# Miscellaneous options.
Introduce support for adaptive spinning in lockmgr. Actually, as it did receive few tuning, the support is disabled by default, but it can opt-in with the option ADAPTIVE_LOCKMGRS. Due to the nature of lockmgrs, adaptive spinning needs to be selectively enabled for any interested lockmgr. The support is bi-directional, or, in other ways, it will work in both cases if the lock is held in read or write way. In particular, the read path is passible of further tunning using the sysctls debug.lockmgr.retries and debug.lockmgr.loops . Ideally, such sysctls should be axed or compiled out before release. Addictionally note that adaptive spinning doesn't cope well with LK_SLEEPFAIL. The reason is that many (and probabilly all) consumers of LK_SLEEPFAIL are mainly interested in knowing if the interlock was dropped or not in order to reacquire it and re-test initial conditions. This directly interacts with adaptive spinning because lockmgr needs to drop the interlock while spinning in order to avoid a deadlock (further details in the comments inside the patch). Final note: finding someone willing to help on tuning this with relevant workloads would be either very important and appreciated. Tested by: jeff, pho Requested by: many

- Make callout(9) tickless, relying on eventtimers(4) as backend for precise time event generation. This greatly improves granularity of callouts which are not anymore constrained to wait next tick to be scheduled. - Extend the callout KPI introducing a set of callout_reset_sbt* functions, which take a sbintime_t as timeout argument. The new KPI also offers a way for consumers to specify precision tolerance they allow, so that callout can coalesce events and reduce number of interrupts as well as potentially avoid scheduling a SWI thread. - Introduce support for dispatching callouts directly from hardware interrupt context, specifying an additional flag. This feature should be used carefully, as long as interrupt context has some limitations (e.g. no sleeping locks can be held). - Enhance mechanisms to gather informations about callwheel, introducing a new sysctl to obtain stats. This change breaks the KBI. struct callout fields has been changed, in particular 'int ticks' (4 bytes) has been replaced with 'sbintime_t' (8 bytes) and another 'sbintime_t' field was added for precision.

Import the CloudABI datatypes and create a system call table. CloudABI is a pure capability-based runtime environment for UNIX. It works similar to Capsicum, except that processes already run in capabilities mode on startup. All functionality that conflicts with this model has been omitted, making it a compact binary interface that can be supported by other operating systems without too much effort. CloudABI is 'secure by default'; the idea is that it should be safe to run arbitrary third-party binaries without requiring any explicit hardware virtualization (Bhyve) or namespace virtualization (Jails). The rights of an application are purely determined by the set of file descriptors that you grant it on startup. The datatypes and constants used by CloudABI's C library (cloudlibc) are defined in separate files called syscalldefs_mi.h (pointer size independent) and syscalldefs_md.h (pointer size dependent). We import these files in sys/contrib/cloudabi and wrap around them in cloudabi*_syscalldefs.h. We then add stubs for all of the system calls in sys/compat/cloudabi or sys/compat/cloudabi64, depending on whether the system call depends on the pointer size. We only have nine system calls that depend on the pointer size. If we ever want to support 32-bit binaries, we can simply add sys/compat/cloudabi32 and implement these nine system calls again. The next step is to send in code reviews for the individual system call implementations, but also add a sysentvec, to allow CloudABI executabled to be started through execve().

Introduce the new kernel thread called "deadlock resolver". While the name is pretentious, a good explanation of its targets is reported in this 17 months old presentation e-mail: http://lists.freebsd.org/pipermail/freebsd-arch/2008-August/008452.html In order to implement it, the sq_type in sleepqueues is mandatory and not only compiled along with INVARIANTS option. Additively, a new sleepqueue function, sleepq_type() is added, returning the type of the sleepqueue linked to a wchan. Three new sysctls are added in order to configure the thread: debug.deadlkres.slptime_threshold debug.deadlkres.blktime_threshold debug.deadlkres.sleepfreq rappresenting the thresholds for sleep and block time that will lead to a deadlock matching (when exceeded), while the sleepfreq rappresents the number of seconds between 2 consecutive thread runnings.

FULL_PREEMPTION opt_sched.h
Reimplement support for userland core dump compression using a new interface in kern_gzio.c. The old gzio interface was somewhat inflexible and has not worked properly since r272535: currently, the gzio functions are called with a range lock held on the output vnode, but kern_gzio.c does not pass the IO_RANGELOCKED flag to vn_rdwr() calls, resulting in deadlock when vn_rdwr() attempts to reacquire the range lock. Moreover, the new gzio interface can be used to implement kernel core compression. This change also modifies the kernel configuration options needed to enable userland core dump compression support: gzio is now an option rather than a device, and the COMPRESS_USER_CORES option is removed. Core dump compression is enabled using the kern.compress_user_cores sysctl/tunable. Differential Revision: https://reviews.freebsd.org/D1832 Reviewed by: rpaulo Discussed with: kib

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_ELI 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.

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!

MFgraid/head: Add new RAID GEOM class, that is going to replace ataraid(4) in supporting various BIOS-based software RAIDs. Unlike ataraid(4) this implementation does not depend on legacy ata(4) subsystem and can be used with any disk drivers, including new CAM-based ones (ahci(4), siis(4), mvs(4), ata(4) with `options ATA_CAM`). To make code more readable and extensible, this implementation follows modular design, including core part and two sets of modules, implementing support for different metadata formats and RAID levels. Support for such popular metadata formats is now implemented: Intel, JMicron, NVIDIA, Promise (also used by AMD/ATI) and SiliconImage. Such RAID levels are now supported: RAID0, RAID1, RAID1E, RAID10, SINGLE, CONCAT. For any all of these RAID levels and metadata formats this class supports full cycle of volume operations: reading, writing, creation, deletion, disk removal and insertion, rebuilding, dirty shutdown detection and resynchronization, bad sector recovery, faulty disks tracking, hot-spare disks. For Intel and Promise formats there is support multiple volumes per disk set. Look graid(8) manual page for additional details.

- For kernel compiled only with KDTRACE_HOOKS and not any lock debugging option, unbreak the lock tracing release semantic by embedding calls to LOCKSTAT_PROFILE_RELEASE_LOCK() direclty in the inlined version of the releasing functions for mutex, rwlock and sxlock. Failing to do so skips the lockstat_probe_func invokation for unlocking. - As part of the LOCKSTAT support is inlined in mutex operation, for kernel compiled without lock debugging options, potentially every consumer must be compiled including opt_kdtrace.h. Fix this by moving KDTRACE_HOOKS into opt_global.h and remove the dependency by opt_kdtrace.h for all files, as now only KDTRACE_FRAMES is linked there and it is only used as a compile-time stub [0]. [0] immediately shows some new bug as DTRACE-derived support for debug in sfxge is broken and it was never really tested. As it was not including correctly opt_kdtrace.h before it was never enabled so it was kept broken for a while.

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.

Reimplement how PCI-PCI bridges manage their I/O windows. Previously the driver would verify that requests for child devices were confined to any existing I/O windows, but the driver relied on the firmware to initialize the windows and would never grow the windows for new requests. Now the driver actively manages the I/O windows. This is implemented by allocating a bus resource for each I/O window from the parent PCI bus and suballocating that resource to child devices. The suballocations are managed by creating an rman for each I/O window. The suballocated resources are mapped by passing the bus_activate_resource() call up to the parent PCI bus. Windows are grown when needed by using bus_adjust_resource() to adjust the resource allocated from the parent PCI bus. If the adjust request succeeds, the window is adjusted and the suballocation request for the child device is retried. When growing a window, the rman_first_free_region() and rman_last_free_region() routines are used to determine if the front or end of the existing I/O window is free. From using that, the smallest ranges that need to be added to either the front or back of the window are computed. The driver will first try to grow the window in whichever direction requires the smallest growth first followed by the other direction if that fails. Subtractive bridges will first attempt to satisfy requests for child resources from I/O windows (including attempts to grow the windows). If that fails, the request is passed up to the parent PCI bus directly however. The PCI-PCI bridge driver will try to use firmware-assigned ranges for child BARs first and only allocate a "fresh" range if that specific range cannot be accommodated in the I/O window. This allows systems where the firmware assigns resources during boot but later wipes the I/O windows (some ACPI BIOSen are known to do this) to "rediscover" the original I/O window ranges. The ACPI Host-PCI bridge driver has been adjusted to correctly honor hw.acpi.host_mem_start and the I/O port equivalent when a PCI-PCI bridge makes a wildcard request for an I/O window range. The new PCI-PCI bridge driver is only enabled if the NEW_PCIB kernel option is enabled. This is a transition aide to allow platforms that do not yet support bus_activate_resource() and bus_adjust_resource() in their Host-PCI bridge drivers (and possibly other drivers as needed) to use the old driver for now. Once all platforms support the new driver, the kernel option and old driver will be removed. PR: kern/143874 kern/149306 Tested by: mav

The flag SX_ADAPTIVESPIN to be passed to sx_init_flags(9) gets suppressed and the new flag, offering the reversed logic, SX_NOADAPTIVE is added. Additively implements adaptive spininning for sx held in shared mode. The spinning limit can be handled through sysctls in order to be tuned while the code doesn't reach the release, after which time they should be dropped probabilly. This change has made been necessary by recent benchmarks where it does improve concurrency of workloads in presence of high contention (ie. ZFS). KPI breakage is documented by __FreeBSD_version bumping, manpage and UPDATING updates. Requested by: jeff, kmacy Reviewed by: jeff Tested by: pho

Implement interface to create SR-IOV Virtual Functions Implement the interace to create SR-IOV Virtual Functions (VFs). When a driver registers that they support SR-IOV by calling pci_setup_iov(), the SR-IOV code creates a new node in /dev/iov for that device. An ioctl can be invoked on that device to create VFs and have the driver initialize them. At this point, allocating memory I/O windows (BARs) is not supported.

