The SIOCGSTAMP/SIOCGSTAMPNS ioctl commands are implemented by many socket protocol handlers, and all of those end up calling the same sock_get_timestamp()/sock_get_timestampns() helper functions, which results in a lot of duplicate code. With the introduction of 64-bit time_t on 32-bit architectures, this gets worse, as we then need four different ioctl commands in each socket protocol implementation. To simplify that, let's add a new .gettstamp() operation in struct proto_ops, and move ioctl implementation into the common sock_ioctl()/compat_sock_ioctl_trans() functions that these all go through. We can reuse the sock_get_timestamp() implementation, but generalize it so it can deal with both native and compat mode, as well as timeval and timespec structures.

Mike Manning says: ==================== net: support binding vlan dev link state to vlan member bridge ports For vlan filtering on bridges, the bridge may also have vlan devices as upper devices. For switches, these are used to provide L3 packet processing for ports that are members of a given vlan. While it is correct that the admin state for these vlan devices is either set directly for the device or inherited from the lower device, the link state is also transferred from the lower device. So this is always up if the bridge is in admin up state and there is at least one bridge port that is up, regardless of the vlan that the port is in. The link state of the vlan device may need to track only the state of the subset of ports that are also members of the corresponding vlan, rather than that of all ports. This series provides an optional vlan flag so that the link state of the vlan device is only up if there is at least one bridge port that is up AND is a member of the corresponding vlan. v2: - Address review comments from Nikolay Aleksandrov in patches 3 & 4 and add patch 5 to address bridge link down due to STP v3: - Address review comment from Nikolay Aleksandrov in patch 4 so as to remove unnecessary inline #ifdef ==================== Signed-off-by: NDavid S.

If vlan bridge binding is enabled, then the link state of a vlan device that is an upper device of the bridge tracks the state of bridge ports that are members of that vlan. But this can only be done when the link state of the bridge is up. If it is down, then the link state of the vlan devices must also be down. This is to maintain existing behavior for when STP is enabled and there are no live ports, in which case the link state for the bridge and any vlan devices is down.

If vlan bridge binding is enabled, then the link state of a vlan device that is an upper device of the bridge should track the state of bridge ports that are members of that vlan. So if a bridge port becomes or stops being a member of a vlan, then update the link state of the vlan device if necessary.

In the case of vlan filtering on bridges, the bridge may also have the corresponding vlan devices as upper devices. A vlan bridge binding mode is added to allow the link state of the vlan device to track only the state of the subset of bridge ports that are also members of the vlan, rather than that of all bridge ports. This mode is set with a vlan flag rather than a bridge sysfs so that the 8021q module is aware that it should not set the link state for the vlan device. If bridge vlan is configured, the bridge device event handling results in the link state for an upper device being set, if it is a vlan device with the vlan bridge binding mode enabled. This also sets a vlan_bridge_binding flag so that subsequent UP/DOWN/CHANGE events for the ports in that bridge result in a link state update of the vlan device if required. The link state of the vlan device is up if there is at least one bridge port that is a vlan member that is admin & oper up, otherwise its oper state is IF_OPER_LOWERLAYERDOWN.

In the case of vlan filtering on bridges, the bridge may also have the corresponding vlan devices as upper devices. Currently the link state of vlan devices is transferred from the lower device. So this is up if the bridge is in admin up state and there is at least one bridge port that is up, regardless of the vlan that the port is a member of. The link state of the vlan device may need to track only the state of the subset of ports that are also members of the corresponding vlan, rather than that of all ports. Add a flag to specify a vlan bridge binding mode, by which the link state is no longer automatically transferred from the lower device, but is instead determined by the bridge ports that are members of the vlan.

David Bauer says: ==================== net: add reset-controller driven PHY reset This patchset adds support for a PHY reset driven by a reset-controller. Currently, only GPIO driven resets are supported by the PHY subsystem. It also renames the reset-gpio from 'reset' to 'reset_gpio' to better differentiate between resets wired to a GPIO and resets wired to a reset-controller driven pin. Some systems have the PHY reset-line wired to a pin controlled by a reset-controller (eg. some Atheros AR9132 based boards). In case the bootloader asserts reset before loading the kernel, we currently do not have a clean way of deasserting reset to probe the PHY. v3: - add missing newline in mdio_bus.c v2: - fixed missed rename of "reset" in at803x.c - move initial reset to mdio_device_reset ==================== Signed-off-by: NDavid S.

To make ICMPv6 closer to ICMPv4, add ratemask parameter. Since the ICMP message types use larger numeric values, a simple bitmask doesn't fit. I use large bitmap. The input and output are the in form of list of ranges. Set the default to rate limit all error messages but Packet Too Big. For Packet Too Big, use ratemask instead of hard-coded. There are functions where icmpv6_xrlim_allow() and icmpv6_global_allow() aren't called. This patch only adds them to icmpv6_echo_reply(). Rate limiting error messages is mandated by RFC 4443 but RFC 4890 says that it is also acceptable to rate limit informational messages. Thus, I removed the current hard-coded behavior of icmpv6_mask_allow() that doesn't rate limit informational messages. v2: Add dummy function proc_do_large_bitmap() if CONFIG_PROC_SYSCTL isn't defined, expand the description in ip-sysctl.txt and remove unnecessary conditional before kfree(). v3: Inline the bitmap instead of dynamically allocated. Still is a pointer to it is needed because of the way proc_do_large_bitmap work. Signed-off-by: NStephen Suryaputra <ssuryaextr@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

In phy_device_create() we set phydev->autoneg = 1. This isn't changed even if the PHY doesn't support autoneg. This seems to affect very few PHY's, and they disable phydev->autoneg in their config_init callback. So it's more of an improvement, therefore net-next. The patch also wouldn't apply to older kernel versions because the link mode bitmaps have been introduced recently. Signed-off-by: NHeiner Kallweit <hkallweit1@gmail.com> Signed-off-by: NDavid S.

Currently when calculating how much to increment ITR by inside of ice_update_itr() we do some estimations and intermediate calculations. Instead of doing estimations, just do the calculation directly. This allows for a more accurate value and it makes it easier for the next person to understand and update. Also, remove the dividing the ITR value by 2 when latency driven because the ITR values are already so low for 100Gbps speed. This should help get to the desired ITR value faster.

This patch adds a new function ice_pf_dcb_cfg (and related helpers) which applies the DCB configuration obtained from the firmware. As part of this, VSIs/netdevs are updated with traffic class information. This patch requires a bit of a refactor of existing code. 1. For a MIB change event, the associated VSI is closed and brought up again. The gap between closing and opening the VSI can cause a race condition. Fix this by grabbing the rtnl_lock prior to closing the VSI and then only free it after re-opening the VSI during a MIB change event. 2. ice_sched_query_elem is used in ice_sched.c and with this patch, in ice_dcb.c as well. However, ice_dcb.c is not built when CONFIG_DCB is unset. This results in namespace warnings (ice_sched.o: Externally defined symbols with no external references) when CONFIG_DCB is unset. To avoid this move ice_sched_query_elem from ice_sched.c to ice_common.c.
