phonet/pep: refuse to enable an unbound pipe
commit 75a2f31520095600f650597c0ac41f48b5ba0068 upstream.
This ioctl() implicitly assumed that the socket was already bound to
a valid local socket name, i.e. Phonet object. If the socket was not
bound, two separate problems would occur:
1) We'd send an pipe enablement request with an invalid source object.
2) Later socket calls could BUG on the socket unexpectedly being
connected yet not bound to a valid object.

hamradio: improve the incomplete fix to avoid NPD
commit b2f37aead1b82a770c48b5d583f35ec22aabb61e upstream.
The previous commit 3e0588c291d6 ("hamradio: defer ax25 kfree after
unregister_netdev") reorder the kfree operations and unregister_netdev
operation to prevent UAF.
This commit improves the previous one by also deferring the nullify of
the ax->tty pointer. Otherwise, a NULL pointer dereference bug occurs.
Partial of the stack trace is shown below.

hamradio: defer ax25 kfree after unregister_netdev
commit 3e0588c291d6ce225f2b891753ca41d45ba42469 upstream.
There is a possible race condition (use-after-free) like below
(USE) | (FREE)
ax25_sendmsg |
ax25_queue_xmit |
dev_queue_xmit |
__dev_queue_xmit |
__dev_xmit_skb |
sch_direct_xmit | ...
xmit_one |
netdev_start_xmit | tty_ldisc_kill
__netdev_start_xmit | mkiss_close
ax_xmit | kfree
ax_encaps |
|
Even though there are two synchronization primitives before the kfree:
1. wait_for_completion(&ax->dead). This can prevent the race with
routines from mkiss_ioctl. However, it cannot stop the routine coming
from upper layer, i.e., the ax25_sendmsg.
2. netif_stop_queue(ax->dev). It seems that this line of code aims to
halt the transmit queue but it fails to stop the routine that already
being xmit.
This patch reorder the kfree after the unregister_netdev to avoid the
possible UAF as the unregister_netdev() is well synchronized and won't
return if there is a running routine.

ax25: NPD bug when detaching AX25 device
commit 1ade48d0c27d5da1ccf4b583d8c5fc8b534a3ac8 upstream.
The existing cleanup routine implementation is not well synchronized
with the syscall routine. When a device is detaching, below race could
occur.
static int ax25_sendmsg(...) {
...
lock_sock()
ax25 = sk_to_ax25(sk);
if (ax25->ax25_dev == NULL) // CHECK
...
ax25_queue_xmit(skb, ax25->ax25_dev->dev); // USE
...
}
static void ax25_kill_by_device(...) {
...
if (s->ax25_dev == ax25_dev) {
s->ax25_dev = NULL;
...
}
Other syscall functions like ax25_getsockopt, ax25_getname,
ax25_info_show also suffer from similar races. To fix them, this patch
introduce lock_sock() into ax25_kill_by_device in order to guarantee
that the nullify action in cleanup routine cannot proceed when another
socket request is pending.

mm: mempolicy: fix THP allocations escaping mempolicy restrictions
commit 338635340669d5b317c7e8dcf4fff4a0f3651d87 upstream.
alloc_pages_vma() may try to allocate THP page on the local NUMA node
first:
page = __alloc_pages_node(hpage_node,
gfp | __GFP_THISNODE | __GFP_NORETRY, order);
And if the allocation fails it retries allowing remote memory:
if (!page && (gfp & __GFP_DIRECT_RECLAIM))
page = __alloc_pages_node(hpage_node,
gfp, order);
However, this retry allocation completely ignores memory policy nodemask
allowing allocation to escape restrictions.
The first appearance of this bug seems to be the commit ac5b2c18911f
("mm: thp: relax __GFP_THISNODE for MADV_HUGEPAGE mappings").
The bug disappeared later in the commit 89c83fb539f9 ("mm, thp:
consolidate THP gfp handling into alloc_hugepage_direct_gfpmask") and
reappeared again in slightly different form in the commit 76e654cc91bb
("mm, page_alloc: allow hugepage fallback to remote nodes when
madvised")
Fix this by passing correct nodemask to the __alloc_pages() call.

