1 OpenAFS News -- history of user-visible changes. July 22, 2002.
3 * Changes incorporated in OpenAFS 1.3
5 ** When fakestat is enabled on MacOSX, the Finder can be used to browse
6 a fully-populated /afs directory. However, this precludes reliable
7 use of entire volumes as MacOS bundles (i.e. containing a Contents
8 directory in the root of the volume).
10 ** Mountpoint directory information can be faked by the cache manager,
11 making operations such as stat'ing all cells under /afs much faster.
12 This is enabled by passing -fakestat to afsd, but might not be stable
15 * Changes incorporated in OpenAFS 1.2.6
17 ** Mountpoint directory information can be faked by the cache manager,
18 making operations such as stat'ing all cells under /afs much faster.
19 This is enabled by passing -fakestat to afsd.
21 ** Solaris 9 FCS and Solaris 7 and 8 x86 are now supported.
23 * Changes incorporated in OpenAFS 1.2.5
25 ** A remote denial of service attack in the AIX and IRIX clients has
26 been fixed. Users of those platforms are strongly encouraged to
29 ** Fixed race conditions in fileserver that could result in crash.
31 * Changes incorporated in OpenAFS 1.2.4
33 ** Server logfiles now more consistant about format in which hosts are
36 ** vfsck on Solaris will now allow force runs (using -y flag) even if old
39 * Changes incorporated in OpenAFS 1.2.3
41 ** Cell aliases for dynroot can be specified in the CellAlias file in
42 /usr/vice/etc or /usr/local/etc/openafs, in format "realname alias",
43 one per line. They can also be managed at runtime with "fs newalias"
46 * Changes incorporated in OpenAFS 1.2.2
48 ** Solaris 9 and Linux PA-RISC are now supported
50 ** fileserver will not erroneously delay legitimate errors for 3 seconds
51 after 10 errors are returned (e.g. stat() on a directory you can't read)
53 ** Rx MTU calculation now works for Irix, Solaris and Linux
55 ** If afsd is started with the -dynroot flag, /afs will be locally
56 generated from the CellServDB. AFSDB cells will be mounted
57 automatically upon access.
59 ** The namei fileserver allows vice "partitions" to be directories instead
60 of partitions and will attach and display accordingly. Creating the file
61 "AlwaysAttach" in the /vicepX directory is used as the trigger to attach it.
63 ** TSM support for butc no longer requires editing a Makefile, simply
64 specify the --enable-tivoli-tsm configure option.
66 ** Linux builds no longer require source changes every time the kernel
67 inode structure changes; the OpenAFS sources will now configure
68 itself to the actual inode structure as defined in the kernel
71 * Changes incorporated in OpenAFS 1.2.1
73 ** vfsck on Digital UNIX and Solaris will now refuse to fsck mounted
76 * Changes incorporated in OpenAFS 1.2.0
78 ** AFS now supports --prefix and the other directory options of
79 configure. By default AFS builds assuming it will be installed in
80 /usr/local. In order to get traditional AFS directory paths (/usr/afs
81 and /usr/vice/etc) use the --enable-transarc-paths option to
82 configure. More details on the new directory layout are found in README.
84 * Changes incorporated in OpenAFS 1.1.1a
86 ** Windows 95/98/ME/NT/2000 - Consistent versioning
87 Installation, AFS Control Center, Client dialog boxes and properties
88 pages for executables display a consistent OpenAFS version number.
89 Installation detects previous installation and prompts the user for upgrade
92 ** Windows 95/98/ME/NT/2000 - Installation features
93 During installation the user can select the source of the CellservDB file,
94 AFS home cell, and drive mappings. During installation a drive path
95 mapping can include a variable that will be substituted with the current
96 UserName that is logged in.
98 ** Windows 2000/NT - Integrated logon
99 The Integrated Logon feature works now.
101 ** Windows 95/98/ME - Logon script features
102 The Windows 95/98/ME client now offers a command-line option for starting up
103 the AFS client without authenication. It is now possilbe to start the AFS
104 client first and obtain tokens, and map drives all through Windows scripts.
105 This helps using Windows 95/98/ME client in Kerberos 5 environment.
107 ** Windows 2000/NT - LANA numbers
108 AFS client now scans the LANA numbers to establish the correct NETBIOS
109 connection. NetBEUI is no longer needed. The user no longer needs to find
110 the correct LANA number.
112 ** Windows 2000/NT - OpenAFS naming consistancy
113 Further progress has been made to remove references to "Transarc AFS"
114 and replace with "OpenAFS".
118 * Changes since OpenAFS 1.0
120 ** AFS now builds with configure. The README for building has been
121 updated and includes full details.
123 ** A client system can now have multiple sysname values for @sys.
124 They will be searched in order when looking up files in AFS. The
125 -newsysname argument to fs sysname can be repeated to set multiple
128 ** A new system group is created for new cells (system:ptsviewers
129 with id -203). If this group exists, members of this group can
130 examine and read the entire protection database. They can examine
131 all users and groups and can get the membership of any group.
133 ** A new program, pt_util has been added to the distribution. This
134 program allows users to print the contents of the protection
135 database or to edit the protection database without running a
136 ptserver. It can be used to set up a new cell without ever running
137 in noauth mode. Run pt_util -h for help.
