This will lead to unsafety as the offset into arena will dereferenced directly without turning it into a base + offset access into the arena region. Since the changes to the x86 JIT will be fairly involved, for now, temporarily disallow use of PTR_TO_ARENA as the destination operand for atomics until support is added to the JIT backend. Fixes: 2fe99eb0ccf2 ("bpf: Add x86-64 JIT support for PROBE_MEM32 pseudo instructions.")

Looking at the GCC internals, the reordering is allowed because the alias analysis thinks that the memcpy() destination and the assignments' left-hand-sides are based on different objects: new_plt and bpf_plt_ret/bpf_plt_target respectively, and therefore they cannot alias. This is in turn due to a violation of the C standard: When two pointers are subtracted, both shall point to elements of the same array object, or one past the last element of the array object ... From the C's perspective, bpf_plt_ret and bpf_plt are distinct objects and cannot be subtracted. In the practical terms, doing so confuses the GCC's alias analysis. The code was written this way in order to let the C side know a few offsets defined in the assembly. While nice, this is by no means necessary. Fix the noncompliance by hardcoding these offsets.

Currently, the offset is being directly used in place of the tmp register which has the offset already loaded by the last emitted instruction. This will cause JIT failures. The easiest way to reproduce this is to test the following code through test_bpf module: { "BPF_LDX_MEMSX | BPF_W", .u.insns_int = { BPF_LD_IMM64(R1, 0x00000000deadbeefULL), BPF_LD_IMM64(R2, 0xffffffffdeadbeefULL), BPF_STX_MEM(BPF_DW, R10, R1, -7), BPF_LDX_MEMSX(BPF_W, R0, R10, -7), BPF_JMP_REG(BPF_JNE, R0, R2, 1), BPF_ALU64_IMM(BPF_MOV, R0, 0), BPF_EXIT_INSN(), }, INTERNAL, { }, { { 0, 0 } }, .stack_depth = 7, }, We need to use the offset as -7 to trigger this code path, there could be other valid ways to trigger this from proper BPF programs as well.

In that case, we might end up with a device that supports wext (but not MLO) in one kernel, and then breaks wext in the future (by enabling MLO), which is not desirable.

This is caused from the driver *only* calling the ice_vsi_free_q_vectors() function by itself, when it is suspending. Since commit b3e7b3a6ee92 ("ice: prevent NULL pointer deref during reload") the driver has zeroed out num_q_vectors, and only restored it in ice_vsi_cfg_def(). This further causes the ice_rebuild() function to allocate a zero length buffer, after which num_q_vectors is updated, and then the new value of num_q_vectors is used to index into the zero length buffer, which corrupts memory. The fix entails making sure all the code referencing num_q_vectors only does so after it has been reset via ice_vsi_cfg_def(). I didn't perform a full bisect, but I was able to test against 6.1.77 kernel and that ice driver works fine for suspend/resume with no panic, so sometime since then, this problem was introduced. Also clean up an un-needed init of a local variable in the function being modified.

The reason is the incompatibility between bpf and riscv abi, that is, bpf will do zero-extension on uint, but riscv64 requires sign-extension on int or uint. We can solve this problem by sign extending the 32-bit parameters in kfunc. The issue is related to [0], and thanks to Yonghong and Alexei.

Symptoms before this commit: On the read channel we always trigger the next read anyhow, so no different behaviour here. On the write channel we may experience timeout errors, because the expected reply will never be received without the retry. Other callers of qeth_send_control_data() may wrongly assume that the ccw was successful, which may cause problems later.

Fortunately Josef Bacik could trigger the issue more often, and could test a patch I wrote two years ago. When TCP sockets are closed, we call inet_csk_clear_xmit_timers() to 'stop' the timers. inet_csk_clear_xmit_timers() can be called from any context, including when socket lock is held. This is the reason it uses sk_stop_timer(), aka del_timer(). This means that ongoing timers might finish much later. For user sockets, this is fine because each running timer holds a reference on the socket, and the user socket holds a reference on the netns. For kernel sockets, we risk that the netns is freed before timer can complete, because kernel sockets do not hold reference on the netns. This patch adds inet_csk_clear_xmit_timers_sync() function that using sk_stop_timer_sync() to make sure all timers are terminated before the kernel socket is released. Modules using kernel sockets close them in their netns exit() handler. Also add sock_not_owned_by_me() helper to get LOCKDEP support : inet_csk_clear_xmit_timers_sync() must not be called while socket lock is held. It is very possible we can revert in the future commit 3a58f13a881e ("net: rds: acquire refcount on TCP sockets") which attempted to solve the issue in rds only. (net/smc/af_smc.c and net/mptcp/subflow.c have similar code) We probably can remove the check_net() tests from tcp_out_of_resources() and __tcp_close() in the future.

For 40MHz XTAL, the core clock frequency must be set to 500MHz. The mt7530_pll_setup() function is responsible of setting the core clock frequency. Currently, it runs on MT7530 with 25MHz and 40MHz XTAL. This causes MT7530 switch with 25MHz XTAL to egress and ingress frames improperly. Introduce a check to run it only on MT7530 with 40MHz XTAL. The core clock frequency is set by writing to a switch PHY's register. Access to the PHY's register is done via the MDIO bus the switch is also on. Therefore, it works only when the switch makes switch PHYs listen on the MDIO bus the switch is on. This is controlled either by the state of the ESW_P1_LED_1 pin after reset deassertion or modifying bit 5 of the modifiable trap register. When ESW_P1_LED_1 is pulled high, PHY indirect access is used. That means accessing PHY registers via the PHY indirect access control register of the switch. When ESW_P1_LED_1 is pulled low, PHY direct access is used. That means accessing PHY registers via the MDIO bus the switch is on. For MT7530 switch with 40MHz XTAL on a board with ESW_P1_LED_1 pulled high, the core clock frequency won't be set to 500MHz, causing the switch to egress and ingress frames improperly. Run mt7530_pll_setup() after PHY direct access is set on the modifiable trap register. With these two changes, all MT7530 switches with 25MHz and 40MHz, and P1_LED_1 pulled high or low, will egress and ingress frames properly.

However, as explained in commit 8bcfb4ae4d97 ("selftests: forwarding: Fix failing tests with old libnet"), old versions of libnet (used by mausezahn) do not use the "SO_BINDTODEVICE" socket option. Specifically, the library started using the option for IPv6 sockets in version 1.1.6 and for IPv4 sockets in version 1.2. This explains why on Ubuntu - which uses version 1.1.6 - the IPv4 overlay tests are failing whereas the IPv6 ones are passing. Fix by specifying the source and destination MAC of the packets which will cause mausezahn to use a packet socket instead of an IP socket.

Around 260s to be exact, and 310s on a debug kernel. The default timeout in selftest is 45sec, so we need an explicit config. Give ourselves some headroom and use 10min.

