Pull btrfs fix from David Sterba:
"One more patch that we'd like to get to 5.12 before release.
It's changing where and how the superblock is stored in the zoned
mode. It is an on-disk format change but so far there are no
implications for users as the proper mkfs support hasn't been merged
and is waiting for the kernel side to settle.
Until now, the superblocks were derived from the zone index, but zone
size can differ per device. This is changed to be based on fixed
offset values, to make it independent of the device zone size.
The work on that got a bit delayed, we discussed the exact locations
to support potential device sizes and usecases. (Partially delayed
also due to my vacation.) Having that in the same release where the
zoned mode is declared usable is highly desired, there are userspace
projects that need to be updated to recognize the feature. Pushing
that to the next release would make things harder to test"

git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu
Pull percpu fix from Dennis Zhou:
"This contains a fix for sporadically failing atomic percpu
allocations.
I only caught it recently while I was reviewing a new series [1] and
simultaneously saw reports by btrfs in xfstests [2] and [3].
In v5.9, memcg accounting was extended to percpu done by adding a
second type of chunk. I missed an interaction with the free page float
count used to ensure we can support atomic allocations. If one type of
chunk has no free pages, but the other has enough to satisfy the free
page float requirement, we will not repopulate the free pages for the
former type of chunk. This led to the sporadically failing atomic
allocations"

Moves the location of the superblock logging zones. The new locations of
the logging zones are now determined based on fixed block addresses
instead of on fixed zone numbers.
The old placement method based on fixed zone numbers causes problems when
one needs to inspect a file system image without access to the drive zone
information. In such case, the super block locations cannot be reliably
determined as the zone size is unknown. By locating the superblock logging
zones using fixed addresses, we can scan a dumped file system image without
the zone information since a super block copy will always be present at or
after the fixed known locations.
Introduce the following three pairs of zones containing fixed offset
locations, regardless of the device zone size.
- primary superblock: offset 0B (and the following zone)
- first copy: offset 512G (and the following zone)
- Second copy: offset 4T (4096G, and the following zone)
If a logging zone is outside of the disk capacity, we do not record the
superblock copy.
The first copy position is much larger than for a non-zoned filesystem,
which is at 64M. This is to avoid overlapping with the log zones for
the primary superblock. This higher location is arbitrary but allows
supporting devices with very large zone sizes, plus some space around in
between.
Such large zone size is unrealistic and very unlikely to ever be seen in
real devices. Currently, SMR disks have a zone size of 256MB, and we are
expecting ZNS drives to be in the 1-4GB range, so this limit gives us
room to breathe. For now, we only allow zone sizes up to 8GB. The
maximum zone size that would still fit in the space is 256G.
The fixed location addresses are somewhat arbitrary, with the intent of
maintaining superblock reliability for smaller and larger devices, with
the preference for the latter. For this reason, there are two superblocks
under the first 1T. This should cover use cases for physical devices and
for emulated/device-mapper devices.
The superblock logging zones are reserved for superblock logging and
never used for data or metadata blocks. Note that we only reserve the
two zones per primary/copy actually used for superblock logging. We do
not reserve the ranges of zones possibly containing superblocks with the
largest supported zone size (0-16GB, 512G-528GB, 4096G-4112G).
The zones containing the fixed location offsets used to store
superblocks on a non-zoned volume are also reserved to avoid confusion.

On systems with KPTI enabled, we can currently observe the following
warning:
BUG: using smp_processor_id() in preemptible

While it normally makes sense to require preemption to be off, so that
the expected CPU's TLB is flushed and not another, in our case it really
is best-effort (see comments in kfence_protect_page()).
Avoid the warning by disabling preemption around flush_tlb_one_kernel().

hungtask in below case:
DIO: Checkpoint:
get addr A(at boundary), merge into BIO,
no submit because boundary missing
flush dirty data(get addr A+1), wait IO(A+1)
writeback timeout, because DIO(A) didn't submit
get addr A+2 fail, because checkpoint is doing
dio_send_cur_page() may clear sdio->boundary, so prevent it from missing
a boundary.

ia64 has two stacks:
- memory stack (or stack), pointed at by by r12
- register backing store (register stack), pointed at by
ar.bsp/ar.bspstore with complications around dirty
register frame on CPU.
In [1] Dmitry noticed that PTRACE_GET_SYSCALL_INFO returns the register
stack instead memory stack.
The bug comes from the fact that user_stack_pointer() and
current_user_stack_pointer() don't return the same register:
ulong user_stack_pointer(struct pt_regs *regs) { return regs->ar_bspstore; }
#define current_user_stack_pointer() (current_pt_regs()->r12)
The change gets both back in sync.
I think ptrace(PTRACE_GET_SYSCALL_INFO) is the only affected user by
this bug on ia64.
The change fixes 'rt_sigreturn.gen.test' strace test where it was
observed initially.

The following deadlock is detected:
truncate -> setattr path is waiting for pending direct IO to be done (inode->i_dio_count become zero) with inode->i_rwsem held (down_write).
PID: 14827 TASK: ffff881686a9af80 CPU: 20 COMMAND: "ora_p005_hrltd9"
#0 __schedule at ffffffff818667cc

#9 entry_SYSCALL_64_after_hwframe at ffffffff81a001ad
dio completion path is going to complete one direct IO (decrement
inode->i_dio_count), but before that it hung at locking inode->i_rwsem:
#0 __schedule+700 at ffffffff818667cc
#1 schedule+54 at ffffffff81866de6

#11 kthread+261 at ffffffff810b7fd5
#12 ret_from_fork+62 at ffffffff81a0035e
Thus above forms ABBA deadlock. The same deadlock was mentioned in
upstream commit 28f5a8a7c033 ("ocfs2: should wait dio before inode lock
in ocfs2_setattr()"). It seems that that commit only removed the
cluster lock (the victim of above dead lock) from the ABBA deadlock
party.
End-user visible effects: Process hang in truncate -> ocfs2_setattr path
and other processes hang at ocfs2_dio_end_io_write path.

LLVM changed the expected function signature for llvm_gcda_emit_function()
in the clang-11 release. Users of clang-11 or newer may have noticed
their kernels producing invalid coverage information:
$ llvm-cov gcov -a -c -u -f -b <input>.gcda -- gcno=<input>.gcno
1 <func>: checksum mismatch, \
(<lineno chksum A>, <cfg chksum B>) != (<lineno chksum A>, <cfg chksum C>)
2 Invalid .gcda File!
...
Fix up the function signatures so calling this function interprets its
parameters correctly and computes the correct cfg checksum. In
particular, in clang-11, the additional checksum is no longer optional.

Commit cb9f753a3731 ("mm: fix races between swapoff and flush dcache")
updated flush_dcache_page implementations on several architectures to
use page_mapping_file() in order to avoid races between page_mapping()
and swapoff().
This update missed arch/nds32 and there is a possibility of a race
there.
Replace page_mapping() with page_mapping_file() in nds32 implementation
of flush_dcache_page().

When we do coredump for user process signal, this may be an SIGBUS signal
with BUS_MCEERR_AR or BUS_MCEERR_AO code, which means this signal is
resulted from ECC memory fail like SRAR or SRAO, we expect the memory
recovery work is finished correctly, then the get_dump_page() will not
return the error page as its process pte is set invalid by
memory_failure().
But memory_failure() may fail, and the process's related pte may not be
correctly set invalid, for current code, we will return the poison page,
get it dumped, and then lead to system panic as its in kernel code.
So check the poison status in get_dump_page(), and if TRUE, return NULL.
There maybe other scenario that is also better to check the posion status
and not to panic, so make a wrapper for this check, Thanks to David's
suggestion(<david@redhat.com>).

napi_disable() is subject to an hangup, when the threaded
mode is enabled and the napi is under heavy traffic.
If the relevant napi has been scheduled and the napi_disable()
kicks in before the next napi_threaded_wait() completes - so
that the latter quits due to the napi_disable_pending() condition,
the existing code leaves the NAPI_STATE_SCHED bit set and the
napi_disable() loop waiting for such bit will hang.
This patch addresses the issue by dropping the NAPI_STATE_DISABLE
bit test in napi_thread_wait(). The later napi_threaded_poll()
iteration will take care of clearing the NAPI_STATE_SCHED.
This also addresses a related problem reported by Jakub:
before this patch a napi_disable()/napi_enable() pair killed
the napi thread, effectively disabling the threaded mode.
On the patched kernel napi_disable() simply stops scheduling
the relevant thread.
v1 -> v2:
- let the main napi_thread_poll() loop clear the SCHED bit

The ethernet frame length is calculated incorrectly. Depending on
the value of RX_HEAD_PADDING, this may result in ethernet frames
that are too short (cut off at the end), or too long (garbage added
to the end).
Fix by calculating the ethernet frame length correctly. For added
clarity, use the ETH_FCS_LEN constant in the calculation.

not configured by #gpio-cells and can't be parsed along with other

When we suspend the VM, the VDPA interface will be reset. When the VM is
resumed again, clear_virtqueues() will clear the available and used
indices resulting in hardware virqtqueue objects becoming out of sync.
We can avoid this function alltogether since qemu will clear them if
required, e.g. when the VM went through a reboot.
Moreover, since the hw available and used indices should always be
identical on query and should be restored to the same value same value
for virtqueues that complete in order, we set the single value provided
by set_vq_state(). In get_vq_state() we return the value of hardware
used index.

drivers/usb/core/hub.c: usb_new_device() contains the following:
/* By default, forbid autosuspend for all devices. It will be
* allowed for hubs during binding.
*/
usb_disable_autosuspend(udev);
So for anything which is not a hub, such as btusb devices, autosuspend is
disabled by default and we must call usb_enable_autosuspend(udev) to
enable it.
This means that the "Fix the autosuspend enable and disable" commit,
which drops the usb_enable_autosuspend() call when the enable_autosuspend
module option is true, is completely wrong, revert it.

nr_empty_pop_pages is used to guarantee that there are some free
populated pages to satisfy atomic allocations. Accounted and
non-accounted allocations are using separate sets of chunks,
so both need to have a surplus of empty pages.
This commit makes pcpu_nr_empty_pop_pages and the corresponding logic
per chunk type.
[Dennis]
This issue came up as I was reviewing [1] and realized I missed this.

Commit
334872a09198 ("x86/traps: Attempt to fixup exceptions in vDSO before signaling")
added return statements which bypass calling cond_local_irq_disable().
According to
ca4c6a9858c2 ("x86/traps: Make interrupt enable/disable symmetric in C code"),
cond_local_irq_disable() is needed because the asm return code no longer
disables interrupts. Follow the existing code as an example to use "goto
exit" instead of "return" statement.

====================
lantiq: GSWIP: two more fixes
after my last patch got accepted and is now in net as commit
3e6fdeb28f4c33 ("net: dsa: lantiq_gswip: Let GSWIP automatically set
the xMII clock") [0] some more people from the OpenWrt community
(many thanks to everyone involved) helped test the GSWIP driver: [1]
It turns out that the previous fix does not work for all boards.
There's no regression, but it doesn't fix as many problems as I
thought. This is why two more fixes are needed:
- the first one solves many (four known but probably there are
a few extra hidden ones) reported bugs with the GSWIP where no
traffic would flow. Not all circumstances are fully understood
but testing shows that switching away from PHY auto polling
solves all of them
- while investigating the different problems which are addressed
by the first patch some small issues with the existing code were
found. These are addressed by the second patch
Changes since v1 at [0]:
- Don't configure the link parameters in gswip_phylink_mac_config
(as we're using the "modern" way in gswip_phylink_mac_link_up).
Thanks to Andrew for the hint with the phylink documentation.
- Clarify that GSWIP_MII_CFG_RMII_CLK is ignored by the hardware in
the description of the second patch as suggested by Hauke
- Don't set GSWIP_MII_CFG_RGMII_IBS in the second patch as we don't
have any hardware available for testing this. The patch
description now also reflects this.
- Added Andrew's Reviewed-by to the first patch (thank you!)

There are a few more bits in the GSWIP_MII_CFG register for which we
did rely on the boot-loader (or the hardware defaults) to set them up
properly.
For some external RMII PHYs we need to select the GSWIP_MII_CFG_RMII_CLK
bit and also we should un-set it for non-RMII PHYs. The
GSWIP_MII_CFG_RMII_CLK bit is ignored for other PHY connection modes.
The GSWIP IP also supports in-band auto-negotiation for RGMII PHYs when
the GSWIP_MII_CFG_RGMII_IBS bit is set. Clear this bit always as there's
no known hardware which uses this (so it is not tested yet).
Clear the xMII isolation bit when set at initialization time if it was
previously set by the bootloader. Not doing so could lead to no traffic
(neither RX nor TX) on a port with this bit set.
While here, also add the GSWIP_MII_CFG_RESET bit. We don't need to
manage it because this bit is self-clearning when set. We still add it
here to get a better overview of the GSWIP_MII_CFG register.

PHY auto polling on the GSWIP hardware can be used so link changes
(speed, link up/down, etc.) can be detected automatically. Internally
GSWIP reads the PHY's registers for this functionality. Based on this
automatic detection GSWIP can also automatically re-configure it's port
settings. Unfortunately this auto polling (and configuration) mechanism
seems to cause various issues observed by different people on different
devices:
- FritzBox 7360v2: the two Gbit/s ports (connected to the two internal
PHY11G instances) are working fine but the two Fast Ethernet ports
(using an AR8030 RMII PHY) are completely dead (neither RX nor TX are
received). It turns out that the AR8030 PHY sets the BMSR_ESTATEN bit
as well as the ESTATUS_1000_TFULL and ESTATUS_1000_XFULL bits. This
makes the PHY auto polling state machine (rightfully?) think that the
established link speed (when the other side is Gbit/s capable) is
1Gbit/s.
- None of the Ethernet ports on the Zyxel P-2812HNU-F1 (two are
connected to the internal PHY11G GPHYs while the other three are
external RGMII PHYs) are working. Neither RX nor TX traffic was
observed. It is not clear which part of the PHY auto polling state-
machine caused this.
- FritzBox 7412 (only one LAN port which is connected to one of the
internal GPHYs running in PHY22F / Fast Ethernet mode) was seeing
random disconnects (link down events could be seen). Sometimes all
traffic would stop after such disconnect. It is not clear which part
of the PHY auto polling state-machine cauased this.
- TP-Link TD-W9980 (two ports are connected to the internal GPHYs
running in PHY11G / Gbit/s mode, the other two are external RGMII
PHYs) was affected by similar issues as the FritzBox 7412 just without
the "link down" events
Switch to software based configuration instead of PHY auto polling (and
letting the GSWIP hardware configure the ports automatically) for the
following link parameters:
- link up/down
- link speed
- full/half duplex
- flow control (RX / TX pause)
After a big round of manual testing by various people (who helped test
this on OpenWrt) it turns out that this fixes all reported issues.
Additionally it can be considered more future proof because any
"quirk" which is implemented for a PHY on the driver side can now be
used with the GSWIP hardware as well because Linux is in control of the
link parameters.
As a nice side-effect this also solves a problem where fixed-links were
not supported previously because we were relying on the PHY auto polling
mechanism, which cannot work for fixed-links as there's no PHY from
where it can read the registers. Configuring the link settings on the
GSWIP ports means that we now use the settings from device-tree also for
ports with fixed-links.

With recent changes that separated action module load from action
initialization tcf_action_init() function error handling code was modified
to manually release the loaded modules if loading/initialization of any
further action in same batch failed. For the case when all modules
successfully loaded and some of the actions were initialized before one of
them failed in init handler. In this case for all previous actions the
module will be released twice by the error handler: First time by the loop
that manually calls module_put() for all ops, and second time by the action
destroy code that puts the module after destroying the action.
Reproduction:
$ sudo tc actions add action simple sdata \"2\" index 2
$ sudo tc actions add action simple sdata \"1\" index 1 \
action simple sdata \"2\" index 2
RTNETLINK answers: File exists
We have an error talking to the kernel

$ sudo tc actions add action simple sdata \"2\" index 2
Error: Failed to load TC action module.
We have an error talking to the kernel
$ lsmod | grep simple
act_simple 20480 -1
Fix the issue by modifying module reference counting handling in action
initialization code:
- Get module reference in tcf_idr_create() and put it in tcf_idr_release()
instead of taking over the reference held by the caller.
- Modify users of tcf_action_init_1() to always release the module
reference which they obtain before calling init function instead of
assuming that created action takes over the reference.
- Finally, modify tcf_action_init_1() to not release the module reference
when overwriting existing action as this is no longer necessary since both
upper and lower layers obtain and manage their own module references
independently.

Action init code increments reference counter when it changes an action.
This is the desired behavior for cls API which needs to obtain action
reference for every classifier that points to action. However, act API just
needs to change the action and releases the reference before returning.
This sequence breaks when the requested action doesn't exist, which causes
act API init code to create new action with specified index, but action is
still released before returning and is deleted (unless it was referenced
concurrently by cls API).
Reproduction:
$ sudo tc actions ls action gact
$ sudo tc actions change action gact drop index 1
$ sudo tc actions ls action gact
Extend tcf_action_init() to accept 'init_res' array and initialize it with
action->ops->init() result. In tcf_action_add() remove pointers to created
actions from actions array before passing it to tcf_action_put_many().

WARNING: at fs/io_uring.c:8578 io_ring_exit_work.cold+0x0/0x18
As reissuing is now passed back by REQ_F_REISSUE and kiocb_done()
internally uses __io_complete_rw(), it may stop after setting the flag
so leaving a dangling request.
There are tricky edge cases, e.g. reading beyound file, boundary, so
the easiest way is to hand code reissue in kiocb_done() as
__io_complete_rw() was doing for us before.

In ice_suspend(), ice_clear_interrupt_scheme() is called, and then
irq_free_descs() will be eventually called to free irq and its descriptor.
In ice_resume(), ice_init_interrupt_scheme() is called to allocate new
irqs. However, in ice_rebuild_arfs(), struct irq_glue and struct cpu_rmap
maybe cannot be freed, if the irqs that released in ice_suspend() were
reassigned to other devices, which makes irq descriptor's affinity_notify
lost.
So call ice_free_cpu_rx_rmap() before ice_clear_interrupt_scheme(), which
can make sure all irq_glue and cpu_rmap can be correctly released before
corresponding irq and descriptor are released.
Fix the following memory leak.

Pull close_range() fix from Christian Brauner:
"Syzbot reported a bug in close_range.
Debugging this showed we didn't recalculate the current maximum fd
number for CLOSE_RANGE_UNSHARE | CLOSE_RANGE_CLOEXEC after we unshared
the file descriptors table. As a result, max_fd could exceed the
current fdtable maximum causing us to set excessive bits.
As a concrete example, let's say the user requested everything from fd
4 to ~0UL to be closed and their current fdtable size is 256 with
their highest open fd being 4. With CLOSE_RANGE_UNSHARE the caller
will end up with a new fdtable which has room for 64 file descriptors
since that is the lowest fdtable size we accept. But now max_fd will
still point to 255 and needs to be adjusted. Fix this by retrieving
the correct maximum fd value in __range_cloexec().
I've carried this fix for a little while but since there was no
linux-next release over easter I waited until now.
With this change close_range() can be further simplified but imho we
are in no hurry to do that and so I'll defer this for the 5.13 merge

Pull umount fix from Al Viro:
"Brown paperbag time: dumb braino in the series that went into 5.7
broke the 'don't step into ->d_weak_revalidate() when umount(2) looks
the victim up' behaviour.
Spotted only now - saw
if (!err && unlikely(nd->flags & LOOKUP_MOUNTPOINT)) {
err = handle_lookup_down(nd);
nd->flags &= ~LOOKUP_JUMPED; // no d_weak_revalidate(), please...
}
and went "why do we clear that flag here - nothing below that point is
going to check it anyway" / "wait a minute, what is it doing *after*
complete_walk() (which is where we check that flag and call
->d_weak_revalidate())" / "how could that possibly _not_ break?",
followed by reproducing the breakage and verifying that the obvious
fix of that braino does, indeed, fix it.
The reproducer is (assuming that $DIR exists and is exported r/w to
localhost)
mkdir $DIR/a
mkdir /tmp/foo
mount --bind /tmp/foo /tmp/foo
mkdir /tmp/foo/a
mkdir /tmp/foo/b
mount -t nfs4 localhost:$DIR/a /tmp/foo/a
mount -t nfs4 localhost:$DIR /tmp/foo/b
rmdir /tmp/foo/b/a
umount /tmp/foo/b
umount /tmp/foo/a
umount -l /tmp/foo # will get everything under /tmp/foo, no matter what
Correct behaviour is successful umount; broken kernels (5.7-rc1 and
later) get
umount.nfs4: /tmp/foo/a: Stale file handle
Note that bind mount is there to be able to recover - on broken
kernels we'd get stuck with impossible-to-umount filesystem if not for
that.
FWIW, that braino had been posted for review back then, at least
twice. Unfortunately, the call of complete_walk() was outside of diff
context, so the bogosity hadn't been immediately obvious from the
patch alone ;-/"

The branch displacement logic in the BPF JIT compilers for x86 assumes
that, for any generated branch instruction, the distance cannot
increase between optimization passes.
But this assumption can be violated due to how the distances are
computed. Specifically, whenever a backward branch is processed in
do_jit(), the distance is computed by subtracting the positions in the
machine code from different optimization passes. This is because part
of addrs[] is already updated for the current optimization pass, before
the branch instruction is visited.
And so the optimizer can expand blocks of machine code in some cases.
This can confuse the optimizer logic, where it assumes that a fixed
point has been reached for all machine code blocks once the total
program size stops changing. And then the JIT compiler can output
abnormal machine code containing incorrect branch displacements.
To mitigate this issue, we assert that a fixed point is reached while
populating the output image. This rejects any problematic programs.
The issue affects both x86-32 and x86-64. We mitigate separately to
ease backporting.

Right now, if a call to kvm_tdp_mmu_zap_sp returns false, the caller
will skip the TLB flush, which is wrong. There are two ways to fix
it:
- since kvm_tdp_mmu_zap_sp will not yield and therefore will not flush
the TLB itself, we could change the call to kvm_tdp_mmu_zap_sp to
use "flush |= ..."
- or we can chain the flush argument through kvm_tdp_mmu_zap_sp down
to __kvm_tdp_mmu_zap_gfn_range. Note that kvm_tdp_mmu_zap_sp will
neither yield nor flush, so flush would never go from true to
false.
This patch does the former to simplify application to stable kernels,
and to make it further clearer that kvm_tdp_mmu_zap_sp will not flush.

Normally, TXQs have
txq->tid = tid;
txq->ac = ieee80211_ac_from_tid(tid);
However, the special management TXQ actually has
txq->tid = IEEE80211_NUM_TIDS; // 16
txq->ac = IEEE80211_AC_VO;
This makes sense, but ieee80211_ac_from_tid(16) is the same
as ieee80211_ac_from_tid(0) which is just IEEE80211_AC_BE.
Now, normally this is fine. However, if the netdev queues
were stopped, then the code in ieee80211_tx_dequeue() will
propagate the stop from the interface (vif->txqs_stopped[])
if the AC 2 (ieee80211_ac_from_tid(txq->tid)) is marked as
stopped. On wake, however, __ieee80211_wake_txqs() will wake
the TXQ if AC 0 (txq->ac) is woken up.
If a driver stops all queues with ieee80211_stop_tx_queues()
and then wakes them again with ieee80211_wake_tx_queues(),
the ieee80211_wake_txqs() tasklet will run to resync queue
and TXQ state. If all queues were woken, then what'll happen
is that _ieee80211_wake_txqs() will run in order of HW queues
0-3, typically (and certainly for iwlwifi) corresponding to
ACs 0-3, so it'll call __ieee80211_wake_txqs() for each AC in
order 0-3.
When __ieee80211_wake_txqs() is called for AC 0 (VO) that'll
wake up the management TXQ (remember its tid is 16), and the
driver's wake_tx_queue() will be called. That tries to get a
frame, which will immediately *stop* the TXQ again, because
now we check against AC 2, and AC 2 hasn't yet been marked as
woken up again in sdata->vif.txqs_stopped[] since we're only
in the __ieee80211_wake_txqs() call for AC 0.
Thus, the management TXQ will never be started again.
Fix this by checking txq->ac directly instead of calculating
the AC as ieee80211_ac_from_tid(txq->tid).

Recompiling with the new extended version of struct rfkill_event
broke systemd in *two* ways:
- It used "sizeof(struct rfkill_event)" to read the event, but
then complained if it actually got something != 8, this broke
it on new kernels (that include the updated API);
- It used sizeof(struct rfkill_event) to write a command, but
didn't implement the intended expansion protocol where the
kernel returns only how many bytes it accepted, and errored
out due to the unexpected smaller size on kernels that didn't
include the updated API.
Even though systemd has now been fixed, that fix may not be always
deployed, and other applications could potentially have similar
issues.
As such, in the interest of avoiding regressions, revert the
default API "struct rfkill_event" back to the original size.
Instead, add a new "struct rfkill_event_ext" that extends it by
the new field, and even more clearly document that applications
should be prepared for extensions in two ways:
* write might only accept fewer bytes on older kernels, and
will return how many to let userspace know which data may
have been ignored;
* read might return anything between 8 (the original size) and
whatever size the application sized its buffer at, indicating
how much event data was supported by the kernel.
Perhaps that will help avoid such issues in the future and we
won't have to come up with another version of the struct if we
ever need to extend it again.
Applications that want to take advantage of the new field will
have to be modified to use struct rfkill_event_ext instead now,
which comes with the danger of them having already been updated
to use it from 'struct rfkill_event', but I found no evidence
of that, and it's still relatively new.

In some race conditions, with more clients and traffic configuration,
below crash is seen when making the interface down. sta->fast_rx wasn't
cleared when STA gets removed from 4-addr AP_VLAN interface. The crash is
due to try accessing 4-addr AP_VLAN interface's net_device (fast_rx->dev)
which has been deleted already.
Resolve this by clearing sta->fast_rx pointer when STA removes
from a 4-addr VLAN.

This patch adds the specific quirk for the device to restore the COEF

Since commit 1b8b31a2e612 ("selinux: convert policy read-write lock to
RCU"), there is a small window during policy load where the new policy
pointer has already been installed, but some threads may still be
holding the old policy pointer in their read-side RCU critical sections.
This means that there may be conflicting attempts to add a new SID entry
to both tables via sidtab_context_to_sid().
See also (and the rest of the thread):
https://lore.kernel.org/selinux/CAFqZXNvfux46_f8gnvVvRYMKoes24nwm2n3sPbMjrB8vKTW00g@mail.gmail.com/
Fix this by installing the new policy pointer under the old sidtab's
spinlock along with marking the old sidtab as "frozen". Then, if an
attempt to add new entry to a "frozen" sidtab is detected, make
sidtab_context_to_sid() return -ESTALE to indicate that a new policy
has been installed and that the caller will have to abort the policy
transaction and try again after re-taking the policy pointer (which is
guaranteed to be a newer policy). This requires adding a retry-on-ESTALE
logic to all callers of sidtab_context_to_sid(), but fortunately these
are easy to determine and aren't that many.
This seems to be the simplest solution for this problem, even if it
looks somewhat ugly. Note that other places in the kernel (e.g.
do_mknodat() in fs/namei.c) use similar stale-retry patterns, so I think
it's reasonable.

Multiple ttys try to claim the same the minor number causing a double
unregistration of the same device. The first unregistration succeeds
but the next one results in a null-ptr-deref.
The get_free_serial_index() function returns an available minor number
but doesn't assign it immediately. The assignment is done by the caller
later. But before this assignment, calls to get_free_serial_index()
would return the same minor number.
Fix this by modifying get_free_serial_index to assign the minor number
immediately after one is found to be and rename it to obtain_minor()
to better reflect what it does. Similary, rename set_serial_by_index()
to release_minor() and modify it to free up the minor number of the
given hso_serial. Every obtain_minor() should have corresponding
release_minor() call.

====================
Fix link_mode derived params functionality
Currently, link_mode parameter derives 3 other link parameters, speed,
lanes and duplex, and the derived information is sent to user space.
Few bugs were found in that functionality.
First, some drivers clear the 'ethtool_link_ksettings' struct in their
get_link_ksettings() callback and cause receiving wrong link mode
information in user space. And also, some drivers can report random
values in the 'link_mode' field and cause general protection fault.
Second, the link parameters are only derived in netlink path so in ioctl
path, we don't any reasonable values.
Third, setting 'speed 10000 lanes 1' fails since the lanes parameter
wasn't set for ETHTOOL_LINK_MODE_10000baseR_FEC_BIT.
Patch #1 solves the first two problems by removing link_mode parameter
and deriving the link parameters in driver instead of ethtool.
Patch #2 solves the third one, by setting the lanes parameter for the
link_mode.
v3:
* Remove the link_mode parameter in the first patch to solve
both two issues from patch#1 and patch#2.
* Add the second patch to solve the third issue.
v2:

Lanes field is missing for ETHTOOL_LINK_MODE_10000baseR_FEC_BIT
link mode and it causes a failure when trying to set
'speed 10000 lanes 1' on Spectrum-2 machines when autoneg is set to on.
Add the lanes parameter for ETHTOOL_LINK_MODE_10000baseR_FEC_BIT
link mode.

Some drivers clear the 'ethtool_link_ksettings' struct in their
get_link_ksettings() callback, before populating it with actual values.
Such drivers will set the new 'link_mode' field to zero, resulting in
user space receiving wrong link mode information given that zero is a
valid value for the field.
Another problem is that some drivers (notably tun) can report random
values in the 'link_mode' field. This can result in a general protection
fault when the field is used as an index to the 'link_mode_params' array
[1].
This happens because such drivers implement their set_link_ksettings()
callback by simply overwriting their private copy of
'ethtool_link_ksettings' struct with the one they get from the stack,
which is not always properly initialized.
Fix these problems by removing 'link_mode' from 'ethtool_link_ksettings'
and instead have drivers call ethtool_params_from_link_mode() with the
current link mode. The function will derive the link parameters (e.g.,
speed) from the link mode and fill them in the 'ethtool_link_ksettings'
struct.
v3:
* Remove link_mode parameter and derive the link parameters in
the driver instead of passing link_mode parameter to ethtool
and derive it there.
v2:
* Introduce 'cap_link_mode_supported' instead of adding a
validity field to 'ethtool_link_ksettings' struct.

