Pull kvm fixes from Paolo Bonzini: "Bugfixes, mostly for ARM and AMD, and more documentation. Slightly bigger than usual because I couldn't send out what was pending for rc4, but there is nothing worrisome going on. I have more fixes pending for guest debugging support (gdbstub) but I will send them next week" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (22 commits) KVM: X86: Declare KVM_CAP_SET_GUEST_DEBUG properly KVM: selftests: Fix build for evmcs.h kvm: x86: Use KVM CPU capabilities to determine CR4 reserved bits KVM: VMX: Explicitly clear RFLAGS.CF and RFLAGS.ZF in VM-Exit RSB path docs/virt/kvm: Document configuring and running nested guests KVM: s390: Remove false WARN_ON_ONCE for the PQAP instruction kvm: ioapic: Restrict lazy EOI update to edge-triggered interrupts KVM: x86: Fixes posted interrupt check for IRQs delivery modes KVM: SVM: fill in kvm_run->debug.arch.dr[67] KVM: nVMX: Replace a BUG_ON(1) with BUG() to squash clang warning KVM: arm64: Fix 32bit PC wrap-around KVM: arm64: vgic-v4: Initialize GICv4.1 even in the absence of a virtual ITS KVM: arm64: Save/restore sp_el0 as part of __guest_enter KVM: arm64: Delete duplicated label in invalid_vector KVM: arm64: vgic-its: Fix memory leak on the error path of vgic_add_lpi() KVM: arm64: vgic-v3: Retire all pending LPIs on vcpu destroy KVM: arm: vgic-v2: Only use the virtual state when userspace accesses pending bits KVM: arm: vgic: Only use the virtual state when userspace accesses enable bits KVM: arm: vgic: Synchronize the whole guest on GIC{D,R}_I{S,C}ACTIVER read KVM: arm64: PSCI: Forbid 64bit functions for 32bit guests ...

menu "Certificates for signature checking"
config MODULE_SIG_KEY
string "File name or PKCS#11 URI of module signing key"
default "certs/signing_key.pem"
depends on MODULE_SIG
help
Provide the file name of a private key/certificate in PEM format,
or a PKCS#11 URI according to RFC7512. The file should contain, or
the URI should identify, both the certificate and its corresponding
private key.
If this option is unchanged from its default "certs/signing_key.pem",
then the kernel will automatically generate the private key and
certificate as described in Documentation/admin-guide/module-signing.rst
config SYSTEM_TRUSTED_KEYRING
bool "Provide system-wide ring of trusted keys"
depends on KEYS
depends on ASYMMETRIC_KEY_TYPE
help
Provide a system keyring to which trusted keys can be added. Keys in
the keyring are considered to be trusted. Keys may be added at will
by the kernel from compiled-in data and from hardware key stores, but
userspace may only add extra keys if those keys can be verified by
keys already in the keyring.
Keys in this keyring are used by module signature checking.
config SYSTEM_TRUSTED_KEYS
string "Additional X.509 keys for default system keyring"
depends on SYSTEM_TRUSTED_KEYRING
help
If set, this option should be the filename of a PEM-formatted file
containing trusted X.509 certificates to be included in the default
system keyring. Any certificate used for module signing is implicitly
also trusted.
NOTE: If you previously provided keys for the system keyring in the
form of DER-encoded *.x509 files in the top-level build directory,
those are no longer used. You will need to set this option instead.
config SYSTEM_EXTRA_CERTIFICATE
bool "Reserve area for inserting a certificate without recompiling"
depends on SYSTEM_TRUSTED_KEYRING
help
If set, space for an extra certificate will be reserved in the kernel
image. This allows introducing a trusted certificate to the default
system keyring without recompiling the kernel.
config SYSTEM_EXTRA_CERTIFICATE_SIZE
int "Number of bytes to reserve for the extra certificate"
depends on SYSTEM_EXTRA_CERTIFICATE
default 4096
help
This is the number of bytes reserved in the kernel image for a
certificate to be inserted.
config SECONDARY_TRUSTED_KEYRING
bool "Provide a keyring to which extra trustable keys may be added"
depends on SYSTEM_TRUSTED_KEYRING
help
If set, provide a keyring to which extra keys may be added, provided
those keys are not blacklisted and are vouched for by a key built
into the kernel or already in the secondary trusted keyring.
config SYSTEM_BLACKLIST_KEYRING
bool "Provide system-wide ring of blacklisted keys"
depends on KEYS
help
Provide a system keyring to which blacklisted keys can be added.
Keys in the keyring are considered entirely untrusted. Keys in this
keyring are used by the module signature checking to reject loading
of modules signed with a blacklisted key.
config SYSTEM_BLACKLIST_HASH_LIST
string "Hashes to be preloaded into the system blacklist keyring"
depends on SYSTEM_BLACKLIST_KEYRING
help
If set, this option should be the filename of a list of hashes in the
form "<hash>", "<hash>", ... . This will be included into a C
wrapper to incorporate the list into the kernel. Each <hash> should
be a string of hex digits.
