The root cause is after commit 84b5bb8bf0f6 ("f2fs: modify
f2fs_is_checkpoint_ready logic to allow more data to be written with the
CP disable"), we will get chance to allow f2fs_is_checkpoint_ready() to
return true once below conditions are all true:
1. checkpoint is disabled
2. there are not enough free segments
3. there are enough free blocks
Then it will cause f2fs_balance_fs() to trigger foreground GC.
void f2fs_balance_fs(struct f2fs_sb_info *sbi, bool need)
...
if (!f2fs_is_checkpoint_ready(sbi))
return;
And the testcase mounts f2fs image w/ gc_merge,checkpoint=disable, so deadloop
will happen through below race condition:
- f2fs_do_shutdown - vfs_fallocate - gc_thread_func
- file_start_write
- __sb_start_write(SB_FREEZE_WRITE)
- f2fs_fallocate
- f2fs_expand_inode_data
- f2fs_map_blocks
- f2fs_balance_fs
- prepare_to_wait
- wake_up(gc_wait_queue_head)
- io_schedule
- bdev_freeze
- freeze_super
- sb->s_writers.frozen = SB_FREEZE_WRITE;
- sb_wait_write(sb, SB_FREEZE_WRITE);
- if (sbi->sb->s_writers.frozen >= SB_FREEZE_WRITE) continue;
: cause deadloop
This patch fix to add check condition in f2fs_balance_fs(), so that if
checkpoint is disabled, we will just skip trigger foreground GC to
avoid such deadloop issue.
Meanwhile let's remove f2fs_is_checkpoint_ready() check condition in
f2fs_balance_fs(), since it's redundant, due to the main logic in the
function is to check:
a) whether checkpoint is disabled
b) there is enough free segments
f2fs_balance_fs() still has all logics after f2fs_is_checkpoint_ready()'s
removal.

when performing buffered writes in a large section,
overhead is incurred due to the iteration through
ckpt_valid_blocks within the section.
when SEGS_PER_SEC is 128, this overhead accounts for 20% within
the f2fs_write_single_data_page routine.
as the size of the section increases, the overhead also grows.
to handle this problem ckpt_valid_blocks is
added within the section entries.

Pull audit updates from Paul Moore:
- Always record AUDIT_ANOM events when auditing is enabled.
Prior to this patch we only recorded AUDIT_ANOM events if auditing
was enabled and the admin/distro had explicitly configured audit
beyond the defaults. Considering that AUDIT_ANOM events are anomolous
events considered to be "security relevant", it seems wise to record
these events as long as auditing is enabled, even if the system is
running with a default audit configuration.
- Mark the audit_log_vformat() function with the __printf() attribute
to quiet GCC.

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull selinux updates from Paul Moore:
- Reduce the SELinux impact on path walks.
Add a small directory access cache to the per-task SELinux state.
This cache allows SELinux to cache the most recently used directory
access decisions in order to avoid repeatedly querying the AVC on
path walks where the majority of the directories have similar
security contexts/labels.
My performance measurements are crude, but prior to this patch the
time spent in SELinux code on a 'make allmodconfig' run was 103% that
of __d_lookup_rcu(), and with this patch the time spent in SELinux
code dropped to 63% of __d_lookup_rcu(), a ~40% improvement.
Additional improvments can be expected in the future, but those will
require additional SELinux policy/toolchain support.
- Add support for wildcards in genfscon policy statements.
This patch allows for wildcards in the genfscon patch matching logic
as opposed to the prefix matching that was used prior to this change.
Adding wilcard support allows for more expressive and efficient path
matching in the policy which is especially helpful for sysfs, and has
resulted in a ~15% boot time reduction in Android.
SELinux policies can opt into wilcard matching by using the
"genfs_seclabel_wildcard" policy capability.
- Unify the error/OOM handling of the SELinux network caches.
A failure to allocate memory for the SELinux network caches isn't
fatal as the object label can still be safely returned to the caller,
it simply means that we cannot add the new data to the cache, at
least temporarily. This patch corrects this behavior for the
InfiniBand cache and does some minor cleanup.
- Minor improvements around constification, 'likely' annotations, and
removal of bogus comments.

Pull integrity updates from Mimi Zohar:
"Carrying the IMA measurement list across kexec is not a new feature,
but is updated to address a couple of issues:
- Carrying the IMA measurement list across kexec required knowing
apriori all the file measurements between the "kexec load" and
"kexec execute" in order to measure them before the "kexec load".
Any delay between the "kexec load" and "kexec exec" exacerbated the
problem.
- Any file measurements post "kexec load" were not carried across
kexec, resulting in the measurement list being out of sync with the
TPM PCR.
With these changes, the buffer for the IMA measurement list is still
allocated at "kexec load", but copying the IMA measurement list is
deferred to after quiescing the TPM.
Two new kexec critical data records are defined"

We have noticed that when PHY timestamping is enabled, L2 frames seems
to be modified by changing two 2 bytes with a value of 0. The place were
these 2 bytes seems to be random(or I couldn't find a pattern). In most
of the cases the userspace can ignore these frames but if for example
those 2 bytes are in the correction field there is nothing to do. This
seems to happen when configuring the HW for IPv4 even that the flow is
not enabled.
These 2 bytes correspond to the UDPv4 checksum and once we don't enable
clearing the checksum when using L2 frames then the frame doesn't seem
to be changed anymore.

