Title:
multiple UBSAN warnings in Intel IPU6 camera driver at boot
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Jammy:
Fix Committed
Bug description:
[SRU Justfication]
[Impact]
Several UBSAN warnings captured on Intel IPU6 camera equipped platforms
running 5.15+ kernels.
[Fix]
Upstream fix commit 8dcb7d8df28f ("media: pci: intel: Avoid UBSAN
warnings of index bound and shift").
[Test Case]
Boot Intel IPU6 camera equipped platforms and check dmesg.
[Where problems could occur]
This patch turns a few return statements to error to stop further
processing that may fall in UBSAN warnings. No other side effect.
[Other Info]
While plan for -generic and oem-5.17 is still under discuss, only Jammy
is nominated for linux-oem-5.14/focal migration (to hwe-5.15).
This depends on the pull request titled "Support Intel IPU6 MIPI camera
on Alder Lake platforms" for bug 1955383 for Jammy.
== original bug report ==
UBSAN is turned on by default in Ubuntu 5.15 kernel. While Intel IPU6
driver is still suffering from bug 1958004, intel_iommu issue, so
these are found with intel_iommu=off.

Title:
multiple UBSAN warnings in Intel IPU6 camera driver at boot
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Jammy:
Fix Committed
Bug description:
[SRU Justfication]
[Impact]
Several UBSAN warnings captured on Intel IPU6 camera equipped platforms
running 5.15+ kernels.
[Fix]
Upstream fix commit 8dcb7d8df28f ("media: pci: intel: Avoid UBSAN
warnings of index bound and shift").
[Test Case]
Boot Intel IPU6 camera equipped platforms and check dmesg.
[Where problems could occur]
This patch turns a few return statements to error to stop further
processing that may fall in UBSAN warnings. No other side effect.
[Other Info]
While plan for -generic and oem-5.17 is still under discuss, only Jammy
is nominated for linux-oem-5.14/focal migration (to hwe-5.15).
This depends on the pull request titled "Support Intel IPU6 MIPI camera
on Alder Lake platforms" for bug 1955383 for Jammy.
== original bug report ==
UBSAN is turned on by default in Ubuntu 5.15 kernel. While Intel IPU6
driver is still suffering from bug 1958004, intel_iommu issue, so
these are found with intel_iommu=off.

'verification-done-focal'. If the problem still exists, change the tag
'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will

Title:
multiple UBSAN warnings in Intel IPU6 camera driver at boot
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Jammy:
Fix Committed
Bug description:
[SRU Justfication]
[Impact]
Several UBSAN warnings captured on Intel IPU6 camera equipped platforms
running 5.15+ kernels.
[Fix]
Upstream fix commit 8dcb7d8df28f ("media: pci: intel: Avoid UBSAN
warnings of index bound and shift").
[Test Case]
Boot Intel IPU6 camera equipped platforms and check dmesg.
[Where problems could occur]
This patch turns a few return statements to error to stop further
processing that may fall in UBSAN warnings. No other side effect.
[Other Info]
While plan for -generic and oem-5.17 is still under discuss, only Jammy
is nominated for linux-oem-5.14/focal migration (to hwe-5.15).
This depends on the pull request titled "Support Intel IPU6 MIPI camera
on Alder Lake platforms" for bug 1955383 for Jammy.
== original bug report ==
UBSAN is turned on by default in Ubuntu 5.15 kernel. While Intel IPU6
driver is still suffering from bug 1958004, intel_iommu issue, so
these are found with intel_iommu=off.
