* Significantly reduce the memory leak as noted in BUGS section forSean Farley2007-07-041-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 functions. It also can be used to test the performance. Bump __FreeBSD_version to 700050 due to API change.

| | | | | | | | | | | | | | | | | | | | | | | potentially dangerous environment variables all together. It should be noted that the run-time linker will not honnor these environment variables if the process is tainted currently. However, once a child of the tainted process calls setuid(2), it's status as being tainted (as defined by issetugid(2)) will be removed. This could be problematic because subsequent activations of the run-time linker could honnor these dangerous variables. This is more of an anti foot-shot mechanism, there is nothing I am aware of in base that does this, however there may be third party utilities which do, and there is no real negative impact of clearing these environment variables.

| | | | | | | | | | | | | | | | | The support for RFC 2640 (UTF8) is optional and rudimentary. The server just advertises its capability to handle UTF-8 file names and relies on its own 8-bit cleanness, as well as on the backward compatibility of UTF-8 with ASCII. So uploaded files will have UTF-8 names, but the initial server contents should be prepared in UTF-8 by hand, no on-the-fly conversion of file names will be done.
