[PATCH] BLOCK: Make it possible to disable the block layer [try #6] Make it possible to disable the block layer. Not all embedded devices require it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require the block layer to be present. This patch does the following: (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev support. (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls an item that uses the block layer. This includes: (*) Block I/O tracing. (*) Disk partition code. (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS. (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the block layer to do scheduling. Some drivers that use SCSI facilities - such as USB storage - end up disabled indirectly from this. (*) Various block-based device drivers, such as IDE and the old CDROM drivers. (*) MTD blockdev handling and FTL. (*) JFFS - which uses set_bdev_super(), something it could avoid doing by taking a leaf out of JFFS2's book. (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is, however, still used in places, and so is still available. (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and parts of linux/fs.h. (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK. (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK. (*) set_page_dirty() doesn't call __set_page_dirty_buffers() if CONFIG_BLOCK is not enabled. (*) fs/no-block.c is created to hold out-of-line stubs and things that are required when CONFIG_BLOCK is not set: (*) Default blockdev file operations (to give error ENODEV on opening). (*) Makes some /proc changes: (*) /proc/devices does not list any blockdevs. (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK. (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK. (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if given command other than Q_SYNC or if a special device is specified. (*) In init/do_mounts.c, no reference is made to the blockdev routines if CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2. (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return error ENOSYS by way of cond_syscall if so). (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if CONFIG_BLOCK is not set, since they can't then happen.

config ECRYPT_FS
tristate "eCrypt filesystem layer support (EXPERIMENTAL)"
[PATCH] eCryptfs: Public key transport mechanism This is the transport code for public key functionality in eCryptfs. It manages encryption/decryption request queues with a transport mechanism. Currently, netlink is the only implemented transport. Each inode has a unique File Encryption Key (FEK). Under passphrase, a File Encryption Key Encryption Key (FEKEK) is generated from a salt/passphrase combo on mount. This FEKEK encrypts each FEK and writes it into the header of each file using the packet format specified in RFC 2440. This is all symmetric key encryption, so it can all be done via the kernel crypto API. These new patches introduce public key encryption of the FEK. There is no asymmetric key encryption support in the kernel crypto API, so eCryptfs pushes the FEK encryption and decryption out to a userspace daemon. After considering our requirements and determining the complexity of using various transport mechanisms, we settled on netlink for this communication. eCryptfs stores authentication tokens into the kernel keyring. These tokens correlate with individual keys. For passphrase mode of operation, the authentication token contains the symmetric FEKEK. For public key, the authentication token contains a PKI type and an opaque data blob managed by individual PKI modules in userspace. Each user who opens a file under an eCryptfs partition mounted in public key mode must be running a daemon. That daemon has the user's credentials and has access to all of the keys to which the user should have access. The daemon, when started, initializes the pluggable PKI modules available on the system and registers itself with the eCryptfs kernel module. Userspace utilities register public key authentication tokens into the user session keyring. These authentication tokens correlate key signatures with PKI modules and PKI blobs. The PKI blobs contain PKI-specific information necessary for the PKI module to carry out asymmetric key encryption and decryption. When the eCryptfs module parses the header of an existing file and finds a Tag 1 (Public Key) packet (see RFC 2440), it reads in the public key identifier (signature). The asymmetrically encrypted FEK is in the Tag 1 packet; eCryptfs puts together a decrypt request packet containing the signature and the encrypted FEK, then it passes it to the daemon registered for the current->euid via a netlink unicast to the PID of the daemon, which was registered at the time the daemon was started by the user. The daemon actually just makes calls to libecryptfs, which implements request packet parsing and manages PKI modules. libecryptfs grabs the public key authentication token for the given signature from the user session keyring. This auth tok tells libecryptfs which PKI module should receive the request. libecryptfs then makes a decrypt() call to the PKI module, and it passes along the PKI block from the auth tok. The PKI uses the blob to figure out how it should decrypt the data passed to it; it performs the decryption and passes the decrypted data back to libecryptfs. libecryptfs then puts together a reply packet with the decrypted FEK and passes that back to the eCryptfs module. The eCryptfs module manages these request callouts to userspace code via message context structs. The module maintains an array of message context structs and places the elements of the array on two lists: a free and an allocated list. When eCryptfs wants to make a request, it moves a msg ctx from the free list to the allocated list, sets its state to pending, and fires off the message to the user's registered daemon. When eCryptfs receives a netlink message (via the callback), it correlates the msg ctx struct in the alloc list with the data in the message itself. The msg->index contains the offset of the array of msg ctx structs. It verifies that the registered daemon PID is the same as the PID of the process that sent the message. It also validates a sequence number between the received packet and the msg ctx. Then, it copies the contents of the message (the reply packet) into the msg ctx struct, sets the state in the msg ctx to done, and wakes up the process that was sleeping while waiting for the reply. The sleeping process was whatever was performing the sys_open(). This process originally called ecryptfs_send_message(); it is now in ecryptfs_wait_for_response(). When it wakes up and sees that the msg ctx state was set to done, it returns a pointer to the message contents (the reply packet) and returns. If all went well, this packet contains the decrypted FEK, which is then copied into the crypt_stat struct, and life continues as normal. The case for creation of a new file is very similar, only instead of a decrypt request, eCryptfs sends out an encrypt request. > - We have a great clod of key mangement code in-kernel. Why is that > not suitable (or growable) for public key management? eCryptfs uses Howells' keyring to store persistent key data and PKI state information. It defers public key cryptographic transformations to userspace code. The userspace data manipulation request really is orthogonal to key management in and of itself. What eCryptfs basically needs is a secure way to communicate with a particular daemon for a particular task doing a syscall, based on the UID. Nothing running under another UID should be able to access that channel of communication. > - Is it appropriate that new infrastructure for public key > management be private to a particular fs? The messaging.c file contains a lot of code that, perhaps, could be extracted into a separate kernel service. In essence, this would be a sort of request/reply mechanism that would involve a userspace daemon. I am not aware of anything that does quite what eCryptfs does, so I was not aware of any existing tools to do just what we wanted. > What happens if one of these daemons exits without sending a quit > message? There is a stale uid<->pid association in the hash table for that user. When the user registers a new daemon, eCryptfs cleans up the old association and generates a new one. See ecryptfs_process_helo(). > - _why_ does it use netlink? Netlink provides the transport mechanism that would minimize the complexity of the implementation, given that we can have multiple daemons (one per user).

