2021-11-05net: udp: correct the document for udp_memMenglong Dong1-4/+2
udp_mem is a vector of 3 INTEGERs, which is used to limit the number of pages allowed for queueing by all UDP sockets. However, sk_has_memory_pressure() in __sk_mem_raise_allocated() always return false for udp, as memory pressure is not supported by udp, which means that __sk_mem_raise_allocated() will fail once pages allocated for udp socket exceeds udp_mem[0]. Therefor, udp_mem[0] is the only one that limit the number of pages. However, the document of udp_mem just express that udp_mem[2] is the limitation. So, just fix it.

Eugene Syromiatnikov says: ==================== MCTP sockaddr padding check/initialisation fixup This pair of patches introduces checks for padding fields of struct sockaddr_mctp/sockaddr_mctp_ext to ease their re-use for possible extensions in the future; as well as zeroing of these fields in the respective sockaddr filling routines. While the first commit is definitely an ABI breakage, it is proposed in hopes that the change is made soon enough (the interface appeared only in Linux 5.15) to avoid affecting any existing user space. ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>

As reported by Zhang there's a small issue if in forced mode the duplex mode changes with the link staying up [0]. In this case the MAC isn't notified about the change. The proposed patch relies on the phylib state machine and ignores the fact that there are drivers that uses phylib but not the phylib state machine. So let's don't change the behavior for such drivers and fix it w/o re-adding state PHY_FORCING for the case that phylib state machine is used.

The VF can be configured via the PF's ndo ops at the same time the PF is receiving/handling virtchnl messages. This has many issues, with one of them being the ndo op could be actively resetting a VF (i.e. resetting it to the default state and deleting/re-adding the VF's VSI) while a virtchnl message is being handled. The following error was seen because a VF ndo op was used to change a VF's trust setting while the VIRTCHNL_OP_CONFIG_VSI_QUEUES was ongoing: [35274.192484] ice 0000:88:00.0: Failed to set LAN Tx queue context, error: ICE_ERR_PARAM [35274.193074] ice 0000:88:00.0: VF 0 failed opcode 6, retval: -5 [35274.193640] iavf 0000:88:01.0: PF returned error -5 (IAVF_ERR_PARAM) to our request 6 Fix this by making sure the virtchnl handling and VF ndo ops that trigger VF resets cannot run concurrently. This is done by adding a struct mutex cfg_lock to each VF structure. For VF ndo ops, the mutex will be locked around the critical operations and VFR. Since the ndo ops will trigger a VFR, the virtchnl thread will use mutex_trylock(). This is done because if any other thread (i.e. VF ndo op) has the mutex, then that means the current VF message being handled is no longer valid, so just ignore it.

2021-11-03ice: Fix not stopping Tx queues for VFsBrett Creeley2-5/+3
When a VF is removed and/or reset its Tx queues need to be stopped from the PF. This is done by calling the ice_dis_vf_qs() function, which calls ice_vsi_stop_lan_tx_rings(). Currently ice_dis_vf_qs() is protected by the VF state bit ICE_VF_STATE_QS_ENA. Unfortunately, this is causing the Tx queues to not be disabled in some cases and when the VF tries to re-enable/reconfigure its Tx queues over virtchnl the op is failing. This is because a VF can be reset and/or removed before the ICE_VF_STATE_QS_ENA bit is set, but the Tx queues were already configured via ice_vsi_cfg_single_txq() in the VIRTCHNL_OP_CONFIG_VSI_QUEUES op. However, the ICE_VF_STATE_QS_ENA bit is set on a successful VIRTCHNL_OP_ENABLE_QUEUES, which will always happen after the VIRTCHNL_OP_CONFIG_VSI_QUEUES op. This was causing the following error message when loading the ice driver, creating VFs, and modifying VF trust in an endless loop: [35274.192484] ice 0000:88:00.0: Failed to set LAN Tx queue context, error: ICE_ERR_PARAM [35274.193074] ice 0000:88:00.0: VF 0 failed opcode 6, retval: -5 [35274.193640] iavf 0000:88:01.0: PF returned error -5 (IAVF_ERR_PARAM) to our request 6 Fix this by always calling ice_dis_vf_qs() and silencing the error message in ice_vsi_stop_tx_ring() since the calling code ignores the return anyway. Also, all other places that call ice_vsi_stop_tx_ring() catch the error, so this doesn't affect those flows since there was no change to the values the function returns. Other solutions were considered (i.e. tracking which VF queues had been "started/configured" in VIRTCHNL_OP_CONFIG_VSI_QUEUES, but it seemed more complicated than it was worth. This solution also brings in the chance for other unexpected conditions due to invalid state bit checks. So, the proposed solution seemed like the best option since there is no harm in failing to stop Tx queues that were never started. This issue can be seen using the following commands: for i in {0..50}; do rmmod ice modprobe ice sleep 1 echo 1 > /sys/class/net/ens785f0/device/sriov_numvfs echo 1 > /sys/class/net/ens785f1/device/sriov_numvfs ip link set ens785f1 vf 0 trust on ip link set ens785f0 vf 0 trust on sleep 2 echo 0 > /sys/class/net/ens785f0/device/sriov_numvfs echo 0 > /sys/class/net/ens785f1/device/sriov_numvfs sleep 1 echo 1 > /sys/class/net/ens785f0/device/sriov_numvfs echo 1 > /sys/class/net/ens785f1/device/sriov_numvfs ip link set ens785f1 vf 0 trust on ip link set ens785f0 vf 0 trust on done Fixes: 77ca27c41705 ("ice: add support for virtchnl_queue_select.[tx|rx]_queues bitmap") Signed-off-by: Brett Creeley <[email protected]> Tested-by: Konrad Jankowski <[email protected]> Signed-off-by: Tony Nguyen <[email protected]>

