# Miscellaneous options.
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. Tested on: i386, alpha, sparc64

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.

Move the MSG* and SEM* options to opt_sysvipc.h Remove evil allocation macros from machdep.c (why was that there???) and use malloc() instead. Move paramters out of param.h and into the code itself. Move a bunch of internal definitions from public sys/*.h headers (without #ifdef _KERNEL even) into the code itself. I had hoped to make some of this more dynamic, but the cost of doing wakeups on all sleeping processes on old arrays was too frightening. The other possibility is to initialize on the first use, and allow dynamic sysctl changes to parameters right until that point. That would allow /etc/rc.sysctl to change SEM* and MSG* defaults as we presently do with SHM*, but without the nightmare of changing a running system.

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.

Introduce extended attribute support for FFS, allowing arbitrary (name, value) pairs to be associated with inodes.

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

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.

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_VERBOSE_LIMIT opt_ipfw.h
Allow a compile-time override of the ipfw deny rule. For a 'firewall' you don't want this (and the documentation explains why), but if you use ipfw as an as-needed casual filter as needed which normally runs as 'allow all' then having the kernel and /sbin/ipfw get out of sync is a *MAJOR* pain in the behind.

Add support for stealth forwarding (forwarding packets without touching their ttl). This can be used - in combination with the proper ipfw incantations - to make a firewall or router invisible to traceroute and other exploration tools. This behaviour is controlled by a sysctl variable (net.inet.ip.stealth) and hidden behind a kernel option (IPSTEALTH). Reviewed by: eivind, bde

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).

o Introduce "options REGRESSION", a kernel option which enables interfaces and functionality intended for use during correctness and regression testing. Features enabled by "options REGRESSION" may in and of themselves introduce security or correctness problems if used improperly, and so are not intended for use in production systems, only in testing environments.

REGRESSION opt_global.h
Add a new kernel option RESTARTABLE_PANICS. If this option is present, then one can restart from a panic by resetting the panicstr variable to NULL. This commit conditionalizes the previously committed functionality on this variable. It also removes the __dead2 attribute from the panic() function so that when one continues from a panic() the behavior will be predictable.

At the same time, make the "boot -a" prompt both more able and more informative.

KTR_VERBOSE opt_ktr.h
- 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().

Both numbers can be changed at compile time, the size of the overflow table also with the sysctl vfs.devfs.noverflow.

Mutex profiling code, conditional on the MUTEX_PROFILING option. Adds the following sysctl variables: debug.mutex.prof.enable enable / disable profiling debug.mutex.prof.acquisitions number of mutex acquisitions recorded debug.mutex.prof.records number of acquisition points recorded debug.mutex.prof.maxrecords max number of acquisition points debug.mutex.prof.rejected number of rejections (due to full table) debug.mutex.prof.hashsize hash size debug.mutex.prof.collisions number of hash collisions debug.mutex.prof.stats profiling statistics The code records four numbers for each acquisition point (identified by source file name and line number): longest time held, total time held, number of non-recursive acquisitions, average time held. The measurements are in clock cycles (as returned by get_cyclecount(9)); this may cause measurements on some SMP systems to be unreliable. This can probably be worked around by replacing get_cyclecount(9) by some incarnation of nanotime(9). This work was derived from initial patches by eivind.
