Although the helper software is not -+required, mount.cifs is recommended. Eventually the Samba 3.0 utility program -+"net" may also be helpful since it may someday provide easier mount syntax for -+users who are used to Windows e.g. net use <mount point> <UNC name or cifs URL> -+Note that running the Winbind pam/nss module (logon service) on all of your -+Linux clients is useful in mapping Uids and Gids consistently across the -+domain to the proper network user. The mount.cifs mount helper can be -+trivially built from Samba 3.0 or later source e.g. by executing: -+ -+ gcc samba/source/client/mount.cifs.c -o mount.cifs -+ -+Note that when the mount.cifs utility is run suid (allowing user mounts), -+in order to reduce risks, the "nosuid" mount flag is passed in on mount to -+disallow execution of an suid program mounted on the remote target. -+When mount is executed as root, nosuid is not passed in by default, -+and execution of suid programs on the remote target would be enabled -+by default. This can be changed, as with nfs and other filesystems, -+by simply specifying "nosuid" among the mount options. For user mounts -+though to be able to pass the suid flag to mount requires rebuilding -+mount.cifs with the following flag: -+ -+ gcc samba/source/client/mount.cifs.c -DCIFS_ALLOW_USR_SUID -o mount.cifs -+ -+There is a corresponding manual page for cifs mounting in the Samba 3.0 and -+later source tree in docs/manpages/mount.cifs.8 -+ -+Samba Considerations -+==================== -+To get the maximum benefit from the CIFS VFS, we recommend using a server that -+supports the SNIA CIFS Unix Extensions standard (e.g. Samba 2.2.5 or later or -+Samba 3.0) but the CIFS vfs works fine with a wide variety of CIFS servers. -+Note that uid, gid and file permissions will display default values if you do -+not have a server that supports the Unix extensions for CIFS (such as Samba -+2.2.5 or later). To enable the Unix CIFS Extensions in the Samba server, add -+the line: -+ -+ unix extensions = yes -+ -+to your smb.conf file on the server. Note that the following smb.conf settings -+are also useful (on the Samba server) when the majority of clients are Unix or -+Linux: -+ -+ case sensitive = yes -+ delete readonly = yes -+ ea support = yes -+ -+Note that ea support is required for supporting Linux xattrs. -+Some administrators also change the "map archive" and the "create mask" -+parameters from their default values. Creating special devices (mknod) -+remotely may require specifying a mkdev function to Samba if you are not using -+Samba 3.0.5 or later. For more information on these see the manual pages -+("man smb.conf") on the Samba server system. Note that the cifs vfs, -+unlike the smbfs vfs, does not read the smb.conf on the client system -+(the few optional settings are passed in on mount via -o parameters instead). -+Note that Samba 2.2.7 or later includes a fix that allows the CIFS VFS to delete -+open files (required for strict POSIX compliance). Windows Servers already -+supported this feature. Samba server does not allow symlinks that refer to files -+outside of the share, so in Samba versions prior to 3.0.5, most symlinks to -+files with absolute paths (ie beginning with slash) such as: -+ ln -s /mnt/foo bar -+would be forbidden. Samba 3.0.5 server or later includes the ability to create -+such symlinks safely by converting unsafe symlinks (ie symlinks to server -+files that are outside of the share) to a samba specific format on the server -+that is ignored by local server applications and non-cifs clients and that will -+not be traversed by the Samba server). This is opaque to the Linux client -+application using the cifs vfs. Absolute symlinks will work to Samba 3.0.5 or -+later, but only for remote clients using the CIFS Unix extensions, and will -+be invisbile to Windows clients and typically will not affect local -+applications running on the same server as Samba. -+ -+Use instructions: -+================ -+Once the CIFS VFS support is built into the kernel or installed as a module -+(cifs.o), you can use mount syntax like the following to access Samba or Windows -+servers: -+ -+ mount -t cifs //9.53.216.11/e$ /mnt -o user=myname,pass=mypassword -+ -+Before -o the option -v may be specified to make the mount.cifs -+mount helper display the mount steps more verbosely. -+After -o the following commonly used cifs vfs specific options -+are supported: -+ -+ user=<username> -+ pass=<password> -+ domain=<domain name> -+ -+Other cifs mount options are described below. Use of TCP names (in addition to -+ip addresses) is available if the mount helper (mount.cifs) is installed. If -+you do not trust the server to which are mounted, or if you do not have -+cifs signing enabled (and the physical network is insecure), consider use -+of the standard mount options "noexec" and "nosuid" to reduce the risk of -+running an altered binary on your local system (downloaded from a hostile server -+or altered by a hostile router). -+ -+When using the mount helper mount.cifs, passwords may be specified via alternate -+mechanisms, instead of specifying it after -o using the normal "pass=" syntax -+on the command line: -+1) By including it in a credential file. Specify credentials=filename as one -+of the mount options. Credential files contain two lines -+ username=someuser -+ password=your_password -+2) By specifying the password in the PASSWD environment variable (similarly -+the user name can be taken from the USER environment variable). -+3) By specifying the password in a file by name via PASSWD_FILE -+4) By specifying the password in a file by file descriptor via PASSWD_FD -+ -+If no password is provided, mount.cifs will prompt for password entry -+ -+Restrictions -+============ -+Servers must support the NTLM SMB dialect (which is the most recent, supported -+by Samba and Windows NT version 4, 2000 and XP and many other SMB/CIFS servers) -+Servers must support either "pure-TCP" (port 445 TCP/IP CIFS connections) or RFC -+1001/1002 support for "Netbios-Over-TCP/IP." Neither of these is likely to be a -+problem as most servers support this. IPv6 support is planned for the future. -+ -+CIFS VFS Mount Options -+====================== -+A partial list of the supported mount options follows: -+ user The user name to use when trying to establish -+ the CIFS session. -+ password The user password. If the mount helper is -+ installed, the user will be prompted for password -+ if it is not supplied. -+ ip The ip address of the target server -+ unc The target server Universal Network Name (export) to -+ mount. -+ domain Set the SMB/CIFS workgroup name prepended to the -+ username during CIFS session establishment -+ uid If CIFS Unix extensions are not supported by the server -+ this overrides the default uid for inodes. For mounts to -+ servers which do support the CIFS Unix extensions, such -+ as a properly configured Samba server, the server provides -+ the uid, gid and mode. For servers which do not support -+ the Unix extensions, the default uid (and gid) returned on -+ lookup of existing files is the uid (gid) of the person -+ who executed the mount (root, except when mount.cifs -+ is configured setuid for user mounts) unless the "uid=" -+ (gid) mount option is specified. For the uid (gid) of newly -+ created files and directories, ie files created since -+ the last mount of the server share, the expected uid -+ (gid) is cached as as long as the inode remains in -+ memory on the client. Also note that permission -+ checks (authorization checks) on accesses to a file occur -+ at the server, but there are cases in which an administrator -+ may want to restrict at the client as well. For those -+ servers which do not report a uid/gid owner -+ (such as Windows), permissions can also be checked at the -+ client, and a crude form of client side permission checking -+ can be enabled by specifying file_mode and dir_mode on -+ the client -+ gid If CIFS Unix extensions are not supported by the server -+ this overrides the default gid for inodes. -+ file_mode If CIFS Unix extensions are not supported by the server -+ this overrides the default mode for file inodes. -+ dir_mode If CIFS Unix extensions are not supported by the server -+ this overrides the default mode for directory inodes. -+ port attempt to contact the server on this tcp port, before -+ trying the usual ports (port 445, then 139). -+ iocharset Codepage used to convert local path names to and from -+ Unicode. Unicode is used by default for network path -+ names if the server supports it. If iocharset is -+ not specified then the nls_default specified -+ during the local client kernel build will be used. -+ If server does not support Unicode, this parameter is -+ unused. -+ rsize default read size -+ wsize default write size -+ rw mount the network share read-write (note that the -+ server may still consider the share read-only) -+ ro mount network share read-only -+ version used to distinguish different versions of the -+ mount helper utility (not typically needed) -+ sep if first mount option (after the -o), overrides -+ the comma as the separator between the mount -+ parms. e.g. -+ -o user=myname,password=mypassword,domain=mydom -+ could be passed instead with period as the separator by -+ -o sep=.user=myname.password=mypassword.domain=mydom -+ this might be useful when comma is contained within username -+ or password or domain. This option is less important -+ when the cifs mount helper cifs.mount (version 1.1 or later) -+ is used. -+ nosuid Do not allow remote executables with the suid bit -+ program to be executed. This is only meaningful for mounts -+ to servers such as Samba which support the CIFS Unix Extensions. -+ If you do not trust the servers in your network (your mount -+ targets) it is recommended that you specify this option for -+ greater security. -+ suid Allow remote files on this mountpoint with suid enabled to -+ be executed (default for mounts when executed as root, -+ nosuid is default for user mounts). -+ credentials Although ignored by the cifs kernel component, it is used by -+ the mount helper, mount.cifs. When mount.cifs is installed it -+ opens and reads the credential file specified in order -+ to obtain the userid and password arguments which are passed to -+ the cifs vfs. -+ guest Although ignored by the kernel component, the mount.cifs -+ mount helper will not prompt the user for a password -+ if guest is specified on the mount options. If no -+ password is specified a null password will be used. -+ -+The mount.cifs mount helper also accepts a few mount options before -o -+including: -+ -+ -S take password from stdin (equivalent to setting the environment -+ variable "PASSWD_FD=0" -+ -V print mount.cifs version -+ -? display simple usage information -+ -+With recent 2.6 kernel versions of modutils, the version of the cifs kernel -+module can be displayed via modinfo. -+ -+Misc /proc/fs/cifs Flags and Debug Info -+======================================= -+Informational pseudo-files: -+DebugData Displays information about active CIFS sessions -+ and shares. -+Stats Lists summary resource usage information as well as per -+ share statistics, if CONFIG_CIFS_STATS in enabled -+ in the kernel configuration. -+ -+Configuration pseudo-files: -+MultiuserMount If set to one, more than one CIFS session to -+ the same server ip address can be established -+ if more than one uid accesses the same mount -+ point and if the uids user/password mapping -+ information is available.