usb: gadget: u_ether: fix race in setting MAC address in setup phase
commit 890d5b40908bfd1a79be018d2d297cf9df60f4ee upstream.
When listening for notifications through netlink of a new interface being
registered, sporadically, it is possible for the MAC to be read as zero.
The zero MAC address lasts a short period of time and then switches to a
valid random MAC address.
This causes problems for netd in Android, which assumes that the interface
is malfunctioning and will not use it.
In the good case we get this log:
InterfaceController::getCfg() ifName usb0
hwAddr 92:a8:f0:73:79:5b ipv4Addr 0.0.0.0 flags 0x1002
In the error case we get these logs:
InterfaceController::getCfg() ifName usb0
hwAddr 00:00:00:00:00:00 ipv4Addr 0.0.0.0 flags 0x1002
netd : interfaceGetCfg("usb0")
netd : interfaceSetCfg() -> ServiceSpecificException
(99, "[Cannot assign requested address] : ioctl() failed")
The reason for the issue is the order in which the interface is setup,
it is first registered through register_netdev() and after the MAC
address is set.
Fixed by first setting the MAC address of the net_device and after that
calling register_netdev().

ceph: fix up non-directory creation in SGID directories
commit fd84bfdddd169c219c3a637889a8b87f70a072c2 upstream.
Ceph always inherits the SGID bit if it is set on the parent inode,
while the generic inode_init_owner does not do this in a few cases where
it can create a possible security problem (cf. [1]).
Update ceph to strip the SGID bit just as inode_init_owner would.
This bug was detected by the mapped mount testsuite in [3]. The
testsuite tests all core VFS functionality and semantics with and
without mapped mounts. That is to say it functions as a generic VFS
testsuite in addition to a mapped mount testsuite. While working on
mapped mount support for ceph, SIGD inheritance was the only failing
test for ceph after the port.
The same bug was detected by the mapped mount testsuite in XFS in
January 2021 (cf. [2]).

commit 18549bf4b21c739a9def39f27dcac53e27286ab5 upstream.
Pointer to the allocated pages (struct page *page) has already
progressed towards the end of allocation. It is incorrect to perform
__free_pages(page, order) using this pointer as we would free any
arbitrary pages. Fix this by stop modifying the page pointer.

mm/hwpoison: clear MF_COUNT_INCREASED before retrying get_any_page()
commit 2a57d83c78f889bf3f54eede908d0643c40d5418 upstream.
Hulk Robot reported a panic in put_page_testzero() when testing
madvise() with MADV_SOFT_OFFLINE. The BUG() is triggered when retrying
get_any_page(). This is because we keep MF_COUNT_INCREASED flag in
second try but the refcnt is not increased.
page dumped because: VM_BUG_ON_PAGE(page_ref_count(page) == 0)

mmc: mmci: stm32: clear DLYB_CR after sending tuning command
commit ff31ee0a0f471776f67be5e5275c18d17736fc6b upstream.
During test campaign, and especially after several unbind/bind sequences,
it has been seen that the SD-card on SDMMC1 thread could freeze.
The freeze always appear on a CMD23 following a CMD19.
Checking SDMMC internal registers shows that the tuning command (CMD19)
has failed.
The freeze is then due to the delay block involved in the tuning sequence.
To correct this, clear the delay block register DLYB_CR register after
the tuning commands.

mmc: core: Disable card detect during shutdown
commit 66c915d09b942fb3b2b0cb2f56562180901fba17 upstream.
It's seems prone to problems by allowing card detect and its corresponding
mmc_rescan() work to run, during platform shutdown. For example, we may end
up turning off the power while initializing a card, which potentially could
damage it.
To avoid this scenario, let's add ->shutdown_pre() callback for the mmc host
class device and then turn of the card detect from there.

mmc: meson-mx-sdhc: Set MANUAL_STOP for multi-block SDIO commands
commit f89b548ca66be7500dcd92ee8e61590f7d08ac91 upstream.
The vendor driver implements special handling for multi-block
SD_IO_RW_EXTENDED (and SD_IO_RW_DIRECT) commands which have data
attached to them. It sets the MANUAL_STOP bit in the MESON_SDHC_MISC
register for these commands. In all other cases this bit is cleared.
Here we omit SD_IO_RW_DIRECT since that command never has any data
attached to it.
This fixes SDIO wifi using the brcmfmac driver which reported the
following error without this change on a Netxeon S82 board using a

When replugging the device the following message shows up:

This also has the effect that interrupts won't work.

