Similar to the handling of play_deferred in commit 19cfe912
("Bluetooth: btusb: Fix memory leak in play_deferred"), we thought
a patch might be needed here as well.

Currently usb_submit_urb is called directly to submit deferred tx
urbs after unanchor them.

So the usb_giveback_urb_bh would failed to unref it in usb_unanchor_urb
and cause memory leak.

Put those urbs in tx_anchor to avoid the leak, and also fix the error
handling.

The transaction buffer is allocated by using the size of the packet buf,
and subtracting two which seem intended to remove the two tags which are
not present in the target structure. This calculation leads to under
counting memory because of differences between the packet contents and the
target structure. The aid_len field is a u8 in the packet, but a u32 in
the structure, resulting in at least 3 bytes always being under counted.
Further, the aid data is a variable length field in the packet, but fixed
in the structure, so if this field is less than the max, the difference is
added to the under counting.

The last validation check for transaction->params_len is also incorrect
since it employs the same accounting error.

To fix, perform validation checks progressively to safely reach the
next field, to determine the size of both buffers and verify both tags.
Once all validation checks pass, allocate the buffer and copy the data.
This eliminates freeing memory on the error path, as those checks are
moved ahead of memory allocation.

The first validation check for EVT_TRANSACTION has two different checks
tied together with logical AND. One is a check for minimum packet length,
and the other is for a valid aid_tag. If either condition is true (fails),
then an error should be triggered.  The fix is to change && to ||.

net: unexport some symbols that are annotated __init

This patch set fixes odd combinations
of EXPORT_SYMBOL and __init.

Checking this in modpost is a good thing and I really wanted to do it,
but Linus Torvalds imposes a very strict rule, "No new warning".

I'd like the maintainer to kindly pick this up and send a fixes pull request.

Unless I eliminate all the sites of warnings beforehand,
Linus refuses to re-enable the modpost check. [1]

EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.

modpost used to detect it, but it has been broken for a decade.

Recently, I fixed modpost so it started to warn it again, then this
showed up in linux-next builds.

There are two ways to fix it:

  - Remove __init
  - Remove EXPORT_SYMBOL

I chose the latter for this case because the caller (net/ipv6/seg6.c)
and the callee (net/ipv6/seg6_hmac.c) belong to the same module.
It seems an internal function call in ipv6.ko.

There is a limitation in TI DP83867 PHY device where SGMII AN is only
triggered once after the device is booted up. Even after the PHY TPI is
down and up again, SGMII AN is not triggered and hence no new in-band
message from PHY to MAC side SGMII.

This could cause an issue during power up, when PHY is up prior to MAC.
At this condition, once MAC side SGMII is up, MAC side SGMII wouldn`t
receive new in-band message from TI PHY with correct link status, speed
and duplex info.

As suggested by TI, implemented a SW solution here to retrigger SGMII
Auto-Neg whenever there is a link change.

While analyzing yet another syzbot report, I found the following
patch very useful. It allows to better understand what went wrong.

This debug info is only enabled if CONFIG_DEBUG_NET=y,
which is the case for syzbot builds.

I have a board where these two lines are always printed during boot:

   imx-dwmac 30bf0000.ethernet: Cannot register the MDIO bus
   imx-dwmac 30bf0000.ethernet: stmmac_dvr_probe: MDIO bus (id: 1) registration failed

It's perfectly fine, and the device is successfully (and silently, as
far as the console goes) probed later.

Use dev_err_probe() instead, which will demote these messages to debug
level (thus removing the alarming messages from the console) when the
error is -EPROBE_DEFER, and also has the advantage of including the
error code if/when it happens to be something other than -EPROBE_DEFER.

While here, add the missing \n to one of the format strings.
