- 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.

tcp: Congestion control cleanup. NOTE: HEADS UP read the note below if your kernel config is not including GENERIC!! This patch does a bit of cleanup on TCP congestion control modules. There were some rather interesting surprises that one could get i.e. where you use a socket option to change from one CC (say cc_cubic) to another CC (say cc_vegas) and you could in theory get a memory failure and end up on cc_newreno. This is not what one would expect. The new code fixes this by requiring a cc_data_sz() function so we can malloc with M_WAITOK and pass in to the init function preallocated memory. The CC init is expected in this case *not* to fail but if it does and a module does break the "no fail with memory given" contract we do fall back to the CC that was in place at the time. This also fixes up a set of common newreno utilities that can be shared amongst other CC modules instead of the other CC modules reaching into newreno and executing what they think is a "common and understood" function. Lets put these functions in cc.c and that way we have a common place that is easily findable by future developers or bug fixers. This also allows newreno to evolve and grow support for its features i.e. ABE and HYSTART++ without having to dance through hoops for other CC modules, instead both newreno and the other modules just call into the common functions if they desire that behavior or roll there own if that makes more sense. Note: This commit changes the kernel configuration!! If you are not using GENERIC in some form you must add a CC module option (one of CC_NEWRENO, CC_VEGAS, CC_CUBIC, CC_CDG, CC_CHD, CC_DCTCP, CC_HTCP, CC_HD). You can have more than one defined as well if you desire. Note that if you create a kernel configuration that does not define a congestion control module and includes INET or INET6 the kernel compile will break. Also you need to define a default, generic adds 'options CC_DEFAULT=\"newreno\" but you can specify any string that represents the name of the CC module (same names that show up in the CC module list under net.inet.tcp.cc). If you fail to add the options CC_DEFAULT in your kernel configuration the kernel build will also break. Reviewed by: Michael Tuexen Sponsored by: Netflix Inc.

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.

DEADLKRES opt_watchdog.h
Introduce an EXPERIMENTAL option for both src.conf(5) and the kernel. In the last decade(s) we have seen both short term or long term projects committed to the tree which were considered or even marked "experimental". While out-of-tree development has become easier than it used to be in CVS times, there still is a need to have the code shipping with HEAD but not enabled by default. While people may think about VIMAGE as one of the recent larger, long term projects, early protocol implementations (before they are standardised) are others. (Free)BSD historically was one of the operating systems which would have running code at early stages and help develop and influence standardisation and the industry. Give developers an opportunity to be more pro-active for early adoption or running large scale code changes stumbling over each others but not the user's feet. I have not added the option to NOTES in order to avoid breaking supported option builds, which require constant compile testing. Discussed with: people in the corridor

Core structure and functions to support a feed-forward clock within the kernel. Implement ffcounter, a monotonically increasing cumulative counter on top of the active timecounter. Provide low-level functions to read the ffcounter and convert it to absolute time or a time interval in seconds using the current ffclock estimates, which track the drift of the oscillator. Add a ring of fftimehands to track passing of time on each kernel tick and pick up updates of ffclock estimates. Committed on behalf of Julien Ridoux and Darryl Veitch from the University of Melbourne, Australia, as part of the FreeBSD Foundation funded "Feed-Forward Clock Synchronization Algorithms" project.

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

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.

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.

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.

mac: add new mac_ddb(4) policy Generally, access to the kernel debugger is considered to be unsafe from a security perspective since it presents an unrestricted interface to inspect or modify the system state, including sensitive data such as signing keys. However, having some access to debugger functionality on production systems may be useful in determining the cause of a panic or hang. Therefore, it is desirable to have an optional policy which allows limited use of ddb(4) while disabling the functionality which could reveal system secrets. This loadable MAC module allows for the use of some ddb(4) commands while preventing the execution of others. The commands have been broadly grouped into three categories: - Those which are 'safe' and will not emit sensitive data (e.g. trace). Generally, these commands are deterministic and don't accept arguments. - Those which are definitively unsafe (e.g. examine <addr>, search <addr> <value>) - Commands which may be safe to execute depending on the arguments provided (e.g. show thread <addr>). Safe commands have been flagged as such with the DB_CMD_MEMSAFE flag. Commands requiring extra validation can provide a function to do so. For example, 'show thread <addr>' can be used as long as addr can be checked against the system's list of process structures. The policy also prevents debugger backends other than ddb(4) from executing, for example gdb(4). Reviewed by: markj, pauamma_gundo.com (manpages) Sponsored by: Juniper Networks, Inc.

Make it possible to run ntpd as a non-root user, add ntpd uid and gid. Code analysis and runtime analysis using truss(8) indicate that the only privileged operations performed by ntpd are adjusting system time, and (re-)binding to privileged UDP port 123. These changes add a new mac(4) policy module, mac_ntpd(4), which grants just those privileges to any process running with uid 123. This also adds a new user and group, ntpd:ntpd, (uid:gid 123:123), and makes them the owner of the /var/db/ntp directory, so that it can be used as a location where the non-privileged daemon can write files such as the driftfile, and any optional logfile or stats files. Because there are so many ways to configure ntpd, the question of how to configure it to run without root privs can be a bit complex, so that will be addressed in a separate commit. These changes are just what's required to grant the limited subset of privs to ntpd, and the small change to ntpd to prevent it from exiting with an error if running as non-root.

This works on i386. It should work on amd64 but not well tested yet. StoreLib may or may not work. Remember to kldload mfi_linux. - Add in AEN (Async Event Notification) support so we can get messages from the firmware when something happens. Not all messages are in defined in event detail. Use event_log to try to figure out what happened. - Try to implement something like SIGIO for StoreLib. Since mrmonitor doesn't work right I can't fully test it. StoreLib works best with the rh9 base. In theory mrmonitor isn't needed due to native driver support of AEN :-) Now we can configure and monitor the RAID better. Submitted by: IronPort Systems.

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

Allocate pager bufs from UMA instead of 80-ish mutex protected linked list. o In vm_pager_bufferinit() create pbuf_zone and start accounting on how many pbufs are we going to have set. In various subsystems that are going to utilize pbufs create private zones via call to pbuf_zsecond_create(). The latter calls uma_zsecond_create(), and sets a limit on created zone. After startup preallocate pbufs according to requirements of all pbuf zones. Subsystems that used to have a private limit with old allocator now have private pbuf zones: md(4), fusefs, NFS client, smbfs, VFS cluster, FFS, swap, vnode pager. The following subsystems use shared pbuf zone: cam(4), nvme(4), physio(9), aio(4). They should have their private limits, but changing that is out of scope of this commit. o Fetch tunable value of kern.nswbuf from init_param2() and while here move NSWBUF_MIN to opt_param.h and eliminate opt_swap.h, that was holding only this option. Default values aren't touched by this commit, but they probably should be reviewed wrt to modern hardware. This change removes a tight bottleneck from sendfile(2) operation, that uses pbufs in vnode pager. Other pagers also would benefit from faster allocation. Together with: gallatin Tested by: pho

Native PCI-express HotPlug support. PCI-express HotPlug support is implemented via bits in the slot registers of the PCI-express capability of the downstream port along with an interrupt that triggers when bits in the slot status register change. This is implemented for FreeBSD by adding HotPlug support to the PCI-PCI bridge driver which attaches to the virtual PCI-PCI bridges representing downstream ports on HotPlug slots. The PCI-PCI bridge driver registers an interrupt handler to receive HotPlug events. It also uses the slot registers to determine the current HotPlug state and drive an internal HotPlug state machine. For simplicty of implementation, the PCI-PCI bridge device detaches and deletes the child PCI device when a card is removed from a slot and creates and attaches a PCI child device when a card is inserted into the slot. The PCI-PCI bridge driver provides a bus_child_present which claims that child devices are present on HotPlug-capable slots only when a card is inserted. Rather than requiring a timeout in the RC for config accesses to not-present children, the pcib_read/write_config methods fail all requests when a card is not present (or not yet ready). These changes include support for various optional HotPlug capabilities such as a power controller, mechanical latch, electro-mechanical interlock, indicators, and an attention button. It also includes support for devices which require waiting for command completion events before initiating a subsequent HotPlug command. However, it has only been tested on ExpressCard systems which support surprise removal and have none of these optional capabilities. PCI-express HotPlug support is conditional on the PCI_HP option which is enabled by default on arm64, x86, and powerpc.

TCPHPTS opt_inet.h
Fixes in the tcp infrastructure with respect to stack changes as well as other infrastructure updates for incoming rack features. So stack switching as always been a bit of a issue. We currently use a break before make setup which means that if something goes wrong you have to try to get back to a stack. This patch among a lot of other things changes that so that it is a make before break. We also expand some of the function blocks in prep for new features in rack that will allow more controlled pacing. We also add other abilities such as the pathway for a stack to query a previous stack to acquire from it critical state information so things in flight don't get dropped or mis-handled when switching stacks. We also add the concept of a timer granularity. This allows an alternate stack to change from the old ticks granularity to microseconds and of course this even gives us a pathway to go to nanosecond timekeeping if we need to (something for the data center to consider for sure). Once all this lands I will then update rack to begin using all these new features. Reviewed by: tuexen Sponsored by: Netflix Inc Differential Revision: https://reviews.freebsd.org/D39210

# Tarfs debugging
TARFS_DEBUG opt_tarfs.h
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.

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

# SMB/CIFS requester
NETSMB opt_netsmb.h
Split out a more generic debugnet(4) from netdump(4) Debugnet is a simplistic and specialized panic- or debug-time reliable datagram transport. It can drive a single connection at a time and is currently unidirectional (debug/panic machine transmit to remote server only). It is mostly a verbatim code lift from netdump(4). Netdump(4) remains the only consumer (until the rest of this patch series lands). The INET-specific logic has been extracted somewhat more thoroughly than previously in netdump(4), into debugnet_inet.c. UDP-layer logic and up, as much as possible as is protocol-independent, remains in debugnet.c. The separation is not perfect and future improvement is welcome. Supporting INET6 is a long-term goal. Much of the diff is "gratuitous" renaming from 'netdump_' or 'nd_' to 'debugnet_' or 'dn_' -- sorry. I thought keeping the netdump name on the generic module would be more confusing than the refactoring. The only functional change here is the mbuf allocation / tracking. Instead of initiating solely on netdump-configured interface(s) at dumpon(8) configuration time, we watch for any debugnet-enabled NIC for link activation and query it for mbuf parameters at that time. If they exceed the existing high-water mark allocation, we re-allocate and track the new high-water mark. Otherwise, we leave the pre-panic mbuf allocation alone. In a future patch in this series, this will allow initiating netdump from panic ddb(4) without pre-panic configuration. No other functional change intended.