139 ** The fs setcrypt and fs getcrypt commands have been added. These
140 commands allow the system administrator to require that the client
141 encrypt all authenticated traffic between the client workstation
142 and AFS. The encryption used is weak, but is likely better than
143 sending unencrypted traffic in most environments. Some functions,
144 such as looking for a volume may not be encrypted, but data
145 transfer certainly is. By default data is not encrypted. At this
146 time no significant experimentation with server performance has
149 ** By default AFS is compiled with AFS_AFSDB_ENV, enabling the -afsdb
150 option to be given to afsd on startup. If this option is used, then new
151 cells will be looked up using AFSDB records stored in DNS if they
152 are not found in CellServDB. This means that users can create
153 cross-cell mountpoints in directories they control to access cells
154 not in root.afs, and that cells in root.afs need not be in the
157 ** AFS database servers can be marked as read-only clones. Surround
158 the hostname in square brackets on the bos addhost command and the
159 database server will never be elected sync site. This is useful
160 for cells distributed over a wide region.
162 ** The AFS servers now support the -syslog flag. This flag causes
163 them to log to syslog rather than to files. This flag is not
164 supported on NT. For all servers besides the salvager, the flag can
165 also be specified as -syslog=facility, where facility is an integer
166 facility code from syslog.h. A -syslogfacility option is provided for
167 the salvager to accomplish the same goal.
169 ** If the --enable-fast-restart flag is given when configuring AFS,
170 then the salvager supports the -dontsalvage flag which causes it to
171 exit without salvaging any volumes. If this is configured into the
172 third command of a fs process, then the fileserver will start without
173 salvaging. It will fail to attach volumes that need salvaging and they
174 can be salvaged manually. This provides significantly better server
175 startup performance at the cost of administrative complexity.
177 ** If the --enable-bitmap-later flag is given when configuring AFS,
178 then the fileserver creates bitmaps for free vnodes on demand, allowing
181 ** If bosserver finds a BosConfig.new file at startup, it reads this
182 file and renames it to BosConfig. This allows bosserver to be
183 reconfigured at next restart.
185 ** The bosserver can be placed in a restricted mode in
186 which AFS superusers are only granted limited access to the server
187 host. The following functionality is disabled when restricted mode is in
191 bos getlog (except for files with no '/'s in their name)*
197 specific exceptions are made for functionality that "bos salvage"
200 a cron bnode who's name is "salvage-tmp", time is now, and command
201 begins with "/usr/afs/bin/salvager" may be created. This bnode
202 deletes itself when complete, so no special "delete" support is needed.
203 This functionality may be removed in the future if a "Salvage" RPC is
206 The file with the exact path /usr/afs/logs/SalvageLog may be fetched,
207 since that is how bos salvage [...] -showlog is implimented.
209 Restricted mode is enabled using a new bos command (bos setrestricted)
210 or bossever command line switch (bosserver -restricted). Restricted
211 mode can be disabled by a) sending the bosserver process a SIGFPE (which
212 will then allow restricted operations until the next restart or
213 setrestricted command) or b) editing /usr/afs/local/BosConfig
214 (or BosConfig.new), and restarting the bosserver.
216 ** The bos UserList of trusted administrators can now contain
217 cross-realm Kerberos principals.
219 ** udebug now takes --server not --servers.
221 ** Several error messages have been improved to include volume
224 ** Several new ports have been included for UNIX platforms: Darwin
225 (ppc_darwin_12 and ppc_darwin_13), Linux 2.4 (i386_linux24), Linux on
226 the Powerpc (ppc_linux22 and ppc_linux24), Linux on the Sparc
227 (sparc_linux22, sparc64_linux22 and sparc64_linux24) .
229 ** Incomplete FreeBSD and Alpha Linux ports are included. The
230 FreeBSD port has a working server and the Alpha Linux port has a
231 partially working client.
233 ** A native client for Windows 95/98/ME has been added to the distribution.
234 With this program, a gateway machine is no longer required for Windows 9x
235 to access AFS files. One drive letter will be created on your machine by
236 default - Z:. The Z: drive will be the root of the AFS tree, allowing you
237 to browse all sites that have AFS servers available. Additional drive
238 letters can be defined for other AFS directories. A Windows Explorer
239 shell extension is included that allows you to right click on items
240 within an AFS tree to bring up an "AFS" menu item and perform various
241 operations on a file or directory. The most useful item is "Access
242 Control Lists", which allows you to view and edit the permissions of a
243 particular directory. Command line tools are also available in the
244 install directory. These commands include klog, unlog, tokens, kpasswd,
245 symlink, fs and pts. The installable includes a readme file that contains
246 more information on how to use the client program and known issues.
248 ** support for large caches in afsd. Cachefiles are stored in
249 subdirectories. The default is 2048 files per subdirectory, which
250 should work fine in most situations. You can use the new afsd
251 option -files_per_subdir to change this number. Note that the first
252 time you run afsd with this patch, your cachefiles will get moved
253 into subdirectories. If you subsequently run an older version of
254 afsd, you will lose all your cached files.
