While reviewing another part of the code, Kees noticed that the strncpy of the partition name might not always be NUL terminated. Switch to using strlcpy which does this safely. Reported-by: Kees Cook <keescook@xxxxxxxxxxxx> Signed-off-by: Laura Abbott <labbott@xxxxxxxxxx> --- I realized looking at this that I probably should have made this and my previous patch a series given this has context depending on the other patch.
