As was pointed out by
0e2e54966af5 ("mm: fix public declaration of
struct xen_mem_acquire_resource"), we're not currently handling structs
correctly that have uint64_aligned_t fields. #pragma pack(4) suppresses
the necessary alignment even if the type did properly survive (which
it also didn't) in the process of generating the headers. Overall,
with the above mentioned change applied, there's only a latent issue
here afaict, i.e. no other of our interface structs is currently
affected.
As a result it is clear that using #pragma pack(4) is not an option.
Drop all uses from compat header generation. Make sure
{,u}int64_aligned_t actually survives, such that explicitly aligned
fields will remain aligned. Arrange for {,u}int64_t to be transformed
into a type that's 64 bits wide and 4-byte aligned, by utilizing that
in typedef-s the "aligned" attribute can be used to reduce alignment.
Additionally, for the cases where native structures get re-used,
enforce suitable alignment via typedef-s (which allow alignment to be
reduced).
This use of typedef-s makes necessary changes to CHECK_*() macro
generation: Previously get-fields.sh relied on finding struct/union
keywords when other compound types were used. We need to use the
typedef-s (guaranteeing suitable alignment) now, and hence the script
has to recognize those cases, too. (Unfortunately there are a few
special cases to be dealt with, but this is really not much different
from e.g. the pre-existing compat_domain_handle_t special case.)
This need to use typedef-s is certainly somewhat fragile going forward,
as in similar future cases it is imperative to also use typedef-s, or
else the CHECK_*() macros won't check what they're supposed to check. I
don't currently see any means to avoid this fragility, though.
There's one change to generated code according to my observations: In
arch_compat_vcpu_op() the runstate area "area" variable would previously
have been put in a just 4-byte aligned stack slot (despite being 8 bytes
in size), whereas now it gets put in an 8-byte aligned location.
There also results some curious inconsistency in struct xen_mc from
these changes - I intend to clean this up later on. Otherwise unrelated
code would also need adjustment right here.
Additionally a note about the apparently superfluous () in
compat-build-header.py: The simpler form
[ r"typedef(.*)@KeeP@(xen_?)?([\w]+)([^\w])",
r"typedef\1\2\3 __attribute__((__aligned__(__alignof(\1compat_\3))))\4" ],
upsets Python up to at least 3.4.6, claiming to be unable to find the
expansion of \2 (at least when it's empty).
