The lmsw instruction can be used to set CR0_PE, but can never clear it, once set. Currently, as far as I can see, there is no provision to keep lmsw from clearing CR0_PE, either in the vmx code or in x86_emulate code (which is used by SVM to emulate lmsw). This patch fixes this issue. Signed-off-by: Trolle Selander <trolle.selander@eu.citrix.com>

Changes from v1: - Define new struct hvm_trap to represent information of trap, include instruction length. - Renames hvm_inject_exception to hvm_inject_trap. Then define a couple of wrappers around that function for existing callers, so that their parameter lists actually *shrink*. This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP),

This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP), INTn instruction emulation. Introduce new function vmx_inject_sw_exception() which deliver the software excetion, software interrupt and privileged software exception. Split hardware exception as a seperate function(old function vmx_inject_hw_exception()). Also Passed down intruction length

Hi all, I am trying to perform single-stepping and instruction emulation both in Xen-3.2.1. I am using the following approach: First, I mark a guest page "not present" inside the shadow page table so that I could intercept any operation that involves this page. When the guest tries to access that page, it faults and control goes to Xen (sh_page_fault function). There, I emulate that

Change from v2: re-written code in ''vmx_intr_assist'' into if()/else if() sequence to make code change easy to review. Virtual interrupt delivery avoids Xen to inject vAPIC interrupts manually, which is fully taken care of by the hardware. This needs some special awareness into existing interrupr injection path: For pending interrupt from vLAPIC, instead of direct injection, we

Hi R experts, I have been using ReML as follows... model<-lmer(late.growth~mtf+year+treat+hatch.day+hatch.day:year+hatch.day:treat+ mtf:treat+ treat:year+ year:treat:mtf+(1|fybrood), data = A) then I wanted to plot the results of the three way interaction using lines() as follows... tmp<-as.vector(fixef(model)) graph1<-plot(mtf,fitted(f2), xlab=list("Brood Size"),

Hi Bastian, Ian, while I was working on the recent batch of security updates I noticed that the obvious backport of the related patch caused an HVM guest to be crashed as soon as a user inside that guest tried to ptrace a child process. While talking to Jan, I realized that in 4.2 the inject exception code subtly changed in a way that treats TRAP_debug as a HW event (that is triggered by no

Hi, Attached patch implements the VMCB cleanbits SVM feature. Upcoming AMD CPUs introduce them and they are basically hints for the CPU which vmcb values can be re-used from the previous VMRUN instruction. Each bit represents a certain set of fields in the VMCB. Setting a bit tells the cpu it can re-use the cached value from the previous VMRUN. Clearing a bit tells the cpu to reload the values

Hello, I am trying to join a third domain controller to an existing Samba 4 domain (sernet samba 4.2.1-17.el6.x86_64) and we're hitting a problem that looks like some bad replication data on certain objects. We get part way through replicating the tree and then it dies on a Sudo Rule object: [root at dc03 ~]# /usr/bin/samba-tool domain join EXAMPLE.COM DC -U Administrator

hi,all has anyone set the eflags.TF of vm? I want to introdeuce a VM into single-step by setting the eflags.TF of vm, then I disassemble the bytes at RIP to figure out what''s going on . I have set the trap flag ,but I didn''t achieve what I want. First, I only get hlt,mov, rdtsc, clts, in, out . Second, the VM always crash. does anyone have experience and give

Hi Henrik, I'm sorry to be bothering you, but there is something that I have been stuck with for a while now. I am trying to create a class like : setConstructorS3("MyPTCM",function(tokenslist=0) { extend(Object(), "MyPTCM", .gamma = 0.0, .rho = 0.0, .phi = 0.0, .tokenslist = tokenslist, .uniquetokens = unique(tokenslist),

Hello, We're using Samba 4.1.11 as domain controllers and over the past two weeks I've run into several issues with unrelated Windows software, the problems of which all point to Kerberos authentication and SPNs as being somehow involved. If there are many more issues it might start to get politically difficult *not* to blame the DCs, and I don't want to point fingers at Samba. Are

Fix the mistake for debug exception(#DB), overflow exception(#OF; generated by INTO) and int 3(#BP) instruction emulation. For INTn (CD ib), it should use type 4 (software interrupt). For INT3 (CC; NOT CD ib with ib=3) and INTO (CE; NOT CD ib with ib=4), it should use type 6 (software exception). For other exceptions (#DE, #DB, #BR, #UD, #NM, #TS, #NP, #SS, #GP, #PF, #MF, #AC, #MC, and #XM), it

Hardware Supermicro X7DAE (AHCI BIOS) dual Intel Woodcrest processors, 6 x Western Digital Raptor SATA drives. I have installed b62 running 64 bit succesfully on a PATA drive. The BIOS is configured to access the SATA drives in native mode using hte AHCI Bios. I have 6 SATA II drives accessed via the Solaris AHCI driver. I have created a ZFS file system across all 6 drives. This works fine until

Hello, We are using the account lockout feature in Samba 4.2. Unfortunately my own account is being locked out overnight and I can't figure out where from :-( Is there a level of logging on a Samba4 DC I can use to record the source address of any authentication failures, be they with Kerberos or native LDAP?

Hello, Quick observation after recently updating all DC's to 4.2.0 from 4.1.17. Several users received the notice "account is currently locked out" after entering their password once. I updated the policy to a minimum of 3 attempts before any user logged in initially. I opened Microsoft ADUC tool and clicked the box to unlock their account. This resulted in the user receiving

Hi James, We use Samba 4.2 DCs and have Linux talking to the DC fine. This is using Kerberos via SSSD on CentOS 6 and various Fedoras - Password expiry works, nested Groups work, Sudo rules and Netgroups can be placed inside the AD tree as well. A combination of the samba-tool command and pdbedit can achieve most things, however you will still need the Windows Management tools to interact with
