Linux kernel source tree
386c5680e2
The lifetime managment uses '__u64' timestamps on the user space interface, but 'unsigned long' for reading the current time in the kernel with get_seconds(). While this is probably safe beyond y2038, it will still overflow in 2106, and the get_seconds() call is deprecated because fo that. This changes the xfrm time handling to use time64_t consistently, along with reading the time using the safer ktime_get_real_seconds(). It still suffers from problems that can happen from a concurrent settimeofday() call or (to a lesser degree) a leap second update, but since the time stamps are part of the user API, there is nothing we can do to prevent that.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
