Extend the support for exempting processes from being killed when swap is exhausted. - Add a new protect(1) command that can be used to set or revoke protection from arbitrary processes. Similar to ktrace it can apply a change to all existing descendants of a process as well as future descendants. - Add a new procctl(2) system call that provides a generic interface for control operations on processes (as opposed to the debugger-specific operations provided by ptrace(2)). procctl(2) uses a combination of idtype_t and an id to identify the set of processes on which to operate similar to wait6(). - Add a PROC_SPROTECT control operation to manage the protection status of a set of processes. MADV_PROTECT still works for backwards compatability. - Add a p_flag2 to struct proc (and a corresponding ki_flag2 to kinfo_proc) the first bit of which is used to track if P_PROTECT should be inherited by new child processes.

Add the wait6(2) system call. It takes POSIX waitid()-like process designator to select a process which is waited for. The system call optionally returns siginfo_t which would be otherwise provided to SIGCHLD handler, as well as extended structure accounting for child and cumulative grandchild resource usage.
Allow to get the current rusage information for non-exited processes as well, similar to Solaris.
The explicit WEXITED flag is required to wait for exited processes, allowing for more fine-grained control of the events the waiter is interested in.
Fix the handling of siginfo for WNOWAIT option for all wait*(2) family, by not removing the queued signal state.

o) Add COMPAT_FREEBSD32 support for MIPS kernels using the n64 ABI with userlands using the o32 ABI. This mostly follows nwhitehorn's lead in implementing COMPAT_FREEBSD32 on powerpc64. o) Add a new type to the freebsd32 compat layer, time32_t, which is time_t in the 32-bit ABI being used. Since the MIPS port is relatively-new, even the 32-bit ABIs use a 64-bit time_t. o) Because time{spec,val}32 has the same size and layout as time{spec,val} on MIPS with 32-bit compatibility, then, disable some code which assumes otherwise wrongly when built for MIPS. A more general macro to check in this case would seem like a good idea eventually. If someone adds support for using n32 userland with n64 kernels on MIPS, then they will have to add a variety of flags related to each piece of the ABI that can vary. That's probably the right time to generalize further. o) Add MIPS to the list of architectures which use PAD64_REQUIRED in the freebsd32 compat code. Probably this should be generalized at some point.

Add the ability for GDB to printout the thread name along with other thread specific informations.
In order to do that, and in order to avoid KBI breakage with existing infrastructure the following semantic is implemented: - For live programs, a new member to the PT_LWPINFO is added (pl_tdname) - For cores, a new ELF note is added (NT_THRMISC) that can be used for storing thread specific, miscellaneous, informations. Right now it is just popluated with a thread name.
GDB, then, retrieves the correct informations from the corefile via the BFD interface, as it groks the ELF notes and create appropriate pseudo-sections.

Rename st_*timespec fields to st_*tim for POSIX 2008 compliance.
A nice thing about POSIX 2008 is that it finally standardizes a way to obtain file access/modification/change times in sub-second precision, namely using struct timespec, which we already have for a very long time. Unfortunately POSIX uses different names.
This commit adds compatibility macros, so existing code should still build properly. Also change all source code in the kernel to work without any of the compatibility macros. This makes it all a less ambiguous.
I am also renaming st_birthtime to st_birthtim, even though it was a local extension anyway. It seems Cygwin also has a st_birthtim.

This renames the COMPAT_IA32 option to COMPAT_FREEBSD32, removes some IA32-specific code from MI parts of the kernel and enhances the freebsd32 compatibility code to support big-endian platforms.

MFp4: Bring in updated jail support from bz_jail branch.
This enhances the current jail implementation to permit multiple addresses per jail. In addtion to IPv4, IPv6 is supported as well. Due to updated checks it is even possible to have jails without an IP address at all, which basically gives one a chroot with restricted process view, no networking,..
SCTP support was updated and supports IPv6 in jails as well.
Cpuset support permits jails to be bound to specific processor sets after creation.
Jails can have an unrestricted (no duplicate protection, etc.) name in addition to the hostname. The jail name cannot be changed from within a jail and is considered to be used for management purposes or as audit-token in the future.
DDB 'show jails' command was added to aid debugging.
Proper compat support permits 32bit jail binaries to be used on 64bit systems to manage jails. Also backward compatibility was preserved where possible: for jail v1 syscalls, as well as with user space management utilities.
Both jail as well as prison version were updated for the new features. A gap was intentionally left as the intermediate versions had been used by various patches floating around the last years.
Bump __FreeBSD_version for the afore mentioned and in kernel changes.
Special thanks to: - Pawel Jakub Dawidek (pjd) for his multi-IPv4 patches and Olivier Houchard (cognet) for initial single-IPv6 patches. - Jeff Roberson (jeff) and Randall Stewart (rrs) for their help, ideas and review on cpuset and SCTP support. - Robert Watson (rwatson) for lots and lots of help, discussions, suggestions and review of most of the patch at various stages. - John Baldwin (jhb) for his help. - Simon L. Nielsen (simon) as early adopter testing changes on cluster machines as well as all the testers and people who provided feedback the last months on freebsd-jail and other channels. - My employer, CK Software GmbH, for the support so I could work on this.

Fix the ones that broke. stat32 had some missing fields from the end and statfs32 was broken due to the strange definition of MNAMELEN (which is dependent on sizeof(long))

Infrastructure tweaks to allow having both an Elf32 and an Elf64 executable handler in the kernel at the same time. Also, allow for the exec_new_vmspace() code to build a different sized vmspace depending on the executable environment. This is a big help for execing i386 binaries on ia64. The ELF exec code grows the ability to map partial pages when there is a page size difference, eg: emulating 4K pages on 8K or 16K hardware pages.
Flesh out the i386 emulation support for ia64. At this point, the only binary that I know of that fails is cvsup, because the cvsup runtime tries to execute code in pages not marked executable.
Obtained from: dfr (mostly, many tweaks from me).
