Andrzej Zaborowski is listed as an "Odd Fixes" maintainer for the
nSeries, Palm and PXA2XX boards, as well as the "Maintained" status
Arm 32-bit TCG backend.
Andrzej's last email to qemu-devel was back in 2017, and the email
before that was all the way back in 2013. We don't really need to
fill his email up with CCs on QEMU patches any more...
Remove Andrzej from the various boards sections (leaving them still
Odd Fixes with me as the backup patch reviewer). Add Richard
Henderson as the maintainer for the Arm TCG backend, since removing
Andrzej would otherwise leave that section with no M: line at all.

The initial value of VLAN Ether Type (VET) register is 0x8100, as per
the manual and real hardware.
While Linux e1000e driver always writes VET register to 0x8100, it is
not always the case for everyone. Drivers relying on the reset value
of VET won't be able to transmit and receive VLAN frames in QEMU.
Unlike e1000 in QEMU, e1000e uses a field 'vet' in "struct E1000Core"
to cache the value of VET register, but the cache only gets updated
when VET register is written. To always get a consistent VET value
no matter VET is written or remains its reset value, drop the 'vet'
field and use 'core->mac[VET]' directly.

Coverity seems to have issues figuring out the properties of g_malloc0
and other non *_n functions. While this was "fixed" by removing the
custom second argument to __coverity_mark_as_afm_allocated__, inline
the code from the array-based allocation functions to avoid future
issues.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
g_malloc/g_malloc0/g_realloc only return NULL if the size is 0; we do not need
to cover that in the model, and so far have expected __coverity_alloc__
to model a non-NULL return value. But that apparently does not work
anymore, so add some extra conditionals that invoke __coverity_panic__
for NULL pointers.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
These models are not needed anymore now that Coverity does not check
anymore that the result is used with "g_free". Coverity understands
GCC attributes and uses them to detect leaks.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Recently, Coverity has started complaining about using g_free() to free
memory areas allocated by GLib functions not included in model.c,
such as g_strfreev. This unfortunately goes against the GLib
documentation, which suggests that g_malloc() should be matched
with g_free() and plain malloc() with free(); since GLib 2.46 however
g_malloc() is hardcoded to always use the system malloc implementation,
and g_free is just "free" plus a tracepoint. Therefore, this
should not cause any problem in practice.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Use void * for consistency with the actual function; provide a model
for MemoryRegionCache functions and for address_space_rw. These
let Coverity understand the bounds of the data that various functions
read and write even at very high levels of inlining (e.g. pci_dma_read).

-readconfig is still recording SMP options in QemuOpts instead of
using machine_opts_dict. This means that SMP options from -readconfig
are ignored.
Just stop using QemuOpts for -smp, making it return false for
is_qemuopts_group. Configuration files will merge the values in
machine_opts_dict using the new function machine_merge_property.
At the same time, fix -mem-prealloc which looked at QemuOpts to find the
number of guest CPUs, which it used as the default number of preallocation
threads.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
It will be used to parse smp-opts config groups from configuration
files. The point to note is that it does not steal a reference
from the caller. This is better because this function will be called
from qemu_config_foreach's callback; qemu_config_foreach does not cede
its reference to the qdict to the callback, and wants to free it. To
balance that extra reference, machine_parse_property_opt now needs
a qobject_unref.

get_supported_hv_cpuid_legacy() when 'cs->kvm_state' is NULL. While
'cs->kvm_state' can indeed be NULL in hv_cpuid_get_host(),
kvm_hyperv_expand_features() makes sure that it only happens when
KVM_CAP_SYS_HYPERV_CPUID is supported and KVM_CAP_SYS_HYPERV_CPUID
implies KVM_CAP_HYPERV_CPUID so get_supported_hv_cpuid_legacy() is

If maintainers are currently pushing to a branch called "staging"

The iotests 197 and 215 are occasionally failing in the gitlab-CI now.
According to the log, the failure is "./common.rc: Killed" which might
be an indication that the process has been killed due to out-of-memory
reasons. Both tests are doing a big read with 2G that likely causes
this issue. It used to work fine in the gitlab-CI in the past, but
either the program is now requiring more free memory, or the the CI
containers have changed, so that the OOM condition now sometimes occurs.
Anyway, these two tests are not really suitable for CI containers if
they are doing things like huge reads (which is likely also the reason
why they haven't been added to the "auto" group in the past), so let's
simply disable them in the gitlab-CI now, too.
