  Hi,
  capnproto 0.8.0-2ubuntu1 fails on ppc64el : 
  
https://launchpad.net/ubuntu/+source/capnproto/0.8.0-2ubuntu1/+build/23090234/+files/buildlog_ubuntu-jammy-ppc64el.capnproto_0.8.0-2ubuntu1_BUILDING.txt.gz

  Lowering optimization (O3->O2) level makes the failing test pass, for
  instance adding 

  export DEB_CXXFLAGS_MAINT_APPEND=-O1
  export DEB_CXXFLAGS_MAINT_STRIP=-O3

  in debian/rules.

  For the time being that can be the way to go as 0.9.1-2 from Debian 
Experimental
  builds fine on Jammy by default with O3.

  Description:   zlib: inflateSyncPoint() returns an incorrect result on z15
  Symptom:   Certain rsync builds fail with "error in rsync protocol data
 stream" on z15.
  Problem:   inflateSyncPoint() does not take into account the hardware
 compression state and returns an incorrect result.
  Solution:  Make inflateSyncPoint() fail if the hardware compression is on.
 The hardware does not provide enough information in order to
 implement this function.
  Reproduction:  z15 only: printf 1 >1 && rsync -z 1 2

  Pull request (https://github.com/madler/zlib/pull/410) and tagged
  https://github.com/iii-i/zlib/tree/dfltcc-20200511.

  The new code contains the following improvements:
  * Added support for switching between software and hardware compression.
  * Added --dfltcc configure flag (the old way of building it still works).

  Switching between software and hardware compression is not simply a
  nice-to-have feature, but is actually required by Java - that's why we
  are requesting an update.

[Andrew Cloke]

  tc filter show tcp_flags wrong mask value

Status in The Ubuntu-power-systems project:

Status in iproute2 source package in Bionic:

Bug description:
  [SRU Justification]

  Impact: The tc command does not show the correct values for tcp_flags
  (and ip_tos) on filter rules. This might break other scripts parsing
  that output but at least confuses users.

  Fix: Backport of "tc: fix bugs for tcp_flags and ip_attr hex output"
  from upstream iproute2.

  Testcase:
  tc qdisc add dev lo ingress
  tc filter add dev lo parent : prio 3 proto ip flower ip_tos 0x8/32
  tc filter add dev lo parent : prio 5 proto ip flower ip_proto tcp \
   tcp_flags 0x909/f00

  tc filter show dev lo parent :

  filter protocol ip pref 3 flower chain 0
  filter protocol ip pref 3 flower chain 0 handle 0x1
    eth_type ipv4
    ip_tos a9606c10 <-- bad, should be 0x8/32
    not_in_hw
  filter protocol ip pref 5 flower chain 0
  filter protocol ip pref 5 flower chain 0 handle 0x1
    eth_type ipv4
    ip_proto tcp
    tcp_flags 909909 <-- bad, should be 0x909/f00
    not_in_hw

  Note that the ip_tos value in the -j[son] output is correct, while the 
tcp_flags value is
  is incorrect in both cases.

  Risk of Regression:
  Low: Usually scripts would use the json output and that has at least the ip 
output correct. And the values shown in the bad case seem to be little useful. 
So it seems unlikely anybody relied on them. But cannot completely be ruled out.

  ---Problem Description---
  Problem Descriptions
  "tc" utility does not show correct TC rule's tcp_flags mask correctly in 
current "iproute2" package shipped on Genesis.
  # dpkg -l |grep iproute2
  ii  iproute2  4.15.0-2ubuntu1  ppc64el  networking and traffic control 
tools

  ---Steps to Reproduce---
   Steps to reproduce the problem:
  1) Add a tc rule to the testing VF (i.e. p0v2_r):
  # tc filter add dev p0v2 protocol ip parent : pref 5 chain 1 handle 0x1  
flower src_mac 00:00:00:00:4e:2f/00:00:00:ff:ff:ff ip_proto tcp tcp_flags 2  
skip_sw action mirred egress redirect dev p0v0_r

  2) Validate the added TC rule:
  # tc filter show dev p0v2_r root
  filter protocol ip pref 5 flower chain 1
  filter protocol ip pref 5 flower chain 1 handle 0x1
    src_mac 00:00:00:00:4e:2f/00:00:00:ff:ff:ff
    eth_type ipv4
    ip_proto tcp
    tcp_flags 22   /* <--- Wrong */
    skip_sw
    in_hw
  action order 1: mirred (Egress Redirect to device p0v0_r) stolen

  3) If we add the tcp_flags using explicit mask 0x7:
  # tc filter add dev p0v2 protocol ip parent : pref 5 chain 1 handle 0x1  
flower src_mac 00:00:00:00:4e:2f/00:00:00:ff:ff:ff ip_proto tcp tcp_flags 0x2/7 
 skip_sw action mirred egress redirect dev p0v0_r

  After that, using "tc filter show dev p0v2_r root" to verify, we still
  see the same output (tcp_flags 22) as shown in 2) above, which is
  wrong.

  If you install Ubuntu onto USB storage behind a Platform USB host controller, 
it will not be able to boot because the generated initramfs will not include 
the host controller driver.

  [Test Case]
  Install to a USB stick attached to platform USB controller and reboot. 
Booting will fail because it will be unable to find the root file system.

  [Regression Risk]
  Driver is only loaded when system requires ehci-platform, minimizing the 
impact to all other systems.

[Andrew Cloke]

Thanks to Dimitri for pointing out that the comment #2 is not designed
to actually SET the HW Clock from the host, but to ALLOW the HW Clock to
be set with /sbin/hwclock. I had completely missed this.

