e5f49cece3 Regen: pad off_t args in pread/pwrite/preadv/pwritev. 1998-07-02 01:24:24 +00:00

d4e618b3a5 Argh, pad the off_t args in pread/pwrite/preadv/pwritev. System call 
numbers don't change since the window of brokenness was so small (1 day).

f0dda0d383 Add positional read and write system calls: 
- pread() (#173) and pwrite() (#174), which are defined by XPG4.2.  System
  call numbers match Solaris.
- preadv() (#289) and pwritev() (#290), which are the positional cousins
  of readv() and writev(), but not defined by any standard.

3a1500efe9 Per X/Open CAE Spec Issue 5 Version 2, change the buffer size argument of 
readlink() from type `int' to type `size_t'.  This isn't an ABI change, since
the calling convention of our only LP64 platform (the Alpha) already promotes
this argument to a `long'.

This may not be the final action on this matter; readlink() still returns
an `int', which may change in a future revision of the standard.

b436157e65 Make proc0 use the statically-allocate vmspace0 again, and make it use 
the kernel's pmap, since proc0 (and other that share its address space)
are kernel-only processes, and should never contain userspace mappings.

This makes it easier to detect errors, like entering user mappings
for kernel processes, in pmap modules, and makes some sense, considering
that kernel processes are really just "thread contexts" for the kernel.

  specified by POSIX; the prefix is intended to reflect the semantics.)

The log is activated by the MALLOCLOG option, and the size of the

is 100000 entries).

	vm_page_physload() -- tell the VM system about an area of memory.
	vm_physseg_find() -- returns index in vm_physmem array that this
		address is in.
and several new versions of old functions/macros defined in vm_page.h.

this is the MI portion.  sparc, and then later i386 portions to come.

cc22126721 Implement passing credentials as ancillary data on Unix domain sockets, 
enabled with the LOCAL_CREDS socket option on the listener.  Semantics are
similar to BSD/OS's:
- Creds are available with first data on SOCK_STREAM, and with every datagram
  on SOCK_DGRAM.
- It is not possible to forge credentials.

Different in that:
- Different credential data structure (ours does not rely on the format
  of internal kernel data structures, and does not pass the login name).
- We can pass creds and file descriptors at the same time (this does not
  work in BSD/OS).

Luke Mewburn <lukem@netbsd.org> gets credit for inspiring me to implement
this.  :-)

2e85747e9e From 4.4BSD-Lite2 (noted by Frank van der Linden): 
so_linger is used as an argument to tsleep(), so was stuffed with
clockticks for the TCP linger time.  However, so_linger is set directly from
l_linger if the linger time is specified, and l_linger is seconds (although
this is not currently documented anywhere).  Fix this to set the TCP
linger time in seconds, and multiply so_linger by hz when tsleep() is
called to actually perform the linger.

94fa91f862 import chris torek's vfprintf() from libc [renamed to kprintf and all 
floating point stuff removed].

the new kprintf replaces the 3 different (and buggy) versions of
printf that were in the kernel before (kprintf, sprintf, and db_printf),
thus reducing duplicated code by 2/3's.   this fixes (or adds) several
printf formats.  examples:
 %#x   - previously only supported by db_printf [not printf/sprintf]
 %8.8s - printf would print "000chuck" for "chuck" before
 %5p   - printf would print "0x    1" for value 1 before

XXX: new kprintf still supports several non-standard '%' formats that
are supposed to eventually be removed:
  %: - passes an additional format string and argument list recursively
  %b - used to decode error registers
  %r - int, but print in radix "db_radix" [DDB only]
  %z - 'signed hex' [DDB only]
  %n - unsigned int, but print in radix "db_radix" [DDB only]

note that DDB's "%n" conflicts with standard "%n" which takes the
number of characters written so far and stores it into the integer
indicated by the "int *" pointer arg.  yuck!

while here, add comments for each function explaining what it is
supposed to do.
