2024-04-01fpu/softfloat: Remove mention of TILE-Gx targetPhilippe Mathieu-Daudé
TILE-Gx has been removed during the v6.0 release (see commit 2cc1a90166 "Remove deprecated target tilegx"), no need to mention it in the list of "supported targets".

2024-04-01usb-audio: Fix invalid values in AudioControl descriptorsJoonas Kankaala
This fixes the invalid bInterfaceProtocol value 0x04 in the USB audio AudioControl descriptors. It should be zero. While Linux and Windows forgive this error, macOS 14 Sonoma does not. The usb-audio device does not appear in macOS sound settings even though the device is recognized and shows up in USB system information. According to the USB audio class specs 1.0-4.0, valid values are 0x00, 0x20, 0x30 and 0x40. (Note also that Linux prints the warning "unknown interface protocol 0x4, assuming v1", but then proceeds as if the value was zero.) This also fixes the invalid wTotalLength value in the multi-channel setup AudioControl interface header descriptor (used when multi=on and out.mixing-engine off). The combined length of all the descriptors there add up to 0x37, not 0x38. In Linux, "lsusb -D ..." displays incomplete descriptor information when this length is incorrect.

There are several places where postcopy_start() fails without setting errp. This can cause a null pointer de-reference, as in case of error, the caller of postcopy_start() copies/prints the error set in errp. Fix it by setting errp in all of postcopy_start() error paths.

2024-03-31migration: Set migration error in migration_completion()Avihai Horon
After commit 9425ef3f990a ("migration: Use migrate_has_error() in close_return_path_on_source()"), close_return_path_on_source() assumes that migration error is set if an error occurs during migration. This may not be true if migration errors in migration_completion(). For example, if qemu_savevm_state_complete_precopy() errors, migration error will not be set. This in turn, will cause a migration hang bug, similar to the bug that was fixed by commit 22b04245f0d5 ("migration: Join the return path thread before releasing to_dst_file"), as shutdown() will not be issued for the return-path channel. Fix it by ensuring migration error is set in case of error in migration_completion().

2024-03-30target/ppc: Do not clear MSR[ME] on MCE interrupts to supervisorNicholas Piggin
Hardware clears the MSR[ME] bit when delivering a machine check interrupt, so that is what QEMU does. The spapr environment runs in supervisor mode though, and receives machine check interrupts after they are processed by the hypervisor, and MSR[ME] must always be enabled in supervisor mode (otherwise it could checkstop the system). So MSR[ME] must not be cleared when delivering machine checks to the supervisor. The fix to prevent supervisor mode from modifying MSR[ME] also prevented it from re-enabling the incorrectly cleared MSR[ME] bit when returning from handling the interrupt. Before that fix, the problem was not very noticable with well-behaved code. So the Fixes tag is not strictly correct, but practically they go together. Found by kvm-unit-tests machine check tests (not yet upstream).

2024-03-30target/ppc: Fix GDB register indexing on secondary CPUsBenjamin Gray
The GDB server protocol assigns an arbitrary numbering of the SPRs. We track this correspondence on each SPR with gdb_id, using it to resolve any SPR requests GDB makes. Early on we generate an XML representation of the SPRs to give GDB, including this numbering. However the XML is cached globally, and we skip setting the SPR gdb_id values on subsequent threads if we detect it is cached. This causes QEMU to fail to resolve SPR requests against secondary CPUs because it cannot find the matching gdb_id value on that thread's SPRs. This is a minimal fix to first assign the gdb_id values, then return early if the XML is cached. Otherwise we generate the XML using the now already initialised gdb_id values.

The 32-bit PA-7300LC (PCX-L2) CPU and the 64-bit PA8700 (PCX-W2) CPU use different diag instructions to save or restore the CPU registers to/from the shadow registers. Implement those per-CPU architecture diag instructions to fix those parts of the HP ODE testcases (L2DIAG and WDIAG, section 1) which test the shadow registers.

2024-03-29Revert "tap: setting error appropriately when calling net_init_tap_one()"Akihiko Odaki
This reverts commit 46d4d36d0bf2b24b205f2f604f0905db80264eef. The reverted commit changed to emit warnings instead of errors when vhost is requested but vhost initialization fails if vhostforce option is not set. However, vhostforce is not meant to ignore vhost errors. It was once introduced as an option to commit 5430a28fe4 ("vhost: force vhost off for non-MSI guests") to force enabling vhost for non-MSI guests, which will have worse performance with vhost. The option was deprecated with commit 1e7398a140 ("vhost: enable vhost without without MSI-X") and changed to behave identical with the vhost option for compatibility. Worse, commit bf769f742c ("virtio: del net client if net_init_tap_one failed") changed to delete the client when vhost fails even when the failure only results in a warning. The leads to an assertion failure for the -netdev command line option. The reverted commit was intended to avoid that the vhost initialization failure won't result in a corrupted netdev. This problem should have been fixed by deleting netdev when the initialization fails instead of ignoring the failure with an arbitrary option. Fortunately, commit bf769f742c ("virtio: del net client if net_init_tap_one failed"), mentioned earlier, implements this behavior. Restore the correct semantics and fix the assertion failure for the -netdev command line option by reverting the problematic commit.

2024-03-29hw/net/net_tx_pkt: Fix virtio header without checksum offloadingAkihiko Odaki
It is incorrect to have the VIRTIO_NET_HDR_F_NEEDS_CSUM set when checksum offloading is disabled so clear the bit. TCP/UDP checksum is usually offloaded when the peer requires virtio headers because they can instruct the peer to compute checksum. However, igb disables TX checksum offloading when a VF is enabled whether the peer requires virtio headers because a transmitted packet can be routed to it and it expects the packet has a proper checksum. Therefore, it is necessary to have a correct virtio header even when checksum offloading is disabled. A real TCP/UDP checksum will be computed and saved in the buffer when checksum offloading is disabled. The virtio specification requires to set the packet checksum stored in the buffer to the TCP/UDP pseudo header when the VIRTIO_NET_HDR_F_NEEDS_CSUM bit is set so the bit must be cleared in that case.

2024-03-28qtest/virtio-9p-test.c: remove g_test_slow() gateDaniel Henrique Barboza
Commit 558f5c42ef gated the local tests with g_test_slow() to skip them in 'make check'. The reported issue back then was this following CI problem: https://lists.nongnu.org/archive/html/qemu-devel/2020-11/msg05510.html This problem ended up being fixed after it was detected with the recently added risc-v machine nodes [1]. virtio-9p-test.c is now creating and removing temporary dirs for each test run, instead of creating a single dir for the entire qos-test scope. We're now able to run these tests with 'make check' in the CI, so let's go ahead and re-enable them. This reverts commit 558f5c42efded3e0d0b20a90bce2a9a14580d824.

2024-03-28qtest/virtio-9p-test.c: create/remove temp dirs after each testDaniel Henrique Barboza
The local 9p driver in virtio-9p-test.c its temporary dir right at the start of qos-test (via virtio_9p_create_local_test_dir()) and only deletes it after qos-test is finished (via virtio_9p_remove_local_test_dir()). This means that any qos-test machine that ends up running virtio-9p-test local tests more than once will end up re-using the same temp dir. This is what's happening in [1] after we introduced the riscv machine nodes: if we enable slow tests with the '-m slow' flag using qemu-system-riscv64, this is what happens: - a temp dir is created; - virtio-9p-device tests will run virtio-9p-test successfully; - virtio-9p-pci tests will run virtio-9p-test, and fail right at the first slow test at fs_create_dir() because the "01" file was already created by fs_create_dir() test when running with the virtio-9p-device. The root cause is that we're creating a single temporary dir, via the construct/destruct callbacks, and this temp dir is kept for the entire qos-test run. We can change each test to clean after themselves. This approach would make the 'create' tests obsolete since we would need to create and delete dirs/files/symlinks for the cleanup, turning them into the 'unlinkat' tests that comes right after. We chose a different approach that handles the root cause: do not use constructor/destructor to create the temp dir. Create one temp dir for each test, and remove it after the test is complete. This is the approach taken for other qtests like vhost-user-test.c where each test requires a setup() and a subsequent cleanup(), all of those instantiated in the .before callback.
