From: Matthias Schiffer Date: Thu, 23 Jul 2015 01:31:05 +0200 Subject: ar71xx: fix wndr3700_board_detect for some NETGEAR WNDR3700v2 There are a few NETGEAR devices which don't terminate the model name in the ART with a NUL byte, at least some NETGEAR WNDR3700v2. The current awk expression doesn't match 0xFF bytes, so AR71XX_MODEL contains lots of trailing 0xFF garbage in this case. Fix this by matching for the first non-printable character and explicitly setting LC_CTYPE=C (probably not strictly necessary on OpenWrt, but will definitely work like this, even when awk supports locales and LANG is set). diff --git a/target/linux/ar71xx/base-files/lib/ar71xx.sh b/target/linux/ar71xx/base-files/lib/ar71xx.sh index d79776b..6ba40aa 100755 --- a/target/linux/ar71xx/base-files/lib/ar71xx.sh +++ b/target/linux/ar71xx/base-files/lib/ar71xx.sh @@ -38,7 +38,7 @@ wndr3700_board_detect() { ;; "33373031") # Use awk to remove everything after the first zero byte - model="$(ar71xx_get_mtd_offset_size_format art 41 32 %c | awk 'BEGIN{FS="[[:cntrl:]]"} {print $1; exit}')" + model="$(ar71xx_get_mtd_offset_size_format art 41 32 %c | LC_CTYPE=C awk -v 'FS=[^[:print:]]' '{print $1; exit}')" case $model in $'\xff'*) if [ "${model:24:1}" = 'N' ]; then
