ash: fix here strings causing segfault in function invocation

2026-03-09T14:23:59+00:00

The size of the NFROMSTR struct wasn't initialised in the nodesize array, so we got: $ ./busybox sh $ f() { cat <<< hello; } $ f Segmentation fault (core dumped) ./busybox sh Signed-off-by: Ron Yorston Signed-off-by: Denys Vlasenko

ash: fix help builtin and tab completion of builtins

2026-02-28T10:25:05+00:00

Commit 56143ea63 (ash: code shrink: eliminate pstrcmp1()) changed the layout of struct builtincmd so the name member points to the start of the name, not the flag in the first element of the string. This broke the help builtin and tab completion of builtins. Remove the unnecessary '+ 1' in ash_command_name() and helpcmd(). ash_command_name 92 91 -1 helpcmd 106 102 -4 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-5) Total: -5 bytes Signed-off-by: Ron Yorston Signed-off-by: Denys Vlasenko
