2018-04-26bpf: fix uninitialized variable in bpf toolsJohn Fastabend1-2/+5
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: fd981e3c321a "filter: bpf_dbg: add minimal bpf debugger" Signed-off-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
2017-10-05tools: rename tools/net directory to tools/bpfJakub Kicinski1-0/+1395
We currently only have BPF tools in the tools/net directory. We are about to add more BPF tools there, not necessarily networking related, rename the directory and related Makefile targets to bpf.
