Pull setattr idmapping fix from Christian Brauner: "This contains a simple fix for setattr. When determining the validity of the attributes the ia_{g,u}id fields contain the value that will be written to inode->i_{g,u}id. When the {g,u}id attribute of the file isn't altered and the caller's fs{g,u}id matches the current {g,u}id attribute the attribute change is allowed. The value in ia_{g,u}id does already account for idmapped mounts and will have taken the relevant idmapping into account. So in order to verify that the {g,u}id attribute isn't changed we simple need to compare the ia_{g,u}id value against the inode's i_{g,u}id value. This only has any meaning for idmapped mounts as idmapping helpers are idempotent without them. And for idmapped mounts this really only has a meaning when circular idmappings are used, i.e. mappings where e.g. id 1000 is mapped to id 1001 and id 1001 is mapped to id 1000. Such ciruclar mappings can e.g. be useful when sharing the same home directory between multiple users at the same time. Before this patch we could end up denying legitimate attribute changes and allowing invalid attribute changes when circular mappings are used. To even get into this situation the caller must've been privileged both to create that mapping and to create that idmapped mount. This hasn't been seen in the wild anywhere but came up when expanding the fstest suite during work on a series of hardening patches. All idmapped fstests pass without any regressions and we're adding new tests to verify the behavior of circular mappings. The new tests can be found at [1]" Link: https://lore.kernel.org/linux-fsdevel/20211109145713.1868404-2-brauner@kernel.org [1] * tag 'fs.idmapped.v5.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: fs: handle circular mappings correctly -

John Efstathiades says: =================== lan78xx NAPI Performance Improvements This patch set introduces a set of changes to the lan78xx driver that were originally developed as part of an investigation into the performance of TCP and UDP transfers on an Android system. The changes increase the throughput of both UDP and TCP transfers and reduce the overall CPU load. These improvements are also seen on a standard Linux kernel. Typical results are included at the end of this document. The changes to the driver evolved over time. The patches presented here attempt to organise the changes in to coherent blocks that affect logically connected parts of the driver. The patches do not reflect the way in which the code evolved during the performance investigation. Each patch produces a working driver that has an incremental improvement but patches 2, 3 and 6 should be considered a single update. The changes affect the following parts of the driver: 1. Deferred URB processing The deferred URB processing that was originally done by a tasklet is now done by a NAPI polling routine. The NAPI cycle has a fixed work budget that controls how many received frames are passed to the network stack. Patch 6 introduces the NAPI polling but depends on preceding patches. The new NAPI polling routine is also responsible for submitting Rx and Tx URBs to the USB host controller. Moving the URB processing to a NAPI-based system "smoothed" incoming and outgoing data flows on the Android system under investigation. However, taken in isolation, moving from a tasklet approach to a NAPI approach made little or no difference to the overall performance. 2. URB buffer management The driver creates a pool of Tx and a pool of Rx URB buffers. Each buffer is large enough to accommodate a packet with the maximum MTU data. URBs are allocated from these pools as required. Patch 2 introduces the new Tx buffer pool. Patch 3 introduces the new Rx buffer pool. 3. Tx pending data SKBs containing data to be transmitted are added to a queue. The driver tracks free Tx URBs and the corresponding free Tx URB space. When new Tx URBs are submitted, pending data is copied into the URB buffer until the URB buffer is filled or there is no more pending data. This maximises utilisation the LAN78xx internal USB and network frame buffers. New Tx URBs are submitted to the USB host controller as part of the NAPI polling cycle. Patch 2 introduces these changes. 4. Rx URB completion A new URB is no longer submitted as part of the URB completion callback. New URBs are submitted during the NAPI polling cycle. Patch 3 introduces these changes. 5. Rx URB processing Completed URBs are put on to queue for processing (as is done in the current driver). Network packets in completed URBs are copied from the URB buffer in to dynamically allocated SKBs and passed to the network stack. The emptied URBs are resubmitted to the USB host controller. Patch 3 introduces this change. Patch 6 updates the change to use NAPI SKBs. Each packet passed to the network stack is a single NAPI work item. If the NAPI work budget is exhausted the remaining packets in the URB are put onto an overflow queue that is processed at the start of the next NAPI cycle. Patch 6 introduces this change. 6. Driver-specific hard_header_len The driver-specific hard_header_len adjustment was removed as it broke generic receive offload (GRO) processing. Moreover, it was no longer required due the change in Tx pending data management (see point 3. above). Patch 5 introduces this change. The modification has been tested on four different target machines: Target | CPU | ARCH | cores | kernel | RAM | -----------------+------------+---------+-------+--------+-------| Raspberry Pi 4B | Cortex-A72 | aarch64 | 4 | 64-bit | 2 GB | Nitrogen8M SBC | Cortex-A53 | aarch64 | 4 | 64-bit | 2 GB | Compaq Pressario | Pentium D | i686 | 2 | 32-bit | 4 GB | Dell T3620 | Core i3 | x86_64 | 2+2 | 64-bit | 16 GB | The targets, apart from the Compaq, each have an on-chip USB3 host controller. A PCIe-based USB3 host controller card was added to the Compaq to provide the necessary USB3 host interface. The network throughput was measured using iperf3. The peer device was a second Dell T3620 fitted with an Intel i210 network interface. The target machine and the peer device were connected via a Netgear GS105 gigabit switch. The CPU load was measured using mpstat running on the target machine. The tables below summarise the throughput and CPU load improvements achieved by the updated driver. The bandwidth is the average bandwidth reported by iperf3 at the end of a 60-second test. The percentage idle figure is the average idle reported across all CPU cores on the target machine for the duration of the test.

This patch introduces a NAPI-style approach for processing completed Rx URBs that contributes to improving driver throughput and reducing CPU load. Packets in completed URBs are copied to NAPI SKBs and passed to the network stack for processing. Each frame passed to the stack is one work item in the NAPI budget. If the NAPI budget is consumed and frames remain, they are added to an overflow queue that is processed at the start of the next NAPI polling cycle. The NAPI handler is also responsible for copying pending Tx data to Tx URBs and submitting them to the USB host controller for transmission. Signed-off-by:

This patch introduces a new approach to allocating and managing Rx URBs that contributes to improving driver throughput and reducing CPU load. A pool of Rx URBs is created during driver instantiation. All the URBs are initially submitted to the USB host controller for processing. The default URB buffer size is different for each USB bus speed. The chosen sizes provide good USB utilisation with little impact on overall packet latency. Completed URBs are processed in the driver bottom half. The URB buffer contents are copied to a dynamically allocated SKB, which is then passed to the network stack. The URB is then re-submitted to the USB host controller. NOTE: the call to skb_copy() in rx_process() that copies the URB contents to a new SKB is a temporary change to make this patch work in its own right. This call will be removed when the NAPI processing is introduced by patch 6 in this patch set. Signed-off-by:

This patch introduces a new approach to allocating and managing Tx URBs that contributes to improving driver throughput and reducing CPU load. A pool of Tx URBs is created during driver instantiation. A URB is allocated from the pool when there is data to transmit. The URB is released back to the pool when the data has been transmitted by the device. The default URB buffer size is different for each USB bus speed. The chosen sizes provide good USB utilisation with little impact on overall packet latency. SKBs to be transmitted are added to a pending queue for processing. The driver tracks the available Tx URB buffer space and copies as much pending data as possible into each free URB. Each full URB is then submitted to the USB host controller for transmission.

PSFP rules take effect on the streams from any port of VSC9959 switch. This patch use ingress port to limit the rule only active on this port. Each stream can only match two ingress source ports in VSC9959. Streams from lowest port gets the configuration of SFID pointed by MAC Table lookup and streams from highest port gets the configuration of (SFID+1) pointed by MAC Table lookup. This patch defines the PSFP rule on highest port as dummy rule, which means that it does not modify the MAC table. Signed-off-by:

This patch add police action to set flow meter table which is defined in IEEE802.1Qci. Flow metering is two rates two buckets and three color marker to policing the frames, we only enable one rate one bucket in this patch. Flow metering shares a same policer pool with VCAP policers, so the PSFP policer calls ocelot_vcap_policer_add() and ocelot_vcap_policer_del() to set flow meter police. Signed-off-by:
