File s390-tools-sles15sp3-04-dbginfo.sh-code-rework.patch of Package s390-tools.27266
Subject: [PATCH] [BZ 195579] dbginfo.sh: code rework From: Joern Siglen <siglen@de.ibm.com> Description: dbginfo.sh: stabilzation of data collection Symptom: o script hangup possible on single commands o missing data collection on error o overwrite of buffers by diag commands Problem: hangup and lost of data collection Solution: rework code regarding o add timeout function o remove probelmatic commands o include handling improvements Reproduction: - Upstream-ID: 01551f98d5e97c383d82857ad0aac5a0294f0619 Problem-ID: 195579 Upstream-Description: dbginfo.sh: code rework - adding new print function for simpler output customizing - consolidate some output files - sync structures and use of checks - some formatting updates Signed-off-by: Joern Siglen <siglen@de.ibm.com> Signed-off-by: Jan Hoeppner <hoeppner@linux.ibm.com> Signed-off-by: Joern Siglen <siglen@de.ibm.com> --- s390-tools-service.orig/scripts/dbginfo.sh +++ s390-tools-service/scripts/dbginfo.sh @@ -14,8 +14,9 @@ export LC_ALL ######################################## # Global used variables -readonly SCRIPTNAME="${0##*/}" # general name of this script +readonly SCRIPTNAME="${0##*/}" # general name of this script # +readonly DATETIME="$(date +%Y-%m-%d-%H-%M-%S 2>/dev/null)" readonly DOCKER=$(if which docker >/dev/null 2>&1; then echo "YES"; else echo "NO"; fi) readonly HW="$(uname -i 2>/dev/null)" # retrieve and split kernel version @@ -30,20 +31,25 @@ readonly LOCKFILE="/tmp/${SCRIPTNAME}.lo # check limits for logfiles like /var/log/messages readonly LOG_FILE_SIZE_CHECK=50 # max logfile size in MB readonly LOG_FILE_AGE_CHECK=7 # age in days to include for size checking +# Mount point of the debug file system +readonly MOUNT_POINT_DEBUGFS="/sys/kernel/debug" # distro info readonly OSPRETTY="$(cat /etc/os* 2>/dev/null | grep -m1 PRETTY_NAME | sed 's/\"//g')" readonly OS_NAME="${OSPRETTY##*=}" # The processor ID for the first processor readonly PROCESSORID="$(grep -E ".*processor 0:.*" /proc/cpuinfo | \ -
