Vladimir Oltean say: ==================== ethtool support for IEEE 802.3 MAC Merge layer Change log ---------- v3->v4: - add missing opening bracket in ocelot_port_mm_irq() - moved cfg.verify_time range checking so that it actually takes place for the updated rather than old value v3 at: https://patchwork.kernel.org/project/netdevbpf/cover/20230117085947.2176464-1-vladimir.oltean@nxp.com/ v2->v3: - made get_mm return int instead of void - deleted ETHTOOL_A_MM_SUPPORTED - renamed ETHTOOL_A_MM_ADD_FRAG_SIZE to ETHTOOL_A_MM_TX_MIN_FRAG_SIZE - introduced ETHTOOL_A_MM_RX_MIN_FRAG_SIZE - cleaned up documentation - rebased on top of PLCA changes - renamed ETHTOOL_STATS_SRC_* to ETHTOOL_MAC_STATS_SRC_* v2 at: https://patchwork.kernel.org/project/netdevbpf/cover/20230111161706.1465242-1-vladimir.oltean@nxp.com/ v1->v2: I've decided to focus just on the MAC Merge layer for now, which is why I am able to submit this patch set as non-RFC. v1 (RFC) at: https://patchwork.kernel.org/project/netdevbpf/cover/20220816222920.1952936-1-vladimir.oltean@nxp.com/ What is being introduced ------------------------ TL;DR: a MAC Merge layer as defined by IEEE 802.3-2018, clause 99 (interspersing of express traffic). This is controlled through ethtool netlink (ETHTOOL_MSG_MM_GET, ETHTOOL_MSG_MM_SET). The raw ethtool commands are posted here: https://patchwork.kernel.org/project/netdevbpf/cover/20230111153638.1454687-1-vladimir.oltean@nxp.com/ The MAC Merge layer has its own statistics counters (ethtool --include-statistics --show-mm swp0) as well as two member MACs, the statistics of which can be queried individually, through a new ethtool netlink attribute, corresponding to: $ ethtool -I --show-pause eno2 --src aggregate $ ethtool -S eno2 --groups eth-mac eth-phy eth-ctrl rmon -- --src pmac The core properties of the MAC Merge layer are described in great detail in patches 02/12 and 03/12. They can be viewed in "make htmldocs" format. Devices for which the API is supported -------------------------------------- I decided to start with the Ethernet switch on NXP LS1028A (Felix) because of the smaller patch set. I also have support for the ENETC controller pending. I would like to get confirmation that the UAPI being proposed here will not restrict any use cases known by other hardware vendors. Why is support for preemptible traffic classes not here? -------------------------------------------------------- There is legitimate concern whether the 802.1Q portion of the standard (which traffic classes go to the eMAC and which to the pMAC) should be modeled in Linux using tc or using another UAPI. I think that is stalling the entire series, but should be discussed separately instead. Removing FP adminStatus support makes me confident enough to submit this patch set without an RFC tag (meaning: I wouldn't mind if it was merged as is). What is submitted here is sufficient for an LLDP daemon to do its job. I've patched openlldp to advertise and configure frame preemption: https://github.com/vladimiroltean/openlldp/tree/frame-preemption-v3 In case someone wants to try it out, here are some commands I've used. # Configure the interfaces to receive and transmit LLDP Data Units lldptool -L -i eno0 adminStatus=rxtx lldptool -L -i swp0 adminStatus=rxtx # Enable the transmission of certain TLVs on switch's interface lldptool -T -i eno0 -V addEthCap enableTx=yes lldptool -T -i swp0 -V addEthCap enableTx=yes # Query LLDP statistics on switch's interface lldptool -S -i swp0 # Query the received neighbor TLVs lldptool -i swp0 -t -n -V addEthCap Additional Ethernet Capabilities TLV Preemption capability supported Preemption capability enabled Preemption capability active Additional fragment size: 60 octets So using this patch set, lldpad will be able to advertise and configure frame preemption, but still, no data packet will be sent as preemptible over the link, because there is no UAPI to control which traffic classes are sent as preemptible and which as express. Preemptable or preemptible? --------------------------- IEEE 802.3 uses "preemptable" throughout. IEEE 802.1Q uses "preemptible" throughout. Because the definition of "preemptible" falls under 802.1Q's jurisdiction and 802.3 just references it, I went with the 802.1Q naming even where supporting an 802.3 feature. Also, checkpatch agrees with this. ==================== Signed-off-by:

Due to the fact that the kernel-side data structures have been carried over from the ioctl-based ethtool, we are now in the situation where we have an ethnl_update_bool32() function, but the plain function that operates on a boolean value kept in an actual u8 netlink attribute doesn't exist. With new ethtool features that are exposed solely over netlink, the kernel data structures will use the "bool" type, so we will need this kind of helper. Introduce it now; it's needed for things like verify-disabled for the MAC merge configuration. Signed-off-by:

The page_pool_release_page was used when freeing rx buffers, and this function just unmaps the page (if mapped) and does not recycle the page. So after hundreds of down/up the eth0, the system will out of memory. For more details, please refer to the following reproduce steps and bug logs. To solve this issue and refer to the doc of page pool, the page_pool_put_full_page should be used to replace page_pool_release_page. Because this API will try to recycle the page if the page refcnt equal to 1. After testing 20000 times, the issue can not be reproduced anymore (about testing 391 times the issue will occur on i.MX8MN-EVK before). Reproduce steps: Create the test script and run the script. The script content is as follows: LOOPS=20000 i=1 while [ $i -le $LOOPS ] do echo "TINFO:ENET $curface up and down test $i times" org_macaddr=$(cat /sys/class/net/eth0/address) ifconfig eth0 down

Most netlink attributes are parsed and validated from __nla_validate_parse() or validate_nla() u16 type = nla_type(nla); if (type == 0 || type > maxtype) { /* error or continue */ } @type is then used as an array index and can be used as a Spectre v1 gadget. array_index_nospec() can be used to prevent leaking content of kernel memory to malicious users. This should take care of vast majority of netlink uses, but an audit is needed to take care of others where validation is not yet centralized in core netlink functions.

The initial default value of 0 for tp->rate_app_limited was incorrect, since a flow is indeed application-limited until it first sends data.

In the original implementation of dwmac5 commit 8bf993a5 ("net: stmmac: Add support for DWMAC5 and implement Safety Features") all safety features were enabled by default. Later it seems some implementations didn't have support for all the features, so in commit 5ac712dc ("net: stmmac: enable platform specific safety features") the safety_feat_cfg structure was added to the callback and defined for some platforms to selectively enable these safety features. The problem is that only certain platforms were given that software support. If the automotive safety package bit is set in the hardware features register the safety feature callback is called for the platform, and for platforms that didn't get a safety_feat_cfg defined this results in the following NULL pointer dereference: [ 7.933303] Call trace: [ 7.935812] dwmac5_safety_feat_config+0x20/0x170 [stmmac] [ 7.941455] __stmmac_open+0x16c/0x474 [stmmac] [ 7.946117] stmmac_open+0x38/0x70 [stmmac] [ 7.950414] __dev_open+0x100/0x1dc [ 7.954006] __dev_change_flags+0x18c/0x204 [ 7.958297] dev_change_flags+0x24/0x6c [ 7.962237] do_setlink+0x2b8/0xfa4 [ 7.965827] __rtnl_newlink+0x4ec/0x840 [ 7.969766] rtnl_newlink+0x50/0x80 [ 7.973353] rtnetlink_rcv_msg+0x12c/0x374 [ 7.977557] netlink_rcv_skb+0x5c/0x130 [ 7.981500] rtnetlink_rcv+0x18/0x2c [ 7.985172] netlink_unicast+0x2e8/0x340 [ 7.989197] netlink_sendmsg+0x1a8/0x420 [ 7.993222] ____sys_sendmsg+0x218/0x280 [ 7.997249] ___sys_sendmsg+0xac/0x100 [ 8.001103] __sys_sendmsg+0x84/0xe0 [ 8.004776] __arm64_sys_sendmsg+0x24/0x30 [ 8.008983] invoke_syscall+0x48/0x114 [ 8.012840] el0_svc_common.constprop.0+0xcc/0xec [ 8.017665] do_el0_svc+0x38/0xb0 [ 8.021071] el0_svc+0x2c/0x84 [ 8.024212] el0t_64_sync_handler+0xf4/0x120 [ 8.028598] el0t_64_sync+0x190/0x194 Go back to the original behavior, if the automotive safety package is found to be supported in hardware enable all the features unless safety_feat_cfg is passed in saying this particular platform only supports a subset of the features.

