ecc6ce4fdf xfrm: fix "disable_policy" on ipv4 early demux
[ Upstream commit 3a5913183aa1b14148c723bda030e6102ad73008 ]

The commit in the "Fixes" tag tried to avoid a case where policy check
is ignored due to dst caching in next hops.

However, when the traffic is locally consumed, the dst may be cached
in a local TCP or UDP socket as part of early demux. In this case the
"disable_policy" flag is not checked as ip_route_input_noref() was only
called before caching, and thus, packets after the initial packet in a
flow will be dropped if not matching policies.

Fix by checking the "disable_policy" flag also when a valid dst is
already available.

5a792c1d4d MIPS: pic32: treat port as signed integer
[ Upstream commit 648060902aa302331b5d6e4f26d8ee0761d239ab ]

get_port_from_cmdline() returns an int, yet is assigned to a char, which
is wrong in its own right, but also, with char becoming unsigned, this
poses problems, because -1 is used as an error value. Further
complicating things, fw_init_early_console() is only ever called with a
-1 argument. Fix this up by removing the unused argument from
fw_init_early_console() and treating port as a proper signed integer.

144452b421 RISC-V: vdso: Do not add missing symbols to version section in linker script
[ Upstream commit fcae44fd36d052e956e69a64642fc03820968d78 ]

Recently, ld.lld moved from '--undefined-version' to
'--no-undefined-version' as the default, which breaks the compat vDSO
build:

  ld.lld: error: version script assignment of 'LINUX_4.15' to symbol '__vdso_gettimeofday' failed: symbol not defined
  ld.lld: error: version script assignment of 'LINUX_4.15' to symbol '__vdso_clock_gettime' failed: symbol not defined
  ld.lld: error: version script assignment of 'LINUX_4.15' to symbol '__vdso_clock_getres' failed: symbol not defined

These symbols are not present in the compat vDSO or the regular vDSO for
32-bit but they are unconditionally included in the version section of
the linker script, which is prohibited with '--no-undefined-version'.

Fix this issue by only including the symbols that are actually exported
in the version section of the linker script.

5adc12d9e2 arm64/syscall: Include asm/ptrace.h in syscall_wrapper header.
[ Upstream commit acfc35cfcee5df419391671ef1a631f43feee4e3 ]

Add the same change for ARM64 as done in the commit 9440c4294160
("x86/syscall: Include asm/ptrace.h in syscall_wrapper header") to
make sure all syscalls see 'struct pt_regs' definition and resulted
BTF for '__arm64_sys_*(struct pt_regs *regs)' functions point to
actual struct.

Without this patch, the BPF verifier refuses to load a tracing prog
which accesses pt_regs.

  bpf(BPF_PROG_LOAD, {prog_type=0x1a, ...}, 128) = -1 EACCES

With this patch, we can see the correct error, which saves us time
in debugging the prog.

  bpf(BPF_PROG_LOAD, {prog_type=0x1a, ...}, 128) = 4
  bpf(BPF_RAW_TRACEPOINT_OPEN, {raw_tracepoint={name=NULL, prog_fd=4}}, 128) = -1 ENOTSUPP

Root cause is quite complex:

1) use bfq elevator for the test device.
2) create a cgroup CG
3) config blk throtl in CG

   blkg_conf_prep
    blkg_create

4) create a thread T1 and issue async io in CG:

   bio_init
    bio_associate_blkg
   ...
   submit_bio
    submit_bio_noacct
     blk_throtl_bio -> io is throttled
     // io submit is done

5) switch elevator:

   bfq_exit_queue
    blkcg_deactivate_policy
     list_for_each_entry(blkg, &q->blkg_list, q_node)
      blkg->pd[] = NULL
      // bfq policy is removed

5) thread t1 exist, then remove the cgroup CG:

   blkcg_unpin_online
    blkcg_destroy_blkgs
     blkg_destroy
      list_del_init(&blkg->q_node)
      // blkg is removed from queue list

6) switch elevator back to bfq

 bfq_init_queue
  bfq_create_group_hierarchy
   blkcg_activate_policy
    list_for_each_entry_reverse(blkg, &q->blkg_list)
     // blkg is removed from list, hence bfq policy is still NULL

7) throttled io is dispatched to bfq:

 bfq_insert_requests
  bfq_init_rq
   bfq_bic_update_cgroup
    bfq_bio_bfqg
     bfqg = blkg_to_bfqg(blkg)
     // bfqg is NULL because bfq policy is NULL

The problem is only possible in bfq because only bfq can be deactivated and
activated while queue is online, while others can only be deactivated while
the device is removed.

Fix the problem in bfq by checking if blkg is online before calling
blkg_to_bfqg().

b90e6234f5 scsi: scsi_debug: Make the READ CAPACITY response compliant with ZBC
[ Upstream commit ecb8c2580d37dbb641451049376d80c8afaa387f ]

From ZBC-1:

 - RC BASIS = 0: The RETURNED LOGICAL BLOCK ADDRESS field indicates the
   highest LBA of a contiguous range of zones that are not sequential write
   required zones starting with the first zone.

 - RC BASIS = 1: The RETURNED LOGICAL BLOCK ADDRESS field indicates the LBA
   of the last logical block on the logical unit.

The current scsi_debug READ CAPACITY response does not comply with the
above if there are one or more sequential write required zones. SCSI
initiators need a way to retrieve the largest valid LBA from SCSI
devices. Reporting the largest valid LBA if there are one or more
sequential zones requires to set the RC BASIS field in the READ CAPACITY
response to one. Hence this patch.

cdbba6a4de scsi: ibmvfc: Avoid path failures during live migration
[ Upstream commit 62fa3ce05d5d73c5eccc40b2db493f55fecfc446 ]

Fix an issue reported when performing a live migration when multipath is
configured with a short fast fail timeout of 5 seconds and also to have
no_path_retry set to fail. In this scenario, all paths would go into the
devloss state while the ibmvfc driver went through discovery to log back
in. On a loaded system, the discovery might take longer than 5 seconds,
which was resulting in all paths being marked failed, which then resulted
in a read only filesystem.

This patch changes the migration code in ibmvfc to avoid deleting rports at
all in this scenario, so we avoid losing all paths.

5e38740ae5 Revert "net: macsec: report real_dev features when HW offloading is enabled"
[ Upstream commit 8bcd560ae8784da57c610d857118c5d6576b1a8f ]

This reverts commit c850240b6c4132574a00f2da439277ab94265b66.

That commit tried to improve the performance of macsec offload by
taking advantage of some of the NIC's features, but in doing so, broke
macsec offload when the lower device supports both macsec and ipsec
offload, as the ipsec offload feature flags (mainly NETIF_F_HW_ESP)
were copied from the real device. Since the macsec device doesn't
provide xdo_* ops, the XFRM core rejects the registration of the new
macsec device in xfrm_api_check.

Example perf trace when running
  ip link add link eni1np1 type macsec port 4 offload mac

    ip   737 [003]   795.477676: probe:xfrm_dev_event__REGISTER      name="macsec0" features=0x1c000080014869
              xfrm_dev_event+0x3a
              notifier_call_chain+0x47
              register_netdevice+0x846
              macsec_newlink+0x25a

    ip   737 [003]   795.477687:   probe:xfrm_dev_event__return      ret=0x8002 (NOTIFY_BAD)
             notifier_call_chain+0x47
             register_netdevice+0x846
             macsec_newlink+0x25a

dev->features includes NETIF_F_HW_ESP (0x04000000000000), so
xfrm_api_check returns NOTIFY_BAD because we don't have
dev->xfrmdev_ops on the macsec device.

We could probably propagate GSO and a few other features from the
lower device, similar to macvlan. This will be done in a future patch.

8395e3f98c spi: stm32: fix stm32_spi_prepare_mbr() that halves spi clk for every run
[ Upstream commit 62aa1a344b0904549f6de7af958e8a1136fd5228 ]

When this driver is used with a driver that uses preallocated spi_transfer
structs. The speed_hz is halved by every run. This results in:

spi_stm32 44004000.spi: SPI transfer setup failed
ads7846 spi0.0: SPI transfer failed: -22

Example when running with DIV_ROUND_UP():
- First run; speed_hz = 1000000, spi->clk_rate 125000000
  div 125 -> mbrdiv = 7, cur_speed = 976562
- Second run; speed_hz = 976562
  div 128,00007 (roundup to 129) -> mbrdiv = 8, cur_speed = 488281
- Third run; speed_hz = 488281
  div 256,000131072067109 (roundup to 257) and then -EINVAL is returned.

Use DIV_ROUND_CLOSEST to allow to round down and allow us to keep the
set speed.

[ Upstream commit 3a89b6dec9920026eaa90fe8457f4348d3388a98 ]

The 2.7.0 series of QCN9074's firmware requests 5 segments
of memory instead of 3 (as in the 2.5.0 series).

The first segment (11M) is too large to be kalloc'd in one
go on x86 and requires piecemeal 1MB allocations, as was
the case with the prior public firmware (2.5.0, 15M).

Since f6f92968e1e5, ath11k will break the memory requests,
but only if there were fewer than 3 segments requested by
the firmware. It seems that 5 segments works fine and
allows QCN9074 to boot on x86 with firmware 2.7.0, so
change things accordingly.

[ Upstream commit 69188df5f6e4cecc6b76b958979ba363cd5240e8 ]

Fixes a warning that occurs when rc table support is enabled
(IEEE80211_HW_SUPPORTS_RC_TABLE) in mac80211_hwsim and the PS mode
is changed via the exported debugfs attribute.

When the PS mode is changed, a packet is broadcasted via
hwsim_send_nullfunc by creating and transmitting a plain skb with only
header initialized. The ieee80211 rate array in the control buffer is
zero-initialized. When ratetbl support is enabled, ieee80211_get_tx_rates
is called for the skb with sta parameter set to NULL and thus no
ratetbl can be used. The final rate array then looks like
[-1,0; 0,0; 0,0; 0,0] which causes the warning in ieee80211_get_tx_rate.

The issue is fixed by setting the count of the first rate with idx '0'
to 1 and hence ieee80211_get_tx_rates won't overwrite it with idx '-1'.

d276fb4a7e binder: validate alloc->mm in ->mmap() handler
[ Upstream commit 3ce00bb7e91cf57d723905371507af57182c37ef ]

Since commit 1da52815d5f1 ("binder: fix alloc->vma_vm_mm null-ptr
dereference") binder caches a pointer to the current->mm during open().
This fixes a null-ptr dereference reported by syzkaller. Unfortunately,
it also opens the door for a process to update its mm after the open(),
(e.g. via execve) making the cached alloc->mm pointer invalid.

Things get worse when the process continues to mmap() a vma. From this
point forward, binder will attempt to find this vma using an obsolete
alloc->mm reference. Such as in binder_update_page_range(), where the
wrong vma is obtained via vma_lookup(), yet binder proceeds to happily
insert new pages into it.

To avoid this issue fail the ->mmap() callback if we detect a mismatch
between the vma->vm_mm and the original alloc->mm pointer. This prevents
alloc->vm_addr from getting set, so that any subsequent vma_lookup()
calls fail as expected.

8bef55d793 ceph: do not update snapshot context when there is no new snapshot
[ Upstream commit 2e586641c950e7f3e7e008404bd783a466b9b590 ]

We will only track the uppest parent snapshot realm from which we
need to rebuild the snapshot contexts _downward_ in hierarchy. For
all the others having no new snapshot we will do nothing.

This fix will avoid calling ceph_queue_cap_snap() on some inodes
inappropriately. For example, with the code in mainline, suppose there
are 2 directory hierarchies (with 6 directories total), like this:

/dir_X1/dir_X2/dir_X3/
/dir_Y1/dir_Y2/dir_Y3/

Firstly, make a snapshot under /dir_X1/dir_X2/.snap/snap_X2, then make a
root snapshot under /.snap/root_snap. Every time we make snapshots under
/dir_Y1/..., the kclient will always try to rebuild the snap context for
snap_X2 realm and finally will always try to queue cap snaps for dir_Y2
and dir_Y3, which makes no sense.

That's because the snap_X2's seq is 2 and root_snap's seq is 3. So when
creating a new snapshot under /dir_Y1/... the new seq will be 4, and
the mds will send the kclient a snapshot backtrace in _downward_
order: seqs 4, 3.

When ceph_update_snap_trace() is called, it will always rebuild the from
the last realm, that's the root_snap. So later when rebuilding the snap
context, the current logic will always cause it to rebuild the snap_X2
realm and then try to queue cap snaps for all the inodes related in that
realm, even though it's not necessary.

This is accompanied by a lot of these sorts of dout messages:

    "ceph:  queue_cap_snap 00000000a42b796b nothing dirty|writing"

Fix the logic to avoid this situation.

Also, the 'invalidate' word is not precise here. In actuality, it will
cause a rebuild of the existing snapshot contexts or just build
non-existent ones. Rename it to 'rebuild_snapcs'.

af03ce894c nvme: add a bogus subsystem NQN quirk for Micron MTFDKBA2T0TFH
[ Upstream commit 41f38043f884c66af4114a7109cf540d6222f450 ]

The Micron MTFDKBA2T0TFH device reports the same subsysem NQN for
all devices.  Add a quick to ignore it.

c6803faa6a drm/display: Don't assume dual mode adaptors support i2c sub-addressing
[ Upstream commit 5954acbacbd1946b96ce8ee799d309cb0cd3cb9d ]

Current dual mode adaptor ("DP++") detection code assumes that all
adaptors support i2c sub-addressing for read operations from the
DP-HDMI adaptor ID buffer.  It has been observed that multiple
adaptors do not in fact support this, and always return data starting
at register 0.  On affected adaptors, the code fails to read the proper
registers that would identify the device as a type 2 adaptor, and
handles those as type 1, limiting the TMDS clock to 165MHz, even if
the according register would announce a higher TMDS clock.
Fix this by always reading the ID buffer starting from offset 0, and
discarding any bytes before the actual offset of interest.

We tried finding authoritative documentation on whether or not this is
allowed behaviour, but since all the official VESA docs are paywalled,
the best we could come up with was the spec sheet for Texas Instruments'
SNx5DP149 chip family.[1]  It explicitly mentions that sub-addressing is
supported for register writes, but *not* for reads (See NOTE in
section 8.5.3).  Unless TI openly decided to violate the VESA spec, one
could take that as a hint that sub-addressing is in fact not mandated
by VESA.
The other two adaptors affected used the PS8409(A) and the LT8611,
according to the data returned from their ID buffers.

d2284fe43c ata: libata-core: do not issue non-internal commands once EH is pending
[ Upstream commit e20e81a24a4d58744a29715aac2f795cd1651955 ]

While the ATA specification states that a device should return command
aborted for all commands queued after the device has entered error state,
since ATA only keeps the sense data for the latest command (in non-NCQ
case), we really don't want to send block layer commands to the device
after it has entered error state. (Only ATA EH commands should be sent,
to read the sense data etc.)

Currently, scsi_queue_rq() will check if scsi_host_in_recovery()
(state is SHOST_RECOVERY), and if so, it will _not_ issue a command via:
scsi_dispatch_cmd() -> host->hostt->queuecommand() (ata_scsi_queuecmd())
-> __ata_scsi_queuecmd() -> ata_scsi_translate() -> ata_qc_issue()

Before commit e494f6a72839 ("[SCSI] improved eh timeout handler"),
when receiving a TFES error IRQ, the call chain looked like this:
ahci_error_intr() -> ata_port_abort() -> ata_do_link_abort() ->
ata_qc_complete() -> ata_qc_schedule_eh() -> blk_abort_request() ->
blk_rq_timed_out() -> q->rq_timed_out_fn() (scsi_times_out()) ->
scsi_eh_scmd_add() -> scsi_host_set_state(shost, SHOST_RECOVERY)

Which meant that as soon as an error IRQ was serviced, SHOST_RECOVERY
would be set.

However, after commit e494f6a72839 ("[SCSI] improved eh timeout handler"),
scsi_times_out() will instead call scsi_abort_command() which will queue
delayed work, and the worker function scmd_eh_abort_handler() will call
scsi_eh_scmd_add(), which calls scsi_host_set_state(shost, SHOST_RECOVERY).

So now, after the TFES error IRQ has been serviced, we need to wait for
the SCSI workqueue to run its work before SHOST_RECOVERY gets set.

It is worth noting that, even before commit e494f6a72839 ("[SCSI] improved
eh timeout handler"), we could receive an error IRQ from the time when
scsi_queue_rq() checks scsi_host_in_recovery(), to the time when
ata_scsi_queuecmd() is actually called.

In order to handle both the delayed setting of SHOST_RECOVERY and the
window where we can receive an error IRQ, add a check against
ATA_PFLAG_EH_PENDING (which gets set when servicing the error IRQ),
inside ata_scsi_queuecmd() itself, while holding the ap->lock.
(Since the ap->lock is held while servicing IRQs.)

[ Upstream commit 84eac327af543f03172085d5ef9f98ea25a51191 ]

This patch cleans up the code of __ata_scsi_queuecmd(). Since each
branch of the "if" condition check that scmd->cmd_len is not zero, move
this check out of the "if" to simplify the conditions being checked in
the "else" branch.

While at it, avoid the if-else-if-else structure using if-else if
structure and remove the redundant rc local variable.

This patch does not change the function logic.

81d583baa5 cifs: support nested dfs links over reconnect
[ Upstream commit c88f7dcd6d6429197fc2fd87b54a894ffcd48e8e ]

Mounting a dfs link that has nested links was already supported at
mount(2), so make it work over reconnect as well.

Make the following case work:

* mount //root/dfs/link /mnt -o ...
  - final share: /server/share

* in server settings
  - change target folder of /root/dfs/link3 to /server/share2
  - change target folder of /root/dfs/link2 to /root/dfs/link3
  - change target folder of /root/dfs/link to /root/dfs/link2

* mount -o remount,... /mnt
 - refresh all dfs referrals
 - mark current connection for failover
 - cifs_reconnect() reconnects to root server
 - tree_connect()
   * checks that /root/dfs/link2 is a link, then chase it
   * checks that root/dfs/link3 is a link, then chase it
   * finally tree connect to /server/share2

If the mounted share is no longer accessible and a reconnect had been
triggered, the client will retry it from both last referral
path (/root/dfs/link3) and original referral path (/root/dfs/link).

Any new referral paths found while chasing dfs links over reconnect,
it will be updated to TCP_Server_Info::leaf_fullpath, accordingly.

and in sctp_sched_fcfs_dequeue() it dequeued a chunk from stream
out_curr outq while this outq was empty.

Normally stream->out_curr must be set to NULL once all frag chunks of
current msg are dequeued, as we can see in sctp_sched_dequeue_done().
However, in sctp_prsctp_prune_unsent() as it is not a proper dequeue,
sctp_sched_dequeue_done() is not called to do this.

This patch is to fix it by simply setting out_curr to NULL when the
last frag chunk of current msg is dequeued from out_curr stream in
sctp_prsctp_prune_unsent().

lpuart_global_reset() shouldn't break the on-going transmit engine, need
to recover the on-going data transfer after reset.

This can help earlycon here, since commit 60f361722ad2 ("serial:
fsl_lpuart: Reset prior to registration") moved lpuart_global_reset()
before uart_add_one_port(), earlycon is writing during global reset,
as global reset will disable the TX and clear the baud rate register,
which caused the earlycon cannot work any more after reset, needs to
restore the baud rate and re-enable the transmitter to recover the
earlycon write.

Also move the lpuart_global_reset() down, then we can reuse the
lpuart32_tx_empty() without declaration.
