net: mana: Fix crash from unvalidated SHM offset read from BAR0 during FLR
During Function Level Reset recovery, the MANA driver reads
hardware BAR0 registers that may temporarily contain garbage values.
The SHM (Shared Memory) offset read from GDMA_REG_SHM_OFFSET is used
to compute gc->shm_base, which is later dereferenced via readl() in
mana_smc_poll_register(). If the hardware returns an unaligned or
out-of-range value, the driver must not blindly use it, as this would
propagate the hardware error into a kernel crash.
The following crash was observed on an arm64 Hyper-V guest running
kernel 6.17.0-3013-azure during VF reset recovery triggered by HWC
timeout.

From the crash signature x20 = ffff8000a200001b, this address
ends in 0x1b which is not 4-byte aligned, so the 'ldr w1, [x20]'
instruction (readl) triggers the arm64 alignment fault (FSC = 0x21).
The root cause is in mana_gd_init_vf_regs(), which computes:
gc->shm_base = gc->bar0_va + mana_gd_r64(gc, GDMA_REG_SHM_OFFSET);
The offset is used without any validation. The same problem exists
in mana_gd_init_pf_regs() for sriov_base_off and sriov_shm_off.
Fix this by validating all offsets before use:
- VF: check shm_off is within BAR0, properly aligned to 4 bytes
(readl requirement), and leaves room for the full 256-bit
(32-byte) SMC aperture.
- PF: check sriov_base_off is within BAR0, aligned to 8 bytes
(readq requirement), and leaves room to safely read the
sriov_shm_off register at sriov_base_off + GDMA_PF_REG_SHM_OFF.
Then check sriov_shm_off leaves room for the full SMC aperture.
All arithmetic uses subtraction rather than addition to avoid
integer overflow on garbage values.
Define SMC_APERTURE_SIZE (32 bytes, derived from the 256-bit aperture
width)
Return -EPROTO on invalid values. The existing recovery path in
mana_serv_reset() already handles -EPROTO by falling through to PCI
device rescan, giving the hardware another chance to present valid
register values after reset.

ipvs: Guard access of HK_TYPE_KTHREAD cpumask with RCU
The ip_vs_ctl.c file and the associated ip_vs.h file are the only places
in the kernel where HK_TYPE_KTHREAD cpumask is being retrieved and used.
Now that HK_TYPE_KTHREAD/HK_TYPE_DOMAIN cpumask can be changed at run
time. We need to use RCU to guard access to this cpumask to avoid a
potential UAF problem as the returned cpumask may be freed before it
is being used.
We can replace HK_TYPE_KTHREAD by HK_TYPE_DOMAIN as they are aliases
of each other, but keeping the HK_TYPE_KTHREAD name can highlight the
fact that it is the kthread initiated by ipvs that is being controlled.

ipvs: fix races around est_mutex and est_cpulist
Sashiko reports for races and possible crash around
the usage of est_cpulist_valid and sysctl_est_cpulist.
The problem is that we do not lock est_mutex in some
places which can lead to wrong write ordering and
as result problems when calling cpumask_weight()
and cpumask_empty().
Fix them by moving the est_max_threads read/write under
locked est_mutex. Do the same for one ip_vs_est_reload_start()
call to protect the cpumask_empty() usage of sysctl_est_cpulist.
To remove the chance of deadlock while stopping the
estimation kthreads, keep the data structure for kthread 0
even after last estimator is removed and do not hold mutexes
while stopping this task. Now we will use a new flag 'needed'
to know when kthread 0 should run. The kthreads above 0
do not use mutexes, so stop them under est_mutex because
their kthread data still can be destroyed if they do not
serve estimators. Now all kthreads will be started by
the est_reload_work to properly serialize the stop/start
for kthread 0.
Reduce the use of service_mutex in ip_vs_est_calc_phase()
because under est_mutex we can safely walk est_kt_arr to
stop the kthreads above slot 0.
As ip_vs_stop_estimator() for tot_stats should be called
under service_mutex, do it early in the netns exit path
in ip_vs_flush() to avoid locking the mutex again later.
It still should be called in ip_vs_control_net_cleanup_sysctl()
when we are called during netns init error. Use -2 for ktid
as indicator if estimator was already stopped.
Finally, fix use-after-free for kd->est_row in
ip_vs_est_calc_phase(). est->ktrow should simply switch to
a delay value while estimator is linked to est_temp_list.

