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.
