MFC: Change the ABI of some of the structures used by the SYSV IPC API:

2009-07-31T20:32:55Z

- Various members of struct ipc_perm use appropriate types instead of unsigned short. - The shm_segsz member of struct shmid_ds is now a size_t instead of an int which should allow for complete support of SYSV SHM regions >= 2GB. - The shm_nattch member of struct shmid_ds is now an int instead of a short. - The existing versions of the __semctl(), msgctl(), and shmctl() system calls have been renamed to freebsd7_*() and implement the old ABI. New versions of these system calls provide the new ABI. The new system calls also use newer symbol versions in libc so old and new binaries will both work under new kernels. - Specific to 7.x: the kern_msgctl(), kern_semctl(), and kern_shmctl() functions now use ABI shims that transparently "rename" the functions to kern_new_*() for all new modules. Existing compat functions under the old names remain to provide compatibility for older kernel modules.

Make linux_sendmsg() and linux_recvmsg() work on linux32/amd64. Change types used in the linux' struct msghdr and struct cmsghdr definitions to the properly-sized architecture-specific types. Move ancillary data handler from linux_sendit() to linux_sendmsg(). Approved by: kib (mentor)

Somewhere between 2.6.23 and 2.6.27, Linux added SOCK_CLOEXEC and SOCK_NONBLOCK flags, that allow to save fcntl() calls. Implement a variation of the socket() syscall which takes a flags in addition to the type argument. Approved by: kib (mentor)

MFC r192205:

2009-06-16T05:08:48Z

Return EINVAL in case when the incorrect or unsupported type argument is specified. Do not map type argument value as its Linux values are identical to FreeBSD values. Approved by: kib (mentor)

Use the protocol family constants for the domain argument validation. Return immediately when the socket() failed. Approved by: kib (mentor)

Emulate SO_PEERCRED socket option. Temporarily use 0 for pid member as the FreeBSD does not cache remote UNIX domain socket peer pid. PR: kern/102956 Approved by: kib (mentor)
