amd64 pmap: Zero out the EPTP on pmap_create Non-EPT pmaps were picking up old EPTPs from previous owners. This doesn't cause any problems but makes debugging harder. ok dv@ |

vmm(4): reference count vm's and vcpu's Unlocking most of vmm last year at k2k21 exposed bugs related to lifetime management of vm and vcpu objects. Add reference counts to make sure we don't attempt to teardown vcpu or vm related objects while a thread is holding a reference. This also reduces abuse of rwlocks originally intended to protect the linked lists cleaning things up quite a bit. While here, also document assumptions on how struct members are protected for the next brave soul wander in. ok mlarkin@ |

amd64/pmap: Change the wording of a panic string Change a panic string to make the text locatable in the code since there is another panic with the same text. Helps debugging when the line number information isn't available. no functional change. ok dv |

Remove an incorrect KASSERT() introduced in previous. If uvm_pagermapin() fails that doesn't mean the emergency pages aren't in use. In OOM situation, a single segment can still be held by an asynchronous write so the second call to uvm_pagermapin() can fail. |

Allow sysctl mib CTL_NET.PF_INET6 with a length of 3 in PLEDGE_VMINFO. This will be used for sysconf(3) and getconf(1) to handle _POSIX_IPV6 without opening a socket. OK sthen@ deraadt@ |

As we now have two bios_consdev_t structures, make use of the old one until the bootstrap populates the new structure. Found the hard way by Hrvoje Popovski. ok kettenis@ |

Fix bwfm(4) crash during detach on USB. The net80211 stack detach routine can trigger more tasks to be scheduled, e.g. to delete WPA keys. So let's not free the driver's taskq before net80211 has been detached. fixed with and ok by mpi@ Crash reported by mlarkin@ who yanked the USB cable to test our fix. |

Reduce allocations and possible failures in uvm_pagermapin/out(). . If a direct map exists use it to map single-page allocations . Use pmap_kenter_pa() instead of pmap_enter() in all other cases. This speeds up file-based mmap up to 75% when I/O are performed and it also reduces possible allocations failtures in the page daemon making it more stable in OOM situations. ok kettenis@, beck@ |
