# $FreeBSD$
#
# On the handling of kernel options
#
# All kernel options should be listed in NOTES, with suitable
# descriptions. Negative options (options that make some code not
2001-07-08 01:04:10 +00:00
# compile) should be commented out; LINT (generated from NOTES) should
# compile as much code as possible. Try to structure option-using
# code so that a single option only switch code on, or only switch
# code off, to make it possible to have a full compile-test. If
# necessary, you can check for COMPILING_LINT to get maximum code
# coverage.
#
# All new options shall also be listed in either "conf/options" or
2001-07-08 01:04:10 +00:00
# "conf/options.<machine>". Options that affect a single source-file
# <xxx>.[c|s] should be directed into "opt_<xxx>.h", while options
# that affect multiple files should either go in "opt_global.h" if
# this is a kernel-wide option (used just about everywhere), or in
# "opt_<option-name-in-lower-case>.h" if it affect only some files.
# Note that the effect of listing only an option without a
# header-file-name in conf/options (and cousins) is that the last
# convention is followed.
#
# This handling scheme is not yet fully implemented.
#
#
# Format of this file:
# Option name filename
#
# If filename is missing, the default is
# opt_<name-of-option-in-lower-case>.h
# Adaptec Array Controller driver options
AAC_DEBUG opt_aac.h # Debugging levels:

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. Significant coding contributions were made by Chris Faulhaber. Additional support was provided by Brian Feldman, Thomas Moestl, and Ilmar Habibulin.

At long last, commit the zero copy sockets code. MAKEDEV: Add MAKEDEV glue for the ti(4) device nodes. ti.4: Update the ti(4) man page to include information on the TI_JUMBO_HDRSPLIT and TI_PRIVATE_JUMBOS kernel options, and also include information about the new character device interface and the associated ioctls. man9/Makefile: Add jumbo.9 and zero_copy.9 man pages and associated links. jumbo.9: New man page describing the jumbo buffer allocator interface and operation. zero_copy.9: New man page describing the general characteristics of the zero copy send and receive code, and what an application author should do to take advantage of the zero copy functionality. NOTES: Add entries for ZERO_COPY_SOCKETS, TI_PRIVATE_JUMBOS, TI_JUMBO_HDRSPLIT, MSIZE, and MCLSHIFT. conf/files: Add uipc_jumbo.c and uipc_cow.c. conf/options: Add the 5 options mentioned above. kern_subr.c: Receive side zero copy implementation. This takes "disposable" pages attached to an mbuf, gives them to a user process, and then recycles the user's page. This is only active when ZERO_COPY_SOCKETS is turned on and the kern.ipc.zero_copy.receive sysctl variable is set to 1. uipc_cow.c: Send side zero copy functions. Takes a page written by the user and maps it copy on write and assigns it kernel virtual address space. Removes copy on write mapping once the buffer has been freed by the network stack. uipc_jumbo.c: Jumbo disposable page allocator code. This allocates (optionally) disposable pages for network drivers that want to give the user the option of doing zero copy receive. uipc_socket.c: Add kern.ipc.zero_copy.{send,receive} sysctls that are enabled if ZERO_COPY_SOCKETS is turned on. Add zero copy send support to sosend() -- pages get mapped into the kernel instead of getting copied if they meet size and alignment restrictions. uipc_syscalls.c:Un-staticize some of the sf* functions so that they can be used elsewhere. (uipc_cow.c) if_media.c: In the SIOCGIFMEDIA ioctl in ifmedia_ioctl(), avoid calling malloc() with M_WAITOK. Return an error if the M_NOWAIT malloc fails. The ti(4) driver and the wi(4) driver, at least, call this with a mutex held. This causes witness warnings for 'ifconfig -a' with a wi(4) or ti(4) board in the system. (I've only verified for ti(4)). ip_output.c: Fragment large datagrams so that each segment contains a multiple of PAGE_SIZE amount of data plus headers. This allows the receiver to potentially do page flipping on receives. if_ti.c: Add zero copy receive support to the ti(4) driver. If TI_PRIVATE_JUMBOS is not defined, it now uses the jumbo(9) buffer allocator for jumbo receive buffers. Add a new character device interface for the ti(4) driver for the new debugging interface. This allows (a patched version of) gdb to talk to the Tigon board and debug the firmware. There are also a few additional debugging ioctls available through this interface. Add header splitting support to the ti(4) driver. Tweak some of the default interrupt coalescing parameters to more useful defaults. Add hooks for supporting transmit flow control, but leave it turned off with a comment describing why it is turned off. if_tireg.h: Change the firmware rev to 12.4.11, since we're really at 12.4.11 plus fixes from 12.4.13. Add defines needed for debugging. Remove the ti_stats structure, it is now defined in sys/tiio.h. ti_fw.h: 12.4.11 firmware. ti_fw2.h: 12.4.11 firmware, plus selected fixes from 12.4.13, and my header splitting patches. Revision 12.4.13 doesn't handle 10/100 negotiation properly. (This firmware is the same as what was in the tree previously, with the addition of header splitting support.) sys/jumbo.h: Jumbo buffer allocator interface. sys/mbuf.h: Add a new external mbuf type, EXT_DISPOSABLE, to indicate that the payload buffer can be thrown away / flipped to a userland process. socketvar.h: Add prototype for socow_setup. tiio.h: ioctl interface to the character portion of the ti(4) driver, plus associated structure/type definitions. uio.h: Change prototype for uiomoveco() so that we'll know whether the source page is disposable. ufs_readwrite.c:Update for new prototype of uiomoveco(). vm_fault.c: In vm_fault(), check to see whether we need to do a page based copy on write fault. vm_object.c: Add a new function, vm_object_allocate_wait(). This does the same thing that vm_object allocate does, except that it gives the caller the opportunity to specify whether it should wait on the uma_zalloc() of the object structre. This allows vm objects to be allocated while holding a mutex. (Without generating WITNESS warnings.) vm_object_allocate() is implemented as a call to vm_object_allocate_wait() with the malloc flag set to M_WAITOK. vm_object.h: Add prototype for vm_object_allocate_wait(). vm_page.c: Add page-based copy on write setup, clear and fault routines. vm_page.h: Add page based COW function prototypes and variable in the vm_page structure. Many thanks to Drew Gallatin, who wrote the zero copy send and receive code, and to all the other folks who have tested and reviewed this code over the years.

(this is an extract from src/share/examples/atm/README) =================================== 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().
