The new __proc_waitid RPC now expects WEXITED to be passed, allowing to
properly implement waitid, and thus define the missing W* macros
(according to FreeBSD values).
sysvipc: Set ipc_perm mode as mode_t (BZ#18231)2019-10-10T20:33:27ZAdhemerval Zanellaadhemerval.zanella@linaro.org2019-10-10T18:13:11Zurn:sha1:2f959dfe849e0646e27403f2e4091536496ac0f0
This patch sets the mode field in ipc_perm as mode_t for all architectures,
as POSIX specification [1]. The changes required are as follow:
1. It moves the ipc_perm definition out of ipc.h to its own header
ipc_perm.h. It also allows consolidate the IPC_* definition on
only one header.
2. The generic implementation follow the kernel ipc64_perm size so the
syscall can be made directly without temporary buffer copy. However,
since glibc defines the MODE field as mode_t, it omits the __PAD1 field
(since glibc does not export mode_t as 16-bit for any architecture).
It is a two-fold improvement:
2.1. New implementation which follow Linux UAPI will not need to
provide an arch-specific ipc-perm.h header neither wrongly
use the wrong 16-bit definition from previous default ipc.h
(as csky did).
2.1. It allows consolidate ipc_perm definition for architectures that
already provide mode_t as 32-bit.
3. All kernel ABIs for the supported architectures already provides the
expected padding for mode type extension to 32-bit. However, some
architectures the padding has the wrong placement, so it requires
the ipc control routines (msgctl, semctl, and shmctl) to adjust the
mode field accordingly. Currently they are armeb, microblaze, m68k,
s390, and sheb.
A new assume is added, __ASSUME_SYSVIPC_BROKEN_MODE_T, which the
required ABIs define.
4. For the ABIs that define __ASSUME_SYSVIPC_BROKEN_MODE_T, it also
require compat symbols that do not adjust the mode field.
Checked on arm-linux-gnueabihf, aarch64-linux-gnu, powerpc64le-linux-gnu,
and x86_64-linux-gnu. I also checked the sysvipc tests on hppa-linux-gnu,
sh4-linux-gnu, s390x-linux-gnu, and s390-linux-gnu.
I also did a sanity test against armeb qemu usermode for the sysvipc
tests.

We can use long int on sparcv9, but on sparc64, we must match the int
type used by the kernel (and not long int, as in POSIX).

This patch corrects the conformtest expectations for sys/wait.h for
XPG4. This does not change the test results for this header at the
makefile level since it fixes some spurious failures for this header
while introducing other failures previously hidden by incorrect
expectations. However, it shows up issues with stdlib.h for XPG4
defining W* names that are not permitted in this case (previously
wrongly allowed; the W* reservation is UX-shaded in XPG4.2 /
XSI-shaded in POSIX before 2008); that test is thus XFAILed.
Tested for x86_64.
