2020-06-01devlink: Add 'control' trap typeIdo Schimmel3-1/+20
This type is used for traps that trap control packets such as ARP request and IGMP query to the CPU. Do not report such packets to the kernel's drop monitor as they were not dropped by the device no encountered an exception during forwarding.

2020-06-01devlink: Add 'mirror' trap actionIdo Schimmel3-1/+7
The action is used by control traps such as IGMP query. The packet is flooded by the device, but also trapped to the CPU in order for the software bridge to mark the receiving port as a multicast router port. Such packets are marked with 'skb->offload_fwd_mark = 1' in order to prevent the software bridge from flooding them again.

2020-06-01net: octeon: mgmt: Repair filling of RX ringAlexander Sverdlin1-0/+5
The removal of mips_swiotlb_ops exposed a problem in octeon_mgmt Ethernet driver. mips_swiotlb_ops had an mb() after most of the operations and the removal of the ops had broken the receive functionality of the driver. My code inspection has shown no other places except octeon_mgmt_rx_fill_ring() where an explicit barrier would be obviously missing. The latter function however has to make sure that "ringing the bell" doesn't happen before RX ring entry is really written. The patch has been successfully tested on Octeon II.

However, there is another problem: The indirect flow_block still does not work for the new TC CT action. The problem is that the existing flow_indr_block_entry callback assumes you can look up for the flowtable from the netdevice to get the flow_block. This flow_block allows you to offload the flows via TC_SETUP_CLSFLOWER. Unfortunately, it is not possible to get the flow_block from the TC CT flowtables because they are _not_ bound to any specific netdevice. = What is the indirect flow_block infrastructure? The indirect flow_block infrastructure allows drivers to offload tc/netfilter rules that belong to software tunnel netdevices, e.g. vxlan. This indirect flow_block infrastructure relates tunnel netdevices with drivers because there is no obvious way to relate these two things from the control plane. = How does the indirect flow_block work before this patchset? Front-ends register the indirect block callback through flow_indr_add_block_cb() if they support for offloading tunnel netdevices. == Setting up an indirect block 1) Drivers track tunnel netdevices via NETDEV_{REGISTER,UNREGISTER} events. If there is a new tunnel netdevice that the driver can offload, then the driver invokes __flow_indr_block_cb_register() with the new tunnel netdevice and the driver callback. The __flow_indr_block_cb_register() call iterates over the list of the front-end callbacks. 2) The front-end callback sets up the flow_block_offload structure and it invokes the driver callback to set up the flow_block. 3) The driver callback now registers the flow_block structure and it returns the flow_block back to the front-end. 4) The front-end gets the flow_block object and it is now ready to offload rules for this tunnel netdevice. A simplified callgraph is represented below. Front-end Driver NETDEV_REGISTER | __flow_indr_block_cb_register(netdev, cb_priv, driver_cb) | [1] .--------------frontend_indr_block_cb(cb_priv, driver_cb) | . setup_flow_block_offload(bo) | [2] driver_cb(bo, cb_priv) -----------. | \/ set up flow_blocks [3] | add rules to flow_block <---------- TC_SETUP_CLSFLOWER [4] == Releasing the indirect flow_block There are two possibilities, either tunnel netdevice is removed or a netdevice (port representor) is removed. === Tunnel netdevice is removed Driver waits for the NETDEV_UNREGISTER event that announces the tunnel netdevice removal. Then, it calls __flow_indr_block_cb_unregister() to remove the flow_block and rules. Callgraph is very similar to the one described above. === Netdevice is removed (port representor) Driver calls __flow_indr_block_cb_unregister() to remove the existing netfilter/tc rule that belong to the tunnel netdevice. = How does the indirect flow_block work after this patchset? Drivers register the indirect flow_block setup callback through flow_indr_dev_register() if they support for offloading tunnel netdevices. == Setting up an indirect flow_block 1) Frontends check if dev->netdev_ops->ndo_setup_tc is unset. If so, frontends call flow_indr_dev_setup_offload(). This call invokes the drivers' indirect flow_block setup callback. 2) The indirect flow_block setup callback sets up a flow_block structure which relates the tunnel netdevice and the driver. 3) The front-end uses flow_block and offload the rules. Note that the operational to set up (non-indirect) flow_block is very similar. == Releasing the indirect flow_block === Tunnel netdevice is removed This calls flow_indr_dev_setup_offload() to set down the flow_block and remove the offloaded rules. This alternate path is exercised if dev->netdev_ops->ndo_setup_tc is unset. === Netdevice is removed (port representor) If a netdevice is removed, then it might need to to clean up the offloaded tc/netfilter rules that belongs to the tunnel netdevice: 1) The driver invokes flow_indr_dev_unregister() when a netdevice is removed. 2) This call iterates over the existing indirect flow_blocks and it invokes the cleanup callback to let the front-end remove the tc/netfilter rules. The cleanup callback already provides the flow_block that the front-end needs to clean up. Front-end Driver | flow_indr_dev_unregister(...) | iterate over list of indirect flow_block and invoke cleanup callback | .----------------------------- | . frontend_flow_block_cleanup(flow_block) . | \/ remove rules to flow_block TC_SETUP_CLSFLOWER = About this patchset This patchset aims to address the existing TC CT problem while simplifying the indirect flow_block infrastructure. Saving 300 LoC in the flow_offload core and the drivers. The operational gets aligned with the (non-indirect) flow_blocks logic. Patchset is composed of: Patch #1 add nf_flow_table_gc_cleanup() which is required by the netfilter's flowtable new indirect flow_block approach. Patch #2 adds the flow_block_indr object which is actually part of of the flow_block object. This stores the indirect flow_block metadata such as the tunnel netdevice owner and the cleanup callback (in case the tunnel netdevice goes away). This patch adds flow_indr_dev_{un}register() to allow drivers to offer netdevice tunnel hardware offload to the front-ends. Then, front-ends call flow_indr_dev_setup_offload() to invoke the drivers to set up the (indirect) flow_block. Patch #3 add the tcf_block_offload_init() helper function, this is a preparation patch to adapt the tc front-end to use this new indirect flow_block infrastructure. Patch #4 updates the tc and netfilter front-ends to use the new indirect flow_block infrastructure. Patch #5 updates the mlx5 driver to use the new indirect flow_block infrastructure. Patch #6 updates the nfp driver to use the new indirect flow_block infrastructure. Patch #7 updates the bnxt driver to use the new indirect flow_block infrastructure. Patch #8 removes the indirect flow_block infrastructure version 1, now that frontends and drivers have been translated to version 2 (coming in this patchset). ==================== Signed-off-by: David S.

2020-06-01net: flow_offload: consolidate indirect flow_block infrastructurePablo Neira Ayuso2-0/+176
Tunnel devices provide no dev->netdev_ops->ndo_setup_tc(...) interface. The tunnel device and route control plane does not provide an obvious way to relate tunnel and physical devices. This patch allows drivers to register a tunnel device offload handler for the tc and netfilter frontends through flow_indr_dev_register() and flow_indr_dev_unregister(). The frontend calls flow_indr_dev_setup_offload() that iterates over the list of drivers that are offering tunnel device hardware offload support and it sets up the flow block for this tunnel device. If the driver module is removed, the indirect flow_block ends up with a stale callback reference. The module removal path triggers the dev_shutdown() path to remove the qdisc and the flow_blocks for the physical devices. However, this is not useful for tunnel devices, where relation between the physical and the tunnel device is not explicit. This patch introduces a cleanup callback that is invoked when the driver module is removed to clean up the tunnel device flow_block. This patch defines struct flow_block_indr and it uses it from flow_block_cb to store the information that front-end requires to perform the flow_block_cb cleanup on module removal.

Bartosz Golaszewski says: ==================== regmap: provide simple bitops and use them in a driver I noticed that oftentimes I use regmap_update_bits() for simple bit setting or clearing. In this case the fourth argument is superfluous as it's always 0 or equal to the mask argument. This series proposes to add simple bit operations for setting, clearing and testing specific bits with regmap. The second patch uses all three in a driver that got recently picked into the net-next tree. The patches obviously target different trees so - if you're ok with the change itself - I propose you pick the first one into your regmap tree for v5.8 and then I'll resend the second patch to add the first user for these macros for v5.9. v1 -> v2: - convert the new macros to static inline functions v2 -> v3: - drop unneeded ternary operator ==================== Signed-off-by: David S.

2020-06-01regmap: provide helpers for simple bit operationsBartosz Golaszewski2-0/+58
In many instances regmap_update_bits() is used for simple bit setting and clearing. In these cases the last argument is redundant and we can hide it with a static inline function. This adds three new helpers for simple bit operations: set_bits, clear_bits and test_bits (the last one defined as a regular function).

See the individual changelogs for detailed explanation of the problem and solution.

2020-06-01vxlan: Avoid infinite loop when suppressing NS messages with invalid optionsIdo Schimmel1-0/+4
When proxy mode is enabled the vxlan device might reply to Neighbor Solicitation (NS) messages on behalf of remote hosts. In case the NS message includes the "Source link-layer address" option [1], the vxlan device will use the specified address as the link-layer destination address in its reply. To avoid an infinite loop, break out of the options parsing loop when encountering an option with length zero and disregard the NS message. This is consistent with the IPv6 ndisc code and RFC 4886 which states that "Nodes MUST silently discard an ND packet that contains an option with length zero" [2].

2020-06-01perf arm-spe: Support synthetic eventsTan Xiaojun5-43/+1097
After the commit ffd3d18c20b8 ("perf tools: Add ARM Statistical Profiling Extensions (SPE) support") has been merged, it supports to output raw data with option "--dump-raw-trace". However, it misses for support synthetic events so cannot output any statistical info. This patch is to improve the "perf report" support for ARM SPE for four types synthetic events: First level cache synthetic events, including L1 data cache accessing and missing events; Last level cache synthetic events, including last level cache accessing and missing events; TLB synthetic events, including TLB accessing and missing events; Remote access events, which is used to account load/store operations caused to another socket. Example usage: $ perf record -c 1024 -e arm_spe_0/branch_filter=1,ts_enable=1,pct_enable=1,pa_enable=1,load_filter=1,jitter=1,store_filter=1,min_latency=0/ dd if=/dev/zero of=/dev/null count=10000 $ perf report --stdio #

2020-06-01perf test: Initialize memory in dwarf-unwindIan Rogers2-0/+9
Avoid a false positive caused by assembly code in arch/x86. In tests, zero the perf_event to avoid uninitialized memory uses. Warnings were caught using clang with -fsanitize=memory.

2020-06-01perf tests: Don't tail call optimize in unwind testIan Rogers1-5/+5
The tail call optimization can unexpectedly make the stack smaller and cause the test to fail.

2020-06-01tools compiler.h: Add attribute to disable tail callsIan Rogers2-0/+15
Tail call optimizations can remove stack frames that are used in unwinding tests. Add an attribute that can be used to disable the tail call optimization. Tested on clang and GCC. Committer notes: Old versions of clang don't like that __attribute__((optimize)), so add an ifdef to make it go away.
