[sle-beta] kernel-default-4.4.131-94.29-1

[Waite, Dick (External)]

Grand Morning,

My input was from the "Linux on 390 Port". My day job is mostly on s390x and I was thinking on updating some machine on Saturday but they do mostly use XFS as do many of my x86_64 virtual machines running on VMware.. Their ticket number is an IBM one.

=========================  ==============================================
Suse just released a new kernel-default-4.4.131-94.29-1 package for SLES 12SP3 with some kernel security fixes.  If you use XFS, don't install it!
I installed it and the system wouldn't mount an existing XFS filesystem.  Our friendly Suse engineer (thanks, Roberto!) told me that it's a regression in the kernel.  A *NEW* XFS filesystem created under this kernel mounted under both 4.4.131 and the older 4.4.126.
The biggest fix with this kernel is that now we have a file for speculative store bypass.  If you cat it (/sys/devices/system/cpu/vulnerabilities/spec_store_bypass) you get "Not Affected".  So I don't think waiting for the fix will significantly harm anyone's system security...
If anyone cares, our ticket is SR101165092091

Another post from there ....

There has been an (at least) four way finger pointing contest
raging for the last couple of months (on the Fedoraproject
front) between:
        - xfs developers
        - systemd developers
        - dracut developers
        - innocent victims of XFS

Here is a trailhead to read back and forth from:
