In order to maximize the re-usability of kernel code in user space this patch modifies makesyscalls.sh to prefix all of the non-compatibility calls (e.g. not linux_, freebsd32_) with sys_ and updates the kernel entry points and all places in the code that use them. It also fixes an additional name space collision between the kernel function psignal and the libc function of the same name by renaming the kernel psignal kern_psignal(). By introducing this change now we will ease future MFCs that change syscalls.

Second-to-last commit implementing Capsicum capabilities in the FreeBSD kernel for FreeBSD 9.0:
Add a new capability mask argument to fget(9) and friends, allowing system call code to declare what capabilities are required when an integer file descriptor is converted into an in-kernel struct file *. With options CAPABILITIES compiled into the kernel, this enforces capability protection; without, this change is effectively a no-op.
Some cases require special handling, such as mmap(2), which must preserve information about the maximum rights at the time of mapping in the memory map so that they can later be enforced in mprotect(2) -- this is done by narrowing the rights in the existing max_protection field used for similar purposes with file permissions.
In namei(9), we assert that the code is not reached from within capability mode, as we're not yet ready to enforce namespace capabilities there. This will follow in a later commit.
Update two capability names: CAP_EVENT and CAP_KEVENT become CAP_POST_KEVENT and CAP_POLL_KEVENT to more accurately indicate what they represent.

Restore binary compatibility for GIO_KEYMAP and PIO_KEYMAP.
Back in 2009 I changed the ABI of the GIO_KEYMAP and PIO_KEYMAP ioctls to support wide characters. I created a patch to add ABI compatibility for the old calls, but I didn't get any feedback to that.
It seems now people are upgrading from 8 to 9 they experience this issue, so add it anyway.

Burn TTY ioctl bridges in compat layers.
I really don't want any pieces of code to include ioctl_compat.h, so let the ibcs2 and svr4 compat leave sgtty alone. If they want to support sgtty, they should emulate it on top of termios, not sgtty.
The code has been marked with BURN_BRIDGES for a long time. ibcs2 and svr4 are not really popular pieces of code anyway.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system.
The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following:
- Improved driver model:
The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers.
If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver.
- Improved hotplugging:
With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc).
The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly.
- Improved performance:
One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters.
Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

In continuation of early fileop credential changes, modify fo_ioctl() to accept an 'active_cred' argument reflecting the credential of the thread initiating the ioctl operation.
- Change fo_ioctl() to accept active_cred; change consumers of the fo_ioctl() interface to generally pass active_cred from td->td_ucred. - In fifofs, initialize filetmp.f_cred to ap->a_cred so that the invocations of soo_ioctl() are provided access to the calling f_cred. Pass ap->a_td->td_ucred as the active_cred, but note that this is required because we don't yet distinguish file_cred and active_cred in invoking VOP's. - Update kqueue_ioctl() for its new argument. - Update pipe_ioctl() for its new argument, pass active_cred rather than td_ucred to MAC for authorization. - Update soo_ioctl() for its new argument. - Update vn_ioctl() for its new argument, use active_cred rather than td->td_ucred to authorize VOP_IOCTL() and the associated VOP_GETATTR().

Lock struct pgrp, session and sigio.
New locks are:
- pgrpsess_lock which locks the whole pgrps and sessions, - pg_mtx which protects the pgrp members, and - s_mtx which protects the session members.
Please refer to sys/proc.h for the coverage of these locks.
Changes on the pgrp/session interface:
- pgfind() needs the pgrpsess_lock held.
- The caller of enterpgrp() is responsible to allocate a new pgrp and session.
- Call enterthispgrp() in order to enter an existing pgrp.
- pgsignal() requires a pgrp lock held.

SMP Lock struct file, filedesc and the global file list.
Seigo Tanimura (tanimura) posted the initial delta.
I've polished it quite a bit reducing the need for locking and adapting it for KSE.
Locks:
1 mutex in each filedesc protects all the fields. protects "struct file" initialization, while a struct file is being changed from &badfileops -> &pipeops or something the filedesc should be locked.
1 mutex in each struct file protects the refcount fields. doesn't protect anything else. the flags used for garbage collection have been moved to f_gcflag which was the FILLER short, this doesn't need locking because the garbage collection is a single threaded container. could likely be made to use a pool mutex.
1 sx lock for the global filelist.
struct file * fhold(struct file *fp); /* increments reference count on a file */
struct file * fhold_locked(struct file *fp); /* like fhold but expects file to locked */
struct file * ffind_hold(struct thread *, int fd); /* finds the struct file in thread, adds one reference and returns it unlocked */
struct file * ffind_lock(struct thread *, int fd); /* ffind_hold, but returns file locked */
I still have to smp-safe the fget cruft, I'll get to that asap.

This is what was "fdfix2.patch," a fix for fd sharing. It's pretty far-reaching in fd-land, so you'll want to consult the code for changes. The biggest change is that now, you don't use fp->f_ops->fo_foo(fp, bar) but instead fo_foo(fp, bar), which increments and decrements the fp refcount upon entry and exit. Two new calls, fhold() and fdrop(), are provided. Each does what it seems like it should, and if fdrop() brings the refcount to zero, the fd is freed as well.
Thanks to peter ("to hell with it, it looks ok to me.") for his review. Thanks to msmith for keeping me from putting locks everywhere :)

This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change.

Remove old files no longer needed. Add new files created for emulator. Modify NetBSD import to work with FreeBSD and add new features and code. The complete emulator is essentially a combination of work/code implemented by Sean Eric Fagan, Soren Schmidt, Scott Bartram, and myself, Steven Wallace.
Features of this new emulator system include:
o "clean" code, including strict prototyping. o Auto-generation of ibcs2 system calls, xenix system calls, isc system calls. Generation includes system tables, structure definitions, and prototyping of function calls. o ibcs2 emulator does not rely on any COMPAT_43 system calls. o embedded socksys support o ibcs2 msgsys, semsys, shmsys calls supported if supported in kernel o alternate /emul/ibcs2 namespace searched first for files in ibcs2 system. Usefull to keep sysv libraries, binaries in /emul/ibcs2. o many other finer details and functions fixed or implemented.
