The main driver for this has been the introduction of the LoonArch architecture last cycle, which inspired some cleanup and refactoring of the EFI code. Another driver for EFI changes this cycle and in the future is confidential compute. The LoongArch architecture does not use either struct bootparams or DT natively [yet], and so passing information between the EFI stub and the core kernel using either of those is undesirable. And in general, overloading DT has been a source of issues on arm64, so using DT for this on new architectures is a to avoid for the time being (even if we might converge on something DT based for non-x86 architectures in the future). For this reason, in addition to the patch that enables EFI boot for LoongArch, there are a number of refactoring patches applied on top of which separate the DT bits from the generic EFI stub bits. These changes are on a separate topich branch that has been shared with the LoongArch maintainers, who will include it in their pull request as well. This is not ideal, but the best way to manage the conflicts without stalling LoongArch for another cycle. Another development inspired by LoongArch is the newly added support for EFI based decompressors. Instead of adding yet another arch-specific incarnation of this pattern for LoongArch, we are introducing an EFI app based on the existing EFI libstub infrastructure that encapulates the decompression code we use on other architectures, but in a way that is fully generic. This has been developed and tested in collaboration with distro and systemd folks, who are eager to start using this for systemd-boot and also for arm64 secure boot on Fedora. Note that the EFI zimage files this introduces can also be decompressed by non-EFI bootloaders if needed, as the image header describes the location of the payload inside the image, and the type of compression that was used. (Note that Fedora's arm64 GRUB is buggy [0] so you'll need a recent version or switch to systemd-boot in order to use this.) Finally, we are adding TPM measurement of the kernel command line provided by EFI. There is an oversight in the TCG spec which results in a blind spot for command line arguments passed to loaded images, which means that either the loader or the stub needs to take the measurement. Given the combinatorial explosion I am anticipating when it comes to firmware/bootloader stacks and firmware based attestation protocols (SEV-SNP, TDX, DICE, DRTM), it is good to set a baseline now when it comes to EFI measured boot, which is that the kernel measures the initrd and command line. Intermediate loaders can measure additional assets if needed, but with the baseline in place, we can deploy measured boot in a meaningful way even if you boot into Linux straight from the EFI firmware. Summary: - implement EFI boot support for LoongArch - implement generic EFI compressed boot support for arm64, RISC-V and LoongArch, none of which implement a decompressor today - measure the kernel command line into the TPM if measured boot is in effect - refactor the EFI stub code in order to isolate DT dependencies for architectures other than x86 - avoid calling SetVirtualAddressMap() on arm64 if the configured size of the VA space guarantees that doing so is unnecessary - move some ARM specific code out of the generic EFI source files - unmap kernel code from the x86 mixed mode 1:1 page tables" * tag 'efi-next-for-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi: (24 commits) efi/arm64: libstub: avoid SetVirtualAddressMap() when possible efi: zboot: create MemoryMapped() device path for the parent if needed efi: libstub: fix up the last remaining open coded boot service call efi/arm: libstub: move ARM specific code out of generic routines efi/libstub: measure EFI LoadOptions efi/libstub: refactor the initrd measuring functions efi/loongarch: libstub: remove dependency on flattened DT efi: libstub: install boot-time memory map as config table efi: libstub: remove DT dependency from generic stub efi: libstub: unify initrd loading between architectures efi: libstub: remove pointless goto kludge efi: libstub: simplify efi_get_memory_map() and struct efi_boot_memmap efi: libstub: avoid efi_get_memory_map() for allocating the virt map efi: libstub: drop pointless get_memory_map() call efi: libstub: fix type confusion for load_options_size arm64: efi: enable generic EFI compressed boot loongarch: efi: enable generic EFI compressed boot riscv: efi: enable generic EFI compressed boot efi/libstub: implement generic EFI zboot efi/libstub: move efi_system_table global var into separate object ...	2022-10-09 08:56:54 -07:00

