Mixed with some fixes and cleanups, this brings in reasonably complete
fscrypt support to CephFS! The list of things which don't work with encryption should be fairly short, mostly around the edges: fallocate (not supported well in CephFS to begin with), copy_file_range (requires re-encryption), non-default striping patterns. This was a multi-year effort principally by Jeff Layton with assistance from Xiubo Li, Luís Henriques and others, including several dependant changes in the MDS, netfs helper library and fscrypt framework itself. -----BEGIN PGP SIGNATURE----- iQFHBAABCAAxFiEEydHwtzie9C7TfviiSn/eOAIR84sFAmT4pl4THGlkcnlvbW92 QGdtYWlsLmNvbQAKCRBKf944AhHzi5kzB/4sMgzZyUa3T1vA/G2pPvEkyy1qDxsW y+o4dDMWA9twcrBVpNuGd54wbXpmO/LAekHEdorjayH+f0zf10MsnP1ePz9WB3NG jr7RRujb+Gpd2OFYJXGSEbd3faTg8M2kpGCCrVe7SFNoyu8z9NwFItwWMog5aBjX ODGQrq+kA4ARA6xIqwzF5gP0zr+baT9rWhQdm7Xo9itWdosnbyDLJx1dpEfLuqBX te3SmifDzedn3Gw73hdNo/+ybw0kHARoK+RmXCTsoDDQw+JsoO9KxZF5Q8QcDELq 2woPNp0Hl+Dm4MkzGnPxv56Qj8ZDViS59syXC0CfGRmu4nzF1Rw+0qn5 =/WlE -----END PGP SIGNATURE----- Merge tag 'ceph-for-6.6-rc1' of https://github.com/ceph/ceph-client Pull ceph updates from Ilya Dryomov: "Mixed with some fixes and cleanups, this brings in reasonably complete fscrypt support to CephFS!

drbd: swap bvec_set_page len and offset
bvec_set_page has the following signature:
static inline void bvec_set_page(struct bio_vec *bv, struct page *page,
unsigned int len, unsigned int offset)
However, the usage in DRBD swaps the len and offset parameters. This
leads to a bvec with length=0 instead of the intended length=4096, which
causes sock_sendmsg to return -EIO.
This leaves DRBD unable to transmit any pages and thus completely
broken.
Swapping the parameters fixes the regression.

null_blk: fix poll request timeout handling
When doing io_uring benchmark on /dev/nullb0, it's easy to crash the
kernel if poll requests timeout triggered, as reported by David. [1]
BUG: kernel NULL pointer dereference, address: 0000000000000008
Workqueue: kblockd blk_mq_timeout_work
RIP: 0010:null_timeout_rq+0x4e/0x91
Call Trace:
? null_timeout_rq+0x4e/0x91
blk_mq_handle_expired+0x31/0x4b
bt_iter+0x68/0x84
? bt_tags_iter+0x81/0x81
__sbitmap_for_each_set.constprop.0+0xb0/0xf2
? __blk_mq_complete_request_remote+0xf/0xf
bt_for_each+0x46/0x64
? __blk_mq_complete_request_remote+0xf/0xf
? percpu_ref_get_many+0xc/0x2a
blk_mq_queue_tag_busy_iter+0x14d/0x18e
blk_mq_timeout_work+0x95/0x127
process_one_work+0x185/0x263
worker_thread+0x1b5/0x227
This is indeed a race problem between null_timeout_rq() and null_poll().
null_poll() null_timeout_rq()
spin_lock(&nq->poll_lock)
list_splice_init(&nq->poll_list, &list)
spin_unlock(&nq->poll_lock)
while (!list_empty(&list))
req = list_first_entry()
list_del_init()
...
blk_mq_add_to_batch()
// req->rq_next = NULL
spin_lock(&nq->poll_lock)
// rq->queuelist->next == NULL
list_del_init(&rq->queuelist)
spin_unlock(&nq->poll_lock)
Fix these problems by setting requests state to MQ_RQ_COMPLETE under
nq->poll_lock protection, in which null_timeout_rq() can safely detect
this race and early return.
Note this patch just fix the kernel panic when request timeout happen.

rbd: use list_for_each_entry() helper
Convert list_for_each() to list_for_each_entry() so that the tmp list_head pointer and list_entry() call are no longer needed, which can reduce a few lines of code. No functional changed.

