net: lpc32xx: ensure mdiodev->name is NULL terminated after MDIO_NAME_LEN truncation

strncpy() simply bails out when copying a source string whose size
exceeds the destination string size, potentially leaving the destination
string unterminated.

One possible way to address is to pass MDIO_NAME_LEN - 1 and a

difficult to maintain.

The chosen alternative is to use strlcpy(), which properly limits the
copy len in the (srclen >= size) case to "size - 1", and which is also

After the discussion here:

which resulted in this patch:
https://patchwork.kernel.org/project/netdevbpf/patch/20210704134325.24842-1-pali@kernel.org/

and many other discussions before it, notably:
https://patchwork.kernel.org/project/linux-arm-kernel/patch/1512016235-15909-1-git-send-email-Bhaskar.Upadhaya@nxp.com/

it became apparent that nobody really knows what "SGMII 2500" is.
Certainly, Freescale/NXP hardware engineers name this protocol
"SGMII 2500" in the reference manuals, but the PCS devices do not
support any "SGMII" specific features when operating at the speed of
2500 Mbps, no in-band autoneg and no speed change via symbol replication
. So that leaves a fixed speed of 2500 Mbps using a coding of 8b/10b
with a SERDES lane frequency of 3.125 GHz. In fact, "SGMII 2500 without
in-band autoneg and at a fixed speed" is indistinguishable from
"2500base-x without in-band autoneg", which is precisely what these NXP
devices support.

So it just appears that "SGMII 2500" is an unclear name with no clear
definition that stuck.

As such, in the Linux kernel, the drivers which use this SERDES protocol
use the 2500base-x phy-mode.

This patch converts U-Boot to use 2500base-x too, or at least, as much
as it can.

Note that I would have really liked to delete PHY_INTERFACE_MODE_SGMII_2500
completely, but the mvpp2 driver seems to even distinguish between SGMII
2500 and 2500base-X. Namely, it enables in-band autoneg for one but not
the other, and forces flow control for one but not the other. This goes
back to the idea that maybe 2500base-X is a fiber protocol and SGMII-2500
is an MII protocol (connects a MAC to a PHY such as Aquantia), but the
two are practically indistinguishable through everything except use case.

NXP devices can support both use cases through an identical configuration,
for example RX flow control can be unconditionally enabled in order to
support rate adaptation performed by an Aquantia PHY. At least I can
find no indication in online documents published by Cisco which would
point towards "SGMII-2500" being an actual standard with an actual
definition, so I cannot say "yes, NXP devices support it".

certain way.

For example, on the NXP LS1028A-RDB, the felix switch ports are
connected to a VSC8514 QSGMII PHY. Between the switch port PCS and the
PHY, the U-Boot drivers enable in-band auto-negotiation which makes the
copper-side negotiated speed and duplex be transmitted from the PHY to
the MAC automatically.

The PHY driver portion that does this is in vsc8514_config():

/* Enable Serdes Auto-negotiation */
phy_write(phydev, MDIO_DEVAD_NONE, PHY_EXT_PAGE_ACCESS,
  PHY_EXT_PAGE_ACCESS_EXTENDED3);
val = phy_read(phydev, MDIO_DEVAD_NONE, MIIM_VSC8514_MAC_SERDES_CON);
val = val | MIIM_VSC8574_MAC_SERDES_ANEG;
phy_write(phydev, MDIO_DEVAD_NONE, MIIM_VSC8514_MAC_SERDES_CON, val);

The point is that in-band autoneg should be turned on in both the PHY
and the MAC, or off in both the PHY and the MAC, otherwise the QSGMII
link will be broken.

And because phy_config() is currently called at .port_enable() time, the
result is that ports on which traffic has been sent in U-Boot will have
in-band autoneg enabled, and the rest won't.

It can be argued that the Linux kernel should not assume one way or
another and just reinitialize everything according to what it expects,
and that is completely fair. In fact, I've already started an attempt to
remove this dependency, although admittedly I am making slow progress at
it:
https://patchwork.kernel.org/project/netdevbpf/cover/20210212172341.3489046-1-olteanv@gmail.com/

Nonetheless, the sad reality is that NXP also has, apart from kernel
drivers, some user space networking (DPDK), and for some reason, the
expectation there is that somebody else initializes the PHYs. The kernel
can't do it because the device ownership doesn't belong to the kernel,
so what remains is for the bootloader to do it (especially since other
drivers generally call phy_config() at probe time). This is a really
weak guarantee that might break at any time, but apparently that is
enough for some.

Since initializing the ports and PHYs at probe time does not break
anything, we can just do that.

usb: xhci-pci: Move reset logic out of XHCI core

setup performed by the platform driver. And at least on the Allwinner
H6, resetting the XHCI controller also resets the PHY, which prevents
the controller from working. That means the controller must be taken out
of reset before initializing the PHY, which must be done before calling
xhci_register.

by starting the Armv8 ahead of parsing the elf and copying the correct

copy is in progress.

To prevent all these conditions, lets make sure that the elf parse and
copy operations are completed ahead of ARMv8 being released to execute.

Alexandru Gagniuc [Wed, 18 Aug 2021 22:49:02 +0000 (17:49 -0500)]
image: rsa: Move padding_algos to linker lists

We are not guaranteed to have the padding_pkcs_15_verify symbol since
commit 92c960bc1d ("lib: rsa: Remove #ifdefs from rsa.h"), and
commit 61416fe9df ("Kconfig: FIT_SIGNATURE should not select RSA_VERIFY")

The padding_algos only make sense with RSA verification, which can now
be disabled in lieu of ECDSA. In fact this will lead to build failures
because of the missing symbol mentioned earlier.

To resolve this, move the padding_algos to a linker list, with
declarations moved to rsa_verify.c. This is consistent with commit
6909edb4ce ("image: rsa: Move verification algorithm to a linker list")

One could argue that the added #ifdef USE_HOSTCC is ugly, and should
be hidden within the U_BOOT_PADDING_ALGO() macro. However, this would
be inconsistent with the "cryptos" list. This logic for was not
previously explored:

Without knowledge of the U_BOOT_PADDING_ALGO() macro, its use is
similar to something being declared. However, should #ifndef
USE_HOSTCC be part of the macro, it would not be obvious that it
behaves differently on host code and target code. Having the #ifndef
outside the macro makes this obvious.

Also, the #ifdef is not always necessary. For example ecda-verify
makes use of U_BOOT_CRYPTO_ALGO() without any accompanying #ifdefs.
The fundamental issue is a lack of separation of host and target code
in rsa_verify. Therefore, the declaration of a padding algo with the
external #ifdef is more readable and consistent.

sunxi: mmc: A20: Fix MMC optimisation

Some SoCs (as seen on A20) seem to misreport the MMC FIFO level if the
FIFO is completely full: the level size reads as zero, but the FIFO_FULL
bit is set. We won't do a single iteration of the read loop in this
case, so will be stuck forever.

Check for this situation and use a safe minimal FIFO size instead when
we hit this case.