2021-11-03ice: Fix VF true promiscuous modeBrett Creeley2-43/+40
When a VF requests promiscuous mode and it's trusted and true promiscuous mode is enabled the PF driver attempts to enable unicast and/or multicast promiscuous mode filters based on the request. This is fine, but there are a couple issues with the current code. [1] The define to configure the unicast promiscuous mode mask also includes bits to configure the multicast promiscuous mode mask, which causes multicast to be set/cleared unintentionally. [2] All 4 cases for enable/disable unicast/multicast mode are not handled in the promiscuous mode message handler, which causes unexpected results regarding the current promiscuous mode settings. To fix [1] make sure any promiscuous mask defines include the correct bits for each of the promiscuous modes. To fix [2] make sure that all 4 cases are handled since there are 2 bits (FLAG_VF_UNICAST_PROMISC and FLAG_VF_MULTICAST_PROMISC) that can be either set or cleared. Also, since either unicast and/or multicast promiscuous configuration can fail, introduce two separate error values to handle each of these cases.

2021-11-03net: dsa: felix: fix broken VLAN-tagged PTP under VLAN-aware bridgeVladimir Oltean3-6/+7
Normally it is expected that the dsa_device_ops :: rcv() method finishes parsing the DSA tag and consumes it, then never looks at it again. But commit c0bcf537667c ("net: dsa: ocelot: add hardware timestamping support for Felix") added support for RX timestamping in a very unconventional way. On this switch, a partial timestamp is available in the DSA header, but the driver got away with not parsing that timestamp right away, but instead delayed that parsing for a little longer: dsa_switch_rcv(): nskb = cpu_dp->rcv(skb, dev); <------------- not here -> ocelot_rcv() ... skb = nskb; skb_push(skb, ETH_HLEN); skb->pkt_type = PACKET_HOST; skb->protocol = eth_type_trans(skb, skb->dev); ... if (dsa_skb_defer_rx_timestamp(p, skb)) <--- but here -> felix_rxtstamp() return 0; When in felix_rxtstamp(), this driver accounted for the fact that eth_type_trans() happened in the meanwhile, so it got a hold of the extraction header again by subtracting (ETH_HLEN + OCELOT_TAG_LEN) bytes from the current skb->data. This worked for quite some time but was quite fragile from the very beginning. Not to mention that having DSA tag parsing split in two different files, under different folders (net/dsa/tag_ocelot.c vs drivers/net/dsa/ocelot/felix.c) made it quite non-obvious for patches to come that they might break this. Finally, the blamed commit does the following: at the end of ocelot_rcv(), it checks whether the skb payload contains a VLAN header. If it does, and this port is under a VLAN-aware bridge, that VLAN ID might not be correct in the sense that the packet might have suffered VLAN rewriting due to TCAM rules (VCAP IS1). So we consume the VLAN ID from the skb payload using __skb_vlan_pop(), and take the classified VLAN ID from the DSA tag, and construct a hwaccel VLAN tag with the classified VLAN, and the skb payload is VLAN-untagged. The big problem is that __skb_vlan_pop() does: memmove(skb->data + VLAN_HLEN, skb->data, 2 * ETH_ALEN); __skb_pull(skb, VLAN_HLEN); aka it moves the Ethernet header 4 bytes to the right, and pulls 4 bytes from the skb headroom (effectively also moving skb->data, by definition). So for felix_rxtstamp()'s fragile logic, all bets are off now. Instead of having the "extraction" pointer point to the DSA header, it actually points to 4 bytes _inside_ the extraction header. Corollary, the last 4 bytes of the "extraction" header are in fact 4 stale bytes of the destination MAC address from the Ethernet header, from prior to the __skb_vlan_pop() movement. So of course, RX timestamps are completely bogus when the system is configured in this way. The fix is actually very simple: just don't structure the code like that. For better or worse, the DSA PTP timestamping API does not offer a straightforward way for drivers to present their RX timestamps, but other drivers (sja1105) have established a simple mechanism to carry their RX timestamp from dsa_device_ops :: rcv() all the way to dsa_switch_ops :: port_rxtstamp() and even later. That mechanism is to simply save the partial timestamp to the skb->cb, and complete it later. Question: why don't we simply populate the skb's struct skb_shared_hwtstamps from ocelot_rcv(), and bother with this complication of propagating the timestamp to felix_rxtstamp()? Answer: dsa_switch_ops :: port_rxtstamp() answers the question whether PTP packets need sleepable context to retrieve the full RX timestamp. Currently felix_rxtstamp() answers "no, thanks" to that question, and calls ocelot_ptp_gettime64() from softirq atomic context. This is understandable, since Felix VSC9959 is a PCIe memory-mapped switch, so hardware access does not require sleeping. But the felix driver is preparing for the introduction of other switches where hardware access is over a slow bus like SPI or MDIO: https://lore.kernel.org/lkml/[email protected]/ So I would like to keep this code structure, so the rework needed when that driver will need PTP support will be minimal (answer "yes, I need deferred context for this skb's RX timestamp", then the partial timestamp will still be found in the skb->cb.

2021-11-03net: avoid double accounting for pure zerocopy skbsTalal Ahmad6-9/+53
Track skbs containing only zerocopy data and avoid charging them to kernel memory to correctly account the memory utilization for msg_zerocopy. All of the data in such skbs is held in user pages which are already accounted to user. Before this change, they are charged again in kernel in __zerocopy_sg_from_iter. The charging in kernel is excessive because data is not being copied into skb frags. This excessive charging can lead to kernel going into memory pressure state which impacts all sockets in the system adversely. Mark pure zerocopy skbs with a SKBFL_PURE_ZEROCOPY flag and remove charge/uncharge for data in such skbs. Initially, an skb is marked pure zerocopy when it is empty and in zerocopy path. skb can then change from a pure zerocopy skb to mixed data skb (zerocopy and copy data) if it is at tail of write queue and there is room available in it and non-zerocopy data is being sent in the next sendmsg call. At this time sk_mem_charge is done for the pure zerocopied data and the pure zerocopy flag is unmarked. We found that this happens very rarely on workloads that pass MSG_ZEROCOPY. A pure zerocopy skb can later be coalesced into normal skb if they are next to each other in queue but this patch prevents coalescing from happening. This avoids complexity of charging when skb downgrades from pure zerocopy to mixed. This is also rare. In sk_wmem_free_skb, if it is a pure zerocopy skb, an sk_mem_uncharge for SKB_TRUESIZE(skb_end_offset(skb)) is done for sk_mem_charge in tcp_skb_entail for an skb without data. Testing with the msg_zerocopy.c benchmark between two hosts(100G nics) with zerocopy showed that before this patch the 'sock' variable in memory.stat for cgroup2 that tracks sum of sk_forward_alloc, sk_rmem_alloc and sk_wmem_queued is around 1822720 and with this change it is 0. This is due to no charge to sk_forward_alloc for zerocopy data and shows memory utilization for kernel is lowered.

Xin Long says: ==================== security: fixups for the security hooks in sctp There are a couple of problems in the currect security hooks in sctp: 1. The hooks incorrectly treat sctp_endpoint in SCTP as request_sock in TCP, while it's in fact no more than an extension of the sock, and represents the local host. It is created when sock is created, not when a conn request comes. sctp_association is actually the correct one to represent the connection, and created when a conn request arrives. 2. security_sctp_assoc_request() hook should also be called in processing COOKIE ECHO, as that's the place where the real assoc is created and used in the future. The problems above may cause accept sk, peeloff sk or client sk having the incorrect security labels. So this patchset is to change some hooks and pass asoc into them and save these secids into asoc, as well as add the missing sctp_assoc_request hook into the COOKIE ECHO processing. v1->v2: - See each patch, and thanks the help from Ondrej, Paul and Richard. ==================== Signed-off-by: David S.

Different from selinux_inet_conn_established(), it also gives the secid to asoc->peer_secid in selinux_sctp_assoc_established(), as one UDP-type socket may have more than one asocs. Note that peer_secid in asoc will save the peer secid for this asoc connection, and peer_sid in sksec will just keep the peer secid for the latest connection. So the right use should be do peeloff for UDP-type socket if there will be multiple asocs in one socket, so that the peeloff socket has the right label for its asoc. v1->v2: - call selinux_inet_conn_established() to reduce some code duplication in selinux_sctp_assoc_established(), as Ondrej suggested. - when doing peeloff, it calls sock_create() where it actually gets secid for socket from socket_sockcreate_sid().
