Fix it the easy way by returning the ordering of sctp_primitive_ASSOCIATE and sctp_wait_for_sndbuf to the old order, to ensure that EPIPE will not happen.

Corentin Labbe cleans up the left over FCoE files in the i40e driver. Gustavo A R Silva fixes a cut and paste error. Paweł fixes a race condition when the VF driver is loaded on a host and virsh is trying to attach it to the virtual machine and set a MAC address. Resolve the issue by adding polling in i40e_ndo_set_vf_mac() when the VF is in reset mode. Jake cleans up i40e_vlan_rx_register() since this only used in a single location, so just inline the contents of the function. Created a helper function to proper update the per-filter statistics when we delete it. Factored out the re-enabling ATR and SB rules. Fixed an issue when re-enabling ATR after the last TCPv4 filter is removed and ntuple is still active, we were not restoring the TCPv4 filter input set. Filip modifies the permission check function to ensure that it knows how many filters are being requested, which allows the check to ensure that the total number of filters in a single request does not cause us to go over the limit. Mariusz fixed an issue where the wrong calculation of partition id was being done on OCP PHY mezzanine cards, which in turn caused wake on LAN to be disabled on certain ports. ==================== Signed-off-by: NDavid S.

When we re-enable ATR we need to restore the input set for TCPv4 filters, in order for ATR to function correctly. We already do this for the normal case of re-enabling ATR when disabling ntuple support. However, when re-enabling ATR after the last TCPv4 filter is removed (but when ntuple support is still active), we did not restore the TCPv4 filter input set. This can cause problems if the TCPv4 filters from FDir had changed the input set, as ATR will no longer behave as expected. When clearing the ATR auto-disable flag, make sure we restore the TCPv4 input set to avoid this.

This patch overwrites number of ports for X722 devices with support for OCP PHY mezzanine. The old method with checking if port is disabled in the PRTGEN_CNF register cannot be used in this case. When the OCP is removed, ports were seen as disabled, which resulted in wrong calculation of partition id, that caused WoL to be disabled on certain ports.

When VF requests adding of MAC filters the checking is done against number of already present MAC filters not adding them at the same time. It makes it possible to add a bunch of filters at once possibly exceeding acceptable limit of I40E_VC_MAX_MAC_ADDR_PER_VF filters. This happens because when checking vf->num_mac, we do not check how many filters are being requested at once. Modify the check function to ensure that it knows how many filters are being requested. This allows the check to ensure that the total number of filters in a single request does not cause us to go over the limit. Additionally, move the check to within the lock to ensure that the vf->num_mac is checked while holding the lock to maintain consistency. We could have simply moved the call to i40e_vf_check_permission to within the loop, but this could cause a request to be non-atomic, and add some but not all the addresses, while reporting an error code. We want to avoid this behavior so that users are not confused about which filters have or have not been added.

We used to use the function i40e_vlan_rx_register as a way to hook into the now defunct .ndo_vlan_rx_register netdev hook. This was removed but we kept the function around because we still used it internally to control enabling or disabling of VLAN stripping. As pointed out in upstream review, VLAN stripping is only used in a single location and the previous function is quite small, just inline it into i40e_restore_vlan() rather than carrying the function separately.

This patch is to add SCTP_AUTH_FREE_KEY type for AUTHENTICATION_EVENT, as described in section 6.1.8 of RFC6458. SCTP_AUTH_FREE_KEY: This report indicates that the SCTP implementation will no longer use the key identifier specified in auth_keynumber. After deactivating a key, it would never be used again, which means it's refcnt can't be held/increased by new chunks. But there may be some chunks in out queue still using it. So only when refcnt is 1, which means no chunk in outqueue is using/holding this key either, this EVENT would be sent. When users receive this notification, they could do DEL_KEY sockopt to remove this shkey, and also tell the peer that this key won't be used in any chunk thoroughly from now on, then the peer can remove it as well safely.

With refcnt support for sh_key, chunks auth sh_keys can be decided before enqueuing it. Changing the active key later will not affect the chunks already enqueued. Furthermore, this is necessary when adding the support for authinfo for sendmsg in next patch. Note that struct sctp_chunk can't be grown due to that performance drop issue on slow cpu, so it just reuses head_skb memory for shkey in sctp_chunk.

The case in which we handle a reset from the state where the device is closed seems to be bugged for all types of reset. For most types of reset we currently exit the reset routine correctly, but don't set the state to indicate that we are back in the "closed" state. For some specific cases, we don't exit the reset routine at all and resetting will cause a closed device to be opened. This patch fixes the problem by unconditionally checking the reset_state and correctly setting the adapter state before returning.

The new variable is only available when CONFIG_SYSCTL is enabled, otherwise we get a link error: net/ipv4/ip_tunnel.o: In function `ip_tunnel_init_net': ip_tunnel.c:(.text+0x278b): undefined reference to `sysctl_fb_tunnels_only_for_init_net' net/ipv6/sit.o: In function `sit_init_net': sit.c:(.init.text+0x4c): undefined reference to `sysctl_fb_tunnels_only_for_init_net' net/ipv6/ip6_tunnel.o: In function `ip6_tnl_init_net': ip6_tunnel.c:(.init.text+0x39): undefined reference to `sysctl_fb_tunnels_only_for_init_net' This adds an extra condition, keeping the traditional behavior when CONFIG_SYSCTL is disabled.

HMA(Host Memory Access) maps a part of host memory for T6-SO memfree cards. This commit does the following: - Query FW to check if we have HMA support. If yes, the params will return HMA size configured in FW. We will dma map memory based on this size. - Also contains changes to get HMA memory information via debugfs.

Kirill Tkhai says: ==================== Converting pernet_operations (part #6) this series continues to review and to convert pernet_operations to make them possible to be executed in parallel for several net namespaces in the same time. There are sctp, tipc and rds in this series. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

These pernet_operations create and destroy sysctl table and listen socket. Also, exit method flushes global workqueue and work. Everything looks per-net safe, so we can mark them async. Signed-off-by: NKirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

TIPC looks concentrated in itself, and other pernet_operations seem not touching its entities. tipc_net_ops look pernet-divided, and they should be safe to be executed in parallel for several net the same time.

These pernet_operations create and destroy net::sctp::ctl_sock. Since pernet_operations do not send sctp packets each other, they look safe to be marked as async.

These pernet_operations have a deal with sysctl, /proc entries and statistics. Also, there are freeing of net::sctp::addr_waitq queue and net::sctp::local_addr_list in exit method. All of them look pernet-divided, and it seems these items are only interesting for sctp_defaults_ops, which are safe to be executed in parallel.
