When trying to add a name to the hashmap, an error code of EEXIST is returned and we continue as names are possibly duplicated in the sys file. If the last name in the file is a duplicate, we will continue to the next iteration of the while loop, and exit the loop with a value of err set to EEXIST and enter the error label with err set, which causes the test to fail when it should not. This change reset err to 0 before continue-ing into the next iteration, this way, if there is no more data to read from the file we iterate through, err will be set to 0. Behaviour prior to this change: ``` test_kprobe_multi_bench_attach:FAIL:get_syms unexpected error: -17 (errno 2) All error logs: test_kprobe_multi_bench_attach:FAIL:get_syms unexpected error: -17 (errno 2) Summary: 0/1 PASSED, 0 SKIPPED, 1 FAILED ``` After this change: ``` Summary: 1/2 PASSED, 0 SKIPPED, 0 FAILED ``` Signed-off-by: Manu Bretelle <chantr4@gmail.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20230408022919.54601-1-chantr4@gmail.com
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.
