Linus Torvalds 090472ed9c USB / PHY / Thunderbolt fixes and ids for 6.7-rc3
Here are a number of reverts, fixes, and new device ids for 6.7-rc3 for
 the USB, PHY, and Thunderbolt driver subsystems.  Include in here are:
   - reverts of some PHY drivers that went into 6.7-rc1 that shouldn't
     have been merged yet, the author is reworking them based on review
     comments as they were using older apis that shouldn't be used
     anymore for newer drivers
   - small thunderbolt driver fixes for reported issues
   - USB driver fixes for a variety of small issues in dwc3, typec, xhci,
     and other smaller drivers.
   - new device ids for usb-serial and onboard_usb_hub drivers.
 
 All of these have been in linux-next with no reported issues.

Pull vfs fixes from Christian Brauner:

 - Avoid calling back into LSMs from vfs_getattr_nosec() calls.

   IMA used to query inode properties accessing raw inode fields without
   dedicated helpers. That was finally fixed a few releases ago by
   forcing IMA to use vfs_getattr_nosec() helpers.

   The goal of the vfs_getattr_nosec() helper is to query for attributes
   without calling into the LSM layer which would be quite problematic
   because incredibly IMA is called from __fput()...

     __fput()
       -> ima_file_free()

   What it does is to call back into the filesystem to update the file's
   IMA xattr. Querying the inode without using vfs_getattr_nosec() meant
   that IMA didn't handle stacking filesystems such as overlayfs
   correctly. So the switch to vfs_getattr_nosec() is quite correct. But
   the switch to vfs_getattr_nosec() revealed another bug when used on
   stacking filesystems:

     __fput()
       -> ima_file_free()
          -> vfs_getattr_nosec()
             -> i_op->getattr::ovl_getattr()
                -> vfs_getattr()
                   -> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr()
                      -> security_inode_getattr() # calls back into LSMs

   Now, if that __fput() happens from task_work_run() of an exiting task
   current->fs and various other pointer could already be NULL. So
   anything in the LSM layer relying on that not being NULL would be
   quite surprised.

   Fix that by passing the information that this is a security request
   through to the stacking filesystem by adding a new internal
   ATT_GETATTR_NOSEC flag. Now the callchain becomes:

     __fput()
       -> ima_file_free()
          -> vfs_getattr_nosec()
             -> i_op->getattr::ovl_getattr()
                -> if (AT_GETATTR_NOSEC)
                          vfs_getattr_nosec()
                   else
                          vfs_getattr()
                   -> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr()

 - Fix a bug introduced with the iov_iter rework from last cycle.

   This broke /proc/kcore by copying too much and without the correct
   offset.

 - Add a missing NULL check when allocating the root inode in
   autofs_fill_super().

 - Fix stable writes for multi-device filesystems (xfs, btrfs etc) and
   the block device pseudo filesystem.

   Stable writes used to be a superblock flag only, making it a per
   filesystem property. Add an additional AS_STABLE_WRITES mapping flag
   to allow for fine-grained control.

 - Ensure that offset_iterate_dir() returns 0 after reaching the end of
   a directory so it adheres to getdents() convention.

David Howells b590eb41be afs: Fix file locking on R/O volumes to operate in local mode
AFS doesn't really do locking on R/O volumes as fileservers don't maintain
state with each other and thus a lock on a R/O volume file on one
fileserver will not be be visible to someone looking at the same file on
another fileserver.

Further, the server may return an error if you try it.

Fix this by doing what other AFS clients do and handle filelocking on R/O
volume files entirely within the client and don't touch the server.

Masahiro Yamada c0a8574204 arm64: add dependency between vmlinuz.efi and Image
A common issue in Makefile is a race in parallel building.

You need to be careful to prevent multiple threads from writing to the
same file simultaneously.

Commit 3939f33450 ("ARM: 8418/1: add boot image dependencies to not
generate invalid images") addressed such a bad scenario.

A similar symptom occurs with the following command:

  $ make -j$(nproc) ARCH=arm64 Image vmlinuz.efi
    [ snip ]
    SORTTAB vmlinux
    OBJCOPY arch/arm64/boot/Image
    OBJCOPY arch/arm64/boot/Image
    AS      arch/arm64/boot/zboot-header.o
    PAD     arch/arm64/boot/vmlinux.bin
    GZIP    arch/arm64/boot/vmlinuz
    OBJCOPY arch/arm64/boot/vmlinuz.o
    LD      arch/arm64/boot/vmlinuz.efi.elf
    OBJCOPY arch/arm64/boot/vmlinuz.efi

The log "OBJCOPY arch/arm64/boot/Image" is displayed twice.

It indicates that two threads simultaneously enter arch/arm64/boot/
and write to arch/arm64/boot/Image.

It occasionally leads to a build failure:

  $ make -j$(nproc) ARCH=arm64 Image vmlinuz.efi
    [ snip ]
    SORTTAB vmlinux
    OBJCOPY arch/arm64/boot/Image
    PAD     arch/arm64/boot/vmlinux.bin
  truncate: Invalid number: 'arch/arm64/boot/vmlinux.bin'
  make[2]: *** [drivers/firmware/efi/libstub/Makefile.zboot:13:
  arch/arm64/boot/vmlinux.bin] Error 1
  make[2]: *** Deleting file 'arch/arm64/boot/vmlinux.bin'
  make[1]: *** [arch/arm64/Makefile:163: vmlinuz.efi] Error 2
  make[1]: *** Waiting for unfinished jobs....
  make: *** [Makefile:234: __sub-make] Error 2

vmlinuz.efi depends on Image, but such a dependency is not specified
in arch/arm64/Makefile.

We don't support CRUD-inspired message types in YNL too well.
One aspect that currently trips us up is the fact that single

This leads to duplicate entries in the id-to-string tables:

Jann Horn 53f2cb491b tls: fix NULL deref on tls_sw_splice_eof() with empty record
syzkaller discovered that if tls_sw_splice_eof() is executed as part of
sendfile() when the plaintext/ciphertext sk_msg are empty, the send path
gets confused because the empty ciphertext buffer does not have enough
space for the encryption overhead. This causes tls_push_record() to go on
the `split = true` path (which is only supposed to be used when interacting
with an attached BPF program), and then get further confused and hit the
tls_merge_open_record() path, which then assumes that there must be at
least one populated buffer element, leading to a NULL deref.

It is possible to have empty plaintext/ciphertext buffers if we previously
bailed from tls_sw_sendmsg_locked() via the tls_trim_both_msgs() path.
tls_sw_push_pending_record() already handles this case correctly; let's do
the same check in tls_sw_splice_eof().

Paolo Abeni e50a8061fe Merge branch 'ice-restore-timestamp-config-after-reset'
Tony Nguyen says:

====================
ice: restore timestamp config after reset

Jake Keller says:

We recently discovered during internal validation that the ice driver has
not been properly restoring Tx timestamp configuration after a device reset,
which resulted in application failures after a device reset.

After some digging, it turned out this problem is two-fold. Since the
introduction of the PTP support the driver has been clobbering the storage
of the current timestamp configuration during reset. Thus after a reset, the
driver will no longer perform Tx or Rx timestamps, and will report
timestamp configuration as disabled if SIOCGHWTSTAMP ioctl is issued.

In addition, the recently merged auxiliary bus support code missed that
PFINT_TSYN_MSK must be reprogrammed on the clock owner for E822 devices.
Failure to restore this register configuration results in the driver no
longer responding to interrupts from other ports. Depending on the traffic
pattern, this can either result in increased latency responding to
timestamps on the non-owner ports, or it can result in the driver never
reporting any timestamps. The configuration of PFINT_TSYN_MSK was only done
during initialization. Due to this, the Tx timestamp issue persists even if
userspace reconfigures timestamping.

This series fixes both issues, as well as removes a redundant Tx ring field
since we can rely on the skb flag as the primary detector for a Tx timestamp
request.

Note that I don't think this series will directly apply to older stable
releases (even v6.6) as we recently refactored a lot of the PTP code to
support auxiliary bus. Patch 2/3 only matters for the post-auxiliary bus
implementation. The principle of patch 1/3 and 3/3 could apply as far back
as the initial PTP support, but I don't think it will apply cleanly as-is.

Jacob Keller 7758017911 ice: restore timestamp configuration after device reset
The driver calls ice_ptp_cfg_timestamp() during ice_ptp_prepare_for_reset()
to disable timestamping while the device is resetting. This operation
destroys the user requested configuration. While the driver does call
ice_ptp_cfg_timestamp in ice_rebuild() to restore some hardware settings
after a reset, it unconditionally passes true or false, resulting in
failure to restore previous user space configuration.

This results in a device reset forcibly disabling timestamp configuration
regardless of current user settings.

This was not detected previously due to a quirk of the LinuxPTP ptp4l
application. If ptp4l detects a missing timestamp, it enters a fault state
and performs recovery logic which includes executing SIOCSHWTSTAMP again,
restoring the now accidentally cleared configuration.

Not every application does this, and for these applications, timestamps
will mysteriously stop after a PF reset, without being restored until an
application restart.

Fix this by replacing ice_ptp_cfg_timestamp() with two new functions:

1) ice_ptp_disable_timestamp_mode() which unconditionally disables the
   timestamping logic in ice_ptp_prepare_for_reset() and ice_ptp_release()

2) ice_ptp_restore_timestamp_mode() which calls
   ice_ptp_restore_tx_interrupt() to restore Tx timestamping configuration,
   calls ice_set_rx_tstamp() to restore Rx timestamping configuration, and
   issues an immediate TSYN_TX interrupt to ensure that timestamps which
   may have occurred during the device reset get processed.

Modify the ice_ptp_set_timestamp_mode to directly save the user
configuration and then call ice_ptp_restore_timestamp_mode. This way, reset
no longer destroys the saved user configuration.

This obsoletes the ice_set_tx_tstamp() function which can now be safely
removed.

With this change, all devices should now restore Tx and Rx timestamping
functionality correctly after a PF reset without application intervention.

Jacob Keller 7d606a1e2d ice: unify logic for programming PFINT_TSYN_MSK
Commit d938a8cca8 ("ice: Auxbus devices & driver for E822 TS") modified
how Tx timestamps are handled for E822 devices. On these devices, only the
clock owner handles reading the Tx timestamp data from firmware. To do
this, the PFINT_TSYN_MSK register is modified from the default value to one
which enables reacting to a Tx timestamp on all PHY ports.

The driver currently programs PFINT_TSYN_MSK in different places depending
on whether the port is the clock owner or not. For the clock owner, the
PFINT_TSYN_MSK value is programmed during ice_ptp_init_owner just before
calling ice_ptp_tx_ena_intr to program the PHY ports.

For the non-clock owner ports, the PFINT_TSYN_MSK is programmed during
ice_ptp_init_port.

If a large enough device reset occurs, the PFINT_TSYN_MSK register will be
reset to the default value in which only the PHY associated directly with
the PF will cause the Tx timestamp interrupt to trigger.

The driver lacks logic to reprogram the PFINT_TSYN_MSK register after a
device reset. For the E822 device, this results in the PF no longer
responding to interrupts for other ports. This results in failure to
deliver Tx timestamps to user space applications.

Rename ice_ptp_configure_tx_tstamp to ice_ptp_cfg_tx_interrupt, and unify
the logic for programming PFINT_TSYN_MSK and PFINT_OICR_ENA into one place.
This function will program both registers according to the combination of
user configuration and device requirements.

This ensures that PFINT_TSYN_MSK is always restored when we configure the
Tx timestamp interrupt.

Jacob Keller 0ffb08b1a4 ice: remove ptp_tx ring parameter flag
Before performing a Tx timestamp in ice_stamp(), the driver checks a ptp_tx
ring variable to see if timestamping is enabled on that ring. This value is
set for all rings whenever userspace configures Tx timestamping.

Ostensibly this was done to avoid wasting cycles checking other fields when
timestamping has not been enabled. However, for Tx timestamps we already
get an individual per-SKB flag indicating whether userspace wants to
request a timestamp on that packet. We do not gain much by also having
a separate flag to check for whether timestamping was enabled.

In fact, the driver currently fails to restore the field after a PF reset.
Because of this, if a PF reset occurs, timestamps will be disabled.

Since this flag doesn't add value in the hotpath, remove it and always
provide a timestamp if the SKB flag has been set.

A following change will fix the reset path to properly restore user
timestamping configuration completely.

This went unnoticed for some time because one of the most common
applications using Tx timestamps, ptp4l, will reconfigure the socket as
part of its fault recovery logic.

