When a RST packet is processed, we send two wakeup events to interested polling users. First one by a sk->sk_error_report(sk) from tcp_reset(), followed by a sk->sk_state_change(sk) from tcp_done(). Depending on machine load and luck, poll() can either return POLLERR, or POLLIN|POLLOUT|POLLERR|POLLHUP (this happens on 99 % of the cases) This is probably fine, but we can avoid the confusion by reordering things so that we have more TCP fields updated before the first wakeup. This might even allow us to remove some barriers we added in the past. Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Soheil Hassas Yeganeh <soheil@google.com> Signed-off-by: David S.

Jiri Pirko says: ==================== mlxsw: Allow flow based forwarding in OVS This patchset does some fixes so the HW is setup correctly to do flow-based (ACL based) forwarding for OVS-enslaved port. The first patch is just trivial fix spotted on the way. Patches 2-4 take care of proper FID setup which HW needs in order to for ACL based forwarding. The 7th patch (with dependency of patch 5 and 6) takes care of proper setup of ports that are enslaved in OVS. The last patch implements new FID miss trap that is used to push packets belonging to unknown flows to kernel and userspace. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

When there is no FID set for a specific packet, the HW will drop it. However, by default these packets are useful to be delivered to CPU as it can inspect them and program HW accordingly. So add this trap. This would only ever happen when port is enslaved to an OVS master. Otherwise, packets would be dropped during VLAN / STP filtering, before FID classification.

>From now on, a port can become a slave of OVS master. All vlans are enabled, STP state is set to "forwarding".

So far, mlxsw_sp_port_vlan_set range is limited by MLXSW_REG_SPVM_REC_MAX_COUNT. In spectrum_switchdev code this is wrapped up by a helper function which actually does multiple calls to FW for bigger ranges. Move the code into mlxsw_sp_port_vlan_set and use it always. That allows caller not to care about the range. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

For forwarding using ACL action, HW needs a valid FID to be setup. It does not actually use it, so it can be any valid FID. So create a dummy FID only for this purpose.

Juergen Borleis says: ==================== net: dsa: add SMSC/Microchip LAN9303 three port ethernet switch driver The LAN9303 is a three port 10/100 ethernet switch with integrated phys for the two external ethernet ports. The third port is an RMII/MII interface to a host master network interface (e.g. fixed link). While the LAN9303 device itself supports offload packet processing, this driver does not make use of it yet. This driver just configures the device to provide two separate network interfaces (which is the default state of a DSA device). Please note: the "MDIO managed mode" driver part isn't tested yet. I have used and tested the "I2C managed mode" only. Changes in v6: - fix support to use the driver as a module (core, i2c and mdio) - license info added in all parts of the driver (for module support) Changes in v5: - add missing include file to 'net/dsa/tag_lan9303.c' Changes in v4: - rebased on net-next, 'net/dsa/tag_lan9303.c' adapted to changed API Changes in v3: - 'ds_to_lan9303()' removed - special PHY reg MII_LAN911X_SPECIAL_CONTROL_STATUS mapping removed - compatible strings for I2C and MDIO are now different - MDIO-managed-mode devicetree binding added (still compile time tested only) Changes in v2: - code moved to 'drivers/net/dsa' - timeouts in completion wait loops - macros instead of various magic numbers - development code removed - devicetree property names changed - devicetree example adapted - tried to avoid to mix 'switching' and 'forwarding'... Comments are welcome. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

To define the outgoing port and to discover the incoming port a regular VLAN tag is used by the LAN9303. But its VID meaning is 'special'. This tag handler/filter depends on some hardware features which must be enabled in the device to provide and make use of this special VLAN tag to control the destination and the source of an ethernet packet.

The DMA API debugging (when enabled) causes: WARNING: CPU: 0 PID: 1445 at lib/dma-debug.c:519 add_dma_entry+0xe0/0x12c DMA-API: exceeded 7 overlapping mappings of cacheline 0x01b2974d to be printed after repeated initialization of the Ether device, e.g. suspend/resume or 'ifconfig' up/down. This is because DMA buffers mapped using dma_map_single() in sh_eth_ring_format() and sh_eth_start_xmit() are never unmapped. Resolve this problem by unmapping the buffers when freeing the descriptor rings; in order to do it right, we'd have to add an extra parameter to sh_eth_txfree() (we rename this function to sh_eth_tx_free(), while at it).

CONFIG_PROVE_LOCKING_SMALL shrinks the memory usage of lockdep so the kernel text, data, and bss fit in the required 32MB limit, but this option is not set for every config that enables lockdep. A 4.10 kernel fails to boot with the console output Kernel: Using 8 locked TLB entries for main kernel image. hypervisor_tlb_lock[2000000:0:8000000071c007c3:1]: errors with f Program terminated with these config options CONFIG_LOCKDEP=y CONFIG_LOCK_STAT=y CONFIG_PROVE_LOCKING=n To fix, rename CONFIG_PROVE_LOCKING_SMALL to CONFIG_LOCKDEP_SMALL, and enable this option with CONFIG_LOCKDEP=y so we get the reduced memory usage every time lockdep is turned on. Tested that CONFIG_LOCKDEP_SMALL is set to 'y' if and only if CONFIG_LOCKDEP is set to 'y'. When other lockdep-related config options that select CONFIG_LOCKDEP are enabled (e.g. CONFIG_LOCK_STAT or CONFIG_PROVE_LOCKING), verified that CONFIG_LOCKDEP_SMALL is also enabled.

We disable VxLAN offload when more than 1 UDP port is added to the driver, since Skyhawk doesn't support offload with multiple ports. The existing driver design expects the user to delete all port configurations and create a configuration with a single UDP port for VxLAN offload to be re-enabled. Remove this restriction by tracking the ports added and re-enabling offload when ports get deleted and only 1 port is left.

We need to ensure the loads from the descriptor are done after the MMIO store clearing the interrupts has completed, otherwise we might still miss work.
