| * lguest: use __PAGE_KERNEL instead of _PAGE_KERNELGlauber de Oliveira Costa2008-01-30
| | | | | | | | | | | | | | | | | | | | x86_64 don't expose the intermediate representation with one underline, _PAGE_KERNEL, just the double-underlined one.

| * lguest: per-vcpu lguest pgdir managementGlauber de Oliveira Costa2008-01-30
| | | | | | | | | | | | | | | | | | | | | | this patch makes the pgdir management per-vcpu. The pgdirs pool is still guest-wide (although it'll probably need to grow when we are really executing more vcpus), but the pgdidx index is gone, since it makes no sense anymore. Instead, we use a per-vcpu index. Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
| * lguest: make pending notifications per-vcpuGlauber de Oliveira Costa2008-01-30

| | | | | | | | | | | | | | | | | | | | lguest struct have room for some fields, namely, cr2, ts, esp1 and ss1, that are not really guest-wide, but rather, vcpu-wide.

| * lguest: per-vcpu lguest task managementGlauber de Oliveira Costa2008-01-30
| | | | | | | | | | | | | | | | | | | | lguest uses tasks to control its running behaviour (like sending breaks, controlling halted state, etc). In a per-vcpu environment, each vcpu will have its own underlying task. So this patch makes the infrastructure for that possible Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
| * lguest: replace lguest_arch with lg_cpu_arch.Glauber de Oliveira Costa2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | The fields found in lguest_arch are not really per-guest, but per-cpu (gdt, idt, etc). So this patch turns lguest_arch into lg_cpu_arch. It makes sense to have a per-guest per-arch struct, but this can be addressed later, when the need arrives.

| * lguest: make registers per-vcpuGlauber de Oliveira Costa2008-01-30
| | | | | | | | | | | | | | | | | | | | This is the most obvious per-vcpu field: registers.

| * lguest: make emulate_insn receive a vcpu struct.Glauber de Oliveira Costa2008-01-30
| | | | | | | | | | | | | | | | | | emulate_insn() needs to know about current eip, which will be, in the future, a per-vcpu thing.

| * lguest: map_switcher_in_guest() per-vcpuGlauber de Oliveira Costa2008-01-30
| | | | | | | | | | | | | | | | | | | | | | The switcher needs to be mapped per-vcpu, because different vcpus will potentially have different page tables (they don't have to, because threads will share the same). So our first step is the make the function receive a vcpu struct Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

| * lguest: make hypercalls use the vcpu structGlauber de Oliveira Costa2008-01-30
| | | | | | | | | | | | | | | | | | this patch changes do_hcall() and do_async_hcall() interfaces (and obviously their callers) to get a vcpu struct.

| * lguest: make write() operation smp awareGlauber de Oliveira Costa2008-01-30

| * lguest: per-cpu run guestGlauber de Oliveira Costa2008-01-30
| | | | | | | | | | | | | | | | | | This patch makes the run_guest() routine use the lg_cpu struct.

| * lguest: initialize vcpuGlauber de Oliveira Costa2008-01-30
| | | | | | | | | | | | | | | | | | | | this patch initializes the first vcpu in the initialize() routing, which is responsible for starting the process of putting the guest up. right now, as much of the fields are still not per-vcpu, it does not do much.

| * lguest: adapt launcher to per-cpunessGlauber de Oliveira Costa2008-01-30
| | | | | | | | | | | | | | | | | | | | This patch makes uses of pread() and pwrite() in lguest launcher to communicate the vcpu id to the lguest driver. The id is kept in a thread variable, which means we'll span in the future, vcpus as threads. But right now, only the infrastructure is out there.

| | | | | | | | | | | | | | | | | | | | | | | | Currently, lguest module can't be compiled without the PARAVIRT flag being on. This is a fake dependency, since the module itself shouldn't need any paravirt override. Reason for that is the reference to pv_info structure in initial loading tests.

| * | NetLabel: Introduce static network labels for unlabeled connectionsPaul Moore2008-01-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most trusted OSs, with the exception of Linux, have the ability to specify static security labels for unlabeled networks. This patch adds this ability to the NetLabel packet labeling framework. If the NetLabel subsystem is called to determine the security attributes of an incoming packet it first checks to see if any recognized NetLabel packet labeling protocols are in-use on the packet. If none can be found then the unlabled connection table is queried and based on the packets incoming interface and address it is matched with a security label as configured by the administrator using the netlabel_tools package. The matching security label is returned to the caller just as if the packet was explicitly labeled using a labeling protocol.

| * | SELinux: Allow NetLabel to directly cache SIDsPaul Moore2008-01-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the SELinux NetLabel "base SID" is always the netmsg initial SID we can do a big optimization - caching the SID and not just the MLS attributes. This not only saves a lot of per-packet memory allocations and copies but it has a nice side effect of removing a chunk of code.

| * | SELinux: Enable dynamic enable/disable of the network access checksPaul Moore2008-01-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces a mechanism for checking when labeled IPsec or SECMARK are in use by keeping introducing a configuration reference counter for each subsystem. In the case of labeled IPsec, whenever a labeled SA or SPD entry is created the labeled IPsec/XFRM reference count is increased and when the entry is removed it is decreased. In the case of SECMARK, when a SECMARK target is created the reference count is increased and later decreased when the target is removed. These reference counters allow SELinux to quickly determine if either of these subsystems are enabled. NetLabel already has a similar mechanism which provides the netlbl_enabled() function. This patch also renames the selinux_relabel_packet_permission() function to selinux_secmark_relabel_packet_permission() as the original name and description were misleading in that they referenced a single packet label which is not the case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rework the handling of network peer labels so that the different peer labeling subsystems work better together. This includes moving both subsystems to a single "peer" object class which involves not only changes to the permission checks but an improved method of consolidating multiple packet peer labels. As part of this work the inbound packet permission check code has been heavily modified to handle both the old and new behavior in as sane a fashion as possible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | functions This patch adds a SELinux IP address/node SID caching mechanism similar to the sel_netif_*() functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of storing the packet's network interface name store the ifindex. This allows us to defer the need to lookup the net_device structure until the audit record is generated meaning that in the majority of cases we never need to bother with this at all.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current SELinux netif code requires the caller have a valid net_device struct pointer to lookup network interface information. However, we don't always have a valid net_device pointer so convert the netif code to use the ifindex values we always have as part of the sk_buff. This patch also removes the default message SID from the network interface record, it is not being used and therefore is "dead code".

That is bad for two reasons: (1) it's doing (or trying to do) a scan of all devices when it should only be scanning those on the vio bus, and (2) devices_subsys was an internal symbol of the device system code which was never meant for external use and has now gone away, and thus the kernel fails to compile on pSeries.
