initial call to the function has
|
||||
already been completed (so we're safe if we receive a firewalld
|
||||
restart call at a time when we haven't yet called it, or even if
|
||||
another thread is already in the process of executing it. The only
|
||||
problematic bit I can think of is if another thread is in the process
|
||||
of adding an iptable rule at the time we're executing this function,
|
||||
but 1) none of those threads will be trying to add chains, and 2) if
|
||||
there was a concurrency problem with other threads adding iptables
|
||||
rules while firewalld was being restarted, it would still be a problem
|
||||
even without this change.
|
||||
|
||||
This is yet another patch that fixes an occurrence of this error:
|
||||
|
||||
COMMAND_FAILED: '/usr/sbin/iptables -w10 -w --table filter --insert LIBVIRT_INP --in-interface virbr0 --protocol tcp --destination-port 67 --jump ACCEPT' failed: iptables: No chain/target/match by that name.

Subject: [PATCH] systemd: start libvirtd after firewalld/iptables services
|
||||
|
||||
When a system has enabled the iptables/ip6tables services rather than
|
||||
firewalld, there is no explicit ordering of the start of those
|
||||
services vs. libvirtd. This creates a problem when libvirtd.service is
|
||||
started before ip[6]tables, as the latter, when it finally is started,
|
||||
will remove all of the iptables rules that had previously been added
|
||||
by libvirt, including the custom chains where libvirt's rules are
|
||||
kept. This results in an error message similar to the following when a
|
||||
user subsequently tries to start a new libvirt network:
|
||||
|
||||
"Error while activating network: Call to virNetworkCreate failed:
|
||||
internal error: Failed to apply firewall rules
|
||||
/usr/sbin/ip6tables -w --table filter --insert LIBVIRT_FWO \
|
||||
--in-interface virbr2 --jump REJECT:
|
||||
ip6tables: No chain/target/match by that name."
|
||||
|
||||
(Prior to logging this error, it also would have caused failure to
|
||||
forward (or block) traffic in some cases, e.g. for guests on a NATed
|
||||
network, since libvirt's rules to forward/block had all been deleted
|
||||
and libvirt didn't know about it, so it couldn't fix the problem)
|
||||
|
||||
When this happens, the problem can be remedied by simply restarting
|
||||
libvirtd.service (which has the side-effect of reloading all
|
||||
libvirt-generated firewall rules)
|
||||
|
||||
Instead, we can just explicitly stating in the libvirtd.service file
|
||||
that libvirtd.service should start after ip6tables.service and
|
||||
ip6tables.service, eliminating the race condition that leads to the
|
||||
error.
|
||||
|
||||
There is also nothing (that I can see) in the systemd .service files
|
||||
to guarantee that firewalld.service will be started (if enabled) prior
|
||||
to libvirtd.service. The same error scenario given above would occur
|
||||
if libvirtd.service started before firewalld.service. Even before
|
||||
that, though libvirtd would have detected that firewalld.service was
|
||||
disabled, and then turn off all firewalld support. So, for example,
|
||||
firewalld's libvirt zone wouldn't be used, and most likely traffic
|
||||
from guests would therefore be blocked (all with no external
|
||||
indication of the source of the problem other than a debug-level log
|
||||
when libvirtd was started saying that firewalld wasn't in use); also
|
||||
libvirtd wouldn't notice when firewalld reloaded its rules (which also
|
||||
simultaneously deletes all of libvirt's rules).
|
||||
|
||||
I'm not aware of any reports that have been traced back to
|
||||
libvirtd.service starting before firewalld.service, but have seen that
|
||||
error reported multiple times, and also don't see an existing
|
||||
dependency that would guarantee firewalld.service starts before
|
||||
libvirtd.service, so it's possible it's been happening and we just
|
||||
haven't gotten to the bottom of it.
|
||||
|
||||
This patch adds an After= line to the libvirtd.service file for each
|
||||
of iptables.service, ip6tables.service, and firewalld.servicee, which
|
||||
should guarantee that libvirtd.service isn't started until systemd has
|
||||
started whichever of the others is enabled.
|
||||
|
||||
This race was diagnosed, and patch proposed, by Jason Montleon in
|
||||
https://bugzilla.redhat.com/1723698 . At the time (April 2019) danpb
|
||||
agreed with him that this change to libvirtd.service was a reasonable
|
||||
thing to do, but I guess everyone thought someone else was going to
|
||||
post a patch, so in the end nobody did.

Subject: [PATCH] qemu: don't hold both jobs for suspend
|
||||
|
||||
We have to assume that the guest agent may be malicious so we don't want
|
||||
to allow any agent queries to block any other libvirt API. By holding a
|
||||
monitor job while we're querying the agent, we open ourselves up to a
|
||||
DoS.
|
||||
|
||||
So split the function up a bit to only hold the monitor job while
|
||||
querying qemu for whether the domain supports suspend. Then acquire only
|
||||
an agent job while issuing the agent suspend command.

Subject: [PATCH] qemu: Fix USB by product with security enabled
|

|

We need to call PrepareHostdevs to determine the USB device path before
|
||||
any security calls. PrepareHostUSBDevices was also incorrectly skipping
|
||||
all USB devices.
