net, neigh: Set lower cap for neigh_managed_work rearming
Yuwei reported that plain reuse of DELAY_PROBE_TIME to rearm work queue
in neigh_managed_work is problematic if user explicitly configures the
DELAY_PROBE_TIME to 0 for a neighbor table. Such misconfig can then hog
CPU to 100% processing the system work queue. Instead, set lower interval
bound to HZ which is totally sufficient. Yuwei is additionally looking
into making the interval separately configurable from DELAY_PROBE_TIME.

"Core
----
- Support TCPv6 segmentation offload with super-segments larger than
64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).
- Generalize skb freeing deferral to per-cpu lists, instead of
per-socket lists.
- Add a netdev statistic for packets dropped due to L2 address
mismatch (rx_otherhost_dropped).
- Continue work annotating skb drop reasons.
- Accept alternative netdev names (ALT_IFNAME) in more netlink
requests.
- Add VLAN support for AF_PACKET SOCK_RAW GSO.
- Allow receiving skb mark from the socket as a cmsg.
- Enable memcg accounting for veth queues, sysctl tables and IPv6.
BPF
---
- Add libbpf support for User Statically-Defined Tracing (USDTs).
- Speed up symbol resolution for kprobes multi-link attachments.
- Support storing typed pointers to referenced and unreferenced
objects in BPF maps.
- Add support for BPF link iterator.
- Introduce access to remote CPU map elements in BPF per-cpu map.
- Allow middle-of-the-road settings for the
kernel.unprivileged_bpf_disabled sysctl.
- Implement basic types of dynamic pointers e.g. to allow for
dynamically sized ringbuf reservations without extra memory copies.
Protocols
---------
- Retire port only listening_hash table, add a second bind table
hashed by port and address. Avoid linear list walk when binding to
very popular ports (e.g. 443).
- Add bridge FDB bulk flush filtering support allowing user space to
remove all FDB entries matching a condition.
- Introduce accept_unsolicited_na sysctl for IPv6 to implement
router-side changes for RFC9131.

- Offload writing printk() messages on consoles to per-console
kthreads.
It prevents soft-lockups when an extensive amount of messages is
printed. It was observed, for example, during boot of large systems
with a lot of peripherals like disks or network interfaces.
It prevents live-lockups that were observed, for example, when
messages about allocation failures were reported and a CPU handled
consoles instead of reclaiming the memory. It was hard to solve even
with rate limiting because it would need to take into account the
amount of messages and the speed of all consoles.
It is a must to have for real time. Otherwise, any printk() might
break latency guarantees.
The per-console kthreads allow to handle each console on its own
speed. Slow consoles do not longer slow down faster ones. And
printk() does not longer unpredictably slows down various code paths.
There are situations when the kthreads are either not available or
not reliable, for example, early boot, suspend, or panic. In these
situations, printk() uses the legacy mode and tries to handle
consoles immediately.

Commit
c724c866bb70 ("linux/types.h: remove unnecessary __bitwise__")
was right that there are no users of __bitwise__ in the kernel, but it
turns out there are user space users of it that do expect it.
It is, after all, in the uapi directory, so user space usage is to be
expected.
Instead of reverting the commit completely, let's just clarify the
situation so that it doesn't happen again, and have some in-code
explanations for why that "__bitwise__" still exists.

"There's a couple of corrections sent in by Andreas for some accounting
errors.
The biggest change this time around is that writeback errors longer
clear pageuptodate nor does XFS invalidate the page cache anymore.
This brings XFS (and gfs2/zonefs) behavior in line with every other
Linux filesystem driver, and fixes some UAF bugs that only cropped up
after willy turned on multipage folios for XFS in 5.18-rc1.
Regrettably, it took all the way to the end of the 5.18 cycle to find
the source of these bugs and reach a consensus that XFS' writeback
failure behavior from 20 years ago is no longer necessary.
Summary:
- Fix a couple of accounting errors in the buffered io code.
- Discontinue the practice of marking folios !uptodate and
invalidating them when writeback fails.

