net: dsa: felix: add support for changing DSA master
Changing the DSA master means different things depending on the tagging protocol in use. For NPI mode ("ocelot" and "seville"), there is a single port which can be configured as NPI, but DSA only permits changing the CPU port affinity of user ports one by one. So changing a user port to a different NPI port globally changes what the NPI port is, and breaks the user ports still using the old one. To address this while still permitting the change of the NPI port, require that the user ports which are still affine to the old NPI port are down, and cannot be brought up until they are all affine to the same NPI port. The tag_8021q mode ("ocelot-8021q") is more flexible, in that each user port can be freely assigned to one CPU port or to the other. This works by filtering host addresses towards both tag_8021q CPU ports, and then restricting the forwarding from a certain user port only to one of the two tag_8021q CPU ports. Additionally, the 2 tag_8021q CPU ports can be placed in a LAG. This works by enabling forwarding via PGID_SRC from a certain user port towards the logical port ID containing both tag_8021q CPU ports, but then restricting forwarding per packet, via the LAG hash codes in PGID_AGGR, to either one or the other. When we change the DSA master to a LAG device, DSA guarantees us that the LAG has at least one lower interface as a physical DSA master. But DSA masters can come and go as lowers of that LAG, and ds->ops->port_change_master() will not get called, because the DSA master is still the same (the LAG). So we need to hook into the ds->ops->port_lag_{join,leave} calls on the CPU ports and update the logical port ID of the LAG that user ports are assigned to.

net: dsa: propagate extack to port_lag_join
Drivers could refuse to offload a LAG configuration for a variety of reasons, mainly having to do with its TX type. Additionally, since DSA masters may now also be LAG interfaces, and this will translate into a call to port_lag_join on the CPU ports, there may be extra restrictions there. Propagate the netlink extack to this DSA method in order for drivers to give a meaningful error message back to the user.

net: mscc: ocelot: share the common stat definitions between all drivers
All switch families supported by the ocelot lib (ocelot, felix, seville) export the same registers so far. But for example felix also has TSN counters, while the others don't. To reduce the bloat even further, create an OCELOT_COMMON_STATS() macro which just lists all stats that are common between switches. The array elements are still replicated among all of vsc9959_stats_layout, vsc9953_stats_layout and ocelot_stats_layout.

net: mscc: ocelot: minimize definitions for stats
The current definition of struct ocelot_stat_layout is long-winded (4 lines per entry, and we have hundreds of entries), so we could make an effort to use the C preprocessor and reduce the line count. Create an implicit correspondence between enum ocelot_reg, which tells us the register address (SYS_COUNT_RX_OCTETS etc) and enum ocelot_stat which allows us to index the ocelot->stats array (OCELOT_STAT_RX_OCTETS etc), and don't require us to specify both when we define what stats each switch family has. Create an OCELOT_STAT() macro that pairs only an enum ocelot_stat to an enum ocelot_reg, and an OCELOT_STAT_ETHTOOL() macro which also contains a name exported to the unstructured ethtool -S stringset API. For now, we define all counters as having the OCELOT_STAT_ETHTOOL() kind, but we will add more counters in the future which are not exported to the unstructured ethtool -S.

net: mscc: ocelot: add support for all sorts of standardized counters present in DSA
DSA is integrated with the new standardized ethtool -S --groups option, but the felix driver only exports unstructured statistics. Reuse the array of 64-bit statistics collected by ocelot_check_stats_work(), but just export select values from it. Since ocelot_check_stats_work() runs periodically to avoid 32-bit overflow, and the ethtool calling context is sleepable, we update the 64-bit stats one more time, to provide up-to-date values. The locking scheme with a mutex followed by a spinlock is a bit hard to digest, so we create and use a ocelot_port_stats_run() helper with a callback that populates the ethool stats group the caller is interested in. The exported stats are: ethtool -S swp0 --groups eth-phy ethtool -S swp0 --groups eth-mac ethtool -S swp0 --groups eth-ctrl ethtool -S swp0 --groups rmon ethtool --include-statistics --show-pause swp0 Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

net: dsa: felix: check the 32-bit PSFP stats against overflow
The Felix PSFP counters suffer from the same problem as the ocelot ndo_get_stats64 ones - they are 32-bit, so they can easily overflow and this can easily go undetected. Add a custom hook in ocelot_check_stats_work() through which driver specific actions can be taken, and update the stats for the existing PSFP filters from that hook. Previously, vsc9959_psfp_filter_add() and vsc9959_psfp_filter_del() were serialized with respect to each other via rtnl_lock(). However, with the new entry point into &psfp->sfi_list coming from the periodic worker, we now need an explicit mutex to serialize access to these lists. We used to keep a struct felix_stream_filter_counters on stack, through which vsc9959_psfp_stats_get() - a FLOW_CLS_STATS callback - would retrieve data from vsc9959_psfp_counters_get(). We need to become smarter about that in 3 ways: - we need to keep a persistent set of counters for each stream instead of keeping them on stack - we need to promote those counters from u32 to u64, and create a procedure that properly keeps 64-bit counters. Since we clear the hardware counters anyway, and we poll every 2 seconds, a simple increment of a u64 counter with a u32 value will perfectly do the job. - FLOW_CLS_STATS also expect incremental counters, so we also need to zeroize our u64 counters every time sch_flower calls us Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

To support SPI-controlled switches in the future, access to SYS_STAT_CFG_STAT_VIEW needs to be done outside of any spinlock protected region, but it still needs to be serialized (by a mutex).

TSN stream (802.1Qci, 802.1CB) filters are also accessed through STAT_VIEW, just like the port registers, but these counters are per stream, rather than per port. So we don't keep them in ocelot_port_update_stats().

ARM: at91: pm: fix DDR recalibration when resuming from backup and self-refresh
On SAMA7G5, when resuming from backup and self-refresh, the bootloader
performs DDR PHY recalibration by restoring the value of ZQ0SR0 (stored
in RAM by Linux before going to backup and self-refresh). It has been
discovered that the current procedure doesn't work for all possible values
that might go to ZQ0SR0 due to hardware bug. The workaround to this is to
avoid storing some values in ZQ0SR0. Thus Linux will read the ZQ0SR0
register and cache its value in RAM after processing it (using
modified_gray_code array). The bootloader will restore the processed value.

ARM: at91: pm: fix self-refresh for sama7g5
It has been discovered that on some parts, from time to time, self-refresh
procedure doesn't work as expected. Debugging and investigating it proved
that disabling AC DLL introduce glitches in RAM controllers which
leads to unexpected behavior. This is confirmed as a hardware bug. DLL
bypass disables 3 DLLs: 2 DX DLLs and AC DLL. Thus, keep only DX DLLs
disabled. This introduce 6mA extra current consumption on VDDCORE when
switching to any ULP mode or standby mode but the self-refresh procedure
still works.

net: mscc: ocelot: keep ocelot_stat_layout by reg address, not offset
With so many counter addresses recently discovered as being wrong, it is desirable to at least have a central database of information, rather than two: one through the SYS_COUNT_* registers (used for ndo_get_stats64), and the other through the offset field of struct ocelot_stat_layout elements (used for ethtool -S). The strategy will be to keep the SYS_COUNT_* definitions as the single source of truth, but for that we need to expand our current definitions to cover all registers. Then we need to convert the ocelot region creation logic, and stats worker, to the read semantics imposed by going through SYS_COUNT_* absolute register addresses, rather than offsets of 32-bit words relative to SYS_COUNT_RX_OCTETS (which should have been SYS_CNT, by the way).

net: mscc: ocelot: make struct ocelot_stat_layout array indexable
The ocelot counters are 32-bit and require periodic reading, every 2 seconds, by ocelot_port_update_stats(), so that wraparounds are detected. Currently, the counters reported by ocelot_get_stats64() come from the 32-bit hardware counters directly, rather than from the 64-bit accumulated ocelot->stats, and this is a problem for their integrity. The strategy is to make ocelot_get_stats64() able to cherry-pick individual stats from ocelot->stats the way in which it currently reads them out from SYS_COUNT_* registers. But currently it can't, because ocelot->stats is an opaque u64 array that's used only to feed data into ethtool -S. To solve that problem, we need to make ocelot->stats indexable, and associate each element with an element of struct ocelot_stat_layout used by ethtool -S. This makes ocelot_stat_layout a fat (and possibly sparse) array, so we need to change the way in which we access it. We no longer need OCELOT_STAT_END as a sentinel, because we know the array's size (OCELOT_NUM_STATS). We just need to skip the array elements that were left unpopulated for the switch revision (ocelot, felix, seville).

