[PATCH 6.0 01/34] nilfs2: fix NULL pointer dereference at nilfs_bmap_lookup_at_level()

[Greg Kroah-Hartman]

From: Ryusuke Konishi <konishi.ryusuke@gmail.com>

commit 21a87d88c2253350e115029f14fe2a10a7e6c856 upstream.

If the i_mode field in inode of metadata files is corrupted on disk, it
can cause the initialization of bmap structure, which should have been
called from nilfs_read_inode_common(), not to be called.  This causes a
lockdep warning followed by a NULL pointer dereference at
nilfs_bmap_lookup_at_level().

This patch fixes these issues by adding a missing sanitiy check for the
i_mode field of metadata file's inode.

[PATCH 6.0 02/34] nilfs2: fix use-after-free bug of struct nilfs_root

[Greg Kroah-Hartman]

From: Ryusuke Konishi <konishi.ryusuke@gmail.com>

commit d325dc6eb763c10f591c239550b8c7e5466a5d09 upstream.

If the beginning of the inode bitmap area is corrupted on disk, an inode
with the same inode number as the root inode can be allocated and fail
soon after.  In this case, the subsequent call to nilfs_clear_inode() on
that bogus root inode will wrongly decrement the reference counter of
struct nilfs_root, and this will erroneously free struct nilfs_root,
causing kernel oopses.

This fixes the problem by changing nilfs_new_inode() to skip reserved
inode numbers while repairing the inode bitmap.

[PATCH 6.0 03/34] nilfs2: fix leak of nilfs_root in case of writer thread creation failure

[Greg Kroah-Hartman]

From: Ryusuke Konishi <konishi.ryusuke@gmail.com>

commit d0d51a97063db4704a5ef6bc978dddab1636a306 upstream.

If nilfs_attach_log_writer() failed to create a log writer thread, it
frees a data structure of the log writer without any cleanup.  After
commit e912a5b66837 ("nilfs2: use root object to get ifile"), this causes
a leak of struct nilfs_root, which started to leak an ifile metadata inode
and a kobject on that struct.

In addition, if the kernel is booted with panic_on_warn, the above
ifile metadata inode leak will cause the following panic when the
nilfs2 kernel module is removed:

[PATCH 6.0 04/34] nilfs2: replace WARN_ONs by nilfs_error for checkpoint acquisition failure

[Greg Kroah-Hartman]

From: Ryusuke Konishi <konishi.ryusuke@gmail.com>

commit 723ac751208f6d6540191689cfbf6c77135a7a1b upstream.

If creation or finalization of a checkpoint fails due to anomalies in the
checkpoint metadata on disk, a kernel warning is generated.

This patch replaces the WARN_ONs by nilfs_error, so that a kernel, booted
with panic_on_warn, does not panic.  A nilfs_error is appropriate here to
handle the abnormal filesystem condition.

This also replaces the detected error codes with an I/O error so that
neither of the internal error codes is returned to callers.

[PATCH 6.0 05/34] nvme-pci: set min_align_mask before calculating max_hw_sectors

[Greg Kroah-Hartman]

From: Rishabh Bhatnagar <risbhat@amazon.com>

commit 61ce339f19fabbc3e51237148a7ef6f2270e44fa upstream.

If swiotlb is force enabled dma_max_mapping_size ends up calling
swiotlb_max_mapping_size which takes into account the min align mask for
the device.  Set the min align mask for nvme driver before calling
dma_max_mapping_size while calculating max hw sectors.

[PATCH 6.0 06/34] random: restore O_NONBLOCK support

[Greg Kroah-Hartman]

From: Jason A. Donenfeld <Jason@zx2c4.com>

commit cd4f24ae9404fd31fc461066e57889be3b68641b upstream.

