[ Upstream commit f0aa59a33d2ac2267d260fe21eaf92500df8e7b4 ]
Some USB-SATA adapters have broken behavior when an unsupported VPD page is
probed: Depending on the VPD page number, a 4-byte header with a valid VPD
page number but with a 0 length is returned. Currently, scsi_vpd_inquiry()
only checks that the page number is valid to determine if the page is
valid, which results in receiving only the 4-byte header for the
non-existent page. This error manifests itself very often with page 0xb9
for the Concurrent Positioning Ranges detection done by sd_read_cpr(),
resulting in the following error message:
sd 0:0:0:0: [sda] Invalid Concurrent Positioning Ranges VPD page
Prevent such misleading error message by adding a check in
scsi_vpd_inquiry() to verify that the page length is not 0.

While using i219-LM card currently it was only possible to achieve
about 60% of maximum speed due to regression introduced in Linux 5.8.
This was caused by TSO not being disabled by default despite commit
f29801030ac6 ("e1000e: Disable TSO for buffer overrun workaround").
Fix that by disabling TSO during driver probe.

[ Upstream commit 1f64757ee2bb22a93ec89b4c71707297e8cca0ba ]
During initialization the driver issues a reset command via its command
interface in order to remove previous configuration from the device.
After issuing the reset, the driver waits for 200ms before polling on
the "system_status" register using memory-mapped IO until the device
reaches a ready state (0x5E). The wait is necessary because the reset
command only triggers the reset, but the reset itself happens
asynchronously. If the driver starts polling too soon, the read of the
"system_status" register will never return and the system will crash
[1].
The issue was discovered when the device was flashed with a development
firmware version where the reset routine took longer to complete. The
issue was fixed in the firmware, but it exposed the fact that the
current wait time is borderline.
Fix by increasing the wait time from 200ms to 400ms. With this patch and
the buggy firmware version, the issue did not reproduce in 10 reboots
whereas without the patch the issue is reproduced quite consistently.

[ Upstream commit c484fcc058bada604d7e4e5228d4affb646ddbc2 ]
When a net device is put administratively up, its 'IFF_UP' flag is set
(if not set already) and a 'NETDEV_UP' notification is emitted, which
causes the 8021q driver to add VLAN ID 0 on the device. The reverse
happens when a net device is put administratively down.
When changing the type of a bond to Ethernet, its 'IFF_UP' flag is
incorrectly cleared, resulting in the kernel skipping the above process
and VLAN ID 0 being leaked [1].
Fix by restoring the flag when changing the type to Ethernet, in a
similar fashion to the restoration of the 'IFF_SLAVE' flag.
The issue can be reproduced using the script in [2], with example out
before and after the fix in [3].

[ Upstream commit e8b51a1a15d5a3cce231e0669f6a161dc5bb9b75 ]
The driver does not support PTP on these older chips and it is assuming
that firmware on these older chips will not return the
PORT_MAC_PTP_QCFG_RESP_FLAGS_HWRM_ACCESS flag in __bnxt_hwrm_ptp_qcfg(),
causing the function to abort quietly.
But newer firmware now sets this flag and so __bnxt_hwrm_ptp_qcfg()
will proceed further. Eventually it will fail in bnxt_ptp_init() ->
bnxt_map_ptp_regs() because there is no code to support the older chips.
The driver will then complain:
"PTP initialization failed.\n"
Fix it so that we abort quietly earlier without going through the
unnecessary steps and alarming the user with the warning log.

[ Upstream commit a80bb8e7233b2ad6ff119646b6e33fb3edcec37b ]
There is a use-after-free scenario that is:
When the NIC is down, user set mac address or vlan tag to VF,
the xxx_set_vf_mac() or xxx_set_vf_vlan() will invoke efx_net_stop()
and efx_net_open(), since netif_running() is false, the port will not
start and keep port_enabled false, but selftest_work is scheduled
in efx_net_open().
If we remove the device before selftest_work run, the efx_stop_port()
will not be called since the NIC is down, and then efx is freed,
we will soon get a UAF in run_timer_softirq() like this:

And this is completely possible, as long as the MTU is large, such

[ Upstream commit f8160d3b35fc94491bb0cb974dbda310ef96c0e2 ]
In polling mode, no stop condition is generated after a timeout. This
causes SCL to remain low and thereby block the bus. If this happens
during a transfer it can cause slaves to misinterpret the subsequent
transfer and return wrong values.
To solve this, pass the ETIMEDOUT error up from ocores_process_polling()
instead of setting STATE_ERROR directly. The caller is adjusted to call
ocores_process_timeout() on error both in polling and in IRQ mode, which
will set STATE_ERROR and generate a stop condition.

During the processing of the bgt, if the sync_erase() return -EBUSY
or some other error code in __erase_worker(),schedule_erase() called

Fix this by changing input parameter @nested of the schedule_erase() to
'true' to avoid recursively acquiring the down_read(&ubi->work_sem).
Also, fix the incorrect comment about @nested parameter of the
schedule_erase() because when down_write(ubi->work_sem) is held, the
@nested is also need be true.

commit 1e020e1b96afdecd20680b5b5be2a6ffc3d27628 upstream.

ubi0 error: ubi_attach_mtd_dev [ubi]: VID header offset 2048 too large.
UBI error: cannot attach mtd0

Rework original solution, the key point is making sure
'vid_hdr_shift + UBI_VID_HDR_SIZE < ubi->vid_hdr_alsize',
so we should check vid_hdr_shift rather not vid_hdr_offset.
Then, ubi still support (sub)page aligined VID header offset.

