[PATCH AUTOSEL 5.10 06/51] ath11k: fix crash caused by NULL rx_channel

[Sasha Levin]

From: Carl Huang <cjhuang@codeaurora.org>

[ Upstream commit 3597010630d0aa96f5778901e691c6068bb86318 ]

During connect and disconnect stress test, crashed happened
because ar->rx_channel is NULL. Fix it by checking whether
ar->rx_channel is NULL.

Crash stack is as below:

[PATCH AUTOSEL 5.10 07/51] rtlwifi: rise completion at the last step of firmware callback

[Sasha Levin]

From: Ping-Ke Shih <pkshih@realtek.com>

[ Upstream commit 4dfde294b9792dcf8615b55c58f093d544f472f0 ]

request_firmware_nowait() which schedules another work is used to load
firmware when USB is probing. If USB is unplugged before running the
firmware work, it goes disconnect ops, and then causes use-after-free.
Though we wait for completion of firmware work before freeing the hw,
firmware callback rises completion too early. So I move it to the
last step.

[PATCH AUTOSEL 5.10 08/51] netfilter: ipset: fixes possible oops in mtype_resize

[Sasha Levin]

From: Vasily Averin <vvs@virtuozzo.com>

[ Upstream commit 2b33d6ffa9e38f344418976b06057e2fc2aa9e2a ]

currently mtype_resize() can cause oops

        t = ip_set_alloc(htable_size(htable_bits));
        if (!t) {
                ret = -ENOMEM;
                goto out;
        }
        t->hregion = ip_set_alloc(ahash_sizeof_regions(htable_bits));

Increased htable_bits can force htable_size() to return 0.
In own turn ip_set_alloc(0) returns not 0 but ZERO_SIZE_PTR,
so follwoing access to t->hregion should trigger an OOPS.

[PATCH AUTOSEL 5.10 09/51] ath11k: qmi: try to allocate a big block of DMA memory first

[Sasha Levin]

From: Carl Huang <cjhuang@codeaurora.org>

[ Upstream commit f6f92968e1e5a7a9d211faaebefc26ebe408dad7 ]

Not all firmware versions support allocating DMA memory in smaller blocks so
first try to allocate big block of DMA memory for QMI. If the allocation fails,
let firmware request multiple blocks of DMA memory with smaller size.

This also fixes an unnecessary error message seen during ath11k probe on
QCA6390:

ath11k_pci 0000:06:00.0: Respond mem req failed, result: 1, err: 0
ath11k_pci 0000:06:00.0: qmi failed to respond fw mem req:-22

[PATCH AUTOSEL 5.10 14/51] ethernet: ucc_geth: fix definition and size of ucc_geth_tx_global_pram

[Sasha Levin]

From: Rasmus Villemoes <rasmus.villemoes@prevas.dk>

[ Upstream commit 887078de2a23689e29d6fa1b75d7cbc544c280be ]

Table 8-53 in the QUICC Engine Reference manual shows definitions of
fields up to a size of 192 bytes, not just 128. But in table 8-111,
one does find the text

  Base Address of the Global Transmitter Parameter RAM Page. [...]
  The user needs to allocate 128 bytes for this page. The address must
  be aligned to the page size.

I've checked both rev. 7 (11/2015) and rev. 9 (05/2018) of the manual;
they both have this inconsistency (and the table numbers are the
same).

Adding a bit of debug printing, on my board the struct
ucc_geth_tx_global_pram is allocated at offset 0x880, while
the (opaque) ucc_geth_thread_data_tx gets allocated immediately
afterwards, at 0x900. So whatever the engine writes into the thread
data overlaps with the tail of the global tx pram (and devmem says
that something does get written during a simple ping).

I haven't observed any failure that could be attributed to this, but
it seems to be the kind of thing that would be extremely hard to
debug. So extend the struct definition so that we do allocate 192
bytes.

[PATCH AUTOSEL 5.10 18/51] e1000e: Only run S0ix flows if shutdown succeeded

[Sasha Levin]

From: Mario Limonciello <mario.limonciello@dell.com>

[ Upstream commit 808e0d8832cc81738f3e8df12dff0688352baf50 ]

If the shutdown failed, the part will be thawed and running
S0ix flows will put it into an undefined state.

[PATCH AUTOSEL 5.10 23/51] CDC-NCM: remove "connected" log message

[Sasha Levin]

From: Roland Dreier <roland@kernel.org>

[ Upstream commit 59b4a8fa27f5a895582ada1ae5034af7c94a57b5 ]

The cdc_ncm driver passes network connection notifications up to
usbnet_link_change(), which is the right place for any logging.
Remove the netdev_info() duplicating this from the driver itself.

This stops devices such as my "TRENDnet USB 10/100/1G/2.5G LAN"
(ID 20f4:e02b) adapter from spamming the kernel log with

    cdc_ncm 2-2:2.0 enp0s2u2c2: network connection: connected

messages every 60 msec or so.

[PATCH AUTOSEL 5.10 37/51] selftests: fix the return value for UDP GRO test

[Sasha Levin]

From: Po-Hsu Lin <po-hsu.lin@canonical.com>

[ Upstream commit 3503ee6c0bec5f173d606359e6384a5ef85492fb ]

The udpgro.sh will always return 0 (unless the bpf selftest was not
build first) even if there are some failed sub test-cases.

Therefore the kselftest framework will report this case is OK.

Check and return the exit status of each test to make it easier to
spot real failures.
