2022-08-31net: ethernet: move from strlcpy with unused retval to strscpyWolfram Sang1-3/+3
Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

2021-07-27dev_ioctl: split out ndo_eth_ioctlArnd Bergmann2-2/+2
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.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances.

2020-04-23net: meth: remove spurious copyright textJonathan Corbet1-16/+0
Evidently, at some point in the pre-githistorious past, drivers/net/ethernet/sgi/meth.h somehow contained some code from the "snull" driver from the Linux Device Drivers book. A comment crediting that source, asserting copyright ownership by the LDD authors, and imposing the LDD2 license terms was duly added to the file. Any code that may have been derived from snull is long gone, and the distribution terms are not GPL-compatible. Since the copyright claim is not based in fact (if it ever was), simply remove it and the distribution terms as well.

2020-01-09mfd: ioc3: Add driver for SGI IOC3 chipThomas Bogendoerfer2-461/+100
SGI IOC3 chip has integrated ethernet, keyboard and mouse interface. It also supports connecting a SuperIO chip for serial and parallel interfaces. IOC3 is used inside various SGI systemboards and add-on cards with different equipped external interfaces. Support for ethernet and serial interfaces were implemented inside the network driver. This patchset moves out the not network related parts to a new MFD driver, which takes care of card detection, setup of platform devices and interrupt distribution for the subdevices.

2020-01-09MIPS: SGI-IP27: fix readb/writeb addressingThomas Bogendoerfer1-0/+12
Our chosen byte swapping, which is what firmware already uses, is to do readl/writel by normal lw/sw intructions (data invariance). This also means we need to mangle addresses for u8 and u16 accesses. The mangling for 16bit has been done aready, but 8bit one was missing. Correcting this causes different addresses for accesses to the SuperIO and local bus of the IOC3 chip. This is fixed by changing byte order in ioc3 and m48rtc_rtc structs.

2017-10-18net/ethernet/sgi: Convert timers to use timer_setup()Kees Cook1-5/+3
In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.

2017-07-15ioc3-eth: store pointer to net_device for priviate areaJason A. Donenfeld1-9/+5
Computing the alignment manually for going from priv to pub is probably not such a good idea, and in general the assumption that going from priv to pub is possible trivially could change, so rather than relying on that, we change things to just store a pointer to pub.

2017-03-06net: sgi: ioc3-eth: use new api ethtool_{get|set}_link_ksettingsPhilippe Reynes1-6/+8
The ethtool api {get|set}_settings is deprecated. We move this driver to new api {get|set}_link_ksettings. As I don't have the hardware, I'd be very pleased if someone may test this patch. Signed-off-by: Philippe Reynes <tremyfr@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-03-02drivers: net: ethernet: remove incorrect __exit markupsDmitry Torokhov1-2/+2
Even if bus is not hot-pluggable, devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes.

2017-02-22lib/show_mem.c: teach show_mem to work with the given nodemaskMichal Hocko1-1/+1
show_mem() allows to filter out node specific data which is irrelevant to the allocation request via SHOW_MEM_FILTER_NODES. The filtering is done in skip_free_areas_node which skips all nodes which are not in the mems_allowed of the current process. This works most of the time as expected because the nodemask shouldn't be outside of the allocating task but there are some exceptions. E.g. memory hotplug might want to request allocations from outside of the allowed nodes (see new_node_page). Get rid of this hardcoded behavior and push the allocation mask down the show_mem path and use it instead of cpuset_current_mems_allowed. NULL nodemask is interpreted as cpuset_current_mems_allowed.

2016-10-13net: deprecate eth_change_mtu, remove usageJarod Wilson2-2/+0
With centralized MTU checking, there's nothing productive done by eth_change_mtu that isn't already done in dev_set_mtu, so mark it as deprecated and remove all usage of it in the kernel. All callers have been audited for calls to alloc_etherdev* or ether_setup directly, which means they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu prints out a netdev_warn about being deprecated, for the benefit of out-of-tree drivers that might be utilizing it. Of note, dvb_net.c actually had dev->mtu = 4096, while using eth_change_mtu, meaning that if you ever tried changing it's mtu, you couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set to 4096 to remedy that. v2: fix up lantiq_etop, missed breakage due to drive not compiling on x86 CC: netdev@vger.kernel.org Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: David S.
