Due to kptr_restrict, JITted BPF code is now displayed like this: 000000000b6ed1b2: ebdff0800024 stmg %r13,%r15,128(%r15) 000000004cde2ba0: 41d0f040 la %r13,64(%r15) 00000000fbad41b0: a7fbffa0 aghi %r15,-96 Leaking kernel addresses to dmesg is not a concern in this case, because this happens only when JIT debugging is explicitly activated, which only root can do. Use %px in this particular instance, and also to print an instruction address in show_code and PCREL (e.g. brasl) arguments in print_insn. While at present functionally equivalent to %016lx, %px is recommended by Documentation/core-api/printk-formats.rst for such cases.

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.
