2021-08-02docs/devel: Format literals correctlyPeter Maydell
In rST markup, single backticks `like this` represent "interpreted text", which can be handled as a bunch of different things if tagged with a specific "role": https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#interpreted-text (the most common one for us is "reference to a URL, which gets hyperlinked"). The default "role" if none is specified is "title_reference", intended for references to book or article titles, and it renders into the HTML as <cite>...</cite> (usually comes out as italics). Fix various places in the devel section of the manual which were using single backticks when double backticks (for literal text) were intended.

2021-08-02docs: Move licence/copyright from HTML output to rST commentsPeter Maydell
Our built HTML documentation now has a standard footer which gives the license for QEMU (and its documentation as a whole). In almost all pages, we either don't bother to state the copyright/license for the individual rST sources, or we put it in an rST comment. There are just three pages which render copyright or license information into the user-visible HTML. Quoting a specific (different) license for an individual HTML page within the manual is confusing. Downgrade the license and copyright info to a comment within the rST source, bringing these pages in line with the rest of our documents.

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.

2021-07-30coverity-model: write models fully for non-array allocation functionsPaolo Bonzini
Coverity seems to have issues figuring out the properties of g_malloc0 and other non *_n functions.

2021-07-30coverity-model: constrain g_malloc/g_malloc0/g_realloc as never returning NULLPaolo Bonzini
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>

2021-07-30coverity-model: remove model for more allocation functionsPaolo Bonzini
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>
2021-07-30coverity-model: make g_free a synonym of freePaolo Bonzini
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>
2021-07-30coverity-model: update address_space_read/write modelsPaolo Bonzini
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). Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2021-07-30vl: stop recording -smp in QemuOptsPaolo Bonzini
-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>
2021-07-30vl: introduce machine_merge_propertyPaolo Bonzini
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. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2021-07-29docs: Incorporate information in usb-storage.txt into rST manualPeter Maydell
We already have a section on USB in the rST manual; fold the information in docs/usb-storage.txt into it. We add 'format=raw' to the various -drive options in the code examples, because QEMU will print warnings these days if you omit it.

2021-07-29usbredir: fix free callGerd Hoffmann
data might point into the middle of a larger buffer, there is a separate free_on_destroy pointer passed into bufp_alloc() to handle that. It is only used in the normal workflow though, not when dropping packets due to the queue being full. Fix that.

2021-07-29meson: fix meson 0.58 warning with libvhost-user subprojectMarc-André Lureau
Meson now checks that subprojects do not access files from parent project. While we all agree this is best practice, libvhost-user also want to share a few headers with QEMU, and libvhost-user isn't really a standalone project at this point (although this is making the dependency a bit more explicit).

VMRUN exits with SVM_EXIT_ERR if either: * The event injected has a reserved type. * When the event injected is of type 3 (exception), and the vector that has been specified does not correspond to an exception.

2021-07-29configure: Add -Werror to avx2, avx512 testsRichard Henderson
When using clang, we get ERROR: configure test passed without -Werror but failed with -Werror. This is probably a bug in the configure script. The failing command will be at the bottom of config.log. You can run configure with --disable-werror to bypass this check. What we really want from these two tests is whether the entire code sequence is supported, including pragmas. Adding -Werror makes the test properly fail for clang.

2021-07-29Makefile: ignore long optionsAlexey Neyman
When searching for options like -n in MAKEFLAGS, current code may result in a false positive match when make is invoked with long options like --no-print-directory. This has been observed with certain versions of host make (e.g. 3.82) while building the Qemu package in buildroot. Filter out such long options before searching for one-character options.

2021-07-29i386: assert 'cs->kvm_state' is not nullVitaly Kuznetsov
Coverity reports potential NULL pointer dereference in 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 never really called. Add asserts to strengthen the protection against broken KVM behavior.
