* cpuset: Fix sched_[g|s]etaffinity() for better compatibility with Linux.Dmitry Chagin2023-01-292-2/+2
| | | | | | | | | | | | | | | | | | | | Under Linux to sched_[g|s]etaffinity() functions the value returned from a call to gettid(2) (thread id) can be passed in the argument pid. Specifying pid as 0 will set the attribute for the calling thread, and passing the value returned from a call to getpid(2) (process id) will set the attribute for the main thread of the thread group. Native cpuset(2) family of system calls has "which" argument to determine how the value of id argument is interpreted, i.e., CPU_WHICH_TID is used to pass a thread id and CPU_WHICH_PID - to pass a process id. For now native sched_[g|s]etaffinity() implementation is wrong as uses "which" CPU_WHICH_PID to pass both (process and thread id) to the kernel. To fix this adding a new "which" CPU_WHICH_TIDPID intended to handle both id's. Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D38209 MFC after: 1 week

| | | | | | | | | | | | | | | | | | | | | | | | | | | | glibc-based interface. Unfortunately, the glibc maintainers, despite knowing the existence of the FreeBSD qsort_r(3) interface in 2004 and refused to add the same interface to glibc based on grounds of the lack of standardization and portability concerns, has decided it was a good idea to introduce their own qsort_r(3) interface in 2007 as a GNU extension with a slightly different and incompatible interface. With the adoption of their interface as POSIX standard, let's switch to the same prototype, there is no need to remain incompatible. C++ and C applications written for the historical FreeBSD interface get source level compatibility when building in C++ mode, or when building with a C compiler with C11 generics support, provided that the caller passes a fifth parameter of qsort_r() that exactly matches the historical FreeBSD comparator function pointer type and does not redefine the historical qsort_r(3) prototype in their source code.

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.