Implement support for RPCSEC_GSS authentication to both the NFS client and server. This replaces the RPC implementation of the NFS client and server with the newer RPC implementation originally developed (actually ported from the userland sunrpc code) to support the NFS Lock Manager. I have tested this code extensively and I believe it is stable and that performance is at least equal to the legacy RPC implementation. The NFS code currently contains support for both the new RPC implementation and the older legacy implementation inherited from the original NFS codebase. The default is to use the new implementation - add the NFS_LEGACYRPC option to fall back to the old code. When I merge this support back to RELENG_7, I will probably change this so that users have to 'opt in' to get the new code. To use RPCSEC_GSS on either client or server, you must build a kernel which includes the KGSSAPI option and the crypto device. On the userland side, you must build at least a new libc, mountd, mount_nfs and gssd. You must install new versions of /etc/rc.d/gssd and /etc/rc.d/nfsd and add 'gssd_enable=YES' to /etc/rc.conf. As long as gssd is running, you should be able to mount an NFS filesystem from a server that requires RPCSEC_GSS authentication. The mount itself can happen without any kerberos credentials but all access to the filesystem will be denied unless the accessing user has a valid ticket file in the standard place (/tmp/krb5cc_<uid>). There is currently no support for situations where the ticket file is in a different place, such as when the user logged in via SSH and has delegated credentials from that login. This restriction is also present in Solaris and Linux. In theory, we could improve this in future, possibly using Brooks Davis' implementation of variant symlinks. Supporting RPCSEC_GSS on a server is nearly as simple. You must create service creds for the server in the form 'nfs/<fqdn>@<REALM>' and install them in /etc/krb5.keytab. The standard heimdal utility ktutil makes this fairly easy. After the service creds have been created, you can add a '-sec=krb5' option to /etc/exports and restart both mountd and nfsd. The only other difference an administrator should notice is that nfsd doesn't fork to create service threads any more. In normal operation, there will be two nfsd processes, one in userland waiting for TCP connections and one in the kernel handling requests. The latter process will create as many kthreads as required - these should be visible via 'top -H'. The code has some support for varying the number of service threads according to load but initially at least, nfsd uses a fixed number of threads according to the value supplied to its '-n' option.

NO_FFS_SNAPSHOT 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.

UFS_EXTATTR opt_ufs.h
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.

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

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.

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.

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.

Implement a CPU-affine TCP and UDP connection lookup data structure, struct inpcbgroup. pcbgroups, or "connection groups", supplement the existing inpcbinfo connection hash table, which when pcbgroups are enabled, might now be thought of more usefully as a per-protocol 4-tuple reservation table. Connections are assigned to connection groups base on a hash of their 4-tuple; wildcard sockets require special handling, and are members of all connection groups. During a connection lookup, a per-connection group lock is employed rather than the global pcbinfo lock. By aligning connection groups with input path processing, connection groups take on an effective CPU affinity, especially when aligned with RSS work placement (see a forthcoming commit for details). This eliminates cache line migration associated with global, protocol-layer data structures in steady state TCP and UDP processing (with the exception of protocol-layer statistics; further commit to follow). Elements of this approach were inspired by Willman, Rixner, and Cox's 2006 USENIX paper, "An Evaluation of Network Stack Parallelization Strategies in Modern Operating Systems". However, there are also significant differences: we maintain the inpcb lock, rather than using the connection group lock for per-connection state. Likewise, the focus of this implementation is alignment with NIC packet distribution strategies such as RSS, rather than pure software strategies. Despite that focus, software distribution is supported through the parallel netisr implementation, and works well in configurations where the number of hardware threads is greater than the number of NIC input queues, such as in the RMI XLR threaded MIPS architecture. Another important difference is the continued maintenance of existing hash tables as "reservation tables" -- these are useful both to distinguish the resource allocation aspect of protocol name management and the more common-case lookup aspect. In configurations where connection tables are aligned with hardware hashes, it is desirable to use the traditional lookup tables for loopback or encapsulated traffic rather than take the expense of hardware hashes that are hard to implement efficiently in software (such as RSS Toeplitz). Connection group support is enabled by compiling "options PCBGROUP" into your kernel configuration; for the time being, this is an experimental feature, and hence is not enabled by default. Subject to the limited MFCability of change dependencies in inpcb, and its change to the inpcbinfo init function signature, this change in principle could be merged to FreeBSD 8.x.

PF_DEFAULT_TO_DROP opt_pf.h
This patch provides the back end support for equal-cost multi-path (ECMP) for both IPv4 and IPv6. Previously, multipath route insertion is disallowed. For example, route add -net 192.103.54.0/24 10.9.44.1 route add -net 192.103.54.0/24 10.9.44.2 The second route insertion will trigger an error message of "add net 192.103.54.0/24: gateway 10.2.5.2: route already in table" Multiple default routes can also be inserted. Here is the netstat output: default 10.2.5.1 UGS 0 3074 bge0 => default 10.2.5.2 UGS 0 0 bge0 When multipath routes exist, the "route delete" command requires a specific gateway to be specified or else an error message would be displayed. For example, route delete default would fail and trigger the following error message: "route: writing to routing socket: No such process" "delete net default: not in table" On the other hand, route delete default 10.2.5.2 would be successful: "delete net default: gateway 10.2.5.2" One does not have to specify a gateway if there is only a single route for a particular destination. I need to perform more testings on address aliases and multiple interfaces that have the same IP prefixes. This patch as it stands today is not yet ready for prime time. Therefore, the ECMP code fragments are fully guarded by the RADIX_MPATH macro. Include the "options RADIX_MPATH" in the kernel configuration to enable this feature.

