2019-11-20net: ethernet: ti: cpsw: resolve build deps of cpsw driversGrygorii Strashko3-8/+17
A following patches introduce new CPSW switchdev driver which uses common code with legacy CPSW driver. This will introduce build dependency between CPSW switchdev and CPSW legacy drivers related to for_each_slave() and cpsw_slave_index() - they can be compiled both, but only one of them will be not functional depending in Kconfig settings due to duffrences in Slave Ports indexes calculation. To fix this make for_each_slave() local (it's used now only by legacy CPSW driver) and convert cpsw_slave_index() to be a function pointer which is assigned in probe. Driver to probe is defined by DT. Signed-off-by: Grygorii Strashko <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2019-11-20arm64: uaccess: Remove uaccess_*_not_uao asm macrosPavel Tatashin7-35/+27
It is safer and simpler to drop the uaccess assembly macros in favour of inline C functions. Although this bloats the Image size slightly, it aligns our user copy routines with '{get,put}_user()' and generally makes the code a lot easier to reason about.

2019-11-20arm64: uaccess: Ensure PAN is re-enabled after unhandled uaccess faultPavel Tatashin4-0/+4
A number of our uaccess routines ('__arch_clear_user()' and '__arch_copy_{in,from,to}_user()') fail to re-enable PAN if they encounter an unhandled fault whilst accessing userspace. For CPUs implementing both hardware PAN and UAO, this bug has no effect when both extensions are in use by the kernel. For CPUs implementing hardware PAN but not UAO, this means that a kernel using hardware PAN may execute portions of code with PAN inadvertently disabled, opening us up to potential security vulnerabilities that rely on userspace access from within the kernel which would usually be prevented by this mechanism. In other words, parts of the kernel run the same way as they would on a CPU without PAN implemented/emulated at all. For CPUs not implementing hardware PAN and instead relying on software emulation via 'CONFIG_ARM64_SW_TTBR0_PAN=y', the impact is unfortunately much worse. Calling 'schedule()' with software PAN disabled means that the next task will execute in the kernel using the page-table and ASID of the previous process even after 'switch_mm()', since the actual hardware switch is deferred until return to userspace. At this point, or if there is a intermediate call to 'uaccess_enable()', the page-table and ASID of the new process are installed. Sadly, due to the changes introduced by KPTI, this is not an atomic operation and there is a very small window (two instructions) where the CPU is configured with the page-table of the old task and the ASID of the new task; a speculative access in this state is disastrous because it would corrupt the TLB entries for the new task with mappings from the previous address space. As Pavel explains: | I was able to reproduce memory corruption problem on Broadcom's SoC | ARMv8-A like this: | | Enable software perf-events with PERF_SAMPLE_CALLCHAIN so userland's | stack is accessed and copied. | | The test program performed the following on every CPU and forking | many processes: | | unsigned long *map = mmap(NULL, PAGE_SIZE, PROT_READ|PROT_WRITE, | MAP_SHARED | MAP_ANONYMOUS, -1, 0); | map[0] = getpid(); | sched_yield(); | if (map[0] != getpid()) { | fprintf(stderr, "Corruption detected!"); | } | munmap(map, PAGE_SIZE); | | From time to time I was getting map[0] to contain pid for a | different process. Ensure that PAN is re-enabled when returning after an unhandled user fault from our uaccess routines.

2019-11-20lwtunnel: add support for multiple geneve optsXin Long1-36/+75
geneve RFC (draft-ietf-nvo3-geneve-14) allows a geneve packet to carry multiple geneve opts, so it's necessary for lwtunnel to support adding multiple geneve opts in one lwtunnel route. But vxlan and erspan opts are still only allowed to add one option. With this patch, iproute2 could make it like: # ip r a 1.1.1.0/24 encap ip id 1 geneve_opts 0:0:12121212,1:2:12121212 \ dst 10.1.0.2 dev geneve1 # ip r a 1.1.1.0/24 encap ip id 1 vxlan_opts 456 \ dst 10.1.0.2 dev erspan1 # ip r a 1.1.1.0/24 encap ip id 1 erspan_opts 1:123:0:0 \ dst 10.1.0.2 dev erspan1 Which are pretty much like cls_flower and act_tunnel_key.

