continue. A thread trying to clean out the extant layer vnode needs to
acquire the shared lock (i.e. the lower vnode's lock), which our caller
already holds. To allow the cleaning to succeed the current thread must make
progress. So, for a brief time more than one vnode in a layered file system
may refer to a single vnode in the lower file system.
enabling it. Explicitly initialise LINT0 as ExtInt and LINT1 as NMI,
the platform default. Mask the NMIs on the application processors and
mask the ExtInt if a IOAPIC was found.
With this patch, "disable ioapic" is supposed to work and it will allow
enabling the local APIC on all systems that have one to gain e.g. the
better clock interrupt.
(domU only). PAE support is enabled by 'options PAE', see the new XEN3PAE_DOMU
and INSTALL_XEN3PAE_DOMU kernel config files.
See the comments in arch/i386/include/{pte.h,pmap.h} to see how it works.
In short, we still handle it as a 2-level MMU, with the second level page
directory being 4 pages in size. pmap switching is done by switching the
L2 pages in the L3 entries, instead of loading %cr3. This is almost required
by Xen, which handle the last L2 page (the one mapping 0xc0000000 - 0xffffffff)
in a very special way. But this approach should also work for native PAE
support if ever supported (in fact, the pmap should almost suport native
PAE, what's missing is bootstrap code in locore.S).
- Add a KAUTH_PROCESS_SCHEDULER action, to handle scheduler related
requests, and add specific requests for set/get scheduler policy and
set/get scheduler parameters.
- Add a KAUTH_PROCESS_KEVENT_FILTER action, to handle kevent(2) related
requests.
- Add a KAUTH_DEVICE_TTY_STI action to handle requests to TIOCSTI.
- Add requests for the KAUTH_PROCESS_CANSEE action, indicating what
process information is being looked at (entry itself, args, env,
open files).
- Add requests for the KAUTH_PROCESS_RLIMIT action indicating set/get.
- Add requests for the KAUTH_PROCESS_CORENAME action indicating set/get.
- Make bsd44 secmodel code handle the newly added rqeuests appropriately.
All of the above make it possible to issue finer-grained kauth(9) calls in
many places, removing some KAUTH_GENERIC_ISSUSER requests.
- Remove the "CAN" from KAUTH_PROCESS_CAN{KTRACE,PROCFS,PTRACE,SIGNAL}.
Discussed with christos@ and yamt@.
1 Extract subroutine if_dl_create() from if_alloc_sadl().
if_dl_create() allocates a link-layer ifaddr.
2 Extract subroutine ifioctl_common() from ifioctl(). ifioctl_common()
will be the basis for an ifnet "superclass" whose functions
drivers may inherit. Very simple drivers may set ifnet->if_ioctl
= ifioctl_common. More sophisticated drivers will set ifnet->if_ioctl
= driver_ioctl. driver_ioctl() will call ifioctl_common() to
re-use the common code.
- Entries should end with a dot.
- Entries should start with a capital letter.
- Entries should not have extra whitespaces.
PLEASE FOLLOW THE STYLE IN FUTURE COMMITS TO THAT FILE.
