The SO_TXTIME API enables packet tranmission with delayed delivery. This is currently supported by the ETF and FQ packet schedulers. Evaluate the interface with both schedulers. Install the scheduler and send a variety of packets streams: without delay, with one delayed packet, with multiple ordered delays and with reordering. Verify that packets are released by the scheduler in expected order. The ETF qdisc requires a timestamp in the future on every packet. It needs a delay on the qdisc else the packet is dropped on dequeue for having a delivery time in the past. The test value is experimentally derived. ETF requires clock_id CLOCK_TAI. It checks this base and drops for non-conformance. The FQ qdisc expects clock_id CLOCK_MONOTONIC, the base used by TCP as of commit fb420d5d ("tcp/fq: move back to CLOCK_MONOTONIC"). Within a flow there is an expecation of ordered delivery, as shown by delivery times of test 4. The FQ qdisc does not require all packets to have timestamps and does not drop for non-conformance. The large (msec) delays are chosen to avoid flakiness. Output: SO_TXTIME ipv6 clock monotonic payload:a delay:28 expected:0 (us) SO_TXTIME ipv4 clock monotonic payload:a delay:38 expected:0 (us) SO_TXTIME ipv6 clock monotonic payload:a delay:40 expected:0 (us) SO_TXTIME ipv4 clock monotonic payload:a delay:33 expected:0 (us) SO_TXTIME ipv6 clock monotonic payload:a delay:10120 expected:10000 (us) SO_TXTIME ipv4 clock monotonic payload:a delay:10102 expected:10000 (us) [.. etc ..] OK.

David Ahern says: ==================== ipv6: Move exceptions to fib6_nh and make it optional in a fib6_info Patches 1 and 4 move pcpu and exception caches from fib6_info to fib6_nh. With respect to the current FIB entries this is only a movement from one struct to another contained within the first. Patch 2 refactors the core logic of fib6_drop_pcpu_from into a helper that is invoked per fib6_nh. Patch 3 refactors exception handling in a similar way - creating a bunch of helpers that can be invoked per fib6_nh with the goal of making patch 4 easier to review as well as creating the code needed for nexthop objects. Patch 5 makes a fib6_nh at the end of a fib6_info an array similar to IPv4 and its fib_info. For the current fib entry model, all fib6_info will have a fib6_nh allocated for it. Patch 6 refactors ip6_route_del moving the code for deleting an exception entry into a new function. Patch 7 adds tests for redirect route exceptions. The new test was written against 5.1 (before any of the nexthop refactoring). It and the pmtu.sh selftest exercise the exception code paths - from creating exceptions to cleaning them up on device delete. All tests pass without any rcu locking or memleak warnings. ==================== Signed-off-by: -

Move the removal of cached routes to a helper, ip6_del_cached_rt, that can be invoked per nexthop. Rename the existig ip6_del_cached_rt to __ip6_del_cached_rt since it is called by ip6_del_cached_rt. Signed-off-by:

Move fib6_nh to the end of fib6_info and make it an array of size 0. Pass a flag to fib6_info_alloc indicating if the allocation needs to add space for a fib6_nh. The current code path always has a fib6_nh allocated with a fib6_info; with nexthop objects they will be separate. Signed-off-by:

David Ahern authored
Similar to the pcpu routes exceptions are really per nexthop, so move rt6i_exception_bucket from fib6_info to fib6_nh. To avoid additional increases to the size of fib6_nh for a 1-bit flag, use the lowest bit in the allocated memory pointer for the flushed flag. Add helpers for retrieving the bucket pointer to mask off the flag. The cleanup of the exception bucket is moved to fib6_nh_release. fib6_nh_flush_exceptions can now be called from 2 contexts: 1. deleting a fib entry 2. deleting a fib6_nh For 1., fib6_nh_flush_exceptions is called for a specific fib6_info that is getting deleted. All exceptions in the cache using the entry are deleted. For 2, the fib6_nh itself is getting destroyed so fib6_nh_flush_exceptions is called for a NULL fib6_info which means flush all entries. The pmtu.sh selftest exercises the affected code paths - from creating exceptions to cleaning them up on device delete. All tests pass without any rcu locking or memleak warnings. Signed-off-by:

Before moving exception bucket from fib6_info to fib6_nh, refactor rt6_flush_exceptions, rt6_remove_exception_rt, rt6_mtu_change_route, and rt6_update_exception_stamp_rt. In all 3 cases, move the primary logic into a new helper that starts with fib6_nh_. The latter 3 functions still take a fib6_info; this will be changed to fib6_nh in the next patch. In the case of rt6_mtu_change_route, move the fib6_metric_locked out as a standalone check - no need to call the new function if the fib entry has the mtu locked. Also, add fib6_info to rt6_mtu_change_arg as a way of passing the fib entry to the new helper. No functional change intended. The goal here is to make the next patch easier to review by moving existing lookup logic for each to new helpers. Signed-off-by:

Move the existing pcpu walk in fib6_drop_pcpu_from to a new helper, __fib6_drop_pcpu_from, that can be invoked per fib6_nh with a reference to the from entries that need to be evicted. If the passed in 'from' is non-NULL then only entries associated with that fib6_info are removed (e.g., case where fib entry is deleted); if the 'from' is NULL are entries are flushed (e.g., fib6_nh is deleted). For fib6_info entries with builtin fib6_nh (ie., current code) there is no change in behavior. Signed-off-by:

rt6_info are specific instances of a fib entry and are tied to a device and gateway - ie., a nexthop. Before nexthop objects, IPv6 fib entries have separate fib6_info for each nexthop in a multipath route, so the location of the pcpu cache in the fib6_info struct worked. However, with nexthop objects a fib6_info can point to a set of nexthops (yet another alignment of ipv6 with ipv4). Accordingly, the pcpu cache needs to be moved to the fib6_nh struct so the cached entries are local to the nexthop specification used to create the rt6_info. Initialization and free of the pcpu entries moved to fib6_nh_init and fib6_nh_release. Change in location only, from fib6_info down to fib6_nh; no other functional change intended. Signed-off-by:

Because the ENETC RX BD ring dynamic allocation has not been supported and it is too expensive to use extended RX BDs if timestamping is not used, a Kconfig option is used to enable extended RX BDs in order to support hardware timestamping. This option will be removed once RX BD ring dynamic allocation is implemented. ==================== Signed-off-by: -

This patch is to add hardware timestamping support for ENETC. On Rx, timestamping is enabled for all frames. On Tx, we only instruct the hardware to timestamp the frames marked accordingly by the stack. Because the RX BD ring dynamic allocation has not been supported and it is too expensive to use extended RX BDs if timestamping is not used, a Kconfig option is used to enable extended RX BDs in order to support hardware timestamping. This option will be removed once RX BD ring dynamic allocation is implemented. Signed-off-by:

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2019-05-23 This series contains updates to ice driver only. Anirudh cleans up white space issues and other code formatting issues in the driver. Also implemented LLDP persistence across reboots and start/stop of the LLDP agent. Updated print statements for driver capabilities to include if it is a device or function capability. Bruce cleaned up variable declarations by removing unneeded assignment. Dave fixes a potential hang due to a couple of flows that recursively acquire the RTNL lock which results in a deadlock. Tony updates the driver to advertise what link modes we are capable of when the user does not request a specific link mode. Usha fixes up the LLDP MIB change event handling by cleaning up workarounds and print the DCB configuration changes detected. Brett fixes the driver to handle failures in the VF reset path, which was failing to free resources upon an error. Richard fixed the reported of stats via ethtool to align with our other Intel drivers. Jesse optimizes the transmit buffer and ring structures to have more efficient ordering to get hot cache lines to have packed data. Also optimized the VF structure to use less memory, since it is used hundreds of times throughout the driver. ==================== Signed-off-by:

Currently the driver is calling ice_napi_del() and then unregister_netdev(). The call to unregister_netdev() will result in a call to ice_stop() and then ice_vsi_close(). This is where we call napi_disable() for all the MSI-X vectors. This flow is reversed so make the changes to ensure napi_disable() happens prior to napi_del(). Before calling napi_del() and free_netdev() make sure unregister_netdev() was called. This is done by making sure the __ICE_DOWN bit is set in the vsi->state for the interested VSI. Signed-off-by:

Currently if ice_reset_all_vfs() fails in ice_alloc_vfs() we fail to free some resources, reset variables, and return an error value. Fix this by adding another unroll case to free the pf->vf array, set the pf->num_alloc_vfs to 0, and return an error code. Without this, if ice_reset_all_vfs() fails in ice_alloc_vfs() we will not be able to do SRIOV without hard rebooting the system because rmmod'ing the driver does not work. Signed-off-by:

ice_parse_caps is used to parse both device and function capabilities. Currently, capabilities are printed with a cryptic "HW caps" prefix, which makes it difficult to distinguish whether the capabilities being printed are device or function capabilities. This patch makes a change to add a "func cap" prefix when printing function capabilities, and a "dev cap" prefix when printing device capabilities. This patch also changes some of the capability print strings for consistency. Signed-off-by:
