An overlayfs mount using an upper or lower directory from a

that if any lower or upper directory is nosuid at mount time the

UBUNTU: SAUCE: overlayfs: Be more careful about copying up sxid files
When an overlayfs filesystem's lowerdir is on a nosuid filesystem
but the upperdir is not, it's possible to copy up an sxid file or
stick directory into upperdir without changing the mode by
opening the file rw in the overlayfs mount without writing to it.
This makes it possible to bypass the nosuid restriction on the
lowerdir mount.
It's a bad idea in general to let the mounter copy up a sxid file
if the mounter wouldn't have had permission to create the sxid
file in the first place. Therefore change ovl_set_xattr to
exclude these bits when initially setting the mode, then set the
full mode after setting the user for the inode. This allows copy
up for non-sxid files to work as before but causes copy up to
fail for the cases where the user could not have created the sxid
inode in upperdir.
In the mark_source_chains function (net/ipv4/netfilter/ip_tables.c) it
is possible for a user-supplied ipt_entry structure to have a large
next_offset field. This field is not bounds checked prior to writing a
counter value at the supplied offset.
Problem is that xt_entry_foreach() macro stops iterating once e->next_offset
is out of bounds, assuming this is the last entry.
With malformed data thats not necessarily the case so we can
write outside of allocated area later as we might not have walked the
entire blob.
Fix this by simplifying mark_source_chains -- it already has to check
if nextoff is in range to catch invalid jumps, so just do the check
when we move to a next entry as well.
Also, check that the offset meets the xtables_entry alignment.

Linux kernel people think that the systemd's hardcoded timeout is a

Although Linux kernel people are expecting fusion driver module not

Therefore, this patch changes kthread_create() to wait for up to 10
seconds after receiving SIGKILL, unless chosen by the OOM killer,
in order to give the kthreadd a chance to complete the request.
The side effect of this patch is that current thread's response to

10 seconds).

So, according to the upstream discussion David Zeuthen recommended
to just not lock CD-ROM trays by default. Kernel/userspace already
handles prematurely removed USB storage devices reasonably, and with
read-only devices like CD-ROMs it is even less of an issue. So we
should just set /proc/sys/dev/cdrom/lock to 0 by default.
Note that we still will have the drive mounted after the eject. There is a
media change uevent generated and this will be used to trigger the unmount
of the drive in udisks. The burner software will also have to be looked
at to ensure they are explicitly locking the drive closed during the burn.

Pull RISC-V fix from Palmer Dabbelt:
