https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.4 The Qualcomm SCM driver will now always clear the download bit, avoiding entering download mode on a clean reboot because the bootloader left it set. The vmid bitmap passed to qcom_scm_assign_mem() is transitioned to a well defined size. SM6375 support is added, and SC8180X, QDU1000/QRU1000, IPQ5332 and IPQ9574 compatibles are documented. GENI gains support for newer hardware with deeper FIFOs. The BWMON driver is updated to better handle the two register blocks, which are not consistent between MSM8998 and newer platforms. The LLCC driver no longer assumes a fixes stride across the various banks, and instead acquire the bank placement from DeviceTree. EDAC support for polling is introduced. EDAC support on SDM845 is disabled, as its been observed that accessing relevant registers is not permitted on most devices. PMIC GLINK is reworked to support defining which auxiliary children to spawn per platform, support for spawning a UCSI child is added and SM8450 and SM8550 is introduced. The RPM power-domain driver is cleaned up by moving and generalizing structures that are common between platforms, rather than duplicating everything. Macros are replaced with just direct definition of the relevant structures. Support for defining parent relationships between the power-domains is introduced, like it has been in rpmhpd for a long time. Number of processors has gone up, so max processor count in SMEM is bumped again. Error handling in SMSM is cleaned up using dev_err_probe(). Socinfo is taught about IPQ9574, QCM2290, QRB2210, QRB4210, SM7150, SA8775P and a number of PMICs. * tag 'qcom-drivers-for-6.4' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (51 commits) dt-bindings: firmware: document Qualcomm SC8180X SCM dt-bindings: sram: qcom,imem: document SM6375 IMEM soc: qcom: icc-bwmon: Handle global registers correctly soc: qcom: icc-bwmon: Remove unused struct member soc: qcom: smsm: Use dev_err_probe() firmware: qcom_scm: Add SM6375 compatible soc: qcom: llcc: Add configuration data for SM7150 dt-bindings: arm: msm: Add LLCC for SM7150 dt-bindings: soc: qcom: smd-rpm: re-add missing qcom,rpm-msm8994 soc: qcom: pmic_glink: register ucsi aux device dt-bindings: soc: qcom: qcom,pmic-glink: document SM8550 compatible dt-bindings: soc: qcom: qcom,pmic-glink: document SM8450 compatible firmware: qcom_scm: Clear download bit during reboot dt-bindings: soc: qcom: aoss: Document QDU1000/QRU1000 compatible dt-bindings: firmware: qcom,scm: Update QDU1000/QRU1000 compatible dt-bindings: soc: qcom: smd-rpm: Add IPQ9574 compatible firmware: qcom_scm: Use fixed width src vm bitmap dt-bindings: firmware: qcom,scm: document IPQ5332 SCM dt-bindings: scm: Add compatible for IPQ9574 soc: qcom: rpmpd: Remove useless comments ...

2023-04-14wifi: brcmfmac: add Cypress 43439 SDIO idsMarek Vasut
Add SDIO ids for use with the muRata 1YN (Cypress CYW43439). The odd thing about this is that the previous 1YN populated on M.2 card for evaluation purposes had BRCM SDIO vendor ID, while the chip populated on real hardware has a Cypress one. The device ID also differs between the two devices. But they are both 43439 otherwise, so add the IDs for both. On-device 1YN (43439), the new one, chip label reads "1YN": ``` /sys/.../mmc_host/mmc2/mmc2:0001 # cat vendor device 0x04b4 0xbd3d ``` EA M.2 evaluation board 1YN (43439), the old one, chip label reads "1YN ES1.4": ``` /sys/.../mmc_host/mmc0/mmc0:0001/# cat vendor device 0x02d0 0xa9a6 ``` Reviewed-by: Hans de Goede <hdegoede@redhat.com> Cc: stable@vger.kernel.org Signed-off-by: Marek Vasut <marex@denx.de> Reviewed-by: Simon Horman <simon.horman@corigine.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230407203752.128539-1-marex@denx.de

The cache information can be extracted from either a Device Tree (DT), the PPTT ACPI table, or arch registers (clidr_el1 for arm64). The clidr_el1 register is used only if DT/ACPI information is not available. It does not states how caches are shared among CPUs. Add a use_arch_cache_info field/function to identify when the DT/ACPI doesn't provide cache information. Use this information to assume L1 caches are privates and L2 and higher are shared among all CPUs.