src/sys/compat/linux/linux_emul.h, branch releng/7.3 FreeBSD source tree Merge r191269 from HEAD to stable/7: 2009-05-25T14:36:21+00:00 Dmitry Chagin dchagin@FreeBSD.org 2009-05-25T14:36:21+00:00 ec54525f084ea191cf988d76b88650e8a1b3fb8a Remove support for FUTEX_REQUEUE operation. Glibc does not use this operation since 2.3.3 version (Jun 2004), as it is racy and replaced by FUTEX_CMP_REQUEUE operation. Glibc versions prior to 2.3.3 fall back to FUTEX_WAKE when FUTEX_REQUEUE returned EINVAL. Any application directly using FUTEX_REQUEUE without return value checking are definitely broken. Limit quantity of messages per process about unsupported operation. Approved by: kib(mentor) 
Remove support for FUTEX_REQUEUE operation.

FUTEX_REQUEUE returned EINVAL.

Any application directly using FUTEX_REQUEUE without return
value checking are definitely broken.

Limit quantity of messages per process about unsupported
operation.

Most of the code is modelled after what Linux does. This is because robust futexes are mostly userspace thing which we cannot alter. Two syscalls maintain pointer to userspace list and when process exits a routine walks this list waking up processes sleeping on futexes from that list. r183871: Make robust futexes work on linux32/amd64. Use PTRIN to read user-mode pointers. Change types used in the structures definitions to properly-sized architecture-specific types. r185002: In the robust futexes list head, futex_offset shall be signed, and glibc actually supplies negative offsets. Change l_ulong to l_long. Approved by: kib (mentor)
