pgalloc() grows a process heap for sbrk(). It extended the address environment of the running task (addrenv_own). While exec() sets up a new process, the caller selects the new address environment and allocates the new process's stack from its heap. When that stack does not fit in the initial heap, the heap must grow, but the running task is the caller. For the kernel thread that starts init this was an assertion; for a user task it would have grown the caller's heap. Use the selected address environment (addrenv_curr). For a normal sbrk() it is the same as addrenv_own. Assisted-by: Claude Code:claude-opus-5-5 Signed-off-by: Marco Casaroli <marco.casaroli@gmail.com> |
