This reverts commit 9e46e4dcd9d6cd88342b028dbfa5f4fb7483d39c.

kbuild reports a warning in memblock_remove_region() because of a false
positive caused by partial reset of the memblock state.

Doing the full reset will remove the false positives, but will allow
late use of memblock_free() to go unnoticed, so it is better to revert
the offending commit.

16 months agomm/mempolicy: Take VMA lock before replacing policy
Jann Horn [Fri, 28 Jul 2023 04:13:21 +0000 (06:13 +0200)]
mm/mempolicy: Take VMA lock before replacing policy

mbind() calls down into vma_replace_policy() without taking the per-VMA
locks, replaces the VMA's vma->vm_policy pointer, and frees the old
policy.  That's bad; a concurrent page fault might still be using the
old policy (in vma_alloc_folio()), resulting in use-after-free.

Normally this will manifest as a use-after-free read first, but it can
result in memory corruption, including because vma_alloc_folio() can
call mpol_cond_put() on the freed policy, which conditionally changes
the policy's refcount member.

This bug is specific to CONFIG_NUMA, but it does also affect non-NUMA
systems as long as the kernel was built with CONFIG_NUMA.

mm: lock_vma_under_rcu() must check vma->anon_vma under vma lock

lock_vma_under_rcu() tries to guarantee that __anon_vma_prepare() can't
be called in the VMA-locked page fault path by ensuring that
vma->anon_vma is set.

However, this check happens before the VMA is locked, which means a
concurrent move_vma() can concurrently call unlink_anon_vmas(), which
disassociates the VMA's anon_vma.

This means we can get UAF in the following scenario:

  THREAD 1                   THREAD 2
  ========                   ========
  <page fault>
    lock_vma_under_rcu()

This is a security bug if you can hit it, although an attacker would
have to win two races at once where the first race window is only a few
instructions wide.

The solution is to not increment the refcount on the IOMMUFD_DESTROY path
at all. Instead use the xa_lock to serialize everything. The refcount
check == 1 and xa_erase can be done under a single critical region. This
avoids the need for any refcount incrementing.

It has the downside that if userspace races destroy with other operations
it will get an EBUSY instead of waiting, but this is kind of racing is
already dangerous.

16 months agomm: suppress mm fault logging if fatal signal already pending
Linus Torvalds [Tue, 25 Jul 2023 16:38:32 +0000 (09:38 -0700)]
mm: suppress mm fault logging if fatal signal already pending

Commit eda0047296a1 ("mm: make the page fault mmap locking killable")
intentionally made it much easier to trigger the "page fault fails
because a fatal signal is pending" situation, by having the mmap locking
fail early in that case.

We have long aborted page faults in other fatal cases when the actual IO
for a page is interrupted by SIGKILL - which is particularly useful for
the traditional case of NFS hanging due to network issues, but local
filesystems could cause it too if you happened to get the SIGKILL while
waiting for a page to be faulted in (eg lock_folio_maybe_drop_mmap()).

So aborting the page fault wasn't a new condition - but it now triggers
earlier, before we even get to 'handle_mm_fault()'.  And as a result the
error doesn't go through our 'fault_signal_pending()' logic, and doesn't
get filtered away there.

Normally you'd never even notice, because if a fatal signal is pending,
the new SIGSEGV we send ends up being ignored anyway.

But it turns out that there is one very noticeable exception: if you
enable 'show_unhandled_signals', the aborted page fault will be logged
in the kernel messages, and you'll get a scary line looking something
like this in your logs:

  pverados[2183248]: segfault at 55e5a00f9ae0 ip 000055e5a00f9ae0 sp 00007ffc0720bea8 error 14 in perl[55e5a00d4000+195000] likely on CPU 10 (core 4, socket 0)

which is rather misleading.  It's not really a segfault at all, it's
just "the thread was killed before the page fault completed, so we
aborted the page fault".

Fix this by just making it clear that a pending fatal signal means that
any new signal coming in after that is implicitly handled.  This will
avoid the misleading logging, since now the signal isn't 'unhandled' any
more.

igc: Fix Kernel Panic during ndo_tx_timeout callback

The Xeon validation group has been carrying out some loaded tests
with various HW configurations, and they have seen some transmit
queue time out happening during the test. This will cause the
reset adapter function to be called by igc_tx_timeout().
Similar race conditions may arise when the interface is being brought
down and up in igc_reinit_locked(), an interrupt being generated, and
igc_clean_tx_irq() being called to complete the TX.

