I fixed some issues that Jens pointed out, and also the TODOs that I left
in the previous version.
I still have any doubts about patch 3, any advice?
RFC v1 -> RFC v2:
- added 'restricted' flag in the ctx [Jens]
- added IORING_MAX_RESTRICTIONS define
- returned EBUSY instead of EINVAL
The enumeration allows us to keep track of the last
io_uring_register(2) opcode available.
Behaviour and opcodes names don't change.

The new io_uring_register(2) IOURING_REGISTER_RESTRICTIONS opcode
permanently installs a feature allowlist on an io_ring_ctx.
The io_ring_ctx can then be passed to untrusted code with the
knowledge that only operations present in the allowlist can be
executed.
The allowlist approach ensures that n

This patch adds a new IORING_SETUP_R_DISABLED flag to start the

buffers, files, before to start processing SQEs.
When IORING_SETUP_R_DISABLED is set, SQE are not processed and
SQPOLL kthread is not started.

Configure SGX as part of feature control MSR initialization and update
the associated X86_FEATURE flags accordingly. Because the kernel will

Define the SGX microarchitectural data structures used by various SGX
opcodes. This is not an exhaustive representation of all SGX data

Add vm_ops()->mprotect() for additional constraints for a VMA.
Intel Software Guard eXtensions (SGX) will use this callback to add two

Add an ioctl that performs ENCLS[ECREATE], which creates SGX Enclave
Control Structure for the enclave. SECS contains attributes about the
enclave that are used by the hardware and cannot be directly accessed by

One essential field in SECS is a field that stor

Add an ioctl that performs ENCLS[EINIT], which locks down the measurement

Add an ioctl, which performs ENCLS[EADD] that adds new visible page to an
enclave, and optionally ENCLS[EEXTEND] operations that hash the page to the
enclave measurement. By visible we mean a page that can be mapped to the
address range of an enclave.