Pull erofs (and fscache) updates from Gao Xiang:
"After working on it on the mailing list for more than half a year, we
finally form 'erofs over fscache' feature into shape. Hopefully it
could bring more possibility to the communities.
The story mainly started from a new project what we called "RAFS v6" [1]
for Nydus image service almost a year ago, which enhances EROFS to be
a new form of one bootstrap (which includes metadata representing the
whole fs tree) + several data-deduplicated content addressable blobs
(actually treated as multiple devices). Each blob can represent one
container image layer but not quite exactly since all new data can be
fully existed in the previous blobs so no need to introduce another
new blob.
It is actually not a new idea (at least on my side it's much like a
simpilied casync [2] for now) and has many benefits over per-file
blobs or some other exist ways since typically each RAFS v6 image only
has dozens of device blobs instead of thousands of per-file blobs.
It's easy to be signed with user keys as a golden image, transfered
untouchedly with minimal overhead over the network, kept in some type
of storage conveniently, and run with (optional) runtime verification
but without involving too many irrelevant features crossing the system
beyond EROFS itself. At least it's our final goal and we're keeping
working on it. There was also a good summary of this approach from the
casync author [3].
Regardless further optimizations, this work is almost done in the
previous Linux release cycles. In this round, we'd like to introduce
on-demand load for EROFS with the fscache/cachefiles infrastructure,
considering the following advantages:
- Introduce new file-based backend to EROFS. Although each image only
contains dozens of blobs but in densely-deployed runC host for
example, there could still be massive blobs on a machine, which is
messy if each blob is treated as a device. In contrast, fscache and
cachefiles are really great interfaces for us to make them work.
- Introduce on-demand load to fscache and EROFS. Previously, fscache
is mainly used to caching network-likewise filesystems, now it can
support on-demand downloading for local fses too with the exact
localfs on-disk format. It has many advantages which we're been
described in the latest patchset cover letter [4]. In addition to
that, most importantly, the cached data is still stored in the
original local fs on-disk format so that it's still the one signed
with private keys but only could be partially available. Users can
fully trust it during running. Later, users can also back up
cachefiles easily to another machine.
- More reliable on-demand approach in principle. After data is all
available locally, user daemon can be no longer online in some use
cases, which helps daemon crash recovery (filesystems can still in
service) and hot-upgrade (user daemon can be upgraded more
frequently due to new features or protocols introduced.)
- Other format can also be converted to EROFS filesystem format over
the internet on the fly with the new on-demand load feature and
mounted. That is entirely possible with on-demand load feature as
long as such archive format metadata can be fetched in advance like
stargz.
In addition, although currently our target user is Nydus image service [5],
but laterly, it can be used for other use cases like on-demand system
booting, etc. As for the fscache on-demand load feature itself,
strictly it can be used for other local fses too. Laterly we could
promote most code to the iomap infrastructure and also enhance it in
the read-write way if other local fses are interested.
Thanks David Howells for taking so much time and patience on this
these months, many thanks with great respect here again! Thanks Jeffle
for working on this feature and Xin Yin from Bytedance for
asynchronous I/O implementation as well as Zichen Tian, Jia Zhu, and
Yan Song for testing, much appeciated. We're also exploring more
possibly over fscache cache management over FSDAX for secure
containers and working on more improvements and useful features for
fscache, cachefiles, and on-demand load.
In addition to "erofs over fscache", NFS export and idmapped mount are
also completed in this cycle for container use cases as well.
Summary:
- Add erofs on-demand load support over fscache
- Support NFS export for erofs
- Support idmapped mounts for erofs
- Don't prompt for risk any more when using big pcluster
- Fix buffer copy overflow of ztailpacking feature
- Several minor cleanups"

"This contains two minor updates:
- An update to the idmapping documentation by Rodrigo making it
easier to understand that we first introduce several use-cases that
fail without idmapped mounts simply to explain how they can be
handled with idmapped mounts.
- When changing a mount's idmapping we now hold writers to make it
more robust.
This is similar to turning a mount ro with the difference that in
contrast to turning a mount ro changing the idmapping can only ever
be done once while a mount can transition between ro and rw as much
as it wants.
The vfs layer itself takes care to retrieve the idmapping of a
mount once ensuring that the idmapping used for vfs permission
checking is identical to the idmapping passed down to the
filesystem. All filesystems with FS_ALLOW_IDMAP raised take the
same precautions as the vfs in code-paths that are outside of
direct control of the vfs such as ioctl()s.
However, holding writers makes this more robust and predictable for
both the kernel and userspace.
This is a minor user-visible change. But it is extremely unlikely
to matter. The caller must've created a detached mount via
OPEN_TREE_CLONE and then handed that O_PATH fd to another process
or thread which then must've gotten a writable fd for that mount
and started creating files in there while the caller is still
changing mount properties. While not impossible it will be an
extremely rare corner-case and should in general be considered a
bug in the application. Consider making a mount MOUNT_ATTR_NOEXEC
or MOUNT_ATTR_NODEV while allowing someone else to perform lookups
or exec'ing in parallel by handing them a copy of the
OPEN_TREE_CLONE fd or another fd beneath that mount.
I've pinged all major users of idmapped mounts pointing out this
change and none of them have active writers on a mount while still
changing mount properties. It would've been strange if they did.
The rest and majority of the work will be coming through the overlayfs
tree this cycle. In addition to overlayfs this cycle should also see
support for idmapped mounts on erofs as I've acked a patch to this
effect a little while ago"