Netfilter fixes for net
The following batch contains Netfilter fixes for net:
1) Replace skb_try_make_writable() by skb_ensure_writable() in
nft_fwd_netdev and the flowtable to deal with uncloned packets
having their network header in paged fragments.
2) Drop packet if output device does not exist and ensure sufficient
headroom in nft_fwd_netdev before transmitting the skb.
3) Use the existing dup recursion counter in nft_fwd_netdev for the
neigh_xmit variant, from Weiming Shi.
4) Add .check_hooks interface to x_tables to detach the control plane
hook check based on the match/target configuration. Then, update
nft_compat to use .check_hooks from .validate path, this fixes a
lack of hook validation for several match/targets.
5) Fix incorrect .usersize in xt_CT, from Florian Westphal.
6) Fix a memleak with netdev tables in dormant state,
from Florian Westphal.
7) Several patches to check if the packet is a fragment, then skip
layer 4 inspection, for x_tables and nf_tables; as well as common
nf_socket infrastructure. The xt_hashlimit match drops fragments
to stay consistent with the existing approach when failing to parse
the layer 4 protocol header.
8) Ensure sufficient headroom in the flowtable before transmitting
the skb.
9) Fix the flowtable inline vlan approach for double-tagged vlan:
Reverse the iteration over .encap[] since it represents the
encapsulation as seen from the ingress path. Postpone pushing
layer 2 header so output device is available to calculate needed
headroom. Finally, add and use nf_flow_vlan_push() to fix it.
10) Fix flowtable inline pppoe with GSO packets. Moreover, use
FLOW_OFFLOAD_XMIT_DIRECT to fill up destination hardware
address since neighbour cache does not exist in pppoe.
11) Use skb_pull_rcsum() to decapsulate vlan and pppoe headers, for
double-tagged vlan in particular this should provide some benefits
in certain scenarios.
More notes regarding 9-11):
- sashiko is also signalling to use it for IPIP headers, but that needs
more adjustments such setting skb->protocol after removing the IPIP
header, will follow up in a separated patch.
- I plan to submit selftests to cover double-tagged-vlan. As for pppoe,
it should be possible but that would mandate a few userspace dependencies.
This has been semi-automatically tested by me and reporters describing
broken double-vlan-tagged and pppoe currently in the flowtable.

ipv6: Implement limits on extension header parsing
ipv6_{skip_exthdr,find_hdr}() and ip6_{tnl_parse_tlv_enc_lim,
protocol_deliver_rcu}() iterate over IPv6 extension headers until they
find a non-extension-header protocol or run out of packet data. The
loops have no iteration counter, relying solely on the packet length
to bound them. For a crafted packet with 8-byte extension headers
filling a 64KB jumbogram, this means a worst case of up to ~8k
iterations with a skb_header_pointer call each. ipv6_skip_exthdr(),
for example, is used where it parses the inner quoted packet inside
an incoming ICMPv6 error:
- icmpv6_rcv
- checksum validation
- case ICMPV6_DEST_UNREACH
- icmpv6_notify
- pskb_may_pull() <- pull inner IPv6 header
- ipv6_skip_exthdr() <- iterates here
- pskb_may_pull()
- ipprot->err_handler() <- sk lookup
The per-iteration cost of ipv6_skip_exthdr itself is generally
light, but skb_header_pointer becomes more costly on reassembled
packets: the first ~1232 bytes of the inner packet are in the skb's
linear area, but the remaining ~63KB are in the frag_list where
skb_copy_bits is needed to read data.
Initially, the idea was to add a configurable limit via a new
sysctl knob with default 8, in line with knobs from commit

netfilter: flowtable: fix inline pppoe encapsulation in xmit path
Address two issues in the inline pppoe encapsulation:
- Add needs_gso_segment flag to segment PPPoE packets in software
given that there is no GSO support for this.
- Use FLOW_OFFLOAD_XMIT_DIRECT since neighbour cache is not available
in point-to-point device, use the hardware address that is obtained
via flowtable path discovery (ie. fill_forward_path).

