Generate a version string that looks just like a real Linux one - almost :)
Use sbufs everywhere instead of sprintf(). Note that this is still imperfect,
as the code does not check whether the sbuf overflowed - but it'll still
work better than before, since if the sbuf overflows, the code now simply
copies out 0 bytes instead of causing a trap (or worse, corrupting kernel
structures)
of explicit calls to lockmgr. Also provides macros for the flags
pased to specify shared, exclusive or release which map to the
lockmgr flags. This is so that the use of lockmgr can be easily
replaced with optimized reader-writer locks.
- Add some locking that I missed the first time.
waiting for procfs to get fixed:
- Use fill_eproc() to obtain correct VM stats. Attempt to compute VmLib.
- Fill some more fields in proc/<pid>/stat, and add four (unimplemented)
fields after studying a recent Linux kernel.
- Compute CPU frequency only once instead of twice.
- Fix some comments that were OBE.
- Fix indentation except where it makes the code less readable.
process is on the alternate stack or not. For compatibility
with sigstack(2) state is being updated if such is needed.
We now determine whether the process is on the alternate
stack by looking at its stack pointer. This allows a process
to siglongjmp from a signal handler on the alternate stack
to the place of the sigsetjmp on the normal stack. When
maintaining state, this would have invalidated the state
information and causing a subsequent signal to be delivered
on the normal stack instead of the alternate stack.

in the way linux handles connects on non-blocking sockets.

syscall compare against a variable sv_minsigstksz in struct
sysentvec as to properly take the size of the machine- and
ABI dependent struct sigframe into account.
The SVR4 and iBCS2 modules continue to have a minsigstksz of
8192 to preserve behavior. The real values (if different) are
not known at this time. Other ABI modules use the real
values.
The native MINSIGSTKSZ is now defined as follows:

The offset field in struct dirent was set to the offset of
the next dirent in rev 1.36. The offset was calculated from
the current offset and the record length. This offset does
not necessarily match the real offset when we are using
cookies. Therefore, also use the cookies to set the offset
field in struct dirent if we're using cookies to iterate
through the dirents.

Without this patch, an SA_SIGINFO style handler can be installed by a linux
app, but if the handler accesses its sip argument, it will get a garbage
pointer and likely segfault.
We currently supply a valid pointer, but its contents are mainly
garbage. Filling this in properly is future work.

Replace all in-tree uses with necessary subset of <sys/{fb,kb,cons}io.h>.
This is also the appropriate fix for exo-tree sources.
Put warnings in <machine/console.h> to discourage use.
November 15th 2000 the warnings will be converted to errors.
January 15th 2001 the <machine/console.h> files will be removed.
the build (oops!): replace calls to p_trespass() and PRISON_CHECK()
with p_can(..., {P_CAN_SEE, P_CAN_DEBUG}, NULL)
o Remove volatile usage from procfs_readdir() to remove warnings
o Apply bp's CREATE fix to linprocfs, causing EROFS to be returned on
CREATE calls to procfs_lookup()
o Some further synchronization still needs to occur: only existing
access checks were replaced, to fix the build--the new ones were not
added. I'll do this later today, this is a "fix the build quickly"
commit. This means that, in the interim, some information leakage
can still occur via linprocfs when using jail or kern.ps_showallprocs
