sctp: fix src address selection if using secondary address

This series improves the way SCTP chooses its src address so that the
choosen one will always belong to the interface being used for output.

v1->v2:
 - split out the refactoring from the fix itself
 - Doing a full reverse routing as in v1 is not necessary. Only looking
   for the interface that has the address and comparing its number is
   enough.

      sctp: fix src address selection if using secondary addresses · 0ca50d12
      由 Marcelo Ricardo Leitner 提交于 
      In short, sctp is likely to incorrectly choose src address if socket is
bound to secondary addresses. This patch fixes it by adding a new check
that checks if such src address belongs to the interface that routing
identified as output.

This is enough to avoid rp_filter drops on remote peer.

Details:

Currently, sctp will do a routing attempt without specifying the src
address and compare the returned value (preferred source) with the
addresses that the socket is bound to. When using secondary addresses,
this will not match.

Then it will try specifying each of the addresses that the socket is
bound to and re-routing, checking if that address is valid as src for
that dst. Thing is, this check alone is weak:

Even if you specify an interface:

192.168.100.193 from 192.168.122.148 dev eth1
    cache

Although this would be valid, peers using rp_filter will drop such
packets as their src doesn't match the routes for that interface.

1st test is useful to test performance of JIT implementation of BPF_LD_ABS
together with BPF_CALL instructions.
2nd test is stressing skb_vlan_push/pop logic together with skb->data access
via BPF_LD_ABS insn which checks that re-caching of skb->data is done correctly.

In order to call bpf_skb_vlan_push() from test_bpf.ko have to add

      bpf: introduce bpf_skb_vlan_push/pop() helpers · 4e10df9a
      由 Alexei Starovoitov 提交于 
      Allow eBPF programs attached to TC qdiscs call skb_vlan_push/pop via
helper functions. These functions may change skb->data/hlen which are
cached by some JITs to improve performance of ld_abs/ld_ind instructions.
Therefore JITs need to recognize bpf_skb_vlan_push/pop() calls,
re-compute header len and re-cache skb->data/hlen back into cpu registers.
Note, skb->data/hlen are not directly accessible from the programs,
so any changes to skb->data done either by these helpers or by other
TC actions are safe.

eBPF JIT supported by three architectures:
- arm64 JIT is using bpf_load_pointer() without caching, so it's ok as-is.
- x64 JIT re-caches skb->data/hlen unconditionally after vlan_push/pop calls
  (experiments showed that conditional re-caching is slower).
- s390 JIT falls back to interpreter for now when bpf_skb_vlan_push() is present
  in the program (re-caching is tbd).

These helpers allow more scalable handling of vlan from the programs.
Instead of creating thousands of vlan netdevs on top of eth0 and attaching
TC+ingress+bpf to all of them, the program can be attached to eth0 directly
and manipulate vlans as necessary.

Intel Wired LAN Driver Updates 2015-07-17

This series contains updates to igb, ixgbe, ixgbevf, i40e, bnx2x,
freescale, siena and dp83640.

Jacob provides several patches to clarify the intended way to implement
both SIOCSHWTSTAMP and ethtool's get_ts_info().  It is okay to support
the specific filters in SIOCSHWTSTAMP by upscaling them to the generic
filters.

Alex Duyck provides a igb patch to pull the time stamp from the fragment
before it gets added to the skb, to avoid a possible issue in which the
fragment can possibly be less than IGB_RX_HDR_LEN due to the time stamp
being pulled after the copybreak check.  Also provides a ixgbevf patch to
fold the ixgbevf_pull_tail() call into ixgbevf_add_rx_frag(), which gives
the advantage that the fragment does not have to be modified after it is
added to the skb.

Fan provides patches for ixgbe/ixgbevf to set the receive hash type
based on receive descriptor RSS type.

Todd provides a fix for igb where on check for link on any media other
than copper was not being detected since it was looking on the incorrect
PHY page (due to the page being used gets switched before the function
to check link gets executed).

net: bcmgenet: PHY initialization rework

This patch series reworks how we perform PHY initialization and resets in the
GENET driver. Although this contains mostly fixes, some of the changes are a
bit too intrusive to be backported to 'net' at the moment.

Some of the motivations behind these changes were to reduce the time spent in how
performing MDIO transactions, since it is better to perform then when we have
interrupts enabled. This reduces the bring-up time of GENET from ~600 msecs down
to ~8 msecs, and about the same time for suspend/resume.

Since I do not currently have a system which is not DT-aware, can you (Petri,
Jaedon) give this a try and confirm things keep working as expected?

      net: bcmgenet: Delay PHY initialization to bcmgenet_open() · 6cc8e6d4
      由 Florian Fainelli 提交于 
      We are currently doing a full PHY initialization and even starting the
pHY state machine during bcmgenet_mii_init() which is executed in the
driver's probe function. This is convenient to determine whether we can
attach to a proper PHY device but comes at the expense of spending up to
10ms per MDIO transactions (to reach the waitqueue timeout), which slows
things down.

This also creates a sitaution where we end-up attaching twice to the
PHY, which is not quite correct either.

Fix this by moving bcmgenet_mii_probe() into bcmgenet_open() and update
its error path accordingly.

Avoid printing the message "attached PHY at address 1 [...]" every time
we bring up/down the interface and remove this print since it duplicates
what the PHY driver already does for us.

      net: bcmgenet: Determine PHY type before scanning MDIO bus · c624f891
      由 Florian Fainelli 提交于 
      Our internal GPHY might be powered off before we attempt scanning the
MDIO bus and bind a driver to it. The way we are currently determining
whether a PHY is internal or not is done *after* we have successfully
matched its driver. If the PHY is powered down, it will not respond to
the MDIO bus, so we will not be able to bind a driver to it.

Our Device Tree for GENET interfaces specifies a "phy-mode" value:
"internal" which tells if this internal uses an internal PHY or not.

If of_get_phy_mode() fails to parse the 'phy-mode' property, do an
additional manual lookup, and if we find "internal" set the
corresponding internal variable accordingly.

Replace all uses of phy_is_internal() with a check against
priv->internal_phy to avoid having to rely on whether or not
priv->phydev is set correctly.
