2024-06-05libbpf: Add BTF field iteratorAndrii Nakryiko
Implement iterator-based type ID and string offset BTF field iterator. This is used extensively in BTF-handling code and BPF linker code for various sanity checks, rewriting IDs/offsets, etc. Currently this is implemented as visitor pattern calling custom callbacks, which makes the logic (especially in simple cases) unnecessarily obscure and harder to follow. Having equivalent functionality using iterator pattern makes for simpler to understand and maintain code. As we add more code for BTF processing logic in libbpf, it's best to switch to iterator pattern before adding more callback-based code. The idea for iterator-based implementation is to record offsets of necessary fields within fixed btf_type parts (which should be iterated just once), and, for kinds that have multiple members (based on vlen field), record where in each member necessary fields are located. Generic iteration code then just keeps track of last offset that was returned and handles N members correctly. Return type is just u32 pointer, where NULL is returned when all relevant fields were already iterated.

2024-06-05net: ethernet: mtk_eth_soc: handle dma buffer size soc specificFrank Wunderlich
The mainline MTK ethernet driver suffers long time from rarly but annoying tx queue timeouts. We think that this is caused by fixed dma sizes hardcoded for all SoCs. We suspect this problem arises from a low level of free TX DMADs, the TX Ring alomost full. The transmit timeout is caused by the Tx queue not waking up. The Tx queue stops when the free counter is less than ring->thres, and it will wake up once the free counter is greater than ring->thres. If the CPU is too late to wake up the Tx queues, it may cause a transmit timeout. Therefore, we increased the TX and RX DMADs to improve this error situation. Use the dma-size implementation from SDK in a per SoC manner. In difference to SDK we have no RSS feature yet, so all RX/TX sizes should be raised from 512 to 2048 byte except fqdma on mt7988 to avoid the tx timeout issue.

2024-06-05tcp: derive delack_max with tcp_rto_min helperKevin Yang
Rto_min now has multiple sources, ordered by preprecedence high to low: ip route option rto_min, icsk->icsk_rto_min. When derive delack_max from rto_min, we should not only use ip route option, but should use tcp_rto_min helper to get the correct rto_min.

2024-06-05rtnetlink: make the "split" NLM_DONE handling genericJakub Kicinski
Jaroslav reports Dell's OMSA Systems Management Data Engine expects NLM_DONE in a separate recvmsg(), both for rtnl_dump_ifinfo() and inet_dump_ifaddr(). We already added a similar fix previously in commit 460b0d33cf10 ("inet: bring NLM_DONE out to a separate recv() again") Instead of modifying all the dump handlers, and making them look different than modern for_each_netdev_dump()-based dump handlers - put the workaround in rtnetlink code. This will also help us move the custom rtnl-locking from af_netlink in the future (in net-next). Note that this change is not touching rtnl_dump_all(). rtnl_dump_all() is different kettle of fish and a potential problem. We now mix families in a single recvmsg(), but NLM_DONE is not coalesced. Tested: ./cli.py --dbg-small-recv 4096 --spec netlink/specs/rt_addr.yaml \ --dump getaddr --json '{"ifa-family": 2}' ./cli.py --dbg-small-recv 4096 --spec netlink/specs/rt_route.yaml \ --dump getroute --json '{"rtm-family": 2}' ./cli.py --dbg-small-recv 4096 --spec netlink/specs/rt_link.yaml \ --dump getlink Fixes: 3e41af90767d ("rtnetlink: use xarray iterator to implement rtnl_dump_ifinfo()") Fixes: cdb2f80f1c10 ("inet: use xa_array iterator to implement inet_dump_ifaddr()") Reported-by: Jaroslav Pulchart <jaroslav.pulchart@gooddata.com> Link: https://lore.kernel.org/all/CAK8fFZ7MKoFSEzMBDAOjoUt+vTZRRQgLDNXEOfdCCXSoXXKE0g@mail.gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> Reviewed-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2024-06-05mptcp: count CLOSE-WAIT sockets for MPTCP_MIB_CURRESTABJason Xing
Like previous patch does in TCP, we need to adhere to RFC 1213: "tcpCurrEstab OBJECT-TYPE ... The number of TCP connections for which the current state is either ESTABLISHED or CLOSE- WAIT." So let's consider CLOSE-WAIT sockets. The logic of counting When we increment the counter? a) Only if we change the state to ESTABLISHED. When we decrement the counter? a) if the socket leaves ESTABLISHED and will never go into CLOSE-WAIT, say, on the client side, changing from ESTABLISHED to FIN-WAIT-1. b) if the socket leaves CLOSE-WAIT, say, on the server side, changing from CLOSE-WAIT to LAST-ACK.

