The driver for Cisco Aironet 4500 and 4800 series cards (airo.c),
implements AIROOLDIOCTL/SIOCDEVPRIVATE in airo_ioctl().
The ioctl handler copies an aironet_ioctl struct from userspace, which
includes a command. Some of the commands are handled in readrids(),
where the user controlled command is converted into a driver-internal
value called "ridcode".
There are two command values, AIROGWEPKTMP and AIROGWEPKNV, which
correspond to ridcode values of RID_WEP_TEMP and RID_WEP_PERM
respectively. These commands both have checks that the user has
CAP_NET_ADMIN, with the comment that "Only super-user can read WEP
keys", otherwise they return -EPERM.
However there is another command value, AIRORRID, that lets the user
specify the ridcode value directly, with no other checks. This means
the user can bypass the CAP_NET_ADMIN check on AIROGWEPKTMP and
AIROGWEPKNV.
Fix it by moving the CAP_NET_ADMIN check out of the command handling
and instead do it later based on the ridcode. That way regardless of
whether the ridcode is set via AIROGWEPKTMP or AIROGWEPKNV, or passed
in using AIRORID, we always do the CAP_NET_ADMIN check.

The driver for Cisco Aironet 4500 and 4800 series cards (airo.c),
implements AIROOLDIOCTL/SIOCDEVPRIVATE in airo_ioctl().
The ioctl handler copies an aironet_ioctl struct from userspace, which
includes a command and a length. Some of the commands are handled in
readrids(), which kmalloc()'s a buffer of RIDSIZE (2048) bytes.
That buffer is then passed to PC4500_readrid(), which has two cases.
The else case does some setup and then reads up to RIDSIZE bytes from
the hardware into the kmalloc()'ed buffer.
Here len == RIDSIZE, pBuf is the kmalloc()'ed buffer:
// read the rid length field
bap_read(ai, pBuf, 2, BAP1);
// length for remaining part of rid
len = min(len, (int)le16_to_cpu(*(__le16*)pBuf)) - 2;
...
// read remainder of the rid
rc = bap_read(ai, ((__le16*)pBuf)+1, len, BAP1);
PC4500_readrid() then returns to readrids() which does:
len = comp->len;
if (copy_to_user(comp->data, iobuf, min(len, (int)RIDSIZE))) {
Where comp->len is the user controlled length field.
So if the "rid length field" returned by the hardware is < 2048, and
the user requests 2048 bytes in comp->len, we will leak the previous
contents of the kmalloc()'ed buffer to userspace.
Fix it by kzalloc()'ing the buffer.

Commit 323ebb61e3 ("net: use listified RX for handling GRO_NORMAL
skbs") introduces batching of GRO_NORMAL packets in napi_frags_finish,
and commit 6570bc79c0 ("net: core: use listified Rx for GRO_NORMAL in
napi_gro_receive()") adds the same to napi_skb_finish. However,
dev_gro_receive (that is called just before napi_{frags,skb}_finish) can
also pass skbs to the networking stack: e.g., when the GRO session is
flushed, napi_gro_complete is called, which passes pp directly to
netif_receive_skb_internal, skipping napi->rx_list. It means that the
packet stored in pp will be handled by the stack earlier than the
packets that arrived before, but are still waiting in napi->rx_list. It
leads to TCP reorderings that can be observed in the TCPOFOQueue counter
in netstat.
This commit fixes the reordering issue by making napi_gro_complete also
use napi->rx_list, so that all packets going through GRO will keep their
order. In order to keep napi_gro_flush working properly, gro_normal_list
calls are moved after the flush to clear napi->rx_list.
iwlwifi calls napi_gro_flush directly and does the same thing that is
done by gro_normal_list, so the same change is applied there:
napi_gro_flush is moved to be before the flush of napi->rx_list.
A few other drivers also use napi_gro_flush (brocade/bna/bnad.c,
cortina/gemini.c, hisilicon/hns3/hns3_enet.c). The first two also use
napi_complete_done afterwards, which performs the gro_normal_list flush,
so they are fine. The latter calls napi_gro_receive right after
napi_gro_flush, so it can end up with non-empty napi->rx_list anyway.

Since v5.4-rc1 was released, iwlwifi started throwing errors when scan
commands were sent to the firmware with certain devices (depending on
the OTP burned in the device, which contains the list of available
channels). For instance:
iwlwifi 0000:00:14.3: FW error in SYNC CMD SCAN_CFG_CMD
This bug was reported in the ArchLinux bug tracker:
https://bugs.archlinux.org/task/64703
And also in a specific case in bugzilla, when the lar_disabled option
was set: https://bugzilla.kernel.org/show_bug.cgi?id=205193
Revert the commit that introduced this error, by using the number of
channels from the OTP instead of the number of channels that is

After more investigation on the hardware side, it appears that the
hardware bug regarding 2^32 boundary reaching/crossing also affects
other uses of the DMA engine, in particular the ones triggered by
the context-info (image loader) mechanism.
It also turns out that the bug only affects devices with gen2 TX
hardware engine, so we don't need to change context info for gen3.
The TX path workarounds are simpler to still keep for both though.
Add the workaround to that code as well; this is a lot simpler as
we have just a single way to allocate DMA memory there.
I made the algorithm recursive (with a small limit) since it's
actually (almost) impossible to hit this today - dma_alloc_coherent
is currently documented to always return 32-bit addressable memory
regardless of the DMA mask for it, and so we could only get REALLY
unlucky to get the very last page in that area.

If we have offloaded rate scaling, which is always true for those
devices supporting HE, then report the TX rate directly from the
data the firmware gives us, instead of only passing it to mac80211
on frame status only and for it to track it.
First of all, this makes us always report the last good rate that
the rate scaling algorithm picked, which is better than reporting
the last rate for any frame since management frames etc. are sent
with very low rates and could interfere.
Additionally, this allows us to properly report HE rates, though
in case there's a lot of trigger-based traffic, we don't get any
choice in the rates and don't report that properly right now.

As noted in the previous commit, due to the way we allocate the
dev_cmd headers with 324 byte size, and 4/8 byte alignment, the
part we use of them (bytes 20..40-68) could still cross a page
and thus 2^32 boundary.
Address this by using alignment to ensure that the allocation
cannot cross a page boundary, on hardware that's affected. To
make that not cause more memory consumption, reduce the size of
the allocations to the necessary size - we go from 324 bytes in
each allocation to 60/68 on gen2 depending on family, and ~120
or so on gen1 (so on gen1 it's a pure reduction in size, since
we don't need alignment there).
To avoid size and clearing issues, add a new structure that's
just the header, and use kmem_cache_zalloc().

There's a hardware bug in the flow handler (DMA engine), if the
address + len of some TB wraps around a 2^32 boundary, the carry
bit is then carried over into the next TB.
Work around this by copying the data to a new page when we find
this situation, and then copy it in a way that we cannot hit the
very end of the page.
To be able to free the new page again later we need to chain it
to the TSO page, use the last pointer there to make sure we can
never use the page fully for DMA, and thus cannot cause the same
overflow situation on this page.
This leaves a few potential places (where we didn't observe the
problem) unaddressed:
* The second TB could reach or cross the end of a page (and thus
2^32) due to the way we allocate the dev_cmd for the header
* For host commands, a similar thing could happen since they're
just kmalloc().
We'll address these in further commits.

Instead of just having an airtime flag in debugfs, turn AQL into a proper
NL80211_EXT_FEATURE, so drivers can turn it on when they are ready, and so
we also expose the presence of the feature to userspace.
This also has the effect of flipping the default, so drivers have to opt in
to using AQL instead of getting it by default with TXQs. To keep
functionality the same as pre-patch, we set this feature for ath10k (which
is where it is needed the most).
While we're at it, split out the debugfs interface so AQL gets its own
per-station debugfs file instead of using the 'airtime' file.
[Johannes:]
This effectively disables AQL for iwlwifi, where it fixes a number of
issues:
* TSO in iwlwifi is causing underflows and associated warnings in AQL
* HE (802.11ax) rates aren't reported properly so at HE rates, AQL could
never have a valid estimate (it'd use 6 Mbps instead of up to 2400!)

We need to reset the NIC after setting the bits to enable power
gating and that cannot be done too late in the flow otherwise it
cleans other registers and things that were already configured,
causing initialization to fail.
In order to fix this, move the function to the common code in trans.c
so it can be called directly from there at an earlier point, just
after the reset we already do during initialization.

Commit 6570bc79c0 ("net: core: use listified Rx for GRO_NORMAL in
napi_gro_receive()") has applied batched GRO_NORMAL packets processing
to all napi_gro_receive() users, including mac80211-based drivers.
However, this change has led to a regression in iwlwifi driver [1][2] as
it is required for NAPI users to call napi_complete_done() or
napi_complete() and the end of every polling iteration, whilst iwlwifi
doesn't use NAPI scheduling at all and just calls napi_gro_flush().
In that particular case, packets which have not been already flushed
from napi->rx_list stall in it until at least next Rx cycle.
Fix this by adding a manual flushing of the list to iwlwifi driver right
before napi_gro_flush() call to mimic napi_complete() logics.
I prefer to open-code gro_normal_list() rather than exporting it for 2
reasons:
* to prevent from using it and napi_gro_flush() in any new drivers,
as it is the *really* bad way to use NAPI that should be avoided;
* to keep gro_normal_list() static and don't lose any CC optimizations.
I also don't add the "Fixes:" tag as the mentioned commit was only a
trigger that only exposed an improper usage of NAPI in this particular
driver.

Rework event_create_dir() to use an array of static data instead of
function pointers where possible.
The problem is that it would call the function pointer on module load
before parse_args(), possibly even before jump_labels were initialized.
Luckily the generated functions don't use jump_labels but it still seems
fragile. It also gets in the way of changing when we make the module map
executable.
The generated function are basically calling trace_define_field() with a
bunch of static arguments. So instead of a function, capture these
arguments in a static array, avoiding the function call.
Now there are a number of cases where the fields are dynamic (syscall
arguments, kprobes and uprobes), in which case a static array does not
work, for these we preserve the function call. Luckily all these cases
are not related to modules and so we can retain the function call for
them.
Also fix up all broken tracepoint definitions that now generate a
compile error.
