Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: remove device from smcd_dev_list after failed device_add()
If the device_add() for a smcd_dev fails, there's no cleanup step that
rolls back the earlier list_add(). The device subsequently gets freed,
and we end up with a corrupted list.
Add some error handling that removes the device from the list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: fec: fix the potential memory leak in fec_enet_init()
If the memory allocated for cbd_base is failed, it should
free the memory allocated for the queues, otherwise it causes
memory leak.
And if the memory allocated for the queues is failed, it can
return error directly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: adc: ad7124: Fix potential overflow due to non sequential channel numbers
Channel numbering must start at 0 and then not have any holes, or
it is possible to overflow the available storage. Note this bug was
introduced as part of a fix to ensure we didn't rely on the ordering
of child nodes. So we need to support arbitrary ordering but they all
need to be there somewhere.
Note I hit this when using qemu to test the rest of this series.
Arguably this isn't the best fix, but it is probably the most minimal
option for backporting etc.
Alexandru's sign-off is here because he carried this patch in a larger
set that Jonathan then applied.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mptcp: fix data stream corruption
Maxim reported several issues when forcing a TCP transparent proxy
to use the MPTCP protocol for the inbound connections. He also
provided a clean reproducer.
The problem boils down to 'mptcp_frag_can_collapse_to()' assuming
that only MPTCP will use the given page_frag.
If others - e.g. the plain TCP protocol - allocate page fragments,
we can end-up re-using already allocated memory for mptcp_data_frag.
Fix the issue ensuring that the to-be-expanded data fragment is
located at the current page frag end.
v1 -> v2:
- added missing fixes tag (Mat)

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/amd: Clear DMA ops when switching domain
Since commit 08a27c1c3ecf ("iommu: Add support to change default domain
of an iommu group") a user can switch a device between IOMMU and direct
DMA through sysfs. This doesn't work for AMD IOMMU at the moment because
dev->dma_ops is not cleared when switching from a DMA to an identity
IOMMU domain. The DMA layer thus attempts to use the dma-iommu ops on an
identity domain, causing an oops:
# echo 0000:00:05.0 > /sys/sys/bus/pci/drivers/e1000e/unbind
# echo identity > /sys/bus/pci/devices/0000:00:05.0/iommu_group/type
# echo 0000:00:05.0 > /sys/sys/bus/pci/drivers/e1000e/bind
...
BUG: kernel NULL pointer dereference, address: 0000000000000028
...
Call Trace:
iommu_dma_alloc
e1000e_setup_tx_resources
e1000e_open
Since iommu_change_dev_def_domain() calls probe_finalize() again, clear
the dma_ops there like Vt-d does.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i2c: i801: Don't generate an interrupt on bus reset
Now that the i2c-i801 driver supports interrupts, setting the KILL bit
in a attempt to recover from a timed out transaction triggers an
interrupt. Unfortunately, the interrupt handler (i801_isr) is not
prepared for this situation and will try to process the interrupt as
if it was signaling the end of a successful transaction. In the case
of a block transaction, this can result in an out-of-range memory
access.
This condition was reproduced several times by syzbot:
https://syzkaller.appspot.com/bug?extid=ed71512d469895b5b34e
https://syzkaller.appspot.com/bug?extid=8c8dedc0ba9e03f6c79e
https://syzkaller.appspot.com/bug?extid=c8ff0b6d6c73d81b610e
https://syzkaller.appspot.com/bug?extid=33f6c360821c399d69eb
https://syzkaller.appspot.com/bug?extid=be15dc0b1933f04b043a
https://syzkaller.appspot.com/bug?extid=b4d3fd1dfd53e90afd79
So disable interrupts while trying to reset the bus. Interrupts will
be enabled again for the following transaction.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: mt7530: fix VLAN traffic leaks
PCR_MATRIX field was set to all 1's when VLAN filtering is enabled, but
was not reset when it is disabled, which may cause traffic leaks:
ip link add br0 type bridge vlan_filtering 1
ip link add br1 type bridge vlan_filtering 1
ip link set swp0 master br0
ip link set swp1 master br1
ip link set br0 type bridge vlan_filtering 0
ip link set br1 type bridge vlan_filtering 0
# traffic in br0 and br1 will start leaking to each other
As port_bridge_{add,del} have set up PCR_MATRIX properly, remove the
PCR_MATRIX write from mt7530_port_set_vlan_aware.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: fix a crash if ->get_sset_count() fails
If ds->ops->get_sset_count() fails then it "count" is a negative error
code such as -EOPNOTSUPP. Because "i" is an unsigned int, the negative
error code is type promoted to a very high value and the loop will
corrupt memory until the system crashes.
Fix this by checking for error codes and changing the type of "i" to
just int.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tipc: skb_linearize the head skb when reassembling msgs
It's not a good idea to append the frag skb to a skb's frag_list if
the frag_list already has skbs from elsewhere, such as this skb was
created by pskb_copy() where the frag_list was cloned (all the skbs
in it were skb_get'ed) and shared by multiple skbs.
However, the new appended frag skb should have been only seen by the
current skb. Otherwise, it will cause use after free crashes as this
appended frag skb are seen by multiple skbs but it only got skb_get
called once.
The same thing happens with a skb updated by pskb_may_pull() with a
skb_cloned skb. Li Shuang has reported quite a few crashes caused
by this when doing testing over macvlan devices:

...
This patch is to fix it by linearizing the head skb if it has frag_list
set in tipc_buf_append(). Note that we choose to do this before calling
skb_unshare(), as __skb_linearize() will avoid skb_copy(). Also, we can
not just drop the frag_list either as the early time.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cxgb4: avoid accessing registers when clearing filters
Hardware register having the server TID base can contain
invalid values when adapter is in bad state (for example,
due to AER fatal error). Reading these invalid values in the
register can lead to out-of-bound memory access. So, fix
by using the saved server TID base when clearing filters.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mld: fix panic in mld_newpack()
mld_newpack() doesn't allow to allocate high order page,
only order-0 allocation is allowed.
If headroom size is too large, a kernel panic could occur in skb_put().
Test commands:
ip netns del A
ip netns del B
ip netns add A
ip netns add B
ip link add veth0 type veth peer name veth1
ip link set veth0 netns A
ip link set veth1 netns B
ip netns exec A ip link set lo up
ip netns exec A ip link set veth0 up
ip netns exec A ip -6 a a 2001:db8:0::1/64 dev veth0
ip netns exec B ip link set lo up
ip netns exec B ip link set veth1 up
ip netns exec B ip -6 a a 2001:db8:0::2/64 dev veth1
for i in {1..99}
do
let A=$i-1
ip netns exec A ip link add ip6gre$i type ip6gre \
local 2001:db8:$A::1 remote 2001:db8:$A::2 encaplimit 100
ip netns exec A ip -6 a a 2001:db8:$i::1/64 dev ip6gre$i
ip netns exec A ip link set ip6gre$i up
ip netns exec B ip link add ip6gre$i type ip6gre \
local 2001:db8:$A::2 remote 2001:db8:$A::1 encaplimit 100
ip netns exec B ip -6 a a 2001:db8:$i::2/64 dev ip6gre$i
ip netns exec B ip link set ip6gre$i up
done
Splat looks like:

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: core: Avoid smp_processor_id() in preemptible code
The BUG message "BUG: using smp_processor_id() in preemptible [00000000]
code" was observed for TCMU devices with kernel config DEBUG_PREEMPT.
The message was observed when blktests block/005 was run on TCMU devices
with fileio backend or user:zbc backend [1]. The commit 1130b499b4a7
("scsi: target: tcm_loop: Use LIO wq cmd submission helper") triggered the
symptom. The commit modified work queue to handle commands and changed
'current->nr_cpu_allowed' at smp_processor_id() call.
The message was also observed at system shutdown when TCMU devices were not
cleaned up [2]. The function smp_processor_id() was called in SCSI host
work queue for abort handling, and triggered the BUG message. This symptom
was observed regardless of the commit 1130b499b4a7 ("scsi: target:
tcm_loop: Use LIO wq cmd submission helper").
To avoid the preemptible code check at smp_processor_id(), get CPU ID with
raw_smp_processor_id() instead. The CPU ID is used for performance
improvement then thread move to other CPU will not affect the code.

