2023-10-04osdep: set _FORTIFY_SOURCE=2 when optimization is enabledDaniel P. Berrangé2-4/+4
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to just check the __OPTIMIZE__ define from osdep.h. The comment about being incompatible with clang appears to be outdated, as compilation works fine without excluding clang.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.

2023-09-20block: remove AIOCBInfo->get_aio_context()Stefan Hajnoczi1-8/+0
The synchronous bdrv_aio_cancel() function needs the acb's AioContext so it can call aio_poll() to wait for cancellation. It turns out that all users run under the BQL in the main AioContext, so this callback is not needed. Remove the callback, mark bdrv_aio_cancel() GLOBAL_STATE_CODE just like its blk_aio_cancel() caller, and poll the main loop AioContext. The purpose of this cleanup is to identify bdrv_aio_cancel() as an API that does not work with the multi-queue block layer.

2023-09-07io: follow coroutine AioContext in qio_channel_yield()Stefan Hajnoczi1-7/+20
The ongoing QEMU multi-queue block layer effort makes it possible for multiple threads to process I/O in parallel. The nbd block driver is not compatible with the multi-queue block layer yet because QIOChannel cannot be used easily from coroutines running in multiple threads. This series changes the QIOChannel API to make that possible. In the current API, calling qio_channel_attach_aio_context() sets the AioContext where qio_channel_yield() installs an fd handler prior to yielding: qio_channel_attach_aio_context(ioc, my_ctx); ... qio_channel_yield(ioc); // my_ctx is used here ... qio_channel_detach_aio_context(ioc); This API design has limitations: reading and writing must be done in the same AioContext and moving between AioContexts involves a cumbersome sequence of API calls that is not suitable for doing on a per-request basis. There is no fundamental reason why a QIOChannel needs to run within the same AioContext every time qio_channel_yield() is called. QIOChannel only uses the AioContext while inside qio_channel_yield(). The rest of the time, QIOChannel is independent of any AioContext. In the new API, qio_channel_yield() queries the AioContext from the current coroutine using qemu_coroutine_get_aio_context(). There is no need to explicitly attach/detach AioContexts anymore and qio_channel_attach_aio_context() and qio_channel_detach_aio_context() are gone. One coroutine can read from the QIOChannel while another coroutine writes from a different AioContext. This API change allows the nbd block driver to use QIOChannel from any thread. It's important to keep in mind that the block driver already synchronizes QIOChannel access and ensures that two coroutines never read simultaneously or write simultaneously. This patch updates all users of qio_channel_attach_aio_context() to the new API. Most conversions are simple, but vhost-user-server requires a new qemu_coroutine_yield() call to quiesce the vu_client_trip() coroutine when not attached to any AioContext. While the API is has become simpler, there is one wart: QIOChannel has a special case for the iohandler AioContext (used for handlers that must not run in nested event loops). I didn't find an elegant way preserve that behavior, so I added a new API called qio_channel_set_follow_coroutine_ctx(ioc, true|false) for opting in to the new AioContext model. By default QIOChannel uses the iohandler AioHandler. Code that formerly called qio_channel_attach_aio_context() now calls qio_channel_set_follow_coroutine_ctx(ioc, true) once after the QIOChannel is created.

2023-08-09util/interval-tree: Check root for null in interval_tree_iter_firstHelge Deller1-1/+1
Fix a crash in qemu-user when running cat /proc/self/maps in a chroot, where /proc isn't mounted. The problem was introduced by commit 3ce3dd8ca965 ("util/selfmap: Rewrite using qemu/interval-tree.h") where in open_self_maps_1() the function read_self_maps() is called and which returns NULL if it can't read the hosts /proc/self/maps file. Afterwards that NULL is fed into interval_tree_iter_first() which doesn't check if the root node is NULL. Fix it by adding a check if root is NULL and return NULL in that case.

While less susceptible to optimization problems than left and right, interval_tree_iter_next also reads rb_parent(), so make sure that stores and loads are atomic. This goes further than technically required, changing all loads to be atomic, rather than simply the ones in the iteration side. But it doesn't really affect the code generation on the rebalance side and is cleaner to handle everything the same.
