The core kernel part is patch file utimes.2008.4.diff from pluknet@FreeBSD.org. I updated the code for API changes, added the manual page and added compatibility code for old kernels. There is also audit and Capsicum support. A new UTIME_* constant might allow setting birthtimes in future.

|
.Nm Capability rights
|
|
.Nd Capsicum capability rights for file descriptors
|
|
.Sh DESCRIPTION
|
|
When a file descriptor is created by a function such as
|
|
.Xr accept 2 ,
|
|
.Xr accept4 2 ,
|
|
.Xr fhopen 2 ,
|
|
.Xr kqueue 2 ,
|
|
.Xr mq_open 2 ,
|
|
.Xr open 2 ,
|
|
.Xr openat 2 ,
|
|
.Xr pdfork 2 ,
|
|
.Xr pipe 2 ,
|
|
.Xr shm_open 2 ,
|
|
.Xr socket 2
|
|
or
|
|
.Xr socketpair 2 ,
|
|
it is assigned all capability rights.
|
|
Those rights can be reduced (but never expanded) by using the
|
|
.Xr cap_rights_limit 2 ,
|
|
.Xr cap_fcntls_limit 2 and
|
|
.Xr cap_ioctls_limit 2
|
|
system calls.
|
|
Once capability rights are reduced, operations on the file descriptor will be
|
|
limited to those permitted by rights.
|
|
.Pp
|
|
The complete list of capability rights is provided below.
|
|
The
|
|
.Vt cap_rights_t
