- don't reboot() when feed with wrong parameters (and enough permissions) [1] - add support to power off the system [2] - check the linux magic values [3] Submitted by: Marcin Cieslak [1,2] Modelled after: linux man page of the reboot() syscall [3] Found by: LTP testcase "reboot02" [1] Tested with: LTP testcase "reboot02" [1,3] Approved by: re (hrs)

- linux_misc.c 1.179 Don't copyout/do unneccesary work if the buffer is a NULL pointer. Noticed by: Dmitry Ganenko Reviewed by: rdivacky (the original version as in emulation@) - linprocfs.c 1.96: Improve linprovfs to provide/fix the - process state (idle, sleeping, running, ...) [1] - the process group ID of the process which owns the connected tty - some page fault stats - time spend in kernel/userland - priority/nice value - starttime [1] - memory/swap stats - scheduling policy Additionally add some new fields and correct some not filled out ones. This brings us down to 15 dummy fields. The fields marked with [1] are needed to get Oracle 10 running. The starttime field is not completely right, since it displays the _same_ starttime for _every_ process, but at least it is not 0 and Oracle accepts this. Noticed by: Dmitry Ganenko [1] Reviewed by: des, rdivacky - pseudofs_vnops.c 1.60: Correctly calculate a buffer length. It was off by one so a read() returned one byte less than needed. Noticed by: Dmitry Ganenko Testcase by: Dmitry Ganenko Reviewed by: des Submitted by: rdivacky Sponsored by: Google SoC 2006 All of those are needed for Oracle 10. Since previous Oracle versions work just fine without those fixes, these patches can be seen as regression fixes too. Because of this I think they are a RELENG_6_x candidate (MFC reminder set).

Fix the computation of uptime for linux_sysinfo(). Before it was returning

- Pass the ISOPEN flag to namei so filesystems will know we're about to

2005-04-27T09:05:19Z

open them or otherwise access the data.

- Change the vm_mmap() function to accept an objtype_t parameter specifying

2005-04-01T20:00:11Z

the type of object represented by the handle argument. - Allow vm_mmap() to map device memory via cdev objects in addition to vnodes and anonymous memory. Note that mmaping a cdev directly does not currently perform any MAC checks like mapping a vnode does. - Unbreak the DRM getbufs ioctl by having it call vm_mmap() directly on the cdev the ioctl is acting on rather than trying to find a suitable vnode to map from.

Handle unimplemented syscall by instantly returning ENOSYS instead of sending

2005-03-07T00:18:06Z

signal first and only then returning ENOSYS to match what real linux does. PR: kern/74302 Submitted by: Travis Poppe

Use kern_setitimer() to implement linux_alarm() instead of fondling the

real interval timer directly.

Split out kernel side of {get,set}itimer(2) into two parts: the first that

pops data from the userland and pushes results back and the second which does actual processing. Use the latter to eliminate stackgap in the linux wrappers of those syscalls. MFC after: 2 weeks
