417d444e25 By default, don't compile in counters of calls to various time
query functions in the kernel, as these effectively serialize
parallel calls to the gettimeofday(2) system call, as well as
other kernel services that use timestamps.

Use the NetBSD version of the fix (kern_tc.c:1.32 by ad@) as
they have picked up our timecounter code and also ran into the
same problem.

4aae6c65e1 Decompose the global UNIX domain sockets rwlock into two different
locks: a global list/counter/generation counter protected by a new
mutex unp_list_lock, and a global linkage rwlock, unp_global_rwlock,
which protects the connections between UNIX domain sockets.

This eliminates conditional lock acquisition that was previously a
property of the global lock being held over sonewconn() leading to a
call to uipc_attach(), which also required the global lock, but
couldn't rely on it as other paths existed to uipc_attach() that
didn't hold it: now uipc_attach() uses only the list lock, which
follows the linkage lock in the lock order.  It may also reduce
contention on the global lock for some workloads.

Add global UNIX domain socket locks to hard-coded witness lock
order.

0f248d82f6 Don't disable CR-to-NL translation when waiting for data to arrive.
A difference between the old and the new TTY layer is that the new
implementation does not perform any post-processing before returning
data back to userspace when calling read().

sh(1)'s read turns the TTY into a raw mode before calling select(). This
means that the first character will not receive any ICRNL processing.
Inherit this flag from the original terminal attributes.

Even though this issue is not present on RELENG_*, I'm MFCing it to make
sh(1) in jails behave better.

directory of a vnode to find a dirent with a matching file number.  The
name from that dirent is then used to provide the component name.

 * Set up default date after parsing the string so that we

25330cae20 Add static DTrace probes for MAC Framework access control checks and
privilege grants so that dtrace can be more easily used to monitor
the security decisions being generated by the MAC Framework following
policy invocation.

Successful access control checks will be reported by:

  mac_framework:kernel:<entrypoint>:mac_check_ok

Failed access control checks will be reported by:

  mac_framework:kernel:<entrypoint>:mac_check_err

Successful privilege grants will be reported by:

  mac_framework:kernel:priv_grant:mac_grant_ok

Failed privilege grants will be reported by:

  mac_framework:kernel:priv_grant:mac_grant_err

In all cases, the return value (always 0 for _ok, otherwise an errno
for _err) will be reported via arg0 on the probe, and subsequent
arguments will hold entrypoint-specific data, in a style similar to
privilege tracing.

f18c279752 When resetting a BPF descriptor, properly check that zero-copy buffers
are not currently owned by userspace before clearing or rotating them.

Otherwise we may not play by the rules of the shared memory protocol,
potentially corrupting packet data or causing userspace applications
that are playing by the rules to spin due to being notified that a
buffer is complete but the shared memory header not reflecting that.

This behavior was seen with pflogd by a number of reporters; note that
this fix is not sufficient to get pflogd properly working with
zero-copy BPF, due to pflogd opening the BPF device before forking,
leading to the shared memory buffer not being propery inherited in the
privilege-separated child.  We're still deciding how to fix that
problem.

This change exposes buffer-model specific strategy information in
reset_d(), which will be fixed at a later date once we've decided how
best to improve the BPF buffer abstraction.

6181b4b9e4 Revert the part of change 107879 that employs the unused bytes after
the disklabel in the 2nd sector for boot code. Even with both UFS1
and UFS2 supported, there's enough bytes left that we don't have to
nibble from the disklabel.
Thus, the entire 2nd sector is now reserved for the disklabel, which
makes the bootcode compatible again with disklabels that have more
than 8 partitions -- such as those created and supported by gpart.

i386: 135 bytes available
amd64: 151 bytes available

o add Transaction Translator support (still missing ISOC xfers)
o add EHCI_SCFLG_BIGEMMIO flag to force big-endian byte-select to be
  set in USBMODE
o split reset work into new public routine ehci_reset so bus shim drivers
  can force big-endian byte-select before ehci_init
o enable TT and big-endian MMIO
o force a reset before ehci_init to get byte-select setup

Also go back to using USB_EHCI_BIG_ENDIAN_DESC at compile time to enable the
byteswapping and reduce diffs to the original commits.

This fixes the new USB stack on the Cambria board.
