* xen: add /dev/xen/evtchn driverIan Campbell2009-03-30
| | | | | | | | | | This driver is used by application which wish to receive notifications from the hypervisor or other guests via Xen's event channel mechanism. In particular it is used by the xenstore daemon in domain 0. Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

* x86-64: non-paravirt systems always has PSE and PGEJeremy Fitzhardinge2009-03-30
| | | | | | | | | A paravirtualized system may not have PSE or PGE available to guests, so they are not required features. However, without paravirt we can assume that any x86-64 implementation will have them available. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

* xen: mask XSAVE from cpuidJeremy Fitzhardinge2009-03-30
| | | | | | | | | | | | | | Xen leaves XSAVE set in cpuid, but doesn't allow cr4.OSXSAVE to be set. This confuses the kernel and it ends up crashing on an xsetbv instruction. At boot time, try to set cr4.OSXSAVE, and mask XSAVE out of cpuid it we can't. This will produce a spurious error from Xen, but allows us to support XSAVE if/when Xen does. This also factors out the cpuid mask decisions to boot time. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

* xen: make xen_load_gdt simplerJeremy Fitzhardinge2009-03-30
| | | | | | | | | Remove use of multicall machinery which is unused (gdt loading is never performance critical).

* mm: allow preemption in apply_to_pte_rangeJeremy Fitzhardinge2009-03-30
| | | | | | | | | | | | Impact: allow preemption in apply_to_pte_range updates to init_mm Preemption is now allowed for lazy mmu mode, so don't disable it for the inner loop of apply_to_pte_range. This only applies when doing updates to init_mm; user pagetables are still modified under the pte lock, so preemption is disabled anyway.

* x86/paravirt: finish change from lazy cpu to context switch start/endJeremy Fitzhardinge2009-03-30
| | | | | | | | | | | | Impact: fix lazy context switch API Pass the previous and next tasks into the context switch start end calls, so that the called functions can properly access the task state (esp in end_context_switch, in which the next task is not yet completely current).

* x86/paravirt: flush pending mmu updates on context switchJeremy Fitzhardinge2009-03-30
| | | | | | | | | | | | | | | Impact: allow preemption during lazy mmu updates If we're in lazy mmu mode when context switching, leave lazy mmu mode, but remember the task's state in TIF_LAZY_MMU_UPDATES. When we resume the task, check this flag and re-enter lazy mmu mode if its set. This sets things up for allowing lazy mmu mode while preemptible, though that won't actually be active until the next change.

* x86/pvops: replace arch_enter_lazy_cpu_mode with arch_start_context_switchJeremy Fitzhardinge2009-03-30
| | | | | | | | | | | Impact: simplification, prepare for later changes Make lazy cpu mode more specific to context switching, so that it makes sense to do more context-switch specific things in the callbacks.

* x86/paravirt: remove lazy mode in interruptsJeremy Fitzhardinge2009-03-30
| | | | | | | | | | | | | | Impact: simplification, robustness Make paravirt_lazy_mode() always return PARAVIRT_LAZY_NONE when in an interrupt. This prevents interrupt code from accidentally inheriting an outer lazy state, and instead does everything synchronously. Outer batched operations are left deferred.

* mm: disable preemption in apply_to_pte_rangeJeremy Fitzhardinge2009-03-30
| | | | | | | | | | | Impact: bugfix Lazy mmu mode needs preemption disabled, so if we're apply to init_mm (which doesn't require any pte locks), then explicitly disable preemption. (Do it unconditionally after checking we've successfully done the allocation to simplify the error handling.) Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

The mmap_sem is no longer held, so get_user() should be adequate. This patch greatly simplifies the logic and improves legibility. Build and boot tested on a 4 way Intel x86_64 workstation.

The mmap_sem is no longer held outside of the futex_handle_fault() routine, yet numerous comments refer to it. The fshared argument is no an integer. I left some of these comments along as they are simply removed in future patches. Some of the commentary refering to futexes by virtual page mappings was not very clear, and completely accurate (as for shared futexes both the page and the offset are used to determine the key). For the purposes of the function description, just referring to "the futex" seems sufficient. With hashed futexes we now access the page after the hash-bucket is locked, and not only after it is enqueued.

| * | | | | netlabel: Cleanup the Smack/NetLabel code to fix incoming TCP connectionsPaul Moore2009-03-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up a lot of the Smack network access control code. The largest changes are to fix the labeling of incoming TCP connections in a manner similar to the recent SELinux changes which use the security_inet_conn_request() hook to label the request_sock and let the label move to the child socket via the normal network stack mechanisms. In addition to the incoming TCP connection fixes this patch also removes the smk_labled field from the socket_smack struct as the minor optimization advantage was outweighed by the difficulty in maintaining it's proper state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The socket_post_accept() hook is not currently used by any in-tree modules and its existence continues to cause problems by confusing people about what can be safely accomplished using this hook. If a legitimate need for this hook arises in the future it can always be reintroduced. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: James Morris <jmorris@namei.org>
