Use tcp_jiffies32 instead of tcp_time_stamp to feed tp->snd_cwnd_stamp. tcp_time_stamp will soon be a litle bit more expensive than simply reading 'jiffies'. Signed-off-by:

We abuse tcp_time_stamp for two different cases : 1) base to generate TCP Timestamp options (RFC 7323) 2) A 32bit version of jiffies since some TCP fields are 32bit wide to save memory. Since we want in the future to have 1ms TCP TS clock, regardless of HZ value, we want to cleanup things. tcp_jiffies32 is the truncated jiffies value, which will be used only in places where we want a 'host' timestamp.

Idea is to later convert tp->tcp_mstamp to a full u64 counter using usec resolution, so that we can later have fine grained TCP TS clock (RFC 7323), regardless of HZ value. We try to refresh tp->tcp_mstamp only when necessary. Signed-off-by:

Jiri Pirko says: ==================== net: sched: introduce multichain support for filters Currently, each classful qdisc holds one chain of filters. This chain is traversed and each filter could be matched on, which may lead to execution of list of actions. One of such action could be "reclassify", which would "reset" the processing of the filter chain. So this filter chain could be looked at as a flat table. Sometimes it is convenient for user to configure a hierarchy of tables. Example usecase is encapsulation. Hierarchy of tables is a common way how it is done in HW pipelines. So it is much more convenient to offload this. This patchset contains two major patches: 8/10 - This patch introduces the support for having multiple chains of filters. 10/10 - This patch adds new control action to allow going to specified chain The rest of the patches are smaller or bigger depencies of those 2. Please see individual patch descriptions for details. Corresponding iproute2 patches are appended as a reply to this cover letter. Simple example: $ tc qdisc add dev eth0 ingress $ tc filter add dev eth0 parent ffff: protocol ip pref 33 flower dst_mac 52:54:00:3d:c7:6d action goto chain 11 $ tc filter add dev eth0 parent ffff: protocol ip pref 22 chain 11 flower dst_ip 192.168.40.1 action drop $ tc filter show dev eth0 root filter parent ffff: protocol ip pref 33 flower chain 0 filter parent ffff: protocol ip pref 33 flower chain 0 handle 0x1 dst_mac 52:54:00:3d:c7:6d eth_type ipv4 action order 1: gact action goto chain 11 random type none pass val 0 index 2 ref 1 bind 1 filter parent ffff: protocol ip pref 22 flower chain 11 filter parent ffff: protocol ip pref 22 flower chain 11 handle 0x1 eth_type ipv4 dst_ip 192.168.40.1 action order 1: gact action drop random type none pass val 0 index 3 ref 1 bind 1 ==================== Signed-off-by: -

Introduce new type of termination action called "goto_chain". This allows user to specify a chain to be processed. This action type is then processed as a return value in tcf_classify loop in similar way as "reclassify" is, only it does not reset to the first filter in chain but rather reset to the first filter of the desired chain.

Jiri Pirko authored
Instead of having only one filter per block, introduce a list of chains for every block. Create chain 0 by default. UAPI is extended so the user can specify which chain he wants to change. If the new attribute is not specified, chain 0 is used. That allows to maintain backward compatibility. If chain does not exist and user wants to manipulate with it, new chain is created with specified index. Also, when last filter is removed from the chain, the chain is destroyed. Signed-off-by:

Currently, the filter chains are direcly put into the private structures of qdiscs. In order to be able to have multiple chains per qdisc and to allow filter chains sharing among qdiscs, there is a need for common object that would hold the chains. This introduces such object and calls it "tcf_block". Helpers to get and put the blocks are provided to be called from individual qdisc code. Also, the original filter_list pointers are left in qdisc privs to allow the entry into tcf_block processing without any added overhead of possible multiple pointer dereference on fast path.

When multiple liquidio NICs are plugged in, the first insmod of the PF driver succeeds. But after an rmmod, a subsequent insmod fails. Reason is during rmmod, the PF driver resets the Octeon of only one of the NICs; it neglects to reset the Octeons of the other NICs. Fix the insmod failure by adding the missing Octeon resets at rmmod. Keep a per-NIC refcount that indicates the number of active PFs in a given NIC. When the refcount goes to zero, then reset the Octeon of that NIC. Signed-off-by:

A dsa_switch_tree instance holds a dsa_switch pointer and a port index to identify the switch port to which the CPU is attached. Now that the DSA layer has a dsa_port structure to hold this data, use it to point the switch CPU port. This patch simply substitutes s/dst->cpu_switch/dst->cpu_dp->ds/ and s/dst->cpu_port/dst->cpu_dp->index/. Signed-off-by:

Jiri Pirko says: ==================== mlxsw: Preparations for restructuring This patchset doesn't introduce any functional changes and merely meant to make the code base more receptive for upcoming restructuring. The first six patches mainly shuffle code in order to reduce the scope of structs that shouldn't be defined in the main driver header. Most of them will be later expanded, so it makes sense to correctly place them now. The last patches mostly simplify bridge-related functions, so that they could be more easily modified later on. ==================== Signed-off-by: -

In virtual mode, packets are classified to FIDs based on their ingress port and VLAN whereas in non-virtual mode only the VLAN is taken into account. Currently ports are initialized to use virtual mode due to the presence of the PVID vPort. However, we're going to transition ports between both modes based on the FIDs they use and not merely based on the presence on a VLAN upper. Therefore, during initialization, no mode will be explicitly set. Since the Programmer's Reference Manual (PRM) doesn't specify a default, explicitly set the port to non-virtual mode and later transition the port between both modes based on the FIDs it uses. In a follow-up patchset, this step will be moved to the common FID core where it logically belongs. Signed-off-by:

We no longer batch VLAN operations, so there's no need to set the learning state for a range of VLANs. Use a common function to set the learning state for a Port-VLAN, thereby making the code saner more receptive for upcoming changes. Signed-off-by:

Simplify the code by using the common function that sets an STP state for a Port-VLAN and remove the existing one that tries to batch it for several VLANs. This will help us in a follow-up patchset to introduce a unified infrastructure for bridge ports, regardless if the bridge is VLAN-aware or not. Signed-off-by:

switchdev's VLAN object has the ability to describe a range of VLAN IDs, but this is only used when VLAN operations are done using the SELF flag, which is something we would like to remove as it allows one to bypass the bridge driver. Do VLAN operations on a per-VLAN basis, thereby simplifying the code and preparing it for refactoring in a follow-up patchset. Signed-off-by:

Since commit 97c24290 ("switchdev: Execute bridge ndos only for bridge ports") switchdev code checks that port is bridged, so no need to perform the same check in the driver. Signed-off-by:

The router interfaces (RIFs) array is currently initialized together with the general router configuration. However, in a follow-up patchset we're going to introduce a common RIF core that will require us to initialize more RIF constructs, so move the RIF initialization to its own function. Signed-off-by:

Some attributes in the global chip struct are only relevant for bridge operation, so encapsulate them in their own struct that isn't exposed to non-bridge code. This will also help us later, when we add more bridge-specific attributes. Signed-off-by:
