2022-10-27block: introduce bdrv_open_file_child() helperVladimir Sementsov-Ogievskiy24-101/+95
Almost all drivers call bdrv_open_child() similarly. Let's create a helper for this. The only not updated drivers that call bdrv_open_child() to set bs->file are raw-format and snapshot-access: raw-format sometimes want to have filtered child but don't set drv->is_filter to true. snapshot-access wants only DATA | PRIMARY Possibly we should implement drv->is_filter_func() handler, to consider raw-format as filter when it works as filter.. But it's another story. Note also, that we decrease assignments to bs->file in code: it helps us restrict modifying this field in further commit.

2022-10-27block: BlockDriver: add .filtered_child_is_backing fieldVladimir Sementsov-Ogievskiy3-0/+15
Unfortunately not all filters use .file child as filtered child. Two exclusions are mirror_top and commit_top. Happily they both are private filters. Bad thing is that this inconsistency is observable through qmp commands query-block / query-named-block-nodes. So, could we just change mirror_top and commit_top to use file child as all other filter driver is an open question. Probably, we could do that with some kind of deprecation period, but how to warn users during it? For now, let's just add a field so we can distinguish them in generic code, it will be used in further commits.

2022-10-27block/io_uring: revert "Use io_uring_register_ring_fd() to skip fd operations"Sam Li2-13/+1
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1193 The commit "Use io_uring_register_ring_fd() to skip fd operations" broke when booting a guest with iothread and io_uring. That is because the io_uring_register_ring_fd() call is made from the main thread instead of IOThread where io_uring_submit() is called. It can not be guaranteed to register the ring fd in the correct thread or unregister the same ring fd if the IOThread is disabled. This optimization is not critical so we will revert previous commit. This reverts commit e2848bc574fe2715c694bf8fe9a1ba7f78a1125a and 77e3f038af1764983087e3551a0fde9951952c4d.

2022-10-27block: Refactor get_tmp_filename()Bin Meng6-34/+38
At present there are two callers of get_tmp_filename() and they are inconsistent. One does: /* TODO: extra byte is a hack to ensure MAX_PATH space on Windows. */ char *tmp_filename = g_malloc0(PATH_MAX + 1); ... ret = get_tmp_filename(tmp_filename, PATH_MAX + 1); while the other does: s->qcow_filename = g_malloc(PATH_MAX); ret = get_tmp_filename(s->qcow_filename, PATH_MAX); As we can see different 'size' arguments are passed. There are also platform specific implementations inside the function, and the use of snprintf is really undesirable. The function name is also misleading. It creates a temporary file, not just a filename. Refactor this routine by changing its name and signature to: char *create_tmp_file(Error **errp) and use g_get_tmp_dir() / g_mkstemp() for a consistent implementation. While we are here, add some comments to mention that /var/tmp is preferred over /tmp on non-win32 hosts.

2022-10-26s390x: pv: Add dump supportJanosch Frank3-33/+246
Sometimes dumping a guest from the outside is the only way to get the data that is needed. This can be the case if a dumping mechanism like KDUMP hasn't been configured or data needs to be fetched at a specific point. Dumping a protected guest from the outside without help from fw/hw doesn't yield sufficient data to be useful. Hence we now introduce PV dump support. The PV dump support works by integrating the firmware into the dump process. New Ultravisor calls are used to initiate the dump process, dump cpu data, dump memory state and lastly complete the dump process. The UV calls are exposed by KVM via the new KVM_PV_DUMP command and its subcommands. The guest's data is fully encrypted and can only be decrypted by the entity that owns the customer communication key for the dumped guest. Also dumping needs to be allowed via a flag in the SE header. On the QEMU side of things we store the PV dump data in the newly introduced architecture ELF sections (storage state and completion data) and the cpu notes (for cpu dump data). Users can use the zgetdump tool to convert the encrypted QEMU dump to an unencrypted one.

2022-10-26accel/tcg: Add restore_state_to_opc to TCGCPUOpsRichard Henderson3-3/+34
Add a tcg_ops hook to replace the restore_state_to_opc function call. Because these generic hooks cannot depend on target-specific types, temporarily, copy the current target_ulong data[] into uint64_t d64[].

2022-10-26accel/tcg: Simplify page_get/alloc_target_dataRichard Henderson3-31/+10
Since the only user, Arm MTE, always requires allocation, merge the get and alloc functions to always produce a non-null result. Also assume that the user has already checked page validity.

2022-10-26accel/tcg: Call tb_invalidate_phys_page for PAGE_RESETRichard Henderson3-14/+11
When PAGE_RESET is set, we are replacing pages with new content, which means that we need to invalidate existing cached data, such as TranslationBlocks. Perform the reset invalidate while we're doing other invalidates, which allows us to remove the separate invalidates from the user-only mmap/munmap/mprotect routines. In addition, restrict invalidation to PAGE_EXEC pages. Since cdf713085131, we have validated PAGE_EXEC is present before translation, which means we can assume that if the bit is not present, there are no translations to invalidate.