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2023-04-11 1) Vlad adds the support for linux bridge multicast offload support Patches #1 through #9 Synopsis Vlad Says: ============== Implement support of bridge multicast offload in mlx5. Handle port object attribute SWITCHDEV_ATTR_ID_BRIDGE_MC_DISABLED notification to toggle multicast offload and bridge snooping support on bridge. Handle port object SWITCHDEV_OBJ_ID_PORT_MDB notification to attach a bridge port to MDB. Steering architecture Existing offload infrastructure relies on two levels of flow tables - bridge ingress and egress. For multicast offload the architecture is extended with additional layer of per-port multicast replication tables. Such tables filter loopback traffic (so packets are not replicated to their source port) and pop VLAN headers for "untagged" VLANs. The tables are referenced by the MDB rules in egress table. MDB egress rule can point to multiple per-port multicast tables, which causes matching multicast traffic to be replicated to all of them, and, consecutively, to several bridge ports: +--------+--+ +---------------------------------------> Port 1 | | | +-^------+--+ | | | | +-----------------------------------------+ | +---------------------------+ | | EGRESS table | | +--> PORT 1 multicast table | | +----------------------------------+ +-----------------------------------------+ | | +---------------------------+ | | INGRESS table | | | | | | | | +----------------------------------+ | dst_mac=P1,vlan=X -> pop vlan, goto P1 +--+ | | FG0: | | | | | dst_mac=P1,vlan=Y -> pop vlan, goto P1 | | | src_port=dst_port -> drop | | | src_mac=M1,vlan=X -> goto egress +---> dst_mac=P2,vlan=X -> pop vlan, goto P2 +--+ | | FG1: | | | ... | | dst_mac=P2,vlan=Y -> goto P2 | | | | VLAN X -> pop, goto port | | | | | dst_mac=MDB1,vlan=Y -> goto mcast P1,P2 +-----+ | ... | | +----------------------------------+ | | | | | VLAN Y -> pop, goto port +-------+ +-----------------------------------------+ | | | FG3: | | | | matchall -> goto port | | | | | | | +---------------------------+ | | | | | | +--------+--+ +---------------------------------------> Port 2 | | | +-^------+--+ | | | | | +---------------------------+ | +--> PORT 2 multicast table | | +---------------------------+ | | | | | FG0: | | | src_port=dst_port -> drop | | | FG1: | | | VLAN X -> pop, goto port | | | ... | | | | | | FG3: | | | matchall -> goto port +-------+ | | +---------------------------+ Patches overview: - Patch 1 adds hardware definition bits for capabilities required to replicate multicast packets to multiple per-port tables. These bits are used by following patches to only attempt multicast offload if firmware and hardware provide necessary support. - Pathces 2-4 patches are preparations and refactoring. - Patch 5 implements necessary infrastructure to toggle multicast offload via SWITCHDEV_ATTR_ID_BRIDGE_MC_DISABLED port object attribute notification. This also enabled IGMP and MLD snooping. - Patch 6 implements per-port multicast replication tables. It only supports filtering of loopback packets. - Patch 7 extends per-port multicast tables with VLAN pop support for 'untagged' VLANs. - Patch 8 handles SWITCHDEV_OBJ_ID_PORT_MDB port object notifications. It creates MDB replication rules in egress table that can replicate packets to multiple per-port multicast tables. - Patch 9 adds tracepoints for MDB events. ============== 2) Parav Create a new allocation profile for SFs, to save on memory 3) Yevgeny provides some initial patches for upcoming software steering support new pattern/arguments type of modify_header actions. Starting with ConnectX-6 DX, we use a new design of modify_header FW object. The current modify_header object allows for having only limited number of these FW objects, which means that we are limited in the number of offloaded flows that require modify_header action. As a preparation Yevgeny provides the following 4 patches: - Patch 1: Add required mlx5_ifc HW bits - Patch 2, 3: Add new WQE type and opcode that is required for pattern/arg support and adds appropriate support in dr_send.c - Patch 4: Add ICM pool for modify-header-pattern objects and implement patterns cache, allowing patterns reuse for different flows * tag 'mlx5-updates-2023-04-11' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: DR, Add modify-header-pattern ICM pool net/mlx5: DR, Prepare sending new WQE type net/mlx5: Add new WQE for updating flow table net/mlx5: Add mlx5_ifc bits for modify header argument net/mlx5: DR, Set counter ID on the last STE for STEv1 TX net/mlx5: Create a new profile for SFs net/mlx5: Bridge, add tracepoints for multicast net/mlx5: Bridge, implement mdb offload net/mlx5: Bridge, support multicast VLAN pop net/mlx5: Bridge, add per-port multicast replication tables net/mlx5: Bridge, snoop igmp/mld packets net/mlx5: Bridge, extract code to lookup parent bridge of port net/mlx5: Bridge, move additional data structures to priv header net/mlx5: Bridge, increase bridge tables sizes net/mlx5: Add mlx5_ifc definitions for bridge multicast support ==================== Link: https://lore.kernel.org/r/20230412040752.14220-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-04-13bpf: Support 64-bit pointers to kfuncsIlya Leoshkevich
