Add code to make default mutexes adaptive if the ADAPTIVE_MUTEXES kernel
option is used (not on by default).
- In the case of trying to lock a mutex, if the MTX_CONTESTED flag is set,
then we can safely read the thread pointer from the mtx_lock member while
holding sched_lock. We then examine the thread to see if it is currently
executing on another CPU. If it is, then we keep looping instead of
blocking.
- In the case of trying to unlock a mutex, it is now possible for a mutex
to have MTX_CONTESTED set in mtx_lock but to not have any threads
actually blocked on it, so we need to handle that case. In that case,
we just release the lock as if MTX_CONTESTED was not set and return.
- We do not adaptively spin on Giant as Giant is held for long times and
it slows SMP systems down to a crawl (it was taking several minutes,
like 5-10 or so for my test alpha and sparc64 SMP boxes to boot up when
they adaptively spinned on Giant).
- We only compile in the code to do this for SMP kernels, it doesn't make
sense for UP kernels.

KTRACE
|
Overhaul the ktrace subsystem a bit. For the most part, the actual vnode
operations to dump a ktrace event out to an output file are now handled
asychronously by a ktrace worker thread. This enables most ktrace events
to not need Giant once p_tracep and p_traceflag are suitably protected by
the new ktrace_lock.
There is a single todo list of pending ktrace requests. The various
ktrace tracepoints allocate a ktrace request object and tack it onto the
end of the queue. The ktrace kernel thread grabs requests off the head of
the queue and processes them using the trace vnode and credentials of the
thread triggering the event.
Since we cannot assume that the user memory referenced when doing a
ktrgenio() will be valid and since we can't access it from the ktrace
worker thread without a bit of hassle anyways, ktrgenio() requests are
still handled synchronously. However, in order to ensure that the requests
from a given thread still maintain relative order to one another, when a
synchronous ktrace event (such as a genio event) is triggered, we still put
the request object on the todo list to synchronize with the worker thread.
The original thread blocks atomically with putting the item on the queue.
When the worker thread comes across an asynchronous request, it wakes up
the original thread and then blocks to ensure it doesn't manage to write a
later event before the original thread has a chance to write out the
synchronous event. When the original thread wakes up, it writes out the
synchronous using its own context and then finally wakes the worker thread
back up. Yuck. The sychronous events aren't pretty but they do work.
Since ktrace events can be triggered in fairly low-level areas (msleep()
and cv_wait() for example) the ktrace code is designed to use very few
locks when posting an event (currently just the ktrace_mtx lock and the
vnode interlock to bump the refcoun on the trace vnode). This also means
that we can't allocate a ktrace request object when an event is triggered.
Instead, ktrace request objects are allocated from a pre-allocated pool
and returned to the pool after a request is serviced.
The size of this pool defaults to 100 objects, which is about 13k on an
i386 kernel. The size of the pool can be adjusted at compile time via the
KTRACE_REQUEST_POOL kernel option, at boot time via the
kern.ktrace_request_pool loader tunable, or at runtime via the
kern.ktrace_request_pool sysctl.
If the pool of request objects is exhausted, then a warning message is
printed to the console. The message is rate-limited in that it is only
printed once until the size of the pool is adjusted via the sysctl.
I have tested all kernel traces but have not tested user traces submitted
by utrace(2), though they should work fine in theory.
Since a ktrace request has several properties (content of event, trace
vnode, details of originating process, credentials for I/O, etc.), I chose
to drop the first argument to the various ktrfoo() functions. Currently
the functions just assume the event is posted from curthread. If there is
a great desire to do so, I suppose I could instead put back the first
argument but this time make it a thread pointer instead of a vnode pointer.
Also, KTRPOINT() now takes a thread as its first argument instead of a
process. This is because the check for a recursive ktrace event is now
per-thread instead of process-wide.
Tested on: i386

Introduce support for POSIX.1e ACLs on UFS-based file systems. This
implementation is still experimental, and while fairly broadly tested,
is not yet intended for production use. Support for POSIX.1e ACLs on
UFS will not be MFC'd to RELENG_4.
This implementation works by providing implementations of VOP_[GS]ETACL()
for FFS, as well as modifying the appropriate access control and file
creation routines. In this implementation, ACLs are backed into extended
attributes; the base ACL (owner, group, other) permissions remain in the
inode for performance and compatibility reasons, so only the extended and
default ACLs are placed in extended attributes. The logic for ACL
evaluation is provided by the fs-independent kern/kern_acl.c.
o Introduce UFS_ACL, a compile-time configuration option that enables
support for ACLs on FFS (and potentially other UFS-based file systems).
o Introduce ufs_getacl(), ufs_setacl(), ufs_aclcheck(), which
respectively get, set, and check the ACLs on the passed vnode.
o Introduce ufs_sync_acl_from_inode(), ufs_sync_inode_from_acl() to
maintain access control information between inode permissions and
extended attribute data.
o Modify ufs_access() to load a file access ACL and invoke
vaccess_acl_posix1e() if ACLs are available on the file system
o Modify ufs_mkdir() and ufs_makeinode() to associate ACLs with newly
created directories and files, inheriting from the parent directory's
default ACL.
o Enable these new vnode operations and conditionally compiled code
paths if UFS_ACL is defined.
A few notes:
o This implementation is fairly widely tested, but still should be
considered experimental.
o Currently, ACLs are not exported via NFS, instead, the summarizing
file mode/etc from the inode is. This results in conservative
protection behavior, similar to the behavior of ACL-nonaware programs
acting locally.
o It is possible that underlying binary data formats associated with
this implementation may change. Consumers of the implementation
should expect to find their local configuration obsoleted in the
next few months, resulting in possible loss of ACL data during an
upgrade.
o The extended attributes interface and implementation is still
undergoing modification to address portable interface concerns, as
well as performance.
o Many applications do not yet correctly handle ACLs. In general,
due to the POSIX.1e ACL model, behavior of ACL-unaware applications
will be conservative with respects to file protection; some caution
is recommended.
o Instructions for configuring and maintaining ACLs on UFS will be
committed in the near future; in the mean time it is possible to
reference the README included in the last UFS ACL distribution
placed in the TrustedBSD web site:
http://www.TrustedBSD.org/downloads/
Substantial debugging, hardware, travel, or connectivity support for this
project was provided by: BSDi, Safeport Network Services, and NAI Labs.

UFS_EXTATTR_AUTOSTART opt_ufs.h
|
Introduce extended attribute support for FFS, allowing arbitrary
(name, value) pairs to be associated with inodes. This support is
used for ACLs, MAC labels, and Capabilities in the TrustedBSD
security extensions, which are currently under development.
In this implementation, attributes are backed to data vnodes in the
style of the quota support in FFS. Support for FFS extended
attributes may be enabled using the FFS_EXTATTR kernel option
(disabled by default). Userland utilities and man pages will be
committed in the next batch. VFS interfaces and man pages have
been in the repo since 4.0-RELEASE and are unchanged.
o ufs/ufs/extattr.h: UFS-specific extattr defines
o ufs/ufs/ufs_extattr.c: bulk of support routines
o ufs/{ufs,ffs,mfs}/*.[ch]: hooks and extattr.h includes
o contrib/softupdates/ffs_softdep.c: extattr.h includes
o conf/options, conf/files, i386/conf/LINT: added FFS_EXTATTR
o coda/coda_vfsops.c: XXX required extattr.h due to ufsmount.h
(This should not be the case, and will be fixed in a future commit)
Currently attributes are not supported in MFS. This will be fixed.

