Transmission of an AP beacon does not call the TX interrupt service routine, which usually does the cleanup. Instead, cleanup is handled in a tasklet completion routine. Unfortunately, this routine has a serious bug in that it does not release the DMA mapping before it frees the skb, thus one IOMMU mapping is leaked for each beacon. The test system failed with no free IOMMU mapping slots approximately one hour after hostapd was used to start an AP. This issue was reported and tested at https://github.com/lwfinger/rtlwifi_new/issues/30. Reported-and-tested-by:

sc->nbcnvifs tracks assigned beacon slots, not enabled beacons. Therefore, it cannot be used to decide if cur_conf->enable_beacon (bool) should be updated, or if beacons have been enabled already. With the current code (depending on the order of calls), beacons often do not get enabled in an AP+STA setup. To fix tracking of enabled beacons, convert cur_conf->enable_beacon to a bitmask of enabled beacon slots. Cc: stable@vger.kernel.org Signed-off-by:

The commit below introduced an unsafe dereference of mvmvif->phy_ctxt. It can be NULL even if we hold the mutex. We can be handling a BT Coex notification while the vif has already been unassigned. This can happen since the BT Coex notification is hanled asynchronuously: we can have started to handle the BT Coex notification trying to acquire the mutex while the unassign flow already got it. The BT Coex notification handling will wait for the mutext. I'll get it later, but then mvmvif->phy_ctxt will be NULL.

Routine rtl_is_special_data() is supposed to identify packets that need to use a low bit rate so that the probability of successful transmission is high. The current version has a bug that causes all IPv6 packets to be labelled as special, with a corresponding low rate of transmission. A complete fix will be quite intrusive, but until that is available, all IPv6 packets are identified as regular. This patch also removes a magic number. Reported-and-tested-by:

If an over-MTU UDP datagram is sent through a SOCK_RAW socket to a UFO-capable device, ip_ufo_append_data() sets skb->ip_summed to CHECKSUM_PARTIAL unconditionally as all GSO code assumes transport layer checksum is to be computed on segmentation. However, in this case, skb->csum_start and skb->csum_offset are never set as raw socket transmit path bypasses udp_send_skb() where they are usually set. As a result, driver may access invalid memory when trying to calculate the checksum and store the result (as observed in virtio_net driver). Moreover, the very idea of modifying the userspace provided UDP header is IMHO against raw socket semantics (I wasn't able to find a document clearly stating this or the opposite, though). And while allowing CHECKSUM_NONE in the UFO case would be more efficient, it would be a bit too intrusive change just to handle a corner case like this. Therefore disallowing UFO for packets from SOCK_DGRAM seems to be the best option. Signed-off-by:

My previous fix to clear padding of short frames used skb->len as the DMA length, assuming that skb_padto() extended skb->len to include the padding. That isn't the case; we need to use skb_put_padto() instead. (This wasn't immediately obvious because software padding isn't actually needed on the R-Car H2. We could make it conditional on which chip is being driven, but it's probably not worth the effort.) Reported-by:

In case of RX ring underrun (RDE), we attempt to reset the software descriptor pointers (dirty_rx and cur_rx) to match where the hardware will read the next descriptor from, as that might not be the first dirty descriptor. This relies on reading RDFAR, but that register doesn't exist on all supported chips - specifically, not on the R-Car chips. This will result in unpredictable behaviour on those chips after an RDE. Make this pointer reset conditional and assume that it isn't needed on the R-Car chips. This fix also assumes that RDFAR is never exposed at offset 0 in the memory map - this is currently true, and a subsequent commit will fix the ambiguity between offset 0 and no-offset in the register offset maps.

To repeat: $ sudo ip link del hsr0 BUG: unable to handle kernel NULL pointer dereference at 0000000000000018 IP: [<ffffffff8187f495>] hsr_del_port+0x15/0xa0 etc... Bug description: As part of the hsr master device destruction, hsr_del_port() is called for each of the hsr ports. At each such call, the master device is updated regarding features and mtu. When the master device is freed before the slave interfaces, master will be NULL in hsr_del_port(), which led to a NULL pointer dereference. Additionally, dev_put() was called on the master device itself in hsr_del_port(), causing a refcnt error. A third bug in the same code path was that the rtnl lock was not taken before hsr_del_port() was called as part of hsr_dev_destroy(). The reporter (Nicolas Dichtel) also said: "hsr_netdev_notify() supposes that the port will always be available when the notification is for an hsr interface. It's wrong. For example, netdev_wait_allrefs() may resend NETDEV_UNREGISTER.". As a precaution against this, a check for port == NULL was added in hsr_dev_notify(). Reported-by:

Commit 740c7f31 ("sh_eth: Ensure DMA engines are stopped before freeing buffers") added a call to sh_eth_reset() to the sh_eth_set_ringparam() and sh_eth_close() paths. However, setting the software reset bit(s) in the EDMR register resets the MAC Address Registers to zero. Hence after kexec, the new kernel doesn't detect a valid MAC address and assigns a random MAC address, breaking DHCP. Set the MAC address again after the reset in sh_eth_dev_exit() to fix this.

The bcmgenet_tx_reclaim of tx_ring[{0,1,2,3}] operative by an interrupt is to be not more than a certain number TxBDs. It is caused by too slowly reclaiming the transmitted skb.

Brian reported crashes using IPv6 traffic with macvtap/veth combo. I tracked the crashes in neigh_hh_output() -> memcpy(skb->data - HH_DATA_MOD, hh->hh_data, HH_DATA_MOD); Neighbour code assumes headroom to push Ethernet header is at least 16 bytes. It appears macvtap has only 14 bytes available on arches where NET_IP_ALIGN is 0 (like x86) Effect is a corruption of 2 bytes right before skb->head, and possible crashes if accessing non existing memory. This fix should also increase IPv4 performance, as paranoid code in ip_finish_output2() wont have to call skb_realloc_headroom() Reported-by:
