| * selftests: netfilter: extend flowtable test script for ipsecFlorian Westphal2019-08-051-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'flow offload' expression should not offload flows that will be subject to ipsec, but it does. This results in a connectivity blackhole for the affected flows -- first packets will go through (offload happens after established state is reached), but all remaining ones bypass ipsec encryption and are thus discarded by the peer. This can be worked around by adding "rt ipsec exists accept" before the 'flow offload' rule matches. This test case will fail, support for such flows is added in next patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add 2 tests that check JIT code generation to jumps to 1st insn. 1st test is similar to syzbot reproducer. The backwards branch is never taken at runtime. 2nd test has branch to 1st insn that executes. The test is written as two bpf functions, since it's not possible to construct valid single bpf program that jumps to 1st insn.

This patch fixes bug by ensuring that we only ever associate BTF FD with program if there is a BTF.ext data that was successfully loaded into kernel, which automatically means kernel supports func_info/line_info and associated BTF FD for progs (checked and ensured also by BTF sanitization code).

| * | libbpf: fix erroneous multi-closing of BTF FDAndrii Nakryiko2019-07-271-8/+3Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Libbpf stores associated BTF FD per each instance of bpf_program. When program is unloaded, that FD is closed. This is wrong, because leads to a race and possibly closing of unrelated files, if application simultaneously opens new files while bpf_programs are unloaded. It's also unnecessary, because struct btf "owns" that FD, and btf__free(), called from bpf_object__close() will close it. Thus the fix is to never have per-program BTF FD and fetch it from obj->btf, when necessary.

And was suppose to catch if generic XDP was broken again. The tests are using veth and assumed that veth driver didn't support native driver XDP, thus it used the (ip link set) 'xdp' attach that fell back to generic-XDP. But veth gained native-XDP support in 948d4f214fde ("veth: Add driver XDP"), which caused this test script to use native-XDP.

The test passes with mlxsw netdevs since the hardware always looks at "The first Ethertype that does not point to either: VLAN, CNTAG or configurable Ethertype". Fix this by matching on the VLAN ID instead, but on the ingress side. The reason why this is not performed at egress is explained in the commit cited below.

This warning stems from the "buf" variable being passed into "write". It originated as the variable "ev" with the type union perf_event* defined in the "perf_event__synthesize_attr" function in "tools/perf/util/header.c". In the "perf_event__synthesize_attr" function they allocate space with a malloc call using ev, then go on to only assign some of the member variables before passing "ev" on as a parameter to the "process" function therefore "ev" contains uninitialized memory. Changing the malloc call to zalloc to initialize all the members of "ev" which gets rid of the warning. To reproduce this warning, build perf by running: make -C tools/perf CLANG=1 CC=clang EXTRA_CFLAGS="-fsanitize=memory\ -fsanitize-memory-track-origins" (Additionally, llvm might have to be installed and clang might have to be specified as the compiler - export CC=/usr/bin/clang) then running: tools/perf/perf record -o - ls / | tools/perf/perf --no-pager annotate\ -i - --stdio Please see the cover letter for why false positive warnings may be generated.
