633034fe0e Add FPU_KERN_KTHR flag to fpu_kern_enter(9), which avoids saving FPU
context into memory for the kernel threads which called
fpu_kern_thread(9).  This allows the fpu_kern_enter() callers to not
check for is_fpu_kern_thread() to get the optimization.

Apply the flag to padlock(4) and aesni(4).  In aesni_cipher_process(),
do not leak FPU context state on error.

8cf27a3330 Restore the check for non-NULL dmatag in sndbuf_free.
The sound drivers that use own buffer management can use sndbuf_setup
and not do any busdma allocation, so the driver will end up with the
managed buffer but no valid dma map and tag for it. Avoid calling
bus_dmamem_free in such cases.

efa1aff675 Fix some bugs when fetching probe arguments in i386. Firstly ensure that
the 4 byte-aligned dtrace_invop_callsite can be found and that it
immediately follows the call to dtrace_invop(). Secondly, fix some pointer
arithmetic to account for differences between struct i386_frame and illumos'
struct frame. Finally, ensure that dtrace_getarg() isn't inlined. It works
by following a fixed number of frame pointers to the probe site, so inlining
breaks it.

450570a55e Tidy up fd-related functions called by do_execve
o assert in each one that fdp is not shared
o remove unnecessary NULL checks - all userspace processes have fdtables
and kernel processes cannot execve
o remove comments about the danger of fd_ofiles getting reallocated - fdtable
is not shared and fd_ofiles could be only reallocated if new fd was about to be
added, but if that was possible the code would already be buggy as setugidsafety
work could be undone

8382ec9e6a Fix a couple of bugs on amd64 when fetching probe arguments beyond the
first five for probes entered through a UD fault (i.e. FBT probes).

Specifically, handle the fact that dtrace_invop_callsite must be
16 byte-aligned and thus may not immediately follow the call to
dtrace_invop() in dtrace_invop_start(). Also fetch register arguments and
the stack pointer through a struct trapframe instead of a struct reg.

1cb207df04 Change suggestion how to set MAKESYSPATH as broken incremental build
workaround. Magic ".../share/mk" (search directories up to /)
does not work for f.e. /usr/src/gnu/lib/libgcc because the path
inside is starting from /usr/obj hierarchy and ends up in
/usr/share/mk, not in the /usr/src/share/mk where src.opts.mk is.
IMHO proper fixing of incremental build is needed urgently.

158627616c Don't take filedesc lock in fdunshare().
We can read refcnt safely and only care if it is equal to 1.

If it could suddenly change from 1 to something bigger the code would be
buggy even in the previous form and transitions from > 1 to 1 are equally racy
and harmless (we copy even though there is no need).

  We handle this by spilling the whole thing to the stack and doing the

e876f6d052 Cap the percent CPU of individual threads at 100% to fix some of the
more obvious imprecision in the previous top changes.

Specifically, top uses a delta of clock_gettime() calls right after
invoking the kern.proc sysctl to fetch the process/thread list to
compute the time delta between the fetches.  However, the kern.proc
sysctl handler does not run in constant time.  It can spin on locks,
be preempted by an interrupt handler, etc.  As a result, the time
between the gathering of stats for individual processes or threads
between subsequent kern.proc handlers can vary.  If a "slow" kern.proc
run is followed by a "fast" kern.proc run, then the threads/processes
at the start of the "slow" run will have a longer time delta than the
threads/processes at the end.  If the clock_gettime() time delta is
not itself skewed by preemption, then the delta may be too short for
a given thread/process resulting in a higher percent CPU than actual.
However, there is no good way to calculate the exact amount of overage,
nor to know which threads to subtract the overage from.  Instead, just
punt and fix the definitely-wrong case of an individual thread having
more than 100% CPU.

02d3b38e0a Add the LD_LIBRARY_PATH_FDS environmental variable.
This variable allows the loading of shared libraries via directory descriptors
rather than via library paths.  If LD_LIBRARY_PATH_FDS=3:4:12, the directories
represented by file descriptors 3, 4 and 12 will searched for shared libraries
before the normal path-based mechanisms are used.  This allows us to execute
unprivileged binaries from within a Capsicum sandbox even if they require
shared libraries.
