Netatalk 2.2.0

The Netatalk development team is proud to announce version 2.2.0 of the Netatalk File Sharing suite. This is the first stable release of the new 2.2 series. Earyl adopters are encouraged to upgrade their systems to 2.2.0.

Netatalk is a freely-available Open Source AFP fileserver. It also provides a kernel level implementation of the AppleTalk Protocol Suite. A *NIX/*BSD system running Netatalk is capable of serving many Macintosh clients simultaneously as an AppleShare file server (AFP), AppleTalk router, *NIX/*BSD print server, and for accessing AppleTalk printers via Printer Access Protocol (PAP). Included are a number of minor printing and debugging utilities.

The suite contains:

• afpd - a file server that implements the Apple Filing Protocol, allowing clients running MacOS to access Unix file servers

• atalkd - an implementation of the AppleTalk protocol

• papd - a print server that enables Macintosh computers to access printers connected to Unix servers

• megatron - a tool to convert files in Macintosh specific formats like BinHex, AppleSingle, or MacBinary into files readable by Unix computers

• various supporting programs and utilities

Summary of hot stuff and enhancements

• AFP 3.3 support (necessary for TimeMachine and Lion)

• Robust network disconnect/reconnect, especially important for Time Machine

• Support for fast AFP searches (CNID backend "dbd" only)

• POSIX draft 1e ACL support

• Complete Netatalk volume compatible `ad` file utility suite

• Dynamic filesystem cache

• Builtin Zeroconf registration of the AFP server and TimeMachine volumes

• Support for ACLs without a common Directory Service between server and client

Important

The enhancements for fast AFP searches are only implemented for the CNID backend "dbd" and require changes to the underlying CNID database, ie an additional index. This breaks drop-in compatibility between the CNID backends "cdb" and "dbd". Once "dbd" has upgraded a CNID database of a volume, "cdb" will reject to open it.

• NEW: afpd: new option "-mimicmodel" for specifying Bonjour model registration

• UPD: Support for Berkeley DB 5.1

• UPD: case-conversion is based on Unicode 6.0.0

• UPD: cnid_metad: allow up to 4096 volumes

• UPD: afpd: only forward SIGTERM and SIGUSR1 from parent to childs

• UPD: afpd: use internal function instead of popening du -sh in order to calculate the used size of a volume for option "volsizelimit"

• UPD: afpd: Add negative UUID caching, enhance local UUID handling

• FIX: afpd: configuration reload with SIGHUP

• FIX: afpd: crashes in the dircache

• FIX: afpd: Correct afp logout vs dsi eof behaviour

• FIX: afpd: new catsearch was broken

• FIX: afpd: only use volume UUIDs in master afpd

• FIX: dbd: Multiple fixes, reliable locking

• FIX: ad file suite: fix an error that resulted in CNID database inconsistencies

Changes in 2.2-beta4

• NEW: afpd: new afpd.conf options "tcprcvbuf" and "tcpsndbuf" to customize the corresponding TCP socket options.

• NEW: afpd: new afpd.conf option "nozeroconf" which disabled automatic Zeroconf service registration.

• FIX: afpd: generate mersenne primes for DHX2 UAM once at startup, not for every login

• FIX: afpd: DSI streaming deadlock

• FIX: afpd: extended sleep

• FIX: afpd: directory cache

• FIX: Support for platforms that do not have the *at functions

• UPD: afpd: put POSIX write lock on volume files while reading them

Changes in 2.2-beta3

• FIX: afpd: fix option volsizelimit to return a usefull value for the volume free space using `du -sh` with popen

• FIX: afpd: fix idle connection disconnects

• FIX: afpd: don't disconnect sessions for clients if boottimes don't match

• FIX: afpd: better handling of very long filenames that contain many multibyte UTF-8 glyphs

Changes in 2.2-beta2

• NEW: afpd: AFP 3.3

• UPD: afpd: AFP 3.x can't be disabled

Changes in 2.2-beta1

• FIX: composition of Surrogate Pair

• UPD: gentoo: rc-update install don't hook in the Makefile

Changes in 2.2alpha5

• UPD: afpd: new option "searchdb" which enables fast catalog searches using the CNID db.

• UPD: Case-insensitive fast search with the CNID db

• UPD: cnid_dbd: afpd now passes the volume path, not the db path when connecting for a volume. cnid_dbd will read the ".AppleDesktop/.volinfo" file of the volume in order to figure out the CNID db path and the volume charset encoding.

Changes in 2.2alpha4

• NEW: Enhanced CNID "dbd" database for fast name search support. Important: this makes cnidscheme "cdb" incompatible with "dbd".

• NEW: afpd: support for fast catalog searches

• NEW: ad utility: ad find

• UPD: afpd: CNID database versioning check for "cdb" scheme

• UPD: cnid_dbd: CNID database versioning and upgrading. Additional CNID database index for fast name searches.

• NEW: afpd: automagic Zeroconf registration with avahi, registering both the service _afpovertcp._tcp and TimeMachine volumes with _adisk._tcp.

• UPD: afpd: ACLs usable (though not visible on the client side) without common directory service, by mapping ACLs to UARight

• UPD: afpd: performance improvements for ACL access calculations

• UPD: AppleTalk ist disabled by default at configuration time. If needed use configure switch --enable-ddp.

• FIX: afpd: Solaris 10 compatibilty fix: don't use SO_SNDTIMEO/SO_RCVTIMEO, use non-blocking IO and select instead.

• FIX: cnid_dbd: Solaris 10 compatibilty fix: don't use SO_SNDTIMEO/SO_RCVTIMEO, use non-blocking IO and select instead.

• REM: afile/achfile/apple_cm/apple_mv/apple_rm: use ad

Supported Platforms

As of Netatalk 2.2 the following operating systems are supported:

• FreeBSD

• Linux