This should not actually happen, as there are other protections along the way, but we should protect against it anyway. One code path was missing such protections (fixed in the previous patch in the series), causing out-of-bounds array accesses in check_stack_range_initialized(). This patch causes the verification of a program with such a non-sensical access size to fail. This check used to exist in a more indirect way, but was inadvertendly removed in a833a17aeac7.

If the skb is a fragment and reassembly happens before such function call returns, the sk must not be released. This affects skb fragments reassembled via netfilter or similar modules, e.g. openvswitch or ct_act.c, when run as part of tx pipeline. Eric Dumazet made an initial analysis of this bug. Quoting Eric: Calling ip_defrag() in output path is also implying skb_orphan(), which is buggy because output path relies on sk not disappearing. A relevant old patch about the issue was : 8282f27449bf ("inet: frag: Always orphan skbs inside ip_defrag()") [..] net/ipv4/ip_output.c depends on skb->sk being set, and probably to an inet socket, not an arbitrary one. If we orphan the packet in ipvlan, then downstream things like FQ packet scheduler will not work properly. We need to change ip_defrag() to only use skb_orphan() when really needed, ie whenever frag_list is going to be used. Eric suggested to stash sk in fragment queue and made an initial patch. However there is a problem with this: If skb is refragmented again right after, ip_do_fragment() will copy head->sk to the new fragments, and sets up destructor to sock_wfree. IOW, we have no choice but to fix up sk_wmem accouting to reflect the fully reassembled skb, else wmem will underflow. This change moves the orphan down into the core, to last possible moment. As ip_defrag_offset is aliased with sk_buff->sk member, we must move the offset into the FRAG_CB, else skb->sk gets clobbered. This allows to delay the orphaning long enough to learn if the skb has to be queued or if the skb is completing the reasm queue. In the former case, things work as before, skb is orphaned. This is safe because skb gets queued/stolen and won't continue past reasm engine.

While this works, it creates a problem: it forces any MDIO bus properties to also be set on the devices DT node. This mixes the properties of two distinctly different things and is confusing. This change adds support for an optional mdio node to be defined as a child to the device DT node. The child node can then be used to describe MDIO bus properties that the MDIO core can act on when registering the bus. If no mdio child node is found the driver fallback to the old behavior and register the MDIO bus using the device DT node. This change is backward compatible with old bindings in use.

We will replace the garbage collection algorithm for AF_UNIX, where we will consider each inflight AF_UNIX socket as a vertex and its file descriptor as an edge in a directed graph. This patch introduces a new struct unix_vertex representing a vertex in the graph and adds its pointer to struct unix_sock. When we send a fd using the SCM_RIGHTS message, we allocate struct scm_fp_list to struct scm_cookie in scm_fp_copy(). Then, we bump each refcount of the inflight fds' struct file and save them in scm_fp_list.fp. After that, unix_attach_fds() inexplicably clones scm_fp_list of scm_cookie and sets it to skb. (We will remove this part after replacing GC.) Here, we add a new function call in unix_attach_fds() to preallocate struct unix_vertex per inflight AF_UNIX fd and link each vertex to skb's scm_fp_list.vertices. When sendmsg() succeeds later, if the socket of the inflight fd is still not inflight yet, we will set the preallocated vertex to struct unix_sock.vertex and link it to a global list unix_unvisited_vertices under spin_lock(&unix_gc_lock). If the socket is already inflight, we free the preallocated vertex. This is to avoid taking the lock unnecessarily when sendmsg() could fail later. In the following patch, we will similarly allocate another struct per edge, which will finally be linked to the inflight socket's unix_vertex.edges.

As with the previous patch, we preallocate to skb's scm_fp_list an array of struct unix_edge in the number of inflight AF_UNIX fds. There we just preallocate memory and do not use immediately because sendmsg() could fail after this point. The actual use will be in the next patch. When we queue skb with inflight edges, we will set the inflight socket's unix_sock as unix_edge->predecessor and the receiver's unix_sock as successor, and then we will link the edge to the inflight socket's unix_vertex.edges. Note that we set NULL to cloned scm_fp_list.edges in scm_fp_dup() so that MSG_PEEK does not change the shape of the directed graph.

Just before queuing skb with inflight fds, we call scm_stat_add(), which is a good place to set up the preallocated struct unix_vertex and struct unix_edge in UNIXCB(skb).fp. Then, we call unix_add_edges() and construct the directed graph as follows: 1. Set the inflight socket's unix_sock to unix_edge.predecessor. 2. Set the receiver's unix_sock to unix_edge.successor. 3. Set the preallocated vertex to inflight socket's unix_sock.vertex. 4. Link inflight socket's unix_vertex.entry to unix_unvisited_vertices. 5. Link unix_edge.vertex_entry to the inflight socket's unix_vertex.edges. Let's say we pass the fd of AF_UNIX socket A to B and the fd of B to C.

We update them one by one in unix_inflight(), which can be done once in batch. Also, sendmsg() could fail even after unix_inflight(), then we need to acquire unix_gc_lock only to decrement the counters.

The new GC will use a depth first search graph algorithm to find cyclic references. The algorithm visits every vertex exactly once. Here, we implement the DFS part without recursion so that no one can abuse it. unix_walk_scc() marks every vertex unvisited by initialising index as UNIX_VERTEX_INDEX_UNVISITED and iterates inflight vertices in unix_unvisited_vertices and call __unix_walk_scc() to start DFS from an arbitrary vertex. __unix_walk_scc() iterates all edges starting from the vertex and explores the neighbour vertices with DFS using edge_stack. After visiting all neighbours, __unix_walk_scc() moves the visited vertex to unix_visited_vertices so that unix_walk_scc() will not restart DFS from the visited vertex.

From f8b83493b572eca57b98359e92d3ac51b801b32c Mon Sep 17 00:00:00 2001 From: Kuniyuki Iwashima Date: Mon, 25 Mar 2024 13:24:16 -0700 Subject: [PATCH 090/268] af_unix: Detect Strongly Connected Components. In the new GC, we use a simple graph algorithm, Tarjan's Strongly Connected Components (SCC) algorithm, to find cyclic references. The algorithm visits every vertex exactly once using depth-first search (DFS). DFS starts by pushing an input vertex to a stack and assigning it a unique number. Two fields, index and lowlink, are initialised with the number, but lowlink could be updated later during DFS. If a vertex has an edge to an unvisited inflight vertex, we visit it and do the same processing. So, we will have vertices in the stack in the order they appear and number them consecutively in the same order. If a vertex has a back-edge to a visited vertex in the stack, we update the predecessor's lowlink with the successor's index. After iterating edges from the vertex, we check if its index equals its lowlink. If the lowlink is different from the index, it shows there was a back-edge. Then, we go backtracking and propagate the lowlink to its predecessor and resume the previous edge iteration from the next edge. If the lowlink is the same as the index, we pop vertices before and including the vertex from the stack. Then, the set of vertices is SCC, possibly forming a cycle. At the same time, we move the vertices to unix_visited_vertices. When we finish the algorithm, all vertices in each SCC will be linked via unix_vertex.scc_entry. Let's take an example. We have a graph including five inflight vertices (F is not inflight): A -> B -> C -> D -> E (-> F) ^ | `---------' Suppose that we start DFS from C. We will visit C, D, and B first and initialise their index and lowlink. Then, the stack looks like this: > B = (3, 3) (index, lowlink) D = (2, 2) C = (1, 1) When checking B's edge to C, we update B's lowlink with C's index and propagate it to D. B = (3, 1) (index, lowlink) > D = (2, 1) C = (1, 1) Next, we visit E, which has no edge to an inflight vertex. > E = (4, 4) (index, lowlink) B = (3, 1) D = (2, 1) C = (1, 1) When we leave from E, its index and lowlink are the same, so we pop E from the stack as single-vertex SCC. Next, we leave from B and D but do nothing because their lowlink are different from their index. B = (3, 1) (index, lowlink) D = (2, 1) > C = (1, 1) Then, we leave from C, whose index and lowlink are the same, so we pop B, D and C as SCC. Last, we do DFS for the rest of vertices, A, which is also a single-vertex SCC. Finally, each unix_vertex.scc_entry is linked as follows: A -. B -> C -> D E -. ^ | ^ | ^ | `--' `---------' `--' We use SCC later to decide whether we can garbage-collect the sockets. Note that we still cannot detect SCC properly if an edge points to an embryo socket. The following two patches will sort it out.

To garbage collect inflight AF_UNIX sockets, we must define the cyclic reference appropriately. This is a bit tricky if the loop consists of embryo sockets. Suppose that the fd of AF_UNIX socket A is passed to D and the fd B to C and that C and D are embryo sockets of A and B, respectively. It may appear that there are two separate graphs, A (-> D) and B (-> C), but this is not correct. A --. .-- B X C <-' `-> D Now, D holds A's refcount, and C has B's refcount, so unix_release() will never be called for A and B when we close() them. However, no one can call close() for D and C to free skbs holding refcounts of A and B because C/D is in A/B's receive queue, which should have been purged by unix_release() for A and B. So, here's another type of cyclic reference. When a fd of an AF_UNIX socket is passed to an embryo socket, the reference is indirectly held by its parent listening socket. .-> A .-> B | `- sk_receive_queue | `- sk_receive_queue | `- skb | `- skb | `- sk == C | `- sk == D | `- sk_receive_queue | `- sk_receive_queue | `- skb +---------' `- skb +-. | | `---------------------------------------------------------' Technically, the graph must be denoted as A <-> B instead of A (-> D) and B (-> C) to find such a cyclic reference without touching each socket's receive queue. .-> A --. .-- B <-. | X | == A <-> B `-- C <-' `-> D --' We apply this fixup during GC by fetching the real successor by unix_edge_successor(). When we call accept(), we clear unix_sock.listener under unix_gc_lock not to confuse GC.

Before starting Tarjan's algorithm, we need to mark all vertices as unvisited. We can save this O(n) setup by reserving two special indices (0, 1) and using two variables. The first time we link a vertex to unix_unvisited_vertices, we set unix_vertex_unvisited_index to index. During DFS, we can see that the index of unvisited vertices is the same as unix_vertex_unvisited_index. When we finalise SCC later, we set unix_vertex_grouped_index to each vertex's index. Then, we can know (i) that the vertex is on the stack if the index of a visited vertex is >= 2 and (ii) that it is not on the stack and belongs to a different SCC if the index is unix_vertex_grouped_index. After the whole algorithm, all indices of vertices are set as unix_vertex_grouped_index. Next time we start DFS, we know that all unvisited vertices have unix_vertex_grouped_index, and we can use unix_vertex_unvisited_index as the not-on-stack marker. To use the same variable in __unix_walk_scc(), we can swap unix_vertex_(grouped|unvisited)_index at the end of Tarjan's algorithm.

We do not need to run GC if there is no possible cyclic reference. We use unix_graph_maybe_cyclic to decide if we should run GC. If a fd of an AF_UNIX socket is passed to an already inflight AF_UNIX socket, they could form a cyclic reference. Then, we set true to unix_graph_maybe_cyclic and later run Tarjan's algorithm to group them into SCC. Once we run Tarjan's algorithm, we are 100% sure whether cyclic references exist or not. If there is no cycle, we set false to unix_graph_maybe_cyclic and can skip the entire garbage collection next time. When finalising SCC, we set true to unix_graph_maybe_cyclic if SCC consists of multiple vertices. Even if SCC is a single vertex, a cycle might exist as self-fd passing. Given the corner case is rare, we detect it by checking all edges of the vertex and set true to unix_graph_maybe_cyclic. With this change, __unix_gc() is just a spin_lock() dance in the normal usage.

Once a cyclic reference is formed, we need to run GC to check if there is dead SCC. However, we do not need to run Tarjan's algorithm if we know that the shape of the inflight graph has not been changed. If an edge is added/updated/deleted and the edge's successor is inflight, we set false to unix_graph_grouped, which means we need to re-classify SCC. Once we finalise SCC, we set true to unix_graph_grouped. While unix_graph_grouped is true, we can iterate the grouped SCC using vertex->scc_entry in unix_walk_scc_fast(). list_add() and list_for_each_entry_reverse() uses seem weird, but they are to keep the vertex order consistent and make writing test easier.

The definition of the lowlink in Tarjan's algorithm is the smallest index of a vertex that is reachable with at most one back-edge in SCC. This is not useful for a cross-edge. If we start traversing from A in the following graph, the final lowlink of D is 3. The cross-edge here is one between D and C. A -> B -> D D = (4, 3) (index, lowlink) ^ | | C = (3, 1) | V | B = (2, 1) `--- C <--' A = (1, 1) This is because the lowlink of D is updated with the index of C. In the following patch, we detect a dead SCC by checking two conditions for each vertex. 1) vertex has no edge directed to another SCC (no bridge) 2) vertex's out_degree is the same as the refcount of its file If 1) is false, there is a receiver of all fds of the SCC and its ancestor SCC. To evaluate 1), we need to assign a unique index to each SCC and assign it to all vertices in the SCC. This patch changes the lowlink update logic for cross-edge so that in the example above, the lowlink of D is updated with the lowlink of C. A -> B -> D D = (4, 1) (index, lowlink) ^ | | C = (3, 1) | V | B = (2, 1) `--- C <--' A = (1, 1) Then, all vertices in the same SCC have the same lowlink, and we can quickly find the bridge connecting to different SCC if exists. However, it is no longer called lowlink, so we rename it to scc_index. (It's sometimes called lowpoint.) Also, we add a global variable to hold the last index used in DFS so that we do not reset the initial index in each DFS. This patch can be squashed to the SCC detection patch but is split deliberately for anyone wondering why lowlink is not used as used in the original Tarjan's algorithm and many reference implementations.