Reset MAC header in HSR Tx path. This is needed, because direct packet
transmission, e.g. by specifying PACKET_QDISC_BYPASS does not reset the MAC
header.
This has been observed using the following setup:
|$ ip link add name hsr0 type hsr slave1 lan0 slave2 lan1 supervision 45 version 1
|$ ifconfig hsr0 up
|$ ./test hsr0
The test binary is using mmap'ed sockets and is specifying the
PACKET_QDISC_BYPASS socket option.
This patch resolves the following warning on a non-patched kernel:
|[ 112.725394] ------------[ cut here ]------------
|[ 112.731418] WARNING: CPU: 1 PID: 257 at net/hsr/hsr_forward.c:560 hsr_forward_skb+0x484/0x568
|[ 112.739962] net/hsr/hsr_forward.c:560: Malformed frame (port_src hsr0)
The warning can be safely removed, because the other call sites of
hsr_forward_skb() make sure that the skb is prepared correctly.

When '--total-cycles' is specified, it supports sorting for all blocks
by 'Sampled Cycles%'. This is useful to concentrate on the globally
hottest blocks.
'Sampled Cycles%' - block sampled cycles aggregation / total sampled cycles
But in current code, it doesn't use the cycles aggregation. Part of
'cycles' counting is possibly dropped for some overlap jumps. But for
identifying the hot block, we always need the full cycles.

The issue happens when pcibus_to_node() returns NO_NUMA_NODE.
Fix this issue by moving the initialization of dd->node to hfi1_devdata
allocation and remove the other pcibus_to_node() calls in the probe path
and use dd->node instead.
Affinity logic is adjusted to use a new field dd->affinity_entry as a
guard instead of dd->node.

fdt_get_name() returns error values via a parameter pointer
instead of in function return. Fix check for this error value
in populate_node() and callers of populate_node().
Chasing up the caller tree showed callers of various functions
failing to initialize the value of pointer parameters that
can return error values. Initialize those values to NULL.
The bug was introduced by
commit e6a6928c3ea1 ("of/fdt: Convert FDT functions to use libfdt")
but this patch can not be backported directly to that commit
because the relevant code has further been restructured by
commit dfbd4c6eff35 ("drivers/of: Split unflatten_dt_node()")
The bug became visible by triggering a crash on openrisc with:
commit 79edff12060f ("scripts/dtc: Update to upstream version v1.6.0-51-g183df9e9c2b9")
as reported in:

Commit 8cdddd182bd7 ("ACPI: processor: Fix CPU0 wakeup in
acpi_idle_play_dead()") tried to fix CPU0 hotplug breakage by copying
wakeup_cpu0() + start_cpu0() logic from hlt_play_dead()//mwait_play_dead()
into acpi_idle_play_dead(). The problem is that these functions are not
exported to modules so when CONFIG_ACPI_PROCESSOR=m build fails.
The issue could've been fixed by exporting both wakeup_cpu0()/start_cpu0()
(the later from assembly) but it seems putting the whole pattern into a
new function and exporting it instead is better.

Broadcom:
- One revert for a Raspberry pi interrupt controller change that
caused a regression.
TI OMAP:
- Remove unused duplicate sha2md5_fck clock node that can race with
the OMAP4_SHA2MD5_CLKCTRL clock node for disable for unused clocks
- Add aliases for omap4/5 mmc to put the slots back into the right
order again
- Fix typo for bionic voltage controllers that accidentally use mpu
for all instances instead of mpu, core and iva
- Fix random hangs for droid4 caused by missing fix from TI Android
kernel tree to do a dummy smc call on cpuidle wakeup path
NXP i.MX:
- Fix a system failure on imx6qdl-phytec-pfla02 board when booting
from SD, by adding missing vmmc supply for SD interfaces.
- Fix address typo in i.MX8MM/Q IOMUXC_SD1_DATA0_GPIO2_IO2

This currently happens because on redirect case we do skb_set_owner_r()
with the original sock. This increments the fwd_alloc memory accounting
on the original sock. Then on redirect we may push this into the queue
of the psock we are redirecting to. When the skb is flushed from the
queue we give the memory back to the original sock. The problem is if
the original sock is destroyed/closed with skbs on another psocks queue
then the original sock will not have a way to reclaim the memory before
being destroyed. Then above warning will be thrown
sockA sockB
sk_psock_strp_read()
sk_psock_verdict_apply()
-- SK_REDIRECT --
sk_psock_skb_redirect()
skb_queue_tail(psock_other->ingress_skb..)
sk_close()
sock_map_unref()
sk_psock_put()
sk_psock_drop()
sk_psock_zap_ingress()
At this point we have torn down our own psock, but have the outstanding
skb in psock_other. Note that SK_PASS doesn't have this problem because
the sk_psock_drop() logic releases the skb, its still associated with
our psock.
To resolve lets only account for sockets on the ingress queue that are
still associated with the current socket. On the redirect case we will
check memory limits per 6fa9201a89898, but will omit fwd_alloc accounting
until skb is actually enqueued. When the skb is sent via skb_send_sock_locked
or received with sk_psock_skb_ingress memory will be claimed on psock_other.

In '4da6a196f93b1' we fixed a potential unhash loop caused when
a TLS socket in a sockmap was removed from the sockmap. This
happened because the unhash operation on the TLS ctx continued
to point at the sockmap implementation of unhash even though the
psock has already been removed. The sockmap unhash handler when a
psock is removed does the following,
void sock_map_unhash(struct sock *sk)
{
void (*saved_unhash)(struct sock *sk);
struct sk_psock *psock;
rcu_read_lock();
psock = sk_psock(sk);
if (unlikely(!psock)) {
rcu_read_unlock();
if (sk->sk_prot->unhash)
sk->sk_prot->unhash(sk);
return;
}
[...]
}
The unlikely() case is there to handle the case where psock is detached
but the proto ops have not been updated yet. But, in the above case
with TLS and removed psock we never fixed sk_prot->unhash() and unhash()
points back to sock_map_unhash resulting in a loop. To fix this we added
this bit of code,
static inline void sk_psock_restore_proto(struct sock *sk,
struct sk_psock *psock)
{
sk->sk_prot->unhash = psock->saved_unhash;
This will set the sk_prot->unhash back to its saved value. This is the
correct callback for a TLS socket that has been removed from the sock_map.
Unfortunately, this also overwrites the unhash pointer for all psocks.
We effectively break sockmap unhash handling for any future socks.
Omitting the unhash operation will leave stale entries in the map if
a socket transition through unhash, but does not do close() op.
To fix set unhash correctly before calling into tls_update. This way the
TLS enabled socket will point to the saved unhash() handler.

Xuan Zhuo reported that commit 3226b158e67c ("net: avoid 32 x truesize
under-estimation for tiny skbs") brought a ~10% performance drop.
The reason for the performance drop was that GRO was forced
to chain sk_buff (using skb_shinfo(skb)->frag_list), which
uses more memory but also cause packet consumers to go over
a lot of overhead handling all the tiny skbs.
It turns out that virtio_net page_to_skb() has a wrong strategy :
It allocates skbs with GOOD_COPY_LEN (128) bytes in skb->head, then
copies 128 bytes from the page, before feeding the packet to GRO stack.
This was suboptimal before commit 3226b158e67c ("net: avoid 32 x truesize
under-estimation for tiny skbs") because GRO was using 2 frags per MSS,
meaning we were not packing MSS with 100% efficiency.
Fix is to pull only the ethernet header in page_to_skb()
Then, we change virtio_net_hdr_to_skb() to pull the missing
headers, instead of assuming they were already pulled by callers.
This fixes the performance regression, but could also allow virtio_net
to accept packets with more than 128bytes of headers.
Many thanks to Xuan Zhuo for his report, and his tests/help.

during suspend
Some devices send (duplicate) tablet-mode events when moved around even
though the mode has not changed; and they do this even when suspended.
Change the tablet-mode event handling when priv->wakeup_mode is set to
update the switch state in case it changed and then return immediately
(without calling pm_wakeup_hard_event()) to avoid spurious wakeups.

Make sure nd->path.mnt and nd->path.dentry are always valid pointers
hostfs: fix memory handling in follow_link()
|
|
Initialize them in set_nameidata() and make sure that terminate_walk() clears them
once the pointers become potentially invalid (i.e. we leave RCU mode or drop them
in non-RCU one). Currently we have "path_init() always initializes them and nobody
accesses them outside of path_init()/terminate_walk() segments", which is asking
for trouble.
With that change we would have nd->path.{mnt,dentry}
1) always valid - NULL or pointing to currently allocated objects.
2) non-NULL while we are successfully walking
3) NULL when we are not walking at all
4) contributing to refcounts whenever non-NULL outside of RCU mode.

Some SPI host controllers do not support full-duplex SPI transfers.
The function mcp251x_spi_trans() does a full duplex transfer. It is
used in several places in the driver, where a TX half duplex transfer
is sufficient.
To fix support for half duplex SPI host controllers, this patch
introduces a new function mcp251x_spi_write() and changes all callers
that do a TX half duplex transfer to use mcp251x_spi_write().

Unfortunately, since beacon protection isn't fully available
yet, we didn't notice that there are problems with it and
that the replay detection isn't working correctly. We were
relying only on mac80211, since iwl_mvm_rx_crypto() exits
when !ieee80211_has_protected(), which is of course true for
protected (but not encrypted) management frames.
Fix this to properly detect protected (but not encrypted)
management frames and handle them - we continue to only care
about beacons since for others everything can and will be
checked in mac80211.

As the context info gen3 code is only called for >=AX210 devices
(from iwl_trans_pcie_gen2_start_fw()) the code there to set LTR
on 22000 devices cannot actually do anything (22000 < AX210).
Fix this by moving the LTR code to iwl_trans_pcie_gen2_start_fw()
where it can handle both devices. This then requires that we kick
the firmware only after that rather than doing it from the context
info code.
Note that this again had a dead branch in gen3 code, which I've
removed here.
