So, do this once and use it instead. Thus, we can remove some duplicate code and make it more readable. Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: David S.

This was diagnosed from sk_wmem_alloc value reaching maximum value of sk_sndbuf. TX_QUEUE (assoc->sndbuf_used), sk_wmem_alloc and sk_wmem_queued values are incremented in sctp_set_owner_w() for outgoing data chunks. Having access to the above values in /proc/net/sctp/assocs will provide a better understanding of SCTP buffer management. With patch applied, example output when peer.rwnd = 0 where: ASSOC ffff880132298000 is sender ffff880125343000 is receiver ASSOC SOCK STY SST ST HBKT ASSOC-ID TX_QUEUE RX_QUEUE \ ffff880132298000 ffff880124a0a0c0 2 1 3 29325 1 214656 0 \ ffff880125343000 ffff8801237d7700 2 1 3 36210 2 0 524520 \ UID INODE LPORT RPORT LADDRS <-> RADDRS HBINT INS OUTS \ 0 25108 3455 3456 *10.4.8.3 <-> *10.5.8.3 7500 2 2 \ 0 27819 3456 3455 *10.5.8.3 <-> *10.4.8.3 7500 2 2 \ MAXRT T1X T2X RTXC wmema wmemq sndbuf rcvbuf 4 0 0 72 525633 440320 524288 524288 4 0 0 0 1 0 524288 524288 Signed-off-by: Dilip Daya <dilip.daya@hp.com> Acked-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S.

In other words, once an address has been synced to a destination device, it will not be synced to any other device through the sync API. However, there are some virtual devices that aggreate a number of lower devices and need to sync addresses to all of them. The current API falls short there. This patch introduces a new dev_uc_sync_multiple() api that can be called in the above circumstances and allows sync to work for every invocation.

If BQL is not enabled, TSQ has then no effect. It turns out the GSO engine frees the original gso_skb at the time the fragments are generated and queued to the NIC. We should instead call the tcp_wfree() destructor for the last fragment, to keep the flow control as intended in TSQ. This effectively limits the number of queued packets on qdisc + NIC layers.

Copying the DSCP in IPsec tunneling may be a bit dangerous because packets with different DSCP may get reordered relative to each other in the network and then dropped by the remote IPsec GW if the reordering becomes too big compared to the replay window. It is possible to avoid this copy with netfilter rules, but it's very convenient to be able to configure it for each SA directly. This patch adds a toogle for this purpose. By default, it's not set to maintain backward compatibility. Field flags in struct xfrm_usersa_info is full, hence I add a new attribute.

This patch changes the hci_update_ad() function to take a request pointer and updates its users appropriately. E.g. the function is no longer called after the init sequence but during stage 3 of the init sequence. The TX power is read during the init sequence, so we don't need an explicit update whenever it is read and the AD update based on the local name should be done through the local name mgmt handler. The only other user is the update based on enabling advertising. This part is still kept as there is no mgmt API to enable it.

This patch fixes the issue by running the local name HCI command and the EIR update in the same asynchronous request, and returning the mgmt command complete through the complete callback of the request. The downside of this is that we must set hdev->dev_name before the local name HCI command has completed since otherwise the generated EIR command doesn't contain the new name. This means that we can no-longer reliably detect when the name has really changed and when not. Luckily this only affects scenarios where the mgmt interface is *not* used (e.g. hciconfig) so redundant mgmt_ev_local_name_changed events in these cases are an acceptable drawback.

The simplest way to monitor conflicts that should trigger "busy" error returns is to check for any pending mgmt command that can trigger these HCI commands. This patch adds a helper function for this (pending_eir_or_class) and uses it instead of the old HCI_PENDING_CLASS flag to test for busy conditions.
