f2cc1b42 | 2019-11-10 20:51:52 | Consistently use _rcctl enable foo_ in examples, it's simpler and less error prone than manually editing rc.conf.local, and also works to enable ipsec and accounting. tweak from schwarze@ to use the \(dq\(dq syntax for quotes in '.Dl foo_flags="" lines' instead of \&"\&". while at it, fix a reference to a bogus /dev/dhclient.conf file that recently snuck in. ok jmc@ deraadt@ schwarze@ | |

df69c215 | 2019-06-28 13:32:41 | When system calls indicate an error they return -1, not some arbitrary value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future. | |

a50a4aa6 | 2019-05-27 19:21:43 | only reschedule the periodic interrupt after updating register A if something changed in register A. when updating register A we were checking in register B if the PIE bit was set in order to decide if rtc_reschedule_per needed to be called. if that bit was changed then the timer rate would already have been adjusted by rtc_update_regb so the call from rtc_update_rega is not needed. this now matches what qemu and other emulators are doing too. ok mlarkin@ | |

93622bc9 | 2019-01-22 10:12:36 | vmd: reorder PCI device assignment to fix Linux network interface numbering On some recent Linux guests, the virtio network interface is named based on its PCI slot assignment, eg "enp0s3". Prior to this change, vmd assigned disks first, meaning if you used a disk image to install Linux and then removed it after install, the network interface name would change from "enp0s3" to "enp0s2" (for example). This broke any autoconfiguration script config files written during the install and generally led to users just being confused about what was going on. This change reorders the vmd PCI device assignment to put network interfaces before disks, as disk devices don't seem to have the same naming issue. This means the slot for network interfaces won't change. IMPORTANT NOTE - if you have existing Linux guest VMs, you'll need to manually fixup your config files (once). ok ajacoutot, phessler, ccardenas, deraadt@ | |

bbbb23fd | 2019-01-18 01:24:07 | disable vmd/vmctl for i386 Next commit will delete vmm(4) for i386. Reasons to delete i386 vmm: - Been broken for a while, almost no one complained. - Had been falling out of sync from amd64 while it worked. - If your machine has vmx, you most probably can run amd64, so why not run that? ok mlarkin@ deraadt@ | |

fb6f09fa | 2019-01-10 19:21:02 | an alloca() snuck into the tree. We don't use alloca() in our tree unless it is entirely unavoidable (for example libc/*/exec.c), because any erroneous size controlled by an attacker turns into a known-location object placement in a very dangerous region. So use malloc() instead. | |

622c1441 | 2018-12-10 21:30:33 | Implement the fw_cfg interface basics and use it to set the bootorder if a bootdevice was forced. This implements both the pure IO port interface and also the new DMA interface, a few direct commands are implemented which are needed but in general the "file" interface should be used. There is no write support for the guest. Tested against the latest vmm-firmware port. This requires also a -current kernel to pass the IO ports to vmd(8). OK mlarkin@ ccardenas@ | |

|
cc104512 | 2018-12-06 09:20:06 | Make it possible to define the bootdevice in vmd. This information is used currently only when booting a OpenBSD kernel. If VMBOOTDEV_NET is used the internal dhcp server will pass "auto_install" as boot file to the client and the boot loader passes the MAC of the first interface to the kernel to indicate PXE booting. Adding boot order support to SeaBIOS is not yet implemented. Ok ccardenas@ | |
|
95176482 | 2018-12-04 08:15:09 | Introduce IMSG_VMDOP_WAIT_VM_REQUEST a control message that registers a vmctl peerid that should be informed when the VM is stopped (like when the guest does a shutdown). Uses the same logic as using the VMOP_WAIT flag on IMSG_VMDOP_TERMINATE_VM_REQUEST. Ok ccardenas@, reyk@ | |

62df93ee | 2018-11-26 10:39:30 | Move the {qcow2,raw} create functions from vmctl into vmd/vio{qcow2,raw}.c This way they are in the appropriate place and code can be shared with vmd. Ok ori@ mlarkin@ ccardenas@ | |

a1533359 | 2018-11-01 00:18:44 | - odd condition/test in PF lexer (and other lexers too) This commit rectifies earlier change: in the lex... even inside quotes, a \ followed by space or tab should expand to space or tab, and a \ followed by newline should be ignored (as a line continuation). compatible with the needs of hoststated (which has the most strict quoted string requirements), and ifstated (where one commonly does line continuations in strings).

a7eff89f | 2018-10-26 11:24:45 | I broke base images with my previous commit by missing a line. The disk path wasn't updated so vmd tried to open the derived disk image for each base over and over again. OK ori@ mlarkin@ | |
|
ed9943e8 | 2018-10-24 05:19:03 | Fix qcow2 disk images for data sizes greater than 4 gigs. We used to truncate the disk end by anding it with a 32 bit value. The 32 bit value was not sign extended, which causes the disk size to wrap at 4 gigabytes: disk->end = (disk->end + disk->clustersz - 1) & ~(disk->clustersz - 1); This change converts the clustersz to an off_t in order to remove the class of errors by avoiding type conversions entirely. | |
 |
29d9fdba | 2018-10-22 16:45:24 | The recent switch to realpath(3) for the boot string in vmd(8) broke vmd-fail-boot-name-too-long regress. Use a relative existing path for this test. Print the error message in vmd config parser. OK ccardenas@ reyk@ | |
|
4d2a1fb2 | 2018-10-19 10:12:39 | Add support to create and convert disk images from existing images The -i option to vmctl create (eg. vmctl create output.qcow2 -i input.img) lets you create a new image from an input file and convert it if it is a different format. This allows to convert qcow2 images from raw images, raw from qcow2, or even qcow2 from qcow2 and raw from raw to re-optimize the disk. This re-uses Ori's vioqcow2.c from vmd by reaching into it and compiling it in. The API has been adjust to be used from both vmctl and vmd accordingly. OK mlarkin@ | |
|
4a91d1ff | 2018-10-18 08:36:11 | Use realpath(3) on the "boot" config option as well. This fixes code that detects if boot and the first disk are identical. OK mlarkin@ | |
|
75cf143a | 2018-10-15 10:35:41 | Prevent VM reboot loops by rate-limiting the interval a VM can reboot. This looping has been experienced by people who run VMs with a broken kernel or boot loader that trigger a very fast reboot loop (triple fault) of a VM that ends up using a lot of CPU and resources on the host. Some fixes in vmm(4) and vmd(8) helped to avoid such conditions but it can still occur if something is wrong in the guest VM itself. If the VM restarts after less than VM_START_RATE_SEC (6) seconds, we increment the limit counter. After VM_START_RATE_LIMIT (3) of suchs fast reboots the VM is stopped. There are only very few people who intentionally want to reboot-loop a VM very quickly (many times within a second); mostly for fuzzing. They will have to recompile and adjust the stated #defines in the code as we don't have a config option to disable it. OK mlarkin@ | |
|
73613953 | 2018-10-08 16:32:01 | Add support for qcow2 base images (external snapshots). This works is from Ori Bernstein, committing on his behalf: Add support to vmd for external snapshots. That is, snapshots that are derived from a base image. Data lookups start in the derived image, and if the derived image does not contain some data, the search proceeds ot the base image. Multiple derived images may exist off of a single base image. A limitation of this format is that modifying the base image will corrupt the derived image. This change also adds support for creating disk derived disk images to vmctl. To use it: vmctl create derived.qcow2 -s 16G -b base.qcow2 From Ori Bernstein OK mlarkin@ reyk@ | |

32cbe138 | 2018-10-04 16:21:59 | vmd(8): don't forget to set TXRDY in the case when the rate limiter isn't going to be used. Issue caused by yesterday's commit, affected certain guests' consoles after interrupts had been enabled. spotted by bluhm@, thanks. | |

|
43965b22 | 2018-10-03 20:13:33 | vmd(8): avoid a divide by zero when the user specified a low baud rate Low baud rates would result in a 0 "rate limiter pause count" in the serial port output code. This pause counter is used to implement a delay in what otherwise is an instantaneous serial port output path, and is needed by some guest OS kernels. This fix only enables the rate limiter pause if the count is > 0 ("pause after 0 characters" makes no sense anyway). Note that this will result in skipping the limiter on unusually low baud rates, but since nobody is using a low baud rate console in vmd, I don't think this is going to be a problem. ok pd | |

