[PATCH 08/30] aio: implement IOCB_CMD_POLL

Simple one-shot poll through the io_submit() interface. To poll for a file descriptor the application should submit an iocb of type IOCB_CMD_POLL. It will poll the fd for the events specified in the the first 32 bits of the aio_buf field of the iocb. Unlike poll or epoll without EPOLLONESHOT thi

[PATCH 05/30] fs: introduce new ->get_poll_head and ->poll_mask methods

->get_poll_head returns the waitqueue that the poll operation is going to sleep on. Note that this means we can only use a single waitqueue for the poll, unlike some current drivers that use two waitqueues for different events. But now that we have keyed wakeups and heavily use those for poll the

[PATCH 06/30] aio: simplify cancellation

With the current aio code there is no need for the magic KIOCB_CANCELLED value, as a cancelation just kicks the driver to queue the completion ASAP, with all actual completion handling done in another thread. Given that both the completion path and cancelation take the context lock there is no need

[PATCH 07/30] aio: add delayed cancel support

The upcoming aio poll support would like to be able to complete the iocb inline from the cancellation context, but that would cause a double lock of ctx_lock with the current locking scheme. Move the cancelation outside the context lock to avoid this reversal, which suits the existing usb gadgets

[PATCH v3 0/1] Safe LSM (un)loading, and immutable hooks

The biggest security benefit of this patchset is the introduction of read-only hooks. Currently, if you have any LSMs with mutable hooks it will render all heads, and list nodes mutable. This is a prime place to attack, because being able to manipulate those hooks is a way to bypass all LSMs easily

[PATCH v3 1/1] security: Add mechanism to safely (un)load LSMs after boot time

This patch introduces a mechanism to add mutable hooks and immutable hooks to the callback chain. It adds an intermediary item to the chain which separates mutable and immutable hooks. Immutable hooks are then marked as read-only, as well as the hook heads. This does not preclude some hooks being a
