semctl09 broken on 32bit powerpc (and 64bit time)

1

For some reason, semctl09 fails unless compiled with -O0. ``` semctl09.c:141: TINFO: Test SEM_STAT_ANY with nobody user semctl09.c:163: TPASS: SEM_INFO returned valid index 10 to semid 10 semctl09.c:175: TFAIL: Counted...

shmctl06 not portable to 32-bit powerpc + 64bit time

3

The test uses ``` struct shmid64_ds buf_ds = { .shm_atime_high = 0x0A0A, .shm_dtime_high = 0x0A0A, .shm_ctime_high = 0x0A0A, }; ``` from linux, but in case of powerpc, it's this: https://github.com/torvalds/linux/blob/master/arch/powerpc/include/uapi/asm/shmbuf.h...

ioctl07 fails on powerpc

1

The test calls ioctl with invalid address (-1), however https://github.com/lattera/glibc/blob/master/sysdeps/unix/sysv/linux/tcgetattr.c called from the ioctl wrapper https://github.com/lattera/glibc/blob/master/sysdeps/unix/sysv/linux/powerpc/ioctl.c has no safeguards against bad address and causes some stack damage or whatever: ```...

5

Summary: When running ioctl_fiemap01 on ext2, the test fails because it expects EBADR (53) when passing an invalid FIEMAP structure, but the kernel returns EINVAL (22) instead. This behavior is...

openat02: Run on TMPDIR with noatime and relatime

2

openat02 requires to use TMPDIR mounted with `noatime` and `relatime` otherwise it `TCONF`. This works on `tmpfs` but not on `/var/tmp` on btrfs on Tumbleweed with kernel 6.15: https://openqa.opensuse.org/tests/5088823#step/openat02/8 ```...
