2013-08-13Switch time_t, ino_t, clock_t, and struct kevent's ident and dataPhilip Guenther
members to 64bit types. Assign new syscall numbers for (almost all) the syscalls that involve the affected types, including anything with time_t, timeval, itimerval, timespec, rusage, dirent, stat, or kevent arguments. Add a d_off member to struct dirent and replace getdirentries() with getdents(), thus immensely simplifying and accelerating telldir/seekdir. Build perl with -DBIG_TIME. Bump the major on every single base library: the compat bits included here are only good enough to make the transition; the T32 compat option will be burned as soon as we've reached the new world are are happy with the snapshots for all architectures. DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead. Much assistance in fixing userland issues from deraadt@ and tedu@ and build assistance from todd@ and otto@
2013-08-12The ps flags are split between thread and process. It is usefulAlexander Bluhm
for ddb to show both. So or them together in the ps overview and list them explicitly for the specific thread. Also sync the ddb bit names with the define names. OK miod@

2013-06-11High memory page flipping for the buffer cache.Bob Beck
This change splits the buffer cache free lists into lists of dma reachable buffers and high memory buffers based on the ranges returned by pmemrange. Buffers move from dma to high memory as they age, but are flipped to dma reachable memory if IO is needed to/from and high mem buffer. The total amount of buffers allocated is now bufcachepercent of both the dma and the high memory region. This change allows the use of large buffer caches on amd64 using more than 4 GB of memory ok tedu@ krw@ - testing by many.

2013-06-06Prevent idle thread from being stolen on startup.Christiano F. Haesbaert
There is a race condition which might trigger a case where two cpus try to run the same idle thread. The problem arises when one cpu steals the idle proc of another cpu and this other cpu ends up running the idle thread via spc->spc_idleproc, resulting in two cpus trying to cpu_switchto(idleX). On startup, idle procs are scaterred around different runqueues, the decision for scheduling is: 1 look at my runqueue. 2 if empty, look at other dudes runqueue. 3 if empty, select idle proc via spc->spc_idleproc. The problem is that cpu0's idle0 might be running on cpu1 due to step 1 or 2 and cpu0 hits step 3. So cpu0 will select idle0, while cpu1 is in fact running it already. The solution is to never place idle on a runqueue, therefore being only selectable through spc->spc_idleproc. This race can be more easily triggered on a HT cpu on virtualized environments, where the guest more often than not doesn't have the cpu for itself, so timing gets shuffled. ok tedu@ guenther@ go ahead after t2k13 deraadt@

2013-06-01cleanup and consolidate the spinlock_lock (what a name!) code.Ted Unangst
it's now atomic_lock to better reflect its usage, and librthread now features a new spinlock that's really a ticket lock. thrlseep can handle both types of lock via a flag in the clock arg. (temp back compat hack) remove some old stuff that's accumulated along the way and no longer used. some feedback from dlg, who is concerned with all things ticket lock. (you need to boot a new kernel before installing librthread)