Suman Ghosh 4aa1d8f89b octeontx2-pf: Fix ntuple rule creation to direct packet to VF with higher Rx queue than its PF
It is possible to add a ntuple rule which would like to direct packet to
a VF whose number of queues are greater/less than its PF's queue numbers.
For example a PF can have 2 Rx queues but a VF created on that PF can have
8 Rx queues. As of today, ntuple rule will reject rule because it is
checking the requested queue number against PF's number of Rx queues.
As a part of this fix if the action of a ntuple rule is to move a packet
to a VF's queue then the check is removed. Also, a debug information is
printed to aware user that it is user's responsibility to cross check if
the requested queue number on that VF is a valid one.

Stefano Stabellini 7bf9a6b465 arm/xen: fix xen_vcpu_info allocation alignment
xen_vcpu_info is a percpu area than needs to be mapped by Xen.
Currently, it could cross a page boundary resulting in Xen being unable
to map it:

[    0.567318] kernel BUG at arch/arm64/xen/../../arm/xen/enlighten.c:164!
[    0.574002] Internal error: Oops - BUG: 00000000f2000800 [#1] PREEMPT SMP

Fix the issue by using __alloc_percpu and requesting alignment for the
memory allocation.

Arnd Bergmann 0e6c4fe782 nvme: tcp: fix compile-time checks for TLS mode
When CONFIG_NVME_KEYRING is enabled as a loadable module, but the TCP
host code is built-in, it fails to link:

arm-linux-gnueabi-ld: drivers/nvme/host/tcp.o: in function `nvme_tcp_setup_ctrl':
tcp.c:(.text+0x1940): undefined reference to `nvme_tls_psk_default'

The problem is that the compile-time conditionals are inconsistent here,
using a mix of #ifdef CONFIG_NVME_TCP_TLS, IS_ENABLED(CONFIG_NVME_TCP_TLS)
and IS_ENABLED(CONFIG_NVME_KEYRING) checks, with CONFIG_NVME_KEYRING
controlling whether the implementation is actually built.

Change it to use IS_ENABLED(CONFIG_NVME_KEYRING) checks consistently,
which should help readability and make it less error-prone. Combining
it with the check for the ctrl->opts->tls flag lets the compiler drop
all the TLS code in configurations without this feature, which also
helps runtime behavior in addition to avoiding the link failure.

To make it possible for the compiler to build the dead code, both
the tls_handshake_timeout variable and the TLS specific members
of nvme_tcp_queue need to be moved out of the #ifdef block as well,
but at least the former of these gets optimized out again.

Arnd Bergmann 65e2a74c44 nvme: target: fix Kconfig select statements
When the NVME target code is built-in but its TCP frontend is a loadable
module, enabling keyring support causes a link failure:

x86_64-linux-ld: vmlinux.o: in function `nvmet_ports_make':
configfs.c:(.text+0x100a211): undefined reference to `nvme_keyring_id'

The problem is that CONFIG_NVME_TARGET_TCP_TLS is a 'bool' symbol that
depends on the tristate CONFIG_NVME_TARGET_TCP, so any 'select' from
it inherits the state of the tristate symbol rather than the intended
CONFIG_NVME_TARGET one that contains the actual call.

The same thing is true for CONFIG_KEYS, which itself is required for
NVME_KEYRING.

Arnd Bergmann d78abcbabe nvme: target: fix nvme_keyring_id() references
In configurations without CONFIG_NVME_TARGET_TCP_TLS, the keyring
code might not be available, or using it will result in a runtime
failure:

x86_64-linux-ld: vmlinux.o: in function `nvmet_ports_make':
configfs.c:(.text+0x100a211): undefined reference to `nvme_keyring_id'

Add a check to ensure we only check the keyring if there is a chance
of it being used, which avoids both the runtime and link-time
problems.

Will Deacon acfa60dbe0 arm64: mm: Fix "rodata=on" when CONFIG_RODATA_FULL_DEFAULT_ENABLED=y
When CONFIG_RODATA_FULL_DEFAULT_ENABLED=y, passing "rodata=on" on the
kernel command-line (rather than "rodata=full") should turn off the
"full" behaviour, leaving writable linear aliases of read-only kernel
memory. Unfortunately, the option has no effect in this situation and
the only way to disable the "rodata=full" behaviour is to disable rodata
protection entirely by passing "rodata=off".

Fix this by parsing the "on" and "off" options in the arch code,
additionally enforcing that 'rodata_full' cannot be set without also
setting 'rodata_enabled', allowing us to simplify a couple of checks
in the process.
