* DESCRIPTION
|
|
* check rmdir() fails with EPERM or EACCES
|
|
*
|
|
* 1. Create a directory tstdir1 and set the sticky bit, then
|
|
* create directory tstdir2 under tstdir1. Call rmdir(),
|
|
* set to be user nobody. Pass tstdir2 to rmdir(2), verify
|
|
* the return value is not 0 and the errno is EPERM or EACCES.
|
|
*
|
|
* 2. Create a directory tstdir1 and doesn't give execute/search
|
|
* permission to nobody, then create directory tstdir2 under
|
|
* tstdir1. Call rmdir(), set to be user nobody. Pass
|
|
* tstdir2 to rmdir(2), verify the return value is not 0 and
|
|
* the errno is EACCES.