Prior to 5.6, when /dev/random was opened with O_NONBLOCK, it would
return -EAGAIN if there was no entropy. When the pools were unified in
5.6, this was lost. The post 5.6 behavior of blocking until the pool is
initialized, and ignoring O_NONBLOCK in the process, went unnoticed,
with no reports about the regression received for two and a half years.
However, eventually this indeed did break somebody's userspace.

So we restore the old behavior, by returning -EAGAIN if the pool is not
initialized. Unlike the old /dev/random, this can only occur during
early boot, after which it never blocks again.

In order to make this O_NONBLOCK behavior consistent with other
expectations, also respect users reading with preadv2(RWF_NOWAIT) and
similar.

[PATCH 6.0 07/34] random: clamp credited irq bits to maximum mixed

[Greg Kroah-Hartman]

From: Jason A. Donenfeld <Jason@zx2c4.com>

commit e78a802a7b4febf53f2a92842f494b01062d85a8 upstream.

Since the most that's mixed into the pool is sizeof(long)*2, don't
credit more than that many bytes of entropy.

Fixes: e3e33fc2ea7f ("random: do not use input pool from hard IRQs")

[PATCH 6.0 08/34] ALSA: hda: Fix position reporting on Poulsbo

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@suse.de>

commit 56e696c0f0c71b77fff921fc94b58a02f0445b2c upstream.

Hans reported that his Sony VAIO VPX11S1E showed the broken sound
behavior at the start of the stream for a couple of seconds, and it
turned out that the position_fix=1 option fixes the issue.  It implies
that the position reporting is inaccurate, and very likely hitting on
all Poulsbo devices.

The patch applies the workaround for Poulsbo generically to switch to
LPIB mode instead of the default position buffer.

[PATCH 6.0 09/34] ALSA: hda/realtek: Add quirk for HP Zbook Firefly 14 G9 model

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@suse.de>

commit 225f6e1bc151978041595c7d2acaded3aac41f54 upstream.

HP Zbook Firefly 14 G9 model (103c:8abb) requires yet another binding
with CS35L41 codec, but with a slightly different configuration.  It's
over spi1 instead of spi0.  Create a new fixup entry for that.

[PATCH 6.0 10/34] efi: Correct Macmini DMI match in uefi cert quirk

[Greg Kroah-Hartman]

From: Orlando Chamberlain <redecorating@protonmail.com>

commit bab715bdaa9ebf28d99a6d1efb2704a30125e96d upstream.

It turns out Apple doesn't capitalise the "mini" in "Macmini" in DMI, which
is inconsistent with other model line names.

Correct the capitalisation of Macmini in the quirk for skipping loading
platform certs on T2 Macs.

Currently users get:

[PATCH 6.0 12/34] scsi: qla2xxx: Fix response queue handler reading stale packets

[Greg Kroah-Hartman]

From: Arun Easi <aeasi@marvell.com>

commit e4f8a29deb3ba30e414dfb6b09e3ae3bf6dbe74a upstream.

On some platforms, the current logic of relying on finding new packet
solely based on signature pattern can lead to driver reading stale
packets. Though this is a bug in those platforms, reduce such exposures by
limiting reading packets until the IN pointer.

[PATCH 6.0 13/34] scsi: stex: Properly zero out the passthrough command structure

[Greg Kroah-Hartman]

From: Linus Torvalds <torvalds@linux-foundation.org>

commit 6022f210461fef67e6e676fd8544ca02d1bcfa7a upstream.

The passthrough structure is declared off of the stack, so it needs to be
set to zero before copied back to userspace to prevent any unintentional
data leakage.  Switch things to be statically allocated which will fill the
unused fields with 0 automatically.

[PATCH 6.0 17/34] Revert "powerpc/rtas: Implement reentrant rtas call"

[Greg Kroah-Hartman]

From: Nathan Lynch <nathanl@linux.ibm.com>

commit f88aabad33ea22be2ce1c60d8901942e4e2a9edb upstream.

