Pull tty / serial updates from Greg KH:
"Here is the big set of tty and serial driver patches for 5.14-rc1.
A bit more than normal, but nothing major, lots of cleanups.
Highlights are:
- lots of tty api cleanups and mxser driver cleanups from Jiri
- build warning fixes
- various serial driver updates
- coding style cleanups
- various tty driver minor fixes and updates
- removal of broken and disable r3964 line discipline (finally!)
All of these have been in linux-next for a while with no reported
issues"

Pull networking fixes from Jakub Kicinski:
"Networking fixes for 5.13-rc4, including fixes from bpf, netfilter,
can and wireless trees. Notably including fixes for the recently
announced "FragAttacks" WiFi vulnerabilities. Rather large batch,
touching some core parts of the stack, too, but nothing hair-raising.
Current release - regressions:
- tipc: make node link identity publish thread safe
- dsa: felix: re-enable TAS guard band mode
- stmmac: correct clocks enabled in stmmac_vlan_rx_kill_vid()
- stmmac: fix system hang if change mac address after interface
ifdown
Current release - new code bugs:
- mptcp: avoid OOB access in setsockopt()
- bpf: Fix nested bpf_bprintf_prepare with more per-cpu buffers
- ethtool: stats: fix a copy-paste error - init correct array size
Previous releases - regressions:
- sched: fix packet stuck problem for lockless qdisc
- net: really orphan skbs tied to closing sk
- mlx4: fix EEPROM dump support
- bpf: fix alu32 const subreg bound tracking on bitwise operations
- bpf: fix mask direction swap upon off reg sign change
- bpf, offload: reorder offload callback 'prepare' in verifier
- stmmac: Fix MAC WoL not working if PHY does not support WoL
- packetmmap: fix only tx timestamp on request
- tipc: skb_linearize the head skb when reassembling msgs
Previous releases - always broken:
- mac80211: address recent "FragAttacks" vulnerabilities
- mac80211: do not accept/forward invalid EAPOL frames
- mptcp: avoid potential error message floods
- bpf, ringbuf: deny reserve of buffers larger than ringbuf to
prevent out of buffer writes
- bpf: forbid trampoline attach for functions with variable arguments
- bpf: add deny list of functions to prevent inf recursion of tracing
programs
- tls splice: check SPLICE_F_NONBLOCK instead of MSG_DONTWAIT
- can: isotp: prevent race between isotp_bind() and
isotp_setsockopt()
- netfilter: nft_set_pipapo_avx2: Add irq_fpu_usable() check,
fallback to non-AVX2 version
Misc:
- bpf: add kconfig knob for disabling unpriv bpf by default"

As Leon Romanovsky's tips:
The definition of macro PIPELINE_DEBUG is commented more than 10 years ago
and can be seen as a dead code that should be removed.

'nj_setup' in netjet.c might fail with -EIO and in this case
'card->irq' is initialized and is bigger than zero. A subsequent call to
'nj_release' will free the irq that has not been requested.
Fix this bug by deleting the previous assignment to 'card->irq' and just
keep the assignment before 'request_irq'.

Modify return type of hfcusb_ph_info to int, so that we can pass error
value up the call stack when allocation of ph_info fails. Also change
three of four call sites to actually account for the memory failure.
The fourth, in ph_state_nt, is infeasible to change as it is in turn
called by ph_state which is used as a function pointer argument to
mISDN_initdchannel, which would necessitate changing its signature
and updating all the places where it is used (too many).
Fixes original flawed commit (38d22659803a) from the University of
Minnesota.

This reverts commit 38d22659803a033b1b66cd2624c33570c0dde77d.
Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.
Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted. It will be fixed up "correctly" in a
later kernel change.
While it looks like the original change is correct, it is not, as none
of the setup actually happens, and the error value is not propagated
upwards.

