2021-07-01s390: iucv: Avoid field over-reading memcpy()Kees Cook
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally reading across neighboring array fields. Add a wrapping struct to serve as the memcpy() source so the compiler can perform appropriate bounds checking, avoiding this future warning: In function '__fortify_memcpy', inlined from 'iucv_message_pending' at net/iucv/iucv.c:1663:4: ./include/linux/fortify-string.h:246:4: error: call to '__read_overflow2_field' declared with attribute error: detected read beyond size of field (2nd parameter) Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Karsten Graul <kgraul@linux.ibm.com> Signed-off-by: David S.

2021-07-01tcp: consistently disable header prediction for mptcpPaolo Abeni
The MPTCP receive path is hooked only into the TCP slow-path. The DSS presence allows plain MPTCP traffic to hit that consistently. Since commit e1ff9e82e2ea ("net: mptcp: improve fallback to TCP"), when an MPTCP socket falls back to TCP, it can hit the TCP receive fast-path, and delay or stop triggering the event notification. Address the issue explicitly disabling the header prediction for MPTCP sockets.

2021-07-01ibmvnic: retry reset if there are no other resetsSukadev Bhattiprolu
Normally, if a reset fails due to failover or other communication error there is another reset (eg: FAILOVER) in the queue and we would process that reset. But if we are unable to communicate with PHYP or VIOS after H_FREE_CRQ, there would be no other resets in the queue and the adapter would be in an undefined state even though it was in the OPEN state earlier. While starting the reset we set the carrier to off state so we won't even get the timeout resets. If the last queued reset fails, retry it as a hard reset (after the usual 60 second settling time).

2021-07-01Merge branch 'ptp-virtual-clocks-and-timestamping'David S. Miller
Yangbo Lu says: ==================== ptp: support virtual clocks and timestamping Current PTP driver exposes one PTP device to user which binds network interface/interfaces to provide timestamping. Actually we have a way utilizing timecounter/cyclecounter to virtualize any number of PTP clocks based on a same free running physical clock for using. The purpose of having multiple PTP virtual clocks is for user space to directly/easily use them for multiple domains synchronization. user space: ^ ^ | SO_TIMESTAMPING new flag: | Packets with | SOF_TIMESTAMPING_BIND_PHC | TX/RX HW timestamps v v +--------------------------------------------+ sock: | sock (new member sk_bind_phc) | +--------------------------------------------+ ^ ^ | ethtool_get_phc_vclocks | Convert HW timestamps | | to sk_bind_phc v v +--------------+--------------+--------------+ vclock: | ptp1 | ptp2 | ptpN | +--------------+--------------+--------------+ pclock: | ptp0 free running | +--------------------------------------------+ The block diagram may explain how it works. Besides the PTP virtual clocks, the packet HW timestamp converting to the bound PHC is also done in sock driver. For user space, PTP virtual clocks can be created via sysfs, and extended SO_TIMESTAMPING API (new flag SOF_TIMESTAMPING_BIND_PHC) can be used to bind one PTP virtual clock for timestamping. The test tool timestamping.c (together with linuxptp phc_ctl tool) can be used to verify: # echo 4 > /sys/class/ptp/ptp0/n_vclocks [ 129.399472] ptp ptp0: new virtual clock ptp2 [ 129.404234] ptp ptp0: new virtual clock ptp3 [ 129.409532] ptp ptp0: new virtual clock ptp4 [ 129.413942] ptp ptp0: new virtual clock ptp5 [ 129.418257] ptp ptp0: guarantee physical clock free running # # phc_ctl /dev/ptp2 set 10000 # phc_ctl /dev/ptp3 set 20000 # # timestamping eno0 2 SOF_TIMESTAMPING_TX_HARDWARE SOF_TIMESTAMPING_RAW_HARDWARE SOF_TIMESTAMPING_BIND_PHC # timestamping eno0 2 SOF_TIMESTAMPING_RX_HARDWARE SOF_TIMESTAMPING_RAW_HARDWARE SOF_TIMESTAMPING_BIND_PHC # timestamping eno0 3 SOF_TIMESTAMPING_TX_HARDWARE SOF_TIMESTAMPING_RAW_HARDWARE SOF_TIMESTAMPING_BIND_PHC # timestamping eno0 3 SOF_TIMESTAMPING_RX_HARDWARE SOF_TIMESTAMPING_RAW_HARDWARE SOF_TIMESTAMPING_BIND_PHC Changes for v2: - Converted to num_vclocks for creating virtual clocks. - Guranteed physical clock free running when using virtual clocks. - Fixed build warning. - Updated copyright.

2021-07-01sctp: move 198 addresses from unusable to private scopeXin Long
The doc draft-stewart-tsvwg-sctp-ipv4-00 that restricts 198 addresses was never published. These addresses as private addresses should be allowed to use in SCTP. As Michael Tuexen suggested, this patch is to move 198 addresses from unusable to private scope.

2021-07-01net: bcmgenet: ensure EXT_ENERGY_DET_MASK is clearDoug Berger
Setting the EXT_ENERGY_DET_MASK bit allows the port energy detection logic of the internal PHY to prevent the system from sleeping. Some internal PHYs will report that energy is detected when the network interface is closed which can prevent the system from going to sleep if WoL is enabled when the interface is brought down. Since the driver does not support waking the system on this logic, this commit clears the bit whenever the internal PHY is powered up and the other logic for manipulating the bit is removed since it serves no useful function.

2021-07-01net: dsa: return -EOPNOTSUPP when driver does not implement .port_lag_joinVladimir Oltean
The DSA core has a layered structure, and even though we end up returning 0 (success) to user space when setting a bonding/team upper that can't be offloaded, some parts of the framework actually need to know that we couldn't offload that. For example, if dsa_switch_lag_join returns 0 as it currently does, dsa_port_lag_join has no way to tell a successful offload from a software fallback, and it will call dsa_port_bridge_join afterwards. Then we'll think we're offloading the bridge master of the LAG, when in fact we're not even offloading the LAG. In turn, this will make us set skb->offload_fwd_mark = true, which is incorrect and the bridge doesn't like it.

2021-07-01Merge branch 'octeopntx2-LMTST-regions'David S. Miller
Geetha sowjanya says: ==================== Dynamic LMTST region setup This patch series allows RVU PF/VF to allocate memory for LMTST operations instead of using memory reserved by firmware which is mapped as device memory. The LMTST mapping table contains the RVU PF/VF LMTST memory base address entries. This table is used by hardware for LMTST operations. Patch1 introduces new mailbox message to update the LMTST table with the new allocated memory address. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2021-07-01octeontx2-pf: cn10k: Use runtime allocated LMTLINE regionGeetha sowjanya
The current driver uses static LMTST region allocated by firmware. This memory gets populated as PF/VF BAR2. RVU PF/VF driver ioremap the memory as device memory for NIX/NPA operation. Since the memory is mapped as device memory we see performance degration. To address this issue this patch implements runtime memory allocation. RVU PF/VF allocates memory during device probe and share the base address with RVU AF. RVU AF then configure the LMT MAP table accordingly.

2021-07-01octeontx2-af: cn10k: Support configurable LMTST regionsGeetha sowjanya
This patch extends the lmtst_tbl_setup_req mbox to support run time LMTST configuration. RVU PF/VF and DPDK/ODP allocates a LMT region, creates a translation entry for a device via VFIO IOCTLs. This IOVA is shared with AF through above mbox. AF then uses RVU_SMMU transulation Widget and gets PA for the IOVA and updates the LMTtable entry for that device.