ext4: only allow test_dummy_encryption when supported
Make the test_dummy_encryption mount option require that the encrypt
feature flag be already enabled on the filesystem, rather than
automatically enabling it. Practically, this means that "-O encrypt"
will need to be included in MKFS_OPTIONS when running xfstests with the
test_dummy_encryption mount option. (ext4/053 also needs an update.)
Moreover, as long as the preconditions for test_dummy_encryption are
being tightened anyway, take the opportunity to start rejecting it when
!CONFIG_FS_ENCRYPTION rather than ignoring it.
The motivation for requiring the encrypt feature flag is that:
- Having the filesystem auto-enable feature flags is problematic, as it
bypasses the usual sanity checks. The specific issue which came up
recently is that in kernel versions where ext4 supports casefold but
not encrypt+casefold (v5.1 through v5.10), the kernel will happily add
the encrypt flag to a filesystem that has the casefold flag, making it
unmountable -- but only for subsequent mounts, not the initial one.
This confused the casefold support detection in xfstests, causing
generic/556 to fail rather than be skipped.
- The xfstests-bld test runners (kvm-xfstests et al.) already use the
required mkfs flag, so they will not be affected by this change. Only
users of test_dummy_encryption alone will be affected. But, this
option has always been for testing only, so it should be fine to
require that the few users of this option update their test scripts.
- f2fs already requires it (for its equivalent feature flag).

In the ext4_valid_extent_entries function,
if prev is 0, no error is returned even if lblock<=prev.
This was intended to skip the check on the first extent, but
in the error image above, prev=0+1-1=0 when checking the second extent,
so even though lblock<=prev, the function does not return an error.
As a result, bug_ON occurs in __es_tree_search and the system panics.
To solve this problem, we only need to check that:
1. The lblock of the first extent is not less than 0.
2. The lblock of the next extent is not less than
the next block of the previous extent.
The same applies to extent_idx.

ext4: filter out EXT4_FC_REPLAY from on-disk superblock field s_state
The EXT4_FC_REPLAY bit in sbi->s_mount_state is used to indicate that
we are in the middle of replay the fast commit journal. This was
actually a mistake, since the sbi->s_mount_info is initialized from
es->s_state. Arguably s_mount_state is misleadingly named, but the
name is historical --- s_mount_state and s_state dates back to ext2.
What should have been used is the ext4_{set,clear,test}_mount_flag()
inline functions, which sets EXT4_MF_* bits in sbi->s_mount_flags.
The problem with using EXT4_FC_REPLAY is that a maliciously corrupted
superblock could result in EXT4_FC_REPLAY getting set in
s_mount_state. This bypasses some sanity checks, and this can trigger
a BUG() in ext4_es_cache_extent(). As a easy-to-backport-fix, filter
out the EXT4_FC_REPLAY bit for now. We should eventually transition
away from EXT4_FC_REPLAY to something like EXT4_MF_REPLAY.

gfs2: Return more useful errors from gfs2_rgrp_send_discards()
The bug that
27ca8273f ("gfs2: Make sure FITRIM minlen is rounded up to

"Input/output error" which masked the -EINVAL that sb_issue_discard()
returned.
sb_issue_discard() can fail for various reasons, so we should return its
return value from gfs2_rgrp_send_discards() to avoid all errors being
reported as IO errors.
This improves error reporting for FITRIM and makes no difference to the
-o discard code path because the return value from
gfs2_rgrp_send_discards() gets thrown away in that case (and the option
switches off). Presumably that's why it was ok to just return -EIO in
the past, before FITRIM was implemented.