At the time this was submitted by Leonardo, I confirmed -- or thought
I had confirmed -- with PowerVM partition firmware development that
the following RTAS functions:

- ibm,get-xive
- ibm,int-off
- ibm,int-on
- ibm,set-xive

were safe to call on multiple CPUs simultaneously, not only with
respect to themselves as indicated by PAPR, but with arbitrary other
RTAS calls:

https://lore.kernel.org/linuxppc-dev/875zcy2v8o.fsf@linux.ibm.com/

Recent discussion with firmware development makes it clear that this
is not true, and that the code in commit b664db8e3f97 ("powerpc/rtas:
Implement reentrant rtas call") is unsafe, likely explaining several
strange bugs we've seen in internal testing involving DLPAR and
LPM. These scenarios use ibm,configure-connector, whose internal state
can be corrupted by the concurrent use of the "reentrant" functions,
leading to symptoms like endless busy statuses from RTAS.

Fixes: b664db8e3f97 ("powerpc/rtas: Implement reentrant rtas call")

[PATCH 6.0 18/34] Revert "crypto: qat - reduce size of mapped region"

[Greg Kroah-Hartman]

From: Giovanni Cabiddu <giovanni.cabiddu@intel.com>

commit 9c5f21b198d259bfe1191b1fedf08e2eab15b33b upstream.

This reverts commit e48767c17718067ba21fb2ef461779ec2506f845.

In an attempt to resolve a set of warnings reported by the static
analyzer Smatch, the reverted commit improperly reduced the sizes of the
DMA mappings used for the input and output parameters for both RSA and
DH creating a mismatch (map size=8 bytes, unmap size=64 bytes).

This issue is reported when CONFIG_DMA_API_DEBUG is selected, when the
crypto self test is run. The function dma_unmap_single() reports a
warning similar to the one below, saying that the `device driver frees
DMA memory with different size`.

    DMA-API: 4xxx 0000:06:00.0: device driver frees DMA memory with different size [device address=0x0000000123206c80] [map size=8 bytes] [unmap size=64 bytes]

[PATCH 6.0 19/34] random: avoid reading two cache lines on irq randomness

[Greg Kroah-Hartman]

From: Jason A. Donenfeld <Jason@zx2c4.com>

commit 9ee0507e896b45af6d65408c77815800bce30008 upstream.

In order to avoid reading and dirtying two cache lines on every IRQ,
move the work_struct to the bottom of the fast_pool struct. add_
interrupt_randomness() always touches .pool and .count, which are
currently split, because .mix pushes everything down. Instead, move .mix
to the bottom, so that .pool and .count are always in the first cache
line, since .mix is only accessed when the pool is full.

[PATCH 6.0 20/34] random: use expired timer rather than wq for mixing fast pool

[Greg Kroah-Hartman]

From: Jason A. Donenfeld <Jason@zx2c4.com>

commit 748bc4dd9e663f23448d8ad7e58c011a67ea1eca upstream.

Previously, the fast pool was dumped into the main pool periodically in
the fast pool's hard IRQ handler. This worked fine and there weren't
problems with it, until RT came around. Since RT converts spinlocks into
sleeping locks, problems cropped up. Rather than switching to raw
spinlocks, the RT developers preferred we make the transformation from
originally doing:

    do_some_stuff()
    spin_lock()
    do_some_other_stuff()
    spin_unlock()

to doing:

    do_some_stuff()
    queue_work_on(some_other_stuff_worker)

This is an ordinary pattern done all over the kernel. However, Sherry
noticed a 10% performance regression in qperf TCP over a 40gbps
InfiniBand card. Quoting her message:

> MT27500 Family [ConnectX-3] cards:
> Infiniband device 'mlx4_0' port 1 status:

> sm lid: 0x1
> state: 4: ACTIVE
> phys state: 5: LinkUp
> rate: 40 Gb/sec (4X QDR)
> link_layer: InfiniBand
>
> Cards are configured with IP addresses on private subnet for IPoIB
> performance testing.
> Regression identified in this bug is in TCP latency in this stack as reported
> by qperf tcp_lat metric:
>
> We have one system listen as a qperf server:
> [root@yourQperfServer ~]# qperf
>
> Have the other system connect to qperf server as a client (in this

Rather than incur the scheduling latency from queue_work_on, we can
instead switch to running on the next timer tick, on the same core. This
also batches things a bit more -- once per jiffy -- which is okay now
that mix_interrupt_randomness() can credit multiple bits at once.