Next step is to try the sequence described in comment #2 (on the BMC and
also on the host), and then retry using /sbin/hwclock on the host to
change the HW clock time.

Bug description:
  Calculate the checksum of data that is 16 byte aligned and a multiple
  of  16 bytes.

  The first step is to reduce it to 1024 bits. We do this in 8 parallel
   chunks in order to mask the latency of the vpmsum instructions. If we
   have more than 32 kB of data to checksum we repeat this step multiple
   times, passing in the previous 1024 bits.

   The next step is to reduce the 1024 bits to 64 bits. This step adds
   32 bits of 0s to the end - this matches what a CRC does. We just
   calculate constants that land the data in this 32 bits.

   We then use fixed point Barrett reduction to compute a mod n over GF(2)
   for n = CRC using POWER8 instructions. We use x = 32.

[Touch-packages] [Bug 1837443] Re: [Power9][Witherspoon dd2.3] unable to set hwclock

[Andrew Cloke]

I believe /sbin/hwclock is the default tool for manually setting the
hwclock in Linux. I’m nervous that higher level workloads may depend on
the correct functioning of the /sbin/hwclock tool for their successful
operation.

The /sbin/hwclock tool is shipped with the util-linux package.

Adding util-linux as impacted and assigning to Foundations team to
comment on whether the /sbin/hwclock tool not operating on witherspoon
is a serious issue or not.

  initramfs created with MODULES=dep or kdump initrd won't boot a system with

  [Test case]
  Systems with nvme multipath were able to boot with the created initramfs. 
Also tested on systems with non-multipath nvme, and non nvme systems.

  In order to verify the fix, one needs to change MODULES option to dep
  on /etc/initramfs-tools/initramfs.conf, recreate initramfs and reboot,
  check the system has booted fine. That should not break on systems
  with non nvme disks or systems with non multipath nvme systems, and
  that should now work on multipath nvme systems.

  A system could fail to boot because the generated initramfs was broken. The 
code should just add modules, which is safer than removing modules or doing any 
other changes. In any case, it was tested to boot on multipath nvme, non 
multipath nvme and non nvme systems.

Bug description:
  [Impact]
  GDB fails to debug ARM64 vmlinux debug image with proc/kcore information. For 
example it is unable to print values of variables like 'jiffies_64'.

  [Test]
  # gdb /usr/lib/debug/boot/vmlinux-4.18.0-20-generic  /proc/kcore

  Core was generated by `BOOT_IMAGE=/boot/vmlinuz-4.18.0-20-generic

  #0  0x in ?? ()
  (gdb) p jiffies_64
  Cannot access memory at address 0x09616980
  (gdb)

  [Fix]
  This issue was fixed upstream (git://sourceware.org/git/binutils-gdb.git) by 
the following patch:
  8727de56b0  Fix tagged pointer support

  [Regression Potential]
  The risk of regression after applying this patch could be to architectures 
other than ARM64 due to changes to gdb/util.c. Please see comment #2 where I 
have tested the PPA package on a ppc64el system and found it does not introduce 
any regressions.

[Touch-packages] [Bug 1778844] Re: nvme multipath does not report path relationships

[Andrew Cloke]

Thanks for the verification in comment #67. From the comment, I believe this 
was verified with bionic. Could you also verify with Cosmic and post your 
results?
Thanks.

Bug description:
  [Impact]
  initramfs created with MODULES=dep or kdump initrd won't boot a system with 
root filesystem on a multipath nvme.

  [Test case]
  Systems with nvme multipath were able to boot with the created initramfs. 
Also tested on systems with non-multipath nvme, and non nvme systems.

  In order to verify the fix, one needs to change MODULES option to dep
  on /etc/initramfs-tools/initramfs.conf, recreate initramfs and reboot,
  check the system has booted fine. That should not break on systems
  with non nvme disks or systems with non multipath nvme systems, and
  that should now work on multipath nvme systems.

  sed -i /MODULES=/s,=.*,=dep, /etc/initramfs-tools/initramfs.conf
  update-initramfs -u -k all
  reboot

  [Regression potential]
  A system could fail to boot because the generated initramfs was broken. The 
code should just add modules, which is safer than removing modules or doing any 
other changes. In any case, it was tested to boot on multipath nvme, non 
multipath nvme and non nvme systems.

Note that this is likely to require an MIR

tools for 20.04.

We will investigate and update this bug shortly.

I notice that this issue was raised some time ago. Is there any
additional information you can share as to recent specific use cases or
scenarios?

Thanks.

Bug description:
  Calculate the checksum of data that is 16 byte aligned and a multiple
  of  16 bytes.

  The first step is to reduce it to 1024 bits. We do this in 8 parallel
   chunks in order to mask the latency of the vpmsum instructions. If we
   have more than 32 kB of data to checksum we repeat this step multiple
   times, passing in the previous 1024 bits.

   The next step is to reduce the 1024 bits to 64 bits. This step adds
   32 bits of 0s to the end - this matches what a CRC does. We just
   calculate constants that land the data in this 32 bits.

   We then use fixed point Barrett reduction to compute a mod n over GF(2)
   for n = CRC using POWER8 instructions. We use x = 32.

  nvme multipath does not report path relationships

Bug description:
  [Impact]
  initramfs created with MODULES=dep or kdump initrd won't boot a system with 
root filesystem on a multipath nvme.

  [Test case]
  Systems with nvme multipath were able to boot with the created initramfs. 
Also tested on systems with non-multipath nvme, and non nvme systems.

