wireless: fix nl80211 vendor commands

2019-07-20T19:37:26+00:00

In my previous commit to validate a policy I neglected to
actually add one to the few drivers using vendor commands,
fix that now.

====================
wireless-drivers-next patches for 5.2

Most likely the last patchset of new feature for 5.2, and this time we
have quite a lot of new features. Most obvious being rtw88 from
Realtek which supports RTL8822BE and RTL8822CE 802.11ac devices. We
have also new hardware support for existing drivers and improvements.

There's one conflict in iwlwifi, my example conflict resolution below.

Major changes:

iwlwifi

* bump the 20000-series FW API version

* work on new hardware continues

* RTT confidence indication support for Fine Timing Measurement (FTM)

* an improvement in HE (802.11ax) rate-scaling

* add command version parsing from the fimware TLVs

* add support for a new WoWLAN patterns firmware API

rsi

* add support for rs9116

mwifiex

* add support for SD8987

brcmfmac

* add quirk for ACEPC T8 and T11 mini PCs

rt2x00

* add RT3883 support

qtnfmac

* fix debugfs interface to support multiple cards

rtw88

* new driver

mt76

* share more code across drivers

* add support for MT7615 chipset

* rework DMA API

* tx/rx performance optimizations

* use NAPI for tx cleanup on mt76x02

* AP mode support for USB devices

* USB stability fixes

* tx power handling fixes for 76x2

* endian fixes

Conflicts:

There's a trivial conflict in
drivers/net/wireless/intel/iwlwifi/fw/file.h, just leave
IWL_UCODE_TLV_FW_FSEQ_VERSION to the file. 'git diff' output should be
just empty:

netlink: make validation more configurable for future strictness

2019-04-27T21:07:21+00:00

We currently have two levels of strict validation:

 1) liberal (default)
     - undefined (type >= max) & NLA_UNSPEC attributes accepted
     - attribute length >= expected accepted
     - garbage at end of message accepted
 2) strict (opt-in)
     - NLA_UNSPEC attributes accepted
     - attribute length >= expected accepted

Split out parsing strictness into four different options:
 * TRAILING     - check that there's no trailing data after parsing
                  attributes (in message or nested)
 * MAXTYPE      - reject attrs > max known type
 * UNSPEC       - reject attributes with NLA_UNSPEC policy entries
 * STRICT_ATTRS - strictly validate attribute size

The default for future things should be *everything*.
The current *_strict() is a combination of TRAILING and MAXTYPE,
and is renamed to _deprecated_strict().
The current regular parsing has none of this, and is renamed to
*_parse_deprecated().

Additionally it allows us to selectively set one of the new flags
even on old policies. Notably, the UNSPEC flag could be useful in
this case, since it can be arranged (by filling in the policy) to
not be an incompatible userspace ABI change, but would then going
forward prevent forgetting attribute entries. Similar can apply
to the POLICY flag.

We end up with the following renames:
 * nla_parse           -> nla_parse_deprecated
 * nla_parse_strict    -> nla_parse_deprecated_strict
 * nlmsg_parse         -> nlmsg_parse_deprecated
 * nlmsg_parse_strict  -> nlmsg_parse_deprecated_strict
 * nla_parse_nested    -> nla_parse_nested_deprecated
 * nla_validate_nested -> nla_validate_nested_deprecated

Using spatch, of course:

    +nlmsg_validate_deprecated(NLH, HDRLEN, MAX, POL, EXT)

For this patch, don't actually add the strict, non-renamed versions
yet so that it breaks compile if I get it wrong.

Also, while at it, make nla_validate and nla_parse go down to a
common __nla_validate_parse() function to avoid code duplication.

Ultimately, this allows us to have very strict validation for every
new caller of nla_parse()/nlmsg_parse() etc as re-introduced in the
next patch, while existing things will continue to work as is.

In effect then, this adds fully strict validation for any new command.
