2019-02-14lineedit: 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>
2019-02-14grep: 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.

2019-02-14ip link: Fix vlan proto, closes 8261 and 11638Bernhard Reutner-Fischer
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. Fix by using name/dev counterpart as fallback. The proto identifier 802.1Q was not recognized, just it's lowercase variant, fix that too. function old new delta do_add_or_delete 1275 1376 +101 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 101/0) Total: 101 bytes Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
