2011-11-17Complete the HISTORY of all syscalls that exist since Version 1 AT&T UNIX.Ingo Schwarze

2011-11-17Fix HISTORY:Ingo Schwarze
Mention the predecessor exec() in v1, and remove the bogus "appeared in 3BSD", just leave "execve() appeared in v7", because: (1) There is a direct line of inheritance from v7 (Bell, Jan 1979) via 32v (Bell, May 1979) to 3BSD (UCB, Feb 1980), and it goes without saying that children include code from their grandparents. (2) It is impossible that there was parallel development of execve() at Bell and UCB. The only UCB release before v7 was 1BSD (May 1978), and even 2BSD (May 1979) did not include any kernel parts but fully relied on the Bell v6 kernel. When Bell released 32v, the UCB did not even own a VAX, and Bill Joy was still are pure userland hacker. Only after the original UCBVAX arrived at Berkeley, Richard Fateman involved Domenico Ferrari who involved Ozalp Babaoglu who started kernel work at UCB, based on Bell 32v, later involving Bill Joy. (3) Genetic analysis of the source code confirms this. All kernel code involved is in sys1.c. Regarding this file, the first two UCB releases, VAX 3BSD (based on Bell 32v) and PDP-11 2.8BSD (Dec 1981, based on Bell v7) are more similar to their respective Bell parents than to each other. The Berkeley versions are cousins, not siblings: v7 -> 32v: 523 +71 -60 = 534 v7 -> 2.8: 523 +305 -24 = 804 32v -> 3: 534 +169 -110 = 593 3 -> 2.8: 593 +413 -202 = 804 References: http://oreilly.com/catalog/opensources/book/kirkmck.html http://minnie.tuhs.org/cgi-bin/utree.pl?file=32V http://minnie.tuhs.org/cgi-bin/utree.pl?file=V7/usr/sys/sys/sys1.c http://minnie.tuhs.org/cgi-bin/utree.pl?file=32V/usr/src/sys/sys/sys1.c http://minnie.tuhs.org/cgi-bin/utree.pl?file=3BSD/usr/src/sys/sys/sys1.c https://www.mckusick.com/csrg/ - /cdrom1/2.8/usr/kernel/sys/sys/sys1.c facts checked and ok sobrado@, style and formatting ok jmc@
2011-11-16Fix mbstowcs return value documentation. New text based on mbsrtowcs page.Stefan Sperling
ok jmc
2011-11-15Add a "device number" component in sndio(7) device names, allowing aAlexandre Ratchov
single aucat instance to handle all audio and MIDI services. Since this partially breaks compatibility, this is a opportunitiy to fix few other design mistakes (eg ':' being used by inet6, type name vs api name confusion, etc..). This leads to the following names: type[@hostname][,unit]/devnum[.option] The device number is the minor device number for direct hardware access (ie the 'N' in /dev/audioN). For aucat, this is the occurence number of the -f (or -M) option. There's a compatibility hook to keep old names working if only one aucat server is running.

2011-10-27Allow segments to be used even after they were marked for deletion withRobert Nagy
the IPC_RMID flag. This is permitted as an extension beyond the standards and this is similar to what other operating systems like linux do. Because compat_linux(8) was emulating this already, remove that code since now this is the default. input from oga@, guenther@, jmc@, deraadt@ ok deraadt@

2011-10-19Remove some blatant lies. Provide a variant 1 archs with a defaultPhilip Guenthe
value for THREAD_ERRNOPTR_OFFSET (can't be used from ASM or ld.so, but it lets things compile as we fill things in)

2011-10-17Remove midicat since aucat can now be used instead of midicatAlexandre Ratchov
with almost the same syntax (roughly an extra -M option). Thru boxes are created with aucat, and corresponding MIDI port names have the "aucat" prefix instead of "midithru". The old device name will still work some time for backward compatibility. ok deraadt
2011-10-17Use __tfork, __get_tcb, and __set_tcb to have a real TCB and per-threadPhilip Guenthe
errno. The ASM bits for _cerror are sketchy or missing for some archs but that can be corrected in-tree.

handling to fix up the alignment of 64bit arguments so that they do the same dance where _thread_sys_FOO is the real stub and FOO is a weak alias. For some of them, this is needed for cancellation handling. From discussions with fgsch@, ok millert@

known good version of ldstub in the kernel. (It's finally in, aja!) ok kettenis@
2011-10-13Increase the stack offset for the new rthread from (BIAS+128) toPhilip Guenthe
(BIAD+CC64FSZ) so that there's sufficient space even when _rthread_start is compiled without optimization. Also, clear the frame pointer to help make gdb happier. ok kettenis@

Tune the asm slightly to avoid using the stack and use smaller instructions. Pass threxit() a NULL pointer. seemed okay to kettenis@
