2023-10-04tcg: Split out tcg init functions to tcg/startup.hRichard Henderson
The tcg/tcg.h header is a big bucket, containing stuff related to the translators and the JIT backend. The places that initialize tcg or create new threads do not need all of that, so split out these three functions to a new header.

2023-10-04osdep: set _FORTIFY_SOURCE=2 when optimization is enabledDaniel P. Berrangé
Currently we set _FORTIFY_SOURCE=2 as a compiler argument when the meson 'optimization' setting is non-zero, the compiler is GCC and the target is Linux. While the default QEMU optimization level is 2, user could override this by setting CFLAGS="-O0" or --extra-cflags="-O0" when running configure and this won't be reflected in the meson 'optimization' setting. As a result we try to enable _FORTIFY_SOURCE=2 and then the user gets compile errors as it only works with optimization. Rather than trying to improve detection in meson, it is simpler to just check the __OPTIMIZE__ define from osdep.h. The comment about being incompatible with clang appears to be outdated, as compilation works fine without excluding clang. In the coroutine code we must set _FORTIFY_SOURCE=0 to stop the logic in osdep.h then enabling it. Signed-off-by: Daniel P.

2023-10-04migration/vmstate: Introduce vmstate_save_state_with_errTejus GK
Currently, a few code paths exist in the function vmstate_save_state_v, which ultimately leads to a migration failure. However, an update in the current MigrationState for the error description is never done. vmstate.c somehow doesn't seem to allow the use of migrate_set_error due to some dependencies for unit tests. Hence, this patch introduces a new function vmstate_save_state_with_err, which will eventually propagate the error message to savevm.c where a migrate_set_error call can be eventually done.

2023-10-04virtio: don't zero out memory region cache for indirect descriptorsIlya Maximets
Lots of virtio functions that are on a hot path in data transmission are initializing indirect descriptor cache at the point of stack allocation. It's a 112 byte structure that is getting zeroed out on each call adding unnecessary overhead. It's going to be correctly initialized later via special init function. The only reason to actually initialize right away is the ability to safely destruct it. Replacing a designated initializer with a function to only initialize what is necessary. Removal of the unnecessary stack initializations improves throughput of virtio-net devices in terms of 64B packets per second by 6-14 % depending on the case. Tested with a proposed af-xdp network backend and a dpdk testpmd application in the guest, but should be beneficial for other virtio devices as well.

2023-09-29qobject atomics osdep: Make a few macros more hygienicMarkus Armbruster
Variables declared in macros can shadow other variables. Much of the time, this is harmless, e.g.: #define _FDT(exp) \ do { \ int ret = (exp); \ if (ret < 0) { \ error_report("error creating device tree: %s: %s", \ #exp, fdt_strerror(ret)); \ exit(1); \ } \ } while (0) Harmless shadowing in h_client_architecture_support(): target_ulong ret; [...] ret = do_client_architecture_support(cpu, spapr, vec, fdt_bufsize); if (ret == H_SUCCESS) { _FDT((fdt_pack(spapr->fdt_blob))); [...] } return ret; However, we can get in trouble when the shadowed variable is used in a macro argument: #define QOBJECT(obj) ({ \ typeof(obj) o = (obj); \ o ? container_of(&(o)->base, QObject, base) : NULL; \ }) QOBJECT(o) expands into ({ ---> typeof(o) o = (o); o ? container_of(&(o)->base, QObject, base) : NULL; }) Unintended variable name capture at --->. We'd be saved by -Winit-self. But I could certainly construct more elaborate death traps that don't trigger it. To reduce the risk of trapping ourselves, we use variable names in macros that no sane person would use elsewhere. Here's our actual definition of QOBJECT(): #define QOBJECT(obj) ({ \ typeof(obj) _obj = (obj); \ _obj ? container_of(&(_obj)->base, QObject, base) : NULL; \ }) Works well enough until we nest macro calls. For instance, with #define qobject_ref(obj) ({ \ typeof(obj) _obj = (obj); \ qobject_ref_impl(QOBJECT(_obj)); \ _obj; \ }) the expression qobject_ref(obj) expands into ({ typeof(obj) _obj = (obj); qobject_ref_impl( ({ ---> typeof(_obj) _obj = (_obj); _obj ? container_of(&(_obj)->base, QObject, base) : NULL; })); _obj; }) Unintended variable name capture at --->. The only reliable way to prevent unintended variable name capture is -Wshadow. One blocker for enabling it is shadowing hiding in function-like macros like qdict_put(dict, "name", qobject_ref(...)) qdict_put() wraps its last argument in QOBJECT(), and the last argument here contains another QOBJECT(). Use dark preprocessor sorcery to make the macros that give us this problem use different variable names on every call.
