[ Upstream commit 478689b5990deb626a0b3f1ebf165979914d6be4 ]
The recent regression report revealed that the use of WC pages for AMD
HDMI device together with AMD IOMMU leads to unexpected truncation or
noises. The issue seems triggered by the change in the kernel core
memory allocation that enables IOMMU driver to use always S/G
buffers. Meanwhile, the use of WC pages has been a workaround for the
similar issue with standard pages in the past. So, now we need to
apply the workaround conditionally, namely, only when IOMMU isn't in
place.
This patch modifies the workaround code to check the DMA ops at first
and apply the snoop-off only when needed.

iucv_sever_path() is called from process context and from bh context.
iucv->path is used as indicator whether somebody else is taking care of

small window where iucv_sock_close() will try to work with a path that has
already been severed and freed by iucv_callback_connrej() called by

Address a scenario in which XSK ZC Tx produces descriptors to XDP Tx
ring when link is either not yet fully initialized or process of
stopping the netdev has already started. To avoid this, add checks
against carrier readiness in ice_xsk_wakeup() and in ice_xmit_zc().
One could argue that bailing out early in ice_xsk_wakeup() would be
sufficient but given the fact that we produce Tx descriptors on behalf
of NAPI that is triggered for Rx traffic, the latter is also needed.
Bringing link up is an asynchronous event executed within
ice_service_task so even though interface has been brought up there is
still a time frame where link is not yet ok.
Without this patch, when AF_XDP ZC Tx is used simultaneously with stack
Tx, Tx timeouts occur after going through link flap (admin brings
interface down then up again). HW seem to be unable to transmit
descriptor to the wire after HW tail register bump which in turn causes
bit __QUEUE_STATE_STACK_XOFF to be set forever as
netdev_tx_completed_queue() sees no cleaned bytes on the input.

SO_RCVBUF is set leading to the maximum window scaling to be 25% of

and 50% of rcvbuf after
commit 697a6c8cec03 ("tcp: increase the default TCP scaling ratio").
50% tries to emulate the behavior of older kernels using
sysctl_tcp_adv_win_scale with default value.
Systems which were using a different values of sysctl_tcp_adv_win_scale
in older kernels ended up seeing reduced download speeds in certain
cases as covered in https://lists.openwall.net/netdev/2024/05/15/13
While the sysctl scheme is no longer acceptable, the value of 50% is
a bit conservative when the skb->len/skb->truesize ratio is later
determined to be ~0.66.
Applications not specifying SO_RCVBUF update the window scaling and
the receiver buffer every time data is copied to userspace. This
computation is now used for applications setting SO_RCVBUF to update
the maximum window scaling while ensuring that the receive buffer
is within the application specified limit.

waking up the system, so this attempts to check if hdev is marked as

is used since the devices programmed there can still wakeup be system.

The PHY built in to the Realtek RTL8366S switch controller was
previously supported by genphy_driver. This PHY does not implement MMD
operations. Since commit 9b01c885be36 ("net: phy: c22: migrate to
genphy_c45_write_eee_adv()"), MMD register reads have been made during
phy_probe to determine EEE support. For genphy_driver, these reads are
transformed into 802.3 annex 22D clause 45-over-clause 22
mmd_phy_indirect operations that perform MII register writes to
MII_MMD_CTRL and MII_MMD_DATA. This overwrites those two MII registers,
which on this PHY are reserved and have another function, rendering the
PHY unusable while so configured.
Proper support for this PHY is restored by providing a phy_driver that
declares MMD operations as unsupported by using the helper functions
provided for that purpose, while remaining otherwise identical to
genphy_driver.

[ Upstream commit 98ba1d931f611e8f8f519c0405fa0a1a76554bfa ]
In __bnxt_reserve_rings(), the existing code unconditionally sets the
default RSS indirection table to default if netif_is_rxfh_configured()
returns false. This used to be correct before we added RSS contexts
support. For example, if the user is changing the number of ethtool
channels, we will enter this path to reserve the new number of rings.
We will then set the RSS indirection table to default to cover the new
number of rings if netif_is_rxfh_configured() is false.
Now, with RSS contexts support, if the user has added or deleted RSS
contexts, we may now enter this path to reserve the new number of VNICs.
However, netif_is_rxfh_configured() will not return the correct state if
we are still in the middle of set_rxfh(). So the existing code may
set the indirection table of the default RSS context to default by
mistake.
Fix it to check if the reservation of the RX rings is changing. Only
check netif_is_rxfh_configured() if it is changing. RX rings will not
change in the middle of set_rxfh() and this will fix the issue.

Fix races issues in virtual crc generation by making sure the surface
the code uses for crc computation is properly ref counted.
Crc generation was trying to be too clever by allowing the surfaces
to go in and out of scope, with the hope of always having some kind
of screen present. That's not always the code, in particular during
atomic disable, so to make sure the surface, when present, is not
being actively destroyed at the same time, hold a reference to it.
