db2ca348c8 net: hns: Avoid net reset caused by pause frames storm
[ Upstream commit a57275d355 ]

There will be a large number of MAC pause frames on the net,
which caused tx timeout of net device. And then the net device
was reset to try to recover it. So that is not useful, and will
cause some other problems.

So need doubled ndev->watchdog_timeo if device watchdog occurred
until watchdog_timeo up to 40s and then try resetting to recover
it.

When collecting dfx information such as hardware registers when tx timeout.
Some registers for count were cleared when read. So need move this task
before update net state which also read the count registers.

c8e78cbcde net: hns: Free irq when exit from abnormal branch
[ Upstream commit c82bd077e1 ]

1.In "hns_nic_init_irq", if request irq fail at index i,
  the function return directly without releasing irq resources
  that already requested.

2.In "hns_nic_net_up" after "hns_nic_init_irq",
  if exceptional branch occurs, irqs that already requested
  are not release.

1b2f8d7cc1 net: hns: Fixed bug that netdev was opened twice
[ Upstream commit 5778b13b64 ]

After resetting dsaf to try to repair chip error such as ecc error,
the net device will be open if net interface is up. But at this time
if there is the users set the net device up with the command ifconfig,
the net device will be opened twice consecutively.

Function napi_enable was called when open device. And Kernel panic will
be occurred if it was called twice consecutively. Such as follow:
static inline void napi_enable(struct napi_struct *n)
{
         BUG_ON(!test_bit(NAPI_STATE_SCHED, &n->state));
         smp_mb__before_clear_bit();
         clear_bit(NAPI_STATE_SCHED, &n->state);

17eeca6e3d net: hns: Some registers use wrong address according to the datasheet.
[ Upstream commit 4ad26f117b ]

According to the hip06 datasheet:
1.Six registers use wrong address:
  RCB_COM_SF_CFG_INTMASK_RING
  RCB_COM_SF_CFG_RING_STS
  RCB_COM_SF_CFG_RING
  RCB_COM_SF_CFG_INTMASK_BD
  RCB_COM_SF_CFG_BD_RINT_STS
  DSAF_INODE_VC1_IN_PKT_NUM_0_REG
2.The offset of DSAF_INODE_VC1_IN_PKT_NUM_0_REG should be
  0x103C + 0x80 * all_chn_num
3.The offset to show the value of DSAF_INODE_IN_DATA_STP_DISC_0_REG
  is wrong, so the value of DSAF_INODE_SW_VLAN_TAG_DISC_0_REG will be
  overwrite

These registers are only used in "ethtool -d", so that did not cause ndev
to misfunction.

341b884043 net: hns: All ports can not work when insmod hns ko after rmmod.
[ Upstream commit 308c6cafde ]

There are two test cases:
1. Remove the 4 modules:hns_enet_drv/hns_dsaf/hnae/hns_mdio,
   and install them again, must use "ifconfig down/ifconfig up"
   command pair to bring port to work.

   This patch calls phy_stop function when init phy to fix this bug.

2. Remove the 2 modules:hns_enet_drv/hns_dsaf, and install them again,
   all ports can not use anymore, because of the phy devices register
   failed(phy devices already exists).

   Phy devices are registered when hns_dsaf installed, this patch
   removes them when hns_dsaf removed.

The two cases are sometimes related, fixing the second case also requires
fixing the first case, so fix them together.

2cd0c6f8d0 w90p910_ether: remove incorrect __init annotation

The get_mac_address() function is normally inline, but when it is
not, we get a warning that this configuration is broken:

WARNING: vmlinux.o(.text+0x4aff00): Section mismatch in reference from the function w90p910_ether_setup() to the function .init.text:get_mac_address()
The function w90p910_ether_setup() references
the function __init get_mac_address().
This is often because w90p910_ether_setup lacks a __init

2e21275082 mt76: fix potential NULL pointer dereference in mt76_stop_tx_queues
[ Upstream commit 7c250f4612 ]

Starting from mac80211 commit adf8ed01e4 ("mac80211: add an optional
TXQ for other PS-buffered frames") and commit 0eeb2b674f ("mac80211:
add an option for station management TXQ") a new per-sta queue has been
introduced for bufferable management frames.
sta->txq[IEEE80211_NUM_TIDS] is initialized just if the driver reports
the following hw flags:
- IEEE80211_HW_STA_MMPDU_TXQ
- IEEE80211_HW_BUFF_MMPDU_TXQ
This can produce a NULL pointer dereference in mt76_stop_tx_queues
since mt76 iterates on all available sta tx queues assuming they are
initialized by mac80211. This issue has been spotted analyzing the code
(it has not triggered any crash yet)

Vlans are not getting removed when drivers are unloaded. The recent storm
firmware versions had added safeguards against re-configuring an already
configured vlan. As a result, PF inner reload flows (e.g., mtu change)
might trigger an assertion.
This change is going to remove vlans (same as we do for MACs) when doing
a chip cleanup during unload.