net: mscc: ocelot: fix incorrect ndo_get_stats64 packet counters
Reading stats using the SYS_COUNT_* register definitions is only used by ocelot_get_stats64() from the ocelot switchdev driver, however, currently the bucket definitions are incorrect. Separately, on both RX and TX, we have the following problems: - a 256-1023 bucket which actually tracks the 256-511 packets - the 1024-1526 bucket actually tracks the 512-1023 packets - the 1527-max bucket actually tracks the 1024-1526 packets => nobody tracks the packets from the real 1527-max bucket Additionally, the RX_PAUSE, RX_CONTROL, RX_LONGS and RX_CLASSIFIED_DROPS all track the wrong thing. However this doesn't seem to have any consequence, since ocelot_get_stats64() doesn't use these. Even though this problem only manifests itself for the switchdev driver, we cannot split the fix for ocelot and for DSA, since it requires fixing the bucket definitions from enum ocelot_reg, which makes us necessarily adapt the structures from felix and seville as well.

net: dsa: felix: update base time of time-aware shaper when adjusting PTP time
When adjusting the PTP clock, the base time of the TAS configuration will become unreliable. We need reset the TAS configuration by using a new base time. For example, if the driver gets a base time 0 of Qbv configuration from user, and current time is 20000. The driver will set the TAS base time to be 20000. After the PTP clock adjustment, the current time becomes 10000. If the TAS base time is still 20000, it will be a future time, and TAS entry list will stop running. Another example, if the current time becomes to be 10000000 after PTP clock adjust, a large time offset can cause the hardware to hang. This patch introduces a tas_clock_adjust() function to reset the TAS module by using a new base time after the PTP clock adjustment. This can avoid issues above. Due to PTP clock adjustment can occur at any time, it may conflict with the TAS configuration. We introduce a new TAS lock to serialize the access to the TAS registers.

crypto: caam - add in-kernel interface for blob generator
The NXP Cryptographic Acceleration and Assurance Module (CAAM) can be used to protect user-defined data across system reboot: - When the system is fused and boots into secure state, the master key is a unique never-disclosed device-specific key - random key is encrypted by key derived from master key - data is encrypted using the random key - encrypted data and its encrypted random key are stored alongside - This blob can now be safely stored in non-volatile memory On next power-on: - blob is loaded into CAAM - CAAM writes decrypted data either into memory or key register Add functions to realize encrypting and decrypting into memory alongside the CAAM driver. They will be used in a later commit as a source for the trusted key seal/unseal mechanism.

net: dsa: felix: tag_8021q preparation for multiple CPU ports
Update the VCAP filters to support multiple tag_8021q CPU ports. TX works using a filter for VLAN ID on the ingress of the CPU port, with a redirect and a VLAN pop action. This can be updated trivially by amending the ingress port mask of this rule to match on all tag_8021q CPU ports. RX works using a filter for ingress port on the egress of the CPU port, with a VLAN push action. Here we need to replicate these filters for each tag_8021q CPU port, and let them all have the same action. This means that the OCELOT_VCAP_ES0_TAG_8021Q_RXVLAN() cookie needs to encode a unique value for every {user port, CPU port} pair it's given. Do this by encoding the CPU port in the upper 16 bits of the cookie, and the user port in the lower 16 bits. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

net: mscc: ocelot: switch from {,un}set to {,un}assign for tag_8021q CPU ports
There is a desire for the felix driver to gain support for multiple tag_8021q CPU ports, but the current model prevents it. This is because ocelot_apply_bridge_fwd_mask() only takes into consideration whether a port is a tag_8021q CPU port, but not whose CPU port it is. We need a model where we can have a direct affinity between an ocelot port and a tag_8021q CPU port. This serves as the basis for multiple CPU ports. Declare a "dsa_8021q_cpu" backpointer in struct ocelot_port which encodes that affinity. Repurpose the "ocelot_set_dsa_8021q_cpu" API to "ocelot_assign_dsa_8021q_cpu" to express the change of paradigm. Note that this change makes the first practical use of the new ocelot_port->index field in ocelot_port_unassign_dsa_8021q_cpu(), where we need to remove the old tag_8021q CPU port from the reserved VLAN range.

net: dsa: felix: update bridge fwd mask from ocelot lib when changing tag_8021q CPU
Add more logic to ocelot_port_{,un}set_dsa_8021q_cpu() from the ocelot switch lib by encapsulating the ocelot_apply_bridge_fwd_mask() call that felix used to have. This is necessary because the CPU port change procedure will also need to do this, and it's good to reduce code duplication by having an entry point in the ocelot switch lib that does all that is needed.

