1 OpenAFS News -- history of user-visible changes. October 19, 2001
3 * Changes incorporated in OpenAFS 1.3
5 ** Mountpoint directory information can be faked by the cache manager,
6 making operations such as stat'ing all cells under /afs much faster.
7 This is enabled by passing -fakestat to afsd, but might not be stable
10 * Changes incorporated in OpenAFS 1.2.3
12 ** Cell aliases for dynroot can be specified in the CellAlias file in
13 /usr/vice/etc or /usr/local/etc/openafs, in format "realname alias",
14 one per line. They can also be managed at runtime with "fs newalias"
17 * Changes incorporated in OpenAFS 1.2.2
19 ** Solaris 9 and Linux PA-RISC are now supported
21 ** fileserver will not erroneously delay legitimate errors for 3 seconds
22 after 10 errors are returned (e.g. stat() on a directory you can't read)
24 ** Rx MTU calculation now works for Irix, Solaris and Linux
26 ** If afsd is started with the -dynroot flag, /afs will be locally
27 generated from the CellServDB. AFSDB cells will be mounted
28 automatically upon access.
30 ** The namei fileserver allows vice "partitions" to be directories instead
31 of partitions and will attach and display accordingly. Creating the file
32 "AlwaysAttach" in the /vicepX directory is used as the trigger to attach it.
34 ** TSM support for butc no longer requires editing a Makefile, simply
35 specify the --enable-tivoli-tsm configure option.
37 ** Linux builds no longer require source changes every time the kernel
38 inode structure changes; the OpenAFS sources will now configure
39 itself to the actual inode structure as defined in the kernel
42 * Changes incorporated in OpenAFS 1.2.1
44 ** vfsck on Digital UNIX and Solaris will now refuse to fsck mounted
47 * Changes incorporated in OpenAFS 1.2.0
49 ** AFS now supports --prefix and the other directory options of
50 configure. By default AFS builds assuming it will be installed in
51 /usr/local. In order to get traditional AFS directory paths (/usr/afs
52 and /usr/vice/etc) use the --enable-transarc-paths option to
53 configure. More details on the new directory layout are found in README.
55 * Changes incorporated in OpenAFS 1.1.1a
57 ** Windows 95/98/ME/NT/2000 - Consistent versioning
58 Installation, AFS Control Center, Client dialog boxes and properties
59 pages for executables display a consistent OpenAFS version number.
60 Installation detects previous installation and prompts the user for upgrade
63 ** Windows 95/98/ME/NT/2000 - Installation features
64 During installation the user can select the source of the CellservDB file,
65 AFS home cell, and drive mappings. During installation a drive path
66 mapping can include a variable that will be substituted with the current
67 UserName that is logged in.
69 ** Windows 2000/NT - Integrated logon
70 The Integrated Logon feature works now.
72 ** Windows 95/98/ME - Logon script features
73 The Windows 95/98/ME client now offers a command-line option for starting up
74 the AFS client without authenication. It is now possilbe to start the AFS
75 client first and obtain tokens, and map drives all through Windows scripts.
76 This helps using Windows 95/98/ME client in Kerberos 5 environment.
78 ** Windows 2000/NT - LANA numbers
79 AFS client now scans the LANA numbers to establish the correct NETBIOS
80 connection. NetBEUI is no longer needed. The user no longer needs to find
81 the correct LANA number.
83 ** Windows 2000/NT - OpenAFS naming consistancy
84 Further progress has been made to remove references to "Transarc AFS"
85 and replace with "OpenAFS".
89 * Changes since OpenAFS 1.0
91 ** AFS now builds with configure. The README for building has been
92 updated and includes full details.
94 ** A client system can now have multiple sysname values for @sys.
95 They will be searched in order when looking up files in AFS. The
96 -newsysname argument to fs sysname can be repeated to set multiple
99 ** A new system group is created for new cells (system:ptsviewers
100 with id -203). If this group exists, members of this group can
101 examine and read the entire protection database. They can examine
102 all users and groups and can get the membership of any group.
104 ** A new program, pt_util has been added to the distribution. This
105 program allows users to print the contents of the protection
106 database or to edit the protection database without running a
107 ptserver. It can be used to set up a new cell without ever running
108 in noauth mode. Run pt_util -h for help.
