[ Upstream commit 2951580ba6adb082bb6b7154a5ecb24e7c1f7569 ]
The trace output for the HRTIMER_MODE_.*_HARD modes is seen as a number
since these modes are not decoded. The author was not aware of the fancy
decoding function which makes the life easier.
Extend decode_hrtimer_mode() with the additional HRTIMER_MODE_.*_HARD
modes.

When commit 19343b5bdd16 ("mm/page-writeback: introduce tracepoint for
wait_on_page_writeback()") repurposed the writeback_dirty_page trace event
as a template to create its new wait_on_page_writeback trace event, it
ended up opening a window to NULL pointer dereference crashes due to the
(infrequent) occurrence of a race where an access to a page in the
swap-cache happens concurrently with the moment this page is being written
to disk and the tracepoint is enabled:

This problem arises from the fact that the repurposed writeback_dirty_page
trace event code was written assuming that every pointer to mapping
(struct address_space) would come from a file-mapped page-cache object,
thus mapping->host would always be populated, and that was a valid case
before commit 19343b5bdd16. The swap-cache address space
(swapper_spaces), however, doesn't populate its ->host (struct inode)
pointer, thus leading to the crashes in the corner-case aforementioned.
commit 19343b5bdd16 ended up breaking the assignment of __entry->name and
__entry->ino for the wait_on_page_writeback tracepoint -- both dependent
on mapping->host carrying a pointer to a valid inode. The assignment of
__entry->name was fixed by commit 68f23b89067f ("memcg: fix a crash in
wb_workfn when a device disappears"), and this commit fixes the remaining
case, for __entry->ino.

Pull nfsd updates from Chuck Lever:
"The big ticket item for this release is that support for RPC-with-TLS
[RFC 9289] has been added to the Linux NFS server.
The goal is to provide a simple-to-deploy, low-overhead in-transit
confidentiality and peer authentication mechanism. It can supplement
NFS Kerberos and it can protect the use of legacy non-cryptographic
user authentication flavors such as AUTH_SYS. The TLS Record protocol
is handled entirely by kTLS, meaning it can use either software
encryption or offload encryption to smart NICs.
Aside from that, work continues on improving NFSD's open file cache.
Among the many clean-ups in that area is a patch to convert the
rhashtable to use the list-hashing version of that data structure"

This patch adds opportunitistic RPC-with-TLS to the Linux in-kernel
NFS server. If the client requests RPC-with-TLS and the user space
handshake agent is running, the server will set up a TLS session.
There are no policy settings yet. For example, the server cannot
yet require the use of RPC-with-TLS to access its data.

Pull networking updates from Paolo Abeni:
"Core:
- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
default value allows for better BIG TCP performances
- Reduce compound page head access for zero-copy data transfers
- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when
possible
- Threaded NAPI improvements, adding defer skb free support and
unneeded softirq avoidance
- Address dst_entry reference count scalability issues, via false
sharing avoidance and optimize refcount tracking
- Add lockless accesses annotation to sk_err[_soft]
- Optimize again the skb struct layout
- Extends the skb drop reasons to make it usable by multiple
subsystems
- Better const qualifier awareness for socket casts
BPF:
- Add skb and XDP typed dynptrs which allow BPF programs for more
ergonomic and less brittle iteration through data and
variable-sized accesses
- Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward
- Add more precise memory usage reporting for all BPF map types
- Adds support for using {FOU,GUE} encap with an ipip device
operating in collect_md mode and add a set of BPF kfuncs for
controlling encap params
- Allow BPF programs to detect at load time whether a particular
kfunc exists or not, and also add support for this in light
skeleton
- Bigger batch of BPF verifier improvements to prepare for upcoming
BPF open-coded iterators allowing for less restrictive looping
capabilities
- Rework RCU enforcement in the verifier, add kptr_rcu and enforce
BPF programs to NULL-check before passing such pointers into kfunc
- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and
in local storage maps
- Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps
- Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree
- Add BPF verifier support for ST instructions in
convert_ctx_access() which will help new -mcpu=v4 clang flag to
start emitting them
- Add ARM32 USDT support to libbpf
- Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations
Protocols:
- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
indicates the provenance of the IP address
- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition
- Add the handshake upcall mechanism, allowing the user-space to
implement generic TLS handshake on kernel's behalf
- Bridge: support per-{Port, VLAN} neighbor suppression, increasing
resilience to nodes failures
- SCTP: add support for Fair Capacity and Weighted Fair Queueing
schedulers
- MPTCP: delay first subflow allocation up to its first usage. This
will allow for later better LSM interaction
- xfrm: Remove inner/outer modes from input/output path. These are
not needed anymore
- WiFi:
- reduced neighbor report (RNR) handling for AP mode
- HW timestamping support

- per-link debugfs for multi-link
- TC offload support for mac80211 drivers
- mac80211 mesh fast-xmit and fast-rx support

