usb: gadget: uvc: Prevent buffer overflow in setup handler
476d038 
BugLink: https://bugs.launchpad.net/bugs/2003139

commit 4c92670 upstream.

Setup function uvc_function_setup permits control transfer
requests with up to 64 bytes of payload (UVC_MAX_REQUEST_SIZE),
data stage handler for OUT transfer uses memcpy to copy req->actual
bytes to uvc_event->data.data array of size 60. This may result
in an overflow of 4 bytes.

BugLink: https://bugs.launchpad.net/bugs/2003139

commit f0052d7 upstream.

The EM05-G modem has 2 USB configurations that are configurable via the AT
command AT+QCFG="usbnet",[ 0 | 2 ] which make the modem enumerate with
the following interfaces, respectively:

"RMNET" : AT + DIAG + NMEA + Modem + QMI
"MBIM"  : MBIM + AT + DIAG + NMEA + Modem

xhci: Apply XHCI_RESET_TO_DEFAULT quirk to ADL-N
4f18882 
BugLink: https://bugs.launchpad.net/bugs/2003139

commit fed70b6 upstream.

ADL-N systems have the same issue as ADL-P, where a large boot firmware
delay is seen if USB ports are left in U3 at shutdown. So apply the
XHCI_RESET_TO_DEFAULT quirk to ADL-N as well.

This patch depends on commit 34cd2db ("xhci: Add quirk to reset
host back to default state at shutdown").

The issue it fixes is a ~20s boot time delay when booting from S5. It
affects ADL-N devices, and ADL-N support was added starting from v5.16.

commit de5dc44 upstream.

When a MAC address is not assigned to the VF, that portion of the message
sent to the VF is not set. The memory, however, is allocated from the
stack meaning that information may be leaked to the VM. Initialize the
message buffer to 0 so that no information is passed to the VM in this
case.

net: loopback: use NET_NAME_PREDICTABLE for name_assign_type
a958803 
BugLink: https://bugs.launchpad.net/bugs/2003139

[ Upstream commit 31d929d ]

When the name_assign_type attribute was introduced (commit
685343f, "net: add name_assign_type netdev attribute"), the
loopback device was explicitly mentioned as one which would make use
of NET_NAME_PREDICTABLE:

    The name_assign_type attribute gives hints where the interface name of a
    given net-device comes from. These values are currently defined:
...
      NET_NAME_PREDICTABLE:
        The ifname has been assigned by the kernel in a predictable way
        that is guaranteed to avoid reuse and always be the same for a
        given device. Examples include statically created devices like
        the loopback device [...]

Switch to that so that reading /sys/class/net/lo/name_assign_type
produces something sensible instead of returning -EINVAL.

net/ulp: prevent ULP without clone op from entering the LISTEN status
2c34aed 
When an ULP-enabled socket enters the LISTEN status, the listener ULP data
pointer is copied inside the child/accepted sockets by sk_clone_lock().

The relevant ULP can take care of de-duplicating the context pointer via
the clone() operation, but only MPTCP and SMC implement such op.

Other ULPs may end-up with a double-free at socket disposal time.

We can't simply clear the ULP data at clone time, as TLS replaces the
socket ops with custom ones assuming a valid TLS ULP context is
available.

Instead completely prevent clone-less ULP sockets from entering the
LISTEN status.

net/ulp: use consistent error code when blocking ULP
31c2ad4 
The referenced commit changed the error code returned by the kernel
when preventing a non-established socket from attaching the ktls
ULP. Before to such a commit, the user-space got ENOTCONN instead
of EINVAL.

The existing self-tests depend on such error code, and the change
caused a failure:

  RUN           global.non_established ...
 tls.c:1673:non_established:Expected errno (22) == ENOTCONN (107)
 non_established: Test failed at step #3
          FAIL  global.non_established

In the unlikely event existing applications do the same, address
the issue by restoring the prior error code in the above scenario.

Note that the only other ULP performing similar checks at init
time - smc_ulp_ops - also fails with ENOTCONN when trying to attach
the ULP to a non-established socket.

NFSD: fix use-after-free in __nfs42_ssc_open()
e549585 
Problem caused by source's vfsmount being unmounted but remains
on the delayed unmount list. This happens when nfs42_ssc_open()
return errors.

Fixed by removing nfsd4_interssc_connect(), leave the vfsmount
for the laundromat to unmount when idle time expires.

We don't need to call nfs_do_sb_deactive when nfs42_ssc_open
return errors since the file was not opened so nfs_server->active
was not incremented. Same as in nfsd4_copy, if we fail to
launch nfsd4_do_async_copy thread then there's no need to
call nfs_do_sb_deactive

NFS: Clear the file access cache upon login
2cbb606 
BugLink: https://bugs.launchpad.net/bugs/2003053

POSIX typically only refreshes the user's supplementary group
information upon login. Since NFS servers may often refresh their
concept of the user supplementary group membership at their own cadence,
it is possible for the NFS client's access cache to become stale due to
the user's group membership changing on the server after the user has
already logged in on the client.
While it is reasonable to expect that such group membership changes are
rare, and that we do not want to optimise the cache to accommodate them,
it is also not unreasonable for the user to expect that if they log out
and log back in again, that the staleness would clear up.

NFS: Judge the file access cache's timestamp in rcu path
bcf920d 
BugLink: https://bugs.launchpad.net/bugs/2003053

If the user's login time is newer than the cache's timestamp,
we expect the cache may be stale and need to clear.
The stale cache will remain in the list's tail if no other
users operate on that inode.
Once the user accesses the inode, the stale cache will be
returned in rcu path.

UBUNTU: SAUCE: Fix inet_csk_listen_start after CVE-2023-0461
2dd9a20 
When adding "net/ulp: prevent ULP without clone op from entering the
LISTEN status" code which changed the error code variable was added.
However, without a different v6.2 change which lets ->get_port() return
a proper errno, we rely on the pre-set value or the error variable.
Adding this right before the call to make it clear where it is needed.

nfsd: Don't keep looking up unhashed files in the nfsd file cache

If a file is unhashed, then we're going to reject it anyway and retry,
so make sure we skip it when we're doing the RCU lockless lookup.
This avoids a number of unnecessary nfserr_jukebox returns from
nfsd_file_acquire()
