| H A D | bnxt_hsi.h | d3e599c0 Wed Jan 18 14:35:01 CST 2023 Kees Cook <keescook@chromium.org> bnxt: Do not read past the end of test names
Test names were being concatenated based on a offset beyond the end of
the first name, which tripped the buffer overflow detection logic:
detected buffer overflow in strnlen
[...]
Call Trace:
bnxt_ethtool_init.cold+0x18/0x18
Refactor struct hwrm_selftest_qlist_output to use an actual array,
and adjust the concatenation to use snprintf() rather than a series of
strncat() calls.
