virtio_net_hdr_to_skb does not set the skb's gso_size and gso_type
correctly for UFO packets received via virtio-net that are a little over
the GSO size. This can lead to problems elsewhere in the networking
stack, e.g. ovs_vport_send dropping over-sized packets if gso_size is
not set.
This is due to the comparison
if (skb->len - p_off > gso_size)
not properly accounting for the transport layer header.
p_off includes the size of the transport layer header (thlen), so
skb->len - p_off is the size of the TCP/UDP payload.
gso_size is read from the virtio-net header. For UFO, fragmentation
happens at the IP level so does not need to include the UDP header.
Hence the calculation could be comparing a TCP/UDP payload length with
an IP payload length, causing legitimate virtio-net packets to have
lack gso_type/gso_size information.
Example: a UDP packet with payload size 1473 has IP payload size 1481.
If the guest used UFO, it is not fragmented and the virtio-net header's
flags indicate that it is a GSO frame (VIRTIO_NET_HDR_GSO_UDP), with
gso_size = 1480 for an MTU of 1500. skb->len will be 1515 and p_off
will be 42, so skb->len - p_off = 1473. Hence the comparison fails, and
shinfo->gso_size and gso_type are not set as they should be.
Instead, add the UDP header length before comparing to gso_size when
using UFO. In this way, it is the size of the IP payload that is
compared to gso_size.

E-Switch encap mode is relevant only when in switchdev mode.
The RDMA driver can query the encap configuration via
mlx5_eswitch_get_encap_mode(). Make sure it returns the currently
used mode and not the set one.
This reverts the cited commit which reset the encap mode
on entering switchdev and fixes the original issue properly.

Commit a23740ec43 ("bpf: Track contents of read-only maps as scalars") is
checking whether maps are read-only both from BPF program side and user space
side, and then, given their content is constant, reading out their data via
map->ops->map_direct_value_addr() which is then subsequently used as known
scalar value for the register, that is, it is marked as __mark_reg_known()
with the read value at verification time. Before a23740ec43, the register
content was marked as an unknown scalar so the verifier could not make any
assumptions about the map content.
The current implementation however is prone to a TOCTOU race, meaning, the
value read as known scalar for the register is not guaranteed to be exactly
the same at a later point when the program is executed, and as such, the
prior made assumptions of the verifier with regards to the program will be
invalid which can cause issues such as OOB access, etc.
While the BPF_F_RDONLY_PROG map flag is always fixed and required to be
specified at map creation time, the map->frozen property is initially set to
false for the map given the map value needs to be populated, e.g. for global
data sections. Once complete, the loader "freezes" the map from user space
such that no subsequent updates/deletes are possible anymore. For the rest
of the lifetime of the map, this freeze one-time trigger cannot be undone
anymore after a successful BPF_MAP_FREEZE cmd return. Meaning, any new BPF_*
cmd calls which would update/delete map entries will be rejected with -EPERM
since map_get_sys_perms() removes the FMODE_CAN_WRITE permission. This also
means that pending update/delete map entries must still complete before this
guarantee is given. This corner case is not an issue for loaders since they
create and prepare such program private map in successive steps.
However, a malicious user is able to trigger this TOCTOU race in two different
ways: i) via userfaultfd, and ii) via batched updates. For i) userfaultfd is
used to expand the competition interval, so that map_update_elem() can modify
the contents of the map after map_freeze() and bpf_prog_load() were executed.
This works, because userfaultfd halts the parallel thread which triggered a
map_update_elem() at the time where we copy key/value from the user buffer and
this already passed the FMODE_CAN_WRITE capability test given at that time the
map was not "frozen". Then, the main thread performs the map_freeze() and
bpf_prog_load(), and once that had completed successfully, the other thread
is woken up to complete the pending map_update_elem() which then changes the
map content. For ii) the idea of the batched update is similar, meaning, when
there are a large number of updates to be processed, it can increase the
competition interval between the two. It is therefore possible in practice to
modify the contents of the map after executing map_freeze() and bpf_prog_load().
One way to fix both i) and ii) at the same time is to expand the use of the
map's map->writecnt. The latter was introduced in fc9702273e ("bpf: Add mmap()
support for BPF_MAP_TYPE_ARRAY") and further refined in 1f6cb19be2 ("bpf:
Prevent re-mmap()'ing BPF map as writable for initially r/o mapping") with
the rationale to make a writable mmap()'ing of a map mutually exclusive with
read-only freezing. The counter indicates writable mmap() mappings and then
prevents/fails the freeze operation. Its semantics can be expanded beyond
just mmap() by generally indicating ongoing write phases. This would essentially
span any parallel regular and batched flavor of update/delete operation and
then also have map_freeze() fail with -EBUSY. For the check_mem_access() in
the verifier we expand upon the bpf_map_is_rdonly() check ensuring that all
last pending writes have completed via bpf_map_write_active() test. Once the
map->frozen is set and bpf_map_write_active() indicates a map->writecnt of 0
only then we are really guaranteed to use the map's data as known constants.
For map->frozen being set and pending writes in process of still being completed
we fall back to marking that register as unknown scalar so we don't end up
making assumptions about it. With this, both TOCTOU reproducers from i) and
ii) are fixed.
Note that the map->writecnt has been converted into a atomic64 in the fix in
order to avoid a double freeze_mutex mutex_{un,}lock() pair when updating
map->writecnt in the various map update/delete BPF_* cmd flavors. Spanning
the freeze_mutex over entire map update/delete operations in syscall side
would not be possible due to then causing everything to be serialized.
Similarly, something like synchronize_rcu() after setting map->frozen to wait
for update/deletes to complete is not possible either since it would also
have to span the user copy which can sleep. On the libbpf side, this won't
break d66562fba1 ("libbpf: Add BPF object skeleton support") as the
anonymous mmap()-ed "map initialization image" is remapped as a BPF map-backed
mmap()-ed memory where for .rodata it's non-writable.