tracing fixes for v7.1:
- Fix inverted check of registering the stats for branch tracing When calling register_stat_tracer() which returns zero on success and negative on error, the callers were checking the return of zero as an error and printing a warning message. Because this was just a normal printk() message and not a WARN(), it wasn't caught in any testing. Fix the check to print the warning message when an error actually happens. - Fix a typo in a comment in tracepoint.h - Limit the size of event probes to 3K in size It is possible to create a dynamic event probe via the tracefs system that is greater than the max size of an event that the ring buffer can hold. This basically causes the event to become useless. Limit the size of an event probe to be 3K as that should be large enough to handle any dynamic events being created, and fits within the PAGE_SIZE sub-buffers of the ring buffer. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCafJn9hQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6quUaAP9ezC2VXWugRIhOEmK0pIpY90zddsyv xYTa3XuPP2r5JQEA8DcmH6fTo7JJxzbbyWPot/EgaqMt5XguqKC7txhjfww= =+e7q -----END PGP SIGNATURE----- Merge tag 'trace-v7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix inverted check of registering the stats for branch tracing When calling register_stat_tracer() which returns zero on success and negative on error, the callers were checking the return of zero as an error and printing a warning message.

netfilter: nft_fwd_netdev: use recursion counter in neigh egress path
nft_fwd_neigh can be used in egress chains (NF_NETDEV_EGRESS). When the
forwarding rule targets the same device or two devices forward to each
other, neigh_xmit() triggers dev_queue_xmit() which re-enters
nf_hook_egress(), causing infinite recursion and stack overflow.
Move the nf_get_nf_dup_skb_recursion() accessor and NF_RECURSION_LIMIT
to the shared header nf_dup_netdev.h as a static inline, so that
nft_fwd_netdev can use the recursion counter directly without exported
function call overhead. Guard neigh_xmit() with the same recursion
limit already used in nf_do_netdev_egress().
[ Updated to cache the nf_get_nf_dup_skb_recursion pointer. --pablo ]

Apparently, arp_tables was never updated to deal with IEEE1394 ARP properly. To deal with this, return no match in case the target hardware address selector is used, either for inverse or normal match. Moreover, arpt_mangle disallows mangling of the target hardware and IP address because, it is not worth to adjust the offset calculation to fix this, we suspect no users of arp_tables for this family. 2) Use list_del_rcu() to delete device hooks in nf_tables, this hook list is RCU protected, concurrent netlink dump readers can be walking on this list, fix it by adding a helper function and use it for consistency. From Florian Westphal. 3) Add list_splice_rcu(), this is useful for joining the local list of new device hooks to the RCU protected hook list in chain and flowtable. Reviewed by Paul E. McKenney. 4) Use list_splice_rcu() to publish the new device hooks in chain and flowtable to fix concurrent netlink dump traversal. 5) Add a new hook transaction object to track device hook deletions. The current approach moves device hooks to be deleted around during the preparation phase, this breaks concurrent RCU reader via netlink dump. This new hook transaction is combined with NFT_HOOK_REMOVE flag to annotate hooks for removal in the preparation phase. 6) xt_policy inbound policy check in strict mode can lead to out-of-bound access of the secpath array due to incorrect. The iteration over the secpath needs to be reversed in the inbound to check for the human readable policy, expecting inner in first position and outer in second position, the secpath from inbound actually stores outer in first position then in second position. From Jiexun Wang. 7) Fix possible zero shift in nft_bitwise triggering UBSAN splat, reject zero shift from control plane, from Kai Ma. 8) Replace simple_strtoul() in the conntrack SIP helper since it relies on nul-terminated strings.

