memory-mapped devices that are normally PCIe drives. Devices can then use
the existing pci_get_class, etc. accessors to query this data.

The ivar values are different enough from the existing ACPI and ISA values

7aebd3e55d [net80211] sigh, course I would miss a commit from the 11ac prep commit. 2016-12-16 04:44:14 +00:00
Adrian Chadd
fdbc9e6e82 [net80211] start laying down the foundation for 11ac support.
This is a work in progress and some of this stuff may change;
but hopefully I'm laying down enough stuff and space in fields
to allow it to grow without another major recompile.

We'll see!

* Add a net80211 PHY type for VHT 2G and VHT 5G.

  Note - yes, VHT is supposed to be for 5GHZ, however some vendors
  (*cough* most of them) support some subset of VHT rate support
  in 2GHz.  No - not 80MHz wide channels, but at least some MCS8-9
  support, maybe some beamforming, and maybe some longer A-MPDU
  aggregates.  I don't want to even think about MU-MIMO on 2GHz.

* Add an ifmedia placeholder type for VHT rates.

* Add channel flags for VHT, VHT20/40U/40D/80/80+80/160
* Add channel macros for the above
* Add ieee80211_channel fields for the VHT information and flags,
  along with some padding (so this struct definitely grows.)
* Add a phy type flag for VHT - 'v'

* Bump the number of channels to a much higher amount - until we get
  something like the linux mac80211 chanctx abstraction (where the
  stack provides a current channel configuration via callbacks,
  versus the driver ever checking ic->ic_curchan or similar) we'll
  have to populate VHT+HT combinations.

Eg, there'll likely be a full set of duplicate VHT20/40 channels to match
HT channels.  There will also be a full set of duplicate VHT80 channels -
note that for VHT80, its assumed you're doing VHT40 as a base, so we
don't need a duplicate of VHT80 + 20MHz only primary channels, only
a duplicate of all the VHT40 combinations.

I don't want to think about VHT80+80 or VHT160 for now - and I won't,
as the current device I'm doing 11ac bringup on (QCA9880) only does
VHT80.

I'll likely revisit the channel configuration and scanning related
stuff after I get VHT20/40 up.

* Add vht flags and the basic MCS rate setup to ieee80211com, ieee80211vap
  and ieee80211_node in preparation for 11ac configuration.
  There is zero code that uses this right now.
* Whilst here, add some more placeholders in case I need to extend
  out things by some uint32_t flag sized fields.  Hopefully I won't!

What I haven't yet done:

* any of the code that uses this
* any of the beamforming related fields
* any of the MU-MIMO fields required for STA/AP operation
* any of the IE fields in beacon frame / probe request/response handling
  and the calculations required for shifting beacon contents around
  when the TIM grows/shrinks

This will require a full rebuild of net80211 related programs -
ifconfig, hostapd, wpa_supplicant.

280dd9fc2e iconv(1): Capsicumify
This takes the usual shortcut of only sandboxing the last input file.
It's a first cut and this program will be easy to adapt to sandbox all
files in the future.

iconv(1) has been changed to only open the conversion descriptor once,
since the input and output encodings are fixed over all inputs.
Instead, the descriptor is simply reset after each use (documented in
iconv(3) API).

We wait until after kvm_nlist() is invoked to cap_enter() because
kldsym() isn't supported in the Capsicum sandbox.

I'm unclear on if (more) non-portable printf extensions will be a

6a1c4d1efc capsicum_helpers: Add LOOKUP flag
Add a helper routine for opening a directory that is restricted to being

I think this will really help basic adaptation of multi-file programs to
Capsicum. Rather than having each program initialize a rights object and
ioctl/fcntl arrays for their root fd for relative opens, consolidate in the
logical place.