Update devfreq next for v5.19
Detailed description for this pull request: 1. Update devfreq core - Add cpu based scaling support to passive governor. Some device like cache might require the dynamic frequency scaling. But, it has very tightly to cpu frequency. So that use passive governor to scale the frequency according to current cpu frequency. To decide the frequency of the device, the governor does one of the following: : Derives the optimal devfreq device opp from required-opps property of the parent cpu opp_table. : Scales the device frequency in proportion to the CPU frequency. So, if the CPUs are running at their max frequency, the device runs at its max frequency. If the CPUs are running at their min frequency, the device runs at its min frequency. It is interpolated for frequencies in between. 2. Update devfreq driver - Update rk3399_dmc.c as following: : Convert dt-binding document to YAML and deprecate unused properties. : Use Hz units for the device-tree properties of rk3399_dmc. : rk3399_dmc is able to set the idle time before changing the dmc clock. Specify idle time parameters by using nano-second unit on dt bidning. : Add new disable-freq properties to optimize the power-saving feature of rk3399_dmc. : Disable devfreq-event device on remove() to fix unbalanced enable-disable count. : Use devm_pm_opp_of_add_table() : Block PMU (Power-Management Unit) transitions when scaling frequency by ARM Trust Firmware in order to fix the conflict between PMU and DMC (Dynamic Memory Controller). -----BEGIN PGP SIGNATURE----- iQJKBAABCgA0FiEEsSpuqBtbWtRe4rLGnM3fLN7rz1MFAmKDddYWHGN3MDAuY2hv aUBzYW1zdW5nLmNvbQAKCRCczd8s3uvPU1o0EACGE7FV/pA/sbOFhhLXQlI1XMQf C2XVvjigP5M7Y9qgM6qLBKCSmRPbBjuO4VLKkIycmo2GRcUs+Sk5CqALjWZF0tDR aiAV+P3wIC2pCZNtAXJG6BhP5GNzGYYdv2zJfNmVUsYUYVC3ezppuE1Yp2Sscq5t K43eAOq0c9+TTeLfdDKdi07QtevMHwbOxjNUhwnzN5+yD9cknK1Ht5FVjDc8eYTG yBJPgMy9qhNqEZ4gl9zpKJkpAJMOhquT4ZtytNioIfnmKCrpyiOy+yApvW5WiU1d /8KMiG42C47rUBYCiEGEdn6PaTOpuOK0hnuoxlxE07dqJP349SbozFTqZxfbCJhI OjZSdLTolPFq82zuAafBJmijmeAiYdI0FKrhXmQo4doeleIQG9z0h8YpkQSnF47L xsj7QswD0LxtMQbYv5zds1NoGnUn/U+TpoJ8mbpg5gPWKaBTNdTZFJQj+HXtrDyy 1ouR41u6kOoLLDHu2I5f9dTMptJRg3jS+kQfDv17K8u5mAmcwFidpOiyac6m2xad Nnn85NAE9JaxpzVe3+S3uQdscEe2FBWEZCkbrCcPn2T88BZwrfcby02YRBw22WkS p4xPAOncw4lhZ6z3pedcH/1+kk6uoTube5QK8ddSRxYrRavtOsqchAaec+hYRNif CbjJOqsdbDLa7ANLxw== =/3W8 -----END PGP SIGNATURE----- Merge tag 'devfreq-next-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux Pull devfreq changes for 5.19-rc1 from Chanwoo Choi: "1.

net: mscc: ocelot: move ocelot_port_private :: chip_port to ocelot_port :: index
Currently the ocelot switch lib is unaware of the index of a struct ocelot_port, since that is kept in the encapsulating structures of outer drivers (struct dsa_port :: index, struct ocelot_port_private :: chip_port). With the upcoming increase in complexity associated with assigning DSA tag_8021q CPU ports to certain user ports, it becomes necessary for the switch lib to be able to retrieve the index of a certain ocelot_port. Therefore, introduce a new u8 to ocelot_port (same size as the chip_port used by the ocelot switchdev driver) and rework the existing code to populate and use it.