This reverts commit 34b0e9b767bfa09ae233ca0d6ceb299bf2e24600. Since commit 7bd0650be63c ("mt76: dma: fix buffer unmap with non-linear skbs") is no longer necessary to disable HW encryption for MT7630E. Disabling HW encryption helped previously because somehow fragmented skb's are not created if mac80211 encrypt frames, so buffer unmap bug of non-linear skbs was not triggered. Now since this bug is properly fixed by commit 7bd0650be63c ("mt76: dma: fix buffer unmap with non-linear skbs") , we can enable HW encryption back.

2019-11-20mt76: mt7615: track tx/rx airtime for airtime fairnessLorenzo Bianconi6-3/+137
Poll per-station hardware counters available in WTBL after tx/rx status events in order to report tx/rx airtime to mac80211 layer Co-developed-by: Felix Fietkau <[email protected]> Signed-off-by: Lorenzo Bianconi <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
2019-11-20mt76: mt7615: introduce mt7615_mac_wtbl_update routineLorenzo Bianconi2-5/+12
Introduce mt7615_mac_wtbl_update utility routine in order to update WTBL update register Signed-off-by: Lorenzo Bianconi <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
2019-11-20mt76: mt7615: fix survey channel busy timeFelix Fietkau2-4/+8
Like on mt7603, MIB status register 16 tracks CCA time, but does not include tx time. Switch to status register 9 to includ NAV and tx time as well. Signed-off-by: Felix Fietkau <[email protected]>
2019-11-20mt76: mt7615: report tx_time, bss_rx and busy time to mac80211Lorenzo Bianconi7-4/+45
Report tx time/rx time and obss time from hw mib counters to fill survey info requested by mac80211 Co-developed-by: Felix Fietkau <[email protected]> Signed-off-by: Lorenzo Bianconi <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
2019-11-20mt76: mt76x02: track approximate tx airtime for airtime fairness and surveyFelix Fietkau12-9/+116
Estimate by calculating duration for EWMA packet size + estimated A-MPDU length on tx status events Signed-off-by: Felix Fietkau <[email protected]>
2019-11-20mt76: mt76x02: move MT_CH_TIME_CFG init to mt76x02_mac_cc_resetFelix Fietkau5-32/+9
Reduces code duplication and adds missing bits for USB variants Signed-off-by: Felix Fietkau <[email protected]>
2019-11-20mt76: unify channel survey update codeFelix Fietkau8-52/+33
Host time is used to calculate the channel active time on mt7603 and mt7615. Use the same on mt76x02 and move the lock to core code to get rid of some duplicated code. Signed-off-by: Felix Fietkau <[email protected]>
2019-11-20mt76: mt7603: switch to a different counter for survey busy timeFelix Fietkau1-1/+1
MT_MIB_STAT_PSCCA only counts rx CCA busy time, which does not include tx time. MT_MIB_STAT_CCA counts full busy time, including Rx, Tx and NAV Signed-off-by: Felix Fietkau <[email protected]>
2019-11-20mt76: mt7603: track tx airtime for airtime fairness and surveyFelix Fietkau7-1/+116
Poll per-station hardware counters after tx status events Signed-off-by: Felix Fietkau <[email protected]>
2019-11-20mt76: track rx airtime for airtime fairness and surveyFelix Fietkau12-37/+434
Report total rx airtime for valid stations as BSS rx time in survey mt7615 is left out for now, it will be supported later by reading hardware counters instead of calculating airtime in software Signed-off-by: Felix Fietkau <[email protected]>
