call its d_ioctl function. This should fix an undefined reference to
`clockctlioctl' when you build a kernel that has COMPAT_50 but does not
have pseudo-device clockctl.
When time_t was changed from 32 to 64 bits, this ioctl's number
was changed from _IOWR('C', 0x4, struct clockctl_ntp_adjtime)
to _IOWR('C', 0x8, struct clockctl_ntp_adjtime), but the data
structure did not change, so all the compat code has to do is
change the number and try again.
- Introduce MSG_NBIO so that we can turn non blocking i/o on a per call basis
- Use MSG_NBIO to fix the XXX: multi-threaded issues on the fifo sockets.
- Don't set SO_CANTRCVMORE, if we were interrupted (perhaps do it for all
errors?).
ioctl commands.
Tested with "rndctl -ls" using an old 32-bit version of rndctl(8)
(built for NetBSD-5.99.56/i386) and a new 64-bit kernel
(NetBSD-5.99.59/amd64).
it should be:
- stuff for the proplib interface goes in <quota/quotaprop.h>
- stuff for userlevel only goes in <quota/quota.h>
- stuff shared between user and kernel goes in <sys/quota.h>
Note that <quota/quota.h> and <quota/quotaprop.h> are expected to be
moved or removed later on... one thing at a time.
Update include directives in other files as needed.
no longer get it via sys/ucred.h and don't already include it
explicitly. These should in turn be removed when it can be confirmed
that it's safe to do so. (Because sys/param.h is full of things that
are often tested with #if, it's not in general safe to remove it
without checking, as such tests fail silently if the symbol goes
missing.)
returned to userland by read(2) also needs to be converted.
For this, the bpf descriptor is flagged as compat32 (or not) in the
open and ioctl functions (where the user process's pid is also updated
in the descriptor). When the bpf buffer is filled in, the 32bits or native
header is used depending on the information stored in the descriptor.
This won't work if a 64bit binary does the open and ioctls, and then
exec a 32bit program which will do the read. But this is very
unlikely to happen in real life ...
Tested on i386 and loongson; with these changes my loongson can run
dhclient and tcpdump with a n32 userland.
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.
