One of the memset call is buggy: it does not erase full array, but only pointer size. Moreover, after a check, first step of nla_parse_nested/nla_parse is to erase tb array as well. We can remove both calls safely. Signed-off-by:

In the early days of phylib we had a functionality that changed to the next lower speed in fixed mode if no link was established after a certain period of time. This functionality has been removed years ago, and state PHY_FORCING isn't needed any longer. Instead we can go from UP to RUNNING or NOLINK directly (same as in autoneg mode). Signed-off-by:

The variable cache_allocs is to indicate how many frags (KiB) are in one rds connection frag cache. The command "rds-info -Iv" will output the rds connection cache statistics as below: " RDS IB Connections: LocalAddr RemoteAddr Tos SL LocalDev RemoteDev 1.1.1.14 1.1.1.14 58 255 fe80::2:c903:a:7a31 fe80::2:c903:a:7a31 send_wr=256, recv_wr=1024, send_sge=8, rdma_mr_max=4096, rdma_mr_size=257, cache_allocs=12 " This means that there are about 12KiB frag in this rds connection frag cache. Since rds.h in rds-tools is not related with the kernel rds.h, the change in kernel rds.h does not affect rds-tools. rds-info in rds-tools 2.0.5 and 2.0.6 is tested with this commit. It works well.

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct nfp_tun_active_tuns { ... struct route_ip_info { __be32 ipv4; __be32 egress_port; __be32 extra[2]; } tun_info[]; }; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(struct nfp_tun_active_tuns) + sizeof(struct route_ip_info) * count with: struct_size(payload, tun_info, count) This code was detected with the help of Coccinelle.

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2019-06-05 This series contains updates to mainly ixgbe, with a few updates to i40e, net, ice and hns2 driver. Jan adds support for tracking each queue pair for whether or not AF_XDP zero copy is enabled. Also updated the ixgbe driver to use the netdev-provided umems so that we do not need to contain these structures in our own adapter structure. William Tu provides two fixes for AF_XDP statistics which were causing incorrect counts. Jake reduces the PTP transmit timestamp timeout from 15 seconds to 1 second, which is still well after the maximum expected delay. Also fixes an issues with the PTP SDP pin setup which was not properly aligning on a full second, so updated the code to account for the cyclecounter multiplier and simplify the code to make the intent of the calculations more clear. Updated the function header comments to help with the code documentation. Added support for SDP/PPS output for x550 devices, which is slightly different than x540 devices that currently have this support. Anirudh adds a new define for Link Layer Discovery Protocol to the networking core, so that drivers do not have to create and use their own definitions. In addition, update all the drivers currently defining their own LLDP define to use the new networking core define. ==================== Signed-off-by: -

Similar to the X540 hardware, enable support for generating a 1pps output signal on SDP0. This support is slightly different to the X540 hardware, because of the register layout changes. First, the system time register is now represented in 'cycles' and 'billions of cycles'. Second, we need to also program the TSSDP register, as well as the ESDP register. Third, the clock output uses only FREQOUT, instead of a full 64bit value for the output clock period. Finally, we have to use the ST0 bit instead of the SYNCLK bit in the TSAUXC register. This support should work even for the hardware with a higher frequency clock, as it carefully takes into account the multiply and shift of the cycle counter used. We also set the pps configuration to 1, since we now support generating a pulse per second output. Signed-off-by:

The ixgbe_ptp.c file sometimes uses hw_cc as the local variable for the cycle counter in ixgbe_ptp_read_X550. However, we use just 'cc' as a local variable for this by convention else where in the file. Convert this lone usage of 'hw_cc' into just the shorter 'cc' name to match the other read functions in the file. Signed-off-by:

The function ixgbe_ptp_setup_sdp_X540 attempts to program a software defined pin, in order to generate a pulse-per-second output on SDP 0. It does work to generate the output, but does not align the output on the full second. Additionally, it does not take into account the cyclecounter multiplier. This leads to somewhat confusing code which is likely to be incorrect if blindly copied to another hardware type. Update this code to account for the cyclecounter multiplier, and to directly use timecounter_read. This change ensures that the SDP output will align properly on a full second, and makes the intent of the calculations a bit more clear. Signed-off-by:

Previously we waited for a whole 15 seconds before we cleared the Tx timestamp state. This is astronomically long compared to the worst case timings expected by our devices. In addition, this is longer than the wait in ptp4l when it detects a fault (caused by missing Tx timestamps). Thus, reduce the timer to only 1 second, which is well after the maximum expected delay. This should reduce user frustration when a timestamp does get dropped for some reason. Signed-off-by:
