2024-12-10cut: improve detection of invalid rangesRon Yorston2-12/+12
Commit 0068ce2fa (cut: add toybox-compatible options -O OUTSEP, -D, -F LIST) added detection of reversed ranges. Further improvements are possible. - The test for reversed ranges compared the start after it had been decremented with the end before decrement. It thus missed ranges of the form 2-1. - Zero isn't a valid start value for a range. (Nor is it a valid end value, but that's caught by the test for a reversed range.) - The code if (!*ltok) e = INT_MAX; duplicates a check that's already been made. - Display the actual range in the error message to make it easier to find which range was at fault. function old new delta .rodata 100273 100287 +14 cut_main 1239 1237 -2 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/1 up/down: 14/-2) Total: 12 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2024-12-10cut: fix "-s" flag to omit blank linesColin McAllister2-5/+24
Using cut with the delimiter flag ("-d") with the "-s" flag to only output lines containing the delimiter will print blank lines. This is deviant behavior from cut provided by GNU Coreutils. Blank lines should be omitted if "-s" is used with "-d". This change introduces a somewhat naiive, yet efficient solution, where line length is checked before looping though bytes. If line length is zero and the "-s" flag is used, the code will jump to parsing the next line to avoid printing a newline character. function old new delta cut_main 1196 1185 -11 Signed-off-by: Colin McAllister <colinmca242@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2024-12-09hush: fix G.argv0_for_re_execing to avoid endless loopHajime Tazaki1-0/+3
When the busybox is used as /sbin/init and the inittab file contains below: ::respawn:-/bin/sh /sbin/init spawns hush for the first time with the argv[0] contains '-', and hush treats it as login shell. Then it reads /etc/profile and if the file contains the command execution like below, it invokes hush as login shell because the argv[0] argument is still '-/bin/sh' and reads /etc/profile again. This will last until some failure (e.g., memory failure) happens. [ "$(id -u)" -eq 0 ] && PS1="${PS1}# " || PS1="${PS1}\$ " This commit fixes this issues by adding an offset (+1) to the G.argv0_for_re_execing variable. This issue happens on our out-of-tree UML (use mode linux) with nommu configuration.
