net: qed: fix left elements count calculation

2020-07-01T03:17:12Z

[ Upstream commit 97dd1abd026ae4e6a82fa68645928404ad483409 ] qed_chain_get_element_left{,_u32} returned 0 when the difference between producer and consumer page count was equal to the total page count. Fix this by conditional expanding of producer value (vs unconditional). This allowed to eliminate normalizaton against total page count, which was the cause of this bug. Misc: replace open-coded constants with common defines.

qed: Fix use after free in qed_chain_free

2020-05-02T15:26:00Z

commit 8063f761cd7c17fc1d0018728936e0c33a25388a upstream. The qed_chain data structure was modified in commit 1a4a69751f4d ("qed: Chain support for external PBL") to support receiving an external pbl (due to iWARP FW requirements). The pages pointed to by the pbl are allocated in qed_chain_alloc and their virtual address are stored in an virtual addresses array to enable accessing and freeing the data. The physical addresses however weren't stored and were accessed directly from the external-pbl during free. Destroy-qp flow, leads to freeing the external pbl before the chain is freed, when the chain is freed it tries accessing the already freed external pbl, leading to a use-after-free. Therefore we need to store the physical addresses in additional to the virtual addresses in a new data structure.

qed: Fix qed_chain_set_prod() for PBL chains with non power of 2 page count

2019-02-27T09:08:52Z

[ Upstream commit 2d533a9287f2011632977e87ce2783f4c689c984 ] In PBL chains with non power of 2 page count, the producer is not at the beginning of the chain when index is 0 after a wrap. Therefore, after the producer index wrap around, page index should be calculated more carefully. Signed-off-by: Denis Bolotin Signed-off-by: Ariel Elior Signed-off-by: David S.

qed/qede: Multi CoS support.

2018-08-09T21:05:30Z

This patch adds support for tc mqprio offload, using this different traffic classes on the adapter can be utilized based on configured priority to tc map. For example - tc qdisc add dev eth0 root mqprio num_tc 4 map 0 1 2 3 This will cause SKBs with priority 0,1,2,3 to transmit over tc 0,1,2,3 hardware queues respectively.

qed*: Utilize FW 8.37.2.0

2018-06-05T14:48:09Z

This FW contains several fixes and features. RDMA - Several modifications and fixes for Memory Windows - drop vlan and tcp timestamp from mss calculation in driver for this FW - Fix SQ completion flow when local ack timeout is infinite - Modifications in t10dif support ETH - Fix aRFS for tunneled traffic without inner IP. - Fix chip configuration which may fail under heavy traffic conditions. - Support receiving any-VNI in VXLAN and GENEVE RX classification. iSCSI / FcoE - Fix iSCSI recovery flow - Drop vlan and tcp timestamp from mss calc for fw 8.37.2.0 Misc - Several registers (split registers) won't read correctly with ethtool -d Signed-off-by: Ariel Elior Signed-off-by: Manish Rangankar Signed-off-by: Michal Kalderon Signed-off-by: David S.

qed: Add srq core support for RoCE and iWARP

qed*: Add link change count value to ethtool statistics display.

This patch adds driver changes for capturing the link change count in ethtool statistics display. Please consider applying this to "net-next". Signed-off-by: Sudarsana Reddy Kalluru Signed-off-by: Ariel Elior Signed-off-by: David S. Miller

qed*: Support drop action classification

2018-05-25T20:10:42Z

With this patch, User can configure for the supported flows to be dropped. Added a stat "gft_filter_drop" as well to be populated in ethtool for the dropped flows. For example - ethtool -N p5p1 flow-type udp4 dst-port 8000 action -1 ethtool -N p5p1 flow-type tcp4 scr-ip 192.168.8.1 action -1 Signed-off-by: Manish Chopra Signed-off-by: Shahed Shaikh Signed-off-by: Ariel Elior Signed-off-by: David S.

qed*: Support other classification modes.

2018-05-25T20:10:42Z

Currently, driver supports flow classification to PF receive queues based on TCP/UDP 4 tuples [src_ip, dst_ip, src_port, dst_port] only. This patch enables to configure different flow profiles [For example - only UDP dest port or src_ip based] on the adapter so that classification can be done according to just those fields as well. Although, at a time just one type of flow configuration is supported due to limited number of flow profiles available on the device. For example - ethtool -N enp7s0f0 flow-type udp4 dst-port 45762 action 2 ethtool -N enp7s0f0 flow-type tcp4 src-ip 192.16.4.10 action 1 ethtool -N enp7s0f0 flow-type udp6 dst-port 45762 action 3 Signed-off-by: Manish Chopra Signed-off-by: Shahed Shaikh Signed-off-by: Ariel Elior Signed-off-by: David S.
