This commit was created with scripts/clean-includes:
./scripts/clean-includes --git include include/*/*.h include/*/*/*.h
All .c should include qemu/osdep.h first. The script performs three
related cleanups:
* Ensure .c files include qemu/osdep.h first.
* Including it in a .h is redundant, since the .c already includes
it. Drop such inclusions.
* Likewise, including headers qemu/osdep.h includes is redundant.
Drop these, too.

The const_le64() macro introduced in commit 845d80a8c7b187 turns out
to have a bug which means that on big-endian systems the compiler
complains if the argument isn't already a 64-bit type. This hasn't
caused a problem yet, because there are no in-tree uses, but it
means it's not possible for anybody to add one without it failing CI.
This example is from an attempted use of it with the argument '0',
from the s390 CI runner's gcc:
../block/blklogwrites.c: In function ‘blk_log_writes_co_do_log’:
../include/qemu/bswap.h:148:36: error: left shift count >= width of
type [-Werror=shift-count-overflow]
148 | ((((_x) & 0x00000000000000ffU) << 56) | \

../block/blklogwrites.c:409:27: note: in expansion of macro ‘const_le64’
409 | .nr_entries = const_le64(0),
| ^~~~~~~~~~
../include/qemu/bswap.h:149:36: error: left shift count >= width of
type [-Werror=shift-count-overflow]
149 | (((_x) & 0x000000000000ff00U) << 40) | \
| ^~
../block/blklogwrites.c:409:27: note: in expansion of macro ‘const_le64’
409 | .nr_entries = const_le64(0),
| ^~~~~~~~~~
cc1: all warnings being treated as errors
Fix this by making all the constants in the macro have the ULL
suffix. This will cause them all to be 64-bit integers, which means
the result of the logical & will also be an unsigned 64-bit type,
even if the input to the macro is a smaller type, and so the shifts
will be in range.

These rather complex functions have never been used since they've been
introduced in 2012, so looks like they are not really useful for QEMU.
And since the static normalize_uri_path() function is also only used by
uri_resolve(), we can remove that function now, too.

uri_string_unescape() basically does the same as the glib function
g_uri_unescape_segment(). So we can get rid of our implementation
completely by simply using the glib function instead.

The Big QEMU Lock (BQL) has many names and they are confusing. The
actual QemuMutex variable is called qemu_global_mutex but it's commonly
referred to as the BQL in discussions and some code comments. The
locking APIs, however, are called qemu_mutex_lock_iothread() and
qemu_mutex_unlock_iothread().
The "iothread" name is historic and comes from when the main thread was
split into into KVM vcpu threads and the "iothread" (now called the main
loop thread). I have contributed to the confusion myself by introducing
a separate --object iothread, a separate concept unrelated to the BQL.
The "iothread" name is no longer appropriate for the BQL. Rename the
locking APIs to:
- void bql_lock(void)
- void bql_unlock(void)
- bool bql_locked(void)
There are more APIs with "iothread" in their names. Subsequent patches
will rename them. There are also comments and documentation that will be
updated in later patches.

The vhost-user-blk export implement AioContext switches in its drain
implementation. This means that on drain_begin, it detaches the server
from its AioContext and on drain_end, attaches it again and schedules
the server->co_trip coroutine in the updated AioContext.
However, nothing guarantees that server->co_trip is even safe to be
scheduled. Not only is it unclear that the coroutine is actually in a
state where it can be reentered externally without causing problems, but
with two consecutive drains, it is possible that the scheduled coroutine
didn't have a chance yet to run and trying to schedule an already
scheduled coroutine a second time crashes with an assertion failure.
Following the model of NBD, this commit makes the vhost-user-blk export
shut down server->co_trip during drain so that resuming the export means
creating and scheduling a new coroutine, which is always safe.
There is one exception: If the drain call didn't poll (for example, this
happens in the context of bdrv_graph_wrlock()), then the coroutine
didn't have a chance to shut down. However, in this case the AioContext
can't have changed; changing the AioContext always involves a polling
drain. So in this case we can simply assert that the AioContext is
unchanged and just leave the coroutine running or wake it up if it has
yielded to wait for the AioContext to be attached again.

