Update for the KDB framework: o Rename WITNESS_DDB to WITNESS_KDB. In the new world order KDB is the acronym to use for debugging related code. The DDB option is used to enable the DDB debugger backend only. o Likewise, rename DDB_TRACE to KDB_TRACE, rename DDB_UNATTENDED to KDB_UNATTENDED and rename SC_HISTORY_DDBKEY to SC_HISTORY_KDBKEY. o Remove DDB_NOKLDSYM. The new DDB backend supports pre-linker symbol lookups as well as KLD symbol lookups at the same time. o Remove GDB_REMOTE_CHAT. The GDB protocol hacks to allow this are FreeBSD specific.

# Miscellaneous options.
Add "options ADAPTIVE_GIANT" which causes Giant to also be treated in an adaptive fashion when adaptive mutexes are enabled. The theory behind non-adaptive Giant is that Giant will be held for long periods of time, and therefore spinning waiting on it is wasteful. However, in MySQL benchmarks which are relatively Giant-free, running Giant adaptive makes an observable difference on SMP (5% transaction rate improvement). As such, make adaptive behavior on Giant an option so it can be more widely benchmarked.

Add a new CODA_COMPAT_5 option, which requests support for the old Coda 5.x interface instead of the new one. Create a new coda5.ko module that supports the 5.x interface, and make the existing coda.ko module use the new 6.x interface. These modules cannot both be loaded at the same time. Obtained from: Jan Harkes & the coda-6.0.2 distribution, NetBSD (drochner) (CODA_COMPAT_5 option).

There are currently three known issues which may force people to need the NO_GEOM option: boot0cfg/fdisk: Tries to update the MBR while it is being used to control slices. GEOM does not allow this as a direct operation. SCSI floppy drives: Appearantly the scsi-da driver return "EBUSY" if no media is inserted. This is wrong, it should return ENXIO.

GEOM_APPLE opt_geom.h
Add Geom Based Disk Encryption to the tree. This is an encryption module designed for to secure denial of access to the contents of "cold disks" with or without destruction activation. Major features: * Based on AES, MD5 and ARC4 algorithms. * Four cryptographic barriers: 1) Pass-phrase encrypts the master key. 2) Pass-phrase + Lock data locates master key. 3) 128 bit key derived from 2048 bit master key protects sector key. 3) 128 bit random single-use sector keys protect data payload. * Up to four different changeable pass-phrases. * Blackening feature for provable destruction of master key material. * Isotropic disk contents offers no information about sector contents. * Configurable destination sector range allows steganographic deployment. This commit adds the kernel part, separate commits will follow for the userland utility and documentation. This software was developed for the FreeBSD Project by Poul-Henning Kamp and NAI Labs, the Security Research Division of Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035 ("CBOSS"), as part of the DARPA CHATS research program.

GEOM_CONCAT opt_geom.h
Add "GEOM_FOX", a class which detects and selects between multiple redundant paths to the same device. This class reacts to a label in the first sector of the device, which is created the following way: # "0123456789abcdef012345..." # "<----magic-----><-id-...> echo "GEOM::FOX someid" | dd of=/dev/da0 conv=sync NB: Since the fact that multiple disk devices are in fact the same device is not known to GEOM, the geom taste/spoil process cannot fully catch all corner cases and this module can therefore be confused if you do the right wrong things. NB: The disk level drivers need to do the right thing for this to be useful, and that is not by definition currently the case.

GEOM_GPT opt_geom.h
Introduce GEOM_LABEL class. This class is used for detecting volume labels on file systems: UFS, MSDOSFS (FAT12, FAT16, FAT32) and ISO9660. It also provide native labelization (there is no need for file system). g_label_ufs.c is based on geom_vol_ffs from Gordon Tetlow. g_label_msdos.c and g_label_iso9660.c are probably hacks, I just found where volume labels are stored and I use those offsets here, but with this class it should be easy to do it as it should be done by someone who know how. Implementing volume labels detection for other file systems also should be trivial. New providers are created in those directories: /dev/ufs/ (UFS1, UFS2) /dev/msdosfs/ (FAT12, FAT16, FAT32) /dev/iso9660/ (ISO9660) /dev/label/ (native labels, configured with glabel(8)) Manual page cleanups and some comments inside were submitted by Simon L. Nielsen, who was, as always, very helpful. Thanks!

