- The uid/cuid members of struct ipc_perm are now uid_t instead of unsigned short. - The gid/cgid members of struct ipc_perm are now gid_t instead of unsigned short. - The mode member of struct ipc_perm is now mode_t instead of unsigned short (this is merely a style bug). - The rather dubious padding fields for ABI compat with SV/I386 have been removed from struct msqid_ds and struct semid_ds. - The shm_segsz member of struct shmid_ds is now a size_t instead of an int. This removes the need for the shm_bsegsz member in struct shmid_kernel and 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 shm_internal member of struct shmid_ds is now gone. The internal VM object pointer for SHM regions has been moved into struct shmid_kernel. - The existing __semctl(), msgctl(), and shmctl() system call entries are now marked COMPAT7 and new versions of those system calls which support the new ABI are now present. - The new system calls are assigned to the FBSD-1.1 version in libc. The FBSD-1.0 symbols in libc now refer to the old COMPAT7 system calls. - A simplistic framework for tagging system calls with compatibility symbol versions has been added to libc. Version tags are added to system calls by adding an appropriate __sym_compat() entry to src/lib/libc/incldue/compat.h.
