2019-02-03socket: Add SO_TIMESTAMP[NS]_NEWDeepa Dinamani12-32/+171
Add SO_TIMESTAMP_NEW and SO_TIMESTAMPNS_NEW variants of socket timestamp options. These are the y2038 safe versions of the SO_TIMESTAMP_OLD and SO_TIMESTAMPNS_OLD for all architectures. Note that the format of scm_timestamping.ts[0] is not changed in this patch.

2019-02-03socket: Add struct __kernel_sock_timevalDeepa Dinamani1-0/+5
The new type is meant to be used as a y2038 safe structure to be used as part of cmsg data. Presently the SO_TIMESTAMP socket option uses struct timeval for timestamps. This is not y2038 safe. Subsequent patches in the series add new y2038 safe socket option to be used in the place of SO_TIMESTAMP_OLD. struct __kernel_sock_timeval will be used as the timestamp format at that time. struct __kernel_sock_timeval also maintains the same layout across 32 bit and 64 bit ABIs.

2019-02-03socket: Use old_timeval types for socket timestampsDeepa Dinamani7-12/+12
As part of y2038 solution, all internal uses of struct timeval are replaced by struct __kernel_old_timeval and struct compat_timeval by struct old_timeval32. Make socket timestamps use these new types. This is mainly to be able to verify that the kernel build is y2038 safe when such non y2038 safe types are not supported anymore.

2019-02-03sockopt: Rename SO_TIMESTAMP* to SO_TIMESTAMP*_OLDDeepa Dinamani12-57/+101
SO_TIMESTAMP, SO_TIMESTAMPNS and SO_TIMESTAMPING options, the way they are currently defined, are not y2038 safe. Subsequent patches in the series add new y2038 safe versions of these options which provide 64 bit timestamps on all architectures uniformly. Hence, rename existing options with OLD tag suffixes. Also note that kernel will not use the untagged SO_TIMESTAMP* and SCM_TIMESTAMP* options internally anymore.

2019-02-03socket: move compat timeout handling into sock.cArnd Bergmann3-89/+46
This is a cleanup to prepare for the addition of 64-bit time_t in O_SNDTIMEO/O_RCVTIMEO. The existing compat handler seems unnecessarily complex and error-prone, moving it all into the main setsockopt()/getsockopt() implementation requires half as much code and is easier to extend. 32-bit user space can now use old_timeval32 on both 32-bit and 64-bit machines, while 64-bit code can use __old_kernel_timeval.

Jakub Kicinski says: ==================== devlink: add device (driver) information API fw_version field in ethtool -i does not suit modern needs with 31 characters being quite limiting on more complex systems. There is also no distinction between the running and flashed versions of the firmware. Since the driver information pertains to the entire device, rather than a particular netdev, it seems wise to move it do devlink, at the same time fixing the aforementioned issues. The new API allows exposing the device serial number and versions of the components of the card - both hardware, firmware (running and flashed). Driver authors can choose descriptive identifiers for the version fields. A few version identifiers which seemed relevant for most devices have been added to the global devlink header. Example: $ devlink dev info pci/0000:05:00.0 pci/0000:05:00.0: driver nfp serial_number 16240145 versions: fixed: board.id AMDA0099-0001 board.rev 07 board.vendor SMA board.model carbon running: fw.mgmt: 010156.010156.010156 fw.cpld: 0x44 fw.app: sriov-2.1.16 stored: fw.mgmt: 010158.010158.010158 fw.cpld: 0x44 fw.app: sriov-2.1.20 Last patch also includes a compat code for ethtool.

2019-02-02devlink: add version reporting to devlink info APIJakub Kicinski3-0/+95
ethtool -i has a few fixed-size fields which can be used to report firmware version and expansion ROM version. Unfortunately, modern hardware has more firmware components. There is usually some datapath microcode, management controller, PXE drivers, and a CPLD load. Running ethtool -i on modern controllers reveals the fact that vendors cram multiple values into firmware version field. Here are some examples from systems I could lay my hands on quickly: tg3: "FFV20.2.17 bc 5720-v1.39" i40e: "6.01 0x800034a4 1.1747.0" nfp: "0.0.3.5 0.25 sriov-2.1.16 nic" Add a new devlink API to allow retrieving multiple versions, and provide user-readable name for those versions. While at it break down the versions into three categories: - fixed - this is the board/fixed component version, usually vendors report information like the board version in the PCI VPD, but it will benefit from naming and common API as well; - running - this is the running firmware version; - stored - this is firmware in the flash, after firmware update this value will reflect the flashed version, while the running version may only be updated after reboot. v3: - add per-type helpers instead of using the special argument (Jiri). RFCv2: - remove the nesting in attr DEVLINK_ATTR_INFO_VERSIONS (now versions are mixed with other info attrs)l - have the driver report versions from the same callback as other info.

2019-02-02Merge branch 'selftests-Various-fixes'David S. Miller10-21/+107
Petr Machata says: ==================== selftests: Various fixes This patch set contains various fixes whose common denominator is improving quality of forwarding and mlxsw selftests. Most of the fixes are improvements in determinism (such that timing and latency don't impact the test performance). These were prompted by regular runs of the test suite on a hardware emulator, the performance of which is necessarily lower than that of the real device. Patches #1 (from Ido), #2 and #3 make changes to ping limits. Patches #4 and #5 add more sleep in places where things need more time to finish. Patches #6 and #7 fix two tests in the suite of mirror-to-gretap tests where underlay involves a VLAN device over an 802.1q bridge. Patches #8, #9 and #10 fix bugs in mirror-to-gretap test where underlay involves a LAG device. Patch #11 fixes a missed RET initialization in mirror-to-gretap flower test. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-02selftests: forwarding: mirror_gre_flower: Fix test result handlingPetr Machata1-2/+2
The global variable RET needs to be initialized before each call to log_test. This test case sets it once before running the tests, but then calls log_tests for every individual test. Thus a failure in one of the tests causes spurious failures in follow-up tests as well. Fix by moving the initialization of RET from test_all() to full_test_span_gre_dir_acl(), a function that implements the test. Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S.

2019-02-02selftests: forwarding: mirror_gre_bridge_1q_lag: Ignore ARPPetr Machata1-1/+5
This test sets up mirroring such that it mirrors all overlay traffic. That includes ARP, which causes occasional miscounts and spurious failures. Ignore ARP explicitly to avoid these problems. Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-02selftests: forwarding: mirror_gre_bridge_1q_lag: Enable forwardingPetr Machata1-0/+4
This test relies on routing in the primary traffic path, but neglects to enable forwarding. Do so. Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-02selftests: forwarding: mirror_gre_bridge_1q_lag: Flush neighborsPetr Machata1-0/+1
After one LAG slave is downed and another upped, it takes a while for the neighbor on a bridge to time out and get renegotiated. The test does prompt update of FDB entries by arpinging. But because the neighbor still references another address, offloading is not possible, and some packets may end up not being mirrored. To force the neighbor renegotiation, simply flush the neighbor table at the bridge. Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