When the igc_tx_timeout() function is invoked, this patch will turn
off all TX ring HW queues during igc_down() process. TX ring HW queues
will be activated again during the igc_configure_tx_ring() process
when performing the igc_up() procedure later.

This patch also moved existing igc_disable_tx_ring_hw() to avoid using
forward declaration.

A FDB entry can't be modified so it needs to be removed and insert again

To detect if an entry already exist, the SEARCH operation is used and we

  the opposite.
- When a FDB entry doesn't exist, aging was never actually set to the
  STATIC value resulting in allocating an invalid entry.

Fix both problem by adding aging support to the function, calling the

Christian Marangi [Mon, 24 Jul 2023 03:25:28 +0000 (05:25 +0200)]
net: dsa: qca8k: enable use_single_write for qca8xxx

The qca8xxx switch supports 2 way to write reg values, a slow way using
mdio and a fast way by sending specially crafted mgmt packet to
read/write reg.

The fast way can support up to 32 bytes of data as eth packet are used
to send/receive.

This correctly works for almost the entire regmap of the switch but with
the use of some kernel selftests for dsa drivers it was found a funny
and interesting hw defect/limitation.

For some specific reg, bulk write won't work and will result in writing
only part of the requested regs resulting in half data written. This was
especially hard to track and discover due to the total strangeness of
the problem and also by the specific regs where this occurs.

This occurs in the specific regs of the ATU table, where multiple entry
needs to be written to compose the entire entry.
It was discovered that with a bulk write of 12 bytes on
QCA8K_REG_ATU_DATA0 only QCA8K_REG_ATU_DATA0 and QCA8K_REG_ATU_DATA2
were written, but QCA8K_REG_ATU_DATA1 was always zero.
Tcpdump was used to make sure the specially crafted packet was correct
and this was confirmed.

The problem was hard to track as the lack of QCA8K_REG_ATU_DATA1
resulted in an entry somehow possible as the first bytes of the mac
address are set in QCA8K_REG_ATU_DATA0 and the entry type is set in
QCA8K_REG_ATU_DATA2.

Funlly enough writing QCA8K_REG_ATU_DATA1 results in the same problem
with QCA8K_REG_ATU_DATA2 empty and QCA8K_REG_ATU_DATA1 and
QCA8K_REG_ATU_FUNC correctly written.
A speculation on the problem might be that there are some kind of
indirection internally when accessing these regs and they can't be
accessed all together, due to the fact that it's really a table mapped
somewhere in the switch SRAM.

Even more funny is the fact that every other reg was tested with all
kind of combination and they are not affected by this problem. Read
operation was also tested and always worked so it's not affected by this
problem.

The problem is not present if we limit writing a single reg at times.

To handle this hardware defect, enable use_single_write so that bulk
api can correctly split the write in multiple different operation
effectively reverting to a non-bulk write.

16 months agonet: ipa: only reset hashed tables when supported
Alex Elder [Mon, 24 Jul 2023 22:40:55 +0000 (17:40 -0500)]
net: ipa: only reset hashed tables when supported

Last year, the code that manages GSI channel transactions switched
from using spinlock-protected linked lists to using indexes into the
ring buffer used for a channel.  Recently, Google reported seeing
transaction reference count underflows occasionally during shutdown.

Doug Anderson found a way to reproduce the issue reliably, and
bisected the issue to the commit that eliminated the linked lists
and the lock.  The root cause was ultimately determined to be
related to unused transactions being committed as part of the modem
shutdown cleanup activity.  Unused transactions are not normally
expected (except in error cases).

The modem uses some ranges of IPA-resident memory, and whenever it
shuts down we zero those ranges.  In ipa_filter_reset_table() a
transaction is allocated to zero modem filter table entries.  If
hashing is not supported, hashed table memory should not be zeroed.
But currently nothing prevents that, and the result is an unused
transaction.  Something similar occurs when we zero routing table
entries for the modem.

By preventing any attempt to clear hashed tables when hashing is not
supported, the reference count underflow is avoided in this case.

Note that there likely remains an issue with properly freeing unused
transactions (if they occur due to errors).  This patch addresses
only the underflows that Google originally reported.

