/*
|
|
* The payload's built-in shell.
|
|
*
|
|
* The PS5 has no /bin/sh, so this implements ~44 commands itself (ls,
|
|
* cat, grep, find, df, ps, …). It lived inside runtime.c as a single
|
|
* 1,981-line function in an 18,600-line file, which is most of why that
|
|
* file was too large to audit — a duplicate app.db reader hid in there
|
|
* for months.
|
|
*
|
|
* Split out because it is almost entirely self-contained: it needs
|
|
* nothing from the runtime except two helpers, declared below. The
|
|
* frame plumbing (shell_send_json_result, handle_shell_exec) stays in
|
|
* runtime.c, since that genuinely does need runtime_state_t.
