[Bug 1799281] [NEW] [Bionic][Cosmic] ipmi: Fix timer race with module unload
Public bug reported:
[Impact]
If you attempt to remove and insert the ipmi_ssif module a number of times, it
would result in a kernel panic. This is due to mod_timer from arming a timer
that was already removed by del_timer during module unload.
[Fix]
In linux-next:

-- Test Case --
for i in {1..500}; do sudo modprobe -r ipmi_ssif; sleep 2s ; sudo modprobe

After the patch was applied, no kernel panics were obsereved. Tested on Cavium
ThunderX2.
[Regression Risk]
The patch was applied to bionic and tested tested on a Cavium ThunderX2 and no
regressions were found. Risk of regression none.

[Bug 1799276] [NEW] [Bionic] ipmi: Remove ACPI SPMI probing from the SSIF (I2C) driver
Public bug reported:
[Impact]
The IPMI spec states:
The purpose of the SPMI Table is to provide a mechanism that can be used
by the OSPM (an ACPI term for “OS Operating System-directed
configuration and Power Management” essentially meaning an ACPI-aware OS
or OS loader) very early in the boot process, e.g., before the ability
to execute ACPI control methods in the OS is available.
When we are probing IPMI in Linux, ACPI control methods are available,
so we shouldn't be probing using SPMI. It could cause some confusion
during the probing process.
[Fix]
Fixed upstream in 4.17:
commit 4866b1dce0389013a268f0ab63f7229b30c6e5fe

[Bug 1797202] Re: [Bionic] arm64: topology: Avoid checking numa mask for scheduler MC selection
** Description changed:
[Impact]
The numa mask subset check can often lead to system hang or crash during CPU
hotplug and system suspend operation if NUMA is disabled. This is mostly
observed on HMP systems where the CPU compute capacities are different and ends
up in different scheduler domains. Since cpumask_of_node is returned instead
core_sibling, the scheduler is confused with incorrect cpumasks(e.g. one CPU in
two different sched domains at the same time) on CPU hotplug.
[Fix]
The following patch fixes this issue:

[Bug 1797200] Re: [Bionic] ACPI / PPTT: use ACPI ID whenever ACPI_PPTT_ACPI_PROCESSOR_ID_VALID is set
** Description changed:
[Impact]
Currently, we use the ACPI processor ID only for the leaf/processor nodes as
the specification states it must match the value of the ACPI processor ID field
in the processor’s entry in the MADT.
- However, if a PPTT structure represents a processors group, it matches a
processor container UID in the namespace and the
ACPI_PPTT_ACPI_PROCESSOR_ID_VALID flag indicates whether the ACPI processor ID
is valid.
-
- Let's use UID whenever ACPI_PPTT_ACPI_PROCESSOR_ID_VALID is set to be
consistent instead of using table offset as it's currently done for non-leaf
nodes.
-
- Fixes: 2bd00bcd73e5 (ACPI/PPTT: Add Processor Properties Topology Table
parsing)

[Bug 1765653] Re: directory-concurrent.sh.ext4 in ubuntu_ecryptfs failed on Atrful and Bionic ThunderX ARM64
This is a test case issue, and the failure is a false positive. ecryptfs/tests/kernel/directory-concurrent/test.c hang_check() the parent uses select() to check to see if the child process has completed. The child process lets the parent know that its done by writing "EXIT" to a pipe. select() is non blocking while read() is blocking, so the select() would timeout after 30s if nothing was read from the pipe, this timeout state is used to detect a hang in rmdir/mkdir. But the test does not take into account of the fact that there is no guarantee that the the order of execution after a fork() will be child first and then parent. If the parent executes before the child, we hit these false positives. The sync between parent and child can be achieved by calling wait(NULL) before select(), ie let the parent wait for the child state to change, but if there really is a hang in rmdir/mkdir the parent would hang indefinitely, and that would defeat the tests purpose of detecting hangs. I found that as a workaround, adding a sleep(1) after write() in the child helps with resolving this issue. I tested this multiple times successfully. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1765653 Title: directory-concurrent.sh.ext4 in ubuntu_ecryptfs failed on Atrful and Bionic ThunderX ARM64 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1765653/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1787240] [NEW] [Bionic] i2c: xlp9xx: Fix case where SSIF read transaction completes early
Public bug reported:
[Impact]
i2c: xlp9xx: Fix case where SSIF read transaction completes early
During ipmi stress tests we see occasional failure of transactions
at the boot time. This happens in the case of a I2C_M_RECV_LEN
transactions, when the read transfer completes (with the initial
read length of 34) before the driver gets a chance to handle interrupts.
[Test]
Use ipmitool to generate a lot of data read, run multiple instances of the
following test:
for i in {1..200}; do sudo ipmitool sel list ; sudo ipmitool sensor list ;
sudo ipmitool sdr list ; sudo ipmitool sel list ; done
[Fix]
Following upstream patch fixes this issue:
commit 5eb173f5c8f3a3cdc47b3952c368f10a28c81ab8
Author: George Cherian
Date: Wed Aug 8 23:36:48 2018 -0700
i2c: xlp9xx: Fix case where SSIF read transaction completes early
[Regression Risk]
The fix is to the i2c-xlp9xx driver, and does not impact any platform code.
Risk of regression is low.
