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