net/rds: Fix UBSAN: array-index-out-of-bounds in rds_cmsg_recv
Syzcaller UBSAN crash occurs in rds_cmsg_recv(),
which reads inc->i_rx_lat_trace[j + 1] with index 4 (3 + 1),
but with array size of 4 (RDS_RX_MAX_TRACES).
Here 'j' is assigned from rs->rs_rx_trace[i] and in-turn from
trace.rx_trace_pos[i] in rds_recv_track_latency(),
with both arrays sized 3 (RDS_MSG_RX_DGRAM_TRACE_MAX). So fix the
off-by-one bounds check in rds_recv_track_latency() to prevent
a potential crash in rds_cmsg_recv().

net: micrel: Fix PTP frame parsing for lan8814
The HW has the capability to check each frame if it is a PTP frame,
which domain it is, which ptp frame type it is, different ip address in
the frame. And if one of these checks fail then the frame is not
timestamp. Most of these checks were disabled except checking the field
minorVersionPTP inside the PTP header. Meaning that once a partner sends
a frame compliant to 8021AS which has minorVersionPTP set to 1, then the
frame was not timestamp because the HW expected by default a value of 0
in minorVersionPTP. This is exactly the same issue as on lan8841.
Fix this issue by removing this check so the userspace can decide on this.

dpll: fix register pin with unregistered parent pin
In case of multiple kernel module instances using the same dpll device: if only one registers dpll device, then only that one can register directly connected pins with a dpll device. When unregistered parent is responsible for determining if the muxed pin can be registered with it or not, the drivers need to be loaded in serialized order to work correctly - first the driver instance which registers the direct pins needs to be loaded, then the other instances could register muxed type pins. Allow registration of a pin with a parent even if the parent was not yet registered, thus allow ability for unserialized driver instance load order. Do not WARN_ON notification for unregistered pin, which can be invoked for described case, instead just return error. Fixes: |

dpll: fix userspace availability of pins
If parent pin was unregistered but child pin was not, the userspace
would see the "zombie" pins - the ones that were registered with
a parent pin (dpll_pin_on_pin_register(..)).
Technically those are not available - as there is no dpll device in the
system. Do not dump those pins and prevent userspace from any
interaction with them. Provide a unified function to determine if the
pin is available and use it before acting/responding for user requests.

dpll: fix pin dump crash for rebound module
When a kernel module is unbound but the pin resources were not entirely freed (other kernel module instance of the same PCI device have had kept the reference to that pin), and kernel module is again bound, the pin properties would not be updated (the properties are only assigned when memory for the pin is allocated), prop pointer still points to the kernel module memory of the kernel module which was deallocated on the unbind. If the pin dump is invoked in this state, the result is a kernel crash. Prevent the crash by storing persistent pin properties in dpll subsystem, copy the content from the kernel module when pin is allocated, instead of using memory of the kernel module. Fixes: |

tun: add missing rx stats accounting in tun_xdp_act
The TUN can be used as vhost-net backend, and it is necessary to
count the packets transmitted from TUN to vhost-net/virtio-net.
However, there are some places in the receive path that were not
taken into account when using XDP. It would be beneficial to also
include new accounting for successfully received bytes using
dev_sw_netstats_rx_add.

net: fix removing a namespace with conflicting altnames
Mark reports a BUG() when a net namespace is removed.
kernel BUG at net/core/dev.c:11520!
Physical interfaces moved outside of init_net get "refunded"
to init_net when that namespace disappears. The main interface
name may get overwritten in the process if it would have
conflicted. We need to also discard all conflicting altnames.
Recent fixes addressed ensuring that altnames get moved
with the main interface, which surfaced this problem.