In ses_intf_add, components count could be 0, and kcalloc 0 size scomp,
but not saved in edev->component[i].scratch
In this situation, edev->component[0].scratch is an invalid pointer,
when kfree it in ses_intf_remove_enclosure, a crash like above would happen
The call trace also could be other random cases when kfree cannot catch
the invalid pointer
We should not use edev->component[] array when the components count is 0
We also need check index when use edev->component[] array in
ses_enclosure_data_process

commit 813c2dd78618f108fdcf9cd726ea90f081ee2881 upstream.
sfp->i2c_block_size is initialized at SFP module insertion in
sfp_sm_mod_probe(). Because of that, if SFP module was never inserted
since boot, sfp_read() call will lead to zero-length I2C read attempt,
and not all I2C controllers are happy with zero-length reads.
One way to issue sfp_read() on empty SFP cage is to execute ethtool -m.
If SFP module was never plugged since boot, there will be a zero-length
I2C read attempt.
# ethtool -m xge0
i2c i2c-3: adapter quirk: no zero length (addr 0x0050, size 0, read)
Cannot get Module EEPROM data: Operation not supported
If SFP module was plugged then removed at least once,
sfp->i2c_block_size will be initialized and ethtool -m will fail with
different exit code and without I2C error
# ethtool -m xge0
Cannot get Module EEPROM data: Remote I/O error
Fix this by initializing sfp->i2_block_size at struct sfp allocation
stage so no wild sfp_read() could issue zero-length I2C read.

commit 38518593ec55e897abda4b4be77b2ec8ec4447d1 upstream.
During warm reset device->fw_client is set to NULL. If a bus driver is
registered after this NULL setting and before new firmware clients are
enumerated by ISHTP, kernel panic will result in the function
ishtp_cl_bus_match(). This is because of reference to
device->fw_client->props.protocol_name.
ISH firmware after getting successfully loaded, sends a warm reset
notification to remove all clients from the bus and sets
device->fw_client to NULL. Until kernel v5.15, all enabled ISHTP kernel
module drivers were loaded right after any of the first ISHTP device was
registered, regardless of whether it was a matched or an unmatched
device. This resulted in all drivers getting registered much before the
warm reset notification from ISH.
Starting kernel v5.16, this issue got exposed after the change was
introduced to load only bus drivers for the respective matching devices.
In this scenario, cros_ec_ishtp device and cros_ec_ishtp driver are
registered after the warm reset device fw_client NULL setting.
cros_ec_ishtp driver_register() triggers the callback to
ishtp_cl_bus_match() to match ISHTP driver to the device and causes kernel
panic in guid_equal() when dereferencing fw_client NULL pointer to get
protocol_name.

[ Upstream commit 033c56474acf567a450f8bafca50e0b610f2b716 ]
[Why]
For engines not supporting soft reset, i.e. VCN, there will be a failed
ib test before mode 1 reset during asic reset. The fences in this case
are never signaled and next time when we try to free the sa_bo, kernel
will hang.
[How]
During pre_asic_reset, driver will clear job fences and afterwards the
fences' refcount will be reduced to 1. For drm_sched_jobs it will be
released in job_free_cb, and for non-sched jobs like ib_test, it's meant
to be released in sa_bo_free but only when the fences are signaled. So
we have to force signal the non_sched bad job's fence during
pre_asic_reset or the clear is not complete.

[ Upstream commit 5ed213dd64681f84a01ceaa82fb336cf7d59ddcf ]
Another Lenovo convertable which reports a landscape resolution of
1920x1200 with a pitch of (1920 * 4) bytes, while the actual framebuffer
has a resolution of 1200x1920 with a pitch of (1200 * 4) bytes.

[ Upstream commit cc9812a3096d1986caca9a23bee99effc45c08df ]
After issuing all the messages we can disable the TX_EMPTY interrupts
to avoid handling redundant interrupts. For doing a sinlge bus
detection (i2cdetect -y -r 0) we can reduce ~97% interrupts (before
~12000 after ~400).

[ Upstream commit e8b74453555872851bdd7ea43a7c0ec39659834f ]
For quite some time we were chasing a bug which looked like a sudden
permanent failure of networking and mmc on some of our devices.
The bug was very sensitive to any software changes and even more to
any kernel debug options.
Finally we got a setup where the problem was reproducible with
CONFIG_DMA_API_DEBUG=y and it revealed the issue with the rx dma:

Lars was fast to find an explanation: according to the datasheet
bit 2 of the rx buffer descriptor entry has a different meaning in the
extended mode:
Address [2] of beginning of buffer, or
in extended buffer descriptor mode (DMA configuration register [28] = 1),
indicates a valid timestamp in the buffer descriptor entry.
The macb driver didn't mask this bit while getting an address and it
eventually caused a memory corruption and a dma failure.
The problem is resolved by explicitly clearing the problematic bit
if hw timestamping is used.