Fix this by allocating the irq_chip data structure per instance like other

KVM: VMX: Wake vCPU when delivering posted IRQ even if vCPU == this vCPU
commit fdba608f15e2427419997b0898750a49a735afcb upstream.
Drop a check that guards triggering a posted interrupt on the currently
running vCPU, and more importantly guards waking the target vCPU if
triggering a posted interrupt fails because the vCPU isn't IN_GUEST_MODE.
If a vIRQ is delivered from asynchronous context, the target vCPU can be
the currently running vCPU and can also be blocking, in which case
skipping kvm_vcpu_wake_up() is effectively dropping what is supposed to
be a wake event for the vCPU.
The "do nothing" logic when "vcpu == running_vcpu" mostly works only
because the majority of calls to ->deliver_posted_interrupt(), especially
when using posted interrupts, come from synchronous KVM context. But if
a device is exposed to the guest using vfio-pci passthrough, the VFIO IRQ
and vCPU are bound to the same pCPU, and the IRQ is _not_ configured to
use posted interrupts, wake events from the device will be delivered to
KVM from IRQ context, e.g.
vfio_msihandler()
|
|-> eventfd_signal()
|
|-> ...
|
|-> irqfd_wakeup()
|
|->kvm_arch_set_irq_inatomic()
|
|-> kvm_irq_delivery_to_apic_fast()
|
|-> kvm_apic_set_irq()
This also aligns the non-nested and nested usage of triggering posted
interrupts, and will allow for additional cleanups.

Use unsigned constants instead.
Clearly pkey 15 has not been used in combination with UBSAN yet.

concerned.

tee: handle lookup of shm with reference count 0
commit dfd0743f1d9ea76931510ed150334d571fbab49d upstream.
Since the tee subsystem does not keep a strong reference to its idle
shared memory buffers, it races with other threads that try to destroy a
shared memory through a close of its dma-buf fd or by unmapping the
memory.
In tee_shm_get_from_id() when a lookup in teedev->idr has been
successful, it is possible that the tee_shm is in the dma-buf teardown
path, but that path is blocked by the teedev mutex. Since we don't have
an API to tell if the tee_shm is in the dma-buf teardown path or not we
must find another way of detecting this condition.
Fix this by doing the reference counting directly on the tee_shm using a
new refcount_t refcount field. dma-buf is replaced by using
anon_inode_getfd() instead, this separates the life-cycle of the
underlying file from the tee_shm. tee_shm_put() is updated to hold the
mutex when decreasing the refcount to 0 and then remove the tee_shm from
teedev->idr before releasing the mutex. This means that the tee_shm can
never be found unless it has a refcount larger than 0.

ASoC: meson: aiu: Move AIU_I2S_MISC hold setting to aiu-fifo-i2s
commit ee907afb0c39a41ee74b862882cfe12820c74b98 upstream.
The out-of-tree vendor driver uses the following approach to set the
AIU_I2S_MISC register:
1) write AIU_MEM_I2S_START_PTR and AIU_MEM_I2S_RD_PTR
2) configure AIU_I2S_MUTE_SWAP[15:0]
3) write AIU_MEM_I2S_END_PTR
4) set AIU_I2S_MISC[2] to 1 (documented as: "put I2S interface in hold
mode")
5) set AIU_I2S_MISC[4] to 1 (depending on the driver revision it always
stays at 1 while for older drivers this bit is unset in step 4)
6) set AIU_I2S_MISC[2] to 0
7) write AIU_MEM_I2S_MASKS
8) toggle AIU_MEM_I2S_CONTROL[0]
9) toggle AIU_MEM_I2S_BUF_CNTL[0]
Move setting the AIU_I2S_MISC[2] bit to aiu_fifo_i2s_hw_params() so it
resembles the flow in the vendor kernel more closely. While here also
configure AIU_I2S_MISC[4] (documented as: "force each audio data to
left or right according to the bit attached with the audio data")
similar to how the vendor driver does this. This fixes the infamous and
long-standing "machine gun noise" issue (a buffer underrun issue).

ALSA: hda/realtek: Fix quirk for Clevo NJ51CU
commit edca7cc4b0accfa69dc032442fe0684e59c691b8 upstream.
The Clevo NJ51CU comes either with the ALC293 or the ALC256 codec, but uses
the 0x8686 subproduct id in both cases. The ALC256 codec needs a different
quirk for the headset microphone working and and edditional quirk for sound
working after suspend and resume.
When waking up from s3 suspend the Coef 0x10 is set to 0x0220 instead of
0x0020 on the ALC256 codec. Setting the value manually makes the sound
work again. This patch does this automatically.

hwmon: (lm90) Add basic support for TI TMP461
[ Upstream commit f8344f7693a25d9025a59d164450b50c6f5aa3c0 ]
TMP461 is almost identical to TMP451 and was actually detected as TMP451
with the existing lm90 driver if its I2C address is 0x4c. Add support
for it to the lm90 driver. At the same time, improve the chip detection
function to at least try to distinguish between TMP451 and TMP461.
As a side effect, this fixes commit 24333ac26d01 ("hwmon: (tmp401) use
smb word operations instead of 2 smb byte operations"). TMP461 does not
support word operations on temperature registers, which causes bad
temperature readings with the tmp401 driver. The lm90 driver does not
perform word operations on temperature registers and thus does not have
this problem.
Support is listed as basic because TMP461 supports a sensor resolution
of 0.0625 degrees C, while the lm90 driver assumes a resolution of 0.125
degrees C. Also, the TMP461 supports negative temperatures with its
default temperature range, which is not the case for similar chips
supported by the lm90 and the tmp401 drivers. Those limitations will be
addressed with follow-up patches.

hwmon: (lm90) Fix usage of CONFIG2 register in detect function
[ Upstream commit fce15c45d3fbd9fc1feaaf3210d8e3f8b33dfd3a ]
The detect function had a comment "Make compiler happy" when id did not
read the second configuration register. As it turns out, the code was
checking the contents of this register for manufacturer ID 0xA1 (NXP
Semiconductor/Philips), but never actually read the register. So it
wasn't surprising that the compiler complained, and it indeed had a point.
Fix the code to read the register contents for manufacturer ID 0xa1.
At the same time, the code was reading the register for manufacturer ID
0x41 (Analog Devices), but it was not using the results. In effect it was
just checking if reading the register returned an error. That doesn't
really add much if any value, so stop doing that.

pinctrl: bcm2835: Change init order for gpio hogs
[ Upstream commit 266423e60ea1b953fcc0cd97f3dad85857e434d1 ]
...and gpio-ranges
pinctrl-bcm2835 is a combined pinctrl/gpio driver. Currently the gpio
side is registered first, but this breaks gpio hogs (which are
configured during gpiochip_add_data). Part of the hog initialisation
is a call to pinctrl_gpio_request, and since the pinctrl driver hasn't
yet been registered this results in an -EPROBE_DEFER from which it can
never recover.
Change the initialisation sequence to register the pinctrl driver
first.
This also solves a similar problem with the gpio-ranges property, which
is required in order for released pins to be returned to inputs.

