This is only an API consolidation and should make things more readable. Converting milliseconds to jiffies by "val * HZ / 1000" is technically OK but msecs_to_jiffies(val) is the cleaner solution and handles all corner cases correctly. This is a minor API cleanup only. Signed-off-by:

Tom Herbert says: ==================== net: Fixes to remote checksum offload and CHECKSUM_PARTIAL This patch set fixes a correctness problem with remote checksum offload, clarifies the meaning of CHECKSUM_PARTIAL, and allows remote checksum offload to set CHECKSUM_PARTIAL instead of calling csum_partial and modifying the checksum. Specifically: - In the GRO remote checksum path, restore the checksum after calling lower layer GRO functions. This is needed if the packet is forwarded off host with the Remote Checksum Offload option still present. - Clarify meaning of CHECKSUM PARTIAL in the receive path. Only the checksums referred to by checksum partial and any preceding checksums can be considered verified. - Fixes to UDP tunnel GRO complete. Need to set SKB_GSO_UDP_TUNNEL_*, SKB_GSO_TUNNEL_REMCSUM, and skb->encapsulation for forwarding case. - Infrastructure to allow setting of CHECKSUM_PARTIAL in remote checksum offload. This a potential performance benefit instead of calling csum_partial (potentially twice, once in GRO path and once in normal path). The downside of using CHECKSUM_PARTIAL and not actually writing the checksum is that we aren't verifying that the sender correctly wrote the pseudo checksum into the checksum field, or that the start/offset values actually point to a checksum. If the sender did not set up these fields correctly, a packet might be accepted locally, but not accepted by a peer when the packet is forwarded off host. Verifying these fields seems non-trivial, and because the fields can only be incorrect due to sender error and not corruption (outer checksum protects against that) we'll make use of CHECKSUM_PARTIAL the default. This behavior can be reverted as an netlink option on the encapsulation socket. - Change VXLAN and GUE to set CHECKSUM_PARTIAL in remote checksum offload by default, configuration hooks can revert to using csum_partial. Testing: I ran performance numbers using netperf TCP_STREAM and TCP_RR with 200 streams for GRE/GUE and for VXLAN. This compares before the fixes, the fixes with not setting checksum partial in remote checksum offload, and with the fixes setting checksum partial. The overall effect seems be that using checksum partial is a slight performance win, perf definitely shows a significant reduction of time in csum_partial on the receive CPUs.

This patch adds infrastructure so that remote checksum offload can set CHECKSUM_PARTIAL instead of calling csum_partial and writing the modfied checksum field. Add skb_remcsum_adjust_partial function to set an skb for using CHECKSUM_PARTIAL with remote checksum offload. Changed skb_remcsum_process and skb_gro_remcsum_process to take a boolean argument to indicate if checksum partial can be set or the checksum needs to be modified using the normal algorithm.

Properly set GSO types and skb->encapsulation in the UDP tunnel GRO complete so that packets are properly represented for GSO. This sets SKB_GSO_UDP_TUNNEL or SKB_GSO_UDP_TUNNEL_CSUM depending on whether non-zero checksums were received, and sets SKB_GSO_TUNNEL_REMCSUM if the remote checksum option was processed.

The current meaning of CHECKSUM_PARTIAL for validating checksums is that _all_ checksums in the packet are considered valid. However, in the manner that CHECKSUM_PARTIAL is set only the checksum at csum_start+csum_offset and any preceding checksums may be considered valid. If there are checksums in the packet after csum_offset it is possible they have not been verfied. This patch changes CHECKSUM_PARTIAL logic in skb_csum_unnecessary and __skb_gro_checksum_validate_needed to only considered checksums referring to csum_start and any preceding checksums (with starting offset before csum_start) to be verified.

Remote checksum offload processing is currently the same for both the GRO and non-GRO path. When the remote checksum offload option is encountered, the checksum field referred to is modified in the packet. So in the GRO case, the packet is modified in the GRO path and then the operation is skipped when the packet goes through the normal path based on skb->remcsum_offload. There is a problem in that the packet may be modified in the GRO path, but then forwarded off host still containing the remote checksum option. A remote host will again perform RCO but now the checksum verification will fail since GRO RCO already modified the checksum. To fix this, we ensure that GRO restores a packet to it's original state before returning. In this model, when GRO processes a remote checksum option it still changes the checksum per the algorithm but on return from lower layer processing the checksum is restored to its original value. In this patch we add define gro_remcsum structure which is passed to skb_gro_remcsum_process to save offset and delta for the checksum being changed. After lower layer processing, skb_gro_remcsum_cleanup is called to restore the checksum before returning from GRO. Signed-off-by:

When the RDS transport is TCP, we cannot inline the call to rds_send_xmit from rds_cong_queue_update because (a) we are already holding the sock_lock in the recv path, and will deadlock when tcp_setsockopt/tcp_sendmsg try to get the sock lock (b) cong_queue_update does an irqsave on the rds_cong_lock, and this will trigger warnings (for a good reason) from functions called out of sock_lock. This patch reverts the change introduced by 2fa57129 ("RDS: Bypass workqueue when queueing cong updates"). The patch has been verified for both RDS/TCP as well as RDS/RDMA to ensure that there are not regressions for either transport: - for verification of RDS/TCP a client-server unit-test was used, with the server blocked in gdb and thus unable to drain its rcvbuf, eventually triggering a RDS congestion update. - for RDS/RDMA, the standard IB regression tests were used Signed-off-by:

This one was driving me mad, with several lines of warnings during the allmodconfig build for a single bogus pointer cast. The warning was so verbose due to the indirect macro expansion explanation, and the whole thing was just for a debug printout. The bogus pointer-to-integer cast was pointless anyway, so just remove it, and use '%p' to show the pointer. Signed-off-by:

The firmware version is a single byte so have the variable type agree. Since the address to this member is passed to the read function, using an int is not even portable. Signed-off-by:

The device indicates the result of a read/write operation by making the status available on a subsequent request from the driver. This is not ready immediately, though, so the driver is currently slamming the device with hundreds of pointless requests before getting the expected response. Add a two millisecond delay before each attempt. This is approximately the behavior observed with version 4.2.7.1 of the Windows driver. Signed-off-by:

The BDW audio firmware DSP manages the DMA and the DMA cannot be stopped exactly at the end of the playback stream. This means stale samples may be played at PCM stop unless the driver copies silence to the subsequent periods. Signed-off-by:

Pull networking updates from David Miller: 1) More iov_iter conversion work from Al Viro. [ The "crypto: switch af_alg_make_sg() to iov_iter" commit was wrong, and this pull actually adds an extra commit on top of the branch I'm pulling to fix that up, so that the pre-merge state is ok. - Linus ] 2) Various optimizations to the ipv4 forwarding information base trie lookup implementation. From Alexander Duyck. 3) Remove sock_iocb altogether, from CHristoph Hellwig. 4) Allow congestion control algorithm selection via routing metrics. From Daniel Borkmann. 5) Make ipv4 uncached route list per-cpu, from Eric Dumazet. 6) Handle rfs hash collisions more gracefully, also from Eric Dumazet. 7) Add xmit_more support to r8169, e1000, and e1000e drivers. From Florian Westphal. 8) Transparent Ethernet Bridging support for GRO, from Jesse Gross. 9) Add BPF packet actions to packet scheduler, from Jiri Pirko. 10) Add support for uniqu flow IDs to openvswitch, from Joe Stringer. 11) New NetCP ethernet driver, from Muralidharan Karicheri and Wingman Kwok. 12) More sanely handle out-of-window dupacks, which can result in serious ACK storms. From Neal Cardwell. 13) Various rhashtable bug fixes and enhancements, from Herbert Xu, Patrick McHardy, and Thomas Graf. 14) Support xmit_more in be2net, from Sathya Perla. 15) Group Policy extensions for vxlan, from Thomas Graf. 16) Remove Checksum Offload support for vxlan, from Tom Herbert. 17) Like ipv4, support lockless transmit over ipv6 UDP sockets.

Commit 1d10eb2f ("crypto: switch af_alg_make_sg() to iov_iter") broke af_alg_make_sg() and skcipher_recvmsg() in the process of moving them to the iov_iter interfaces. The 'npages' calculation in the formar calculated the number of *bytes* in the pages, and in the latter case the conversion didn't re-read the value of 'ctx->used' after waiting for it to become non-zero. This reverts to the original code for both these cases. Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: David Miller <davem@davemloft.net> Signed-off-by:
