net: usb: smsc95xx: fix changing LED_SEL bit value updated from EEPROM

net: usb: smsc95xx: fix changing LED_SEL bit value updated from EEPROM

[ Upstream commit 52a2f0608366a629d43dacd3191039c95fef74ba ]

LED Select (LED_SEL) bit in the LED General Purpose IO Configuration
register is used to determine the functionality of external LED pins
(Speed Indicator, Link and Activity Indicator, Full Duplex Link
Indicator). The default value for this bit is 0 when no EEPROM is
present. If a EEPROM is present, the default value is the value of the
LED Select bit in the Configuration Flags of the EEPROM. A USB Reset or
Lite Reset (LRST) will cause this bit to be restored to the image value
last loaded from EEPROM, or to be set to 0 if no EEPROM is present.

While configuring the dual purpose GPIO/LED pins to LED outputs in the
LED General Purpose IO Configuration register, the LED_SEL bit is changed
as 0 and resulting the configured value from the EEPROM is cleared. The
issue is fixed by using read-modify-write approach.

net: usb: smsc95xx: stop lying about skb->truesize

net: usb: smsc95xx: stop lying about skb->truesize

[ Upstream commit d50729f1d60bca822ef6d9c1a5fb28d486bd7593 ]

Some usb drivers try to set small skb->truesize and break
core networking stacks.

In this patch, I removed one of the skb->truesize override.

I also replaced one skb_clone() by an allocation of a fresh
and small skb, to get minimally sized skbs, like we did
in commit 1e2c61172342 ("net: cdc_ncm: reduce skb truesize
in rx path") and 4ce62d5b2f7a ("net: usb: ax88179_178a:
stop lying about skb->truesize")

v3: also fix a sparse error ( https://lore.kernel.org/oe-kbuild-all/202405091310.KvncIecx-lkp@intel.com/ )
v2: leave the skb_trim() game because smsc95xx_rx_csum_offload()
needs the csum part. (Jakub)
While we are it, use get_unaligned() in smsc95xx_rx_csum_offload().

=====================================================

Similar to e9c65989920f ("net: usb: smsc75xx: Fix uninit-value access in
__smsc75xx_read_reg"), this issue is caused because usbnet_read_cmd() reads
less bytes than requested (zero byte in the reproducer). In this case,
'buf' is not properly filled.

This patch fixes the issue by returning -ENODATA if usbnet_read_cmd() reads
less bytes than requested.

sysbot reported similar uninit-value access issue [2]. The root cause is
the same as mentioned above, and this patch addresses it as well.

Merge tag 'net-6.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
"Including fixes from bluetooth, netfilter, WiFi.

Feels like an up-tick in regression fixes, mostly for older releases.
The hfsc fix, tcp_disconnect() and Intel WWAN fixes stand out as
fairly clear-cut user reported regressions. The mlx5 DMA bug was
causing strife for 390x folks. The fixes themselves are not
particularly scary, tho. No open investigations / outstanding reports
at the time of writing.

Current release - regressions:

- eth: mlx5: perform DMA operations in the right locations, make
devices usable on s390x, again

- sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner
curve, previous fix of rejecting invalid config broke some scripts

- rfkill: reduce data->mtx scope in rfkill_fop_open, avoid deadlock

- revert "ethtool: Fix mod state of verbose no_mask bitset", needs
more work

Current release - new code bugs:

- tcp: fix listen() warning with v4-mapped-v6 address

Previous releases - regressions:

- tcp: allow tcp_disconnect() again when threads are waiting, it was
denied to plug a constant source of bugs but turns out .NET depends
on it

- eth: mlx5: fix double-free if buffer refill fails under OOM

- revert "net: wwan: iosm: enable runtime pm support for 7560", it's
causing regressions and the WWAN team at Intel disappeared

- tcp: tsq: relax tcp_small_queue_check() when rtx queue contains a
single skb, fix single-stream perf regression on some devices

Previous releases - always broken:

- Bluetooth:
- fix issues in legacy BR/EDR PIN code pairing
- correctly bounds check and pad HCI_MON_NEW_INDEX name

- netfilter:
- more fixes / follow ups for the large "commit protocol" rework,
which went in as a fix to 6.5
- fix null-derefs on netlink attrs which user may not pass in

- tcp: fix excessive TLP and RACK timeouts from HZ rounding (bless
Debian for keeping HZ=250 alive)

- net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation, prevent
letting frankenstein UDP super-frames from getting into the stack

- net: fix interface altnames when ifc moves to a new namespace

- eth: qed: fix the size of the RX buffers

KVM/arm64 updates for 6.4

- Numerous fixes for the pathological lock inversion issue that
plagued KVM/arm64 since... forever.

- New framework allowing SMCCC-compliant hypercalls to be forwarded
to userspace, hopefully paving the way for some more features
being moved to VMMs rather than be implemented in the kernel.

- Large rework of the timer code to allow a VM-wide offset to be
applied to both virtual and physical counters as well as a
per-timer, per-vcpu offset that complements the global one.
This last part allows the NV timer code to be implemented on
top.

- A small set of fixes to make sure that we don't change anything
affecting the EL1&0 translation regime just after having having
taken an exception to EL2 until we have executed a DSB. This
ensures that speculative walks started in EL1&0 have completed.

- The usual selftest fixes and improvements.

RK8600/RK8601 are quite similar to the FAN53555 regulators.

RK8602/RK8603 are a bit different, having a wider output voltage
selection range, from 0.5 V to 1.5 V in 6.25 mV steps. They are used
in the Rock 5B board to power the ARM Cortex-A76 cores and the NPU.
