USB and Thunderbolt fixes for 7.1-rc6
Here is a set of USB fixes and new device ids for 7.1-rc6. Nothing
major in here, just lots of tiny fixes for reported issues found by
users and some older patches found by some scanning tools. Included in
here are:
- typec fixes found by fuzzers that have decided to finally look at
that device interaction path (i.e. before a driver is bound to a
device).
- typec fixes for issues found by users
- thunderbolt driver fixes for reported problems
- cdns3 driver fixes
- dwc3 driver fixes
- new device quirks added
- usb serial driver fixes for broken devices
- other small driver fixes
All of these have been in linux-next for over a week with no reported
issues.

Quick follow up, nothing super urgent here. Main reason I'm sending
this out is because the IPsec and Bluetooth PRs did not make it
yesterday. I don't want to have to send you all of this + whatever
comes next week, for rc7. The fixes under "Previous releases -
regressions" are for real user-reported regressions from v7.0.
Previous releases - regressions:
- Revert "ipv6: preserve insertion order for same-scope addresses"
- xfrm: move policy_bydst RCU sync, a fix which added a sync RCU
on netns exit got backported to stable and was causing serious
accumulation of dying netns's for real workloads
- pcs-mtk-lynxi: fix bpi-r3 serdes configuration
Previous releases - always broken:
- usual grab bag of race, locking and leak fixes for Bluetooth
- handful of page handling fixes for IPsec

drm/gem: fix race between change_handle and handle_delete
drm_gem_change_handle_ioctl leaves the old handle live in the IDR
during the window between spin_unlock(table_lock) and the final
spin_lock(table_lock). A concurrent drm_gem_handle_delete on the old

wireguard: send: append trailer after expanding head
With how this is currently written, we add the trailer, zero it out, and
then add the header space on. If that header space requires a
reallocation + copy, the zeros in the trailer aren't copied, because the
skb len hasn't actually been yet expanded to cover that. Instead add the
padding at the end of the process rather than at the beginning.

Revert "ipv6: preserve insertion order for same-scope addresses"
Chris Adams reported that preserving insertion order for same-scope addresses is causing SSH connections to be dropped after stopping a VM while running NetworkManager. NetworkManager caches the IPv6 address configuration, when a RA arrives, it determines the list of addresses to configure and checks if the addresses are already in the right order in the kernel. If they aren't, NetworkManager removes and re-adds them to achieve the desired order. As the order changes, NetworkManager is confused and reconfigures the addresses on every update. In addition, this would also affect to cloud tooling that relies on IPv6 addresses order to identify primary and secondaries addresses. This reverts commit |

net: skbuff: fix pskb_carve leaking zcopy pages
When SKBFL_MANAGED_FRAG_REFS is set, frag pages are not refcounted but
their lifetime is controlled by the attached ubuf_info. To make a copy
of the skb_shared_info, we either should clear the flag and reference
the frags, or keep the flag and have frags unreferenced.
pskb_carve_inside_header() and pskb_carve_inside_nonlinear() don't
follow the rule and thus can leak page references. Let's clear
SKBFL_MANAGED_FRAG_REFS from the original skb to fix it. It's the
simplest way to address it, but there are more performant ways to do
that if it ever becomes a problem.

bpf: sockmap: fix tail fragment offset in bpf_msg_push_data
When bpf_msg_push_data() inserts data in the middle of a scatterlist
entry, it splits the original entry into a left fragment and a right
fragment.
The right fragment offset is page-local, but the code advances it with
`start`, which is the message-global insertion point. For inserts into a
non-first SG entry, this over-advances the offset and leaves the split
layout inconsistent.
Advance the right fragment offset by the fragment-local delta,
`start - offset`, which matches the length removed from the front of the
original entry.

vsock/virtio: bind uarg before filling zerocopy skb
virtio_transport_send_pkt_info() allocates or reuses the zerocopy uarg
before entering the send loop, but virtio_transport_alloc_skb() still
fills the skb before it inherits that uarg. When fixed-buffer vectored
zerocopy hits MAX_SKB_FRAGS, io_sg_from_iter() may partially attach
managed frags and return -EMSGSIZE. The rollback path call kfree_skb()
to free an skb that carries SKBFL_MANAGED_FRAG_REFS but no uarg, so
skb_release_data() falls through to ordinary frag unref.
Pass the uarg into virtio_transport_alloc_skb() and bind it immediately
before virtio_transport_fill_skb(). This keeps control or no-payload skbs
untouched while ensuring success and rollback share one lifetime rule.

KVM: SEV: Use READ_ONCE() when reading entries/indices from PSC buffer
Use READ_ONCE() when reading entries/indices from the guest-accessible
Page State Change buffer to defend against TOCTOU bugs.
Don't bother with READ_ONCE()/WRITE_ONCE() for cases where KVM is writing
(and not consuming the result!), as the guest isn't supposed to touch the
buffer while it's being processed. I.e. using READ_ONCE() is all about
protecting against misbehaving guests.

KVM: SEV: Compute the correct max length of the in-GHCB scratch area
When setting the length of the GHCB scratch area, and the area is in the
GHCB shared buffer, set the effective length of the scratch area to the max
possible size given the start of the guest-provided pointer, and the end of
the shared buffer.
The code was "fine" when first introduced, as KVM doesn't consult the
length of the buffer when emulating MMIO, because the passed in @len always
specifies the *max* size required. But for PSC requests, the incoming @len
is just the minimum length (to process the header), and KVM needs to know
the full size of the scratch area to avoid buffer overflows (spoiler alert).
Opportunistically rename @len => @min_len to better reflect its role.

KVM: SEV: Use the size of the PSC header as the minimum size for PSC requests
When handling a Page State Change (PSC) #VMGEXIT use the size of the PSC
header as the minimum size for the scratch area. Per the GHCB spec, PSC
requests do NOT provide the length, i.e. using control->exit_info_2 for the
length is completely made up behavior. The existing code "works", e.g.
even though Linux-as-a-guest always passes '0', because KVM doesn't do
anything with the length when the request is in the GHCB's shared buffer.
Use the header as the min length. Once the header is retrieved, KVM can
use the specified indices to compute the full size of the request.

KVM: SEV: Require in-GHCB scratch area if GHCB v2+ is in use
As per the GHCB spec, when using GHCB v2+ require the software scratch area
to reside in the GHCB's shared buffer. Note, things like Page State Change
(PSC) requests _rely_ on this behavior, as the guest can't provide a length
when making the request, i.e. the size of the guest payload is bounded by
the size of the shared buffer.
Failure to force usage of the GHCB, and a slew of other flaws, lets a
malicious SNP guest corrupt host kernel heap memory, and leak host heap
layout information.
setup_vmgexit_scratch() allocates a buffer via kvzalloc(exit_info_2),
where exit_info_2 is guest-controlled. With exit_info_2=24, this yields
a 24-byte allocation in kmalloc-cg-32 (32-byte slab objects). The buffer
holds an 8-byte psc_hdr followed by 8-byte psc_entry structs, so only
entries[0] and entries[1] are in-bounds.
snp_begin_psc() validates end_entry against VMGEXIT_PSC_MAX_COUNT (253)
but NOT against the actual buffer size:
idx_end = hdr->end_entry;
if (idx_end >= VMGEXIT_PSC_MAX_COUNT) { // checks 253, not buffer
snp_complete_psc(svm, ...);
return 1;
}
for (idx = idx_start; idx <= idx_end; idx++) {
entry_start = entries[idx]; // OOB when idx >= 2
The guest sets end_entry=10+, causing the host to iterate entries[2+]
which are OOB into adjacent slab objects. For each OOB entry:
- The host reads 8 bytes (OOB READ / info leak oracle)
- If the data passes PSC validation, __snp_complete_one_psc() writes
cur_page = 1 or 512 into the entry (OOB WRITE, sev.c:3806)
- If validation fails, the error response reveals whether adjacent
memory is zero vs non-zero (information disclosure to guest)
The guest controls allocation size (exit_info_2), entry range
(cur_entry/end_entry), and can fire unlimited VMGEXITs to repeatedly
hit different slab positions.
By exploiting the variety of bugs, a malicious SEV-SNP guest can:
- OOB read adjacent kmalloc-cg-32 objects (heap layout disclosure)
- OOB write cur_page bits into adjacent objects (heap corruption)
- Trigger use-after-free conditions across VMGEXITs
E.g. with KASAN enabled, a single insmod of the PoC guest module
produces 73 KASAN reports:
BUG: KASAN: slab-out-of-bounds in snp_begin_psc+0x126/0x890

