Subject: [PATCH] systemd: directly notify systemd instead of using sd_notify
|
||||
|
||||
The sd_notify method is used to tell systemd when libvirtd
|
||||
has finished starting up. All it does is send a datagram
|
||||
containing the string parameter to systemd on a UNIX socket
|
||||
named in the NOTIFY_SOCKET environment variable. Rather than
|
||||
pulling in the systemd libraries for this, just code the
|
||||
notification directly in libvirt as this is a stable ABI
|
||||
from systemd's POV which explicitly allows independant
|
||||
implementations:
|
||||
|
||||
See "Reimplementable Independently" column in the
|
||||
"$NOTIFY_SOCKET Daemon Notifications" row:

Subject: [PATCH] virDomainDiskTranslateSourcePool: Check for disk type
|
||||
correctly
|
||||
|
||||
When rewriting the virDomainDiskTranslateSourcePool() function in
|
||||
v6.1.0-rc1~184 a typo was introduced. Previously, we allowed
|
||||
startup policy only for those volumes which translated to
|
||||
VIR_STORAGE_TYPE_FILE. But starting with the referenced commit,
|
||||
the value we checked for was changed to VIR_STORAGE_VOL_FILE
|
||||
which comes from a different enum and has a different value too.
|
||||
This is wrong, because virStorageSourceGetActualType() returns a
|
||||
value from the original enum.

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
|

leaked.

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.

Commit 54a401af478 split out DriverConfigInit from DriverConfigNew, but

then called it a bit late from libxlStateInitialize. The cfg is used in

libxlDriverConfigLoadFile and when uninitialized results in a crash.

Calling DriverConfigInit immediately after DriverConfigNew fixes the