There are plenty of opportunities -+for visible, important contributions to this module. Here -+is a partial list of the known problems and missing features: -+ -+a) Support for SecurityDescriptors for chmod/chgrp/chown so -+these can be supported for Windows servers -+ -+b) Better pam/winbind integration -+ -+c) multi-user mounts - multiplexed sessionsetups over single vc -+(ie tcp session) - prettying up needed -+ -+d) Kerberos/SPNEGO session setup support - (started) -+ -+e) NTLMv2 authentication (mostly implemented) -+ -+f) MD5-HMAC signing SMB PDUs when SPNEGO style SessionSetup -+used (Kerberos or NTLMSSP). Signing alreadyimplemented for NTLM -+and raw NTLMSSP already. This is important when enabling -+extended security and mounting to Windows 2003 Servers -+ -+f) Directory entry caching relies on a 1 second timer, rather than -+using FindNotify or equivalent. - (started) -+ -+g) A few byte range testcases fail due to POSIX vs. Windows/CIFS -+style byte range lock differences -+ -+h) quota support -+ -+i) support for the Linux 2.5 kernel new feature get_xattr and set_xattr -+which will allow us to expose dos attributes as well as real -+ACLs. This support has been started in the current code, but is -+ifdeffed out. -+ -+k) finish writepages support (multi-page write behind for improved -+performance) and syncpage -+ -+l) hook lower into the sockets api (as NFS/SunRPC does) to avoid the -+extra copy in/out of the socket buffers in some cases. -+ -+m) finish support for IPv6. This is mostly complete but -+needs a simple inet_pton like function to convert ipv6 -+addresses in string representation. -+ -+o) Better optimize open (and pathbased setfilesize) to reduce the -+oplock breaks coming from windows srv. Piggyback identical file -+opens on top of each other by incrementing reference count rather -+than resending (helps reduce server resource utilization and avoid -+spurious oplock breaks). -+ -+p) Improve performance of readpages by sending more than one read -+at a time when 8 pages or more are requested. Evaluate whether -+reads larger than 16K would be helpful. -+ -+q) For support of Windows9x/98 we need to retry failed mounts -+to *SMBSERVER (default server name) with the uppercase hostname -+in the RFC1001 session_init request. -+ -+r) Add Extended Attributed support (for storing UID/GID info -+to Windows servers) -+ -+s) Finish fcntl D_NOTIFY support so kde and gnome file list windows -+will autorefresh -+ -+t) Add GUI tool to configure /proc/fs/cifs settings and for display of -+the CIFS statistics -+ -+KNOWN BUGS (updated May 27, 2004) -+==================================== -+1) existing symbolic links (Windows reparse points) are recognized but -+can not be created remotely. They are implemented for Samba and those that -+support the CIFS Unix extensions but Samba has a bug currently handling -+symlink text beginning with slash -+2) follow_link and readdir code does not follow dfs junctions -+but recognizes them -+3) create of new files to FAT partitions on Windows servers can -+succeed but still return access denied (appears to be Windows -+server not cifs client problem) and has not been reproduced recently. -+NTFS partitions do not have this problem. -+4) debug connectathon lock test case 10 which fails against -+Samba (may be unmappable due to POSIX to Windows lock model -+differences but worth investigating). Also debug Samba to -+see why lock test case 7 takes longer to complete to Samba -+than to Windows. -+ -+Misc testing to do -+================== -+1) check out max path names and max path name components against various server -+types. Try nested symlinks. Return max path name in stat -f information -+ -+2) Modify file portion of ltp so it can run against a mounted network -+share and run it against cifs vfs. -+ -+3) Additional performance testing and optimization using iozone and similar - -+there are some easy changes that can be done to parallelize sequential writes, -+and when signing is disabled to request larger read sizes (larger than -+negotiated size) and send larger write sizes to modern servers. -+ -+4) More exhaustively test the recently added NT4 support against various -+NT4 service pack levels. -+ ---- /dev/null -+++ b/fs/cifs/transport.c -@@ -0,0 +1,434 @@ -+/* -+ * fs/cifs/transport.c -+ * -+ * Copyright (C) International Business Machines Corp., 2002,2004 -+ * Author(s): Steve French (sfrench@us.ibm.com) -+ * -+ * This library is free software; you can redistribute it and/or modify -+ * it under the terms of the GNU Lesser General Public License as published -+ * by the Free Software Foundation; either version 2.1 of the License, or -+ * (at your option) any later version. -+ * -+ * This library is distributed in the hope that it will be useful, -+ * but WITHOUT ANY WARRANTY; without even the implied warranty of -+ * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The chip provides microphone and speaker interfaces -+ * which provide mono-channel audio at 8K samples per second via either -+ * 8-bit A-law or 8-bit mu-law encoding. Also, the chip features an -+ * ISDN BRI Line Interface Unit (LIU), I.430 S/T physical interface, -+ * which performs basic D channel LAPD processing and provides raw -+ * B channel data. The digital audio channel, the two ISDN B channels, -+ * and two 64 Kbps channels to the microprocessor are all interconnected -+ * via a multiplexer. -+ * -+ * This driver interfaces to the Linux HiSax ISDN driver, which performs -+ * all high-level Q.921 and Q.931 ISDN functions. The file is not -+ * itself a hardware driver; rather it uses functions exported by -+ * the AMD7930 driver in the sparcaudio subsystem (drivers/sbus/audio), -+ * allowing the chip to be simultaneously used for both audio and ISDN data. -+ * The hardware driver does _no_ buffering, but provides several callbacks -+ * which are called during interrupt service and should therefore run quickly. -+ * -+ * D channel transmission is performed by passing the hardware driver the -+ * address and size of an skb's data area, then waiting for a callback -+ * to signal successful transmission of the packet. A task is then -+ * queued to notify the HiSax driver that another packet may be transmitted. -+ * -+ * D channel reception is quite simple, mainly because of: -+ * 1) the slow speed of the D channel - 16 kbps, and -+ * 2) the presence of an 8- or 32-byte (depending on chip version) FIFO -+ * to buffer the D channel data on the chip -+ * Worst case scenario of back-to-back packets with the 8 byte buffer -+ * at 16 kbps yields an service time of 4 ms - long enough to preclude -+ * the need for fancy buffering. We queue a background task that copies -+ * data out of the receive buffer into an skb, and the hardware driver -+ * simply does nothing until we're done with the receive buffer and -+ * reset it for a new packet. -+ * -+ * B channel processing is more complex, because of: -+ * 1) the faster speed - 64 kbps, -+ * 2) the lack of any on-chip buffering (it interrupts for every byte), and -+ * 3) the lack of any chip support for HDLC encapsulation -+ * -+ * The HiSax driver can put each B channel into one of three modes - -+ * L1_MODE_NULL (channel disabled), L1_MODE_TRANS (transparent data relay), -+ * and L1_MODE_HDLC (HDLC encapsulation by low-level driver). -+ * L1_MODE_HDLC is the most common, used for almost all "pure" digital -+ * data sessions. L1_MODE_TRANS is used for ISDN audio. -+ * -+ * HDLC B channel transmission is performed via a large buffer into -+ * which the skb is copied while performing HDLC bit-stuffing. A CRC -+ * is computed and attached to the end of the buffer, which is then -+ * passed to the low-level routines for raw transmission. Once -+ * transmission is complete, the hardware driver is set to enter HDLC -+ * idle by successive transmission of mark (all 1) bytes, waiting for -+ * the ISDN driver to prepare another packet for transmission and -+ * deliver it. -+ * -+ * HDLC B channel reception is performed via an X-byte ring buffer -+ * divided into N sections of X/N bytes each. Defaults: X=256 bytes, N=4. -+ * As the hardware driver notifies us that each section is full, we -+ * hand it the next section and schedule a background task to peruse -+ * the received section, bit-by-bit, with an HDLC decoder. As -+ * packets are detected, they are copied into a large buffer while -+ * decoding HDLC bit-stuffing. The ending CRC is verified, and if -+ * it is correct, we alloc a new skb of the correct length (which we -+ * now know), copy the packet into it, and hand it to the upper layers. -+ * Optimization: for large packets, we hand the buffer (which also -+ * happens to be an skb) directly to the upper layer after an skb_trim, -+ * and alloc a new large buffer for future packets, thus avoiding a copy. -+ * Then we return to HDLC processing; state is saved between calls. -+ * -+ */ -+ -+#define __NO_VERSION__ -+#include "hisax.h" -+#include "../../sbus/audio/amd7930.h" -+#include "isac.h" -+#include "isdnl1.h" -+#include "rawhdlc.h" -+#include <linux/interrupt.h> -+ -+static const char *amd7930_revision = "$Revision: 1.8 $"; -+ -+#define RCV_BUFSIZE 1024 /* Size of raw receive buffer in bytes */ -+#define RCV_BUFBLKS 4 /* Number of blocks to divide buffer into -+ * (must divide RCV_BUFSIZE) */ -+ -+static void Bchan_fill_fifo(struct BCState *, struct sk_buff *); -+ -+static void -+Bchan_xmt_bh(struct BCState *bcs) -+{ -+ struct sk_buff *skb; -+ -+ if (bcs->hw.amd7930.tx_skb != NULL) { -+ dev_kfree_skb(bcs->hw.amd7930.tx_skb); -+ bcs->hw.amd7930.tx_skb = NULL; -+ } -+ -+ if ((skb = skb_dequeue(&bcs->squeue))) { -+ Bchan_fill_fifo(bcs, skb); -+ } else { -+ clear_bit(BC_FLG_BUSY, &bcs->Flag); -+ bcs->event |= 1 << B_XMTBUFREADY; -+ queue_task(&bcs->tqueue, &tq_immediate); -+ mark_bh(IMMEDIATE_BH); -+ } -+} -+ -+static void -+Bchan_xmit_callback(struct BCState *bcs) -+{ -+ queue_task(&bcs->hw.amd7930.tq_xmt, &tq_immediate); -+ mark_bh(IMMEDIATE_BH); -+} -+ -+/* B channel transmission: two modes (three, if you count L1_MODE_NULL) -+ * -+ * L1_MODE_HDLC - We need to do HDLC encapsulation before transmiting -+ * the packet (i.e. make_raw_hdlc_data).

[devel-0-0-13] -+ -+ * inode.c: implemented mini_fo_getattr, that was required for -+ 2.6 because inode_revalidate has been remove there, and the -+ old "du" bug returned. -+ -+ -+2005-04-20 <mk@mary> -+ -+ * aux.c: get_neg_sto_dentry(): allow to be called for dentries -+ in state UNMODIFIED, NON_EXISTANT _and_ DELETED. -+ -+2005-04-19 <mk@mary> -+ -+ * Fixed a bug under 2.6 that caused files deleted via mini_fo -+ not to be deleted properly and therefore the fs filled up -+ untill no memory was left. [devel-0-0-12] -+ -+ * Added basic hard link support. This means that creating -+ hardlinks will work, but existing ones will be treated as -+ individual files. [devel-0-0-11] -+ -+2005-04-17 <mk@mary> -+ -+ * Bugfixes -+ -+2005-04-13 root <mk@mary> -+ -+ * Added file state.c for the state transition -+ functions.

The problem was that -+ mini_fo_inode_revalidate didn't always copy the attributes -+ from the base inode properly. -+ -+2005-04-01 Markus Klotzbuecher <mk@chasey> -+ -+ * Merged devel branch back to main trunk and updated the -+ RELEASE notes. This will be 0-6-0-pre1. -+ -+2005-03-31 Markus Klotzbuecher <mk@chasey> -+ -+ * Fixed some bugs in rename_reg_file, that only showed up in -+ the kernel compile test. Kernel compiles cleanly ontop of -+ mini_fo, now also make mrproper etc. work. Seems pretty stable. -+ -+2005-03-28 Markus Klotzbuecher <mk@chasey> -+ -+ * Many, many directory renaming bugfixes and a lot of other -+ cleanup. Dir renaming seems to work relatively stable. -+ -+2005-03-22 Markus Klotzbuecher <mk@chasey> -+ -+ * Finished implementing lightweight directory renaming. Some -+ basic testing indicates it works fine. -+ Next is to implement testcases for the testsuite and confirm -+ everything is really working ok. -+ -+2005-03-18 Markus Klotzbuecher <mk@chasey> -+ -+ * Finished implementing meta.c stuff required for directory -+ renaming. -+ -+2005-03-17 Markus Klotzbuecher <mk@chasey> -+ -+ * Fixed all compile warnings + an extremly old bug that -+ somehow crept in while reworking the wol stuff to the META -+ system. Turning on -Werror again... :-) -+ -+ * Fixed some bugs in the new rename_reg_file function. -+ -+ * Rewrote mini_fo rename and split it into several -+ subfunctions, that handle the different types -+ seperately. Rewrote the regular file function aswell, as it -+ was implemented somewhat inefficient. -+ -+2005-03-16 Markus Klotzbuecher <mk@chasey> -+ -+ * Implemented new META subsystem, removed old WOL stuff in favor -+ if it. -+ -+ * After some basic testing everything seems ok... -+ -+2005-03-11 Markus Klotzbuecher <mk@chasey> -+ -+ * Renaming a non regular file caused trouble because I always -+ tried to copy the contents. Now I only do this for regular -+ files. mini_fo_rename still isn't implemented properly, renaming -+ of device files, symlinks etc. results in a empty regular file -+ instead of the proper type. -+ -+ * Directory renaming suddenly works! What a surprise! I guess -+ this is because renaming is implemented as making a copy and -+ removing the original. Still this might not work -+ everywhere... -+ -+2005-03-09 Markus Klotzbuecher <mk@chasey> -+ -+ * Bugfix, when a mini_fo directory that exists