Some kernel threads try to do significant work, and the default KSTACK_PAGES doesn't give them enough stack to do much before blowing away the pcb. This adds MI and MD code to allow the allocation of an alternate kstack who's size can be speficied when calling kthread_create. Passing the value 0 prevents the alternate kstack from being created. Note that the ia64 MD code is missing for now, and PowerPC was only partially written due to the pmap.c being incomplete there. Though this patch does not modify anything to make use of the alternate kstack, acpi and usb are good candidates. Reviewed by: jake, peter, jhb

Retire MFS_ROOT and MFS_ROOT_SIZE options from the MFS implementation. Add MD_ROOT and MD_ROOT_SIZE options to the md driver. Make the md driver handle MFS_ROOT and MFS_ROOT_SIZE options for compatibility. Add md driver to GENERIC, PCCARD and LINT. This is a cleanup which removes the need for some of the worse hacks in MFS: We really want to have a rootvnode but MFS on a preloaded image doesn't really have one. md is a true device, so it is less trouble. This has been tested with make release, and if people remember to add the "md" pseudo-device to their kernels, PicoBSD should be just fine as well. If people have no other use for MFS, it can be removed from the kernel.

If the various threads are awakened in sequence then each thread may acquire and release the lock in question without contention resulting in fewer expensive unlock and lock operations. This old behavior of waking just the highest priority is still used if this option is specified. Making the algorithm conditional on a kernel option will allows us to benchmark both cases later and determine which one should be used by default. Requested by: tanimura-san

The other possibility is to initialize on the first use, and allow dynamic sysctl changes to parameters right until that point.

This mega-commit brings the following: . It makes cd9660 root f/s working again. . It makes CD9660 a new-style option. . It adds support to mount an ISO9660 multi-session CD-ROM as the root filesystem (the last session actually, but that's what is expected behaviour). Sigh. The CDIOREADTOCENTRYS did a copyout() of its own, and thus has been unusable for me for this work. Too bad it didn't simply stuff the max 100 entries into the struct ioc_read_toc_entry, but relied on a user supplied data buffer instead. :-( I now had to reinvent the wheel, and created a CDIOREADTOCENTRY ioctl command that can be used in a kernel context. While doing this, i noticed the following bogosities in existing CD-ROM drivers: wcd: This driver is likely to be totally bogus when someone tries two succeeding CDIOREADTOCENTRYS (or now CDIOREADTOCENTRY) commands with requesting MSF format, since it apparently operates on an internal table. scd: This driver apparently returns just a single TOC entry only for the CDIOREADTOCENTRYS command. I have only been able to test the CDIOREADTOCENTRY command with the cd(4) driver. I hereby request the respective maintainers of the other CD-ROM drivers to verify my code for their driver. When it comes to merging this CD-ROM multisession stuff into RELENG_2_2 i will only consider drivers where i've got a confirmation that it actually works.

SOFTUPDATES opt_ffs.h
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.

Bring in dirhash, a simple hash-based lookup optimisation for large directories. When enabled via "options UFS_DIRHASH", in-core hash arrays are maintained for large directories. These allow all directory operations to take place quickly instead of requiring long linear searches. For now anyway, dirhash is not enabled by default. The in-core hash arrays have a memory requirement that is approximately half the size of the size of the on-disk directory file. A number of new sysctl variables allow control over which directories get hashed and over the maximum amount of memory that dirhash will use: vfs.ufs.dirhash_minsize The minimum on-disk directory size for which hashing should be used. The default is 2560 (2.5k). vfs.ufs.dirhash_maxmem The system-wide maximum total memory to be used by dirhash data structures. The default is 2097152 (2MB). The current amount of memory being used by dirhash is visible through the read-only sysctl variable vfs.ufs.dirhash_maxmem. Finally, some extra sanity checks that are enabled by default, but which may have an impact on performance, can be disabled by setting vfs.ufs.dirhash_docheck to 0. Discussed on: -fs, -hackers

By popular request, add a workaround that allows large (>128GB or so) FAT32 filesystems to be mounted, subject to some fairly serious limitations. This works by extending the internal pseudo-inode-numbers generated from the file's starting cluster number to 64-bits, then creating a table mapping these into arbitrary 32-bit inode numbers, which can fit in struct dirent's d_fileno and struct vattr's va_fileid fields. The mappings do not persist across unmounts or reboots, so it's not possible to export these filesystems through NFS. The mapping table may grow to be rather large, and may grow large enough to exhaust kernel memory on filesystems with millions of files. Don't enable this option unless you understand the consequences.

NMBCLUSTERS opt_param.h
Implemented zero-copy TCP/IP extensions via sendfile(2) - send a file to a stream socket. sendfile(2) is similar to implementations in HP-UX, Linux, and other systems, but the API is more extensive and addresses many of the complaints that the Apache Group and others have had with those other implementations. Thanks to Marc Slemko of the Apache Group for helping me work out the best API for this. Anyway, this has the "net" result of speeding up sends of files over TCP/IP sockets by about 10X (that is to say, uses 1/10th of the CPU cycles) when compared to a traditional read/write loop.

NSFBUFS opt_param.h
Limit the amount of KVM reserved for the buffer cache and for swap-meta information. The default limits only effect machines with > 1GB of ram and can be overriden with two new kernel conf variables VM_SWZONE_SIZE_MAX and VM_BCACHE_SIZE_MAX, or with loader variables kern.maxswzone and kern.maxbcache. This has the effect of leaving more KVM available for sizing NMBCLUSTERS and 'maxusers' and should avoid tripups where a sysad adds memory to a machine and then sees the kernel panic on boot due to running out of KVM. Also change the default swap-meta auto-sizing calculation to allocate half of what it was previously allocating. The prior defaults were way too high. Note that we cannot afford to run out of swap-meta structures so we still stay somewhat conservative here.

IPFIREWALL_DEFAULT_TO_ACCEPT opt_ipfw.h
Convert ipfw to use PFIL_HOOKS. This is change is transparent to userland and preserves the ipfw ABI. The ipfw core packet inspection and filtering functions have not been changed, only how ipfw is invoked is different. However there are many changes how ipfw is and its add-on's are handled: In general ipfw is now called through the PFIL_HOOKS and most associated magic, that was in ip_input() or ip_output() previously, is now done in ipfw_check_[in|out]() in the ipfw PFIL handler. IPDIVERT is entirely handled within the ipfw PFIL handlers. A packet to be diverted is checked if it is fragmented, if yes, ip_reass() gets in for reassembly. If not, or all fragments arrived and the packet is complete, divert_packet is called directly. For 'tee' no reassembly attempt is made and a copy of the packet is sent to the divert socket unmodified. The original packet continues its way through ip_input/output(). ipfw 'forward' is done via m_tag's. The ipfw PFIL handlers tag the packet with the new destination sockaddr_in. A check if the new destination is a local IP address is made and the m_flags are set appropriately. ip_input() and ip_output() have some more work to do here. For ip_input() the m_flags are checked and a packet for us is directly sent to the 'ours' section for further processing. Destination changes on the input path are only tagged and the 'srcrt' flag to ip_forward() is set to disable destination checks and ICMP replies at this stage. The tag is going to be handled on output. ip_output() again checks for m_flags and the 'ours' tag. If found, the packet will be dropped back to the IP netisr where it is going to be picked up by ip_input() again and the directly sent to the 'ours' section. When only the destination changes, the route's 'dst' is overwritten with the new destination from the forward m_tag. Then it jumps back at the route lookup again and skips the firewall check because it has been marked with M_SKIP_FIREWALL. ipfw 'forward' has to be compiled into the kernel with 'option IPFIREWALL_FORWARD' to enable it. DUMMYNET is entirely handled within the ipfw PFIL handlers. A packet for a dummynet pipe or queue is directly sent to dummynet_io(). Dummynet will then inject it back into ip_input/ip_output() after it has served its time. Dummynet packets are tagged and will continue from the next rule when they hit the ipfw PFIL handlers again after re-injection. BRIDGING and IPFW_ETHER are not changed yet and use ipfw_chk() directly as they did before. Later this will be changed to dedicated ETHER PFIL_HOOKS. More detailed changes to the code: conf/files Add netinet/ip_fw_pfil.c. conf/options Add IPFIREWALL_FORWARD option. modules/ipfw/Makefile Add ip_fw_pfil.c. net/bridge.c Disable PFIL_HOOKS if ipfw for bridging is active. Bridging ipfw is still directly invoked to handle layer2 headers and packets would get a double ipfw when run through PFIL_HOOKS as well. netinet/ip_divert.c Removed divert_clone() function. It is no longer used. netinet/ip_dummynet.[ch] Neither the route 'ro' nor the destination 'dst' need to be stored while in dummynet transit. Structure members and associated macros are removed. netinet/ip_fastfwd.c Removed all direct ipfw handling code and replace it with the new 'ipfw forward' handling code. netinet/ip_fw.h Removed 'ro' and 'dst' from struct ip_fw_args. netinet/ip_fw2.c (Re)moved some global variables and the module handling. netinet/ip_fw_pfil.c New file containing the ipfw PFIL handlers and module initialization. netinet/ip_input.c Removed all direct ipfw handling code and replace it with the new 'ipfw forward' handling code. ip_forward() does not longer require the 'next_hop' struct sockaddr_in argument. Disable early checks if 'srcrt' is set. netinet/ip_output.c Removed all direct ipfw handling code and replace it with the new 'ipfw forward' handling code. netinet/ip_var.h Add ip_reass() as general function. (Used from ipfw PFIL handlers for IPDIVERT.) netinet/raw_ip.c Directly check if ipfw and dummynet control pointers are active. netinet/tcp_input.c Rework the 'ipfw forward' to local code to work with the new way of forward tags. netinet/tcp_sack.c Remove include 'opt_ipfw.h' which is not needed here. sys/mbuf.h Remove m_claim_next() macro which was exclusively for ipfw 'forward' and is no longer needed.

Add a facility for devices, specifically network interfaces, that require large to huge amounts of small or medium sized receive buffers. The problem with these situations is that they eat up the available DMA address space very quickly when using mbufs or even mbuf clusters. Additionally this facility provides a direct mapping between 32-bit integers and these buffers. This is needed for devices originally designed for 32-bit systems. Ususally the virtual address of the buffer is used as a handle to find the buffer as soon as it is returned by the card. This does not work for 64-bit machines and hence this mapping is needed.

NETATALK opt_atalk.h
Change the default disposition of debug.mpsafenet from 0 to 1, which will cause the network stack to operate without the Giant lock by default. This change has the potential to improve performance by increasing parallelism and decreasing latency in network processing. Due to the potential exposure of existing or new bugs, the following compatibility functionality is maintained: - It is still possible to disable Giant-free operation by setting debug.mpsafenet to 0 in loader.conf. - Add "options NET_WITH_GIANT", which will restore the default value of debug.mpsafenet to 0, and is intended for use on systems compiled with known unsafe components, or where a more conservative configuration is desired. - Add a new declaration, NET_NEEDS_GIANT("componentname"), which permits kernel components to declare dependence on Giant over the network stack. If the declaration is made by a preloaded module or a compiled in component, the disposition of debug.mpsafenet will be set to 0 and a warning concerning performance degraded operation printed to the console. If it is declared by a loadable kernel module after boot, a warning is displayed but the disposition cannot be changed. This is implemented by defining a new SYSINIT() value, SI_SUB_SETTINGS, which is intended for the processing of configuration choices after tunables are read in and the console is available to generate errors, but before much else gets going. This compatibility behavior will go away when we've finished the last of the locking work and are confident that operation is correct.

TCPDEBUG
Initial import of RFC 2385 (TCP-MD5) digest support. This is the first of two commits; bringing in the kernel support first. This can be enabled by compiling a kernel with options TCP_SIGNATURE and FAST_IPSEC. For the uninitiated, this is a TCP option which provides for a means of authenticating TCP sessions which came into being before IPSEC. It is still relevant today, however, as it is used by many commercial router vendors, particularly with BGP, and as such has become a requirement for interconnect at many major Internet points of presence. Several parts of the TCP and IP headers, including the segment payload, are digested with MD5, including a shared secret. The PF_KEY interface is used to manage the secrets using security associations in the SADB. There is a limitation here in that as there is no way to map a TCP flow per-port back to an SPI without polluting tcpcb or using the SPD; the code to do the latter is unstable at this time. Therefore this code only supports per-host keying granularity. Whilst FAST_IPSEC is mutually exclusive with KAME IPSEC (and thus IPv6), TCP_SIGNATURE applies only to IPv4. For the vast majority of prospective users of this feature, this will not pose any problem. This implementation is output-only; that is, the option is honoured when responding to a host initiating a TCP session, but no effort is made [yet] to authenticate inbound traffic. This is, however, sufficient to interwork with Cisco equipment. Tested with a Cisco 2501 running IOS 12.0(27), and Quagga 0.96.4 with local patches. Patches for tcpdump to validate TCP-MD5 sessions are also available from me upon request. Sponsored by: sentex.net

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).

