Hmm, I don't think the problem is that init_ia32_feat_ctl() is called too late. It too is called from the BSP prior to alternative_instructions(): arch_cpu_finalize_init() | -> identify_boot_cpu() | -> identify_cpu() | -> .c_init() => init_intel() Ah, and the WARN even specifically checks for the case where there's divergence from the boot CPU: if (boot_cpu_has(feature)) WARN_ON(alternatives_patched); So I think this is a "real" warning about a misconfigured system, where VMX is fully configured in MSR_IA32_FEAT_CTL on the boot CPU, but is disabled on a secondary CPU. FWIW, KVM will play nice with such a setup, as KVM specifically checks that VMX is fully enabled all CPUs, but I would still consider this a misconfigured system. > > [ 0.055225][ T0] init_intel (arch/x86/include/asm/msr.h:146 arch/x86/include/asm/msr.h:300 arch/x86/kernel/cpu/intel.c:583 arch/x86/kernel/cpu/intel.c:687) > > [ 0.055225][ T0] identify_cpu (arch/x86/kernel/cpu/common.c:1824) > > [ 0.055225][ T0] identify_secondary_cpu (arch/x86/kernel/cpu/common.c:1949) > > [ 0.055225][ T0] smp_store_cpu_info (arch/x86/kernel/smpboot.c:333) > > [ 0.055225][ T0] start_secondary (arch/x86/kernel/smpboot.c:197 arch/x86/kernel/smpboot.c:281) > > [ 0.055225][ T0] ? __pfx_start_secondary (arch/x86/kernel/smpboot.c:231) > > [ 0.055225][ T0] common_startup_64 (arch/x86/kernel/head_64.S:421) > > [ 0.055225][ T0] </TASK> > > [ 0.055225][ T0] ---[ end trace 0000000000000000 ]--- ^ permalink raw reply [flat|nested] 22+ messages in thread

But that would just mask the underlying problem, it wouldn't actually fix anything other than making the WARN go away. Unless I'm misreading the splat+code, the issue isn't that init_ia32_feat_ctl() clears VMX late, it's that the BSP sees VMX as fully enabled, but at least one AP sees VMX as disabled. I don't see how the kernel can expect to function correctly with divergent feature support across CPUs, i.e. the WARN is a _good_ thing in this case, because it alerts the user that their system is messed up, e.g. has a bad BIOS or something. ^ permalink raw reply [flat|nested] 22+ messages in thread

Yes, and yes. There are two issues. Clearing feature flags after alternatives have been applied should not happen, and this particular issue with that box. Lemme cook up something in the coming days for the former. As to the box having misconfigured VMX settings, dmesg says: [ 0.055225][ T0] x86/cpu: VMX (outside TXT) disabled by BIOS which means this: (!tboot && !(msr & FEAT_CTL_VMX_ENABLED_OUTSIDE_SMX))) { so...

Hm, ok, after looking at this more, I think I'm going to go with patch 2 only. And patch 1 is wrong. At least for now, lemme explain: So before it, we'd do if (boot_cpu_has(feature)) WARN_ON(alternatives_patched); when clearing feature flags, meaning: if the flag is set on the BSP, that means, alternatives have patched already and we're clearing potentially on another CPU and it'll warn because it will be wrong. If we do: if (c && cpu_has(c, feature)) WARN_ON(alternatives_patched); then it would warn on *every* CPU but it doesn't need to *BECAUSE* the alternatives patching is controlled by the boot_cpu_data checks for the BSP - not the AP ones. So if the BSP doesn't have the feature, we can just as well clear it on the APs as it wouldn't have any effect on conditionals further on. Otherwise, we'll have to go and move every clear_cpu_cap() call after alternatives have patched to before that, which would be insane. I mean, we'll do that eventually but can't now. Lemme write that as a comment in the function so that we don't forget. Oh boy, I love our feature flags infra. :-\ -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette ^ permalink raw reply [flat|nested] 22+ messages in thread

