Sven-Haegar reported looping on fib dumps when 255.255.255.255 route has
been added to a table. The looping is caused by the key rolling over from
FFFFFFFF to 0. When dumping a specific table only, we need a means to detect
when the table dump is done. The key and count saved to cb args are both 0
only at the start of the table dump. If key is 0 and count > 0, then we are
in the rollover case. Detect and return to avoid looping.
This only affects dumps of a specific table; for dumps of all tables
(the case prior to the change in the Fixes tag) inet_dump_fib moved
the entry counter to the next table and reset the cb args used by
fib_table_dump and fn_trie_dump_leaf, so the rollover ffffffff back
to 0 did not cause looping with the dumps.

net: stmmac: Filtering fixes
Two single fixes for the L3 and L4 filtering in stmmac.
1) Updates the internal status of RSS when disabling it in order to keep
internal driver status consistent.
2) Do not lets user add a filter if RSS is enabled because the filter will
not work correctly as RSS bypasses this mechanism.

Mallesham reports the TLS with async accelerator was broken by
commit d10523d0b3d7 ("net/tls: free the record on encryption error")

When device loses sync mid way through a record - kernel
has to re-encrypt the part of the record which the device
already decrypted to be able to decrypt and authenticate
the record in its entirety.
The re-encryption piggy backs on the decryption routine,
but obviously because the partially decrypted record can't
be authenticated crypto API returns an error which is then
ignored by tls_device_reencrypt().
Commit 5c5ec6685806 ("net/tls: add TlsDecryptError stat")
added a statistic to count decryption errors, this statistic
can't be incremented when we see the expected re-encryption
error. Move the inc to the caller.

It's possible to leak time wait and request sockets via the following
BPF pseudo code:
sk = bpf_skc_lookup_tcp(...)
if (sk)
bpf_sk_release(sk)
If sk->sk_state is TCP_NEW_SYN_RECV or TCP_TIME_WAIT the refcount taken
by bpf_skc_lookup_tcp is not undone by bpf_sk_release. This is because
sk_flags is re-used for other data in both kinds of sockets. The check
!sock_flag(sk, SOCK_RCU_FREE)
therefore returns a bogus result. Check that sk_flags is valid by calling
sk_fullsock. Skip checking SOCK_RCU_FREE if we already know that sk is
not a full socket.

Doing an add/remove/add on a SCSI device in an enclosure leads to an oops
caused by poisoned values in the enclosure device list pointers. The
reason is because we are keeping the enclosure device across the enclosed
device add/remove/add but the current code is doing a
device_add/device_del/device_add on it. This is the wrong thing to do in
sysfs, so fix it by not doing a device_del on the enclosure device simply
because of a hot remove of the drive in the slot.

Intel Wired LAN Driver Updates 2020-01-09

drivers.
Brett fixes the validation of the virtchnl queue select bitmaps by
comparing the bitmaps against BIT(I40E_MAX_VF_QUEUES).
Radoslaw removes the limitation of only 10 filter entries for a VF and
allows use of all free RAR entries for the forwarding database, if
needed.
Cambda Zhu fixes the calculation of queue when restoring flow director
filters after resetting the adapter for ixgbe.
Manfred Rudigier fixes the SGMIISFP module discovery for 100FX/LX
modules for igb.
Stefan Assmann fixes iavf where during a VF reset event, MAC filters
were not altered, which could lead to a stale filter when an
administratively set MAC address is forced by the PF.
Adam adds the missing code to set the PHY access flag on X722 devices,
which supports accessing PHY registers with the admin queue command.

This patch fixes 2 issues in x25_connect():
1. It makes absolutely no sense to reset the neighbour and the
connection state after a (successful) nonblocking call of x25_connect.
This prevents any connection from being established, since the response
(call accept) cannot be processed.
2. Any further calls to x25_connect() while a call is pending should
simply return, instead of creating new Call Request (on different
logical channels).
This patch should also fix the "KASAN: null-ptr-deref Write in
x25_connect" and "BUG: unable to handle kernel NULL pointer dereference
in x25_connect" bugs reported by syzbot.

In current driver, locks can be taken as follows:
- Register access: take a lock on regmap config and then on clock.
- Master clock provider: take a lock on clock and then on regmap config.
This can lead to the circular locking summarized below.
Remove peripheral clock management through regmap framework, and manage
peripheral clock in driver instead. On register access, lock on clock
is taken first, which allows to avoid possible locking issue.

Micron flashes do not support 16 bit writes on the Status Register.
According to micron datasheets, when using the Write Status Register
(01h) command, the chip select should be driven LOW and held LOW until
the eighth bit of the last data byte has been latched in, after which
it must be driven HIGH. If CS is not driven HIGH, the command is not
executed, flag status register error bits are not set, and the write enable
latch remains set to 1. This fixes the lock operations on micron flashes.

We are currently using nand_soft_waitrdy to poll the status of the NAND
flash. FMC2 enables the wait feature bit (this feature is mandatory for
the sequencer mode). By enabling this feature, we can't poll the status
of the NAND flash, the read status command is stucked in FMC2 pipeline
until R/B# signal is high, and locks the CPU bus.
To avoid to lock the CPU bus, we poll FMC2 ISR register. This register
reports the status of the R/B# signal.

Currently MAC filters are not altered during a VF reset event. This may
lead to a stale filter when an administratively set MAC is forced by the
PF.
For an administratively set MAC the PF driver deletes the VFs filters,
overwrites the VFs MAC address and triggers a VF reset. However
the VF driver itself is not aware of the filter removal, which is what
the VF reset is for.
The VF reset queues all filters present in the VF driver to be re-added
to the PF filter list (including the filter for the now stale VF MAC
address) and triggers a VIRTCHNL_OP_GET_VF_RESOURCES event, which
provides the new MAC address to the VF.
When this happens i40e will complain and reject the stale MAC filter,
at least in the untrusted VF case.
i40e 0000:08:00.0: Setting MAC 3c:fa:fa:fa:fa:01 on VF 0
iavf 0000:08:02.0: Reset warning received from the PF
iavf 0000:08:02.0: Scheduling reset task
i40e 0000:08:00.0: Bring down and up the VF interface to make this change effective.
i40e 0000:08:00.0: VF attempting to override administratively set MAC address, bring down and up the VF interface to resume normal operation
i40e 0000:08:00.0: VF 0 failed opcode 10, retval: -1
iavf 0000:08:02.0: Failed to add MAC filter, error IAVF_ERR_NVM
To avoid re-adding the stale MAC filter it needs to be removed from the
VF driver's filter list before queuing the existing filters. Then during
the VIRTCHNL_OP_GET_VF_RESOURCES event the correct filter needs to be
added again, at which point the MAC address has been updated.
As a bonus this change makes bringing the VF down and up again
superfluous for the administratively set MAC case.

Changing the link mode should also be done for 100BaseFX SGMII modules,
otherwise they just don't work when the default link mode in CTRL_EXT
coming from the EEPROM is SERDES.
Additionally 100Base-LX SGMII SFP modules are also supported now, which
was not the case before.
Tested with an i210 using Flexoptix S.1303.2M.G 100FX and
S.1303.10.G 100LX SGMII SFP modules.

This patch fixes the calculation of queue when we restore flow director
filters after resetting adapter. In ixgbe_fdir_filter_restore(), filter's
vf may be zero which makes the queue outside of the rx_ring array.
The calculation is changed to the same as ixgbe_add_ethtool_fdir_entry().

Currently, though the FDB entry is added to VF, it does not appear in

Currently in i40e_vc_disable_queues_msg() we are incorrectly
validating the virtchnl queue select bitmaps. The
virtchnl_queue_select rx_queues and tx_queue bitmap is being
compared against ICE_MAX_VF_QUEUES, but the problem is that
these bitmaps can have a value greater than I40E_MAX_VF_QUEUES.
Fix this by comparing the bitmaps against BIT(I40E_MAX_VF_QUEUES).
Also, add the function i40e_vc_validate_vqs_bitmaps() that checks to see
if both virtchnl_queue_select bitmaps are empty along with checking that
the bitmaps only have valid bits set. This function can then be used in
both the queue enable and disable flows.

This patch moves the reset invocation of an ap device when
fresh detected from the ap bus to the probe() function of
the driver responsible for this device.
The virtualisation of ap devices makes it necessary to
remove unconditioned resets on fresh appearing apqn devices.
It may be that such a device is already enabled for guest
usage. So there may be a race condition between host ap bus
and guest ap bus doing the reset. This patch moves the
reset from the ap bus to the zcrypt drivers. So if there
is no zcrypt driver bound to an ap device - for example
the ap device is bound to the vfio device driver - the
ap device is untouched passed to the vfio device driver.
