TTY/Serial patches for 4.20-rc1
Here is the big tty and serial pull request for 4.20-rc1 Lots of little things here, including a merge from the SPI tree in order to keep things simpler for everyone to sync around for one platform. Major stuff is: - tty buffer clearing after use - atmel_serial fixes and additions - xilinx uart driver updates and of course, lots of tiny fixes and additions to individual serial drivers. All of these have been in linux-next with no reported issues for a while.

Staging/IIO patches for 4.20-rc1
Here is the big staging and IIO driver pull request for 4.20-rc1.
There are lots of things here, we ended up adding more lines than
removing, thanks to a large influx of Comedi National Instrument device
support. Someday soon we need to get comedi out of staging...
Other than the comedi drivers, the "big" things here are:
- new iio drivers
- delete dgnc driver (no one used it and no one had the hardware
anymore)
- vbox driver updates and fixes
- erofs fixes
- tons and tons of tiny checkpatch fixes for almost all staging
drivers
All of these have been in linux-next, with the last few happening a bit
"late" due to them getting stuck on my laptop during travel to the
Mantainers summit.
When merging with your tree, there will be 2 merge conflicts, both files
will be simple to resolve, just delete them :)

Merge tag '9p-for-4.20' of git://github.com/martinetd/linux
Pull 9p updates from Dominique Martinet:
"Highlights this time around are the end of Matthew's work to remove
the custom 9p request cache and use a slab directly for requests, with
some extra patches on my end to not degrade performance, but it's a
very good cleanup.
Tomas and I fixed a few more syzkaller bugs (refcount is the big one),
and I had a go at the coverity bugs and at some of the bugzilla
reports we had open for a while.
I'm a bit disappointed that I couldn't get much reviews for a few of
my own patches, but the big ones got some and it's all been soaking in
linux-next for quite a while so I think it should be OK.
Summary:

- Embed part of the fcall in the request to have better slab

net: diag: document swapped src/dst in udp_dump_one.
Since its inception, udp_dump_one has had a bug where userspace
needs to swap src and dst addresses and ports in order to find
the socket it wants. This is because it passes the socket source
address to __udp[46]_lib_lookup's saddr argument, but those
functions are intended to find local sockets matching received
packets, so saddr is the remote address, not the local address.
This can no longer be fixed for backwards compatibility reasons,
so add a brief comment explaining that this is the case. This
will avoid confusion and help ensure SOCK_DIAG implementations
of new protocols don't have the same problem.

Merge branch 'macsec-fixes'
Sabrina Dubroca says: ==================== macsec: linkstate fixes This series fixes issues with handling administrative and operstate of macsec devices. Radu Rendec proposed another version of the first patch [0] but I'd rather not follow the behavior of vlan devices, going with macvlan does instead. Patrick Talbert also reported the same issue to me. The second patch is a follow-up. The restriction on setting the device up is a bit unreasonable, and operstate provides the information we need in this case.

macsec: let the administrator set UP state even if lowerdev is down
Currently, the kernel doesn't let the administrator set a macsec device
up unless its lower device is currently up. This is inconsistent, as a
macsec device that is up won't automatically go down when its lower
device goes down.
Now that linkstate propagation works, there's really no reason for this
limitation, so let's remove it.

macsec: update operstate when lower device changes
Like all other virtual devices (macvlan, vlan), the operstate of a
macsec device should match the state of its lower device. This is done
by calling netif_stacked_transfer_operstate from its netdevice notifier.
We also need to call netif_stacked_transfer_operstate when a new macsec
device is created, so that its operstate is set properly. This is only
relevant when we try to bring the device up directly when we create it.
Radu Rendec proposed a similar patch, inspired from the 802.1q driver,
that included changing the administrative state of the macsec device,
instead of just the operstate. This version is similar to what the
macvlan driver does, and updates only the operstate.

