Crate ping 

ping : ICMP echo utility for strat9-os

Sends ICMP echo requests by writing to /net/ping/<target_ip> and reads replies from the same scheme path. The actual ICMP socket is driven by the strate-net silo via smoltcp; this tool is a thin userspace wrapper.

Usage: ping [-6] [-c count] [ip|hostname] [count]

All I/O is done through Plan 9–style schemes (no BSD sockets).

Functions

__align_up 🔒

Implements align up.

__alloc_size 🔒

Implements alloc size.

__lock_alloc 🔒

Implements lock alloc.

__unlock_alloc 🔒

Implements unlock alloc.

_start^⚠

Entry point: captures the initial RSP (= SysV stack pointer) and calls start_impl. Using a naked function guarantees that no prologue has modified RSP before we pass it as rdi.

alloc_error 🔒

Implements alloc error.

apply_family_constraint 🔒

clock_ns 🔒

Implements clock ns.

copy_target 🔒

cstr_to_str 🔒 ^⚠

Convert a null-terminated C string pointer to a &'static str.

family_flag 🔒

family_name 🔒

log 🔒

Implements log.

log_u32 🔒

Implements log u32.

panic 🔒

parse_args_from_stack 🔒

Build PingArgs from the SysV initial user stack.

print_usage 🔒

read_default_target 🔒

resolve_target 🔒

scheme_close 🔒

Close a scheme fd.

scheme_open 🔒

Open a scheme file, return fd.

scheme_read_fd 🔒

Read from an open scheme fd, return bytes read.

scheme_write_fd 🔒

Write to an open scheme fd, return bytes written.

sleep_ms 🔒

Implements sleep ms.

start_impl 🔒

Main program logic; called from the naked _start trampoline.

str_to_u32 🔒

Parse an ASCII decimal string into a u32.

u32_to_str 🔒

Implements u32 to str.