This patch adds test cases to verify the new GC. We run each test for the following cases: * SOCK_DGRAM * SOCK_STREAM without embryo socket * SOCK_STREAM without embryo socket + MSG_OOB * SOCK_STREAM with embryo sockets * SOCK_STREAM with embryo sockets + MSG_OOB Before and after running each test case, we ensure that there is no AF_UNIX socket left in the netns by reading /proc/net/protocols. We cannot use /proc/net/unix and UNIX_DIAG because the embryo socket does not show up there. Each test creates multiple sockets in an array. We pass sockets in the even index using the peer sockets in the odd index. So, send_fd(0, 1) actually sends fd[0] to fd[2] via fd[0 + 1].

Previously in switchdev mode, PF VSI received missed packets, but only ones marked as Rx. Now it is receiving all missed packets. To queue rule per PR isn't needed, because we use PF VSI instead of control VSI now, and it's already correctly configured. Add flag to correctly set LAN_EN bit in default Tx rule. It shouldn't allow packet to go outside when there is a match.

If it is set try to find correct port representor. Do it based on src_vsi value stored in flex descriptor. Ids of representor pointers stored in xarray are equal to corresponding src_vsi value. Thanks to that we can directly get correct representor if we have src_vsi value. Set multidev flag during ring configuration. If the mode is switchdev, change the ring descriptor to the one that contains src_vsi value. PF netdev should be reconfigured, do it by calling ice_down() and ice_up() if the netdev was up before configuring switchdev.

IMHO it's common when using skip_sw, to use it on all rules. So if all filters in a block is skip_sw filters, then we can bail early, we can thus avoid having to match the filters, just to check for the skip_sw flag. This patch adds a bypass, for when only TC skip_sw rules are used. The bypass is guarded by a static key, to avoid harming other workloads. There are 3 ways that a packet from a skip_sw ruleset, can end up in the kernel path. Although the send packets to a non-existent chain way is only improved a few percents, then I believe it's worth optimizing the trap and fall-though use-cases. +----------------------------+--------+--------+--------+ | Test description | Pre- | Post- | Rel. | | | kpps | kpps | chg. | +----------------------------+--------+--------+--------+ | basic forwarding + notrack | 3589.3 | 3587.9 | 1.00x | | switch to eswitch mode | 3081.8 | 3094.7 | 1.00x | | add ingress qdisc | 3042.9 | 3063.6 | 1.01x | | tc forward in hw / skip_sw |37024.7 |37028.4 | 1.00x | | tc forward in sw / skip_hw | 3245.0 | 3245.3 | 1.00x | +----------------------------+--------+--------+--------+ | tests with only skip_sw rules below: | +----------------------------+--------+--------+--------+ | 1 non-matching rule | 2694.7 | 3058.7 | 1.14x | | 1 n-m rule, match trap | 2611.2 | 3323.1 | 1.27x | | 1 n-m rule, goto non-chain | 2886.8 | 2945.9 | 1.02x | | 5 non-matching rules | 1958.2 | 3061.3 | 1.56x | | 5 n-m rules, match trap | 1911.9 | 3327.0 | 1.74x | | 5 n-m rules, goto non-chain| 2883.1 | 2947.5 | 1.02x | | 10 non-matching rules | 1466.3 | 3062.8 | 2.09x | | 10 n-m rules, match trap | 1444.3 | 3317.9 | 2.30x | | 10 n-m rules,goto non-chain| 2883.1 | 2939.5 | 1.02x | | 25 non-matching rules | 838.5 | 3058.9 | 3.65x | | 25 n-m rules, match trap | 824.5 | 3323.0 | 4.03x | | 25 n-m rules,goto non-chain| 2875.8 | 2944.7 | 1.02x | | 50 non-matching rules | 488.1 | 3054.7 | 6.26x | | 50 n-m rules, match trap | 484.9 | 3318.5 | 6.84x | | 50 n-m rules,goto non-chain| 2884.1 | 2939.7 | 1.02x | +----------------------------+--------+--------+--------+ perf top (25 n-m skip_sw rules - pre patch): 20.39% [kernel] [k] __skb_flow_dissect 16.43% [kernel] [k] rhashtable_jhash2 10.58% [kernel] [k] fl_classify 10.23% [kernel] [k] fl_mask_lookup 4.79% [kernel] [k] memset_orig 2.58% [kernel] [k] tcf_classify 1.47% [kernel] [k] __x86_indirect_thunk_rax 1.42% [kernel] [k] __dev_queue_xmit 1.36% [kernel] [k] nft_do_chain 1.21% [kernel] [k] __rcu_read_lock perf top (25 n-m skip_sw rules - post patch): 5.12% [kernel] [k] __dev_queue_xmit 4.77% [kernel] [k] nft_do_chain 3.65% [kernel] [k] dev_gro_receive 3.41% [kernel] [k] check_preemption_disabled 3.14% [kernel] [k] mlx5e_skb_from_cqe_mpwrq_nonlinear 2.88% [kernel] [k] __netif_receive_skb_core.constprop.0 2.49% [kernel] [k] mlx5e_xmit 2.15% [kernel] [k] ip_forward 1.95% [kernel] [k] mlx5e_tc_restore_tunnel 1.92% [kernel] [k] vlan_gro_receive Test setup: DUT: Intel Xeon D-1518 (2.20GHz) w/ Nvidia/Mellanox ConnectX-6 Dx 2x100G Data rate measured on switch (Extreme X690), and DUT connected as a router on a stick, with pktgen and pktsink as VLANs.

However, the driver's stop() method will only execute if networking interface configuration logic within the Linux distribution has been setup to do so. If shutdown() executes but stop() does not execute, NAPI remains enabled and this can lead to an exception if NAPI is scheduled while the hardware interface has only been partially deinitialized. The networking interface managed by the mlxbf_gige driver must be properly stopped during system shutdown so that IFF_UP is cleared, the hardware interface is put into a clean state, and NAPI is fully deinitialized.

The driver will keep track of the remaining time before timeout and will pass this value to bnxt_hwrm_port_ts_query(). The firmware supports timeout values up to 65535 usecs. If the timeout value passed to bnxt_hwrm_port_ts_query() is less than the FW max value, we will use that value to precisely control the specified timeout. If it is larger than the FW max value, we will use the FW max value and any additional retry to reach the desired timeout will be done in the context of bnxt_ptp_ts_aux_eork().

When supporting additional RSS contexts in subsequent patches, we'll pass the valid rss_ctx to these 2 functions.

Subsequently, f32a21376573 ("ethtool: runtime-resume netdev parent before ethtool ioctl ops") added pm_runtime_get_sync() in the dev_ethtool() path, so the device is resumed before *any* ethtool_ops callback, as it was before 3ef672ab1862. Remove most runtime resumes from ethtool_ops, which are now redundant because the resume has already been done by dev_ethtool(). This is essentially a revert of 3ef672ab1862 ("e1000e: ethtool unnecessarily takes device out of RPM suspend"). There are a couple subtleties: - Prior to 3ef672ab1862, the device was resumed only for the duration of a single ethtool callback. 3ef672ab1862 changed e1000_set_phys_id() so the device was resumed for ETHTOOL_ID_ACTIVE and remained resumed until a subsequent callback for ETHTOOL_ID_INACTIVE. Preserve that part of 3ef672ab1862 so the device will not be runtime suspended while in the ETHTOOL_ID_ACTIVE state. - 3ef672ab1862 added "if (!pm_runtime_suspended())" in before reading the STATUS register in e1000_get_settings(). This was racy and is now unnecessary because dev_ethtool() has resumed the device already, so revert that.

If such packets might land in a tunnel this can cause various issues and udp_gro_receive makes sure this isn't the case by looking for a matching socket. This is performed in udp4/6_gro_lookup_skb but only in the current netns. This is an issue with tunneled packets when the endpoint is in another netns. In such cases the packets will be GROed at the UDP level, which leads to various issues later on. The same thing can happen with rx-gro-list. We saw this with geneve packets being GROed at the UDP level. In such case gso_size is set; later the packet goes through the geneve rx path, the geneve header is pulled, the offset are adjusted and frag_list skbs are not adjusted with regard to geneve. When those skbs hit skb_fragment, it will misbehave. Different outcomes are possible depending on what the GROed skbs look like; from corrupted packets to kernel crashes. One example is a BUG_ON[1] triggered in skb_segment while processing the frag_list. Because gso_size is wrong (geneve header was pulled) skb_segment thinks there is "geneve header size" of data in frag_list, although it's in fact the next packet. The BUG_ON itself has nothing to do with the issue. This is only one of the potential issues. Looking up for a matching socket in udp_gro_receive is fragile: the lookup could be extended to all netns (not speaking about performances) but nothing prevents those packets from being modified in between and we could still not find a matching socket. It's OK to keep the current logic there as it should cover most cases but we also need to make sure we handle tunnel packets being GROed too early.

However this is an issue for CHECKSUM_PARTIAL packets as they can be looped in an egress path and then their partial checksums are not fixed. Different issues can be observed, from invalid checksum on packets to traces like: gen01: hw csum failure skb len=3008 headroom=160 headlen=1376 tailroom=0 mac=(106,14) net=(120,40) trans=160 shinfo(txflags=0 nr_frags=0 gso(size=0 type=0 segs=0)) csum(0xffff232e ip_summed=2 complete_sw=0 valid=0 level=0) hash(0x77e3d716 sw=1 l4=1) proto=0x86dd pkttype=0 iif=12 ... Fix this by only converting CHECKSUM_NONE packets to CHECKSUM_UNNECESSARY by reusing __skb_incr_checksum_unnecessary.

Previous commits have fixed issues when UDP tunnel packets come from a remote host, but if those packets are issued locally they could run into checksum issues. If the inner packet has a partial checksum the information will be lost in the GRO logic, either in udp4/6_gro_complete or in udp_gro_complete_segment and packets will have an invalid checksum when leaving the host. Prevent local UDP tunnel packets from ever being GROed at the outer UDP level. Due to skb->encapsulation being wrongly used in some drivers this is actually only preventing UDP tunnel packets with a partial checksum to be GROed (see iptunnel_handle_offloads) but those were also the packets triggering issues so in practice this should be sufficient.

This can cause issues in two cases: 1. The clock signal hasn't been started yet by the time the MAC driver initializes its hardware. This can make the initialization fail, as in the case of the rzn1 GMAC1 driver. 2. The clock signal is cut during a power saving event. By the time the MAC is brought back up, the clock signal is still not active since phylink_start hasn't been called yet. This brings us back to case 1.

On the other hand, create_flow_handle tries hard to find and reference already existing identical rules instead of creating new ones. These two behaviors can result in a situation where create_flow_handle 1) creates a new rule and references it, then 2) in a subsequent step during the same handle creation references it again, resulting in a rule with a refcount of 2 that is not linked into the tree, will have a NULL parent and root and will result in a crash when the flow group is deleted because del_sw_hw_rule, invoked on rule deletion, assumes node->parent is != NULL. This happened in the wild, due to another bug related to incorrect handling of duplicate pkt_reformat ids, which lead to the code in create_flow_handle incorrectly referencing a just-added rule in the same flow handle, resulting in the problem described above. Full details are at [1]. This patch changes add_rule_fg to add new rules without parents into the tree, properly initializing them and avoiding the crash. This makes it more consistent with how rules are added to an FTE in create_flow_handle.

Using id directly in that case is incorrect, as it maps to the least significant 32 bits of the 64-bit pointer in mlx5_fs_dr_action and not to the pkt reformat id allocated in firmware. For the purpose of comparing whether two rules are identical, interpreting the least significant 32 bits of the mlx5_fs_dr_action pointer as an id mostly works... until it breaks horribly and produces the outcome described in [1]. This patch fixes mlx5_flow_dests_cmp to correctly compare ids using mlx5_fs_dr_action_get_pkt_reformat_id for the SW-managed rules.

In certain situation when busy-loop is enabled together with adaptive coalescing, the driver occasionally misses that there are outstanding descriptors to clean when exiting busy poll. Try to catch the remaining work by triggering a software interrupt when exiting busy poll. No extra interrupts will be generated when busy polling is not used. The issue was found when running sockperf ping-pong tcp test with adaptive coalescing and busy poll enabled (50 as value busy_pool and busy_read sysctl knobs) and results in huge latency spikes with more than 100000us. The fix is inspired from the ice driver and do the following: 1) During napi poll exit in case of busy-poll (napo_complete_done() returns false) this is recorded to q_vector that we were in busy loop. 2) Extends i40e_buildreg_itr() to be able to add an enforced software interrupt into built value 2) In i40e_update_enable_itr() enforces a software interrupt trigger if we are exiting busy poll to catch any pending clean-ups 3) Reuses unused 3rd ITR (interrupt throttle) index and set it to 20K interrupts per second to limit the number of these sw interrupts.

