* Rename kernel-only members of semid_ds and msgid_ds.Brooks Davis2018-03-021-4/+4
| | | | | | | | | | | | | | | | | | This deliberately breaks the API in preperation for future syscall revisions which will remove these nonstandard members. In an exp-run a single port (devel/qemu-user-static) was found to use them which it did becuase it emulates system calls. This has been fixed in the ports tree.

* Revert r327005 - SPDX tags for license similar to BSD-2-Clause.Pedro F. Giffuni2017-12-201-2/+0
| | | | | | | | | | | | | | | | | | After consultation with SPDX experts and their matching guidelines[1], the licensing doesn't exactly match the BSD-2-Clause. It yet remains to be determined if they are equivalent or if there is a recognized license that matches but it is safer to just revert the tags. Let this also be a reminder that on FreeBSD, SPDX tags are only advisory and have no legal value (but IANAL).

* sys/sys: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326256
* Change the return type of msgrcv() to ssize_t as required by POSIX.Ed Schouten2016-07-281-2/+1
| | | | | | | | | | It looks like the msgrcv() system call is already written in such a way that the size is internally computed as a size_t and written into all of td_retval[0]. This means that it is effectively already returning ssize_t. It's just that the userspace prototype doesn't match up. Notes: svn path=/head/; revision=303435

* Change the ABI of some of the structures used by the SYSV IPC API:John Baldwin2009-06-241-4/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

| | | | | | | | | | | | | | | message queues, shared memory segments, and semaphores), add a struct label pointer, which will hold the MAC labels for the objects. As a result of recent work to separate kernel and user space ABIs, this should not break the ABI for applications using System V IPC, but will require a rebuild of the ipcs monitoring tool.

* Move the MSG* and SEM* options to opt_sysvipc.hPeter Wemm2000-05-011-57/+5
| | | | | | | | | | | | | | | | | | Remove evil allocation macros from machdep.c (why was that there???) and use malloc() instead. Move paramters out of param.h and into the code itself. Move a bunch of internal definitions from public sys/*.h headers (without #ifdef _KERNEL even) into the code itself. I had hoped to make some of this more dynamic, but the cost of doing wakeups on all sleeping processes on old arrays was too frightening. The other possibility is to initialize on the first use, and allow dynamic sysctl changes to parameters right until that point. That would allow /etc/rc.sysctl to change SEM* and MSG* defaults as we presently do with SHM*, but without the nightmare of changing a running system. Notes: svn path=/head/; revision=59839
