cpuset: Byte swap cpuset for compat32 on big endian architectures

2022-06-17T19:35:14Z

Summary: BITSET uses long as its basic underlying type, which is dependent on the compile type, meaning on 32-bit builds the basic type is 32 bits, but on 64-bit builds it's 64 bits. On little endian architectures this doesn't matter, because the LSB is always at the low bit, so the words get effectively concatenated moving between 32-bit and 64-bit, but on big-endian architectures it throws a wrench in, as setting bit 0 in 32-bit mode is equivalent to setting bit 32 in 64-bit mode. To demonstrate: 32-bit mode: BIT_SET(foo, 0): 0x00000001 64-bit sees: 0x0000000100000000 cpuset is the only system interface that uses bitsets, so solve this by swapping the integer sub-components at the copyin/copyout points.

Linux has more tolerant checks of the user supplied cpuset_t's. Minimum cpuset_t size that the Linux kernel permits in case of getaffinity() is the maximum CPU id, present in the system / NBBY, the maximum size is not limited. For setaffinity(), Linux does not limit the size of the user-provided cpuset_t, internally using only the meaningful part of the set, where the upper bound is the maximum CPU id, present in the system, no larger than the size of the kernel cpuset_t. Unlike FreeBSD, Linux ignores high bits if set in the setaffinity(), so clear it in the sched_setaffinity() and Linuxulator itself.