  In order to verify the fix, one needs to change MODULES option to dep
  on /etc/initramfs-tools/initramfs.conf, recreate initramfs and reboot,
  check the system has booted fine. That should not break on systems
  with non nvme disks or systems with non multipath nvme systems, and
  that should now work on multipath nvme systems.

  sed -i /MODULES=/s,=.*,=dep, /etc/initramfs-tools/initramfs.conf
  update-initramfs -u -k all
  reboot

  [Regression potential]
  A system could fail to boot because the generated initramfs was broken. The 
code should just add modules, which is safer than removing modules or doing any 
other changes. In any case, it was tested to boot on multipath nvme, non 
multipath nvme and non nvme systems.

Bug description:
  [Impact]
  initramfs created with MODULES=dep or kdump initrd won't boot a system with 
root filesystem on a multipath nvme.

  [Test case]
  Systems with nvme multipath were able to boot with the created initramfs. 
Also tested on systems with non-multipath nvme, and non nvme systems.

  [Regression potential]
  A system could fail to boot because the generated initramfs was broken. The 
code should just add modules, which is safer than removing modules or doing any 
other changes. In any case, it was tested to boot on multipath nvme, non 
multipath nvme and non nvme systems.

  ISST-LTE: KVM:UBUNTU1804: BostonLC: fdisk -l shows the conflicting
  partitions name for the mpath

Status in The Ubuntu-power-systems project:

Bug description:
  
  [Impact]
  Any user of Ubuntu on multipath, where the default path separator has been 
changed to something else. This possibly affects other scenarios where the 
partition separator can be changed.

  [Test case]
  1) Install Ubuntu on multipath system
  2) Change /etc/multipath.conf to set "path_separator" to "" or "p".
  3) Reboot
  4) Run 'sudo fdisk -l /dev/mapper/mpathX', to display a device's partitions 
where the path separator would be visible.

  
  [Regression potential]
  Minimal. This only affects display. Default separator on Ubuntu remains 
"-part". If the separator is not one of "", "p", or "-part", then "-part" would 
be used, as is already the case.

  We have the Ubuntu1804 installed on our BostonLC system. Create a SAN via the 
Emulex adapter to have the mpath disk.
  Running the fdisk -l and ls -l showing the conflict name for the mpath.

  ISST-LTE: KVM:UBUNTU1804: BostonLC: fdisk -l shows the conflicting
  partitions name for the mpath

Bug description:
  
  [Impact]
  Any user of Ubuntu on multipath, where the default path separator has been 
changed to something else. This possibly affects other scenarios where the 
partition separator can be changed.

  [Test case]
  1) Install Ubuntu on multipath system
  2) Change /etc/multipath.conf to set "path_separator" to "" or "p".
  3) Reboot
  4) Run 'sudo fdisk -l /dev/mapper/mpathX', to display a device's partitions 
where the path separator would be visible.

  
  [Regression potential]
  Minimal. This only affects display. Default separator on Ubuntu remains 
"-part". If the separator is not one of "", "p", or "-part", then "-part" would 
be used, as is already the case.

[Touch-packages] [Bug 1776626] Re: [18.10 FEAT] Support 4k sectors for fast clear key dm-crypt - crypttab part

  [18.10 FEAT] Support 4k sectors for fast clear key dm-crypt - crypttab
  part

Status in Ubuntu on IBM z Systems:
  In Progress
Status in cryptsetup package in Ubuntu:
  Fix Released
Status in systemd package in Ubuntu:
  Fix Released
Status in cryptsetup source package in Bionic:
  New
Status in systemd source package in Bionic:

Bug description:
  [Impact]

   * cryptsetup in bionic supports creating luks volumes with a non-
  standard sector-size option, and thus this option also needs to be
  used when activating the LUKS volumes. Add sector-size= option support
  to /etc/crypttab.

  [Test Case]

   * Create a plain LUKS volume with sector-size 4096
   * Specify sector-size=4096 option in /etc/crypttab
   * reload systemd, start systemd-cryptsetup@.service for that volume
   * check the journal, to ensure that `sector-size` option was recognized and 
is active. (i.e. there is not error messages about unrecognized option 
`sector-size` from systemd-cryptsetup)

  [Regression Potential]

   * This is an optional argument, not used by default. Currently custom
  sector-size crypttab does not work correctly, and thus cannot regress.

  [Other Info]
   
   * Original bug report

  Support fast clear key dm-crypt with 4k support

  Extend /etc/crypttab  to enable 4k sector support in plain mode

  The proposed enhancements are posted on github, see
   https://github.com/systemd/systemd/issues/8881

  when i enable  in /etc/sysctl.conf it works  . i append below value in  
sysctl.conf

  echo "kernel.sysrq = 1" >> /etc/sysctl.conf

  I think this is should be enable by default  in ubuntu 18.10 as
  earlier ubuntu distro it has , not sure why it got removed as kdump
  mechanism require this .

Status in Ubuntu on IBM z Systems:

Status in binutils package in Ubuntu:
  Fix Released
Status in binutils source package in Xenial:
  Fix Released

Bug description:
  [Impact]

   * as segfaults, instead of exiting gracefully, when one specifies 
unsupported arch option (ie. one from future - cause xenial did not support z14)
   * this is bad, as detection fails around supported march options - as if 
binutils are completely broken, rather than just not supporting this or that 
CPU level of optimisations.

  [Test Case]

  Bad result:
   $ as -march=foo
  Segmentation fault

  Expected result:
  # as -march=foo
  Assembler messages:
  Error: invalid switch -march=foo
  Error: unrecognized option -march=foo

  [Regression Potential]

   * The result is still a failure condition, but with a proper exit
  code and standard error messages, rather than an unexplainable generic
  segfault.

