Previously BMC's MAC address is calculated by simply adding 1 to the
last byte of network controller's MAC address, and it produces incorrect
result when network controller's MAC address ends with 0xFF.

The problem can be fixed by calling eth_addr_inc() function to increment
MAC address; besides, the MAC address is also validated before assigning
to BMC.

setting net.netfilter.nf_conntrack_timestamp=1 breaks xmit with fq
scheduler.  skb->tstamp might be "refreshed" using ktime_get_real(),
but fq expects CLOCK_MONOTONIC.

This patch removes all places in netfilter that check/set skb->tstamp:

1. To fix the bogus "start" time seen with conntrack timestamping for
   outgoing packets, never use skb->tstamp and always use current time.
2. In nfqueue and nflog, only use skb->tstamp for incoming packets,
   as determined by current hook (prerouting, input, forward).
3. xt_time has to use system clock as well rather than skb->tstamp.
   We could still use skb->tstamp for prerouting/input/foward, but
   I see no advantage to make this conditional.

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().

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

 - team_port_add()
   - team_port_enter()

       - __set_port_dev_addr()

I've discovered following discrepancy in the bindings/net/ethernet.txt
documentation, where it states following:

 - nvmem-cells: phandle, reference to an nvmem node for the MAC address;
 - nvmem-cell-names: string, should be "mac-address" if nvmem is to be..

which is actually misleading and confusing. There are only two ethernet
drivers in the tree, cadence/macb and davinci which supports this
properties.

This nvmem-cell* properties were introduced in commit 9217e566
("of_net: Implement of_get_nvmem_mac_address helper"), but
commit afa64a72 ("of: net: kill of_get_nvmem_mac_address()")
forget to properly clean up this parts.

properties at the appropriate places.  While at it, I've removed unused

Unlike atomic_add(), refcount_add() does not deal well
with a negative argument.  TLS fallback code reallocates
the skb and is very likely to shrink the truesize, leading to:

[  189.513254] WARNING: CPU: 5 PID: 0 at lib/refcount.c:81 refcount_add_not_zero_checked+0x15c/0x180
 Call Trace:

  tls_enc_skb+0xb93/0x13e0 [tls]

Once wmem_allocated count saturates the application can no longer
send data on the socket.  This is similar to Eric's fixes for GSO,
TCP:
commit 7ec318fe ("tcp: gso: avoid refcount_t warning from tcp_gso_segment()")
and UDP:
commit 575b65bc ("udp: avoid refcount_t saturation in __udp_gso_segment()").

Unlike the GSO case, for TLS fallback it's likely that the skb has
shrunk, so the "likely" annotation is the other way around (likely
branch being "sub").

Patch #1, from Petr, adjusts mlxsw to provide the same QoS behavior for
both Spectrum-1 and Spectrum-2. The fix is required due to a difference

solution are described in the detail in the changelog.

Patch #2 increases the time period in which the driver waits for the
firmware to signal it has finished its initialization. The issue will be
fixed in future firmware versions and the timeout will be decreased.

If link is down and autoneg is set to on/off, the status in ethtool does

The reason is when the link is down the function returns with zero

Move the checking of link state (up/down) to be performed after setting
autoneg value, in order to be sure that autoneg will change in any case.

this patch increases it again to a safer limit that will be reduced in

Both Spectrum-1 and Spectrum-2 chips are currently configured such that
pairs of TC n (which is used for UC traffic) and TC n+8 (which is used
for MC traffic) are feeding into the same subgroup. Strict
prioritization is configured between the two TCs, and by enabling
MC-aware mode on the switch, the lower-numbered (UC) TCs are favored
over the higher-numbered (MC) TCs.

On Spectrum-2 however, there is an issue in configuration of the
MC-aware mode. As a result, MC traffic is prioritized over UC traffic.
To work around the issue, configure the MC TCs with DWRR mode (while
keeping the UC TCs in strict mode).

With this patch, the multicast-unicast arbitration results in the same
behavior on both Spectrum-1 and Spectrum-2 chips.

free_user() could be called in atomic context.

This patch pushed the free operation off into a workqueue.

It looks like the new socket options only work correctly
for native execution, but in case of compat mode fall back
to the old behavior as we ignore the 'old_timeval' flag.

Rework so we treat SO_RCVTIMEO_NEW/SO_SNDTIMEO_NEW the
same way in compat and native 32-bit mode.

For some reason, tcp_grow_window() correctly tests if enough room
is present before attempting to increase tp->rcv_ssthresh,
but does not prevent it to grow past tcp_space()

This is causing hard to debug issues, like failing
the (__tcp_select_window(sk) >= tp->rcv_wnd) test
in __tcp_ack_snd_check(), causing ACK delays and possibly
slow flows.

Depending on tcp_rmem[2], MTU, skb->len/skb->truesize ratio,
we can see the problem happening on "netperf -t TCP_RR -- -r 2000,2000"
after about 60 round trips, when the active side no longer sends
immediate acks.

This bug predates git history.
