In user-space there's no way to distinguish why an mdb entry was deleted and that is a problem for daemons which would like to keep the mdb in sync with remote ends (e.g. mlag) but would also like to converge faster. In almost all cases we'd like to age-out the remote entry for performance and convergence reasons except when fast-leave is enabled. In that case we want explicit immediate remote delete, thus add mdb flag which is set only when the entry is being deleted due to fast-leave. Signed-off-by:

The -d command line argument to tdc requires the name of a physical device on the system where the tests will be run. If -d has not been used, tdc will skip tests that require a physical device. This patch is intended to better document what the -d option does and how it is used. Signed-off-by:

Saeed Mahameed says: ==================== mlx5-updates-2019-07-29 This series includes updates to mlx5 driver, 1) Simplifications, cleanup and warning prints improvements 2) From Vlad Buslov: Refactor mlx5 tc flow handling for unlocked execution (Part 1) Currently, all cls API hardware offloads driver callbacks require caller to hold rtnl lock when calling them. Cls API has already been updated to update software filters in parallel (on classifiers that support unlocked execution), however hardware offloads code still obtains rtnl lock before calling driver tc callbacks. This set implements partial support for unlocked execution that is leveraged by follow up refactorings in specific mlx5 tc subsystems and patch to cls API that implements API that allows drivers to register their callbacks as rtnl-unlocked. In mlx5 tc code mlx5e_tc_flow is the main structure that is used to represent tc filter. Currently, code the structure itself and its handlers in both tc and eswitch layers do not implement any kind of synchronizations and assume external global synchronization provided by rtnl lock instead. Implement following changes to remove dependency on rtnl lock in flow handling code that are intended to be used a groundwork for following changes to provide fully rtnl-independent mlx5 tc: - Extend struct mlx5e_tc_flow with atomic reference counter and rcu to allow concurrent access from multiple tc and neigh update workqueue instances without introducing any additional locks specific to the structure. Its 'flags' field type is changed to atomic bitmask ops which is necessary for tc to interact with other concurrent tc instances or concurrent neigh update that need to skip flows that are not fully initialized (new INIT_DONE flow flag) and can change the flags according to neighbor state (flipping OFFLOADED flag). - Protect unready flows list by new uplink_priv->unready_flows_lock mutex. - Convert calls to netdev APIs that require rtnl lock in flow handling code to their rcu counterparts. - Modify eswitch code that is called from tc layer and assume implicit external synchronization to be concurrency safe: change esw->offloads.num_flows type to atomic integer and re-arrange esw->state_lock usage to protect additional data. Some of approaches to synchronizations presented in this patch set are quite complicated (lockless concurrent usage of data structures with rcu and reference counting, using fine-grained locking when necessary, retry mechanisms to handle concurrent insertion of another instance of data structure with same key, etc.). This is necessary to allow calling the firmware in parallel in most cases, which is the main motivation of this change since firmware calls are mach heavier operation than atomic operations, multitude of locks and potential multiple retries during concurrent accesses to same elements. ==================== Signed-off-by:

In case of HE AP-STA link, ieee80211_send_nullfunc() will not send the QOS NULL packet to check if AP is still associated. In this case, probe_send_count will be non-zero and ieee80211_sta_work() will later disassociate the AP, even though no packet was ever sent. Fix this by decrementing probe_send_count and not calling ieee80211_send_nullfunc() in case of HE link, so that we still wait for some time for the AP beacon to reappear and don't disconnect right away.

Over time, we really need to get rid of all of our global locking. One of the things needed is to use parallel_ops. This isn't really the most important (RTNL is much more important) but OTOH we just keep adding uses of genl_family_attrbuf() now. Use .parallel_ops to disallow this. Reviewed-By:

While I was testing the v2 of this series I discovered an huge use of memory, so I added patch 1 to mitigate this issue. I put it in this series in order to better track the performance trends. v5: - rebased all patches on net-next - added Stefan's R-b and Michael's A-b v4: https://patchwork.kernel.org/cover/11047717 v3: https://patchwork.kernel.org/cover/10970145 v2: https://patchwork.kernel.org/cover/10938743 v1: https://patchwork.kernel.org/cover/10885431 Below are the benchmarks step by step.

Since virtio-vsock was introduced, the buffers filled by the host and pushed to the guest using the vring, are directly queued in a per-socket list. These buffers are preallocated by the guest with a fixed size (4 KB). The maximum amount of memory used by each socket should be controlled by the credit mechanism. The default credit available per-socket is 256 KB, but if we use only 1 byte per packet, the guest can queue up to 262144 of 4 KB buffers, using up to 1 GB of memory per-socket. In addition, the guest will continue to fill the vring with new 4 KB free buffers to avoid starvation of other sockets. This patch mitigates this issue copying the payload of small packets (< 128 bytes) into the buffer of last packet queued, in order to avoid wasting memory. Signed-off-by:

__sctp_connect is doing quit similar things as sctp_sendmsg_new_asoc. To factor out common functions, this patch is to clean up their code to make them look more similar: 1. create the asoc and add a peer with the 1st addr. 2. add peers with the other addrs into this asoc one by one. while at it, also remove the unused 'addrcnt'.

Now __sctp_connect() is called by __sctp_setsockopt_connectx() and sctp_inet_connect(), the latter has done addr_size check with size of sa_family_t. In the next patch to clean up __sctp_connect(), we will remove addr_size check with size of sa_family_t from __sctp_connect() for the 1st address. So before doing that, __sctp_setsockopt_connectx() should do this check first, as sctp_inet_connect() does. Signed-off-by:
