The RTL8153-AD supports a persistent system specific MAC address. This means a device plugged into two different systems with host side support will show different (but persistent) MAC addresses. This information for the system's persistent MAC address is burned in when the system HW is built and available under \_SB.AMAC in the DSDT at runtime. This technology is currently implemented in the Dell TB15 and WD15 Type-C docks.

Sergei Trofimovich reported that pulse audio sends SCM_CREDENTIALS as a control message to TCP. Since __sock_cmsg_send does not support SCM_RIGHTS and SCM_CREDENTIALS, it returns an error and hence breaks pulse audio over TCP. SCM_RIGHTS and SCM_CREDENTIALS are sent on the SOL_SOCKET layer but they semantically belong to SOL_UNIX. Since all cmsg-processing functions including sock_cmsg_send ignore control messages of other layers, it is best to ignore SCM_RIGHTS and SCM_CREDENTIALS for consistency (and also for fixing pulse audio over TCP).

Yue Cao claims that current host rate limiting of challenge ACKS (RFC 5961) could leak enough information to allow a patient attacker to hijack TCP sessions. He will soon provide details in an academic paper. This patch increases the default limit from 100 to 1000, and adds some randomization so that the attacker can no longer hijack sessions without spending a considerable amount of probes. Based on initial analysis and patch from Linus. Note that we also have per socket rate limiting, so it is tempting to remove the host limit in the future. v2: randomize the count of challenge acks per second, not the period.

In some cases, if there is no VNIC server available during the driver probe, the driver should wait until it receives an initialization request from the VNIC Server to start the login process.

This patch creates a function that handles sub-CRQ IRQ creation separately from sub-CRQ initialization. Another function is then needed to release sub-CRQ resources prior to sub-CRQ IRQ creation. These additions allow the driver probe function to be simplified, specifically during the VNIC Server login process. A timeout is also included while waiting for completion of the login process in case the VNIC Server is not available or some other error occurs.

This is due to that a parallel ppp_unregister_channel() could happen while we are in ppp_connect_channel(), during which pch->chan_net set to NULL. Since we need a reference to net per channel, it makes sense to sync the refcnt with the life time of the channel, therefore we should release this reference when we destroy it.

由 Dmitri Epshtein 提交于
Commit aebea2ba ("net: mvneta: fix Tx interrupt delay") intended to set coalescing threshold to a value guaranteeing interrupt generation per each sent packet, so that buffers can be released with no delay. In fact setting threshold to '1' was wrong, because it causes interrupt every two packets. According to the documentation a reason behind it is following - interrupt occurs once sent buffers counter reaches a value, which is higher than one specified in MVNETA_TXQ_SIZE_REG(q). This behavior was confirmed during tests. Also when testing the SoC working as a NAS device, better performance was observed with int-per-packet, as it strongly depends on the fact that all transmitted packets are released immediately. This commit enables NETA controller work in interrupt per sent packet mode by setting coalescing threshold to 0.

Speedy join only works when the received packet is either broadcast or an 4addr unicast packet. Thus packets converted from broadcast to unicast via the gateway handling code have to be converted to 4addr packets to allow the receiving gateway server to add the sender address as temporary entry to the translation table. Not doing it will make the batman-adv gateway server drop the DHCP response in many situations because it doesn't yet have the TT entry for the destination of the DHCP response.

vlan_insert_tag can return NULL on errors. The bridge loop avoidance code therefore has to check the return value of vlan_insert_tag for NULL before it can safely operate on this pointer.

A qeth_card contains a napi_struct linked to the net_device during device probing. This struct must be deleted when removing the qeth device, otherwise Panic on oops can occur when qeth devices are repeatedly removed and added.
