M. Mert Yıldıran 52c9251c00 Add ABI0 support to Go crypto/tls eBPF tracer (#1169) ... * Determine the Go ABI and get `goid` offset from DWARF * Add `ABI` enum and morph the function according to the detected ABI * Pass `goid` offset to an eBPF map to retrieve it in eBPF context * Add `vmlinux.h` and implement `get_goid_from_thread_local_storage` * Fix BPF verifier errors * Update the comments * Add `go_abi_0.h` and implement `ABI0` specific reads for `arm64` * Upgrade `github.com/cilium/ebpf` to `v0.9.0` * Add a comment * Add macros for x86 specific parts * Update `x86.o` * Fix the map key type * Add `user_pt_regs` * Update arm64 object file * Fix the version detection logic * Add `getGStructOffset` method * Define `goid_offsets`, `goid_offsets_map` structs and pass the offsets correctly * Fix the `net.TCPConn` and buffer addresses for `ABI0` * Remove comment * Fix the issues for arm64 build * Update x86.o * Revert "Fix the issues for arm64 build" This reverts commit 48b041b1b6. * Revert `user_pt_regs` * Add `vmlinux` directory * Fix the `build.sh` and `Dockerfile` * Add vmlinux_arm64.h * Disable `get_goid_from_thread_local_storage` on ARM64 with a macro * Update x86.o * Update arm64.o * x86 * arm64 * Fix the cross-compilation issue from x86 to arm64 * Fix the same thing for x86 * Use `BPF_CORE_READ` macro instead of `bpf_ringbuf_reserve` to support kernel versions older than 5.8 Also; Add legacy version of thread_struct: thread_struct___v46 Build an additional object file for the kernel versions older than or equal to 4.6 and load them accordingly. Add github.com/moby/moby * Make #define directives more definitive * Select the x86 and arm64 versions of `vmlinux.h` using macros * Put `goid` offsets into the map before installing `uprobe`(s) * arm64 * #run_acceptance_tests * Remove a forgotten `fmt.Printf` * Log the detected Linux kernel version		2022-07-05 14:35:30 +03:00