KVM x86 fixes for 7.1-rcN
- Include the kernel's linux/mman.h in KVM selftests to ensure MADV_COLLAPSE
is defined, as older libc versions may not provide it.
- Include execinfo.h if and only if KVM selftests are building against glibc,
and provide a test_dump_stack() for non-glibc builds.
- Fudge around an RCU splat in the emegerncy reboot code that is technically
a legitimate flaw, but in practice is a non-issue and fixing the flaw, e.g.
by adding locking, would incur meaningful risk, i.e. do more harm than good.
- Rate-limit global clock updates once again (but without delayed work), as
KVM was subtly relying on the old rate-limiting for NPT correction to guard
against "update storms" when running without a master clock on systems with
overcommitted CPUs.
- Fix a brown paper bag goof where KVM checked if ERAPS is "dirty" instead of
marking it dirty when emulating INVPCID.
- Flush the TLB when transitioning from xAVIC => x2AVIC to ensure the CPU TLB
doesn't contain AVIC-tagged entries for the APIC base GPA.

KVM: arm64: Correctly cap ZCR_EL2 provided by a guest hypervisor
ZCR_EL2 can be updated by a VHE guest hypervisor either using ZCR_EL2
(which traps) or ZCR_EL1 (which does not trap). KVM handles both in
different way:
- on ZCR_EL2 trap, ZCR_EL2.LEN is immediately capped at the VM's own
VL limit. This has the potential to break existing SW that relies
on the full LEN field to be stateful.
- on ZCR_EL1 access, we do absolutely nothing.
On restoring the SVE context for an L2 guest, we directly restore the
guest hypervisor's view of ZCR_EL2 into the physical ZCR_EL2. If the
guest's view of the register was updated using the ZCR_EL2 accessor,
the value has already been sanitised (with the caveat mentioned above).
But if the guest used ZCR_EL1, the raw value is written into the HW,
and the L2 guest can now access VLs that it shouldn't.
Fix all the above by moving the VL capping to the restore points,
ensuring that:
- the HW is always programmed with a capped value, irrespective of
the accessor being used,
- the ZCR_EL2.LEN field is always completely stateful, irrespective
of the accessor being used.
Additionally, move ZCR_EL2 to be a sanitised register, ensuring that
only the LEN field is actually stateful. This requires some creative
construction of the RES0 mask, as the sysreg generation script does
not yet generate RAZ/WI fields.

drm: prevent integer overflows in dumb buffer creation helpers
Fix integer overflow issues in the dumb buffer creation path: 1. drm_mode_create_dumb() does not bound width, height, or bpp before passing them to driver callbacks. Downstream helpers (e.g. drm_gem_dma_dumb_create_internal) perform pitch/size alignment in u32 arithmetic that can overflow for extreme values. Add hard limits: width and height < 8192, bpp <= 32. No legitimate software rendering use case exceeds these. 2. drm_mode_align_dumb() uses roundup(pitch, hw_pitch_align) without checking for overflow. If pitch is near U32_MAX, roundup() wraps to a small value, making subsequent check_mul_overflow() pass with a much smaller pitch than intended. Add an overflow check after roundup. 3. drm_mode_align_dumb() uses ALIGN(size, hw_size_align) which only works correctly for power-of-two alignment values. Replace with roundup() which works for any alignment.

sctp: fix race between sctp_wait_for_connect and peeloff
sctp_wait_for_connect() drops and re-acquires the socket lock while
waiting for the association to reach ESTABLISHED state. During this
window, another thread can peeloff the association to a new socket via
getsockopt(SCTP_SOCKOPT_PEELOFF), changing asoc->base.sk. After
re-acquiring the old socket lock, sctp_wait_for_connect() returns
success without noticing the migration — the caller then accesses
the association under the wrong lock in sctp_datamsg_from_user().
Add the same sk != asoc->base.sk check that sctp_wait_for_sndbuf()
already has, returning an error if the association was migrated while
we slept.