The overlap between net/forwarding/lib.sh and forwarding.config.sample is especially large. This duplication is a potential source of confusion and problems. It would be overall less error prone if each variable were defined in one place only. In this patch set, that place is the library itself. Therefore move all comments from forwarding.config.sample to net/forwarding/lib.sh. Move over also a definition of TC_FLAG, which was missing from lib.sh entirely. Additionally, add to lib.sh a default definition of the topology variables. The logic behind this is that forgetting to specify forwarding.config was a frequent source of frustration for the selftest users. But really, most of the time the default veth based topology is just fine. We considered just sourcing forwarding.config.sample instead if forwarding.config is not available, but this is a cleaner solution. That means the syntax of the forwarding.config.sample override has to change to an array assignment, so that the whole variable is overwritten, not just individual keys, which could leave the value of some keys unchanged. Do the same in lib.sh for any cut'n'pasters out there. The config file is then given a sort of carte blanche to redefine whatever variables it sees fit from the libraries. This is described in a comment in the file. Only a handful of variables are left behind, to illustrate the customization. The fact that the variables are now missing from forwarding.config.sample, and therefore would miss from forwarding.config derived from that file as well, should not change anything. This is just the sample file. Users that keep their own forwarding.config would retain it as before. The only observable change is introduction of TC_FLAG to lib.sh, because now the filters would not be attempted to install to HW datapath. For veth pairs this does not change anything. For HW deployments, users presumably have forwarding.config with this value overridden.

There are however several tests that, while not depending on any HW in particular, nevertheless depend on being used on HW interfaces. Placing these selftests to net/forwarding is confusing, because the selftest will just report it can't be run on veth pairs. At the same time, placing them to a particular driver's selftests subdirectory would be wrong. Instead, add a new directory, drivers/net/hw, where these generic but HW independent selftests should be placed. Move over several such tests including one helper library. Since typically these tests will not be expected to run, omit the directory drivers/net/hw from the TARGETS list in selftests/Makefile. Retain a Makefile in the new directory itself, so that a user can make -C into that directory and act on those tests explicitly.

Currently it works in binary fashion: zero means everything is fine, non-zero means something failed. log_test() then uses the value to given a human-readable message. In order to allow log_test() to report skips and xfails, the semantics of RET need to be more fine-grained. Therefore have RET value be one of kselftest framework constants: $ksft_fail, $ksft_xfail, etc. The current logic in check_err() is such that first non-zero value of RET trumps all those that follow. But that is not right when RET has more fine-grained value semantics. Different outcomes have different weights. The results of PASS and XFAIL are mostly the same: they both communicate a test that did not go wrong. SKIP communicates lack of tooling, which the user should go and try to fix, and as such should not be overridden by the passes. So far, the higher-numbered statuses can be considered weightier. But FAIL should be the weightiest. Add a helper, ksft_status_merge(), which merges two statuses in a way that respects the above conditions. Express it in a generic manner, because exit status merge is subtly different, and we want to reuse the same logic. Use the new helper when setting RET in check_err(). Re-express check_fail() in terms of check_err() to avoid duplication.

Then have EXIT_STATUS track the RET value of the current test. This differs subtly from the way RET tracks the value: while for RET we want to recognize XFAIL as a separate status, for purposes of exit code, we want to to conflate XFAIL and PASS, because they both communicate non-failure. Thus add a new helper, ksft_exit_status_merge(). With this log_test_skip() and log_test_xfail() can be reexpressed as thin wrappers around log_test.

These tests will not run well on a slow machine, be it one with heavy debug kernel, or a VM, or e.g. a single-board computer. Allow users to specify an environment variable, KSFT_MACHINE_SLOW=yes, to indicate that the tests are being run on one such machine. Performance sensitive tests can then use a new helper, xfail_on_slow(), to mark parts of the test that are sensitive to low-performance machines. The helper can be used to just mark the whole suite, like so: xfail_on_slow tests_run ... or, on the other side of the granularity spectrum, to override individual checks: xfail_on_slow check_err $?

But kernel networking CI interprets skips as a sign that tooling is missing, and prompts maintainer investigation. Lack of capability to pass a test should be expressed as XFAIL. Selftests that require HW should normally be put in drivers/net/hw, but doing so for the NH counter selftests would just lead to a lot of duplicity. So instead, introduce a helper, xfail_on_veth(), which can be used to mark selftests that should XFAIL instead of FAILing when run on a veth topology. On non-veth topology, they don't do anything. Use the helper in the HW-stats part of router_mpath_nh_lib selftest.

Commit 5e07e672412b ("tcp: Use bhash2 for v4-mapped-v6 non-wildcard address.") introduced bind() regression for v4-mapped-v6 address. When we bind() the following two addresses on the same port, the 2nd bind() should succeed but fails now. 1. [::] w/ IPV6_ONLY 2. ::ffff:127.0.0.1 After the chagne, v4-mapped-v6 uses bhash2 instead of bhash to detect conflict faster, but I forgot to add a necessary change. During the 2nd bind(), inet_bind2_bucket_match_addr_any() returns the tb2 bucket of [::], and inet_bhash2_conflict() finally calls inet_bind_conflict(), which returns true, meaning conflict. inet_bhash2_addr_any_conflict |- inet_bind2_bucket_match_addr_any <-- return [::] bucket `- inet_bhash2_conflict `- __inet_bhash2_conflict <-- checks IPV6_ONLY for AF_INET | but not for v4-mapped-v6 address `- inet_bind_conflict <-- does not check address inet_bind_conflict() does not check socket addresses because __inet_bhash2_conflict() is expected to do so. However, it checks IPV6_V6ONLY attribute only against AF_INET socket, and not for v4-mapped-v6 address. As a result, v4-mapped-v6 address conflicts with v6-only wildcard address. To avoid that, let's add the missing test to use bhash2 for v4-mapped-v6 address. Fixes: 5e07e672412b ("tcp: Use bhash2 for v4-mapped-v6 non-wildcard address.")

Jianguo Wu reported another bind() regression introduced by bhash2. Calling bind() for the following 3 addresses on the same port, the 3rd one should fail but now succeeds. 1. 0.0.0.0 or ::ffff:0.0.0.0 2. [::] w/ IPV6_V6ONLY 3. IPv4 non-wildcard address or v4-mapped-v6 non-wildcard address The first two bind() create tb2 like this: bhash2 -> tb2(:: w/ IPV6_V6ONLY) -> tb2(0.0.0.0) The 3rd bind() will match with the IPv6 only wildcard address bucket in inet_bind2_bucket_match_addr_any(), however, no conflicting socket exists in the bucket. So, inet_bhash2_conflict() will returns false, and thus, inet_bhash2_addr_any_conflict() returns false consequently. As a result, the 3rd bind() bypasses conflict check, which should be done against the IPv4 wildcard address bucket. So, in inet_bhash2_addr_any_conflict(), we must iterate over all buckets. Note that we cannot add ipv6_only flag for inet_bind2_bucket as it would confuse the following patetrn. 1. [::] w/ SO_REUSE{ADDR,PORT} and IPV6_V6ONLY 2. [::] w/ SO_REUSE{ADDR,PORT} 3. IPv4 non-wildcard address or v4-mapped-v6 non-wildcard address The first bind() would create a bucket with ipv6_only flag true, the second bind() would add the [::] socket into the same bucket, and the third bind() could succeed based on the wrong assumption that ipv6_only bucket would not conflict with v4(-mapped-v6) address.

