39f14c00b1 nfp: flower: fix stats id allocation
As flower rules are added, they are given a stats ID based on the number
of rules that can be supported in firmware. Only after the initial
allocation of all available IDs does the driver begin to reuse those that
have been released.

The initial allocation of IDs was modified to account for multiple memory
units on the offloaded device. However, this introduced a bug whereby the
counter that controls the IDs could be decremented before the ID was
assigned (where it is further decremented). This means that the stats ID
could be assigned as -1/0xfffffff which is out of range.

Fix this by only decrementing the main counter after the current ID has
been assigned.

59437d78f0 cxgb4/chtls: fix ULD connection failures due to wrong TID base
Currently, the hardware TID index is assumed to start from index 0.
However, with the following changeset,

commit c219399988 ("cxgb4: add support for high priority filters")

hardware TID index can start after the high priority region, which
has introduced a regression resulting in connection failures for
ULDs.

So, fix all related code to properly recalculate the TID start index
based on whether high priority filters are enabled or not.

cad46039e4 net: qlogic: Fix error paths in ql_alloc_large_buffers()
ql_alloc_large_buffers() has the usual RX buffer allocation
loop where it allocates skbs and maps them for DMA.  It also
treats failure as a fatal error.

There are (at least) three bugs in the error paths:

1. ql_free_large_buffers() assumes that the lrg_buf[] entry for the
first buffer that couldn't be allocated will have .skb == NULL.
But the qla_buf[] array is not zero-initialised.

2. ql_free_large_buffers() DMA-unmaps all skbs in lrg_buf[].  This is
incorrect for the last allocated skb, if DMA mapping failed.

3. Commit 1acb8f2a7a ("net: qlogic: Fix memory leak in
ql_alloc_large_buffers") added a direct call to dev_kfree_skb_any()
after the skb is recorded in lrg_buf[], so ql_free_large_buffers()
will double-free it.

The bugs are somewhat inter-twined, so fix them all at once:

* Clear each entry in qla_buf[] before attempting to allocate
  an skb for it.  This goes half-way to fixing bug 1.
* Set the .skb field only after the skb is DMA-mapped.  This
  fixes the rest.

daa6eb5a14 dpaa2-ptp: fix double free of the ptp_qoriq IRQ
Upon reusing the ptp_qoriq driver, the ptp_qoriq_free() function was
used on the remove path to free any allocated resources.
The ptp_qoriq IRQ is among these resources that are freed in
ptp_qoriq_free() even though it is also a managed one (allocated using
devm_request_threaded_irq).

Drop the resource managed version of requesting the IRQ in order to not
trigger a double free of the interrupt as below:

ef8e0b808b net: mvpp2: update mvpp2 validate() implementation
Fix up the mvpp2 validate implementation to adopt the same behaviour as
mvneta:
- only allow the link modes that the specified PHY interface mode
  supports with the exception of 1000base-X and 2500base-X.
- use the basex helper to deal with SFP modules that can be switched
  between 1000base-X vs 2500base-X.

This gives consistent behaviour between mvneta and mvpp2.

In all cases reason was that r8169.ko was in initramfs, but realtek.ko
not. Manually adding realtek.ko to initramfs fixed the issues.
Root cause seems to be that tools like dracut and genkernel don't

f3f2364ea1 net: marvell: mvpp2: phylink requires the link interrupt
phylink requires the MAC to report when its link status changes when
operating in inband modes.  Failure to report link status changes
means that phylink has no idea when the link events happen, which
results in either the network interface's carrier remaining up or
remaining permanently down.

For example, with a fiber module, if the interface is brought up and
link is initially established, taking the link down at the far end
will cut the optical power.  The SFP module's LOS asserts, we
deactivate the link, and the network interface reports no carrier.

When the far end is brought back up, the SFP module's LOS deasserts,
but the MAC may be slower to establish link.  If this happens (which
in my tests is a certainty) then phylink never hears that the MAC
has established link with the far end, and the network interface is
stuck reporting no carrier.  This means the interface is
non-functional.

Avoiding the link interrupt when we have phylink is basically not
an option, so remove the !port->phylink from the test.