Pull random number generator updates from Jason Donenfeld:
"These updates continue to refine the work began in 5.17 and 5.18 of
modernizing the RNG's crypto and streamlining and documenting its
code.
New for 5.19, the updates aim to improve entropy collection methods
and make some initial decisions regarding the "premature next" problem
and our threat model. The cloc utility now reports that random.c is
931 lines of code and 466 lines of comments, not that basic metrics
like that mean all that much, but at the very least it tells you that
this is very much a manageable driver now.
Here's a summary of the various updates:
- The random_get_entropy() function now always returns something at
least minimally useful. This is the primary entropy source in most
collectors, which in the best case expands to something like RDTSC,
but prior to this change, in the worst case it would just return 0,
contributing nothing. For 5.19, additional architectures are wired
up, and architectures that are entirely missing a cycle counter now
have a generic fallback path, which uses the highest resolution
clock available from the timekeeping subsystem.
Some of those clocks can actually be quite good, despite the CPU
not having a cycle counter of its own, and going off-core for a
stamp is generally thought to increase jitter, something positive
from the perspective of entropy gathering. Done very early on in
the development cycle, this has been sitting in next getting some
testing for a while now and has relevant acks from the archs, so it
should be pretty well tested and fine, but is nonetheless the thing
I'll be keeping my eye on most closely.
- Of particular note with the random_get_entropy() improvements is
MIPS, which, on CPUs that lack the c0 count register, will now
combine the high-speed but short-cycle c0 random register with the
lower-speed but long-cycle generic fallback path.
- With random_get_entropy() now always returning something useful,
the interrupt handler now collects entropy in a consistent
construction.
- Rather than comparing two samples of random_get_entropy() for the
jitter dance, the algorithm now tests many samples, and uses the
amount of differing ones to determine whether or not jitter entropy
is usable and how laborious it must be. The problem with comparing
only two samples was that if the cycle counter was extremely slow,
but just so happened to be on the cusp of a change, the slowness
wouldn't be detected. Taking many samples fixes that to some
degree.
This, combined with the other improvements to random_get_entropy(),
should make future unification of /dev/random and /dev/urandom
maybe more possible. At the very least, were we to attempt it again
today (we're not), it wouldn't break any of Guenter's test rigs
that broke when we tried it with 5.18. So, not today, but perhaps
down the road, that's something we can revisit.
- We attempt to reseed the RNG immediately upon waking up from system
suspend or hibernation, making use of the various timestamps about
suspend time and such available, as well as the usual inputs such
as RDRAND when available.
- Batched randomness now falls back to ordinary randomness before the
RNG is initialized. This provides more consistent guarantees to the
types of random numbers being returned by the various accessors.
- The "pre-init injection" code is now gone for good. I suspect you
in particular will be happy to read that, as I recall you
expressing your distaste for it a few months ago. Instead, to avoid
a "premature first" issue, while still allowing for maximal amount
of entropy availability during system boot, the first 128 bits of
estimated entropy are used immediately as it arrives, with the next
128 bits being buffered. And, as before, after the RNG has been
fully initialized, it winds up reseeding anyway a few seconds later
in most cases. This resulted in a pretty big simplification of the
initialization code and let us remove various ad-hoc mechanisms
like the ugly crng_pre_init_inject().
- The RNG no longer pretends to handle the "premature next" security
model, something that various academics and other RNG designs have
tried to care about in the past. After an interesting mailing list
thread, these issues are thought to be a) mainly academic and not
practical at all, and b) actively harming the real security of the
RNG by delaying new entropy additions after a potential compromise,
making a potentially bad situation even worse. As well, in the
first place, our RNG never even properly handled the premature next
issue, so removing an incomplete solution to a fake problem was
particularly nice.
This allowed for numerous other simplifications in the code, which
is a lot cleaner as a consequence. If you didn't see it before,
https://lore.kernel.org/lkml/YmlMGx6+uigkGiZ0@zx2c4.com/ may be a
thread worth skimming through.
- While the interrupt handler received a separate code path years ago
that avoids locks by using per-cpu data structures and a faster
mixing algorithm, in order to reduce interrupt latency, input and
disk events that are triggered in hardirq handlers were still
hitting locks and more expensive algorithms. Those are now
redirected to use the faster per-cpu data structures.
- Rather than having the fake-crypto almost-siphash-based random32
implementation be used right and left, and in many places where
cryptographically secure randomness is desirable, the batched
entropy code is now fast enough to replace that.
- As usual, numerous code quality and documentation cleanups. For
example, the initialization state machine now uses enum symbolic
constants instead of just hard coding numbers everywhere.
- Since the RNG initializes once, and then is always initialized
thereafter, a pretty heavy amount of code used during that
initialization is never used again. It is now completely cordoned
off using static branches and it winds up in the .text.unlikely
section so that it doesn't reduce cache compactness after the RNG
is ready.
- A variety of functions meant for waiting on the RNG to be
initialized were only used by vsprintf, and in not a particularly
optimal way. Replacing that usage with a more ordinary setup made
it possible to remove those functions.
- A cleanup of how we warn userspace about the use of uninitialized
/dev/urandom and uninitialized get_random_bytes() usage.
Interestingly, with the change you merged for 5.18 that attempts to
use jitter (but does not block if it can't), the majority of users
should never see those warnings for /dev/urandom at all now, and
the one for in-kernel usage is mainly a debug thing.
- The file_operations struct for /dev/[u]random now implements
.read_iter and .write_iter instead of .read and .write, allowing it
to also implement .splice_read and .splice_write, which makes
splice(2) work again after it was broken here (and in many other
places in the tree) during the set_fs() removal. This was a bit of
a last minute arrival from Jens that hasn't had as much time to
bake, so I'll be keeping my eye on this as well, but it seems
fairly ordinary. Unfortunately, read_iter() is around 3% slower
than read() in my tests, which I'm not thrilled about. But Jens and
Al, spurred by this observation, seem to be making progress in
removing the bottlenecks on the iter paths in the VFS layer in
general, which should remove the performance gap for all drivers.
- Assorted other bug fixes, cleanups, and optimizations.
- A small SipHash cleanup"

