Kernel device drivers can register devices by ++name rather than major and minor numbers. These devices will appear in ++devfs automatically, with whatever default ownership and ++protection the driver specified. A daemon (devfsd) can be used to ++override these defaults. Devfs has been in the kernel since 2.3.46. ++ ++NOTE that devfs is entirely optional. If you prefer the old ++disc-based device nodes, then simply leave CONFIG_DEVFS_FS=n (the ++default). In this case, nothing will change. ALSO NOTE that if you do ++enable devfs, the defaults are such that full compatibility is ++maintained with the old devices names. ++ ++There are two aspects to devfs: one is the underlying device ++namespace, which is a namespace just like any mounted filesystem. The ++other aspect is the filesystem code which provides a view of the ++device namespace. The reason I make a distinction is because devfs ++can be mounted many times, with each mount showing the same device ++namespace. Changes made are global to all mounted devfs filesystems. ++Also, because the devfs namespace exists without any devfs mounts, you ++can easily mount the root filesystem by referring to an entry in the ++devfs namespace. ++ ++ ++The cost of devfs is a small increase in kernel code size and memory ++usage. About 7 pages of code (some of that in __init sections) and 72 ++bytes for each entry in the namespace. A modest system has only a ++couple of hundred device entries, so this costs a few more ++pages. Compare this with the suggestion to put /dev on a <a ++href="#why-faq-ramdisc">ramdisc. ++ ++On a typical machine, the cost is under 0.2 percent. On a modest ++system with 64 MBytes of RAM, the cost is under 0.1 percent. The ++accusations of "bloatware" levelled at devfs are not justified. ++ ++----------------------------------------------------------------------------- ++ ++ ++Why do it? ++ ++There are several problems that devfs addresses. Some of these ++problems are more serious than others (depending on your point of ++view), and some can be solved without devfs. However, the totality of ++these problems really calls out for devfs. ++ ++The choice is a patchwork of inefficient user space solutions, which ++are complex and likely to be fragile, or to use a simple and efficient ++devfs which is robust. ++ ++There have been many counter-proposals to devfs, all seeking to ++provide some of the benefits without actually implementing devfs. So ++far there has been an absence of code and no proposed alternative has ++been able to provide all the features that devfs does. Further, ++alternative proposals require far more complexity in user-space (and ++still deliver less functionality than devfs). Some people have the ++mantra of reducing "kernel bloat", but don't consider the effects on ++user-space. ++ ++A good solution limits the total complexity of kernel-space and ++user-space. ++ ++ ++Major&minor allocation ++ ++The existing scheme requires the allocation of major and minor device ++numbers for each and every device. This means that a central ++co-ordinating authority is required to issue these device numbers ++(unless you're developing a "private" device driver), in order to ++preserve uniqueness. Devfs shifts the burden to a namespace. This may ++not seem like a huge benefit, but actually it is. Since driver authors ++will naturally choose a device name which reflects the functionality ++of the device, there is far less potential for namespace conflict. ++Solving this requires a kernel change. ++ ++/dev management ++ ++Because you currently access devices through device nodes, these must ++be created by the system administrator. For standard devices you can ++usually find a MAKEDEV programme which creates all these (hundreds!) ++of nodes. This means that changes in the kernel must be reflected by ++changes in the MAKEDEV programme, or else the system administrator ++creates device nodes by hand. ++ ++The basic problem is that there are two separate databases of ++major and minor numbers. One is in the kernel and one is in /dev (or ++in a MAKEDEV programme, if you want to look at it that way). This is ++duplication of information, which is not good practice. ++Solving this requires a kernel change. ++ ++/dev growth ++ ++A typical /dev has over 1200 nodes! Most of these devices simply don't ++exist because the hardware is not available. A huge /dev increases the ++time to access devices (I'm just referring to the dentry lookup times ++and the time taken to read inodes off disc: the next subsection shows ++some more horrors). ++ ++An example of how big /dev can grow is if we consider SCSI devices: ++ ++host 6 bits (say up to 64 hosts on a really big machine) ++channel 4 bits (say up to 16 SCSI buses per host) ++id 4 bits ++lun 3 bits ++partition 6 bits ++TOTAL 23 bits ++ ++ ++This requires 8 Mega (1024*1024) inodes if we want to store all ++possible device nodes. Even if we scrap everything but id,partition ++and assume a single host adapter with a single SCSI bus and only one ++logical unit per SCSI target (id), that's still 10 bits or 1024 ++inodes. Each VFS inode takes around 256 bytes (kernel 2.1.78), so ++that's 256 kBytes of inode storage on disc (assuming real inodes take ++a similar amount of space as VFS inodes). This is actually not so bad, ++because disc is cheap these days. Embedded systems would care about ++256 kBytes of /dev inodes, but you could argue that embedded systems ++would have hand-tuned /dev directories. I've had to do just that on my ++embedded systems, but I would rather just leave it to devfs. ++ ++Another issue is the time taken to lookup an inode when first ++referenced. Not only does this take time in scanning through a list in ++memory, but also the seek times to read the inodes off disc. ++This could be solved in user-space using a clever programme which ++scanned the kernel logs and deleted /dev entries which are not ++available and created them when they were available. This programme ++would need to be run every time a new module was loaded, which would ++slow things down a lot. ++ ++There is an existing programme called scsidev which will automatically ++create device nodes for SCSI devices. It can do this by scanning files ++in /proc/scsi. Unfortunately, to extend this idea to other device ++nodes would require significant modifications to existing drivers (so ++they too would provide information in /proc). This is a non-trivial ++change (I should know: devfs has had to do something similar). Once ++you go to this much effort, you may as well use devfs itself (which ++also provides this information). Furthermore, such a system would ++likely be implemented in an ad-hoc fashion, as different drivers will ++provide their information in different ways. ++ ++Devfs is much cleaner, because it (naturally) has a uniform mechanism ++to provide this information: the device nodes themselves! ++ ++ ++Node to driver file_operations translation ++ ++There is an important difference between the way disc-based character ++and block nodes and devfs entries make the connection between an entry ++in /dev and the actual device driver. ++ ++With the current 8 bit major and minor numbers the connection between ++disc-based c&b nodes and per-major drivers is done through a ++fixed-length table of 128 entries. The various filesystem types set ++the inode operations for c&b nodes to {chr,blk}dev_inode_operations, ++so when a device is opened a few quick levels of indirection bring us ++to the driver file_operations. ++ ++For miscellaneous character devices a second step is required: there ++is a scan for the driver entry with the same minor number as the file ++that was opened, and the appropriate minor open method is called. This ++scanning is done *every time* you