idpf: distinguish vports by the dev_port attribute
idpf registers multiple netdevs (virtual ports) for one PCI function,
but it does not provide a way for userspace to distinguish them with
sysfs attributes. Per Documentation/ABI/testing/sysfs-class-net, it is
a bug not to set dev_port for independent ports on the same PCI bus,
device and function.
Without dev_port set, systemd-udevd's default naming policy attempts
to assign the same name ("ens2f0") to all four idpf netdevs on my test
system and obviously fails, leaving three of them with the initial
eth<N> name.
With this patch, systemd-udevd is able to assign unique names to the
netdevs (e.g. "ens2f0", "ens2f0d1", "ens2f0d2", "ens2f0d3").
The Intel-provided out-of-tree idpf driver already sets dev_port. In
this patch I chose to do it in the same place in the idpf_cfg_netdev
function.

udp: fix busy polling
Generic sk_busy_loop_end() only looks at sk->sk_receive_queue
for presence of packets.
Problem is that for UDP sockets after blamed commit, some packets
could be present in another queue: udp_sk(sk)->reader_queue
In some cases, a busy poller could spin until timeout expiration,
even if some packets are available in udp_sk(sk)->reader_queue.
v3: - make sk_busy_loop_end() nicer (Willem)
v2: - add a READ_ONCE(sk->sk_family) in sk_is_inet() to avoid KCSAN splats.
- add a sk_is_inet() check in sk_is_udp() (Willem feedback)
- add a sk_is_inet() check in sk_is_tcp().

llc: Drop support for ETH_P_TR_802_2.
syzbot reported an uninit-value bug below. [0]
llc supports ETH_P_802_2 (0x0004) and used to support ETH_P_TR_802_2
(0x0011), and syzbot abused the latter to trigger the bug.
write$tun(r0, &(0x7f0000000040)={@val={0x0, 0x11}, @val, @mpls={[], @llc={@snap={0xaa, 0x1, ')', "90e5dd"}}}}, 0x16)
llc_conn_handler() initialises local variables {saddr,daddr}.mac
based on skb in llc_pdu_decode_sa()/llc_pdu_decode_da() and passes
them to __llc_lookup().
However, the initialisation is done only when skb->protocol is
htons(ETH_P_802_2), otherwise, __llc_lookup_established() and
__llc_lookup_listener() will read garbage.
The missing initialisation existed prior to commit

llc: make llc_ui_sendmsg() more robust against bonding changes
syzbot was able to trick llc_ui_sendmsg(), allocating an skb with no
headroom, but subsequently trying to push 14 bytes of Ethernet header [1]
Like some others, llc_ui_sendmsg() releases the socket lock before
calling sock_alloc_send_skb().
Then it acquires it again, but does not redo all the sanity checks
that were performed.
This fix:
- Uses LL_RESERVED_SPACE() to reserve space.
- Check all conditions again after socket lock is held again.
- Do not account Ethernet header for mtu limitation.

vlan: skip nested type that is not IFLA_VLAN_QOS_MAPPING
In the vlan_changelink function, a loop is used to parse the nested
attributes IFLA_VLAN_EGRESS_QOS and IFLA_VLAN_INGRESS_QOS in order to
obtain the struct ifla_vlan_qos_mapping. These two nested attributes are
checked in the vlan_validate_qos_map function, which calls
nla_validate_nested_deprecated with the vlan_map_policy.
However, this deprecated validator applies a LIBERAL strictness, allowing
the presence of an attribute with the type IFLA_VLAN_QOS_UNSPEC.
Consequently, the loop in vlan_changelink may parse an attribute of type
IFLA_VLAN_QOS_UNSPEC and believe it carries a payload of
struct ifla_vlan_qos_mapping, which is not necessarily true.
To address this issue and ensure compatibility, this patch introduces two
type checks that skip attributes whose type is not IFLA_VLAN_QOS_MAPPING.

