5eb4e81776 If a rpc for quota values fails with ENOTCONN translate this to ENOENT - we 
certainly don't have any quotas if they are disabled on the file server.
This silences warnings from things like "quota -u -v" when NFS mounts
are present and no quotas are in use on the file server.

dc2ecd830b libossaudio minor version bump to signify new ioctls. 2014-05-18 10:36:34 +00:00
nat
a8ba8ad76b Adds ioctls and defines for OSSv4 compatibility. 
The ioctl definitions and accompanying structures were
taken from FreeBSD's soundcard.h, hopefully providing
some binary compatibility.

The ioctls are as follows:
	SNDCTL_SYSINFO: Returns a structure containing
		details about the audio device.
	SNDCTL_ENGINEINFO - SNDCTL_AUDIOINFO: Returns a
		structure with playback/recording
		characteristics.
	SNDCTL_DSP_GETPLAYVOL, SNDCTL_DSP_SETPLAYVOL,
	SNDCTL_DSP_GETRECVOL, SNDCTL_DSP_SETRECVOL:
		Retrieves/Sets Playback/Recording volume.
	SNDCTL_DSP_SKIP - SNDCTL_DSP_SILENCE: These ioctls
		were intended to manipulate the underlying
		audio buffer skip or insert silence.  These
		return EINVAL.

SOUND_VERSION is unchanged, but is definable,  It will be
changed when the mixer OSSv4 ioctls are written.

66df54162c On sh3 __udivsi3 is gcc "millicode" with special calling convention 
(less registers clobbered than usual).  Each DSO that needs it gets
its own hidden copy from libgcc.a.  Do not compile udivsi3.c for sh3
here since this C version doesn't conform to what gcc expects and
overrides the libgcc.a version.

This makes binaries compiled with gcc4.8 work.  The issue was not
exposed with gcc4.5 since it uses different division strategy by
default.

0f547b99f1 Simplify somewhat: this is C not FORTRAN-IV - we have structures! 
Directly us 'ieee_double_shape_type' when ripping apart the fp number
  to avoid an extra store-load in 'STRICT_ASSIGN'.
Keep 'k' as the exponent, only do 'k << 20' when generating the fp number
  from it.
Fix infinity and underflow returns on i386 - because the value is returned
  in %st0 (x87 stack) we have to generate a long double error value.
The returned value for integers -1023 and below (which should be denormal
  fp valuesr) are 'just plain wrong' (tm).

ec1660cff5 Fix overflow and underflow on i386. 
The return value of a 'float' function is in the x87 %st(0) register.
This is an 80bit 'long double' register.
If you multiply 0x1p100f by 0x1p100f the caller sees 0x1p200 - not the
  expected infinity.
So use a 'double' value which goes through a store-load sequence to generate
  the required exception and value.

092f718fed There is some very odd code in s_exp2.c that only works if 'double' 
values are rounded to 53 bit mantissa in teh x87 registers.
This hasn't been true since Nov 11 2013.
Forcing a store-load for 'double' in STRICT_ASSIGN() seems to fix things
  (at least enough for the few random test cases).
I suspect the code could be changed so that the number of mantissa bits
  didn't matter.

77e93a9cb9 Drop in a fabs() after the fsqrt(). 
While it may seem pointless, it the rouding mode is set to round towards
minus infinity then acos(-1) calculates atan2(sqrt(1.0 - 1.0), -1) the subtract
generates -0.0 which sqrt() preserves.
atan2(-0, -1) is -pi, but acos(-1) is expected to be +pi.
This might 'fix' the test failures seen in some environments, but they
are not failing due to an obvously incorrent x87 rounding mode.

afa90f2bf5 prepare for moving GCC 4.5 into gcc.old: 
- convert to using ${EXTERNAL_GCC_SUBDIR}
- define base-external-gpl3-gcc* subdir as GCC_SUBDIR
- use <bsd.init.mk> over <bsd.own.mk> for a bunch of places; mostly
  because it arranges for ../Makefile.inc to be included earlier, and
  don't bother including the latter if the former is already included.
- move all .PATH: settings after <bsd.{own,lib}.mk> so that all
  valid variables are set before it is evaluated
- rename mknative-gcc* to match their subdir name.

XXX the relationship between the Makefile.inc/Makefile.gcc_path files
    is kind of sketchy, it would be great if this was fixed.

2e17c78b61 pthread__mutex_lock_slow: fix the handling of a potential race with the 
non-interlocked CAS in the fast unlock path -- it is unsafe to test for
the waiters-bit while the owner thread is running, we have to spin for
the owner or its state change to be sure about the presence of the bit.
Split off the logic into the pthread__mutex_setwaiters() routine.

This is a partial fix to the named lockup problem (also see PR/44756).
It seems there is another race which can be reproduced on faster CPUs.

de79b4937c PR/44756: Sad Clouds: Prevent leakage of errno = ESRCH from _lwp_park. This 
has two parts:
	- in pthread_cond_timedwait() if the thread we are trying to unpark
	  exited, retry the the _lwp_park call without it.
	- pthread_mutex() was affecting errno since it is calling _lwp_park()
	  from pthread_mutex_lock_slow(). preserve the original errno.
Note that the example problem still causes an occassional deadlock on machines
with many CPUs and it is the same deadlock we observe with named.
