- removed linux/atm_stdint.h (linux/types.h has now caught up)
- changed ENI and ZATM driver to use new PCI interface
- net/atm/clip.c no longer uses ether_setup (suggested by Alexey Kuznetsov)
- more header file cleanup (main change: applications should now
#include <atm.h> instead of #include <linux/atm.h>)
- removed -Wmissing-prototypes from Rules.make because of a conflict with
include/linux/byteorder/swab.h
Version 0.35 to 0.36 (23-APR-1998)
====================
Bug fixes
---------
- changed the numeric values of PF/AF_ATMPVC/SVC and SOL_ATM/AAL to avoid
conflicts with other allocations. This breaks binary compatibility with
ATM programs compiled under older kernels
- RESTART ACK was sent with the wrong class when acknowledging the restart of
the indicated virtual channel (fix by Mohsen Souissi)
- RELEASE was retransmitted forever (to avoid having to perform a RESTART),
although it's sufficient to retransmit once and then drop the connection
- esi.c checked the kernel version code without including linux/version.h
- CLIP changes magically fixed hangs on SICGIFCONF (reported by Wayne Salamon)
- atmsigd usually didn't set pvc.sap_family in ISP messages
New features
------------
- added build-time option -DTHOMFLEX to send RESTART when SAAL comes up, which
works around a bug in some Thomson Thomflex 5000 switches (by Mohsen
Souissi)
- atmtcp: new option "-i itf" to request a specific interface number
- the "debug switch" (switch/debug/sw_debug) is now capable of successfully
signaling a UNI 3.x call (see switch/debug/README for details)
Other changes
-------------
- atm_equal can now also compare PVC addresses. The argument type has
therefore been changed from struct sockaddr_atmsvc * to struct sockaddr *
- moved driver-private data from skb->atm.* into skb->cb
- complete redesign of communication between atmarp(8) and atmarpd(8) (now
uses a UNIX domain socket; suggested by Alexey Kuznetsov)
- atmarp -a now also produces correct output if atmarpd is running with -d
- removed clip(8)
- moved atmarp(8) from atm/ip into atm/arpd, removed atm/ip
- /proc/atm/svc shows listening sockets again
- cleaned up a few cases where diag(...,DIAG_FATAL,...) was followed by an
"else" or a "return".
- atmsigd now uses Unix domain sockets (instead of named pipes) to communicate
with non-kernel ISP users (updated test/isp too)
- net/atm/resources.c:atm_dev_register can now be asked to assign a specific
interface number (-1 yields the old behaviour)
Version 0.34 to 0.35 (27-MAR-1998)
====================
Bug fixes
---------
- ilmid compared memcmp results with -1,1, which fails under optimization
(fixed by Damian Gilmurray)
- various fixes and cleanup in how CLIP interacts with the neighbour cache
(spotted by Alexey Kuznetsov)
- Rules.make complained about missing "optprocess" command on some occasions
New features
------------
- upgraded to the 2.1.90 kernel
- added some components for ATM switch control (not properly integrated yet,
so they don't do anything useful at the moment; written by Roman Pletka)
Other changes
-------------
- eliminated various compiler warnings when compiling with glibc2
- removed clip_hard_header (suggested by Alexey Kuznetsov)
Version 0.33 to 0.34 (13-MAR-1998)
====================
Bug fixes
---------
- eni.c didn't include config.h (fix by Pete Wyckoff)
- (yet another) VCC list handling bug (fixed by Heikki Vatiainen)
- kernel also applied idle timeout to CLIP PVCs
- make clean didn't remove test/errnos.inc
- atmsigd errored as_connect and as_accept with as_close instead of as_error
- eni: bandwidth was sometimes reserved for UBR VCs
- eni: checking of bandwidth changes was broken
- eni: error handling after failed bw change checks destroyed the free list
- test/errnos.inc sometimes wasn't generated because of mtime granularity (fix
by Brian Armstrong and Corinne Rosier)
- fixed use of return code of get/put_user and copy_from/to_user
- kernel: fixed a few minor race conditions
- ATM_GETADDR left address list locked on fault
- maximum length of high layer information was 7 bytes instead of 8 for ISO
and User Specific high layer information (reported by Damian Gilmurray)
- some tools didn't include errno.h although they use errno or Exxx
- atmsigd usually accessed deallocated memory when writing traces, which
sometimes led to crashes (reported by Heikki Vatiainen)
- indentation of the first two lines of UNI signaling messages in traces was
missing
- LANE: duplicate data direct connections to entities where we already
have a connection are now forbidden. LES and BUS can now co-reside.
(Reported by Jean-Francois Moine, fixed by Heikki Vatiainen)
- LANE: plugged a file descriptor leak (by Heikki Vatiainen)
- atmsigd.conf.4 incorrectly stated that diagnostics must have a higher
priority than the specified level to get printed (they're also printed if
their priority is equal to that level)
- zatm driver didn't virt_to_bus the back pointer of TX rings, leading to
crash after sending the 32nd PDU of a VCC (reported by Ajay Bakre)
- zatm_feedback sometimes returned with interrupts disabled
- ENI driver didn't treat requests for UBR at link speed as "unlimited" and
allocated one shaper for each such VCC
- atm_async_release_vcc now has its own flag ATM_VF_CLOSE. Overloading
ATM_VF_RELEASED caused hung SVCs under some conditions.
- atmsigd sometimes released listening sockets before kernel completed its
cleanup, yielding warnings and zombies
- atmsigd accessed already deallocated data structures when handling
unparseable signaling messages
New features
------------
- upgraded to the 2.1.79 kernel
- CLIP now handles NETDEV_CHANGE (proposed by Pete Wyckoff; untested)
- various minor signaling changes for operation as switch control
- new device operation proc_read: device drivers can now register in /proc
(e.g. /proc/atm/eni:0)
- added some more BHLI definitions to include/atmsap.h, including draft
mapping of well-known TCP/UDP port numbers
- added support for TIOCOUTQ/TIOCINQ on native ATM
- new library function sap_equal
- added convenience function atmpvc_addr_in_use to linux/atm.h
- major overhaul of "isp", which is now a good tool for signaling regression
tests. See atm/test/README.isp
- LANE can now be compiled as a kernel module (by Heikki Vatiainen)
- new tool debug/svctor.c to torture signaling by setting up and releasing
lots of SVCs (see the source for details)
Other changes
-------------
- cleaned up the copying terms: libraries are now covered by LGPL instead of
GPL and qgen doesn't "taint" the code it generates
- atmarpd: IP addresses are now __u32 instead of unsigned long
- atmarpd: changed printf("... %08x ...",(unsigned long) ptr) to %p ...",ptr
- /proc support now allocates inode numbers dynamically
- added comment to clarify motivation for useless buffer alignment in aread.c
(reported by Jeon Jong Hwan)
- suni.c and uPD98402.c: SONET_GETSTATZ no longer clears the statistics if the
copy faults
- ilmid should now work on any interface (patch by Heikki Vatiainen)
- changed all __uNN of tools to uintNN_t for glibc2-compatibility
- added stdint.h to lib for compatibility with future versions of glibc2
- various other evil hacks in tools to make things compile with glibc2
- the NIC debugging programs ed, encopy, endump, zndump, and znth are no
longer built and installed by default
- for compatibility with POSIX 1003.1g, accept now returns ECONNABORTED
instead of ECONNREFUSED if connection is already gone (proposed by Heikki
Vatiainen)
- listening sockets now return instantly if the signaling demon dies
- various minor LANE updates to track API changes (by Heikki Vatiainen)
- SUNI now also warns if signal is missing at initialization time
- zatm: added work-around for unfair buffer space accounting
- clarified some of atmarpd's diagnostics
- documentation updates
Version 0.32 to 0.33 (19-NOV-1997)
====================
Bug fixes
---------
- SSCOP did poll sequence number comparisons in the (data) sequence number
space, typically leading to periodic SSCOP restarts (reported by Heikki
Vatiainen)
- atmsigd now releases calls on receipt of STATUS with call state 0 (reported
by Heikki Vatiainen)
- qgen tried to print the names of unnamed groups (fix by Simon Leinen)
- make clean in qgen left all the .c and .h files produced by qgen
- minor fixes to signaling message format description (qgen/msg.fmt,
previously qgen/uni*)
- /usr/include/atm.h was calling itself "atmlib" (found by Leena Chandran)
- atmsigd: the address format of the calling party number was used to
determine the format of the called party number in a SETUP message
- added some semicolons to Rules.make for bash 2.0 compatibility (by Tan Chang
Hu and Rolf Kunisch)
- select/poll indicated an exception when a non-blocking connect terminated.
Now it indicates writability, and an error only if the connect failed.
- LES/BUS can now co-exist at the same address (by Heikki Vatiainen)
- fixed race condition between asynchronous release (e.g. on ATMARP idle timer
expiration) and signaling demon response
- fixed a typo "[itf]." instead of "[itf.]" in atmsigd.conf.8
- "ATM drivers" kernel configuration section is no longer a top-level menu
item but it's now under "Network devices"
- sigd_close forgot to purge VCs not connected to devices (e.g. closing ones),
so they hung
- the list of unconnected VCs was sometimes garbled
- atmsigd printed null string for as_itf_notify message name when debugging
- Arequipa: check_aq_vcc also accepted VCs that were already released by
signaling
- ATM_VF_PARTIAL and ATM_VF_BOUND had the same value
- atmaddr still used old calling convention of ATM_GETNAMES
- the atmarpd man page referred to atmarpd as "atmsigd"
- various atmtcp bug fixes
- atm_recvmsg sometimes returned with interrupts disabled (reported by Pete
Wyckoff)
- fixed ttcp_atm dependencies (.depend contains dependencies for "ttcp.o")
- UNI message format: "more" was missing for def_pck_size
- eni/suni didn't compile as modules (fixed by Pete Wyckoff and Ladislav
Lhotka)
- further net/atm/Makefile cleanup
- arequipa_close always left the socket with arequipa_expect enabled. Now it
returns it to the previous state.
- ENI driver was leaking buffer memory on failure of set_tx
- atmarpd didn't print symbolic names of "new" flags (ATF_ARPSRV, etc.)
- ATM ARP server didn't make client entries public (reported by Tom Mahieu)
- drivers/atm/Config.in had extra "endmenu" (fixed by Ladislav Lhotka)
- atmarpd got confused when receiving InARP reply without source ATM address
- atmsigd sometimes didn't stop timers if Q.2963.1 wasn't enabled
- when rejecting a call, the kernel freed the VCC twice
New features
------------
- merged source tree (except Arequipa, single-copy, and various NIC drivers)
with 2.1.65-Linus tree
- qgen can now handle repeated information elements
- added ATM_SETESI[F] ioctl and esi utility (boards without a real ESI in ROM
should now set the default ESI to 0x000000000000)
- new socket option SO_ATMSAP along with struct atm_sap (using a fixed-size
BLLI array instead of the linked list in struct sockaddr_atmsvc)
- added Q.2963.1 PCR modification in signaling and the ENI driver
- aread: new option -c to print received data as characters (similar to od -c)
- new tool test/align to test handling of mis-alignment in NIC drivers
- atmsigd now supports policy restrictions for incoming/outgoing calls (see
atmsigd.conf.4, "policy")
- atmsigd can now also use a pair of named pipes (or, actually, any named
object in the file system) for communicating with the user of signaling
(normally the kernel)
- new tool called "isp" (for "Internal Signaling Protocol") to talk ISP with
atmsigd over named pipes
- new functions sap2text and text2sap to converts SAPs to/from textual
representation, and a sap(7) man page
- new traffic parameter field "pcr" to indicate the desired PCR. min_pcr and
max_pcr can the be used to indicate the acceptable range.
- new function atm_pcr_goal to help drivers to interpret traffic parameters
Other changes
-------------
- removed some more obsolete CLIP-related ioctls
- qgen: simplified generation of engines with a prefix other than "q" or "qd"
- ENI and ZATM drivers now use shareable interrupts
- cleaned up some 32bit-isms in ENI driver
- cleaned up several 32bit-isms in SSCOP (reported by Tan Chang Hu)
- SSCOP: work-arounds for buggy ntohl prototype in some early versions of
glibc (reported by Tan Chang Hu, further explored by David S. Miller and
Richard Henderson)
- started updating the ZATM driver for 2.1 (still crashes under load)
- added missing 2.1 pieces in ENI's SUNI driver
- added __initfunc and __initdata where appropriate
- tools tree now compiles under 0.31 (2.0.25 kernel) and 0.33 (2.1.55 kernel)
- gratuitous improvement of identifier tree allocation in qgen
- the interface number is now optional for sonetdiag (like for atmdiag)
- started implementing the kernel side of point-to-multipoint signaling
support
- /proc/atm/arp now displays "resolving" or "expired" (with the number of
times the entry is referenced) instead of "incomplete".
- moved ATM_MAX_BLLI from linux/atm.h to linux/atmsap.h
- changed ttcp_atm to use SO_ATMSAP (if available) to set BHLI
Note: ttcp_atm previously didn't use a BHLI, so old and new versions of
ttcp_atm don't interoperate.
- updated all other programs using SAPs too, except for LANE
- ENI: failure to allocate a traffic shaper now yields EBUSY instead of EAGAIN
- instead of just complaining, the ENI driver now handles all kinds of
mis-alignment in the TX path properly
- re-implemented send and receive side of Arequipa
- merged qgen/uni3x and qgen/uni40 into msg.fmt
- added missing Q.2931/UNI 4.0 items to qgen/q2931.h and msg.fmt
- also added BLLI L3 H.310 codepoint with related encodings
- various file name and identifier changes to give a more appropriate name
(e.g. "uni" or "call") to something that's never been Q.2931
- added library dependencies
- atmsigd produces more readable and usually more comprehensive debugging
output
- atmsigd.conf.4 now mentions that -d is the debugging output addict's choice
- all programs accepting -l syslog now also accept -l stderr. (This is useful
for atmsigd if atmsigd.conf sets logging to something else.)
- atmsigd now issues ATM_GETADDR ioctls on the signaling socket, not on the
kernel socket
- WARNING: text2qos: "pcr" is no longer a synonym for "max_pcr" !
- text2qos now refuses min_pcr=max
- device driver interface: removed vcc->peek; device drivers now choose their
own allocation strategy (change motivated by bug report from Furquan Ansari)

buffer space allocation
- device driver interface: vcc->push no longer allocates buffer space. This is
now done by the driver, via atm_charge
- updated eni, zatm, and atmtcp to use the new mechanism
- zero padding in eni driver failed due to mis-alignment on some systems
(fixed by Pete Wyckoff)
- various compiler warnings removed (by Pete Wyckoff)
- removed support for pre-AREQUIPA_WORK mechanism
- arequipa close mechanism cleanup
- further cleaned up QOS parameter checking

- zatm: renamed struct zatm_thist to struct zatm_t_hist after wondering
myself what on earth "this t" could be ...
- doc/Makefile now invokes dvips with -o
Version 0.31 to 0.32 (10-JUL-1997)
====================
Bug fixes
---------
- manipulation of local ATM addresses didn't check for permission
New features
------------
- ilmid now supports the system group and a couple of ILMI MIB objects (by
Scott Shumate)
- device and VCC allocation is now dynamic
- E.164 addressing support and corrections to address coding in uni3x/uni40
(by S. A. Wright, T. C. Jepsen, and Z. Zhang)
- support for device de-allocation via per-device operation dev_close
Other changes
-------------
- upgrade to kernel version 2.1.37
- ENI driver cleanup (uses readl/writel, skb_put, etc.)
- socket option handling has changed: optval is now void * (to improve
compile-time type checking) and optlen is int (not int *) in getsockopt
- socket option "names" now encode the level and the size (based on an idea of
Elwyn Davies)
- cleaned up some of the #includes in net/atm/proc.c
- total rewrite of ATMTCP (now the data forwarding is done in user space,
which makes things slower but a lot more flexible)
- separated PDU parsing and printing from SSCOP state machine
- new per-device operation dev_close to shut down devices
- changed a few DIAG_WARNs to DIAG_INFO in ilmid
Removed features
----------------
- polled ATM devices are no longer supported
- CLIP is gone (use ATMARP instead)
- Arequipa and LANE don't work yet (will come back later)
Version 0.30 to 0.31 (22-APR-1997)
====================
Bug fixes
---------
- atmarpd even refused IP address changes by the ATMARP server, which
typically led to the creation of one extra SVC
- ATMARP timeouts were computed at the wrong place (found by Gerald Hanusch)
- aqtest's usage didn't mention the -v option
- some tools used 0x%p instead of %p (which is fine in the kernel, by the way)
- skb_migrate didn't update skb->list
- zeppelin: incurred spurious core dumps on unsuccessful attempts to connect
to LANE servers, ESI parsing from command line seg faulted, obtaining ESI
from NIC left an ATM socket hanging, man page didn't describe all options
(by Marko Kiiskila and Heikki Vatiainen)
Other changes
-------------
- arequipa_close now only returns after the Arequipa connection has been
successfully closed. This allows applications to reliably close and
re-create Arequipa SVCs, e.g. to change the traffic parameters.
- the arequipad operations 3rd party close and synchronization are now handled
inside the kernel and survive arequipad restarts
Version 0.29 to 0.30 (10-APR-1997)
====================
Bug fixes
---------
- atmtcp didn't use vcc->push and therefore got the buffer usage accounting
wrong (fix by Gerald Hanusch)
- when closing a VC, the ENI driver didn't wait until all TX data has really
left the board, which created a close/open race (found by Richard Jones)
- SSCOP sometimes omitted the last element in a STAT PDU (fix - even with
optimization vs. Q.2110 - by Ngo Bach Long)
- atmarpd allowed ARP information to change permanent entries (found by Gerald
Hanusch)
- atmsigd's get_pvc used the maximum SDU size, thereby wasting buffer space
very quickly, which led to signaling problems (reported by Richard Jones and
Rik Wade)
- oops, the BUGS file was always one version number ahead
- ATMARP had a race between packets sent by the remote station and the
ATMARP_MKIP ioctl. This caused the dreaded "unknown hw protocol 0xaaaa"
error. (Finally fixed thanks to a dump provided by Patrick Flynn)
- Arequipa had the same race for AREQUIPA_INCOMING. This probably caused the
occasional "loss" (they were actually kept in vcc->recvq until the
connection was closed) of the first packet(s).
Version 0.28 to 0.29 (4-APR-1997)
====================
Bug fixes
---------
- saal/sscop.c: NORMALIZE macro was weird and broken (fix by Ngo Bach Long)
- InARP queries didn't contain the target ATM address, even if it is known,
which stretches the allowances RFC1577 makes for violating RFC1293 (found
by Juha Heinanen)
- tcp_conn_request: Arequipa modification to MTU size calculation used wrong
socket (fix by Gerald Hanusch)
- kernel ATMARP table handling had some obscure races
- temporary work-around: added A2T_LOCAL when using A2T_NAME in atmsigd and
atmarpd. Before, systems using ANS where the name server is reached via (IP
over) ATM exhibited truly bizarre failure patterns when refreshing ATMARP
entries. (With a lot of help from Juha Heinanen)
- ditto for arequipad, although the effects were less dramatic
- atmarpd: if not using -m, incoming connections for which a valid entry
already existed (e.g. due to manual configuration) were not entered in the
kernel ATMARP table until after the entry timed out for the first time (by
Gerald Hanusch)
- skb data areas are now aligned using skb_reserve instead of directly
tampering with skb->data (and forgetting skb->tail in the process ...)
(found by Uwe Dannowski)
New features
------------
- atmarpd is now automatically notified of IP over ATM interfaces already
existing at startup. This greatly simplifies the atmarpd restart ritual.
(All ATMARP table entries and the default QoS are still lost, though.)
Other changes
-------------
- cleaned up some weird and partially dead code in arpd/arp.c (found by
Gerald Hanusch)
- removed superfluous continue in arp.c:atmarp_setentry
- device-driver specific declarations now reside in
/usr/include/linux/atm_<drv_name>.h, so that disgusting hacks like
#include "/usr/src/linux/..." can be avoided (based on proposal by Uwe
Dannowski)
- updated the list of supported NICs in README and the on-line help
- arpd/atmarpd.8: documented that atmarpd -m may violate RFC1577 in subtle
ways (pointed out by Gerald Hanusch)
- updated MPR usage description to version 1.5 and removed mpr.patch
- removed MEM_DEBUG from the build process (MPR 1.5 initializes itself
automatically)
Version 0.27 to 0.28 (27-MAR-1997)
====================
Bug fixes
---------
- atmarpd restarted timers on as_valid -> as_valid transitions, illegally
delayed necessary refreshes (reported by Juha Heinanen)
- SSCOP cleared POLL timer on IDLE timer expiry (fix by Ngo Bach Long)
- atmsigd didn't initialize "now" soon enough, causing an unnecessary
retransmission of the first BGN PDU (by Ngo Bach Long)
- atmsigd responded to RELEASE COMPLETE in ss_rel_ind with a STATUS instead of
entering ss_wait_close (by Steve Pope)
New features
------------
- new tool aqpvc to declare incoming Arequipa traffic on a PVC to the system
(caveat: removing such a PVC can turn out to be surprisingly difficult)
Other changes
-------------
- removed some useless code in atmarpd's handling of VC disconnects
- removed unused signaling state ss_hold (equivalent to ss_wait_rel)
Version 0.26 to 0.27 (11-MAR-1997)
====================
Bug fixes
---------
- oops, forgot to include atm/lib/rtf2e164_cc.pl in the distribution
- atmsigd's VCI allocation in -N mode was too simplistic and failed after some
signaling activity (reported by Richard Jones)
- atm_connect was rejecting ATM_{VPI,VCI}_ANY
- aq_prev in the list of Arequipa connections wasn't set properly, leading to
random crashes when using Arequipa (found and fixed by Richard Jones, after
weeks of tearing his hair out)
- arequipa_close didn't remove the Arequipa route, which kept the upper layer
protocol connection alive for a rather long time (reported by Richard Jones)
New features
------------
- ilmid enhancements: vastly improved retry mechanism, workaround for a bug in
the ATML Virata switch, -v option for very detailed debug output (Scott
Shumate)
- atmsigd now also accepts the signaling VC as a command line argument
- qos2text appended colon to traffic type even if nothing else followed
- new program debug/aqtest to test Arequipa (based on work by Mehdi Tazi)
Other changes
-------------
- added a few missing NULLs to struct atmdev_ops initialization in various
drivers (this change does not alter any semantics)
- changed printk ...%lx... (unsigned long) ptr to ...%p... ptr at many
places
- removed atm/lib/rtf2cc.pl and atm/lib/cc.inc (they were only used by an
interim version of cc_len)
- atmarp's usage no longer contains lines longer than 80 characters
- added get_logfile() and get_verbosity() to libatm (for ilmid, by Scott
Shumate)
- select() consumed CPU time unnecessarily if testing for one direction while
there's a lot of activity in the other direction (e.g. atmarpd wasted cycles
in select() for each outbound packet while waiting for ARP messages)
- the value of ATM_AAL0 has changed (from zero to 13), so all programs using
AAL0 need to be recompiled
- MAX_ATM_QOS_LEN has changed, so most programs using qos2text need to be
recompiled
- the AAL can now also be set along with the QoS parameters. This approach
should be used instead of specifying it in the socket() call.
- if no AAL is specified, the kernel now defaults to AAL5 (was AAL0)
- updated most demons, tools, and library functions to set the AAL along with
the QoS parameters
Version 0.25 to 0.26 (29-JAN-1997)
====================
Bug fixes
---------
- ATMARP VCCs could stay around forever even after timing out, because the
process was not woken up.
- the ATMARP "fix" in 0.25 introduced an infinite loop. Fixed that one too.
- bit 8 in octets 6 and 7 of BLLI ("ext") were set to 1 instead of 0 when
using ATM_L2_USER/ATM_L3_USER (reported by ukl2@rz.uni-karlsruhe.de)
- qlib added silly offset (which fortunately happened to be zero most of the
time) to dumps of large fields (fixed by Jean-Francois Moine)
- IP over ATM restricted MTU changes to valid Ethernet MTU sizes
- LANE: fixed two bugs that crashed zeppelin when the connection to the
servers failed (by Marko Kiiskila)
New features
------------
- lib/ans.c now properly computes the length of the country prefix of E.164
addresses for reverse lookups (needs file /etc/e164_cc, see USAGE)
- if the new -m option is set, atmarpd now merges incoming calls into the
ATMARP table if the ATM address is known (see atmarpd.8 for details)
- included an RPM spec file (this is still very experimental)
- NICStAR driver now also works with IP over ATM (by Stuart Daniel)
- usage.txt: added description of how to run ATM NICs back-to-back (by Richard
Jones)
Other changes
-------------
- signaling traces now also include SAAL up/down transitions
- qgen no longer (unnecessarily) depends on libatm.a
- started work on letting qgen handle items that appear at more than one
place, e.g. repeated IEs (after an idea by Jean-Francois Moine)
- did some cleanup and added comments to qlib.[ch]
- added -m option to atmarp in config/redhat-4.0/atm.init
- added new make target "filenames" to generate a list of all the files which
are installed
- config/redhat-4.0 now contains an example hosts.atm file and also a Makefile
for more convenient installation
- atmsigd now reads atmsigd.conf before parsing the command-line options,
thereby allowing values set in the file to be superseeded
- atmsigd now also logs the internal reference and the caller's address on
calls establishment
- ilmid: very dirty hack to give switches some time to process ILMI cold start
(by Joseph Evans)
Version 0.24 to 0.25 (20-DEC-1996)
====================
Bug fixes
---------
- net/atm/atmarp.c:idle_timer_check only expired every other entry (reported
by Marko Kiiskila)
New features
------------
- LANE now also supports IPX (SNAP and 802.3; by Marko Kiiskila)
- NICStAR driver now supports VPI != 0 and has configurable settings in
nicstar.h (by Stuart Daniel)
Other changes
-------------
- ENI: TX DMA scratch are is now stored per device. This should allow multiple
NICs to coexist.
Version 0.23 to 0.24 (29-NOV-1996)
====================
Bug fixes
---------
- atm/test/window.c was missing in 0.23
- atm/debug/delay didn't build unless atm/lib headers were already installed
in /usr/include
- atm/debug/znth had undefined return value
- SSCOP: fixed typo (that could probably kill the SSCOP connection in case of
a retransmission); fix by Olivier Bonaventure
- corrected unnecessarily large buffer allocation in zatm.c:pool_index (by
Jonathan Larmour)
- hosts2ans.pl generated reverse addresses for the domain "ATM.INT" instead of
"ATMA.INT"
- atmarpd "forgot" any pre-set QOS when receiving new ARP information for the
respective entry (reported by Gerald Hanusch)
- window scale didn't scale the window sent in the SYNACK packet (reported by
Juan-Antonio Ibanez)
- LANE: better connection failure handling in zeppelin (by Marko Kiiskila)
- LEC kernel timer wasn't restarted when restarting zeppelin (found by Gerald
Hanusch, fixed by Marko Kiiskila)
- LANE: le_flush_request was sent too early when establishing connection (by
Marko Kiiskila)
- zeppelin stopped operation (unwantedly) in random cases when LANE servers
were down (by Marko Kiiskila)

Other changes
-------------
- local variable "link" in atm/debug/delay.c:loop was shadowing "link" system
call
- cleaned up various Makefiles
- qgen: bytes left in qet_space are now more meaningful
- named (ANS) now also starts even if atmsigd is not running and retries to
create the ATM socket in 15 minute intervals until is succeeds (by Marko
Kiiskila)

(by Marko Kiiskila)
Version 0.22 to 0.23 (16-NOV-1996)
====================
Bug fixes
---------
- fixed stupid typos in atm/lib/atmres.h and an unnecessary dependency on
libresolv.a in atm/lib/Makefile (reported by Gerald Hanusch)
- fixed warning about implicit declaration of function bigphysarea_init in
init/main.c
- I think I fixed the SSCOP VR(MR) problems that were first reported by
Edouard Lamboray in '95, then by Heinz Schuerch, and that finally led to a
total SSCOP breakdown (in 0.22) reported by Gerald Hanusch
New features
------------
- integrated the IDT 77201 (NICStAR) driver by Matt Welsh and Stuart Daniel
<stuartd@eecs.umich.edu>. Note that this driver currently only supports
native ATM.
- new throughput and latency benchmark test/window (by Matt Welsh)
Other changes
-------------
- upgrade to kernel version 2.0.25
- changed drivers/atm/eni.c:do_tx:dma to static in order to reduce kernel
stack use (by 480 bytes). Note that this hack may crash systems with more
than one ENI adapter.
- qlib now also complains if changing a field without a fixed list of values
- made a few changes to the native ATM data delivery path to handle some
strangeness required by the IDT driver
Version 0.21 to 0.22 (13-NOV-1996)
====================
Bug fixes
---------
- (dummy) depend target was missing in atm/man (reported by Bernd Wolf)
- net/atm/arequipa.c:make_aq_vcc didn't set ATM_VF_AQINUSE, thereby allowing
race conditions to slip through
- fixed a few potential race conditions when activating Arequipa
- text2qos didn't complain if unit was omitted after multiplier, allowing
misleading settings like pcr=50M (that's 19.2 Gbps)
- SSCOP: took wrong branch if POLL_AFTER_RETRANSMISSION was enabled (fix by
Jonathan Larmour)
- SSCOP: rel_ind for ENDAK and BGREJ PDU in sscop_inconn was sent with "user"
= 1 (must be 0 for "Source := SSCOP")
- initialize_vr_mr now initializes vr_mr to a constant value (instead of
garbage plus constant value)
- atm_recvmsg now ignores msg->msg_name, as it should by POSIX 1003.1g (fix by
Mike Wooten)
- atm_sendmsg now fails with EISCONN instead of with EINVAL if msg->msg_name
is set, as it should by POSIX 1003.1g (reported by Mike Wooten)
- atm_recvmsg and atm_sendmsg now return ENOTCONN if not connected and
EOPNOTSUP if flags are passed, as they should by POSIX 1003.1g
- the QOS zeppelin uses for its connections can now be set with the option -q
- atmarpd didn't include the QOS in PVC entries, so atmarp -a complained about
them
New features
------------
- kernel changes to support tcpdump with LANE (by Marko Kiiskila)
- patch for tcpdump 3.0.4 (installed as tcpdump_atm) to support Classical IP
and LANE (by Marko Kiiskila)

the ATM on Linux distribution
- enhanced text2atm to use ANS if local lookups fail (atm2text will be updated
later)

Other changes
-------------
- changed ATM_VF_AQINUSE to ATM_VF_AQDANG and changed aq_list membership to
be for dangling VCs only
- added the new command-line options to ttcp_atm's online help (finally !)
- atm_sendmsg now returns error codes from the driver's send function
(suggested by Jonathan Larmour)
- text2qos now performs a syntax check if NULL is passed in the qos argument
- various minor LANE cleanup (Marko Kiiskila)
- upgraded to the latest version of t2a.pl
- {A2T,T2A}_REMOTE is obsolete; instead, {A2T,T2A}_LOCAL should be used if
ANS lookups are _not_ desired
Version 0.20 to 0.21 (18-OCT-1996)
====================
Bug fixes
---------
- net/atm/common.c:atm_connect didn't refuse traffic_class == ATM_NONE in both
directions
- include/linux/atmsvc.h:SELECT_TOP_PCR didn't default to ATM_MAX_PCR if
min_pcr == 0 && max_pcr == 0
- debug/delay swallowed one-byte packets
- oops, forgot man/Makefile, so qos.7 wasn't installed
- atmarpd left max_sdu at zero for automatically generated entries
- atmarpd now only uses the default QOS if the traffic type is set in neither
direction
- signaling: if the listen queue was full, new connections were rejected with
as_close instead of as_reject, thereby upsetting atmsigd
- svc_accept didn't adjust the listen queue quota when rejecting incoming
connection requests
- fixed a few bad font selections in atmsigd(8)
New features
------------

linux/atm.h
- removed obsolete keywords from atmsigd.conf language
- atmarp -a now also includes QOS parameters
- UBR now respects txtp.max_pcr if set

