6 years agocarl9170 firmware: fix max beacon length
Christian Lamparter [Sat, 15 Dec 2012 21:19:22 +0000 (22:19 +0100)]
carl9170 firmware: fix max beacon length

According to AR9170's data sheet, the
beacon length register only cares about
bits 8:0. So the max length [with 4
reserved bytes for the FCS] is at 511.

Note:

Because the beacon has to be stored in the
DMA memory region, we have to be careful
so we don't waste precious memory due to
alignment and padding. Therefore I decided
to reduce the max beacon length even more
down to 480 bytes. [This saves one 320 byte
DMA block from becoming unused padding, when
the default 2 vif configuration is selected].

when mac80211 tries to recover it sends out BARs which

mac80211: Implement mesh synchronization framework

This patch adds MBSS extensible synchronization framework (Sec.
13.13.2 of IEEE Std. 802.11-2012).

The framework is implemented via an ops table which defines the
following functions:

    rx_bcn_presp() - this is called every time a mesh beacon is
received.
    adjust_tbtt() - this is called immediately before a beacon is about
to be transmitted.

The default neighbor offset synchronization defined in the standard is
implemented.  We also provide template functions for vendor specific
methods.

When neighbor offset synchronization is active (which is the default)
mesh neighbors in the same MBSS will track timing offsets to each other
and compensate clock drift.

In our tests we observed that this mesh synchronization implementation
successfully corrected drifts between stations of ~2PPM while
introducing a jitter of ~20us.

It is also possible to test this framework on mac80211_hwsim simulated
phys to see how it behaves under different topologies, over poor links,
etc.

will not cause the choice to be considered as NEW, and thus not be
asked. The cause of this behavior is that choice's novelty are computed
statically right after the saved configuration has been read. At this
point, the new dependency's value is still unknown and asserted to be
`no'. Moreover, no update to this decision is made afterward.

Correct this by dynamically evaluating a choice's novelty, and removing the
static evaluation.

kbuild: Fix compiler warning with assertion when calling 'fwrite'

Reinhard Tartler discovered a corner case of calling xfwrite() where the
length of the string is zero.

Arnaud Lacombe suggested to use assertion for the corner case, as
fwrite(3) is currently used:

 1) in comment printers. Empty comment are not allowed.
 2) in a callback passed to expr_print(), where the string printed is
    either NULL OR non-empty.
 3) in the lexer, auto-generated, and unused.

I feel using assertion is a good solution:

 1) It cleanly takes care of the above-mentioned corner case.
 2) It can be easily disabled by defining NDEBUG.
 3) It asserts xfwrite() is simply a wrapper for fwrite().
