The errno message display added in r222292 did not take attempting to
cd to a non-directory or something that cannot be stat()ed into account.

have been translated to $'...' escape sequences as understood by our sh(1).

- While here, make this compile and work on non-i386:
- Use CMSG_SPACE(), CMSG_LEN(), and CMSG_FIRSTHDR() instead of ignoring
padding between 'struct cmsghdr' and control message payloads.
- Don't initialize the control message before calling recvmsg().
Instead, check that we get a valid control message on return from
recvmsg().
- Use errx() instead of err() for some errors that don't report failures
that set errno.

The "domain-search" option (option 119) allows a DHCP server to publish
a list of implicit domain suffixes used during name lookup. This option
is described in RFC 3397.
For instance, if the domain-search option says:
".example.org .example.com"
and one wants to resolve "foobar", the resolver will try:
1. "foobar.example.org"
2. "foobar.example.com"
The file /etc/resolv.conf is updated with a "search" directive if the
DHCP server provides "domain-search".
A regression test suite is included in this patch under
tools/regression/sbin/dhclient.

- plus: execute "+command" when run with -jX -n
- ellipsis: ellipsis ("...") from variable
- empty: empty command (from variable)
Currently make(1) fails all three tests:
- plus: segmentation fault due to incorrect command list handling
- ellipsis: works in compat mode but fails in job (-jX) mode
- empty:
- compat mode: prints error message
- job mode: works but prints empty string
POSIX says the exit status of a for loop without any items shall be 0. There
are no exceptions if the exit status of the previous command was not 0 or if
the item list contains a command substitution with non-zero exit status.
Distinguish IPv4 and IPv6 addresses and optional port numbers in
user space to set the option for the correct protocol family.
Add support in the kernel for carrying the new IPv6 destination
address and port.
Add support to TCP and UDP for IPv6 and fix UDP IPv4 to not change
the address in the IP header.
Add support for IPv6 forwarding to a non-local destination.
Add a regession test uitilizing VIMAGE to check all 20 possible
combinations I could think of.

Ensure that process descriptors work as expected. We should be able to:
- pdfork(), like regular fork(), but producing a process descriptor
- pdgetpid() to convert a PD into a PID
- pdkill() to send signals to a process identified by a PD

When calling poll(2) on a capability, unwrap first and then poll the

This commit adds regression testing for openat(), fstatat(), etc. with
capability scoping ("strict relative" lookup), which applies:
- in capability mode
- when performing any *at() lookup relative to a capability
These tests will fail until the *at() code is committed; on my local
instance, with the *at() changes, they all pass.

As per kib's suggestion, we also change test_count from a size_t to an int;
its value at the moment is 4, and we only expect it to go up to 7.

kernel for FreeBSD 9.0:
Add a new capability mask argument to fget(9) and friends, allowing system
call code to declare what capabilities are required when an integer file
descriptor is converted into an in-kernel struct file *. With options
CAPABILITIES compiled into the kernel, this enforces capability
protection; without, this change is effectively a no-op.
Some cases require special handling, such as mmap(2), which must preserve
information about the maximum rights at the time of mapping in the memory
map so that they can later be enforced in mprotect(2) -- this is done by
narrowing the rights in the existing max_protection field used for similar
purposes with file permissions.
In namei(9), we assert that the code is not reached from within capability
mode, as we're not yet ready to enforce namespace capabilities there.
This will follow in a later commit.
Update two capability names: CAP_EVENT and CAP_KEVENT become
CAP_POST_KEVENT and CAP_POLL_KEVENT to more accurately indicate what they
represent.

Even if we have CAP_FCHFLAGS, fchflags(2) fails on NFS. This is normal
and expected, so don't fail the test because of it.
Note that, whether or not we are on NFS, fchflags(2) should always fail
with ENOTCAPABLE if we are using a capability that does not have the
CAP_FCHFLAGS right.

Formerly, in this case an error was returned but the pid was also returned
to the application, requiring the application to use unspecified behaviour
(the returned pid in error situations) to avoid zombies.
Now, reap the zombie and do not return the pid.

Rather than using err() if either of two failure conditions
fires (which can produce spurious error messages), just use
errx() if the one condition that really matters fires.
In practice, this single test is enough to detect the failure
mode we're looking for (kqueue being inherited across fork).
Approved by: mentor (rwatson), re (Capsicum blanket)

Modify the existing unit test (from libkqueue) which already exercises process events via
fork() and kill(). Now, the child process simply checks that the 'kqfd' descriptor is invalid.
Some minor modifications were required to make err() work correctly. It seems that this test
was imported using the output of a configure script, but config.h was not included in key
places, nor was its syntax correct (need '#define HAVE_FOO 1' rather than '#define HAVE_FOO').
Finally, change main() to run the "proc" suite by default, but widened the '#if TODO' in
proc.c to include the non-functioning test event_trigger().
