disable_irq() after request_irq() still has a time gap in which
interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will
disable IRQ auto-enable when request IRQ.

Both bareudp_xmit_skb() and bareudp6_xmit_skb() read their skb's inner
IP header to get its ECN value (with ip_tunnel_ecn_encap()). Therefore
we need to ensure that the inner IP header is part of the skb's linear
data.

Bareudp reads the inner IP header to get the ECN value. Therefore, it
needs to ensure that it's part of the skb's linear data.
This is similar to the vxlan and geneve fixes for that same problem:
* commit f7789419137b ("vxlan: Pull inner IP header in vxlan_rcv().")
* commit 1ca1ba465e55 ("geneve: make sure to pull inner header in

====================
pull-request: bpf-next 2024-09-11
We've added 12 non-merge commits during the last 16 day(s) which contain
a total of 20 files changed, 228 insertions(+), 30 deletions(-).
There's a minor merge conflict in drivers/net/netkit.c:
00d066a4d4ed ("netdev_features: convert NETIF_F_LLTX to dev->lltx")
d96608794889 ("netkit: Disable netpoll support")
The main changes are:
1) Enable bpf_dynptr_from_skb for tp_btf such that this can be used
to easily parse skbs in BPF programs attached to tracepoints,
from Philo Lu.
2) Add a cond_resched() point in BPF's sock_hash_free() as there have
been several syzbot soft lockup reports recently, from Eric Dumazet.
3) Fix xsk_buff_can_alloc() to account for queue_empty_descs which
got noticed when zero copy ice driver started to use it,
from Maciej Fijalkowski.
4) Move the xdp:xdp_cpumap_kthread tracepoint before cpumap pushes skbs
up via netif_receive_skb_list() to better measure latencies,
from Daniel Xu.
5) Follow-up to disable netpoll support from netkit, from Daniel Borkmann.
6) Improve xsk selftests to not assume a fixed MAX_SKB_FRAGS of 17 but
instead gather the actual value via /proc/sys/net/core/max_skb_frags,
also from Maciej Fijalkowski.

Update lpfc to revision 14.4.0.5
This patch set contains bug fixes related to HBA state clean ups, FCP
discovery on older adapters, kref imbalances, log message improvements,
and support for a new diagnostic loopback testing mode.
The patches were cut against Martin's 6.12/scsi-queue tree.

The VMID feature adds an extra application services header to each frame.
As such, the loopback test path is updated to accommodate the extra
application header.
Changes include filling in APPID and WQES bit fields for XMIT_SEQUENCE64
commands, a special loopback source APPID for verifying received loopback
data matches what is sent, and increasing ELS WQ size to accommodate the
APPID field in loopback test mode.

Revise certain log messages marked as KERN_ERR LOG_TRACE_EVENT to
KERN_WARNING and use the lpfc_vlog_msg() macro to still log the event. The
benefit is that events of interest are still logged and the entire trace
buffer is not dumped with extraneous logging information when using default
lpfc_log_verbose driver parameter settings.
Also, delete the keyword "fail" from such log messages as they aren't
really causes for concern. The log messages are more for warnings to a SAN
admin about SAN activity.

With a FLOGI outstanding and loss of physical link connection to the fabric
for the duration of dev_loss_tmo, there is a fabric ndlp kref imbalance
that decrements the kref and sets the NLP_IN_RECOV_POST_DEV_LOSS flag at
the same time.
The issue is that when the FLOGI completion routine executes, the fabric
ndlp could already be freed because of the final kref put from the
dev_loss_tmo handler. Fix by early returning before the ndlp kref put if
the ndlp is deemed a candidate for NLP_IN_RECOV_POST_DEV_LOSS in the FLOGI
completion routine.

It's possible for the driver to send a CMF_SYNC_WQE to nonresponsive
firmware during reset of the adapter. The phba link_state conditional
check is currently a strict == LPFC_LINK_DOWN, which does not cover
initialization states before reaching the LPFC_LINK_UP state.
Update the phba->link_state conditional to < LPFC_LINK_UP so that all
initialization states are covered before allowing sending CMF_SYNC_WQE.
Update taking of the hbalock to be during this link_state check as well.

During HBA stress testing, a spam of received PLOGIs exposes a resource
recovery bug causing leakage of lpfc_sqlq entries from the global
phba->sli4_hba.lpfc_els_sgl_list.
The issue is in lpfc_els_flush_cmd(), where the driver attempts to recover
outstanding ELS sgls when walking the txcmplq. Only CMD_ELS_REQUEST64_CRs
and CMD_GEN_REQUEST64_CRs are added to the abort and cancel lists. A check
for CMD_XMIT_ELS_RSP64_WQE is missing in order to recover LS_ACC usages of
the phba->sli4_hba.lpfc_els_sgl_list too.
Fix by adding CMD_XMIT_ELS_RSP64_WQE as part of the txcmplq walk when
adding WQEs to the abort and cancel list in lpfc_els_flush_cmd(). Also,
update naming convention from CRs to WQEs.

During controller transitioning to READY state, if the controller is found
in transient states ("becoming ready" or "reset requested"), driver waits
for 510 secs even if the controller transitions out of these states
early. This causes an unnecessary delay of 510 secs in the overall firmware
initialization sequence.
Poll the controller state periodically (every 100 milliseconds) while
waiting for the controller to come out of the mentioned transient
states. Once the controller transits out of the transient states, come out
of the wait loop.

- `linklocal_allowance_exceeded`
- `pps_allowance_exceeded`
This patch adds a new metric named:
`conntrack_allowance_available`.
Information about these metrics is available in [1].
In addition, the interface between the driver and the

There are some scenarios that can occur, such as performing an upgrade of
the virtual I/O server, where the supported max transfer of the backing
device for an ibmvfc HBA can change. If the max transfer of the backing
device decreases, this can cause issues with previously discovered
LUNs. This patch accomplishes two things. First, it changes the default
ibmvfc max transfer value to 1MB. This is generally supported by all
backing devices, which should mitigate this issue out of the box. Secondly,
it adds a module parameter, enabling a user to increase the max transfer
value to values that are larger than 1MB, as long as they have configured
these larger values on the virtual I/O server as well.

A previous change was introduced to prevent data loss during a power-on
reset when a tape is present inside the drive. This commit set the
"pos_unknown" flag to true to avoid operations that could compromise data
by performing actions from an untracked position. The relevant change is
commit 9604eea5bd3a ("scsi: st: Add third party poweron reset handling")
As a consequence of this change, a new issue has surfaced: the driver now
returns an "Input/output error" even for empty drives when the drive, host,
or bus is reset. This issue stems from the "flush_buffer" function, which
first checks whether the "pos_unknown" flag is set. If the flag is set, the
user will encounter an "Input/output error" until the tape position is
known again. This behavior differs from the previous implementation, where
empty drives were not affected at system start up time, allowing tape
software to send commands to the driver to retrieve the drive's status and
other information.
The current behavior prioritizes the "pos_unknown" flag over the
"ST_NO_TAPE" status, leading to issues for software that detects drives
during system startup. This software will receive an "Input/output error"
until a tape is loaded and its position is known.
To resolve this, the "ST_NO_TAPE" status should take priority when the
drive is empty, allowing communication with the drive following a power-on
reset. At the same time, the change should continue to protect data by
maintaining the "pos_unknown" flag when the drive contains a tape and its
position is unknown.

When we fail to map a BO in the GGTT, we release our GGTT node