This patch reverts two prior patches, e7310c9402
("security: implement sctp_assoc_established hook in selinux") and
7c2ef0240e ("security: add sctp_assoc_established hook"), which
create the security_sctp_assoc_established() LSM hook and provide a
SELinux implementation. Unfortunately these two patches were merged
without proper review (the Reviewed-by and Tested-by tags from
Richard Haines were for previous revisions of these patches that
were significantly different) and there are outstanding objections
from the SELinux maintainers regarding these patches.
Work is currently ongoing to correct the problems identified in the
reverted patches, as well as others that have come up during review,
but it is unclear at this point in time when that work will be ready
for inclusion in the mainline kernel. In the interest of not keeping
objectionable code in the kernel for multiple weeks, and potentially
a kernel release, we are reverting the two problematic patches.

Pull PCI fixes from Bjorn Helgaas:
"Revert conversion to struct device.driver instead of struct
pci_dev.driver.
The device.driver is set earlier, and using it caused the PCI core to
call driver PM entry points before .probe() and after .remove(), when
the driver isn't prepared.
This caused NULL pointer dereferences in i2c_designware_pci and
probably other driver issues"
* tag 'pci-v5.16-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci:
Revert "PCI: Use to_pci_driver() instead of pci_dev->driver"
Revert "PCI: Remove struct pci_dev->driver"
ACS-3 introduced the ATA Identify Device Data log as mandatory. A
warning message currently signals to the user if a device does not
report supporting this log page in the log directory page, regardless
of the ATA version of the device. Furthermore, this warning will appear
for all attempts at accessing this missing log page during device
revalidation.
Since it is useless to constantly access the log directory and warn
about this lack of support once we have discovered that the device
does not support this log page, introduce the horkage flag
ATA_HORKAGE_NO_ID_DEV_LOG to mark a device as lacking support for
the Identify Device Data log page. Set this flag when
ata_log_supported() returns false in ata_identify_page_supported().
The warning is printed only if the device ATA level is 10 or above
(ACS-3 or above), and only once on device scan. With this flag set, the
log directory page is not accessed again to test for Identify Device
Data log page support.

