ff16079e49 upas/fs: speedup mtree and henter()
move digest pointer into Mtree structrue and embed it into Idx struct
(which is embedded in Message) to avoid one level of indirection
during mtreecmp().

get rid of mtreeisdup(). instead we have mtreeadd() return the old
message in case of a collision. this avoids double lookup.

increase the hash table size for henter() and make it a prime.

0ee738ef8c vgai81x: use vmap() for uncached access to cursor data instead of manipulating kernel page table
on 386, the kernel memory region is mapped using huge 4MB pages
(when supported by the cpu). so the uncached pte manipulation
does not work to map the cursor data with uncached attribute.

instead, we allocate a memory page using newpage() and map
it globally using vmap(), which maps it uncached.

490c3d87cb usbxhci: fix endpoint stall recovery, handle Ep.clrhalt flag
after issuing CR_RESETEP command, we have to invalidate
the endpoints output context buffer so that the halted/error
status reflects the new state. not doing so resulted in
the halted state to be stuck and we continued issuing
endpoint reset commands when we where already recovered.

handle the devusb Ep.clrhalt flag from devusb that userspace
uses to force a endpoint reset on the next transaction.

71a1d11a81 cmd/ip/*: chown the network connection after authentication
for servers that handle incoming network connections and authentication,
change the owner of the network connection file to the authenticated user
after successfull authentication.

note that we set the permissions as well to 0660 because old devip used
to unconditionally set the bits.

5993760e14 devip: fix permission checking
permission checking had the "other" and "owner" bits swapped plus incoming
connections where always owned by "network" instead of the owner of
the listening connection. also, ipwstat() was not effective as the uid
strings where not parsed.

this fixes the permission checks for data/ctl/err file and makes incoming
connections inherit the owner from the listening connection.

we also allow ipwstat() to change ownership to the commonuser() or anyone
if we are eve.

we might have to add additional restrictions for none at a later point...

b56909157f bootrc: unmount devip *before* starting factotum
we want devip to get reattached after hostowner has been written. factotum
already handles this with a private authdial() routine that mounts devip
when it is not present. so we detach devmnt before starting factotum,
and attach once factotum finishes.

5b7d8e1f6f bootrc: remount devip after /dev/hostowner has been written by factotum
devip remembers the attach uname so after we set hostowner we
remount devip so future connections have the right owner.

12fa017f3f devproc: fix fishy locking in proctext(), check proc validity, static functions
the locking in proctext() is wrong. we have to acquire Proc.seglock
when reading segments from Proc.seg[] as segments do not
have a private freelist and can therefore be reused for other
data structures.

once we have Proc.seglock acquired, check that the process pid
is still valid so we wont accidentally read some other processes
segments. (for both proctext() and procctlmemio()). this also
should give better error message to distinguish the case when
the process did segdetach() the segment in question before we
could acquire Proc.seglock.

declare private functions as static.

acab8881bc bcm64: enter page tables in mmutop *AFTER* switching asid in mmuswitch()
there was a small window between modifying mmutop and switching the
asid where the core could bring in the new entries under the old asid
into the tlb due to speculation / prefetching.

this change moves the entering of the page tables into mmutop after
setttbr() to prevent this scenario.

due to us switching to the resereved asid 0 on procsave()->putasid(),
the only asid that could have potentially been poisoned would be asid 0
which does not have any user mappings. so this did not show any noticable
effect.

ca2f1c07f2 acid/kernel: for stacktraces, try to use context from error stack when process is not sleeping
when a process state has not been saved (Proc.mach != nil)
then the contents of Proc.sched should be considered invalid.

to approximate a stacktrace in this case, we use the error
stack and get a stacktrace from the last waserror() call.

71939a82cc Allow address expressions in ?c after int casts.
This fixes ocaml on non-x86 architectures, where we have code
that looks like:

	#define Fl_head ((uintptr_t)(&sentinel.first_field))

Without this change, we get an error about a non-constant
initializer. This change takes the checks for pointers and
makes them apply to all expressions. It also makes the checks
stricter, preventing the following from compiling to junk:

	int x;
	int y = 42;
	int *p = &x + y

766a641d25 cc: fix void cast crash
the following code reproduces the crash:

void
foo(void)
{
}

void
main(int argc, char **argv)
{
	(void)(1 ? (void)0 : foo());
}

the problem is that side() gives a false positive on the OCOND
with later constant folding eleminating the acutal side effect
and OCAST ending up with two nested OCATS with the nested one
being zapped (type == T).

6aa7ebcf49 kernel: make exec clear errstr, stop side-channels and truncate on utf8 boundary
make exec() clear the per process error string
to avoid spurious errors and confusion.

the errstr() syscall used to always swap the
maximum buffer size with memmove(), which is
problematic as this gives access to the garbage
beyond the NUL byte. worse, newproc(), werrstr()
and rerrstr() only clear the first byte of the
input buffer. so random stack rubble could be
leaked across processes.

we change the errstr() syscall to not copy
beyond the NUL byte.

the manpage also documents that errstr() should
truncate on a utf8 boundary so we use utfecpy()
to ensure proper NUL termination.