1d1997db87 Revert "nfp: abm: fix memory leak in nfp_abm_u32_knode_replace"
This reverts commit 78beef629f ("nfp: abm: fix memory leak in
nfp_abm_u32_knode_replace").

The quoted commit does not fix anything and resulted in a bogus
CVE-2019-19076.

If match is NULL then it is known there is no matching entry in
list, hence, calling nfp_abm_u32_knode_delete() is pointless.

6adc4601c2 bnxt: apply computed clamp value for coalece parameter
After executing "ethtool -C eth0 rx-usecs-irq 0", the box becomes
unresponsive, likely due to interrupt livelock.  It appears that
a minimum clamp value for the irq timer is computed, but is never
applied.

Fix by applying the corrected clamp value.

24dee0c747 net: ena: fix napi handler misbehavior when the napi budget is zero
In netpoll the napi handler could be called with budget equal to zero.
Current ENA napi handler doesn't take that into consideration.

The napi handler handles Rx packets in a do-while loop.
Currently, the budget check happens only after decrementing the
budget, therefore the napi handler, in rare cases, could run over
MAX_INT packets.

In addition to that, this moves all budget related variables to int
calculation and stop mixing u32 to avoid ambiguity

VFs are also involved in firmware reset and recovery.  Modify

Fix the logic to properly check the fw capabilities and create the

the reporters unconditionally as long as bp->fw_health is valid, and
that's not correct.

Call bnxt_dl_fw_reporters_create() directly from the init and reset
code path instead of from bnxt_dl_register().  This allows the
reporters to be adjusted when capabilities change.  The same
applies to bnxt_dl_fw_reporters_destroy().

used to map the buffer.

Hence, fix an issue by passing correct buffer length in CPDMA descriptor.

In case the driver vetoes the addition of an IPv6 multipath route, the
IPv6 stack will emit delete notifications for the sibling routes that
were already added to the FIB trie. Since these siblings are not present
in hardware, a warning will be generated.

Have the driver ignore notifications for routes it does not have.

04aa1bc42e lpc_eth: kernel BUG on remove
We may have found a bug in the nxp/lpc_eth.c driver. The function
platform_set_drvdata() is called twice, the second time it is called,
in lpc_mii_init(), it overwrites the struct net_device which should be
at pdev->dev->driver_data with pldat->mii_bus. When trying to remove
the driver, in lpc_eth_drv_remove(), platform_get_drvdata() will
return the pldat->mii_bus pointer and try to use it as a struct
net_device pointer. This causes unregister_netdev to segfault and
generate a kernel BUG. Is this reproducible?

If this register is not changed when the ST bit is set to 0, then
the DMA takes the descriptor address where it was stopped earlier.

The stmmac_tx_err() does zero indices to Tx descriptors, but does
not reset HW current Tx descriptor address. To fix inconsistency,
the base address of the Tx descriptors should be rewritten before

The EEE support has not been enabled on ENETC, but it may connect
to a PHY which supports EEE and advertises EEE by default, while
its link partner also advertises EEE. If this happens, the PHY enters
low power mode when the traffic rate is low and causes packet loss.
This patch disables EEE advertisement by default for any PHY that
ENETC connects to, to prevent the above unwanted outcome.

d1a37dedcf net: hns3: fix a use after free problem in hns3_nic_maybe_stop_tx()
Currently, hns3_nic_maybe_stop_tx() uses skb_copy() to linearize a
SKB if the BD num required by the SKB does not meet the hardware
limitation, and it linearizes the SKB by allocating a new linearized SKB
and freeing the old SKB, if hns3_nic_maybe_stop_tx() returns -EBUSY
because there are no enough space in the ring to send the linearized
skb to hardware, the sch_direct_xmit() still hold reference to old SKB
and try to retransmit the old SKB when dev_hard_start_xmit() return
TX_BUSY, which may cause use after freed problem.

This patch fixes it by using __skb_linearize() to linearize the
SKB in hns3_nic_maybe_stop_tx().

There is timing window between ring_space checking and
netif_stop_subqueue when transmiting a SKB, and the TX BD
cleaning may be executed during the time window, which may
caused TX queue not restarted problem.

This patch fixes it by rechecking the ring_space after
netif_stop_subqueue to make sure TX queue is restarted.

Also, the ring->next_to_clean is updated even when pkts is
zero, because all the TX BD cleaned may be non-SKB, so it
needs to check if TX queue need to be restarted.

c55d8b108c net/mlx5e: Fix TXQ indices to be sequential
Cited patch changed (channel index, tc) => (TXQ index) mapping to be a
static one, in order to keep indices consistent when changing number of
channels or TCs.

For 32 channels (OOB) and 8 TCs, real num of TXQs is 256.
When reducing the amount of channels to 8, the real num of TXQs will be
changed to 64.
This indices method is buggy:
- Channel #0, TC 3, the TXQ index is 96.
- Index 8 is not valid, as there is no such TXQ from driver perspective
  (As it represents channel #8, TC 0, which is not valid with the above
  configuration).

As part of driver's select queue, it calls netdev_pick_tx which returns an
index in the range of real number of TXQs. Depends on the return value,
with the examples above, driver could have returned index larger than the
real number of tx queues, or crash the kernel as it tries to read invalid
address of SQ which was not allocated.

Fix that by allocating sequential TXQ indices, and hold a new mapping
between (channel index, tc) => (real TXQ index). This mapping will be
updated as part of priv channels activation, and is used in
mlx5e_select_queue to find the selected queue index.

The existing indices mapping (channel_tc2txq) is no longer needed, as it
is used only for statistics structures and can be calculated on run time.
Delete its definintion and updates.

6c8991f415 net: ipv6_stub: use ip6_dst_lookup_flow instead of ip6_dst_lookup
ipv6_stub uses the ip6_dst_lookup function to allow other modules to
perform IPv6 lookups. However, this function skips the XFRM layer
entirely.

All users of ipv6_stub->ip6_dst_lookup use ip_route_output_flow (via the
ip_route_output_key and ip_route_output helpers) for their IPv4 lookups,
which calls xfrm_lookup_route(). This patch fixes this inconsistent
behavior by switching the stub to ip6_dst_lookup_flow, which also calls
xfrm_lookup_route().

This requires some changes in all the callers, as these two functions
take different arguments and have different return types.

Currently a switch driver deinit frees the regmaps, but the PTP clock is

937d6eefc7 Here's the main documentation changes for 5.5:
- Various kerneldoc script enhancements.
 
  - More RST conversions; those are slowing down as we run out of things to
    convert, but we're a ways from done still.
 
  - Dan's "maintainer profile entry" work landed at last.  Now we just need
    to get maintainers to fill in the profiles...
 
  - A reworking of the parallel build setup to work better with a variety of
    systems (and to not take over huge systems entirely in particular).
 
  - The MAINTAINERS file is now converted to RST during the build.
    Hopefully nobody ever tries to print this thing, or they will need to
    load a lot of paper.
 
  - A script and documentation making it easy for maintainers to add Link:
    tags at commit time.
 
 Also included is the removal of a bunch of spurious CR characters.

398fd408cc r8169: fix resume on cable plug-in
It was reported [0] that network doesn't wake up on cable plug-in with
certain chip versions. Reason is that on these chip versions the PHY
doesn't detect cable plug-in when being in power-down mode. So prevent
the PHY from powering down if WoL is enabled.

The recently updated ALE APIs cpsw_ale_del_mcast() and
cpsw_ale_del_vlan_modify() have an issue and will not delete ALE entry even
if VLAN/mcast group has no more members. Hence fix it here and delete ALE
entry if !port_mask.

The issue affected only new cpsw switchdev driver.

====================
This series extends RTNETLINK to provide IB port and node GUIDs, which
were configured for Infiniband VFs.

The functionality to set VF GUIDs already existed for a long time, and
here we are adding the missing "get" so that netlink will be symmetric and
various cloud orchestration tools will be able to manage such VFs more
naturally.

The iproute2 was extended too to present those GUIDs.

