1.13.0 Changes of existing tools: - qetharp: Support IPv6 for query ARP cache for HiperSockets For HiperSockets (real and GuestLAN) in layer 3 mode, qetharp is now able to show IPv6 entries. These entries are only shown if qetharp is called with -6 or --ipv6 in conjunction with -q. - zfcpdbf: Adjust tool to 2.6.38 zfcp driver changes For the Linux kernel 2.6.38 the zfcp driver changed its tracing infrastructure. The zfcpdbf tool is updated to work with the new trace data. Note that the new tool will not be able to process zfcp traces from kernels older than 2.6.38. Bug Fixes: - cmsfs-fuse: * Allow opening of read-only disk images * Fix read error on fixed record length file in text mode * Fix read error on variable files ending with a null block * Fix off-by-one error for writing fixed length records * Don't update the last variable pointer for fixed files * Enlarge the file system name string * Delete old file if renaming to an existing file * Prevent segmentation fault if $HOME is undefined - hyptop: Fix man page typo ('r' = current weight) - hyptop: Prevent interactive mode on s390 line mode terminals To prevent hyptop starting in interactive mode on line mode terminals, the TERM variable is checked. If TERM is unset or set to "dumb" interactive mode is not allowed. - cpuplugd: Fix multiplication in rule expressions 1.12.0 Added new tool: - hyptop Changes of existing tools: - cio_ignore: Add new option -i / --is-ignored Add an option to the cio_ignore tool which can be used to determine if a device with a given ID is on the blacklist: # cio_ignore --is-ignored 0.0.0190 Device 0.0.0190 is ignored # cio_ignore --is-ignored 0.0.0009 Device 0.0.0009 is not ignored - cmsfs-fuse: Add support for configuration file Add a configuration file for automatic translation from EBCIDC to ASCII based on the file type. - tunedasd: Add new option -Q / --query_reserve The new option -Q / --query_reserve can be used to determine the reservation status of a device. - chreipl: Various enhancements * Add support to re-IPL from named saved systems (NSS) * Add support to specify additional kernel parameters for re-IPL * Add "auto target" support * Add support to re-IPL from device-mapper multipath devices - zgetdump: Add kdump support for --info option - zipl/zfcpdump_v2: Disable automatic activation of LUNs With Linux 2.6.37 all available ZFCP SCSI NPIV LUNs are automatically set online. For zfcpdump this has to be prevented because only the dump disk should be set online. To achieve this the zfcpdump application sets /sys/module/zfcp/parameters/allow_lun_scan to zero before setting the ZFCP device online. Bug Fixes: - dasdfmt: Fix buffer overrun in error message for option -b - cpuplugd: cmm_pages not set and restored correctly - lsluns: Fix LUN reporting for SAN volume controller (SVC) - lsluns: Uninitialized value on adapter offline An error message is presented stating that some values are not initialized while an operation is due. The program execution is not reflecting the offline adapter status. Account for offline adapter status and show an appropriate message - lsluns: Accept uppercase and lowercase hex digits - zgetdump: Add umount fallback for --umount option If the fusermount is not installed, zgetdump now tries the umount command as second choice to unmount a directory. - fdasd/dasdfmt: Fix format 7 label Backups of Linux on System z disks from z/OS do not work when the disk is not fully partitioned. The format 7 label written by fdasd and dasdfmt is incorrect. The extend for free space has one track less than required which is recognized as inconsistent vtoc state by z/OS tools. Fix libvtoc to write the format 7 label correctly. 1.11.0 Changes of existing tools: - cmsfs-fuse: Add write support With this support it is possible to add, delete, and modify CMS files under Linux. - zipl: Add support for automatic menus When the keyword 'defaultauto' is specified in the defaultboot section of a zipl.conf file, zipl will automatically build and install a boot menu including all IPL sections listed in the configuration file. - cpuplugd: Code cleanup for messages - all: Add gcov build support Extend the s390-tools build system to support gcov-based code coverage measurements. To use gcov on a compiled tool, perform these steps: 1. # make G=1 2. Run the tool 3. # gcov file.c (where file.c is the source code file for which code coverage data is requested) 4. Analyze gcov output written to file.c.gcov See the gcov man page for a description of the gcov output format. Note: gcov is only available for tools written in C and C++ Bug Fixes: - dumpconf: Redirect stdout/stderr to prevent "startpar" hangs - zfcpdbf: Rename --dates option Rename "--date" to "--dates" as documented in the man page. - chccwdev: Fix cio_settle usage when more than on device is changed The chccwdev tool can operate on lists of devices. If this feature is used, cio_settle is invoked too late. Use cio_settle prior to parsing the list of devices. - lsdasd: Fix return code of -h option - ziomon: Fix return codes for -h and -v options - ziomon: Replace deprecated "df -m" by "df -B 1M" ziomon uses GNU df with the option -m. This option is deprecated. It is replaced by the option "-B 1M". - zipl dump tools: Add retry logic for subchannel status In order to recover from failures like interface-control checks, we now retry the I/O, if the subchannel status is not equal to "0". - zipl: Check for maximum parmline size Parmlines which exceeds the maximum size are truncated during IPL which might cause problems. - zipl: Fix heap overflow when installing large menus Prevent zipl from writing menus with more than 50 entries to memory beyond the allocated heap buffer. - ttyrun: Fix argument parsing for upstart jobs ttyrun fails if you use the -e option in combination with a terminal that is specified using an absolute path. 1.10.0 Changes of existing tools: - znetconf: Add support for new CHPIDs OSX and OSM - chchp: Use /proc/cio_settle "cio_settle" ensures that all previously started CIO actions are handled. This feature is now used in chchp and ensures that after chchp returns, subsequent work of the requested action is completed e.g. (de)registration of devices. Bug Fixes: - ziomon: Fix the execution of stat <file> to follow symlinks Otherwise a false major:minor number is returned and the script fails to resolve the matching multipath-, SCSI-device combination. - znetconf: Fix -d|--driver option to work with latest versions of bash - cpuplugd: Fix cmm_min/max limit checks The cmm_min and cmm_max limits are not enforced correctly, when starting the daemon without the -V option or when cmm_pages is set manually below or above the limits. This patch makes the checks independent from the -V option and adds a check for cmm_pages beyond the limit. - cpuplugd: Set cpu_min to 1 by default With a cpu_min default value of 2 the "cpu ping pong" effect may still be visible with low system load, i.e. expensive CPU signaling may occur if the workload is spread on 2 under-worked CPUs. Therefore the default value of cpu_min is set to 1 now. - cpuplugd: Fix stack overwrite cpuplugd will terminate with "stack smashing" error on systems with more than 30 CPUs. The NULL termination of a read buffer will write beyond the buffer if a previous read() filled out the whole buffer. This is fixed by reading only maximum buffer size - 1 bytes. Also fixed some initialization errors discovered by valgrind. - cmsfs-fuse: Fix variable record file length ending with a null block If a variable record file ends with a null block, the whole block is counted. That results in a wrong file size since only the length as given in the variable header may be used from the null block. Correct the file size by calculating the used bytes from the record data of the last block. - cmsfs-fuse: Fix memory leak in freeing cached file data - iucvterm - iucvtty: Install signal handler for the interrupt signal An established IUCV terminal connection is not disconnected when iucvtty has been started in foreground and the user triggers an SIGINT. The parent process (iucvtty) exits but the child process keeps running. However, handle SIGINT and stop the child process. - iucvterm - iucvtty: Do not specify z/VM user IDs for the login program Login programs use -h to specify the host name of the originator. iucvtty passes the z/VM user ID for this option that might cause DNS timeouts if the target system cannot reach any DNS servers. - vmur: Revised man page and added vmur examples - ip_watcher - xcec-bridge: Fix multicast forwarding xcec-bridge was developed for the packet socket support of the qeth layer 3 driver. The code assumes there are no link level headers for incoming packets. The new qeth layer 3 driver has full packet socket support so xcec-bridge has to account the link level header. - zfcpdbf: Fix "Use of uninitialized value" and output issues, add devno and timestamp to output of "status read" and remove output of LS field for ELS requests; it was wrong, and newer dbf does not have this redundant field. - qethconf: Fix "ipa list" function to display devices with subchannel set != 0 - vmconvert: Fix dump conversion problem for z/VM guests with DCSSes For VMDUMPs of z/VM guests with DCSSes vmconvert used the wrong storage size. - chccwdev: Fix --attribute option - chccwdev: Print message if no driver is attached to a device 1.9.0 Added new tools: - cmsfs-fuse - ttyrun - lsmem/chmem Changes of existing tools: - zgetdump: Add dump conversion and mount support The zgetdump tool can be used now for dump format conversion.It can read ELF, s390, and LKCD and write ELF and s390 format dumps. A mount option based on "fuse" is added to zgetdump that allows dumps to be converted in memory on the fly without the need of copying them. The following two options are added to zgetdump: * fmt: Specify output dump format (elf or s390) * mount: Mount dump instead of copying it to standard output - zgetdump: Remove multi-volume tape dump support The capacity of todays tape cartridges is big enough for dumping large systems. Therefore multi-volume tape dump support is no longer needed. - lsqeth: Add new qeth attribute "sniffer" - chccwdev, cio_ignore: Use /proc/cio_settle "cio_settle" ensures that all previously started CIO actions are handled. This feature is used now in chccwdev and cio_ignore and has the following effects: * chccwdev: Devices can be attached and set online afterwards with chccwdev without the need of a delay between the commands. * cio_ignore: After cio_ignore returns it is now ensured that the requested action is completed. - zfcpdump_v2/vmconvert: Add CPU lowcore pointers to asm dump header By adding the CPU lowcore pointers to the dump header we now can access the CPU registers in dumps without needing the System.map symbol information. Bug Fixes: - ziomon: Allow ziorep_config to be installed to different directories The path for ziorep_config has been hard-coded to "/sbin/ziorep_config" and it was checked to detect install errors. However distributions may install these files in varying directories. With this patch this is possible now, because the hardcoded path is no longer necessary. ziorep_config now has to be installed to a directory that is in the PATH variable of the caller. - ziomon: Fix problem with long multipath device names When tracing multipath devices with long names, e.g. /dev/mapper/360050768018f8267c800000000000008, parsing of the 'df' command output can break and result in syntax error messages on the command line. - ziomon: Fix problem with multipath command output Some versions of the multipath command use characters that can break parsing of its output, ultimately leading to error messages like: ziomon: Number of LUNs does not match number of devices: 12 devices and 10 LUNs - zipl/zfcpdump: Use "cgroup_disable=memory" kernel parameter The zfcpdump kernel has to run within a 32 MB limit. When using "memory cgroups" about 2.6 MB are allocated, which can lead to "out of memory" kernel panic during SCSI dump. For zfcpdump we do not need "memory cgroups". Therefore it is disabled via the zfcpdump kernel parameter line. - zipl: Fix tape IPL failure IPL from tape after prepared by zipl stops with a disabled wait PSW. zipl did not provide a reasonable address of an initrd to the loader. - lsdasd: Add missing description of option -b to man page - lsqeth: Determine sysfs mount point using /proc/mounts - lsqeth: Clear print array for every device displayed - lsluns: Move lsluns from /sbin to /usr/sbin The lsluns tool uses perl that normally is installed under "/usr/bin". According to LSB we also have to install the lsluns tool to "/usr". - iucvterm: Allow non-alphanumeric characters when parsing group names - zfcpdump_v2: Use direct-IO for writing dumps Using direct-IO for zfcpdump has two major advantages compared to normal IO that uses the Linux page cache: * On recent Linux kernel versions it is faster on small systems. * Because no page cache is used, less memory is consumed. 