VFIO updates for v6.6-rc1
- VFIO direct character device (cdev) interface support. This extracts the vfio device fd from the container and group model, and is intended to be the native uAPI for use with IOMMUFD. (Yi Liu) - Enhancements to the PCI hot reset interface in support of cdev usage. (Yi Liu) - Fix a potential race between registering and unregistering vfio files in the kvm-vfio interface and extend use of a lock to avoid extra drop and acquires. (Dmitry Torokhov) - A new vfio-pci variant driver for the AMD/Pensando Distributed Services Card (PDS) Ethernet device, supporting live migration. (Brett Creeley) - Cleanups to remove redundant owner setup in cdx and fsl bus drivers, and simplify driver init/exit in fsl code. (Li Zetao) - Fix uninitialized hole in data structure and pad capability structures for alignment.

Modules changes for v6.6-rc1
Summary of the changes worth highlighting from most interesting to boring below: * Christoph Hellwig's symbol_get() fix to Nvidia's efforts to circumvent the protection he put in place in year 2020 to prevent proprietary modules from using GPL only symbols, and also ensuring proprietary modules which export symbols grandfather their taint. That was done through year 2020 commit |

Networking changes for 6.6.
Core ---- - Increase size limits for to-be-sent skb frag allocations. This allows tun, tap devices and packet sockets to better cope with large writes operations. - Store netdevs in an xarray, to simplify iterating over netdevs. - Refactor nexthop selection for multipath routes. - Improve sched class lifetime handling. - Add backup nexthop ID support for bridge. - Implement drop reasons support in openvswitch. - Several data races annotations and fixes. - Constify the sk parameter of routing functions. - Prepend kernel version to netconsole message. Protocols --------- - Implement support for TCP probing the peer being under memory pressure. - Remove hard coded limitation on IPv6 specific info placement inside the socket struct. - Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated per socket scaling factor. - Scaling-up the IPv6 expired route GC via a separated list of expiring routes. - In-kernel support for the TLS alert protocol. - Better support for UDP reuseport with connected sockets. - Add NEXT-C-SID support for SRv6 End.X behavior, reducing the SR header size. - Get rid of additional ancillary per MPTCP connection struct socket. - Implement support for BPF-based MPTCP packet schedulers. - Format MPTCP subtests selftests results in TAP. - Several new SMC 2.1 features including unique experimental options, max connections per lgr negotiation, max links per lgr negotiation. BPF --- - Multi-buffer support in AF_XDP. - Add multi uprobe BPF links for attaching multiple uprobes and usdt probes, which is significantly faster and saves extra fds. - Implement an fd-based tc BPF attach API (TCX) and BPF link support on top of it. - Add SO_REUSEPORT support for TC bpf_sk_assign. - Support new instructions from cpu v4 to simplify the generated code and feature completeness, for x86, arm64, riscv64. - Support defragmenting IPv(4|6) packets in BPF. - Teach verifier actual bounds of bpf_get_smp_processor_id() and fix perf+libbpf issue related to custom section handling. - Introduce bpf map element count and enable it for all program types. - Add a BPF hook in sys_socket() to change the protocol ID from IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy. - Introduce bpf_me_mcache_free_rcu() and fix OOM under stress. - Add uprobe support for the bpf_get_func_ip helper. - Check skb ownership against full socket. - Support for up to 12 arguments in BPF trampoline. - Extend link_info for kprobe_multi and perf_event links. Netfilter --------- - Speed-up process exit by aborting ruleset validation if a fatal signal is pending. - Allow NLA_POLICY_MASK to be used with BE16/BE32 types.

samples/bpf: Remove the xdp_sample_pkts utility
The functionality of this utility is covered by the xdpdump utility in xdp-tools. There's a slight difference in usage as the xdpdump utility's main focus is to dump packets before or after they are processed by an existing XDP program. However, xdpdump also has the --load-xdp-program switch, which will make it attach its own program if no existing program is loaded. With this, xdp_sample_pkts usage can be converted as: xdp_sample_pkts eth0 --> xdpdump --load-xdp-program eth0 To get roughly equivalent behaviour.