open a device node. Potentially, you ++may be searching through dozens of misc. entries before you find your ++open method. While not an enormous performance overhead, this does ++seem pointless. ++ ++Linux *must* move beyond the 8 bit major and minor barrier, ++somehow. If we simply increase each to 16 bits, then the indexing ++scheme used for major driver lookup becomes untenable, because the ++major tables (one each for character and block devices) would need to ++be 64 k entries long (512 kBytes on x86, 1 MByte for 64 bit ++systems). So we would have to use a scheme like that used for ++miscellaneous character devices, which means the search time goes up ++linearly with the average number of major device drivers on your ++system. Not all "devices" are hardware, some are higher-level drivers ++like KGI, so you can get more "devices" without adding hardware ++You can improve this by creating an ordered (balanced:-) ++binary tree, in which case your search time becomes log(N). ++Alternatively, you can use hashing to speed up the search. ++But why do that search at all if you don't have to? Once again, it ++seems pointless. ++ ++Note that devfs doesn't use the major&minor system. For devfs ++entries, the connection is done when you lookup the /dev entry. When ++devfs_register() is called, an internal table is appended which has ++the entry name and the file_operations. If the dentry cache doesn't ++have the /dev entry already, this internal table is scanned to get the ++file_operations, and an inode is created. If the dentry cache already ++has the entry, there is *no lookup time* (other than the dentry scan ++itself, but we can't avoid that anyway, and besides Linux dentries ++cream other OS's which don't have them:-). Furthermore, the number of ++node entries in a devfs is only the number of available device ++entries, not the number of *conceivable* entries. Even if you remove ++unnecessary entries in a disc-based /dev, the number of conceivable ++entries remains the same: you just limit yourself in order to save ++space. ++ ++Devfs provides a fast connection between a VFS node and the device ++driver, in a scalable way. ++ ++/dev as a system administration tool ++ ++Right now /dev contains a list of conceivable devices, most of which I ++don't have. Devfs only shows those devices available on my ++system. This means that listing /dev is a handy way of checking what ++devices are available. ++ ++Major&minor size ++ ++Existing major and minor numbers are limited to 8 bits each. This is ++now a limiting factor for some drivers, particularly the SCSI disc ++driver, which consumes a single major number. Only 16 discs are ++supported, and each disc may have only 15 partitions. Maybe this isn't ++a problem for you, but some of us are building huge Linux systems with ++disc arrays. With devfs an arbitrary pointer can be associated with ++each device entry, which can be used to give an effective 32 bit ++device identifier (i.e. that's like having a 32 bit minor ++number). Since this is private to the kernel, there are no C library ++compatibility issues which you would have with increasing major and ++minor number sizes. See the section on "Allocation of Device Numbers" ++for details on maintaining compatibility with userspace. ++ ++Solving this requires a kernel change. ++ ++Since writing this, the kernel has been modified so that the SCSI disc ++driver has more major numbers allocated to it and now supports up to ++128 discs. Since these major numbers are non-contiguous (a result of ++unplanned expansion), the implementation is a little more cumbersome ++than originally. ++ ++Just like the changes to IPv4 to fix impending limitations in the ++address space, people find ways around the limitations. In the long ++run, however, solutions like IPv6 or devfs can't be put off forever. ++ ++Read-only root filesystem ++ ++Having your device nodes on the root filesystem means that you can't ++operate properly with a read-only root filesystem. This is because you ++want to change ownerships and protections of tty devices. Existing ++practice prevents you using a CD-ROM as your root filesystem for a ++*real* system. Sure, you can boot off a CD-ROM, but you can't change ++tty ownerships, so it's only good for installing. ++ ++Also, you can't use a shared NFS root filesystem for a cluster of ++discless Linux machines (having tty ownerships changed on a common ++/dev is not good). Nor can you embed your root filesystem in a ++ROM-FS. ++ ++You can get around this by creating a RAMDISC at boot time, making ++an ext2 filesystem in it, mounting it somewhere and copying the ++contents of /dev into it, then unmounting it and mounting it over ++/dev. ++ ++A devfs is a cleaner way of solving this. ++ ++Non-Unix root filesystem ++ ++Non-Unix filesystems (such as NTFS) can't be used for a root ++filesystem because they variously don't support character and block ++special files or symbolic links. You can't have a separate disc-based ++or RAMDISC-based filesystem mounted on /dev because you need device ++nodes before you can mount these. Devfs can be mounted without any ++device nodes. Devlinks won't work because symlinks aren't supported. ++An alternative solution is to use initrd to mount a RAMDISC initial ++root filesystem (which is populated with a minimal set of device ++nodes), and then construct a new /dev in another RAMDISC, and finally ++switch to your non-Unix root filesystem. This requires clever boot ++scripts and a fragile and conceptually complex boot procedure. ++ ++Devfs solves this in a robust and conceptually simple way. ++ ++PTY security ++ ++Current pseudo-tty (pty) devices are owned by root and read-writable ++by everyone. The user of a pty-pair cannot change ++ownership/protections without being suid-root. ++ ++This could be solved with a secure user-space daemon which runs as ++root and does the actual creation of pty-pairs. Such a daemon would ++require modification to *every* programme that wants to use this new ++mechanism. It also slows down creation of pty-pairs. ++ ++An alternative is to create a new open_pty() syscall which does much ++the same thing as the user-space daemon. Once again, this requires ++modifications to pty-handling programmes. ++ ++The devfs solution allows a device driver to "tag" certain device ++files so that when an unopened device is opened, the ownerships are ++changed to the current euid and egid of the opening process, and the ++protections are changed to the default registered by the driver. When ++the device is closed ownership is set back to root and protections are ++set back to read-write for everybody. No programme need be changed. ++The devpts filesystem provides this auto-ownership feature for Unix98 ++ptys. It doesn't support old-style pty devices, nor does it have all ++the other features of devfs. ++ ++Intelligent device management ++ ++Devfs implements a simple yet powerful protocol for communication with ++a device management daemon (devfsd) which runs in user space. It is ++possible to send a message (either synchronously or asynchronously) to ++devfsd on any event, such as registration/unregistration of device ++entries, opening and closing devices, looking up inodes, scanning ++directories and more. This has many possibilities. Some of these are ++already implemented. See: ++ ++ ++http://www.atnf.csiro.au/~rgooch/linux/ ++ ++Device entry registration events can be used by devfsd to change ++permissions of newly-created device nodes. This is one mechanism to ++control device permissions. ++ ++Device entry registration/unregistration events can be used to run ++programmes or scripts. This can be used to provide automatic mounting ++of filesystems when a new block device media is inserted into the ++drive. ++ ++Asynchronous device open and close events can be used to implement ++clever permissions management. For example, the default permissions on ++/dev/dsp do not allow everybody to read from the device. This is ++sensible, as you don't want some remote user recording what you say at ++your console. However, the console user is also prevented from ++recording. This behaviour is not desirable. With asynchronous device ++open and close events, you can have devfsd run a programme or script ++when console devices are opened to change the ownerships for *other* ++device nodes (such as /dev/dsp). On closure, you can run a different ++script to restore permissions. An advantage of this scheme over ++modifying the C library tty handling is that this works even if your ++programme crashes (how many times have you seen the utmp database with ++lingering entries for non-existent logins?). ++ ++Synchronous device open events can be used to perform intelligent ++device access protections. Before the device driver open() method is ++called, the daemon must first validate the open attempt, by running an ++external programme or script. This is far more flexible than access ++control lists, as access can be determined on the basis of other ++system conditions instead of just the UID and GID. ++ ++Inode lookup events can be used to authenticate module autoload ++requests. Instead of using kmod directly, the event is sent to ++devfsd which can implement an arbitrary authentication before loading ++the module itself. ++ ++Inode lookup events can also be used to construct arbitrary ++namespaces, without having to resort to populating devfs with symlinks ++to devices that don't exist. ++ ++Speculative Device Scanning ++ ++Consider an application (like cdparanoia) that wants to find all ++CD-ROM devices on the system (SCSI, IDE and other types), whether or ++not their respective modules are loaded. The application must ++speculatively open certain device nodes (such as /dev/sr0 for the SCSI ++CD-ROMs) in order to make sure the module is loaded. This requires ++that all Linux distributions follow the standard device naming scheme ++(last time I looked RedHat did things differently). Devfs solves the ++naming problem. ++ ++The same application also wants to see which devices are actually ++available on the system. With the existing system it needs to read the ++/dev directory and speculatively open each /dev/sr* device to ++determine if the device exists or not. With a large /dev this is an ++inefficient operation, especially if there are many /dev/sr* nodes. A ++solution like scsidev could reduce the number of /dev/sr* entries (but ++of course that also requires all that inefficient directory scanning). ++ ++With devfs, the application can open the /dev/sr directory ++(which triggers the module autoloading if required), and proceed to ++read /dev/sr. Since only the available devices will have ++entries, there are no inefficencies in directory scanning or device ++openings. ++ ++----------------------------------------------------------------------------- ++ ++Who else does it? ++ ++FreeBSD has a devfs implementation. Solaris and AIX each have a ++pseudo-devfs (something akin to scsidev but for all devices, with some ++unspecified kernel support). BeOS, Plan9 and QNX also have it. SGI's ++IRIX 6.4 and above also have a device filesystem. ++ ++While we shouldn't just automatically do something because others do ++it, we should not ignore the work of others either. FreeBSD has a lot ++of competent people working on it, so their opinion should not be ++blithely ignored. ++ ++----------------------------------------------------------------------------- ++ ++ ++How it works ++ ++Registering device entries ++ ++For every entry (device node) in a devfs-based /dev a driver must call ++devfs_register(). This adds the name of the device entry, the ++file_operations structure pointer and a few other things to an ++internal table. Device entries may be added and removed at any ++time. When a device entry is registered, it automagically appears in ++any mounted devfs'. ++ ++Inode lookup ++ ++When a lookup operation on an entry is performed and if there is no ++driver information for that entry devfs will attempt to call ++devfsd. If still no driver information can be found then a negative ++dentry is yielded and the next stage operation will be called by the ++VFS (such as create() or mknod() inode methods). If driver information ++can be found, an inode is created (if one does not exist already) and ++all is well. ++ ++Manually creating device nodes ++ ++The mknod() method allows you to create an ordinary named pipe in the ++devfs, or you can create a character or block special inode if one ++does not already exist. You may wish to create a character or block ++special inode so that you can set permissions and ownership. Later, if ++a device driver registers an entry with the same name, the ++permissions, ownership and times are retained. This is how you can set ++the protections on a device even before the driver is loaded. Once you ++create an inode it appears in the directory listing. ++ ++Unregistering device entries ++ ++A device driver calls devfs_unregister() to unregister an entry. ++ ++Chroot() gaols ++ ++2.2.x kernels ++ ++The semantics of inode creation are different when devfs is mounted ++with the "explicit" option. Now, when a device entry is registered, it ++will not appear until you use mknod() to create the device. It doesn't ++matter if you mknod() before or after the device is registered with ++devfs_register(). The purpose of this behaviour is to support ++chroot(2) gaols, where you want to mount a minimal devfs inside the ++gaol. Only the devices you specifically want to be available (through ++your mknod() setup) will be accessible. ++ ++2.4.x kernels ++ ++As of kernel 2.3.99, the VFS has had the ability to rebind parts of ++the global filesystem namespace into another part of the namespace. ++This now works even at the leaf-node level, which means that ++individual files and device nodes may be bound into other parts of the ++namespace. This is like making links, but better, because it works ++across filesystems (unlike hard links) and works through chroot() ++gaols (unlike symbolic links). ++ ++Because of these improvements to the VFS, the multi-mount capability ++in devfs is no longer needed. The administrator may create a minimal ++device tree inside a chroot(2) gaol by using VFS bindings. As this ++provides most of the features of the devfs multi-mount capability, I ++removed the multi-mount support code (after issuing an RFC). This ++yielded code size reductions and simplifications. ++ ++If you want to construct a minimal chroot() gaol, the following ++command should suffice: ++ ++mount --bind /dev/null /gaol/dev/null ++ ++ ++Repeat for other device nodes you want to expose. Simple! ++ ++----------------------------------------------------------------------------- ++ ++ ++Operational issues ++ ++ ++Instructions for the impatient ++ ++Nobody likes reading documentation. People just want to get in there ++and play. So this section tells you quickly the steps you need to take ++to run with devfs mounted over /dev. Skip these steps and you will end ++up with a nearly unbootable system. Subsequent sections describe the ++issues in more detail, and discuss non-essential configuration ++options. ++ ++Devfsd ++OK, if you're reading this, I assume you want to play with ++devfs. First you should ensure that /usr/src/linux contains a ++recent kernel source tree. Then you need to compile devfsd, the device ++management daemon, available at ++ ++http://www.atnf.csiro.au/~rgooch/linux/. ++Because the kernel has a naming scheme ++which is quite different from the