# Enable debugnet(4) networking support.
DEBUGNET opt_global.h
Implement NetGDB(4) NetGDB(4) is a component of a system using a panic-time network stack to remotely debug crashed FreeBSD kernels over the network, instead of traditional serial interfaces. There are three pieces in the complete NetGDB system. First, a dedicated proxy server must be running to accept connections from both NetGDB and gdb(1), and pass bidirectional traffic between the two protocols. Second, the NetGDB client is activated much like ordinary 'gdb' and similarly to 'netdump' in ddb(4) after a panic. Like other debugnet(4) clients (netdump(4)), the network interface on the route to the proxy server must be online and support debugnet(4). Finally, the remote (k)gdb(1) uses 'target remote <proxy>:<port>' (like any other TCP remote) to connect to the proxy server. The NetGDB v1 protocol speaks the literal GDB remote serial protocol, and uses a 1:1 relationship between GDB packets and sequences of debugnet packets (fragmented by MTU). There is no encryption utilized to keep debugging sessions private, so this is only appropriate for local segments or trusted networks.

Support for configuring netdump will be added to dumpon(8) in a future commit. To use netdump, the kernel must have been compiled with the NETDUMP option.

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.

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.

Create a sysctl kern.cam.{,a,n}da.X.invalidate kern.cam.{,a,n}da.X.invalidate=1 forces *daX to detach by calling cam_periph_invalidate on the underlying periph. This is for testing purposes only. Include only with options CAM_TEST_FAILURE and rename the former [AN]DA_TEST_FAILURE, and fix nda to compile with it set. We're using it at work to harden geom and the buffer cache to be resilient in the face of drive failure. Today, it far too often results in a panic. While much work was done on SIM initiated removal for the USB thumnb drive removal work, little has been done for periph initiated removal. This simulates what *daerror() does for some errors nicely: we get the same panics with it that we do with failing drives.

DUMMYNET opt_ipdn.h
Implement kernel support for hardware rate limited sockets. - Add RATELIMIT kernel configuration keyword which must be set to enable the new functionality. - Add support for hardware driven, Receive Side Scaling, RSS aware, rate limited sendqueues and expose the functionality through the already established SO_MAX_PACING_RATE setsockopt(). The API support rates in the range from 1 to 4Gbytes/s which are suitable for regular TCP and UDP streams. The setsockopt(2) manual page has been updated. - Add rate limit function callback API to "struct ifnet" which supports the following operations: if_snd_tag_alloc(), if_snd_tag_modify(), if_snd_tag_query() and if_snd_tag_free(). - Add support to ifconfig to view, set and clear the IFCAP_TXRTLMT flag, which tells if a network driver supports rate limiting or not. - This patch also adds support for rate limiting through VLAN and LAGG intermediate network devices. - How rate limiting works: 1) The userspace application calls setsockopt() after accepting or making a new connection to set the rate which is then stored in the socket structure in the kernel. Later on when packets are transmitted a check is made in the transmit path for rate changes. A rate change implies a non-blocking ifp->if_snd_tag_alloc() call will be made to the destination network interface, which then sets up a custom sendqueue with the given rate limitation parameter. A "struct m_snd_tag" pointer is returned which serves as a "snd_tag" hint in the m_pkthdr for the subsequently transmitted mbufs. 2) When the network driver sees the "m->m_pkthdr.snd_tag" different from NULL, it will move the packets into a designated rate limited sendqueue given by the snd_tag pointer. It is up to the individual drivers how the rate limited traffic will be rate limited. 3) Route changes are detected by the NIC drivers in the ifp->if_transmit() routine when the ifnet pointer in the incoming snd_tag mismatches the one of the network interface. The network adapter frees the mbuf and returns EAGAIN which causes the ip_output() to release and clear the send tag. Upon next ip_output() a new "snd_tag" will be tried allocated. 4) When the PCB is detached the custom sendqueue will be released by a non-blocking ifp->if_snd_tag_free() call to the currently bound network interface.

Introduce stats(3), a flexible statistics gathering API. This provides a framework to define a template describing a set of "variables of interest" and the intended way for the framework to maintain them (for example the maximum, sum, t-digest, or a combination thereof). Afterwards the user code feeds in the raw data, and the framework maintains these variables inside a user-provided, opaque stats blobs. The framework also provides a way to selectively extract the stats from the blobs. The stats(3) framework can be used in both userspace and the kernel. See the stats(3) manual page for details. This will be used by the upcoming TCP statistics gathering code, https://reviews.freebsd.org/D20655.

Add kernel-side support for in-kernel TLS. KTLS adds support for in-kernel framing and encryption of Transport Layer Security (1.0-1.2) data on TCP sockets. KTLS only supports offload of TLS for transmitted data. Key negotation must still be performed in userland. Once completed, transmit session keys for a connection are provided to the kernel via a new TCP_TXTLS_ENABLE socket option. All subsequent data transmitted on the socket is placed into TLS frames and encrypted using the supplied keys. Any data written to a KTLS-enabled socket via write(2), aio_write(2), or sendfile(2) is assumed to be application data and is encoded in TLS frames with an application data type. Individual records can be sent with a custom type (e.g. handshake messages) via sendmsg(2) with a new control message (TLS_SET_RECORD_TYPE) specifying the record type. At present, rekeying is not supported though the in-kernel framework should support rekeying. KTLS makes use of the recently added unmapped mbufs to store TLS frames in the socket buffer. Each TLS frame is described by a single ext_pgs mbuf. The ext_pgs structure contains the header of the TLS record (and trailer for encrypted records) as well as references to the associated TLS session. KTLS supports two primary methods of encrypting TLS frames: software TLS and ifnet TLS. Software TLS marks mbufs holding socket data as not ready via M_NOTREADY similar to sendfile(2) when TLS framing information is added to an unmapped mbuf in ktls_frame(). ktls_enqueue() is then called to schedule TLS frames for encryption. In the case of sendfile_iodone() calls ktls_enqueue() instead of pru_ready() leaving the mbufs marked M_NOTREADY until encryption is completed. For other writes (vn_sendfile when pages are available, write(2), etc.), the PRUS_NOTREADY is set when invoking pru_send() along with invoking ktls_enqueue(). A pool of worker threads (the "KTLS" kernel process) encrypts TLS frames queued via ktls_enqueue(). Each TLS frame is temporarily mapped using the direct map and passed to a software encryption backend to perform the actual encryption. (Note: The use of PHYS_TO_DMAP could be replaced with sf_bufs if someone wished to make this work on architectures without a direct map.) KTLS supports pluggable software encryption backends. Internally, Netflix uses proprietary pure-software backends. This commit includes a simple backend in a new ktls_ocf.ko module that uses the kernel's OpenCrypto framework to provide AES-GCM encryption of TLS frames. As a result, software TLS is now a bit of a misnomer as it can make use of hardware crypto accelerators. Once software encryption has finished, the TLS frame mbufs are marked ready via pru_ready(). At this point, the encrypted data appears as regular payload to the TCP stack stored in unmapped mbufs. ifnet TLS permits a NIC to offload the TLS encryption and TCP segmentation. In this mode, a new send tag type (IF_SND_TAG_TYPE_TLS) is allocated on the interface a socket is routed over and associated with a TLS session. TLS records for a TLS session using ifnet TLS are not marked M_NOTREADY but are passed down the stack unencrypted. The ip_output_send() and ip6_output_send() helper functions that apply send tags to outbound IP packets verify that the send tag of the TLS record matches the outbound interface. If so, the packet is tagged with the TLS send tag and sent to the interface. The NIC device driver must recognize packets with the TLS send tag and schedule them for TLS encryption and TCP segmentation. If the the outbound interface does not match the interface in the TLS send tag, the packet is dropped. In addition, a task is scheduled to refresh the TLS send tag for the TLS session. If a new TLS send tag cannot be allocated, the connection is dropped. If a new TLS send tag is allocated, however, subsequent packets will be tagged with the correct TLS send tag. (This latter case has been tested by configuring both ports of a Chelsio T6 in a lagg and failing over from one port to another. As the connections migrated to the new port, new TLS send tags were allocated for the new port and connections resumed without being dropped.) ifnet TLS can be enabled and disabled on supported network interfaces via new '[-]txtls[46]' options to ifconfig(8). ifnet TLS is supported across both vlan devices and lagg interfaces using failover, lacp with flowid enabled, or lacp with flowid enabled. Applications may request the current KTLS mode of a connection via a new TCP_TXTLS_MODE socket option. They can also use this socket option to toggle between software and ifnet TLS modes. In addition, a testing tool is available in tools/tools/switch_tls. This is modeled on tcpdrop and uses similar syntax. However, instead of dropping connections, -s is used to force KTLS connections to switch to software TLS and -i is used to switch to ifnet TLS. Various sysctls and counters are available under the kern.ipc.tls sysctl node. The kern.ipc.tls.enable node must be set to true to enable KTLS (it is off by default). The use of unmapped mbufs must also be enabled via kern.ipc.mb_use_ext_pgs to enable KTLS. KTLS is enabled via the KERN_TLS kernel option. This patch is the culmination of years of work by several folks including Scott Long and Randall Stewart for the original design and implementation; Drew Gallatin for several optimizations including the use of ext_pgs mbufs, the M_NOTREADY mechanism for TLS records awaiting software encryption, and pluggable software crypto backends; and John Baldwin for modifications to support hardware TLS offload.

netlink: add netlink KPI to the kernel by default This change does the following: Base Netlink KPIs (ability to register the family, parse and/or write a Netlink message) are always present in the kernel. Specifically, * Implementation of genetlink family/group registration/removal, some base accessors (netlink_generic_kpi.c, 260 LoC) are compiled in unconditionally. * Basic TLV parser functions (netlink_message_parser.c, 507 LoC) are compiled in unconditionally. * Glue functions (netlink<>rtsock), malloc/core sysctl definitions (netlink_glue.c, 259 LoC) are compiled in unconditionally. * The rest of the KPI _functions_ are defined in the netlink_glue.c, but their implementation calls a pointer to either the stub function or the actual function, depending on whether the module is loaded or not. This approach allows to have only 1k LoC out of ~3.7k LoC (current sys/netlink implementation) in the kernel, which will not grow further. It also allows for the generic netlink kernel customers to load successfully without requiring Netlink module and operate correctly once Netlink module is loaded.

Introduce scalable route multipath. This change is based on the nexthop objects landed in D24232. The change introduces the concept of nexthop groups. Each group contains the collection of nexthops with their relative weights and a dataplane-optimized structure to enable efficient nexthop selection. Simular to the nexthops, nexthop groups are immutable. Dataplane part gets compiled during group creation and is basically an array of nexthop pointers, compiled w.r.t their weights. With this change, `rt_nhop` field of `struct rtentry` contains either nexthop or nexthop group. They are distinguished by the presense of NHF_MULTIPATH flag. All dataplane lookup functions returns pointer to the nexthop object, leaving nexhop groups details inside routing subsystem. User-visible changes: The change is intended to be backward-compatible: all non-mpath operations should work as before with ROUTE_MPATH and net.route.multipath=1. All routes now comes with weight, default weight is 1, maximum is 2^24-1. Current maximum multipath group width is statically set to 64. This will become sysctl-tunable in the followup changes.

