d67371fd | 2020-07-14 15:42:19 | Implement pci_intr_establish_cpu() on arm64 and armv7. The function pointer in the chipset tag for establishing interrupts now takes a struct cpu_info *. The normal pci_intr_establish() macro passes NULL as ci, which indicates that the primary CPU is to be used. The PCI controller drivers can then simply pass the ci on to our arm64/armv7 interrupt establish "framework". Prompted by dlg@ ok kettenis@ | |
|
789e88a4 | 2020-07-14 15:34:14 | Extend the interrupt API on arm64 and armv7 to be able to pass around a struct cpu_info *. From a driver point of view the fdt_intr_establish_* API now also exist same functions with a *_cpu suffix. Internally the "old" functions now call their *_cpu counterparts, passing NULL as ci. NULL will be interpreted as primary CPU in the interrupt controller code. The internal framework for interrupt controllers has been changed so that the establish methods provided by an interrupt controller function always takes a struct cpu_info *. Some drivers, like imxgpio(4) and rkgpio(4), only have a single interrupt line for multiple pins. On those we simply disallow trying to establish an interrupt on a non-primary CPU, returning NULL. Since we do not have MP yet on armv7, all armv7 interrupt controllers do return NULL if an attempt is made to establish an interrupt on a different CPU. That said, so far there's no way this can happen. If we ever gain MP support, this is a reminder that the interrupt controller drivers have to be adjusted. Prompted by dlg@ ok kettenis@ | |

8bdc3b62 | 2020-07-14 14:33:03 | A pty write containing VDISCARD, VREPRINT, or various retyping cases of VERASE would perform (sometimes irrelevant) compute in the kernel which can be heavy (especially with our insufficient tty subsystem locking). Use tsleep_nsec for 1 tick in such circumstances to yield cpu, and also bring interruptability to ptcwrite() https://syzkaller.appspot.com/bug?extid=462539bc18fef8fc26cc ok kettenis millert, discussions with greg and anton | |

1a9b7fd9 | 2020-07-14 06:02:50 | Do not convert the NOCACHE buffers that come from a vnd strategy routine into more delayed writes if the vnd is mounted from a file on an MNT_ASYNC filesystem. This prevents a situaiton where the cleaner can not clean delayed writes out without making more delayed writes, and we end up waiting for the syncer to spit things occasionaly when it runs. noticed and reported by sven falempin <sven.falempin@gmail.com> on tech, who validated this fixes his issue. ok krw@ | |

07af7ebb | 2020-07-14 04:10:18 | Set up a second level flow table for RSS and switch the root flow table entries to forwarding packets to it. The RSS flow table contains flow table entries that match specific types of traffic and send them to TIRs set up to hash on the appropriate fields, then deliver packets through an RQT to all our rx queues. We still only have one queue, but now all we need to do is plug in an intrmap to add more. ok dlg@ | |

|
50b95bf0 | 2020-07-13 16:18:52 | Increase iwx(4) command queue size to the size expected by hardware. The iwx(4) command queue has 256 entries in hardware. The Linux driver contains an abstraction layer which allows it to allocate just 32 command queue entries in software. Because I misunderstood how this works iwx(4) ended up with 32 command queue entries, but without a shim which presents these 32 entries as 256 entries to hardware. Our command queue size was later bumped to 64 to make fatal firmware errors during initialization disappear. The problem was still not fully understood at that time. I didn't realize that firmware errors coincided with the command queue index wrapping around. Hardware expects the queue to wrap at 256 entries so fix this problem for good in a simple way: Allocate 256 entries for the command queue, just like iwm(4) does. This will allow us to enable background scanning on iwx(4), which so far triggered firmware errors due to additional scan commands causing the command queue index to wrap at 64. | |

d114bbad | 2020-07-13 14:25:41 | Where we have a pointer (sc) to the relevant adapter_softc, use &sc->sc_dev to get a device pointer rather than using the void * whence we obtained 'sc'. | |
|
d4769f94 | 2020-07-13 13:43:31 | Remove some pointless casting of void * when assigning one (scsi_link.adapter_softc) to a pointer of a particular softc type. | |
|
48439b74 | 2020-07-13 10:40:03 | More preparations for adding RSS. Adjust several functions to allow for the creation of more flow tables and TIRs, and more types of flow entries and TIRs, consolidate flow group details into a single struct, and improve the way doorbells in host memory are laid out. The doorbell memory area is divided into halves for CQs and SQ/RQs, with the doorbells for each CQ and SQ/RQ pair kept 64 bytes apart. This arrangement will allow for up to 32 queues, which is plenty for now. ok dlg@ | |

9a82318d | 2020-07-13 10:35:55 | add kstat support for reading hardware counters. this replaces the existing counters implementation, which just collected the stats in the softc, but didn't really provide a way for a person to read them. em counters get cleared on read. a lot of them are 32bit, so to avoid overflow the counters are polled and the newly accumulated values are added to some 64 bit counters in software. tested by hrvoje popovski and SAITOH Masanobu ok mpi@ i missed these files when i committed src/sys/dev/pci/if_em.c r1.356. thanks to jsg for pointing this out. | |

86e3bb8a | 2020-07-13 08:31:32 | When athn(4) is deciding how to decrypt an incoming frame, look into the ieee80211_node data structure to find the WPA group cipher which was negotiated with the peer, rather than checking the wireless interface's configuration data. Found while investigating a problem where WPA2+TKIP wasn't working with athn. Problem reported by Tim Chase. | |
 |
e3884aa0 | 2020-07-13 08:29:34 | Unbreak wg(4). Previous may have fixed the build without pf(4), but broke wireguard in normal kernels: the condition NPF > 0 is false if pf.h is not in scope. | |
|
f82e3dee | 2020-07-13 08:26:26 | When a wifi interface acts as a client and the WPA handshake is done, update the WPA group cipher value in interface configuration data. Code relying in this value will otherwise get the group cipher wrong. One obvious example is ifconfig which now displays the negotiated group cipher rather than always displaying the default value 'ccmp'. Fixes a regression where athn(4) no longer worked against WPA2 APs which use TKIP as a group cipher for compatibility with WPA1. Problem reported by Tim Chase. ok kettenis@ | |

578cbe2e | 2020-07-13 03:28:20 | let's be explicit about only supporting Ethernet ports as members. the packet parsing code expects Ethernet packets, so only allow Ethernet interfaces to be added. ok sthen@ | |
|
c8af3b80 | 2020-07-13 03:21:33 | when adding a non-existent interface as a port, don't try create missing ones. this was annoying if i made a typo like "ifconfig bridge0 add gre0" instead of "ifconfig bridge0 add egre0" because it would create gre0 and then get upset cos it's not an Ethernet interface. also, it left gre0 lying around. this used to be useful when configuring a bridge on boot because interfaces used to be created when they were configured, and bridges could be configured before some virtual interfaces. however, netstart now creates all necessary interfaces before configuring any of them, so bridge being helpful isn't necessary anymore. ok kn@ | |

69657d9a | 2020-07-09 02:17:07 | adjfreq(2): limit adjustment to [-500000, +500000] ppm When we recompute the scaling factor during tc_windup() there is an opportunity for arithmetic overflow if the active timecounter's adjfreq(2) adjustment is too large. If we limit the adjustment to [-500000, +500000] ppm the statement in question cannot overflow. In particular, we are concerned with the following bit of code: scale = (u_int64_t)1 << 63; scale += \ ((th->th_adjustment + th->th_counter->tc_freq_adj) / 1024) * 2199; scale /= th->th_counter->tc_frequency; th->th_scale = scale * 2; where scale is an int64_t. Overflow when we do: scale += (...) / 1024 * 2199; as th->th_counter->tc_freq_adj is currently unbounded. th->th_adjustment is limited to [-5000ppm, 5000ppm]. To see that overflow is prevented with the new bounds, consider the new edge case where th->th_counter->tc_freq_adj is 500000ppm and th->th_adjustment is 5000ppm. Both are of type int64_t. We have: int64_t th_adjustment = (5000 * 1000) << 32; /* 21474836480000000 */ int64_t tc_freq_adj = 500000000LL << 32; /* 2147483648000000000 */ scale = (u_int64_t)1 << 63; /* 9223372036854775808 */ scale += (th_adjustment + tc_freq_adj) / 1024 * 2199; /* scale += 2168958484480000000 / 1024 * 2199; */ /* scale += 4657753620480000000; */ 9223372036854775808 + 4657753620480000000 = 13881125657334775808, which less than 18446744073709551616, so we don't have overflow. On the opposite end, if th->th_counter->tc_freq_adj is -500000ppm and th->th_adjustment is -5000ppm we would have -4657753620480000000. 9223372036854775808 - 4657753620480000000 = 4565618416374775808. Again, no overflow. 500000ppm and -500000ppm are extreme adjustments. otto@ says ntpd(8) would never arrive at them naturally, so we are not at risk of breaking a working setup by imposing these restrictions. Documentation input from kettenis@. No complaints from otto@. | |

deaec079 | 2020-07-08 15:53:59 | Make membar_consumer() a plain compiler barrier in kernel on octeon. The processor does not perform speculative reads and only one of its execution pipes should issue memory accesses. As a result, loads should happen in the correct order without barrier instructions. Tested on CN5020, CN6120, CN7130 and CN7360. This diff has been in use on the octeon-based mips64 bulk build cluster for several months. Also tested in snaps for a while. | |
