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
