2024-05-07net: annotate writes on dev->mtu from ndo_change_mtu()Eric Dumazet1-1/+1
Simon reported that ndo_change_mtu() methods were never updated to use WRITE_ONCE(dev->mtu, new_mtu) as hinted in commit 501a90c94510 ("inet: protect against too small mtu values.") We read dev->mtu without holding RTNL in many places, with READ_ONCE() annotations. It is time to take care of ndo_change_mtu() methods to use corresponding WRITE_ONCE() Signed-off-by: Eric Dumazet <edumazet@google.com> Reported-by: Simon Horman <horms@kernel.org> Closes: https://lore.kernel.org/netdev/20240505144608.GB67882@kernel.org/ Reviewed-by: Jacob Keller <jacob.e.keller@intel.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Reviewed-by: Simon Horman <horms@kernel.org> Acked-by: Shannon Nelson <shannon.nelson@amd.com> Link: https://lore.kernel.org/r/20240506102812.3025432-1-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2021-07-27dev_ioctl: split out ndo_eth_ioctlArnd Bergmann1-1/+1
Most users of ndo_do_ioctl are ethernet drivers that implement the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP. Separate these from the few drivers that use ndo_do_ioctl to implement SIOCBOND, SIOCBR and SIOCWANDEV commands. This is a purely cosmetic change intended to help readers find their way through the implementation.

2018-05-25cxgb4/cxgb4vf: Notify link changes to OS-dependent codeArjun Vynipadath1-3/+2
We have a confusion of two different abstractions in the Common Code: Physical Link (Port) and Logical Network Interface (Virtual Interface), and we haven't been properly managing the state of the intersection of those two abstractions. On the one hand we have the Physical state of the Link -- up or down -- and on the other we have the logical state of the VI, enabled or not. {ethN} refers to both the Physical and Logical State. In this case, ifconfig only affects/interrogates the Logical State of a VI, and ethtool only deals with the Physical State. And these are different. So, just because we disable the VI, we don't really want to change the Physical Link Up/Down state. Thus, the previous hack to set "lc->link_ok = 0" when we disable a VI is completely incorrect. Where we get into trouble is where the Physical Link State and the Logical VI State cross swords. And that happens in t4_handle_get_port_info() where we need to manage/safe the Physical Link State, but we also need to know when the Logical VI State has changed and pass that back up to the OS-dependent Driver routine t4_os_link_changed() which is concerned about the Logical Interface. So we enable a VI and that causes Firmware to send us a new Port Information message, but if none of the Physical Link State particulars have changed, we don't call t4_os_link_changed(). This fix uses the existing OS Contract APIs for the Common Code to inform the OS-dependent portion of the Host Driver when the "Link" (really Logical Network Interface) is "up" or "down". A new API t4_enable_pi_params() is added which calls t4_enable_vi_params() and, if that is successful, then calls back to the OS Contract API t4_os_link_changed() notifying the OS-dependent layer of the potential Link State change.

2018-03-04cxgb4vf: Forcefully link up virtual interfacesArjun Vynipadath1-3/+11
The Virtual Interfaces are connected to an internal switch on the chip which allows VIs attached to the same port to talk to each other even when the port link is down. As a result, we generally want to always report a VI's link as being "up".