net: sched: gred: pass the right attribute to gred_change_table_def()
gred_change_table_def() takes a pointer to TCA_GRED_DPS attribute,
and expects it will be able to interpret its contents as
struct tc_gred_sopt. Pass the correct gred attribute, instead of
TCA_OPTIONS.
This bug meant the table definition could never be changed after
Qdisc was initialized (unless whatever TCA_OPTIONS contained both
passed netlink validation and was a valid struct tc_gred_sopt...).
Old behaviour:
$ ip link add type dummy
$ tc qdisc replace dev dummy0 parent root handle 7: \
gred setup vqs 4 default 0
$ tc qdisc replace dev dummy0 parent root handle 7: \
gred setup vqs 4 default 0
RTNETLINK answers: Invalid argument
Now:
$ ip link add type dummy
$ tc qdisc replace dev dummy0 parent root handle 7: \
gred setup vqs 4 default 0
$ tc qdisc replace dev dummy0 parent root handle 7: \
gred setup vqs 4 default 0
$ tc qdisc replace dev dummy0 parent root handle 7: \

ptp: drop redundant kasprintf() to create worker name
Building with -Wformat-nonliteral, gcc complains
drivers/ptp/ptp_clock.c: In function ‘ptp_clock_register’:
drivers/ptp/ptp_clock.c:239:26: warning: format not a string literal and no format arguments [-Wformat-nonliteral]
worker_name : info->name);
kthread_create_worker takes fmt+varargs to set the name of the
worker, and that happens with a vsnprintf() to a stack buffer (that is
then copied into task_comm). So there's no reason not to just pass
"ptp%d", ptp->index to kthread_create_worker() and avoid the
intermediate worker_name variable.

net: bridge: remove ipv6 zero address check in mcast queries
Recently a check was added which prevents marking of routers with zero
source address, but for IPv6 that cannot happen as the relevant RFCs
actually forbid such packets:
RFC 2710 (MLDv1):
"To be valid, the Query message MUST
come from a link-local IPv6 Source Address, be at least 24 octets
long, and have a correct MLD checksum."
Same goes for RFC 3810.
And also it can be seen as a requirement in ipv6_mc_check_mld_query()
which is used by the bridge to validate the message before processing
it. Thus any queries with :: source address won't be processed anyway.
So just remove the check for zero IPv6 source address from the query
processing function.

selftests/ftrace: Fix synthetic event test to delete event correctly
Fix the synthetic event test case to remove event correctly.
If redirecting command to synthetic_event file without append
mode, it cleans up all existing events and execute (parse) the
command. This means "delete event" always fails to find the
target event.
Since previous synthetic event has a bug which doesn't return
-ENOENT even if it fails to find the deleting event, this test
passed. But fixing that bug, this test fails because this test
itself has a bug.
This fixes that bug by trying to delete event right after
adding an event, and use append mode redirection ('>>') instead
of normal redirection ('>').

modpost: Create macro to avoid variable shadowing
Create DEF_FIELD_ADDR_VAR as a more generic version of the DEF_FIELD_ADD macro, allowing usage of a variable name other than the struct element name. Also, sets DEF_FIELD_ADDR as a specific usage of DEF_FILD_ADDR_VAR in which the var name is the same as the struct element name. Then, makes use of DEF_FIELD_ADDR_VAR to create a variable of another name, in order to avoid variable shadowing.

parisc: Fix A500 boot crash
I believe the following change will fix the cache/TLB inconsistency observed by Meelis. After changing the page table entries, we need to flush the cache and TLB to ensure that we don't have any stale PTE values in the cache or TLB. The alternative patching is done after all CPUs are running. Thus, we need to flush the whole cache and TLB. I included the init section in the range modified by map_pages as suggested by Helge. Some routines in the init section may require patching. Signed-off-by: John David Anglin <dave.anglin@bell.net> Signed-off-by: Helge Deller <deller@gmx.de> |

HID: we do not randomly make new drivers 'default y'
.. even when that "default y" is hidden syntactically as a default !EXPERT it's wrong. The only reason something should be 'default y' is if it used to be built-in, and it was made configurable, and the 'default y' is just retaining the status quo. Altheratively, the hardware for the driver has become _so_ common that it really makes sense for everybody to build it. Finally, one possible reason for 'default y' is because the option is not enabling any new code at all, but is just enabling other options (the networking people do this for vendor options, for example, so that you can disable whole vendors at a time). Clearly, none of these cases hold for the BigBen Interactive Kids' gamepad, and HID_BIGBEN_FF should thus most definitely not default to on for everybody.