  [Other Info]
   
   * Original bug report

  The GNU assembler segfaults with an invalid -march= option

  Userspace tool common name: as

  The userspace tool has the following bit modes: 64

  Userspace tool obtained from project website:  na

  *Additional Instructions for n/a:
  -Attach ltrace and strace of userspace application.

  The problem is not critical since usually 'as' is invoked through the
  gcc driver which itself errors out for wrong -march= options. It will
  only be a problem if somebody builds a more recent GCC from source and
  uses an -march= option for a machine not supported by the default
  binutils.

  Please consider integrating the attached patch into 16.04 binutils.

  The problem has been fixed in later binutils already. Ubuntu 18.04
  does not appear to be affected.

  I talked to Matthias Klose already, and he is aware of this request.

  lscpu fails to list CPU max and min frequencies if some CPUs are guarded.

  [Regression potential]
  Isolated change to lscpu min/max CPU frequency output, so the worst that 
could happen is that it fails to work elsewhere.

  [Test case]
  1. Clone https://github.com/open-power/op-test-framework
  2. Run this command to GUARD the cpu.
  ./op-test --bmc-type FSP --bmc-ip $FSPIP --bmc-username dev --bmc-password 
FipSdev --host-ip $HOSTIP --host-user root --host-password passw0rd --ffdcdir 
test-reports/ --run testcases.OpTestHMIHandling.MalfunctionAlert
  3. Repeat again, so that multiple CPUs are guarded.
  4. Run lscpu
  5. Observe that no CPU frequencies are displayed:
  CPU max MHz: (null)
  CPU min MHz: (null)
  6. Install util-linux from -proposed.
  7. Run lscpu again
  8. Observe that max and min CPU frequencies are correctly displayed.

[Touch-packages] [Bug 1719579] Re: [Ubuntu 18.04] [libvirt] virsh restore fails from state file saved in /var/tmp folder using virsh save

[Andrew Cloke]

>From comment #22: "Distro team, Is there any update based on the
previous update we posted. ?"

I'm afraid this bug report is now a little complex and involved, and it
is now marked as "Fix Released" in Launchpad.

Could you please be specific about the comment or question that you
require more information about? Alternatively, it may be best to raise a
new bug report.

Bug description:
  Hi,
  while debugging bug 1678322 I was running along apparmor issues.
  Thanks to jjohansen we debugged some of it and eventually I was asked to 
report to a bug.

  Symptom:
  [ 8976.950635] audit: type=1400 audit(1491310016.224:48): apparmor="DENIED" 
operation="setrlimit" profile="/usr/sbin/libvirtd" pid=10034 comm="libvirtd" 
rlimit=memlock value=1610612736

  But none of the profiles has any rlimit statement in it:
  $ grep -Hirn limit /etc/apparmor*
  /etc/apparmor.d/sbin.dhclient:58:  # such, if the dhclient3 daemon is 
subverted, this effectively limits it to
  /etc/apparmor.d/abstractions/ubuntu-helpers:16:# Limitations:
  /etc/apparmor.d/abstractions/ubuntu-helpers:64:  # in limited libraries so 
glibc's secure execution should be enough to not
  /etc/apparmor.d/cache/.features:13:rlimit {mask {cpu fsize data stack core 
rss nproc nofile memlock as locks sigpending msgqueue nice rtprio rttime

  
  The profile contains a child profile which makes reading the dumps a bit 
painful, but I'll attach them anyway for you to take a look.
  To "recreate" if needed check out bug 1678322 - TL;DR hot-add some VFs via 
libvirt.

[Touch-packages] [Bug 1732032] Re: ip maddr show and ip maddr show dev enP20p96s0 show different data

Bug description:
  [Impact]
  When a nic has a long enough name such that there is no space between the 
name and the ":" in /proc/net/igmp, ip maddr show dev  will miss the IPV4 
addresses which is otherwise shown with "ip maddr show".

  This is inconsistent behavior and can break scripts and tests, as
  shown in this bug's original description.

  Three patches from upstream were taken to fix this bug, and they were used 
individually instead of being merged into one single patch so it's easier to 
track and recognize authorship:
  
https://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git/commit/?id=530903dd9003492edb0714e937ad4a5d1219e376
  
https://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git/commit/?id=b48a1161f5f9b6a0cda399a224bbbf72eba4a5c6
  
https://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git/commit/?id=21503ed2af233ffe795926f6641ac84ec1b15bf9

  [Test Case]
  * deploy the ubuntu release under test. Please use bare metal or a VM instead 
of containers, because the ip tool parses a file in /proc. Make sure iproute2 
is installed:
  sudo apt install iproute2

  * Run these commands to setup a dummy interface with a long name and
  an IPv4 address. Please change the address if it conflicts with a real
  network you might have available on that machine:

  sudo ip link add dummylongnic0 type dummy
  sudo ip addr add 192.168.199.10/24 dev dummylongnic0
  sudo ip link set dev dummylongnic0 up

  * Compare the output of these two commands with regards to the dummylongnic0 
interface:
  sudo ip maddr show
  sudo ip maddr show dev dummylongnic0

  * With the buggy iproute2 package installed, the more specific output "ip 
maddr show dev dummylongnic0" should lack the "inet 224.0.0.1" line:
  ip maddr show dev dummylongnic0
  2:dummylongnic0
link  33:33:00:00:00:01
link  01:00:5e:00:00:01
inet6 ff02::1
inet6 ff01::1

  
  Whereas the less specific command, which lists all interfaces, will have it 
listed for dummylongnic0:
  2:dummylongnic0
link  33:33:00:00:00:01
link  01:00:5e:00:00:01
inet  224.0.0.1
inet6 ff02::1
inet6 ff01::1

  
  * With the fixed iproute2 package, all dummylongnic0 addresses will be 
present in both outputs.

