tests: introduce midtail_alloc and use it in netlink tests netlink tests happen to access memory located before the tail_malloc'ed pointers, a practice that doesn't go well with the latest compilers because tail_malloc is marked with ATTRIBUTE_MALLOC. For example, glibc in -D_FORTIFY_SOURCE=2 mode and gcc 8 with -Warray-bounds enabled complain about negative offsets out of bounds. Fix this issue by introducing midtail_alloc. * tests/tests.h (midtail_alloc): New macro. * tests/netlink_crypto.c: Use it instead of tail_malloc for nlh0 allocation. * tests/netlink_netfilter.c: Likewise. * tests/netlink_protocol.c: Likewise. * tests/netlink_route.c: Likewise. * tests/netlink_selinux.c: Likewise. * tests/netlink_sock_diag.c: Likewise. * tests/nlattr_br_port_msg.c: Likewise. * tests/nlattr_crypto_user_alg.c: Likewise. * tests/nlattr_dcbmsg.c: Likewise. * tests/nlattr_fib_rule_hdr.c: Likewise. * tests/nlattr_ifaddrlblmsg.c: Likewise. * tests/nlattr_ifaddrmsg.c: Likewise. * tests/nlattr_ifinfomsg.c: Likewise. * tests/nlattr_ifla_brport.c: Likewise. * tests/nlattr_ifla_port.c: Likewise. * tests/nlattr_ifla_xdp.c: Likewise. * tests/nlattr_inet_diag_msg.c: Likewise. * tests/nlattr_inet_diag_req_compat.c: Likewise. * tests/nlattr_inet_diag_req_v2.c: Likewise. * tests/nlattr_mdba_mdb_entry.c: Likewise. * tests/nlattr_mdba_router_port.c: Likewise. * tests/nlattr_ndmsg.c: Likewise. * tests/nlattr_ndtmsg.c: Likewise. * tests/nlattr_netconfmsg.c: Likewise. * tests/nlattr_netlink_diag_msg.c: Likewise. * tests/nlattr_nlmsgerr.c: Likewise. * tests/nlattr_packet_diag_msg.c: Likewise. * tests/nlattr_rtgenmsg.c: Likewise. * tests/nlattr_rtmsg.c: Likewise. * tests/nlattr_smc_diag_msg.c: Likewise. * tests/nlattr_tc_stats.c: Likewise. * tests/nlattr_tca_stab.c: Likewise. * tests/nlattr_tcamsg.c: Likewise. * tests/nlattr_tcmsg.c: Likewise. * tests/nlattr_unix_diag_msg.c: Likewise.
