We allow the postParse callbacks to fail for some reasons (missing
emulator binary) when parsing the configs from /etc/libvirt.
In that case, def->postParseFailed is set to true and the post
parse callbacks are re-executed on domain startup.
However this bool was only set when virDomainDefPostParse was called
with the ALLOW_POST_PARSE_FAIL flag set. If the callback failed
again on domain startup, the bool would be reset and subsequent
startups would not attempt to reexecute the callback.

A problem encountered due to a bug in libpcap was reported to the
caller as:
An error occurred, but the cause is unknown
This was because the error had been logged in the DHCPSnoop
thread. The worker thread handling the API call to start a domain
spins up the DHCPSnoop thread which watches for dhcp packets with
libpcap, then uses virCondSignal() to notify the worker thread (which
has been waiting with virCondWait()). The worker thread knows that
there was an error (because threadStatus != THREAD_STATUS_OK), but the
error info had been stored in thread-specific storage for the other
thread, so the worker thread can only report that there was a failure,
but it doesn't know why.
The solution is to save the error that was logged (with
virErrorPreserveLast() into the object the is used to share info
between the threads, then we can set the error in the worker thread
using virErrorRestore().

GCC 8 became more fussy about detecting switch
fallthroughs. First it doesn't like it if you have
a fallthrough attribute that is not before a case
statement. e.g.
FOO:
BAR:
WIZZ:
ATTRIBUTE_FALLTHROUGH;
Is unacceptable as there's no final case statement,
so while FOO & BAR are falling through, WIZZ is
not falling through. IOW, GCC wants us to write
FOO:
BAR:
ATTRIBUTE_FALLTHROUGH;
WIZZ:
Second, it will report risk of fallthrough even if you
have a case statement for every single enum value, but
only if the switch is nested inside another switch and
the outer case statement has no final break. This is
is arguably valid because despite the fact that we have
cast from "int" to the enum typedef, nothing guarantees
that the variable we're switching on only contains values
that have corresponding switch labels. e.g.
int domstate = 87539319;
switch ((virDomainState)domstate) {
...
}
will not match enum value, but also not raise any kind
of compiler warning. So it is right to complain about
risk of fallthrough if no default: is present.
Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
The controller model is slightly unusual in that the default value is
-1, not 0. As a result the default value is not covered by any of the
existing enum cases. This in turn means that any switch() statements
that think they have covered all cases, will in fact not match the
default value at all. In the qemuDomainDeviceCalculatePCIConnectFlags()
method this has caused a serious mistake where we fallthrough from the
SCSI controller case, to the VirtioSerial controller case, and from
the USB controller case to the IDE controller case.
By adding explicit enum constant starting at -1, we can ensure switches
remember to handle the default case.

Commit 7e62c4cd26 (first appearing in libvirt-3.9.0 as a resolution
to rhbz #1343919) added a "generated" attribute to virMacAddr that was
set whenever a mac address was auto-generated by libvirt. This
knowledge was used in a single place - when trying to match a NetDef
from the Domain to Delete with user-provided XML. Since the XML parser
always auto-generates a MAC address for NetDefs when none is provided,
it was previously impossible to make a search where the MAC address
isn't significant, but the addition of the "generated" attribute made
it possible for the search function to ignore auto-generated MACs.
This implementation had a problem though - it was adding a field to a
"low level" struct - virMacAddr - which is used in other places with
the assumption that it contains exactly a 6 byte MAC address and
nothing else. In particular, virNWFilterSnoopEthHdr uses virMacAddr as
part of the definition of an ethernet packet header, whose layout must
of course match an actual ethernet packet. Adding the extra bools into
virNWFilterSnoopEthHdr caused the nwfilter driver's "IP discovery via
DHCP packet snooping" functionality to mysteriously stop working.
In order to fix that behavior, and prevent potential future similar
odd behavior, this patch moves the "generated" member out of
virMacAddr (so that it is again really is just a MAC address) into
virDomainNetDef, and sets it only when virDomainNetGenerateMAC() is
called from virDomainNetDefParseXML() (which is the only time we care
about it).

We're already checking if IPv4 prefix isn't too long. But we are
not checking if it isn't too short. QEMU supports prefixes longer
than 4 (including). I haven't find anything similar related to
IPv6 in qemu sources.

The array indexes are formatted if the JSON->commandline translator is
translating an array type. It does not at all depend on this function.

Instead of storing separately whether the feature is enabled
or not and what resizing policy should be used, store both of
them in a single place.

When no GIC version is specified, we currently default to GIC v2;
however, that's not a great default, since guests will fail to
start if the hardware only supports GIC v3.
Change the behavior so that a sensible default is chosen instead.
That basically means using the same algorithm whether the user
didn't explicitly enable the GIC feature or they explicitly
enabled it but didn't specify any GIC version.

Unlike most other features, VIR_DOMAIN_FEATURE_CAPABILITIES is
of type virDomainCapabilitiesPolicy instead of virTristateSwitch,
so we need to handle it separately for the error message to make

We want to perform all feature verification in a single spot, but
some of it (eg. GIC) is currently being performed at command line
generation time, and moving it to PostParse() would cause guests
to disappear. Moving verification to Validate() allows us to
side-step the issue.

This reverts commit 038eb472a0.
On reflection adding defaults for arbitrary guest XML device config

Commit 'f0f2a5ec2' neglected to adjust the if condition to split

Just split out the condition and use previous/original message, but

Fortunately the extra stuff virGetHostname does is totally irrelevant to
the needs of the logging code, so we can just inline a call to the
native hostname() syscall directly.

The Win32 symbol export file format can't do wildcards, so none of
the 'xdr_*' symbols are exported from the libvirt DLL. This doesn't
matter generally since the RPC client is built into the DLL and we
don't build libvirtd on Win32. The virnetmessagetest, however, does
require xdr_virNetMessageError to be exported, so just do a hack for
that.