ROUTETABLES opt_route.h
Several years after initial development, merge prototype support for linking NIC Receive Side Scaling (RSS) to the network stack's connection-group implementation. This prototype (and derived patches) are in use at Juniper and several other FreeBSD-using companies, so despite some reservations about its maturity, merge the patch to the base tree so that it can be iteratively refined in collaboration rather than maintained as a set of gradually diverging patch sets. (1) Merge a software implementation of the Toeplitz hash specified in RSS implemented by David Malone. This is used to allow suitable pcbgroup placement of connections before the first packet is received from the NIC. Software hashing is generally avoided, however, due to high cost of the hash on general-purpose CPUs. (2) In in_rss.c, maintain authoritative versions of RSS state intended to be pushed to each NIC, including keying material, hash algorithm/ configuration, and buckets. Provide software-facing interfaces to hash 2- and 4-tuples for IPv4 and IPv6 using both the RSS standardised Toeplitz and a 'naive' variation with a hash efficient in software but with poor distribution properties. Implement rss_m2cpuid()to be used by netisr and other load balancing code to look up the CPU on which an mbuf should be processed. (3) In the Ethernet link layer, allow netisr distribution using RSS as a source of policy as an alternative to source ordering; continue to default to direct dispatch (i.e., don't try and requeue packets for processing on the 'right' CPU if they arrive in a directly dispatchable context). (4) Allow RSS to control tuning of connection groups in order to align groups with RSS buckets. If a packet arrives on a protocol using connection groups, and contains a suitable hardware-generated hash, use that hash value to select the connection group for pcb lookup for both IPv4 and IPv6. If no hardware-generated Toeplitz hash is available, we fall back on regular PCB lookup risking contention rather than pay the cost of Toeplitz in software -- this is a less scalable but, at my last measurement, faster approach. As core counts go up, we may want to revise this strategy despite CPU overhead. Where device drivers suitably configure NICs, and connection groups / RSS are enabled, this should avoid both lock and line contention during connection lookup for TCP. This commit does not modify any device drivers to tune device RSS configuration to the global RSS configuration; patches are in circulation to do this for at least Chelsio T3 and Intel 1G/10G drivers. Currently, the KPI for device drivers is not particularly robust, nor aware of more advanced features such as runtime reconfiguration/rebalancing. This will hopefully prove a useful starting point for refinement. No MFC is scheduled as we will first want to nail down a more mature and maintainable KPI/KBI for device drivers.

TCP_OFFLOAD opt_inet.h # Enable code to dispatch TCP offloading
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

TCP_SIGNATURE opt_inet.h
Merge the //depot/user/yar/vlan branch into CVS. It contains some collective work by yar, thompsa and myself. The checksum offloading part also involves work done by Mihail Balikov. The most important changes: o Instead of global linked list of all vlan softc use a per-trunk hash. The size of hash is dynamically adjusted, depending on number of entries. This changes struct ifnet, replacing counter of vlans with a pointer to trunk structure. This change is an improvement for setups with big number of VLANs, several interfaces and several CPUs. It is a small regression for a setup with a single VLAN interface. An alternative to dynamic hash is a per-trunk static array with 4096 entries, which is a compile time option - VLAN_ARRAY. In my experiments the array is not an improvement, probably because such a big trunk structure doesn't fit into CPU cache. o Introduce an UMA zone for VLAN tags. Since drivers depend on it, the zone is declared in kern_mbuf.c, not in optional vlan(4) driver. This change is a big improvement for any setup utilizing vlan(4). o Use rwlock(9) instead of mutex(9) for locking. We are the first ones to do this! :) o Some drivers can do hardware VLAN tagging + hardware checksum offloading. Add an infrastructure for this. Whenever vlan(4) is attached to a parent or parent configuration is changed, the flags on vlan(4) interface are updated.

Retire 'options TI_PRIVATE_JUMBOS' and replace local jumbo allocator with UMA backed jumbo allocator by default. Previously ti(4) used sf_buf(9) interface for jumbo buffers but it was broken at this moment such that enabling jumbo frame caused instant panic. Due to the nature of sf_buf(9) it heavily relies on VM changes but it seems ti(4) was not received much blessing from VM gurus. I don't understand VM magic and implications used in driver either. Switching to UMA backed jumbo allocator like other network drivers will make jumbo frame work on ti(4). While I'm here, fully allocate all RX buffers. This means ti(4) now uses 512 RX buffer and 1024 mini RX buffers. To use sf_buf(9) interface for jumbo buffers, introduce a new 'options TI_SF_BUF_JUMBO'. If it is proven that sf_buf(9) is better for jumbo buffers, interesting developers can fix the issue in future. ti(4) still needs more bus_dma(9) cleanups and should use separate DMA tag/map for each ring(standard, jumbo, mini, command, event etc) but it should work on all platforms except PAE. Special thanks to Jay[1] who provided complete remote debugging access. Tested by: Jay Borkenhagen <jayb <> braeburn dot org > [1]

TI_SF_BUF_JUMBO opt_ti.h
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.

MUTEX_PROFILING has been generalized to LOCK_PROFILING. We now profile wait (time waited to acquire) and hold times for *all* kernel locks.

Large chunks of profiling code have been moved out of line, the overhead measured on the T1 for when it is compiled in but not enabled is < 1%.

