  - add comments to syscalls.master and linux(32)_dummy about which linux
    kernel version introduced the sysctl (based upon a linux man-page)
  - add comments to syscalls.master regarding some names of sysctls which are
    different than the linux-names (based upon the linux unistd.h)
  - add some dummy sysctls
  - name an unimplemented sysctl

MFC r220028: linux compat: add non-dummy capget and capset system calls

The fourth argument of linux_clone is a pointer to the TLS.
Change clone syscall definition to match actual linux one.

MFC r218101:

Change linux futex syscall definition to match actual linux one.

Mark uname(), getdomainname() and setdomainname() with COMPAT_FREEBSD4.

2008-11-09T10:45:13+00:00

Looking at our source code history, it seems the uname(),
getdomainname() and setdomainname() system calls got deprecated
somewhere after FreeBSD 1.1, but they have never been phased out
properly. Because we don't have a COMPAT_FREEBSD1, just use
COMPAT_FREEBSD4.

Also fix the Linuxolator to build without the setdomainname() routine by
just making it call userland_sysctl on kern.domainname. Also replace the
setdomainname()'s implementation to use this approach, because we're
duplicating code with sysctl_domainname().

I wasn't able to keep these three routines working in our
COMPAT_FREEBSD32, because that would require yet another keyword for
syscalls.master (COMPAT4+NOPROTO). Because this routine is probably
unused already, this won't be a problem in practice. If it turns out to
be a problem, we'll just restore this functionality.

Implement robust futexes. Most of the code is modelled after

2008-05-13T20:01:27+00:00

what Linux does. This is because robust futexes are mostly
userspace thing which we cannot alter. Two syscalls maintain
pointer to userspace list and when process exits a routine
walks this list waking up processes sleeping on futexes
from that list.