soc: rockchip: power-domain: Manage resource conflicts with firmware
On RK3399 platforms, power domains are managed mostly by the kernel (drivers/soc/rockchip/pm_domains.c), but there are a few exceptions where ARM Trusted Firmware has to be involved: (1) system suspend/resume (2) DRAM DVFS (a.k.a., "ddrfreq") Exception (1) does not cause much conflict, since the kernel has quiesced itself by the time we make the relevant PSCI call. Exception (2) can cause conflict, because of two actions: (a) ARM Trusted Firmware needs to read/modify/write the PMU_BUS_IDLE_REQ register to idle the memory controller domain; the kernel driver also has to touch this register for other domains. (b) ARM Trusted Firmware needs to manage the clocks associated with these domains. To elaborate on (b): idling a power domain has always required ungating an array of clocks; see this old explanation from Rockchip: https://lore.kernel.org/linux-arm-kernel/54503C19.9060607@rock-chips.com/ Historically, ARM Trusted Firmware has avoided this issue by using a special PMU_CRU_GATEDIS_CON0 register -- this register ungates all the necessary clocks -- when idling the memory controller. Unfortunately, we've found that this register is not 100% sufficient; it does not turn the relevant PLLs on [0]. So it's possible to trigger issues with something like the following: 1. enable a power domain (e.g., RK3399_PD_VDU) -- kernel will temporarily enable relevant clocks/PLLs, then turn them back off 2. a PLL (e.g., PLL_NPLL) is part of the clock tree for RK3399_PD_VDU's clocks but otherwise unused; NPLL is disabled 3. perform a ddrfreq transition (rk3399_dmcfreq_target() -> ... drivers/clk/rockchip/clk-ddr.c / ROCKCHIP_SIP_DRAM_FREQ) 4. ARM Trusted Firmware unagates VDU clocks (via PMU_CRU_GATEDIS_CON0) 5. ARM Trusted firmware idles the memory controller domain 6. Step 5 waits on the VDU domain/clocks, but NPLL is still off i.e., we hang the system. So for (b), we need to at a minimum manage the relevant PLLs on behalf of firmware. It's easier to simply manage the whole clock tree, in a similar way we do in rockchip_pd_power(). For (a), we need to provide mutual exclusion betwen rockchip_pd_power() and firmware. To resolve that, we simply grab the PMU mutex and release it when ddrfreq is done. The Chromium OS kernel has been carrying versions of part of this hack for a while, based on some new custom notifiers [1]. I've rewritten as a simple function call between the drivers, which is OK because: * the PMU driver isn't enabled, and we don't have this problem at all (the firmware should have left us in an OK state, and there are no runtime conflicts); or * the PMU driver is present, and is a single instance. And the power-domain driver cannot be removed, so there's no lifetime management to worry about. For completeness, there's a 'dmc_pmu_mutex' to guard (likely theoretical?) probe()-time races. It's OK for the memory controller driver to start running before the PMU, because the PMU will avoid any critical actions during the block() sequence. [0] The RK3399 TRM for PMU_CRU_GATEDIS_CON0 only talks about ungating clocks. Based on experimentation, we've found that it does not power up the necessary PLLs. [1] CHROMIUM: soc: rockchip: power-domain: Add notifier to dmc driver https://chromium-review.googlesource.com/q/I242dbd706d352f74ff706f5cbf42ebb92f9bcc60 Notably, the Chromium solution only handled conflict (a), not (b). In practice, item (b) wasn't a problem in many cases because we never managed to fully power off PLLs. Now that the (upstream) video decoder driver performs runtime clock management, we often power off NPLL.

net: mscc: ocelot: mark traps with a bool instead of keeping them in a list
Since the blamed commit, VCAP filters can appear on more than one list.
If their action is "trap", they are chained on ocelot->traps via
filter->trap_list. This is in addition to their normal placement on the
VCAP block->rules list head.
Therefore, when we free a VCAP filter, we must remove it from all lists
it is a member of, including ocelot->traps.
There are at least 2 bugs which are direct consequences of this design
decision.
First is the incorrect usage of list_empty(), meant to denote whether
"filter" is chained into ocelot->traps via filter->trap_list.
This does not do the correct thing, because list_empty() checks whether
"head->next == head", but in our case, head->next == head->prev == NULL.
So we dereference NULL pointers and die when we call list_del().
Second is the fact that not all places that should remove the filter
from ocelot->traps do so. One example is ocelot_vcap_block_remove_filter(),
which is where we have the main kfree(filter). By keeping freed filters
in ocelot->traps we end up in a use-after-free in
felix_update_trapping_destinations().
Attempting to fix all the buggy patterns is a whack-a-mole game which
makes the driver unmaintainable. Actually this is what the previous
patch version attempted to do:
https://patchwork.kernel.org/project/netdevbpf/patch/20220503115728.834457-3-vladimir.oltean@nxp.com/
but it introduced another set of bugs, because there are other places in
which create VCAP filters, not just ocelot_vcap_filter_create():
- ocelot_trap_add()
- felix_tag_8021q_vlan_add_rx()
- felix_tag_8021q_vlan_add_tx()
Relying on the convention that all those code paths must call
INIT_LIST_HEAD(&filter->trap_list) is not going to scale.
So let's do what should have been done in the first place and keep a
bool in struct ocelot_vcap_filter which denotes whether we are looking
at a trapping rule or not. Iterating now happens over the main VCAP IS2
block->rules. The advantage is that we no longer risk having stale
references to a freed filter, since it is only present in that list.

