When starting a domU of type "pvh" I do not get any SDL output. In the config file I set type = "pvh" vfb = ['vnc=0,sdl=1,keymap=de'] Is this something that should normally work? The following things I already tried and checked: 1) I switched to vnc vfb = ['vnc=1,vnclisten=0.0.0.0,sdl=0,keymap=de'] This works without problems! Within a VNC client I get a virtual terminal with login prompt and can start the xorg server. 2) I started a domU of type "pvhvm" type = "hvm" xen_platform_pci = 1 vga = "stdvga" vnc = 0 sdl = 1 This works without problems! An SDL window opens, which I use for a complete KDE Plasma desktop. 3) An old Installation on the same Hardware, with xen 4.12.1 on arch linux and SDL version 1.2 This works without problems! An SDL window opens for domus of any kind, "pvh" and "pvhvm". THX for any help!

I've noticed that a decompressed guest kernel refuses to boot under PVH with the following error: Loading Linux 5.4.0-52-generic ... error: invalid magic number. That same kernel boots with PV. If I use the LZ4-compressed version of that kernel as supplied by the distribution (Ubuntu 20.04), it works PVH. I therefore can only conclude that PVH grub doesn't like kernels with no compression. Is that expected? I suppose it is possible that the method I use to decompress the kernel could be wrong, though as I say, it does work with PV grub. I basically use the extract-vmlinux script from the upstream kernel source¹. When decompressed: $ sudo file /boot/vmlinuz-5.4.0-52-generic /boot/vmlinuz-5.4.0-52-generic: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, BuildID[sha1]=d435b2b7b13b7e1904dddeee22bff30225d2bd04, stripped $ ls -lah /boot/vmlinuz-5.4.0-52-generic -rw------- 1 root root 43M Nov 1 20:00 /boot/vmlinuz-5.4.0-52-generic When leaving it LZ4 compressed as it comes from the distributor: $ sudo file /boot/vmlinuz-5.4.0-52-generic /boot/vmlinuz-5.4.0-52-generic: Linux kernel x86 boot executable bzImage, version 5.4.0-52-generic (buildd@lgw01-amd64-060) #57-Ubuntu SMP Thu Oct 15 10:57:00 UTC 2020, RO-rootFS, swap_dev 0xB, Normal VGA $ ls -lah /boot/vmlinuz-5.4.0-52-generic -rw------- 1 root root 12M Oct 15 11:33 /boot/vmlinuz-5.4.0-52-generic The reason why I am decompressing these guest kernels is because PV grub does not understand LZ4 compression and as I currently do boot guests this way, they would be unbootable otherwise. For new installs I can skip installing my hack that decompresses the kernel image, but if PVH grub won't support uncompressed kernel images then this is inconvenient for the installed base who will need to make extra changes. Is not supporting decompressed kernel images a bug in PVH grub?

I therefore can only > conclude that PVH grub doesn't like kernels with no compression. Is > that expected? Can you boot the decompressed kernel on bare metal or in an HVM domain using grub? I'm asking because PVH grub is using the standard i386 kernel loading functions, so I wouldn't expect any differences here compared to bare metal. It might still be that PVH grub is missing some code due to wrong configure parameters, of course.

The decompressed kernel doesn't boot bare metal either (same message). The decompressed kernel is generated like this: # extract-vmlinux /boot/vmlinuz-5.4.0-52-generic > /boot/vmlinuz-5.4.0-52-generic-decompressed The decompressed kernel does boot when presented to the hypervisor directly, i.e. no grub, directly listed in guest config file. I don't have an HVM test setup right now so am unable to test that, but I suppose we can assume it will fail as the problem is in the standard grub loading functions. So, is this a bug? Grub should be able to boot uncompressed kernels, shouldn't it?

I actually think now that the output of extract-vmlinux lacks something and I further suspect that if I would use a vmlinux file from within a kernel build tree it would be fine. In which case this is not an issue for grub or xen, and only for those of us employing hacks based around extract-vmlinux. Apologies for the distraction!

No need to apologize. We should really think about adding lz4 decompression support to grub for being able to use lz4 compressed kernels with pvgrub.

No, at least not the one you gave it on x86.

The patches supplied in XSA-286 version 4 were found to have a significant performance impact. An alternative approach was developed and has now been committed to the relevant Xen branches. The alternative approach is simpler and mitigates the performance problems. At the time of writing the patches in XSA-286 v4 are believed to be correct and sound, but if we discover that this is not the case we will not issue a further update. We recommend the use of the patches provided in the Xen git branches, which are the same as those attached in this version of the advisory. ISSUE DESCRIPTION ================= x86 PV guest kernels may use hypercalls with INVLPG-like behavior to invalidate TLB entries even after changes to non-leaf page tables. Such changes to non-leaf page tables will, however, also render stale possible TLB entries created by Xen's internal use of linear page tables to process guest requests like update-va-mapping. Invalidation of these TLB entries has been missing, allowing subsequent guest requests to change address mappings for one process to potentially modify memory meanwhile in use elsewhere. IMPACT ====== Malicious x86 PV guest user mode may be able to escalate their privilege to that of the guest kernel. VULNERABLE SYSTEMS ================== All versions of Xen expose the vulnerability. The vulnerability is exposed to x86 PV guests only. x86 HVM/PVH guests as well as ARM ones are not vulnerable. MITIGATION ========== There is no known mitigation. CREDITS ======= This issue was discovered by Jann Horn of Google Project Zero.

Cortex-A72 (NXP LS1028A) and running int= o some problems here. While some of them I could solve on my own, the following error is hard for= me to understand and solve. I would be grateful for some hints e.g. about some specific nodes in the de= vice tree that I might need to take care of.

Compilation was successful with no errors. I'm using a hvm-domU as driver domain (called: net-11) for my network-interfaces (wlan0 03:00.0/enp4s0 04:00.0). If i start the domU(net-11) without any pci device it is fully working (except internet access ofc). But the machine doesn't start if i try to atach a pci device either via config-file. also "xl pci-attach" doesn't work ("already assigned"). Can't connect to the vm via vnc.

Hello.

I'm trying to boot Windows 10 x64 bit guest os installed physically on the=20 disk GPT + EFI SDC,on the sdc2 partition from the host os Ubuntu 20.10=20 where I have installed XEN 4.14. On sdc3 of the guest disk there is=20 another installation of Ubuntu. Give a look below :

the problem that I have is that the ovmf.bin file has been generated when I have started the installation / configuration of XEN 4.14 doing :


<= code class=3D"gmail-_34q3PgLsx9zIU5BiSOjFoM">./conf= igure --enable-ovmf


,but for some reason it seems to be damaged and it is not able to shows=20 correctly what's happening inside the vncviewer window,where windows 10= =20 is loading itself. To fix it,I have also tried to rename the file=20 OVMF_VARS.fd to ovmf.bin and I tried to boot windows 10 with that file :


cp /etc/xen/xen-4.14.0/tools/firmware/ovmf-dir-remote/Build/OvmfX64/RELEA= SE_GCC5/FV/OVMF_VARS.fd /etc/xen/Nazim/4.14/ovmf.bin

putting inside the xen cfg file :


<= /p>

bios=3D'ovmf'

bios_overr= ide =3D '/etc/xen/Nazim/4.14/ovmf.bin'


but even this experiment didn't work :


=
3D"r/xen
=
3D"r/xen<= /a>

anyway,the passthrough works (my monitor is turned on). w= hat u suggest to me to do ?

Mario.

Do you have a grub install for the Xen domU in the ESP/EFI part? If you don't, you might be able to enter the menu if tiano-core ever launches.

Message-ID: X-Sender: bill@ca-zephyr.org User-Agent: Roundcube Webmail/1.3.15 I am working on moving our Xen servers to Ubuntu 20.04 and am having problems creating domu's using xen-tools. The xen-create-image execution completes but the resulting domu does not boot. Here is the command line I am using for the build. /usr/bin/xen-create-image --hostname=zoot.ca-zephyr.org \ --memory=4Gb --genpass=1 --size=40Gb --dhcp --vcpus=2 \ --pygrub --swap=2Gb --role=udev,/etc/xen-tools/role.d/cz-bionic \ --dist=bionic --arch=amd64 The resulting container does not have grub installed. When I look at ? I see that the attempt is to install grub. But the "grub" package is not available on 20.04. At this point I started just hacking. I changed to using pvgrub by commenting out the 'bootloader' parameter in the domu configuration file and added the line 'which resulted in booting the container to the "grub>" prompt. But with the domu's /boot empty this of course did not lead anywhere. I then just hacked on /usr/share/xen-tools/focal.d/82-install-grub-legacy and changed the install line to 'grub2'. With that the domu boot directory was not empty, but the boot still stopped at the 'grub>' prompt. So, now that I have done this the wrong way I would be very grateful is someone could point me in the correct direction.

I haven't looked at pygrub in quite a few years, having moved to pvgrub, but please note that Ubuntu 20.04 uses LZ4-compressed kernels which pvgrub doesn't currently support. If wanting to do pvgrub with Ubuntu 20.04 you'll need to decompress the kernels with something like this: https://github.com/bitfolk/decompress-lz4-kernels Or switch to PVH, which has no such problems.

I have tried a development build after this was fixed, and they work, but I'd really like a properly signed set of drivers. Any idea when to expect the next signed release ?

I could of course downgrade the hypervisor and reboot, tweak my windows hvm config to boot under older xen and with the virtual cd as xvd? and the rest as hd?, boot the vm, reboot the vm with all drives ax xvd?, reinistall xen-4.14, reboot the server and be good to go.

charset="utf-8" Content-Disposition: inline Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Xen Security Advisory XSA-355 version 2 stack corruption from XSA-346 change UPDATES IN VERSION 2 ==================== Added metadata file. Public release. ISSUE DESCRIPTION ================= One of the two changes for XSA-346 introduced an on-stack array. The check for guarding against overrunning this array was off by one, allowing for corruption of the first stack slot immediately following this array. IMPACT ====== A malicious or buggy HVM or PVH guest can cause Xen to crash, resulting in a Denial of Service (DoS) to the entire host. Privilege escalation as well as information leaks cannot be excluded. VULNERABLE SYSTEMS ================== All Xen versions which have the patches for XSA-346 applied are vulnerable. Only x86 HVM and PVH guests can leverage the vulnerability. Arm guests and x86 PV guests cannot leverage the vulnerability. Only x86 HVM and PVH guests which have physical devices passed through to them can leverage the vulnerability. MITIGATION ========== Not passing through physical devices to untrusted guests will avoid the vulnerability. CREDITS ======= This issue was discovered by Jan Beulich of SUSE. RESOLUTION ========== Applying the attached patch resolves this issue. Note that patches for released versions are generally prepared to apply to the stable branches, and may not apply cleanly to the most recent release tarball. Downstreams are encouraged to update to the tip of the stable branch before applying these patches. xsa355.patch xen-unstable - Xen 4.10.x $ sha256sum xsa355* a93bfc376897e7cffd095d395f1a66476adb9503d7d80a59b7861e64c2675323 xsa355.meta dae633c11cf2eff3e304737265e18ab09213e8e4640458080a944ae7a40819a4 xsa355.patch $ NOTE CONCERNING SHORT EMBARGO ============================= This issue is likely to be re-discovered as the changes for XSA-346 are deployed more widely, since the issue is also triggerable without any malice or bugginess. DEPLOYMENT DURING EMBARGO ========================= Deployment of the patches and/or mitigations described above (or others which are substantially similar) is permitted during the embargo, even on public-facing systems with untrusted guest users and administrators. But: Distribution of updated software is prohibited (except to other members of the predisclosure list). Predisclosure list members who wish to deploy significantly different patches and/or mitigations, please contact the Xen Project Security Team.

ISSUE DESCRIPTION ================= Researchers have demonstrated using software power/energy monitoring interfaces to create covert channels, and infer the operations/data used by other contexts within the system. Access to these interfaces should be restricted to privileged software, but it was found that Xen doesn't restrict access suitably, and the interfaces are accessible to all guests. For more information, see: https://platypusattack.com https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00389.html IMPACT ====== An unprivileged guest administrator can sample platform power/energy data. This may be used to infer the operations/data used by other contexts within the system. The research demonstrates using this sidechannel to leak the AES keys used elsewhere in the system. VULNERABLE SYSTEMS ================== Power/energy monitoring interfaces are platform and architecture specific. Consult your hardware vendor to ascertain what power feedback interfaces are available. For ARM systems, all versions of Xen are vulnerable. The fix restricts access to the AMU (Activity Monitors Unit) interface, introduced in Armv8.4. For x86 systems, Xen 4.14 and earlier are vulnerable - master is not vulnerable, as these issues have been addressed in a more general fashion. The x86 fixes restrict access to: * Intel RAPL interface, introduced in SandyBridge CPUs. * Intel platform energy interface. * Intel perf_ctl interface, introduced in Pentium 4 CPUs and also implemented by other vendors. * AMD RAPL interface, introduced in Ryzen/EPYC CPUs. * AMD compute unit energy interface, present in Fam15/16 CPUs. MITIGATION ========== There are no mitigations available. RESOLUTION ========== Applying the appropriate attached patch resolves this issue. Note that patches for released versions are generally prepared to apply to the stable branches, and may not apply cleanly to the most recent release tarball. Downstreams are encouraged to update to the tip of the stable branch before applying these patches. xsa351-arm.patch Xen unstable - 4.10.x [ARM] xsa351-x86-4.14-?.patch Xen 4.14.x [x86]