I am so confused. With both patches applied, simulating VMX being disabled by BIOS, which is a _legal_ configuration, yields: ------------[ cut here ]------------ WARNING: CPU: 1 PID: 0 at arch/x86/kernel/cpu/cpuid-deps.c:118 do_clear_cpu_cap+0xf6/0x120 Modules linked in: CPU: 1 PID: 0 Comm: swapper/1 Not tainted 6.9.0-rc3-28ed6849f6ae-rev/boris-vm #389 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 RIP: 0010:do_clear_cpu_cap+0xf6/0x120 Call Trace: <TASK> init_ia32_feat_ctl+0x133/0x420 init_intel+0x11/0x330 identify_cpu+0x242/0x670 identify_secondary_cpu+0xe/0x40 smp_store_cpu_info+0x48/0x60 start_secondary+0x73/0x120 common_startup_64+0x13b/0x141 </TASK> ---[ end trace 0000000000000000 ]--- That's completely expected (by me at least), because as I said in the original thread, secondary CPUs are identified after alternatives are applied, and when VMX is disabled by BIOS, the feature flag will be initially set based on CPUID, and then cleared by init_ia32_feat_ctl(). I.e. patch 1 is wrong on multiple levels. And without _either_ patch applied, no WARN occurs, which is again expected (by me), because init_ia32_feat_ctl() runs _before_ alternative_instructions() on the boot CPU, i.e. alternatives_patched will be false when do_clear_cpu_cap() is called by the boot CPU, and the boot_cpu_has(feature) that guards the WARN will be false when do_clear_cpu_cap() is called by secondary CPUs. The only way the WARN could have fired without this series is if VMX is enabled in BIOS on the boot CPU, but disabled by BIOS on one more secondary CPUs. And _that_ is a bogus setup that (a) the kernel absolutely should WARN about, and (b) _still_ occurs with one or both patches applied. So I don't see how this series could possibly have fixed the issue Oliver encountered, nor do I see any value in moving init_ia32_feat_ctl() into early_init_intel(). ^ permalink raw reply [flat|nested] 22+ messages in thread

It'll go to the update_caps label and there it'll do: if (!cpu_has(c, X86_FEATURE_VMX)) goto update_sgx; VMX is set if I judge by the attached cpuinfo-2 so the next check comes: if ( (tboot && !(msr & FEAT_CTL_VMX_ENABLED_INSIDE_SMX)) || (!tboot && !(msr & FEAT_CTL_VMX_ENABLED_OUTSIDE_SMX))) { if (IS_ENABLED(CONFIG_KVM_INTEL)) pr_err_once("VMX (%s TXT) disabled by BIOS\n", tboot ? "inside" : "outside"); clear_cpu_cap(c, X86_FEATURE_VMX); tboot is 0, so the second conditional: (!tboot && !(msr & FEAT_CTL_VMX_ENABLED_OUTSIDE_SMX)) FEAT_CTL_VMX_ENABLED_OUTSIDE_SMX, bit 2 is set. So that conditional is not true either. And the pr_err_once() doesn't appear in dmesg. BUT(!), look what the original dmesg said: [ 0.055225][ T0] x86/cpu: VMX (outside TXT) disabled by BIOS So that FEAT_CTL_VMX_ENABLED_OUTSIDE_SMX bit was not set back then. Why? Oliver, have you done any BIOS config changes in the meantime? This all looks really weird. The other possibility would be if something changed between -rc3 (the branch x86/alternatives is based on) and -rc7. Unlikely but by now everything's possible. What could also be the case is, the BSP's FEAT_CTL is 0x0 (unconfigured, whatever), we'd go in, set FEAT_CTL_LOCKED and that'll lock the bit in all FEAT_CTLs on all cores, then it'll set FEAT_CTL_VMX_ENABLED_OUTSIDE_SMX. I'm presuming microcode forces this and am obviously grasping at straws... Then CPU1 will come, FEAT_CTL_LOCKED will be set but FEAT_CTL_VMX_ENABLED_OUTSIDE_SMX won't be set, leading to the warn. But then again, SDM says that that MSR's scope is "Thread" which means, locking that MSR on the BSP won't have effect on the same MSR on the other HT thread. Weird. Ok, here's a bit modified debug patch ontop of the alternatives branch: https://git.kernel.org/pub/scm/linux/kernel/git/bp/bp.git/log/?h=feat_ctl please run it and send me dmesg again.

In both traces, FEAT_CTL.LOCKED is '1' before init_ia32_feat_ctl() runs, i.e. the MSR was already locked by BIOS. And that is by far the most common scenario, it's all but unheard of for BIOS to leave FEAT_CTL unlocked. For giggles, I hacked QEMU to simulate FEAT_CTL being (a) unlocked by BIOS and (b) locked with VMX disabled. For both (a) and (b), an -rc3 based kernel behaves as expected, i.e. configures the MSR correctly for (a), and complains once on the BSP about VMX being disabled for (b). Neither case triggers the WARN_ON() alternatives being applied. Oliver, are you able to reproduce the WARN using the "original" kernel? If not, then I don't think it's more time looking at this from a kernel perspective, as it's more or less guaranteed to be some sort of environmental issue. ^ permalink raw reply [flat|nested] 22+ messages in thread

Why? > > Oliver, have you done any BIOS config changes in the meantime? we really don't do any manual change recently, however, per your reminding, we rerun tests on both ee8962082a and its parent v6.9-rc3 again. while we made original report, we always saw below for both commits. "x86/cpu: VMX (outside TXT) disabled by BIOS" by rerun today, we cannot see it again, on both commits. then for ee8962082a, the reported WARNING:at_arch/x86/kernel/cpu/cpuid-deps.c:#do_clear_cpu_cap disappeared also while no "x86/cpu: VMX (outside TXT) disabled by BIOS" we are using kexec to boot into kernel, and the kernel images keep same, so we are sure this strage phenomenon is not caused by kernel build. now we doubt it's really a bios issue, we found another similar machine, which also show "x86/cpu: VMX (outside TXT) disabled by BIOS", but after several rounds of cold reboot, the message disappeared, too. we will investigate this BIOS further and avoid this kind of misleading report in the future. sorry again :( On Tue, May 07, 2024 at 01:48:14PM +0200, Borislav Petkov wrote: > From: Borislav Petkov <bp@alien8.de> > To: Oliver Sang <oliver.sang@intel.com> > Cc: Sean Christopherson <seanjc@google.com>, oe-lkp@lists.linux.dev, > lkp@intel.com, linux-kernel@vger.kernel.org, x86@kernel.org, > Ingo Molnar <mingo@kernel.org>, Srikanth Aithal <sraithal@amd.com> > Bcc: bp@alien8.de > Subject: Re: [tip:x86/alternatives] [x86/alternatives] ee8962082a: > WARNING:at_arch/x86/kernel/cpu/cpuid-deps.c:#do_clear_cpu_cap > Reply-To: > In-Reply-To: <ZjnTW4XQwVHEiSaW@xsang-OptiPlex-9020> > > On Tue, May 07, 2024 at 03:08:11PM +0800, Oliver Sang wrote: > > I applied the debug pach ontop of lastest Linus master: > > > > 1621a826233a7 debug patch from Boris for ee8962082a > > dccb07f2914cd (HEAD, linus/master) Merge tag 'for-6.9-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux > > > > attached dmesg and cpuinfo (a little diff, so I attached it again) > > Thanks, now what are we seeing here: > > [ 0.763720][ T0] x86/cpu: init_ia32_feat_ctl: CPU0: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU1: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU2: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU3: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU4: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU5: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU6: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU7: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU8: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU9: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU10: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU11: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU12: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU13: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU14: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU15: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU16: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU17: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU18: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU19: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU20: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU21: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU22: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU23: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU24: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU25: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU26: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU27: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU28: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU29: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU30: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU31: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU32: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU33: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU34: FEAT_CTL: 0x5, tboot: 0 > [ 0.055231][ T0] x86/cpu: init_ia32_feat_ctl: CPU35: FEAT_CTL: 0x5, tboot: 0 > > So following the code in init_ia32_feat_ctl(), the BSP'll get to > > if (msr & FEAT_CTL_LOCKED) > goto update_caps;