sched_ext: Fixes for v7.1-rc1
The merge window pulled in the cgroup sub-scheduler infrastructure, and
new AI reviews are accelerating bug reporting and fixing - hence the
larger than usual fixes batch.
- Use-after-frees during scheduler load/unload. The disable path
could free the BPF scheduler while deferred irq_work / kthread work
was still in flight; cgroup setter callbacks read the active
scheduler outside the rwsem that synchronizes against teardown.
Fixed both, and reused the disable drain in the enable error paths
so the BPF JIT page can't be freed under live callbacks.
- Several BPF op invocations didn't tell the framework which runqueue
was already locked, so helper kfuncs that re-acquire the runqueue
by CPU could deadlock on the held lock. Fixed at the affected
callsites, including recursive parent-into-child dispatch.
- The hardlockup notifier ran from NMI but eventually took a
non-NMI-safe lock. Bounced through irq_work.
- A handful of bugs in the new sub-scheduler hierarchy: helper
kfuncs hard-coded the root instead of resolving the caller's
scheduler; the enable error path tried to disable per-task state
that had never been initialized, and leaked cpus_read_lock on the
way out; a sysfs object was leaked on every load/unload; the
dispatch fast-path used the root scheduler instead of the task's;
and a couple of CONFIG #ifdef guards were misclassified.
- Verifier-time hardening: BPF programs of unrelated struct_ops
types (e.g. tcp_congestion_ops) could call sched_ext kfuncs - a
semantic bug and, once sub-sched was enabled, a KASAN
out-of-bounds read. Now rejected at load. Plus a few NULL and
cross-task argument checks on sched_ext kfuncs, and a selftest
covering the new deny.
- rhashtable (Herbert): restored the insecure_elasticity toggle and
bounced the deferred-resize kick through irq_work to break a
lock-order cycle observable from raw-spinlock callers. sched_ext's
scheduler-instance hash is the first user of both.
- The bypass-mode load balancer used file-scope cpumasks; with
multiple scheduler instances now possible, those raced. Moved
per-instance, plus a follow-up to skip tasks whose recorded CPU is
stale relative to the new owning runqueue.
- Smaller fixes: a dispatch queue's first-task tracking misbehaved
when a parked iterator cursor sat in the list; the runqueue's
next-class wasn't promoted on local-queue enqueue, leaving an SCX
task behind RT in edge cases; the reference qmap scheduler stopped
erroring on legitimate cross-scheduler task-storage misses.

ipmr: Free mr_table after RCU grace period.
With CONFIG_IP_MROUTE_MULTIPLE_TABLES=n, ipmr_fib_lookup()
does not check if net->ipv4.mrt is NULL.
Since default_device_exit_batch() is called after ->exit_rtnl(),
a device could receive IGMP packets and access net->ipv4.mrt
during/after ipmr_rules_exit_rtnl().
If ipmr_rules_exit_rtnl() had already cleared it and freed the
memory, the access would trigger null-ptr-deref or use-after-free.
Let's fix it by using RCU helper and free mrt after RCU grace
period.
In addition, check_net(net) is added to mroute_clean_tables()
and ipmr_cache_unresolved() to synchronise via mfc_unres_lock.
This prevents ipmr_cache_unresolved() from putting skb into
c->_c.mfc_un.unres.unresolved after mroute_clean_tables()
purges it.
For the same reason, timer_shutdown_sync() is moved after
mroute_clean_tables().
Since rhltable_destroy() holds mutex internally, rcu_work is
used, and it is placed as the first member because rcu_head
must be placed within <4K offset. mr_table is alraedy 3864
bytes without rcu_work.
Note that IP6MR is not yet converted to ->exit_rtnl(), so this
change is not needed for now but will be.
Fixes:

Delete some obsolete networking code
Old code like amateur radio and NFC have long been a burden to core networking developers. syzbot loves to find bugs in BKL-era code, and noobs try to fix them. If we want to have a fighting chance of surviving the LLM-pocalypse this code needs to find a dedicated owner or get deleted. We've talked about these deletions multiple times in the past and every time someone wanted the code to stay. It is never very clear to me how many of those people actually use the code vs are just nostalgic to see it go. Amateur radio did have occasional users (or so I think) but most users switched to user space implementations since its all super slow stuff. Nobody stepped up to maintain the kernel code. We were lucky enough to find someone who wants to help with NFC so we're giving that a chance. Let's try to put the rest of this code behind us.