net: ethernet: ocelot: remove the need for num_stats initializer
There is a desire to share the oclot_stats_layout struct outside of the current vsc7514 driver. In order to do so, the length of the array needs to be known at compile time, and defined in the struct ocelot and struct felix_info. Since the array is defined in a .c file and would be declared in the header file via: extern struct ocelot_stat_layout[]; the size of the array will not be known at compile time to outside modules. To fix this, remove the need for defining the number of stats at compile time and allow this number to be determined at initialization.

Networking changes for 5.18.
Core ---- - Introduce XDP multi-buffer support, allowing the use of XDP with jumbo frame MTUs and combination with Rx coalescing offloads (LRO). - Speed up netns dismantling (5x) and lower the memory cost a little. Remove unnecessary per-netns sockets. Scope some lists to a netns. Cut down RCU syncing. Use batch methods. Allow netdev registration to complete out of order. - Support distinguishing timestamp types (ingress vs egress) and maintaining them across packet scrubbing points (e.g. redirect). - Continue the work of annotating packet drop reasons throughout the stack. - Switch netdev error counters from an atomic to dynamically allocated per-CPU counters. - Rework a few preempt_disable(), local_irq_save() and busy waiting sections problematic on PREEMPT_RT. - Extend the ref_tracker to allow catching use-after-free bugs. BPF --- - Introduce "packing allocator" for BPF JIT images. JITed code is marked read only, and used to be allocated at page granularity. Custom allocator allows for more efficient memory use, lower iTLB pressure and prevents identity mapping huge pages from getting split. - Make use of BTF type annotations (e.g. __user, __percpu) to enforce the correct probe read access method, add appropriate helpers. - Convert the BPF preload to use light skeleton and drop the user-mode-driver dependency. - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling its use as a packet generator. - Allow local storage memory to be allocated with GFP_KERNEL if called from a hook allowed to sleep. - Introduce fprobe (multi kprobe) to speed up mass attachment (arch bits to come later). - Add unstable conntrack lookup helpers for BPF by using the BPF kfunc infra. - Allow cgroup BPF progs to return custom errors to user space. - Add support for AF_UNIX iterator batching. - Allow iterator programs to use sleepable helpers. - Support JIT of add, and, or, xor and xchg atomic ops on arm64. - Add BTFGen support to bpftool which allows to use CO-RE in kernels without BTF info. - Large number of libbpf API improvements, cleanups and deprecations. Protocols --------- - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev. - Adjust TSO packet sizes based on min_rtt, allowing very low latency links (data centers) to always send full-sized TSO super-frames. - Make IPv6 flow label changes (AKA hash rethink) more configurable, via sysctl and setsockopt. Distinguish between server and client behavior. - VxLAN support to "collect metadata" devices to terminate only configured VNIs. This is similar to VLAN filtering in the bridge. - Support inserting IPv6 IOAM information to a fraction of frames. - Add protocol attribute to IP addresses to allow identifying where given address comes from (kernel-generated, DHCP etc.) - Support setting socket and IPv6 options via cmsg on ping6 sockets. - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS. Define dscp_t and stop taking ECN bits into account in fib-rules. - Add support for locked bridge ports (for 802.1X). - tun: support NAPI for packets received from batched XDP buffs, doubling the performance in some scenarios. - IPv6 extension header handling in Open vSwitch. - Support IPv6 control message load balancing in bonding, prevent neighbor solicitation and advertisement from using the wrong port. Support NS/NA monitor selection similar to existing ARP monitor. - SMC - improve performance with TCP_CORK and sendfile() - support auto-corking - support TCP_NODELAY - MCTP (Management Component Transport Protocol) - add user space tag control interface - I2C binding driver (as specified by DMTF DSP0237) - Multi-BSSID beacon handling in AP mode for WiFi. - Bluetooth: - handle MSFT Monitor Device Event - add MGMT Adv Monitor Device Found/Lost events - Multi-Path TCP: - add support for the SO_SNDTIMEO socket option - lots of selftest cleanups and improvements - Increase the max PDU size in CAN ISOTP to 64 kB. Driver API ---------- - Add HW counters for SW netdevs, a mechanism for devices which offload packet forwarding to report packet statistics