Joel Granados says:
====================
sysctl: Remove sentinel elements from networking
What?
These commits remove the sentinel element (last empty element) from the
sysctl arrays of all the files under the "net/" directory that register
a sysctl array. The merging of the preparation patches [4] to mainline
allows us to just remove sentinel elements without changing behavior.
This is safe because the sysctl registration code (register_sysctl() and
friends) use the array size in addition to checking for a sentinel [1].
Why?
By removing the sysctl sentinel elements we avoid kernel bloat as
ctl_table arrays get moved out of kernel/sysctl.c into their own
respective subsystems. This move was started long ago to avoid merge
conflicts; the sentinel removal bit came after Mathew Wilcox suggested
it to avoid bloating the kernel by one element as arrays moved out. This
patchset will reduce the overall build time size of the kernel and run
time memory bloat by about ~64 bytes per declared ctl_table array (more
info here [5]).
When are we done?
There are 4 patchest (25 commits [2]) that are still outstanding to
completely remove the sentinels: files under "net/" (this patchset),
files under "kernel/" dir, misc dirs (files under mm/ security/ and
others) and the final set that removes the unneeded check for ->procname
== NULL.
Testing:
* Ran sysctl selftests (./tools/testing/selftests/sysctl/sysctl.sh)
* Ran this through 0-day with no errors or warnings
Savings in vmlinux:
A total of 64 bytes per sentinel is saved after removal; I measured in
x86_64 to give an idea of the aggregated savings. The actual savings
will depend on individual kernel configuration.
* bloat-o-meter
- The "yesall" config saves 3976 bytes (bloat-o-meter output [6])
- A reduced config [3] saves 1263 bytes (bloat-o-meter output [7])
Savings in allocated memory:
None in this set but will occur when the superfluous allocations are
removed from proc_sysctl.c. I include it here for context. The
estimated savings during boot for config [3] are 6272 bytes. See [8]
for how to measure it.
Comments/feedback greatly appreciated
Changes in v6:
- Rebased onto net-next/main.
- Besides re-running my cocci scripts, I ran a new find script [9].
Found 0 hits in net/
- Moved "i" variable declaraction out of for() in sysctl_core_net_init
- Removed forgotten sentinel in mpls_table
- Removed CONFIG_AX25_DAMA_SLAVE guard from net/ax25/ax25_ds_timer.c. It
is not needed because that file is compiled only when
CONFIG_AX25_DAMA_SLAVE is set.
- When traversing smc_table, stop on ARRAY_SIZE instead of ARRAY_SIZE-1.

- Use a table_size variable to keep the value of ARRAY_SIZE
- Separated the original "networking: Remove the now superfluous
sentinel elements from ctl_table arra" into smaller commits to ease
review

This commit comes at the tail end of a greater effort to remove the
empty elements at the end of the ctl_table arrays (sentinels) which will
reduce the overall build time size of the kernel and run time memory
bloat by ~64 bytes per sentinel (further information Link :
https://lore.kernel.org/all/ZO5Yx5JFogGi%2FcBo@bombadil.infradead.org/)
Avoid a buffer overflow when traversing the ctl_table by ensuring that
AX25_MAX_VALUES is the same as the size of ax25_param_table. This is
done with a BUILD_BUG_ON where ax25_param_table is defined and a
CONFIG_AX25_DAMA_SLAVE guard in the unnamed enum definition as well as
in the ax25_dev_device_up and ax25_ds_set_timer functions.
The overflow happened when the sentinel was removed from
ax25_param_table. The sentinel's data element was changed when
CONFIG_AX25_DAMA_SLAVE was undefined. This had no adverse effects as it
still stopped on the sentinel's null procname but needed to be addressed
once the sentinel was removed.

struct net_device shouldn't be embedded into any structure, instead,
the owner should use the priv space to embed their state into net_device.
Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].
Un-embed the net_device from struct iwl_trans_pcie by converting it
into a pointer. Then use the leverage alloc_netdev() to allocate the
net_device object at iwl_trans_pcie_alloc.
The private data of net_device becomes a pointer for the struct
iwl_trans_pcie, so, it is easy to get back to the iwl_trans_pcie parent
given the net_device object.

Before request->channels[] can be used, request->n_channels must be set.
Additionally, address calculations for memory after the "channels" array
need to be calculated from the allocation base ("request") rather than
via the first "out of bounds" index of "channels", otherwise run-time
bounds checking will throw a warning.

Anderson Nascimento reported a use-after-free splat in tcp_twsk_unique()
with nice analysis.
Since commit ec94c2696f0b ("tcp/dccp: avoid one atomic operation for
timewait hashdance"), inet_twsk_hashdance() sets TIME-WAIT socket's
sk_refcnt after putting it into ehash and releasing the bucket lock.
Thus, there is a small race window where other threads could try to
reuse the port during connect() and call sock_hold() in tcp_twsk_unique()
for the TIME-WAIT socket with zero refcnt.
If that happens, the refcnt taken by tcp_twsk_unique() is overwritten
and sock_put() will cause underflow, triggering a real use-after-free
somewhere else.
To avoid the use-after-free, we need to use refcount_inc_not_zero() in
tcp_twsk_unique() and give up on reusing the port if it returns false.
[0]:
refcount_t: addition on 0; use-after-free.

TCP_SYN_RECV state is really special, it is only used by
cross-syn connections, mostly used by fuzzers.
In the following crash [1], syzbot managed to trigger a divide
by zero in tcp_rcv_space_adjust()
A socket makes the following state transitions,
without ever calling tcp_init_transfer(),
meaning tcp_init_buffer_space() is also not called.
TCP_CLOSE
connect()
TCP_SYN_SENT
TCP_SYN_RECV
shutdown() -> tcp_shutdown(sk, SEND_SHUTDOWN)
TCP_FIN_WAIT1
To fix this issue, change tcp_shutdown() to not
perform a TCP_SYN_RECV -> TCP_FIN_WAIT1 transition,
which makes no sense anyway.
When tcp_rcv_state_process() later changes socket state
from TCP_SYN_RECV to TCP_ESTABLISH, then look at
sk->sk_shutdown to finally enter TCP_FIN_WAIT1 state,
and send a FIN packet from a sane socket state.
This means tcp_send_fin() can now be called from BH
context, and must use GFP_ATOMIC allocations.

Since commit a3c53be55c95 ("net: dsa: mv88e6xxx: Support multiple MDIO
busses") mv88e6xxx_default_mdio_bus() has checked that the
return value of list_first_entry() is non-NULL.
This appears to be intended to guard against the list chip->mdios being
empty. However, it is not the correct check as the implementation of
list_first_entry is not designed to return NULL for empty lists.
Instead, use list_first_entry_or_null() which does return NULL if the
list is empty.

Detect packets with ip_summed CHECKSUM_PARTIAL and skip these. These
should not exist, as the test sends individual packets between two
hosts. But if (HW) GRO is on, with randomized content sometimes
subsequent packets can be coalesced.
In this case the GSO packet checksum is converted to a pseudo checksum
in anticipation of sending out as TSO/USO. So the field will not match
the expected value.
Do not count these as test errors.

We're a bit too loose with error checking for background
processes. cmd() completely ignores the fail argument
passed to the constructor if background is True.
Default to checking for errors if process is not terminated
explicitly. Caller can override with True / False.
For bkg() the processing step is called magically by __exit__
so record the value passed in the constructor.

In case any unsupported control flags are masked,
flow_rule_is_supp_control_flags() sets a NL extended

We previously would call btrfs_check_leaf() if we had the check
integrity code enabled, which meant that we could only run the extended
leaf checks if we had WRITTEN set on the header flags.
This leaves a gap in our checking, because we could end up with
corruption on disk where WRITTEN isn't set on the leaf, and then the
extended leaf checks don't get run which we rely on to validate all of
the item pointers to make sure we don't access memory outside of the
extent buffer.
However, since 732fab95abe2 ("btrfs: check-integrity: remove
CONFIG_BTRFS_FS_CHECK_INTEGRITY option") we no longer call
btrfs_check_leaf() from btrfs_mark_buffer_dirty(), which means we only
ever call it on blocks that are being written out, and thus have WRITTEN
set, or that are being read in, which should have WRITTEN set.
Add checks to make sure we have WRITTEN set appropriately, and then make
sure __btrfs_check_leaf() always does the item checking. This will
protect us from file systems that have been corrupted and no longer have
WRITTEN set on some of the blocks.
This was hit on a crafted image tweaking the WRITTEN bit and reported by
KASAN as out-of-bound access in the eb accessors. The example is a dir
item at the end of an eb.

[BUG]
After kernel commit 86211eea8ae1 ("btrfs: qgroup: validate
btrfs_qgroup_inherit parameter"), user space tool snapper will fail to
create snapshot using its timeline feature.
[CAUSE]
It turns out that, if using timeline snapper would unconditionally pass
btrfs_qgroup_inherit parameter (assigning the new snapshot to qgroup 1/0)
for snapshot creation.
In that case, since qgroup is disabled there would be no qgroup 1/0, and
btrfs_qgroup_check_inherit() would return -ENOENT and fail the whole
snapshot creation.
[FIX]
Just skip the check if qgroup is not enabled.
This is to keep the older behavior for user space tools, as if the
kernel behavior changed for user space, it is a regression of kernel.
Thankfully snapper is also fixing the behavior by detecting if qgroup is
running in the first place, so the effect should not be that huge.

With recent sanity checks for topology information added, there are now
warnings issued for APs when running as a Xen PV guest:
[Firmware Bug]: CPU 1: APIC ID mismatch. CPUID: 0x0000 APIC: 0x0001
This is due to the initial APIC ID obtained via CPUID for PV guests is
always 0.
Avoid the warnings by synthesizing the CPUID data to contain the same
initial APIC ID as xen_pv_smp_config() is using for registering the
APIC IDs of all CPUs.

Contrary to i915, in xe ADL-N is kept as a different platform, not a
subplatform of ADL-P. Since the display side doesn't need to
differentiate between P and N, i.e. IS_ALDERLAKE_P_N() is never called,
just fixup the compat header to check for both P and N.
Moving ADL-N to be a subplatform would be more complex as the firmware
loading in xe only handles platforms, not subplatforms, as going forward
the direction is to check on IP version rather than
platforms/subplatforms.
Fix warning when initializing display:
xe 0000:00:02.0: [drm:intel_pch_type [xe]] Found Alder Lake PCH
------------[ cut here ]------------
xe 0000:00:02.0: drm_WARN_ON(!((dev_priv)->info.platform == XE_ALDERLAKE_S) && !((dev_priv)->info.platform == XE_ALDERLAKE_P))
And wrong paths being taken on the display side.

"Two driver fixes:
- The firewire-ohci driver for 1394 OHCI hardware does not fill time
stamp for response packet when handling asynchronous transaction to
local destination. This brings an inconvenience that the response
packet is not equivalent between the transaction to local and
remote. It is fixed by fulfilling the time stamp with hardware
time. The fix should be applied to Linux kernel v6.5 or later as
well.
- The nosy driver for Texas Instruments TSB12LV21A (PCILynx) has
long-standing issue about the behaviour when user space application
passes less size of buffer than expected. It is fixed by returning
zero according to the convention of UNIX-like systems"

The topology core expects the boot APIC to be registered from earhy APIC
detection first and then again when the firmware tables are evaluated. This
is used for detecting the real BSP CPU on a kexec kernel.
The recent conversion of XEN/PV to register fake APIC IDs failed to
register the boot CPU APIC correctly as it only registers it once. This
causes the BSP detection mechanism to trigger wrongly:
CPU topo: Boot CPU APIC ID not the first enumerated APIC ID: 0 > 1
Additionally this results in one CPU being ignored.
Register the boot CPU APIC twice so that the XEN/PV fake enumeration
behaves like real firmware.

Michael Chan says:
====================
bnxt_en: Updates for net-next
The first patch converts the sw_stats field in the completion
ring structure to a pointer. This allows the group of
completion rings using the same MSIX to share the same sw_stats
structure. Prior to this, the correct completion ring must be
used to count packets.
The next four patches remove the RTNL lock when calling the RoCE
driver for asynchronous stop and start during error recovery and
firmware reset. The RTNL ilock is replaced with a private mutex
used to synchronize RoCE register, unregister, stop, and start.
The last patch adds VF PCI IDs for the 5760X chips.
v2: Dropped patch #1 from v1. Will work with David to get that
patch in separately.

No driver logic changes are required to support the VFs, so just add
the VF PCI ID.

In the error recovery path (AER, firmware recovery, etc), the
driver notifies the RoCE driver via ULP_STOP before the reset
and via ULP_START after the reset, all under RTNL_LOCK. The
RoCE driver can take a long time if there are a lot of QPs to
destroy, so it is not ideal to hold the global RTNL lock.
Rely on the new en_dev_lock mutex instead for ULP_STOP and
ULP_START. For the most part, we move the ULP_STOP call before
we take the RTNL lock and move the ULP_START after RTNL unlock.
Note that SRIOV re-enablement must be done after ULP_START
or RoCE on the VFs will not resume properly after reset.
The one scenario in bnxt_hwrm_if_change() where the RTNL lock
is already taken in the .ndo_open() context requires the ULP
restart to be deferred to the bnxt_sp_task() workqueue.

The current scheme relies heavily on the RTNL lock for all ULP
operations between the L2 and the RoCE driver. Add a new en_dev_lock
mutex so that the asynchronous ULP_STOP and ULP_START operations
can be serialized with bnxt_register_dev() and bnxt_unregister_dev()
calls without relying on the RTNL lock. The next patch will remove
the RTNL lock from the ULP_STOP and ULP_START calls.
