David Ahern be659b8d3c ipv6: Restore RTF_ADDRCONF check in rt6_qualify_for_ecmp
The RTF_ADDRCONF flag filters out routes added by RA's in determining
which routes can be appended to an existing one to create a multipath
route. Restore the flag check and add a comment to document the RA piece.

Corentin Labbe 39420fe04f dt-bindings: add an explanation for internal phy-mode
When working on the Allwinner internal PHY, the first work was to use
the "internal" mode, but some answer was made my mail on what are really
internal mean for PHY.

This patch write that in the doc.

David Ahern 4e54507ab1 ipv6: Simplify rt6_qualify_for_ecmp
After commit c7a1ce397a ("ipv6: Change addrconf_f6i_alloc to use
ip6_route_info_create"), the gateway is no longer filled in for fib6_nh
structs in a prefix route. Accordingly, the RTF_ADDRCONF flag check can
be dropped from the 'rt6_qualify_for_ecmp'.

Further, RTF_DYNAMIC is only set in rt6_info instances, so it can be
removed from the check as well.

This reduces rt6_qualify_for_ecmp and the mlxsw version to just checking
if the nexthop has a gateway which is the real indication of whether
entries can be coalesced into a multipath route.

David S. Miller f9e0d65b1f Merge branch 'mlxsw-Small-routing-improvements'
Ido Schimmel says:

====================
mlxsw: Small routing improvements

Patch #1 switches the driver to use a unique and stable ECMP/LAG seed.
This allows for consistent behavior across reboots and avoids hash
polarization at the same time.

Patch #2 relaxes the FIB rule validation in the driver to allow the
installation of rules that direct locally generated traffic (iif=lo).
This does not result in a discrepancy between both data paths because
packets received by the device would never match such rules.

Ido Schimmel 05414dd116 mlxsw: spectrum_router: Relax FIB rule validation
Currently, mlxsw does not support policy-based routing (PBR) and
therefore forbids the installation of non-default FIB rules except for
the l3mdev rule which is used for VRFs.

Relax the check to allow the installation of FIB rules that would never
match packets received by the device. Specifically, if the iif is that
of the loopback netdev. This is useful for users that need to redirect
locally generated packets based on FIB rules.

Ido Schimmel fa73989f26 mlxsw: spectrum: Use a stable ECMP/LAG seed
In order to get a consistent behavior of traffic flows across reboots /
module unload, we need to use the same ECMP/LAG seed.

Calculate the seed by hashing the base MAC of the device. This results
in a seed that is both unique (to avoid polarization) and consistent.

Jakub Kicinski 12c7686111 net/tls: don't leak IV and record seq when offload fails
When device refuses the offload in tls_set_device_offload_rx()
it calls tls_sw_free_resources_rx() to clean up software context
state.

Unfortunately, tls_sw_free_resources_rx() does not free all
the state tls_set_sw_offload() allocated - it leaks IV and
sequence number buffers.  All other code paths which lead to
tls_sw_release_resources_rx() (which tls_sw_free_resources_rx()
calls) free those right before the call.

Avoid the leak by moving freeing of iv and rec_seq into
tls_sw_release_resources_rx().

Jakub Kicinski 62ef81d563 net/tls: avoid potential deadlock in tls_set_device_offload_rx()
If device supports offload, but offload fails tls_set_device_offload_rx()
will call tls_sw_free_resources_rx() which (unhelpfully) releases
and reacquires the socket lock.

For a small fix release and reacquire the device_offload_lock.

Pablo Cascón 4ef6cbe80d nfp: add SR-IOV trusted VF support
By default VFs are not trusted. Add ndo_set_vf_trust support to toggle
a new per-VF bit. Coupled with FW with this capability allows a
trusted VF to change its MAC even after being administratively set by
the PF. Also populate the trusted field on ndo_get_vf_config. Add the
same ndo to the representors.

MAC tnl interruptions are different from other type of RAS and MSI-X
errors, because some bits, such as OVF/LR/RF will occur during link up
and down.

The drivers should clear status of all MAC tnl interruption bits but
shouldn't print any message that would mislead the users.

we record when they occurred, and users can query them by debugfs.

Eric Dumazet d7cc399e12 tcp: properly reset skb->truesize for tx recycling
tcp sendmsg() and sendpage() normally advance skb->data_len
and skb->truesize by the payload added to an skb.

But sendmsg(fd, ..., MSG_ZEROCOPY) has to account for whole pages,
even if a single byte of payload is used in the page.

This means that we can not assume skb->truesize can be adjusted
by skb->data_len. We must instead overwrite its value.

Otherwise skb->truesize is too big and can hit socket sndbuf limit,
especially if the skb is recycled multiple times :/

Hangbin Liu 925b0c841e team: fix possible recursive locking when add slaves
If we add a bond device which is already the master of the team interface,
we will hold the team->lock in team_add_slave() first and then request the
lock in team_set_mac_address() again. The functions are called like:

- team_add_slave()
 - team_port_add()
   - team_port_enter()
     - team_modeop_port_enter()
       - __set_port_dev_addr()
         - dev_set_mac_address()
           - bond_set_mac_address()
             - dev_set_mac_address()
  	       - team_set_mac_address

Although team_upper_dev_link() would check the upper devices but it is
called too late. Fix it by adding a checking before processing the slave.

Arnd Bergmann 0768e17073 net: socket: implement 64-bit timestamps
The 'timeval' and 'timespec' data structures used for socket timestamps
are going to be redefined in user space based on 64-bit time_t in future
versions of the C library to deal with the y2038 overflow problem,
which breaks the ABI definition.

Unlike many modern ioctl commands, SIOCGSTAMP and SIOCGSTAMPNS do not
use the _IOR() macro to encode the size of the transferred data, so it
remains ambiguous whether the application uses the old or new layout.

The best workaround I could find is rather ugly: we redefine the command
code based on the size of the respective data structure with a ternary
operator. This lets it get evaluated as late as possible, hopefully after
that structure is visible to the caller. We cannot use an #ifdef here,
because inux/sockios.h might have been included before any libc header
that could determine the size of time_t.

The ioctl implementation now interprets the new command codes as always
referring to the 64-bit structure on all architectures, while the old
architecture specific command code still refers to the old architecture
specific layout. The new command number is only used when they are
actually different.
