mm: fix a potential infinite loop in start_isolate_page_range()
In isolate_single_pageblock() called by start_isolate_page_range(), there
are some pageblock isolation issues causing a potential infinite loop when
isolating a page range. This is reported by Qian Cai.
1. the pageblock was isolated by just changing pageblock migratetype
without checking unmovable pages. Calling set_migratetype_isolate() to
isolate pageblock properly.
2. an off-by-one error caused migrating pages unnecessarily, since the page
is not crossing pageblock boundary.
3. migrating a compound page across pageblock boundary then splitting the
free page later has a small race window that the free page might be
allocated again, so that the code will try again, causing an potential
infinite loop. Temporarily set the to-be-migrated page's pageblock to
MIGRATE_ISOLATE to prevent that and bail out early if no free page is
found after page migration.
An additional fix to split_free_page() aims to avoid crashing in
__free_one_page(). When the free page is split at the specified
split_pfn_offset, free_page_order should check both the first bit of
free_page_pfn and the last bit of split_pfn_offset and use the smaller
one. For example, if free_page_pfn=0x10000, split_pfn_offset=0xc000,
free_page_order should first be 0x8000 then 0x4000, instead of 0x4000 then
0x8000, which the original algorithm did.

MAINTAINERS: add Muchun as co-maintainer for HugeTLB
I have been focusing on mm for the past two years. e.g. developing, fixing bugs, reviewing related to HugeTLB system. I would like to help Mike and other people working on HugeTLB by reviewing their work. When I first introduced the vmemmmap reduction, I forgot to update MAINTAINERS file. Let's update it as well. And rename "HUGETLB FILESYSTEM" to "HUGETLB SUBSYSTEM" since some files are not only related to filesystem but also memory management (the name of FILESYSTEM cannot cover this area).

It prevents soft-lockups when an extensive amount of messages is printed. It was observed, for example, during boot of large systems with a lot of peripherals like disks or network interfaces. It prevents live-lockups that were observed, for example, when messages about allocation failures were reported and a CPU handled consoles instead of reclaiming the memory. It was hard to solve even with rate limiting because it would need to take into account the amount of messages and the speed of all consoles. It is a must to have for real time. Otherwise, any printk() might break latency guarantees. The per-console kthreads allow to handle each console on its own speed. Slow consoles do not longer slow down faster ones. And printk() does not longer unpredictably slows down various code paths. There are situations when the kthreads are either not available or not reliable, for example, early boot, suspend, or panic. In these situations, printk() uses the legacy mode and tries to handle consoles immediately. - Add documentation for the printk index. * tag 'printk-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: printk, tracing: fix console tracepoint printk: remove @console_locked printk: extend console_lock for per-console locking printk: add kthread console printers printk: add functions to prefer direct printing printk: add pr_flush() printk: move buffer definitions into console_emit_next_record() caller printk: refactor and rework printing logic printk: add con_printk() macro for console details printk: call boot_delay_msec() in printk_delay() printk: get caller_id/timestamp after migration disable printk: wake waiters for safe and NMI contexts printk: wake up all waiters printk: add missing memory barrier to wake_up_klogd() printk: cpu sync always disable interrupts printk: rename cpulock functions printk/index: Printk index feature documentation MAINTAINERS: Add printk indexing maintainers on mention of printk_index |

KVM: x86: Fix the intel_pt PMI handling wrongly considered from guest
When kernel handles the vm-exit caused by external interrupts and NMI,
it always sets kvm_intr_type to tell if it's dealing an IRQ or NMI. For
the PMI scenario, it could be IRQ or NMI.
However, intel_pt PMIs are only generated for HARDWARE perf events, and
HARDWARE events are always configured to generate NMIs. Use
kvm_handling_nmi_from_guest() to precisely identify if the intel_pt PMI
came from the guest; this avoids false positives if an intel_pt PMI/NMI
arrives while the host is handling an unrelated IRQ VM-Exit.