1.8.4 Added new tools: - 60-readahead.rules: udev rules to set increased "default max readahead" The current "default max readahead" defined by the kernel is too small for s390. Add udev rule to set a better default value. This will increase sequential read performance up to 40%. Changes of existing tools: - zipl: Improve I/O error recovery during IPL Change the boot loader code to handle temporary path errors and link flapping during IPL. - zipl: Remove DEFAULT_RAMDISK_ADDRESS Using the default value has been replaced by calculating the address dependent on the image size. - lsqeth: Introduce "lay'2" column for "lsqeth -p" Add new qeth attribute "isolation". - qethconf: Indicate command failure and show message list When qethconf detects a bad exit status of its issued echo command, an error message is presented to the user. In addition possible reasons for command failure can be listed with "qethconf list_msg". - dumpconf: Prevent re-IPL loop for dump on panic A new DELAY_MINUTES keyword is introduced in the dumpconf configuration file. The keyword delays the activation of dumpconf to prevent potential re-IPL loops. - dbginfo: Add new attributes Bug Fixes: - cpuplugd: Fix file handling in get_cmmpages_size() - fdasd, dasdinfo, tunedasd: Fix handling of read-only devices A as long as a tool does not require write access do a block device, it should open the device in read-only mode. Otherwise opening the device may fail, and usability of the tool on read-only devices is unnecessarily restricted. - fdasd: Fix auto mode behavior Fix the misbehavior of fdasd in case the -a or -i option is specified and the label block is broken. Previously it asked interactively for a new label. Now it exits with an error message. - dasdview, fdasd: Fix floating point error for unformatted devices When executed on an unformatted device the tools dasdview and fdasd will end with an floating point exception error. The reason for the error lies in the fact that we cannot rely on the HDIO_GETGEO ioctl to report a correct number of cylinders and so we compute the number of cylinders from the device size. However, for unformatted devices the device size is zero and thus our computation ends with a floating point exception. To solve this issue read the correct number of cylinders from the DASD device characteristics, which can be found in the data returned by the BIODASDINFO ioctl. - libvtoc: Fix string overflow in vtoc_volume_label_init() Originally it tries to copy a 84B string into 4B field and reset also the other fields through the overflow. This doesn't work with recent GCC versions. - mon_statd: Improve init script * stop: Do not print error messages if a daemon is not configured. * start: Do not load module if no daemon is configured. * Remove useless newlines. - lscss: Fix uppercase conversion (appeared with -u option) - lstape: Help function returns 1, although it was successful Changed exit status of "lstape --help" from 1 to 0. - znetconf: Index into chpidtype lookup table must be hex Network subchannels with CHPID type containing non-decimal digits, i.e. a-f, cause lsznet.raw errors. The value of the sysfs attribute "type" of a CHPID is hex, but the lookup table index in the bash script must be decimal. To solve the problem, we now interpret "type" as hex number when used as lookup table index. - chreipl: Fix SIGSEGV in "chreipl node" When calling "chreipl node /dev/dasdxy" chreipl crashes with SIGSEGV. The problem is a missing check in get_ccw_devno_old_sysfs(). Besides of that at two places strncpy() was called with the wrong size. - chshut: Disable panic action The panic action should be configured using the dumpconf service. Therefore we disable the possibility to configure it with chshut in order to avoid conflicts. - lsreipl: Add missing NSS support - vmconvert: Ensure null termination of progress bar string The progress bar shows control characters at end of line, because one variable responsible for the progress bar has not been initialized. We now initialize this variable correctly. - vmconvert, zfcpdump_v2: Set correct LKCD end marker flag - zfcpdump_v2: Ignore failure of modprobe It is possible that all modules are built-in the zfcpdump kernel. Therefore modprobe of those modules will fail and we must not check the return value. - ziomon: ziorep_traffic/utilization return 1 when called with -h & -v These two tools return 1 when -h or -v are used as arguments. Changed the return code in these cases to 0. - zipl: zfcp dump partition error The info structure was used after it was freed. This leads to wrong partition information on the zfcp dump device. Therefore SCSI dumps may fail. To fix this, we free the info structure after last usage.
