commit26b483d524upstream. This reverts commite057b94772. Sashiko points out that updating 'orig_x0' after secure_computing() has returned is too late to handle the case where a seccomp filter is re-evaluated after initially returning SECCOMP_RET_TRACE. This means that a tracer can manipulate the first argument of the syscall behind seccomp's back. For now, revert the initial fix and we'll have another crack at it soon. Since the incorrect fix was cc'd to stable, do the same here with an appropriate fixes tag.

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.