back to software interfaces such as tunnels. - Select the default NIC queue count as a fraction of number of physical CPU cores, instead of hard-coding to 8. - Expose devlink instance locks to drivers. Allow device layer of drivers to use that lock directly instead of creating their own which always runs into ordering issues in devlink callbacks. - Add header/data split indication to guide user space enabling of TCP zero-copy Rx. - Allow configuring completion queue event size. - Refactor page_pool to enable fragmenting after allocation. - Add allocation and page reuse statistics to page_pool. - Improve Multiple Spanning Trees support in the bridge to allow reuse of topologies across VLANs, saving HW resources in switches. - DSA (Distributed Switch Architecture): - replay and offload of host VLAN entries - offload of static and local FDB entries on LAG interfaces - FDB isolation and unicast filtering New hardware / drivers ---------------------- - Ethernet: - LAN937x T1 PHYs - Davicom DM9051 SPI NIC driver - Realtek RTL8367S, RTL8367RB-VB switch and MDIO - Microchip ksz8563 switches - Netronome NFP3800 SmartNICs - Fungible SmartNICs - MediaTek MT8195 switches - WiFi: - mt76: MediaTek mt7916 - mt76: MediaTek mt7921u USB adapters - brcmfmac: Broadcom BCM43454/6 - Mobile: - iosm: Intel M.2 7360 WWAN card Drivers ------- - Convert many drivers to the new phylink API built for split PCS designs but also simplifying other cases. - Intel Ethernet NICs: - add TTY for GNSS module for E810T device - improve AF_XDP performance - GTP-C and GTP-U filter offload - QinQ VLAN support - Mellanox Ethernet NICs (mlx5): - support xdp->data_meta - multi-buffer XDP - offload tc push_eth and pop_eth actions - Netronome Ethernet NICs (nfp): - flow-independent tc action hardware offload (police / meter) - AF_XDP - Other Ethernet NICs: - at803x: fiber and SFP support - xgmac: mdio: preamble suppression and custom MDC frequencies - r8169: enable ASPM L1.2 if system vendor flags it as safe - macb/gem: ZynqMP SGMII - hns3: add TX push mode - dpaa2-eth: software TSO - lan743x: multi-queue, mdio, SGMII, PTP - axienet: NAPI and GRO support - Mellanox Ethernet switches (mlxsw): - source and dest IP address rewrites - RJ45 ports - Marvell Ethernet switches (prestera): - basic routing offload - multi-chain TC ACL offload - NXP embedded Ethernet switches (ocelot & felix): - PTP over UDP with the ocelot-8021q DSA tagging protocol - basic QoS classification on Felix DSA switch using dcbnl - port mirroring for ocelot switches - Microchip high-speed industrial Ethernet (sparx5): - offloading of bridge port flooding flags - PTP Hardware Clock - Other embedded switches: - lan966x: PTP Hardward Clock - qca8k: mdio read/write operations via crafted Ethernet packets - Qualcomm 802.11ax WiFi (ath11k): - add LDPC FEC type and 802.11ax High Efficiency data in radiotap - enable RX PPDU stats in monitor co-exist mode - Intel WiFi (iwlwifi): - UHB TAS enablement via BIOS - band disablement via BIOS - channel switch offload - 32 Rx AMPDU sessions in newer devices - MediaTek WiFi (mt76): - background radar detection - thermal management improvements on mt7915 - SAR support for more mt76 platforms - MBSSID and 6 GHz band on mt7915 - RealTek WiFi: - rtw89: AP mode - rtw89: 160 MHz channels and 6 GHz band - rtw89: hardware scan - Bluetooth: - mt7921s: wake on Bluetooth, SCO over I2S, wide-band-speed (WBS) - Microchip CAN (mcp251xfd): - multiple RX-FIFOs and runtime configurable RX/TX rings - internal PLL, runtime PM handling simplification - improve chip detection and error handling after wakeup Signed-off-by: Jakub Kicinski <kuba@kernel.org> -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE6jPA+I1ugmIBA4hXMUZtbf5SIrsFAmI7YBcACgkQMUZtbf5S IrveSBAAmSNJlUK6vPsnNzs7IhsZnfI/AUjm2TCLZnlhKttbpI4A/4Pohk33V7RS FGX7f8kjEfhUwrIiLDgeCnztNHRECrCmk6aZc/jLEvecmTauJ+f6kjShkDY/wix+ AkPHmrZnQeLPAEVuljDdV+sL6ik08+zQL7PazIYHsaSKKC0MGQptRwcri8PLRAKE KPBAhVhleq2rAZ/ntprSN52F4Af6rpFTrPIWuN8Bqdbc9dy5094LT0mpOOWYvgr3 /DLvvAPuLemwyIQkjWknVKBRUAQcmNPC+BY3J8K3LRaiNhekGqOFan46BfqP+k2J 6DWu0Qrp2yWt4BMOeEToZR5rA6v5suUAMIBu8PRZIDkINXQMlIxHfGjZyNm0rVfw 7edNri966yus9OdzwPa32MIG3oC6PnVAwYCJAjjBMNS8sSIkp7wgHLkgWN4UFe2H K/e6z8TLF4UQ+zFM0aGI5WZ+9QqWkTWEDF3R3OhdFpGrznna0gxmkOeV2YvtsgxY cbS0vV9Zj73o+bYzgBKJsw/dAjyLdXoHUGvus26VLQ78S/VGunVKtItwoxBAYmZo krW964qcC89YofzSi8RSKLHuEWtNWZbVm8YXr75u6jpr5GhMBu0CYefLs+BuZcxy dw8c69cGneVbGZmY2J3rBhDkchbuICl8vdUPatGrOJAoaFdYKuw= =ELpe -----END PGP SIGNATURE----- Merge tag 'net-next-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "The sprinkling of SPI drivers is because we added a new one and Mark sent us a SPI driver interface conversion pull request.

