net: phy: micrel: add 125MHz reference clock workaround

2018-05-16T16:20:03+00:00

The micrel KSZ9031 phy has a optional clock pin (CLK125_NDO) which can be used as reference clock for the MAC unit. The clock signal must meet the RGMII requirements to ensure the correct data transmission between the MAC and the PHY. The KSZ9031 phy does not fulfill the duty cycle requirement if the phy is configured as slave. For a complete describtion look at the errata sheets: DS80000691D or DS80000692D. The errata sheet recommends to force the phy into master mode whenever there is a 1000Base-T link-up as work around. Only set the "micrel,force-master" property if you use the phy reference clock provided by CLK125_NDO pin as MAC reference clock in your application. Attenation, this workaround is only usable if the link partner can be configured to slave mode for 1000Base-T.

net: phy: micrel: Use strlcpy() for ethtool::get_strings

2018-03-06T16:12:39+00:00

Our statistics strings are allocated at initialization without being bound to a specific size, yet, we would copy ETH_GSTRING_LEN bytes using memcpy() which would create out of bounds accesses, this was flagged by KASAN. Replace this with strlcpy() to make sure we are bound the source buffer size and we also always NUL-terminate strings.

net/ipv6/ip6_gre.c is a case of parallel adds. include/trace/events/tcp.h is a little bit more tricky. The removal of in-trace-macro ifdefs in 'net' paralleled with moving show_tcp_state_name and friends over to include/trace/events/sock.h in 'net-next'. Signed-off-by: David S. Miller

net: phy: micrel: ksz9031: reconfigure autoneg after phy autoneg workaround

2017-12-26T17:26:43+00:00

Under some circumstances driver will perform PHY reset in ksz9031_read_status() to fix autoneg failure case (idle error count = 0xFF). When this happens ksz9031 will not detect link status change any more when connecting to Netgear 1G switch (link can be recovered sometimes by restarting netdevice "ifconfig down up"). Reproduced with TI am572x board equipped with ksz9031 PHY while connecting to Netgear 1G switch. Fix the issue by reconfiguring autonegotiation after PHY reset in ksz9031_read_status().

net/phy: micrel: configure intterupts after autoneg workaround

2017-06-22T15:05:16+00:00

The commit ("net/phy: micrel: Add workaround for bad autoneg") fixes an autoneg failure case by resetting the hardware. This turns off intterupts. Things will work themselves out if the phy polls, as it will figure out it's state during a poll. However if the phy uses only intterupts, the phy will stall, since interrupts are off. This patch fixes the issue by calling config_intr after resetting the phy.
