John Fastabend 40d526e672 bpf: fix uninitialized variable in bpf tools ... [ Upstream commit 815425567d ] Here the variable cont is used as the saved_pointer for a call to strtok_r(). It is safe to use the value uninitialized in this context however and the later reference is only ever used if the strtok_r is successful. But, 'gcc-5' at least doesn't have all this knowledge so initialize cont to NULL. Additionally, do the natural NULL check before accessing just for completness. The warning is the following: ./bpf/tools/bpf/bpf_dbg.c: In function ‘cmd_load’: ./bpf/tools/bpf/bpf_dbg.c:1077:13: warning: ‘cont’ may be used uninitialized in this function [-Wmaybe-uninitialized] } else if (matches(subcmd, "pcap") == 0) { Fixes: fd981e3c32 "filter: bpf_dbg: add minimal bpf debugger" Signed-off-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Sasha Levin <alexander.levin@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2018-06-21 04:02:49 +09:00