old naming scheme, you need to ++install devfsd so that software and configuration files that use the ++old naming scheme will not break. ++ ++Compile and install devfsd. You will be provided with a default ++configuration file /etc/devfsd.conf which will provide ++compatibility symlinks for the old naming scheme. Don't change this ++config file unless you know what you're doing. Even if you think you ++do know what you're doing, don't change it until you've followed all ++the steps below and booted a devfs-enabled system and verified that it ++works. ++ ++Now edit your main system boot script so that devfsd is started at the ++very beginning (before any filesystem ++checks). /etc/rc.d/rc.sysinit is often the main boot script ++on systems with SysV-style boot scripts. On systems with BSD-style ++boot scripts it is often /etc/rc. Also check ++/sbin/rc. ++ ++NOTE that the line you put into the boot ++script should be exactly: ++ ++/sbin/devfsd /dev ++ ++DO NOT use some special daemon-launching ++programme, otherwise the boot script may not wait for devfsd to finish ++initialising. ++ ++System Libraries ++There may still be some problems because of broken software making ++assumptions about device names. In particular, some software does not ++handle devices which are symbolic links. If you are running a libc 5 ++based system, install libc 5.4.44 (if you have libc 5.4.46, go back to ++libc 5.4.44, which is actually correct). If you are running a glibc ++based system, make sure you have glibc 2.1.3 or later. ++ ++/etc/securetty ++PAM (Pluggable Authentication Modules) is supposed to be a flexible ++mechanism for providing better user authentication and access to ++services. Unfortunately, it's also fragile, complex and undocumented ++(check out RedHat 6.1, and probably other distributions as well). PAM ++has problems with symbolic links. Append the following lines to your ++/etc/securetty file: ++ ++vc/1 ++vc/2 ++vc/3 ++vc/4 ++vc/5 ++vc/6 ++vc/7 ++vc/8 ++ ++This will not weaken security. If you have a version of util-linux ++earlier than 2.10.h, please upgrade to 2.10.h or later. If you ++absolutely cannot upgrade, then also append the following lines to ++your /etc/securetty file: ++ ++1 ++2 ++3 ++4 ++5 ++6 ++7 ++8 ++ ++This may potentially weaken security by allowing root logins over the ++network (a password is still required, though). However, since there ++are problems with dealing with symlinks, I'm suspicious of the level ++of security offered in any case. ++ ++XFree86 ++While not essential, it's probably a good idea to upgrade to XFree86 ++4.0, as patches went in to make it more devfs-friendly. If you don't, ++you'll probably need to apply the following patch to ++/etc/security/console.perms so that ordinary users can run ++startx. Note that not all distributions have this file (e.g. Debian), ++so if it's not present, don't worry about it. ++ ++--- /etc/security/console.perms.orig Sat Apr 17 16:26:47 1999 +++++ /etc/security/console.perms Fri Feb 25 23:53:55 2000 ++@@ -14,7 +14,7 @@ ++ # man 5 console.perms ++ ++ # file classes -- these are regular expressions ++-<console>=tty[0-9][0-9]* :[0-9]\.[0-9] :[0-9] +++<console>=tty[0-9][0-9]* vc/[0-9][0-9]* :[0-9]\.[0-9] :[0-9] ++ ++ # device classes -- these are shell-style globs ++ <floppy>=/dev/fd[0-1]* ++ ++If the patch does not apply, then change the line: ++ ++<console>=tty[0-9][0-9]* :[0-9]\.[0-9] :[0-9] ++ ++with: ++ ++<console>=tty[0-9][0-9]* vc/[0-9][0-9]* :[0-9]\.[0-9] :[0-9] ++ ++ ++Disable devpts ++I've had a report of devpts mounted on /dev/pts not working ++correctly. Since devfs will also manage /dev/pts, there is no ++need to mount devpts as well. You should either edit your ++/etc/fstab so devpts is not mounted, or disable devpts from ++your kernel configuration. ++ ++Unsupported drivers ++Not all drivers have devfs support. If you depend on one of these ++drivers, you will need to create a script or tarfile that you can use ++at boot time to create device nodes as appropriate. There is a ++section which describes this. Another ++section lists the drivers which have ++devfs support. ++ ++/dev/mouse ++ ++Many disributions configure /dev/mouse to be the mouse device ++for XFree86 and GPM. I actually think this is a bad idea, because it ++adds another level of indirection. When looking at a config file, if ++you see /dev/mouse you're left wondering which mouse ++is being referred to. Hence I recommend putting the actual mouse ++device (for example /dev/psaux) into your ++/etc/X11/XF86Config file (and similarly for the GPM ++configuration file). ++ ++Alternatively, use the same technique used for unsupported drivers ++described above. ++ ++The Kernel ++Finally, you need to make sure devfs is compiled into your kernel. Set ++CONFIG_EXPERIMENTAL=y, CONFIG_DEVFS_FS=y and CONFIG_DEVFS_MOUNT=y by ++using favourite configuration tool (i.e. make config or ++make xconfig) and then make clean and then recompile your kernel and ++modules. At boot, devfs will be mounted onto /dev. ++ ++If you encounter problems booting (for example if you forgot a ++configuration step), you can pass devfs=nomount at the kernel ++boot command line. This will prevent the kernel from mounting devfs at ++boot time onto /dev. ++ ++In general, a kernel built with CONFIG_DEVFS_FS=y but without mounting ++devfs onto /dev is completely safe, and requires no ++configuration changes. One exception to take note of is when ++LABEL= directives are used in /etc/fstab. In this ++case you will be unable to boot properly. This is because the ++mount(8) programme uses /proc/partitions as part of ++the volume label search process, and the device names it finds are not ++available, because setting CONFIG_DEVFS_FS=y changes the names in ++/proc/partitions, irrespective of whether devfs is mounted. ++ ++Now you've finished all the steps required. You're now ready to boot ++your shiny new kernel. Enjoy. ++ ++Changing the configuration ++ ++OK, you've now booted a devfs-enabled system, and everything works. ++Now you may feel like changing the configuration (common targets are ++/etc/fstab and /etc/devfsd.conf). Since you have a ++system that works, if you make any changes and it doesn't work, you ++now know that you only have to restore your configuration files to the ++default and it will work again. ++ ++ ++Permissions persistence across reboots ++ ++If you don't use mknod(2) to create a device file, nor use chmod(2) or ++chown(2) to change the ownerships/permissions, the inode ctime will ++remain at 0 (the epoch, 12 am, 1-JAN-1970, GMT). Anything with a ctime ++later than this has had it's ownership/permissions changed. Hence, a ++simple script or programme may be used to tar up all changed inodes, ++prior to shutdown. Although effective, many consider this approach a ++kludge. ++ ++A much better approach is to use devfsd to save and restore ++permissions. It may be configured to record changes in permissions and ++will save them in a database (in fact a directory tree), and restore ++these upon boot. This is an efficient method and results in immediate ++saving of current permissions (unlike the tar approach, which saves ++permissions at some unspecified future time). ++ ++The default configuration file supplied with devfsd has config entries ++which you may uncomment to enable persistence management. ++ ++If you decide to use the tar approach anyway, be aware that tar will ++first unlink(2) an inode before creating a new device node. The ++unlink(2) has the effect of breaking the connection between a devfs ++entry and the device driver. If you use the "devfs=only" boot option, ++you lose access to the device driver, requiring you to reload the ++module. I consider this a bug in tar (there is no real need to ++unlink(2) the inode