* - Minimize the amount of duplicated code for the PREEMPTION #ifdef, it nowjhb2001-02-051-27/+9
| | | | | | | | | | | | only covers about 3-4 lines. - Don't lower the IPL while we are on the interrupt stack. Instead, save the raised IPL and change the saved IPL in sched_lock to IPL_0 before calling mi_switch(). When we are resumed, restore the saved IPL in sched_lock to the saved raised IPL so that when we release sched_lock we won't lower the IPL. Without this, we would get nested interrupts that would overflow the kernel stack. Tested by: mjacob

* This commit represents work mainly submitted by Tor and slightly modifieddillon2001-02-044-13/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | by myself. It solves a serious vm_map corruption problem that can occur with the buffer cache when block sizes > 64K are used. This code has been heavily tested in -stable but only tested somewhat on -current. An MFC will occur in a few days. My additions include the vm_map_simplify_entry() and minor buffer cache boundry case fix. Make the buffer cache use a system map for buffer cache KVM rather then a normal map. Ensure that VM objects are not allocated for system maps. There were cases where a buffer map could wind up with a backing VM object -- normally harmless, but this could also result in the buffer cache blocking in places where it assumes no blocking will occur, possibly resulting in corrupted maps. Fix a minor boundry case in the buffer cache size limit is reached that could result in non-optimal code. Add vm_map_simplify_entry() calls to prevent 'creeping proliferation' of vm_map_entry's in the buffer cache's vm_map. Previously only a simple linear optimization was made. (The buffer vm_map typically has only a handful of vm_map_entry's. This stabilizes it at that level permanently). PR: 20609 Submitted by: (Tor Egge) tegge

* Extend the sanity checks in ufs_lookup to ensure that each directoryiedowse2001-02-041-1/+2
| | | | | | | | | | | | | | entry fits within its DIRBLKSIZ block. The surrounding code is extremely fragile with respect to corruption of the directory entry 'd_reclen' field; if directory corruption occurs, it can blindly scan forward beyond the end of the filesystem block. Usually this results in a 'fault on nofault entry' panic. Directory corruption is now much more likely to be detected, resulting in a 'ufs_dirbad' panic. If the filesystem is read-only, it will simply print a warning message, and skip the corrupted block. Reviewed by: mckusick

| | | | | | | | | | in ufs_dirbad(). The mnt_stat.f_flags field is only updated by the syscalls *statfs and getfsstat, so mnt_flag should be used instead. This only affects whether or not a panic is generated on detection of certain types of directory corruption. Reviewed by: mckusick

A new flag in the trapframe indicates that the frame only holds partial state. When it is necessary to perform a full state restore (e.g. after an execve or signal), the flag is cleared to force a full restore.
