qapi: Enable enum member introspection to show more than name
The next commit will add feature flags to enum members. There's a
problem, though: query-qmp-schema shows an enum type's members as an
array of member names (SchemaInfoEnum member @values). If it showed
an array of objects with a name member, we could simply add more
members to these objects. Since it's just strings, we can't.
I can see three ways to correct this design mistake:
1. Do it the way we should have done it, plus compatibility goo.
We want a ['SchemaInfoEnumMember'] member in SchemaInfoEnum. Since
changing @values would be a compatibility break, add a new member
@members instead.
@values is now redundant. In my testing, output of
qemu-system-x86_64's query-qmp-schema grows by 11% (18.5KiB).
We can deprecate @values now and drop it later. This will break
outmoded clients. Well-behaved clients such as libvirt are
expected to break cleanly.
2. Like 1, but omit "boring" elements of @member, and empty @member.
@values does not become redundant. @members augments it. Somewhat
cumbersome, but output of query-qmp-schema grows only as we make
enum members non-boring.
There is nothing to deprecate here.
3. Versioned query-qmp-schema.
query-qmp-schema provides either @values or @members. The QMP
client can select which version it wants. There is no redundant
output.
We can deprecate old versions and eventually drop them. This will
break outmoded clients. Breaking cleanly is easier than for 1.
While 1 and 2 operate within the common rules for compatible
evolution apply (section "Compatibility considerations" in
docs/devel/qapi-code-gen.rst), 3 bypasses them. Attractive when
operating within the rules is just too awkward. Not the case here.
This commit implements 1. Libvirt developers prefer it.
Deprecate @values in favour of @members. Since query-qmp-schema
compatibility is pretty fundamental for management applications, an
extended grace period is advised.

Implements deep auto free of arrays while retaining common C-style
squared bracket access. Main purpose of this API is to get rid of
error prone individual array deallocation pathes in user code, i.e.
turning something like this:
void doSomething(size_t n) {
Foo *foos = malloc(n * sizeof(Foo));
for (...) {
foos[i].s = malloc(...);
if (...) {
goto out;
}
}
out:
if (...) {
for (...) {
/* deep deallocation */
free(foos[i].s);
}
/* array deallocation */
free(foos);
}
}
into something more simple and safer like:
void doSomething(size_t n) {
P9ARRAY_REF(Foo) foos = NULL;
P9ARRAY_NEW(Foo, foos, n);
for (...) {
foos[i].s = malloc(...);
if (...) {
return; /* array auto freed here */
}
}
/* array auto freed here */
}
Unlike GArray, P9Array does not require special macros, function
calls or struct member dereferencing to access the individual array
elements:
So existing C-style array code can be retained with only very little
changes; basically limited to replacing array allocation call and of
course removing individual array deallocation pathes.
In this initial version P9Array only supports the concept of unique
pointers, i.e. it does not support reference counting. The array (and
all dynamically allocated memory of individual array elements) is auto
freed once execution leaves the scope of the reference variable (unique
pointer) associated with the array.
Internally a flex array struct is used in combination with macros
spanned over a continuous memory space for both the array's meta data
(private) and the actual C-array user data (public):
struct P9Array##scalar_type {
size_t len; /* private, hidden from user code */
scalar_type first[]; /* public, directly exposed to user code */
};
Which has the advantage that the compiler automatically takes care
about correct padding, alignment and overall size for all scalar data
types on all systems and that the user space exposed pointer can
directly be translated back and forth between user space C-array
pointer and internal P9Array struct whenever needed, in a type-safe
manner.

being used in other C-projects as well. The common QEMU license

When client sent a 9p Tgetattr request then the wrong I/O block
size value was returned by 9p server; instead of host file
system's I/O block size it should rather return an I/O block
size according to 9p session's 'msize' value, because the value
returned to client should be an "optimum" block size for I/O
(i.e. to maximize performance), it should not reflect the actual
physical block size of the underlying storage media.
The I/O block size of a host filesystem is typically 4k, so the
value returned was far too low for good 9p I/O performance.
This patch adds stat_to_iounit() with a similar approach as the
existing get_iounit() function.

virtiofsd: xattr mapping add a new type "unsupported"
Right now for xattr remapping, we support types of "prefix", "ok" or "bad".
Type "bad" returns -EPERM on setxattr and hides xattr in listxattr. For
getxattr, mapping code returns -EPERM but getxattr code converts it to -ENODATA.
I need a new semantics where if an xattr is unsupported, then
getxattr()/setxattr() return -ENOTSUP and listxattr() should hide the xattr.
This is needed to simulate that security.selinux is not supported by
virtiofs filesystem and in that case client falls back to some default
label specified by policy.
So add a new type "unsupported" which returns -ENOTSUP on getxattr() and
setxattr() and hides xattrs in listxattr().
For example, one can use following mapping rule to not support
security.selinux xattr and allow others.

target/riscv: Fix orc.b implementation
The earlier implementation fell into a corner case for bytes that were
0x01, giving a wrong result (but not affecting our application test
cases for strings, as an ASCII value 0x01 is rare in those...).
This changes the algorithm to:
1. Mask out the high-bit of each bytes (so that each byte is <= 127).
2. Add 127 to each byte (i.e. if the low 7 bits are not 0, this will overflow
into the highest bit of each byte).
3. Bitwise-or the original value back in (to cover those cases where the
source byte was exactly 128) to saturate the high-bit.
4. Shift-and-mask (implemented as a mask-and-shift) to extract the MSB of
each byte into its LSB.
5. Multiply with 0xff to fan out the LSB to all bits of each byte.