Netfilter:
- Add nf_tables 'brouting' support, to force a packet to be routed
instead of being bridged
- Update bridge netfilter and ovs conntrack helpers to handle IPv6
Jumbo packets properly, i.e. fetch the packet length from
hop-by-hop extension header. This is needed for BIT TCP support
- The iptables 32bit compat interface isn't compiled in by default
anymore
- Move ip(6)tables builtin icmp matches to the udptcp one. This has
the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used
- Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device
Driver API:
- Remove redundant Device Control Error Reporting Enable, as PCI core
has already error reporting enabled at enumeration time
- Move Multicast DB netlink handlers to core, allowing devices other
then bridge to use them
- Allow the page_pool to directly recycle the pages from safely
localized NAPI

further code de-duplication and sanitization
- Add YNL support for user headers and struct attrs
- Add partial YNL specification for devlink
- Add partial YNL specification for ethtool

of bytes of a transmitted packet a driver can push directly to the
underlying device
- Add basic LED support for switch/phy
- Add NAPI documentation, stop relaying on external links
- Convert dsa_master_ioctl() to netdev notifier. This is a

Pull io_uring updates from Jens Axboe:
- Cleanup of the io-wq per-node mapping, notably getting rid of it so
we just have a single io_wq entry per ring (Breno)
- Followup to the above, move accounting to io_wq as well and
completely drop struct io_wqe (Gabriel)
- Enable KASAN for the internal io_uring caches (Breno)
- Add support for multishot timeouts. Some applications use timeouts to
wake someone waiting on completion entries, and this makes it a bit
easier to just have a recurring timer rather than needing to rearm it
every time (David)
- Support archs that have shared cache coloring between userspace and
the kernel, and hence have strict address requirements for mmap'ing
the ring into userspace. This should only be parisc/hppa. (Helge, me)
- XFS has supported O_DIRECT writes without needing to lock the inode
exclusively for a long time, and ext4 now supports it as well. This
is true for the common cases of not extending the file size. Flag the
fs as having that feature, and utilize that to avoid serializing
those writes in io_uring (me)
- Enable completion batching for uring commands (me)
- Revert patch adding io_uring restriction to what can be GUP mapped or
not. This does not belong in io_uring, as io_uring isn't really
special in this regard. Since this is also getting in the way of
cleanups and improvements to the GUP code, get rid of if (me)
- A few series greatly reducing the complexity of registered resources,
like buffers or files. Not only does this clean up the code a lot,
the simplified code is also a LOT more efficient (Pavel)

it (Pavel)

Pull btrfs updates from David Sterba:
"Mostly core changes and cleanups, some notable fixes and two
performance improvements in directory logging.
The IO path cleanups are removing or refactoring old code, scrub main
loop has been completely rewritten also refactoring old code.
There are some changes to non-btrfs code, mostly trivial, the cgroup
punt bio logic is only moved from generic code.
Performance improvements:
- improve logging changes in a directory during one transaction,
avoid iterating over items and reduce lock contention (fsync time
4x lower)
- when logging directory entries during one transaction, reduce
locking of subvolume trees by checking tree-log instead
(improvement in throughput and latency for concurrent access to a
subvolume)
Notable fixes:
- dev-replace:
- properly honor read mode when requested to avoid reading from
source device
- target device won't be used for eventual read repair, this is
unreliable for NODATASUM files
- when there are unpaired (and unrepairable) metadata during
replace, exit early with error and don't try to finish whole
operation
- scrub ioctl properly rejects unknown flags
- fix global block reserve calculations
- fix partial direct io write when there's a page fault in the
middle, iomap will try to continue with partial request but the
btrfs part did not match that, this can lead to zeros written
instead of data
Core changes:
- io path:
- continued cleanups and refactoring around bio handling
- extent io submit path simplifications and cleanups
- flush write path simplifications and cleanups
- rework logic of passing sync mode of bio, with further cleanups
- rewrite scrub code flow, restructure how the stripes are enumerated
and verified in a more unified way
- allow to set lower threshold for block group reclaim in debug mode
to aid zoned mode testing
- remove obsolete time-based delayed ref throttling logic when
truncating items
- DREW locks are not using percpu variables anymore
- more warning fixes (-Wmaybe-uninitialized)
- u64 division simplifications
- error handling improvements
Non-btrfs code changes:
- push cgroup punt bio logic to btrfs code (there was no other user
of that), the functionality can be now selected separately by
BLK_CGROUP_PUNT_BIO
- crc32c_impl removed after removing last uses in btrfs code
- add btrfs_assertfail() to objtool table"

There have been several bugs over the years where the NFSD splice
actor has attempted to write outside the rq_pages array.
This is a "should never happen" condition, but if for some reason
the pipe splice actor should attempt to walk past the end of
rq_pages, it needs to terminate the READ operation to prevent
corruption of the pointer addresses in the fields just beyond the
array.
A server crash is thus prevented. Since the code is not behaving,
the READ operation returns -EIO to the client. None of the READ
payload data can be trusted if the splice actor isn't operating as
expected.

Pull erofs updates from Gao Xiang:
"In this cycle, sub-page block support for uncompressed files is
available. It's mainly used to enable original signing ('golden')
4k-block images on arm64 with 16/64k pages. In addition, end users
could also use this feature to build a manifest to directly refer to
golden tar data.
Besides, long xattr name prefix support is also introduced in this
cycle to avoid too many xattrs with the same prefix (e.g. overlayfs
xattrs). It's useful for erofs + overlayfs combination (like Composefs
model): the image size is reduced by ~14% and runtime performance is
also slightly improved.
Others are random fixes and cleanups as usual.
Summary:
- Add sub-page block size support for uncompressed files
- Support flattened block device for multi-blob images to be attached