syzkaller reported a null-ptr-deref in txopt_get(). [0]
The offset 0x70 was of struct ipv6_txoptions in struct ipv6_pinfo,
so struct ipv6_pinfo was NULL there.
However, this never happens for IPv6 sockets as inet_sk(sk)->pinet6
is always set in inet6_create(), meaning the socket was not IPv6 one.
The root cause is missing validation in netlbl_conn_setattr().
netlbl_conn_setattr() switches branches based on struct
sockaddr.sa_family, which is passed from userspace. However,
netlbl_conn_setattr() does not check if the address family matches
the socket.
The syzkaller must have called connect() for an IPv6 address on
an IPv4 socket.
We have a proper validation in tcp_v[46]_connect(), but
security_socket_connect() is called in the earlier stage.
Let's copy the validation to netlbl_conn_setattr().

net_sched: hfsc: Address reentrant enqueue adding class to eltree twice
Savino says:
"We are writing to report that this recent patch
(141d34391abbb315d68556b7c67ad97885407547)
can be bypassed, and a UAF can still occur when HFSC is utilized with
NETEM.
The patch only checks the cl->cl_nactive field to determine whether
it is the first insertion or not, but this field is only
incremented by init_vf.
By using HFSC_RSC (which uses init_ed), it is possible to bypass the
check and insert the class twice in the eltree.
Under normal conditions, this would lead to an infinite loop in
hfsc_dequeue for the reasons we already explained in this report.
However, if TBF is added as root qdisc and it is configured with a
very low rate,
it can be utilized to prevent packets from being dequeued.
This behavior can be exploited to perform subsequent insertions in the
HFSC eltree and cause a UAF."
To fix both the UAF and the infinite loop, with netem as an hfsc child,
check explicitly in hfsc_enqueue whether the class is already in the eltree
whenever the HFSC_RSC flag is set.
Also add a TDC test to reproduce the UAF scenario.

enqueue behaviour on netem
Reproduce the UAF scenario where netem is a child of HFSC and HFSC
is configured to use the eltree. In such case, this TDC test would
cause the HFSC class to be added to the eltree twice resulting
in a UAF.

This patch addresses below issues,
1. Active traffic on the leaf node must be stopped before its send queue
is reassigned to the parent. This patch resolves the issue by marking
the node as 'Inner'.
2. During a system reboot, the interface receives TC_HTB_LEAF_DEL
and TC_HTB_LEAF_DEL_LAST callbacks to delete its HTB queues.
In the case of TC_HTB_LEAF_DEL_LAST, although the same send queue
is reassigned to the parent, the current logic still attempts to update
the real number of queues, leadning to below warnings
New queues can't be registered after device unregistration.

is created, ensuring proper shaping and scheduling. However,
when multiple send queues are created and deleted in a loop,
SMMU errors are observed.

- More in-kernel idle CPU selection improvements. Expand topology
awareness coverage add scx_bpf_select_cpu_and() to allow more
flexibility. The idle CPU selection kfuncs can now be called from
unlocked contexts too.
- A bunch of reorganization changes to lay the foundation for multiple
hierarchical scheduler support. This isn't ready yet and the included
changes don't make meaningful behavior differences. One notable
change is replacing some static_key tests with dynamic tests as the
test results may differ depending on the scheduler instance. This
isn't expected to cause meaningful performance difference.
- Other minor and doc updates.

changes in for-6.16. for-6.15-fixes were pulled three times into
for-6.16 to resolve the conflicts.

Pull cgroup updates from Tejun Heo:
- cgroup rstat shared the tracking tree across all controllers with the
rationale being that a cgroup which is using one resource is likely
to be using other resources at the same time (ie. if something is
allocating memory, it's probably consuming CPU cycles).
However, this turned out to not scale very well especially with memcg
using rstat for internal operations which made memcg stat read and
flush patterns substantially different from other controllers. JP
Kobryn split the rstat tree per controller.
- cgroup BPF support was hooking into cgroup init/exit paths directly.
Convert them to use a notifier chain instead so that other usages can
be added easily. The two of the patches which implement this are
mislabeled as belonging to sched_ext instead of cgroup. Sorry.

The current test just sends "hello\nworld" and verifies that is the
string received on the RX side. That is fine, but improve the test a bit
by sending 1K data. The test should be improved further to send more
data, but for now this should be a welcome improvement.
The test will send a repeating pattern of 0x01, 0x02, ... 0x06. The
ncdevmem `-v 7` flag will verify this pattern. ncdevmem will provide
useful debugging info when the test fails, such as the frags received
and verified fine, and which frag exactly failed, what was the expected
byte pattern, and what is the actual byte pattern received. All this
debug information will be useful when the test fails.

Paolo Abeni says:
Recently the nipa CI infra went through some tuning, and the mentioned
self-test now often fails.
The failing test is the sctp+nfqueue one, where the file transfer takes
too long and hits the timeout (1 minute).
Because SCTP nfqueue tests had timeout related issues before (esp. on debug
kernels) print the file transfer duration in the PASS/FAIL message.
This would aallow us to see if there is/was an unexpected slowdown
(CI keeps logs around) or 'creeping slowdown' where things got slower
over time until 'fail point' was reached.
Output of altered lines looks like this:

Fix memory leak when running one-step timestamping. When running
one-step sync timestamping, the HW is configured to insert the TX time
into the frame, so there is no reason to keep the skb anymore. As in
this case the HW will never generate an interrupt to say that the frame
was timestamped, then the frame will never released.
Fix this by freeing the frame in case of one-step timestamping.

sctp_do_peeloff is only used inside of net/sctp/socket.c,
so mark it static.
