2022-03-05bnxt_en: Eliminate unintended link toggle during FW resetMichael Chan1-3/+1
If the flow control settings have been changed, a subsequent FW reset may cause the ethernet link to toggle unnecessarily. This link toggle will increase the down time by a few seconds. The problem is caused by bnxt_update_phy_setting() detecting a false mismatch in the flow control settings between the stored software settings and the current FW settings after the FW reset. This mismatch is caused by the AUTONEG bit added to link_info->req_flow_ctrl in an inconsistent way in bnxt_set_pauseparam() in autoneg mode. The AUTONEG bit should not be added to link_info->req_flow_ctrl.

If a memory allocation error occurred during an attempt to refill a slot in the RX ring after the packet was received, the hardware tail pointer would still have been updated to point to or past the slot which remained marked as previously completed. This would likely result in the DMA engine raising an error when it eventually tried to use that slot again. If a slot cannot be refilled, then just stop processing and do not move the tail pointer past it. On the next attempt, we should skip receiving the packet from the empty slot and just try to refill it again. This failure mode has not actually been observed, but was found as part of other driver updates.

Luiz Angelo Daros de Luca says: ==================== net: dsa: realtek: add rtl8_4t tag This patch series adds support for rtl8_4t tag. It is a variant of rtl8_4 tag, with identical values but placed at the end of the packet (before CRC). It forces checksum in software before adding the tag as those extra bytes at the end of the packet would be summed together with the rest of the payload. When the switch removes the tag before sending the packet to the network, that checksum will not match. It might be useful to diagnose or avoid checksum offload issues. With an ethertype tag like rtl8_4, the cpu port ethernet driver must work with cksum_start and chksum_offset to correctly calculate checksums. If not, the checksum field will be broken (it will contain the fake ip header sum). In those cases, using 'rtl8_4t' might be an alternative way to avoid checksum offload, either using runtime or device-tree property. Regards, Luiz v4-v5) - tags in alphabetical order in dsa_port.yaml - remove ret var from rtl8365mb_change_tag_protocol - Comment typos fixes v3-v4) - added rtl8_4 and rtl8_4t to dsa_port.yaml - removed generic considerations about checksum problems with DSA tags.

2022-03-04selftests: mptcp: update output info of chk_rm_nrGeliang Tang1-8/+9
This patch updated the output info of chk_rm_nr. Renamed 'sf' to 'rmsf', which means 'remove subflow'. Added the display of whether the inverted namespaces has been used to check the mib counters. The new output looks like this: 002 remove multiple subflows syn[ ok ] - synack[ ok ] - ack[ ok ] rm [ ok ] - rmsf [ ok ] 003 remove single address syn[ ok ] - synack[ ok ] - ack[ ok ] add[ ok ] - echo [ ok ] rm [ ok ] - rmsf [ ok ] invert Signed-off-by: Geliang Tang <[email protected]> Signed-off-by: Mat Martineau <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>
2022-03-04selftests: mptcp: add more arguments for chk_join_nrGeliang Tang1-14/+33
This patch added five more arguments for chk_join_nr(). The default values of them are all zero. The first two, csum_ns1 and csum_ns1, are passed to chk_csum_nr(), to check the mib counters of the checksum errors in ns1 and ns2. A '+' can be added into this two arguments to represent that multiple checksum errors are allowed when doing this check. For example, chk_csum_nr "" +2 +2 indicates that two or more checksum errors are allowed in both ns1 and ns2. The remaining two, fail_nr and rst_nr, are passed to chk_fail_nr() and chk_rst_nr() respectively, to check the sending and receiving mib counters of MP_FAIL and MP_RST. Also did some cleanups in chk_fail_nr(), renamed two local variables and updated the output message.

2022-03-04selftests: mptcp: add invert check in check_transferGeliang Tang1-8/+17
This patch added the invert bytes check for the output data in check_transfer(). Instead of the file mismatch error: [ FAIL ] file received by server does not match (in, out): -rw------- 1 root root 45643832 Jan 16 15:04 /tmp/tmp.9xpM6Paivv Trailing bytes are: MPTCP_TEST_FILE_END_MARKER -rw------- 1 root root 45643832 Jan 16 15:04 /tmp/tmp.wnz1Yp4u7Z Trailing bytes are: MPTCP_TEST_FILE_END_MARKER Print out the inverted bytes like this: file received by server has inverted byte at 7454789 file received by server has inverted byte at 7454790 file received by server has inverted byte at 7454791 file received by server has inverted byte at 7454792 Signed-off-by: Geliang Tang <[email protected]> Signed-off-by: Mat Martineau <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>
2022-03-04selftests: mptcp: add fastclose testcaseGeliang Tang1-1/+21
This patch added the self test for MP_FASTCLOSE. Reused the argument addr_nr_ns2 of do_transfer() to pass the extra arguments '-I 2' to mptcp_connect commands. Then mptcp_connect disconnected the connections to trigger the MP_FASTCLOSE sending and receiving. Used chk_fclose_nr to check the MP_FASTCLOSE mibs and used chk_rst_nr to check the MP_RST mibs. This test used the test_linkfail value to make 1024KB test files. The output looks like this: Created /tmp/tmp.XB8sfv1hJ0 (size 1024 KB) containing data sent by client Created /tmp/tmp.RtTDbzqrXI (size 1024 KB) containing data sent by server 001 fastclose test syn[ ok ] - synack[ ok ] - ack[ ok ] ctx[ ok ] - fclzrx[ ok ] rtx[ ok ] - rstrx [ ok ] invert Signed-off-by: Geliang Tang <[email protected]> Signed-off-by: Mat Martineau <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>
2022-03-04selftests: mptcp: reuse linkfail to make given size filesGeliang Tang1-5/+27
This patch reused the test_linkfail values above 2 to make test files with the given sizes (KB) for both the client side and the server side. It's useful for the test cases using different file sizes.

2022-03-04selftests: mptcp: add extra_args in do_transferGeliang Tang1-15/+15
Instead of using a global variable mptcp_connect, this patch added a new local variable extra_args in do_transfer() to store the extra arguments passing to the mptcp_connect commands. This patch also renamed the speed level 'least' to 'speed_*'. This more flexible way can avoid the need to add new speed levels in the future.

2022-03-04selftests: mptcp: add the MP_RST mibs checkGeliang Tang1-0/+45
This patch added a new function chk_rst_nr() to check the numbers of the MP_RST sending and receiving mibs. Showed in the output whether the inverted namespaces check order is used. Since if we pass -Cz to mptcp_join.sh, the MP_RST information is showed twice.

2022-03-04mptcp: add the mibs for MP_RSTGeliang Tang3-0/+6
This patch added two more mibs for MP_RST, MPTCP_MIB_MPRSTTX for the MP_RST sending and MPTCP_MIB_MPRSTRX for the MP_RST receiving. Signed-off-by: Geliang Tang <[email protected]> Signed-off-by: Mat Martineau <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>
