solved and the nightmare is complete, here's the next one: speculating after RET instructions and leaking privileged information using the now pretty much classical covert channels. It is called RETBleed and the mitigation effort and controlling functionality has been modelled similar to what already existing mitigations provide. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEzv7L6UO9uDPlPSfHEsHwGGHeVUoFAmLNdDYACgkQEsHwGGHe VUrNAw/+OTFF7md0+17Ju6vvagc/nXfUxk/r0lWU9/KzbRXvPTZdPKTW4NN5c0IS VnogyUGFFpzU3dKU2os9ejTD4kHNx0oLuBfQt4w7t4qR+g3+nAH0ywNjH/N1VTJt iDpww7CxqloV+i9RCsWV+zQPMPfc2VMUhe6xqNB2CgEDrruzFrDASZR6zzarsKxY x4rwHn0ZkV7zNJfcNpV2323qktqHgBtAFf7GlZK8hBsgsiSk+xDk9CODkfxfWIV7 o4BNvNmaUKDJL51hpuzvIzYwDSiRO5AXdjxHG/0CHc3r3dtA6Xt1elHbERAyUMuM P+6XievP5ZV/xXXjoZ5Vla67o3bbGKmTo2WluvVGeg8ahzQEwyPGqeXn77hk+of+ BtasZyLgfdwSeWExxp0n5Nhh972TMpy5K4gqOFXcxvPSuTl6tTw77F1u0UQLaVVH QzHNu+RO/2iQ/P30cOM11IbZ9sfcBOj+5mjfoDoR4qCtoCQfyfHK+HlwXjZ+uk98 xU/FnQbOKPRVxiyCVhrbKFxjW7iL7AIb0nRgxHzGGoIJ6A71Tbwa/5gGakE7WEBz e7ce8NW2JFucGBFYyiBab6I6fB7lbvmqbNPerYEVoU5YxZkMu+xxyToqBnsyPfHZ lxgEGREUaY8aZmGDfrD9EYyhhtQU/MwdpN+FY3xXQdUJkvkNaLg= =0Ca0 -----END PGP SIGNATURE----- Merge tag 'x86_bugs_retbleed' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull lockdep fix for x86 retbleed from Borislav Petkov: - Fix lockdep complaint for __static_call_fixup() * tag 'x86_bugs_retbleed' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/static_call: Serialize __static_call_fixup() properly
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
