[PATCH AUTOSEL 5.9 01/15] ARM: sunxi: Add machine match for the Allwinner V3 SoC

[PATCH AUTOSEL 5.9 01/15] ARM: sunxi: Add machine match for the Allwinner V3 SoC

[Sasha Levin]

From: Paul Kocialkowski <contact@paulk.fr>

[ Upstream commit ad2091f893bd5dfe2824f0d6819600d120698e9f ]

The Allwinner V3 SoC shares the same base as the V3s but comes with
extra pins and features available. As a result, it has its dedicated
compatible string (already used in device trees), which is added here.

[PATCH AUTOSEL 5.9 02/15] pNFS/flexfiles: Fix array overflow when flexfiles mirroring is enabled

[Sasha Levin]

From: Trond Myklebust <trond.myklebust@hammerspace.com>

[ Upstream commit 63e2fffa59a9dd91e443b08832656399fd80b7f0 ]

If the flexfiles mirroring is enabled, then the read code expects to be
able to set pgio->pg_mirror_idx to point to the data server that is
being used for this particular read. However it does not change the
pg_mirror_count because we only need to send a single read.

[PATCH AUTOSEL 5.9 05/15] [SECURITY] fix namespaced fscaps when !CONFIG_SECURITY

[Sasha Levin]

From: Serge Hallyn <shallyn@cisco.com>

[ Upstream commit ed9b25d1970a4787ac6a39c2091e63b127ecbfc1 ]

Namespaced file capabilities were introduced in 8db6c34f1dbc .
When userspace reads an xattr for a namespaced capability, a
virtualized representation of it is returned if the caller is
in a user namespace owned by the capability's owning rootid.
The function which performs this virtualization was not hooked
up if CONFIG_SECURITY=n.  Therefore in that case the original
xattr was shown instead of the virtualized one.

To test this using libcap-bin (*1),

$ v=$(mktemp)
$ unshare -Ur setcap cap_sys_admin-eip $v
$ unshare -Ur setcap -v cap_sys_admin-eip $v
/tmp/tmp.lSiIFRvt8Y: OK

"setcap -v" verifies the values instead of setting them, and
will check whether the rootid value is set.  Therefore, with
this bug un-fixed, and with CONFIG_SECURITY=n, setcap -v will
fail:

$ v=$(mktemp)
$ unshare -Ur setcap cap_sys_admin=eip $v
$ unshare -Ur setcap -v cap_sys_admin=eip $v
nsowner[got=1000, want=0],/tmp/tmp.HHDiOOl9fY differs in []

Fix this bug by calling cap_inode_getsecurity() in
security_inode_getsecurity() instead of returning
-EOPNOTSUPP, when CONFIG_SECURITY=n.

*1 - note, if libcap is too old for getcap to have the '-n'
option, then use verify-caps instead.

[PATCH AUTOSEL 5.9 06/15] lwt: Disable BH too in run_lwt_bpf()

[Sasha Levin]

From: Dongdong Wang <wangdongdong.6@bytedance.com>

[ Upstream commit d9054a1ff585ba01029584ab730efc794603d68f ]

The per-cpu bpf_redirect_info is shared among all skb_do_redirect()
and BPF redirect helpers. Callers on RX path are all in BH context,
disabling preemption is not sufficient to prevent BH interruption.

In production, we observed strange packet drops because of the race
condition between LWT xmit and TC ingress, and we verified this issue
is fixed after we disable BH.

Although this bug was technically introduced from the beginning, that
is commit 3a0af8fd61f9 ("bpf: BPF for lightweight tunnel infrastructure"),
at that time call_rcu() had to be call_rcu_bh() to match the RCU context.
So this patch may not work well before RCU flavor consolidation has been
completed around v5.0.

Update the comments above the code too, as call_rcu() is now BH friendly.

[PATCH AUTOSEL 5.9 08/15] drm/amd/display: Prevent bandwidth overflow

From: Chris Park <Chris.Park@amd.com>

[ Upstream commit 80089dd8410f356d5104496d5ab71a66a4f4646b ]

[Why]
At very high pixel clock, bandwidth calculation exceeds 32 bit size
and overflow value. This causes the resulting selection of link rate
to be inaccurate.

[How]
Change order of operation and use fixed point to deal with integer
accuracy. Also address bug found when forcing link rate.

[PATCH AUTOSEL 5.9 11/15] selftests/bpf: Fix array access with signed variable test

[Sasha Levin]

From: Jean-Philippe Brucker <jean-philippe@linaro.org>

[ Upstream commit 77ce220c0549dcc3db8226c61c60e83fc59dfafc ]

The test fails because of a recent fix to the verifier, even though this
program is valid. In details what happens is:

    7: (61) r1 = *(u32 *)(r0 +0)

Load a 32-bit value, with signed bounds [S32_MIN, S32_MAX]. The bounds
of the 64-bit value are [0, U32_MAX]...

    8: (65) if r1 s> 0xffffffff goto pc+1

... therefore this is always true (the operand is sign-extended).

    10: (b4) w2 = 11
    11: (6d) if r2 s> r1 goto pc+1

When true, the 64-bit bounds become [0, 10]. The 32-bit bounds are still
[S32_MIN, 10].

    13: (64) w1 <<= 2

Because this is a 32-bit operation, the verifier propagates the new
32-bit bounds to the 64-bit ones, and the knowledge gained from insn 11
is lost.

    14: (0f) r0 += r1
    15: (7a) *(u64 *)(r0 +0) = 4

Then the verifier considers r0 unbounded here, rejecting the test. To
make the test work, change insn 8 to check the sign of the 32-bit value.

[PATCH AUTOSEL 5.9 13/15] initramfs: fix clang build failure

[Sasha Levin]

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit 55d5b7dd6451b58489ce384282ca5a4a289eb8d5 ]

There is only one function in init/initramfs.c that is in the .text
section, and it is marked __weak.  When building with clang-12 and the
integrated assembler, this leads to a bug with recordmcount:

  ./scripts/recordmcount  "init/initramfs.o"
  Cannot find symbol for section 2: .text.
  init/initramfs.o: failed

I'm not quite sure what exactly goes wrong, but I notice that this
function is only ever called from an __init function, and normally
inlined.  Marking it __init as well is clearly correct and it leads to
recordmcount no longer complaining.