Kuniyuki Iwashima [Mon, 24 Jul 2023 21:34:25 +0000 (14:34 -0700)]
af_packet: Fix warning of fortified memcpy() in packet_getname().

syzkaller found a warning in packet_getname() [0], where we try to
copy 16 bytes to sockaddr_ll.sll_addr[8].

Some devices (ip6gre, vti6, ip6tnl) have 16 bytes address expressed
by struct in6_addr.  Also, Infiniband has 32 bytes as MAX_ADDR_LEN.

The write seems to overflow, but actually not since we use struct
sockaddr_storage defined in __sys_getsockname() and its size is 128
(_K_SS_MAXSIZE) bytes.  Thus, we have sufficient room after sll_addr[]
as __data[].

To avoid the warning, let's add a flex array member union-ed with
sll_addr.

Another option would be to use strncpy() and limit the copied length
to sizeof(sll_addr), but it will return the partial address and break
an application that passes sockaddr_storage to getsockname().

af_unix: Fix fortify_panic() in unix_bind_bsd().

syzkaller found a bug in unix_bind_bsd() [0].  We can reproduce it
by bind()ing a socket on a path with length 108.

108 is the size of sun_addr of struct sockaddr_un and is the maximum
valid length for the pathname socket.  When calling bind(), we use
struct sockaddr_storage as the actual buffer size, so terminating
sun_addr[108] with null is legitimate as done in unix_mkname_bsd().

However, strlen(sunaddr) for such a case causes fortify_panic() if
CONFIG_FORTIFY_SOURCE=y.  __fortify_strlen() has no idea about the
actual buffer size and see the string as unterminated.

Let's use strnlen() to allow sun_addr to be unterminated at 107.

macvlan: add forgotten nla_policy for IFLA_MACVLAN_BC_CUTOFF

The previous commit 954d1fa1ac93 ("macvlan: Add netlink attribute for
broadcast cutoff") added one additional attribute named
IFLA_MACVLAN_BC_CUTOFF to allow broadcast cutfoff.

However, it forgot to describe the nla_policy at macvlan_policy
(drivers/net/macvlan.c). Hence, this suppose NLA_S32 (4 bytes) integer
can be faked as empty (0 bytes) by a malicious user, which could leads
to OOB in heap just like CVE-2023-3773.

To fix it, this commit just completes the nla_policy description for
IFLA_MACVLAN_BC_CUTOFF. This enforces the length check and avoids the
potential OOB read.

platform/x86: msi-laptop: Fix rfkill out-of-sync on MSI Wind U100

Only the HW rfkill state is toggled on laptops with quirks->ec_read_only
(so far only MSI Wind U90/U100). There are, however, a few issues with
the implementation:

1. The initial HW state is always unblocked, regardless of the actual
   state on boot, because msi_init_rfkill only sets the SW state,
   regardless of ec_read_only.

2. The initial SW state corresponds to the actual state on boot, but it
   can't be changed afterwards, because set_device_state returns
   -EOPNOTSUPP. It confuses the userspace, making Wi-Fi and/or Bluetooth
   unusable if it was blocked on boot, and breaking the airplane mode if
   the rfkill was unblocked on boot.

Address the above issues by properly initializing the HW state on
ec_read_only laptops and by allowing the userspace to toggle the SW
state. Don't set the SW state ourselves and let the userspace fully
control it. Toggling the SW state is a no-op, however, it allows the
userspace to properly toggle the airplane mode. The actual SW radio
disablement is handled by the corresponding rtl818x_pci and btusb
drivers that have their own rfkills.

Tested on MSI Wind U100 Plus, BIOS ver 1.0G, EC ver 130.

ALSA: usb-audio: Add quirk for Microsoft Modern Wireless Headset

Microsoft Modern Wireless Headset (appearing on the host as "Microsoft
USB Link") has a playback and a capture mixer volume/switch, but they
are fairly broken.  The descriptor reports wrong dB ranges for
playback, and the capture volume/switch don't influence on the actual
recording at all.  Moreover, there seem instabilities in the
connection, and at best, we should disable the runtime PM.

So this ended up with a quirk entry for:
- Correct the playback dB range;
  I picked up some reasonable values but it's a guess work
- Disable the capture mixer;
  it's completely useless and confuses PA/PW
- Suppress get-sample-rate, apply the delay for message handling,
  and suppress the auto-suspend

The behavior of the wheel control on the headset is somehow flaky,
too, but it's an issue of HID.