bnxt_en: Fix possible crash after creating sw mqprio TCs
The driver relies on netdev_get_num_tc() to get the number of HW
offloaded mqprio TCs to allocate and free TX rings. This won't
work and can potentially crash the system if software mqprio or
taprio TCs have been setup. netdev_get_num_tc() will return the
number of software TCs and it may cause the driver to allocate or
free more TX rings that it should. Fix it by adding a bp->num_tc
field to store the number of HW offload mqprio TCs for the device.
Use bp->num_tc instead of netdev_get_num_tc().
This fixes a crash like this:

bnxt_en: Prevent kernel warning when running offline self test
We call bnxt_half_open_nic() to setup the chip partially to run
loopback tests. The rings and buffers are initialized normally
so that we can transmit and receive packets in loopback mode.
That means page pool buffers are allocated for the aggregation ring
just like the normal case. NAPI is not needed because we are just
polling for the loopback packets.
When we're done with the loopback tests, we call bnxt_half_close_nic()
to clean up. When freeing the page pools, we hit a WARN_ON()
in page_pool_unlink_napi() because the NAPI state linked to the
page pool is uninitialized.
The simplest way to avoid this warning is just to initialize the
NAPIs during half open and delete the NAPIs during half close.
Trying to skip the page pool initialization or skip linking of
NAPI during half open will be more complicated.
This fix avoids this warning:

bnxt_en: Fix RSS table entries calculation for P5_PLUS chips
The existing formula used in the driver to calculate the number of RSS
table entries is to round up the number of RX rings to the next integer
multiples of 64 (e.g. 64, 128, 192, ..). This is incorrect. The valid
values supported by the chip are 64, 128, 256, 512 only (power of 2
starting from 64). When the number of RX rings is greater than 128, the
entry size will likely be wrong. Firmware will round down the invalid
value (e.g. 192 rounded down to 128) provided by the driver, causing some
RSS rings to not receive any packets.
We already have an existing function bnxt_calc_nr_ring_pages() to
do this calculation. Use it in bnxt_get_nr_rss_ctxs() to calculate the
number of RSS contexts correctly for P5_PLUS chips.

bnxt_en: Wait for FLR to complete during probe
The first message to firmware may fail if the device is undergoing FLR.
The driver has some recovery logic for this failure scenario but we must

When the socket receives the ACK packet during the three-way handshake,
it will hold spinlock. And then the user actively shutdowns the socket
and listens to the socket immediately, the spinlock will be initialized.
When the socket is going to release the spinlock, a warning is generated.
Also the same issue to fastopenq.lock.
Move init spinlock to inet_create and inet_accept to make sure init the

the test timeout to allow the test to complete.
I ran the test in slightly different VMs (including one without HW
virtualization support) and got runtimes of 13m39.760s, 13m31.238s, and
13m2.956s. Use a ~1.5x "safety factor" and set the timeout to 1200s.

when we dump it. Assumed that the connection has been registered in a
link group by smc_conn_create() but the rmb_desc has not yet been
initialized by smc_buf_create(), thus causing the illegal access to
conn->rmb_desc. So fix it by checking before dump.

This cycle, I2C removes the currently unused CLASS_DDC support
(controllers set the flag, but there is no client to use it). Also, CLASS_SPD support gets simplified to prepare removal in the future. Class based instantiation is not recommended these days anyhow. Furthermore, I2C core now creates a debugfs directory per I2C adapter. Current bus driver users were converted to use it. Then, there are also quite some driver updates. Standing out are patches for the wmt-driver which is refactored to support more variants. This is the rebased pull request where a large series for the designware driver was dropped. -----BEGIN PGP SIGNATURE----- iQJDBAABCgAtFiEEOZGx6rniZ1Gk92RdFA3kzBSgKbYFAmWph0UPHHdzYUBrZXJu ZWwub3JnAAoJEBQN5MwUoCm2kbIQAJotSmX0mM+nNPReYCMMiloxoxUwgpiErNwY WDrYQSezthAJ1LDsGOEeLcE4f4I+UcUHBO1BoERtOZg3cGtE0Ii5N845sp100S9O ktyaKS5utoErymThWFFrnZX60/8yKXUMzZmNzy96560gPcxbFyyyVhKfBSPzK9T+ O8CGu7GRNqgWHlvH3yqGeCbreWYrYVSrluEpBu6807cp3zDxrU+autOnsewm5+md ka3DdqrbxJSblYK8fJKESAUgkRmZgYKbgl0iiCuqX+ib6I4OA3Z68ny7dl0fY3Ws vwt7d88SaBKDdJmUZyb/sm4aJsW69GN+ECZolxrn4TIw45k4tes2s6Ma5+TV3E9h Fd1RuqduFEqQ7cj31UPe2x8rgj5Fo5nbjCWxdZv+/3zF8+cHwi8iwkp2PScsPCsa fmCdehUE5DrgobsRNANe6XJzxY5wp2VNpGEWKeaQz2Z0/d9T1YFS7a8aewvhXoPC isZboi6GQh2XoE8UgGJa29VUuaIkUW513DwCGw8mz1yKN+kHGcsRXXjkjaZoQn3U MMvh/zkI2Hpy/m2R8PWeIq5XhLJvmlZ19JJzUHJIjXh9Fn9EVtXhlUleh6mzMfeM n8NOg7Eukep2sBgmaufkUKz2Jtogs59YDSXZEvqJjIkPM2Wi0hA18Qj+pilES1ff 3ckk3mxY =8D3Q -----END PGP SIGNATURE----- Merge tag 'i2c-for-6.8-rc1-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c updates from Wolfram Sang: "This removes the currently unused CLASS_DDC support (controllers set the flag, but there is no client to use it).

