57cb697829 Partially roll back a revision which changed the error code being returned
by getaudit(2).  Some applications such has su, id will interpret E2BIG as
requiring the use of getaudit_addr(2) to pull extended audit state (ip6)
from the kernel.

This change un-breaks the ABI when auditing has been activated on a system
and the users are logged in via ip6.

This is a RELENG_7_1 candidate.

d85d1b90b5 Major overhaul:
o eliminate private state indexed by 802.11 rate codes; use the hal's
  rate tables directly to get the same info
o calculate a mask of operational rates to optimize lookups and checks
  (instead of using for loops and similar)
o optimize size bin operations
o ignore rates marked as "do not use" in the hal phy tables
o fix bug that caused upshifting to break in 11g once the rate dropped
  below 11Mb/s
o add more intelligent multi-rate tx schedules
o add support for 1/2 and 1/4 width channels
o add dev.ath.X.sample_stats sysctl to dump runtime statistics to the console
  (needs to go up to a user app)
o export more tuning knobs via sysctls (still a couple of magic constants)

83dc2280ce WIP kinfo_file/kinfo_vmmentry tweaks. The idea:
1) to get the 32 and 64 bit versions in sync so that no shims are needed,
Valgrind in particular excercises this.  and:
2) reduce the size of the copyout.  On large processes this turns out to
be a huge problem.  Valgrind also suffers from this since it needs to do
this in a context that can't malloc. I want to pack the records.
3) Add new types..  'tell me about fd N' and 'tell me about addr N'.

7a6d0a128f Regen after jail support was added in r185435. 2008-11-29 14:34:30 +00:00
bz
d2730d5b27 MFp4:
Bring in updated jail support from bz_jail branch.

This enhances the current jail implementation to permit multiple
addresses per jail. In addtion to IPv4, IPv6 is supported as well.
Due to updated checks it is even possible to have jails without
an IP address at all, which basically gives one a chroot with
restricted process view, no networking,..

SCTP support was updated and supports IPv6 in jails as well.

Cpuset support permits jails to be bound to specific processor
sets after creation.

Jails can have an unrestricted (no duplicate protection, etc.) name
in addition to the hostname. The jail name cannot be changed from
within a jail and is considered to be used for management purposes
or as audit-token in the future.

DDB 'show jails' command was added to aid debugging.

Proper compat support permits 32bit jail binaries to be used on 64bit
systems to manage jails. Also backward compatibility was preserved where
possible: for jail v1 syscalls, as well as with user space management
utilities.

Both jail as well as prison version were updated for the new features.
A gap was intentionally left as the intermediate versions had been
used by various patches floating around the last years.

Bump __FreeBSD_version for the afore mentioned and in kernel changes.

Special thanks to:
- Pawel Jakub Dawidek (pjd) for his multi-IPv4 patches
  and Olivier Houchard (cognet) for initial single-IPv6 patches.
- Jeff Roberson (jeff) and Randall Stewart (rrs) for their
  help, ideas and review on cpuset and SCTP support.
- Robert Watson (rwatson) for lots and lots of help, discussions,
  suggestions and review of most of the patch at various stages.
- John Baldwin (jhb) for his help.
- Simon L. Nielsen (simon) as early adopter testing changes
  on cluster machines as well as all the testers and people
  who provided feedback the last months on freebsd-jail and
  other channels.

bf74bb2e16 In the nfsrv_fhtovp(), after the vfs_getvfs() function found the pointer
to the fs, but before a vnode on the fs is locked, unmount may free fs
structures, causing access to destroyed data and freed memory.

Introduce a vfs_busymp() function that looks up and busies found
fs while mountlist_mtx is held. Use it in nfsrv_fhtovp() and in the
implementation of the handle syscalls.

Two other uses of the vfs_getvfs() in the vfs_subr.c, namely in
sysctl_vfs_ctl and vfs_getnewfsid seems to be ok. In particular,
sysctl_vfs_ctl is protected by Giant by being a non-sleeping sysctl
handler, that prevents Giant-locked unmount code to interfere with it.

355c41a8e4 Fix matching of message queues by name.
The mqfs_search() routine uses strncmp() to match message queue objects
by name. This is because it can be called from environments where the
file name is not null terminated (the VFS for example).

Unfortunately it doesn't compare the lengths of the message queue names,
which means if a system has "Queue12345", the name "Queue" will also
match.

I noticed this when a student of mine handed in an exercise using
message queues with names "Queue2" and "Queue".

aa86a7c59e - Add support for PMCs in Intel CPUs of Family 6, model 0xE (Core Solo
and Core Duo), models 0xF (Core2), model 0x17 (Core2Extreme) and
  model 0x1C (Atom).

  In these CPUs, the actual numbers, kinds and widths of PMCs present
  need to queried at run time.  Support for specific "architectural"
  events also needs to be queried at run time.

  Model 0xE CPUs support programmable PMCs, subsequent CPUs
  additionally support "fixed-function" counters.

- Use event names that are close to vendor documentation, taking in
  account that:
  - events with identical semantics on two or more CPUs in this family
    can have differing names in vendor documentation,
  - identical vendor event names may map to differing events across
    CPUs,
  - each type of CPU supports a different subset of measurable
    events.

  Fixed-function and programmable counters both use the same vendor
  names for events.  The use of a class name prefix ("iaf-" or
  "iap-" respectively) permits these to be distinguished.

- In libpmc, refactor pmc_name_of_event() into a public interface
  and an internal helper function, for use by log handling code.

- Minor code tweaks: staticize a global, freshen a few comments.

5b628c272e Add basic WOL support for 82550/82551/82558 and 82559 based
controllers. ICH based controllers are treated as 82559. 82557,
earlier revision of 82558 and 82559ER have no WOL capability.
 o WOL support requires help of a firmware so add check whether
   hardware is capable of handling magic frames by reading EEPROM.
 o Enable accepting WOL frames only when hardware is about to
   suspend or shutdown. Previously fxp(4) used to allow receipt of
   magic frame under normal operation mode which could cause
   hardware hang if magic frame is received by hardware. Datasheet
   clearly states driver should not allow WOL frames under normal
   operation mode.
 o Disable WOL frame reception in device attach so have fxp(4)
   immunize against system hang which can be triggered by magic
   packets when the hardware is not in fully initialized state.
 o Don't reset all hardware configuration data in fxp_stop()
   otherwise important configuration data is lost and this would
   reset WOL configuration to default state which in turn cause
   hardware hang on receipt of magic frames. To fix the issue,
   preserve hardware configuration data by issuing a selective
   reset.
 o Explicitly disable interrupts after issuing selective reset as
   reset may unmask interrupts.

6d7402ae81 Pass the pointer to the selected partition in %si to the next stage
boot code. The bug was introduced in rev.1.13, and went unnoticed
because FreeBSD's boot1 does not use it, but other systems might.

(I have been struggling for almost a full day trying to figure out
why a syslinux'ed partition would not boot when started with the
FreeBSD /boot/boot0, only to realize that the bug was ours!)

The space for the two extra bytes (push %si and pop %si) is reclaimed
by removing an extra CRLF that is printed before booting.

The bug is not a major one but if there is time it might be a good
thing to merge it into the upcoming releases.

2e91108b54 Implement TSO for 82550/82551 controllers.
o Configure controller to use dynamic TBD as TSO requires that
   operation mode.
 o Add a dummy TBD to tx_cb_u as TSO can access one more TBD in TSO
   operation.
 o Increase a DMA segment size to 4096 to hold a full IP segment
   with link layer header.
 o Unlike other TSO capable controllers, 82550/82551 does not
   modify the first IP packet in TSO operation so driver should
   create an IP packet with proper header. Subsequent IP packets
   are generated from the header information in the first IP packet
   header. Likewise pseudo checksum also should be computed by
   driver for the first packet.
 o TSO requires one more TBD to hold total TCP payload. To make
   code simple for TSO/non-TSO case, increase the index of the
   first available TBD array.
 o Remove KASSERT that checks the size of a DMA segment should be
   less than or equal to MCLBYTES as it's no longer valid in TSO.
 o Tx threshold and number of TBDs field is used to store MSS in
   TSO. So don't set the Tx threshold in TSO case.

fee7af0f4b Implement Rx checksum offload for 82559 or later controllers.
82559 or later controllers added simple checksum calculation logic
in RU. For backward compatibility the computed checksum is appended
at the end of the data posted to Rx buffer. This type of simple
checksum calculation support had been used on several vendors such
as Sun HME/GEM, SysKonnect GENESIS and Marvell Yukon controllers.
Because this type of checksum offload support requires parsing of
received frame and pseudo checksum calculation with software
routine it still consumes more CPU cycles than that of full-fledged
checksum offload controller. But it's still better than software
checksum calculation.

a0562881c5 o Introduce a new function, fxp_new_rfabuf which allocates a new
Rx buffer and loads DMA map. Also add a function
   fxp_discard_rfabuf that handles reusing Rx buffer/DMA map. With
   this change fxp_add_rfabuf just handles appending a new RFA to
   existing chain.
 o Initialize mbuf length in fxp_new_rfabuf.
 o Don't reset rnr and have fxp(4) handle received frames even if
   it couldn't allocate new Rx buffer. This will make fxp(4) reload
   updated RFA under rnr case. The rnr would still be reset to 0 if
   polling is active and fxp(4) processed number of allowed Rx
   events.
 o Update if_iqdrops if fxp(4) couldn't allocate Rx buffer.

Previously fxp(4) used to try to reuse Rx buffer when new buffer
allocation is failed. But fxp(4) didn't take into account loaded
DMA map such that the same DMA map was loaded again without
unloading the map. There is no reason to unload the loaded map and
reload the same map again, just reusing the map is enough. I
believe the spare DMA map in softc was introduced to implement this
behaviour. Also fxp(4) used to stop Rx processing if once Rx buffer
allocation or DMA map load fails which in turn resulted in losing
incoming frames under heavy network load. With this change fxp(4)
should survive from resource shortage condition.

c8de3cce1a - Allow fxp_encap() enqueue failed transmissions and set
IFF_DRV_OACTIVE to note resource shortage to upper stack.
- Don't count number of mbuf chains. Default 32 DMA segments for a
  frame is enough for most cases. If bus_dmamap_mbuf_sg fails use
  m_collapse(9) to collapse the mbuf chain instead of relying on
  expensive m_defrag(9).
- Move bpf handling to fxp_start_body() which is supposed to be
  more appropriate place.
- Always arm watchdog timer whenever a new Tx request is made.
  Previously fxp(4) used to arm watchdog timer only when
  FXP_CXINT_THRESH-th Tx request is made. Because fxp(4) does not
  rely on Tx interrupt to reclaim transmitted mbufs it's better to
  arm watchdog timer to detect potential lockups.
- Add more aggresive Tx buffer reclaiming in fxp_start_body to make
  room for new Tx requests. Since fxp(4) does not request Tx
  completion interrupt for every frames it's necessary to clean
  TXCBs in advance to saturate link.
- Make fxp(4) try to start more packets transmitting regardless of
  interrupt type in fxp_intr_body.

f9fbe622cf - improve AL2230 RF handling when the device type is zd1211. After this
patch the RX/TX performance becomes about 17~18 Mbps comparing with
  the previous whose values were RX 7~8Mbps and TX 13~14Mbps.
- improve AL2230 RF handling in zd1211b
- support AL2230S RF that PV2000 is renamed to AL2230S
- use register ZYD_CR244, ZYD_CR243, ZYD_CR242 when the driver writes
  values on RF.  This routine is more faster than the original one
- use private TX lock to avoid LOR at zyd_raw_xmit()
- increase TX slots from 1 to 5
- needs to set the channel at IEEE80211_S_AUTH not IEEE80211_S_RUN
- detailed error handling.  In previous the next command was sent to the
  device even if there was errors
- setting ZYD_MAC_RX_THRESHOLD value should be different between 1211
  and 1211b
- only try to stop the device at zyd_init_locked() if the device is
  UPed
- do not use MTX_RECURSE
- do not try to grap Giant lock when the channel is changing
- move the device initialization routines from zyd_attach to zyd_init to
  give a device full-reset chance to the driver.
- code cleanup at zyd_raw_xmit()
- simplify zyd_attach() routines
- resort functions and clean up variables
- DPRINTF style change.

371d0216fb Busy ufs filesystem around block of code that does ".." lookup. Since
mnt_lock is before lock of any vnode on the mp, it uses LK_NOWAIT. Since
MNTK_UNMOUNT may be transient, pdp lock is dropped when vfs_busy()
failed, and operation is retried after some time. This way, ffs_vget()
is not called on the mp that may be in the process of being destroyed by
unmount.

Check for the VI_DOOMED flag on pdp after its lock is reacquired, to
better detect some situations where directory containing ".."
entry is removed during the lookup.

1c382cbab0 - According to OpenSolaris, CDMA flushing/syncing for Tomatillos
and XMITS has to be basically done in the same manner as for
  the Sabres, i.e. only for devices behind PCI-PCI-bridges and
  after a PIO read on the far side of the farest PCI-PCI-bridge.
  Given that the Tomatillo documentation mentions no difference
  to the Schizo bridges in this regard and this is also still
  part of the procedure described Schizo documentation this
  seems about right so adjust accordingly (the unconditional
  CDMA flushing/syncing previously done was based on how Linux
  behaves).
- Implement CDMA flushing/syncing for Schizo version >= 5,
  which requires the workaround described in Schizo Errata I-23.
  According to Schizo Errata I-13 it's just unusable with
  version < 5 though. [1]
- Don't register the Schizo streaming buffer for now until it's
  usage is sorted out according to the erratas.
- Register our interrupt filters with the revived INTR_FAST so
  they these interrupts can even interrupt filters of device
  drivers as necessary.
- Remove the comment regarding lack of newbus'ified bus_dma(9)
  as being able to associate a DMA tag with a device would
  allow to implement CDMA flushing/syncing in bus_dmamap_sync(9)
  but that would totally kill performance. Given that for devices
  not behind a PCI-PCI bridge the host-to-PCI bridges also only
  do CDMA flushing/syncing based on interrupts there's no
  additional disadvantage for polling(4) callbacks in the case
  schizo(4) has to do the CDMA flushing/syncing but rather a
  general problem.

8c1c552ad2 As reported in kern/118222, pxeboot in RELENG7 (and presumably
above) exhibits some misbehaviours on machines with AMD64 CPUs,
which at least in some cases I have tracked down to a heap overflow.

It is unclear whether it depends on the CPU or on the pxe bios
itself which may use more memory on AMD machines.

Noticeably a pxeboot compiled from 6.x sources works fine on all
machines I have tried so far, while a pxeboot compiled from 7.x
sources does not.

This patch is a first step in reducing the amount of memory used
while processing the configuration files read by the loader at boot
(some of them are quite large, 1700+ lines), and it does so by:
+ moving a buffer to static memory instead of allocating in the heap;
+ skipping empty lines;
+ reducing the amount of memory used for line descriptors;

Unfortunately there are several changes between 6.x and above,
affecting the compiler, the loader code itself, and libstand,
and it is not so straightforward to
These changes fix the behaviour on one motherboard with a
single-core AMD cpu, but are still not enough e.g on an Asus
M2N-VM (with a dual-core CPU).

I need to investigate the problem a bit more before figuring
out what should be committed to RELENG_7

815d52c5df Change the initialization methodology for global variables scheduled
for virtualization.

Instead of initializing the affected global variables at instatiation,
assign initial values to them in initializer functions.  As a rule,
initialization at instatiation for such variables should never be
introduced again from now on.  Furthermore, enclose all instantiations
of such global variables in #ifdef VIMAGE_GLOBALS blocks.

Essentialy, this change should have zero functional impact.  In the next
phase of merging network stack virtualization infrastructure from
p4/vimage branch, the new initialization methology will allow us to
switch between using global variables and their counterparts residing in
virtualization containers with minimum code churn, and in the long run
allow us to intialize multiple instances of such container structures.

- An "at" hint now reserves a device name.
- A new BUS_HINT_DEVICE_UNIT method is added to the bus interface.  When

  via an "at" hint.
- Implement BUS_HINT_DEVICE_UNIT() for the acpi(4) and isa(4) bus drivers.
  Both of these busses implement this by comparing the resources for a
  given hint device with the resources enumerated by ACPI/PnPBIOS and
  wire a unit if the hint resources are a subset of the "real" resources.

- Delegated Administration

	Allows regular users to perform ZFS operations, like file system
	creation, snapshot creation, etc.

- L2ARC

	Level 2 cache for ZFS - allows to use additional disks for cache.
	Huge performance improvements mostly for random read of mostly
	static content.

- slog

- vfs.zfs.super_owner

	Allows regular users to perform privileged operations on files stored
	on ZFS file systems owned by him. Very careful with this one.

- chflags(2)

	Not all the flags are supported. This still needs work.

- ZFSBoot

	Support to boot off of ZFS pool. Not finished, AFAIK.

	Submitted by:	dfr

- Snapshot properties

- New failure modes

	Before if write requested failed, system paniced. Now one
	can select from one of three failure modes:
	- panic - panic on write error
	- wait - wait for disk to reappear
	- continue - serve read requests if possible, block write requests

- Refquota, refreservation properties

	Just quota and reservation properties, but don't count space consumed
	by children file systems, clones and snapshots.

- Sparse volumes

	ZVOLs that don't reserve space in the pool.

- External attributes

	Compatible with extattr(2).

- NFSv4-ACLs

	Not sure about the status, might not be complete yet.

(USIII+) in comparison to the existing spitfire versions or were
even slightly slower (USIIIi) though, so they aren't committed
for now.
The basic problem leading to the VIS-based copy/zero functions
being initially disabled for cheetah-class CPUs was solved by
letting cheetah_init() clear DCR_IFPOE.

ed798111a5 Micro-optimize spitfire_block_{copy,zero}():
- Predict the loop as taken as it's more likely that there's still
  data to copy and memory to zero respectively.
- Don't waste the delay slot.