27f59f342f ixgbe: Fix race when the VF driver does a reset
[ Upstream commit 96d1a73161 ]

When the VF driver does a reset, it (at least the Linux one) writes to
the VFCTRL register to issue a reset and then immediately sends a reset
message using the mailbox API. This is racy because when the PF driver
detects that the VFCTRL register reset pin has been asserted, it clears
the mailbox memory. Depending on ordering, the reset message sent by
the VF could be cleared by the PF driver. It then responds to the
cleared message with a NACK which causes the VF driver to malfunction.
Fix this by deferring clearing the mailbox memory until the reset
message is received.

62075c982b x86/mm: Fix guard hole handling
[ Upstream commit 16877a5570 ]

There is a guard hole at the beginning of the kernel address space, also
used by hypervisors. It occupies 16 PGD entries.

This reserved range is not defined explicitely, it is calculated relative
to other entities: direct mapping and user space ranges.

The calculation got broken by recent changes of the kernel memory layout:
LDT remap range is now mapped before direct mapping and makes the
calculation invalid.

The breakage leads to crash on Xen dom0 boot[1].

Define the reserved range explicitely. It's part of kernel ABI (hypervisors
expect it to be stable) and must not depend on changes in the rest of
kernel memory layout.

af03a980e8 ieee802154: ca8210: fix possible u8 overflow in ca8210_rx_done
[ Upstream commit 8e41cae64b ]

gcc warning this:

drivers/net/ieee802154/ca8210.c:730:10: warning:
 comparison is always false due to limited range of data type [-Wtype-limits]

'len' is u8 type, we get it from buf[1] adding 2, which can overflow.
This patch change the type of 'len' to unsigned int to avoid this,also fix
the gcc warning.

c5dabddc2c Input: omap-keypad - fix idle configuration to not block SoC idle states
[ Upstream commit e2ca26ec4f ]

With PM enabled, I noticed that pressing a key on the droid4 keyboard will
block deeper idle states for the SoC. Let's fix this by using IRQF_ONESHOT
and stop constantly toggling the device OMAP4_KBD_IRQENABLE register as
suggested by Dmitry Torokhov <dmitry.torokhov@gmail.com>.

From the hardware point of view, looks like we need to manage the registers
for OMAP4_KBD_IRQENABLE and OMAP4_KBD_WAKEUPENABLE together to avoid
blocking deeper SoC idle states. And with toggling of OMAP4_KBD_IRQENABLE
register now gone with IRQF_ONESHOT, also the SoC idle state problem is
gone during runtime. We still also need to clear OMAP4_KBD_WAKEUPENABLE in
omap4_keypad_close() though to pair it with omap4_keypad_open() to prevent
blocking deeper SoC idle states after rmmod omap4-keypad.

6bcf9ef86c netfilter: seqadj: re-load tcp header pointer after possible head reallocation

When adjusting sack block sequence numbers, skb_make_writable() gets
called to make sure tcp options are all in the linear area, and buffer
is not shared.

This can cause tcp header pointer to get reallocated, so we must
reaload it to avoid memory corruption.

cee05c0371 netfilter: nf_tables: fix suspicious RCU usage in nft_chain_stats_replace()
[ Upstream commit 4c05ec4738 ]

basechain->stats is rcu protected data which is updated from
nft_chain_stats_replace(). This function is executed from the commit
phase which holds the pernet nf_tables commit mutex - not the global
nfnetlink subsystem mutex.

Test commands to reproduce the problem are:
   %iptables-nft -I INPUT
   %iptables-nft -Z
   %iptables-nft -Z

This patch uses RCU calls to handle basechain->stats updates to fix a
splat that looks like:

083d552a89 xfrm: Fix NULL pointer dereference in xfrm_input when skb_dst_force clears the dst_entry.
[ Upstream commit 0152eee6fc ]

Since commit 222d7dbd25 ("net: prevent dst uses after free")
skb_dst_force() might clear the dst_entry attached to the skb.
The xfrm code doesn't expect this to happen, so we crash with
a NULL pointer dereference in this case.

Fix it by checking skb_dst(skb) for NULL after skb_dst_force()
and drop the packet in case the dst_entry was cleared. We also
move the skb_dst_force() to a codepath that is not used when
the transformation was offloaded, because in this case we
don't have a dst_entry attached to the skb.

The output and forwarding path was already fixed by
commit 9e14379378 ("xfrm: Fix NULL pointer dereference when
skb_dst_force clears the dst_entry.")