lockdown: also lock down previous kgdb use
KGDB and KDB allow read and write access to kernel memory, and thus
should be restricted during lockdown. An attacker with access to a
serial port (for example, via a hypervisor console, which some cloud
vendors provide over the network) could trigger the debugger so it is
important that the debugger respect the lockdown mode when/if it is
triggered.
Fix this by integrating lockdown into kdb's existing permissions
mechanism. Unfortunately kgdb does not have any permissions mechanism
(although it certainly could be added later) so, for now, kgdb is simply
and brutally disabled by immediately exiting the gdb stub without taking
any action.
For lockdowns established early in the boot (e.g. the normal case) then
this should be fine but on systems where kgdb has set breakpoints before
the lockdown is enacted than "bad things" will happen.

- Comprehensive interface overhaul:
=================================
Objtool's interface has some issues:
- Several features are done unconditionally, without any way to
turn them off. Some of them might be surprising. This makes
objtool tricky to use, and prevents porting individual features
to other arches.
- The config dependencies are too coarse-grained. Objtool
enablement is tied to CONFIG_STACK_VALIDATION, but it has several
other features independent of that.
- The objtool subcmds ("check" and "orc") are clumsy: "check" is
really a subset of "orc", so it has all the same options.
The subcmd model has never really worked for objtool, as it only
has a single purpose: "do some combination of things on an object
file".
- The '--lto' and '--vmlinux' options are nonsensical and have
surprising behavior.
Overhaul the interface:
- get rid of subcmds
- make all features individually selectable
- remove and/or clarify confusing/obsolete options
- update the documentation
- fix some bugs found along the way
- Fix x32 regression
- Fix Kbuild cleanup bugs
- Add scripts/objdump-func helper script to disassemble a single

- Rewrite scripts/faddr2line to be section-aware, by basing it on

zonefs: Fix zonefs_init_file_inode() return value
Commit
87c9ce3ffec9 ("zonefs: Add active seq file accounting") wrongly
changed zonefs_init_file_inode() to always return 0 even if the call to
zonefs_zone_mgmt() fails. Fix this by propagating zonefs_zone_mgmt()

monitoring coherent I/O traffic, support for Arm's CMN-650 and
CMN-700 interconnect PMUs, minor driver fixes, kerneldoc cleanup.
- Kselftest updates for SME, BTI, MTE.
- Automatic generation of the system register macros from a 'sysreg'
file describing the register bitfields.
- Update the type of the function argument holding the ESR_ELx register
value to unsigned long to match the architecture register size
(originally 32-bit but extended since ARMv8.0).

- ftrace cleanups.
- Miscellaneous updates, most notably: arm64-specific huge_ptep_get(),
avoid executable mappings in kexec/hibernate code, drop TLB flushing
from get_clear_flush() (and rename it to get_clear_contig()),
ARCH_NR_GPIO bumped to 2048 for ARCH_APPLE.

"A set of patches to prevent crashes in SGX enclaves under heavy memory
pressure:
SGX uses normal RAM allocated from special shmem files as backing

aggressive when freeing shmem pages and was inadvertently freeing
perfectly good data. This resulted in failures in the SGX instructions
used to swap data back into SGX memory.
This turned out to be really hard to trigger in mainline. It was
originally encountered testing the out-of-tree "SGX2" patches, but
later reproduced on mainline.
Fix the data loss by being more careful about truncating pages out of
the backing storage and more judiciously setting pages dirty"
