* kmod-sched-cake: bump to latest bake of cake for 17.01Kevin Darbyshire-Bryant2017-12-301-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There has been recent significant activity with the cake qdisc of late but in the cobalt branch. Some of that effort is related to upstreaming to kernel & iproute2 mainline but we're not quite there yet. Relevant feature changes: ingress mode: Instead of only counting packets that make it past the shaper, include packets we've decided to drop as well, since they did arrive with us on the link and took link capacity. This mode is more suitable for shaping the ingress of a link (e.g. from ISP) rather than the more normal egress. ptm mode: Minor optimisation in packet overhead calculation. dual-src/dsthost/triple-isolate: Optimise only calculating src or dst host hashes only if required. ack-filter/ack-filter-aggressive: Filter excessive TCP ACKS. Useful in highly assymetric links (downstream v upstream capacity) where the majority of upstream link capacity is occupied with ACKS for downstream traffic. A separate iproute2 patch to teach it about Cake's new features will follow. Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>

* mac80211: gracefully handle preexisting VIFJo-Philipp Wich2017-12-131-0/+6
| | | | | | | | | | | | | | | | | | | | | Gracefully handle cases where the to-be-created wireless interface already exists on the system which might commonly happen with non-multi-SSID capable wireless drivers. This fixes commit 8301e613655c2d95fa5430a1a57d92d966fdc70b which caused previously ignored "Too many open files in system (-23)" errors to fail the wireless setup procedure. With the updated approach we'll still try recreating the vif after one second if the first attempt to do so failed with ENFILE but we will now consider the operation successfull if a second attempt still yields ENFILE with the requested ifname already existing on the system.

* mac80211: Fix race condition leading to wifi interfaces not coming up at ↵Vittorio Gambaletta2017-12-131-5/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | boot sometimes. In the drv_mac80211_setup function, mac80211_interface_cleanup is called to ask the kernel to delete all existing interfaces for the phy that is being configured via netlink. Later in the first function, mac80211_prepare_vif is called to set up the new interfaces as required. But sometimes, when mac80211_prepare_vif (and so the relevant `iw phy x interface add y` command) runs, the kernel might still be cleaning up the old interface with the same ifname. It usually takes very few time to do that; possibly a few milliseconds of sleep in the script after detecting this error condition could be enough, but the busybox sh does not support sub-second sleep intervals. When this happens, iw obviously fails to create the new interface; and the following message is printed in the system log, followed by subsequent failure messages from hostapd in case this would have been an AP interface. Tue Mar 14 04:21:57 2017 daemon.notice netifd: radio1 (2767): command failed: Too many open files in system (-23) This was a long-standing issue existing since at least OpenWrt Backfire, and today I finally managed to debug and (hopefully) solve it. It was happening very few times on most devices; but it was happening a lot more frequently on fast platforms with multiple radios, such as the powerpc-based dual-ath9k-radio tl-wdr4900-v1.

* mac80211, hostapd: always explicitly set beacon intervalMatthias Schiffer2017-05-272-5/+7
| | | | | | | | | | | | | | | | One of the latest mac80211 updates added sanity checks, requiring the beacon intervals of all VIFs of the same radio to match. This often broke AP+11s setups, as these modes use different default intervals, at least in some configurations (observed on ath9k). Instead of relying on driver or hostapd defaults, change the scripts to always explicitly set the beacon interval, defaulting to 100. This also applies the beacon interval to 11s interfaces, which had been forgotten before. VIF-specific beacon_int setting is removed from hostapd.sh. Fixes FS#619.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So here is another round of improvements for MT7620 WiFi. This commit fixes a few significant issues related to TX_PWR_CFG_x and TX_ALC and also makes the code more readable by adding register descriptions for things added for MT7620 and use the usual bit-field access macros and the now defined macros instead of plain bit-ops and magic numbers. Properly describe EEPROM_TARGET_POWER at word 0x68 (== byte 0xD0) and thereby fix internal TXALC which would otherwise just read out-of-bounds of the EEPROM map. Split-out tx-power/ALC related stuff into an additional function. Fix VCO calibration, it was carried out properly in the channel switching but incomplete in the actual VCO calibration function. Also there is no need to trigger VCO calibration in channel switching, the VCO calibration function is already being called at this point. Remove it from channel switching function to avoid redundant code. The TX power calibration differs significantly from all other Mediatek/Ralink chips: They finally allow 0.5dB steps stored as 8-bit values for (almost) each bitrate -- and promptly ran out of space and for some reason didn't want to change the EEPROM layout. The hence opted for a scheme of sharing values for some adjecent bitrates and a highly over-complicated (or obfuscated?) way to populate the TX_PWR_CFG_x registers with the values stored in the EEPROM. The code here now looks much less complicated than what you see in the vendor's driver, however, it does the exact same thing: bGpwrdeltaMinus is a constant and always TRUE, hence half of the code was dead. Gpwrdelta is always 0 (rather than using the value read from the EEPROM). What remains is some very grotesque effort to avoid 0x20, probably some hardware bug related to some misunderstanding of what a singed 8-bit value is (imagine: if it was a signed 6-bit value then someone could believe that 0x20 == 0x0). And then they didn't clean it up once they later on anandonned that whole story of having a constant offset for 40 MHz channels and just set the offset to be constant 0 -- there is no effort for avoiding 0x20 for the 20 MHz values stored in the EEPROM, hence that's probably just a forbidden value in the EEPROM specs and won't appear anyway... Anyway, the whole thing felt like solving some college math test where in the end everything cancels out and the result equals 0 ;) To make sure that channel bandwidth power compensation really doesn't need to be taken care of, output a warning when the corresponding value stored in the EEPROM is non-zero. Also there is no apparent reason to refrain from initializing RFCSR register 13, it doesn't fail what-so-ever. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