first). ++ ++Alternatively, you can use devfsd to provide more sophisticated ++management of device permissions. You can use devfsd to store ++permissions for whole groups of devices with a single configuration ++entry, rather than the conventional single entry per device entry. ++ ++Permissions database stored in mounted-over /dev ++ ++If you wish to save and restore your device permissions into the ++disc-based /dev while still mounting devfs onto /dev ++you may do so. This requires a 2.4.x kernel (in fact, 2.3.99 or ++later), which has the VFS binding facility. You need to do the ++following to set this up: ++ ++ ++ ++make sure the kernel does not mount devfs at boot time ++ ++ ++make sure you have a correct /dev/console entry in your ++root file-system (where your disc-based /dev lives) ++ ++create the /dev-state directory ++ ++ ++add the following lines near the very beginning of your boot ++scripts: ++ ++mount --bind /dev /dev-state ++mount -t devfs none /dev ++devfsd /dev ++ ++ ++ ++ ++add the following lines to your /etc/devfsd.conf file: ++ ++REGISTER ^pt[sy] IGNORE ++CREATE ^pt[sy] IGNORE ++CHANGE ^pt[sy] IGNORE ++DELETE ^pt[sy] IGNORE ++REGISTER .* COPY /dev-state/$devname $devpath ++CREATE .* COPY $devpath /dev-state/$devname ++CHANGE .* COPY $devpath /dev-state/$devname ++DELETE .* CFUNCTION GLOBAL unlink /dev-state/$devname ++RESTORE /dev-state ++ ++Note that the sample devfsd.conf file contains these lines, ++as well as other sample configurations you may find useful. See the ++devfsd distribution ++ ++ ++reboot. ++ ++ ++ ++ ++Permissions database stored in normal directory ++ ++If you are using an older kernel which doesn't support VFS binding, ++then you won't be able to have the permissions database in a ++mounted-over /dev. However, you can still use a regular ++directory to store the database. The sample /etc/devfsd.conf ++file above may still be used. You will need to create the ++/dev-state directory prior to installing devfsd. If you have ++old permissions in /dev, then just copy (or move) the device ++nodes over to the new directory. ++ ++Which method is better? ++ ++The best method is to have the permissions database stored in the ++mounted-over /dev. This is because you will not need to copy ++device nodes over to /dev-state, and because it allows you to ++switch between devfs and non-devfs kernels, without requiring you to ++copy permissions between /dev-state (for devfs) and ++/dev (for non-devfs). ++ ++ ++Dealing with drivers without devfs support ++ ++Currently, not all device drivers in the kernel have been modified to ++use devfs. Device drivers which do not yet have devfs support will not ++automagically appear in devfs. The simplest way to create device nodes ++for these drivers is to unpack a tarfile containing the required ++device nodes. You can do this in your boot scripts. All your drivers ++will now work as before. ++ ++Hopefully for most people devfs will have enough support so that they ++can mount devfs directly over /dev without losing most functionality ++(i.e. losing access to various devices). As of 22-JAN-1998 (devfs ++patch version 10) I am now running this way. All the devices I have ++are available in devfs, so I don't lose anything. ++ ++WARNING: if your configuration requires the old-style device names ++(i.e. /dev/hda1 or /dev/sda1), you must install devfsd and configure ++it to maintain compatibility entries. It is almost certain that you ++will require this. Note that the kernel creates a compatibility entry ++for the root device, so you don't need initrd. ++ ++Note that you no longer need to mount devpts if you use Unix98 PTYs, ++as devfs can manage /dev/pts itself. This saves you some RAM, as you ++don't need to compile and install devpts. Note that some versions of ++glibc have a bug with Unix98 pty handling on devfs systems. Contact ++the glibc maintainers for a fix. Glibc 2.1.3 has the fix. ++ ++Note also that apart from editing /etc/fstab, other things will need ++to be changed if you *don't* install devfsd. Some software (like the X ++server) hard-wire device names in their source. It really is much ++easier to install devfsd so that compatibility entries are created. ++You can then slowly migrate your system to using the new device names ++(for example, by starting with /etc/fstab), and then limiting the ++compatibility entries that devfsd creates. ++ ++IF YOU CONFIGURE TO MOUNT DEVFS AT BOOT, MAKE SURE YOU INSTALL DEVFSD ++BEFORE YOU BOOT A DEVFS-ENABLED KERNEL! ++ ++Now that devfs has gone into the 2.3.46 kernel, I'm getting a lot of ++reports back. Many of these are because people are trying to run ++without devfsd, and hence some things break. Please just run devfsd if ++things break. I want to concentrate on real bugs rather than ++misconfiguration problems at the moment. If people are willing to fix ++bugs/false assumptions in other code (i.e. glibc, X server) and submit ++that to the respective maintainers, that would be great. ++ ++ ++All the way with Devfs ++ ++The devfs kernel patch creates a rationalised device tree. As stated ++above, if you want to keep using the old /dev naming scheme, ++you just need to configure devfsd appopriately (see the man ++page). People who prefer the old names can ignore this section. For ++those of us who like the rationalised names and an uncluttered ++/dev, read on. ++ ++If you don't run devfsd, or don't enable compatibility entry ++management, then you will have to configure your system to use the new ++names. For example, you will then need to edit your ++/etc/fstab to use the new disc naming scheme. If you want to ++be able to boot non-devfs kernels, you will need compatibility ++symlinks in the underlying disc-based /dev pointing back to ++the old-style names for when you boot a kernel without devfs. ++ ++You can selectively decide which devices you want compatibility ++entries for. For example, you may only want compatibility entries for ++BSD pseudo-terminal devices (otherwise you'll have to patch you C ++library or use Unix98 ptys instead). It's just a matter of putting in ++the correct regular expression into /dev/devfsd.conf. ++ ++There are other choices of naming schemes that you may prefer. For ++example, I don't use the kernel-supplied ++names, because they are too verbose. A common misconception is ++that the kernel-supplied names are meant to be used directly in ++configuration files. This is not the case. They are designed to ++reflect the layout of the devices attached and to provide easy ++classification. ++ ++If you like the kernel-supplied names, that's fine. If you don't then ++you should be using devfsd to construct a namespace more to your ++liking. Devfsd has built-in code to construct a ++namespace that is both logical and easy to ++manage. In essence, it creates a convenient abbreviation of the ++kernel-supplied namespace. ++ ++You are of course free to build your own namespace. Devfsd has all the ++infrastructure required to make this easy for you. All you need do is ++write a script. You can even write some C code and devfsd can load the ++shared object as a callable extension. ++ ++ ++Other Issues ++ ++The init programme ++Another thing to take note of is whether your init programme ++creates a Unix socket /dev/telinit. Some versions of init ++create /dev/telinit so that the telinit programme can ++communicate with the init process. If you have such a system you need ++to make sure that devfs is mounted over /dev *before* init ++starts. In other words, you can't leave the mounting of devfs to ++/etc/rc, since this is executed after init. Other ++versions of init require a named pipe /dev/initctl ++which must exist *before* init starts. Once again, you need to ++mount devfs and then create the named pipe *before* init ++starts. ++ ++The default behaviour now is not to mount devfs onto /dev at ++boot time for 2.3.x and later kernels. You can correct this with the ++"devfs=mount" boot option. This solves any problems with init, ++and also prevents the dreaded: ++ ++Cannot open initial console ++ ++message. For 2.2.x kernels where you need to apply the devfs patch, ++the default is to mount. ++ ++If you have automatic mounting of devfs onto /dev then you ++may need to create /dev/initctl in your boot scripts. The ++following lines should suffice: ++ ++mknod /dev/initctl p ++kill -SIGUSR1 1 # tell init that /dev/initctl now exists ++ ++Alternatively, if you don't want the kernel to mount devfs onto ++/dev then you could use the following procedure is a ++guideline for how to get around /dev/initctl problems: ++ ++# cd /sbin ++# mv init init.real ++# cat > init ++#! /bin/sh ++mount -n -t devfs none /dev ++mknod /dev/initctl p ++exec /sbin/init.real $* ++[control-D] ++# chmod a+x init ++ ++Note that newer versions of init create /dev/initctl ++automatically, so you don't have to worry about this. ++ ++Module autoloading ++You will need to configure devfsd to enable module ++autoloading. The following lines should be placed in your ++/etc/devfsd.conf file: ++ ++LOOKUP .* MODLOAD ++ ++ ++As of devfsd-v1.3.10, a generic /etc/modules.devfs ++configuration file is installed, which is used by the MODLOAD ++action. This should be sufficient for most configurations. If you ++require further configuration, edit your /etc/modules.conf ++file. The way module autoloading work with devfs is: ++ ++ ++a process attempts to lookup a device node (e.g. /dev/fred) ++ ++ ++if that device node does not exist, the full pathname is passed to ++devfsd as a string ++ ++ ++devfsd will pass the string to the modprobe programme (provided the ++configuration line shown above is present), and specifies that ++/etc/modules.devfs is the configuration file ++ ++ ++/etc/modules.devfs includes /etc/modules.conf to ++access local configurations ++ ++modprobe will search it's configuration files, looking for an alias ++that translates the pathname into a module name ++ ++ ++the translated pathname is then used to load the module. ++ ++ ++If you wanted a lookup of /dev/fred to load the ++mymod module, you would require the following configuration ++line in /etc/modules.conf: ++ ++alias /dev/fred mymod ++ ++The /etc/modules.devfs configuration file provides many such ++aliases for standard device names. If you look closely at this file, ++you will note that some modules require multiple alias configuration ++lines. This is required to support module autoloading for old and new ++device names. ++ ++Mounting root off a devfs device ++If you wish to mount root off a devfs device when you pass the ++"devfs=only" boot option, then you need to pass in the ++"root=<device>" option to the kernel when booting. If you use ++LILO, then you must have this in lilo.conf: ++ ++append = "root=<device>" ++ ++Surprised? Yep, so was I. It turns out if you have (as most people ++do): ++ ++root = <device> ++ ++ ++then LILO will determine the device number of <device> and will ++write that device number into a special place in the kernel image ++before starting the kernel, and the kernel will use that device number ++to mount the root filesystem. So, using the "append" variety ensures ++that LILO passes the root filesystem device as a string, which devfs ++can then use. ++ ++Note that this isn't an issue if you don't pass "devfs=only". ++ ++TTY issues ++The ttyname(3) function in some versions of the C library makes ++false assumptions about device entries which are symbolic links. The ++tty(1) programme is one that depends on this function. I've ++written a patch to libc 5.4.43 which fixes this. This has been ++included in libc 5.4.44 and a similar fix is in glibc 2.1.3. ++ ++ ++Kernel Naming Scheme ++ ++The kernel provides a default naming scheme. This scheme is designed ++to make it easy to search for specific devices or device types, and to ++view the available devices. Some device types (such as hard discs), ++have a directory of entries, making it easy to see what devices of ++that class are available. Often, the entries are symbolic links into a ++directory tree that reflects the topology of available devices. The ++topological tree is useful for finding how your devices are arranged. ++ ++Below is a list of the naming schemes for the most common drivers. A ++list of reserved device names is ++available for reference. Please send email to ++rgooch@atnf.csiro.au to obtain an allocation. Please be ++patient (the maintainer is busy). An alternative name may be allocated ++instead of the requested name, at the discretion of the maintainer. ++ ++Disc Devices ++ ++All discs, whether SCSI, IDE or whatever, are placed under the ++/dev/discs hierarchy: ++ ++ /dev/discs/disc0 first disc ++ /dev/discs/disc1 second disc ++ ++ ++Each of these entries is a symbolic link to the directory for that ++device.

The device directory contains: ++ ++ mt for mode 0 ++ mtl for mode 1 ++ mtm for mode 2 ++ mta for mode 3 ++ mtn for mode 0, no rewind ++ mtln for mode 1, no rewind ++ mtmn for mode 2, no rewind ++ mtan for mode 3, no rewind ++ ++ ++SCSI Devices ++ ++To uniquely identify any SCSI device requires the following ++information: ++ ++ controller (host adapter) ++ bus (SCSI channel) ++ target (SCSI ID) ++ unit (Logical Unit Number) ++ ++ ++All SCSI devices are placed under /dev/scsi (assuming devfs ++is mounted on /dev).

In some ++cases, the kernel-supplied naming scheme is quite convenient, so ++devfsd does not provide another naming scheme. The convenience names ++that devfsd creates are in fact the same names as the original devfs ++kernel patch created (before Linus mandated the Big Name ++Change). These are referred to as "new compatibility entries". ++ ++In order to configure devfsd to create these convenience names, the ++following lines should be placed in your /etc/devfsd.conf: ++ ++REGISTER .* MKNEWCOMPAT ++UNREGISTER .* RMNEWCOMPAT ++ ++This will cause devfsd to create (and destroy) symbolic links which ++point to the kernel-supplied names. ++ ++SCSI Hard Discs ++ ++All SCSI discs are placed under /dev/sd (assuming devfs is ++mounted on /dev).

However, there are a number of userspace programmes that use ++the device number as a unique handle for a device. An example is the ++find programme, which uses device numbers to determine whether ++an inode is on a different filesystem than another inode. The device ++number used is the one for the block device which a filesystem is ++using. To preserve compatibility with userspace programmes, block ++devices using devfs need to have unique device numbers allocated to ++them. Furthermore, POSIX specifies device numbers, so some kind of ++device number needs to be presented to userspace. ++ ++The simplest option (especially when porting drivers to devfs) is to ++keep using the old major and minor numbers. Devfs will take whatever ++values are given for major&minor and pass them onto userspace. ++ ++This device number is a 16 bit number, so this leaves plenty of space ++for large numbers of discs and partitions. This scheme can also be ++used for character devices, in particular the tty devices, which are ++currently limited to 256 pseudo-ttys (this limits the total number of ++simultaneous xterms and remote logins). Note that the device number ++is limited to the range 36864-61439 (majors 144-239), in order to ++avoid any possible conflicts with existing official allocations. ++ ++Please note that using dynamically allocated block device numbers may ++break the NFS daemons (both user and kernel mode), which expect dev_t ++for a given device to be constant over the lifetime of