Merge tag 'gpio-fixes-for-v6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio fixes from Bartosz Golaszewski:
"Apart from some regular driver fixes there's a relatively big revert
of the locking changes that were introduced to GPIOLIB in this merge
window.
This is because it turned out that some legacy GPIO interfaces - that
need to translate a number from the global GPIO numberspace to the
address of the relevant descriptor, thus running a GPIO device lookup
and taking the GPIO device list lock - are still used in old code from
atomic context resulting in "scheduling while atomic" errors.
I'll try to make the read-only part of the list access entirely
lockless using SRCU but this will take some time so let's go back to
the old global spinlock for now.
Summary:
- revert the changes aiming to use a read-write semaphore to protect
the list of GPIO devices due to calls to legacy API taking that
lock from atomic context in old code
- fix inverted logic in DEFINE_FREE() for GPIO device references
- check the return value of bgpio_init() in gpio-mlxbf3
- fix node address in the DT bindings example for gpio-xilinx
- fix signedness bug in gpio-rtd
- fix kernel-doc warnings in gpio-en7523"

pwm changes for 6.8, take 2
The first commit fixes a duplicate cleanup in an error path introduced in pwm/for-6.8-rc1~13. The second cares for an out-of-bounds access. In practise it doesn't happen---otherwise someone would have noticed since v5.17-rc1 I guess---because the device tree binding for the two drivers using of_pwm_single_xlate() only have args->args_count == 1. A device-tree that doesn't conform to the respective bindings could trigger that easily however. The third and last one corrects the request callback of the jz4740 pwm driver which used dev_err_probe() long after .probe() completed. This is conceptually wrong because dev_err_probe() might call device_set_deferred_probe_reason() which is nonsensical after the driver is bound. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEP4GsaTp6HlmJrf7Tj4D7WH0S/k4FAmWo3dwACgkQj4D7WH0S /k5L3Qf8Db1uwUEGFXjjMIS82djW6u8rAEu1bEVf0yqhFKB3zo/PO4b1bfTHvKGo SwSflvZ2UB+bcby1yIZTP1yUbDH1O3WFfxgYwdUR715us/iMCV5sYvuNagi0Fp8O edR1Ntr/CmaU5VeDyml7ZUIHj7oZ50hd1dvvEugvKQKEVvW8yHBR2OEuqI38cIyK ItsQPrN9ld7PXzE0UFWMJpi3lbo+Q4KEYbx0yzBmBGogLXi+nRCIGtMB5KzdUSvf K4mQPHDmUyHsviXyjXcywst7sL1ebUcI3FicvCf4by/Sek5jZQGtLoyRS0m4FkRw V/TQMiLhU5iKr84wPQUvw6ZYmcXxog== =BP0a -----END PGP SIGNATURE----- Merge tag 'pwm/for-6.8-2' of gitolite.kernel.org:pub/scm/linux/kernel/git/ukleinek/linux Pull pwm fixes from Uwe Kleine-König: - fix a duplicate cleanup in an error path introduced in this merge window - fix an out-of-bounds access In practise it doesn't happen - otherwise someone would have noticed since v5.17-rc1 I guess - because the device tree binding for the two drivers using of_pwm_single_xlate() only have args->args_count == 1.

