Now that the previous patch gave objtool the ability to read retpoline
alternatives, it shows a new warning:
arch/x86/entry/entry_64.o: warning: objtool: .entry_trampoline: don't know how to handle alternatives at end of section
This is due to the JMP_NOSPEC in entry_SYSCALL_64_trampoline().
Previously, objtool ignored this situation because it wasn't needed, and
it would have required a bit of extra code. Now that this case exists,
add proper support for it.

Currently objtool requires all retpolines to be:
a) patched in with alternatives; and
b) annotated with ANNOTATE_NOSPEC_ALTERNATIVE.
If you forget to do both of the above, objtool segfaults trying to
dereference a NULL 'insn->call_dest' pointer.
Avoid that situation and print a more helpful error message:
quirks.o: warning: objtool: efi_delete_dummy_variable()+0x99: unsupported intra-function call
quirks.o: warning: objtool: If this is a retpoline, please patch it in with alternatives and annotate it with ANNOTATE_NOSPEC_ALTERNATIVE.
Future improvements can be made to make objtool smarter with respect to
retpolines, but this is a good incremental improvement for now.

The 32-bit compat v4l2 ioctl handling is implemented based on its 64-bit
equivalent. It converts 32-bit data structures into its 64-bit
equivalents and needs to provide the data to the 64-bit ioctl in user
space memory which is commonly allocated using
compat_alloc_user_space().
However, due to how that function is implemented, it can only be called
a single time for every syscall invocation.
Supposedly to avoid this limitation, the existing code uses a mix of
memory from the kernel stack and memory allocated through
compat_alloc_user_space().
Under normal circumstances, this would not work, because the 64-bit
ioctl expects all pointers to point to user space memory. As a
workaround, set_fs(KERNEL_DS) is called to temporarily disable this
extra safety check and allow kernel pointers. However, this might
introduce a security vulnerability: The result of the 32-bit to 64-bit
conversion is writeable by user space because the output buffer has been
allocated via compat_alloc_user_space(). A malicious user space process
could then manipulate pointers inside this output buffer, and due to the
previous set_fs(KERNEL_DS) call, functions like get_user() or put_user()
no longer prevent kernel memory access.
The new approach is to pre-calculate the total amount of user space
memory that is needed, allocate it using compat_alloc_user_space() and
then divide up the allocated memory to accommodate all data structures
that need to be converted.
An alternative approach would have been to retain the union type karg
that they allocated on the kernel stack in do_video_ioctl(), copy all
data from user space into karg and then back to user space. However, we
decided against this approach because it does not align with other
compat syscall implementations. Instead, we tried to replicate the
get_user/put_user pairs as found in other places in the kernel:
if (get_user(clipcount, &up->clipcount) ||
put_user(clipcount, &kp->clipcount)) return -EFAULT;
Notes from hans.verkuil@cisco.com:
This patch was taken from:
https://github.com/LineageOS/android_kernel_samsung_apq8084/commit/97b733953c06e4f0398ade18850f0817778255f7
Clearly nobody could be bothered to upstream this patch or at minimum
tell us :-( We only heard about this a week ago.
This patch was rebased and cleaned up. Compared to the original I
also swapped the order of the convert_in_user arguments so that they
matched copy_in_user. It was hard to review otherwise. I also replaced
the ALLOC_USER_SPACE/ALLOC_AND_GET by a normal function.

ctrl_is_pointer just hardcoded two known string controls, but that
caused problems when using e.g. custom controls that use a pointer
for the payload.
Reimplement this function: it now finds the v4l2_ctrl (if the driver
uses the control framework) or it calls vidioc_query_ext_ctrl (if the
driver implements that directly).
In both cases it can now check if the control is a pointer control
or not.

Don't duplicate the buffer type checks in enum/g/s/try_fmt.
The check_fmt function does that already.
It is hard to keep the checks in sync for all these functions and
in fact the check for VBI was wrong in the _fmt functions as it
allowed SDR types as well. This caused a v4l2-compliance failure
for /dev/swradio0 using vivid.
This simplifies the code and keeps the check in one place and
fixes the SDR/VBI bug.

If the framebuffer is enabled and error injection is disabled, then
creating the controls for the video output device would fail with an
error.
This is because the Clear Framebuffer control uses the 'vivid control
class' and that control class isn't added if error injection is disabled.
In addition, this control was added to e.g. vbi devices as well, which
makes no sense.
Move this control to its own control handler and handle it correctly.

The RDMA subsystem has very strict set of objects to work with, but it
completely lacks tracking facilities and has no visibility of resource
utilization.
The following patch adds such infrastructure to keep track of RDMA
resources to help with debugging of user space applications. The primary
user of this infrastructure is RDMA nldev netlink (following patches), to
be exposed to userspace via rdmatool, but it is not limited too that.
At this stage, the main three objects (PD, CQ and QP) are added, and more
will be added later.

7441b0627e22 ("s390/pci: PCI hotplug support via SCLP") added
s390_pci_hpc.c, which included this license information:
+MODULE_LICENSE("GPL");
Based on "git show 7441b0627e22:include/linux/module.h", that "GPL" string
means "GPL v2 or later":
* "GPL" [GNU Public License v2 or later]
0729dcf24832 ("s390: hotplug: make pci_hpc explicitly non-modular")
subsequently replaced the MODULE_LICENSE() with a "License: GPL" comment.
Add SPDX GPL-2.0+ and remove the "License: GPL" comment, relying on the
assertion in b24413180f56 ("License cleanup: add SPDX GPL-2.0 license
identifier to files with no license") that the SPDX identifier may be used
instead of the full boilerplate text.

Wait for a response from the VNIC server before exiting after setting
the MAC address. The resolves an issue with bonding a VNIC client in
ALB or TLB modes. The bonding driver was changing the MAC address more
rapidly than the device could respond, causing the following errors.
"bond0: the hw address of slave eth2 is in use by the bond;
couldn't find a slave with a free hw address to give it
(this should not have happened)"
If the function waits until the change is finalized, these errors are
avoided.

Pull btrfs updates from David Sterba:
"Features or user visible changes:
- fallocate: implement zero range mode
- avoid losing data raid profile when deleting a device
- tree item checker: more checks for directory items and xattrs
Notable fixes:
- raid56 recovery: don't use cached stripes, that could be
potentially changed and a later RMW or recovery would lead to
corruptions or failures
- let raid56 try harder to rebuild damaged data, reading from all
stripes if necessary
- fix scrub to repair raid56 in a similar way as in the case above
Other:
- cleanups: device freeing, removed some call indirections, redundant
bio_put/_get, unused parameters, refactorings and renames
- RCU list traversal fixups
- simplify mount callchain, remove recursing back when mounting a
subvolume
- plug for fsync, may improve bio merging on multiple devices
- compression heurisic: replace heap sort with radix sort, gains some
performance
- add extent map selftests, buffered write vs dio"

Pull inode->i_version rework from Jeff Layton:
"This pile of patches is a rework of the inode->i_version field. We
have traditionally incremented that field on every inode data or
metadata change. Typically this increment needs to be logged on disk
even when nothing else has changed, which is rather expensive.
It turns out though that none of the consumers of that field actually
require this behavior. The only real requirement for all of them is
that it be different iff the inode has changed since the last time the
field was checked.
Given that, we can optimize away most of the i_version increments and
avoid dirtying inode metadata when the only change is to the i_version
and no one is querying it. Queries of the i_version field are rather
rare, so we can help write performance under many common workloads.
This patch series converts existing accesses of the i_version field to
a new API, and then converts all of the in-kernel filesystems to use
it. The last patch in the series then converts the backend
implementation to a scheme that optimizes away a large portion of the
metadata updates when no one is looking at it.
In my own testing this series significantly helps performance with
small I/O sizes. I also got this email for Christmas this year from
the kernel test robot (a 244% r/w bandwidth improvement with XFS over
DAX, with 4k writes):

A few of the earlier patches in this pile are also flowing to you via
other trees (mm, integrity, and nfsd trees in particular)".