4fe3c8f7 | 2018-10-01 17:34:56 | Fix potential double-free in error path qc2_open() calls qc2_close() on error which already frees diskp. OK ccardenas@ | |
|
e2ceadc1 | 2018-10-01 09:31:15 | Try to derive the qcow2 file format from an image file automatically. This makes the "-d qcow2:" and "format qcow" arguments optional as vmctl and vmd will read the magic bytes at the beginning of a file to guess if it is a raw or a qcow image file. The "vmctl create" command has been changed by removing the -f qcow2 option and replacing it with the same syntax as -d: "vmctl create qcow2:foo.img". In a slightly ununixy but intended way, the create command now also considers the file extension for the format as "vmctl create foo.qcow2" creates a qcow2 disk and not a raw image file.

f224f92a | 2018-09-09 04:09:32 | Add initial qcow2 image support. Users are able to declare disk images as 'raw' or 'qcow2' using either vmctl and vm.conf. The default disk image format is 'raw' if not specified. Examples of using disk format: vmctl start bsd -Lc -r cd64.iso -d qcow2:current.qc2 or vmctl start bsd -Lc -r cd64.iso -d raw:current.raw is equivalent to vmctl start bsd -Lc -r cd64.iso -d current.raw in vm.conf vm "current" { disable memory 2G disk "/home/user/vmm/current.qc2" format "qcow2" interface { switch "external" } } or vm "current" { disable memory 2G disk "/home/user/vmm/current.raw" format "raw" interface { switch "external" } } is equivlanet to vm "current" { disable memory 2G disk "/home/user/vmm/current.raw" interface { switch "external" } } Tested by many.

6429e633 | 2018-07-12 12:04:49 | Allow to use configured/running VMs as templates for other VM instances. This introduces new grammar and the -t optional in vmctl start. (For now, only root can create VM instances; but it is planned to allow users to create their own VMs based on permissions and quota.) OK ccardenas@ mlarkin@ jmc@ | |

02ee787f | 2018-07-12 10:15:44 | vmm(8)/vmm(4): send a copy of the guest register state to vmd on exit, avoiding multiple readregs ioctls back to vmm in case register content is needed subsequently. ok phessler | |

f1a97e0a | 2018-07-11 16:37:31 | style - indent each case statement in a switch. | |
|
3be9785f | 2018-07-11 13:19:47 | Add -w option to vmctl stop to wait for completion of VM termination. Use it in /etc/rc.d/vmd accordingly. OK sthen@ | |

05ccfefc | 2018-07-11 10:31:45 | Rename function to vmd_check_vmh | |
|
f6e5c9eb | 2018-07-11 09:35:44 | Add -f option to vmctl stop to forcefully kill a VM. This also fixes a bug in vmm_sighdlr where it might have missed forwarding the TERMINATE_EVENT to the vmd parent after a VM child died, leading to an abandoned VM in the vmd parent process.

a062aa9d | 2018-07-11 07:39:22 | Do for most running out of memory err() what was done for most running out of memory log_warn(). i.e. ("%s", __func__) instead of manual function names and redundant verbiage about which wrapper detected the out of memory condition. ok henning@ | |
|
e1d2f2de | 2018-07-10 21:12:20 | style (single-line ifs don't need braces) | |
|
a014dd99 | 2018-07-10 20:52:51 | Return the VM pid to the vmd parent. This pid field already existed in the result but wasn't filled in by the vmm process. No functional change. | |
|
426e2d59 | 2018-07-10 20:46:50 | Remove a debug message | |
|
1f5e00e0 | 2018-07-10 20:43:15 | vmd already had DEBUG/DPRINTF, there is no need for VMD_DEBUG/dprintf Replace all occurences of dprintf with DPRINTF (defined in proc.h). | |
|
ddadf993 | 2018-07-10 16:15:51 | Tweak debug log messages - Turn tracing messages into DPRINTF (only compiled with DEBUG). - Pass __func__ to vm_stop and vm_remove: this way we can track who called the function in the async context. It replaces the manual log_debug in front of each vm_stop/vm_remove. This debug logging trick can be removed in the future once we are more confident about it. OK ccardenas@ mlarkin@ |