- Add uprobe support for the bpf_get_func_ip helper.
- Check skb ownership against full socket.
- Support for up to 12 arguments in BPF trampoline.
- Extend link_info for kprobe_multi and perf_event links.
Netfilter

the common information already populated in struct genl_info.
- Extend and use the yaml devlink specs to [re]generate the split ops.
- Introduce devlink selective dumps, to allow SF filtering SF based on
handle and other attributes.

Pull superblock updates from Christian Brauner:
"This contains the super rework that was ready for this cycle. The
first part changes the order of how we open block devices and allocate
superblocks, contains various cleanups, simplifications, and a new
mechanism to wait on superblock state changes.
This unblocks work to ultimately limit the number of writers to a
block device. Jan has already scheduled follow-up work that will be
ready for v6.7 and allows us to restrict the number of writers to a
given block device. That series builds on this work right here.
The second part contains filesystem freezing updates.
Overview:
The generic superblock changes are rougly organized as follows
(ignoring additional minor cleanups):
(1) Removal of the bd_super member from struct block_device.
This was a very odd back pointer to struct super_block with
unclear rules. For all relevant places we have other means to get
the same information so just get rid of this.
(2) Simplify rules for superblock cleanup.
Roughly, everything that is allocated during fs_context
initialization and that's stored in fs_context->s_fs_info needs
to be cleaned up by the fs_context->free() implementation before
the superblock allocation function has been called successfully.
After sget_fc() returned fs_context->s_fs_info has been
transferred to sb->s_fs_info at which point sb->kill_sb() if
fully responsible for cleanup. Adhering to these rules means that
cleanup of sb->s_fs_info in fill_super() is to be avoided as it's
brittle and inconsistent.
Cleanup shouldn't be duplicated between sb->put_super() as
sb->put_super() is only called if sb->s_root has been set aka
when the filesystem has been successfully born (SB_BORN). That
complexity should be avoided.
This also means that block devices are to be closed in
sb->kill_sb() instead of sb->put_super(). More details in the
lower section.
(3) Make it possible to lookup or create a superblock before opening
block devices
There's a subtle dependency on (2) as some filesystems did rely
on fill_super() to be called in order to correctly clean up
sb->s_fs_info. All these filesystems have been fixed.
(4) Switch most filesystem to follow the same logic as the generic
mount code now does as outlined in (3).
(5) Use the superblock as the holder of the block device. We can now
easily go back from block device to owning superblock.
(6) Export and extend the generic fs_holder_ops and use them as
holder ops everywhere and remove the filesystem specific holder
ops.
(7) Call from the block layer up into the filesystem layer when the
block device is removed, allowing to shut down the filesystem
without risk of deadlocks.
(8) Get rid of get_super().
We can now easily go back from the block device to owning
superblock and can call up from the block layer into the
filesystem layer when the device is removed. So no need to wade
through all registered superblock to find the owning superblock
anymore"

rbd: prevent busy loop when requesting exclusive lock
Due to rbd_try_acquire_lock() effectively swallowing all but
EBLOCKLISTED error from rbd_try_lock() ("request lock anyway") and
rbd_request_lock() returning ETIMEDOUT error not only for an actual
notify timeout but also when the lock owner doesn't respond, a busy
loop inside of rbd_acquire_lock() between rbd_try_acquire_lock() and
rbd_request_lock() is possible.
Requesting the lock on EBUSY error (returned by get_lock_owner_info()
if an incompatible lock or invalid lock owner is detected) makes very
little sense. The same goes for ETIMEDOUT error (might pop up pretty
much anywhere if osd_request_timeout option is set) and many others.
Just fail I/O requests on rbd_dev->acquiring_list immediately on any
error from rbd_try_lock().

rbd: retrieve and check lock owner twice before blocklisting
An attempt to acquire exclusive lock can race with the current lock owner closing the image: 1. lock is held by client123, rbd_lock() returns -EBUSY 2. get_lock_owner_info() returns client123 instance details 3. client123 closes the image, lock is released 4. find_watcher() returns 0 as there is no matching watcher anymore 5. client123 instance gets erroneously blocklisted Particularly impacted is mirror snapshot scheduler in snapshot-based mirroring since it happens to open and close images a lot (images are opened only for as long as it takes to take the next mirror snapshot, the same client instance is used for all images). To reduce the potential for erroneous blocklisting, retrieve the lock owner again after find_watcher() returns 0. If it's still there, make sure it matches the previously detected lock owner.