  
  [Regression Potential]
  In the end, the ip tool is parsing a text file produced by the kernel. As 
most parsing done in C, it's pretty low level and sensitive to changes in the 
file it's reading.

  [Other Info]
  I suggest to conduct the tests in VMs instead of containers (LXD) because the 
ip maddr command parses /proc/net/igmp, which is produced by the kernel. If you 
use a container, then it's the host's kernel that will be providing that file 
and it might not be the same as with the native kernel of that particular 
ubuntu release.

  --- Original description ---
  Attn. Canonical:  Please make sure that the existing iproute2 package gets 
updated with the two referenced patches as the missing information is impacting 
our standard test suites.

  Thanks.

Bug description:
  Calculate the checksum of data that is 16 byte aligned and a multiple
  of  16 bytes.

  The first step is to reduce it to 1024 bits. We do this in 8 parallel
   chunks in order to mask the latency of the vpmsum instructions. If we
   have more than 32 kB of data to checksum we repeat this step multiple
   times, passing in the previous 1024 bits.

   The next step is to reduce the 1024 bits to 64 bits. This step adds
   32 bits of 0s to the end - this matches what a CRC does. We just
   calculate constants that land the data in this 32 bits.

   We then use fixed point Barrett reduction to compute a mod n over GF(2)
   for n = CRC using POWER8 instructions. We use x = 32.

Bug description:
  [Impact]

  The aureport command, part of the audit userspace utilities,
  incorrectly reports the user id of successful logins. "-1" is printed
  instead of the expected user id.

  [Test Case]

  As root, run `login`. Proceed as follows:

  1. Login with a blank username and any password
  2. Login with an invalid username and any password
  3. Login with a valid username and an invalid password
  4. Login with a valid username and a valid password
  5. Exit from the login shell
  6. Run `aureport -l` and examine the last for login records

  An unpatched aureport will print the following:

  
  # date time auid host term exe success event
  
  ...
  2. 10/17/2017 23:45:32 UNKNOWN ? /dev/pts/8 /bin/login no 97
  3. 10/17/2017 23:45:39 UNKNOWN ? /dev/pts/8 /bin/login no 99
  4. 10/17/2017 23:45:45 tyhicks ? /dev/pts/8 /bin/login no 101
  5. 10/17/2017 23:45:49 -1 ? /dev/pts/8 /bin/login yes 107

  A patch aureport will print the correct output:

  Login Report
  
  # date time auid host term exe success event
  
  ...
  2. 10/17/2017 23:52:44 UNKNOWN ? /dev/pts/8 /bin/login no 165
  3. 10/17/2017 23:52:52 UNKNOWN ? /dev/pts/8 /bin/login no 167
  4. 10/17/2017 23:52:58 tyhicks ? /dev/pts/8 /bin/login no 169
  5. 10/17/2017 23:53:02 1000 ? /dev/pts/8 /bin/login yes 175

  Note the "1000" in the auid column on the #5 row. It should *not* be
  "-1".

  [Regression Potential]

  The regression potential is limited due to the change only affecting a
  single line of code, the fix comes from upstream, and that the
  aureport utility is not critical.

  [Original Report]

  == Comment: #0 - Miao Tao Feng  - 2016-11-23 02:46:25 ==
  When we develop new testcase for audit, we found that command "aureport -l" 
print out wrong auid "-1"  on ubuntu16.04  and it should be 1000 according to 
the audit.log.

  The following are details:

  root@roselp2:~# aureport -l

  Login Report
  
  # date time auid host term exe success event
  
  1. 11/23/2016 02:20:12 -1 10.33.24.118 /dev/pts/0 /usr/sbin/sshd yes 18

  The auid "-1" on the above line should be "1000? according to the
  audit.log.

   I have seen these messages logged more often when we do any hotplug

  Ok. .this is the continuation of LTC #144627 / Launchpad #1682774.

  As suggested in that bug, we did change udev script to create
  temporary file under /run and that patch is available in ubuntu 17.10.

  Looks like this is udev script issue. If I modify systemd-udevd like
  below it works fine.

  I've limited udev knowledge. I don't know if you have any other better
  solution to this issue.

  [Impact]
  When a nic has a long enough name such that there is no space between the 
name and the ":" in /proc/net/igmp, ip maddr show dev  will miss the IPV4 
addresses which is otherwise shown with "ip maddr show".

  This is inconsistent behavior and can break scripts and tests, as
  shown in this bug's original description.

  Three patches from upstream were taken to fix this bug, and they were used 
individually instead of being merged into one single patch so it's easier to 
track and recognize authorship:
  
https://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git/commit/?id=530903dd9003492edb0714e937ad4a5d1219e376
  
https://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git/commit/?id=b48a1161f5f9b6a0cda399a224bbbf72eba4a5c6
  
https://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git/commit/?id=21503ed2af233ffe795926f6641ac84ec1b15bf9

  [Test Case]
  * deploy the ubuntu release under test. Please use bare metal or a VM instead 
of containers, because the ip tool parses a file in /proc. Make sure iproute2 
is installed:
  sudo apt install iproute2

  * Run these commands to setup a dummy interface with a long name and
  an IPv4 address. Please change the address if it conflicts with a real
  network you might have available on that machine:

  sudo ip link add dummylongnic0 type dummy
  sudo ip addr add 192.168.199.10/24 dev dummylongnic0
  sudo ip link set dev dummylongnic0 up