It's arguably a bug in Clang since we already use __builtin_assume_aligned()
to tell the compiler that the pointer is properly aligned. But according to
https://github.com/llvm/llvm-project/issues/69146 it seems like the Clang
folks don't see an easy fix on their side and recommend to use a type
declared with __attribute__((aligned(16))) to work around this problem.

Introduce resv_region_list_insert() helper which inserts
a new ReservedRegion into a sorted list of reserved region.
In case of overlap, the new region has higher priority and
hides the existing overlapped segments. If the overlap is
partial, new regions are created for parts which are not
overlapped. The new region has higher priority independently
on the type of the regions.

The networking subsystem may wish to use defer_call(), so move the code
to util/ where it can be reused.
As a reminder of what defer_call() does:
This API defers a function call within a defer_call_begin()/defer_call_end()
section, allowing multiple calls to batch up. This is a performance
optimization that is used in the block layer to submit several I/O requests
at once instead of individually:
defer_call_begin(); <-- start of section
...
defer_call(my_func, my_obj); <-- deferred my_func(my_obj) call
defer_call(my_func, my_obj); <-- another
defer_call(my_func, my_obj); <-- another
...
defer_call_end(); <-- end of section, my_func(my_obj) is called once

osdep: set _FORTIFY_SOURCE=2 when optimization is enabled
Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
|
|
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.

Variables declared in macros can shadow other variables. Much of the
time, this is harmless, e.g.:
#define _FDT(exp) \
do { \
int ret = (exp); \
if (ret < 0) { \
error_report("error creating device tree: %s: %s", \
#exp, fdt_strerror(ret)); \
exit(1); \
} \
} while (0)
Harmless shadowing in h_client_architecture_support():
target_ulong ret;
[...]
ret = do_client_architecture_support(cpu, spapr, vec, fdt_bufsize);
if (ret == H_SUCCESS) {
_FDT((fdt_pack(spapr->fdt_blob)));
[...]
}
return ret;
However, we can get in trouble when the shadowed variable is used in a
macro argument:
#define QOBJECT(obj) ({ \
typeof(obj) o = (obj); \
o ? container_of(&(o)->base, QObject, base) : NULL; \
})
QOBJECT(o) expands into
({
---> typeof(o) o = (o);
o ? container_of(&(o)->base, QObject, base) : NULL;
})
Unintended variable name capture at --->. We'd be saved by
-Winit-self. But I could certainly construct more elaborate death
traps that don't trigger it.
To reduce the risk of trapping ourselves, we use variable names in
macros that no sane person would use elsewhere. Here's our actual
definition of QOBJECT():
#define QOBJECT(obj) ({ \
typeof(obj) _obj = (obj); \
_obj ? container_of(&(_obj)->base, QObject, base) : NULL; \
})
Works well enough until we nest macro calls. For instance, with
#define qobject_ref(obj) ({ \
typeof(obj) _obj = (obj); \
qobject_ref_impl(QOBJECT(_obj)); \
_obj; \
})
the expression qobject_ref(obj) expands into
({
typeof(obj) _obj = (obj);
qobject_ref_impl(
({
---> typeof(_obj) _obj = (_obj);
_obj ? container_of(&(_obj)->base, QObject, base) : NULL;
}));
_obj;
})
Unintended variable name capture at --->.
The only reliable way to prevent unintended variable name capture is
-Wshadow.
One blocker for enabling it is shadowing hiding in function-like
macros like
qdict_put(dict, "name", qobject_ref(...))
qdict_put() wraps its last argument in QOBJECT(), and the last
argument here contains another QOBJECT().
Use dark preprocessor sorcery to make the macros that give us this
problem use different variable names on every call.
