https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/fixes Qualcomm driver fixes for v6.14 Fixes a locking issue in the PDR implementation, which manifest itself as transaction timeouts during the startup procedure for some remoteprocs. A registration race is fixed in the custom efivars implementation, resolving reported NULL pointer dereferences. Error handling related to tzmem allocation is corrected, to ensure that the allocation error is propagated. Lastly a trivial merge mistake in pmic_glink is addressed. * tag 'qcom-drivers-fixes-for-6.14' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: pdr: Fix the potential deadlock firmware: qcom: uefisecapp: fix efivars registration race firmware: qcom: scm: Fix error code in probe() soc: qcom: pmic_glink: Drop redundant pg assignment before taking lock Link: https://lore.kernel.org/r/20250311022509.1232678-1-andersson@kernel.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2025-02-14soc: qcom: pdr: Fix the potential deadlockSaranya R
When some client process A call pdr_add_lookup() to add the look up for the service and does schedule locator work, later a process B got a new server packet indicating locator is up and call pdr_locator_new_server() which eventually sets pdr->locator_init_complete to true which process A sees and takes list lock and queries domain list but it will timeout due to deadlock as the response will queued to the same qmi->wq and it is ordered workqueue and process B is not able to complete new server request work due to deadlock on list lock. Fix it by removing the unnecessary list iteration as the list iteration is already being done inside locator work, so avoid it here and just call schedule_work() here. Process A Process B process_scheduled_works() pdr_add_lookup() qmi_data_ready_work() process_scheduled_works() pdr_locator_new_server() pdr->locator_init_complete=true; pdr_locator_work() mutex_lock(&pdr->list_lock); pdr_locate_service() mutex_lock(&pdr->list_lock); pdr_get_domain_list() pr_err("PDR: %s get domain list txn wait failed: %d\n", req->service_name, ret); Timeout error log due to deadlock: " PDR: tms/servreg get domain list txn wait failed: -110 PDR: service lookup for msm/adsp/sensor_pd:tms/servreg failed: -110 " Thanks to Bjorn and Johan for letting me know that this commit also fixes an audio regression when using the in-kernel pd-mapper as that makes it easier to hit this race.

Commit e9f826b0459f ("soc: qcom: pmic_glink: simplify locking with guard()") was on top of a fix [1] which was moving the 'pg = __pmic_glink' assignment into the critical section. Unfortunately the actual fix was not applied and instead rebased version of the next patch got in. The resulting code is in general correct, but now there is a duplicated assignment 'pg = __pmic_glink'.

2025-01-06soc: qcom: socinfo: Avoid out of bounds read of serial numberStephan Gerhold
On MSM8916 devices, the serial number exposed in sysfs is constant and does not change across individual devices. It's always: db410c:/sys/devices/soc0$ cat serial_number 2644893864 The firmware used on MSM8916 exposes SOCINFO_VERSION(0, 8), which does not have support for the serial_num field in the socinfo struct. There is an existing check to avoid exposing the serial number in that case, but it's not correct: When checking the item_size returned by SMEM, we need to make sure the *end* of the serial_num is within bounds, instead of comparing with the *start* offset. The serial_number currently exposed on MSM8916 devices is just an out of bounds read of whatever comes after the socinfo struct in SMEM. Fix this by changing offsetof() to offsetofend(), so that the size of the field is also taken into account.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "The most significant set of changes is the per netns RTNL. The new behavior is disabled by default, regression risk should be contained. Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its default value from PTP_1588_CLOCK_KVM, as the first is intended to be a more reliable replacement for the latter. Core: - Started a very large, in-progress, effort to make the RTNL lock scope per network-namespace, thus reducing the lock contention significantly in the containerized use-case, comprising: - RCU-ified some relevant slices of the FIB control path - introduce basic per netns locking helpers - namespacified the IPv4 address hash table - remove rtnl_register{,_module}() in favour of rtnl_register_many() - refactor rtnl_{new,del,set}link() moving as much validation as possible out of RTNL lock - convert all phonet doit() and dumpit() handlers to RCU - convert IPv4 addresses manipulation to per-netns RTNL - convert virtual interface creation to per-netns RTNL the per-netns lock infrastructure is guarded by the CONFIG_DEBUG_NET_SMALL_RTNL knob, disabled by default ad interim. - Introduce NAPI suspension, to efficiently switching between busy polling (NAPI processing suspended) and normal processing. - Migrate the IPv4 routing input, output and control path from direct ToS usage to DSCP macros. This is a work in progress to make ECN handling consistent and reliable. - Add drop reasons support to the IPv4 rotue input path, allowing better introspection in case of packets drop. - Make FIB seqnum lockless, dropping RTNL protection for read access. - Make inet{,v6} addresses hashing less predicable. - Allow providing timestamp OPT_ID via cmsg, to correlate TX packets and timestamps Things we sprinkled into general kernel code: - Add small file operations for debugfs, to reduce the struct ops size. - Refactoring and optimization for the implementation of page_frag API, This is a preparatory work to consolidate the page_frag implementation. Netfilter: - Optimize set element transactions to reduce memory consumption - Extended netlink error reporting for attribute parser failure. - Make legacy xtables configs user selectable, giving users the option to configure iptables without enabling any other config. - Address a lot of false-positive RCU issues, pointed by recent CI improvements. BPF: - Put xsk sockets on a struct diet and add various cleanups. Overall, this helps to bump performance by 12% for some workloads. - Extend BPF selftests to increase coverage of XDP features in combination with BPF cpumap. - Optimize and homogenize bpf_csum_diff helper for all archs and also add a batch of new BPF selftests for it. - Extend netkit with an option to delegate skb->{mark,priority} scrubbing to its BPF program. - Make the bpf_get_netns_cookie() helper available also to tc(x) BPF programs. Protocols: - Introduces 4-tuple hash for connected udp sockets, speeding-up significantly connected sockets lookup. - Add a fastpath for some TCP timers that usually expires after close, the socket lock contention. - Add inbound and outbound xfrm state caches to speed up state lookups. - Avoid sending MPTCP advertisements on stale subflows, reducing risks on loosing them. - Make neighbours table flushing more scalable, maintaining per device neigh lists. Driver API: - Introduce a unified interface to configure transmission H/W shaping, and expose it to user-space via generic-netlink. - Add support for per-NAPI config via netlink. This makes napi configuration persistent across queues removal and re-creation. Requires driver updates, currently supported drivers are: nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice. - Add ethtool support for writing SFP / PHY firmware blocks. - Track RSS context allocation from ethtool core. - Implement support for mirroring to DSA CPU port, via TC mirror offload. - Consolidate FDB updates notification, to avoid duplicates on device-specific entries. - Expose DPLL clock quality level to the user-space. - Support master-slave PHY config via device tree. Tests and tooling: - forwarding: introduce deferred commands, to simplify the cleanup phase Drivers: - Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic, Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the IRQs and queues to NAPI IDs, allowing busy polling and better introspection. - Ethernet high-speed NICs: - nVidia/Mellanox: - mlx5: - a large refactor to implement support for cross E-Switch scheduling - refactor H/W conter management to let it scale better - H/W GRO cleanups - Intel (100G, ice):: - add support for ethtool reset - implement support for per TX queue H/W shaping - AMD/Solarflare: - implement per device queue stats support - Broadcom (bnxt): - improve wildcard l4proto on IPv4/IPv6 ntuple rules - Marvell Octeon: - Add representor support for each Resource Virtualization Unit (RVU) device. - Hisilicon: - add support for the BMC Gigabit Ethernet - IBM (EMAC): - driver cleanup and modernization - Cisco (VIC): - raise the queues number limit to 256 - Ethernet virtual: - Google vNIC: - implement page pool support - macsec: - inherit lower device's features and TSO limits when offloading - virtio_net: - enable premapped mode by default - support for XDP socket(AF_XDP) zerocopy TX - wireguard: - set the TSO max size to be GSO_MAX_SIZE, to aggregate larger packets. - Ethernet NICs embedded and virtual: - Broadcom ASP: - enable software timestamping - Freescale: - add enetc4 PF driver - MediaTek: Airoha SoC: - implement BQL support - RealTek r8169: - enable TSO by default on r8168/r8125 - implement extended ethtool stats - Renesas AVB: - enable TX checksum offload - Synopsys (stmmac): - support header splitting for vlan tagged packets - move common code