for multicast packets. Parameters for the interface, packet size,
number of packets, and interpacket gap may be given on the command line.
The sink records how many packets were missed, and at what time each
packet arrived.
Solaris and AIX.
fcntl(fd, F_DUP2FD, arg) and dup2(fd, arg) are functionnaly equivalent.
Document it.
Add some regression tests (identical to the dup2(2) regression tests).

Use the correct value of errno. Although the errno value passed into
printf() follows the *env() call, it is not guaranteed to be the errno
from that call. When I wrote the regression tester, the environment I
used did pass the errno from the call. Consolidate the print for the
return code and errno into a function in the process of fixing this.

Note: it may be a good idea to deduce obsolete usr/lib32/ files from
obsolete lib/ and usr/lib/ files.

various open flags and then tests various operations to make sure that
they are properly constrained by open flags. Various I/O mechansms
are tried, including aio if compiled into the kernel or loaded as a
module. There's more to be done here but it's a useful start, running
about 220 individual tests.
This is in support of FreeBSD-SA-08:03.sendfile.
the semantics of pthread_mutex_islocked_np() to return true if and only if
the mutex is held by the current thread.
Obviously, change the regression test to match.

- Process (a) is blocked in read on a socket waiting on data.
- Process (b) is blocked in shutdown() on a socket waiting on (a).
- Process (c) delivers a signal to (b) interrupting its wait.
When the signal is delivered, the kernel panics as sblock() fails in
sorflush(). Even if it didn't panic, shutdown() would block potentially
indefinitely waiting for recv() to succeeded. Fixes to follow.

mostly just test corner cases rather than accuracy. Some of the
tests don't pass right now if you compile libm at -O2 due to gcc
constant-folding some things that it shouldn't. I'll fix that
shortly.
* Explain why 32768 entries is usually not enough
* Increase the scaling ratio to 10 to deal with 32-bit overflows that
can occur in calculating the canvas offsets
disk image. In some cases this can be a significant speed-up, if
most of the image can be kept in RAM while being populated.
On the 2GB image I'm currently working with, the build time,
excluding buildworld/buildkernel, goes from ~17 minutes to ~6
minutes.
This is not enabled by default, as it might have the opposite effect
on low-memory systems.
- During the generation of the image file be a bit more verbose in the
log file so it is possible to see what's being done.
- Add a NANO_DISKIMGDIR variable which makes it possibly to place the
final images somewhere other than ${MAKEOBJDIRPREFIX}. The default
value for NANO_DISKIMGDIR is $MAKEOBJDIRPREFIX.
Go for it: phk
Due to a typo, setting NANO_DATASIZE=-1 resulted in the data slice
being the same size as entire image instead of the size of the
remaining space on the image.
- Fix detection of overcommit of the slices.
This fix mainly result in a nicer error than when newfs etc. tries to
write beyond the end of the disk image.
