* net/macb: fix capabilities configurationNicolas Ferre2015-03-311-18/+18
| | | | | | | | | | | | | | Capabilities configuration by macb_configure_caps() was moved far too late by 421d9df0628b (net/macb: merge at91_ether driver into macb driver) which would lead to badly configured hardware. So, move this function to early probe and modify its prototype to re-gain its original behavior. DT data retrieval is also moved to simplify the probe code flow.

* net/macb: only probe queues once and use stored valuesNicolas Ferre2015-03-312-4/+4
| | | | | | | | | | | | | | When merging at91_ether and macb driver during 421d9df0628b (net/macb: merge at91_ether driver into macb driver) the probe function has been split. The code dealing with initialization of queues is now moved in macb_init() which needs information computed in the parent macb_probe() function. So, add the queue_mask information to the private structure and use it when needed in macb_init().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will expose in /sys whether the ifname of a device is set by userspace or generated by the kernel. The latter kind (wlanX, etc) is not deterministic, so userspace needs to rename these devices to names that are guaranteed to stay the same between reboots. The former, however should never be renamed, so userspace needs to be able to reliably tell the difference.

| * mac80211_hwsim: fix beacon timersJohannes Berg2015-03-041-9/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Jouni reported that certain combinations of hwsim test cases failed, and we found that beaconing was erroneously enabled too early on any channel switch, which lead to the BI of 2000 TU from the first test case to leak into the second one, which then didn't beacon properly. To fix this, set data->beacon_int to zero when all stop beaconing so that beaconing cannot be started (which was intended as 'restarted') elsewhere. Additionally, Jouni found that due to this 'restart' and the beacon interval handling station interfaces would also have a needlessly running beacon timer all the time, of course not doing anything. To also fix the latter case only use the beacon interval when it's actually needed, i.e. when beaconing gets enabled.

These changes make it easier for drivers to add ifindex indication in vendor events cleanly.

| * cfg80211: add bss_type and privacy arguments in cfg80211_get_bss()Dedy Lansky2015-03-036-15/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 802.11ad adds new a network type (PBSS) and changes the capability field interpretation for the DMG (60G) band. The same 2 bits that were interpreted as "ESS" and "IBSS" before are re-used as a 2-bit field with 3 valid values (and 1 reserved). Valid values are: "IBSS", "PBSS" (new) and "AP". In order to get the BSS struct for the new PBSS networks, change the cfg80211_get_bss() function to take a new enum ieee80211_bss_type argument with the valid network types, as "capa_mask" and "capa_val" no longer work correctly (the search must be band-aware now.) The remaining bits in "capa_mask" and "capa_val" are used only for privacy matching so replace those two with a privacy enum as well.

| * cfg80211-wext: export symbols only when neededJohannes Berg2015-02-282-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When a fully converted cfg80211 driver needs cfg80211-wext for userspace API purposes, the symbols need not be exported. When other drivers (orinoco/hermes or ipw2200) are enabled, they do need the symbols exported as they use them directly. Make those drivers select a new CFG80211_WEXT_EXPORT Kconfig symbol (instead of just CFG80211_WEXT) and export the functions only if requested - this saves about 1/2k due to the size of EXPORT_SYMBOL() itself.

So to solve this I cases the arguments to "long long". -DaveM Richard Cochran says: ==================== ptp: get ready for 2038 This series converts the core driver methods of the PTP Hardware Clock (PHC) subsystem to use the 64 bit version of the timespec structure, making the core API ready for the year 2038. In addition, I reviewed how each driver and device represents the time value at the hardware register level. Most of the drivers are ready, but a few will need some work before the year 2038, as shown: Patch Driver ------------------------------------------------ 12 drivers/net/ethernet/intel/igb/igb_ptp.c 15 ? drivers/net/ethernet/sfc/ptp.c 16 drivers/net/ethernet/stmicro/stmmac/stmmac_ptp.c The commit log messages document how each driver is ready or why it is not ready. For patch 15, I could not easily find out the hardware representation of the time value, and so the SFC maintainers will have to review their low level code in order to resolve any remaining issues. * ChangeLog ** V3 - dp83640: use timespec64 throughout per Arnd's suggestion - tilegx: use timespec64 throughout per Chris' suggestion - add Jeff's acked-bys ** V2 - use the new methods in the posix clock code right away (patch #3) ==================== Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All of the PHC drivers have been converted to the new methods. This patch converts the three remaining callers within the core code and removes the older methods for good. As a result, the core PHC code is ready for the year 2038. However, some of the PHC drivers are not quite ready yet. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This device stores the number of seconds in a 32 bit register, and the stored value is unsigned. Therefore this driver and device are ready for the year 2038. However, more work will be needed prior to 2106. Compile tested only.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver is 64 bit only, and so this driver and device are ready for 2038. This patch changes the driver to the new PHC and also carries the timespec64 parameter on out to the gxio_mpipe_get- set_timestamp functions, making explicit the fact that the tv_sec field is 64 bits wide.
