+
+Go does not follow any platform ABI like x86-64 System V ABI.
+Before 1.17, Go followed stack-based Plan9 (Bell Labs) calling convention. (ABI0)
+After 1.17, Go switched to an internal register-based calling convention. (ABIInternal)
+For now, the probes in this file supports only ABIInternal (Go 1.17+)
+
+`uretprobe` in Linux kernel uses trampoline pattern to jump to original return
+address of the probed function. A Goroutine's stack size is 2Kb while a C thread is 2MB on Linux.
+If stack size exceeds 2Kb, Go runtime relocates the stack. That causes the
+return address to become incorrect in case of `uretprobe` and probed Go program crashes.
+Therefore `uretprobe` CAN'T BE USED for a Go program.
+
+`_ex_uprobe` suffixed probes suppose to be `uretprobe`(s) are actually `uprobe`(s)
+because of the non-standard ABI of Go. Therefore we probe all `ret` mnemonics under the symbol
+by automatically finding them through reading the ELF binary and disassembling the symbols.
+Disassembly related code located in `go_offsets.go` file and it uses Capstone Engine.
+Solution based on: https://github.com/iovisor/bcc/issues/1320#issuecomment-407927542
+*Example* We probe an arbitrary point in a function body (offset +559):
+https://github.com/golang/go/blob/go1.17.6/src/crypto/tls/conn.go#L1299
+
+We get the file descriptor using the common $rax register that holds the address
+of `go.itab.*net.TCPConn,net.Conn` and through a series of dereferencing
+using `bpf_probe_read` calls in `go_crypto_tls_get_fd_from_tcp_conn` function.
