Reject negative ngrp arguments in linux_setgroups() and linux_setgroups16();

stops users being able to cause setgroups to clobber the kernel stack by copying in data past the end of the linux_gidset array.

Restored a non-egregious cast so that this file compiles on i386's

with 64-bit longs again. This was fixed in rev.1.42 but the fix rotted non-fatally in rev.1.105 and fatally in rev.1.137. Many more non-egregrious casts are strictly required for conversions from semi-opaque types to pointers, but we avoid most of them by using types that are almost certain to be compatible with uintptr_t for representing pointers (e.g., vm_offset_t). Here we don't really want the u_longs, but we have them because a.out.h and its support code doesn't use typedefs (it uses unsigned in V7 and unsigned long in FreeBSD) and is too obsolete to fix now.

Try to make 'uname -a' look more like it does on Linux:

- cut the version string at the newline, suppressing information about who built the kernel and in what directory. Most of this information was already lost to truncation. - on i386, return the precise CPU class (if known) rather than just "i386". Linux software which uses this information to select which binary to run often does not know what to make of "i386".

Add a "int fd" argument to VOP_OPEN() which in the future will

2003-07-26T07:32:23Z

contain the filedescriptor number on opens from userland. The index is used rather than a "struct file *" since it conveys a bit more information, which may be useful to in particular fdescfs and /dev/fd/* For now pass -1 all over the place.

Add a new function swap_pager_status() which reports the total size of the

2003-07-18T10:26:09Z

paging space and how much of it is in use (in pages). Use this interface from the Linuxolator instead of groping around in the internals of the swap_pager.

Use __FBSDID().
