Subject: linux-image-6.1.0-11-amd64: kernel disk device cache coherency issue: stale reads on /dev/sda1
Date: Sat, 26 Aug 2023 07:38:04 -0700
Package: src:linux
Version: 6.1.38-4
Severity: important

Dear Maintainer,

   * What led up to the situation?

Upgrade to bookworm fragmented the EFI paritition (due to changing boot logo) and defrag was in order. As this BIOS
currently has broken legacy boot, I used dosbox-x to defrag the EFI partition rather than boot the FreeDOS CD-ROM.
Thus this uncovered the bug. On minimizing the bug, it got very simple. I can reliably reproduce as follows:

# hexedit /dev/sda
G 100000  (your value may vary)
PgDn
PgDn
^C
# hexedit /dev/sda1
PgDn
write a marker to the padding between the BPB and the first FAT sector.
(If your system doesn't have one, edit an error message in the boot sector)
# hexedit /dev/sda1
G 100000
PgDn
PgDn
Look for marker written above, find it's not there !!!
^C

For demonstration of the fact the cache is wrong but the data is sved, you can do the following:

# reboot
# hexedit /dev/sda
G 10000
PgDn
PgDn
Look for marker written above, find it's there !!!

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Only effective workaround I could find was reboot at certain locations.

   * What outcome did you expect instead?

I seriously expect no possability of block level cache incoherency between
different partition devices on the same block device.
Quite frankly, I am amazed this doesn't cause tons and tons of issues.

Thanks for reporting back. In this case can you please report it to

I'm reopening the bug.

Thanks already!

Hi Joshua,

Went trough the upstream posting at
https://lore.kernel.org/lkml/CA+jjjYTk=5wn2o46uNB+bJYX8xLgMP==dsJuvC94DvtN2f_6Yw@mail.gmail.com/
.

So as long there is nothing ongoing upstream related to it, we can
neither do something downstream.

Regards,
Salvatore

As this usage of block devices is not supported by upstream and that
isn't likely to change, I'm marking this wontfix and reducing severity.
