| | | | | | | | | | | their own directory and module, leaving the MD parts in the MD area (the MD parts _are_ part of the modules). /dev/mem and /dev/io are now loadable modules, thus taking us one step further towards a kernel created entirely out of modules.

It is a pretty hard to come up with even a theoretical concept of a device driver which would always fail open and close with ENODEV. Change the defaults to be nullopen() and nullclose() which simply does nothing. Remove explicit initializations to these from the drivers which already used them.

* Change the suser() API to take advantage of td_ucred as well as do aJohn Baldwin2002-04-011-1/+1
| | | | | | | | | | | | | | | general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.

* Here follows the new kernel dumping infrastructure.Poul-Henning Kamp2002-03-311-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Caveats: The new savecore program is not complete in the sense that it emulates enough of the old savecores features to do the job, but implements none of the options yet. I would appreciate if a userland hacker could help me out getting savecore to do what we want it to do from a users point of view, compression, email-notification, space reservation etc etc. (send me email if you are interested). Currently, savecore will scan all devices marked as "swap" or "dump" in /etc/fstab _or_ any devices specified on the command-line. All architectures but i386 lack an implementation of dumpsys(), but looking at the i386 version it should be trivial for anybody familiar with the platform(s) to provide this function. Documentation is quite sparse at this time, more to come. Details: ATA and SCSI drivers should work as the dump formatting code has been removed. The IDA, TWE and AAC have not yet been converted. Dumpon now opens the device and uses ioctl(DIOCGKERNELDUMP) to set the device as dumpdev. To implement the "off" argument, /dev/null is used as the device. Savecore will fail if handed any options since they are not (yet) implemented. All devices marked "dump" or "swap" in /etc/fstab will be scanned and dumps found will be saved to diskfiles named from the MD5 hash of the header record. The header record is dumped in readable format in the .info file. The kernel is not saved. Only complete dumps will be saved. All maintainer rights for this code are disclaimed: feel free to improve and extend. Sponsored by: DARPA, NAI Labs Notes: svn path=/head/; revision=93496

* New machine independant /dev/null and /dev/zero driver. This device isMark Murray2000-06-251-0/+137
severely stripped down compared with its predecessor, and is measurably a _lot_ faster. Many thanks to Jeroen van Gelderen for lots of good ideas. There is still a problem with this; it is written as a mudule, and as such is theoretically unloadable. However, there is no refcounting done as I would prefer to do that a'la device_busy(9), rather than some "home-rolled" scheme. The point is pretty moot, as /dev/null is effectively compulsory.
