2025-10-17selftests/bpf: Fix redefinition of 'off' as different kind of symbolBrahmajit Das1-7/+7
This fixes the following build error CLNG-BPF [test_progs] verifier_global_ptr_args.bpf.o progs/verifier_global_ptr_args.c:228:5: error: redefinition of 'off' as different kind of symbol 228 | u32 off; | ^ The symbol 'off' was previously defined in tools/testing/selftests/bpf/tools/include/vmlinux.h, which includes an enum i40e_ptp_gpio_pin_state from drivers/net/ethernet/intel/i40e/i40e_ptp.c: enum i40e_ptp_gpio_pin_state { end = -2, invalid = -1, off = 0, in_A = 1, in_B = 2, out_A = 3, out_B = 4, }; This enum is included when CONFIG_I40E is enabled. As of commit 032676ff8217 ("LoongArch: Update Loongson-3 default config file"), CONFIG_I40E is set in the defconfig, which leads to the conflict. Renaming the local variable avoids the redefinition and allows the build to succeed.

2025-10-10selftests/bpf: Add test for unpinning htab with internal timer structKaFai Wan1-0/+25
Add test to verify that unpinning hash tables containing internal timer structures does not trigger context warnings. Each subtest (timer_prealloc and timer_no_prealloc) can trigger the context warning when unpinning, but the warning cannot be triggered twice within a short time interval (a HZ), which is expected behavior.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "Core & protocols: - Improve drop account scalability on NUMA hosts for RAW and UDP sockets and the backlog, almost doubling the Pps capacity under DoS - Optimize the UDP RX performance under stress, reducing contention, revisiting the binary layout of the involved data structs and implementing NUMA-aware locking. This improves UDP RX performance by an additional 50%, even more under extreme conditions - Add support for PSP encryption of TCP connections; this mechanism has some similarities with IPsec and TLS, but offers superior HW offloads capabilities - Ongoing work to support Accurate ECN for TCP. AccECN allows more than one congestion notification signal per RTT and is a building block for Low Latency, Low Loss, and Scalable Throughput (L4S) - Reorganize the TCP socket binary layout for data locality, reducing the number of touched cachelines in the fastpath - Refactor skb deferral free to better scale on large multi-NUMA hosts, this improves TCP and UDP RX performances significantly on such HW - Increase the default socket memory buffer limits from 256K to 4M to better fit modern link speeds - Improve handling of setups with a large number of nexthop, making dump operating scaling linearly and avoiding unneeded synchronize_rcu() on delete - Improve bridge handling of VLAN FDB, storing a single entry per bridge instead of one entry per port; this makes the dump order of magnitude faster on large switches - Restore IP ID correctly for encapsulated packets at GSO segmentation time, allowing GRO to merge packets in more scenarios - Improve netfilter matching performance on large sets - Improve MPTCP receive path performance by leveraging recently introduced core infrastructure (skb deferral free) and adopting recent TCP autotuning changes - Allow bridges to redirect to a backup port when the bridge port is administratively down - Introduce MPTCP 'laminar' endpoint that con be used only once per connection and simplify common MPTCP setups - Add RCU safety to dst->dev, closing a lot of possible races - A significant crypto library API for SCTP, MPTCP and IPv6 SR, reducing code duplication - Supports pulling data from an skb frag into the linear area of an XDP buffer Things we sprinkled into general kernel code: - Generate netlink documentation from YAML using an integrated YAML parser Driver API: - Support using IPv6 Flow Label in Rx hash computation and RSS queue selection - Introduce API for fetching the DMA device for a given queue, allowing TCP zerocopy RX on more H/W setups - Make XDP helpers compatible with unreadable memory, allowing more easily building DevMem-enabled drivers with a unified XDP/skbs datapath - Add a new dedicated ethtool callback enabling drivers to provide the number of RX rings directly, improving efficiency and clarity in RX ring queries and RSS configuration - Introduce a burst period for the health reporter, allowing better handling of multiple errors due to the same root cause - Support for DPLL phase offset exponential moving average, controlling the average smoothing factor Device drivers: -

2025-09-26mptcp: pm: rename 'subflows' to 'extra_subflows'Matthieu Baerts (NGI0)1-1/+1
A few variables linked to the Path-Managers are confusing, and it would help current and future developers, to clarify them. One of them is 'subflows', which in fact represents the number of extra subflows: all the additional subflows created after the initial one, and not the total number of subflows. While at it, add an additional name for the corresponding variable in MPTCP INFO: mptcpi_extra_subflows. Not to break the current uAPI, the new name is added as a 'define' pointing to the former name. This will then also help userspace devs. No functional changes intended.

Further debugging at llvm side shows that llvm commit ([1]) caused the failure. For the original code: page[i] = NULL; page[i + 1] = NULL; the llvm transformed it to something like below at source level: __builtin_memset(&page[i], 0, 16) Such transformation prevents llvm BPFCheckAndAdjustIR pass from generating proper addr_space_cast insns ([2]). Adding support in llvm BPFCheckAndAdjustIR pass should work, but not sure that such a pattern exists or not in real applications. At the same time, simply adding a memory barrier between two 'page' assignment can fix the issue.

2025-09-18bpf: Return hashes of maps in BPF_OBJ_GET_INFO_BY_FDKP Singh1-2/+5
Currently only array maps are supported, but the implementation can be extended for other maps and objects. The hash is memoized only for exclusive and frozen maps as their content is stable until the exclusive program modifies the map. This is required for BPF signing, enabling a trusted loader program to verify a map's integrity. The loader retrieves the map's runtime hash from the kernel and compares it against an expected hash computed at build time.

2025-09-18bpf: Enforce RCU protection for KF_RCU_PROTECTEDKumar Kartikeya Dwivedi2-3/+3
Currently, KF_RCU_PROTECTED only applies to iterator APIs and that too in a convoluted fashion: the presence of this flag on the kfunc is used to set MEM_RCU in iterator type, and the lack of RCU protection results in an error only later, once next() or destroy() methods are invoked on the iterator. While there is no bug, this is certainly a bit unintuitive, and makes the enforcement of the flag iterator specific. In the interest of making this flag useful for other upcoming kfuncs, e.g. scx_bpf_cpu_curr() [0][1], add enforcement for invoking the kfunc in an RCU critical section in general. This would also mean that iterator APIs using KF_RCU_PROTECTED will error out earlier, instead of throwing an error for lack of RCU CS protection when next() or destroy() methods are invoked. In addition to this, if the kfuncs tagged KF_RCU_PROTECTED return a pointer value, ensure that this pointer value is only usable in an RCU critical section. There might be edge cases where the return value is special and doesn't need to imply MEM_RCU semantics, but in general, the assumption should hold for the majority of kfuncs, and we can revisit things if necessary later.

Make sure that we only switch the cgroup namespace and enter a new cgroup in a child process separate from test_progs, to not mess up the environment for subsequent tests. To remove this cgroup, we need to wait for the child to exit, and then rmdir its cgroup. If the read call fails, or waitpid succeeds, we know the child exited (read call would fail when the last pipe end is closed, otherwise waitpid waits until exit(2) is called). We then invoke a newly introduced remove_cgroup_pid() helper, that identifies cgroup path using the passed in pid of the now dead child, instead of using the current process pid (getpid()).

2025-09-09selftests/bpf: Fix "expression result unused" warnings with iceccIlya Leoshkevich2-5/+4
icecc is a compiler wrapper that distributes compile jobs over a build farm [1]. It works by sending toolchain binaries and preprocessed source code to remote machines. Unfortunately using it with BPF selftests causes build failures due to a clang bug [2]. The problem is that clang suppresses the -Wunused-value warning if the unused expression comes from a macro expansion. Since icecc compiles preprocessed source code, this information is not available. This leads to -Wunused-value false positives. obj_new_no_struct() and obj_new_acq() use the bpf_obj_new() macro and discard the result. arena_spin_lock_slowpath() uses two macros that produce values and ignores the results. Add (void) casts to explicitly indicate that this is intentional and suppress the warning. An alternative solution is to change the macros to not produce values. This would work today for the arena_spin_lock_slowpath() issue, but in the future there may appear users who need them. Another potential solution is to replace these macros with functions. Unfortunately this would not work, because these macros work with unknown types and control flow.

Add the testing "kprobe-multi-all", which will hook all the kernel functions during the benchmark. And the "kretprobe-multi-all" is added too.
