https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=223794 Bug ID: 223794 Summary: ifconfig manual page doesn't match source about list scan and list sta Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: reed@reedmedia.net See sbin/ifconfig/ifieee80211.c and sbin/ifconfig/ifconfig.8 The list_scan() code uses getcaps() and printies(). The list_stations() code uses getcaps() and getflags() and printies(). For example: getcaps has A as CAPINFO_CHNL_AGILITY, E is CAPINFO_ESS, and P is CAPINFO_PRIVACY; and getflags has A as NODE_AUTH, E is NODE_ERP, and P is NODE_PWR_MGT. The manpage has multiple problems. The list scan section has "Depending on the capabilities of the stations the following flags can be included in the output:" But it lists A as Authjorized, E as ERP, P as Powersave, etc. This has the getflags stuff and not capabiltiies. If you want you may consider some content or hints from the following: A -- Channel Agility allows channel switching or frequency hopping. B -- Packet Binary Convolutional Code (PBCC) mode provides error correction to help improve performance. Nevertheless, newer technologies have faster rates. c -- Contention-free (CF) pollable uses Point coordination function (PCF) and is able to participate in its QoS. C -- CF Pollable Request D -- This 802.11g feature provides both direct-sequence spread spectrum (DSSS) and Orthogonal frequency-division multiplexing (OFDM) methods. E -- Extended Service Set (ESS). Infrastructure mode providing an Access Point where devices can communicate with each other. (It may have more than one AP for roaming.) I -- Independent Basic Service Set (IBBS) is an ad-hoc network with no access point. (It can only connect to one station at a time.) P -- Wired Equivalent Privacy (WEP). This is weak security that has been superseded by WPA. R -- Robust Security Network (RSN) encrypts the whole frame. This is WPA2. s -- Short Slot Times reduce retransmission delay after collisions to increase throughput. S -- Short Preambles have reduced packet headers to improve performance. Old devices require long preambles. This is a 802.11g feature. Other problems are in the "list sta" section where it documents flags. S as "Short Preamble" but code is about "Short GI in HT40 enabled". (I think is different.): T as "Transitional Security Network (TSN)" but code is about "AMPDU tx enabled". (I think that is wrong.) (I noticed all this as I originally saw mistakes in pfSense wireless stats page and realized the upstream manual page also had mistakes. I am authoring a very detailed book about pfSense. http://reedmedia.net/books/pfsense/ ) -- You are receiving this mail because: You are the assignee for the bug.