The array param[] in elantech_change_report_id() must be at least 3
bytes, because elantech_read_reg_params() is calling ps2_command() with
PSMOUSE_CMD_GETINFO, that is going to access 3 bytes from param[], but
it's defined in the stack as an array of 2 bytes, therefore we have a
potential stack out-of-bounds access here, also confirmed by KASAN:

igb: fix deadlock caused by taking RTNL in RPM resume path
[ Upstream commit ac8c58f5b535d6272324e2b8b4a0454781c9147e ]
Recent net core changes caused an issue with few Intel drivers
(reportedly igb), where taking RTNL in RPM resume path results in a
deadlock. See [0] for a bug report. I don't think the core changes
are wrong, but taking RTNL in RPM resume path isn't needed.
The Intel drivers are the only ones doing this. See [1] for a
discussion on the issue. Following patch changes the RPM resume path
to not take RTNL.

net: skip virtio_net_hdr_set_proto if protocol already set
[ Upstream commit 1ed1d592113959f00cc552c3b9f47ca2d157768f ]
virtio_net_hdr_set_proto infers skb->protocol from the virtio_net_hdr
gso_type, to avoid packets getting dropped for lack of a proto type.
Its protocol choice is a guess, especially in the case of UFO, where
the single VIRTIO_NET_HDR_GSO_UDP label covers both UFOv4 and UFOv6.
Skip this best effort if the field is already initialized. Whether
explicitly from userspace, or implicitly based on an earlier call to
dev_parse_header_protocol (which is more robust, but was introduced
after this patch).

net: accept UFOv6 packages in virtio_net_hdr_to_skb
[ Upstream commit 7e5cced9ca84df52d874aca6b632f930b3dc5bc6 ]
Skb with skb->protocol 0 at the time of virtio_net_hdr_to_skb may have
a protocol inferred from virtio_net_hdr with virtio_net_hdr_set_proto.
Unlike TCP, UDP does not have separate types for IPv4 and IPv6. Type
VIRTIO_NET_HDR_GSO_UDP is guessed to be IPv4/UDP. As of the below
commit, UFOv6 packets are dropped due to not matching the protocol as
obtained from dev_parse_header_protocol.
Invert the test to take that L2 protocol field as starting point and
pass both UFOv4 and UFOv6 for VIRTIO_NET_HDR_GSO_UDP.

qlcnic: potential dereference null pointer of rx_queue->page_ring
[ Upstream commit 60ec7fcfe76892a1479afab51ff17a4281923156 ]
The return value of kcalloc() needs to be checked.
To avoid dereference of null pointer in case of the failure of alloc.
Therefore, it might be better to change the return type of
qlcnic_sriov_alloc_vlans() and return -ENOMEM when alloc fails and
return 0 the others.
Also, qlcnic_sriov_set_guest_vlan_mode() and __qlcnic_pci_sriov_enable()
should deal with the return value of qlcnic_sriov_alloc_vlans().

netfilter: fix regression in looped (broad|multi)cast's MAC handling
[ Upstream commit ebb966d3bdfed581ecccbb4a7432341baf7619b4 ]
In commit 5648b5e1169f ("netfilter: nfnetlink_queue: fix OOB when mac
header was cleared"), the test for non-empty MAC header introduced in
commit 2c38de4c1f8da7 ("netfilter: fix looped (broad|multi)cast's MAC
handling") has been replaced with a test for a set MAC header.
This breaks the case when the MAC header has been reset (using
skb_reset_mac_header), as is the case with looped-back multicast
packets. As a result, the packets ending up in NFQUEUE get a bogus
hwaddr interpreted from the first bytes of the IP header.
This patch adds a test for a non-empty MAC header in addition to the
test for a set MAC header. The same two tests are also implemented in
nfnetlink_log.c, where the initial code of commit 2c38de4c1f8da7
("netfilter: fix looped (broad|multi)cast's MAC handling") has not been
touched, but where supposedly the same situation may happen.

ext4: prevent partial update of the extent blocks
commit 0f2f87d51aebcf71a709b52f661d681594c7dffa upstream.
In the most error path of current extents updating operations are not
roll back partial updates properly when some bad things happens(.e.g in
ext4_ext_insert_extent()). So we may get an inconsistent extents tree
if journal has been aborted due to IO error, which may probability lead
to BUGON later when we accessing these extent entries in errors=continue
mode. This patch drop extent buffer's verify flag before updatng the
contents in ext4_ext_get_access(), and reset it after updating in
__ext4_ext_dirty(). After this patch we could force to check the extent
buffer if extents tree updating was break off, make sure the extents are
consistent.
