Bjoern A. Zeeb aff56b4f0b net80211: fix a race between ieee80211_sta_join and scan entries
We were seeing panics during ieee80211_sta_join() which seemed that
the ni->ni_chan was not valid anymore, which was true.
We also saw errors indicating data put into ni_ies became inalid.

The problem was that the ieee80211_scan_entry passed into
ieee80211_sta_join() (in the observed case from setmlme_assoc_sta())
became invalid during ieee80211_alloc_node().
As a result for the ni_chan case the the rateset and len in rates[1]
became invalid.  Similarly for the IEs.

Make a (deep)copy of the scan entry in setmlme_assoc_sta() and return
the copy as once we leave ieee80211_scan_iterate() we can no longer
rely on the scan entry to be valid.

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
