Merge tag 'vfs-6.11-rc1.fixes.2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs fixes from Christian Brauner:
"VFS:
- The new 64bit mount ids start after the old mount id, i.e., at the
first non-32 bit value. However, we started counting one id too
late and thus lost 4294967296 as the first valid id. Fix that.
- Update a few comments on some vfs_*() creation helpers.
- Move copying of the xattr name out from the locks required to start
a filesystem write.
- Extend the filelock lock UAF fix to the compat code as well.
- Now that we added the ability to look up an inode under RCU it's
possible that lockless hash lookup can find and lock an inode after
it gets I_FREEING set. It then waits until inode teardown in
evict() is finished.
The flag however is still set after evict() has woken up all
waiters. If the inode lock is taken late enough on the waiting side
after hash removal and wakeup happened the waiting thread will
never be woken.
Before RCU based lookup this was synchronized via the
inode_hash_lock. But since unhashing requires the inode lock as
well we can check whether the inode is unhashed while holding inode
lock even without holding inode_hash_lock.
pidfd:
- The nsproxy structure contains nearly all of the namespaces
associated with a task. When a namespace type isn't supported
nsproxy might contain a NULL pointer or always point to the initial
namespace type. The logic isn't consistent. So when deriving
namespace fds we need to ensure that the namespace type is
supported.
First, so that we don't risk dereferncing NULL pointers. The
correct bigger fix would be to change all namespaces to always set
a valid namespace pointer in struct nsproxy independent of whether
or not it is compiled in. But that requires quite a few changes.
Second, so that we don't allow deriving namespace fds when the
namespace type doesn't exist and thus when they couldn't also be
derived via /proc/self/ns/.
- Add missing selftests for the new pidfd ioctls to derive namespace
fds. This simply extends the already existing testsuite.
netfs:
- Fix debug logging and fix kconfig variable name so it actually
works.
- Fix writeback that goes both to the server and cache. The streams
are only activated once a subreq is added. When a server write
happens the subreq doesn't need to have finished by the time the
cache write is started. If the server write has already finished by
the time the cache write is about to start the cache write will
operate on a folio that might already have been reused. Fix this by
preactivating the cache write.
- Limit cachefiles subreq size for cache writes to MAX_RW_COUNT"

+maintainers:

+
+description:
+ The Global Command Engine (GCE) is an instruction based, multi-threaded,
+ single-core command dispatcher for MediaTek hardware. The Command Queue
+ (CMDQ) mailbox driver is a driver for GCE, implemented using the Linux
+ mailbox framework. It is used to receive messages from mailbox consumers
+ and configure GCE to execute the specified instruction set in the message.
+ We use mediatek,gce-mailbox.yaml to define the properties for CMDQ mailbox
+ driver. A device driver that uses the CMDQ driver to configure its hardware
+ registers is a mailbox consumer. The mailbox consumer can request a mailbox
+ channel corresponding to a GCE hardware thread to send a message, specifying
+ that the GCE thread to configure its hardware. The mailbox provider can also
+ reserve a mailbox channel to configure GCE hardware register by the specific
+ GCE thread. This binding defines the common GCE properties for both mailbox
+ provider and consumers.
+
+properties:
+ mediatek,gce-events:
+ description:
+ GCE has an event table in SRAM, consisting of 1024 event IDs (0~1023).
+ Each event ID has a boolean event value with the default value 0.
+ The property mediatek,gce-events is used to obtain the event IDs.
+ Some gce-events are hardware-bound and cannot be changed by software.
+ For instance, in MT8195, when VDO0_MUTEX is stream done, VDO_MUTEX will
+ send an event signal to GCE, setting the value of event ID 597 to 1.
+ Similarly, in MT8188, the value of event ID 574 will be set to 1 when
+ VOD0_MUTEX is stream done.
+ On the other hand, some gce-events are not hardware-bound and can be
+ changed by software. For example, in MT8188, we can set the value of
+ event ID 855, which is not bound to any hardware, to 1 when the driver
+ in the secure world completes a task. However, in MT8195, event ID 855
+ is already bound to VDEC_LAT1, so we need to select another event ID to
+ achieve the same purpose. This event ID can be any ID that is not bound
+ to any hardware and is not yet used in any software driver.
+ To determine if the event ID is bound to the hardware or used by a
+ software driver, refer to the GCE header
+ include/dt-bindings/gce/<chip>-gce.h of each chip.

This defines a choice group and accepts any of the above attributes as
-options. A choice can only be of type bool or tristate. If no type is

-While a boolean choice only allows a single config entry to be
-selected, a tristate choice also allows any number of config entries
-to be set to 'm'. This can be used if multiple drivers for a single
-hardware exists and only a single driver can be compiled/loaded into
-the kernel, but all drivers can be compiled as modules.

- On 64-bit builds, this reduces the size of the address table by 50%,
