net: Introduce skb tc depth field to track packet loops
Add a 2-bit per-skb tc depth field to track packet loops across the stack. The previous per-CPU loop counters like MIRRED_NEST_LIMIT assume a single call stack and lose state in two cases: 1) When a packet is queued and reprocessed later (e.g., egress->ingress via backlog), the per-cpu state is gone by the time it is dequeued. 2) With XPS/RPS a packet may arrive on one CPU and be processed on another. A per-skb field solves both by travelling with the packet itself. The field fits in existing padding, using 2 bits that were previously a hole: pahole before(-) and after (+) diff looks like: __u8 slow_gro:1; /* 132: 3 1 */ __u8 csum_not_inet:1; /* 132: 4 1 */ __u8 unreadable:1; /* 132: 5 1 */ + __u8 tc_depth:2; /* 132: 6 1 */ - /* XXX 2 bits hole, try to pack */ /* XXX 1 byte hole, try to pack */ __u16 tc_index; /* 134 2 */ There used to be a ttl field which was removed as part of tc_verd in commit |

netfilter: nf_tables: fix dst corruption in same register operation
For lshift and rshift, the shift operations are performed in a loop over
32-bit words. The loop calculates the shifted value and write it to dst,
and then immediately reads from src to calculate the carry for the next
iteration. Because src and dst could point to the same memory location,
the carry is incorrectly calculated using the newly modified dst value
instead of the original src value.
Adding a temporary local variable to cache the original value before
writing to dst and using it for the carry calculation solves the
problem. In addition, partial overlap is rejected from control plane for
all kind of operations including byteorder. This was tested with the
following bytecode:
table test_table ip flags 0 use 1 handle 1
ip test_table test_chain use 3 type filter hook input prio 0 policy accept packets 0 bytes 0 flags 1
ip test_table test_chain 2
[ immediate reg 1 0x44332211 0x88776655 ]
[ bitwise reg 1 = ( reg 1 << 0x08000000 ) ]
[ cmp eq reg 1 0x66443322 0x00887766 ]
[ counter pkts 0 bytes 0 ]

netfilter: nf_conntrack_gre: fix gre keymap list corruption
Quoting reporter: A race between GRE keymap insertion and destruction can corrupt the kernel list or use a freed object. `nf_ct_gre_keymap_add()` publishes a new keymap pointer before the embedded `list_head` is linked, while `nf_ct_gre_keymap_destroy()` can concurrently delete and free that same object. An unprivileged user can reach this through the PPTP conntrack helper by racing PPTP control messages or helper teardown, leading to KASAN-detectable list corruption/UAF in kernel context. ## Root Cause Analysis `exp_gre()` installs GRE expectations for a PPTP control flow and then adds two GRE keymap entries [..] The add path publishes `ct_pptp_info->keymap[dir]` before linking the embedded list node [..] Concurrent teardown deletes that partially initialized object. Make add/destroy symmetric: install both, destroy both while under lock. Furthermore, we should refuse to publish a new mapping in case ct is going away, else we may leak the allocation. The "retrans" detection is strange: existing mapping is checked for key equality with the new mapping, then for "is on the list" via list walk. But I can't see how an existing keymap entry can be NOT on list. Change this to only check if we're asked to map same tuple again -- if so, skip re-install, else signal failure. Last, add a bug trap for the keymap list; it has to be empty when namespace is going away. Reported-by: Leo Lin <leo@depthfirst.com> Signed-off-by: Florian Westphal <fw@strlen.de> |