- ip link show <device>

For example:
- ip link set ib4 vf 0 node_guid 22:44:33:00:33:11:00:33
- ip link set ib4 vf 0 port_guid 10:21:33:12:00:11:22:10

Rename the mac_link_state() method to mac_pcs_get_state() to make it
clear that it should be returning the MACs PCS current state, which

MAC has been configured for. Update the documentation to explicitly
mention that this is for inband.

We drop the return value as well; most of phylink doesn't check the

0aa6608dae sfc: suppress MCDI errors from ARFS
In high connection count usage, the NIC's filter table may be filled with
 sufficiently many ARFS filters that further insertions fail.  As this
 does not represent a correctness issue, do not log the resulting MCDI
 errors.  Add a debug-level message under the (by default disabled)
 rx_status category instead; and take the opportunity to do a little extra
 expiry work.

Since there are now multiple workitems able to call __efx_filter_rfs_expire
 on a given channel, it is possible for them to race and thus pass quotas
 which, combined, exceed rfs_filter_count.  Thus, don't WARN_ON if we loop
 all the way around the table with quota left over.

8490e75cdb sfc: change ARFS expiry mechanism
The old rfs_filters_added method for determining the quota could potentially
 allow the NIC to become filled with old filters, which never get tested for
 expiry.  Instead, explicitly make expiry check work depend on the number of
 filters installed, and don't count checking slots without filters in as
 doing work.  This guarantees that each filter will be checked for expiry at
 least once every thirty seconds (assuming the channel to which it belongs is
 NAPI polling actively) regardless of fill level.

Jeff Kirsher says:

====================
This series contains updates to the ice driver only.

Bruce updates the driver to store the number of functions the device has
so that it won't have to compute it when setting safe mode capabilities.
Adds a check to adjust the reporting of capabilities for devices with
more than 4 ports, which differ for devices with less than 4 ports.

Brett adds a helper function to determine if the VF is allowed to do
VLAN operations based on the host's VF configuration.  Also adds a new
function that initializes VLAN stripping (enabled/disabled) for the VF
based on the device supported capabilities.  Adds a check if the vector
index is valid with the respect to the number of transmit and receive
queues configured when we set coalesce settings for DCB.  Adds a check
if the promisc_mask contains ICE_PROMISC_VLAN_RX or ICE_PROMISC_VLAN_TX
so that VLAN 0 promiscuous rules to be removed.  Add a helper macro for
a commonly used de-reference of a pointer to &pf->dev->pdev.

Jesse fixes an issue where if an invalid virtchnl request from the VF,
the driver would return uninitialized data to the VF from the PF stack,
so ensure the stack variable is initialized earlier.  Add helpers to the
virtchnl interface make the reporting of strings consistent and help
reduce stack space.  Implements VF statistics gathering via the kernel
ndo_get_vf_stats().

Akeem ensures we disable the state flag for each VF when its resources
are returned to the device.

Tony does additional cleanup in the driver to ensure the when we
allocate and free memory within the same function, we should not be
using devm_* variants; use regular alloc and free functions.

Henry implements code to query and set the number of channels on the
primary VSI for a PF via ethtool.

Jake cleans up needless NULL checks in ice_sched_cleanup_all().

Kevin updates the firmware API version to align with current NVM images.

v2: Added "Fixes:" tag to patch 5 commit description and added the use
    of netif_is_rxfh_configured() in patch 13 to see if RSS has been
    configured by the user, if so do not overwrite that configuration.

0ed96b46c0 cxgb4/chcr: update SGL DMA unmap for USO
The FW_ETH_TX_EO_WR used for sending UDP Segmentation Offload (USO)
requests expects the headers to be part of the descriptor and the
payload to be part of the SGL containing the DMA mapped addresses.
Hence, the DMA address in the first entry of the SGL can start after
the packet headers. Currently, unmap_sgl() tries to unmap from this
wrong offset, instead of the originally mapped DMA address.

So, use existing unmap_skb() instead, which takes originally saved DMA
addresses as input. Update all necessary Tx paths to save the original
DMA addresses, so that unmap_skb() can unmap them properly.