Further improvements to LOCK_PROFILING: - Fix missing initialization in kern_rwlock.c causing bogus times to be collected - Move updates to the lock hash to after the lock is released for spin mutexes, sleep mutexes, and sx locks - Add new kernel build option LOCK_PROFILE_FAST - only update lock profiling statistics when an acquisition is contended. This reduces the overhead of LOCK_PROFILING to increasing system time by 20%-25% which on "make -j8 kernel-toolchain" on a dual woodcrest is unmeasurable in terms of wall-clock time. Contrast this to enabling lock profiling without LOCK_PROFILE_FAST and I see a 5x-6x slowdown in wall-clock time.

This implementation is by no means perfect as far as some of the algorithms that it uses and the fact that it is missing some functionality (try locks and upgrades/downgrades are not there yet), however it does seem to work in my local testing. There is more detail in the comments in the code, but the short version follows. A reader/writer lock is very much like a regular mutex: it cannot be held across a voluntary sleep; it can be acquired in an interrupt thread; if the lock is held by a writer then the priority of any threads that block on the lock will be lent to the owner; the simple case lock operations all are done in a single atomic op. It also shares some similiarities with sx locks: it supports reader/writer semantics (multiple readers, but single writers); readers are allowed to recurse, but writers are not. We can extend this implementation further by either improving algorithms or adding new functionality, but this should at least give us a base to work with now. Reviewed by: arch (in theory) Tested on: i386 (4 cpu box with a kernel module that used 4 threads that randomly chose between read locks and write locks that ran w/o panicing for over a day solid. It usually panic'd within a few seconds when there were bugs during testing. :) The kernel module source is available on request.)

RWLOCK_NOINLINE opt_global.h
Optimize sx locks to use simple atomic operations for the common cases of obtaining and releasing shared and exclusive locks. The algorithms for manipulating the lock cookie are very similar to that rwlocks. This patch also adds support for exclusive locks using the same algorithm as mutexes. A new sx_init_flags() function has been added so that optional flags can be specified to alter a given locks behavior. The flags include SX_DUPOK, SX_NOWITNESS, SX_NOPROFILE, and SX_QUITE which are all identical in nature to the similar flags for mutexes. Adaptive spinning on select locks may be enabled by enabling the ADAPTIVE_SX kernel option. Only locks initialized with the SX_ADAPTIVESPIN flag via sx_init_flags() will adaptively spin. The common cases for sx_slock(), sx_sunlock(), sx_xlock(), and sx_xunlock() are now performed inline in non-debug kernels. As a result, <sys/sx.h> now requires <sys/lock.h> to be included prior to <sys/sx.h>. The new kernel option SX_NOINLINE can be used to disable the aforementioned inlining in non-debug kernels. The size of struct sx has changed, so the kernel ABI is probably greatly disturbed. MFC after: 1 month Submitted by: attilio Tested by: kris, pjd

NO_SWAPPING opt_vm.h
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

MALLOC_PROFILE opt_vm.h
Add MALLOC_DEBUG_MAXZONES debug malloc(9) option to use multiple uma zones for each malloc bucket size. The purpose is to isolate different malloc types into hash classes, so that any buffer overruns or use-after-free will usually only affect memory from malloc types in that hash class. This is purely a debugging tool; by varying the hash function and tracking which hash class was corrupted, the intersection of the hash classes from each instance will point to a single malloc type that is being misused. At this point inspection or memguard(9) can be used to catch the offending code. Add MALLOC_DEBUG_MAXZONES=8 to -current GENERIC configuration files. The suggestion to have this on by default came from Kostik Belousov on -arch. This code is based on work by Ron Steinke at Isilon Systems.

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.

ACPI_DEBUG opt_acpi.h
Catch up with r193750 (OsdSynch.c locking changes): - Preallocate some memory for ACPI tasks early enough. We cannot use malloc(9) any more because spin mutex may be held here. The reserved memory can be tuned via debug.acpi.max_tasks tunable or ACPI_MAX_TASKS in kernel configuration. The default is 32 tasks. - Implement a custom taskqueue_fast to wrap the new memory allocation. This implementation is not the fastest in the world but we are being conservative here.

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_MAX_THREADS opt_acpi.h
Import the driver for VT-d DMAR hardware, as specified in the revision 1.3 of Intelб╝ Virtualization Technology for Directed I/O Architecture Specification. The Extended Context and PASIDs from the rev. 2.2 are not supported, but I am not aware of any released hardware which implements them. Code does not use queued invalidation, see comments for the reason, and does not provide interrupt remapping services. Code implements the management of the guest address space per domain and allows to establish and tear down arbitrary mappings, but not partial unmapping. The superpages are created as needed, but not promoted. Faults are recorded, fault records could be obtained programmatically, and printed on the console. Implement the busdma(9) using DMARs. This busdma backend avoids bouncing and provides security against misbehaving hardware and driver bad programming, preventing leaks and corruption of the memory by wild DMA accesses. By default, the implementation is compiled into amd64 GENERIC kernel but disabled; to enable, set hw.dmar.enable=1 loader tunable. Code is written to work on i386, but testing there was low priority, and driver is not enabled in GENERIC. Even with the DMAR turned on, individual devices could be directed to use the bounce busdma with the hw.busdma.pci<domain>:<bus>:<device>:<function>.bounce=1 tunable. If DMARs are capable of the pass-through translations, it is used, otherwise, an identity-mapping page table is constructed. The driver was tested on Xeon 5400/5500 chipset legacy machine, Haswell desktop and E5 SandyBridge dual-socket boxes, with ahci(4), ata(4), bce(4), ehci(4), mfi(4), uhci(4), xhci(4) devices. It also works with em(4) and igb(4), but there some fixes are needed for drivers, which are not committed yet. Intel GPUs do not work with DMAR (yet). Many thanks to John Baldwin, who explained me the newbus integration; Peter Holm, who did all testing and helped me to discover and understand several incredible bugs; and to Jim Harris for the access to the EDS and BWG and for listening when I have to explain my findings to somebody.