test_ksyms_module fails to emit a kfunc call targeting a module on s390x, because the verifier stores the difference between kfunc address and __bpf_call_base in bpf_insn.imm, which is s32, and modules are roughly (1 << 42) bytes away from the kernel on s390x. Fix by keeping BTF id in bpf_insn.imm for BPF_PSEUDO_KFUNC_CALLs, and storing the absolute address in bpf_kfunc_desc. Introduce bpf_jit_supports_far_kfunc_call() in order to limit this new behavior to the s390x JIT. Otherwise other JITs need to be modified, which is not desired. Introduce bpf_get_kfunc_addr() instead of exposing both find_kfunc_desc() and struct bpf_kfunc_desc. In addition to sorting kfuncs by imm, also sort them by offset, in order to handle conflicting imms from different modules. Do this on all architectures in order to simplify code. Factor out resolving specialized kfuncs (XPD and dynptr) from fixup_kfunc_call(). This was required in the first place, because fixup_kfunc_call() uses find_kfunc_desc(), which returns a const pointer, so it's not possible to modify kfunc addr without stripping const, which is not nice. It also removes repetition of code like: if (bpf_jit_supports_far_kfunc_call()) desc->addr = func; else insn->imm = BPF_CALL_IMM(func); and separates kfunc_desc_tab fixups from kfunc_call fixups.

The main changes are: 1) Rework BPF verifier log behavior and implement it as a rotating log by default with the option to retain old-style fixed log behavior, from Andrii Nakryiko. 2) Adds support for using {FOU,GUE} encap with an ipip device operating in collect_md mode and add a set of BPF kfuncs for controlling encap params, from Christian Ehrig. 3) Allow BPF programs to detect at load time whether a particular kfunc exists or not, and also add support for this in light skeleton, from Alexei Starovoitov. 4) Optimize hashmap lookups when key size is multiple of 4, from Anton Protopopov. 5) Enable RCU semantics for task BPF kptrs and allow referenced kptr tasks to be stored in BPF maps, from David Vernet. 6) Add support for stashing local BPF kptr into a map value via bpf_kptr_xchg(). This is useful e.g. for rbtree node creation for new cgroups, from Dave Marchevsky. 7) Fix BTF handling of is_int_ptr to skip modifiers to work around tracing issues where a program cannot be attached, from Feng Zhou. 8) Migrate a big portion of test_verifier unit tests over to test_progs -a verifier_* via inline asm to ease {read,debug}ability, from Eduard Zingerman. 9) Several updates to the instruction-set.rst documentation which is subject to future IETF standardization (https://lwn.net/Articles/926882/), from Dave Thaler. 10) Fix BPF verifier in the __reg_bound_offset's 64->32 tnum sub-register known bits information propagation, from Daniel Borkmann. 11) Add skb bitfield compaction work related to BPF with the overall goal to make more of the sk_buff bits optional, from Jakub Kicinski. 12) BPF selftest cleanups for build id extraction which stand on its own from the upcoming integration work of build id into struct file object, from Jiri Olsa. 13) Add fixes and optimizations for xsk descriptor validation and several selftest improvements for xsk sockets, from Kal Conley. 14) Add BPF links for struct_ops and enable switching implementations of BPF TCP cong-ctls under a given name by replacing backing struct_ops map, from Kui-Feng Lee. 15) Remove a misleading BPF verifier env->bypass_spec_v1 check on variable offset stack read as earlier Spectre checks cover this, from Luis Gerhorst. 16) Fix issues in copy_from_user_nofault() for BPF and other tracers to resemble copy_from_user_nmi() from safety PoV, from Florian Lehner and Alexei Starovoitov. 17) Add --json-summary option to test_progs in order for CI tooling to ease parsing of test results, from Manu Bretelle. 18) Batch of improvements and refactoring to prep for upcoming bpf_local_storage conversion to bpf_mem_cache_{alloc,free} allocator, from Martin KaFai Lau. 19) Improve bpftool's visual program dump which produces the control flow graph in a DOT format by adding C source inline annotations, from Quentin Monnet. 20) Fix attaching fentry/fexit/fmod_ret/lsm to modules by extracting the module name from BTF of the target and searching kallsyms of the correct module, from Viktor Malik. 21) Improve BPF verifier handling of '<const> <cond> <non_const>' to better detect whether in particular jmp32 branches are taken, from Yonghong Song. 22) Allow BPF TCP cong-ctls to write app_limited of struct tcp_sock. A built-in cc or one from a kernel module is already able to write to app_limited, from Yixin Shen.

