KVM: Fix user memslot overlap check

2013-01-17T16:45:52Z

commit 5419369ed6bd4cf711fdda5e52a5999b940413f5 upstream. Prior to memory slot sorting this loop compared all of the user memory slots for overlap with new entries. With memory slot sorting, we're just checking some number of entries in the array that may or may not be user slots. Instead, walk all the slots with kvm_for_each_memslot, which has the added benefit of terminating early when we hit the first empty slot, and skip comparison to private slots.

KVM: make processes waiting on vcpu mutex killable

2012-09-17T16:46:32Z

vcpu mutex can be held for unlimited time so taking it with mutex_lock on an ioctl is wrong: one process could be passed a vcpu fd and call this ioctl on the vcpu used by another process, it will then be unkillable until the owner exits. Call mutex_lock_killable instead and return status. Note: mutex_lock_interruptible would be even nicer, but I am not sure all users are prepared to handle EINTR from these ioctls. They might misinterpret it as an error. Cleanup paths expect a vcpu that can't be used by any userspace so this will always succeed - catch bugs by calling BUG_ON. Catch callers that don't check return state by adding __must_check. Signed-off-by: Michael S. Tsirkin Signed-off-by: Marcelo Tosatti

KVM: PPC: book3s: fix build error caused by gfn_to_hva_memslot()

2012-08-27T19:44:20Z

The build error was caused by that builtin functions are calling the functions implemented in modules. This error was introduced by commit 4d8b81abc4 ("KVM: introduce readonly memslot"). The patch fixes the build error by moving function __gfn_to_hva_memslot() from kvm_main.c to kvm_host.h and making that "inline" so that the builtin function (kvmppc_h_enter) can use that.
