be out of sync in a very inconvenient way.
Changes include:
* Some whitespace fixes, also move the pseudo_variables definition
into pseudo_util.c since it's not used anywhere else.
* Further improvements in the fork() support:
We now recognize both positive and negative forms of PSEUDO_DISABLED,
so we can distinguish between "it was removed from the environment
by env -i" (restore the old value) and "it was intentionally turned
off" (the new value wins).
* clone(2) support. This is a little primitive, and programs might still
fail horribly due to clone's semantics, but at least it's there and
passes easy test cases.
Plus a big patch from Mark Hatle:
Cleanup fork/clone and PSEUDO_DISABLED
guts/fork.c:
* cleanup function and make it more robust
* be sure to call pseudo_setupenv prior to pseudo_client_reset
to match exec behavior
pseudo_wrappers.c:
* fix mismatched type in execl_to_v call via typecast
* Simplify fork call via single call to wrap_fork()
* be sure to save pseudo_disabled
* be sure to call pseudo_setupenv prior to pseudo_client_reset
to match exec behavior
tests:
* Add a test of whether pseudo can be disabled/enabled on a fork.

The PSEUDO_DEBUG_FILE feature is enhanced, and is now also used by the
pseudo server.

Address a couple of compiler warnings, add a couple of signals to the
list of caught signals, etcetera.

It is possible for the database to get out of sync with the
filesystem. Detecting this after the fact can be hard. Provide a
hook for requesting a check.
Also merge in some LD_LIBRARY_PATH fixes.

This is a first pass at handling password/group calls, allowing
the use of custom password/group files. In particular, when
chroot()ed to a particular directory, pseudo picks files in
that directory by default, to improve support for the typical
use case where pseudo uses chroot() only to jump into a virtual
target filesystem.
|
|
Add chroot() and a large number of things needed to make it work.
The list of intercepted calls is large but not exhaustive.
|
|
Add the -h (help) option to pseudo, and document -h for both
pseudo and pseudolog.
