Future versions ++of Linux may add additional fields to the end of this structure. ++ ++ ++Users need to obtain the address of the restartable sequences area using ++the thread pointer and the @code{__rseq_offset} variable, described ++below. ++ ++One use of the restartable sequences area is to read the current CPU ++number from its @code{cpu_id} field, as an inline version of ++@code{sched_getcpu}. @Theglibc{} sets the @code{cpu_id} field to ++@code{RSEQ_CPU_ID_REGISTRATION_FAILED} if registration failed or was ++explicitly disabled. ++ ++Furthermore, users can store the address of a @code{struct rseq_cs} ++object into the @code{rseq_cs} field of @code{struct rseq}, thus ++informing the kernel that the thread enters a restartable sequence ++critical section. This pointer and the code areas it itself points to ++must not be left pointing to memory areas which are freed or re-used. ++Several approaches can guarantee this. If the application or library ++can guarantee that the memory used to hold the @code{struct rseq_cs} and ++the code areas it refers to are never freed or re-used, no special ++action must be taken. Else, before that memory is re-used of freed, the ++application is responsible for setting the @code{rseq_cs} field to ++@code{NULL} in each thread's restartable sequence area to guarantee that ++it does not leak dangling references. Because the application does not ++typically have knowledge of libraries' use of restartable sequences, it ++is recommended that libraries using restartable sequences which may end ++up freeing or re-using their memory set the @code{rseq_cs} field to ++@code{NULL} before returning from library functions which use ++restartable sequences. ++ ++The manual for the @code{rseq} system call can be found ++at @uref{https://git.kernel.org/pub/scm/libs/librseq/librseq.git/tree/doc/man/rseq.2}. ++@end deftp ++ ++@deftypevar {int} __rseq_offset ++@standards{Linux, sys/rseq.h} ++This variable contains the offset between the thread pointer (as defined ++by @code{__builtin_thread_pointer} or the thread pointer register for ++the architecture) and the restartable sequences area.
