2017-05-01bpf: Move endianness BPF helpers out of bpf_util.hDavid S. Miller4-21/+25
We do not want to include things like stdio.h and friends into eBPF program builds. bpf_util.h is for host compiled programs, so eBPF C-code helpers don't really belong there. Add a new bpf_endian.h as a quick fix for this for now. Signed-off-by: David S. Miller <[email protected]>
2017-05-01bpf: enhance verifier to understand stack pointer arithmeticYonghong Song1-6/+12
llvm 4.0 and above generates the code like below: .... 440: (b7) r1 = 15 441: (05) goto pc+73 515: (79) r6 = *(u64 *)(r10 -152) 516: (bf) r7 = r10 517: (07) r7 += -112 518: (bf) r2 = r7 519: (0f) r2 += r1 520: (71) r1 = *(u8 *)(r8 +0) 521: (73) *(u8 *)(r2 +45) = r1 .... and the verifier complains "R2 invalid mem access 'inv'" for insn #521. This is because verifier marks register r2 as unknown value after #519 where r2 is a stack pointer and r1 holds a constant value. Teach verifier to recognize "stack_ptr + imm" and "stack_ptr + reg with const val" as valid stack_ptr with new offset.

2017-04-28bpf: provide a generic macro for percpu values for selftestsDaniel Borkmann2-17/+27
To overcome bugs as described and fixed in 89087c456fb5 ("bpf: Fix values type used in test_maps"), provide a generic BPF_DECLARE_PERCPU() and bpf_percpu() accessor macro for all percpu map values used in tests. Declaring variables works as follows (also works for structs): BPF_DECLARE_PERCPU(uint32_t, my_value); They can then be accessed normally as uint32_t type through: bpf_percpu(my_value, <cpu_nr>) For example: bpf_percpu(my_value, 0)++; Implicitly, we make sure that the passed type is allocated and aligned by gcc at least on a 8-byte boundary, so that it works together with the map lookup/update syscall for percpu maps. We use it as a usage example in test_maps, so that others are free to adapt this into their code when necessary.

2017-04-28bpf: fix _htons occurences in test_progsDaniel Borkmann4-15/+31
Dave reported that on sparc test_progs generates buggy swapped eth->h_proto protocol comparisons: 10: (15) if r3 == 0xdd86 goto pc+9 R0=imm2,min_value=2,max_value=2 R1=pkt(id=0,off=0,r=14) R2=pkt_end R3=inv R4=pkt(id=0,off=14,r=14) R5=inv56 R10=fp This is due to the unconditional ... #define htons __builtin_bswap16 #define ntohs __builtin_bswap16 ... in test_progs that causes this. Make use of asm/byteorder.h and use __constant_htons() where possible and only perform the bswap16 when on little endian in non-constant case.

2017-04-26selftests: ftrace: Allow some tests to be run in a tracing instanceSteven Rostedt (VMware)1-1/+17
An tracing instance has several of the same capabilities as the top level instance, but may be implemented slightly different. Instead of just writing tests that duplicat the same test cases of the top level instance, allow a test to be written for both the top level as well as for an instance. If a test case can be run in both the top level as well as in an tracing instance directory, then it should add a tag "# flags: instance" in the header of the test file. Then after all tests have run, any test that has an instance flag set, will run again within a tracing instance.

When iterating through a map, we need to find a key that does not exist in the map so map_get_next_key will give us the first key of the map. This often requires a lot of guessing in production systems. This patch makes map_get_next_key return the first key when the key pointer in the parameter is NULL.