7519ffa911 checkstack.pl: fix for aarch64

There is actually a space after "sp," like this,

    ffff2000080813c8:       a9bb7bfd        stp     x29, x30, [sp, #-80]!

Right now, checkstack.pl isn't able to print anything on aarch64,
because it won't be able to match the stating objdump line of a function
due to this missing space.  Hence, it displays every stack as zero-size.

After this patch, checkpatch.pl is able to match the start of a
function's objdump, and is then able to calculate each function's stack
correctly.

When support for bonding of RoCE devices was added, there was
necessarily a link between the RoCE device and the paired netdevice that
was part of the bond.  If you remove the mlx4_en module, that paired
association is broken (the RoCE device is still present but the paired
netdevice has been released).  We need to account for this in
is_upper_ndev_bond_master_filter() and filter out those links with a
broken pairing or else we later oops in netdev_next_upper_dev_rcu().

[ Upstream commit c554206077 ]

If CS is submitted using guilty ctx, we terminate amdgpu_cs_parser_init
before locking ctx->lock, latter in amdgpu_cs_parser_fini we still are
trying to release the lock just becase parser->ctx != NULL.

54568ab2e1 powerpc/mm: Fallback to RAM if the altmap is unusable
[ Upstream commit 9ef34630a4 ]

The "altmap" is used to provide a pool of memory that is reserved for
the vmemmap backing of hot-plugged memory. This is useful when adding
large amount of ZONE_DEVICE memory to a system with a limited amount of
normal memory.

On ppc64 we use huge pages to map the vmemmap which requires the backing
storage to be contigious and aligned to the hugepage size. The altmap
implementation allows for the altmap provider to reserve a few PFNs at
the start of the range for it's own uses and when this occurs the
first chunk of the altmap is not usable for hugepage mappings. On hash
there is no sane way to fall back to a normal sized page mapping so we
fail the allocation. This results in memory hotplug failing with
ENOMEM when the new range doesn't fall into an existing vmemmap block.

This patch handles this case by falling back to using system memory
rather than failing if we cannot allocate from the altmap. This
fallback should only ever be used for the first vmemmap block so it
should not cause excess memory consumption.

aad142a61e ARM: dts: imx7d-nitrogen7: Fix the description of the Wifi clock
[ Upstream commit f15096f12a ]

According to bindings/regulator/fixed-regulator.txt the 'clocks' and
'clock-names' properties are not valid ones.

In order to turn on the Wifi clock the correct location for describing
the CLKO2 clock is via a mmc-pwrseq handle, so do it accordingly.

[ Upstream commit 1e434b7032 ]

The sw2iso count should cover ARM LDO ramp-up time,
the MAX ARM LDO ramp-up time may be up to more than
100us on some boards, this patch sets sw2iso to 0xf
(~384us) which is the reset value, and it is much
more safe to cover different boards, since we have
observed that some customer boards failed with current
setting of 0x2.

270a08ffa1 HID: ite: Add USB id match for another ITE based keyboard rfkill key quirk
[ Upstream commit 4050207485 ]

The 258a:6a88 keyboard-dock shipped with the Prowise PT301 tablet is
likely another ITE based design. The controller die is directly bonded
to the PCB with a blob of black glue on top so there are no markings and
the 258a vendor-id used is unknown anywhere. But the keyboard has the
exact same hotkeys mapped to Fn+F1 - F10 as the other ITE8595 keyboard
I have *and* it has the same quirky behavior wrt the rfkill hotkey.

Either way as said this keyboard has the same quirk for its rfkill /
airplane mode hotkey as the ITE 8595 chip, it only sends a single release
event when pressed and released, it never sends a press event.

This commit adds the 258a:6a88 USB id to the hid-ite id-table, fixing
the rfkill key not working on this keyboard.

4642a5c582 powerpc: Fix COFF zImage booting on old powermacs
[ Upstream commit 5564597d51 ]

Commit 6975a783d7 ("powerpc/boot: Allow building the zImage wrapper
as a relocatable ET_DYN", 2011-04-12) changed the procedure descriptor
at the start of crt0.S to have a hard-coded start address of 0x500000
rather than a reference to _zimage_start, presumably because having
a reference to a symbol introduced a relocation which is awkward to
handle in a position-independent executable.  Unfortunately, what is
at 0x500000 in the COFF image is not the first instruction, but the
procedure descriptor itself, that is, a word containing 0x500000,
which is not a valid instruction.  Hence, booting a COFF zImage
results in a "DEFAULT CATCH!, code=FFF00700" message from Open
Firmware.

This fixes the problem by (a) putting the procedure descriptor in the
data section and (b) adding a branch to _zimage_start as the first
instruction in the program.