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.

# ed driver
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.

# teken terminal emulator options
Switch the default terminal emulation style to xterm for most platforms. Right now syscons(4) uses a cons25-style terminal emulator. The disadvantages of that are: - Little compatibility with embedded devices with serial interfaces. - Bad bandwidth efficiency, mainly because of the lack of scrolling regions. - A very hard transition path to support for modern character sets like UTF-8. Our terminal emulation library, libteken, has been supporting xterm-style terminal emulation for months, so flip the switch and make everyone use an xterm-style console driver. I still have to enable this on i386. Right now pc98 and i386 share the same /etc/ttys file. I'm not going to switch pc98, because it uses its own Kanji-capable cons25 emulator. IMPORTANT: What to do if things go wrong (i.e. graphical artifacts): - Run the application inside script(1), try to reduce the problem and send me the log file. - In the mean time, you can run `vidcontrol -T cons25' and `export TERM=cons25' so you can run applications the same way you did before. You can also build your kernel with `options TEKEN_CONS25' to make all virtual terminals use the cons25 emulator by default. Discussed on: current@

Note on the naming: Although affecting the output of vt(4), technically kern/subr_terminal.c is primarily concerned with changing default colors so it would be inconsistent to term these options VT_{KERN,NORM}_ATTR.

Turn console printf buffering into a kernel option and only on by default for sun4v where it is absolutely required. This change moves the buffer from struct pcpu to the stack to avoid using the critical section which created a LOR in a couple of cases due to interaction with the tty code and kqueue. The LOR can't be fixed with the critical section and the pcpu buffer can't be used without the critical section. Putting the buffer on the stack was my initial solution, but it was pointed out that the stress on the stack might cause problems depending on the call path. We don't have a way of creating tests for those possible cases, so it's best to leave this as an option for the time being. In time we may get enough data to enable this option more generally.

This is primarily to allow me to do some userland PHY error processing for radar and spectral scan data. However since EVM and per-chain RSSI is provided, others may find it useful for a variety of tasks. The default is to not compile in the radiotap vendor extensions, primarily because tcpdump doesn't seem to handle the particular vendor extension layout I'm using, and I'd rather not break existing code out there that may be (badly) parsing the radiotap data.

Overhaul regulatory support: o remove HAL_CHANNEL; convert the hal to use net80211 channels; this mostly involves mechanical changes to variable names and channel attribute macros o gut HAL_CHANNEL_PRIVATE as most of the contents are now redundant with the net80211 channel available o change api for ath_hal_init_channels: no more reglass id's, no more outdoor indication (was a noop), anM contents o add ath_hal_getchannels to have the hal construct a channel list without altering runtime state; this is used to retrieve the calibration list for the device in ath_getradiocaps o add ath_hal_set_channels to take a channel list and regulatory data from above and construct internal state to match (maps frequencies for 900MHz cards, setup for CTL lookups, etc) o compact the private channel table: we keep one private channel per frequency instead of one per HAL_CHANNEL; this gives a big space savings and potentially improves ani and calibration by sharing state (to be seen; didn't see anything in testing); a new config option AH_MAXCHAN controls the table size (default to 96 which was chosen to be ~3x the largest expected size) o shrink ani state and change to mirror private channel table (one entry per frequency indexed by ic_devdata) o move ani state flags to private channel state o remove country codes; use net80211 definitions instead o remove GSM regulatory support; it's no longer needed now that we pass in channel lists from above o consolidate ADHOC_NO_11A attribute with DISALLOW_ADHOC_11A o simplify initial channel list construction based on the EEPROM contents; we preserve country code support for now but may want to just fallback to a WWR sku and dispatch the discovered country code up to user space so the channel list can be constructed using the master regdomain tables o defer to net80211 for max antenna gain o eliminate sorting of internal channel table; now that we use ic_devdata as an index, table lookups are O(1) o remove internal copy of the country code; the public one is sufficient o remove AH_SUPPORT_11D conditional compilation; we always support 11d o remove ath_hal_ispublicsafetysku; not needed any more o remove ath_hal_isgsmsku; no more GSM stuff o move Conformance Test Limit (CTL) state from private channel to a lookup using per-band pointers cached in the private state block o remove regulatory class id support; was unused and belongs in net80211 o fix channel list construction to set IEEE80211_CHAN_NOADHOC, IEEE80211_CHAN_NOHOSTAP, and IEEE80211_CHAN_4MSXMIT o remove private channel flags CHANNEL_DFS and CHANNEL_4MS_LIMIT; these are now set in the constructed net80211 channel o store CHANNEL_NFCREQUIRED (Noise Floor Required) channel attribute in one of the driver-private flag bits of the net80211 channel o move 900MHz frequency mapping into the hal; the mapped frequency is stored in the private channel and used throughout the hal (no more mapping in the driver and/or net80211) o remove ath_hal_mhz2ieee; it's no longer needed as net80211 does the calculation and available in the net80211 channel o change noise floor calibration logic to work with compacted private channel table setup; this may require revisiting as we no longer can distinguish channel attributes (e.g. 11b vs 11g vs turbo) but since the data is used only to calculate status data we can live with it for now o change ah_getChipPowerLimits internal method to operate on a single channel instead of all channels in the private channel table o add ath_hal_gethwchannel to map a net80211 channel to a h/w frequency (always the same except for 900MHz channels) o add HAL_EEBADREG and HAL_EEBADCC status codes to better identify regulatory problems o remove CTRY_DEBUG and CTRY_DEFAULT enum's; these come from net80211 now o change ath_hal_getwirelessmodes to really return wireless modes supported by the hardware (was previously applying regulatory constraints) o return channel interference status with IEEE80211_CHANSTATE_CWINT (should change to a callback so hal api's can take const pointers) o remove some #define's no longer needed with the inclusion of <net80211/_ieee80211.h> Sponsored by: Carlson Wireless

