This patch added the self test for MP_FASTCLOSE. Reused the argument addr_nr_ns2 of do_transfer() to pass the extra arguments '-I 2' to mptcp_connect commands. Then mptcp_connect disconnected the connections to trigger the MP_FASTCLOSE sending and receiving. Used chk_fclose_nr to check the MP_FASTCLOSE mibs and used chk_rst_nr to check the MP_RST mibs. This test used the test_linkfail value to make 1024KB test files. The output looks like this: Created /tmp/tmp.XB8sfv1hJ0 (size 1024 KB) containing data sent by client Created /tmp/tmp.RtTDbzqrXI (size 1024 KB) containing data sent by server 001 fastclose test syn[ ok ] - synack[ ok ] - ack[ ok ] ctx[ ok ] - fclzrx[ ok ] rtx[ ok ] - rstrx [ ok ] invert Signed-off-by:Geliang Tang <geliang.tang@suse.com> Signed-off-by:

This patch reused the test_linkfail values above 2 to make test files with the given sizes (KB) for both the client side and the server side. It's useful for the test cases using different file sizes. Signed-off-by:

Instead of using a global variable mptcp_connect, this patch added a new local variable extra_args in do_transfer() to store the extra arguments passing to the mptcp_connect commands. This patch also renamed the speed level 'least' to 'speed_*'. This more flexible way can avoid the need to add new speed levels in the future. Signed-off-by:

This patch added a new function chk_rst_nr() to check the numbers of the MP_RST sending and receiving mibs. Showed in the output whether the inverted namespaces check order is used. Since if we pass -Cz to mptcp_join.sh, the MP_RST information is showed twice. Signed-off-by:

This patch added two more mibs for MP_FASTCLOSE, MPTCP_MIB_MPFASTCLOSETX for the MP_FASTCLOSE sending and MPTCP_MIB_MPFASTCLOSERX for receiving. Also added a debug log for MP_FASTCLOSE receiving, printed out the recv_key of MP_FASTCLOSE in mptcp_parse_option to show that MP_RST is received. Signed-off-by:

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypassed the hierarchical setup and messed up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq(). Signed-off-by:

The variables 'res' inside the functions sparx5_ptp_get_1ppm and sparx5_ptp_get_nominal_value was not initialized. So in case of the default case of the switch after, it would return an uninitialized variable. This makes also the clang builds to failed.

The main changes are: 1) Optimize BPF stackmap's build_id retrieval by caching last valid build_id, as consecutive stack frames are likely to be in the same VMA and therefore have the same build id, from Hao Luo. 2) Several improvements to arm64 BPF JIT, that is, support for JITing the atomic[64]_fetch_add, atomic[64]_[fetch_]{and,or,xor} and lastly atomic[64]_{xchg|cmpxchg}. Also fix the BTF line info dump for JITed programs, from Hou Tao. 3) Optimize generic BPF map batch deletion by only enforcing synchronize_rcu() barrier once upon return to user space, from Eric Dumazet. 4) For kernel build parse DWARF and generate BTF through pahole with enabled multithreading, from Kui-Feng Lee. 5) BPF verifier usability improvements by making log info more concise and replacing inv with scalar type name, from Mykola Lysenko. 6) Two follow-up fixes for BPF prog JIT pack allocator, from Song Liu. 7) Add a new Kconfig to allow for loading kernel modules with non-matching BTF type info; their BTF info is then removed on load, from Connor O'Brien. 8) Remove reallocarray() usage from bpftool and switch to libbpf_reallocarray() in order to fix compilation errors for older glibc, from Mauricio Vásquez. 9) Fix libbpf to error on conflicting name in BTF when type declaration appears before the definition, from Xu Kuohai. 10) Fix issue in BPF preload for in-kernel light skeleton where loaded BPF program fds prevent init process from setting up fd 0-2, from Yucong Sun. 11) Fix libbpf reuse of pinned perf RB map when max_entries is auto-determined by libbpf, from Stijn Tintel. 12) Several cleanups for libbpf and a fix to enforce perf RB map #pages to be non-zero, from Yuntao Wang. * https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (32 commits) bpf: Small BPF verifier log improvements libbpf: Add a check to ensure that page_cnt is non-zero bpf, x86: Set header->size properly before freeing it x86: Disable HAVE_ARCH_HUGE_VMALLOC on 32-bit x86 bpf, test_run: Fix overflow in XDP frags bpf_test_finish selftests/bpf: Update btf_dump case for conflicting names libbpf: Skip forward declaration when counting duplicated type names bpf: Add some description about BPF_JIT_ALWAYS_ON in Kconfig bpf, docs: Add a missing colon in verifier.rst bpf: Cache the last valid build_id libbpf: Fix BPF_MAP_TYPE_PERF_EVENT_ARRAY auto-pinning bpf, selftests: Use raw_tp program for atomic test bpf, arm64: Support more atomic operations bpftool: Remove redundant slashes bpf: Add config to allow loading modules with BTF mismatches bpf, arm64: Feed byte-offset into bpf line info bpf, arm64: Call build_prologue() first in first JIT pass bpf: Fix issue with bpf preload module taking over stdout/stdin of kernel. bpftool: Bpf skeletons assert type sizes bpf: Cleanup comments ... ==================== Link: https://lore.kernel.org/r/20220304164313.31675-1-daniel@iogearbox.netSigned-off-by:

The field adv_instance_cnt is always accessed within a device lock, except in the function add_advertising. A concurrent remove of an advertisement with adding another one could result in the if check "if a new instance was actually added" to not trigger, resulting in not triggering the "advertising added event".

Both hci_find_adv_instance and hci_remove_adv_instance have a comment above their function definition saying that these two functions require the caller to hold the hdev->lock lock. However, hci_le_ext_adv_term_evt does not acquire that lock and neither does its caller hci_le_meta_evt (hci_le_meta_evt calls hci_le_ext_adv_term_evt via an indirect function call because of the lookup in hci_le_ev_table). The other event handlers all acquire and release the hdev->lock and they follow the rule that hci_find_adv_instance and hci_remove_adv_instance must be called while holding the hdev->lock lock. The solution is to make sure hci_le_ext_adv_term_evt also acquires and releases the hdev->lock lock. The check on ev->status which logs a warning and does an early return is not covered by the lock because other functions also access ev->status without holding the lock. Signed-off-by:

There is a conflict between MediaTek wmt event and msft vendor extension logic in the core layer since 145373cb ("Bluetooth: Add framework for Microsoft vendor extension") was introduced because we changed the type of mediatek wmt event to the type of msft vendor event in the driver. But the purpose we reported mediatek event to the core layer is for the diagnostic purpose with that we are able to see the full packet trace via monitoring socket with btmon. Thus, it is harmless we keep the original type of mediatek vendor event here to avoid breaking the msft extension function especially they can be supported by Mediatek chipset like MT7921 , MT7922 devices and future devices.

This patch introduce eir_skb_put_data() that can be used to simplify operations on eir in goal of eliminating the necessity of intermediary buffers. eir_skb_put_data() is in pair to what eir_append_data() does with help of eir_len, but without awkwardness when passing return value to skb_put() (as it returns updated offset not size).

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use "flexible array members" for these cases. The older style of one-element or zero-length arrays should no longer be used.

Since the starting value in the for loop is greater than or equal to 1, the restriction is CAS_FLAG_REG_PLUS is in the file cassini.h is defined as 0x1 by macro, and the for loop and if condition is not satisfied, so the code here is redundant. Clean up the following smatch warning: drivers/net/ethernet/sun/cassini.c:3513 cas_start_dma() warn: we never enter this loop. drivers/net/ethernet/sun/cassini.c:1239 cas_init_rx_dma() warn: we never enter this loop. drivers/net/ethernet/sun/cassini.c:1247 cas_init_rx_dma() warn: we never enter this loop.

Simon Horman says: ==================== Add AF_XDP zero-copy support for NFP Niklas Söderlund says: This series adds AF_XDP zero-copy support for the NFP driver. The series is based on previous work done by Jakub Kicinski. Patch 1/5 and 2/5 prepares the driver for AF_XDP support by refactoring functions that will act differently once AF_XDP is active or not making the driver easier to read and by preparing some functions to be reused outside the local file scope. Patch 3/5 and 4/5 prepares the driver for dealing the UMEM while finally patch 5/5 adds AF_XDP support. Based on work by Jakub Kicinski. ==================== Signed-off-by: -

This patch adds zero-copy Rx and Tx support for AF_XDP sockets. It do so by adding a separate NAPI poll function that is attached to a each channel when the XSK socket is attached with XDP_SETUP_XSK_POOL, and restored when the XSK socket is terminated, this is done per channel. Support for XDP_TX is implemented and the XDP buffer can safely be moved from the Rx to the Tx queue and correctly freed and returned to the XSK pool once it's transmitted. Note that when AF_XDP zero-copy is enabled, the XDP action XDP_PASS will allocate a new buffer and copy the zero-copy frame prior passing it to the kernel stack. This patch is based on previous work by Jakub Kicinski. Signed-off-by:
