* [IPSEC]: Add support for combined mode algorithmsHerbert Xu2008-01-31
| | | | | | | | | | | | | | | | This patch adds support for combined mode algorithms with GCM being the first algorithm supported. Combined mode algorithms can be added through the xfrm_user interface using the new algorithm payload type XFRMA_ALG_AEAD. Each algorithms is identified by its name and the ICV length. For the purposes of matching algorithms in xfrm_tmpl structures, combined mode algorithms occupy the same name space as encryption algorithms. This is in line with how they are negotiated using IKE.

* Move usbnet.h and rndis_host.h to include/linux/usbJussi Kivilinna2008-01-31
| | | | | | | | | | | Move headers usbnet.h and rndis_host.h to include/linux/usb and fix includes for drivers/net/usb modules. Headers are moved because rndis_wlan will be outside drivers/net/usb in drivers/net/wireless and yet need these headers.

* rfkill: add the WiMAX radio typeIñaky Pérez-González2008-01-31
| | | | | | | | | | | | | | | | Teach rfkill about wimax radios. Had to define a KEY_WIMAX as a 'key for disabling only wimax radios', as other radio technologies have. This makes sense as hardware has specific keys for disabling specific radios. The RFKILL enabling part is, otherwise, a copy and paste of any other radio technology.

| * NFS: Switch from intr mount option to TASK_KILLABLEMatthew Wilcox2007-12-06
| | | | | | | | | | | | | | | | | | By using the TASK_KILLABLE infrastructure, we can get rid of the 'intr' mount option.

That, in turn, drastically simplifies the code, and drops down line count. As an additional bonus, now there is no need to register MDIO bus for each PHY, all emulated PHYs placed on the platform fixed MDIO bus. There is also no more need to pre-allocate PHYs via .config option, this is all now handled dynamically.

Then, it reworks the interaction between this and the via-pmu sleep code to properly restore backlight on wakeup from sleep.

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.

The problem caused is one cannot compile userspace apps (ex. libkvm) for other archs since a size cannot be determined for these structures.

That means kvm needs to vet the feature set before it is passed to the guest. - No support for indexed or stateful cpuid entries Some cpuid entries depend on ecx as well as on eax, or on internal state in the processor (running cpuid multiple times with the same input returns different output). The current cpuid machinery only supports keying on eax. - No support for save/restore/migrate The internal state above needs to be exposed to userspace so it can be saved or migrated. This patch adds extended cpuid support by means of three new ioctls: - KVM_GET_SUPPORTED_CPUID: get all cpuid entries the host (and kvm) supports - KVM_SET_CPUID2: sets the vcpu's cpuid table - KVM_GET_CPUID2: gets the vcpu's cpuid table, including hidden state [avi: fix original KVM_SET_CPUID not removing nx on non-nx hosts as it did before] Signed-off-by: Dan Kenigsberg <danken@qumranet.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