Framework takes care of handling initial synchronisation, route subscription, nhop/nhop groups reference and indexing, dataplane attachments and fib instance algorithm setup/teardown. Framework features automatic algorithm selection, allowing for picking the best matching algorithm on-the-fly based on the amount of routes in the routing table. Currently framework code is guarded under FIB_ALGO config option. An idea is to enable it by default in the next couple of weeks. The following algorithms are provided by default: IPv4: * bsearch4 (lockless binary search in a special IP array), tailored for small-fib (<16 routes) * radix4_lockless (lockless immutable radix, re-created on every rtable change), tailored for small-fib (<1000 routes) * radix4 (base system radix backend) * dpdk_lpm4 (DPDK DIR24-8-based lookups), lockless datastrucure, optimized for large-fib (D27412) IPv6: * radix6_lockless (lockless immutable radix, re-created on every rtable change), tailed for small-fib (<1000 routes) * radix6 (base system radix backend) * dpdk_lpm6 (DPDK DIR24-8-based lookups), lockless datastrucure, optimized for large-fib (D27412) Performance changes: Micro benchmarks (I7-7660U, single-core lookups, 2048k dst, code in D27604): IPv4: 8 routes: radix4: ~20mpps radix4_lockless: ~24.8mpps bsearch4: ~69mpps dpdk_lpm4: ~67 mpps 700k routes: radix4_lockless: 3.3mpps dpdk_lpm4: 46mpps IPv6: 8 routes: radix6_lockless: ~20mpps dpdk_lpm6: ~70mpps 100k routes: radix6_lockless: 13.9mpps dpdk_lpm6: 57mpps Forwarding benchmarks: + 10-15% IPv4 forwarding performance (small-fib, bsearch4) + 25% IPv4 forwarding performance (full-view, dpdk_lpm4) + 20% IPv6 forwarding performance (full-view, dpdk_lpm6) Control: Framwork adds the following runtime sysctls: List algos * net.route.algo.inet.algo_list: bsearch4, radix4_lockless, radix4 * net.route.algo.inet6.algo_list: radix6_lockless, radix6, dpdk_lpm6 Debug level (7=LOG_DEBUG, per-route) net.route.algo.debug_level: 5 Algo selection (currently only for fib 0): net.route.algo.inet.algo: bsearch4 net.route.algo.inet6.algo: radix6_lockless Support for manually changing algos in non-default fib will be added soon.

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.

There are times when it would be really nice to have a record of the last few packets and/or state transitions from each TCP socket. That would help with narrowing down certain problems we see in the field that are hard to reproduce without understanding the history of how we got into a certain state. This change provides just that. It saves copies of the last N packets in a list in the tcpcb. When the tcpcb is destroyed, the list is freed. I thought this was likely to be more performance-friendly than saving copies of the tcpcb. Plus, with the packets, you should be able to reverse-engineer what happened to the tcpcb. To enable the feature, you will need to compile a kernel with the TCPPCAP option. Even then, the feature defaults to being deactivated. You can activate it by setting a positive value for the number of captured packets. You can do that on either a global basis or on a per-socket basis (via a setsockopt call). There is no way to get the packets out of the kernel other than using kmem or getting a coredump. I thought that would help some of the legal/privacy concerns regarding such a feature. However, it should be possible to add a future effort to export them in PCAP format. I tested this at low scale, and found that there were no mbuf leaks and the peak mbuf usage appeared to be unchanged with and without the feature. The main performance concern I can envision is the number of mbufs that would be used on systems with a large number of sockets. If you save five packets per direction per socket and have 3,000 sockets, that will consume at least 30,000 mbufs just to keep these packets. I tried to reduce the concerns associated with this by limiting the number of clusters (not mbufs) that could be used for this feature. Again, in my testing, that appears to work correctly.

tcp: embed inpcb into tcpcb For the TCP protocol inpcb storage specify allocation size that would provide space to most of the data a TCP connection needs, embedding into struct tcpcb several structures, that previously were allocated separately. The most import one is the inpcb itself. With embedding we can provide strong guarantee that with a valid TCP inpcb the tcpcb is always valid and vice versa. Also we reduce number of allocs/frees per connection. The embedded inpcb is placed in the beginning of the struct tcpcb, since in_pcballoc() requires that. However, later we may want to move it around for cache line efficiency, and this can be done with a little effort. The new intotcpcb() macro is ready for such move. The congestion algorithm data, the TCP timers and osd(9) data are also embedded into tcpcb, and temprorary struct tcpcb_mem goes away. There was no extra allocation here, but we went through extra pointer every time we accessed this data. One interesting side effect is that now TCP data is allocated from SMR-protected zone. Potentially this allows the TCP stacks or other TCP related modules to utilize that for their own synchronization. Large part of the change was done with sed script: s/tp->ccv->/tp->t_ccv./g s/tp->ccv/\&tp->t_ccv/g s/tp->cc_algo/tp->t_cc/g s/tp->t_timers->tt_/tp->tt_/g s/CCV\(ccv, osd\)/\&CCV(ccv, t_osd)/g Dependency side effect is that code that needs to know struct tcpcb should also know struct inpcb, that added several <netinet/in_pcb.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.

They both are my two key other developers working on the project.. and they need ata-boy's too: **** peterlei@cisco.com tuexen@fh-muenster.de **** I did do a make sysent which updated the syscall's and sysproto.. I hope that is correct... without it you don't build since we have new syscalls for SCTP :-0 So go out and look at the NOTES, add option SCTP (make sure inet and inet6 are present too) and play with SCTP.

I also have a lib (libsctp.a) that adds some of the missing socketapi functions that I need to put into lib's..

SCTP opt_sctp.h
Add the SCTP_SUPPORT kernel option. This is in preparation for enabling a loadable SCTP stack. Analogous to IPSEC/IPSEC_SUPPORT, the SCTP_SUPPORT kernel option must be configured in order to support a loadable SCTP implementation.