for DWMAC4 and DWXGMAC into a separate FPE module. - add dwmac driver support for T-HEAD TH1520 SoC - Synopsys (xpcs): - driver refactor and cleanup - TI: - icssg_prueth: add VLAN offload support - Xilinx emaclite: - add clock support - Ethernet switches: - Microchip: - implement support for the lan969x Ethernet switch family - add LAN9646 switch support to KSZ DSA driver - Ethernet PHYs: - Marvel: 88q2x: enable auto negotiation - Microchip: add support for LAN865X Rev B1 and LAN867X Rev C1/C2 - PTP: - Add support for the Amazon virtual clock device - Add PtP driver for s390 clocks - WiFi: - mac80211 - EHT 1024 aggregation size for transmissions - new operation to indicate that a new interface is to be added - support radio separation of multi-band devices - move wireless extension spy implementation to libiw - Broadcom: - brcmfmac: optional LPO clock support - Microchip: - add support for Atmel WILC3000 - Qualcomm (ath12k): - firmware coredump collection support - add debugfs support for a multitude of statistics - Qualcomm (ath5k): - Arcadyan ARV45XX AR2417 & Gigaset SX76[23] AR241[34]A support - Realtek: - rtw88: 8821au and 8812au USB adapters support - rtw89: add thermal protection - rtw89: fine tune BT-coexsitence to improve user experience - rtw89: firmware secure boot for WiFi 6 chip - Bluetooth - add Qualcomm WCN785x support for ids Foxconn 0xe0fc/0xe0f3 and 0x13d3:0x3623 - add Realtek RTL8852BE support for id Foxconn 0xe123 - add MediaTek MT7920 support for wireless module ids - btintel_pcie: add handshake between driver and firmware - btintel_pcie: add recovery mechanism - btnxpuart: add GPIO support to power save feature" * tag 'net-next-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1475 commits) mm: page_frag: fix a compile error when kernel is not compiled Documentation: tipc: fix formatting issue in tipc.rst selftests: nic_performance: Add selftest for performance of NIC driver selftests: nic_link_layer: Add selftest case for speed and duplex states selftests: nic_link_layer: Add link layer selftest for NIC driver bnxt_en: Add FW trace coredump segments to the coredump bnxt_en: Add a new ethtool -W dump flag bnxt_en: Add 2 parameters to bnxt_fill_coredump_seg_hdr() bnxt_en: Add functions to copy host context memory bnxt_en: Do not free FW log context memory bnxt_en: Manage the FW trace context memory bnxt_en: Allocate backing store memory for FW trace logs bnxt_en: Add a 'force' parameter to bnxt_free_ctx_mem() bnxt_en: Refactor bnxt_free_ctx_mem() bnxt_en: Add mem_valid bit to struct bnxt_ctx_mem_type bnxt_en: Update firmware interface spec to 1.10.3.85 selftests/bpf: Add some tests with sockmap SK_PASS bpf: fix recursive lock when verdict program return SK_PASS wireguard: device: support big tcp GSO wireguard: selftests: load nf_conntrack if not present ...

Pull SoC devicetree updates from Arnd Bergmann: "This release adds the devicetree files for an impressive number of new SoC variants, though as expected these are all related to others we already support: - The microchip sam9x7 devicetree is now added, after the device driver and platform code has already made it in. This is likely the last ARMv5 (!) platform to ever get added, updating the 20+ year old at91/sam9 platform with DDR3 memory and gigabit ethernet. - On the Apple platform, there are now devicetree files for a number of A-series SoCs in addition to the M-series ones, these are used primarily in phones and tablets, but are closely related to the already supported chips. - Samsung Exynos 8895 and Exynos 990 are more phone SoCs used in older Samsung Galaxy phones. - Qualcomm Snapdragon 778G (SM7325) is another phone SoC, closely related to the Snapdragon 7c+ Gen 3 (SC7280) used in low-end laptops. - Rockchip RK3528 and RK3576 are new variants of their TV box and Tablet chips, still using the older ARMv8.0 cores from RK3328/RK3399 but with a newer process and other improvements from the RK35xx (otherwise ARMv8.2) chips. RK3566T and RK3399-S are also added, these are just lower-cost versions of their normal counterparts. - TI J742S2 is a feature-reduced version of the J784s4 industrial/automotive SoC, with fewer CPU cores. - Sophgo SG2002 is an embedded SoC with one RISC-V (C906) and one ARM (Cortex-A53) core, at this point support is only added for running on the RISC-V side on the LicheeRV Nano board. A total of 92 new .dts files describing individual machines is added, which must be a new record. The majority of these is for the newly added chips above, notably all the Apple phones and tablets. The other new machines include nine industrial/embedded boards with NXP i.MX6 or i.MX8 SoCs, eight for Rockchips RK35XX and one or two each for Rockchips RV1109, RK3308, Allwinner A33, Tegra 234, Qualcomm qcs9100/sc8280xp/x1e80100, TI AM625 and Starfive JH7110.