2019-08-06net: tc_act: add skbedit_ptype helper functionsJohn Hurley
The tc_act header file contains an inline function that checks if an action is changing the skb mark of a packet and a further function to extract the mark. Add similar functions to check for and get skbedit actions that modify the packet type of the skb.

2019-08-06Merge branch '100GbE' of ↵David S. Miller
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2019-08-04 This series contains more updates to fm10k from Jake Keller. Jake removes the unnecessary initialization of some variables to help resolve static code checker warnings. Explicitly return success during resume, since the value of 'err' is always success. Fixed a issue with incrementing a void pointer, which can produce undefined behavior. Used the __always_unused macro for function templates that are passed as parameters in functions, but are not used. Simplified the code by removing an unnecessary macro in determining the value of NON_Q_VECTORS. Fixed an issue, using bitwise operations to prevent the low address overwriting the high portion of the address. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2019-08-06fq_codel: Kill useless per-flow dropped statisticDave Taht
It is almost impossible to get anything other than a 0 out of flow->dropped statistic with a tc class dump, as it resets to 0 on every round. It also conflates ecn marks with drops. It would have been useful had it kept a cumulative drop count, but it doesn't. This patch doesn't change the API, it just stops tracking a stat and state that is impossible to measure and nobody uses. Signed-off-by: Dave Taht <dave.taht@gmail.com> Signed-off-by: David S.

2019-08-06Increase fq_codel count in the bulk dropperDave Taht
In the field fq_codel is often used with a smaller memory or packet limit than the default, and when the bulk dropper is hit, the drop pattern bifircates into one that more slowly increases the codel drop rate and hits the bulk dropper more than it should. The scan through the 1024 queues happens more often than it needs to. This patch increases the codel count in the bulk dropper, but does not change the drop rate there, relying on the next codel round to deliver the next packet at the original drop rate (after that burst of loss), then escalate to a higher signaling rate.

2019-08-06net: dsa: dump CPU port regs through masterVivien Didelot
Merge the CPU port registers dump into the master interface registers dump through ethtool, by nesting the ethtool_drvinfo and ethtool_regs structures of the CPU port into the dump. drvinfo->regdump_len will contain the full data length, while regs->len will contain only the master interface registers dump length. This allows for example to dump the CPU port registers on a ZII Dev C board like this: # ethtool -d eth1 0x004: 0x00000000 0x008: 0x0a8000aa 0x010: 0x01000000 0x014: 0x00000000 0x024: 0xf0000102 0x040: 0x6d82c800 0x044: 0x00000020 0x064: 0x40000000 0x084: RCR (Receive Control Register) 0x47c00104 MAX_FL (Maximum frame length) 1984 FCE (Flow control enable) 0 BC_REJ (Broadcast frame reject) 0 PROM (Promiscuous mode) 0 DRT (Disable receive on transmit) 0 LOOP (Internal loopback) 0 0x0c4: TCR (Transmit Control Register) 0x00000004 RFC_PAUSE (Receive frame control pause) 0 TFC_PAUSE (Transmit frame control pause) 0 FDEN (Full duplex enable) 1 HBC (Heartbeat control) 0 GTS (Graceful transmit stop) 0 0x0e4: 0x76735d6d 0x0e8: 0x7e9e8808 0x0ec: 0x00010000 . . . 88E6352 Switch Port Registers ------------------------------ 00: Port Status 0x4d04 Pause Enabled 0 My Pause 1 802.3 PHY Detected 0 Link Status Up Duplex Full Speed 100 or 200 Mbps EEE Enabled 0 Transmitter Paused 0 Flow Control 0 Config Mode 0x4 01: Physical Control 0x003d RGMII Receive Timing Control Default RGMII Transmit Timing Control Default 200 BASE Mode 100 Flow Control's Forced value 0 Force Flow Control 0 Link's Forced value Up Force Link 1 Duplex's Forced value Full Force Duplex 1 Force Speed 100 or 200 Mbps . . .

2019-08-04fm10k: fix fm10k_get_fault_pf to read correct addressJacob Keller
Fix assignment of the FM10K_FAULT_ADDR_LO register into fault->address by using a bit-wise |= operation. Without this, the low address is completely overwriting the high potion of the address. This caused the fault to incorrectly return only the lower 32 bits of the fault address. This issue was detected by cppcheck and resolves the following warnings produced by that tool: [fm10k_pf.c:1668] -> [fm10k_pf.c:1670]: (style) Variable 'fault->address' is reassigned a value before the old one has been used.

2019-08-04fm10k: convert NON_Q_VECTORS(hw) into NON_Q_VECTORSJacob Keller
The driver currently uses a macro to decide whether we should use NON_Q_VECTORS_PF or NON_Q_VECTORS_VF. However, we also define NON_Q_VECTORS_VF to the same value as NON_Q_VECTORS_PF. This means that the macro NON_Q_VECTORS(hw) will always return the same value. Let's just remove this macro, and replace it directly with an enum value on the enum non_q_vectors. This was detected by cppcheck and fixes the following warnings when building with BUILD=KERNEL [fm10k_ethtool.c:1123]: (style) Same value in both branches of ternary operator.

Setup includes unreachable routes and fib rules blocking traffic. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2019-08-03selftests: Add nettestDavid Ahern
Add nettest - a simple program with an implementation for various networking APIs. nettest is used for tcp, udp and raw functional tests for both IPv4 and IPv6. Point of this command versus existing utilities: - controlled implementation of the APIs and the order in which they are called, - ability to verify ingress device, local and remote addresses, - timeout for controlled test length, - ability to discriminate a timeout from a system call failure, and - simplicity with test scripts. The command returns: 0 on success, 1 for any system call failure, and 2 on timeout. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2019-08-02Merge branch 'enetc-PCIe-MDIO'David S. Miller
Claudiu Manoil says: ==================== enetc: Add mdio bus driver for the PCIe MDIO endpoint First patch fixes a sparse issue and cleans up accessors to avoid casting to __iomem. The second one cleans up the Makefile, to make it easier to add new entries. Third patch just registers the PCIe endpoint device containing the MDIO registers as a standalone MDIO bus driver, to provide an alternative way to control the MDIO bus. The same code used by the ENETC ports (eth controllers) to manage MDIO via local registers applies and is reused. Bindings are provided for the new MDIO node, similarly to ENETC port nodes bindings. Last patch enables the ENETC port 1 and its RGMII PHY on the LS1028A QDS board, where the MDIO muxing configuration relies on the MDIO support provided in the first patch. Changes since v0: v1 - fixed mdio bus allocation v2 - cleaned up accessors to avoid casting v3 - fixed spelling (mostly commit message) v4 - fixed err path check blunder v5 - fixed loadble module build, provided separate kbuild module for the driver ==================== Signed-off-by: David S.
