On RTL8411b the RX unit gets confused if the PHY is powered-down. This was reported in [0] and confirmed by Realtek. Realtek provided a sequence to fix the RX unit after PHY wakeup.

2019-07-12ppp: mppe: Revert "ppp: mppe: Add softdep to arc4"Eric Biggers1-1/+0
Commit 0e5a610b5ca5 ("ppp: mppe: switch to RC4 library interface"), which was merged through the crypto tree for v5.3, changed ppp_mppe.c to use the new arc4_crypt() library function rather than access RC4 through the dynamic crypto_skcipher API. Meanwhile commit aad1dcc4f011 ("ppp: mppe: Add softdep to arc4") was merged through the net tree and added a module soft-dependency on "arc4". The latter commit no longer makes sense because the code now uses the "libarc4" module rather than "arc4", and also due to the direct use of arc4_crypt(), no module soft-dependency is required.

The cudbg_collect_mem_region() and cudbg_read_fw_mem() both use several hundred kilobytes of kernel stack space. One gets inlined into the other, which causes the stack usage to be combined beyond the warning limit when building with clang: drivers/net/ethernet/chelsio/cxgb4/cudbg_lib.c:1057:12: error: stack frame size of 1244 bytes in function 'cudbg_collect_mem_region' [-Werror,-Wframe-larger-than=] Restructuring cudbg_collect_mem_region() lets clang do the same optimization that gcc does and reuse the stack slots as it can see that the large variables are never used together. A better fix might be to avoid using cudbg_meminfo on the stack altogether, but that requires a larger rewrite.

2019-07-12nfp: flower: ensure ip protocol is specified for L4 matchesJohn Hurley1-9/+6
Flower rules on the NFP firmware are able to match on an IP protocol field. When parsing rules in the driver, unknown IP protocols are only rejected when further matches are to be carried out on layer 4 fields, as the firmware will not be able to extract such fields from packets. L4 protocol dissectors such as FLOW_DISSECTOR_KEY_PORTS are only parsed if an IP protocol is specified. This leaves a loophole whereby a rule that attempts to match on transport layer information such as port numbers but does not explicitly give an IP protocol type can be incorrectly offloaded (in this case with wildcard port numbers matches). Fix this by rejecting the offload of flows that attempt to match on L4 information, not only when matching on an unknown IP protocol type, but also when the protocol is wildcarded.

2019-07-12nfp: flower: fix ethernet check on match fieldsJohn Hurley1-8/+5
NFP firmware does not explicitly match on an ethernet type field. Rather, each rule has a bitmask of match fields that can be used to infer the ethernet type. Currently, if a flower rule contains an unknown ethernet type, a check is carried out for matches on other fields of the packet. If matches on layer 3 or 4 are found, then the offload is rejected as firmware will not be able to extract these fields from a packet with an ethernet type it does not currently understand. However, if a rule contains an unknown ethernet type without any L3 (or above) matches then this will effectively be offloaded as a rule with a wildcarded ethertype. This can lead to misclassifications on the firmware. Fix this issue by rejecting all flower rules that specify a match on an unknown ethernet type. Further ensure correct offloads by moving the 'L3 and above' check to any rule that does not specify an ethernet type and rejecting rules with further matches. This means that we can still offload rules with a wildcarded ethertype if they only match on L2 fields but will prevent rules which match on further fields that we cannot be sure if the firmware will be able to extract.

2019-07-12net/mlx5e: Provide cb_list pointer when setting up tc block on repVlad Buslov1-1/+4
Recent refactoring of tc block offloads infrastructure introduced new flow_block_cb_setup_simple() method intended to be used as unified way for all drivers to register offload callbacks.

In mlx5e_setup_tc "priv" variable is not being used if CONFIG_MLX5_ESWITCH is off, one way to fix this is to actually use it. mlx5e_setup_tc_mqprio also needs the "priv" variable and it extracts it on its own. We can simply pass priv to mlx5e_setup_tc_mqprio instead of netdev and avoid extracting the priv var, which will also resolve the compiler warning.

Most drivers do the same thing to set up the flow block callbacks, this patch adds a helper function to do this. This preparation patch reduces the number of changes to adapt the existing drivers to use the flow block callback API. This new helper function takes a flow block list per-driver, which is set to NULL until this driver list is used. This patch also introduces the flow_block_command and flow_block_binder_type enumerations, which are renamed to use FLOW_BLOCK_* in follow up patches. There are three definitions (aliases) in order to reduce the number of updates in this patch, which go away once drivers are fully adapted to use this flow block API.