tracing: Have stack tracer trace full stack
The stack tracer traces every function call checking the current stack (in non interrupt context), looking for the deepest stack, and saving it when it finds a new max depth. The problem is that it calls save_stack_trace(), and with the new ORC unwinder, it can skip too much. As it looks at the ip of the function call in the backtrace to find where it should start, it doesn't need to skip anything. The stack trace selftest would fail when the kernel was complied with the ORC UNDWINDER enabled. Without skipping functions when doing the stack trace, it now passes again.

hugetlbfs: dirty pages as they are added to pagecache
Some test systems were experiencing negative huge page reserve counts and
incorrect file block counts. This was traced to /proc/sys/vm/drop_caches
removing clean pages from hugetlbfs file pagecaches. When non-hugetlbfs
explicit code removes the pages, the appropriate accounting is not
performed.
This can be recreated as follows:
fallocate -l 2M /dev/hugepages/foo
echo 1 > /proc/sys/vm/drop_caches
fallocate -l 2M /dev/hugepages/foo
grep -i huge /proc/meminfo
AnonHugePages: 0 kB
ShmemHugePages: 0 kB
HugePages_Total: 2048
HugePages_Free: 2047
HugePages_Rsvd: 18446744073709551615
HugePages_Surp: 0
Hugepagesize: 2048 kB
Hugetlb: 4194304 kB
ls -lsh /dev/hugepages/foo
4.0M -rw-r--r--. 1 root root 2.0M Oct 17 20:05 /dev/hugepages/foo
To address this issue, dirty pages as they are added to pagecache. This
can easily be reproduced with fallocate as shown above. Read faulted
pages will eventually end up being marked dirty. But there is a window
where they are clean and could be impacted by code such as drop_caches.
So, just dirty them all as they are added to the pagecache.

mm: split SWP_FILE into SWP_ACTIVATED and SWP_FS
The SWP_FILE flag serves two purposes: to make swap_{read,write}page() go
through the filesystem, and to make swapoff() call ->swap_deactivate().
For Btrfs, we want the latter but not the former, so split this flag into
two. This makes us always call ->swap_deactivate() if ->swap_activate()
succeeded, not just if it didn't add any swap extents itself.
This also resolves the issue of the very misleading name of SWP_FILE,
which is only used for swap files over NFS.

There should be no cache left by the time we overwrite the old transhuge pmd with the new one. It's already too late to flush through the virtual address because we already copied the page data to the new physical address. So flush the cache before the data copy.