SCTP_SUPPORT opt_sctp.h
- Fix so ifn's are properly deleted when the ref count goes to 0. - Fix so VRF's will clean themselves up when no references are around. - Allow sctp_ifa to be passed into inpcb_bind, addr_mgmt_ep_sa to bypass normal validation checks. - turn auto-asconf off for subset bound sockets - Moves all logging to use KTR. This gets rid of most of the logging #ifdef's with a few exceptions reducing the number of config options for SCTP.

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.

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.

KASSERT: Make runtime optionality optional Add an option, KASSERT_PANIC_OPTIONAL, that allows runtime KASSERT() behavior changes. When this option is not enabled, code that allows KASSERTs to become optional is not enabled, and all violated assertions cause termination. The runtime KASSERT behavior was added in r243980. One important distinction here is that panic has __dead2 ("attribute((noreturn))"), while kassert_panic does not. Static analyzers like Coverity understand __dead2. Without it, KASSERTs go misunderstood, resulting in many false positives that result from violation of program invariants.

Make MAXPHYS tunable. Bump MAXPHYS to 1M. Replace MAXPHYS by runtime variable maxphys. It is initialized from MAXPHYS by default, but can be also adjusted with the tunable kern.maxphys. Make b_pages[] array in struct buf flexible. Size b_pages[] for buffer cache buffers exactly to atop(maxbcachebuf) (currently it is sized to atop(MAXPHYS)), and b_pages[] for pbufs is sized to atop(maxphys) + 1. The +1 for pbufs allow several pbuf consumers, among them vmapbuf(), to use unaligned buffers still sized to maxphys, esp. when such buffers come from userspace (*). Overall, we save significant amount of otherwise wasted memory in b_pages[] for buffer cache buffers, while bumping MAXPHYS to desired high value. Eliminate all direct uses of the MAXPHYS constant in kernel and driver sources, except a place which initialize maxphys. Some random (and arguably weird) uses of MAXPHYS, e.g. in linuxolator, are converted straight. Some drivers, which use MAXPHYS to size embeded structures, get private MAXPHYS-like constant; their convertion is out of scope for this work.

REGRESSION opt_global.h
Add a basic reader/writer lock implementation to the kernel. 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.

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

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.

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.

# Standard SMP options
Add an EARLY_AP_STARTUP option to start APs earlier during boot. Currently, Application Processors (non-boot CPUs) are started by MD code at SI_SUB_CPU, but they are kept waiting in a "pen" until SI_SUB_SMP at which point they are released to run kernel threads. SI_SUB_SMP is one of the last SYSINIT levels, so APs don't enter the scheduler and start running threads until fairly late in the boot. This change moves SI_SUB_SMP up to just before software interrupt threads are created allowing the APs to start executing kernel threads much sooner (before any devices are probed). This allows several initialization routines that need to perform initialization on all CPUs to now perform that initialization in one step rather than having to defer the AP initialization to a second SYSINIT run at SI_SUB_SMP. It also permits all CPUs to be available for handling interrupts before any devices are probed. This last feature fixes a problem on with interrupt vector exhaustion. Specifically, in the old model all device interrupts were routed onto the boot CPU during boot. Later after the APs were released at SI_SUB_SMP, interrupts were redistributed across all CPUs. However, several drivers for multiqueue hardware allocate N interrupts per CPU in the system. In a system with many CPUs, just a few drivers doing this could exhaust the available pool of interrupt vectors on the boot CPU as each driver was allocating N * mp_ncpu vectors on the boot CPU. Now, drivers will allocate interrupts on their desired CPUs during boot meaning that only N interrupts are allocated from the boot CPU instead of N * mp_ncpu. Some other bits of code can also be simplified as smp_started is now true much earlier and will now always be true for these bits of code. This removes the need to treat the single-CPU boot environment as a special case. As a transition aid, the new behavior is available under a new kernel option (EARLY_AP_STARTUP). This will allow the option to be turned off if need be during initial testing. I plan to enable this on x86 by default in a followup commit in the next few days and to have all platforms moved over before 11.0. Once the transition is complete, the option will be removed along with the !EARLY_AP_STARTUP code. These changes have only been tested on x86. Other platform maintainers are encouraged to port their architectures over as well. The main things to check for are any uses of smp_started in MD code that can be simplified and SI_SUB_SMP SYSINITs in MD code that can be removed in the EARLY_AP_STARTUP case (e.g. the interrupt shuffling).

INIT_PATH
Major lobotomy of config(8). The config kernel mumble mumble line has been obsoleted and removed and with it went all knowledge of devices on the part of config. You can still configure a root device (which is used if you give the "-r" flag) but now with an option: options ROOTDEVNAME=\"da0s2e\" The string is parsed by the same code as at the "boot -a" prompt. At the same time, make the "boot -a" prompt both more able and more informative. ALPHA/PC98 people: You will have to adapt a few simple changes (defining rootdev and dumpdev somewhere else) before config works for you again, sorry, but it's all in the name of progress.

Connect the restored dumb and sc terminal emulators to the kernel build. Add or fix options to control static and dynamic configuration. Keep the default of scteken, but default to statically configuring all available emulators (now 3 instead of 1). The dumb emulator is almost usable. libedit and libreadline handle dumb terminals perfectly for at least shell history. less(1) works as well as possible except on exit. But curses programs make messes. The dumb emulator has strange color support, with 2 dumb colors for normal output but fancy colorization for the cursor, mouse pointer and (with a non-dumb initial emulator) for low-level console output. Using the sc emulator instead of the default of scteken fixes at least the following bugs: - NUL is a printing character in cons25 but not in teken - teken doesn't support fixed colors for "reverse" video. - The best versions of sc are about 10 times faster than scteken (for printing to the frame buffer). This version is only about 5 times faster. Fix configuration features: - make SC_DFLT_TERM (for setting the initial emulator) a normal option. Add configuration features: - negative options SC_NO_TERM_* for omitting emulators in the static config. Modules for emulators might work, but I don't know of any - vidcontrol -e shows the available emulators - vidcontrol -E <emulator> sets the active emulator.

Connect the restored dumb and sc terminal emulators to the kernel build. Add or fix options to control static and dynamic configuration. Keep the default of scteken, but default to statically configuring all available emulators (now 3 instead of 1). The dumb emulator is almost usable. libedit and libreadline handle dumb terminals perfectly for at least shell history. less(1) works as well as possible except on exit. But curses programs make messes. The dumb emulator has strange color support, with 2 dumb colors for normal output but fancy colorization for the cursor, mouse pointer and (with a non-dumb initial emulator) for low-level console output. Using the sc emulator instead of the default of scteken fixes at least the following bugs: - NUL is a printing character in cons25 but not in teken - teken doesn't support fixed colors for "reverse" video. - The best versions of sc are about 10 times faster than scteken (for printing to the frame buffer). This version is only about 5 times faster. Fix configuration features: - make SC_DFLT_TERM (for setting the initial emulator) a normal option. Add configuration features: - negative options SC_NO_TERM_* for omitting emulators in the static config. Modules for emulators might work, but I don't know of any - vidcontrol -e shows the available emulators - vidcontrol -E <emulator> sets the active emulator.

# 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@

TEKEN_UTF8 opt_teken.h
In order to get vt(4) a bit closer to the feature set provided by sc(4), implement options TERMINAL_{KERN,NORM}_ATTR. These are aliased to SC_{KERNEL_CONS,NORM}_ATTR and like these latter, allow to change the default colors of normal and kernel text respectively. 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. Actually, if the architecture and abstraction of terminal+teken+vt would be perfect, dev/vt/* wouldn't be touched by this commit at all.

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.

BOOT_TAG: Make a config(5) option, expose as sysctl and loader tunable BOOT_TAG lived shortly in sys/msgbuf.h, but this wasn't necessarily great for changing it or removing it. Move it into subr_prf.c and add options for it to opt_printf.h. One can specify both the BOOT_TAG and BOOT_TAG_SZ (really, size of the buffer that holds the BOOT_TAG). We expose it as kern.boot_tag and also add a loader tunable by the same name that we'll fetch upon initialization of the msgbuf. This allows for flexibility and also ensures that there's a consistent way to figure out the boot tag of the running kernel, rather than relying on headers to be in-sync.

This includes a few new fields in each RXed frame: * per chain RX RSSI (ctl and ext); * current RX chainmask; * EVM information; * PHY error code; * basic RX status bits (CRC error, PHY error, etc). 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. Instead, add the option 'ATH_ENABLE_RADIOTAP_VENDOR_EXT' to your kernel configuration file to enable these options.

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@

Introduce bwn(4) support for the bhnd(4) bus. Currently, bwn(4) relies on the siba_bwn(4) bus driver to provide support for the on-chip SSB interconnect found in Broadcom's older PCI(e) Wi-Fi adapters. Non-PCI Wi-Fi adapters, as well as the newer BCMA interconnect found in post-2009 Broadcom Wi-Fi hardware, are not supported by siba_bwn(4). The bhnd(4) bus driver (also used by the FreeBSD/MIPS Broadcom port) provides a unified kernel interface to a superset of the hardware supported by siba_bwn; by attaching bwn(4) via bhnd(4), we can support both modern PCI(e) Wi-Fi devices based on the BCMA backplane interconnect, as well as Broadcom MIPS WiSoCs that include a D11 MAC core directly attached to their SSB or BCMA backplane. This diff introduces opt-in bwn(4) support for bhnd(4) by providing: - A small bwn(4) driver subclass, if_bwn_bhnd, that attaches via bhnd(4) instead of siba_bwn(4). - A bhndb(4)-based PCI host bridge driver, if_bwn_pci, that optionally probes at a higher priority than the siba_bwn(4) PCI driver. - A set of compatibility shims that perform translation of bwn(4)'s siba_bwn function calls into their bhnd(9) API equivalents when bwn(4) is attached via a bhnd(4) bus parent. When bwn(4) is attached via siba_bwn(4), all siba_bwn function calls are simply passed through to their original implementations. To test bwn(4) with bhnd(4), place the following lines in loader.conf(5): hw.bwn_pci.preferred="1" if_bwn_pci_load="YES bwn_v4_ucode_load="YES" bwn_v4_lp_ucode_load="YES" To verify that bwn(4) is using bhnd(4), you can check dmesg: bwn0: <Broadcom 802.11 MAC/PHY/Radio, rev 15> ... on bhnd0 ... or devinfo(8): pcib2 pci2 bwn_pci0 bhndb0 bhnd0 bwn0 ... bwn(4)/bhnd(4) has been tested for regressions with most chipsets currently supported by bwn(4), including: - BCM4312 - BCM4318 - BCM4321 With minimal changes to the DMA code (not included in this commit), I was also able to test support for newer BCMA devices by bringing up basic working Wi-Fi on two previously unsupported, BCMA-based N-PHY chipsets: - BCM43224 - BCM43225 Approved by: adrian (mentor, implicit) Sponsored by: The FreeBSD Foundation & Plausible Labs Differential Revision: https://reviews.freebsd.org/D13041

IEEE80211_DEBUG opt_wlan.h
IEEE80211_DEBUG_REFCNT 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.

