* rds: rdma: update rdma transport for tosSantosh Shilimkar2019-02-046-22/+29
| | | | | | | | | | | | | | | | | | | | | | For RDMA transports, RDS TOS is an extension of IB QoS(Annex A13) to provide clients the ability to segregate traffic flows for different type of data. RDMA CM abstract it for ULPs using rdma_set_service_type(). Internally, each traffic flow is represented by a connection with all of its independent resources like that of a normal connection, and is differentiated by service type. In other words, there can be multiple qp connections between an IP pair and each supports a unique service type. The feature has been added from RDSv4.1 onwards and supports rolling upgrades. RDMA connection metadata also carries the tos information to set up SL on end to end context. The original code was developed by Bang Nguyen in downstream kernel back in 2.6.32 kernel days and it has evolved over period of time.

| | | | | | | | | | | | RDMA transport maps user tos to underline virtual lanes(VL) for IB or DSCP values. RDMA CM transport abstract thats for RDS. TCP transport makes use of default priority 0 and maps all user tos values to it.

* rds: add type of service(tos) infrastructureSantosh Shilimkar2019-02-0411-17/+72
| | | | | | | | | | | | RDS Service type (TOS) is user-defined and needs to be configured via RDS IOCTL interface. It must be set before initiating any traffic and once set the TOS can not be changed. All out-going traffic from the socket will be associated with its TOS.

* rds: rdma: add consumer rejectSantosh Shilimkar2019-02-043-2/+22
| | | | | | | | | | | | | | | For legacy protocol version incompatibility with non linux RDS, consumer reject reason being used to convey it to peer. But the choice of reject reason value as '1' was really poor. Anyway for interoperability reasons with shipping products, it needs to be supported. For any future versions, properly encoded reject reason should to be used.

The time data types used for the existing socket timestamp options: SO_TIMESTAMP, SO_TIMESTAMPNS and SO_TIMESTAMPING are not y2038 safe. The series introduces SO_TIMESTAMP_NEW, SO_TIMESTAMPNS_NEW and SO_TIMESTAMPING_NEW to replace these. These new timestamps can be used on all architectures. The alternative considered was to extend the sys_setsockopt() by using the flags. We did not receive any strong opinions about either of the approaches. Hence, this was chosen, as glibc folks preferred this. The series does not deal with updating the internal kernel socket calls like rxrpc to make them y2038 safe. This will be dealt with separately. Note that the timestamps behavior already does not match the man page specific behavior: SIOCGSTAMP This ioctl should only be used if the socket option SO_TIMESTAMP is not set on the socket. Otherwise, it returns the timestamp of the last packet that was received while SO_TIMESTAMP was not set, or it fails if no such packet has been received, (i.e., ioctl(2) returns -1 with errno set to ENOENT). The recommendation is to update the man page to remove the above statement. The overview of the socket timestamp series is as below: 1. Delete asm specific socket.h when possible. 2. Support SO/SCM_TIMESTAMP* options only in userspace. 3. Rename current SO/SCM_TIMESTAMP* to SO/SCM_TIMESTAMP*_OLD. 3. Alter socket options so that SOCK_RCVTSTAMPNS does not rely on SOCK_RCVTSTAMP. 4. Introduce y2038 safe types for socket timestamp. 5. Introduce new y2038 safe socket options SO/SCM_TIMESTAMP*_NEW. 6. Intorduce new y2038 safe socket timeout options. Changes since v4: * Fixed the typo in calling sock_get_timeout() Changes since v3: * Rebased onto net-next and fixups as per review comments * Merged the socket timeout series * Integrated Arnd's patch to simplify compat handling of timeout syscalls Changes since v2: * Removed extra functions to reduce diff churn as per code review Changes since v1: * Dropped the change to disentangle sock flags * Renamed sock_timeval to __kernel_sock_timeval * Updated a few comments * Added documentation changes ==================== Signed-off-by: David S.

The subsequent patches in the series add support for new socket timeout options with _NEW suffix that will use y2038 safe data structures. Although the existing struct timeval layout is sufficiently wide to represent timeouts, because of the way libc will interpret time_t based on user defined flag, these new flags provide a way of having a structure that is the same for all architectures consistently. Rename the existing options with _OLD suffix forms so that the right option is enabled for userspace applications according to the architecture and time_t definition of libc.

* net: phy: realtek: add generic Realtek PHY driverHeiner Kallweit2019-02-031-0/+9
| | | | | | | | | | | | | | The integrated PHY's of later RTL8168 network chips report the generic PHYID 0x001cc800 (Realtek OUI, model and revision number both set to zero) and therefore currently the genphy driver is used. To be able to use the paged version of e.g. phy_write() we need a PHY driver with the read_page and write_page callbacks implemented. So basically make a copy of the genphy driver, just with the read_page and write_page callbacks being set. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.