iommufd for 6.8
This brings the first of three planned user IO page table invalidation
operations:
- IOMMU_HWPT_INVALIDATE allows invalidating the IOTLB integrated into the
iommu itself. The Intel implementation will also generate an ATC
invalidation to flush the device IOTLB as it unambiguously knows the
device, but other HW will not.
It goes along with the prior PR to implement userspace IO page tables (aka
nested translation for VMs) to allow Intel to have full functionality for
simple cases. An Intel implementation of the operation is provided.
Fix a small bug in the selftest mock iommu driver probe.

More eventfs fixes and a seq_buf fix for 6.8:
- Hard-code the inodes for eventfs to the same number for files, and the same number for directories. - Have getdent() not create dentries/inodes in iterate_shared() as now it has hard-coded inode numbers - Use kcalloc() instead of kzalloc() on a list of elements - Fix seq_buf warning and make static work properly. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZak5GxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qvZYAP0ZO4YN9fKnl6Cw1GNCwPtMO13dEg9D mIvwftxX8DuaegD/fQFY9gBc+ZMSCbiWVJBAyfO57NPvHk4S3slwPVuL9gA= =iKJI -----END PGP SIGNATURE----- Merge tag 'eventfs-v6.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull eventfs updates from Steven Rostedt: - Remove "lookup" parameter of create_dir_dentry() and create_file_dentry(). These functions were called by lookup and the readdir logic, where readdir needed it to up the ref count of the dentry but the lookup did not. A "lookup" parameter was passed in to tell it what to do, but this complicated the code. It is better to just always up the ref count and require the caller to decrement it, even for lookup. - Modify the .iterate_shared callback to not use the dcache_readdir() logic and just handle what gets displayed by that one function. This removes the need for eventfs to hijack the file->private_data from the dcache_readdir() "cursor" pointer, and makes the code a bit more sane - Use the root and instance inodes for default ownership. Instead of walking the dentry tree and updating each dentry gid, use the getattr(), setattr() and permission() callbacks to set the ownership and permissions using the root or instance as the default - Some other optimizations with the eventfs iterate_shared logic - Hard-code the inodes for eventfs to the same number for files, and the same number for directories - Have getdent() not create dentries/inodes in iterate_shared() as now it has hard-coded inode numbers - Use kcalloc() instead of kzalloc() on a list of elements - Fix seq_buf warning and make static work properly. * tag 'eventfs-v6.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: seq_buf: Make DECLARE_SEQ_BUF() usable eventfs: Use kcalloc() instead of kzalloc() eventfs: Do not create dentries nor inodes in iterate_shared eventfs: Have the inodes all for files and directories all be the same eventfs: Shortcut eventfs_iterate() by skipping entries already read eventfs: Read ei->entries before ei->children in eventfs_iterate() eventfs: Do ctx->pos update for all iterations in eventfs_iterate() eventfs: Have eventfs_iterate() stop immediately if ei->is_freed is set tracefs/eventfs: Use root and instance inodes as default ownership eventfs: Stop using dcache_readdir() for getdents() eventfs: Remove "lookup" parameter from create_dir/file_dentry() |