Move hw->cfg.mode and hw->addr.mode assignments from hw->ci->cfg_mode
and hw->ci->addr_mode respectively, to be before the subsequent checks
for memory IO mode (and possible ioremap calls in this case).
Also introduce ioremap error checks at both locations. This allows
resources to be properly freed on ioremap failure, as when the caller
of setup_io then subsequently calls release_io via its error path,
release_io can now correctly determine the mode as it has been set
before the ioremap call.
Finally, refactor release_io function so that it will call
release_mem_region in the memory IO case, regardless of whether or not
hw->cfg.p/hw->addr.p are NULL. This means resources are then properly
released on failure.
This properly implements the original reverted commit (d721fe99f6ad)
from the University of Minnesota, whilst also implementing the ioremap
check for the hw->ci->cfg_mode if block as well.

This reverts commit d721fe99f6ada070ae8fc0ec3e01ce5a42def0d9.
Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.
Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted. It will be fixed up "correctly" in a
later kernel change.
The original commit was incorrect, it should have never have used
"unlikely()" and if it ever does trigger, resources are left grabbed.
Given there are no users for this code around, I'll just revert this and
leave it "as is" as the odds that ioremap() will ever fail here is
horrendiously low.

Line disciplines expect a positive value or zero returned from
tty->ops->write_room (invoked by tty_write_room). So make this
assumption explicit by using unsigned int as a return value. Both of
tty->ops->write_room and tty_write_room.

This module's remove path calls del_timer(). However, that function
does not wait until the timer handler finishes. This means that the
timer handler may still be running after the driver's remove function
has finished, which would result in a use-after-free.
Fix by calling del_timer_sync(), which makes sure the timer handler
has finished, and unable to re-schedule itself.

Now that proc_ops are separate from file_operations and other operations
it easy to check all instances to have ->proc_lseek hook and remove check
in main code.
Note:
nonseekable_open() files naturally don't require ->proc_lseek.
Garbage collect pde_lseek() function.

The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
When memory is allocated in 'setup_hw()' (hfcpci.c) GFP_KERNEL can be used
because it is called from the probe function and no lock is taken.
The call chain is:
hfc_probe()
--> setup_card()
--> setup_hw()
When memory is allocated in 'inittiger()' (netjet.c) GFP_ATOMIC must be
used because a spin_lock is taken by the caller (i.e. 'nj_init_card()')
This is also consistent with the other allocations done in the function.

as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Often the function kcapi_proc_exit() has valid usage outside the exit section
and the fix is to remove the __exit annotation of kcapi_proc_exit.
Remove the incorrect __exit annotation.

The staging isdn drivers are gone, and CONFIG_BT_CMTP is now
the only user. This means a lot of the code in the subsystem
has no remaining callers and can be removed.
Change the capi user space front-end to be part of kernelcapi,
and the combined module to only be compiled if BT_CMTP is
also enabled, then remove the interfaces that have no remaining
callers.
As the notifier list and the capi_drivers list have no callers
outside of kcapi.c, the implementation gets much simpler.
Some definitions from the include/linux/*.h headers are only
needed internally and are moved to kcapi.h.

Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann:
"As part of the cleanup of some remaining y2038 issues, I came to
fs/compat_ioctl.c, which still has a couple of commands that need
support for time64_t.
In completely unrelated work, I spent time on cleaning up parts of
this file in the past, moving things out into drivers instead.
After Al Viro reviewed an earlier version of this series and did a lot
more of that cleanup, I decided to try to completely eliminate the
rest of it and move it all into drivers.
This series incorporates some of Al's work and many patches of my own,
but in the end stops short of actually removing the last part, which
is the scsi ioctl handlers. I have patches for those as well, but they
need more testing or possibly a rewrite"

Neither the old isdn4linux interface nor the newer mISDN stack
ever had working 32-bit compat mode as far as I can tell.
However, the CAPI stack has some ioctl commands that are
correctly listed in fs/compat_ioctl.c.
We can trivially move all of those into the corresponding
file that implement the native handlers by adding a compat_ioctl
redirect to that.
I did notice that treating CAPI_MANUFACTURER_CMD() as compatible
is broken, so I'm also adding a handler for that, realizing that
in all likelyhood, nobody is ever going to call it.
