Added "nokaiser" boot option: an early param like "noinvpcid". Most places now check int kaiser_enabled (#defined 0 when not CONFIG_KAISER) instead of #ifdef CONFIG_KAISER; but entry_64.S and entry_64_compat.S are using the ALTERNATIVE technique, which patches in the preferred instructions at runtime. That technique is tied to x86 cpu features, so X86_FEATURE_KAISER fabricated ("" in its comment so "kaiser" not magicked into /proc/cpuinfo). Prior to "nokaiser", Kaiser #defined _PAGE_GLOBAL 0: revert that, but be careful with both _PAGE_GLOBAL and CR4.PGE: setting them when nokaiser like when !CONFIG_KAISER, but not setting either when kaiser - neither matters on its own, but it's hard to be sure that _PAGE_GLOBAL won't get set in some obscure corner, or something add PGE into CR4. By omitting _PAGE_GLOBAL from __supported_pte_mask when kaiser_enabled, all page table setup which uses pte_pfn() masks it out of the ptes. It's slightly shameful that the same declaration versus definition of kaiser_enabled appears in not one, not two, but in three header files (asm/kaiser.h, asm/pgtable.h, asm/tlbflush.h). I felt safer that way, than with #including any of those in any of the others; and did not feel it worth an asm/kaiser_enabled.h - kernel/cpu/common.c includes them all, so we shall hear about it if they get out of synch. Cleanups while in the area: removed the silly #ifdef CONFIG_KAISER from kaiser.c; removed the unused native_get_normal_pgd(); removed the spurious reg clutter from SWITCH_*_CR3 macro stubs; corrected some comments. But more interestingly, set CR4.PSE in secondary_startup_64: the manual is clear that it does not matter whether it's 0 or 1 when 4-level-pts are enabled, but I was distracted to find cr4 different on BSP and auxiliaries - BSP alone was adding PSE, in probe_page_size_mask().

Synthetic filesystem mempressure testing has shown softlockups, with hour-long page allocation stalls, and pgd_alloc() trying for order:1 with __GFP_REPEAT in one of the backtraces each time. That's _pgd_alloc() going for a Kaiser double-pgd, using the __GFP_REPEAT common to all page table allocations, but actually having no effect on order:0 (see should_alloc_oom() and should_continue_reclaim() in this tree, but beware that ports to another tree might behave differently). Order:1 stack allocation has been working satisfactorily without __GFP_REPEAT forever, and page table allocation only asks __GFP_REPEAT for awkward occasions in a long-running process: it's not appropriate at fork or exec time, and seems to be doing much more harm than good: getting those contiguous pages under very heavy mempressure can be hard (though even without it, Kaiser does generate more mempressure). Mask out that __GFP_REPEAT inside _pgd_alloc(). Why not take it out of the PGALLOG_GFP altogether, as v4.7 commit a3a9a59d ("x86: get rid of superfluous __GFP_REPEAT") did? Because I think that might make a difference to our page table memcg charging, which I'd prefer not to interfere with at this time. hughd adds: __alloc_pages_slowpath() in the 4.4.89-stable tree handles __GFP_REPEAT a little differently than in prod kernel or 3.18.72-stable, so it may not always be exactly a no-op on order:0 pages, as said above; but I think still appropriate to omit it from Kaiser or non-Kaiser pgd.

