work present in FreeBSD 7.0 to refine the kernel privilege model:
- Introduce support for jail as a testing variable, in order to
confirm that privileges are properly restricted in the jail
environment.
- Restructure overall testing approach so that privilege and jail
conditions are set in the testing infrastructure before tests
are invoked, and done so in a custom-created process to isolate
the impact of tests from each other in a more consistent way.
- Tests now provide setup and cleanup hooks that occur before and
after the test runs.
- New privilege tests are now present for several audit
privileges, several credential management privileges, dmesg
buffer reading privilege, and netinet raw socket creation.
- Other existing tests are restructured and generally improved as
a result of better framework structure and jail as a variable.
For exampe, we now test that certain sysctls are writable only
outside jail, while others are writable within jail. On a
similar note, privileges relating to setting UFS file flags are
now better exercised, as with the right to chmod and utimes
files.

or replace (i.e., zdump) the environment after a call to setenv(), putenv()
or unsetenv() has been made, a few changes were made.
- getenv() will return the value from the new environ array.
- setenv() was split into two functions: __setenv() which is most of the
previous setenv() without checks on the name and setenv() which
contains the checks before calling __setenv().
- setenv(), putenv() and unsetenv() will unset all previous values and
call __setenv() on all entries in the new environ array which in turn
adds them to the end of the envVars array. Calling __setenv() instead
of setenv() is done to avoid the temporary replacement of the '=' in a
string with a NUL byte. Some strings may be read-only data.
Added more regression checks for clearing the environment array.
Replaced gettimeofday() with getrusage() in timing regression check for
better accuracy.
Fixed an off-by-one bug in __remove_putenv() in the use of memmove(). This
went unnoticed due to the allocation of double the number of environ
entries when building envVars.
Fixed a few spelling mistakes in the comments.

setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.
Convert all calls to POSIX from historic BSD API:
- unsetenv returns an int.
- putenv takes a char * instead of const char *.
- putenv no longer makes a copy of the input string.
- errno is set appropriately for POSIX. Exceptions involve bad environ
variable and internal initialization code. These both set errno to
EFAULT.
Several patches to base utilities to handle the POSIX changes from
Andrey Chernov's previous commit. A few I re-wrote to use setenv()
instead of putenv().
New regression module for tools/regression/environ to test these

and protocol-independent host mode multicast. The code is written to
accomodate IPv6, IGMPv3 and MLDv2 with only a little additional work.
This change only pertains to FreeBSD's use as a multicast end-station and
does not concern multicast routing; for an IGMPv3/MLDv2 router
implementation, consider the XORP project.
The work is based on Wilbert de Graaf's IGMPv3 code drop for FreeBSD 4.6,
which is available at: http://www.kloosterhof.com/wilbert/igmpv3.html
Summary
* IPv4 multicast socket processing is now moved out of ip_output.c
into a new module, in_mcast.c.
* The in_mcast.c module implements the IPv4 legacy any-source API in
terms of the protocol-independent source-specific API.
* Source filters are lazy allocated as the common case does not use them.
They are part of per inpcb state and are covered by the inpcb lock.
* struct ip_mreqn is now supported to allow applications to specify
multicast joins by interface index in the legacy IPv4 any-source API.
* In UDP, an incoming multicast datagram only requires that the source
port matches the 4-tuple if the socket was already bound by source port.
An unbound socket SHOULD be able to receive multicasts sent from an
ephemeral source port.
* The UDP socket multicast filter mode defaults to exclusive, that is,
sources present in the per-socket list will be blocked from delivery.
* The RFC 3678 userland functions have been added to libc: setsourcefilter,
getsourcefilter, setipv4sourcefilter, getipv4sourcefilter.
* Definitions for IGMPv3 are merged but not yet used.
* struct sockaddr_storage is now referenced from <netinet/in.h>. It
is therefore defined there if not already declared in the same way
as for the C99 types.
* The RFC 1724 hack (specify 0.0.0.0/8 addresses to IP_MULTICAST_IF
which are then interpreted as interface indexes) is now deprecated.
* A patch for the Rhyolite.com routed in the FreeBSD base system
is available in the -net archives. This only affects individuals
running RIPv1 or RIPv2 via point-to-point and/or unnumbered interfaces.
* Make IPv6 detach path similar to IPv4's in code flow; functionally same.
* Bump __FreeBSD_version to 700048; see UPDATING.

desired in the most of practical cases, e.g.: delete lines 5-9

Keep the previous semantics of -i under a new option, -I, which
uses a single continuous address space covering all files to edit
in-place -- they are too cool to just drop them.
Add regression tests for -i and -I.
