Pull networking fixes from Paolo Abeni:
"Including fixes from bpf, netfilter and WiFi.
Jakub is doing a lot of work to include the self-tests in our CI, as a
result a significant amount of self-tests related fixes is flowing in
(and will likely continue in the next few weeks).
Current release - regressions:
- bpf: fix a kernel crash for the riscv 64 JIT
- bnxt_en: fix memory leak in bnxt_hwrm_get_rings()
- revert "net: macsec: use skb_ensure_writable_head_tail to expand
the skb"
Previous releases - regressions:
- core: fix removing a namespace with conflicting altnames
- tc/flower: fix chain template offload memory leak
- tcp:
- make sure init the accept_queue's spinlocks once
- fix autocork on CPUs with weak memory model
- udp: fix busy polling
- mlx5e:
- fix out-of-bound read in port timestamping
- fix peer flow lists corruption
- iwlwifi: fix a memory corruption
Previous releases - always broken:
- netfilter:
- nft_chain_filter: handle NETDEV_UNREGISTER for inet/ingress
basechain
- nft_limit: reject configurations that cause integer overflow
- bpf: fix bpf_xdp_adjust_tail() with XSK zero-copy mbuf, avoiding a
NULL pointer dereference upon shrinking
- llc: make llc_ui_sendmsg() more robust against bonding changes
- smc: fix illegal rmb_desc access in SMC-D connection dump
- dpll: fix pin dump crash for rebound module
- bnxt_en: fix possible crash after creating sw mqprio TCs
- hv_netvsc: calculate correct ring size when PAGE_SIZE is not 4kB
Misc:
- several self-tests fixes for better integration with the netdev CI
- added several missing modules descriptions"

The fill ring of the XDP socket may contain not enough buffers to
completey fill the RX queue during socket creation. In this case the
flag XDP_RING_NEED_WAKEUP is not set as this flag is only set if the RX
queue is not completely filled during polling.
Set XDP_RING_NEED_WAKEUP flag also if RX queue is not completely filled
during XDP socket creation.

The RX data buffer includes the FCS. The FCS is already stripped for the
normal data path. But for the XDP data path the FCS is included and
acts like additional/useless data.
Remove the FCS from the RX data buffer also for XDP.

When kcalloc() for ft->g succeeds but kvzalloc() for in fails,
fs_any_create_groups() will free ft->g. However, its caller
fs_any_create_table() will free ft->g again through calling
mlx5e_destroy_flow_table(), which will lead to a double-free.
Fix this by setting ft->g to NULL in fs_any_create_groups().

When `in` allocated by kvzalloc fails, arfs_create_groups will free
ft->g and return an error. However, arfs_create_table, the only caller of
arfs_create_groups, will hold this error and call to
mlx5e_destroy_flow_table, in which the ft->g will be freed again.

XFRM stack doesn't prevent from users to configure replay window
in TX side and strongswan sets replay_window to be 1. It causes
to failures in validation logic when trying to offload the SA.
Replay window is not relevant in TX side and should be ignored.

When FW provides ICM addresses for drop RX/TX, the provided capability
is 64 bits that contain its GVMI as well as the ICM address itself.
In case of TX DROP this GVMI is different from the GVMI that the
domain is operating on.

The cited change refactored mlx5e_tc_del_fdb_peer_flow() to only clear DUP
flag when list of peer flows has become empty. However, if any concurrent
user holds a reference to a peer flow (for example, the neighbor update
workqueue task is updating peer flow's parent encap entry concurrently),
then the flow will not be removed from the peer list and, consecutively,
DUP flag will remain set. Since mlx5e_tc_del_fdb_peers_flow() calls
mlx5e_tc_del_fdb_peer_flow() for every possible peer index the algorithm
will try to remove the flow from eswitch instances that it has never peered
with causing either NULL pointer dereference when trying to remove the flow
peer list head of peer_index that was never initialized or a warning if the
list debug config is enabled[0].
Fix the issue by always removing the peer flow from the list even when not
releasing the last reference to it.