Saying Y here includes support for SquashFS 4.0 (a Compressed

filesystem for Linux. It uses zlib compression to compress both
files, inodes and directories. Inodes in the system are very small
and all blocks are packed to minimise data overhead. Block sizes
greater than 4K are supported up to a maximum of 1 Mbytes (default
block size 128K). SquashFS 4.0 supports 64 bit filesystems and files
(larger than 4GB), full uid/gid information, hard links and
timestamps.
Squashfs is intended for general read-only filesystem use, for
archival use (i.e. in cases where a .tar.gz file may be used), and in
embedded systems where low overhead is needed. Further information
and tools are available from http://squashfs.sourceforge.net.
If you want to compile this as a module ( = code which can be

SCO, Xenix and Coherent are commercial Unix systems for Intel

here would allow you to read from their floppies and hard disk
partitions.
If you have floppies or hard disk partitions like that, it is likely
that they contain binaries from those other Unix systems; in order
to run these binaries, you will want to install linux-abi which is
a set of kernel modules that lets you run SCO, Xenix, Wyse,
UnixWare, Dell Unix and System V programs under Linux. It is
available via FTP (user: ftp) from
<ftp://ftp.openlinux.org/pub/people/hch/linux-abi/>).
NOTE: that will work only for binaries from Intel-based systems;
PDP ones will have to wait until somebody ports Linux to -11 ;-)
If you only intend to mount files from some other Unix over the
network using NFS, you don't need the System V file system support
(but you need NFS file system support obviously).
Note that this option is generally not needed for floppies, since a

[PATCH] v9fs: Documentation, Makefiles, Configuration OVERVIEW V9FS is a distributed file system for Linux which provides an implementation of the Plan 9 resource sharing protocol 9P. It can be used to share all sorts of resources: static files, synthetic file servers (such as /proc or /sys), devices, and application file servers (such as FUSE). BACKGROUND Plan 9 (http://plan9.bell-labs.com/plan9) is a research operating system and associated applications suite developed by the Computing Science Research Center of AT&T Bell Laboratories (now a part of Lucent Technologies), the same group that developed UNIX , C, and C++. Plan 9 was initially released in 1993 to universities, and then made generally available in 1995. Its core operating systems code laid the foundation for the Inferno Operating System released as a product by Lucent Bell-Labs in 1997. The Inferno venture was the only commercial embodiment of Plan 9 and is currently maintained as a product by Vita Nuova (http://www.vitanuova.com). After updated releases in 2000 and 2002, Plan 9 was open-sourced under the OSI approved Lucent Public License in 2003. The Plan 9 project was started by Ken Thompson and Rob Pike in 1985. Their intent was to explore potential solutions to some of the shortcomings of UNIX in the face of the widespread use of high-speed networks to connect machines. In UNIX, networking was an afterthought and UNIX clusters became little more than a network of stand-alone systems. Plan 9 was designed from first principles as a seamless distributed system with integrated secure network resource sharing. Applications and services were architected in such a way as to allow for implicit distribution across a cluster of systems. Configuring an environment to use remote application components or services in place of their local equivalent could be achieved with a few simple command line instructions. For the most part, application implementations operated independent of the location of their actual resources. Commercial operating systems haven't changed much in the 20 years since Plan 9 was conceived. Network and distributed systems support is provided by a patchwork of middle-ware, with an endless number of packages supplying pieces of the puzzle. Matters are complicated by the use of different complicated protocols for individual services, and separate implementations for kernel and application resources. The V9FS project (http://v9fs.sourceforge.net) is an attempt to bring Plan 9's unified approach to resource sharing to Linux and other operating systems via support for the 9P2000 resource sharing protocol. V9FS HISTORY V9FS was originally developed by Ron Minnich and Maya Gokhale at Los Alamos National Labs (LANL) in 1997. In November of 2001, Greg Watson setup a SourceForge project as a public repository for the code which supported the Linux 2.4 kernel. About a year ago, I picked up the initial attempt Ron Minnich had made to provide 2.6 support and got the code integrated into a 2.6.5 kernel. I then went through a line-for-line re-write attempting to clean-up the code while more closely following the Linux Kernel style guidelines. I co-authored a paper with Ron Minnich on the V9FS Linux support including performance comparisons to NFSv3 using Bonnie and PostMark - this paper appeared at the USENIX/FREENIX 2005 conference in April 2005: ( http://www.usenix.org/events/usenix05/tech/freenix/hensbergen.html ). CALL FOR PARTICIPATION/REQUEST FOR COMMENTS Our 2.6 kernel support is stabilizing and we'd like to begin pursuing its integration into the official kernel tree. We would appreciate any review, comments, critiques, and additions from this community and are actively seeking people to join our project and help us produce something that would be acceptable and useful to the Linux community. STATUS The code is reasonably stable, although there are no doubt corner cases our regression tests haven't discovered yet. It is in regular use by several of the developers and has been tested on x86 and PowerPC (32-bit and 64-bit) in both small and large (LANL cluster) deployments. Our current regression tests include fsx, bonnie, and postmark. It was our intention to keep things as simple as possible for this release -- trying to focus on correctness within the core of the protocol support versus a rich set of features. For example: a more complete security model and cache layer are in the road map, but excluded from this release. Additionally, we have removed support for mmap operations at Al Viro's request. PERFORMANCE Detailed performance numbers and analysis are included in the FREENIX paper, but we show comparable performance to NFSv3 for large file operations based on the Bonnie benchmark, and superior performance for many small file operations based on the PostMark benchmark. Somewhat preliminary graphs (from the FREENIX paper) are available (http://v9fs.sourceforge.net/perf/index.html).