MIGRATE_PFN_LOCKED is used to indicate to migrate_vma_prepare() that a
source page was already locked during migrate_vma_collect(). If it
wasn't then the a second attempt is made to lock the page. However if
the first attempt failed it's unlikely a second attempt will succeed,
and the retry adds complexity. So clean this up by removing the retry
and MIGRATE_PFN_LOCKED flag.
Destination pages are also meant to have the MIGRATE_PFN_LOCKED flag
set, but nothing actually checks that.

The type of "order" in struct page_owner is unsigned short.
However, it is unsigned int in the following 3 functions:
__reset_page_owner
__set_page_owner_handle
__set_page_owner_handle
The type of "order" in argument list is unsigned int, which is
inconsistent.

Some ATA drives are very slow to respond to READ_LOG_EXT and
READ_LOG_DMA_EXT commands issued from ata_dev_configure() when the
device is revalidated right after resuming a system or inserting the
ATA adapter driver (e.g. ahci). The default 5s timeout
(ATA_EH_CMD_DFL_TIMEOUT) used for these commands is too short, causing
errors during the device configuration. Ex:
...
ata9: SATA max UDMA/133 abar m524288@0x9d200000 port 0x9d200400 irq 209
ata9: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
ata9.00: ATA-9: XXX XXXXXXXXXXXXXXX, XXXXXXXX, max UDMA/133
ata9.00: qc timeout (cmd 0x2f)
ata9.00: Read log page 0x00 failed, Emask 0x4
ata9.00: Read log page 0x00 failed, Emask 0x40
ata9.00: NCQ Send/Recv Log not supported
ata9.00: Read log page 0x08 failed, Emask 0x40
ata9.00: 27344764928 sectors, multi 16: LBA48 NCQ (depth 32), AA
ata9.00: Read log page 0x00 failed, Emask 0x40
ata9.00: ATA Identify Device Log not supported
ata9.00: failed to set xfermode (err_mask=0x40)
ata9: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
ata9.00: configured for UDMA/133
...
The timeout error causes a soft reset of the drive link, followed in
most cases by a successful revalidation as that give enough time to the
drive to become fully ready to quickly process the read log commands.
However, in some cases, this also fails resulting in the device being
dropped.
Fix this by using adding the ata_eh_revalidate_timeouts entries for the
READ_LOG_EXT and READ_LOG_DMA_EXT commands. This defines a timeout
increased to 15s, retriable one time.

Pull exit cleanups from Eric Biederman:
"While looking at some issues related to the exit path in the kernel I
found several instances where the code is not using the existing
abstractions properly.
This set of changes introduces force_fatal_sig a way of sending a
signal and not allowing it to be caught, and corrects the misuse of
the existing abstractions that I found.
A lot of the misuse of the existing abstractions are silly things such
as doing something after calling a no return function, rolling BUG by
hand, doing more work than necessary to terminate a kernel thread, or
calling do_exit(SIGKILL) instead of calling force_sig(SIGKILL).
In the review a deficiency in force_fatal_sig and force_sig_seccomp
where ptrace or sigaction could prevent the delivery of the signal was
found. I have added a change that adds SA_IMMUTABLE to change that
makes it impossible to interrupt the delivery of those signals, and
allows backporting to fix force_sig_seccomp
And Arnd found an issue where a function passed to kthread_run had the
wrong prototype, and after my cleanup was failing to build."