tracing updates for 6.8:
- Allow kernel trace instance creation to specify what events are created Inside the kernel, a subsystem may create a tracing instance that it can use to send events to user space. This sub-system may not care about the thousands of events that exist in eventfs. Allow the sub-system to specify what sub-systems of events it cares about, and only those events are exposed to this instance. - Allow the ring buffer to be broken up into bigger sub-buffers than just the architecture page size. A new tracefs file called "buffer_subbuf_size_kb" is created. The user can now specify a minimum size the sub-buffer may be in kilobytes. Note, that the implementation currently make the sub-buffer size a power of 2 pages (1, 2, 4, 8, 16, ...) but the user only writes in kilobyte size, and the sub-buffer will be updated to the next size that it will can accommodate it. If the user writes in 10, it will change the size to be 4 pages on x86 (16K), as that is the next available size that can hold 10K pages. - Update the debug output when a corrupt time is detected in the ring buffer. If the ring buffer detects inconsistent timestamps, there's a debug config options that will dump the contents of the meta data of the sub-buffer that is used for debugging. Add some more information to this dump that helps with debugging. - Add more timestamp debugging checks (only triggers when the config is enabled) - Increase the trace_seq iterator to 2 page sizes. - Allow strings written into tracefs_marker to be larger. Up to just under 2 page sizes (based on what trace_seq can hold). - Increase the trace_maker_raw write to be as big as a sub-buffer can hold. - Remove 32 bit time stamp logic, now that the rb_time_cmpxchg() has been removed. - More selftests were added. - Some code clean ups as well. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZZ8p3BQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6ql2GAQDZg/zlFEiJHyTfWbCIE8pA3T5xbzKo 26TNxIZAxJJZpQEAvGFU5Smy14pG6soEoVMp8B6ZOANbqU8VVamhOL+r+Qw= =0OYG -----END PGP SIGNATURE----- Merge tag 'trace-v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: - Allow kernel trace instance creation to specify what events are created Inside the kernel, a subsystem may create a tracing instance that it can use to send events to user space.

This does not include the actual KVM-side support which will come from the KVM folks. The TDX host interactions with kexec also needs to be ironed out before this is ready for prime time, so this code is currently Kconfig'd off when kexec is on. The majority of the code here is the kernel telling the TDX module which memory to protect and handing some additional memory over to it to use to store TDX module metadata. That sounds pretty simple, but the TDX architecture is rather flexible and it takes quite a bit of back-and-forth to say, "just protect all memory, please." There is also some code tacked on near the end of the series to handle a hardware erratum. The erratum can make software bugs such as a kernel write to TDX-protected memory cause a machine check and masquerade as a real hardware failure.

====================
Netfilter fixes for net
The following batch contains Netfilter fixes for net. Slightly larger
than usual because this batch includes several patches to tighten the
nf_tables control plane to reject inconsistent configuration:
1) Restrict NFTA_SET_POLICY to NFT_SET_POL_PERFORMANCE and
NFT_SET_POL_MEMORY.
2) Bail out if a nf_tables expression registers more than 16 netlink
attributes which is what struct nft_expr_info allows.
3) Bail out if NFT_EXPR_STATEFUL provides no .clone interface, remove
existing fallback to memcpy() when cloning which might accidentally
duplicate memory reference to the same object.
4) Fix br_netfilter interaction with neighbour layer. This requires
three preparation patches:
- Use nf_bridge_get_physinif() in nfnetlink_log
- Use nf_bridge_info_exists() to check in br_netfilter context
is available in nf_queue.
- Pass net to nf_bridge_get_physindev()
And finally, the fix which replaces physindev with physinif
in nf_bridge_info.
Patches from Pavel Tikhomirov.
5) Catch-all deactivation happens in the transaction, hence this
oneliner to check for the next generation. This bug uncovered after
the removal of the _BUSY bit, which happened in set elements back in
summer 2023.
6) Ensure set (total) key length size and concat field length description
is consistent, otherwise bail out.
7) Skip set element with the _DEAD flag on from the netlink dump path.
A tests occasionally shows that dump is mismatching because GC might
lose race to get rid of this element while a netlink dump is in
progress.
8) Reject NFT_SET_CONCAT for field_count < 1.
9) Use IP6_INC_STATS in ipvs to fix preemption BUG splat, patch
from Fedor Pchelkin.