  * Compare the output of these two commands with regards to the dummylongnic0 
interface:
  sudo ip maddr show
  sudo ip maddr show dev dummylongnic0

  * With the buggy iproute2 package installed, the more specific output "ip 
maddr show dev dummylongnic0" should lack the "inet 224.0.0.1" line:
  ip maddr show dev dummylongnic0
  2:dummylongnic0
link  33:33:00:00:00:01
link  01:00:5e:00:00:01
inet6 ff02::1
inet6 ff01::1

  
  Whereas the less specific command, which lists all interfaces, will have it 
listed for dummylongnic0:
  2:dummylongnic0
link  33:33:00:00:00:01
link  01:00:5e:00:00:01
inet  224.0.0.1
inet6 ff02::1
inet6 ff01::1

  
  * With the fixed iproute2 package, all dummylongnic0 addresses will be 
present in both outputs.

  
  [Regression Potential]
  In the end, the ip tool is parsing a text file produced by the kernel. As 
most parsing done in C, it's pretty low level and sensitive to changes in the 
file it's reading.

  [Other Info]
  I suggest to conduct the tests in VMs instead of containers (LXD) because the 
ip maddr command parses /proc/net/igmp, which is produced by the kernel. If you 
use a container, then it's the host's kernel that will be providing that file 
and it might not be the same as with the native kernel of that particular 
ubuntu release.

  --- Original description ---
  Attn. Canonical:  Please make sure that the existing iproute2 package gets 
updated with the two referenced patches as the missing information is impacting 
our standard test suites.

  Thanks.

  I found upstream already had patches that fix this problem:

  1) https://www.spinics.net/lists/netdev/msg415009.html
  commit 530903dd9003492edb0714e937ad4a5d1219e376

  ip: fix igmp parsing when iface is long

  Entries with long vhost names in /proc/net/igmp have no whitespace
  between name and colon, so sscanf() adds it to vhost and
  'ip maddr show iface' doesn't include inet result.

  Signed-off-by: Petr Vorel 

  
  2) https://www.spinics.net/lists/netdev/msg461479.html
  commit 21503ed2af233ffe795926f6641ac84ec1b15bf9

  ip maddr: fix filtering by device

  Commit 530903dd9003 ("ip: fix igmp parsing when iface is long") uses
  variable len to keep trailing colon from interface name comparison.  This
  variable is local to loop body but we set it in one pass and use it in
  following one(s) so that we are actually using (pseudo)random length for
  comparison. This became apparent since commit b48a1161f5f9 ("ipmaddr: 
Avoid
  accessing uninitialized data") always initializes len to zero so that the
  name comparison is always true. As a result, "ip maddr show dev eth0" 
shows
  IPv4 multicast addresses for all interfaces.

  Instead of keeping the length, let's simply replace the trailing colon 
with
  a null byte. The bonus is that we get correct interface name in ma.name.

  Fixes: 530903dd9003 ("ip: fix igmp parsing when iface is long")
  Signed-off-by: Michal Kubecek 
  Acked-by: Phil Sutter 
  Acked-by: Petr Vorel 

  The fix is in the same place, but different way.
  This is the current implementation In ip/ipmaddr.c file:
  struct ma_info *ma;

  if (buf[0] != '\t') {
  size_t len;

  sscanf(buf, "%d%s", &m.index, m.name);
  len = strlen(m.name);
  if (m.name[len - 1] == ':')
  m.name[len - 1] = '\0';
  continue;
  }

  
  The existing "ip" command that shows the problem:
  [root@coral-sriov-host1 ip]# /usr/sbin/ip maddr show dev enP1p12s0f0   /* <-- 
We do NOT see the IPv4 maddr */
  2:  enP1p12s0f0
  link  01:00:5e:00:00:01
  inet6 ff02::1
  inet6 ff01::1

  I clone the latest "ip" utility from upstream to the same test box.
  [root@coral-sriov-host1 git_iproute2]# git clone 
https://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git

  I build the "ip" utility on same test box, which has the above 2

   I have seen these messages logged more often when we do any hotplug 
operations.. ex. cpu hotplug..

  Ok. .this is the continuation of LTC #144627 / Launchpad #1682774.

  As suggested in that bug, we did change udev script to create
  temporary file under /run and that patch is available in ubuntu 17.10.

  Looks like this is udev script issue. If I modify systemd-udevd like
  below it works fine.

  I've limited udev knowledge. I don't know if you have any other better
  solution to this issue.

  == Comment: #12 - David Z. Dai  - 2017-11-13 15:07:32 ==

  I found upstream already had patches that fix this problem:

  1) https://www.spinics.net/lists/netdev/msg415009.html
  commit 530903dd9003492edb0714e937ad4a5d1219e376
  Author: Petr Vorel 
  Date:   Tue Jan 17 00:25:50 2017 +0100

  ip: fix igmp parsing when iface is long

  Entries with long vhost names in /proc/net/igmp have no whitespace
  between name and colon, so sscanf() adds it to vhost and
  'ip maddr show iface' doesn't include inet result.

  Signed-off-by: Petr Vorel 

  
  2) https://www.spinics.net/lists/netdev/msg461479.html
  commit 21503ed2af233ffe795926f6641ac84ec1b15bf9
  Author: Michal Kubecek 
  Date:   Thu Oct 19 10:21:08 2017 +0200

  ip maddr: fix filtering by device

  Commit 530903dd9003 ("ip: fix igmp parsing when iface is long") uses
  variable len to keep trailing colon from interface name comparison.  This
  variable is local to loop body but we set it in one pass and use it in
  following one(s) so that we are actually using (pseudo)random length for
  comparison. This became apparent since commit b48a1161f5f9 ("ipmaddr: 
Avoid
  accessing uninitialized data") always initializes len to zero so that the
  name comparison is always true. As a result, "ip maddr show dev eth0" 
shows
  IPv4 multicast addresses for all interfaces.