110 ** The fs setcrypt and fs getcrypt commands have been added. These
111 commands allow the system administrator to require that the client
112 encrypt all authenticated traffic between the client workstation
113 and AFS. The encryption used is weak, but is likely better than
114 sending unencrypted traffic in most environments. Some functions,
115 such as looking for a volume may not be encrypted, but data
116 transfer certainly is. By default data is not encrypted. At this
117 time no significant experimentation with server performance has
120 ** By default AFS is compiled with AFS_AFSDB_ENV, enabling the -afsdb
121 option to be given to afsd on startup. If this option is used, then new
122 cells will be looked up using AFSDB records stored in DNS if they
123 are not found in CellServDB. This means that users can create
124 cross-cell mountpoints in directories they control to access cells
125 not in root.afs, and that cells in root.afs need not be in the
128 ** AFS database servers can be marked as read-only clones. Surround
129 the hostname in square brackets on the bos addhost command and the
130 database server will never be elected sync site. This is useful
131 for cells distributed over a wide region.
133 ** The AFS servers now support the -syslog flag. This flag causes
134 them to log to syslog rather than to files. This flag is not
135 supported on NT. For all servers besides the salvager, the flag can
136 also be specified as -syslog=facility, where facility is an integer
137 facility code from syslog.h. A -syslogfacility option is provided for
138 the salvager to accomplish the same goal.
140 ** If the --enable-fast-restart flag is given when configuring AFS,
141 then the salvager supports the -dontsalvage flag which causes it to
142 exit without salvaging any volumes. If this is configured into the
143 third command of a fs process, then the fileserver will start without
144 salvaging. It will fail to attach volumes that need salvaging and they
145 can be salvaged manually. This provides significantly better server
146 startup performance at the cost of administrative complexity.
148 ** If the --enable-bitmap-later flag is given when configuring AFS,
149 then the fileserver creates bitmaps for free vnodes on demand, allowing
152 ** If bosserver finds a BosConfig.new file at startup, it reads this
153 file and renames it to BosConfig. This allows bosserver to be
154 reconfigured at next restart.
156 ** The bosserver can be placed in a restricted mode in
157 which AFS superusers are only granted limited access to the server
158 host. The following functionality is disabled when restricted mode is in
162 bos getlog (except for files with no '/'s in their name)*
168 specific exceptions are made for functionality that "bos salvage"
171 a cron bnode who's name is "salvage-tmp", time is now, and command
172 begins with "/usr/afs/bin/salvager" may be created. This bnode
173 deletes itself when complete, so no special "delete" support is needed.
174 This functionality may be removed in the future if a "Salvage" RPC is
177 The file with the exact path /usr/afs/logs/SalvageLog may be fetched,
178 since that is how bos salvage [...] -showlog is implimented.
180 Restricted mode is enabled using a new bos command (bos setrestricted)
181 or bossever command line switch (bosserver -restricted). Restricted
182 mode can be disabled by a) sending the bosserver process a SIGFPE (which
183 will then allow restricted operations until the next restart or
184 setrestricted command) or b) editing /usr/afs/local/BosConfig
185 (or BosConfig.new), and restarting the bosserver.
187 ** The bos UserList of trusted administrators can now contain
188 cross-realm Kerberos principals.
190 ** udebug now takes --server not --servers.
192 ** Several error messages have been improved to include volume
195 ** Several new ports have been included for UNIX platforms: Darwin
196 (ppc_darwin_12 and ppc_darwin_13), Linux 2.4 (i386_linux24), Linux on
197 the Powerpc (ppc_linux22 and ppc_linux24), Linux on the Sparc
198 (sparc_linux22, sparc64_linux22 and sparc64_linux24) .
200 ** Incomplete FreeBSD and Alpha Linux ports are included. The
201 FreeBSD port has a working server and the Alpha Linux port has a
202 partially working client.
204 ** A native client for Windows 95/98/ME has been added to the distribution.
205 With this program, a gateway machine is no longer required for Windows 9x
206 to access AFS files. One drive letter will be created on your machine by
207 default - Z:. The Z: drive will be the root of the AFS tree, allowing you
208 to browse all sites that have AFS servers available. Additional drive
209 letters can be defined for other AFS directories. A Windows Explorer
210 shell extension is included that allows you to right click on items
211 within an AFS tree to bring up an "AFS" menu item and perform various
212 operations on a file or directory. The most useful item is "Access
213 Control Lists", which allows you to view and edit the permissions of a
214 particular directory. Command line tools are also available in the
215 install directory. These commands include klog, unlog, tokens, kpasswd,
216 symlink, fs and pts. The installable includes a readme file that contains
217 more information on how to use the client program and known issues.
219 ** support for large caches in afsd. Cachefiles are stored in
220 subdirectories. The default is 2048 files per subdirectory, which
221 should work fine in most situations. You can use the new afsd
222 option -files_per_subdir to change this number. Note that the first
223 time you run afsd with this patch, your cachefiles will get moved
224 into subdirectories. If you subsequently run an older version of
225 afsd, you will lose all your cached files.
