applied on top, but *excluding* the "af_unix: fix use-after-free in
unix_stream_read_actor()" patch, and my VM boots cleanly, without any
crashes.
When I try to boot a build of the exact same kernel, but *including*
the "af_unix: fix use-after-free in unix_stream_read_actor()" patch,
the VM crashes during boot (as stated in my previous email), so I'm
now 100% certain that this patch is causing the crashes.
Can you try booting the latest 6.7-rc and see what happens? That might give
us a further clue. I'm running 6.6.3-rc with this patch, various apps use
Unix sockets and there is not problem so far.
I can try 6.7-rc, but compiling will take a while.
At least with 6.6.3-rc, The crashes seem occur only with the specific
config that I had attached to my first email. I had originally tried
with a localmodconfig to speed up compiling when tracking down the
crashes, but I couldn't reproduce the crashes with the localmodconfig
kernel.
