2023-10-10iommu: Add new iommu op to create domains owned by userspaceYi Liu
Introduce a new iommu_domain op to create domains owned by userspace, e.g. through IOMMUFD. These domains have a few different properties compares to kernel owned domains: - They may be PAGING domains, but created with special parameters. For instance aperture size changes/number of levels, different IOPTE formats, or other things necessary to make a vIOMMU work - We have to track all the memory allocations with GFP_KERNEL_ACCOUNT to make the cgroup sandbox stronger - Device-specialty domains, such as NESTED domains can be created by IOMMUFD. The new op clearly says the domain is being created by IOMMUFD, that the domain is intended for userspace use, and it provides a way to pass user flags or a driver specific uAPI structure to customize the created domain to exactly what the vIOMMU userspace driver requires. iommu drivers that cannot support VFIO/IOMMUFD should not support this op. This includes any driver that cannot provide a fully functional PAGING domain. This new op for now is only supposed to be used by IOMMUFD, hence no wrapper for it. IOMMUFD would call the callback directly. As for domain free, IOMMUFD would use iommu_domain_free().

2023-10-10serial: add PORT_GENERIC definitionMax Filippov
Current pattern in the linux kernel is that every new serial driver adds one or more new PORT_ definitions because uart_ops::config_port() callback documentation prescribes setting port->type according to the type of port found, or to PORT_UNKNOWN if no port was detected. When the specific type of the port is not important to the userspace there's no need for a unique PORT_ value, but so far there's no suitable identifier for that case. Provide generic port type identifier other than PORT_UNKNOWN for ports which type is not important to userspace.

2023-10-09bpf: Derive source IP addr via bpf_*_fib_lookup()Martynas Pumputis
Extend the bpf_fib_lookup() helper by making it to return the source IPv4/IPv6 address if the BPF_FIB_LOOKUP_SRC flag is set. For example, the following snippet can be used to derive the desired source IP address: struct bpf_fib_lookup p = { .ipv4_dst = ip4->daddr }; ret = bpf_skb_fib_lookup(skb, p, sizeof(p), BPF_FIB_LOOKUP_SRC | BPF_FIB_LOOKUP_SKIP_NEIGH); if (ret != BPF_FIB_LKUP_RET_SUCCESS) return TC_ACT_SHOT; /* the p.ipv4_src now contains the source address */ The inability to derive the proper source address may cause malfunctions in BPF-based dataplanes for hosts containing netdevs with more than one routable IP address or for multi-homed hosts. For example, Cilium implements packet masquerading in BPF. If an egressing netdev to which the Cilium's BPF prog is attached has multiple IP addresses, then only one [hardcoded] IP address can be used for masquerading. This breaks connectivity if any other IP address should have been selected instead, for example, when a public and private addresses are attached to the same egress interface. The change was tested with Cilium [1]. Nikolay Aleksandrov helped to figure out the IPv6 addr selection.

Provide the generic sync_try_cmpxchg() function from the raw_ prefixed version, also adding explicit instrumentation. The patch amends existing scripts to generate sync_try_cmpxchg() locking primitive and its raw_sync_try_cmpxchg() fallback, while leaving existing macros from the try_cmpxchg() family unchanged. The target can define its own arch_sync_try_cmpxchg() to override the generic version of raw_sync_try_cmpxchg(). This allows the target to generate more optimal assembly than the generic version.

2023-10-09bpf: Add ability to pin bpf timer to calling CPUDavid Vernet
BPF supports creating high resolution timers using bpf_timer_* helper functions. Currently, only the BPF_F_TIMER_ABS flag is supported, which specifies that the timeout should be interpreted as absolute time. It would also be useful to be able to pin that timer to a core. For example, if you wanted to make a subset of cores run without timer interrupts, and only have the timer be invoked on a single core. This patch adds support for this with a new BPF_F_TIMER_CPU_PIN flag. When specified, the HRTIMER_MODE_PINNED flag is passed to hrtimer_start(). A subsequent patch will update selftests to validate.

2023-10-09drm/bridge: samsung-dsim: update PLL reference clockMichael Tretter
The PLL requires a clock frequency in a certain platform-dependent range after the pre-divider. The reference clock for the PLL may change due to changes to it's parent clock. Thus, the frequency may be out of range or unsuited for generating the high speed clock for MIPI DSI. Try to keep the pre-devider small, and set the reference clock close to the upper limit before recalculating the PLL configuration. Use a divider with a power of two for the reference clock as this seems to work best in my tests.

2023-10-09drm/bridge: samsung-dsim: reread ref clock before configuring PLLMichael Tretter
The PLL reference clock may change at runtime when its parent clock changes. For example, this may happen on the i.MX8M Nano if the reference clock is a child of the Video PLL. If the pixel clock changes, this may propagate to the Video PLL and as a side effect change the reference clock. Thus, reading the clock rate during probe is not sufficient to correctly configure the PLL for the expected hs clock. Read the actual rate of the reference clock before calculating the PLL configuration parameters. Note that the "samsung,pll-clock-frequency" is always preferred and PLL reference clock is only read from the clock tree if that device tree property is not set.

2023-10-09string.h: add array-wrappers for (v)memdup_user()Philipp Stanner
Currently, user array duplications are sometimes done without an overflow check. Sometimes the checks are done manually; sometimes the array size is calculated with array_size() and sometimes by calculating n * size directly in code. Introduce wrappers for arrays for memdup_user() and vmemdup_user() to provide a standardized and safe way for duplicating user arrays. This is both for new code as well as replacing usage of (v)memdup_user() in existing code that uses, e.g., n * size to calculate array sizes.

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct kvm_irq_routing_table.