The Atheros AR71xx CPUs, when paired with the AR5212 parts, has a bug that generates a fatal bus trap. Normally, the chips are setup to do 128 byte DMA bursts, but when on this CPU, they can only safely due 4-byte DMA bursts due to this bug. Details of the exact nature of the bug are sketchy, but some can be found at https://forum.openwrt.org/viewtopic.php?pid=70060 on pages 4, 5 and 6. There's a small performance penalty associated with this workaround, so it is only enabled when needed on the Atheros AR71xx platforms. Unfortunately, this condition is impossible to detect at runtime without MIPS specific ifdefs. Rather than cast an overly-broad net like Linux/OpenWRT dues (which enables this workaround all the time on MIPS32 platforms), we put this option in the kernel for just the affected machines. Sam didn't like this aspect of the patch when he reviewed it, and I'd love to hear sane proposals on how to fix it :) Reviewed by: sam@

IEEE80211_AMPDU_AGE opt_wlan.h
Implementation of the upcoming Wireless Mesh standard, 802.11s, on the net80211 wireless stack. This work is based on the March 2009 D3.0 draft standard. This standard is expected to become final next year. This includes two main net80211 modules, ieee80211_mesh.c which deals with peer link management, link metric calculation, routing table control and mesh configuration and ieee80211_hwmp.c which deals with the actually routing process on the mesh network. HWMP is the mandatory routing protocol on by the mesh standard, but others, such as RA-OLSR, can be implemented. Authentication and encryption are not implemented. There are several scripts under tools/tools/net80211/scripts that can be used to test different mesh network topologies and they also teach you how to setup a mesh vap (for the impatient: ifconfig wlan0 create wlandev ... wlanmode mesh). A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled by default on GENERIC kernels for i386, amd64, sparc64 and pc98. Drivers that support mesh networks right now are: ath, ral and mwl. More information at: http://wiki.freebsd.org/WifiMesh Please note that this work is experimental. Also, please note that bridging a mesh vap with another network interface is not yet supported. Many thanks to the FreeBSD Foundation for sponsoring this project and to Sam Leffler for his support. Also, I would like to thank Gateworks Corporation for sending me a Cambria board which was used during the development of this project.

