sys/kern kern_environment.c
Log:
Fixed some longstanding bugs in _getenv_static():
- 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.
