From: Ben Greear <gree...@candelatech.com> This first release is all about checking for ath10k firmware crashes. Could be extended later for other modules/bugs/etc.
Signed-off-by: Ben Greear <gree...@candelatech.com> --- v2: Add comments about this being for ath10k firmware Change name to 'ct-bugcheck' since this is mostly about ct ath10k firmware at this point. package/utils/ct-bugcheck/Makefile | 52 ++++++++++++ package/utils/ct-bugcheck/src/bugcheck.initd | 16 ++++ package/utils/ct-bugcheck/src/bugcheck.sh | 115 +++++++++++++++++++++++++++ package/utils/ct-bugcheck/src/bugchecker.sh | 29 +++++++ 4 files changed, 212 insertions(+) create mode 100644 package/utils/ct-bugcheck/Makefile create mode 100644 package/utils/ct-bugcheck/src/bugcheck.initd create mode 100755 package/utils/ct-bugcheck/src/bugcheck.sh create mode 100755 package/utils/ct-bugcheck/src/bugchecker.sh diff --git a/package/utils/ct-bugcheck/Makefile b/package/utils/ct-bugcheck/Makefile new file mode 100644 index 0000000..5deb1e0 --- /dev/null +++ b/package/utils/ct-bugcheck/Makefile @@ -0,0 +1,52 @@ +# +# Copyright (C) 2016 OpenWrt.org +# +# This is free software, licensed under the GNU General Public License v2. +# See /LICENSE for more information. +# + +include $(TOPDIR)/rules.mk +include $(INCLUDE_DIR)/kernel.mk + +PKG_NAME:=ct-bugcheck +PKG_RELEASE:=2016-07-21 + +include $(INCLUDE_DIR)/package.mk + +define Package/ct-bugcheck + SECTION:=utils + CATEGORY:=Utilities + TITLE:=Bug checking and reporting utility + VERSION:=$(PKG_RELEASE) + MAINTAINER:=Ben Greear <gree...@candelatech.com> +endef + +define Package/ct-bugcheck/description + Scripts to check for bugs (like firmware crashes) and package them for reporting. + Currently this script only checks for ath10k firmware crashes. + Once installed, you can enable this tool by creating a file called + /etc/config/bugcheck with the following contents: + DO_BUGCHECK=1 + export DO_BUGCHECK + +endef + +define Build/Prepare + $(CP) src/bugcheck.sh $(PKG_BUILD_DIR)/ + $(CP) src/bugchecker.sh $(PKG_BUILD_DIR)/ + $(CP) src/bugcheck.initd $(PKG_BUILD_DIR)/ +endef + +define Build/Compile + true +endef + +define Package/ct-bugcheck/install + $(INSTALL_DIR) $(1)/usr/bin + $(INSTALL_DIR) $(1)/etc/init.d + $(INSTALL_BIN) $(PKG_BUILD_DIR)/bugcheck.sh $(1)/usr/bin/ + $(INSTALL_BIN) $(PKG_BUILD_DIR)/bugchecker.sh $(1)/usr/bin/ + $(INSTALL_BIN) $(PKG_BUILD_DIR)/bugcheck.initd $(1)/etc/init.d/bugcheck +endef + +$(eval $(call BuildPackage,ct-bugcheck)) diff --git a/package/utils/ct-bugcheck/src/bugcheck.initd b/package/utils/ct-bugcheck/src/bugcheck.initd new file mode 100644 index 0000000..b97a415 --- /dev/null +++ b/package/utils/ct-bugcheck/src/bugcheck.initd @@ -0,0 +1,16 @@ +#!/bin/sh /etc/rc.common +# Copyright (C) 2016 OpenWrt.org + +START=99 + +USE_PROCD=1 +PROG=/usr/bin/bugchecker.sh + +# To actually make bugchecker.sh run, see comments +# at top of its file. + +start_service () { + procd_open_instance + procd_set_param command "$PROG" + procd_close_instance +} diff --git a/package/utils/ct-bugcheck/src/bugcheck.sh b/package/utils/ct-bugcheck/src/bugcheck.sh new file mode 100755 index 0000000..85f70c5 --- /dev/null +++ b/package/utils/ct-bugcheck/src/bugcheck.sh @@ -0,0 +1,115 @@ +#!/bin/sh + +# Check for ath10k (and maybe other) bugs, package them up, +# and let user know what to do with them. + +TMPLOC=/tmp +CRASHDIR=$TMPLOC/bugcheck +FOUND_BUG=0 + +# set -x + +bugcheck_generic() +{ + echo "LEDE crashlog report" > $CRASHDIR/info.txt + date >> $CRASHDIR/info.txt + echo >> $CRASHDIR/info.txt + echo "uname" >> $CRASHDIR/info.txt + uname -a >> $CRASHDIR/info.txt + echo >> $CRASHDIR/info.txt + echo "os-release" >> $CRASHDIR/info.txt + cat /etc/os-release >> $CRASHDIR/info.txt + echo >> $CRASHDIR/info.txt + echo "os-release" >> $CRASHDIR/info.txt + cat /etc/os-release >> $CRASHDIR/info.txt + echo >> $CRASHDIR/info.txt + echo "dmesg output" >> $CRASHDIR/info.txt + dmesg >> $CRASHDIR/info.txt + if [ -x /usr/bin/lspci ] + then + echo >> $CRASHDIR/info.txt + echo "lspci" >> $CRASHDIR/info.txt + lspci >> $CRASHDIR/info.txt + fi + echo >> $CRASHDIR/info.txt + echo "cpuinfo" >> $CRASHDIR/info.txt + cat /proc/cpuinfo >> $CRASHDIR/info.txt + echo >> $CRASHDIR/info.txt + echo "meminfo" >> $CRASHDIR/info.txt + cat /proc/cpuinfo >> $CRASHDIR/info.txt + echo >> $CRASHDIR/info.txt + echo "cmdline" >> $CRASHDIR/info.txt + cat /proc/cmdline >> $CRASHDIR/info.txt + echo >> $CRASHDIR/info.txt + echo "lsmod" >> $CRASHDIR/info.txt + lsmod >> $CRASHDIR/info.txt +} + +roll_crashes() +{ + #