samples/bpf: Remove the xdp1 and xdp2 utilities
The functionality of these utilities have been incorporated into the xdp-bench utility in xdp-tools. Equivalent functionality is: xdp1 eth0 --> xdp-bench drop -p parse-ip -l load-bytes eth0 xdp2 eth0 --> xdp-bench drop -p swap-macs eth0 Note that there's a slight difference in behaviour of those examples: the swap-macs operation of xdp-bench doesn't use the bpf_xdp_load_bytes() helper to load the packet data, whereas the xdp2 utility did so unconditionally. For the parse-ip action the use of bpf_xdp_load_bytes() can be selected by the '-l load-bytes' switch, with the difference that the xdp-bench utility will perform two separate calls to the helper, one to load the ethernet header and another to load the IP header; where the xdp1 utility only performed one call always loading 60 bytes of data.

samples/bpf: simplify spintest with kprobe.multi
With the introduction of kprobe.multi, it is now possible to attach multiple kprobes to a single BPF program without the need for multiple definitions. Additionally, this method supports wildcard-based matching, allowing for further simplification of BPF programs. In here, an asterisk (*) wildcard is used to map to all symbols relevant to spin_{lock|unlock}. Furthermore, since kprobe.multi handles symbol matching, this commit eliminates the need for the previous logic of reading the ksym table to verify the existence of symbols. Signed-off-by: Daniel T.

samples/bpf: make tracing programs to be more CO-RE centric
The existing tracing programs have been developed for a considerable period of time and, as a result, do not properly incorporate the features of the current libbpf, such as CO-RE. This is evident in frequent usage of functions like PT_REGS* and the persistence of "hack" methods using underscore-style bpf_probe_read_kernel from the past. These programs are far behind the current level of libbpf and can potentially confuse users. Therefore, this commit aims to convert the outdated BPF programs to be more CO-RE centric.

samples/bpf: convert to vmlinux.h with tracing programs
This commit replaces separate headers with a single vmlinux.h to tracing programs. Thanks to that, we no longer need to define the argument structure for tracing programs directly. For example, argument for the sched_switch tracpepoint (sched_switch_args) can be replaced with the vmlinux.h provided trace_event_raw_sched_switch. Additional defines have been added to the BPF program either directly or through the inclusion of net_shared.h. Defined values are PERF_MAX_STACK_DEPTH, IFNAMSIZ constants and __stringify() macro. This change enables the BPF program to access internal structures with BTF generated "vmlinux.h" header. Signed-off-by: Daniel T.

So symbol_put must be replaced with __symbol_put. When we uninstall hw_breakpoint.ko (rmmod), a kernel bug occurs with the following error: [11381.854152] kernel BUG at kernel/module/main.c:779!

The flag FBINFO_DEFAULT is 0 and has no effect, as struct fbinfo.flags has been allocated to zero by framebuffer_alloc(). So do not set it. Flags should signal differences from the default values.

arm64: ftrace: Add direct call trampoline samples support
The ftrace samples need per-architecture trampoline implementations to save and restore argument registers around the calls to my_direct_func* and to restore polluted registers (eg: x30). These samples also include <asm/asm-offsets.h> which, on arm64, is not necessary and redefines previously defined macros (resulting in warnings) so these includes are guarded by !CONFIG_ARM64.

samples: pktgen: fix append mode failed issue
Each sample script sources functions.sh before parameters.sh which makes $APPEND undefined when trapping EXIT no matter in append mode or not. Due to this when sample scripts finished they always do "pgctrl reset" which resets pktgen config. So move trap to each script after sourcing parameters.sh and trap EXIT explicitly.

