struct ifconf and struct ifreq use the odd style "struct<tab>foo". struct ifdrv seems to have tried to follow this but was committed with spaces in place of most tabs resulting in "struct<space><space>ifdrv".

Use an accessor to access ifgr_group and ifgr_groups.
Use an macro CASE_IOC_IFGROUPREQ(cmd) in place of case statements such as "case SIOCAIFGROUP:". This avoids poluting the switch statements with large numbers of #ifdefs.

if: Add ioctls to get RSS key and hash type/function.
It will be needed by hn(4) to configure its RSS key and hash type/function in the transparent VF mode in order to match VF's RSS settings. The description of the transparent VF mode and the RSS hash value issue are here: https://svnweb.freebsd.org/base?view=revision&revision=322299 https://svnweb.freebsd.org/base?view=revision&revision=322485
These are generic enough to promise two independent IOCs instead of abusing SIOCGDRVSPEC.
Setting RSS key and hash type/function is a different story, which probably requires more discussion.
Comment about UDP_{IPV4,IPV6,IPV6_EX} were only in the patch in the review request; these hash types are standardized now.

Since 32-bit if_baudrate isn't enough to describe a baud rate of a 10 Gbit interface, in the r241616 a crutch was provided. It didn't work well, and finally we decided that it is time to break ABI and simply make if_baudrate a 64-bit value. Meanwhile, the entire struct if_data was reviewed.
o Remove the if_baudrate_pf crutch.
o Make all fields of struct if_data fixed machine independent size. The notion of data (packet counters, etc) are by no means MD. And it is a bug that on amd64 we've got a 64-bit counters, while on i386 32-bit, which at modern speeds overflow within a second.
This also removes quite a lot of COMPAT_FREEBSD32 code.
o Give 16 bit for the ifi_datalen field. This field was provided to make future changes to if_data less ABI breaking. Unfortunately the 8 bit size of it had effectively limited sizeof if_data to 256 bytes.
o Give 32 bits to ifi_mtu and ifi_metric. o Give 64 bits to the rest of fields, since they are counters.
__FreeBSD_version bumped.

Restructure the mbuf pkthdr to make it fit for upcoming capabilities and features. The changes in particular are:
o Remove rarely used "header" pointer and replace it with a 64bit protocol/ layer specific union PH_loc for local use. Protocols can flexibly overlay their own 8 to 64 bit fields to store information while the packet is worked on.
o Mechanically convert IP reassembly, IGMP/MLD and ATM to use pkthdr.PH_loc instead of pkthdr.header.
o Extend csum_flags to 64bits to allow for additional future offload information to be carried (e.g. iSCSI, IPsec offload, and others).
o Move the RSS hash type enumerator from abusing m_flags to its own 8bit rsstype field. Adjust accessor macros.
o Add cosqos field to store Class of Service / Quality of Service information with the packet. It is not yet supported in any drivers but allows us to get on par with Cisco/Juniper in routing applications (plus MPLS QoS) with a modernized ALTQ.
o Add four 8 bit fields l[2-5]hlen to store the relative header offsets from the start of the packet. This is important for various offload capabilities and to relieve the drivers from having to parse the packet and protocol headers to find out location of checksums and other information. Header parsing in drivers is a lot of copy-paste and unhandled corner cases which we want to avoid.
o Add another flexible 64bit union to map various additional persistent packet information, like ether_vtag, tso_segsz and csum fields. Depending on the csum_flags settings some fields may have different usage making it very flexible and adaptable to future capabilities.
o Restructure the CSUM flags to better signify their outbound (down the stack) and inbound (up the stack) use. The CSUM flags used to be a bit chaotic and rather poorly documented leading to incorrect use in many places. Bring clarity into their use through better naming. Compatibility mappings are provided to preserve the API. The drivers can be corrected one by one and MFC'd without issue.
o The size of pkthdr stays the same at 48/56bytes (32/64bit architectures).

real ifi_baudrate = ifi_baudrate * 10 ^ ifi_baudrate power factor
this should be backwards compatible with old binaries. use ixgbe(4) as an example on how drivers would set ifi_baudrate power factor

