Tor created a while ago, removes the raw I/O piece (that has cache coherency
problems), and adds a buffer cache / VM freeing piece.
Essentially this patch causes O_DIRECT I/O to not be left in the cache, but
does not prevent it from going through the cache, hence the 80%. For
the last 20% we need a method by which the I/O can be issued directly to
buffer supplied by the user process and bypass the buffer cache entirely,
but still maintain cache coherency.
I also have the code working under -stable but the changes made to sys/file.h
may not be MFCable, so an MFC is not on the table yet.

accidentally clobber the server address if a stray packet arrived
at the client port. This would result in any further retransmits
going to the wrong address.
For now, fix this by not saving the source address of the reply; this
matches the pre-tirpc behaviour.

terminates the string in all cases, based on code from netstat(1).
The path in a sockaddr_un is terminated either by a '\0', or by
the end of the sockaddr as defined by sun_len.
Previously, the code could write the "safety" '\0' beyond the end
of the sockaddr (sockaddr_un's need only be large enough to store
sun_len bytes), and writing into the the supplied sockaddr is bad
anyway.
longer includes machine/elf.h.
* consumers of elf.h now use the minimalist elf header possible.
This change is motivated by Binutils 2.11.0 and too much clashing over
our base elf headers and the Binutils elf headers.
address" string to a netbuf/sockaddr "transport address". In the
case of an AF_LOCAL address, it was missing the code to actually
point the netbuf at the newly allocated sockaddr_un, so the caller
ended up with a netbuf containing junk.

required by POSIX.1e. This maintains the current 'struct acl'
in the kernel while providing the generic external acl_t
interface required to complete the ACL editing library.
o Add the acl_get_entry() function.
o Convert the existing ACL utilities, getfacl and setfacl, to
fully make use of the ACL editing library.

arguments where the format string is obtained from user data, or
otherwise difficult to verify statically.
Example usage:
printf(fmtcheck(user_format, standard_format), arg1, arg2);
checks the format string user_format for consistency (same number/order/
type of format operators) with standard_format. If they differ,
standard_format is used instead to avoid potential crashes or security
violations.