Probes updates for v6.5:
- fprobe: Pass return address to the fprobe entry/exit callbacks so that the callbacks don't need to analyze pt_regs/stack to find the function return address. - kprobe events: cleanup usage of TPARG_FL_FENTRY and TPARG_FL_RETURN flags so that those are not set at once. - fprobe events: . Add a new fprobe events for tracing arbitrary function entry and exit as a trace event. . Add a new tracepoint events for tracing raw tracepoint as a trace event. This allows user to trace non user-exposed tracepoints. . Move eprobe's event parser code into probe event common file. . Introduce BTF (BPF type format) support to kernel probe (kprobe, fprobe and tracepoint probe) events so that user can specify traced function arguments by name. This also applies the type of argument when fetching the argument. . Introduce '$arg*' wildcard support if BTF is available. This expands the '$arg*' meta argument to all function argument automatically. . Check the return value types by BTF. If the function returns 'void', '$retval' is rejected. . Add some selftest script for fprobe events, tracepoint events and BTF support. . Update documentation about the fprobe events. . Some fixes for above features, document and selftests. - selftests for ftrace (except for new fprobe events): . Add a test case for multiple consecutive probes in a function which checks if ftrace based kprobe, optimized kprobe and normal kprobe can be defined in the same target function. . Add a test case for optimized probe, which checks whether kprobe can be optimized or not. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEh7BulGwFlgAOi5DV2/sHvwUrPxsFAmSa+9MACgkQ2/sHvwUr PxsmOAgAmUOIWtvH5py7AZpIRhCj8B18F6KnT7w2hByCsRxf7SaCqMhpBCk9VnYv 9fJFBHpvYRJEmpHoH3o2ET5AGfKVNac9z96AGI2qJ4ECWITd6I5+WfTdZ5ueVn2d f6DQ10mHXDHSMFbuqfYWSHtkeivJpWpUNHhwzPb4doNOe06bZNfVuSgnksFg1at5 kq16HbvGnhPzdO4YHmvqwjmRHr5/nCI1KDE9xIBcqNtWFbiRigC11zaZEUkLX+vT F63ShyfCK718AiwDfnjXpGkXAiVOZuAIR8RELaSqQ92YHCFKq5k9K4++WllPR5f9 AxjVultFDiCd4oSPgYpQkjuZdFq9NA== =IhmY -----END PGP SIGNATURE----- Merge tag 'probes-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull probes updates from Masami Hiramatsu: - fprobe: Pass return address to the fprobe entry/exit callbacks so that the callbacks don't need to analyze pt_regs/stack to find the function return address. - kprobe events: cleanup usage of TPARG_FL_FENTRY and TPARG_FL_RETURN flags so that those are not set at once. - fprobe events: - Add a new fprobe events for tracing arbitrary function entry and exit as a trace event. - Add a new tracepoint events for tracing raw tracepoint as a trace event.

bpf: Replace deprecated -target with --target= for Clang
The -target option has been deprecated since clang 3.4 in 2013. Therefore, use
the preferred --target=bpf form instead. This also matches how we use --target=
in scripts/Makefile.clang.