Version 0.18 to 0.19 (27-SEP-1996)
====================
Bug fixes
---------
- sscop.c:data_sd had a comparison inversed, so generation of USTAT PDUs was
wrong in some cases (by Juhana Rasanen)
- sigd_enq: accessed vcc->qos without checking for vcc == NULL, causing an
"Oops" in atmaddr
- svc_accept: generated a general protection fault when atmsigd was killed
while a process was waiting for new incoming connections
- atmaddr didn't zero the address structure before calling text2atm
- LANE: fixed usage of kernel timers and LE_ARP_REQUESTs should now get sent
until the entry expires or a response is received (by Marko Kiiskila)
- less compiler warnings from LANE servers (Marko Kiiskila)
- SSCOP: fixed SDU size in AA-RETRIEVE.indication (reported by Heinz Schuerch)
- NULL encapsulation for ATMARP works now (reported by Gerald Hanusch)
- fixed stray EINVAL from get{sock,peer}name on PVCs (reported by Gerald
Hanusch)
- clip now sets max_sdu to RFC1626_MTU+RFC1483LLC_LEN when using LLC/SNAP
encapsulation
- if parsing of a Q.2931 message fails, atmsigd now aborts the call instead of
(stupidly) trying to process the incomplete and probably inconsistent data
- SUNI driver didn't properly mask out unused highest bits of some statistics
counters, thereby yielding absurdly high values
- zatm: changed timing of RX channel closing, so the dreaded "can't close RX
channel" message should be history
- fixed race between Arequipa attachment due to packet reception and closing
of the Arequipa VC
- local address validity check (for ATM_???ADDR) was all wrong (reported by
David Simpson)
- message dumper ignored fatal errors if debugging was not enabled
New features
------------
- man pages for lecs, les, bus, and zeppelin (Marko Kiiskila)
- configuration file name for les and bus can be defined (Marko Kiiskila)

reception timestamps with microsecond resolution (the accuracy is only in
the ms range, though)
- new utility znth (ZeitNet Timer History) to monitor timer synchronization
- LANE now supports up to 4 LEC network interfaces (Marko Kiiskila)
- the Q.2931 message parser now recovers nicely from IE errors, logs the
event, and continues parsing. The higher layers of the signaling stack
don't use this information yet, though.
Other changes
-------------
- Arequipa's BHLI now uses a "vendor-specific application identifier" under
the EPFL OUI
- moved buffer/queue handling from lib/libatmd to saal/, because it is rather
SSCOP-specific anyway
- atm_release_vcc now complains if rx_inuse != 0 when closing (if this ever
happens, it may point out dangerous races with upper layer protocols)
- SO_ATMQOS now issues a warning when using UBR with {min,max}_pcr != 0
- max_sdu is now set by atmarpd to MTU+RFC1483LLC_LEN (atmarp could still
override this, if necessary)
- atmdump: new option -i to display the arrival interval instead of the
absolute time. Also changed the time format to be more readable.
- updated the kernel configuration documentation to indicate that the SMC
ATM Power155 adapters are compatible with the Efficient ENI-155
- atmarpd now deletes the old table file (containing stale information) if
invoked with -d (debug)
Version 0.17 to 0.18 (9-SEP-1996)
====================
Bug fixes
---------
- atmsigd didn't respond to SETUP followed by RELEASE with a RELEASE COMPLETE
- atmsigd now implements incoming call rejection (as_indicate -> as_close)
- kernel now opens the VC before sending the as_accept. This a) allows to
check if the parameters are acceptable, and b) avoids a race condition
between the sender and the local VC open procedure, which frequently led to
loss of the beginning of the first PDU sent on a new connection.
- qdump: _q_parse used the wrong length when dumping variable-length fields,
yielding a fatal internal error
- clip didn't set rxtp.max_sdu
- svc_accept didn't set ATM_VF_HASQOS, so getsockopt SO_ATMQOS didn't work
(by Marko Kiiskila)
- ttcp_atm calculated Mbps as 2^20 bits/sec instead of 10^6, thereby making
all results come out approximately 5% too low (by Fraz Ahmad)
- added $(LDLIBS) to linking of lane/lecs (by Lawrence MacIntyre)
- interface number allocation in clip and atmarp did not check for collision
with the respective other name space
- atmarp's -c option didn't work when omitting the "atm" in the interface name
New features
------------
- new man page: arequipad.8
Other changes
-------------
- simplified the internal signaling protocol by adding the as_reject message
(sent by kernel in response to as_indicate; not acknowledged by demon)
- packets received from Arequipa are no longer forwarded to other hosts
- further ilmid improvements to use RSTADDR less frequently (by Gerald
Hanusch; with a slight modification)
Version 0.16 to 0.17 (2-SEP-1996)
====================
Bug fixes
---------
- lib/diag.c didn't fflush when logging to a file

- make spotless didn't know about new $(*PGMS) targets
- atmsigd: fixed memory leak when sending messages to the kernel
- atmarpd: fixed memory leak when sending messages to the network
- atmsigd: didn't send final as_close when kernel closed connection
immediately after requesting it (as_connect)
- several minor corrections
New features
------------
- added make target "uninstall" to remove all files installed by
make install
- atmsigd has two new options: -D dump_dir to set the dump directory and
-t trace_length to set the length of the trace buffer
- wrote a few man pages: atmarp.8, atmarpd.8, atmsigd.8, atmsigd.conf.4
- added automatic support for memory debugging if MPR is installed (and
included a patch to make MPR 1.1 work with ELF). atmarpd and atmsigd
currently use this feature.
Other changes
-------------
- changed "class" to "traffic_class" everywhere
- make install is now implemented in a more elegant way
- q.dump is now much better at finding symbolic names for numbers
- q.dump no longer prints zero-length fields
- qgen no longer includes constructor "microcode" in dumper
- atmarp now gives more informative error messages on ioctl failure
- removed obsolete ioctls SIOCGIFATMADDR and SIOCSIFATMADDR
- added hack to allow ilmid to be less hostile to locally configured addresses
(by Gerald Hanusch; with slight modifications)
- atmarpd now automatically sets ATF_PERM of PVC entries with NULL
encapsulation
Version 0.15 to 0.16 (29-AUG-1996)
====================
Bug fixes
---------
- fixed an "unterminated character constant" warning by CPP in qgen/uni3x
- atm/sigd/q2931.c always tried to read the Cause IE of RELEASE COMPLETE
messages even if it wasn't included
- LANE: fixed buffer allocation and VCC timeouts (Marko Kiiskila)
- LANE: when connecting directly to LES, name of the ELAN was not set
properly (discoverd by Gerald Hanusch; fixed by Marko Kiiskila)
- LANE, ATMARP, signaling: control sockets didn't account for messages sent
back from demons (fixed by Marko Kiiskila)
- permanent ATMARP entries for SVCs were ignored if no ATMARP server was
configured (reported by Gerald Hanusch)
- atmarp option "temp" mis-spelled as "term" (fixed by Gerald Hanusch)
- forgot to undo experimental rcvbuf/sndbuf change to unsigned long
- make modules didn't generate ATM modules
- atmtcp_attach_hook wasn't defined when compiling ATMTCP as a module
- ATM patch set dev->ip_atm to ether_arp in net/ppp.c and net/eql.c, so they
failed to work as modules
New features
------------