Including fixes from Netfilter.
Steady stream of fixes. Last two weeks feel comparable to the two
weeks before the merge window. Lots of AI-aided bug discovery.
A newer big source is Sashiko/Gemini (Roman Gushchin's system),
which points out issues in existing code during patch review
(maybe 25% of fixes here likely originating from Sashiko).
Nice thing is these are often fixed by the respective maintainers,
not drive-bys.
Current release - new code bugs:
- kconfig: MDIO_PIC64HPSC should depend on ARCH_MICROCHIP
Previous releases - regressions:
- add async ndo_set_rx_mode and switch drivers which we promised
to be called under the per-netdev mutex to it
- dsa: remove duplicate netdev_lock_ops() for conduit ethtool ops
- hv_sock: report EOF instead of -EIO for FIN
- vsock/virtio: fix MSG_PEEK calculation on bytes to copy
Previous releases - always broken:
- ipv6: fix possible UAF in icmpv6_rcv()
- icmp: validate reply type before using icmp_pointers
- af_unix: drop all SCM attributes for SOCKMAP
- netfilter: fix a number of bugs in the osf (OS fingerprinting)
- eth: intel: fix timestamp interrupt configuration for E825C
Misc:
- bunch of data-race annotations

eventpoll: refresh eventpoll_release() fast-path comment
The old comment justified the lockless READ_ONCE(file->f_ep) check with "False positives simply cannot happen because the file is on the way to be removed and nobody ( but eventpoll ) has still a reference to this file." That reasoning was the root of the UAF fixed in "eventpoll: fix ep_remove struct eventpoll / struct file UAF": __ep_remove() could clear f_ep while another close raced past the fast path and freed the watched eventpoll / recycled the struct file slot. With ep_remove() now pinning @file via epi_fget() across the f_ep clear and hlist_del_rcu(), the invariant is re-established for the right reason: anyone who might clear f_ep holds @file alive for the duration, so a NULL observation really does mean no concurrent eventpoll path has work left on this file. Refresh the comment accordingly so the next reader doesn't inherit the broken model.

rxrpc: Fix re-decryption of RESPONSE packets
If a RESPONSE packet gets a temporary failure during processing, it may end
up in a partially decrypted state - and then get requeued for a retry.
Fix this by just discarding the packet; we will send another CHALLENGE
packet and thereby elicit a further response. Similarly, discard an
incoming CHALLENGE packet if we get an error whilst generating a RESPONSE;
the server will send another CHALLENGE.

rxrpc: Fix potential UAF after skb_unshare() failure
If skb_unshare() fails to unshare a packet due to allocation failure in
rxrpc_input_packet(), the skb pointer in the parent (rxrpc_io_thread())
will be NULL'd out. This will likely cause the call to
trace_rxrpc_rx_done() to oops.
Fix this by moving the unsharing down to where rxrpc_input_call_event()
calls rxrpc_input_call_packet(). There are a number of places prior to
that where we ignore DATA packets for a variety of reasons (such as the
call already being complete) for which an unshare is then avoided.
And with that, rxrpc_input_packet() doesn't need to take a pointer to the
pointer to the packet, so change that to just a pointer.

rxrpc: Fix rxkad crypto unalignment handling
Fix handling of a packet with a misaligned crypto length. Also handle
non-ENOMEM errors from decryption by aborting. Further, remove the
WARN_ON_ONCE() so that it can't be remotely triggered (a trace line can
still be emitted).
Fixes:

ACPI support fixes for 7.1-rc1
- Add an acpi_get_cpu_uid() stub helper to address an x86 Xen support
build breakage (Arnd Bergmann)
- Use acpi_dev_put() in object add error paths in the ACPI core to
avoid refcount leaks (Guangshuo Li)
- Adjust the file entry in the recently added NVIDIA GHES HANDLER entry
in MAINTAINERS to the actual existing file (Lukas Bulwahn)
- Add backlight=native quirk for Dell OptiPlex 7770 AIO to the ACPI

net: remove unused ATM protocols and legacy ATM device drivers
Remove the ATM protocol modules and PCI/SBUS ATM device drivers that are no longer in active use. The ATM core protocol stack, PPPoATM, BR2684, and USB DSL modem drivers (drivers/usb/atm/) are retained in-tree to maintain PPP over ATM (PPPoA) and PPPoE-over-BR2684 support for DSL connections. The Solos ADSL2+ PCI driver is also retained. Removed ATM protocol modules: - net/atm/clip.c - Classical IP over ATM (RFC 2225) - net/atm/lec.c - LAN Emulation Client (LANE) - net/atm/mpc.c, mpoa_caches.c, mpoa_proc.c - Multi-Protocol Over ATM Removed PCI/SBUS ATM device drivers (drivers/atm/): - adummy, atmtcp - software/testing ATM devices - eni - Efficient Networks ENI155P (OC-3, ~1995) - fore200e - FORE Systems 200E PCI/SBUS (OC-3, ~1999) - he - ForeRunner HE (OC-3/OC-12, ~2000) - idt77105 - IDT 77105 25 Mbps ATM PHY - idt77252 - IDT 77252 NICStAR II (OC-3, ~2000) - iphase - Interphase ATM PCI (OC-3/DS3/E3) - lanai - Efficient Networks Speedstream 3010 - nicstar - IDT 77201 NICStAR (155/25 Mbps, ~1999) - suni - PMC S/UNI SONET PHY library Also clean up references in: - net/bridge/ - remove ATM LANE hook (br_fdb_test_addr_hook, br_fdb_test_addr) - net/core/dev.c - remove br_fdb_test_addr_hook export - defconfig files - remove ATM driver config options The removed code is moved to an out-of-tree module package (mod-orphan).

net: remove ax25 and amateur radio (hamradio) subsystem
Remove the amateur radio (AX.25, NET/ROM, ROSE) protocol implementation and all associated hamradio device drivers from the kernel tree. This set of protocols has long been a huge bug/syzbot magnet, and since nobody stepped up to help us deal with the influx of the AI-generated bug reports we need to move it out of tree to protect our sanity. The code is moved to an out-of-tree repo: https://github.com/linux-netdev/mod-orphan if it's cleaned up and reworked there we can accept it back. Minimal stub headers are kept for include/net/ax25.h (AX25_P_IP, AX25_ADDR_LEN, ax25_address) and include/net/rose.h (ROSE_ADDR_LEN) so that the conditional integration code in arp.c and tun.c continues to compile and work when the out-of-tree modules are loaded.

net: remove ISDN subsystem and Bluetooth CMTP
Remove the ISDN (mISDN, CAPI) subsystem and Bluetooth CMTP protocol from the kernel tree. ISDN is a pretty old technology and it's unclear whether anyone still uses it. I went over the last few years of git history and all the commits are either tree-wide conversions or syzbot/static analyzer fixes. When we discussed removal in the past IIRC there were some concerns about ISDN still being used in parts of Germany. Unfortunately, the code base is quite old, none of the current maintainers are familiar with it and AI tools will have a field day finding bugs here. Delete this code and preserve it in an out-of-tree repository for any remaining users: https://github.com/linux-netdev/mod-orphan UAPI constants AF_ISDN/PF_ISDN and the SELinux isdn_socket class are preserved for ABI stability, but the rest of uAPI is removed.

8021q: use RCU for egress QoS mappings
The TX fast path and reporting paths walk egress QoS mappings without RTNL. Convert the mapping lists to RCU-protected pointers, use RCU reader annotations in readers, and defer freeing mapping nodes with an embedded rcu_head. This prepares the egress QoS mapping code for safe removal of mapping nodes in a follow-up change while preserving the current behavior.
