* Fixed some longstanding bugs in _getenv_static():Bruce Evans2002-04-251-3/+4
| | | | | | | | | | | | | | | | - malformed environment strings (ones without an '=') were not rejected. There shouldn't be any of these, but when the static environment is empty it always begins with one of these; this one should be considered as the terminator after the end of the environment, but it isn't. - the comparison of the name being looked up with the name in the environment was fuzzy -- only the characters up to the length of the latter were compared, so _getenv_static("foobar") matched "foo=..." in the environment and everything matched "" in the empty environment.

* Rework the kernel environment subsystem. We now convert the staticMaxime Henrion2002-04-171-59/+308
| | | | | | | | | | | | | | | | | | | | environment needed at boot time to a dynamic subsystem when VM is up. The dynamic kernel environment is protected by an sx lock. This adds some new functions to manipulate the kernel environment : freeenv(), setenv(), unsetenv() and testenv(). freeenv() has to be called after every getenv() when you have finished using the string. testenv() only tests if an environment variable is present, and doesn't require a freeenv() call. setenv() and unsetenv() are self explanatory. The kenv(2) syscall exports these new functionalities to userland, mainly for kenv(1). Reviewed by: peter Notes: svn path=/head/; revision=94936