# Random number generator(s)
Add "Fenestras X" alternative /dev/random implementation Fortuna remains the default; no functional change to GENERIC. Big picture: - Scalable entropy generation with per-CPU, buffered local generators. - "Push" system for reseeding child generators when root PRNG is reseeded. (Design can be extended to arc4random(9) and userspace generators.) - Similar entropy pooling system to Fortuna, but starts with a single pool to quickly bootstrap as much entropy as possible early on. - Reseeding from pooled entropy based on time schedule. The time interval starts small and grows exponentially until reaching a cap. Again, the goal is to have the RNG state depend on as much entropy as possible quickly, but still periodically incorporate new entropy for the same reasons as Fortuna. Notable design choices in this implementation that differ from those specified in the whitepaper: - Blake2B instead of SHA-2 512 for entropy pooling - Chacha20 instead of AES-CTR DRBG - Initial seeding. We support more platforms and not all of them use loader(8). So we have to grab the initial entropy sources in kernel mode instead, as much as possible. Fortuna didn't have any mechanism for this aside from the special case of loader-provided previous-boot entropy, so most of these sources remain TODO after this commit.

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.

Incorporate bus and chip select numbers into spigen(4) cdev names. Rather than assigning spigen device names in order of creation, this uses a device name that corresponds to the owning spibus and chip-select index. Example: /dev/spigen0.1 would be a child of spibus0, and use cs = 1 The intent is for systems like Raspberry Pi to have a consistent way of using an SPI interface with a specific cs value from a user application. Otherwise, there is no consistent way of knowing which cs pin will be assigned to a particular spigen device. The alternative is to specify everything in "the right order" in an overlay file, which is less than ideal. Additionally, this duplicates (to some extent) the way Linux handles a similar situation with their 'spidev' device, so it would be somewhat familiar to those who also use Linux. A new kernel config option, SPIGEN_LEGACY_CDEVNAME, causes the driver to also create /dev/spigenN device name aliases, with N incrementing in the order of device instantiation. This is provided to ease the transition for existing systems using the original naming convention (particularly when these changes are MFC'd to stable branches).

Add support for encrypted kernel crash dumps. Changes include modifications in kernel crash dump routines, dumpon(8) and savecore(8). A new tool called decryptcore(8) was added. A new DIOCSKERNELDUMP I/O control was added to send a kernel crash dump configuration in the diocskerneldump_arg structure to the kernel. The old DIOCSKERNELDUMP I/O control was renamed to DIOCSKERNELDUMP_FREEBSD11 for backward ABI compatibility. dumpon(8) generates an one-time random symmetric key and encrypts it using an RSA public key in capability mode. Currently only AES-256-CBC is supported but EKCD was designed to implement support for other algorithms in the future. The public key is chosen using the -k flag. The dumpon rc(8) script can do this automatically during startup using the dumppubkey rc.conf(5) variable. Once the keys are calculated dumpon sends them to the kernel via DIOCSKERNELDUMP I/O control. When the kernel receives the DIOCSKERNELDUMP I/O control it generates a random IV and sets up the key schedule for the specified algorithm. Each time the kernel tries to write a crash dump to the dump device, the IV is replaced by a SHA-256 hash of the previous value. This is intended to make a possible differential cryptanalysis harder since it is possible to write multiple crash dumps without reboot by repeating the following commands: # sysctl debug.kdb.enter=1 db> call doadump(0) db> continue # savecore A kernel dump key consists of an algorithm identifier, an IV and an encrypted symmetric key. The kernel dump key size is included in a kernel dump header. The size is an unsigned 32-bit integer and it is aligned to a block size. The header structure has 512 bytes to match the block size so it was required to make a panic string 4 bytes shorter to add a new field to the header structure. If the kernel dump key size in the header is nonzero it is assumed that the kernel dump key is placed after the first header on the dump device and the core dump is encrypted. Separate functions were implemented to write the kernel dump header and the kernel dump key as they need to be unencrypted. The dump_write function encrypts data if the kernel was compiled with the EKCD option. Encrypted kernel textdumps are not supported due to the way they are constructed which makes it impossible to use the CBC mode for encryption. It should be also noted that textdumps don't contain sensitive data by design as a user decides what information should be dumped. savecore(8) writes the kernel dump key to a key.# file if its size in the header is nonzero. # is the number of the current core dump. decryptcore(8) decrypts the core dump using a private RSA key and the kernel dump key. This is performed by a child process in capability mode. If the decryption was not successful the parent process removes a partially decrypted core dump. Description on how to encrypt crash dumps was added to the decryptcore(8), dumpon(8), rc.conf(5) and savecore(8) manual pages. EKCD was tested on amd64 using bhyve and i386, mipsel and sparc64 using QEMU. The feature still has to be tested on arm and arm64 as it wasn't possible to run FreeBSD due to the problems with QEMU emulation and lack of hardware.

An MMC/SD/SDIO stack using CAM Implement the MMC/SD/SDIO protocol within a CAM framework. CAM's flexible queueing will make it easier to write non-storage drivers than the legacy stack. SDIO drivers from both the kernel and as userland daemons are possible, though much of that functionality will come later. Some of the CAM integration isn't complete (there are sleeps in the device probe state machine, for example), but those minor issues can be improved in-tree more easily than out of tree and shouldn't gate progress on other fronts.

Should there be a situation when you need a second reset (for buggy or at least somewhat out of the mainstream hardware), the hardware option NVME_2X_RESET will restore the old behavior.
