[ Upstream commit cb4969e6f9f5ee12521aec764fa3d4bbd91bc797 ]
Currently the following command produces an error message:
linux# make kselftest TARGETS=bpf O=/mnt/linux-build
# selftests: bpf: test_libbpf.sh
# ./test_libbpf.sh: line 23: ./test_libbpf_open: No such file or directory
# test_libbpf: failed at file test_l4lb.o
# selftests: test_libbpf [FAILED]
The error message might not affect the return code of make, therefore
one needs to grep make output in order to detect it.
This is not the only instance of the same underlying problem; any test
with more than one element in $(TEST_PROGS) fails the same way. Another
example:
linux# make O=/mnt/linux-build TARGETS=splice kselftest
[...]
# ./short_splice_read.sh: 15: ./splice_read: not found
# FAIL: /sys/module/test_module/sections/.init.text 2
not ok 2 selftests: splice: short_splice_read.sh # exit=1
The current logic prepends $(OUTPUT) only to the first member of
$(TEST_PROGS). After that, run_one() does
cd `dirname $TEST`
For all tests except the first one, `dirname $TEST` is ., which means
they cannot access the files generated in $(OUTPUT).
Fix by using $(addprefix) to prepend $(OUTPUT)/ to each member of
$(TEST_PROGS).

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.