The processing of traffic in hairpin queues occurs in HW/FW and does not
involve the cpus, hence the upper bound on max num channels does not
apply to them. Using this bound for the hairpin RQT max_table_size is
wrong. It could be too small, and cause the error below [1]. As the
RQT size provided on init does not get modified later, use the same
value for both actual and max table sizes.

Indirection (*) is of lower precedence than postfix increment (++). Logic
in napi_poll context would cause an out-of-bound read by first increment
the pointer address by byte address space and then dereference the value.
Rather, the intended logic was to dereference first and then increment the
underlying value.

The cited commit moved the code of mlx5e_create_tises() and changed the
loop to create TISes over MLX5_MAX_PORTS constant value, instead of
getting the correct lag ports supported by the device, which can cause
FW errors on devices with less than MLX5_MAX_PORTS ports.
Change that back to mlx5e_get_num_lag_ports(mdev).
Also IPoIB interfaces create there own TISes, they don't use the eth
TISes, pass a flag to indicate that.
This fixes the following errors that might appear in kernel log:

i40e support XDP multi-buffer so it is supposed to use
__xdp_rxq_info_reg() instead of xdp_rxq_info_reg() and set the
frag_size. It can not be simply converted at existing callsite because
rx_buf_len could be un-initialized, so let us register xdp_rxq_info
within i40e_configure_rx_ring(), which happen to be called with already
initialized rx_buf_len value.
Commit 5180ff1364bc ("i40e: use int for i40e_status") converted 'err' to
int, so two variables to deal with return codes are not needed within
i40e_configure_rx_ring(). Remove 'ret' and use 'err' to handle status
from xdp_rxq_info registration.

Ice and i40e ZC drivers currently set offset of a frag within
skb_shared_info to 0, which is incorrect. xdp_buffs that come from
xsk_buff_pool always have 256 bytes of a headroom, so they need to be
taken into account to retrieve xdp_buff::data via skb_frag_address().
Otherwise, bpf_xdp_frags_increase_tail() would be starting its job from
xdp_buff::data_hard_start which would result in overwriting existing
payload.

xdp_rxq_info struct can be registered by drivers via two functions -
xdp_rxq_info_reg() and __xdp_rxq_info_reg(). The latter one allows
drivers that support XDP multi-buffer to set up xdp_rxq_info::frag_size
which in turn will make it possible to grow the packet via
bpf_xdp_adjust_tail() BPF helper.
Currently, ice registers xdp_rxq_info in two spots:
1) ice_setup_rx_ring() // via xdp_rxq_info_reg(), BUG
2) ice_vsi_cfg_rxq() // via __xdp_rxq_info_reg(), OK
Cited commit under fixes tag took care of setting up frag_size and
updated registration scheme in 2) but it did not help as
1) is called before 2) and as shown above it uses old registration
function. This means that 2) sees that xdp_rxq_info is already
registered and never calls __xdp_rxq_info_reg() which leaves us with
xdp_rxq_info::frag_size being set to 0.
To fix this misbehavior, simply remove xdp_rxq_info_reg() call from
ice_setup_rx_ring().

XDP programs can shrink packets by calling the bpf_xdp_adjust_tail()
helper function. For multi-buffer packets this may lead to reduction of
frag count stored in skb_shared_info area of the xdp_buff struct. This
results in issues with the current handling of XDP_PASS and XDP_DROP
cases.
For XDP_PASS, currently skb is being built using frag count of
xdp_buffer before it was processed by XDP prog and thus will result in
an inconsistent skb when frag count gets reduced by XDP prog. To fix
this, get correct frag count while building the skb instead of using
pre-obtained frag count.
For XDP_DROP, current page recycling logic will not reuse the page but
instead will adjust the pagecnt_bias so that the page can be freed. This
again results in inconsistent behavior as the page refcnt has already
been changed by the helper while freeing the frag(s) as part of