Linus Torvalds	0326074ff4	Networking changes for 6.1. ... Core ---- - Introduce and use a single page frag cache for allocating small skb heads, clawing back the 10-20% performance regression in UDP flood test from previous fixes. - Run packets which already went thru HW coalescing thru SW GRO. This significantly improves TCP segment coalescing and simplifies deployments as different workloads benefit from HW or SW GRO. - Shrink the size of the base zero-copy send structure. - Move TCP init under a new slow / sleepable version of DO_ONCE(). BPF --- - Add BPF-specific, any-context-safe memory allocator. - Add helpers/kfuncs for PKCS#7 signature verification from BPF programs. - Define a new map type and related helpers for user space -> kernel communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF). - Allow targeting BPF iterators to loop through resources of one task/thread. - Add ability to call selected destructive functions. Expose crash_kexec() to allow BPF to trigger a kernel dump. Use CAP_SYS_BOOT check on the loading process to judge permissions. - Enable BPF to collect custom hierarchical cgroup stats efficiently by integrating with the rstat framework. - Support struct arguments for trampoline based programs. Only structs with size <= 16B and x86 are supported. - Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping sockets (instead of just TCP and UDP sockets). - Add a helper for accessing CLOCK_TAI for time sensitive network related programs. - Support accessing network tunnel metadata's flags. - Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open. - Add support for writing to Netfilter's nf_conn:mark. Protocols --------- - WiFi: more Extremely High Throughput (EHT) and Multi-Link Operation (MLO) work (802.11be, WiFi 7). - vsock: improve support for SO_RCVLOWAT. - SMC: support SO_REUSEPORT. - Netlink: define and document how to use netlink in a "modern" way. Support reporting missing attributes via extended ACK. - IPSec: support collect metadata mode for xfrm interfaces. - TCPv6: send consistent autoflowlabel in SYN_RECV state and RST packets. - TCP: introduce optional per-netns connection hash table to allow better isolation between namespaces (opt-in, at the cost of memory and cache pressure). - MPTCP: support TCP_FASTOPEN_CONNECT. - Add NEXT-C-SID support in Segment Routing (SRv6) End behavior. - Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets. - Open vSwitch: - Allow specifying ifindex of new interfaces. - Allow conntrack and metering in non-initial user namespace. - TLS: support the Korean ARIA-GCM crypto algorithm. - Remove DECnet support. Driver API ---------- - Allow selecting the conduit interface used by each port in DSA switches, at runtime. - Ethernet Power Sourcing Equipment and Power Device support. - Add tc-taprio support for queueMaxSDU parameter, i.e. setting per traffic class max frame size for time-based packet schedules. - Support PHY rate matching - adapting between differing host-side and link-side speeds. - Introduce QUSGMII PHY mode and 1000BASE-KX interface mode. - Validate OF (device tree) nodes for DSA shared ports; make phylink-related properties mandatory on DSA and CPU ports. Enforcing more uniformity should allow transitioning to phylink. - Require that flash component name used during update matches one of the components for which version is reported by info_get(). - Remove "weight" argument from driver-facing NAPI API as much as possible. It's one of those magic knobs which seemed like a good idea at the time but is too indirect to use in practice. - Support offload of TLS connections with 256 bit keys.

Ard Biesheuvel	d3549a938b	efi/arm64: libstub: avoid SetVirtualAddressMap() when possible ... EFI's SetVirtualAddressMap() runtime service is a horrid hack that we'd like to avoid using, if possible. For 64-bit architectures such as arm64, the user and kernel mappings are entirely disjoint, and given that we use the user region for mapping the UEFI runtime regions when running under the OS, we don't rely on SetVirtualAddressMap() in the conventional way, i.e., to permit kernel mappings of the OS to coexist with kernel region mappings of the firmware regions. This means that, in principle, we should be able to avoid SetVirtualAddressMap() altogether, and simply use the 1:1 mapping that UEFI uses at boot time. (Note that omitting SetVirtualAddressMap() is explicitly permitted by the UEFI spec). However, there is a corner case on arm64, which, if configured for 3-level paging (or 2-level paging when using 64k pages), may not be able to cover the entire range of firmware mappings (which might contain both memory and MMIO peripheral mappings). So let's avoid SetVirtualAddressMap() on arm64, but only if the VA space is guaranteed to be of sufficient size. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>	2022-09-27 13:26:16 +02:00

The reference implementation even does this (with a NULL protocol pointer) if the call to LoadImage() used the source buffer and size arguments, and passed NULL for the image device path. Hand rolled implementations of LoadImage may behave differently, though, and so it is better to tolerate situations where the protocol is missing. And actually, concatenating an Offset() node to a NULL device path (as we do currently) is not great either. So in cases where the protocol is absent, or when it points to NULL, construct a MemoryMapped() device node as the base node that describes the parent image's footprint in memory.