in storage -+ (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a -+ possibly existing WOL file contained in it needs to be -+ deleted too. -+ -+ * Starting cleanup: defined state names in order to get rid of -+ the state numbers. -+ -+2005-03-08 Markus Klotzbuecher <mk@chasey> -+ -+ * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um -+ -+ * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 = -+ DEL_REWRITTEN the hash was calculated from the base dentry, -+ which was wrong and and caused assertions in -+ __mini_fo_hidden_dentry to fail. -+ -+2005-02-21 <mk@mary> -+ -+ * Implemented directory deleting (inode.c) -+ -+ * main.c: made mini_fo_parse_options a little more robust. -+ -+2004-12-22 <mk@mary> -+ -+ * Makefile cleanup and uml stuff, removed unneccessary files -+ -+ * Created a new and hopefully more informative README -+ -+ * CHANGELOG: created a new CHANGELOG and added old entries reversely -+ -+ -+2004-10-24 Gleb Natapov <gleb@nbase.co.il> -+ -+ * Fix: owner and group where not correctly copied from base to -+ storage. -+ -+ -+2004-10-05 Gleb Natapov <gleb@nbase.co.il> -+ -+ * Implementation of fsync, fasync and lock mini_fo functions. -+ -+ -+2004-09-29 Bob Lee <bob@pantasys.com> -+ -+ * Fix of a serious pointer bug -+ -+ -+2004-09-28 Gleb Natapov <gleb@nbase.co.il> -+ -+ * Implementation of mini_fo_mknod and mini_fo_rename, support -+ for device files. -+ ---- /dev/null -+++ b/fs/mini_fo/dentry.c -@@ -0,0 +1,244 @@ -+/* -+ * Copyright (c) 1997-2003 Erez Zadok -+ * Copyright (c) 2001-2003 Stony Brook University -+ * -+ * For specific licensing information, see the COPYING file distributed with -+ * this package, or get one from ftp://ftp.filesystems.org/pub/fist/COPYING. -+ * -+ * This Copyright notice must be kept intact and distributed with all -+ * fistgen sources INCLUDING sources generated by fistgen. -+ */ -+/* -+ * Copyright (C) 2004, 2005 Markus Klotzbuecher <mk@creamnet.de> -+ * -+ * This program is free software;

This is done by redirecting modifying operations -+to a writeable location called "storage directory", and leaving the -+original data in the "base directory" untouched. When reading, the -+file system merges the modifed and original data so that only the -+newest versions will appear. This occurs transparently to the user, -+who can access the data like on any other read-write file system. -+ -+Base and storage directories may be located on the same or on -+different partitions and may be of different file system types. While -+the storage directory obviously needs to be writable, the base may or -+may not be writable, what doesn't matter as it will no be modified -+anyway. -+ -+ -+WHAT IS GOOD FOR? -+----------------- -+ -+The primary purpose of the mini_fo file system is to allow easy -+software updates to embedded systems, that often store their root -+file system in a read-only flash file system, but there are many -+more as for example sandboxing, or for allowing live-cds to -+permanently store information. -+ -+ -+BUILDING -+-------- -+This should be simple. Adjust the Makefile to point to the correct -+kernel headers you want to build the module for. Then: -+ -+ # make -+ -+should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6 -+kernel. -+ -+If you are building the module for you current kernel, you can install -+the module (as root): -+ -+ # make install -+ -+or uninstall with -+ -+ # make uninstall -+ -+ -+USING THE FILE SYSTEM -+-------------------- -+ -+the general mount syntax is: -+ -+ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\ -+ <base directory> <mount point> -+ -+Example: -+ -+You have mounted a cdrom to /mnt/cdrom and want to modifiy some files -+on it: -+ -+load the module (as root) -+ -+ # insmod mini_fo.o for a 2.4 kernel or -+ -+ # insmod mini_fo.ko for a 2.6 kernel -+ -+ -+create a storage dir in tmp and a mountpoint for mini_fo: -+ -+ # mkdir /tmp/sto -+ # mkdir /mnt/mini_fo -+ -+and mount the mini_fo file system: -+ -+ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo -+ -+ -+Now the data stored on the cd can be accessed via the mini_fo -+mountpoint just like any read-write file system, files can be modified -+and deleted, new ones can be created and so on. When done unmount the -+file system: -+ -+ # unmount /mnt/mini_fo -+ -+Note that if the file system is mounted again using the same storage -+file system, of course it will appear in the modified state again. If -+you remount it using an new empty storage directory, it will be -+unmodified. Therefore by executing: -+ -+ # cd /tmp/sto -+ # rm -rf * -+ -+you can nuke all the changes you made to the original file system. But -+ remember NEVER do this while the mini_fo file system is mounted! -+ -+ -+Alternatively you can use the mini_fo-overlay bash script, that -+simplifies managing mini_fo mounts. See TOOLS Section. -+ -+ -+TOOLS -+----- -+ -+mini_fo-merge (experimental): -+ -+This is a bash script that will merge changes contained in the storage -+directory back to the base directory. This allows mini_fo to function -+as a cache file system by overlaying a slow (network, ...) file system -+and using a fast (ramdisk, ...) as storage. When done, changes can be -+merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge -+-h" for details. -+ -+It can be usefull for merging changes back after a successfull test -+(patches, software updates...) -+ -+ -+mini_fo-overlay: -+ -+This bash script simplifies managing one or more mini_fo mounts. For -+overlaying a directory called "basedir1", you can just call: -+ -+ # mini_fo-overlay basedir1 -+ -+This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/" -+as storage to "/mnt/mini_fo-basedir1/". It has more options though, -+type "mini_fo-overlay -h" for details. -+ -+ -+DOCUMENTATION, REPORTING BUGS, GETTING HELP -+------------------------------------------- -+ -+Please visit the mini_fo project page at: -+ -+http://www.denx.de/twiki/bin/view/Know/MiniFOHome -+ -+ -+WARNINGS -+-------- -+ -+Never modify the base or the storage directorys while the mini_fo -+file system is mounted, or you might crash you system. Simply accessing -+and reading should not cause any trouble. -+ -+Exporting a mini_fo mount point via NFS has not been tested, and may -+or may not work. -+ -+Check the RELEASE_NOTES for details on bugs and features. -+ -+ -+ -+Copyright (C) 2004, 2005 Markus Klotzbuecher <mk@creamnet.de> -+ -+This program is free software; you can redistribute it and/or -+modify it under the terms of the GNU General Public License -+as published by the Free Software Foundation; either version -+2 of the License, or (at your option) any later version. -+ -+ ---- /dev/null -+++ b/fs/mini_fo/RELEASE_NOTES -@@ -0,0 +1,111 @@ -+Release: mini_fo-0.6.1 (v0-6-1) -+Date: 21.09.2005 -+ -+ -+Changes: -+-------- -+v0-6-1: -+ -+- bugfixes (see ChangeLog) -+ -+- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see -+ README for details). -+ -+v0-6-0: -+ -+- Support for 2.4 and 2.6 (see Makefile) -+ -+- Partial hard link support (creating works as expected, but already -+ existing links in the base file system will be treated as if they -+ were individual files). -+ -+- Various bugfixes and cleanups. -+ -+ -+v0-6-0-pre1: -+ -+- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of -+ many vital mini_fo parts such as the old whiteout list code which -+ has been replaced by the new META subsystem. -+ -+- Light weight directory renaming implemented. This means if a -+ directory is renamed via the mini_fo filesystem this will no longer -+ result in a complete copy in storage, instead only one empty -+ directory will be created. All base filed contained in the original -+ directory stay there until modified. -+ -+- Special files (creating, renaming, deleting etc.) now working. -+ -+- Many bugfixes and cleanup, mini_fo is now a lot more stable. -+ -+ -+v0-5-10: -+ -+- Final release of the 0-5-* versions. Next will be a complete rewrite -+ of many features. This release contains several bugfixes related to -+ directory renaming. -+ -+ -+v0-5-10-pre6: -+ -+- Lots of cleanup and several bugfixes related to directory deleting -+ -+- Directory renaming suddenly works, what is most likely due to the -+ fact tha that "mv" is smart: if the classic rename doesn't work it -+ will assume that source and target file are on different fs and will -+ copy the directory and try to remove the source directory. Until -+ directory removing wasn't implemented, it would fail to do this and -+ rollback. -+ So, directory renaming works for now, but it doesn't yet do what you -+ would expect from a overlay fs, so use with care. -+ -+ -+v0-5-10-pre5: -+ -+- implemented directory deleting -+- made parsing of mount options more stable -+- New format of mount options! (See README) -+- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll -+ happily assume it never existed! -+ -+ -+Implemented features: -+--------------------- -+ -+- creating hard links (see BUGS on already existing hard links) -+- lightweight directory renaming -+- renaming device files, pipes, sockets, etc. -+- creating, renaming, deleting of special files -+- deleting directorys -+- general directory reading (simple "ls" ) -+- creating files in existing directorys -+- creating directorys -+- renaming files. -+- reading and writing files (involves opening) -+- appending to files (creates copy in storage) -+- deleting files -+- llseek works too, what allows editors to work -+- persistency (a deleted file stay deleted over remounts) -+- use of symbolic links -+- creating of device files -+ -+ -+Not (yet) implemented features: -+------------------------------- -+ -+- full hard link support. -+ -+ -+ -+BUGS: -+----- -+ -+Hard links in the base file system will be treated as individual -+files, not as links to one inode. -+ -+The main problem with hard links isn't allowing to create them, but -+their pure existence. If you modify a base hard link, the changes made -+will only show up on this link, the other link will remain in the -+original state. I hope to fix this someday. Please note that this does -+not effect the special hard links '.' and '..', that are handled -+seperately by the lower fs. ---- /dev/null -+++ b/fs/mini_fo/state.c -@@ -0,0 +1,620 @@ -+/* -+ * Copyright (C) 2005 Markus Klotzbuecher <mk@creamnet.de> -+ * -+ * This program is free software;

A state variable is provided -+ * to the algorihtm to store persistant variables. -+ * (4) Core eventually resets the search offset and forwards the find() -+ * request to the algorithm. -+ * (5) Algorithm calls get_next_block() provided by the user continously -+ * to fetch the data to be searched in block by block. -+ * (6) Algorithm invokes finish() after the last call to get_next_block -+ * to clean up any leftovers from get_next_block. (Optional) -+ * (7) User destroys the configuration by calling _destroy(). -+ * (8) Core notifies the algorithm to destroy algorithm specific -+ * allocations. (Optional) -+ * -+ * USAGE -+ * -+ * Before a search can be performed, a configuration must be created -+ * by calling textsearch_prepare() specyfing the searching algorithm and -+ * the pattern to look for. The returned configuration may then be used -+ * for an arbitary amount of times and even in parallel as long as a -+ * separate struct ts_state variable is provided to every instance. -+ * -+ * The actual search is performed by either calling textsearch_find_- -+ * continuous() for linear data or by providing an own get_next_block() -+ * implementation and calling textsearch_find(). Both functions return -+ * the position of the first occurrence of the patern or UINT_MAX if -+ * no match was found. Subsequent occurences can be found by calling -+ * textsearch_next() regardless of the linearity of the data. -+ * -+ * Once you're done using a configuration it must be given back via -+ * textsearch_destroy. -+ * -+ * EXAMPLE -+ * -+ * int pos; -+ * struct ts_config *conf; -+ * struct ts_state state; -+ * const char *pattern = "chicken"; -+ * const char *example = "We dance the funky chicken"; -+ * -+ * conf = textsearch_prepare("kmp", pattern, strlen(pattern), -+ * GFP_KERNEL, TS_AUTOLOAD); -+ * if (IS_ERR(conf)) { -+ * err = PTR_ERR(conf); -+ * goto errout; -+ * } -+ * -+ * pos = textsearch_find_continuous(conf, &state, example, strlen(example)); -+ * if (pos != UINT_MAX) -+ * panic("Oh my god, dancing chickens at %d\n", pos); -+ * -+ * textsearch_destroy(conf); -+ * -+ * ========================================================================== -+ */ -+ -+#include <linux/config.h> -+#include <linux/module.h> -+#include <linux/types.h> -+#include <linux/string.h> -+#include <linux/init.h> -+#include <linux/netfilter_ipv4/lockhelp.h> -+#include "textsearch.h" -+ -+static LIST_HEAD(ts_ops); -+static spinlock_t ts_mod_lock = SPIN_LOCK_UNLOCKED; -+static DECLARE_RWLOCK(ts_ops_lock); -+ -+static inline struct ts_ops *lookup_ts_algo(const char *name) -+{ -+ struct ts_ops *o; -+ -+ read_lock(&ts_ops_lock); -+ list_for_each_entry(o, &ts_ops, list) { -+ if (!strcmp(name, o->name)) { -+ MOD_INC_USE_COUNT; -+ read_unlock(&ts_ops_lock); -+ return o; -+ } -+ } -+ read_unlock(&ts_ops_lock); -+ -+ return NULL; -+} -+ -+/** -+ * textsearch_register - register a textsearch module -+ * @ops: operations lookup table -+ * -+ * This function must be called by textsearch modules to announce -+ * their presence.
