block: Fix deadlocks in bdrv_graph_wrunlock()
bdrv_graph_wrunlock() calls aio_poll(), which may run callbacks that have a nested event loop. Nested event loops can depend on other iothreads making progress, so in order to allow them to make progress it must not hold the AioContext lock of another thread while calling aio_poll().
This introduces a @bs parameter to bdrv_graph_wrunlock() whose AioContext is temporarily dropped (which matches bdrv_graph_wrlock()), and a bdrv_graph_wrunlock_ctx() that can be used if the BlockDriverState doesn't necessarily exist any more when unlocking.
This also requires a change to bdrv_schedule_unref(), which was relying on the incorrectly taken lock. It needs to take the lock itself now. While this is a separate bug, it can't be fixed a separate patch because otherwise the intermediate state would either deadlock or try to release a lock that we don't even hold.

block-coroutine-wrapper: Take AioContext lock in no_co_wrappers
All of the functions that currently take a BlockDriverState, BdrvChild or BlockBackend as their first parameter expect the associated AioContext to be locked when they are called. In the case of no_co_wrappers, they are called from bottom halves directly in the main loop, so no other caller can be expected to take the lock for them. This can result in assertion failures because a lock that isn't taken is released in nested event loops.
Looking at the first parameter is already done by co_wrappers to decide where the coroutine should run, so doing the same in no_co_wrappers is only consistent. Take the lock in the generated bottom halves to fix the problem.

block-coroutine-wrapper: Introduce no_co_wrapper
Some functions must not be called from coroutine context. The common pattern to use them anyway from a coroutine is running them in a BH and letting the calling coroutine yield to be woken up when the BH is completed.
Instead of manually writing such wrappers, add support for generating them to block-coroutine-wrapper.

I believe these go back to Emanuele's reorganization of the block API, merged a few months ago in commit d7e2fe4aac8.
Fortunately, breaking them is merely a matter of deleting unnecessary includes from headers, and adding them back in places where they are now missing.

This "_bdrv
block-coroutine-wrapper.py: introduce annotations that take the graph rdlock
Add co_wrapper_bdrv_rdlock and co_wrapper_mixed_bdrv_rdlock option to the block-coroutine-wrapper.py script.
This "_bdrv_rdlock" option takes and releases the graph rdlock when a coroutine function is created.
This means that when used together with "_mixed", the function marked with co_wrapper_mixed_bdrv_rdlock will support both coroutine and non-coroutine case, and in the latter case it will create a coroutine that takes and releases the rdlock. When called from a coroutine, the caller must already hold the graph lock.
Example: void co_wrapper_mixed_bdrv_rdlock bdrv_f1();
Becomes
static void bdrv_co_enter_f1() { bdrv_graph_co_rdlock(); bdrv_co_function(); bdrv_graph_co_rdunlock(); }
void bdrv_f1() { if (qemu_in_coroutine) { assume_graph_lock(); bdrv_co_function(); } else { qemu_co_enter(bdrv_co_enter_f1); ... } }
When used alone, the function will not work in coroutine context, and when called in non-coroutine context it will create a new coroutine that takes care of taking and releasing the rdlock automatically.
Example: void co_wrapper_bdrv_rdlock bdrv_f1();
Becomes
static void bdrv_co_enter_f1() { bdrv_graph_co_rdlock(); bdrv_co_function(); bdrv_graph_co_rdunlock(); }
void bdrv_f1() { assert(!qemu_in_coroutine()); qemu_co_enter(bdrv_co_enter_f1); ... }
About their usage: - co_wrapper does not take the rdlock, so it can be used also outside the block layer. - co_wrapper_mixed will be used by many blk_* functions, since the coroutine function needs to call blk_wait_while_drained() and the rdlock *must* be taken afterwards, otherwise it's a deadlock. In the future this annotation will go away, and blk_* will use co_wrapper directly. - co_wrapper_bdrv_rdlock will be used by BlockDriver callbacks, ideally by all of them in the future. - co_wrapper_mixed_bdrv_rdlock will be used by the remaining functions that are still called by coroutine and non-coroutine context. In the future this annotation will go away, as we will split such mixed functions.

block-coroutine-wrapper.py: support functions without bs arg
Right now, we take the first parameter of the function to get the BlockDriverState to pass to bdrv_poll_co(), that internally calls functions that figure in which aiocontext the coroutine should run.
However, it is useless to pass a bs just to get its own AioContext, so instead pass it directly, and default to the main loop if no BlockDriverState is passed as parameter.

block-coroutine-wrapper.py: introduce co_wrapper
This new annotation starts just a function wrapper that creates a new coroutine. It assumes the caller is not a coroutine. It will be the default annotation to be used in the future.
This is much better as c_w_mixed, because it is clear if the caller is a coroutine or not, and provides the advantage of automating the code creation. In the future all c_w_mixed functions will be substituted by co_wrapper.

Merge remote-tracking branch 'remotes/stefanha-gitlab/tags/block-pull-request' into staging Pull request v2: * Removed clang-format call from scripts/block-coroutine-wrapper.py
Merge remote-tracking branch 'remotes/stefanha-gitlab/tags/block-pull-request' into staging Pull request v2: * Removed clang-format call from scripts/block-coroutine-wrapper.py. This avoids the issue with clang version incompatibility. It could be added back in the future but the code is readable without reformatting and it also makes the build less dependent on the environment. # gpg: Signature made Mon 05 Oct 2020 16:42:28 BST # gpg: using RSA key 8695A8BFD3F97CDAAC35775A9CA4ABB381AB73C8 # gpg: Good signature from "Stefan Hajnoczi <stefanha@redhat.com>" [full] # gpg: aka "Stefan Hajnoczi <stefanha@gmail.com>" [full] # Primary key fingerprint: 8695 A8BF D3F9 7CDA AC35 775A 9CA4 ABB3 81AB 73C8 * remotes/stefanha-gitlab/tags/block-pull-request: util/vfio-helpers: Rework the IOVA allocator to avoid IOVA reserved regions util/vfio-helpers: Collect IOVA reserved regions docs: add 'io_uring' option to 'aio' param in qemu-options.hx include/block/block.h: drop non-ascii quotation mark block/io: refactor save/load vmstate block: drop bdrv_prwv block: generate coroutine-wrapper code scripts: add block-coroutine-wrapper.py block: declare some coroutine functions in block/coroutines.h block/io: refactor coroutine wrappers block: return error-code from bdrv_invalidate_cache block/nvme: Replace magic value by SCALE_MS definition block/nvme: Use register definitions from 'block/nvme.h' block/nvme: Drop NVMeRegs structure, directly use NvmeBar block/nvme: Reduce I/O registers scope block/nvme: Map doorbells pages write-only util/vfio-helpers: Pass page protections to qemu_vfio_pci_map_bar() Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