Also, the two bind() calls are swapped to cover various patterns how bind buckets are created. However, only testing two addresses is insufficient to detect regression. So, we will add more bind() calls, and then, we need to define different errno for each bind() per test case. As a prepartion, let's define the reverse order bind() test cases as fixtures.

This patch adds two tests using SO_REUSEADDR and SO_REUSEPORT and defines errno for each test case. SO_REUSEADDR/SO_REUSEPORT is set for the per-fixture two bind() calls. The notable pattern is the pair of v6only [::] and plain [::]. The two sockets are put into the same tb2, where per-bucket v6only flag would be useless to detect bind() conflict.

This is a NAPI function, so GFP_ATOMIC is implied. The only practical choice the caller has is whether to set __GFP_NOWARN. But that's a false choice, too, allocation failures in atomic context will happen, and printing warnings in logs, effectively for a packet drop, is both too much and very likely non-actionable. This leads me to a conclusion that most uses of napi_alloc_skb() are simply misguided, and should use __GFP_NOWARN in the first place. We also have a "standard" way of reporting allocation failures via the queue stat API (qstats::rx-alloc-fail). The direct motivation for this patch is that one of the drivers used at Meta calls napi_alloc_skb() (so prior to this patch without __GFP_NOWARN), and the resulting OOM warning is the top networking warning in our fleet.

This mechanism is responsible for triggering errata i2401: "CPSW: Host Timestamps Cause CPSW Port to Lock up" To prevent port lock up, disable TSTAMP_EN bit in CPTS_CONTROL register.

There are 10 structures with flexible arrays at the end, but 9 of them has flex member counter in Little Endian. Make the code a bit more robust by applying __counted_by_le() to those 9. LE platforms is the main target for this driver, so they would receive additional protection. While we're here, add __counted_by() to virtchnl2_ptype::proto_id, as its counter is `u8` regardless of the Endianness.

However, during the round of replacement if-__set-else-__clear with __assign_bit() as per Andy's advice, bloat-o-meter showed +1024 bytes difference in object code size for one module (even one function), where the pattern: DECLARE_BITMAP(foo) = { }; // on the stack, zeroed if (a) __set_bit(const_bit_num, foo); if (b) __set_bit(another_const_bit_num, foo); ... is heavily used, although there should be no difference: the bitmap is zeroed, so the second half of __assign_bit() should be compiled-out as a no-op. I either missed the fact that __assign_bit() has bitmap pointer marked as `volatile` (as we usually do for bitops) or was hoping that the compilers would at least try to look past the `volatile` for __always_inline functions. Anyhow, due to that attribute, the compilers were always compiling the whole expression and no mentioned compile-time optimizations were working. Convert __assign_bit() to a macro since it's a very simple if-else and all of the checks are performed inside __set_bit() and __clear_bit(), thus that wrapper has to be as transparent as possible. After that change, despite it showing only -20 bytes change for vmlinux (due to that it's still relatively unpopular), no drastic code size changes happen when replacing if-set-else-clear for onstack bitmaps with __assign_bit(), meaning the compiler now expands them to the actual operations will all the expected optimizations. Atomic assign_bit() is less affected due to its nature, but let's convert it to a macro as well to keep the code consistent and not leave a place for possible suboptimal codegen.

Unfortunately, turned out that passing `volatile` to those macros discards any possibility of optimization, as the compilers then don't even try to look whether the passed bitmap is known at compilation time. In addition to that, the mentioned linkmode helpers are marked with `inline`, not `__always_inline`, meaning that it's not guaranteed some compiler won't uninline them for no reason, which will also effectively prevent them from being optimized (it's a well-known thing the compilers sometimes uninline `2 + 2`). Convert linkmode_*_bit() from inlines to macros. Their calling convention are 1:1 with the corresponding bitops, so that it's not even needed to enumerate and map the arguments, only the names. No changes in vmlinux' object code (compiled by LLVM for x86_64) whatsoever, but that doesn't necessarily means the change is meaningless.

Some generic helper is long overdue. Add one, bitmap_size(), but with one detail. BITS_TO_LONGS() uses DIV_ROUND_UP(). The latter works well when both divident and divisor are compile-time constants or when the divisor is not a pow-of-2. When it is however, the compilers sometimes tend to generate suboptimal code (GCC 13): 48 83 c0 3f add $0x3f,%rax 48 c1 e8 06 shr $0x6,%rax 48 8d 14 c5 00 00 00 00 lea 0x0(,%rax,8),%rdx %BITS_PER_LONG is always a pow-2 (either 32 or 64), but GCC still does full division of `nbits + 63` by it and then multiplication by 8. Instead of BITS_TO_LONGS(), use ALIGN() and then divide by 8. GCC: 8d 50 3f lea 0x3f(%rax),%edx c1 ea 03 shr $0x3,%edx 81 e2 f8 ff ff 1f and $0x1ffffff8,%edx Now it shifts `nbits + 63` by 3 positions (IOW performs fast division by 8) and then masks bits[2:0]. bloat-o-meter: add/remove: 0/0 grow/shrink: 20/133 up/down: 156/-773 (-617) Clang does it better and generates the same code before/after starting from -O1, except that with the ALIGN() approach it uses %edx and thus still saves some bytes: add/remove: 0/0 grow/shrink: 9/133 up/down: 18/-538 (-520) Note that we can't expand DIV_ROUND_UP() by adding a check and using this approach there, as it's used in array declarations where expressions are not allowed. Add this helper to tools/ as well.