2024-06-05tcp: count CLOSE-WAIT sockets for TCP_MIB_CURRESTABJason Xing
According to RFC 1213, we should also take CLOSE-WAIT sockets into consideration: "tcpCurrEstab OBJECT-TYPE ... The number of TCP connections for which the current state is either ESTABLISHED or CLOSE- WAIT." After this, CurrEstab counter will display the total number of ESTABLISHED and CLOSE-WAIT sockets. The logic of counting When we increment the counter? a) if we change the state to ESTABLISHED. b) if we change the state from SYN-RECEIVED to CLOSE-WAIT. When we decrement the counter? a) if the socket leaves ESTABLISHED and will never go into CLOSE-WAIT, say, on the client side, changing from ESTABLISHED to FIN-WAIT-1. b) if the socket leaves CLOSE-WAIT, say, on the server side, changing from CLOSE-WAIT to LAST-ACK. Please note: there are two chances that old state of socket can be changed to CLOSE-WAIT in tcp_fin(). One is SYN-RECV, the other is ESTABLISHED. So we have to take care of the former case.

2024-06-05octeontx2-af: Add debugfs support to dump NIX TM topologyAnshumali Gaur
This patch adds support to dump NIX transmit queue topology. There are multiple levels of scheduling/shaping supported by NIX and a packet traverses through multiple levels before sending the packet out. At each level, there are set of scheduling/shaping rules applied to a packet flow. Each packet traverses through multiple levels SQ->SMQ->TL4->TL3->TL2->TL1 and these levels are mapped in a parent-child relationship. This patch dumps the debug information related to all TM Levels in the following way. Example: $ echo <nixlf> > /sys/kernel/debug/octeontx2/nix/tm_tree $ cat /sys/kernel/debug/octeontx2/nix/tm_tree A more desriptive set of registers at each level can be dumped in the following way.

Drop the second snapshot of mmu_invalidate_seq in kvm_faultin_pfn(). Before checking the mismatch of private vs. shared, mmu_invalidate_seq is saved to fault->mmu_seq, which can be used to detect an invalidation related to the gfn occurred, i.e. KVM will not install a mapping in page table if fault->mmu_seq != mmu_invalidate_seq. Currently there is a second snapshot of mmu_invalidate_seq, which may not be same as the first snapshot in kvm_faultin_pfn(), i.e. the gfn attribute may be changed between the two snapshots, but the gfn may be mapped in page table without hindrance. Therefore, drop the second snapshot as it has no obvious benefits.

2024-06-05vxlan: Fix regression when dropping packets due to invalid src addressesDaniel Borkmann
Commit f58f45c1e5b9 ("vxlan: drop packets from invalid src-address") has recently been added to vxlan mainly in the context of source address snooping/learning so that when it is enabled, an entry in the FDB is not being created for an invalid address for the corresponding tunnel endpoint. Before commit f58f45c1e5b9 vxlan was similarly behaving as geneve in that it passed through whichever macs were set in the L2 header. It turns out that this change in behavior breaks setups, for example, Cilium with netkit in L3 mode for Pods as well as tunnel mode has been passing before the change in f58f45c1e5b9 for both vxlan and geneve. After mentioned change it is only passing for geneve as in case of vxlan packets are dropped due to vxlan_set_mac() returning false as source and destination macs are zero which for E/W traffic via tunnel is totally fine. Fix it by only opting into the is_valid_ether_addr() check in vxlan_set_mac() when in fact source address snooping/learning is actually enabled in vxlan. This is done by moving the check into vxlan_snoop(). With this change, the Cilium connectivity test suite passes again for both tunnel flavors.
