This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to '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 be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Bug 1919847] Re: rshim logging buffer could overflow and get lost
** Description changed: On Bluefield platforms, the 'bfrshlog' script can be used to write a string into the internal rshim logging buffer which has size 1KB. When the buffer is full, the intention is to drop the new data. However, due to a bug, the buffer could be overwritten and wrap-around when full. SRU Justification: [Impact] - * When 'cat /dev/rshim/misc' with DISPLAY_LEVEL set to 2, the logging buffer could be potentially displayed as empty when it's full. + * When 'cat /dev/rshim0/misc' with DISPLAY_LEVEL set to 2, the logging buffer could be potentially displayed as empty when it's full. [Fix] * Add the check properly to make sure the buffer won't wrap-around. [Test Case] - * Run "bfrshlog " repeatedly and check the /dev/rshim/misc with DISPLAY_LEVEL set to 2 in this file. The buffer shouldn't be overwritten or wrap-around. - + * Run "bfrshlog " repeatedly and check the /dev/rshim0/misc with DISPLAY_LEVEL set to 2 in this file. The buffer shouldn't be overwritten or wrap-around. [Regression Potential] - * Yes, it should be easy to add regression. + * The rshim log can be displayed by setting "DISPLAY_LEVEL 2" in /dev/rshim0/misc, then "cat /dev/rshim0/misc" to see the log messages. The log should contains ATF/UEFI booting progress and user logs from Linux applications by using the bfrshlog script. In any case, the log should always start from ATF logging, not overwritten or wrap-around. When the buffer is full, new data will be dropped.