Fix an OOM panic in XDP_DRV mode when a XDP program shrinks a
multi-buffer packet by 4k bytes and then redirects it to an AF_XDP
socket.
Since support for handling multi-buffer frames was added to XDP, usage
of bpf_xdp_adjust_tail() helper within XDP program can free the page
that given fragment occupies and in turn decrease the fragment count
within skb_shared_info that is embedded in xdp_buff struct. In current
ice driver codebase, it can become problematic when page recycling logic
decides not to reuse the page. In such case, __page_frag_cache_drain()
is used with ice_rx_buf::pagecnt_bias that was not adjusted after
refcount of page was changed by XDP prog which in turn does not drain
the refcount to 0 and page is never freed.
To address this, let us store the count of frags before the XDP program
was executed on Rx ring struct. This will be used to compare with
current frag count from skb_shared_info embedded in xdp_buff. A smaller
value in the latter indicates that XDP prog freed frag(s). Then, for
given delta decrement pagecnt_bias for XDP_DROP verdict.
While at it, let us also handle the EOP frag within
ice_set_rx_bufs_act() to make our life easier, so all of the adjustments
needed to be applied against freed frags are performed in the single
place.

XDP multi-buffer support introduced XDP_FLAGS_HAS_FRAGS flag that is
used by drivers to notify data path whether xdp_buff contains fragments
or not. Data path looks up mentioned flag on first buffer that occupies
the linear part of xdp_buff, so drivers only modify it there. This is
sufficient for SKB and XDP_DRV modes as usually xdp_buff is allocated on
stack or it resides within struct representing driver's queue and
fragments are carried via skb_frag_t structs. IOW, we are dealing with
only one xdp_buff.
ZC mode though relies on list of xdp_buff structs that is carried via
xsk_buff_pool::xskb_list, so ZC data path has to make sure that
fragments do *not* have XDP_FLAGS_HAS_FRAGS set. Otherwise,
xsk_buff_free() could misbehave if it would be executed against xdp_buff
that carries a frag with XDP_FLAGS_HAS_FRAGS flag set. Such scenario can
take place when within supplied XDP program bpf_xdp_adjust_tail() is
used with negative offset that would in turn release the tail fragment
from multi-buffer frame.
Calling xsk_buff_free() on tail fragment with XDP_FLAGS_HAS_FRAGS would
result in releasing all the nodes from xskb_list that were produced by
driver before XDP program execution, which is not what is intended -
only tail fragment should be deleted from xskb_list and then it should
be put onto xsk_buff_pool::free_list. Such multi-buffer frame will never
make it up to user space, so from AF_XDP application POV there would be
no traffic running, however due to free_list getting constantly new
nodes, driver will be able to feed HW Rx queue with recycled buffers.
Bottom line is that instead of traffic being redirected to user space,
it would be continuously dropped.
To fix this, let us clear the mentioned flag on xsk_buff_pool side
during xdp_buff initialization, which is what should have been done
right from the start of XSK multi-buffer support.

When repeatedly changing the interface link speed using the command below:
ethtool -s eth0 speed 100 duplex full
ethtool -s eth0 speed 1000 duplex full
The following errors may sometimes be reported by the ARM SMMU driver:
[ 5395.035364] fec 5b040000.ethernet eth0: Link is Down
[ 5395.039255] arm-smmu 51400000.iommu: Unhandled context fault:

[ 5398.108460] fec 5b040000.ethernet eth0: Link is Up - 100Mbps/Full -
flow control off
It is identified that the FEC driver does not properly stop the TX queue
during the link speed transitions, and this results in the invalid virtual
I/O address translations from the SMMU and causes the context faults.

In fjes_hw_setup, it allocates several memory and delay the deallocation
to the fjes_hw_exit in fjes_probe through the following call chain:
fjes_probe
|-> fjes_hw_init
|-> fjes_hw_setup
|-> fjes_hw_exit
However, when fjes_hw_setup fails, fjes_hw_exit won't be called and thus
all the resources allocated in fjes_hw_setup will be leaked. In this
patch, we free those resources in fjes_hw_setup and prevents such leaks.

