git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "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.

2022-10-04ethtool: add interface to interact with Ethernet Power EquipmentOleksij Rempel1-0/+58
Add interface to support Power Sourcing Equipment. At current step it provides generic way to address all variants of PSE devices as defined in IEEE 802.3-2018 but support only objects specified for IEEE 802.3-2018 104.4 PoDL Power Sourcing Equipment (PSE). Currently supported and mandatory objects are: IEEE 802.3-2018 30.15.1.1.3 aPoDLPSEPowerDetectionStatus IEEE 802.3-2018 30.15.1.1.2 aPoDLPSEAdminState IEEE 802.3-2018 30.15.1.2.1 acPoDLPSEAdminControl This is minimal interface needed to control PSE on each separate ethernet port but it provides not all mandatory objects specified in IEEE 802.3-2018. Since "PoDL PSE" and "PSE" have similar names, but some different values I decide to not merge them and keep separate naming schema. This should allow as to be as close to IEEE 802.3 spec as possible and avoid name conflicts in the future. This implementation is connected to PHYs instead of MACs because PSE auto classification can potentially interfere with PHY auto negotiation. So, may be some extra PHY related initialization will be needed.

git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull kernel hardening updates from Kees Cook: "Most of the collected changes here are fixes across the tree for various hardening features (details noted below). The most notable new feature here is the addition of the memcpy() overflow warning (under CONFIG_FORTIFY_SOURCE), which is the next step on the path to killing the common class of "trivially detectable" buffer overflow conditions (i.e. on arrays with sizes known at compile time) that have resulted in many exploitable vulnerabilities over the years (e.g. BleedingTooth). This feature is expected to still have some undiscovered false positives. It's been in -next for a full development cycle and all the reported false positives have been fixed in their respective trees. All the known-bad code patterns we could find with Coccinelle are also either fixed in their respective trees or in flight. The commit message in commit 54d9469bc515 ("fortify: Add run-time WARN for cross-field memcpy()") for the feature has extensive details, but I'll repeat here that this is a warning _only_, and is not intended to actually block overflows (yet). The many patches fixing array sizes and struct members have been landing for several years now, and we're finally able to turn this on to find any remaining stragglers. Summary: Various fixes across several hardening areas: - loadpin: Fix verity target enforcement (Matthias Kaehlcke). - zero-call-used-regs: Add missing clobbers in paravirt (Bill Wendling). - CFI: clean up sparc function pointer type mismatches (Bart Van Assche). - Clang: Adjust compiler flag detection for various Clang changes (Sami Tolvanen, Kees Cook). - fortify: Fix warnings in arch-specific code in sh, ARM, and xen. Improvements to existing features: - testing: improve overflow KUnit test, introduce fortify KUnit test, add more coverage to LKDTM tests (Bart Van Assche, Kees Cook). - overflow: Relax overflow type checking for wider utility. New features: - string: Introduce strtomem() and strtomem_pad() to fill a gap in strncpy() replacement needs. - um: Enable FORTIFY_SOURCE support. - fortify: Enable run-time struct member memcpy() overflow warning" * tag 'hardening-v6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: (27 commits) Makefile.extrawarn: Move -Wcast-function-type-strict to W=1 hardening: Remove Clang's enable flag for -ftrivial-auto-var-init=zero sparc: Unbreak the build x86/paravirt: add extra clobbers with ZERO_CALL_USED_REGS enabled x86/paravirt: clean up typos and grammaros fortify: Convert to struct vs member helpers fortify: Explicitly check bounds are compile-time constants x86/entry: Work around Clang __bdos() bug ARM: decompressor: Include .data.rel.ro.local fortify: Adjust KUnit test for modular build sh: machvec: Use char[] for section boundaries kunit/memcpy: Avoid pathological compile-time string size lib: Improve the is_signed_type() kunit test LoadPin: Require file with verity root digests to have a header dm: verity-loadpin: Only trust verity targets with enforcement LoadPin: Fix Kconfig doc about format of file with verity digests um: Enable FORTIFY_SOURCE lkdtm: Update tests for memcpy() run-time warnings fortify: Add run-time WARN for cross-field memcpy() fortify: Use SIZE_MAX instead of (size_t)-1 ...

git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull kcfi updates from Kees Cook: "This replaces the prior support for Clang's standard Control Flow Integrity (CFI) instrumentation, which has required a lot of special conditions (e.g. LTO) and work-arounds.

2022-10-04net/mlx5e: xsk: Optimize for unaligned mode with 3072-byte framesMaxim Mikityanskiy4-3/+61
When XSK frame size is 3072 (or another power of two multiplied by 3), KLM mechanism for NIC virtual memory page mapping can be optimized by replacing it with KSM. Before this change, two KLM entries were needed to map an XSK frame that is not a power of two: one entry maps the UMEM memory up to the frame length, the other maps the rest of the stride to the garbage page. When the frame length divided by 3 is a power of two, it can be mapped using 3 KSM entries, and the fourth will map the rest of the stride to the garbage page. All 4 KSM entries are of the same size, which allows for a much faster lookup. Frame size 3072 is useful in certain use cases, because it allows packing 4 frames into 3 pages. Generally speaking, other frame sizes equal to PAGE_SIZE minus a power of two can be optimized in a similar way, but it will require many more KSMs per frame, which slows down UMRs a little bit, but more importantly may hit the limit for the maximum number of KSM entries.

2022-10-04net/mlx5e: xsk: Print a warning in slow configurationsMaxim Mikityanskiy1-0/+9
On striding RQ, when the XSK frame size doesn't match the MKey page size, KLM is used for memory mappings, which is a slower mechanism than MTT or KSM. It may happen in two cases: 1. Frame size is not a power of two (only possible in the unaligned mode of XSK). 2. Frame size is 2048 bytes, and the firmware doesn't support MKey pages smaller than 4096 bytes. Depending on the case, print a warning and recommend to disable striding RQ or upgrade the firmware.

2022-10-04net/mlx5e: xsk: Use KLM to protect frame overrun in unaligned modeMaxim Mikityanskiy4-10/+90
XSK RQs support striding RQ linear mode, but the stride size may be bigger than the XSK frame size, because: 1. The stride size must be a power of two. 2. The stride size must be equal to the UMR page size. Each XSK frame is treated as a separate page, because they aren't necessarily adjacent in physical memory, so the driver can't put more than one stride per page. 3. The minimal MTT page size is 4096 on older firmware. That means that if XSK frame size is 2048 or not a power of two, the strides may be bigger than XSK frames. Normally, it's not a problem if the hardware enforces the MTU. However, traffic between vports skips the hardware MTU check, and oversized packets may be received. If an oversized packet is bigger than the XSK frame but not bigger than the stride, it will cause overwriting of the adjacent UMEM region. If the packet takes more than one stride, they can be recycled for reuse, so it's not a problem when the XSK frame size matches the stride size. Work around the above issue by leveraging KLM to make a more fine-grained mapping. The beginning of each stride is mapped to the frame memory, and the padding up to the closest power of two is mapped to the overflow page that doesn't belong to UMEM. This way, application data corruption won't happen upon receiving packets bigger than MTU.

XSK need_wakeup mechanism allows the driver to stop busy waiting for buffers when the fill ring is empty, yield to the application and signal it that the driver needs to be waken up after the application refills the fill ring. Add protection against the race condition on the RX (refill) side: if the application refills buffers after xskrq->post_wqes is called, but before mlx5e_xsk_update_rx_wakeup, NAPI will exit, skipping taking these buffers to the hardware WQ, and the application won't wake it up again.

2022-10-04net: mvpp2: fix mvpp2 debugfs leakRussell King (Oracle)3-3/+21
When mvpp2 is unloaded, the driver specific debugfs directory is not removed, which technically leads to a memory leak. However, this directory is only created when the first device is probed, so the hardware is present. Removing the module is only something a developer would to when e.g. testing out changes, so the module would be reloaded. So this memory leak is minor. The original attempt in commit fe2c9c61f668 ("net: mvpp2: debugfs: fix memory leak when using debugfs_lookup()") that was labelled as a memory leak fix was not, it fixed a refcount leak, but in doing so created a problem when the module is reloaded - the directory already exists, but mvpp2_root is NULL, so we lose all debugfs entries. This fix has been reverted. This is the alternative fix, where we remove the offending directory whenever the driver is unloaded.
