[ Upstream commit 3c92792da8506a295afb6d032b4476e46f979725 ]
As lockdep properly warns, we should not be locking i_rwsem while having
transactions started as the proper lock ordering used by all directory
handling operations is i_rwsem -> transaction start. Fix the lock
ordering by moving the locking of the directory earlier in
ext4_rename().

We're currently using stop_machine() to update ftrace & kprobes, which
means that the thread that takes text_mutex during may not be the same
as the thread that eventually patches the code. This isn't actually a
race because the lock is still held (preventing any other concurrent
accesses) and there is only one thread running during stop_machine(),
but it does trigger a lockdep failure.
This patch just elides the lockdep check during stop_machine.

Let's revert commit 12724ba38992 ("erofs: fix kvcalloc() misuse with
__GFP_NOFAIL") since kvmalloc() already supports __GFP_NOFAIL in commit
a421ef303008 ("mm: allow !GFP_KERNEL allocations for kvmalloc"). So
the original fix was wrong.
Actually there was some issue as [1] discussed, so before that mm fix
is landed, the warn could still happen but applying this commit first
will cause less.

[ Upstream commit c8b8a3c601f2cfad25ab5ce5b04df700048aef6e ]
The MT7530 switch from the MT7621 SoC has 2 ports which can be set up as
internal: port 5 and 6. Arınç reports that the GMAC1 attached to port 5
receives corrupted frames, unless port 6 (attached to GMAC0) has been
brought up by the driver. This is true regardless of whether port 5 is
used as a user port or as a CPU port (carrying DSA tags).
Offline debugging (blind for me) which began in the linked thread showed
experimentally that the configuration done by the driver for port 6
contains a step which is needed by port 5 as well - the write to
CORE_GSWPLL_GRP2 (note that I've no idea as to what it does, apart from
the comment "Set core clock into 500Mhz"). Prints put by Arınç show that
the reset value of CORE_GSWPLL_GRP2 is RG_GSWPLL_POSDIV_500M(1) |
RG_GSWPLL_FBKDIV_500M(40) (0x128), both on the MCM MT7530 from the
MT7621 SoC, as well as on the standalone MT7530 from MT7623NI Bananapi
BPI-R2. Apparently, port 5 on the standalone MT7530 can work under both
values of the register, while on the MT7621 SoC it cannot.
The call path that triggers the register write is:
mt753x_phylink_mac_config() for port 6
-> mt753x_pad_setup()
-> mt7530_pad_clk_setup()
so this fully explains the behavior noticed by Arınç, that bringing port
6 up is necessary.
The simplest fix for the problem is to extract the register writes which
are needed for both port 5 and 6 into a common mt7530_pll_setup()
function, which is called at mt7530_setup() time, immediately after
switch reset. We can argue that this mirrors the code layout introduced
in mt7531_setup() by commit 42bc4fafe359 ("net: mt7531: only do PLL once
after the reset"), in that the PLL setup has the exact same positioning,
and further work to consolidate the separate setup() functions is not
hindered.
Testing confirms that:
- the slight reordering of writes to MT7530_P6ECR and to
CORE_GSWPLL_GRP1 / CORE_GSWPLL_GRP2 introduced by this change does not
appear to cause problems for the operation of port 6 on MT7621 and on
MT7623 (where port 5 also always worked)
- packets sent through port 5 are not corrupted anymore, regardless of
whether port 6 is enabled by phylink or not (or even present in the
device tree)
My algorithm for determining the Fixes: tag is as follows. Testing shows
that some logic from mt7530_pad_clk_setup() is needed even for port 5.
Prior to commit ca366d6c889b ("net: dsa: mt7530: Convert to PHYLINK
API"), a call did exist for all phy_is_pseudo_fixed_link() ports - so
port 5 included. That commit replaced it with a temporary "Port 5 is not
supported!" comment, and the following commit 38f790a80560 ("net: dsa:
mt7530: Add support for port 5") replaced that comment with a
configuration procedure in mt7530_setup_port5() which was insufficient
for port 5 to work. I'm laying the blame on the patch that claimed
support for port 5, although one would have also needed the change from
commit c3b8e07909db ("net: dsa: mt7530: setup core clock even in TRGMII
mode") for the write to be performed completely independently from port
6's configuration.
Thanks go to Arınç for describing the problem, for debugging and for
testing.

When the sd driver revalidates host-managed SMR disks, it calls
disk_set_zoned() which changes the zone_write_granularity attribute value
to the logical block size regardless of the device type. After that, the sd
driver overwrites the value in sd_zbc_read_zone() with the physical block
size, since ZBC/ZAC requires this for host-managed disks. Between the calls
to disk_set_zoned() and sd_zbc_read_zone(), there exists a window where the
attribute shows the logical block size as the zone_write_granularity value,
which is wrong for host-managed disks. The duration of the window is from
20ms to 200ms, depending on report zone command execution time.
To avoid the wrong zone_write_granularity value between disk_set_zoned()
and sd_zbc_read_zone(), modify the value not in sd_zbc_read_zone() but
just after disk_set_zoned() call.

[ Upstream commit 9b459804ff9973e173fabafba2a1319f771e85fa ]
btf_datasec_resolve contains a bug that causes the following BTF
to fail loading:
[1] DATASEC a size=2 vlen=2
type_id=4 offset=0 size=1
type_id=7 offset=1 size=1
[2] INT (anon) size=1 bits_offset=0 nr_bits=8 encoding=(none)
[3] PTR (anon) type_id=2
[4] VAR a type_id=3 linkage=0
[5] INT (anon) size=1 bits_offset=0 nr_bits=8 encoding=(none)
[6] TYPEDEF td type_id=5
[7] VAR b type_id=6 linkage=0
This error message is printed during btf_check_all_types:
[1] DATASEC a size=2 vlen=2
type_id=7 offset=1 size=1 Invalid type
By tracing btf_*_resolve we can pinpoint the problem:
btf_datasec_resolve(depth: 1, type_id: 1, mode: RESOLVE_TBD) = 0
btf_var_resolve(depth: 2, type_id: 4, mode: RESOLVE_TBD) = 0
btf_ptr_resolve(depth: 3, type_id: 3, mode: RESOLVE_PTR) = 0
btf_var_resolve(depth: 2, type_id: 4, mode: RESOLVE_PTR) = 0
btf_datasec_resolve(depth: 1, type_id: 1, mode: RESOLVE_PTR) = -22
The last invocation of btf_datasec_resolve should invoke btf_var_resolve
by means of env_stack_push, instead it returns EINVAL. The reason is that
env_stack_push is never executed for the second VAR.
if (!env_type_is_resolve_sink(env, var_type) &&
!env_type_is_resolved(env, var_type_id)) {
env_stack_set_next_member(env, i + 1);
return env_stack_push(env, var_type, var_type_id);
}
env_type_is_resolve_sink() changes its behaviour based on resolve_mode.
For RESOLVE_PTR, we can simplify the if condition to the following:
(btf_type_is_modifier() || btf_type_is_ptr) && !env_type_is_resolved()
Since we're dealing with a VAR the clause evaluates to false. This is
not sufficient to trigger the bug however. The log output and EINVAL
are only generated if btf_type_id_size() fails.
if (!btf_type_id_size(btf, &type_id, &type_size)) {
btf_verifier_log_vsi(env, v->t, vsi, "Invalid type");
return -EINVAL;
}
Most types are sized, so for example a VAR referring to an INT is not a
problem. The bug is only triggered if a VAR points at a modifier. Since
we skipped btf_var_resolve that modifier was also never resolved, which
means that btf_resolved_type_id returns 0 aka VOID for the modifier.
This in turn causes btf_type_id_size to return NULL, triggering EINVAL.
To summarise, the following conditions are necessary:
- VAR pointing at PTR, STRUCT, UNION or ARRAY
- Followed by a VAR pointing at TYPEDEF, VOLATILE, CONST, RESTRICT or
TYPE_TAG
The fix is to reset resolve_mode to RESOLVE_TBD before attempting to
resolve a VAR from a DATASEC.