The CPU ID is used for performance\nimprovement then thread move to other CPU will not affect the code.\n\n[1]\n\n[ 56.468103] run blktests block/005 at 2021-05-12 14:16:38\n[ 57.369473] check_preemption_disabled: 85 callbacks suppressed\n[ 57.369480] BUG: using smp_processor_id() in preemptible [00000000] code: fio/1511\n[ 57.369506] BUG: using smp_processor_id() in preemptible [00000000] code: fio/1510\n[ 57.369512] BUG: using smp_processor_id() in preemptible [00000000] code: fio/1506\n[ 57.369552] caller is __target_init_cmd+0x157/0x170 [target_core_mod]\n[ 57.369606] CPU: 4 PID: 1506 Comm: fio Not tainted 5.13.0-rc1+ #34\n[ 57.369613] Hardware name: System manufacturer System Product Name/PRIME Z270-A, BIOS 1302 03/15/2018\n[ 57.369617] Call Trace:\n[ 57.369621] BUG: using smp_processor_id() in preemptible [00000000] code: fio/1507\n[ 57.369628] dump_stack+0x6d/0x89\n[ 57.369642] check_preemption_disabled+0xc8/0xd0\n[ 57.369628] caller is __target_init_cmd+0x157/0x170 [target_core_mod]\n[ 57.369655] __target_init_cmd+0x157/0x170 [target_core_mod]\n[ 57.369695] target_init_cmd+0x76/0x90 [target_core_mod]\n[ 57.369732] tcm_loop_queuecommand+0x109/0x210 [tcm_loop]\n[ 57.369744] scsi_queue_rq+0x38e/0xc40\n[ 57.369761] __blk_mq_try_issue_directly+0x109/0x1c0\n[ 57.369779] blk_mq_try_issue_directly+0x43/0x90\n[ 57.369790] blk_mq_submit_bio+0x4e5/0x5d0\n[ 57.369812] submit_bio_noacct+0x46e/0x4e0\n[ 57.369830] __blkdev_direct_IO_simple+0x1a3/0x2d0\n[ 57.369859] ? set_init_blocksize.isra.0+0x60/0x60\n[ 57.369880] generic_file_read_iter+0x89/0x160\n[ 57.369898] blkdev_read_iter+0x44/0x60\n[ 57.369906] new_sync_read+0x102/0x170\n[ 57.369929] vfs_read+0xd4/0x160\n[ 57.369941] __x64_sys_pread64+0x6e/0xa0\n[ 57.369946] ? lockdep_hardirqs_on+0x79/0x100\n[ 57.369958] do_syscall_64+0x3a/0x70\n[ 57.369965] entry_SYSCALL_64_after_hwframe+0x44/0xae\n[ 57.369973] RIP: 0033:0x7f7ed4c1399f\n[ 57.369979] Code: 08 89 3c 24 48 89 4c 24 18 e8 7d f3 ff ff 4c 8b 54 24 18 48 8b 54 24 10 41 89 c0 48 8b 74 24 08 8b 3c 24 b8 11 00 00 00 0f 05 \u003c48\u003e 3d 00 f0 ff ff 77 31 44 89 c7 48 89 04 24 e8 cd f3 ff ff 48 8b\n[ 57.369983] RSP: 002b:00007ffd7918c580 EFLAGS: 00000293 ORIG_RAX: 0000000000000011\n[ 57.369990] RAX: ffffffffffffffda RBX: 00000000015b4540 RCX: 00007f7ed4c1399f\n[ 57.369993] RDX: 0000000000001000 RSI: 00000000015de000 RDI: 0000000000000009\n[ 57.369996] RBP: 00000000015b4540 R08: 0000000000000000 R09: 0000000000000001\n[ 57.369999] R10: 0000000000e5c000 R11: 0000000000000293 R12: 00007f7eb5269a70\n[ 57.370002] R13: 0000000000000000 R14: 0000000000001000 R15: 00000000015b4568\n[ 57.370031] CPU: 7 PID: 1507 Comm: fio Not tainted 5.13.0-rc1+ #34\n[ 57.370036] Hardware name: System manufacturer System Product Name/PRIME Z270-A, BIOS 1302 03/15/2018\n[ 57.370039] Call Trace:\n[ 57.370045] dump_stack+0x6d/0x89\n[ 57.370056] ch\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/dasd: add missing discipline function
Fix crash with illegal operation exception in dasd_device_tasklet.
Commit b72949328869 ("s390/dasd: Prepare for additional path event handling")
renamed the verify_path function for ECKD but not for FBA and DIAG.
This leads to a panic when the path verification function is called for a
FBA or DIAG device.
Fix by defining a wrapper function for dasd_generic_verify_path().

Summary
In the Linux kernel, the following vulnerability has been resolved:
tipc: wait and exit until all work queues are done
On some host, a crash could be triggered simply by repeating these
commands several times:
# modprobe tipc
# tipc bearer enable media udp name UDP1 localip 127.0.0.1
# rmmod tipc
[] BUG: unable to handle kernel paging request at ffffffffc096bb00
[] Workqueue: events 0xffffffffc096bb00
[] Call Trace:
[] ? process_one_work+0x1a7/0x360
[] ? worker_thread+0x30/0x390
[] ? create_worker+0x1a0/0x1a0
[] ? kthread+0x116/0x130
[] ? kthread_flush_work_fn+0x10/0x10
[] ? ret_from_fork+0x35/0x40
When removing the TIPC module, the UDP tunnel sock will be delayed to
release in a work queue as sock_release() can't be done in rtnl_lock().
If the work queue is schedule to run after the TIPC module is removed,
kernel will crash as the work queue function cleanup_beareri() code no
longer exists when trying to invoke it.
To fix it, this patch introduce a member wq_count in tipc_net to track
the numbers of work queues in schedule, and wait and exit until all
work queues are done in tipc_exit_net().

