* Use an accessor function to access ifr_data.Brooks Davis2018-03-301-2/+2
| | | | | | | | | | | | | | | | This fixes 32-bit compat (no ioctl command defintions are required as struct ifreq is the same size). This is believed to be sufficent to fully support ifconfig on 32-bit systems.

* [net80211] convert all of the WME use over to a temporary copy of WME info.Adrian Chadd2018-01-021-1/+5
| | | | | | | | | | | | | | | | | | | | This removes the direct WME info access in the ieee80211com struct and instead provides a method of fetching the data. Right now it's a no-op but eventually it'll turn into a per-VAP method for drivers that support it (eg iwn, iwm, upcoming ath10k work) as things like p2p support require this kind of behaviour. Tested: * ath(4), STA and AP mode TODO: * yes, this is slightly stack size-y, but it is an important first step to get drivers migrated over to a sensible WME API. A lot of per-phy things need to be converted to per-VAP before P2P, 11ac firmware, etc stuff shows up. Notes: svn path=/head/; revision=327479

* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-278-0/+16
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255
* Shorten list of arguments to mbuf external storage freeing function.Gleb Smirnoff2017-10-091-5/+5
| | | | | | | | | | | | | | | | | | | | All of these arguments are stored in m_ext, so there is no reason to pass them in the argument list. Not all functions need the second argument, some don't even need the first one. The second argument lives in next cache line, so not dereferencing it is a performance gain. This was discovered in sendfile(2), which will be covered by next commits. The second goal of this commit is to bring even more flexibility to m_ext mbufs, allowing to create more fields in m_ext, opaque to the generic mbuf code, and potentially set and dereferenced by subsystems.

* Replay r286410. Change KPI of how device drivers that provide wirelessGleb Smirnoff2015-08-273-312/+204
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl.

* Extend the meaning of the CTLFLAG_TUN flag to automatically check ifHans Petter Selasky2014-06-271-12/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | there is an environment variable which shall initialize the SYSCTL during early boot. This works for all SYSCTL types both statically and dynamically created ones, except for the SYSCTL NODE type and SYSCTLs which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to be used in the case a tunable sysctl has a custom initialisation function allowing the sysctl to still be marked as a tunable. The kernel SYSCTL API is mostly the same, with a few exceptions for some special operations like iterating childrens of a static/extern SYSCTL node. This operation should probably be made into a factored out common macro, hence some device drivers use this. The reason for changing the SYSCTL API was the need for a SYSCTL parent OID pointer and not only the SYSCTL parent OID list pointer in order to quickly generate the sysctl path. The motivation behind this patch is to avoid parameter loading cludges inside the OFED driver subsystem. Instead of adding special code to the OFED driver subsystem to post-load tunables into dynamically created sysctls, we generalize this in the kernel. Other changes: - Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask" to "hw.pcic.intr_mask". - Removed redundant TUNABLE statements throughout the kernel. - Some minor code rewrites in connection to removing not needed TUNABLE statements. - Added a missing SYSCTL_DECL(). - Wrapped two very long lines. - Avoid malloc()/free() inside sysctl string handling, in case it is called to initialize a sysctl from a tunable, hence malloc()/free() is not ready when sysctls from the sysctl dataset are registered. - Bumped FreeBSD version to indicate SYSCTL API change.

The lazy BAR allocation code in FreeBSD sometimes disables this bit when it detects a range conflict, and will re-enable it on demand when a driver allocates the BAR. Thus, the bit is no longer a reliable indication of capability, and should not be checked. This results in the elimination of a lot of code from drivers, and also gives the opportunity to simplify a lot of drivers to use a helper API to set the busmaster enable bit. This changes fixes some recent reports of disk controllers and their associated drives/enclosures disappearing during boot.