HARP | Host ATM Research Platform
===================================
HARP 3
What is this stuff?
-------------------
The Advanced Networking Group (ANG) at the Minnesota Supercomputer Center,
Inc. (MSCI), as part of its work on the MAGIC Gigabit Testbed, developed
the Host ATM Research Platform (HARP) software, which allows IP hosts to
communicate over ATM networks using standard protocols. It is intended to
be a high-quality platform for IP/ATM research.
HARP provides a way for IP hosts to connect to ATM networks. It supports
standard methods of communication using IP over ATM. A host's standard IP
software sends and receives datagrams via a HARP ATM interface. HARP provides
functionality similar to (and typically replaces) vendor-provided ATM device
driver software.
HARP includes full source code, making it possible for researchers to
experiment with different approaches to running IP over ATM. HARP is
self-contained; it requires no other licenses or commercial software packages.
HARP implements support for the IETF Classical IP model for using IP over ATM
networks, including:
o IETF ATMARP address resolution client
o IETF ATMARP address resolution server
o IETF SCSP/ATMARP server
o UNI 3.1 and 3.0 signalling protocols
o Fore Systems's SPANS signalling protocol
What's supported
----------------
The following are supported by HARP 3:
o ATM Host Interfaces
- FORE Systems, Inc. SBA-200 and SBA-200E ATM SBus Adapters
- FORE Systems, Inc. PCA-200E ATM PCI Adapters
- Efficient Networks, Inc. ENI-155p ATM PCI Adapters
o ATM Signalling Protocols
- The ATM Forum UNI 3.1 signalling protocol
- The ATM Forum UNI 3.0 signalling protocol
- The ATM Forum ILMI address registration
- FORE Systems's proprietary SPANS signalling protocol
- Permanent Virtual Channels (PVCs)
o IETF "Classical IP and ARP over ATM" model
- RFC 1483, "Multiprotocol Encapsulation over ATM Adaptation Layer 5"
- RFC 1577, "Classical IP and ARP over ATM"
- RFC 1626, "Default IP MTU for use over ATM AAL5"
- RFC 1755, "ATM Signaling Support for IP over ATM"
- RFC 2225, "Classical IP and ARP over ATM"
- RFC 2334, "Server Cache Synchronization Protocol (SCSP)"
- Internet Draft draft-ietf-ion-scsp-atmarp-00.txt,
"A Distributed ATMARP Service Using SCSP"
o ATM Sockets interface
- The file atm-sockets.txt contains further information
What's not supported
--------------------
The following major features of the above list are not currently supported:
o UNI point-to-multipoint support
o Driver support for Traffic Control/Quality of Service
o SPANS multicast and MPP support
o SPANS signalling using Efficient adapters
This software was developed under the sponsorship of the Defense Advanced
Research Projects Agency (DARPA).

- Make the mutex code almost completely machine independent. This greatly
reducues the maintenance load for the mutex code. The only MD portions
of the mutex code are in machine/mutex.h now, which include the assembly
macros for handling mutexes as well as optionally overriding the mutex
micro-operations. For example, we use optimized micro-ops on the x86
platform #ifndef I386_CPU.
- Change the behavior of the SMP_DEBUG kernel option. In the new code,
mtx_assert() only depends on INVARIANTS, allowing other kernel developers
to have working mutex assertiions without having to include all of the
mutex debugging code. The SMP_DEBUG kernel option has been renamed to
MUTEX_DEBUG and now just controls extra mutex debugging code.
- Abolish the ugly mtx_f hack. Instead, we dynamically allocate
seperate mtx_debug structures on the fly in mtx_init, except for mutexes
that are initiated very early in the boot process. These mutexes
are declared using a special MUTEX_DECLARE() macro, and use a new
flag MTX_COLD when calling mtx_init. This is still somewhat hackish,
but it is less evil than the mtx_f filler struct, and the mtx struct is
now the same size with and without mutex debugging code.
- Add some micro-micro-operation macros for doing the actual atomic
operations on the mutex mtx_lock field to make it easier for other archs
to override/optimize mutex ops if needed. These new tiny ops also clean
up the code in some places by replacing long atomic operation function
calls that spanned 2-3 lines with a short 1-line macro call.
- Don't call mi_switch() from mtx_enter_hard() when we block while trying
to obtain a sleep mutex. Calling mi_switch() would bogusly release
Giant before switching to the next process. Instead, inline most of the
code from mi_switch() in the mtx_enter_hard() function. Note that when
we finally kill Giant we can back this out and go back to calling
mi_switch().