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: sja1105: add error handling in sja1105_setup()
If any of sja1105_static_config_load(), sja1105_clocking_setup() or
sja1105_devlink_setup() fails, we can't just return in the middle of
sja1105_setup() or memory will leak. Add a cleanup path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gve: Add NULL pointer checks when freeing irqs.
When freeing notification blocks, we index priv->msix_vectors.
If we failed to allocate priv->msix_vectors (see abort_with_msix_vectors)
this could lead to a NULL pointer dereference if the driver is unloaded.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: zero-initialize tc skb extension on allocation
Function skb_ext_add() doesn't initialize created skb extension with any
value and leaves it up to the user. However, since extension of type
TC_SKB_EXT originally contained only single value tc_skb_ext->chain its
users used to just assign the chain value without setting whole extension
memory to zero first. This assumption changed when TC_SKB_EXT extension was
extended with additional fields but not all users were updated to
initialize the new fields which leads to use of uninitialized memory
afterwards. UBSAN log:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Fix null deref accessing lag dev
It could be the lag dev is null so stop processing the event.
In bond_enslave() the active/backup slave being set before setting the
upper dev so first event is without an upper dev.
After setting the upper dev with bond_master_upper_dev_link() there is
a second event and in that event we have an upper dev.

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: rp2: use 'request_firmware' instead of 'request_firmware_nowait'
In 'rp2_probe', the driver registers 'rp2_uart_interrupt' then calls
'rp2_fw_cb' through 'request_firmware_nowait'. In 'rp2_fw_cb', if the
firmware don't exists, function just return without initializing ports
of 'rp2_card'. But now the interrupt handler function has been
registered, and when an interrupt comes, 'rp2_uart_interrupt' may access
those ports then causing NULL pointer dereference or other bugs.
Because the driver does some initialization work in 'rp2_fw_cb', in
order to make the driver ready to handle interrupts, 'request_firmware'
should be used instead of asynchronous 'request_firmware_nowait'.
This report reveals it:
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4: Fix a NULL pointer dereference in pnfs_mark_matching_lsegs_return()
Commit de144ff4234f changes _pnfs_return_layout() to call
pnfs_mark_matching_lsegs_return() passing NULL as the struct
pnfs_layout_range argument. Unfortunately,
pnfs_mark_matching_lsegs_return() doesn't check if we have a value here
before dereferencing it, causing an oops.
I'm able to hit this crash consistently when running connectathon basic
tests on NFS v4.1/v4.2 against Ontap.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFS: fix an incorrect limit in filelayout_decode_layout()
The "sizeof(struct nfs_fh)" is two bytes too large and could lead to
memory corruption. It should be NFS_MAXFHSIZE because that's the size
of the ->data[] buffer.
I reversed the size of the arguments to put the variable on the left.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: lantiq: fix memory corruption in RX ring
In a situation where memory allocation or dma mapping fails, an
invalid address is programmed into the descriptor. This can lead
to memory corruption. If the memory allocation fails, DMA should
reuse the previous skb and mapping and drop the packet. This patch
also increments rx drop counter.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: put off calling register_netdev() until client initialize complete
Currently, the netdevice is registered before client initializing
complete. So there is a timewindow between netdevice available
and usable. In this case, if user try to change the channel number
or ring param, it may cause the hns3_set_rx_cpu_rmap() being called
twice, and report bug.

The process is like below:
excuting hns3_client_init
|
register_netdev()
| hns3_set_channels()
| |
hns3_set_rx_cpu_rmap() hns3_reset_notify_uninit_enet()
| |
| quit without calling function
| hns3_free_rx_cpu_rmap for flag
| HNS3_NIC_STATE_INITED is unset.
| |
| hns3_reset_notify_init_enet()
| |
set HNS3_NIC_STATE_INITED call hns3_set_rx_cpu_rmap()-- crash
Fix it by calling register_netdev() at the end of function
hns3_client_init().

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFS: Fix an Oopsable condition in __nfs_pageio_add_request()
Ensure that nfs_pageio_error_cleanup() resets the mirror array contents,
so that the structure reflects the fact that it is now empty.
Also change the test in nfs_pageio_do_add_request() to be more robust by
checking whether or not the list is empty rather than relying on the
value of pg_count.

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: usbfs: Don't WARN about excessively large memory allocations
Syzbot found that the kernel generates a WARNing if the user tries to
submit a bulk transfer through usbfs with a buffer that is way too
large. This isn't a bug in the kernel; it's merely an invalid request
from the user and the usbfs code does handle it correctly.
In theory the same thing can happen with async transfers, or with the
packet descriptor table for isochronous transfers.
To prevent the MM subsystem from complaining about these bad
allocation requests, add the __GFP_NOWARN flag to the kmalloc calls
for these buffers.
