Christophe JAILLET 99719bb0c2 kdb: Fix a potential buffer overflow in kdb_local() ... [ Upstream commit 4f41d30cd6dc865c3cbc1a852372321eba6d4e4c ] When appending "[defcmd]" to 'kdb_prompt_str', the size of the string already in the buffer should be taken into account. An option could be to switch from strncat() to strlcat() which does the correct test to avoid such an overflow. However, this actually looks as dead code, because 'defcmd_in_progress' can't be true here. See a more detailed explanation at [1].
