Since commit 262a69f428 ("osdep.h: Prohibit disabling assert() in supported builds") 'NDEBUG' can not be defined, so '#ifndef NDEBUG' is dead code. Remove it.

2023-02-23block/rbd: Add support for layered encryptionOr Ozeri
Starting from ceph Reef, RBD has built-in support for layered encryption, where each ancestor image (in a cloned image setting) can be possibly encrypted using a unique passphrase. A new function, rbd_encryption_load2, was added to librbd API. This new function supports an array of passphrases (via "spec" structs). This commit extends the qemu rbd driver API to use this new librbd API, in order to support this new layered encryption feature.

2023-02-23block/rbd: Add luks-any encryption opening optionOr Ozeri
Ceph RBD encryption API required specifying the encryption format for loading encryption. The supported formats were LUKS (v1) and LUKS2. Starting from Reef release, RBD also supports loading with "luks-any" format, which works for both versions of LUKS. This commit extends the qemu rbd driver API to enable qemu users to use this luks-any wildcard format.

This adds GRAPH_RDLOCK annotations to declare that callers of bdrv_co_is_inserted() need to hold a reader lock for the graph. blk_is_inserted() is done as a co_wrapper_mixed_bdrv_rdlock (unlike most other blk_* functions) because it is called a lot from other blk_co_*() functions that already hold the lock. These calls go through blk_is_available(), which becomes a co_wrapper_mixed_bdrv_rdlock, too, for the same reason. Functions that run in a coroutine and can call bdrv_co_is_available() directly are changed to do so, which results in better TSA coverage.

2023-02-23mirror: Fix access of uninitialised fields during startKevin Wolf
bdrv_mirror_top_pwritev() accesses the job object when active mirroring is enabled. It disables this code during early initialisation while s->job isn't set yet. However, s->job is still set way too early when the job object isn't fully initialised. For example, &s->ops_in_flight isn't initialised yet and the in_flight bitmap doesn't exist yet. This causes crashes when a write request comes in too early. Move the assignment of s->job to when the mirror job is actually fully initialised to make sure that the mirror_top driver doesn't access it too early.

2023-02-17block/file-posix: don't use functions calling AIO_WAIT_WHILE in worker threadsEmanuele Giuseppe Esposito
When calling bdrv_getlength() in handle_aiocb_write_zeroes(), the function creates a new coroutine and then waits that it finishes using AIO_WAIT_WHILE. The problem is that this function could also run in a worker thread, that has a different AioContext from main loop and iothreads, therefore in AIO_WAIT_WHILE we will have in_aio_context_home_thread(ctx) == false and therefore assert(qemu_get_current_aio_context() == qemu_get_aio_context()); in the else branch will fail, crashing QEMU. Aside from that, bdrv_getlength() is wrong also conceptually, because it reads the BDS graph from another thread and is not protected by any lock. Replace it with raw_co_getlength, that doesn't create a coroutine and doesn't read the BDS graph.

.bdrv_co_create implementations run in a coroutine. Therefore they are not allowed to open images directly. Fix the calls to use the corresponding no_co_wrappers instead.

2023-02-17block: Create no_co_wrappers for open functionsKevin Wolf
Images can't be opened in coroutine context because opening needs to change the block graph. Add no_co_wrappers so that coroutines have a simple way of opening images in a BH instead. At the same time, mark the wrapped functions as no_coroutine_fn.

2023-02-17curl: Fix error path in curl_open()Hanna Czenczek
g_hash_table_destroy() and g_hash_table_foreach_remove() (called by curl_drop_all_sockets()) both require the table to be non-NULL, or will print assertion failures (just print, no abort). There are several paths in curl_open() that can lead to the out_noclean label without s->sockets being allocated, so clean it only if it has been allocated. Example reproducer: $ qemu-img info -f http '' qemu-img: GLib: g_hash_table_foreach_remove: assertion 'hash_table != NULL' failed qemu-img: GLib: g_hash_table_destroy: assertion 'hash_table != NULL' failed qemu-img: Could not open '': http curl driver cannot handle the URL '' (does not start with 'http://') Closes: https://gitlab.com/qemu-project/qemu/-/issues/1475 Suggested-by: Daniel P.

2023-02-09block: fix detect-zeroes= with BDRV_REQ_REGISTERED_BUFStefan Hajnoczi
When a write request is converted into a write zeroes request by the detect-zeroes= feature, it is no longer associated with an I/O buffer. The BDRV_REQ_REGISTERED_BUF flag doesn't make sense without an I/O buffer and must be cleared because bdrv_co_do_pwrite_zeroes() fails with -EINVAL when it's set. Fiona Ebner <f.ebner@proxmox.com> bisected and diagnosed this QEMU 7.2 regression where writes containing zeroes to a blockdev with discard=unmap,detect-zeroes=unmap fail.

2023-02-01qemu-img: Change info key names for protocol nodesHanna Reitz
Currently, when querying a qcow2 image, qemu-img info reports something like this: image: test.qcow2 file format: qcow2 virtual size: 64 MiB (67108864 bytes) disk size: 196 KiB cluster_size: 65536 Format specific information: compat: 1.1 compression type: zlib lazy refcounts: false refcount bits: 16 corrupt: false extended l2: false Child node '/file': image: test.qcow2 file format: file virtual size: 192 KiB (197120 bytes) disk size: 196 KiB Format specific information: extent size hint: 1048576 Notably, the way the keys are named is specific for image files: The filename is shown under "image", the BDS driver under "file format", and the BDS length under "virtual size". This does not make much sense for nodes that are not actually supposed to be guest images, like the /file child node shown above. Give bdrv_node_info_dump() a @protocol parameter that gives a hint that the respective node is probably just used for data storage and does not necessarily present the data for a VM guest disk. This renames the keys so that with this patch, the output becomes: image: test.qcow2 [...] Child node '/file': filename: test.qcow2 protocol type: file file length: 192 KiB (197120 bytes) disk size: 196 KiB Format specific information: extent size hint: 1048576 (Perhaps we should also rename "Format specific information", but I could not come up with anything better that will not become problematic if we guess wrong with the protocol "heuristic".) This change affects iotest 302, which has protocol node information in its reference output.