Sound Mega-commit. Expect further cleanup until code freeze. For a slightly thorough explaination, please refer to [1] http://people.freebsd.org/~ariff/SOUND_4.TXT.html . Summary of changes includes: 1 Volume Per-Channel (vpc). Provides private / standalone volume control unique per-stream pcm channel without touching master volume / pcm. Applications can directly use SNDCTL_DSP_[GET|SET][PLAY|REC]VOL, or for backwards compatibility, SOUND_MIXER_PCM through the opened dsp device instead of /dev/mixer. Special "bypass" mode is enabled through /dev/mixer which will automatically detect if the adjustment is made through /dev/mixer and forward its request to this private volume controller. Changes to this volume object will not interfere with other channels. Requirements: - SNDCTL_DSP_[GET|SET][PLAY|REC]_VOL are newer ioctls (OSSv4) which require specific application modifications (preferred). - No modifications required for using bypass mode, so applications like mplayer or xmms should work out of the box. Kernel hints: - hint.pcm.%d.vpc (0 = disable vpc). Kernel sysctls: - hw.snd.vpc_mixer_bypass (default: 1). Enable or disable /dev/mixer bypass mode. - hw.snd.vpc_autoreset (default: 1). By default, closing/opening /dev/dsp will reset the volume back to 0 db gain/attenuation. Setting this to 0 will preserve its settings across device closing/opening. - hw.snd.vpc_reset (default: 0). Panic/reset button to reset all volume settings back to 0 db. - hw.snd.vpc_0db (default: 45). 0 db relative to linear mixer value. 2 High quality fixed-point Bandlimited SINC sampling rate converter, based on Julius O'Smith's Digital Audio Resampling - http://ccrma.stanford.edu/~jos/resample/. It includes a filter design script written in awk (the clumsiest joke I've ever written) - 100% 32bit fixed-point, 64bit accumulator. - Possibly among the fastest (if not fastest) of its kind. - Resampling quality is tunable, either runtime or during kernel compilation (FEEDER_RATE_PRESETS). - Quality can be further customized during kernel compilation by defining FEEDER_RATE_PRESETS in /etc/make.conf. Kernel sysctls: - hw.snd.feeder_rate_quality. 0 - Zero-order Hold (ZOH). Fastest, bad quality. 1 - Linear Interpolation (LINEAR). Slightly slower than ZOH, better quality but still does not eliminate aliasing. 2 - (and above) - Sinc Interpolation(SINC). Best quality. SINC quality always start from 2 and above. Rough quality comparisons: - http://people.freebsd.org/~ariff/z_comparison/ 3 Bit-perfect mode. Bypasses all feeder/dsp effects. Pure sound will be directly fed into the hardware. 4 Parametric (compile time) Software Equalizer (Bass/Treble mixer). Can be customized by defining FEEDER_EQ_PRESETS in /etc/make.conf. 5 Transparent/Adaptive Virtual Channel. Now you don't have to disable vchans in order to make digital format pass through. It also makes vchans more dynamic by choosing a better format/rate among all the concurrent streams, which means that dev.pcm.X.play.vchanformat/rate becomes sort of optional. 6 Exclusive Stream, with special open() mode O_EXCL. This will "mute" other concurrent vchan streams and only allow a single channel with O_EXCL set to keep producing sound. Other Changes: * most feeder_* stuffs are compilable in userland. Let's not speculate whether we should go all out for it (save that for FreeBSD 16.0-RELEASE). * kobj signature fixups, thanks to Andriy Gapon <avg@freebsd.org> * pull out channel mixing logic out of vchan.c and create its own feeder_mixer for world justice. * various refactoring here and there, for good or bad. * activation of few more OSSv4 ioctls() (see [1] above). * opt_snd.h for possible compile time configuration: (mostly for debugging purposes, don't try these at home) SND_DEBUG SND_DIAGNOSTIC SND_FEEDER_MULTIFORMAT SND_FEEDER_FULL_MULTIFORMAT SND_FEEDER_RATE_HP SND_PCM_64 SND_OLDSTEREO Manual page updates are on the way.

Add an option - AR71XX_REALMEM - which overrides the amount of memory detected from Redboot, or overrides the "otherwise" case if no Redboot information was found. Some AR71XX platforms don't use Redboot (eg TP-LINK devices using UBoot; some later Ubiquiti devices which apparently also use UBoot) and at least one plain out lies - the Ubiquiti LS-SR71A Redboot says there's 16mb of RAM when in fact there's 32mb. A more "clean" solution will be needed at a later date.

Add racct. It's an API to keep per-process, per-jail, per-loginclass and per-loginclass resource accounting information, to be used by the new resource limits code. It's connected to the build, but the code that actually calls the new functions will come later. Sponsored by: The FreeBSD Foundation Reviewed by: kib (earlier version)

Add YARROW_RNG and FORTUNA_RNG to sys/conf/options. Add a SYSINIT that forces a reseed during proc0 setup, which happens fairly late in the boot process. Add a RANDOM_DEBUG option which enables some debugging printf()s. Add a new RANDOM_ATTACH entropy source which harvests entropy from the get_cyclecount() delta across each call to a device attach method.

Change EM_MULTIQUEUE to a real kernconf entry and enable support for up to 2 rx/tx queues for the 82574. Program the 82574 to enable 5 msix vectors, assign 1 to each rx queue, 1 to each tx queue and 1 to the link handler. Inspired by DragonFlyBSD, enable some RSS logic for handling tx queue handling/processing. Move multiqueue handler functions so that they line up better in a diff review to if_igb.c Always enqueue tx work to be done in em_mq_start, if unable to acquire the TX lock, then this will be processed in the background later by the taskqueue. Remove mbuf argument from em_start_mq_locked() as the work is always enqueued. (stolen from igb) Setup TARC, TXDCTL and RXDCTL registers for better performance and stability in multiqueue and singlequeue implementations. Handle Intel errata 3 and generic multiqueue behavior with the initialization of TARC(0) and TARC(1) Bind interrupt threads to cpus in order. (stolen from igb) Add 2 new DDB functions, one to display the queue(s) and their settings and one to reset the adapter. Primarily used for debugging. In the multiqueue configuration, bump RXD and TXD ring size to max for the adapter (4096). Setup an RDTR of 64 and an RADV of 128 in multiqueue configuration to cut down on the number of interrupts. RADV was arbitrarily set to 2x RDTR and can be adjusted as needed. Cleanup the display in top a bit to make it clearer where the taskqueue threads are running and what they should be doing. Ensure that both queues are processed by em_local_timer() by writing them both to the IMS register to generate soft interrupts. Ensure that an soft interrupt is generated when em_msix_link() is run so that any races between assertion of the link/status interrupt and a rx/tx interrupt are handled. Document existing tuneables: hw.em.eee_setting, hw.em.msix, hw.em.smart_pwr_down, hw.em.sbp Document use of hw.em.num_queues and the new kernel option EM_MULTIQUEUE Thanks to Intel for their continued support of FreeBSD.
