The libelf implementation from elftoolchain has a safety check in gelf_update_rel[a] to check that the data corresponds to a section that has type SHT_REL[A] [0]. If the relocation is updated before the section header is updated with the proper type, this check fails. To fix this, update the section header first, before the relocations. Previously, the section size was calculated in elf_rebuild_reloc_section by counting the number of entries in the reloc_list. However, we now need the size during elf_write so instead keep a running total and add to it for every new relocation.

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.