Now all of those 16 bits are occupied and there's no more free space for new flags. It can't be simply switched to a bigger container with no adjustments to the values, since it's an explicit Endian storage, and on LE systems (__be16)0x0001 equals to (__be64)0x0001000000000000. We could probably define new 64-bit flags depending on the Endianness, i.e. (__be64)0x0001 on BE and (__be64)0x00010000... on LE, but that would introduce an Endianness dependency and spawn a ton of Sparse warnings. To mitigate them, all of those places which were adjusted with this change would be touched anyway, so why not define stuff properly if there's no choice. Define IP_TUNNEL_*_BIT counterparts as a bit number instead of the value already coded and a fistful of <16 <-> bitmap> converters and helpers. The two flags which have a different bit position are SIT_ISATAP_BIT and VTI_ISVTI_BIT, as they were defined not as __cpu_to_be16(), but as (__force __be16), i.e. had different positions on LE and BE. Now they both have strongly defined places. Change all __be16 fields which were used to store those flags, to IP_TUNNEL_DECLARE_FLAGS() -> DECLARE_BITMAP(__IP_TUNNEL_FLAG_NUM) -> unsigned long[1] for now, and replace all TUNNEL_* occurrences to their bitmap counterparts. Use the converters in the places which talk to the userspace, hardware (NFP) or other hosts (GRE header). The rest must explicitly use the new flags only. This must be done at once, otherwise there will be too many conversions throughout the code in the intermediate commits. Finally, disable the old __be16 flags for use in the kernel code (except for the two 'irregular' flags mentioned above), to prevent any accidental (mis)use of them. For the userspace, nothing is changed, only additions were made. Most noticeable bloat-o-meter difference (.text): vmlinux: 307/-1 (306) gre.ko: 62/0 (62) ip_gre.ko: 941/-217 (724) [*] ip_tunnel.ko: 390/-900 (-510) [**] ip_vti.ko: 138/0 (138) ip6_gre.ko: 534/-18 (516) [*] ip6_tunnel.ko: 118/-10 (108) [*] gre_flags_to_tnl_flags() grew, but still is inlined [**] ip_tunnel_find() got uninlined, hence such decrease The average code size increase in non-extreme case is 100-200 bytes per module, mostly due to sizeof(long) > sizeof(__be16), as %__IP_TUNNEL_FLAG_NUM is less than %BITS_PER_LONG and the compilers are able to expand the majority of bitmap_*() calls here into direct operations on scalars.

The helpers are all inline, so no dependencies on the related CONFIG_* (or a standalone module) are needed. Cover three possible cases: 1. No bits past BIT(15) are set, VTI/SIT bits are not set. This conversion is almost a direct assignment. 2. No bits past BIT(15) are set, but VTI/SIT bit is set. During the conversion, it must be transformed into BIT(16) in the bitmap, but still compatible with the __be16 format. 3. The bitmap has bits past BIT(15) set (not the VTI/SIT one). The result will be truncated. Note that currently __IP_TUNNEL_FLAG_NUM is 17 (incl. special), which means that the result of this case is currently semi-false-positive.

It is specified in TS 29.244[1]. Note that this module is not designed to support this Protocol in the kernel space. There is no support for parsing any PFCP messages. There is no API that could be used by any userspace daemon. Basically it does not support PFCP. This protocol is sophisticated and there is no need for implementing it in the kernel. The purpose of this module is to allow users to setup software and hardware offload of PFCP packets using tc tool. When user requests to create a PFCP device, a new socket is created. The socket is set up with port number 8805 which is specific for PFCP [29.244 4.2.2]. This allow to receive PFCP request messages, response messages use other ports. Note that only one PFCP netdev can be created. Only IPv4 is supported at this time.

Rename ICE_TC_FLWR_FIELD_ENC_OPTS to ICE_TC_FLWR_FIELD_GTP_OPTS and check for tunnel type earlier. After this refactor, it is easier to add new headers using FLOW_DISSECTOR_KEY_ENC_OPTS - instead of checking tunnel type in ice_tc_count_lkups() and ice_tc_fill_tunnel_outer(), it needs to be checked only once, in ice_parse_tunnel_attr().

This issue happens sporadically and in most cases a second access to the PHY via the MDIO interface results in success. As a workaround, introduce a retry counter which is set to 3 on Meteor Lake systems. The driver will only return an error if 3 consecutive PHY access attempts fail. The retry mechanism is disabled in specific flows, where MDI errors are expected.

Separating this configuration from the ULP enabling flow and moving it to the shutdown function allows enough time for the interface to settle and avoids adding a delay.

This matters at least on AMD Zen1-4 platforms (see SRSO) This might be because rcu_read_lock() and rcu_read_unlock() are no longer nops in recent kernels ? Add sk_wake_async_rcu() variant, which must be called from contexts already holding rcu lock. As SOCK_FASYNC is deprecated in modern days, use unlikely() to give a hint to the compiler. sk_wake_async_rcu() is properly inlined from __udp_enqueue_schedule_skb() and sock_def_readable().

This is not longer needed and is safe after commit c899710fe7f9 ("networking: Update to register_net_sysctl_sz") added the array size to the ctl_table registration * Replace the for loop stop condition that tests for procname == NULL with one that depends on array size * Removed the "-1" that adjusted for having an extra empty element when looping over ctl_table arrays * Removing the unprivileged user check in ipv6_route_sysctl_init is safe as it is replaced by calling ipv6_route_sysctl_table_size; introduced in commit c899710fe7f9 ("networking: Update to register_net_sysctl_sz") * Replace empty array registration with the register_net_sysctl_sz call.

Functionality that relied on the receive buffer being a compound page broke at that point: The SMC-D protocol, that utilizes the ism device driver, passes receive buffers to the splice processor in a struct splice_pipe_desc with a single entry list of struct pages. As the buffer is no longer a compound page, the splice processor now rejects requests to handle more than a page worth of data. Replace dma_alloc_coherent() and allocate a buffer with kmalloc() then create a DMA map for it with dma_map_page(). Since only receive buffers on ISM devices use DMA, qualify the mapping as FROM_DEVICE. Since ISM devices are available on arch s390, only and on that arch all DMA is coherent, there is no need to introduce and export some kind of dma_sync_to_cpu() method to be called by the SMC-D protocol layer. Analogously, replace dma_free_coherent by a two step dma_unmap_page, then kfree to free the receive buffer.

In situations where the link is not brought up yet and the system suspends the regular PHY power management will run. Since the FEC ETHEREN control bit is cleared (automatically) on suspend the controller is off in resume. When the regular PHY power management resume path runs in this context it will write to the MII_DATA register but nothing will be transmitted on the MDIO bus. This can be observed by the following log: fec 5b040000.ethernet eth0: MDIO read timeout Microchip LAN87xx T1 5b040000.ethernet-1:04: PM: dpm_run_callback(): mdio_bus_phy_resume+0x0/0xc8 returns -110 Microchip LAN87xx T1 5b040000.ethernet-1:04: PM: failed to resume: error -110 The data written will however remain in the MII_DATA register. When the link later is set to administrative up it will trigger a call to fec_restart() which will restore the MII_SPEED register. This triggers the quirk explained in f166f890c8f0 ("net: ethernet: fec: Replace interrupt driven MDIO with polled IO") causing an extra MII_EVENT. This extra event desynchronizes all the MDIO register reads, causing them to complete too early. Leading all reads to read as 0 because fec_enet_mdio_wait() returns too early. When a Microchip LAN8700R PHY is connected to the FEC, the 0 reads causes the PHY to be initialized incorrectly and the PHY will not transmit any ethernet signal in this state. It cannot be brought out of this state without a power cycle of the PHY.
