kern_select() normalises the user-supplied struct __kernel_old_timeval
with
tv.tv_sec + (tv.tv_usec / USEC_PER_SEC)
(tv.tv_usec % USEC_PER_SEC) * NSEC_PER_USEC
before calling poll_select_set_timeout() -> timespec64_valid(). Both
operands of the seconds sum are unbounded user-controlled signed long.
A crafted pair where tv_usec is a negative multiple of USEC_PER_SEC
drives the sum across the wrap boundary - e.g.
{ .tv_sec = LONG_MIN, .tv_usec = -1000000 }
yields sec = LONG_MAX, nsec = 0, which passes timespec64_valid() and
then flows through timespec64_add_safe(), which saturates the absolute
deadline to TIME64_MAX (clamped further to KTIME_MAX downstream).
select(2) therefore blocks effectively forever instead of returning
-EINVAL as POSIX requires for a negative timeout.
Only the legacy __NR_select syscall takes this path. pselect6, ppoll,
poll and epoll_pwait2 all hand the user's two fields directly to
poll_select_set_timeout(), which validates *before* doing any
arithmetic:
/* fs/select.c:271 -- the validator */
int poll_select_set_timeout(struct timespec64 *to, time64_t sec, long nsec)
{
struct timespec64 ts = {.tv_sec = sec, .tv_nsec = nsec};
if (!timespec64_valid(&ts))
return -EINVAL;
...
}
/* include/linux/time64.h:97 -- timespec64_valid */
if (ts->tv_sec < 0) return false;
if ((unsigned long)ts->tv_nsec >= NSEC_PER_SEC) return false;
/* fs/select.c:744 do_pselect() (pselect6, pselect6_time32) */
if (get_timespec64(&ts, tsp)) return -EFAULT;
if (poll_select_set_timeout(to, ts.tv_sec, ts.tv_nsec)) return -EINVAL;
/* fs/select.c:1097 ppoll */
if (get_timespec64(&ts, tsp)) return -EFAULT;
if (poll_select_set_timeout(to, ts.tv_sec, ts.tv_nsec)) return -EINVAL;
/* fs/select.c:1065 poll -- timeout_msecs is int; >= 0 gates the math */
if (timeout_msecs >= 0)
poll_select_set_timeout(to, timeout_msecs / MSEC_PER_SEC,
NSEC_PER_MSEC * (timeout_msecs % MSEC_PER_SEC));
/* fs/eventpoll.c:2512 epoll_pwait2 */
if (get_timespec64(&ts, timeout)) return -EFAULT;
if (poll_select_set_timeout(to, ts.tv_sec, ts.tv_nsec)) return -EINVAL;
In every one of these the wrap-prone arithmetic from kern_select()
simply does not exist; the user fields reach timespec64_valid()
unmodified. glibc routes the C-library select() through pselect6,
so the bug is reachable only via a direct syscall(__NR_select, ...).
The pre-validation negative check that used to live here was lost
when the syscall was switched to the poll_select_set_timeout() helper.
Restore it: reject tv_sec < 0 || tv_usec < 0 up front, mirroring what
glibc does in userspace. do_compat_select() has the same arithmetic
pattern but is only reachable on 32-bit compat and from a different
syscall entry; left for a follow-up so this change stays minimal.
Reproducer (returns -1/EINVAL on a fixed kernel; blocks indefinitely
on an unfixed one):
struct timeval tv = { .tv_sec = LONG_MIN, .tv_usec = -1000000 };
fd_set r;
int pfd[2];
pipe(pfd);
FD_ZERO(&r);
FD_SET(pfd[0], &r);
syscall(__NR_select, pfd[0] + 1, &r, NULL, NULL, &tv);

The assert in the doctest used `>= 10`, which only checks that the
capacity can hold `additional` elements, ignoring the existing length
of `v`. The correct check should ensure there is room for `additional`
*extra* elements on top of what is already in the vector.
Fix the assert to use `>= v.len() + 10` so the example accurately
reflects the actual semantics of the function.

Add a new device-mapper target "dm-inlinecrypt" that is similar to
dm-crypt but uses the blk-crypto API instead of the regular crypto API.
This allows it to take advantage of inline encryption hardware such as
that commonly built into UFS host controllers.
The table syntax matches dm-crypt's, but for now only a stripped-down
set of parameters is supported. For example, for now AES-256-XTS is the
only supported cipher.
dm-inlinecrypt is based on Android's dm-default-key with the
controversial passthrough support removed. Note that due to the removal
of passthrough support, use of dm-inlinecrypt in combination with
fscrypt causes double encryption of file contents (similar to dm-crypt +
fscrypt), with the fscrypt layer not being able to use the inline
encryption hardware. This makes dm-inlinecrypt unusable on systems such
as Android that use fscrypt and where a more optimized approach is
needed. It is however suitable as a replacement for dm-crypt.
dm-inlinecrypt supports both keyring key and hex key, the former avoids
the key to be exposed in dm-table message. Similar to dm-default-key in
Android, it will fallabck to the software block crypto once the inline
crypto hardware cannot support the expected cipher.
Test:
dmsetup create inlinecrypt_logon --table "0 `blockdev --getsz $1` \
inlinecrypt aes-xts-plain64 :64:logon:fde:dminlinecrypt_test_key 0 $1 0"

====================
vsock/virtio: fix vsockmon tap skb construction
While reviewing the patch posted by Yiqi Sun [1] to fix an issue in
virtio_transport_build_skb(), I discovered another issue related to
the offset and length of the payload to be copied in the new skb.
This was introduced when we did the skb conversion, and fixed by
patch 1.
Patch 2 fixes the issue found by Yiqi Sun in a different way: using
iov_iter_kvec() to properly initialize all the iov_iter fields and
removing the linear vs non-linear split like we alredy do in
vhost-vsock.
It could have been a single patch, but since there were two affected
commits, I decided to keep the fixes separate.

For non-linear skbs, virtio_transport_build_skb() goes through
virtio_transport_copy_nonlinear_skb() to copy the original payload
in the new skb to be delivered to the vsockmon tap device.
This manually initializes an iov_iter but does not set iov_iter.count.
Since the iov_iter is zero-initialized, the copy length is zero and no
payload is actually copied to the monitor interface, leaving data
un-initialized.
Fix this by removing the linear vs non-linear split and using
skb_copy_datagram_iter() with iov_iter_kvec() for all cases, as
vhost-vsock already does. This handles both linear and non-linear skbs,
properly initializes the iov_iter, and removes the now unused
virtio_transport_copy_nonlinear_skb().
While touching this code, let's also check the return value of
skb_copy_datagram_iter(), even though it's unlikely to fail.

virtio_transport_build_skb() builds a new skb to be delivered to the
vsockmon tap device. To build the new skb, it uses the original skb
data length as payload length, but as the comment notes, the original
packet stored in the skb may have been split in multiple packets, so we
need to use the length in the header, which is correctly updated before
the packet is delivered to the tap, and the offset for the data.
This was also similar to what we did before commit 71dc9ec9ac7d
("virtio/vsock: replace virtio_vsock_pkt with sk_buff") where we probably
missed something during the skb conversion.
Also update the comment above, which was left stale by the skb
conversion and still mentioned a buffer pointer that no longer exists.

Charles Keepax <ckeepax@opensource.cirrus.com> says:
Add a new SoundWire enumeration helper function, many drivers have
almost identical code in runtime resume so it makes sense to move this
to the core.
It is worth noting this is really step one of a larger process, there
are a few drivers that do more custom things and are not covered by this
series. But this series picks up the low hanging fruit and moves things
in a good direction.
The next step is to look at drivers that also wait at probe time, where
the unattached_request flag is not going to be valid.

Add a new helper function to wait for the device to enumerate
and be initialised by the SoundWire core. Most of the SoundWire
drivers have very similar boiler plate code in their runtime
resume, and that boiler plate tends to access various internals
of the SoundWire structs which is a mild layering violation.
Adding a new core helper function greatly eases both of these
issues.

In the HSR (High-availability Seamless Redundancy) protocol, node
information is maintained in the node_db. When a supervision frame is
received, node->addr_B_port is updated to track the receiving port type
(e.g., HSR_PT_SLAVE_B).
If the underlying physical interface associated with this slave port is
removed (e.g., via `ip link del`), hsr_del_port() frees the hsr_port
object. However, the stale node->addr_B_port reference is kept in the
node_db until the node ages out.
Subsequently, if userspace queries the node status via the Netlink
command HSR_C_GET_NODE_STATUS, the kernel calls hsr_get_node_data().
This function unconditionally dereferences the pointer returned by
hsr_port_get_hsr():
if (node->addr_B_port != HSR_PT_NONE) {
port = hsr_port_get_hsr(hsr, node->addr_B_port);
*addr_b_ifindex = port->dev->ifindex; // <-- NULL deref
}
If the slave port has been deleted, hsr_port_get_hsr() returns NULL,
resulting in a kernel panic.
Oops: general protection fault, probably for non-canonical address

Fix this by adding a proper NULL pointer check. If the port lookup fails
due to a stale port type, gracefully treat it as if no valid port exists
and assign -1 to the interface index.
Steps to reproduce:
1. Create an HSR interface with two slave devices.
2. Receive a supervision frame to populate node_db with
addr_B_port assigned to SLAVE_B.
3. Delete the underlying slave device B.
4. Send an HSR_C_GET_NODE_STATUS Netlink message.

If a GPIO line has a fixed direction, report an error if a consumer
anyway tries to set the direction to something other than what it is
hardcoded to.
This didn't happen much before because what we supported was all lines
input or output and then the implementer would probably not specify the
direction registers, but with sparse fixed direction we can have
a mixture so let's take this into account.
As a consequence, since gpio_regmap_set_direction() can now fail, alter
the semantics in gpio_regmap_direction_output() such that we first check
if we can set the direction to output before we set the value and the
direction.