Craziness continues with no end in sight. Even discounting the driver

is that so far we haven't seen many (any?) cases of "AI reported a

ring-buffer fixes for 7.1:
- Fix reporting MISSED EVENTS in trace iterator When the "trace" file is read with tracing enabled, if the writer were to pass the iterator reader, it resets, sets a "missed_events" flag and continues. The tracing output checks for missed events and if there are some, it prints out "[LOST EVENTS]" to let the user know events were dropped. But the clearing of the missed_events happened when the tracing system queried the ring buffer iterator about missed events. This was premature as the ring buffer is per CPU, and the tracing code reads all the CPU buffers and checks for missed events when it is read. If the CPU iterator that had missed events isn't printed next, the output for the LOST EVENTS is lost. Clear the missed_events flag when the iterator moves to the next event and not when the missed_events flag is queried. Also clear it on reset. - Flush and stop the persistent ring buffer on panic On panic the persistent ring buffer is used to debug what caused the panic. But on some architectures, it requires flushing the memory from cache, otherwise, the ring buffer persistent memory may not have the last events and this could also cause the ring buffer to be corrupted on the next boot. - Fix nr_subbufs initialization in simple_ring_buffer_init_mm The remote simple ring buffer meta data nr_subbufs is initialized too early and gets cleared later on, making it zero and not reflect the actual number of sub-buffers. - Fix unload_page for simple_ring_buffer init rollback On error, the pages loaded need to be unloaded. To unload a page it is expected that: page = load_page(va); -> unload_page(page). But the code was doing: unload_page(va) and not unload_page(page). - Create output file from cmd_check_undefined The check for undefined symbols checks if the file *.o.checked exists and if so it skips doing the work.

ring-buffer: Flush and stop persistent ring buffer on panic
On real hardware, panic and machine reboot may not flush hardware cache
to memory. This means the persistent ring buffer, which relies on a
coherent state of memory, may not have its events written to the buffer
and they may be lost. Moreover, there may be inconsistency with the
counters which are used for validation of the integrity of the
persistent ring buffer which may cause all data to be discarded.
To avoid this issue, stop recording of the ring buffer on panic and
flush the cache of the ring buffer's memory.

tcp: fix stale per-CPU tcp_tw_isn leak enabling ISN prediction
Blamed commit moved the TIME_WAIT-derived ISN from the skb control
block to a per-CPU variable, assuming the value would always be consumed
by tcp_conn_request() for the same packet that wrote it. That assumption
is violated by multiple drop paths between the producer
(__this_cpu_write(tcp_tw_isn, isn) in tcp_v{4,6}_rcv()) and the consumer
(tcp_conn_request()):
- min_ttl / min_hopcount check
- xfrm policy check
- tcp_inbound_hash() MD5/AO mismatch
- tcp_filter() eBPF/SO_ATTACH_FILTER drop
- th->syn && th->fin discard in tcp_rcv_state_process() TCP_LISTEN
- psp_sk_rx_policy_check() in tcp_v{4,6}_do_rcv()
- tcp_checksum_complete() in tcp_v{4,6}_do_rcv()
- tcp_v{4,6}_cookie_check() returning NULL
When a packet is dropped on any of these paths, tcp_tw_isn is left set.
The next SYN processed on the same CPU then consumes the non zero value in
tcp_conn_request(), receiving a potentially predictable ISN.
This patch moves back tcp_tw_isn to skb->cb[], getting rid of the per-cpu
variable.
Note that tcp_v{4,6}_fill_cb() do not set it.
Very litle impact on overall code size/complexity:

net: shaper: rework the VALID marking (again)
Recent commit changed the semantics from NOT_VALID to VALID.
I didn't realize that the flags are not stored atomically
with the entry in XArray. There's still a race of reader
observing a VALID mark for a slot, getting interrupted,
writer replacing the entry with a different one, reader
continuing, fetching the entry which is now a different
pointer than the pointer for which VALID was meant.
The biggest consequence of this is that we may see a UAF
since net_shaper_rollback() assumed that entries without
VALID can be freed without observing RCU.
Looks like the XArray marks are buying us nothing at this
point. Let's convert the code to an explicit valid field.
The smp_load_acquire() / smp_store_release() barriers are
marginally cleaner.

net: airoha: Fix NPU RX DMA descriptor bits
In an internal review from Airoha, it was notice that the RX DMA descriptor
bits and mask are wrong. These values probably refer to an old NPU firmware
never published. The previous value works correctly but it was reported
that in some specific condition in mixed scenario with both Ethernet and
WiFi offload it's possible that RX DMA descriptor signal wrong value with
the problem to the RX ring or packets getting dropped.
To handle these specific scenario, apply the new suggested bits mask from
Airoha.
Correct functionality of both AN7581 NPU and MT7996 variant were verified
and confirmed working.

