2019-02-04lineedit: fix SEGV in isk, hexedit, ed, closes 11661Denys Vlasenko
fdisk, hexedit and ed calls read_line_edit in libbb/lineedit.c with NULL as first argument. On line 2373 of lineedit.c of busybox version 1.29.3, state->hist_file is referenced without checking the state->flag. This causes segmentation fault on fdisk, hexedit and ed on ARM Cortex-A9. It somehow works on x86_64. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2019-01-29grep: short-circuit -v to bail out on first matchAri Sundholm
A small optimization. There is no need to try matching the current input line against any further patterns if a match was already found and -v is specified. function old new delta grep_file 1463 1440 -23 Signed-off-by: Ari Sundholm <ari@tuxera.com> Signed-off-by: Niko Vähäsarja <niko@tuxera.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2019-01-29grep: fix -x -v with certain pattern ordersAri Sundholm
We found out that busybox -x -v is a bit broken: ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -e 'aa.*' -e '.*bb.*' aa bb cc ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -v -e 'aa.*' -e '.*bb.*' ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -e '.*aa.*' -e 'bb.*' aa bb cc ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -v -e '.*aa.*' -e 'bb.*' aa bb cc Last one is wrong. This patch fixes the issue by making sure that the variable 'found' never makes a transition from 1 to 0, as this would mean that grep previously found a match on this input line.

The proto has to be passed in network byte-order. While at it allow for ip link add link eth0 name eth0.2.24 type vlan proto 802.1ad id 24 ip link del link eth0 name eth0.2.24 type vlan proto 802.1ad id 24 The del was lacking a dev_str and thus errored out.
