2022-03-23libbpf-tools: improve check for fentry program supportConnor O'Brien
On architectures that lack support for fentry programs, tools should fall back to using kprobes even if the kernel version is new enough to include BPF_TRACE_FENTRY, but fentry_exists() cannot currently detect this case. Instead of searching for BPF_TRACE_FENTRY, verify that attaching a BPF_TRACE_FENTRY program can actually succeed. Rename fentry_exists to fentry_can_attach to reflect this change.

usdt: support xmm registers as args for x64
2022-03-16usdt: support xmm registers as args for x64Dave Marchevsky
Support for using xmm registers for USDT args was added to systemtap in early 2021 (commit 04c99d0d0267f574fa60044c96933b0dd3846aa1 added xmm0-7 and eaa15b047688175a94e3ae796529785a3a0af208 added xmm8-15). As a result these registers are showing up in probe descriptors on Fedora. pthread_start probe description on Ubuntu 20.04: ``` stapsdt 0x00000052 NT_STAPSDT (SystemTap probe descriptors) Provider: libpthread Name: pthread_start Location: 0x00000000000095e9, Base: 0x000000000001922c, Semaphore: 0x0000000000000000 Arguments: 8@%rax 8@1600(%rax) 8@1608(%rax) ``` And in the Fedora test container: ``` ``` stapsdt 0x00000053 NT_STAPSDT (SystemTap probe descriptors) Provider: libpthread Name: pthread_start Location: 0x0000000000009280, Base: 0x0000000000016cbc, Semaphore: 0x0000000000000000 Arguments: 8@%xmm0 8@1600(%rax) 8@1608(%rax) ``` bcc doesn't recognize these registers so it's unable to generate code to fetch arguments which use these registers for storage. Add support for XMM0-15. This should fix `lib/uthreads.py` test, which uses `pthread_start` and therefore fails to generate program on Fedora. Signed-off-by: Dave Marchevsky <davemarchevsky@fb.com>
2022-03-16libbpf-tools: Allow to use different cflags for bpf targetsJerome Marchand
commit 531b698cdc20 ("libbpf-tools: Enable compilation warnings for BPF programs") applies CFLAGS to all targets. However, some of the c flags typically used by distribution are not available to the bpf target. Add a new BPFCFLAGS macro to take care of that. Fixes the following compilation error on fedora: BPF bashreadline.bpf.o clang-13: warning: optimization flag '-ffat-lto-objects' is not supported [-Wignored-optimization-argument] clang-13: warning: argument unused during compilation: '-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1' [-Wunused-command-line-argument] clang-13: warning: argument unused during compilation: '-specs=/usr/lib/rpm/redhat/redhat-annobin-cc1' [-Wunused-command-line-argument] clang-13: warning: argument unused during compilation: '-fstack-clash-protection' [-Wunused-command-line-argument] error: option 'cf-protection=return' cannot be specified on this target error: option 'cf-protection=branch' cannot be specified on this target 2 errors generated.
