If you try to grow a 'large' (at least half a page) allocation with
realloc(3), it'll try to extend the memory mapping for it and if that
works it won't need to move it.
Currently, it does that by using mquery(2) to see if that area is
available and if so then trying to mmap it, munmaping it
fseek(3) is implemented by just calling fseeko(3), the POSIX addition
version that takes an off_t instead of a long:
int
fseek(FILE *fp, long offset, int whence)
{
return (fseeko(fp, offset, whence));
}
...so there's no reason for libc to be using fseek() internally, as that
just loses

This diff replaces most of the rttimer with a timeout(9) call.
Instead of running a 1 second timer all the time it runs idividual
timeouts for each rttimer object.
rt_timer_remove_all() needs to be careful to not remove the rttimer object
while the timeout callback is running or up to be run.

The NFS subsystem is not MP-safe yet. Take this into account
in the NFS server socket upcall by locking the kernel.
This might help with the NFS server hanging that was seen recently
as a result of the now-reverted selwakeup()-to-KNOTE() conversion.
Unfortunately, I have not been able to confirm
I made a couple new versions of a new kind of arc4random_uniform-like
function and some example functions which use them. Instead of having a
sufficiently large random number greater than the modulus, I pick a random
number using arc4random() from a bitfield where the length of the bitfield
is
10 matches
