      igc: Reinstate IGC_REMOVED logic and implement it properly · 7c1ddcee
      Lennert Buytenhek authored 
      The initially merged version of the igc driver code (via commit
146740f9, "igc: Add support for PF") contained the following
IGC_REMOVED checks in the igc_rd32/wr32() MMIO accessors:

	u32 igc_rd32(struct igc_hw *hw, u32 reg)
	{
		u8 __iomem *hw_addr = READ_ONCE(hw->hw_addr);
		u32 value = 0;

		if (IGC_REMOVED(hw_addr))
			return ~value;

		value = readl(&hw_addr[reg]);

		/* reads should not return all F's */
		if (!(~value) && (!reg || !(~readl(hw_addr))))
			hw->hw_addr = NULL;

		return value;
	}

And:

	#define wr32(reg, val) \
	do { \
		u8 __iomem *hw_addr = READ_ONCE((hw)->hw_addr); \
		if (!IGC_REMOVED(hw_addr)) \
			writel((val), &hw_addr[(reg)]); \
	} while (0)

E.g. igb has similar checks in its MMIO accessors, and has a similar
macro E1000_REMOVED, which is implemented as follows:

	#define E1000_REMOVED(h) unlikely(!(h))

These checks serve to detect and take note of an 0xffffffff MMIO read
return from the device, which can be caused by a PCIe link flap or some
other kind of PCI bus error, and to avoid performing MMIO reads and
writes from that point onwards.

However, the IGC_REMOVED macro was not originally implemented:

	#ifndef IGC_REMOVED
	#define IGC_REMOVED(a) (0)
	#endif /* IGC_REMOVED */

This led to the IGC_REMOVED logic to be removed entirely in a
subsequent commit (commit 3c215fb1, "igc: remove IGC_REMOVED
function"), with the rationale that such checks matter only for
virtualization and that igc does not support virtualization -- but a
PCIe device can become detached even without virtualization being in
use, and without proper checks, a PCIe bus error affecting an igc
adapter will lead to various NULL pointer dereferences, as the first
access after the error will set hw->hw_addr to NULL, and subsequent
accesses will blindly dereference this now-NULL pointer.

This patch reinstates the IGC_REMOVED checks in igc_rd32/wr32(), and
implements IGC_REMOVED the way it is done for igb, by checking for the
unlikely() case of hw_addr being NULL.  This change prevents the oopses
seen when a PCIe link flap occurs on an igc adapter.

      e1000e: Enable GPT clock before sending message to CSME · b49feacb
      Sasha Neftin authored 
      On corporate (CSME) ADL systems, the Ethernet Controller may stop working
("HW unit hang") after exiting from the s0ix state. The reason is that
CSME misses the message sent by the host. Enabling the dynamic GPT clock
solves this problem. This clock is cleared upon HW initialization.

      selftests/net: test nexthop without gw · cd72e61b
      Nicolas Dichtel authored 
      This test implement the scenario described in the commit
"ip: fix dflt addr selection for connected nexthop".
The test configures a nexthop object with an output device only (no gateway
address) and a route that uses this nexthop. The goal is to check if the
kernel selects a valid source address.

      ip: fix dflt addr selection for connected nexthop · 747c1430
      Nicolas Dichtel authored 
      When a nexthop is added, without a gw address, the default scope was set
to 'host'. Thus, when a source address is selected, 127.0.0.1 may be chosen
but rejected when the route is used.

When using a route without a nexthop id, the scope can be configured in the
route, thus the problem doesn't exist.

To explain more deeply: when a user creates a nexthop, it cannot specify
the scope. To create it, the function nh_create_ipv4() calls fib_check_nh()
with scope set to 0. fib_check_nh() calls fib_check_nh_nongw() wich was
setting scope to 'host'. Then, nh_create_ipv4() calls
fib_info_update_nhc_saddr() with scope set to 'host'. The src addr is
chosen before the route is inserted.

When a 'standard' route (ie without a reference to a nexthop) is added,
fib_create_info() calls fib_info_update_nhc_saddr() with the scope set by
the user. iproute2 set the scope to 'link' by default.

Here is a way to reproduce the problem:
ip netns add foo
ip -n foo link set lo up
ip netns add bar
ip -n bar link set lo up
sleep 1

ip -n foo link add name eth0 type dummy
ip -n foo link set eth0 up
ip -n foo address add 192.168.0.1/24 dev eth0

ip -n foo link add name veth0 type veth peer name veth1 netns bar
ip -n foo link set veth0 up
ip -n bar link set veth1 up

ip -n bar address add 192.168.1.1/32 dev veth1
ip -n bar route add default dev veth1

ip -n foo nexthop add id 1 dev veth0
ip -n foo route add 192.168.1.1 nhid 1

Try to get/use the route:
> $ ip -n foo route get 192.168.1.1
> RTNETLINK answers: Invalid argument
> $ ip netns exec foo ping -c1 192.168.1.1
> ping: connect: Invalid argument

Try without nexthop group (iproute2 sets scope to 'link' by dflt):
ip -n foo route del 192.168.1.1
ip -n foo route add 192.168.1.1 dev veth0

Try to get/use the route:
> $ ip -n foo route get 192.168.1.1
> 192.168.1.1 dev veth0 src 192.168.0.1 uid 0

      sfc: fix kernel panic when creating VF · ada74c55
      Íñigo Huguet authored 
      When creating VFs a kernel panic can happen when calling to
efx_ef10_try_update_nic_stats_vf.

When releasing a DMA coherent buffer, sometimes, I don't know in what
specific circumstances, it has to unmap memory with vunmap. It is
disallowed to do that in IRQ context or with BH disabled. Otherwise, we
hit this line in vunmap, causing the crash:
  BUG_ON(in_interrupt());

This patch reenables BH to release the buffer.

====================
seg6: fix skb checksum for SRH encapsulation/insertion

The Linux kernel supports Segment Routing Header (SRH)
encapsulation/insertion operations by providing the capability to: i)
encapsulate a packet in an outer IPv6 header with a specified SRH; ii)
insert a specified SRH directly after the IPv6 header of the packet.
Note that the insertion operation is also referred to as 'injection'.

The two operations are respectively supported by seg6_do_srh_encap() and
seg6_do_srh_inline(), which operate on the skb associated to the packet as
needed (e.g. adding the necessary headers and initializing them, while
taking care to recalculate the skb checksum).

seg6_do_srh_encap() and seg6_do_srh_inline() do not initialize the payload
length of the IPv6 header, which is carried out by the caller functions.
However, this approach causes the corruption of the skb checksum which
needs to be updated only after initialization of headers is completed
(thanks to Paolo Abeni for detecting this issue).

The patchset fixes the skb checksum corruption by moving the IPv6 header
payload length initialization from the callers of seg6_do_srh_encap() and
seg6_do_srh_inline() directly into these functions.

This patchset is organized as follows:
 - patch 1/3, seg6: fix skb checksum evaluation in SRH
   encapsulation/insertion;
    (* SRH encapsulation/insertion available since v4.10)

 - patch 2/3, seg6: fix skb checksum in SRv6 End.B6 and End.B6.Encaps
   behaviors;
    (* SRv6 End.B6 and End.B6.Encaps behaviors available since v4.14)

 - patch 3/3, seg6: bpf: fix skb checksum in bpf_push_seg6_encap();
    (* bpf IPv6 Segment Routing helpers available since v4.18)

      seg6: bpf: fix skb checksum in bpf_push_seg6_encap() · 4889fbd9
      Andrea Mayer authored 
      Both helper functions bpf_lwt_seg6_action() and bpf_lwt_push_encap() use
the bpf_push_seg6_encap() to encapsulate the packet in an IPv6 with Segment
Routing Header (SRH) or insert an SRH between the IPv6 header and the
payload.
To achieve this result, such helper functions rely on bpf_push_seg6_encap()
which, in turn, leverages seg6_do_srh_{encap,inline}() to perform the
required operation (i.e. encap/inline).

This patch removes the initialization of the IPv6 header payload length
from bpf_push_seg6_encap(), as it is now handled properly by
seg6_do_srh_{encap,inline}() to prevent corruption of the skb checksum.

      seg6: fix skb checksum evaluation in SRH encapsulation/insertion · df8386d1
      Andrea Mayer authored 
      Support for SRH encapsulation and insertion was introduced with
commit 6c8702c6 ("ipv6: sr: add support for SRH encapsulation and
injection with lwtunnels"), through the seg6_do_srh_encap() and
seg6_do_srh_inline() functions, respectively.
The former encapsulates the packet in an outer IPv6 header along with
the SRH, while the latter inserts the SRH between the IPv6 header and
the payload. Then, the headers are initialized/updated according to the
operating mode (i.e., encap/inline).
Finally, the skb checksum is calculated to reflect the changes applied
to the headers.

The IPv6 payload length ('payload_len') is not initialized
within seg6_do_srh_{inline,encap}() but is deferred in seg6_do_srh(), i.e.
the caller of seg6_do_srh_{inline,encap}().
However, this operation invalidates the skb checksum, since the
'payload_len' is updated only after the checksum is evaluated.

To solve this issue, the initialization of the IPv6 payload length is
moved from seg6_do_srh() directly into the seg6_do_srh_{inline,encap}()
functions and before the skb checksum update takes place.
