Kirill Tkhai says: ==================== net_rwsem fixes there is wext_netdev_notifier_call()->wireless_nlevent_flush() netdevice notifier, which takes net_rwsem, so we can't take net_rwsem in {,un}register_netdevice_notifier(). Since {,un}register_netdevice_notifier() is executed under pernet_ops_rwsem, net_namespace_list can't change, while we holding it, so there is no need net_rwsem in these functions [1/2]. The same is in [2/2]. We make callers of __rtnl_link_unregister() take pernet_ops_rwsem, and close the race with setup_net() and cleanup_net(), so __rtnl_link_unregister() does not need it. This also fixes the problem of that __rtnl_link_unregister() does not see initializing and exiting nets. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

This function calls call_netdevice_notifier(), which also may take net_rwsem. So, we can't use net_rwsem here. This patch makes callers of this functions take pernet_ops_rwsem, like register_netdevice_notifier() does. This will protect the modifications of net_namespace_list, and allows notifiers to take it (they won't have to care about context). Since __rtnl_link_unregister() is used on module load and unload (which are not frequent operations), this looks for me better, than make all call_netdevice_notifier() always executing in "protected net_namespace_list" context. Also, this fixes the problem we had a deal in 328fbe74 "Close race between {un, }register_netdevice_notifier and ...", and guarantees __rtnl_link_unregister() does not skip exitting net.

These functions take net_rwsem, while wireless_nlevent_flush() also takes it. But down_read() can't be taken recursive, because of rw_semaphore design, which prevents it to be occupied by only readers forever. Since we take pernet_ops_rwsem in {,un}register_netdevice_notifier(), net list can't change, so these down_read()/up_read() can be removed.

There is no need for explicit calls of devm_kfree(), as the allocated memory will be freed during driver's detach. The driver core clears the driver data to NULL after device_release. Thus, it is not needed to manually clear the device driver data to NULL. So remove the unnecessary pci_set_drvdata() and devm_kfree().

The three address type structs in the user API have names that in reality reflect the specific, non-Linux environment where they were originally created. We now give them more intuitive names, in accordance with how TIPC is described in the current documentation. struct tipc_portid -> struct tipc_socket_addr struct tipc_name -> struct tipc_service_addr struct tipc_name_seq -> struct tipc_service_range To avoid confusion, we also update some commmets and macro names to match the new terminology. For compatibility, we add macros that map all old names to the new ones. Signed-off-by: Jon Maloy <jon.maloy@ericsson.com> Signed-off-by: David S. Miller <davem@davemloft.net>

With the new RB tree structure for service ranges it becomes possible to solve an old problem; - we can now allow overlapping service ranges in the table. When inserting a new service range to the tree, we use 'lower' as primary key, and when necessary 'upper' as secondary key. Since there may now be multiple service ranges matching an indicated 'lower' value, we must also add the 'upper' value to the functions used for removing publications, so that the correct, corresponding range item can be found. These changes guarantee that a well-formed publication/withdrawal item from a peer node never will be rejected, and make it possible to eliminate the problematic backlog functionality we currently have for handling such cases.

Jon Maloy authored
The current design of the binding table has an unnecessary memory consuming and complex data structure. It aggregates the service range items into an array, which is expanded by a factor two every time it becomes too small to hold a new item. Furthermore, the arrays never shrink when the number of ranges diminishes. We now replace this array with an RB tree that is holding the range items as tree nodes, each range directly holding a list of bindings. This, along with a few name changes, improves both readability and volume of the code, as well as reducing memory consumption and hopefully improving cache hit rate.

Nikolay Aleksandrov says: ==================== net: bridge: MTU handling changes As previously discussed the recent changes break some setups and could lead to packet drops. Thus the first patch reverts the behaviour for the bridge to follow the minimum MTU but also keeps the ability to set the MTU to the maximum (out of all ports) if vlan filtering is enabled. Patch 02 is the bigger change in behaviour - we've always had trouble when configuring bridges and their MTU which is auto tuning on port events (add/del/changemtu), which means config software needs to chase it and fix it after each such event, after patch 02 we allow the user to configure any MTU (ETH_MIN/MAX limited) but once that is done the bridge stops auto tuning and relies on the user to keep the MTU correct. This should be compatible with cases that don't touch the MTU (or set it to the same value), while allowing to configure the MTU and not worry about it changing afterwards. The patches are intentionally split like this, so that if they get accepted and there are any complaints patch 02 can be reverted. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

As Roopa noted today the biggest source of problems when configuring bridge and ports is that the bridge MTU keeps changing automatically on port events (add/del/changemtu). That leads to inconsistent behaviour and network config software needs to chase the MTU and fix it on each such event. Let's improve on that situation and allow for the user to set any MTU within ETH_MIN/MAX limits, but once manually configured it is the user's responsibility to keep it correct afterwards. In case the MTU isn't manually set - the behaviour reverts to the previous and the bridge follows the minimum MTU.

Recently the bridge was changed to automatically set maximum MTU on port events (add/del/changemtu) when vlan filtering is enabled, but that actually changes behaviour in a way which breaks some setups and can lead to packet drops. In order to still allow that maximum to be set while being compatible, we add the ability for the user to tune the bridge MTU up to the maximum when vlan filtering is enabled, but that has to be done explicitly and all port events (add/del/changemtu) lead to resetting that MTU to the minimum as before.

The kernel calls ndo_set_rx_mode() callback supplying it will all necessary info, such as device state flags, multicast mac addresses list and so on. Since we have only 128 bits to communicate with PF we need to initiate several requests to PF with small/short operation each based on input data. So this commit implements following PF messages codes along with new data structures for them: NIC_MBOX_MSG_RESET_XCAST to flush all filters configured for this particular network interface (VF) NIC_MBOX_MSG_ADD_MCAST to add new MAC address to DMAC filter registers for this particular network interface (VF) NIC_MBOX_MSG_SET_XCAST to apply filtering configuration to filter control register Signed-off-by: Vadim Lomovtsev <Vadim.Lomovtsev@cavium.com> Signed-off-by: David S.

The ThunderX NIC could be partitioned to up to 128 VFs and thus represented to system. Each VF is mapped to pair BGX:LMAC, and each of VF is configured by kernel individually. Eventually the bunch of VFs could be mapped onto same pair BGX:LMAC and thus could cause several multicast filtering configuration requests to LMAC with the same MAC addresses. This commit is to add ThunderX NIC BGX filtering manipulation routines. Signed-off-by: Vadim Lomovtsev <Vadim.Lomovtsev@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Vadim Lomovtsev authored
The ThunderX NIC has two Ethernet Interfaces (BGX) each of them could has up to four Logical MACs configured. Each of BGX has 32 filters to be configured for filtering ingress packets. The number of filters available to particular LMAC is from 8 (if we have four LMACs configured per BGX) up to 32 (in case of only one LMAC is configured per BGX). At the same time the NIC could present up to 128 VFs to OS as network interfaces, each of them kernel will configure with set of MAC addresses for filtering. So to prevent dupes in BGX filter registers from different network interfaces it is required to cache and track all filter configuration requests prior to applying them onto BGX filter registers. This commit is to update LMAC structures with control fields to allocate/releasing filters tracking list along with implementing dmac array allocate/release per LMAC.

The ThunderX NIC has set of registers which allows to configure filter policy for ingress packets. There are three possible regimes of filtering multicasts, broadcasts and unicasts: accept all, reject all and accept filter allowed only. Current implementation has enum with all of them and two generic macro for enabling filtering et all (CAM_ACCEPT) and enabling/disabling broadcast packets, which also should be corrected in order to represent register bits properly. All these values are private for driver and there is no need to ‘publish’ them via header file. This commit is to move filtering register manipulation values from header file into source with explicit assignment of exact register values to them to be used while register configuring.

Martin Blumenstingl says: ==================== Meson8m2 support for dwmac-meson8b The Meson8m2 SoC is an updated version of the Meson8 SoC. Some of the peripherals are shared with Meson8b (for example the watchdog registers and the internal temperature sensor calibration procedure). Meson8m2 also seems to include the same Gigabit MAC register layout as Meson8b. The registers in the Amlogic dwmac "glue" seem identical between Meson8b and Meson8m2. Manual testing seems to confirm this. To be extra-safe a new compatible string is added because there's no (public) documentation on the Meson8m2 SoC.

This commit has fix for RX traffic issues when we stress test the driver with continuous ifconfig up/down under very high traffic conditions. Reason for the issue is that, in existing liquidio_stop function NAPI is disabled even before actual FW/HW interface is brought down via send_rx_ctrl_cmd(lio, 0). Between time frame of NAPI disable and actual interface down in firmware, firmware continuously enqueues rx traffic to host. When interrupt happens for new packets, host irq handler fails in scheduling NAPI as the NAPI is already disabled. After "ifconfig <iface> up", Host re-enables NAPI but cannot schedule it until it receives another Rx interrupt. Host never receives Rx interrupt as it never cleared the Rx interrupt it received during interface down operation. NIC Rx interrupt gets cleared only when Host processes queue and clears the queue counts. Above anomaly leads to other issues like packet overflow in FW/HW queues, backpressure. Fix: This commit fixes this issue by disabling NAPI only after informing firmware to stop queueing packets to host via send_rx_ctrl_cmd(lio, 0). send_rx_ctrl_cmd is not visible in the patch as it is already there in the code. The DOWN command also waits for any pending packets to be processed by NAPI so that the deadlock will not occur.
