2018-04-28When starting a background scan, free the nodes table to ensure weStefan Sperling
get an up-to-date view of APs around us. In particular, we need to kick out the AP we are associated to. Otherwise, our current AP might stay cached if it is turned off while we are scanning, and we could end up picking a now non-existent but "good looking" AP over and over. found with and ok phessler@
2018-04-28Fix WEP key selection in ieee80211_get_txkey().Stefan Sperling
The WEP key index is stored in ic_def_txkey. The iGTK ("integrity group key") index is specific to WPA. The previous code happened to always select WEP key index 0 since the iGTK index is not yet used by any driver. ok phessler@

2018-04-28Remove redundant error checkkn
error is set by copyinstr(9) only and we return early if it is non-zero, so the loop's last condition is always true. OK deraadt, jca
2018-04-28pgt(4): do not tsleep in the scan ioctl.Paul Irofti
The only action taken during the scan ioctl was to sleep. This does not make sense as the scanning process happens in the state machine behind the scenes. Initialization indeed performs newstate(SCAN), but that is done no matter if the user waits for the full results or not. Instead, this change unifies the (new) user experience when performing ifconfig scan and shows the nodes list produced by the latest background scan. This was not tested on real hardware. Please message me directly in case this broke your card. OK stsp@, deraadt@

Clear group keys in iee80211_newstate only if we're doing WPA. Otherwise, ieee80211_crypto_clear_groupkeys() will clear WEP keys configured by userland before associating. (All WEP keys are group keys.) ok phessler@ tb@ pirofti@

therefore all other x86 cpus must pay the performance price of the hazard workaround until Skylake disappears from the ecosystem eventually like 486. This returns your cpu's performance to pre-inflated performance. ok mlarkin guenther
2018-04-27Introduce an helper function to extract endpoint's max burst value.Martin Pieuchot
Use this helper to calculate the Transfer Burst Count (TBC) and Transfer Last Burst Packet Count (TLBPC) required for isochronous support. Note that SS companion descriptors are still not read. While here print the ETE and IST values in debug mode.

2018-04-27The i.MX8M has the same quirk as the i.MX6SX, where the CAP1 registerPatrick Wildt
spills into the CAP register.
2018-04-27Newer fec(4), like implemented on i.MX8M, have multiple interrupt linesPatrick Wildt
to the ethernet controller for different types of events. On the i.MX8M interrupts only seem to happen on the last interrupt, while the i.MX6 that we support very well only has a single interrupt line. Simply establish all three lines (if available) in a non-MPSAFE fashion to make ethernet work on the i.MX8M SoC. ok kettenis@

2018-04-26net80211: stub SIOCS80211SCAN, make ifconfig scan instant.Paul Irofti
The following removes the functionality of the SIOCS80211SCAN ioctl. After long discussions with stps@, mpi@, and deraadt@ we decided that this was the correct way of fixing ifconfig scan from blocking the network stack. The kernel will continue scanning in the background and filling the nodes array, but ifconfig scan commands will now basically do just a SIOCG80211ALLNODES and pretty print the array. So the output stays the same but is instant. In fact, when the interface is freshly brought up, if you type fast enough, you can see the array being filled by running multiple ifconfig scans in sequence. The SIOCS80211SCAN ioctl stays for now as wi(4), pgt(4) and malo(4) still need it around. But not for long... Another change that this introduces is the fact that ifconfig scan no longer plays with UP and DOWN. If the interface is down it complains and exits. This is needed in order to maintain the nodes list. Works on iwm(4), iwn(4), urtwn(4), run(4) and athn(4). Tested by mpi@, landry@, florian@, thanks! OK mpi@.

2018-04-26vmm(4): remove some unnecessary kernel lock code from the SVM guest loopMike Larkin
that is not needed; this code deals with delaying the relocking of the kernel lock until after interrupts are processed during external interrupt exiting, but this is handled differently on SVM. External interrupts are automatically handled by the CPU as soon as stgi() is performed after exit. (The original code came from the VMX/Intel guest loop.) ok guenther@
2018-04-26Remove solock() surrounding PRU_CONTROL in soo_ioctl().Paul Irofti