loop: do not enforce max_loop hard limit by (new) default
Problem: The max_loop parameter is used for 2 different purposes: 1) initial number of loop devices to pre-create on init 2) maximum number of loop devices to add on access/open() Historically, its default value (zero) caused 1) to create non-zero number of devices (CONFIG_BLK_DEV_LOOP_MIN_COUNT), and no hard limit on 2) to add devices with autoloading. However, the default value changed in commit |

nbd: automatically load module on genl access
Add a module alias to nbd.ko that allows the generic netlink core to automatically load the module when netlink messages for nbd are received. This frees the user from manually having to load the module before using nbd functionality via netlink. If the system policy allows it this can even be used to load the nbd module from containers which would otherwise not have access to the necessary module files to do a normal "modprobe nbd". For example this avoids the following error when using nbd-client: $ nbd-client localhost 10809 /dev/nbd0 ... Error: Couldn't resolve the nbd netlink family, make sure the nbd module is loaded and your nbd driver supports the netlink interface.

Networking changes for 6.5.
Core
----
- Rework the sendpage & splice implementations. Instead of feeding
data into sockets page by page extend sendmsg handlers to support
taking a reference on the data, controlled by a new flag called
MSG_SPLICE_PAGES. Rework the handling of unexpected-end-of-file
to invoke an additional callback instead of trying to predict what
the right combination of MORE/NOTLAST flags is.
Remove the MSG_SENDPAGE_NOTLAST flag completely.
- Implement SCM_PIDFD, a new type of CMSG type analogous to
SCM_CREDENTIALS, but it contains pidfd instead of plain pid.
- Enable socket busy polling with CONFIG_RT.
- Improve reliability and efficiency of reporting for ref_tracker.
- Auto-generate a user space C library for various Netlink families.
Protocols
---------
- Allow TCP to shrink the advertised window when necessary, prevent
sk_rcvbuf auto-tuning from growing the window all the way up to
tcp_rmem[2].
- Use per-VMA locking for "page-flipping" TCP receive zerocopy.
- Prepare TCP for device-to-device data transfers, by making sure
that payloads are always attached to skbs as page frags.
- Make the backoff time for the first N TCP SYN retransmissions
linear. Exponential backoff is unnecessarily conservative.
- Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO).
- Avoid waking up applications using TLS sockets until we have
a full record.
- Allow using kernel memory for protocol ioctl callbacks, paving
the way to issuing ioctls over io_uring.
- Add nolocalbypass option to VxLAN, forcing packets to be fully
encapsulated even if they are destined for a local IP address.
- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
in-kernel ECMP implementation (e.g. Open vSwitch) select the same
link for all packets. Support L4 symmetric hashing in Open vSwitch.
- PPPoE: make number of hash bits configurable.
- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
(ipconfig).
- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge).
- Support matching on Connectivity Fault Management (CFM) packets.
- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug.
- HSR: don't enable promiscuous mode if device offloads the proto.
- Support active scanning in IEEE 802.15.4.
- Continue work on Multi-Link Operation for WiFi 7.
BPF
---
- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used,
or in fact passing the verifier at all for complex programs,
especially those using open-coded iterators.
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what
the output buffer *should* be, without writing anything.
- Accept dynptr memory as memory arguments passed to helpers.
- Add routing table ID to bpf_fib_lookup BPF helper.
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands.
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only).
- Show target_{obj,btf}_id in tracing link fdinfo.
- Addition of several new kfuncs (most of the names are self-explanatory):
- Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
and bpf_dynptr_clone().
- bpf_task_under_cgroup()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter
---------
- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value.
- Increase ip_vs_conn_tab_bits range for 64BIT builds.
- Allow updating size of a set.
- Improve NAT tuple selection when connection is closing.
Driver API
----------
- Integrate netdev with LED subsystem, to allow configuring HW
"offloaded" blinking of LEDs based on link state and activity
(i.e. packets coming in and out).
- Support configuring rate selection pins of SFP modules.
- Factor Clause 73 auto-negotiation code out of the drivers, provide
common helper routines.
- Add more fool-proof helpers for managing lifetime of MDIO devices
associated with the PCS layer.
- Allow drivers to report advanced statistics related to Time Aware
scheduler offload (taprio).
- Allow opting out of VF statistics in link dump, to allow more VFs
to fit into the message.
- Split devlink instance and devlink port operations.