mm: thp: fix mmu_notifier in migrate_misplaced_transhuge_page()
change_huge_pmd() after arming the numa/protnone pmd doesn't flush the TLB
right away. do_huge_pmd_numa_page() flushes the TLB before calling
migrate_misplaced_transhuge_page(). By the time do_huge_pmd_numa_page()
runs some CPU could still access the page through the TLB.
change_huge_pmd() before arming the numa/protnone transhuge pmd calls
mmu_notifier_invalidate_range_start(). So there's no need of
mmu_notifier_invalidate_range_start()/mmu_notifier_invalidate_range_only_end()
sequence in migrate_misplaced_transhuge_page() too, because by the time
migrate_misplaced_transhuge_page() runs, the pmd mapping has already been
invalidated in the secondary MMUs. It has to or if a secondary MMU can
still write to the page, the migrate_page_copy() would lose data.
However an explicit mmu_notifier_invalidate_range() is needed before
migrate_misplaced_transhuge_page() starts copying the data of the
transhuge page or the below can happen for MMU notifier users sharing the
primary MMU pagetables and only implementing ->invalidate_range:
CPU0 CPU1 GPU sharing linux pagetables using
only ->invalidate_range
----------- ------------ ---------
GPU secondary MMU writes to the page
mapped by the transhuge pmd
change_pmd_range()
mmu..._range_start()
->invalidate_range_start() noop
change_huge_pmd()
set_pmd_at(numa/protnone)
pmd_unlock()
do_huge_pmd_numa_page()
CPU TLB flush globally (1)
CPU cannot write to page
migrate_misplaced_transhuge_page()
GPU writes to the page...
migrate_page_copy()
...GPU stops writing to the page
CPU TLB flush (2)
mmu..._range_end() (3)
->invalidate_range_stop() noop
->invalidate_range()
GPU secondary MMU is invalidated
and cannot write to the page anymore
(too late)
Just like we need a CPU TLB flush (1) because the TLB flush (2) arrives
too late, we also need a mmu_notifier_invalidate_range() before calling
migrate_misplaced_transhuge_page(), because the ->invalidate_range() in
(3) also arrives too late.
This requirement is the result of the lazy optimization in
change_huge_pmd() that releases the pmd_lock without first flushing the
TLB and without first calling mmu_notifier_invalidate_range().
Even converting the removed mmu_notifier_invalidate_range_only_end() into
a mmu_notifier_invalidate_range_end() would not have been enough to fix
this, because it run after migrate_page_copy().
After the hugepage data copy is done migrate_misplaced_transhuge_page()
can proceed and call set_pmd_at without having to flush the TLB nor any
secondary MMUs because the secondary MMU invalidate, just like the CPU TLB
flush, has to happen before the migrate_page_copy() is called or it would
be a bug in the first place (and it was for drivers using
->invalidate_range()).
KVM is unaffected because it doesn't implement ->invalidate_range().
The standard PAGE_SIZEd migrate_misplaced_page is less accelerated and
uses the generic migrate_pages which transitions the pte from
numa/protnone to a migration entry in try_to_unmap_one() and flushes TLBs
and all mmu notifiers there before copying the page.

mm: thp: fix MADV_DONTNEED vs migrate_misplaced_transhuge_page race condition
Patch series "migrate_misplaced_transhuge_page race conditions". Aaron found a new instance of the THP MADV_DONTNEED race against pmdp_clear_flush* variants, that was apparently left unfixed. While looking into the race found by Aaron, I may have found two more issues in migrate_misplaced_transhuge_page. These race conditions would not cause kernel instability, but they'd corrupt userland data or leave data non zero after MADV_DONTNEED. I did only minor testing, and I don't expect to be able to reproduce this (especially the lack of ->invalidate_range before migrate_page_copy, requires the latest iommu hardware or infiniband to reproduce). The last patch is noop for x86 and it needs further review from maintainers of archs that implement flush_cache_range() (not in CC yet). To avoid confusion, it's not the first patch that introduces the bug fixed in the second patch, even before removing the pmdp_huge_clear_flush_notify, that _notify suffix was called after migrate_page_copy already run. This patch (of 3): This is a corollary of |

mm/kasan/quarantine.c: make quarantine_lock a raw_spinlock_t
The static lock quarantine_lock is used in quarantine.c to protect the quarantine queue datastructures. It is taken inside quarantine queue manipulation routines (quarantine_put(), quarantine_reduce() and quarantine_remove_cache()), with IRQs disabled. This is not a problem on a stock kernel but is problematic on an RT kernel where spin locks are sleeping spinlocks, which can sleep and can not be acquired with disabled interrupts. Convert the quarantine_lock to a raw spinlock_t. The usage of quarantine_lock is confined to quarantine.c and the work performed while the lock is held is used for debug purpose.

mm/gup: cache dev_pagemap while pinning pages
Getting pages from ZONE_DEVICE memory needs to check the backing device's live-ness, which is tracked in the device's dev_pagemap metadata. This metadata is stored in a radix tree and looking it up adds measurable software overhead. This patch avoids repeating this relatively costly operation when dev_pagemap is used by caching the last dev_pagemap while getting user pages. The gup_benchmark kernel self test reports this reduces time to get user pages to as low as 1/3 of the previous time.