  Instead of keeping the length, let's simply replace the trailing colon 
with
  a null byte. The bonus is that we get correct interface name in ma.name.

  Fixes: 530903dd9003 ("ip: fix igmp parsing when iface is long")
  Signed-off-by: Michal Kubecek 
  Acked-by: Phil Sutter 
  Acked-by: Petr Vorel 

  The fix is in the same place, but different way.
  This is the current implementation In ip/ipmaddr.c file:
  struct ma_info *ma;

  if (buf[0] != '\t') {
  size_t len;

  sscanf(buf, "%d%s", &m.index, m.name);
  len = strlen(m.name);
  if (m.name[len - 1] == ':')
  m.name[len - 1] = '\0';
  continue;
  }

  
  The existing "ip" command that shows the problem:
  [root@coral-sriov-host1 ip]# /usr/sbin/ip maddr show dev enP1p12s0f0   /* <-- 
We do NOT see the IPv4 maddr */
  2:  enP1p12s0f0
  link  01:00:5e:00:00:01
  inet6 ff02::1
  inet6 ff01::1

  I clone the latest "ip" utility from upstream to the same test box.
  [root@coral-sriov-host1 git_iproute2]# git clone 
https://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git

  I build the "ip" utility on same test box, which has the above 2
  patches included.

  [root@coral-sriov-host1 ip]# /root/git_iproute2/iproute2/ip/ip maddr show dev 
enP1p12s0f0  /* <--- shows correct IPv4 maddr */
  2:  enP1p12s0f0

Title:
  ISST-LTE: pVM: aureport couldn't get the right auid from the audit log
  on ubuntu16.04

Status in The Ubuntu-power-systems project:
  In Progress
Status in audit package in Ubuntu:
  Invalid
Status in audit source package in Xenial:
  In Progress
Status in audit source package in Zesty:
  In Progress

Bug description:
  [Impact]

  The aureport command, part of the audit userspace utilities,
  incorrectly reports the user id of successful logins. "-1" is printed
  instead of the expected user id.

  [Test Case]

  As root, run `login`. Proceed as follows:

  1. Login with a blank username and any password
  2. Login with an invalid username and any password
  3. Login with a valid username and an invalid password
  4. Login with a valid username and a valid password
  5. Exit from the login shell
  6. Run `aureport -l` and examine the last for login records

  An unpatched aureport will print the following:

  
  # date time auid host term exe success event
  
  ...
  2. 10/17/2017 23:45:32 UNKNOWN ? /dev/pts/8 /bin/login no 97
  3. 10/17/2017 23:45:39 UNKNOWN ? /dev/pts/8 /bin/login no 99
  4. 10/17/2017 23:45:45 tyhicks ? /dev/pts/8 /bin/login no 101
  5. 10/17/2017 23:45:49 -1 ? /dev/pts/8 /bin/login yes 107

  A patch aureport will print the correct output:

  Login Report
  
  # date time auid host term exe success event
  
  ...
  2. 10/17/2017 23:52:44 UNKNOWN ? /dev/pts/8 /bin/login no 165
  3. 10/17/2017 23:52:52 UNKNOWN ? /dev/pts/8 /bin/login no 167
  4. 10/17/2017 23:52:58 tyhicks ? /dev/pts/8 /bin/login no 169
  5. 10/17/2017 23:53:02 1000 ? /dev/pts/8 /bin/login yes 175

  Note the "1000" in the auid column on the #5 row. It should *not* be
  "-1".

  [Regression Potential]

  The regression potential is limited due to the change only affecting a
  single line of code, the fix comes from upstream, and that the
  aureport utility is not critical.

  [Original Report]

  == Comment: #0 - Miao Tao Feng  - 2016-11-23 02:46:25 ==
  When we develop new testcase for audit, we found that command "aureport -l" 
print out wrong auid "-1"  on ubuntu16.04  and it should be 1000 according to 
the audit.log.

  The following are details:

  root@roselp2:~# aureport -l

  Login Report
  
  # date time auid host term exe success event
  
  1. 11/23/2016 02:20:12 -1 10.33.24.118 /dev/pts/0 /usr/sbin/sshd yes 18

  The auid "-1" on the above line should be "1000? according to the
  audit.log.

   I have seen these messages logged more often when we do any hotplug

  Ok. .this is the continuation of LTC #144627 / Launchpad #1682774.

  As suggested in that bug, we did change udev script to create
  temporary file under /run and that patch is available in ubuntu 17.10.

  Looks like this is udev script issue. If I modify systemd-udevd like
  below it works fine.

  I've limited udev knowledge. I don't know if you have any other better
  solution to this issue.

  [Ubuntu 1710] [Feature] Inconsistent report of pm CanSuspend state by
  systemd and pm-utils

Status in The Ubuntu-power-systems project:

Bug description:
  == Comment: #0 - Balamuruhan S <> - 2017-06-28 03:39:15 ==
  systemd and pm-utils interprets CanSuspend states differently and reports it 
as supported or not in a conflicting way.

  # gdbus call --system --dest org.freedesktop.login1 --object-path 
/org/freedesktop/login1 --method org.freedesktop.login1.Manager.CanSuspend
  ('yes',)

  # pm-is-supported --suspend
  # echo $?
  1

  Both systemd and pm-is-supported looks into /sys/power/state file to
  check if suspend is supported.

  pm-is-supported --suspend returns true if either "standby" or "mem" is 
present in the file.
  ( /usr/lib/pm-utils/pm-functions )

  systemd(Manager.CanSuspend) returns true if "standby", "freeze" or "mem" is 
present in the file.
  ( 
https://github.com/systemd/systemd/blob/dd8352659c9428b196706d04399eec106a8917ed/src/shared/sleep-config.c
 )

  # cat /sys/power/state
  freeze

  So here, pm-is-supported --suspend returns false and gdbus returns
  true.

  Both these utilities interpret /sys/power/state differently.

  Secondly, systemd should split CanSuspend to Cansuspend+CanFreeze Or
  don't report freeze as CanSuspend.

  Impact of this inconsistency can be felt from Libvirt supported pm
  states:

  To reduce ABI dependency, libvirt queries the available states via
  dbus, if not falls to pm-utils. Libvirt won't check for strings in
  sys/power/state and interpret directly.

  so due to this, libvirt will list that suspend_to_mem is supported
  from virsh capabilities but ideally it might not.

  [SRU justification]
  Before systemd 232, UserTasksMax=infinity is not respected in logind.conf, 
despite the documentation referring to systemd.resource-control(5) for the 
definition of this field. This limits the use of Ubuntu 16.04 and later in 
contexts where a user session should be permitted to allocate large numbers of 
processes.

  [Test case]
  1. Set UserTasksMax=infinity in /etc/systemd/logind.conf.
  2. Create a new login session.
  3. Check the ulimit for user processes with 'ulimit -u'.
  4. Verify that the limit has a numeric value.
  5. Upgrade to systemd from -proposed.
  6. Create a new login session.
  7. Check the ulimit for user processes with 'ulimit -u'.
  8. Verify that the limit is now set to 'unlimited'.

  [Regression potential]
  This is an upstream patch which is part of 232 and later without issues and 
clearly addresses the bug in question.  While the upstream commit includes code 
changes that are not strictly required in order to fix this bug, these are 
mostly cosmetic and should not carry significant additional risk.

  udev: boot script does not trigger subsystem coldplug

Status in The Ubuntu-power-systems project:
  New
Status in systemd package in Ubuntu:
  New

Bug description:
  The udev initramfs-tools boot script does not trigger subsystem "add"
  uevents. As a result, udev rules that listen to subsystem "add" events
  are never activated. This problem exists on at least Ubuntu 16.04 and
  17.10.

  On s390, this results in a boot failure if the kernel is configured to
  start with an active device black list (kernel parameter
  cio_ignore=all,!condev). An example for an affected udev rule looks
  like this:

  ACTION=="add", SUBSYSTEM=="subsystem", KERNEL=="ccw",
  RUN{program}+="/bin/sh -c 'echo free 0009,ec30,ec32,f5f0-f5f2 >
  /proc/cio_ignore'"

  A proposed fix would be:

  Modify /usr/share/initramfs-tools/scripts/init-top/udev:

  Replace line
  udevadm trigger --action=add
  with
  udevadm trigger --type=subsystems --action=add
  udevadm trigger --type=devices --action=add

  This would also be consistent with the steps that the systemd udev
  coldplug unit file performs (see /lib/systemd/system/systemd-udev-
  trigger.service).

[Touch-packages] [Bug 1623383] Re: Some restarts fail due to missing base devices

[Andrew Cloke]

Hi, we’re trying to explore different approaches to investigate, resolve
and/or work around this issue, but regrettably there do not appear to be
any simple solutions.

Would it be possible to record the failure rate during the testing for
the next SRU cycle? Perhaps something simple like “5 failures in 50
redeployments over a 2 week period”?

Many thanks.

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  Arch: s390x
  Release: Yakkety / 16.10

  This happens on some (but not all) system starts with Yakkety. In
  Xenial (which is using the same 4.4 kernel version the Yakkety systems
  were using when the problem was first observed) this did not happen.
  The system (LPAR) this was seen first was an upgrade from Xenial but
  since then has been freshly installed with Yakkety. The same behaviour
  is seen on a zVM guest running Yakkety.

  The attached syslog shows a failed boot, followed by one that did work. Note 
the "Found device .*(sclp|encc00).*" messages in the good boot. Those are 
missing in the bad attempt and as a result networking and console fail to be 
usable. Also note, those boots were 4.8 kernels but we saw this with 4.4 
kernels, too.
  This might be a systemd problem / race, I just filed it into udev for now as 
that better matches the not finding basic devices symptom.

[Touch-packages] [Bug 1464442] Re: installing or upgrading libc6 in Trusty removes all content from /tmp directory

[Andrew Cloke]

This bug is also effecting the MAAS 1.7.1 deployment of Ubuntu 14.04
onto a diskless server with access to iSCSI LUN, as described in
https://bugs.launchpad.net/curtin/+bug/1425264/.

I've marked LP#1425264 as a dup of this bug.

Title:
  installing or upgrading libc6 in Trusty removes all content from /tmp
  directory

Status in eglibc package in Ubuntu:
  Confirmed

Bug description:
  We are seeing an issue with installation of dkms package during a
  curtin installation which ends up with /tmp directory being wiped
  clean. This is very bad for curtin as it saves critical installation
  files in /tmp.

  It turns out that it's the of upgrading libc6, which is triggered as a
  result of installing dependencies, that removes content of /tmp. For
  example, installation of gcc results in the same result since it ends
  up with libc6 being upgraded. The only way that this won't be
  recreated is if the latest libc6 is already installed.

  This problem does not exist in precise. It can also be recreated by
  installing the .deb file for any version in trusty including 2.17.
