Change overload control to be purely byte-based, using sk->sk_rmem_alloc as byte counter, and compare it to a calculated upper limit for the socket receive queue. For all connection messages, irrespective of message importance, the overload limit is set to a constant value (i.e, 67MB). This limit should normally never be reached because of the lower limit used by the flow control algorithm, and is there only as a last resort in case a faulty peer doesn't respect the send window limit. For datagram messages, message importance is taken into account when calculating the overload limit. The calculation is based on sk->sk_rcvbuf, and is hence configurable via the socket option SO_RCVBUF.

Jeff Kirsher says: ==================== This series contains updates to igb and ixgbe. Most of the changes are against igb, except for one patch against ixgbe. There are 3 igb fixes from Carolyn which were reported by Dan Carpenter which resolve issues found in the get_i2c_client(). Alex does some cleanup of the igb driver to match similar functionality in ixgbe on transmit. Alex also makes it so that we can enable the use of build_skb for cases where jumbo frames are disabled. The advantage to this is that we do not have to perform a memcpy to populate the header and as a result we see a significant performance improvement. Akeem provides 4 patches to initialize function pointers and do a re-factoring of the function pointers in igb_get_variants() to assist with driver debugging. The ixgbe patch comes from Emil to reshuffle the switch/case structure of the flag assignment to allow for the flags to be set for each MAC type separately. This is needed for new hardware that does not have feature parity with older hardware. v2: updated patches 4 & 5 based on feedback from Ben Hutchings and Eric Dumazet ==================== Signed-off-by: NDavid S.

Following patch adds GRE protocol offload handler so that skb_gso_segment() can segment GRE packets. SKB GSO CB is added to keep track of total header length so that skb_segment can push entire header. e.g. in case of GRE, skb_segment need to push inner and outer headers to every segment. New NETIF_F_GRE_GSO feature is added for devices which support HW GRE TSO offload. Currently none of devices support it therefore GRE GSO always fall backs to software GSO.

After reviewing the igb and ixgbe code I realized there are a few issues in how the code is structured. Specifically we are not checking the size of the buffers being used in transmits and we are not using the same value to determine when to stop or start a Tx queue. As such the code is prone to be buggy. This patch makes it so that we have one value DESC_NEEDED that we will use for starting and stopping the queue. In addition we will check the size of buffers being used when setting up a transmit so as to avoid a possible buffer overrun if we were to receive a frame with a block of data larger than 32K in skb->data.

由 Claudiu Manoil 提交于
This fixes a less obvious error on one hand, and prevents futher similar errors by disambiguating and optimizing RxFCB indication, on the other hand. The error consists in NETIF_F_HW_VLAN_TX flag being used as an indication of Rx FCB insertion. This happened as soon gfar_uses_fcb(), which despite its name indicates Rx FCB insertion, started incorporating is_vlan_on(). is_vlan_on(), on the other hand, is also a misleading construct because we need to differentiate b/w hw VLAN extraction/VLEX (marked by VLAN_RX flag) and hw VLAN insertion/VLINS (VLAN_TX flag), which are different mechanisms using different types of FCBs. The hw spec for the RxFCB feature is as follows: In the case of RxBD rings, FCBs (Frame Control Block) are inserted by the eTSEC whenever RCTRL[PRSDEP] is set to a non-zero value. Only one FCB is inserted per frame (in the buffer pointed to by the RxBD with bit F set). TOE acceleration for receive is enabled for all rx frames in this case. This patch introduces priv->uses_rxfcb field to quickly signal RxFCB insertion in accordance with the specification above. The dependency on FSL_GIANFAR_DEV_HAS_TIMER was also eliminated as another source of confusion. The actual dependency is to priv->hwts_rx_en. Upon changing priv->hwts_rx_en via IOCTL, the gfar device is being restarted and on init_mac() the priv->hwts_rx_en flag determines RxFCB insertion, and rctrl is programmed accordingly. The patch takes care of this case too. Though maybe not as self documenting as the inlining version uses_fcb(), priv->uses_rxfcb has the main purpose to quickly signal, on the hot path, that the incoming frame has a *Rx* FCB block inserted which needs to be pulled out before passing the skb to the stack. This is a performance critical operation, it needs to happen fast, that's why uses_rxfcb is placed in the first cacheline of gfar_private. This is also why a cached rctrl cannot be used instead: 1) because we don't have 32 bits available in the first cacheline of gfar_priv (but only 16); 2) bit operations are expensive on the hot path.

The controller's ref manual states clearly that when the hw Rx vlan offload feature is enabled, meaning that the VLEX bit from RCTRL is correctly enabled, then the hw performs automatic VLAN tag extraction and deletion from the ethernet frames. So there's no point in trying to increase the rx buff size when rxvlan is on, as the frame is actually smaller. And the Tx vlan hw accel feature (VLINS) has nothing to do with rx buff size computation. Signed-off-by: NClaudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: NDavid S.

Group run-time critical fields within the 1st cacheline (32B) followed by the tx|rx_queue reference arrays and the interrupt group instances (gfargrp), all cacheline aligned. This has several benefits. Firstly comes the performance benefit by having the members required by the driver's hot path re-grouped in the structure's first cache lines, whereas the unimportant members were pushed towards the end of the struct. Another benefit comes from eliminating a 24 byte memory hole that was rendering gfar_priv's 2nd cacheline useless. The default gcc layout of gfar_private leaves an implicit 24 byte hole after the errata (enum) member. This patch fixes it. The uchar bitfields were pushed towards the end of the struct as these are not run-time performance critical (used for init time operations). Because there is no other 2 byte member around to couple the uchar bitfields memeber with, we will have an addititnal 2 byte hole after the bitfields. This is unsignificant however, and it doesn't influence gfar_priv's size, because the whole structure is padded to be a 32B multiple.

Use device pointer (dev) to simplify the code and to avoid double indirections, especially on the hot path. Basically, instead of accessing priv to get the ofdev reference and then accessing the ofdev structure to dereference the needed dev pointer, we will get the dev pointer directly from priv. The dev pointer is required on the hot path, see gfar_new_rxbdp or gfar_clean_rx_ring (or xmit), and this patch makes it available directly from priv's 1st cacheline. This change is reflected at asm level too, taking (the hot) gfar_new_rxbdp(): initial version - 18c0: 7c 7e 1b 78 mr r30,r3 18d0: 81 69 04 3c lwz r11,1084(r9) 18d8: 34 6b 00 10 addic. r3,r11,16 18dc: 41 82 00 08 beq- 18e4 patched version - 18d0: 80 69 04 38 lwz r3,1080(r9) 18d8: 2f 83 00 00 cmpwi cr7,r3,0 18dc: 41 9e 00 08 beq- cr7,18e4 Signed-off-by: NClaudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: NDavid S.

Vlad Yasevich says: ==================== VLAN filtering/VLAN aware bridge Changes since v10 * Updated implemenation of ndo_fdb_del in emulex and qlogic drivers. Changes since v9: * series re-ordering so make functionality more distinct. Basic vlan filtering is patches 1-4. Support for PVID/untagged vlans is patches 5 and 6. VLAN support for FDB/MDB is patches 7-11. Patch 12 is still additional egress policy. * Slight simplification to code that extracts the VID from skb. Since we now depend on the vlan module, at the time of input skb_tci is guaranteed to be set if the packet had 8021q header. We can simply refere to it. * Changed the opaque 'parent' pointer from prior patches to a union so we can be much more explicit in our assignments. * Lots of additional testing with STP turned on. No issues were observed. Changes since v8: * Unified vlans_to_* calls into a single interface * Fixed the rest of the issues report by Michal Miroslaw * Fixed a bug where fdb entries were not created for all added vlans. Changes since v7: * Rebases on the latest net-next and removed the vlan wrapper patch from the series. * Fixed a crash in br_fdb_add/br_fdb_delete. Changes since v6: * VLANs are now stored in a VLAN bitmap per port. This allows for O(1) lookup at ingress and egress. We simply check to see if the bit associated with the vlan id is set in the map. The drawback to this approach is that it wastes some space when there is only a small number of VLANs. * In addition to the build time configuration option, VLAN filtering also has a configuration paramter in sysfs. By default the filtering is turned off and all traffic is permitted. When the filtring is turned on, we do strict matching to the filter configured. Thus, if there is no configuration, all packets are rejected. This was done to make the behavior more streight forward. Without this (and if egress policy patch is rejected), the decision for how to forward untagged traffic that was not filtered at ingress is almost impossible to make. It would not be right to deliver to every port that has PVID set as, each port may have a different PVID. * Separate egress policy bitmap patch has been isolated and is provided last in the series. This has been a more contentious piece of functionality and I wanted to isolate it so that it could easily be dropped and not block the whole series. Changes since v5: - Pulled VLAN filtering into its own file and made it a configuration options. - Made new vlan filtering option dependent on VLAN_8021Q. - Got rid of HW filter inlines and moved then vlan_core.c. (All of the above suggested by Stephen Hemminger) Changes since v4: - Pull per-port vlan data into its own structures and give it to the bridge device thus making bridge device behave like a regular port for vlan configuration. - Add a per-vlan 'untagged' bitmap that determins egress policy. If a port is part of this bitmap, traffic egresses untagged. - PVID is now used for ingress policy only. Incomming frames without VLAN tag are assigned to the PVID vlan. Egress is determined via bitmap memberships. - Allow for incremental config of a vlan. Now, PVID and untagged memberships may be set on existing vlans. They however can NOT be cleared separately. - VLAN deletion is now done via RTM_DELLINK command for PF_BRIDGE family. This cleans up the netlink interface. Changes since v3: - Re-integrated compiler problems that got left out last time. Appologies. - checkpatches.pl errors fixed Changes since v2: - Added inline functiosn to manimulate vlan hw filters and re-use in 8021q and bridge code. - Use rtnl_dereference (Michael Tsirkin) - Remove synchronize_net() call (Eric Dumazet) - Fix NULL ptr deref bug I introduced in br_ifinfo_notify. Changes since v1: - Fixed some forwarding bugs. - Add vlan to local fdb entries. New local entries are created per vlan to facilite correct forwarding to bridge interface. - Allow configuration of vlans directly on the bridge master device in addition to ports. Changes since rfc v2: - Per-port vlan bitmap is gone and is replaced with a vlan list. - Added bridge vlan list, which is referenced by each port. Entries in the birdge vlan list have port bitmap that shows which port are parts of which vlan. - Netlink API changes. - Dropped sysfs support for now. If people think this is really usefull, can add it back. - Support for native/untagged vlans. Changes since rfc v1: - Comments addressed regarding formatting and RCU usage - iocts have been removed and changed over the netlink interface. - Added support of user added ndb entries. - changed sysfs interface to export a bitmap. Also added a write interface. I am not sure how much I like it, but it made my testing easier/faster. I might change the write interface to take text instead of binary. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Add an ability to configure a separate "untagged" egress policy to the VLAN information of the bridge. This superseeds PVID policy and makes PVID ingress-only. The policy is configured with a new flag and is represented as a port bitmap per vlan. Egress frames with a VLAN id in "untagged" policy bitmap would egress the port without VLAN header.

When VLAN is added to the port, a local fdb entry for that port (the entry with the mac address of the port) is added for that VLAN. This way we can correctly determine if the traffic is for the bridge itself. If the address of the port changes, we try to change all the local fdb entries we have for that port.