It turns out that too many drivers are not only parsing the L2/3/4 headers for TSO but also for generic checksum offloading. Ideally we would only have one common function shared amongst all drivers, and perhaps when updating them for IPv6 we should introduce that. Eventually we should provide the meta information along with mbufs to avoid (re-)parsing entirely.
To not break IPv6 (checksums and offload) and to be able to MFC the changes without risking to hurt 3rd party drivers, duplicate the v4 framework, as other OSes have done as well.
Introduce interface capability flags for TX/RX checksum offload with IPv6, to allow independent toggling (where possible). Add CSUM_*_IPV6 flags for UDP/TCP over IPv6, and reserve further for SCTP, and IPv6 fragmentation. Define CSUM_DELAY_DATA_IPV6 as we do for legacy IP and add an alias for CSUM_DATA_VALID_IPV6.
This pretty much brings IPv6 handling in line with IPv4. TSO is still handled in a different way and not via if_hwassist.
Update ifconfig to allow (un)setting of the new capability flags. Update loopback to announce the new capabilities and if_hwassist flags.
Individual driver updates will have to follow, as will SCTP.

A major overhaul of the CARP implementation. The ip_carp.c was started from scratch, copying needed functionality from the old implemenation on demand, with a thorough review of all code. The main change is that interface layer has been removed from the CARP. Now redundant addresses are configured exactly on the interfaces, they run on.
The CARP configuration itself is, as before, configured and read via SIOCSVH/SIOCGVH ioctls. A new prefix created with SIOCAIFADDR or SIOCAIFADDR_IN6 may now be configured to a particular virtual host id, which makes the prefix redundant.
ifconfig(8) semantics has been changed too: now one doesn't need to clone carpXX interface, he/she should directly configure a vhid on a Ethernet interface.
To supply vhid data from the kernel to an application the getifaddrs(8) function had been changed to pass ifam_data with each address. [1]
The new implementation definitely closes all PRs related to carp(4) being an interface, and may close several others. It also allows to run a single redundant IP per interface.
Big thanks to Bjoern Zeeb for his help with inet6 part of patch, for idea on using ifam_data and for several rounds of reviewing!

When user_frac in the polling subsystem is low it is going to busy the CPU for too long period than necessary. Additively, interfaces are kept polled (in the tick) even if no more packets are available. In order to avoid such situations a new generic mechanism can be implemented in proactive way, keeping track of the time spent on any packet and fragmenting the time for any tick, stopping the processing as soon as possible.
In order to implement such mechanism, the polling handler needs to change, returning the number of packets processed. While the intended logic is not part of this patch, the polling KPI is broken by this commit, adding an int return value and the new flag IFCAP_POLLING_NOCOUNT (which will signal that the return value is meaningless for the installed handler and checking should be skipped).
Bump __FreeBSD_version in order to signal such situation.

ifnet_byindex_ref() checks for IFF_DYING and returns NULL if it is set, preventing new references from by acquired by index, preventing monitoring sysctls from seeing it. Other lookup mechanisms currently do not check IFF_DYING, but may need to in the future.

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

Big polling(4) cleanup.
o Axe poll in trap.
o Axe IFF_POLLING flag from if_flags.
o Rework revision 1.21 (Giant removal), in such a way that poll_mtx is not dropped during call to polling handler. This fixes problem with idle polling.
o Make registration and deregistration from polling in a functional way, insted of next tick/interrupt.
o Obsolete kern.polling.enable. Polling is turned on/off with ifconfig.
Detailed kern_poll.c changes: - Remove polling handler flags, introduced in 1.21. The are not needed now. - Forget and do not check if_flags, if_capenable and if_drv_flags. - Call all registered polling handlers unconditionally. - Do not drop poll_mtx, when entering polling handlers. - In ether_poll() NET_LOCK_GIANT prior to locking poll_mtx. - In netisr_poll() axe the block, where polling code asks drivers to unregister. - In netisr_poll() and ether_poll() do polling always, if any handlers are present. - In ether_poll_[de]register() remove a lot of error hiding code. Assert that arguments are correct, instead. - In ether_poll_[de]register() use standard return values in case of error or success. - Introduce poll_switch() that is a sysctl handler for kern.polling.enable. poll_switch() goes through interface list and enabled/disables polling. A message that kern.polling.enable is deprecated is printed.
Detailed driver changes: - On attach driver announces IFCAP_POLLING in if_capabilities, but not in if_capenable. - On detach driver calls ether_poll_deregister() if polling is enabled. - In polling handler driver obtains its lock and checks IFF_DRV_RUNNING flag. If there is no, then unlocks and returns. - In ioctl handler driver checks for IFCAP_POLLING flag requested to be set or cleared. Driver first calls ether_poll_[de]register(), then obtains driver lock and [dis/en]ables interrupts. - In interrupt handler driver checks IFCAP_POLLING flag in if_capenable. If present, then returns.This is important to protect from spurious interrupts.

For each interface flag, indicate whether or not it is owned by the device driver, owned by the network stack, or initialized by the device driver before attach and read-only from then on.
Not all device drivers and network stack components currently follow these rules, especially with respect to IFF_UP, and a few exceptions with IFF_ALLMULTI.

Rename IFF_RUNNING to IFF_DRV_RUNNING, IFF_OACTIVE to IFF_DRV_OACTIVE, and move both flags from ifnet.if_flags to ifnet.if_drv_flags, making and documenting the locking of these flags the responsibility of the device driver, not the network stack. The flags for these two fields will be mutually exclusive so that they can be exposed to user space as though they were stored in the same variable.
Provide #defines to provide the old names #ifndef _KERNEL, so that user applications (such as ifconfig) can use the old flag names. Using the old names in a device driver will result in a compile error in order to help device driver writers adopt the new model.
When exposing the interface flags to user space, via interface ioctls or routing sockets, or the two fields together. Since the driver flags cannot currently be set for user space, no new logic is currently required to handle this case.
Add some assertions that general purpose network stack routines, such as if_setflags(), are not improperly used on driver-owned flags.
With this change, a large number of very minor network stack races are closed, subject to correct device driver locking. Most were likely never triggered.
Driver sweep to follow; many thanks to pjd and bz for the line-by-line review they gave this patch.

Change the definition of struct if_data's member ifi_epoch from wall clock time to uptime because wall clock time may go backwards.
This is a change in the API which will impact SNMP agents who are using ifi_epoch to set RFC2233's ifCounterDiscontinuityTime. None are know to exist today. This will not impact applications that are using the <index, epoch> tuple to verify interface uniqueness except that it eliminates a race which could lead to a false assumption of uniqueness.
Because this is a behavior change, bump __FreeBSD_version.

Re-add ifi_epoch, to struct if_data, this time replacing ifi_unused to avoid ABI changes. It is set to the last time the interface counters were zeroed, currently the time if_attach() was called. It is intentended to be a valid value for RFC2233's ifCounterDiscontinuityTime and to make it easier for applications to verify that the interface they find at a given index is the one that was there last time they looked.
Due to space constraints ifi_epoch is a time_t rather then a struct timeval. SNMP would prefer higher precision, but this unlikely to be useful in practice.

Add a new network interface flag, IFF_NEEDSGIANT, which will allow device drivers to declare that the ifp->if_start() method implemented by the driver requires Giant in order to operate correctly.
Add a 'struct task' to 'struct ifnet' that can be used to execute a deferred ifp->if_start() in the event that if_start needs to be called in a Giant-free environment. To do this, introduce if_start(), a wrapper function for ifp->if_start(). If the interface can run MPSAFE, it directly dispatches into the interface start routine. If it can't run MPSAFE, we're running with debug.mpsafenet != 0, and Giant isn't currently held, the task is queued to execute in a swi holding Giant via if_start_deferred().
Modify if_handoff() to use if_start() instead of direct dispatch. Modify 802.11 to use if_start() instead of direct dispatch.
This is intended to provide increased compatibility for non-MPSAFE network device drivers in the presence of Giant-free operation via asynchronous dispatch. However, this commit does not mark any network interfaces as IFF_NEEDSGIANT.

Major overhaul of pseudo-interface cloning. Highlights include:
- Split the code out into if_clone.[ch]. - Locked struct if_clone. [1] - Add a per-cloner match function rather then simply matching names of the form <name><unit> and <name>. - Use the match function to allow creation of <interface>.<tag> vlan interfaces. The old way is preserved unchanged! - Also the match function to allow creation of stf(4) interfaces named stf0, stf, or 6to4. This is the only major user visible change in that "ifconfig stf" creates the interface stf rather then stf0 and does not print "stf0" to stdout. - Allow destroy functions to fail so they can refuse to delete interfaces. Currently, we forbid the deletion of interfaces which were created in the init function, particularly lo0, pflog0, and pfsync0. In the case of lo0 this was a panic implementation so it does not count as a user visiable change. :-) - Since most interfaces do not need the new functionality, an family of wrapper functions, ifc_simple_*(), were created to wrap old style cloner functions. - The IF_CLONE_INITIALIZER macro is replaced with a new incompatible IFC_CLONE_INITIALIZER and ifc_simple consumers use IFC_SIMPLE_DECLARE instead.

Device Polling code for -current.
Non-SMP, i386-only, no polling in the idle loop at the moment.
To use this code you must compile a kernel with
options DEVICE_POLLING
and at runtime enable polling with
sysctl kern.polling.enable=1
The percentage of CPU reserved to userland can be set with
sysctl kern.polling.user_frac=NN (default is 50)
while the remainder is used by polling device drivers and netisr's. These are the only two variables that you should need to touch. There are a few more parameters in kern.polling but the default values are adequate for all purposes. See the code in kern_poll.c for more details on them.
Polling in the idle loop will be implemented shortly by introducing a kernel thread which does the job. Until then, the amount of CPU dedicated to polling will never exceed (100-user_frac). The equivalent (actually, better) code for -stable is at
http://info.iet.unipi.it/~luigi/polling/
and also supports polling in the idle loop.
NOTE to Alpha developers: There is really nothing in this code that is i386-specific. If you move the 2 lines supporting the new option from sys/conf/{files,options}.i386 to sys/conf/{files,options} I am pretty sure that this should work on the Alpha as well, just that I do not have a suitable test box to try it. If someone feels like trying it, I would appreciate it.
NOTE to other developers: sure some things could be done better, and as always I am open to constructive criticism, which a few of you have already given and I greatly appreciated. However, before proposing radical architectural changes, please take some time to possibly try out this code, or at the very least read the comments in kern_poll.c, especially re. the reason why I am using a soft netisr and cannot (I believe) replace it with a simple timeout.
Quick description of files touched by this commit:
sys/conf/files.i386 new file kern/kern_poll.c sys/conf/options.i386 new option sys/i386/i386/trap.c poll in trap (disabled by default) sys/kern/kern_clock.c initialization and hardclock hooks. sys/kern/kern_intr.c minor swi_net changes sys/kern/kern_poll.c the bulk of the code. sys/net/if.h new flag sys/net/if_var.h declaration for functions used in device drivers. sys/net/netisr.h NETISR_POLL sys/dev/fxp/if_fxp.c sys/dev/fxp/if_fxpvar.h sys/pci/if_dc.c sys/pci/if_dcreg.h sys/pci/if_sis.c sys/pci/if_sisreg.h device driver modifications

This Implements the mumbled about "Jail" feature.
This is a seriously beefed up chroot kind of thing. The process is jailed along the same lines as a chroot does it, but with additional tough restrictions imposed on what the superuser can do.
For all I know, it is safe to hand over the root bit inside a prison to the customer living in that prison, this is what it was developed for in fact: "real virtual servers".
Each prison has an ip number associated with it, which all IP communications will be coerced to use and each prison has its own hostname.
Needless to say, you need more RAM this way, but the advantage is that each customer can run their own particular version of apache and not stomp on the toes of their neighbors.
It generally does what one would expect, but setting up a jail still takes a little knowledge.
A few notes:
I have no scripts for setting up a jail, don't ask me for them.
The IP number should be an alias on one of the interfaces.
mount a /proc in each jail, it will make ps more useable.
/proc/<pid>/status tells the hostname of the prison for jailed processes.
Quotas are only sensible if you have a mountpoint per prison.
There are no privisions for stopping resource-hogging.
Some "#ifdef INET" and similar may be missing (send patches!)
If somebody wants to take it from here and develop it into more of a "virtual machine" they should be most welcome!
Tools, comments, patches & documentation most welcome.

Add a macro to accurately calculate the length of a struct ifreq when it contains an address. This can replace all the myriad (wrong) ways in which this task is performed in the current system. As an added bonus, since it's a macro, then third-party software vendors have an easy way to tell whether it's there or not.

Use the new if_multiaddrs list for multicast addresses rather than the previous hackery involving struct in_ifaddr and arpcom. Get rid of the abominable multi_kludge. Update all network interfaces to use the new machanism. Distressingly few Ethernet drivers program the multicast filter properly (assuming the hardware has one, which it usually does).

1) Implement SIOCSIFMTU in ether_ioctl(), and change ether_ioctl's return type to be int so that errors can be returned. 2) Use the new SIOCSIFMTU ether_ioctl support in the few drivers that are using ether_ioctl(). 3) In if_fxp.c: treat if_bpf as a token, not as a pointer. Don't bother testing for FXP_NTXSEG being reached in fxp_start()...just check for non-NULL 'm'. Change fxp_ioctl() to use ether_ioctl().

Removed nested include if <sys/socket.h> from <net/if.h> and <net/if_arp.h> and fixed the things that depended on it. The nested include just allowed unportable programs to compile and made my simple #include checking program report that networking code doesn't need to include <sys/socket.h>.

Add better support for retrieving management information from network interfaces. This creates two new tables in the net.link.generic branch of the MIB; one contains (essentially) `ifdata' structures, and the other contains a blob provided by the interface (and presumably used to implement link-layer-specific MIB variables). A number of things have been moved around in the `ifnet' and `ifdata' structures, so NEW VERSIONS OF ifconfig(8) AND routed(8) ARE REQUIRED. (A simple recompile is all that's necessary.)
I have a sample program which uses this interface for those interested in making use of it.

Add a new, better mechanism for sticking packets onto ifqueues. The old system had the misfeature that the only policy it could implement was tail-drop; the new IF_ENQ_DROP macro/function makes it possible to implement more sophisticated queueing policies on a system-wide basis. No code actually uses this yet (although on my machine I have converted the ethernet and (polled) loopback to use it).

Delete the if_private[] array in struct ifnet; this turned out to be of limited utility. In their place, add bunch of pointers which will eventually be needed by the polled-interrupt scheme we're working here. (It will probably be a while before the code is written and committed here.) At the same time, a `void *if_softc' field was added to the beginning of the structure to make certain driver writers happier.
The practical upshot of all this is that you need to recompile utilities such as netstat which manipulate struct ifnet.

all: Removed ifnet.if_init and ifnet.if_reset as they are generally unused. Change the parameter passed to if_watchdog to be a ifnet * rather than a unit number. All of this is an attempt to move toward not needing an array of softc pointers (which is usually static in size) to point to the driver softc.
if_ed.c: Changed some of the argument passing to some functions to make a little more sense.
if_ep.c, if_vx.c: Killed completely bogus use of if_timer. It was being set in such a way that the interface was being reset once per second (blech!).

Add support for two separate cloning flags, one set by the lower layers, and one set by the protocol family. Also add another parameter to rtalloc1() to allow for any interface flags to be ignored; currently this is only useful for RTF_PRCLONING. Get rid of rt_prflags and re-unite with rt_flags. Add T/TCP ``route metrics''.
NB: YOU MUST RECOMPILE `route' AND OTHER RELATED PROGRAMS AS A RESULT OF THIS CHANGE.
This also adds a new interface parameter, `ifi_physical', which will eventually replace IFF_ALTPHYS as the mechanism for specifying the particular physical connection desired on a multiple-connection card.
NB: YOU MUST RECOMPILE `ifconfig' AND OTHER RELATED PROGRAMS AS A RESULT OF THIS CHANGE.

Fix up some sloppy coding practices:
- Delete redundant declarations. - Add -Wredundant-declarations to Makefile.i386 so they don't come back. - Delete sloppy COMMON-style declarations of uninitialized data in header files. - Add a few prototypes. - Clean up warnings resulting from the above.
NB: ioconf.c will still generate a redundant-declaration warning, which is unavoidable unless somebody volunteers to make `config' smarter.