Rework the handling of unexpected-end-of-file to invoke an additional callback instead of trying to predict what the right combination of MORE/NOTLAST flags is. Remove the MSG_SENDPAGE_NOTLAST flag completely. - Implement SCM_PIDFD, a new type of CMSG type analogous to SCM_CREDENTIALS, but it contains pidfd instead of plain pid. - Enable socket busy polling with CONFIG_RT. - Improve reliability and efficiency of reporting for ref_tracker. - Auto-generate a user space C library for various Netlink families. Protocols --------- - Allow TCP to shrink the advertised window when necessary, prevent sk_rcvbuf auto-tuning from growing the window all the way up to tcp_rmem[2]. - Use per-VMA locking for "page-flipping" TCP receive zerocopy. - Prepare TCP for device-to-device data transfers, by making sure that payloads are always attached to skbs as page frags. - Make the backoff time for the first N TCP SYN retransmissions linear. Exponential backoff is unnecessarily conservative. - Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO). - Avoid waking up applications using TLS sockets until we have a full record. - Allow using kernel memory for protocol ioctl callbacks, paving the way to issuing ioctls over io_uring. - Add nolocalbypass option to VxLAN, forcing packets to be fully encapsulated even if they are destined for a local IP address. - Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure in-kernel ECMP implementation (e.g. Open vSwitch) select the same link for all packets. Support L4 symmetric hashing in Open vSwitch. - PPPoE: make number of hash bits configurable. - Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client (ipconfig). - Add layer 2 miss indication and filtering, allowing higher layers (e.g. ACL filters) to make forwarding decisions based on whether packet matched forwarding state in lower devices (bridge). - Support matching on Connectivity Fault Management (CFM) packets. - Hide the "link becomes ready" IPv6 messages by demoting their printk level to debug. - HSR: don't enable promiscuous mode if device offloads the proto. - Support active scanning in IEEE 802.15.4. - Continue work on Multi-Link Operation for WiFi 7. BPF --- - Add precision propagation for subprogs and callbacks. This allows maintaining verification efficiency when subprograms are used, or in fact passing the verifier at all for complex programs, especially those using open-coded iterators. - Improve BPF's {g,s}setsockopt() length handling. Previously BPF assumed the length is always equal to the amount of written data. But some protos allow passing a NULL buffer to discover what the output buffer *should* be, without writing anything. - Accept dynptr memory as memory arguments passed to helpers. - Add routing table ID to bpf_fib_lookup BPF helper. - Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands. - Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark maps as read-only). - Show target_{obj,btf}_id in tracing link fdinfo. - Addition of several new kfuncs (most of the names are self-explanatory): - Add a set of new dynptr kfuncs: bpf_dynptr_adjust(), bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size() and bpf_dynptr_clone(). - bpf_task_under_cgroup() - bpf_sock_destroy() - force closing sockets - bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs Netfilter --------- - Relax set/map validation checks in nf_tables. Allow checking presence of an entry in a map without using the value. - Increase ip_vs_conn_tab_bits range for 64BIT builds. - Allow updating size of a set. - Improve NAT tuple selection when connection is closing. Driver API ---------- - Integrate netdev with LED subsystem, to allow configuring HW "offloaded" blinking of LEDs based on link state and activity (i.e. packets coming in and out). - Support configuring rate selection pins of SFP modules. - Factor Clause 73 auto-negotiation code out of the drivers, provide common helper routines. - Add more fool-proof helpers for managing lifetime of MDIO devices associated with the PCS layer. - Allow drivers to report advanced statistics related to Time Aware scheduler offload (taprio). - Allow opting out of VF statistics in link dump, to allow more VFs to fit into the message. - Split devlink instance and devlink port operations.

kmemleak-test: drop __init to get better backtrace

samples/bpf: xdp1 and xdp2 reduce XDPBUFSIZE to 60
Default samples/pktgen scripts send 60 byte packets as hardware adds
4-bytes FCS checksum, which fulfils minimum Ethernet 64 bytes frame
size.
XDP layer will not necessary have access to the 4-bytes FCS checksum.
This leads to bpf_xdp_load_bytes() failing as it tries to copy 64-bytes
from an XDP packet that only have 60-bytes available.

LoongArch: ftrace: Add direct call trampoline samples support
The ftrace samples need per-architecture trampoline implementations to save and restore argument registers around the calls to my_direct_func* and to restore polluted registers (e.g: ra).

Rust changes for v6.4
More additions to the Rust core. Importantly, this adds the pin-init API, which will be used by other abstractions, such as the synchronization ones added here too: - pin-init API: a solution for the safe pinned initialization problem. This allows to reduce the need for 'unsafe' code in the kernel when dealing with data structures that require a stable address. Commit |