ALU table entry 2 register in KSZ9477 have bit positions reserved for forwarding port map. This field is referred in ksz9477_fdb_del() for clearing forward port map and alu table. But current fdb_del refer ALU table entry 3 register for accessing forward port map. Update ksz9477_fdb_del() to get forward port map from correct alu table entry register. With this bug, issue can be observed while deleting static MAC entries. Delete any specific MAC entry using "bridge fdb del" command. This should clear all the specified MAC entries. But it is observed that entries with self static alone are retained. Tested on LAN9370 EVB since ksz9477_fdb_del() is used common across LAN937x and KSZ series.

Avoid race between process wakeup and tpacket_v3 block timeout. The test waits for cfg_timeout_msec for packets to arrive. Packets arrive in tpacket_v3 rings, which pass packets ("frames") to the process in batches ("blocks"). The sk waits for req3.tp_retire_blk_tov msec to release a block. Set the block timeout lower than the process waiting time, else the process may find that no block has been released by the time it scans the socket list. Convert to a ring of more than one, smaller, blocks with shorter timeouts. Blocks must be page aligned, so >= 64KB. Fixes: 5ebfb4cc ("selftests/net: toeplitz test") Signed-off-by:

The referenced commit changed the error code returned by the kernel when preventing a non-established socket from attaching the ktls ULP. Before to such a commit, the user-space got ENOTCONN instead of EINVAL. The existing self-tests depend on such error code, and the change caused a failure: RUN global.non_established ... tls.c:1673:non_established:Expected errno (22) == ENOTCONN (107) non_established: Test failed at step #3 FAIL global.non_established In the unlikely event existing applications do the same, address the issue by restoring the prior error code in the above scenario. Note that the only other ULP performing similar checks at init time - smc_ulp_ops - also fails with ENOTCONN when trying to attach the ULP to a non-established socket. Reported-by:

The commit 4af1b64f ("octeontx2-pf: Fix lmtst ID used in aura free") uses the get/put_cpu() to protect the usage of percpu pointer in ->aura_freeptr() callback, but it also unnecessarily disable the preemption for the blockable memory allocation. The commit 87b93b67 ("octeontx2-pf: Avoid use of GFP_KERNEL in atomic context") tried to fix these sleep inside atomic warnings. But it only fix the one for the non-rt kernel. For the rt kernel, we still get the similar warnings like below.

But there are only two ->aura_freeptr() callbacks, otx2_aura_freeptr() and cn10k_aura_freeptr(). There is no usage of perpcu variable in the otx2_aura_freeptr() at all, so the get/put_cpu() seems redundant to it. We can move the get/put_cpu() into the corresponding callback which really has the percpu variable usage and avoid the sprinkling of get/put_cpu() in several places.

While one cpu is working on looking up the right socket from ehash table, another cpu is done deleting the request socket and is about to add (or is adding) the big socket from the table. It means that we could miss both of them, even though it has little chance. Let me draw a call trace map of the server side.

Why could this be a real problem? This case is happening only when the final ack and the first data receiving by different CPUs. Then the server receiving data with ACK flag tries to search one proper established socket from ehash table, but apparently it fails as my map shows above. After that, the server fetches a listener socket and then sends a RST because it finds a ACK flag in the skb (data), which obeys RST definition in RFC 793. Besides, Eric pointed out there's one more race condition where it handles tw socket hashdance. Only by adding to the tail of the list before deleting the old one can we avoid the race if the reader has already begun the bucket traversal and it would possibly miss the head. Many thanks to Eric for great help from beginning to end. Fixes: 5e0724d0 ("tcp/dccp: fix hashdance race for passive sessions") Suggested-by:

This reverts commit 0aa64df3. Currently IFF_NO_ADDRCONF is used to prevent all ipv6 addrconf for the slave ports of team, bonding and failover devices and it means no ipv6 packets can be sent out through these slave ports. However, for team device, "nsna_ping" link_watch requires ipv6 addrconf. Otherwise, the link will be marked failure. This patch removes the IFF_NO_ADDRCONF flag set for team port, and we will fix the original issue in another patch, as Jakub suggested. Fixes: 0aa64df3 ("net: team: use IFF_NO_ADDRCONF flag to prevent ipv6 addrconf") Signed-off-by:
