* once: make helper generic for calling functions onceHannes Frederic Sowa2015-10-081-14/+47
| | | | | | | | | | | | | | | | | | Make the get_random_once() helper generic enough, so that functions in general would only be called once, where one user of this is then net_get_random_once(). The only implementation specific call is to get_random_bytes(), all the rest of this *_once() facility would be duplicated among different subsystems otherwise. The new DO_ONCE() helper will be used by prandom() later on, but might also be useful for other scenarios/subsystems as well where a one-time initialization in often-called, possibly fast path code could occur.

* net: move net_get_random_once to libHannes Frederic Sowa2015-10-082-17/+28
| | | | | | | | | | | | There's no good reason why users outside of networking should not be using this facility, f.e. for initializing their seeds. Therefore, make it accessible from there as get_random_once().

* net: phy: Broadcom Cygnus internal Etherent PHY driverArun Parameswaran2015-10-081-0/+7
| | | | | | | | | | | | | | | | | | Add support for the Broadcom Cygnus SoCs internal PHY's. The PHYs are 1000M/100M/10M capable with support for 'EEE' and 'APD' (Auto Power Down). This driver supports the following Broadcom Cygnus SoCs: - BCM583XX (BCM58300, BCM58302, BCM58303, BCM58305) - BCM113XX (BCM11300, BCM11320, BCM11350, BCM11360) The PHY's on these SoC's require some workarounds for stable operation, both during configuration time and during suspend/resume. This driver handles the application of the workarounds. Signed-off-by: Arun Parameswaran <arunp@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, cfg80211 rejects capability updates for existing entries and as a result it's impossible to update entries that were added unassociated, but that is necessary to go through the full station states from userspace, adding a station before authentication etc. Fix this by allowing updates to capabilities for stations that the driver (or mac80211) assigned unassociated state. Drivers setting the full station state support flag must use the new station type for proper operation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When debugging wireless powersave issues on the AP side it's quite helpful to see our own beacons that are transmitted by the hardware/driver. However, this is not that easy since beacons don't pass through the regular TX queues. Preferably drivers would call ieee80211_tx_status also for tx'ed beacons but that's not always possible. Hence, just send a copy of each beacon generated by ieee80211_beacon_get_tim to monitor devices when they are getting fetched by the driver. Also add a HW flag IEEE80211_HW_BEACON_TX_STATUS that can be used by drivers to indicate that they report TX status for beacons.

To prepare for this, simply extend the bpf_prog_create_from_user() API to hold a flag that tells whether we should store the original or not. Also, fanout filters could make use of that in future for things like diag. While fanout filters already use bpf_prog_destroy(), move seccomp over to them as well to handle original programs when present.