otherwise the synopsys_id value may be read out wrong,
because the GMAC_VERSION register might still be in reset
state, for at least 1 us after the reset is de-asserted.
Add a wait for 10 us before continuing to be on the safe side.
> From what have you got that delay value?
Just try and error, with very old linux versions and old gcc versions
the synopsys_id was read out correctly most of the time (but not always),
with recent linux versions and recnet gcc versions it was read out
wrongly most of the time, but again not always.
I don't have access to the VHDL code in question, so I cannot
tell why it takes so long to get the correct values, I also do not
have more than a few hardware samples, so I cannot tell how long
this timeout must be in worst case.
Experimentally I can tell that the register is read several times
as zero immediately after the reset is de-asserted, also adding several
no-ops is not enough, adding a printk is enough, also udelay(1) seems to
be enough but I tried that not very often, and I have not access to many
hardware samples to be 100% sure about the necessary delay.
And since the udelay here is only executed once per device instance,
it seems acceptable to delay the boot for 10 us.
BTW: my hardware's synopsys id is 0x37.

Current code in netvsc_drv_init() incorrectly assumes that PAGE_SIZE
is 4 Kbytes, which is wrong on ARM64 with 16K or 64K page size. As a
result, the default VMBus ring buffer size on ARM64 with 64K page size
is 8 Mbytes instead of the expected 512 Kbytes. While this doesn't break
anything, a typical VM with 8 vCPUs and 8 netvsc channels wastes 120
Mbytes (8 channels * 2 ring buffers/channel * 7.5 Mbytes/ring buffer).
Unfortunately, the module parameter specifying the ring buffer size
is in units of 4 Kbyte pages. Ideally, it should be in units that
are independent of PAGE_SIZE, but backwards compatibility prevents
changing that now.
Fix this by having netvsc_drv_init() hardcode 4096 instead of using
PAGE_SIZE when calculating the ring buffer size in bytes. Also
use the VMBUS_RING_SIZE macro to ensure proper alignment when running
with page size larger than 4K.

This reverts commit b34ab3527b9622ca4910df24ff5beed5aa66c6b5.
Using skb_ensure_writable_head_tail without a call to skb_unshare causes
the MACsec stack to operate on the original skb rather than a copy in the
macsec_encrypt path. This causes the buffer to be exceeded in space, and
leads to warnings generated by skb_put operations. Opting to revert this
change since skb_copy_expand is more efficient than
skb_ensure_writable_head_tail followed by a call to skb_unshare.

iwl_fw_ini_trigger_tlv::data is a pointer to a __le32, which means that
if we copy to iwl_fw_ini_trigger_tlv::data + offset while offset is in
bytes, we'll write past the buffer.

mac80211 started to delete debugfs entries in certain cases, causing a
ath11k to crash when it tried to delete the entries later. Fix this by
relying on mac80211 to delete the entries when appropriate and adding
them from the vif_add_debugfs handler.

GCC 13.2 warns:
drivers/net/wireless/intersil/p54/fwio.c:128:34: warning: '%s' directive output may be truncated writing up to 39 bytes into a region of size 32 [-Wformat-truncation=]
drivers/net/wireless/intersil/p54/fwio.c:128:33: note: directive argument in the range [0, 16777215]
drivers/net/wireless/intersil/p54/fwio.c:128:33: note: directive argument in the range [0, 255]
drivers/net/wireless/intersil/p54/fwio.c:127:17: note: 'snprintf' output between 7 and 52 bytes into a destination of size 32
The issue here is that wiphy->fw_version is 32 bytes and in theory the string
we try to place there can be 39 bytes. wiphy->fw_version is used for providing
the firmware version to user space via ethtool, so not really important.
fw_version in theory can be 24 bytes but in practise it's shorter, so even if
print only 19 bytes via ethtool there should not be any practical difference.
I did consider removing fw_var from the string altogether or making the maximum
length for fw_version 19 bytes, but chose this approach as it was the least
intrusive.
Compile tested only.

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.

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.

The commit 8ae1aff0b331 ("tuntap: split out XDP logic") includes
dropped counter for XDP_DROP, XDP_ABORTED, and invalid XDP actions.
Unfortunately, that commit missed the dropped counter when error
occurs during XDP_TX and XDP_REDIRECT actions. This patch fixes
this issue.