Neel Natu points out that paranoid_entry() was wrong to assume that an entry that did not need swapgs would not need SWITCH_KERNEL_CR3: paranoid_entry (used for debug breakpoint, int3, double fault or MCE; though I think it's only the MCE case that is cause for concern here) can break in at an awkward time, between cr3 switch and swapgs, but its handling always needs kernel gs and kernel cr3. Easy to fix in itself, but paranoid_entry() also needs to convey to paranoid_exit() (and my reading of macro idtentry says paranoid_entry and paranoid_exit are always paired) how to restore the prior state. The swapgs state is already conveyed by %ebx (0 or 1), so extend that also to convey when SWITCH_USER_CR3 will be needed (2 or 3). (Yes, I'd much prefer that 0 meant no swapgs, whereas it's the other way round: and a convention shared with error_entry() and error_exit(), which I don't want to touch. Perhaps I should have inverted the bit for switch cr3 too, but did not.) paranoid_exit() would be straightforward, except for TRACE_IRQS: it did TRACE_IRQS_IRETQ when doing swapgs, but TRACE_IRQS_IRETQ_DEBUG when not: which is it supposed to use when SWITCH_USER_CR3 is split apart from that? As best as I can determine, commit 5963e317 ("ftrace/x86: Do not change stacks in DEBUG when calling lockdep") missed the swapgs case, and should have used TRACE_IRQS_IRETQ_DEBUG there too (the discrepancy has nothing to do with the liberal use of _NO_STACK and _UNSAFE_STACK hereabouts: TRACE_IRQS_OFF_DEBUG has just been used in all cases); discrepancy lovingly preserved across several paranoid_exit() cleanups, but I'm now removing it. Neel further indicates that to use SWITCH_USER_CR3_NO_STACK there in paranoid_exit() is now not only unnecessary but unsafe: might corrupt syscall entry's unsafe_stack_register_backup of %rax. Just use SWITCH_USER_CR3: and delete SWITCH_USER_CR3_NO_STACK altogether, before we make the mistake of using it again. hughd adds: this commit fixes an issue in the Kaiser-without-PCIDs part of the series, and ought to be moved earlier, if you decided to make a release of Kaiser-without-PCIDs.

Mostly this commit is just unshouting X86_CR3_PCID_KERN_VAR and X86_CR3_PCID_USER_VAR: we usually name variables in lower-case. But why does x86_cr3_pcid_noflush need to be __aligned(PAGE_SIZE)? Ah, it's a leftover from when kaiser_add_user_map() once complained about mapping the same page twice. Make it __read_mostly instead. (I'm a little uneasy about all the unrelated data which shares its page getting user-mapped too, but that was so before, and not a big deal: though we call it user-mapped, it's not mapped with _PAGE_USER.) And there is a little change around the two calls to do_nmi(). Previously they set the NOFLUSH bit (if PCID supported) when forcing to kernel context before do_nmi(); now they also have the NOFLUSH bit set (if PCID supported) when restoring context after: nothing done in do_nmi() should require a TLB to be flushed here.

Why was 4 chosen for kernel PCID and 6 for user PCID? No good reason in a backport where PCIDs are only used for Kaiser. If we continue with those, then we shall need to add Andy Lutomirski's 4.13 commit 6c690ee1 ("x86/mm: Split read_cr3() into read_cr3_pa() and __read_cr3()"), which deals with the problem of read_cr3() callers finding stray bits in the cr3 that they expected to be page-aligned; and for hibernation, his 4.14 commit f34902c5 ("x86/hibernate/64: Mask off CR3's PCID bits in the saved CR3"). But if 0 is used for kernel PCID, then there's no need to add in those commits - whenever the kernel looks, it sees 0 in the lower bits; and 0 for kernel seems an obvious choice. And I naughtily propose 128 for user PCID. Because there's a place in _SWITCH_TO_USER_CR3 where it takes note of the need for TLB FLUSH, but needs to reset that to NOFLUSH for the next occasion. Currently it does so with a "movb $(0x80)" into the high byte of the per-cpu quadword, but that will cause a machine without PCID support to crash. Now, if %al just happened to have 0x80 in it at that point, on a machine with PCID support, but 0 on a machine without PCID support... (That will go badly wrong once the pgd can be at a physical address above 2^56, but even with 5-level paging, physical goes up to 2^52.) Acked-by:

We have many machines (Westmere, Sandybridge, Ivybridge) supporting PCID but not INVPCID: on these load_new_mm_cr3() simply crashed. Flushing user context inside load_new_mm_cr3() without the use of invpcid is difficult: momentarily switch from kernel to user context and back to do so? I'm not sure whether that can be safely done at all, and would risk polluting user context with kernel internals, and kernel context with stale user externals. Instead, follow the hint in the comment that was there: change X86_CR3_PCID_USER_VAR to be a per-cpu variable, then load_new_mm_cr3() can leave a note in it, for SWITCH_USER_CR3 on return to userspace to flush user context TLB, instead of default X86_CR3_PCID_USER_NOFLUSH. Which works well enough that there's no need to do it this way only when invpcid is unsupported: it's a good alternative to invpcid here. But there's a couple of inlines in asm/tlbflush.h that need to do the same trick, so it's best to localize all this per-cpu business in mm/kaiser.c: moving that part of the initialization from setup_pcid() to kaiser_setup_pcid(); with kaiser_flush_tlb_on_return_to_user() the function for noting an X86_CR3_PCID_USER_FLUSH. And let's keep a KAISER_SHADOW_PGD_OFFSET in there, to avoid the extra OR on exit. I did try to make the feature tests in asm/tlbflush.h more consistent with each other: there seem to be far too many ways of performing such tests, and I don't have a good grasp of their differences. At first I converted them all to be static_cpu_has(): but that proved to be a mistake, as the comment in __native_flush_tlb_single() hints; so then I reversed and made them all this_cpu_has(). Probably all gratuitous change, but that's the way it's working at present. I am slightly bothered by the way non-per-cpu X86_CR3_PCID_KERN_VAR gets re-initialized by each cpu (before and after these changes): no problem when (as usual) all cpus on a machine have the same features, but in principle incorrect. However, my experiment to per-cpu-ify that one did not end well... Acked-by:

commit e1074888 upstream. Currently all of the functions that live in tlb.c are inlined on !SMP builds. One can debate whether this is a good idea (in many respects the code in tlb.c is better than the inlined UP code). Regardless, I want to add code that needs to be built on UP and SMP kernels and relates to tlb flushing, so arrange for tlb.c to be compiled unconditionally. Signed-off-by:

The kaiser update made an interesting choice, never to free any shadow page tables. Contention on global spinlock was worrying, particularly with it held across page table scans when freeing. Something had to be done: I was going to add refcounting; but simply never to free them is an appealing choice, minimizing contention without complicating the code (the more a page table is found already, the less the spinlock is used). But leaking pages in this way is also a worry: can we get away with it? At the very least, we need a count to show how bad it actually gets: in principle, one might end up wasting about 1/256 of memory that way (1/512 for when direct-mapped pages have to be user-mapped, plus 1/512 for when they are user-mapped from the vmalloc area on another occasion (but we don't have vmalloc'ed stacks, so only large ldts are vmalloc'ed). Add per-cpu stat NR_KAISERTABLE: including 256 at startup for the shared pgd entries, and 1 for each intermediate page table added thereafter for user-mapping - but leave out the 1 per mm, for its shadow pgd, because that distracts from the monotonic increase. Shown in /proc/vmstat as nr_overhead (0 if kaiser not enabled). In practice, it doesn't look so bad so far: more like 1/12000 after nine hours of gtests below; and movable pageblock segregation should tend to cluster the kaiser tables into a subset of the address space (if not, they will be bad for compaction too). But production may tell a different story: keep an eye on this number, and bring back lighter freeing if it gets out of control (maybe a shrinker). Acked-by:

We fail to see what CONFIG_KAISER_REAL_SWITCH is for: it seems to be left over from early development, and now just obscures tricky parts of the code. Delete it before adding PCIDs, or nokaiser boot option. (Or if there is some good reason to keep the option, then it needs a help text - and a "depends on KAISER", so that all those without KAISER are not asked the question.) Acked-by:

While trying to get our gold link to work, four cleanups: matched the gdt_page declaration to its definition; in fiddling unsuccessfully with PERCPU_INPUT(), lined up backslashes; lined up the backslashes according to convention in percpu-defs.h; deleted the unused irq_stack_pointer addition to irq_stack_union. Sad to report that aligning backslashes does not appear to help gold align to 8192: but while these did not help, they are worth keeping. Acked-by:

When removing the bogus comment from kaiser_remove_mapping(), I really ought to have checked the extent of its bogosity: as Neel points out, there is nothing to stop unmap_pud_range_nofree() from continuing beyond the end of a pud (and starting in the wrong position on the next). Fix kaiser_remove_mapping() to constrain the extent and advance pgd pointer correctly: use pgd_addr_end() macro as used throughout base mm (but don't assume page-rounded start and size in this case). But this bug was very unlikely to trigger in this backport: since any buddy allocation is contained within a single pud extent, and we are not using vmapped stacks (and are only mapping one page of stack anyway): the only way to hit this bug here would be when freeing a large modified ldt.

Yes, unmap_pud_range_nofree()'s declaration ought to be in a header file really, but I'm not sure we want to use it anyway: so for now just declare it inside kaiser_remove_mapping(). And there doesn't seem to be such a thing as unmap_p4d_range(), even in a 5-level paging tree. Acked-by:

Avoid perf crashes: place debug_store in the user-mapped per-cpu area instead of allocating, and use page allocator plus kaiser_add_mapping() to keep the BTS and PEBS buffers user-mapped (that is, present in the user mapping, though visible only to kernel and hardware). The PEBS fixup buffer does not need this treatment. The need for a user-mapped struct debug_store showed up before doing any conscious perf testing: in a couple of kernel paging oopses on Westmere, implicating the debug_store offset of the per-cpu area.

pjt has observed that nmi's second (nmi_from_kernel) call to do_nmi() adjusted the %rdi regs arg, rightly when CONFIG_KAISER, but wrongly when not CONFIG_KAISER. Although the minimal change is to add an #ifdef CONFIG_KAISER around the addq line, that looks cluttered, and I prefer how the first call to do_nmi() handled it: prepare args in %rdi and %rsi before getting into the CONFIG_KAISER block, since it does not touch them at all. And while we're here, place the "#ifdef CONFIG_KAISER" that follows each, to enclose the "Unconditionally restore CR3" comment: matching how the "Unconditionally use kernel CR3" comment above is enclosed.

It is absurd that KAISER should depend on SMP, but apparently nobody has tried a UP build before: which breaks on implicit declaration of function 'per_cpu_offset' in arch/x86/mm/kaiser.c. Now, you would expect that to be trivially fixed up; but looking at the System.map when that block is #ifdef'ed out of kaiser_init(), I see that in a UP build __per_cpu_user_mapped_end is precisely at __per_cpu_user_mapped_start, and the items carefully gathered into that section for user-mapping on SMP, dispersed elsewhere on UP. So, some other kind of section assignment will be needed on UP, but implementing that is not a priority: just make KAISER depend on SMP for now. Also inserted a blank line before the option, tidied up the brief Kconfig help message, and added an "If unsure, Y". Acked-by:

Kaiser only needs to map one page of the stack; and kernel/fork.c did not build on powerpc (no __PAGE_KERNEL). It's all cleaner if linux/kaiser.h provides kaiser_map_thread_stack() and kaiser_unmap_thread_stack() wrappers around asm/kaiser.h's kaiser_add_mapping() and kaiser_remove_mapping().

native_pgd_clear() uses native_set_pgd(), so native_set_pgd() must avoid setting the _PAGE_NX bit on an otherwise pgd_none() entry: usually that just generated a warning on exit, but sometimes more mysterious and damaging failures (our production machines could not complete booting). The original fix to this just avoided adding _PAGE_NX to an empty entry; but eventually more problems surfaced with kexec, and EFI mapping expected to be a problem too. So now instead change native_set_pgd() to update shadow only if _PAGE_USER: A few places (kernel/machine_kexec_64.c, platform/efi/efi_64.c for sure) use set_pgd() to set up a temporary internal virtual address space, with physical pages remapped at what Kaiser regards as userspace addresses: Kaiser then assumes a shadow pgd follows, which it will try to corrupt. This appears to be responsible for the recent kexec and kdump failures; though it's unclear how those did not manifest as a problem before. Ah, the shadow pgd will only be assumed to "follow" if the requested pgd is on an even-numbered page: so I suppose it was going wrong 50% of the time all along. What we need is a flag to set_pgd(), to tell it we're dealing with userspace. Er, isn't that what the pgd's _PAGE_USER bit is saying? Add a test for that. But we cannot do the same for pgd_clear() (which may be called to clear corrupted entries - set aside the question of "corrupt in which pgd?" until later), so there just rely on pgd_clear() not being called in the problematic cases - with a WARN_ON_ONCE() which should fire half the time if it is. But this is getting too big for an inline function: move it into arch/x86/mm/kaiser.c (which then demands a boot/compressed mod); and de-void and de-space native_get_shadow/normal_pgd() while here.
