- This minor patch implements the missing stub function security_label_to_details in the dummy module. This stub function is necessary to create domains with network interfaces for modules that do not implement the security_label_to_details function.

While compiling XEN with XSM_ENABLE=y and FLASK_ENABLE=y, I received the following error. gcc -O1 -fno-omit-frame-pointer -m64 -g -fno-strict-aliasing -std=gnu99 -Wall -Wstrict-prototypes -Wno-unused-value -Wdeclaration-after-statement -Wno-unused-but-set-variable -fno-builtin -fno-common -Wredundant-decls -iwithprefix include -Werror -Wno-pointer-arith -pipe

This patch set adds XSM security labels to useful debugging output locations, and fixes some assumptions that all interrupts behaved like GSI interrupts (which had useful non-dynamic IDs). It also cleans up the policy build process and adds an example of how to use the user field in the security context. Debug output: [PATCH 01/10] xsm: Add security labels to event-channel dump [PATCH 02/10] xsm:

Hi all, i want to know about the following things: 1.unloading XSM policy. -xl loadpolicy xenpolicy.24 to load the policy. For unloading is there any command is available.? 2. i want to know any analysis tool is available for XSM policy. 3. Apart from wiki.org/XSM any other tutorial is available for developing own XSM policy.? Thanks and regards, cooldharma06.

Hi all. We developped a pv-scsi driver that we refered Fujita-san''s scsi-driver and blkback. (see, http://www.xensource.com/files/xensummit_4/Xen_Summit_8_Matsumoto.pdf) The pv-scsi driver''s feature is as follow: * Guest has dedicated SCSI-HBAs of Dom0. * Guest can send scsi_cdb to the HBAs. * Guest recognises the HBAs from hostno of xenstore. Currentlly, We are

hi all, i am new to the libvirt. Via libvirt i am converting my xen.com.sfg. In xen i added xsm label as, seclabel:system_u:domU_t. but after creating vm using xen or by convertdom-to-xml also does not contain any label or text with xen-4.2.1. in the documentation also you mentioned selinux label (sVirt) only. Can u clear me the following things: 1. How to use XSM label in libvirt.? 2. What

Thanks, as per my knowledge, after downloading the source code, and making changes and then making sure it works properly , recompiling it and then patch it and finally submit a pull request. But what all changes should I/can I make? Please provide me some insight into this. Thanks&Regards, Hemant Kumar Singh On Apr 10 2019, at 10:56 am, Gaurav Arora <gauravarora.daiict at gmail.com>

With the lake of iommu, dom0 must have a 1:1 memory mapping for all these guest physical address. When the ballon decides to give back a page to the kernel, this page must have the same address as previously. Otherwise, we will loose the 1:1 mapping and will break DMA-capable device.

Hi , When cw is used, dom0 reboots. Though I set quest memory size. I want to study into the cause.

This patchset allows the user to define and manage groups of domains. The patch augments the xm utility with the following commands: grp-create, grp-shutdown, grp-destroy, grp-reboot, grp-pause, grp-unpause, grp-save, grp-restore, grp-join, and grp-migrate. A goal during development of group operations was to match support for common domain operations: create, shutdown, destroy, reboot, pause,

A number of build problems crept in once again. Fix them.

Hi all, this patch series makes the necessary changes to make sure that the current ARM hypercall ABI can be used as-is on 64 bit ARM platforms: - it defines xen_ulong_t as uint64_t on ARM; - it introduces a new macro to handle guest pointers, called XEN_GUEST_HANDLE_PARAM (that has size 4 bytes on aarch and is going to have size 8 bytes on aarch64); - it replaces all the occurrences of

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -

Hi all, Can dom0 have enough privilege to access domu''s kernel memory using Libvmi functions? Libvmi use xenaccess functions in fact, and as it is a user space library I''m asking this. I wanna read system call table of domu through dom0. Thanks _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