Ilias Apalodimas	71c7adc9ff	efi/libstub: measure EFI LoadOptions ... The EFI TCG spec, in §10.2.6 "Measuring UEFI Variables and UEFI GPT Data", only reasons about the load options passed to a loaded image in the context of boot options booted directly from the BDS, which are measured into PCR #5 along with the rest of the Boot#### EFI variable. However, the UEFI spec mentions the following in the documentation of the LoadImage() boot service and the EFI_LOADED_IMAGE protocol: The caller may fill in the image’s "load options" data, or add additional protocol support to the handle before passing control to the newly loaded image by calling EFI_BOOT_SERVICES.StartImage(). The typical boot sequence for Linux EFI systems is to load GRUB via a boot option from the BDS, which [hopefully] calls LoadImage to load the kernel image, passing the kernel command line via the mechanism described above. This means that we cannot rely on the firmware implementing TCG measured boot to ensure that the kernel command line gets measured before the image is started, so the EFI stub will have to take care of this itself. Given that PCR #5 has an official use in the TCG measured boot spec, let's avoid it in this case. Instead, add a measurement in PCR #9 (which we already use for our initrd) and extend it with the LoadOptions measurements Co-developed-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: Ard Biesheuvel <ardb@kernel.org>	2022-09-27 13:26:16 +02:00
Ilias Apalodimas	5663316963	efi/libstub: refactor the initrd measuring functions ... Currently, from the efi-stub, we are only measuring the loaded initrd, using the TCG2 measured boot protocols. A following patch is introducing measurements of additional components, such as the kernel command line. On top of that, we will shortly have to support other types of measured boot that don't expose the TCG2 protocols. So let's prepare for that, by rejigging the efi_measure_initrd() routine into something that we should be able to reuse for measuring other assets, and which can be extended later to support other measured boot protocols.

Ard Biesheuvel	40cd01a9c3	efi/loongarch: libstub: remove dependency on flattened DT ... LoongArch does not use FDT or DT natively [yet], and the only reason it currently uses it is so that it can reuse the existing EFI stub code. Overloading the DT with data passed between the EFI stub and the core kernel has been a source of problems: there is the overlap between information provided by EFI which DT can also provide (initrd base/size, command line, memory descriptions), requiring us to reason about which is which and what to prioritize. It has also resulted in ABI leaks, i.e., internal ABI being promoted to external ABI inadvertently because the bootloader can set the EFI stub's DT properties as well (e.g., "kaslr-seed"). This has become especially problematic with boot environments that want to pretend that EFI boot is being done (to access ACPI and SMBIOS tables, for instance) but have no ability to execute the EFI stub, and so the environment that the EFI stub creates is emulated [poorly, in some cases]. Another downside of treating DT like this is that the DT binary that the kernel receives is different from the one created by the firmware, which is undesirable in the context of secure and measured boot. Given that LoongArch support in Linux is brand new, we can avoid these pitfalls, and treat the DT strictly as a hardware description, and use a separate handover method between the EFI stub and the kernel. Now that initrd loading and passing the EFI memory map have been refactored into pure EFI routines that use EFI configuration tables, the only thing we need to pass directly is the kernel command line (even if we could pass this via a config table as well, it is used extremely early, so passing it directly is preferred in this case.)

Liam R. Howlett	d4af56c5c7	mm: start tracking VMAs with maple tree ... Start tracking the VMAs with the new maple tree structure in parallel with the rb_tree. Add debug and trace events for maple tree operations and duplicate the rb_tree that is created on forks into the maple tree. The maple tree is added to the mm_struct including the mm_init struct, added support in required mm/mmap functions, added tracking in kernel/fork for process forking, and used to find the unmapped_area and checked against what the rbtree finds. This also moves the mmap_lock() in exit_mmap() since the oom reaper call does walk the VMAs. Otherwise lockdep will be unhappy if oom happens. When splitting a vma fails due to allocations of the maple tree nodes, the error path in __split_vma() calls new->vm_ops->close(new). The page accounting for hugetlb is actually in the close() operation, so it accounts for the removal of 1/2 of the VMA which was not adjusted. This results in a negative exit value. To avoid the negative charge, set vm_start = vm_end and vm_pgoff = 0. There is also a potential accounting issue in special mappings from insert_vm_struct() failing to allocate, so reverse the charge there in the failure scenario.

However, efi_get_memory_map() has grown some additional complexity over the years, and today, we're actually better off calling the EFI boot service directly with a zero size, which tells us how much memory should be enough for the virt map.

With that said, taking a spinlock in this scenario is a dangerous invitation for lockup scenarios.

Otherwise it is pointless to even attempt to verify its checksum. Also fix the maximum length check, which is technically 32, not 31. It does not matter in practice as the only valid values are 31 (for SMBIOS 2.x) and 24 (for SMBIOS 3.x), but let's still have the check right in case new fields are added to either structure in the future.

Ulf Hansson	3c66563378	Revert "firmware: arm_scmi: Add clock management to the SCMI power domain" ... This reverts commit a3b884cef8 ("firmware: arm_scmi: Add clock management to the SCMI power domain"). Using the GENPD_FLAG_PM_CLK tells genpd to gate/ungate the consumer device's clock(s) during runtime suspend/resume through the PM clock API. More precisely, in genpd_runtime_resume() the clock(s) for the consumer device would become ungated prior to the driver-level ->runtime_resume() callbacks gets invoked. This behaviour isn't a good fit for all platforms/drivers. For example, a driver may need to make some preparations of its device in its ->runtime_resume() callback, like calling clk_set_rate() before the clock(s) should be ungated. In these cases, it's easier to let the clock(s) to be managed solely by the driver, rather than at the PM domain level. For these reasons, let's drop the use GENPD_FLAG_PM_CLK for the SCMI PM domain, as to enable it to be more easily adopted across ARM platforms.

Ard Biesheuvel	5f56a74cc0	efi: libstub: check Shim mode using MokSBStateRT ... We currently check the MokSBState variable to decide whether we should treat UEFI secure boot as being disabled, even if the firmware thinks otherwise. This is used by shim to indicate that it is not checking signatures on boot images. In the kernel, we use this to relax lockdown policies. However, in cases where shim is not even being used, we don't want this variable to interfere with lockdown, given that the variable may be non-volatile and therefore persist across a reboot. This means setting it once will persistently disable lockdown checks on a given system. So switch to the mirrored version of this variable, called MokSBStateRT, which is supposed to be volatile, and this is something we can check.

Ard Biesheuvel	63bf28ceb3	efi: x86: Wipe setup_data on pure EFI boot ... When booting the x86 kernel via EFI using the LoadImage/StartImage boot services [as opposed to the deprecated EFI handover protocol], the setup header is taken from the image directly, and given that EFI's LoadImage has no Linux/x86 specific knowledge regarding struct bootparams or struct setup_header, any absolute addresses in the setup header must originate from the file and not from a prior loading stage. Since we cannot generally predict where LoadImage() decides to load an image (*), such absolute addresses must be treated as suspect: even if a prior boot stage intended to make them point somewhere inside the [signed] image, there is no way to validate that, and if they point at an arbitrary location in memory, the setup_data nodes will not be covered by any signatures or TPM measurements either, and could be made to contain an arbitrary sequence of SETUP_xxx nodes, which could interfere quite badly with the early x86 boot sequence. (*) Note that, while LoadImage() does take a buffer/size tuple in addition to a device path, which can be used to provide the image contents directly, it will re-allocate such images, as the memory footprint of an image is generally larger than the PE/COFF file representation.

Ard Biesheuvel	a050910972	efi/libstub: implement generic EFI zboot ... Implement a minimal EFI app that decompresses the real kernel image and launches it using the firmware's LoadImage and StartImage boot services. This removes the need for any arch-specific hacks. Note that on systems that have UEFI secure boot policies enabled, LoadImage/StartImage require images to be signed, or their hashes known a priori, in order to be permitted to boot. There are various possible strategies to work around this requirement, but they all rely either on overriding internal PI/DXE protocols (which are not part of the EFI spec) or omitting the firmware provided LoadImage() and StartImage() boot services, which is also undesirable, given that they encapsulate platform specific policies related to secure boot and measured boot, but also related to memory permissions (whether or not and which types of heap allocations have both write and execute permissions.) The only generic and truly portable way around this is to simply sign both the inner and the outer image with the same key/cert pair, so this is what is implemented here.
