yamt 5df39bb5be sa_makeupcalls: don't allocate big structures on stack. 2006-06-25 08:05:36 +00:00
yamt bc4977819f 1. implement solaris-like vmem. (still primitive, though) 
2. implement solaris-like kmem_alloc/free api, using #1.
   (note: this implementation is backed by kernel_map, thus can't be
   used from interrupt context.)

mrg 8075fe8705 don't put the bpendtsleep handy breakpoint in sun2 kernels as the 
output asm includes it twice causing multiply-defined symbols.

drochner 99f30cd9d2 add a comment telling which structure members are zero-initialized, 
as requested by YAMAMOTO Takashi
 2006-06-23 16:17:23 +00:00
yamt e408053d1b fix a simonb-timecounters regression. 
the precision of getnanotime() is not suitable for file timestamps.
esp. when it's nfs-exported.

- introduce vfs_timestamp().
  (the name is from freebsd.  currently merely a wrapper of nanotime())
- for ufs-like filesystems, use it rather than getnanotime().

XXX check other filesystems.

drochner 9b00231778 zero-init callback_head by memset(). code is 12 bytes shorter 2006-06-21 17:16:00 +00:00
christos ece76dd170 Don't leak memory on success. Allocate only the type of struct that we'll 
need for efficiency.

yamt 7d3142aa6a - introduce vfs_composefh() and use it where appropriate. 
- fix lock/unlock mismatch in sys_getfh.

yamt 7b37f4549b sysctl_security_setidcorename: don't allocate MAXPATHLEN bytes on stack. 2006-06-17 06:54:58 +00:00
dyoung 5174aa84b6 The UID_MAX limit is not enforced by syscalls such as setreuid(2), 
so I remove the assertion uid >= 0 && uid <= UID_MAX.  This squashes
a bug where Quagga would panic my machine by passing a UID outside
the range [0, UID_MAX].

AFAICT, this restores the historical (pre-kauth) behavior.

It is likely that GIDs do not satisfy the assertion gid >= 0 &&
gid <= GID_MAX, so remove that, too.

Patch from elad.

ginsbach d05e0bc3e8 Add EAFNOSUPPORT as a possible error if the address family is not 
supported.  This adds further differentiation between which argument to
socket(2) caused the error.  No longer are invalid domain (address family)
errors classified as ENOPROTOSUPPORT errors.  This should make socket(2)
conform to current POSIX and X/Open standards.  Fixes PR/33676.

kardel de4337ab21 merge FreeBSD timecounters from branch simonb-timecounters 
- struct timeval time is gone
  time.tv_sec -> time_second
- struct timeval mono_time is gone
  mono_time.tv_sec -> time_uptime
- access to time via
	{get,}{micro,nano,bin}time()
	get* versions are fast but less precise
- support NTP nanokernel implementation (NTP API 4)
- further reading:
