various: general adoption of SPDX licensing ID tags.

2017-11-27T15:37:16Z

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. No functional change intended.

ipcs: fix warnings (WARNS=1 -> WARNS=6)

- fix shadow warnings - change type from off_t to size_t which is more correct and avoids signed/unsigned compare - use new initializer format to avoid "missing values" warning Reviewed by: jhb

option that is highly recommended to be adjusted in too much documentation while doing nothing in FreeBSD since r2729 (rev 1.1). ipcs(1) needs to be recompiled as it is accessing _KERNEL private variables. Reviewed by: jhb (before comment change on linux code) Sponsored by: Sandvine Incorporated

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

2009-06-24T21:10:52Z

- 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.

Add the ability to clean up all shared memory segments which are

unused in one go. From the original PR: I've observed that linux apps running under the linuxulator have a habit of leaving behind shared memory segments which are unused, but which eventually cause the system to run out of free segments and these apps will stop working. ipcrm(1) currently only allows removal of unused message queues, shared memory segments and semaphores on an individual basis, or those having a matching (non-zero) key. However it would often be convenient to just do a complete cleanup of everything, usually as root. PR: bin/118292 Submitted by: Callum Gibson Not reviewed by: grog@ Approved by: grog@