(Marko Kiiskila)
- LANE: major cleanup of zeppelin code (Marko Kiiskila)
- improved loadable module support for eni and zatm (i.e. loading works now)
- the message dumper can now be linked to programs that also use the
compilation/parsing functions
Version 0.14 to 0.15 (31-JUL-1996)
====================
Bug fixes
---------
- zatm: fixed traffic shaper settings for UBR (with a little help from Joern
Wohlrab)
- atmsigd compilation didn't use the same UNI version configuration as qgen
- field "class" in struct atm_traform broke compilation of ATM applications
written in C++, so it has been renamed to "traffic_class" (reported by
Furquan Ansari)
- AAL parameters IE wasn't included in CONNECT, which violated RFC1755
(discovered by Robert Olsson)
- zatm: removed broken sanity check for in-sequence skb delivery on RX
- clip didn't have clip_open function, so SIOCSIFFLAGS on the interface failed
with ENODEV
- single-copy compiles again
- zatm: driver doesn't pretend any longer to support single-copy (but
single-copy will come back later)
- QOS IE was sent with the wrong coding standard when using UNI 3.1 (with help
from Fraz Ahmad)
- zatm: forgot to remove some debugging code (around ZATM_TUNE)
- qlib.c didn't zero the length array, leading to (rare) "not enough space"
errors from QMSG (actually, the "break" mechanism seems to be flaky - will
have to check)
- fixed Arequipa race condition when the upper layer protocol and signaling
decided to close the SVC at the same time
- alloc_tx used to return NULL in out of memory conditions, thereby possibly
hanging atm_sendmsg
New features
------------
- ttcp_atm now also accepts names with -p
- (finally !) added send/receive buffer limits and cleaned up the use of
vcc->[rt]x_{inuse,quota}
- added mkdiff script for automatic generation of diffs
- Arequipa now works for PVCs too (but arequipad is now required for any
use of Arequipa, not only for incoming connections)
Other changes
-------------
- atm/atm-<version>.patch is now called atm/atm.patch (to make the diffs more
useful)
- the maximum SDU size is now checked in net/atm/common.c:adjust_tp
- text2atm/atm2text now accepts/generates E.164 addresses with a leading +
sign, as required by ANS (atm95-1532)

- internal signaling protocol: split as_establish into as_connect and
as_accept
- internal signaling prococol: as_close.reply no longer contains positive
numbers
- internal signaling prococol: as_bind now also carries the AAL type
- atmsigd: now also checks the AAL type in as_bind messages
- kernel signaling: a few minor changes
- STANDARDS (i.e. UNI version) configuration option has been moved from
atm/qgen/Makefile to atm/Rules.make
- atmsigd's startup message now gives more useful indication of which UNI
version(s) it supports
- signaling no longer uses sa[sp]_[rt]xtp, so ...
- sa[sp]_[rt]xtp is gone
- removed atm/sigd/svc.c from the distribution. We now have many other tools
for testing SVCs, so it's superfluous.
- atmarpd: revalidation is now less frequent (use -DFREQUENT_REVAL for
the faster timeout)
- ioctl CLIP_PVC now returns the number of the new interface and clip prints
its name to standard output (like atmarp -c)
- clip now issues the CLIP_PVC ioctl after binding, which avoids wasting
interface numbers on failed setup attempts
- atmsigd -d now sets the debug level for qgen and SSCOP to DIAG_INFO, and
doesn't set q_dump
- zatm: added protection against I > M
- atm_peek_aal5 now only aligns to page boundaries for pdu_size >= PAGE_SIZE
- eni driver now spits out CRC error messages at most every other second
- zatm driver now repeats RX error messages at most every other second
- ttcp_atm now sleeps for a second after setting up an SVC, because the
switch seems to lag behind (need to examine this further)
- moved SAAL from sigd/ to saal/ (for sharing with UNI 4.0 signaling)
- Arequipa sockets are now closed via arequipad instead of via atmsigd (new
ioctls AREQUIPA_CTRL and AREQUIPA_CLS3RD)
- various minor changes
Version 0.13 to 0.14 (19-JUL-1996)
====================
Bug fixes
---------
- LANE: reaction to LE_ARP_RESPONSE's wasn't always correct
- LANE: compiler warnings fixed
- LANE: comparing ATM addresses in checking whether connection is formed was
wrong
- zntune didn't divide by 1024 when displaying the "k"
- .depend wasn't deleted by make spotless
- ATM_GETSTAT and ATM_GETSTATZ used wrong argument type for coding ioctl
number. WARNING: programs using ATM_GETSTAT{,Z} need to be recompiled.
- requests to set up SVCs with ATM_NONE in both directions are now caught by
svc_connect (used to yield an invalid SETUP message)
- signaling: fixed connection identifier setting when acting as network side
(fix by Elwyn B Davies)
- ATMARP server ARP entries were undeletable
- atmarp showed wrong argument in error message when given an invalid ATM
address
- zatm: do_tx left interrupts turned off when returning with RING_BUSY
- LANE ARP hash table handling bugs fixed
- atmarp: act_create is now only sent on interface creation
- atmarp: act_down is now only sent once per transition
- demon control SVCs are no longer closed when atmsigd dies (new VCC flag
ATM_VF_META)
- netdevice notifier is now properly unregistered when atmarpd goes down
(not doing so caused endless loop in kernel on atmarpd restart)
- sigd_enq{_atomic} never calls schedule()
- atmsigd no longer "forgets" to bring up ARP server SVC before sending an
InARP
- atmarpd no longer dies with "timer in state 3" when the ARP server becomes
unreachable
- atm/atmarp.c: clip_create() now refuses creation of already existing
interface
- Documentation/Configure.help gave an obsolete URL for CONFIG_AREQUIPA
and doc/usage.tex also mentioned the old file name
- Arequipa didn't work in the outbound direction for TCP, because
net/ipv4/tcp.c was missing in the kernel patch
- drivers/atm/eni.c:foo raced with initialization of eni_boards if the
board lost the signal _immediately_ after being initialized
- atmarpd: fixed a few uninitialized entry->timer pointers (discovered by
Gerald Hanusch)
- atmarpd: arps entry should no longer get stuck in as_resolv
New features
------------
- compiles on SparcLinux too (but only atmtcp works)
Other changes
-------------
- upgrade to kernel version 2.0.0
- BHLI matching changed: SAPs without BHLI are now incompatible with calls
that specify a BHLI
- LANE: interface stays up when zeppelin dies -> possibility for
wrapper script around zeppelin
- LANE: LUNI interoperability test (ATM Forum/96-0805) is now followed
in setting ELAN name in LE_CONFIG_RESPONSE and LE_JOIN_RESPONSE,
there is also a delay of 1 second before sending LE_CONFIG_REQUEST and
LE_JOIN_REQUEST. This allows 'slow' LE servers to catch up.
- LANE: no longer uses sa[sp]_[rt]xtp
- LANE: now adjusts better to ATM address changes
- zeppelin: new option -m to select debugging output
- updated aping, aread, awrite, br, bw, atmdump, ilmid, atmarp, clip, atmarpd,

Anerousis)
- awrite: fixed txtp.max_sdu calculation in awrite (was using uninitialized
variable "offset")
- atmarpd: IP interface removal now has the desired effect (used to do
nothing)
- atmarpd: now reports and ignores unexpected interface transitions
- added sigd_enq_atomic for atomic sigd_enq (so that non-Arequipa SVCs can
still use the "safe" but non-atomic version)
- made SIOCGIF* failures in atmarpd non-fatal (itf.c:itf_up was handling them
anyway)
- moved Arequipa-specific code from net/atm/clip.c to net/atm/arequipa.c, and
put code common to CLIP, Arequipa, and - to a lesser extent - ATMARP into
net/atm/ipcommon.[ch]
- Arequipa can now be complied without CLIP
- various minor documentation changes
- moved ATM device initialization from net/atm/pvc.c to drivers/block/genhd.c,
where most other devices are initialized too
- preparation for new binary locations: tools build process now knows about
four types of programs: for booting, for system use, for users, and for
internal use during build
- make install now hides the for loops
- non-user binaries are now installed in /usr/local/sbin
- struct atm_iobuf.buffer is now of type void * (was int*). Also,
ATM_GETNAMES now returns the length in bytes in that field.

====================
Bug fixes
---------
- BHLI type used the ATM_HL_* values (which are off by one) in qgen/uni3x
- atmarpd ended up in a tight select-accept loop if atmsigd went away

prototyped by Jean-Michel Pittet
- new traffic class ATM_ANYCLASS to accept incoming SVCs without looking at
the traffic parameters

====================
Bug fixes
---------
- atm/lib/Makefile: had to comment out PGMS=test
- distribution didn't include atm/doc/usage.txt
- patch didn't include arch/i386/config.in
- return 0; was missing at the end of net/atm/mmuio.c:mmu_step
- atm/ilmid didn't install into INSTBIN; also made some other Makefile
changes
- read() returned garbage instead of error when network drops connections
- POLL_AFTER_RETRANSMISSION in SSCOP didn't even compile
- SVCs: bind to wildcard addresses should now work even if no local address
is known yet
- make clean in atm/qgen left some dirt
- ATM drivers didn't free skbs when detecting an error in TX direction

====================
Bug fixes
---------

to some minor memory leaks)
- various major fixes for CBR SVCs
- RELEASE was signaled for SVCs before all data was sent
- single copy tried to access mem_map with user space addresses, leading to
crashes or worse
- zatm: sleep_on was racing with TX completion in close_tx, leading to hangs

user
- atmtcp: fixed handling of VPI/VCI <= 0 for setsockopt(SO_CIRANGE)
- eni and zn driver had static UBR shaper pointer, making it difficult to have
more than one such device per system
- eni driver initialization didn't work properly in systems with ASIC Tonga
- suni.[ch]: confused MC (Master Config) and MCT (Master ConTrol) registers

as_itf_notify)
Other changes
-------------
- known bugs are now listed in a file called BUGS
- all utility programs (aread, awrite, atmdump, br, bw, clip, ttcp) now use
the notation [itf.]vpi.vci for PVCs (was itf vpi vci , except for ttcp,

- all ioctl values have changed
Note: most programs have to be recompiled because of this
- sigd and arpd now register their control sockets via ioctls

in eni driver
Other changes
-------------
- upgraded to kernel version 1.3.24
- changed the distribution directory structure (programs are now in maint/,
test/, ip/, debug/, and sigd/, see INSTALL)
- ATM interfaces are no longer named, only numbered. This affects the
ATM_GETNAMES ioctl, all ioctls using struct atmif_sioc, the usage of atmdiag
and sonetdiag, and various diagnostic kernel messages.
- ATM socket state is now recorded in field "flags" (this also replaces the
SVC fields "released", "registered", and "state")
- added #ifdef __KERNEL__ to some header files
- added "int immed" argument to send_oam

&ATM_SD(sock)->sleep)
- ENI driver did allow binding to VPI/VCI already in use
- ENI driver now properly handles PDUs with CRC errors
- ENI driver had race condition when discarding PDUs causing new PDUs to be
shifted in adapter memory by one word (which confused the driver quite a
bit)
- ENI driver now enables VC _after_ setting all pointers (caused crashes if
data was already coming in while opening VC)
- various bugs fixes related to SVC sockets
- fixed GPF (in kernel) when running atmdiag without arguments
- atmdiag now left-adjusts interface names

"MMF" and "UTP" instead of "UTOPIA")
- some redesign of the protocol used for signaling between kernel and demon
- disabled "Grr, servicing VCC twice" message in ENI driver

must provide it
Version 0.1 to 0.2 (15-AUG-1995)
==================
Bug fixes
---------
- VCC family field is now correctly set to protocol family in
common.c:atm_create (was pvc.c:pvc_create). With protocol set to zero,
this created all types of strange problems, because the family field
is used to indicate whether an VCC slot is busy/free.
- fixed race condition in common.c:atm_read (reader might have blocked
even if data is ready)
- fixed dereferencing of uninitialized skb->dev pointer in
clip.c:atm_push_clip
- SIOCSIFATMTCP now refuses to attach the same socket twice
- zatm.c: fixed setting of the VPI/VCI mask

- added support for ATM_{VPI,VCI}_ANY
- SIOCSIFATMTCP now returns the interface number and atmtcp(8) prints it
- wrote atmtcp man page
- added kernel part of SVC support
Other changes
-------------
- common.c: only root is now allowed to bind to reserved VCIs
- Classical IP interfaces are now removed by downing by ifconfig; clip(8)
returns immediately

- new field (type) in struct atm_dev to indicate device type
- moved getsockopt(SO_CIRANGE) to common.c (removed atmtcp's own version)
- added ci_range to struct atm_dev (and removed it from atmtcp's private
structure)
- added code to read the ESI to zatm.c (but that code doesn't seem to work
yet)
