[SRU][N/P/Q][PATCH 0/1] UBUNTU: SAUCE: selftests: net: fix "buffer overflow detected" for tap.c

[Alice C. Munduruca]

BugLink: https://bugs.launchpad.net/bugs/2067642

[ Impact ]

Currently, the default enablement of `-D_FORTIFY_SOURCE=3` in gcc causes
the kselftest net:tap test to fail due to an error in userspace. As this is not
an issue with the kernel, the test itself is changed to no longer use a checked
function (in this case using `memcpy`) to return to the previous behavior.

[ Fix ]

questing: replace the call to strcpy() with memcpy(), which is not checked.
plucky: cleanly applied questing patch.
noble: cleanly applied questing patch.
jammy: Unaffected as the jammy toolchain doesn't enable this option.

[ Test Plan ]

Run the test before and after the patch and notice the difference.

[ Regression Potential ]

N/A, Kernel is not modified by this patch.