ata fixes for 7.1-rc5
- Make sure that the issuing of a deferred non-NCQ command via
workqueue feature is only used when mixing NCQ and non-NCQ commands
to the same link (i.e. return value ATA_DEFER_LINK), and nothing
else. This way we will not incorrectly try to use the feature for
e.g. PATA drivers.
- The deferred non-NCQ command was stored in a per-port struct.
When using Port Multipliers with FIS-Based Switching, we would thus
needlessly defer commands to all other links. Store the deferred QC
in a per-link struct, such that Port Multipliers with FBS will get
the same performance as before.
- The issuing of a deferred non-NCQ command via workqueue feature
broke support for Port Multipliers using Command-Based Switching.
The issuing of a deferred non-NCQ command via workqueue feature is
not compatible with the use of ap->excl_link, which PMPs with CBS
use for fairness (using implicit round robin).

Netfilter/IPVS fixes for net
The following patchset contains Netfilter/IPVS fixes for net:
1) Fix small race windows in nf_ct_helper_log() when accessing helper,
from Florian Westphal.
2) Fix potential infinite loop and race conditions in IPVS caused by
frequent user-triggered service table changes, from Julia Anastasov.
3) Fix a race condition when dumping ipsets for restore,
from Jozsef Kadlecsik.
4) Fix inner transport offset in IPv6 in nft_inner when extension
headers come before the layer 4 transport header, from Yizhou Zhao.
5) Fix incorrect iteration over IPv4 ranges in several hash set types,
from Nan Li.
6) Fix incorrect order when restoring BH in nft_inner_restore_tun_ctx(),
from Florian Westphal.
7) Validate option array from ip6t_hbh checkpath() to fix an off-by-one
access, from Zhengchuan Liang.
8) Fix race condition between ipset list -terse and concurrent updates,
from Jozsef Kadlecisk.
9) Fix race condition when inserting elements into a hash bucket, also
from Jozsef.
10) Annotate access to first free slot in hashtable, from Jozsef Kadlecsik.
11) Ensure sufficient headroom in br_netfilter neigh transmission,
from Lorenzo Bianconi.
12) Hold reference on skb->dev in nfqueue exit path, bridge local input
is speciall since skb->dev != state->indev, allowing for net_device
to go away while packet is sitting in nfqueue. From Haoze Xie.

netfilter: nf_queue: hold bridge skb->dev while queued
br_pass_frame_up() rewrites skb->dev from the ingress port to the bridge
master before queueing bridge LOCAL_IN packets. NFQUEUE only holds
references on state.in/out and bridge physdevs, so a queued bridge
packet can retain a freed bridge master in skb->dev until reinjection.
When the verdict is reinjected later, br_netif_receive_skb() re-enters
the receive path with skb->dev still pointing at the freed bridge master,
triggering a use-after-free.
Store skb->dev in the queue entry, hold a reference on it for the queue
lifetime, and use the saved device when dropping queued packets during
NETDEV_DOWN handling.

ipvs: avoid possible loop in ip_vs_dst_event on resizing
Sashiko points out that unprivileged user can frequently
call ip_vs_flush() or ip_vs_del_service() to trigger
svc_table_changes updates that can lead to infinite loop
in ip_vs_dst_event(). This can also happen if the user
triggers frequent table resizing without deleting all
services. We should also consider the possible effects
if the user triggers many NETDEV_DOWN events.
One way to solve it is to hold svc_resize_sem in
ip_vs_dst_event() but this can block the dev notifier
during the whole resizing process.
Instead, use new rw_semaphore svc_replace_sem to protect just
the svc_table replacement which is a short code section.
Then hold svc_replace_sem in ip_vs_dst_event() to serialize
with replacing the svc_table. As result, loop is avoided
as there is no need to repeat the table walking from the
start. By this way changes in svc_table_changes can happen
only when all services are removed and all dev references
dropped which allows us to abort the table walking.
As IP_VS_WORK_SVC_NORESIZE is the flag used to stop the
svc_resize_work under service_mutex, we should check only
this flag often but not while under service_mutex.
To remove the mutex_trylock() for service_mutex in the
second phase where the resizer installs the new table
after rehashing, we will avoid holding the service_mutex
there. As result, the code in configuration context which
is under service_mutex should access ipvs->svc_table under
RCU because it can be replaced at anytime and released
after a RCU grace period. As for ip_vs_zero_all(), it needs
different solution as a table walker which can escape
single RCU read-side critical section: to hold the
svc_replace_sem to prevent table to be replaced.
In ip_vs_status_show() prefer to hold svc_replace_sem
to avoid many loops, just detect if the svc_table is
removed.
Prefer the newly attached table for the u_thresh/l_thresh
checks to know when to grow/shrink while adding or deleting
services because the new table size is based on the latest
parameters.

VFIO fixes for v7.1-rc4
- Convert vfio-pci BAR resource requests and iomaps initialization
from a lazy, on-demand model to an eager pre-allocation model to
avoid races while preserving legacy error behavior. Fix unchecked
barmap access in dma-buf export path. (Matt Evans)
- Introduce an implicit unsigned cast in converting vfio-pci device
offsets to region indexes, closing a potential out-of-bounds
access through the vfio_pci_ioeventfd() interface. (Matt Evans)
- Fix a dma-buf kref underflow and stuck wait_for_completion() when
closing a previously revoked dma-buf. (Alex Williamson)

ptrace: slightly saner 'get_dumpable()' logic
The 'dumpability' of a task is fundamentally about the memory image of the task - the concept comes from whether it can core dump or not - and makes no sense when you don't have an associated mm. And almost all users do in fact use it only for the case where the task has a mm pointer. But we have one odd special case: ptrace_may_access() uses 'dumpable' to check various other things entirely independently of the MM (typically explicitly using flags like PTRACE_MODE_READ_FSCREDS). Including for threads that no longer have a VM (and maybe never did, like most kernel threads). It's not what this flag was designed for, but it is what it is. The ptrace code does check that the uid/gid matches, so you do have to be uid-0 to see kernel thread details, but this means that the traditional "drop capabilities" model doesn't make any difference for this all. Make it all make a *bit* more sense by saying that if you don't have a MM pointer, we'll use a cached "last dumpability" flag if the thread ever had a MM (it will be zero for kernel threads since it is never set), and require a proper CAP_SYS_PTRACE capability to override.

Bluetooth: serialize accept_q access
bt_sock_poll() walks the accept queue without synchronization, while
child teardown can unlink the same socket and drop its last reference.
The unsynchronized accept queue walk has existed since the initial
Bluetooth import.
Protect accept_q with a dedicated lock for queue updates and polling.
Also rework bt_accept_dequeue() to take temporary child references under
the queue lock before dropping it and locking the child socket.

macsec: use rcu_work to defer TX SA crypto cleanup out of softirq
free_txsa() is an RCU callback running in softirq context, but calls
crypto_free_aead() which can invoke vunmap() internally on hardware
crypto drivers (e.g. hisi_sec2), triggering a kernel crash.
Use rcu_work to defer the cleanup to a workqueue, for the same reasons
as the analogous fix to free_rxsa() in the previous patch.

macsec: use rcu_work to defer RX SA crypto cleanup out of softirq
crypto_free_aead() can internally invoke vunmap() (e.g. via
dma_free_attrs() in hardware crypto drivers such as hisi_sec2).
vunmap() must not be called from softirq context, but free_rxsa()
is an RCU callback that runs in softirq, leading to a kernel crash:
vunmap+0x4c/0x70
__iommu_dma_free+0xd0/0x138
dma_free_attrs+0xf4/0x100
sec_aead_exit+0x64/0xb8 [hisi_sec2]
crypto_destroy_tfm+0x98/0x110
free_rxsa+0x28/0x50 [macsec]
rcu_do_batch+0x184/0x460
rcu_core+0xf4/0x1f8
handle_softirqs+0x118/0x330
Use rcu_work to defer the cleanup to a workqueue. rcu_work dispatches
the worker asynchronously after the RCU grace period, so no thread
blocks waiting, and concurrent releases of multiple SAs naturally
share the same grace period.

mm/page_alloc: fix initialization of tags of the huge zero folio with init_on_free
__GFP_ZEROTAGS semantics are currently a bit weird, but effectively this
flag is only ever set alongside __GFP_ZERO and __GFP_SKIP_KASAN.
If we run with init_on_free, we will zero out pages during
__free_pages_prepare(), to skip zeroing on the allocation path.
However, when allocating with __GFP_ZEROTAG set, post_alloc_hook() will
consequently not only skip clearing page content, but also skip clearing
tag memory.
Not clearing tags through __GFP_ZEROTAGS is irrelevant for most pages that
will get mapped to user space through set_pte_at() later: set_pte_at() and
friends will detect that the tags have not been initialized yet
(PG_mte_tagged not set), and initialize them.
However, for the huge zero folio, which will be mapped through a PMD
marked as special, this initialization will not be performed, ending up
exposing whatever tags were still set for the pages.
The docs (Documentation/arch/arm64/memory-tagging-extension.rst) state
that allocation tags are set to 0 when a page is first mapped to user
space. That no longer holds with the huge zero folio when init_on_free is
enabled.
Fix it by decoupling __GFP_ZEROTAGS from __GFP_ZERO, passing to
tag_clear_highpages() whether we want to also clear page content.
Invert the meaning of the tag_clear_highpages() return value to have
clearer semantics.
Reproduced with the huge zero folio by modifying the check_buffer_fill
arm64/mte selftest to use a 2 MiB area, after making sure that pages have
a non-0 tag set when freeing (note that, during boot, we will not actually
initialize tags, but only set KASAN_TAG_KERNEL in the page flags).
$ ./check_buffer_fill
1..20
...
not ok 17 Check initial tags with private mapping, sync error mode and mmap memory
not ok 18 Check initial tags with private mapping, sync error mode and mmap/mprotect memory
...
This code needs more cleanups; we'll tackle that next, like
decoupling __GFP_ZEROTAGS from __GFP_SKIP_KASAN.

- Task state-machine reorg closing concurrent enable-vs-dead races: a
task exiting during the unlocked init window could trip NULL ops
derefs or skip exit_task() cleanup.
- A scx_link_sched() self-deadlock on scx_sched_lock.
- isolcpus: stop dereferencing the now-RCU-protected HK_TYPE_DOMAIN
cpumask without RCU, and stop rejecting BPF schedulers when only
cpuset isolated partitions are active.
- PREEMPT_RT: disable irq_work runs in hardirq context so dumps show the
failing task rather than the irq_work kthread.
- Assorted !CONFIG_EXT_SUB_SCHED, randconfig, and selftest build fixes.

vfio/pci: Make VFIO_PCI_OFFSET_TO_INDEX() return unsigned
VFIO_PCI_OFFSET_TO_INDEX() is used in several places with a signed
parameter (e.g. loff_t). Because it makes no sense for a BAR/resource
index to be negative, enforce this in the macro.
This fixes at least one current issue, where vfio_pci_ioeventfd() uses
this macro with an unvalidated signed loff_t returned into a signed
type, leading to a possible negative array access. This instance does
test against an out-of-bounds positive value, so treating the index as
unsigned fixes this issue.

- Appoint Steffen Eiden as a reviewer in anticipation of the KVM/s390
ability to run arm64 guests, which will inevitably lead to arm64
code being directly used on s390
- Make sure that EL2 is configured with both exception entry and exit
being Context Synchronization Events
- Handle the current vcpu being NULL on EL2 panic
- Fix the selftest_vcpu memcache being empty at the point of donation
or sharing
- Check that the memcache has enough capacity before engaging on the
share/donate path
- Fix __deactivate_fgt() to use its parameter rather than a variable
in the macro context
s390:
- Fix array overrun with large amounts of PCI devices
x86:
- Never use L0's PAUSE loop exiting while L2 is running, since it's
unlikely that a nested guest will help solving the hypervisor's
spinlock contention
- Fix emulation of MOVNTDQA
- Fix typo in Xen hypercall tracepoint
- Add back an optimization that was left behind when recently fixing
a bug
- Add module parameter to disable CET, whose implementation seems to
have issues. For now it remains enabled by default
Generic:
- Reject offset causing an unsigned overflow in kvm_reset_dirty_gfn()
Documentation:
- Update stale links

Probes fixes for v7.1-rc3
- kprobes: skip non-symbol addresses in kprobe_add_ksym_blacklist() Since the ftrace adds its NOPs at .kprobes.text section (which stores an array), a wrong entry is added when loading a module which uses "__kprobes" attribute. To solve this, add "notrace" to __kprobes functions. - test_kprobes: clear kprobes between test runs Clear all kprobes in the test program after running a test set, because Kunit test can run several times. - fprobe: Fix unregister_fprobe() to wait for RCU grace period Since the fprobe data structure is removed with hlist_del_rcu(), it should wait for the RCU grace period. If the caller waits for RCU, we can use the async variant (e.g. eBPF) -----BEGIN PGP SIGNATURE----- iQFPBAABCgA5FiEEh7BulGwFlgAOi5DV2/sHvwUrPxsFAmoCf4QbHG1hc2FtaS5o aXJhbWF0c3VAZ21haWwuY29tAAoJENv7B78FKz8bAt8H/RiNH4k/20YKE2Z56GLy N+qCb8CO8L+AroNGCAj4KRVYtBLVzxBLf+Fcdfz6UM/jQ/k2UTeh6ysIt8iWCZYA 2vJBlVDvvjWPpEZW6yCxlpEAgU2B/Xv/92ZnQjW7sGvL75+gsA1dLu1Gt6lqM5zS X335PrIN3c4g+zhwCwW8wLCpMJvyk0qnXiN3thfXTCT/P9GPZldMEAAOecyLl7C3 Y/Zc8Af3xbMdqplIoYoKRWr0uzYBb1NB2FZR7Dp6i5/5MAhVYobd23s6VXWXZwxV FHRJ6R16vCK/ftnwtOiUeuiC3iXn21XQdma6pr2nI6bRhr5v/NBXxmh5U2+tRHeF /I4= =E/h6 -----END PGP SIGNATURE----- Merge tag 'probes-fixes-v7.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull probes fixes from Masami Hiramatsu: - kprobes: skip non-symbol addresses in kprobe_add_ksym_blacklist() Since the ftrace adds its NOPs at .kprobes.text section (which stores an array), a wrong entry is added when loading a module which uses "__kprobes" attribute.

HID: core: introduce hid_safe_input_report()
hid_input_report() is used in too many places to have a commit that
doesn't cross subsystem borders. Instead of changing the API, introduce
a new one when things matters in the transport layers:
- usbhid
- i2chid
This effectively revert to the old behavior for those two transport
layers.

xen/arm: Replace __ASSEMBLY__ with __ASSEMBLER__ in interface.h
While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembly code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. This can be very confusing when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. So let's standardize now on the __ASSEMBLER__ macro that is provided by the compilers.

netfs: Fix folio->private handling in netfs_perform_write()
Under some circumstances, netfs_perform_write() doesn't correctly
manipulate folio->private between NULL, NETFS_FOLIO_COPY_TO_CACHE, pointing
to a group and pointing to a netfs_folio struct, leading to potential
multiple attachments of private data with associated folio ref leaks and
also leaks of netfs_folio structs or netfs_group refs.
Fix this by consolidating the place at which a folio is marked uptodate in
one place and having that look at what's attached to folio->private and
decide how to clean it up and then set the new group. Also, the content
shouldn't be flushed if group is NULL, even if a group is specified in the
netfs_group parameter, as that would be the case for a new folio. A
filesystem should always specify netfs_group or never specify netfs_group.
The Sashiko auto-review tool noted that it was theoretically possible that
the fpos >= ctx->zero_point section might leak if it modified a streaming
write folio. This is unlikely, but with a network filesystem, third party
changes can happen. It also pointed out that __netfs_set_group() would
leak if called multiple times on the same folio from the "whole folio
modify section".