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull interrupt subsystem updates from Thomas Gleixner: "Tree wide: - Make nr_irqs static to the core code and provide accessor functions to remove existing and prevent future aliasing problems with local variables or function arguments of the same name. Core code: - Prevent freeing an interrupt in the devres code which is not managed by devres in the first place. - Use seq_put_decimal_ull_width() for decimal values output in /proc/interrupts which increases performance significantly as it avoids parsing the format strings over and over. - Optimize raising the timer and hrtimer soft interrupts by using the 'set bit only' variants instead of the combined version which checks whether ksoftirqd should be woken up. The latter is a pointless exercise as both soft interrupts are raised in the context of the timer interrupt and therefore never wake up ksoftirqd. - Delegate timer/hrtimer soft interrupt processing to a dedicated thread on RT. Timer and hrtimer soft interrupts are always processed in ksoftirqd on RT enabled kernels. This can lead to high latencies when other soft interrupts are delegated to ksoftirqd as well. The separate thread allows to run them seperately under a RT scheduling policy to reduce the latency overhead. Drivers: - New drivers or extensions of existing drivers to support Renesas RZ/V2H(P), Aspeed AST27XX, T-HEAD C900 and ATMEL sam9x7 interrupt chips - Support for multi-cluster GICs on MIPS. MIPS CPUs can come with multiple CPU clusters, where each CPU cluster has its own GIC (Generic Interrupt Controller). This requires to access the GIC of a remote cluster through a redirect register block. This is encapsulated into a set of helper functions to keep the complexity out of the actual code paths which handle the GIC details. - Support for encrypted guests in the ARM GICV3 ITS driver The ITS page needs to be shared with the hypervisor and therefore must be decrypted. - Small cleanups and fixes all over the place" * tag 'irq-core-2024-11-18' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (50 commits) irqchip/riscv-aplic: Prevent crash when MSI domain is missing genirq/proc: Use seq_put_decimal_ull_width() for decimal values softirq: Use a dedicated thread for timer wakeups on PREEMPT_RT. timers: Use __raise_softirq_irqoff() to raise the softirq. hrtimer: Use __raise_softirq_irqoff() to raise the softirq riscv: defconfig: Enable T-HEAD C900 ACLINT SSWI drivers irqchip: Add T-HEAD C900 ACLINT SSWI driver dt-bindings: interrupt-controller: Add T-HEAD C900 ACLINT SSWI device irqchip/stm32mp-exti: Use of_property_present() for non-boolean properties irqchip/mips-gic: Fix selection of GENERIC_IRQ_EFFECTIVE_AFF_MASK irqchip/mips-gic: Prevent indirect access to clusters without CPU cores irqchip/mips-gic: Multi-cluster support irqchip/mips-gic: Setup defaults in each cluster irqchip/mips-gic: Support multi-cluster in for_each_online_cpu_gic() irqchip/mips-gic: Replace open coded online CPU iterations genirq/irqdesc: Use str_enabled_disabled() helper in wakeup_show() genirq/devres: Don't free interrupt which is not managed by devres irqchip/gic-v3-its: Fix over allocation in itt_alloc_pool() irqchip/aspeed-intc: Add AST27XX INTC support dt-bindings: interrupt-controller: Add support for ASPEED AST27XX INTC ...

2024-11-14soc: fsl: cpm1: qmc: Set the ret error code on platform_get_irq() failureHerve Codina
A kernel test robot detected a missing error code: qmc.c:1942 qmc_probe() warn: missing error code 'ret' Indeed, the error returned by platform_get_irq() is checked and the operation is aborted in case of failure but the ret error code is not set in that case. Set the ret error code.

2024-11-14soc: fsl: rcpm: fix missing of_node_put() in copy_ippdexpcr1_setting()Javier Carrasco
of_find_compatible_node() requires a call to of_node_put() when the pointer to the node is not required anymore to decrement its refcount and avoid leaking memory. Add the missing call to of_node_put() after the node has been used.

The non-scoped variant of this macro turns error-prone as soon as error paths are included, because explicit calls to of_node_put() are required to avoid leaking memory. Using its scoped counterpart simplifies the code by removing the need of explicit calls to of_node_put(), as they are automatically triggered as soon as the child node goes out of scope. Moreover, it is more robust as it accounts for new error paths without having to worry about decrementing the object's refcount. Note that the device_node is declared within the macro, and its explicit declaration can be dropped as well if it is not used anywhere else.
