being restricted to the #!/bin/sh used to run atf; (2) you can tell what
happened when it fails, since it does currently fail; (3) it runs all the
cases even when some of them don't work, and fails only at the end.
- bsdtar is using the hardlink resolver code from libarchive now,
making it generate correct links for newc format
- fix a number of non-exploitable integer and buffer overflows
- SIGINFO/SIGUSR1 support for bsdtar
- bsdtar -s support
- better mtree support, it should now be able to handle the full syntax
of NetBSD's mtree
- handle extraction of archives where hardlink and linked to entry don't
agree on the permission (base.tgz has such entries for systat)
AMD K8 and newer will trap when enabling the NX support outside PAE
paging mode. The AMD64 wake code was restoring the MSR EFER to switch to
Long Mode and naturally didn't have paging enabled at that point.
While this works fine with Intel CPUs, it resulted in an immediate
reboot with AMD processors.
Fixed by a joint brain storming session of jmcneill@, cegger@ and
myself, based on some input from the hardware developers. This fixes
PR 38587.
SCHED_FIFO threads
- Change condvar sync so that we never take the condvar's spinlock without
first holding the caller-provided mutex. Previously, the spinlock was only
taken without the mutex in an error path, but it was enough to trigger the
problem described in the PR.
- Even with this change, applications calling pthread_cond_signal/broadcast
without holding the interlocking mutex are still subject to the problem
described in the PR. POSIX discourages this saying that it leads to
undefined scheduling behaviour, which seems good enough for the time being.
- Elsewhere, use a hash of mutexes instead of per-object spinlocks to
synchronize entry/exit from sleep queues.
- Simplify how sleep queues are maintained.
Also output any detected errata at verbose, rather than debug, level so
they can be seen with dmesg, and at least have a clue if a BIOS update
would fix the errata.
errata:
254: Internal Resource Livelock Involving Cached TLB Reload
261: Processor May Stall Entering Stop-Grant Due to Pending Data
Cache Scrub
298: L2 Eviction May Occur During Processor Operation To Set
Accessed or Dirty Bit
309: Processor Core May Execute Incorrect Instructions on
Concurrent L2 and Northbridge Response
We now wrapper the open call for a module with module_open. It first
attempts to open the module_path munged path, if this fails it then tries
to open the original path.
This allows tftp files to be located correctly.
