| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even if the caller has both the old and the new AioContext's, there can be a deadlock, due to the leading bdrv_drain_all. Suppose there are four io threads (A, B, A0, B0) with A and B owning a BDS for each (bs_a, bs_b); Now A wants to move bs_a to iothread A0, and B wants to move bs_b to B0, at the same time: iothread A iothread B -------------------------------------------------------------------------- aio_context_acquire(A0) /* OK */ aio_context_acquire(B0) /* OK */ bdrv_set_aio_context(bs_a, A0) bdrv_set_aio_context(bs_b, B0) -> bdrv_drain_all() -> bdrv_drain_all() -> acquire A /* OK */ -> acquire A /* blocked */ -> acquire B /* blocked */ -> acquire B ... ... Deadlock happens because A is waiting for B, and B is waiting for A.

Its error messages aren't helpful here, the caller reports one that actually makes sense. Reproducer: $ qemu-img convert -o backing_format=raw in.img out.img qemu-img: Invalid parameter 'backing_format' qemu-img: Invalid options for file format 'raw' To fix, propagate errors through qemu_opts_do_parse(). This lifts the error reporting into callers. Drop it from img_convert() and img_amend(), keep it in qemu_chr_parse_compat(), bdrv_img_create(). Since I'm touching qemu_opts_do_parse() anyway, write a function comment for it. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qemu_opt_set() is a wrapper around qemu_opt_set() that reports the error with qerror_report_err(). Most of its users assume the function can't fail. Make them use qemu_opt_set_err() with &error_abort, so that should the assumption ever break, it'll break noisily. Just two users remain, in util/qemu-config.c. Switch them to qemu_opt_set_err() as well, then rename qemu_opt_set_err() to qemu_opt_set().

The ramlist mutex is kept. call_rcu callbacks are run with the iothread lock taken, but that may change in the future. Writers still take the ramlist mutex, but they no longer need to assume that the iothread lock is taken. Readers of the list, instead, no longer require either the iothread or ramlist mutex, but they need to use rcu_read_lock() and rcu_read_unlock(). One place in arch_init.c was downgrading from write side to read side like this: qemu_mutex_lock_iothread() qemu_mutex_lock_ramlist() ... qemu_mutex_unlock_iothread() ... qemu_mutex_unlock_ramlist() and the equivalent idiom is: qemu_mutex_lock_ramlist() rcu_read_lock() ... qemu_mutex_unlock_ramlist() ... rcu_read_unlock() Reviewed-by: Fam Zheng <famz@redhat.com> Signed-off-by: Mike Day <ncmike@ncultra.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

That's say tpg is transparent for Qemu, Qemu doesn't know which tpg can boot, but vhost-scsi driver module doesn't know too for one assigned wwpn. At present, we assume that the first tpg can boot only, and add a boot_tpgt property that defaults to 0. Of course, people can pass a valid value by qemu command line.

There are a couple of places where that is infeasible: First, the bdrv_debug_* functions could theoretically be mirrored in the BlockBackend, but since these are functions internal to the block layer, they should not be visible externally (qemu-io as a test tool is exempt from this). Second, bdrv_get_info() and bdrv_get_specific_info() work on a single BDS alone, therefore they should stay BDS-specific. Third, bdrv_is_allocated() mainly works on a single BDS as well. Some data may be passed through from the BDS's file (if sectors which are apparently allocated in the file are not really allocated there but just zero).
