pppoe: fix memcpy out of bounds with gcc-11 on arm
In function ‘memcpy’, inlined from ‘clib_memcpy_fast’ at /home/vpp/src/vppinfra/string.h:86:10, inlined from ‘memcpy_s_inline’ at /home/vpp/src/vppinfra/string.h:157:7, inlined from ‘vnet_pppoe_add_del_session’ at /home/vpp/src/plugins/pppoe/pppoe.c:356:7: error: ‘__builtin_memcpy’ offset [0, 5] is out of the bounds [0, 0] [-Werror=array-bounds] 34 | return __builtin___memcpy_chk (__dest, __src, __len, __bos0 (__dest)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Cc1: all warnings being treated as errors Hardware address is zero length vector for PPP, use vec_len instead. Type: fix Fixes: 62f9cdd82c52 ("Add PPPoE Plugin") Signed-off-by: Tianyu Li <tianyu.li@arm.com> Change-Id: If9fb409cfbbac77c15559d103987f0130bf30255
