cap_ioctls_limit(2)

If a file descriptor is granted the capability right, the list of
allowed  commands can be selectively reduced (but never expanded)
with the system call.  The argument is an array of  commands  and
the  argument  specifies  the  number  of  elements in the array.
There can be up to elements in the array.  Including  an  element
that has been previously revoked will generate an error.  After a
successful  call only those listed in the array may be used.  The
list of allowed ioctl commands for a given file descriptor can be
obtained with the system call.  The  argument  points  at  memory
that  can hold up to values.  The function populates the provided
buffer with up to elements, but always returns the  total  number
of ioctl commands allowed for the given file descriptor.  The to‐
tal  number  of ioctls commands for the given file descriptor can
be obtained by passing argument and  as  the  argument.   If  all
ioctl  commands  are  allowed capability right is assigned to the
file descriptor and the system call was  never  called  for  this
file descriptor), the system call will return and will not modify
the buffer pointed to by the argument.  The function, if success‐
ful,  returns  the  total number of allowed ioctl commands or the
value if all ioctls commands are allowed.  On failure  the  value
is  returned and the global variable errno is set to indicate the
error.  succeeds unless: The argument is not a valid  descriptor.
The  argument  points  at  an  invalid  address.  The argument is
greater than would expand the list of allowed commands.  succeeds
unless: The argument is not a  valid  descriptor.   The  argument
points at invalid address.  Support for capabilities and capabil‐
ities  mode  was developed as part of the Project.  This function
was created by under sponsorship of the FreeBSD Foundation.
