When dumping a character array, libbpf will watch for a '\0' and set
is_array_terminated=true if found. This prevents libbpf from printing
the remaining characters of the array, treating it as a nul-terminated
string.
However, once this flag is set, it's never reset, leading to subsequent
characters array not being printed properly:
.str_multi = (__u8[2][16])[
[
'H',
'e',
'l',
],
],
This patch saves the is_array_terminated flag and restores its
default (false) value before looping over the elements of an array,
then restores it afterward. This way, libbpf's behavior is unchanged
when dumping the characters of an array, but subsequent arrays are
printed properly:
.str_multi = (__u8[2][16])[
[
'H',
'e',
'l',
],
[
'l',
'o',
],
],

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 reStructuredText 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.