remote mounts. ++ ++A final note on this scheme: since it doesn't increase the size of ++device numbers, there are no compatibility issues with userspace. ++ ++----------------------------------------------------------------------------- ++ ++ ++Questions and Answers ++ ++ ++Making things work ++Alternatives to devfs ++What I don't like about devfs ++How to report bugs ++Strange kernel messages ++Compilation problems with devfsd ++ ++ ++ ++Making things work ++ ++Here are some common questions and answers. ++ ++ ++ ++Devfsd doesn't start ++ ++Make sure you have compiled and installed devfsd ++Make sure devfsd is being started from your boot ++scripts ++Make sure you have configured your kernel to enable devfs (see ++below) ++Make sure devfs is mounted (see below) ++ ++ ++Devfsd is not managing all my permissions ++ ++Make sure you are capturing the appropriate events. For example, ++device entries created by the kernel generate REGISTER events, ++but those created by devfsd generate CREATE events. ++ ++ ++Devfsd is not capturing all REGISTER events ++ ++See the previous entry: you may need to capture CREATE events. ++ ++ ++X will not start ++ ++Make sure you followed the steps ++outlined above. ++ ++ ++Why don't my network devices appear in devfs? ++ ++This is not a bug. Network devices have their own, completely separate ++namespace. They are accessed via socket(2) and ++setsockopt(2) calls, and thus require no device nodes. I have ++raised the possibilty of moving network devices into the device ++namespace, but have had no response. ++ ++ ++How can I test if I have devfs compiled into my kernel? ++ ++All filesystems built-in or currently loaded are listed in ++/proc/filesystems. If you see a devfs entry, then ++you know that devfs was compiled into your kernel. If you have ++correctly configured and rebuilt your kernel, then devfs will be ++built-in. If you think you've configured it in, but ++/proc/filesystems doesn't show it, you've made a mistake. ++Common mistakes include: ++ ++Using a 2.2.x kernel without applying the devfs patch (if you ++don't know how to patch your kernel, use 2.4.x instead, don't bother ++asking me how to patch) ++Forgetting to set CONFIG_EXPERIMENTAL=y ++Forgetting to set CONFIG_DEVFS_FS=y ++Forgetting to set CONFIG_DEVFS_MOUNT=y (if you want devfs ++to be automatically mounted at boot) ++Editing your .config manually, instead of using make ++config or make xconfig ++Forgetting to run make dep; make clean after changing the ++configuration and before compiling ++Forgetting to compile your kernel and modules ++Forgetting to install your kernel ++Forgetting to install your modules ++ ++Please check twice that you've done all these steps before sending in ++a bug report. ++ ++ ++ ++How can I test if devfs is mounted on /dev? ++ ++The device filesystem will always create an entry called ++".devfsd", which is used to communicate with the daemon. Even ++if the daemon is not running, this entry will exist. Testing for the ++existence of this entry is the approved method of determining if devfs ++is mounted or not. Note that the type of entry (i.e. regular file, ++character device, named pipe, etc.) may change without notice. Only ++the existence of the entry should be relied upon. ++ ++ ++When I start devfsd, I see the error: ++Error opening file: ".devfsd" No such file or directory? ++ ++This means that devfs is not mounted. Make sure you have devfs mounted. ++ ++ ++How do I mount devfs? ++ ++First make sure you have devfs compiled into your kernel (see ++above). Then you will either need to: ++ ++set CONFIG_DEVFS_MOUNT=y in your kernel config ++pass devfs=mount to your boot loader ++mount devfs manually in your boot scripts with: ++mount -t none devfs /dev ++ ++ ++ ++Mount by volume LABEL=<label> doesn't work with ++devfs ++ ++Most probably you are not mounting devfs onto /dev. What ++happens is that if your kernel config has CONFIG_DEVFS_FS=y ++then the contents of /proc/partitions will have the devfs ++names (such as scsi/host0/bus0/target0/lun0/part1). The ++contents of /proc/partitions are used by mount(8) when ++mounting by volume label. If devfs is not mounted on /dev, ++then mount(8) will fail to find devices. The solution is to ++make sure that devfs is mounted on /dev. See above for how to ++do that. ++ ++ ++I have extra or incorrect entries in /dev ++ ++You may have stale entries in your dev-state area. Check for a ++RESTORE configuration line in your devfsd configuration ++(typically /etc/devfsd.conf). If you have this line, check ++the contents of the specified directory for stale entries. Remove ++any entries which are incorrect, then reboot. ++ ++ ++I get "Unable to open initial console" messages at boot ++ ++This usually happens when you don't have devfs automounted onto ++/dev at boot time, and there is no valid ++/dev/console entry on your root file-system. Create a valid ++/dev/console device node. ++ ++ ++ ++ ++ ++Alternatives to devfs ++ ++I've attempted to collate all the anti-devfs proposals and explain ++their limitations. Under construction. ++ ++ ++Why not just pass device create/remove events to a daemon? ++ ++Here the suggestion is to develop an API in the kernel so that devices ++can register create and remove events, and a daemon listens for those ++events. The daemon would then populate/depopulate /dev (which ++resides on disc). ++ ++This has several limitations: ++ ++ ++it only works for modules loaded and unloaded (or devices inserted ++and removed) after the kernel has finished booting. Without a database ++of events, there is no way the daemon could fully populate ++/dev ++ ++ ++if you add a database to this scheme, the question is then how to ++present that database to user-space. If you make it a list of strings ++with embedded event codes which are passed through a pipe to the ++daemon, then this is only of use to the daemon. I would argue that the ++natural way to present this data is via a filesystem (since many of ++the events will be of a hierarchical nature), such as devfs. ++Presenting the data as a filesystem makes it easy for the user to see ++what is available and also makes it easy to write scripts to scan the ++"database" ++ ++ ++the tight binding between device nodes and drivers is no longer ++possible (requiring the otherwise perfectly avoidable ++table lookups) ++ ++ ++you cannot catch inode lookup events on /dev which means ++that module autoloading requires device nodes to be created. This is a ++problem, particularly for drivers where only a few inodes are created ++from a potentially large set ++ ++ ++this technique can't be used when the root FS is mounted ++read-only ++ ++ ++ ++ ++Just implement a better scsidev ++ ++This suggestion involves taking the scsidev programme and ++extending it to scan for all devices, not just SCSI devices. The ++scsidev programme works by scanning /proc/scsi ++ ++Problems: ++ ++ ++the kernel does not currently provide a list of all devices ++available. Not all drivers register entries in /proc or ++generate kernel messages ++ ++ ++there is no uniform mechanism to register devices other than the ++devfs API ++ ++ ++implementing such an API is then the same as the ++proposal above ++ ++ ++ ++ ++Put /dev on a ramdisc ++ ++This suggestion involves creating a ramdisc and populating it with ++device nodes and then mounting it over /dev. ++ ++Problems: ++ ++ ++ ++this doesn't help when mounting the root filesystem, since you ++still need a device node to do that ++ ++ ++if you want to use this technique for the root device node as ++well, you need to use initrd. This complicates the booting sequence ++and makes it significantly harder to administer and configure. The ++initrd is essentially opaque, robbing the system administrator of easy ++configuration ++ ++ ++insufficient information is available to correctly populate the ++ramdisc. So we come back to the ++proposal above to "solve" this ++ ++ ++a ramdisc-based solution would take more kernel memory, since the ++backing store would be (at best) normal VFS inodes and dentries, which ++take 284 bytes and 112 bytes, respectively, for each entry. Compare ++that to 72 bytes for devfs ++ ++ ++ ++ ++Do nothing: there's no problem ++ ++Sometimes people can be heard to claim that the existing scheme is ++fine. This is what they're ignoring: ++ ++ ++device number size (8 bits each for major and minor) is a real ++limitation, and must be fixed somehow. Systems with large numbers of ++SCSI devices, for example, will continue to consume the remaining ++unallocated major numbers. USB will also need to push beyond the 8 bit ++minor limitation ++ ++ ++simply increasing the device number size is insufficient. Apart ++from causing a lot of pain, it doesn't solve the management issues ++of a /dev with thousands or more device nodes ++ ++ ++ignoring the problem of a huge /dev will not make it go ++away, and dismisses the legitimacy of a large number of people who ++want a dynamic /dev ++ ++ ++the standard response then becomes: "write a device management ++daemon", which brings us back to the ++proposal above ++ ++ ++ ++ ++What I don't like about devfs ++ ++Here are some common complaints about devfs, and some suggestions and ++solutions that may make it more palatable for you. I can't please ++everybody, but I do try :-) ++ ++I hate the naming scheme ++ ++First, remember that no naming scheme will please everybody. You hate ++the scheme, others love it. Who's to say who's right and who's wrong? ++Ultimately, the person who writes the code gets to choose, and what ++exists now is a combination of the choices made by the ++devfs author and the ++kernel maintainer (Linus). ++ ++However, not all is lost. If you want to create your own naming ++scheme, it is a simple matter to write a standalone script, hack ++devfsd, or write a script called by devfsd. You can create whatever ++naming scheme you like. ++ ++Further, if you want to remove all traces of the devfs naming scheme ++from /dev, you can mount devfs elsewhere (say ++/devfs) and populate /dev with links into ++/devfs. This population can be automated using devfsd if you ++wish. ++ ++You can even use the VFS binding facility to make the links, rather ++than using symbolic links. This way, you don't even have to see the ++"destination" of these symbolic links. ++ ++Devfs puts policy into the kernel ++ ++There's already policy in the kernel. Device numbers are in fact ++policy (why should the kernel dictate what device numbers I use?). ++Face it, some policy has to be in the kernel. The real difference ++between device names as policy and device numbers as policy is that ++no one will use device numbers directly, because device ++numbers are devoid of meaning to humans and are ugly. At least with ++the devfs device names, (even though you can add your own naming ++scheme) some people will use the devfs-supplied names directly. This ++offends some people :-) ++ ++Devfs is bloatware ++ ++This is not even remotely true. As shown above, ++both code and data size are quite modest. ++ ++ ++How to report bugs ++ ++If you have (or think you have) a bug with devfs, please follow the ++steps below: ++ ++ ++ ++make sure you have enabled debugging output when configuring your ++kernel. You will need to set (at least) the following config options: ++ ++CONFIG_DEVFS_DEBUG=y ++CONFIG_DEBUG_KERNEL=y ++CONFIG_DEBUG_SLAB=y ++ ++ ++ ++please make sure you have the latest devfs patches applied. The ++latest kernel version might not have the latest devfs patches applied ++yet (Linus is very busy) ++ ++ ++save a copy of your complete kernel logs (preferably by ++using the dmesg programme) for later inclusion in your bug ++report. You may need to use the -s switch to increase the ++internal buffer size so you can capture all the boot messages. ++Don't edit or trim the dmesg output ++ ++ ++ ++ ++try booting with devfs=dall passed to the kernel boot ++command line (read the documentation on your bootloader on how to do ++this), and save the result to a file. This may be quite verbose, and ++it may overflow the messages buffer, but try to get as much of it as ++you can ++ ++ ++send a copy of your devfsd configuration file(s) ++ ++send the bug report to me first. ++Don't expect that I will see it if you post it to the linux-kernel ++mailing list. Include all the information listed above, plus ++anything else that you think might be relevant. Put the string ++devfs somewhere in the subject line, so my mail filters mark ++it as urgent ++ ++ ++ ++ ++Here is a general guide on how to ask questions in a way that greatly ++improves your chances of getting a reply: ++ ++http://www.tuxedo.org/~esr/faqs/smart-questions.html. If you have ++a bug to report, you should also read ++ ++http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. ++ ++ ++Strange kernel messages ++ ++You may see devfs-related messages in your kernel logs. Below are some ++messages and what they mean (and what you should do about them, if ++anything). ++ ++ ++ ++devfs_register(fred): could not append to parent, err: -17 ++ ++You need to check what the error code means, but usually 17 means ++EEXIST. This means that a driver attempted to create an entry ++fred in a directory, but there already was an entry with that ++name. This is often caused by flawed boot scripts which untar a bunch ++of inodes into /dev, as a way to restore permissions. This ++message is harmless, as the device nodes will still ++provide access to the driver (unless you use the devfs=only ++boot option, which is only for dedicated souls:-). If you want to get ++rid of these annoying messages, upgrade to devfsd-v1.3.20 and use the ++recommended RESTORE directive to restore permissions. ++ ++ ++devfs_mk_dir(bill): using old entry in dir: c1808724 "" ++ ++This is similar to the message above, except that a driver attempted ++to create a directory named bill, and the parent directory ++has an entry with the same name. In this case, to ensure that drivers ++continue to work properly, the old entry is re-used and given to the ++driver. In 2.5 kernels, the driver is given a NULL entry, and thus, ++under rare circumstances, may not create the require device nodes. ++The solution is the same as above. ++ ++ ++ ++ ++ ++Compilation problems with devfsd ++ ++Usually, you can compile devfsd just by typing in ++make in the source directory, followed by a make ++install (as root). Sometimes, you may have problems, particularly ++on broken configurations. ++ ++ ++ ++error messages relating to DEVFSD_NOTIFY_DELETE ++ ++This happened because you have an ancient set of kernel headers ++installed in /usr/include/linux or /usr/src/linux. ++Install kernel 2.4.10 or later. You may need to pass the ++KERNEL_DIR variable to make (if you did not install ++the new kernel sources as /usr/src/linux), or you may copy ++the devfs_fs.h file in the kernel source tree into ++/usr/include/linux. ++ ++ ++ ++ ++----------------------------------------------------------------------------- ++ ++ ++Other resources ++ ++ ++ ++Douglas Gilbert has written a useful document at ++ ++http://www.torque.net/sg/devfs_scsi.html which ++explores the SCSI subsystem and how it interacts with devfs ++ ++ ++Douglas Gilbert has written another useful document at ++ ++http://www.torque.net/scsi/SCSI-2.4-HOWTO/ which ++discusses the Linux SCSI subsystem in 2.4. ++ ++ ++Johannes Erdfelt has started a discussion paper on Linux and ++hot-swap devices, describing what the requirements are for a scalable ++solution and how and why he's used devfs+devfsd.