Add a new kernel option, MALLOC_MAKE_FAILURES, which compiles in a debugging feature causing M_NOWAIT allocations to fail at a specified rate. This can be useful for detecting poor handling of M_NOWAIT: the most frequent problems I've bumped into are unconditional deference of the pointer even though it's NULL, and hangs as a result of a lost event where memory for the event couldn't be allocated. Two sysctls are added: debug.malloc.failure_rate How often to generate a failure: if set to 0 (default), this feature is disabled. Otherwise, the frequency of failures -- I've been using 10 (one in ten mallocs fails), but other popular settings might be much lower or much higher. debug.malloc.failure_count Number of times a coerced malloc failure has occurred as a result of this feature. Useful for tracking what might have happened and whether failures are being generated. Useful possible additions: tying failure rate to malloc type, printfs indicating the thread that experienced the coerced failure. Reviewed by: jeffr, jhb

Bring in MemGuard, a very simple and small replacement allocator designed to help detect tamper-after-free scenarios, a problem more and more common and likely with multithreaded kernels where race conditions are more prevalent. Currently MemGuard can only take over malloc()/realloc()/free() for particular (a) malloc type(s) and the code brought in with this change manually instruments it to take over M_SUBPROC allocations as an example. If you are planning to use it, for now you must: 1) Put "options DEBUG_MEMGUARD" in your kernel config. 2) Edit src/sys/kern/kern_malloc.c manually, look for "XXX CHANGEME" and replace the M_SUBPROC comparison with the appropriate malloc type (this might require additional but small/simple code modification if, say, the malloc type is declared out of scope). 3) Build and install your kernel. Tune vm.memguard_divisor boot-time tunable which is used to scale how much of kmem_map you want to allott for MemGuard's use. The default is 10, so kmem_size/10. ToDo: 1) Bring in a memguard(9) man page. 2) Better instrumentation (e.g., boot-time) of MemGuard taking over malloc types. 3) Teach UMA about MemGuard to allow MemGuard to override zone allocations too. 4) Improve MemGuard if necessary. This work is partly based on some old patches from Ian Dowse.

Add a overhaul of the soundchip initialization for the MSP34xx chipsets found only many tv-cards. We currently use more ore less evil hacks (slow_msp_audio sysctl) to configure the various variants of these chips in order to have stereo autodetection work. Nevertheless, this doesn't always work even though it _should_, according to the specs. This is, for example, the case for some popular Hauppauge models sold sold in Germany. However, the Linux driver always worked for me and others. Looking at the sourcecode you will find that the linux-driver uses a very much enhanced approach to program the various msp34xx chipset variants, which is also found in the specs for these chips. This is a port of the Linux MSP34xx code, written by Gerd Knorr <kraxel@bytesex.org>, who agreed to re-release his code under a BSD license for this port. A new config option "BKTR_NEW_MSP34XX_DRIVER" is added, which is required to enable the new driver. Otherwise the old code is used. The msp34xx.c file is diff-reduced to the linux-driver to make later modifications easier, thus it doesn't follow style(9) in most cases.

The DDB option is used to enable the DDB debugger backend only. o Likewise, rename DDB_TRACE to KDB_TRACE, rename DDB_UNATTENDED to KDB_UNATTENDED and rename SC_HISTORY_DDBKEY to SC_HISTORY_KDBKEY. o Remove DDB_NOKLDSYM. The new DDB backend supports pre-linker symbol lookups as well as KLD symbol lookups at the same time. o Remove GDB_REMOTE_CHAT. The GDB protocol hacks to allow this are FreeBSD specific. At the same time, the GDB protocol has packets for console output.

2000-10-27 03:00:28 +00:00
WITNESS_SKIPSPIN opt_witness.h
Major update to the way synchronization is done in the kernel. Highlights include: * Mutual exclusion is used instead of spl*(). See mutex(9). (Note: The alpha port is still in transition and currently uses both.) * Per-CPU idle processes. * Interrupts are run in their own separate kernel threads and can be preempted (i386 only).

# options for ACPI support
ACPI_DEBUG opt_acpi.h
Add OS layer ACPI mutex and threading support. - Temporary fix a bug of Intel ACPI CA core code. - Add OS layer ACPI mutex support. This can be disabled by specifying option ACPI_NO_SEMAPHORES. - Add ACPI threading support. Now that we have a dedicate taskqueue for ACPI tasks and more ACPI task threads can be created by specifying option ACPI_MAX_THREADS. - Change acpi_EvaluateIntoBuffer() behavior slightly to reuse given caller's buffer unless AE_BUFFER_OVERFLOW occurs. Also CM battery's evaluations were changed to use acpi_EvaluateIntoBuffer(). - Add new utility function acpi_ConvertBufferToInteger(). - Add simple locking for CM battery and temperature updating. - Fix a minor problem on EC locking. - Make the thermal zone polling rate to be changeable. - Change minor things on AcpiOsSignal(); in ACPI_SIGNAL_FATAL case, entering Debugger is easier to investigate the problem rather than panic.

ACPI_NO_SEMAPHORES opt_acpi.h
Add the ACPICA_PEDANTIC option which is off by default. Enabling it will enable strict checks of the AML. Our default behavior will be to relax checks to work on as many platforms as possible. Also clean up and document other ACPI options while I'm here.
2003-10-22 22:27:49 +00:00
ACPICA_PEDANTIC opt_acpi.h
Add refcounts to the "global" DEVFS inode slots, this allows us to recycle inodes after a destroy_dev() but not until all mounts have picked up the change. Add support for an overflow table for DEVFS inodes. The static table defaults to 1024 inodes, if that fills, an overflow table of 32k inodes is allocated. Both numbers can be changed at compile time, the size of the overflow table also with the sysctl vfs.devfs.noverflow. Use atomic instructions to barrier between make_dev()/destroy_dev() and the mounts. Add lockmgr() locking of directories for operations accessing or modifying the directory TAILQs. Various nitpicking here and there.

Add an option ED_NO_MIIBUS, which causes the `ed' driver to be built without support for miibus PHYs. Most ed cards don't need miibus support, so it's useful to be able to avoid the bloat of all the mii devices for small fixed-purpose kernels.

# ed driver
ED_NO_MIIBUS opt_ed.h
Break out obscure ISA cards into their own files, as well as ne2000 and wd80x3 support. Make the obscure ISA cards optional, and add those options to NOTES on i386 (note: the ifdef around the whole code is for module building). Tweak pc98 ed support to include wd80x3 too. Add goo for alpha too. The affected cards are the 3Com 3C503, HP LAN+ and SIC (whatever that is). I couldn't find any of these for sale on ebay, so they are untested. If you have one of these cards, and send it to me, I'll ensure that you have no future problems with it... Minor cleanups as well by using functions rather than cut and paste code for some probing operations (where the function call overhead is lost in the noise). Remove use of kvtop, since they aren't required anymore. This driver needs to get its memory mapped act together, however, and use bus space. It doesn't right now. This reduces the size of if_ed.ko from about 51k to 33k on my laptop.

Add code that will download firmware to a Symbol LA4100-series of CF cards. Since the firmware is hard coded into the kernel, I've made it a kernel option (WI_SYMBOL_FIRMWARE). Note: This only downloads into the RAM of these cards. It doesn't download into FLASH, and is somewhat limited. There needs to be a better way to deal, but this works for now. My Symbol LA4132 CF card works now. Obtained from: NetBSD

Kill count device support from config. I've changed the last few remaining consumers to have the count passed as an option. This is i4b, pc98/wdc, and coda. Bump configvers.h from 500013 to 600000. Remove heuristics that tried to parse "device ed5" as 5 units of the ed device. This broke things like the snd_emu10k1 device, which required quotes to make it parse right. The no-longer-needed quotes have been removed from NOTES, GENERIC etc. eg, I've removed the quotes from: device snd_maestro device "snd_maestro3" device snd_mss I believe everything will still compile and work after this.