At the moment this is still incomplete as other portions are merged through different trees. - Long abandoned support for running NOMMU ARMv4 or ARMv5 platforms gets removed, now the Arm NOMMU platforms are limited to the Cortex-M family of microcontrollers - Two old PXA boards get removed, along with corresponding driver bits. - Continued cleanup of the Intel IXP4xx platforms, removing some remnants of the old board files. - Minor Cleanups and fixes for Orion, PXA, MMP, Mstar, Samsung - CPU idle support for AT91 - A system controller driver for Polarfire -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmI7I0sACgkQmmx57+YA GNkfsQ/+KHy6byGCcPiB3T+be2/WFnc7ANnniYku4o27703BpROLCltNAr4VTiyM Ucin72wmuPx840RiP0o8st7D9Ms7fG3/j4hoxJDG6v1aHr8CazCSPZR2EgVAOVeD n4jGuLzICqP3RLw/qdfTT4lARKGqKBW1l5ss0D4PxFECyKq6kzqEOt9wCw29vAJy Vw8CmcDhGr9sI8voZYN1dMyIV4FujkmOm/mNSHNTKKN0vt+GFU0gVxDAG2i7Rh1g cO7593Vg/U4daw97231uoW0q+9vZ6OKajZt1Mm6LFe4AsGRpV+eN5UpQeZzkm7ET D6GFE8/NTkcJHm50OYYER7t69uHe1O/Sf5+MIax1l5pthuWRZGolb1xOBeWJ9Al7 Qgym9XNCGf0AoaUeXIuxVbhxNp8GXqBzL35qMK1hV4WkdrJSRGq+2GQLBgtb6owi ZIpDYAFnUNFkYFdtX5qez8zXy4LHtUf5bO+qnLXPT2Sk0MtYWx9Gn0P4kgMqezkn HQg1inPRQS7PB40xE+7Ap3pzvE/1IWgYblsS8CFekJ4+Nm0X4IRx6/s9KEDHU1ZQ RADI6jwwVe/ioOSNen7S60GNrFKDyt9ZbLq/+x/GE3SkmdTeAmcd+RPmQvc5SHnl jvUnjN1nsyqhOICIGMwvdkFkW749/af713xoiXyCUedZKIxAgkc= =2fmA -----END PGP SIGNATURE----- Merge tag 'arm-soc-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC updates from Arnd Bergmann: "SoC specific code is generally used for older platforms that don't (yet) use device tree to do the same things. - Support is added for i.MXRT10xx, a Cortex-M7 based microcontroller from NXP.