[ Upstream commit 6c20822fada1b8adb77fa450d03a0d449686a4a9 ]
&xdp_buff and &xdp_frame are bound in a way that
xdp_buff->data_hard_start == xdp_frame
It's always the case and e.g. xdp_convert_buff_to_frame() relies on
this.
IOW, the following:
for (u32 i = 0; i < 0xdead; i++) {
xdpf = xdp_convert_buff_to_frame(&xdp);
xdp_convert_frame_to_buff(xdpf, &xdp);
}
shouldn't ever modify @xdpf's contents or the pointer itself.
However, "live packet" code wrongly treats &xdp_frame as part of its
context placed *before* the data_hard_start. With such flow,
data_hard_start is sizeof(*xdpf) off to the right and no longer points
to the XDP frame.
Instead of replacing `sizeof(ctx)` with `offsetof(ctx, xdpf)` in several
places and praying that there are no more miscalcs left somewhere in the
code, unionize ::frm with ::data in a flex array, so that both starts
pointing to the actual data_hard_start and the XDP frame actually starts
being a part of it, i.e. a part of the headroom, not the context.
A nice side effect is that the maximum frame size for this mode gets
increased by 40 bytes, as xdp_buff::frame_sz includes everything from
data_hard_start (-> includes xdpf already) to the end of XDP/skb shared
info.
Also update %MAX_PKT_SIZE accordingly in the selftests code. Leave it
hardcoded for 64 bit && 4k pages, it can be made more flexible later on.
Minor: align `&head->data` with how `head->frm` is assigned for
consistency.
Minor #2: rename 'frm' to 'frame' in &xdp_page_head while at it for
clarity.
(was found while testing XDP traffic generator on ice, which calls
xdp_convert_frame_to_buff() for each XDP frame)

At btrfs_drop_extent_map_range() we are clearing the EXTENT_FLAG_LOGGING
bit on a 'flags' variable that was not initialized. This makes static
checkers complain about it, so initialize the 'flags' variable before
clearing the bit.
In practice this has no consequences, because EXTENT_FLAG_LOGGING should
not be set when btrfs_drop_extent_map_range() is called, as an fsync locks
the inode in exclusive mode, locks the inode's mmap semaphore in exclusive
mode too and it always flushes all delalloc.
Also add a comment about why we clear EXTENT_FLAG_LOGGING on a copy of the
flags of the split extent map.

Functions that are called from either xtables or nftables must assume

When unregistering a net device, unregister_netdevice_many_notify()
sets the device's reg_state to NETREG_UNREGISTERING, calls notifiers

Later on, devices in the todo list are processed by netdev_run_todo().
netdev_run_todo() waits devices' reference count become 1 while

When cfusbl_device_notify() is called with NETDEV_UNREGISTER multiple

Processing NETDEV_UNREGISTER multiple times also causes inbalance of

<quote>
There is a noticeable tcp performance regression (loopback or cross-netns),
seen with iperf3 -Z (sendfile mode) when generic retpolines are needed.
With SK_RECLAIM_THRESHOLD checks gone number of calls to enter/leave
memory pressure happen much more often. For TCP indirect calls are
used.
We can't remove the if-set-return short-circuit check in
tcp_enter_memory_pressure because there are callers other than
sk_enter_memory_pressure. Doing a check in the sk wrapper too
reduces the indirect calls enough to recover some performance.

[ Upstream commit 49c47cc21b5b7a3d8deb18fc57b0aa2ab1286962 ]
ctx->crypto_send.info is not protected by lock_sock in
do_tls_getsockopt_conf(). A race condition between do_tls_getsockopt_conf()
and error paths of do_tls_setsockopt_conf() may lead to a use-after-free
or null-deref.

If the ruleset contains consumed quota, restore them accordingly.
Otherwise, listing after restoration shows never used items.
Restore the user-defined quota and flags too.

[ Upstream commit 2067e7a00aa604b94de31d64f29b8893b1696f26 ]
The test_local_dnat_portonly() function initiates the client-side as
soon as it sets the listening side to the background. This could lead to
a race condition where the server may not be ready to listen. To ensure
that the server-side is up and running before initiating the
client-side, a delay is introduced to the test_local_dnat_portonly()
function.

[ Upstream commit 81563d8548b0478075c720666be348d4199b8591 ]
When the police was removed from the port, then it was trying to
remove the police from the police id and not from the actual
police index.
The police id represents the id of the police and police index
represents the position in HW where the police is situated.
The port police id can be any number while the port police index
is a number based on the port chip port.
Fix this by deleting the police from HW that is situated at the
police index and not police id.

Gaurav reports that TLS Rx is broken with async crypto
accelerators. The commit under fixes missed updating
the retval byte counting logic when updating how records
are stored. Even tho both before and after the change
'decrypted' was updated inside the main loop, it was
completely overwritten when processing the async
completions. Now that the rx_list only holds
non-zero-copy records we need to add, not overwrite.