Pull prctl updates from Christian Brauner:
"This contains the missing prctl uapi pieces for PR_SCHED_CORE.
In order to activate core scheduling the caller is expected to specify
the scope of the new core scheduling domain.
For example, passing 2 in the 4th argument of
prctl(PR_SCHED_CORE, PR_SCHED_CORE_CREATE, <pid>, 2, 0);
would indicate that the new core scheduling domain encompasses all
tasks in the process group of <pid>. Specifying 0 would only create a
core scheduling domain for the thread identified by <pid> and 2 would
encompass the whole thread-group of <pid>.
Note, the values 0, 1, and 2 correspond to PIDTYPE_PID, PIDTYPE_TGID,
and PIDTYPE_PGID. A first version tried to expose those values
directly to which I objected because:
- PIDTYPE_* is an enum that is kernel internal which we should not
expose to userspace directly.
- PIDTYPE_* indicates what a given struct pid is used for it doesn't
express a scope.
But what the 4th argument of PR_SCHED_CORE prctl() expresses is the
scope of the operation, i.e. the scope of the core scheduling domain
at creation time. So Eugene's patch now simply introduces three new
defines PR_SCHED_CORE_SCOPE_THREAD, PR_SCHED_CORE_SCOPE_THREAD_GROUP,
and PR_SCHED_CORE_SCOPE_PROCESS_GROUP. They simply express what
happens.
This has been on the mailing list for quite a while with all relevant
scheduler folks Cced. I announced multiple times that I'd pick this up
if I don't see or her anyone else doing it. None of this touches
proper scheduler code but only concerns uapi so I think this is fine.
With core scheduling being quite common now for vm managers (e.g.
moving individual vcpu threads into their own core scheduling domain)
and container managers (e.g. moving the init process into its own core
scheduling domain and letting all created children inherit it) having
to rely on raw numbers passed as the 4th argument in prctl() is a bit
annoying and everyone is starting to come up with their own defines"

Pull pidfd updates from Christian Brauner:
"Various places in the kernel have picked up pidfds.
The two most recent additions have probably been the ability to use
pidfds in bpf maps and the usage of pidfds in mm-based syscalls such
as process_mrelease() and process_madvise().
The same pattern to turn a pidfd into a struct task exists in two
places. One of those places used PIDTYPE_TGID while the other one used
PIDTYPE_PID even though it is clearly documented in all pidfd-helpers
that pidfds __currently__ only refer to thread-group leaders (subject
to change in the future if need be).
This isn't a bug per se but has the potential to be one if we allow
pidfds to refer to individual threads. If that happens we want to
audit all codepaths that make use of them to ensure they can deal with
pidfds refering to individual threads.
This adds a simple helper to turn a pidfd into a struct task making it
easy to grep for such places. Plus, it gets rid of code-duplication"

Pull more ACPI updates from Rafael Wysocki:
"These add support for a new ACPI device configuration object called
_DSC, fix some issues including one recent regression, add two new
items to quirk lists and clean up assorted pieces of code.
Specifics:
- Add support for new ACPI device configuration object called _DSC
("Deepest State for Configuration") to allow certain devices to be
probed without changing their power states, document it and make
two drivers use it (Sakari Ailus, Rajmohan Mani).
- Fix device wakeup power reference counting broken recently by
mistake (Rafael Wysocki).
- Drop unused symbol and macros depending on it from acgcc.h (Rafael
Wysocki).
- Add HP ZHAN 66 Pro to the "no EC wakeup" quirk list (Binbin Zhou).
- Add Xiaomi Mi Pad 2 to the backlight quirk list and drop an unused
piece of data from all of the list entries (Hans de Goede).
- Fix register read accesses handling in the Intel PMIC operation
region driver (Hans de Goede).
- Clean up static variables initialization in the EC driver
(wangzhitong)"

The Qualcomm modem and TrustZone based remoteproc drivers gains support
for the modem in SC7280 and MSM8996 gains support for a missing

Throughout the Qualcomm drivers, the support for informing the always-on
power coprocessor about the state of each remoteproc is reworked to

state.
Lastly a number of small fixes are found throughout the drivers and

For the GLINK implementation this adds support for splitting outgoing

"read notifications", to avoid polling in the case where the outgoing
fifo is full and a few bugs are squashed.
The return value of rpmsg_create_ept() for when RPMSG is disabled is
corrected to return a valid error, the Mediatek rpmsg driver is updated
to match the DT binding and a couple of cleanups are done in the virtio
rpmsg driver.

Merge tag 'rpmsg-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux
Pull rpmsg updates from Bjorn Andersson:
"For the GLINK implementation this adds support for splitting outgoing
messages that are too large to fit in the fifo, it introduces the use
of "read notifications", to avoid polling in the case where the
outgoing fifo is full and a few bugs are squashed.
The return value of rpmsg_create_ept() for when RPMSG is disabled is
corrected to return a valid error, the Mediatek rpmsg driver is
updated to match the DT binding and a couple of cleanups are done in
the virtio rpmsg driver"