x86, kvm: use correct GFP flags for preemption disabled
Commit ddd7ed842627 ("x86/kvm: Alloc dummy async #PF token outside of
raw spinlock") leads to the following Smatch static checker warning:
arch/x86/kernel/kvm.c:212 kvm_async_pf_task_wake()
warn: sleeping in atomic context
arch/x86/kernel/kvm.c
202 raw_spin_lock(&b->lock);
203 n = _find_apf_task(b, token);
204 if (!n) {
205 /*
206 * Async #PF not yet handled, add a dummy entry for the token.
207 * Allocating the token must be down outside of the raw lock
208 * as the allocator is preemptible on PREEMPT_RT kernels.
209 */
210 if (!dummy) {
211 raw_spin_unlock(&b->lock);
--> 212 dummy = kzalloc(sizeof(*dummy), GFP_KERNEL);
^^^^^^^^^^
Smatch thinks the caller has preempt disabled. The `smdb.py preempt
kvm_async_pf_task_wake` output call tree is:
sysvec_kvm_asyncpf_interrupt() <- disables preempt
-> __sysvec_kvm_asyncpf_interrupt()
-> kvm_async_pf_task_wake()
The caller is this:
arch/x86/kernel/kvm.c
290 DEFINE_IDTENTRY_SYSVEC(sysvec_kvm_asyncpf_interrupt)
291 {
292 struct pt_regs *old_regs = set_irq_regs(regs);
293 u32 token;
294
295 ack_APIC_irq();
296
297 inc_irq_stat(irq_hv_callback_count);
298
299 if (__this_cpu_read(apf_reason.enabled)) {
300 token = __this_cpu_read(apf_reason.token);
301 kvm_async_pf_task_wake(token);
302 __this_cpu_write(apf_reason.token, 0);
303 wrmsrl(MSR_KVM_ASYNC_PF_ACK, 1);
304 }
305
306 set_irq_regs(old_regs);
307 }
The DEFINE_IDTENTRY_SYSVEC() is a wrapper that calls this function
from the call_on_irqstack_cond(). It's inside the call_on_irqstack_cond()
where preempt is disabled (unless it's already disabled). The
irq_enter/exit_rcu() functions disable/enable preempt.

KVM: x86: avoid calling x86 emulator without a decoded instruction
Whenever x86_decode_emulated_instruction() detects a breakpoint, it returns the value that kvm_vcpu_check_breakpoint() writes into its pass-by-reference second argument. Unfortunately this is completely bogus because the expected outcome of x86_decode_emulated_instruction is an EMULATION_* value. Then, if kvm_vcpu_check_breakpoint() does "*r = 0" (corresponding to a KVM_EXIT_DEBUG userspace exit), it is misunderstood as EMULATION_OK and x86_emulate_instruction() is called without having decoded the instruction. This causes various havoc from running with a stale emulation context. The fix is to move the call to kvm_vcpu_check_breakpoint() where it was before commit |

KVM: SVM: Use kzalloc for sev ioctl interfaces to prevent kernel data leak
For some sev ioctl interfaces, the length parameter that is passed maybe less than or equal to SEV_FW_BLOB_MAX_SIZE, but larger than the data that PSP firmware returns. In this case, kmalloc will allocate memory that is the size of the input rather than the size of the data. Since PSP firmware doesn't fully overwrite the allocated buffer, these sev ioctl interface may return uninitialized kernel slab memory.

x86/fpu: KVM: Set the base guest FPU uABI size to sizeof(struct kvm_xsave)
Set the starting uABI size of KVM's guest FPU to 'struct kvm_xsave', i.e. to KVM's historical uABI size. When saving FPU state for usersapce, KVM (well, now the FPU) sets the FP+SSE bits in the XSAVE header even if the host doesn't support XSAVE. Setting the XSAVE header allows the VM to be migrated to a host that does support XSAVE without the new host having to handle FPU state that may or may not be compatible with XSAVE. Setting the uABI size to the host's default size results in out-of-bounds writes (setting the FP+SSE bits) and data corruption (that is thankfully caught by KASAN) when running on hosts without XSAVE, e.g. on Core2 CPUs. WARN if the default size is larger than KVM's historical uABI size; all features that can push the FPU size beyond the historical size must be opt-in. ================================================================== BUG: KASAN: slab-out-of-bounds in fpu_copy_uabi_to_guest_fpstate+0x86/0x130 Read of size 8 at addr ffff888011e33a00 by task qemu-build/681 CPU: 1 PID: 681 Comm: qemu-build Not tainted 5.18.0-rc5-KASAN-amd64 #1 Hardware name: /DG35EC, BIOS ECG3510M.86A.0118.2010.0113.1426 01/13/2010 Call Trace: <TASK> dump_stack_lvl+0x34/0x45 print_report.cold+0x45/0x575 kasan_report+0x9b/0xd0 fpu_copy_uabi_to_guest_fpstate+0x86/0x130 kvm_arch_vcpu_ioctl+0x72a/0x1c50 [kvm] kvm_vcpu_ioctl+0x47f/0x7b0 [kvm] __x64_sys_ioctl+0x5de/0xc90 do_syscall_64+0x31/0x50 entry_SYSCALL_64_after_hwframe+0x44/0xae </TASK> Allocated by task 0: (stack is not available) The buggy address belongs to the object at ffff888011e33800 which belongs to the cache kmalloc-512 of size 512 The buggy address is located 0 bytes to the right of 512-byte region [ffff888011e33800, ffff888011e33a00) The buggy address belongs to the physical page: page:0000000089cd4adb refcount:1 mapcount:0 mapping:0000000000000000 index:0x0 pfn:0x11e30 head:0000000089cd4adb order:2 compound_mapcount:0 compound_pincount:0 flags: 0x4000000000010200(slab|head|zone=1) raw: 4000000000010200 dead000000000100 dead000000000122 ffff888001041c80 raw: 0000000000000000 0000000080100010 00000001ffffffff 0000000000000000 page dumped because: kasan: bad access detected Memory state around the buggy address: ffff888011e33900: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ffff888011e33980: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 >ffff888011e33a00: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc ^ ffff888011e33a80: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc ffff888011e33b00: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc ================================================================== Disabling lock debugging due to kernel taint Fixes: |

KVM: selftests: x86: Fix test failure on arch lbr capable platforms
On Arch LBR capable platforms, LBR_FMT in perf capability msr is 0x3f, so the last format test will fail. Use a true invalid format(0x30) for the test if it's running on these platforms. Opportunistically change the file name to reflect the tests actually carried out.

Qualcomm clock updates for v5.19
This introduces the LPASS clock controller driver for sc7280 and the global clock controller for SC8280XP. It adds modem reset, corrects RPM clocks and moves to floor ops for SDCC on MSM8976. It introduces clocks needed to operate the Sensor Subsystem in MSM8998. It enhances the logic for parked shared RCG2s, to avoid problems on recent platforms. And lastly it introduces a new mechanism for handling the PCIe pipe_clk, which also needs to be parked on a safe source when the PHY is turned off. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmKLnzIbHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3FAVEQANglSzCJKnhvVg+u/Z/Z gpTmxSV8uDIKv1jdrfBAmhdSXE0U7Bda21wGuJ8CVcnsg0VdCRMu9p3aLSu06xYo 3vHN4UubIFvUOr5gvd03jvPHD2DRInNnofvTOsKfvOlW7LAf4PclCXXGhTS4F2D0 kS8rumISFDU+sFzHNi4cb/+3IF000kZ+5mvyFkrmf5r23pLIRmjvN0qb5dcipSlo 6tACvY4R2lrp6GAht+ZYRnaFSsTuKpGKMHENwVPL03DK/yOOUkcZv6Y+gH9Os4El Y+sdTmfaJtXPZTyIYOTNZlI8QCCqEC3eZ1E4i1bhv2vl1OkKxwL8RqvmEJ7XtGDV FA1v8JDDtBAFI0WHt4TbQ0Y5GQ8dsmdOtf81TGjYK+hFQLdHv2vsSUfcHorArSbY emOzgb8Gkds1abvuDaSiOfPViy7Lc4oZLtR07eGvOuW5bG44bQmqGnWLufE6Nf3U BR847AMoesf0lAAUVkH0BQx5IPQWNmEsOVugKPdroWfbXvDoFlOnd7wN8S/kf36n qJUNcIg9SlGKpxJz9Shp1vB+JHdx0aKdT8GeNgU7cB+uh4hc4zhK6qUmfz/fNklu QFHnu0ZOvgwxDhziCj1ir43SZ3P20SVn46lHWA6wGn9nYlCOnl1ZM2wRI20SwkmU RK8hfa1x9rdYd/sm/jH8TCmC =nvpn -----END PGP SIGNATURE----- Merge tag 'qcom-clk-for-5.19' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into clk-qcom Pull Qualcomm clock driver updates from Bjorn Andersson: This introduces the LPASS clock controller driver for sc7280 and the global clock controller for SC8280XP.

New code for 5.19:
- Fix a couple of accounting errors in the buffered io code.
- Discontinue the practice of marking folios !uptodate and invalidating
them when writeback fails. This fixes some UAF bugs when multipage
folios are enabled, and brings the behavior of XFS/gfs/zonefs into
alignment with the behavior of all the other Linux filesystems.

Pull iomap updates from Darrick Wong:
"There's a couple of corrections sent in by Andreas for some accounting
errors.
The biggest change this time around is that writeback errors longer
clear pageuptodate nor does XFS invalidate the page cache anymore.
This brings XFS (and gfs2/zonefs) behavior in line with every other
Linux filesystem driver, and fixes some UAF bugs that only cropped up
after willy turned on multipage folios for XFS in 5.18-rc1.
Regrettably, it took all the way to the end of the 5.18 cycle to find
the source of these bugs and reach a consensus that XFS' writeback
failure behavior from 20 years ago is no longer necessary.
Summary:
- Fix a couple of accounting errors in the buffered io code.
- Discontinue the practice of marking folios !uptodate and
invalidating them when writeback fails.
This fixes some UAF bugs when multipage folios are enabled, and

"Features:
- subpage:
- support for PAGE_SIZE > 4K (previously only 64K)
- make it work with raid56
- repair super block num_devices automatically if it does not match
the number of device items
- defrag can convert inline extents to regular extents, up to now
inline files were skipped but the setting of mount option
max_inline could affect the decision logic
- zoned:
- minimal accepted zone size is explicitly set to 4MiB
- make zone reclaim less aggressive and don't reclaim if there are
enough free zones
- add per-profile sysfs tunable of the reclaim threshold
- allow automatic block group reclaim for non-zoned filesystems, with
sysfs tunables
- tree-checker: new check, compare extent buffer owner against owner
rootid
Performance:
- avoid blocking on space reservation when doing nowait direct io
writes (+7% throughput for reads and writes)
- NOCOW write throughput improvement due to refined locking (+3%)
- send: reduce pressure to page cache by dropping extent pages right
after they're processed
Core:
- convert all radix trees to xarray
- add iterators for b-tree node items
- support printk message index
- user bulk page allocation for extent buffers
- switch to bio_alloc API, use on-stack bios where convenient, other
bio cleanups
- use rw lock for block groups to favor concurrent reads
- simplify workques, don't allocate high priority threads for all
normal queues as we need only one
- refactor scrub, process chunks based on their constraints and
similarity
- allocate direct io structures on stack and pass around only
pointers, avoids allocation and reduces potential error handling
Fixes:
- fix count of reserved transaction items for various inode
operations
- fix deadlock between concurrent dio writes when low on free data
space
- fix a few cases when zones need to be finished
VFS, iomap:
- add helper to check if sb write has started (usable for assertions)
- new helper iomap_dio_alloc_bio, export iomap_dio_bio_end_io"

Merge tag 'erofs-for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs
Pull erofs (and fscache) updates from Gao Xiang:
"After working on it on the mailing list for more than half a year, we
finally form 'erofs over fscache' feature into shape. Hopefully it
could bring more possibility to the communities.
The story mainly started from a new project what we called "RAFS v6" [1]
for Nydus image service almost a year ago, which enhances EROFS to be
a new form of one bootstrap (which includes metadata representing the
whole fs tree) + several data-deduplicated content addressable blobs
(actually treated as multiple devices). Each blob can represent one
container image layer but not quite exactly since all new data can be
fully existed in the previous blobs so no need to introduce another
new blob.
It is actually not a new idea (at least on my side it's much like a
simpilied casync [2] for now) and has many benefits over per-file
blobs or some other exist ways since typically each RAFS v6 image only
has dozens of device blobs instead of thousands of per-file blobs.
It's easy to be signed with user keys as a golden image, transfered
untouchedly with minimal overhead over the network, kept in some type
of storage conveniently, and run with (optional) runtime verification
but without involving too many irrelevant features crossing the system
beyond EROFS itself. At least it's our final goal and we're keeping
working on it. There was also a good summary of this approach from the
casync author [3].
Regardless further optimizations, this work is almost done in the
previous Linux release cycles. In this round, we'd like to introduce
on-demand load for EROFS with the fscache/cachefiles infrastructure,
considering the following advantages:
- Introduce new file-based backend to EROFS. Although each image only
contains dozens of blobs but in densely-deployed runC host for
example, there could still be massive blobs on a machine, which is
messy if each blob is treated as a device. In contrast, fscache and
cachefiles are really great interfaces for us to make them work.
- Introduce on-demand load to fscache and EROFS. Previously, fscache
is mainly used to caching network-likewise filesystems, now it can
support on-demand downloading for local fses too with the exact
localfs on-disk format. It has many advantages which we're been
described in the latest patchset cover letter [4]. In addition to
that, most importantly, the cached data is still stored in the
original local fs on-disk format so that it's still the one signed
with private keys but only could be partially available. Users can
fully trust it during running. Later, users can also back up
cachefiles easily to another machine.
- More reliable on-demand approach in principle. After data is all
available locally, user daemon can be no longer online in some use
cases, which helps daemon crash recovery (filesystems can still in
service) and hot-upgrade (user daemon can be upgraded more
frequently due to new features or protocols introduced.)
- Other format can also be converted to EROFS filesystem format over
the internet on the fly with the new on-demand load feature and
mounted. That is entirely possible with on-demand load feature as
long as such archive format metadata can be fetched in advance like
stargz.
In addition, although currently our target user is Nydus image service [5],
but laterly, it can be used for other use cases like on-demand system
booting, etc. As for the fscache on-demand load feature itself,
strictly it can be used for other local fses too. Laterly we could
promote most code to the iomap infrastructure and also enhance it in
the read-write way if other local fses are interested.
Thanks David Howells for taking so much time and patience on this
these months, many thanks with great respect here again! Thanks Jeffle
for working on this feature and Xin Yin from Bytedance for
asynchronous I/O implementation as well as Zichen Tian, Jia Zhu, and
Yan Song for testing, much appeciated. We're also exploring more
possibly over fscache cache management over FSDAX for secure
containers and working on more improvements and useful features for
fscache, cachefiles, and on-demand load.
In addition to "erofs over fscache", NFS export and idmapped mount are
also completed in this cycle for container use cases as well.
Summary:
- Add erofs on-demand load support over fscache
- Support NFS export for erofs
- Support idmapped mounts for erofs
- Don't prompt for risk any more when using big pcluster
- Fix buffer copy overflow of ztailpacking feature

Pull fs idmapping updates from Christian Brauner:
"This contains two minor updates:
- An update to the idmapping documentation by Rodrigo making it
easier to understand that we first introduce several use-cases that
fail without idmapped mounts simply to explain how they can be
handled with idmapped mounts.
- When changing a mount's idmapping we now hold writers to make it
more robust.
This is similar to turning a mount ro with the difference that in
contrast to turning a mount ro changing the idmapping can only ever
be done once while a mount can transition between ro and rw as much
as it wants.
The vfs layer itself takes care to retrieve the idmapping of a
mount once ensuring that the idmapping used for vfs permission
checking is identical to the idmapping passed down to the
filesystem. All filesystems with FS_ALLOW_IDMAP raised take the
same precautions as the vfs in code-paths that are outside of
direct control of the vfs such as ioctl()s.
However, holding writers makes this more robust and predictable for
both the kernel and userspace.
This is a minor user-visible change. But it is extremely unlikely
to matter. The caller must've created a detached mount via
OPEN_TREE_CLONE and then handed that O_PATH fd to another process
or thread which then must've gotten a writable fd for that mount
and started creating files in there while the caller is still
changing mount properties. While not impossible it will be an
extremely rare corner-case and should in general be considered a
bug in the application. Consider making a mount MOUNT_ATTR_NOEXEC
or MOUNT_ATTR_NODEV while allowing someone else to perform lookups
or exec'ing in parallel by handing them a copy of the
OPEN_TREE_CLONE fd or another fd beneath that mount.
I've pinged all major users of idmapped mounts pointing out this
change and none of them have active writers on a mount while still
changing mount properties. It would've been strange if they did.
The rest and majority of the work will be coming through the overlayfs
tree this cycle. In addition to overlayfs this cycle should also see
support for idmapped mounts on erofs as I've acked a patch to this
effect a little while ago"