[PATCH] v9fs: Documentation, Makefiles, Configuration OVERVIEW V9FS is a distributed file system for Linux which provides an implementation of the Plan 9 resource sharing protocol 9P. It can be used to share all sorts of resources: static files, synthetic file servers (such as /proc or /sys), devices, and application file servers (such as FUSE). BACKGROUND Plan 9 (http://plan9.bell-labs.com/plan9) is a research operating system and associated applications suite developed by the Computing Science Research Center of AT&T Bell Laboratories (now a part of Lucent Technologies), the same group that developed UNIX , C, and C++. Plan 9 was initially released in 1993 to universities, and then made generally available in 1995. Its core operating systems code laid the foundation for the Inferno Operating System released as a product by Lucent Bell-Labs in 1997. The Inferno venture was the only commercial embodiment of Plan 9 and is currently maintained as a product by Vita Nuova (http://www.vitanuova.com). After updated releases in 2000 and 2002, Plan 9 was open-sourced under the OSI approved Lucent Public License in 2003. The Plan 9 project was started by Ken Thompson and Rob Pike in 1985. Their intent was to explore potential solutions to some of the shortcomings of UNIX in the face of the widespread use of high-speed networks to connect machines. In UNIX, networking was an afterthought and UNIX clusters became little more than a network of stand-alone systems. Plan 9 was designed from first principles as a seamless distributed system with integrated secure network resource sharing. Applications and services were architected in such a way as to allow for implicit distribution across a cluster of systems. Configuring an environment to use remote application components or services in place of their local equivalent could be achieved with a few simple command line instructions. For the most part, application implementations operated independent of the location of their actual resources. Commercial operating systems haven't changed much in the 20 years since Plan 9 was conceived.

If you say Y here, you will get experimental support for
Plan 9 resource sharing via the 9P2000 protocol.
See <http://v9fs.sf.net> for more information.
If unsure, say N.

[PATCH] BLOCK: Make it possible to disable the block layer [try #6] Make it possible to disable the block layer. Not all embedded devices require it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require the block layer to be present. This patch does the following: (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev support. (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls an item that uses the block layer. This includes: (*) Block I/O tracing. (*) Disk partition code. (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS. (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the block layer to do scheduling. Some drivers that use SCSI facilities - such as USB storage - end up disabled indirectly from this. (*) Various block-based device drivers, such as IDE and the old CDROM drivers. (*) MTD blockdev handling and FTL. (*) JFFS - which uses set_bdev_super(), something it could avoid doing by taking a leaf out of JFFS2's book. (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is, however, still used in places, and so is still available. (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and parts of linux/fs.h. (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK. (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK. (*) set_page_dirty() doesn't call __set_page_dirty_buffers() if CONFIG_BLOCK is not enabled. (*) fs/no-block.c is created to hold out-of-line stubs and things that are required when CONFIG_BLOCK is not set: (*) Default blockdev file operations (to give error ENODEV on opening). (*) Makes some /proc changes: (*) /proc/devices does not list any blockdevs. (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK. (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK. (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if given command other than Q_SYNC or if a special device is specified. (*) In init/do_mounts.c, no reference is made to the blockdev routines if CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2. (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return error ENOSYS by way of cond_syscall if so). (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if CONFIG_BLOCK is not set, since they can't then happen.
