tools lib traceevent: Change tag string for error

2019-05-02T20:00:19Z

The traceevent lib is used by the perf tool, and when executing perf test -v 6 it outputs error log on the ARM64 platform: running test 33 '*:*'trace-cmd: No such file or directory [...] trace-cmd: Invalid argument The trace event parsing code originally came from trace-cmd so it keeps the tag string "trace-cmd" for errors, this easily introduces the impression that the perf tool launches trace-cmd command for trace event parsing, but in fact the related parsing is accomplished by the traceevent lib. This patch changes the tag string to "libtraceevent" so that we can avoid confusion and let users to more easily connect the error with traceevent lib.

tools lib traceevent: Fix missing equality check for strcmp

2019-04-16T14:27:36Z

There was a missing comparison with 0 when checking if type is "s64" or "u64". Therefore, the body of the if-statement was entered if "type" was "u64" or not "s64", which made the first strcmp() redundant since if type is "u64", it's not "s64". If type is "s64", the body of the if-statement is not entered but since the remainder of the function consists of if-statements which will not be entered if type is "s64", we will just return "val", which is correct, albeit at the cost of a few more calls to strcmp(), i.e., it will behave just as if the if-statement was entered. If type is neither "s64" or "u64", the body of the if-statement will be entered incorrectly and "val" returned. This means that any type that is checked after "s64" and "u64" is handled the same way as "s64" and "u64", i.e., the limiting of "val" to fit in for example "s8" is never reached. This was introduced in the kernel tree when the sources were copied from trace-cmd in commit f7d82350e597 ("tools/events: Add files to create libtraceevent.a"), and in the trace-cmd repo in 1cdbae6035cei ("Implement typecasting in parser") when the function was introduced, i.e., it has always behaved the wrong way. Detected by cppcheck.

bpf, libbpf: fix quiet install_headers

2019-03-28T16:01:37Z

Both btf.h and xsk.h headers are not installed quietly due to missing '\' for the call to QUIET_INSTALL. Lets fix it. Before: # make install_headers INSTALL headers if [ ! -d '''/usr/local/include/bpf' ]; then install -d -m 755 '''/usr/local/include/bpf'; fi; install btf.h -m 644 '''/usr/local/include/bpf'; if [ ! -d '''/usr/local/include/bpf' ]; then install -d -m 755 '''/usr/local/include/bpf'; fi; install xsk.h -m 644 '''/usr/local/include/bpf'; # ls /usr/local/include/bpf/ bpf.h btf.h libbpf.h xsk.h After: # make install_headers INSTALL headers # ls /usr/local/include/bpf/ bpf.h btf.h libbpf.h xsk.h Fixes: a493f5f9d8c2 ("libbpf: Install btf.h with libbpf") Fixes: 379e2014c95b ("libbpf: add xsk.h to install_headers target") Signed-off-by: Daniel Borkmann Acked-by: Alexei Starovoitov Acked-by: Andrii Nakryiko

libbpf: add libelf dependency to shared library build

2019-03-28T15:24:52Z

The DPDK project is moving forward with its AF_XDP PMD, and during that process some libbpf issues surfaced [1]: When libbpf was built as a shared library, libelf was not included in the linking phase. Since libelf is an internal depedency to libbpf, libelf should be included. This patch adds '-lelf' to resolve that.
