r258148:
Add a note that this file is compiled as part of the kernel and libc.
Requested by: kib
r258149:
Change cap_rights_merge(3) and cap_rights_remove(3) to return pointer
to the destination cap_rights_t structure.
This already matches manual page.
r258150:
Sync return value with actual implementation.
r258151:
Style.
r258152:
Precisely document capability rights here too (they are already documented
in rights(4)).
r258153:
The CAP_LINKAT, CAP_MKDIRAT, CAP_MKFIFOAT, CAP_MKNODAT, CAP_RENAMEAT,
CAP_SYMLINKAT and CAP_UNLINKAT capability rights make no sense without
the CAP_LOOKUP right, so include this rights.
r258154:
- Move CAP_EXTATTR_* and CAP_ACL_* rights to index 1 to have more room
in index 0 for the future.
- Move CAP_BINDAT and CAP_CONNECTAT rights to index 0 so we can include
CAP_LOOKUP right in them.
- Shuffle the bits around so there are no gaps. This is last chance to do
that as all moved rights are not used yet.
r258181:
Replace CAP_POLL_EVENT and CAP_POST_EVENT capability rights (which I had
a very hard time to fully understand) with much more intuitive rights:
CAP_EVENT - when set on descriptor, the descriptor can be monitored
with syscalls like select(2), poll(2), kevent(2).
CAP_KQUEUE_EVENT - When set on a kqueue descriptor, the kevent(2)
syscall can be called on this kqueue to with the eventlist
argument set to non-NULL value; in other words the given
kqueue descriptor can be used to monitor other descriptors.
CAP_KQUEUE_CHANGE - When set on a kqueue descriptor, the kevent(2)
syscall can be called on this kqueue to with the changelist
argument set to non-NULL value; in other words it allows to
modify events monitored with the given kqueue descriptor.
Add alias CAP_KQUEUE, which allows for both CAP_KQUEUE_EVENT and
CAP_KQUEUE_CHANGE.
Add backward compatibility define CAP_POLL_EVENT which is equal to CAP_EVENT.
r258182:
Correct right names.
