Add documentation of the build options WITH_GH_BC and WITHOUT_GH_BC to optionally replace the traditional implementation of bc(1) and dc(1) with the new implementation that has become the default version in -CURRENT. The man-page differs from the one in -CURRENT due to different default values of that build option. Approved by: re (gjb)

MFC r365371: Turn MALLOC_PRODUCTION into a regular src.conf(5) option For historical reasons, defining MALLOC_PRODUCTION in /etc/make.conf has been used to turn off potentially expensive debug checks and statistics gathering in the implementation of malloc(3). It seems more consistent to turn this into a regular src.conf(5) option, e.g. WITH_MALLOC_PRODUCTION / WITHOUT_MALLOC_PRODUCTION. This can then be toggled similar to any other source build option, and turned on or off by default for e.g. stable branches. Reviewed by: imp, #manpages Differential Revision: https://reviews.freebsd.org/D26337 MFC r365373: Follow-up r365371 by removing sentences which indicate the state of the MK_MALLOC_PRODUCTION option on -CURRENT. Also, for the sake of backwards compatibility, support the old way of enabling 'production malloc', e.g. by adding a define in make.conf(5). MF12 r365671: Follow-up r365662 (MFC of r365371 and r365373) by correctly setting WITH_MALLOC_PRODUCTION for stable branches. Also add a note to UPDATING, to inform users about the new setting. Direct commit to stable/{11,12} as this does not apply to head. Noticed by: imp, Ronald Klop MF12 r365672: Follow-up r365662 (MFC of r365371 and r365373) by also removing the header hack from jemalloc_FreeBSD.h, which rendered any make.conf MALLOC_PRODUCTION or src.conf WITH/WITHOUT_MALLOC_PRODUCTION irrelevant.

Merge WiFi net80211, drivers, and management in order to support better 11n and upcoming 11ac. This includes an ath(4) update, some run(4) 11n support, 11n for otus(4), A-MPDU, A-MSDU, A-MPDU+A-MSDU and Fast frames options, scanning fixes, enhanced PRIV checks for jails, restored parent device name printing, improvements for upcoming VHT support, lots of under-the-hood infrastructure improvements, new device ID, debug tools updates, some whitespace changes (to make future MFCs easier). This does not include (most) epoch(9) related changes as too much other infrastructure was not merged for that. Tested on: some ath(4) AP, run(4) STA, and rtwn(4) STA Discussed with: adrian (extremely briefly) Sponsored by: Rubicon Communications, LLC (d/b/a "Netgate") [partially] Approved by: re (gjb) Relnotes: yes

r362420 | imp | 2020-06-19 22:07:44 -0600 (Fri, 19 Jun 2020) | 13 lines Correct 1BSD release date. The Quarter Century of Unix book said that 1BSD was released March 1979. However, the 1BSD tape image that's on Kirk's historical unix collection has an earlier date. It was common practice, at the time, to create a new copy of the tape from the master system when a new tape was to go out, so several different versions of 1BSD, etc were shipped from Berkerely. The date on the 1BSD tape in the Berkeley archives on Kirk's DVD is dated in January 16 1979 on the label, and has dates as late as Jan 29 (there's an UPDATE file that says this includes updates through this date). Note this date as well.
