register_sysctl_rotable never caught on as an interesting way to register sysctls. My take on the situation is that what we want are sysctls that we can only see in the initial network namespace. What we have implemented with register_sysctl_rotable are sysctls that we can see in all of the network namespaces and can only change in the initial network namespace. That is a very silly way to go. Just register the network sysctls in the initial network namespace and we don't have any weird special cases to deal with. The sysctls affected are: /proc/sys/net/ipv4/ipfrag_secret_interval /proc/sys/net/ipv4/ipfrag_max_dist /proc/sys/net/ipv6/ip6frag_secret_interval /proc/sys/net/ipv6/mld_max_msf I really don't expect anyone will miss them if they can't read them in a child user namespace.

Implementation limitations of the sysctl core won't let /proc/sys/net reside in a network namespace. /proc/sys/net at least must be registered as a normal sysctl. So register /proc/sys/net early as an empty directory to guarantee we don't violate this constraint and hit bugs in the sysctl implementation. Signed-off-by: NEric W.

Right now all of the networking sysctl registrations are running in a compatibiity mode. The natvie sysctl registration api takes a cstring for a path and a simple ctl_table. Implement register_net_sysctl so that we can register network sysctls without needing to use compatiblity code in the sysctl core. Switching from a ctl_path to a cstring results in less boiler plate and denser code that is a little easier to read. I would simply have changed the arguments to register_net_sysctl_table instead of keeping two functions in parallel but gcc will allow a ctl_path pointer to be passed to a char * pointer with only issuing a warning resulting in completely incorrect code can be built. Since I have to change the function name I am taking advantage of the situation to let both register_net_sysctl and register_net_sysctl_table live for a short time in parallel which makes clean conversion patches a bit easier to read and write.

On some platforms, for example where we are doing the bring-up, the csr clock is not passed from the framework and the Ethernet device driver is failing when it can work w/o any issues and using the default values.

Recently the dma parameters that can be passed from the platform have been moved from the plat_stmmacenet_data to the stmmac_dma_cfg. In case of this new structure is not well allocated the driver can fails. This is an example how this field is managed in ST platforms static struct stmmac_dma_cfg gmac_dma_setting = { .pbl = 32, }; static struct plat_stmmacenet_data stih415_ethernet_platform_data[] = { { .dma_cfg = &gmac_dma_setting, .has_gmac = 1, [snip] This patch so verifies that the dma_cfg passed from the platform. In case of it is NULL there is no reason that the driver has to fail and some default values can be passed. These are ok for all the Synopsys chips and could impact on performances, only.

Revises routines that deal with connections between two ports on the same node to ensure the connection is not impacted if the node's network address is changed in mid-operation. The routines now treat the default node address of <0.0.0> as an alias for "this node" in the following situations: 1) Incoming messages destined to a connected port now handle the alias properly when validating that the message was sent by the expected peer port, ensuring that the message will be accepted regardless of whether it specifies the node's old network address or it's current one. 2) The code which completes connection establishment now handles the alias properly when determining if the peer port is on the same node as the connected port. An added benefit of addressing issue 1) is that some peer port validation code has been relocated to TIPC's socket subsystem, which means that validation is no longer done twice when a message is sent to a non-socket port (such as TIPC's configuration service or network topology service).

Re-orders port creation logic so that the initialization of a new port's message header template occurs while the port list lock is held. This ensures that a change to the node's network address that occurs at the same time as the port is being created does not result in the template identifying the sender using the former network address. The new approach guarantees that the new port's template is using the current network address or that it will be updated when the address changes.

Introduces routines that test whether a given network address is equal to a node's own network address or if it lies within the node's own network cluster, and which work properly regardless of whether the node is using the default network address <0.0.0> or a non-zero network address that is assigned later on. In essence, these routines ensure that address <0.0.0> is treated as an alias for "this node", regardless of which network address the node is actually using. Old users of the pre-existing more strict match in_own_cluster() have been accordingly redirected to what is now called in_own_cluster_exact() --- which does not extend matching to <0,0,0>.

Ensures that node-scope name publications that exist prior to the configuration of a node's network address are properly re-initialized with that address when it is assigned. TIPC's node-scope publications are now tracked using a publications list like the lists used for cluster-scope and zone-scope publications so they can be easily updated when required. The inclusion of node scope name publications in a conventional publication list means that they must now also be withdrawn, just like cluster and zone scope publications are currently withdrawn. So some conditional tests on scope ==/!= TIPC_NODE_SCOPE are inserted/removed accordingly.

Utilizes distinct lists to track zone-scope and cluster-scope names published by a node. For now, TIPC continues to process the entries in both lists in the same way; however, an upcoming patch will utilize the existence of the lists to prevent the sending of cluster-scope names to nodes that are not part of the local cluster. To achieve this, an array of publication lists is introduced, so that they can be iterated over and accessed via publ->scope as an index where convenient.