[PATCH 6.0 21/34] wifi: cfg80211: fix u8 overflow in cfg80211_update_notlisted_nontrans()

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

commit aebe9f4639b13a1f4e9a6b42cdd2e38c617b442d upstream.

In the copy code of the elements, we do the following calculation
to reach the end of the MBSSID element:

	/* copy the IEs after MBSSID */
	cpy_len = mbssid[1] + 2;

This looks fine, however, cpy_len is a u8, the same as mbssid[1],
so the addition of two can overflow. In this case the subsequent
memcpy() will overflow the allocated buffer, since it copies 256
bytes too much due to the way the allocation and memcpy() sizes
are calculated.

Fix this by using size_t for the cpy_len variable.

This fixes CVE-2022-41674.

[PATCH 6.0 22/34] wifi: cfg80211/mac80211: reject bad MBSSID elements

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

commit 8f033d2becc24aa6bfd2a5c104407963560caabc upstream.

Per spec, the maximum value for the MaxBSSID ('n') indicator is 8,
and the minimum is 1 since a multiple BSSID set with just one BSSID
doesn't make sense (the # of BSSIDs is limited by 2^n).

Limit this in the parsing in both cfg80211 and mac80211, rejecting
any elements with an invalid value.

This fixes potentially bad shifts in the processing of these inside
the cfg80211_gen_new_bssid() function later.

I found this during the investigation of CVE-2022-41674 fixed by the
previous patch.

[PATCH 6.0 23/34] wifi: mac80211: fix MBSSID parsing use-after-free

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

commit ff05d4b45dd89b922578dac497dcabf57cf771c6 upstream.

When we parse a multi-BSSID element, we might point some
element pointers into the allocated nontransmitted_profile.
However, we free this before returning, causing UAF when the
relevant pointers in the parsed elements are accessed.

Fix this by not allocating the scratch buffer separately but
as part of the returned structure instead, that way, there
are no lifetime issues with it.

The scratch buffer introduction as part of the returned data
here is taken from MLO feature work done by Ilan.

This fixes CVE-2022-42719.

When iterating the elements here, ensure the length byte is
present before checking it to see if the entire element will
fit into the buffer.

Longer term, we should rewrite this code using the type-safe
element iteration macros that check all of this.

[PATCH 6.0 25/34] wifi: cfg80211: fix BSS refcounting bugs

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

commit 0b7808818cb9df6680f98996b8e9a439fa7bcc2f upstream.

There are multiple refcounting bugs related to multi-BSSID:
 - In bss_ref_get(), if the BSS has a hidden_beacon_bss, then
   the bss pointer is overwritten before checking for the
   transmitted BSS, which is clearly wrong. Fix this by using
   the bss_from_pub() macro.

 - In cfg80211_bss_update() we copy the transmitted_bss pointer
   from tmp into new, but then if we release new, we'll unref
   it erroneously. We already set the pointer and ref it, but
   need to NULL it since it was copied from the tmp data.

 - In cfg80211_inform_single_bss_data(), if adding to the non-
   transmitted list fails, we unlink the BSS and yet still we
   return it, but this results in returning an entry without
   a reference. We shouldn't return it anyway if it was broken
   enough to not get added there.

This fixes CVE-2022-42720.

[PATCH 6.0 26/34] wifi: cfg80211: avoid nontransmitted BSS list corruption

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

commit bcca852027e5878aec911a347407ecc88d6fff7f upstream.

If a non-transmitted BSS shares enough information (both
SSID and BSSID!) with another non-transmitted BSS of a
different AP, then we can find and update it, and then
try to add it to the non-transmitted BSS list. We do a
search for it on the transmitted BSS, but if it's not
there (but belongs to another transmitted BSS), the list
gets corrupted.

Since this is an erroneous situation, simply fail the
list insertion in this case and free the non-transmitted
BSS.

This fixes CVE-2022-42721.

[PATCH 6.0 27/34] wifi: mac80211_hwsim: avoid mac80211 warning on bad rate

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

commit 1833b6f46d7e2830251a063935ab464256defe22 upstream.

If the tool on the other side (e.g. wmediumd) gets confused
about the rate, we hit a warning in mac80211. Silence that
by effectively duplicating the check here and dropping the
frame silently (in mac80211 it's dropped with the warning).

[PATCH 6.0 28/34] wifi: mac80211: fix crash in beacon protection for P2P-device

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

commit b2d03cabe2b2e150ff5a381731ea0355459be09f upstream.

If beacon protection is active but the beacon cannot be
decrypted or is otherwise malformed, we call the cfg80211
API to report this to userspace, but that uses a netdev
pointer, which isn't present for P2P-Device. Fix this to
call it only conditionally to ensure cfg80211 won't crash
in the case of P2P-Device.

This fixes CVE-2022-42722.

[PATCH 6.0 29/34] wifi: cfg80211: update hidden BSSes to avoid WARN_ON

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

commit c90b93b5b782891ebfda49d4e5da36632fefd5d1 upstream.

When updating beacon elements in a non-transmitted BSS,
also update the hidden sub-entries to the same beacon
elements, so that a future update through other paths
won't trigger a WARN_ON().

The warning is triggered because the beacon elements in
the hidden BSSes that are children of the BSS should
always be the same as in the parent.

[PATCH 6.0 30/34] mctp: prevent double key removal and unref

[Greg Kroah-Hartman]

From: Jeremy Kerr <jk@codeconstruct.com.au>

commit 3a732b46736cd8a29092e4b0b1a9ba83e672bf89 upstream.

Currently, we have a bug where a simultaneous DROPTAG ioctl and socket
close may race, as we attempt to remove a key from lists twice, and
perform an unref for each removal operation. This may result in a uaf
when we attempt the second unref.

This change fixes the race by making __mctp_key_remove tolerant to being
called on a key that has already been removed from the socket/net lists,
and only performs the unref when we do the actual remove. We also need
to hold the list lock on the ioctl cleanup path.

This fix is based on a bug report and comprehensive analysis from
butt3rflyh4ck <butterflyhuangxx@gmail.com>, found via syzkaller.

[PATCH 6.0 32/34] Input: xpad - fix wireless 360 controller breaking after suspend

[Greg Kroah-Hartman]

From: Cameron Gutman <aicommander@gmail.com>

commit a17b9841152e7f4621619902b347e2cc39c32996 upstream.

Suspending and resuming the system can sometimes cause the out
URB to get hung after a reset_resume. This causes LED setting
and force feedback to break on resume. To avoid this, just drop
the reset_resume callback so the USB core rebinds xpad to the
wireless pads on resume if a reset happened.

A nice side effect of this change is the LED ring on wireless
controllers is now set correctly on system resume.

[PATCH 6.0 33/34] misc: pci_endpoint_test: Aggregate params checking for xfer

[Greg Kroah-Hartman]

From: Shunsuke Mie <mie@igel.co.jp>

[PATCH 6.0 34/34] misc: pci_endpoint_test: Fix pci_endpoint_test_{copy,write,read}() panic

[Greg Kroah-Hartman]

commit 8e30538eca016de8e252bef174beadecd64239f0 upstream.

The dma_map_single() doesn't permit zero length mapping. It causes a follow
panic.

A panic was reported on arm64:
