2017-02-19sctp: sctp_transport_dst_check should check if transport pmtu is dst mtuXin Long
Now when sending a packet, sctp_transport_dst_check will check if dst is obsolete by calling ipv4/ip6_dst_check. But they return obsolete only when adding a new cache, after that when the cache's pmtu is updated again, it will not trigger transport->dst/pmtu's update. It can be reproduced by reducing route's pmtu twice. At the 1st time client will add a new cache, and transport->pathmtu gets updated as sctp_transport_dst_check finds it's obsolete. But at the 2nd time, cache's mtu is updated, sctp client will never send out any packet, because transport->pmtu has no chance to update. This patch is to fix this by also checking if transport pmtu is dst mtu in sctp_transport_dst_check, so that transport->pmtu can be updated on time.

Consistently use types from linux/types.h to fix the following linux/target_core_user.h userspace compilation errors: /usr/include/linux/target_core_user.h:108:4: error: unknown type name 'uint32_t' uint32_t iov_cnt; /usr/include/linux/target_core_user.h:109:4: error: unknown type name 'uint32_t' uint32_t iov_bidi_cnt; /usr/include/linux/target_core_user.h:110:4: error: unknown type name 'uint32_t' uint32_t iov_dif_cnt; /usr/include/linux/target_core_user.h:111:4: error: unknown type name 'uint64_t' uint64_t cdb_off; /usr/include/linux/target_core_user.h:112:4: error: unknown type name 'uint64_t' uint64_t __pad1; /usr/include/linux/target_core_user.h:113:4: error: unknown type name 'uint64_t' uint64_t __pad2; /usr/include/linux/target_core_user.h:117:4: error: unknown type name 'uint8_t' uint8_t scsi_status; /usr/include/linux/target_core_user.h:118:4: error: unknown type name 'uint8_t' uint8_t __pad1; /usr/include/linux/target_core_user.h:119:4: error: unknown type name 'uint16_t' uint16_t __pad2; /usr/include/linux/target_core_user.h:120:4: error: unknown type name 'uint32_t' uint32_t __pad3; Signed-off-by: Dmitry V.

2017-02-18target/iscsi: split iscsit_check_dataout_hdr()Varun Prakash
Split iscsit_check_dataout_hdr() into two functions 1. __iscsit_check_dataout_hdr() - This function validates data out hdr. 2. iscsit_check_dataout_hdr() - This function finds iSCSI cmd using iscsit_find_cmd_from_itt_or_dump(), then it calls __iscsit_check_dataout_hdr() to validate iSCSI hdr. This split is required to support Chelsio T6 iSCSI DDP completion feature. T6 adapters reduce number of completions to host by generating single completion for all directly placed(DDP) iSCSI pdus in a sequence, DDP completion contains iSCSI hdr of the last pdu in a sequence. On receiving DDP completion cxgbit driver will first find iSCSI cmd using iscsit_find_cmd_from_itt_or_dump() then updates cmd->write_data_done, cmd->next_burst_len, cmd->data_sn and calls __iscsit_check_dataout_hdr() to validate iSCSI hdr.
