suitable for holding object pointers (ptrint_t -> uintptr_t).
Added corresponding signed type (intptr_t). Changed/added
corresponding non-C9x types for function pointers to match. Don't
use nonstandard types to implement these types, and don't comment
on them in <machine/types.h>.
least unsuitable for holding an object pointer. This should have been
used to fix warnings about casts between pointers and ints on alphas.
Moved corresponding existing general typedef (fptrint_t) for function
pointers from the i386 <machine/profile.h> to a kernel-only typedef
in <machine/types.h>. Kludged libc/gmon/mcount.c so that it can
still see this typedef.
more cleanly integrated with stdio. This should be faster and cleaner
since it doesn't memcpy() the data into a seperate buffer. This lets
stdio allocate and manage the buffer and then hand it over to the user.

in 1.10 but backed out in 1.11; the FreeBSD code for %s
was earlier, prettier but buggier).
copy to bring these files into libc from libcompat. I will enable
them and kill off the libcompat versions on the main branch soon.

Return the result from getpagesize() if the p1003_1b.pagesize MIB
value is zero.

size we receive here should fit into the receive buffer. Unfortunately,
there's no 100% foolproof way to distinguish a ridiculously large record
size that a client actually meant to send us from a ridiculously large
record size that was sent as a spoof attempt.
The one value that we can positively identify as bogus is zero. A
zero-sized record makes absolutely no sense, and sending an endless
supply of zeroes will cause the server to loop forever trying to
fill its receive buffer.
Note that the changes made to readtcp() make it okay to revert this
sanity test since the deadlock case where a client can keep the server
occupied forever in the readtcp() select() loop can't happen anymore.
This solution is not ideal, but is relatively easy to implement. The
ideal solution would be to re-arrange the way dispatching is handled
so that the select() loop in readtcp() can be eliminated, but this is
difficult to implement. I do plan to implement the complete solution
eventually but in the meantime I don't want to leave the RPC library
totally vulnerable.
That you very much Sun, may I have another.