2023-04-13xdp: rss hash types representationJesper Dangaard Brouer
The RSS hash type specifies what portion of packet data NIC hardware used when calculating RSS hash value. The RSS types are focused on Internet traffic protocols at OSI layers L3 and L4. L2 (e.g. ARP) often get hash value zero and no RSS type. For L3 focused on IPv4 vs. IPv6, and L4 primarily TCP vs UDP, but some hardware supports SCTP. Hardware RSS types are differently encoded for each hardware NIC. Most hardware represent RSS hash type as a number. Determining L3 vs L4 often requires a mapping table as there often isn't a pattern or sorting according to ISO layer. The patch introduce a XDP RSS hash type (enum xdp_rss_hash_type) that contains both BITs for the L3/L4 types, and combinations to be used by drivers for their mapping tables. The enum xdp_rss_type_bits get exposed to BPF via BTF, and it is up to the BPF-programmer to match using these defines. This proposal change the kfunc API bpf_xdp_metadata_rx_hash() adding a pointer value argument for provide the RSS hash type. Change signature for all xmo_rx_hash calls in drivers to make it compile. The RSS type implementations for each driver comes as separate patches.

2023-04-13cacheinfo: Add arch specific early level initializerRadu Rendec
This patch gives architecture specific code the ability to initialize the cache level and allocate cacheinfo memory early, when cache level initialization runs on the primary CPU for all possible CPUs. This is part of a patch series that attempts to further the work in commit 5944ce092b97 ("arch_topology: Build cacheinfo from primary CPU"). Previously, in the absence of any DT/ACPI cache info, architecture specific cache detection and info allocation for secondary CPUs would happen in non-preemptible context during early CPU initialization and trigger a "BUG: sleeping function called from invalid context" splat on an RT kernel. More specifically, this patch adds the early_cache_level() function, which is called by fetch_cache_info() as a fallback when the number of cache leaves cannot be extracted from DT/ACPI. In the default generic (weak) implementation, this new function returns -ENOENT, which preserves the original behavior for architectures that do not implement the function. Since early detection can get the number of cache leaves wrong in some cases*, additional logic is added to still call init_cache_level() later on the secondary CPU, therefore giving the architecture specific code an opportunity to go back and fix the initial guess. Again, the original behavior is preserved for architectures that do not implement the new function. * For example, on arm64, CLIDR_EL1 detection works only when it runs on the current CPU. In other words, a CPU cannot detect the cache depth for any other CPU than itself.

2023-04-12rtnetlink: Restore RTM_NEW/DELLINK notification behaviorMartin Willi
The commits referenced below allows userspace to use the NLM_F_ECHO flag for RTM_NEW/DELLINK operations to receive unicast notifications for the affected link. Prior to these changes, applications may have relied on multicast notifications to learn the same information without specifying the NLM_F_ECHO flag. For such applications, the mentioned commits changed the behavior for requests not using NLM_F_ECHO. Multicast notifications are still received, but now use the portid of the requester and the sequence number of the request instead of zero values used previously. For the application, this message may be unexpected and likely handled as a response to the NLM_F_ACKed request, especially if it uses the same socket to handle requests and notifications. To fix existing applications relying on the old notification behavior, set the portid and sequence number in the notification only if the request included the NLM_F_ECHO flag. This restores the old behavior for applications not using it, but allows unicasted notifications for others.
