d22ddeb9cf Correct vendor code for Kingston DT101 G2 2011-09-03 16:19:47 +00:00

a8da4706c3 Add SIGILL handler, doing nothing than printing out details. 
Move the address check to be done later so pmap and uvm have their go first.

Also some minor cosmetic fixes

24f1db749c Instead of doing #include </usr/include/machine/..>, use the headers 
that ship with the kernel sources as #include "../../$host/include/$hdr",
and auto-generate these ugly headers with a script.

a315582ad2 We need to process SA_STOP signals immediately, and not deliver them to 
the process. Instead of re-structuring the code to do that, call issignal()
like before in that case. (tail -F /file^Zfg should not get interrupted).

78b0e18345 Report vmem(9) errors out-of-band so that we can use vmem(9) to manage 
ranges that include the least and the greatest vmem_addr_t.  Update
vmem(9) uses throughout the kernel.  Slightly expand on the tests in
subr_vmem.c, which still pass.  I've been running a kernel with this
patch without any trouble.

72a34c792c Add support for PTRACE_FORK. 
- add a field in struct proc to save the forker/forkee pid, and a flag.
- add 3 new ptrace calls: PT_GET_PROCESS_STATE, PT_GET_EVENT_MASK,
  PT_SET_EVENT_MASK
Add a PT_STRINGS constant so that we don't hard-code the list of ptrace
subcalls in other programs (kdump).

b4ab627dec Add support for PTRACE_FORK. NB: This does not (yet) work for vfork(), because: 
1. When we vfork() PL_PPWAIT is set, and that makes us do regular disposition
   of the TRAP signal, and not indirect through the debugger.
2. The parent needs to keep running, so that the debugger can release it.
   Unfortunately, with vfork() we cannot release the parent because it will
   eventually core-dump since the parent and the child cannot run on the
   same address space.

bac4b71fcb If the process is traced, resulting from a PTRACE_FORK inherited setting, 
stop it right now.

XXX[1]: Cannot make this MI, because I cannot wrap child_return because there
is MD code that checks fun == child_return. I think it is better to have an
mi child_return() and add a cpu_child_return()?
XXX[2]: Why do we need to stop so early? Perhaps stopping just after exec
is better?

dfe7b794ce Always make sure that kte_entry is aligned appropriately so register_t can 
be stored there.  (not really a problem right now since time_t is now 64bit
bit and it just works but it's better to be explicit).

0e730cfa32 Use a alternative dedicated signal stack for the sigsegv errors; the userland

acf0c89366 redo vfs_lookup.c rev.1.126. 
when crossing a mount point, don't keep the parent vnode locked.
ie. don't lock a vnode while holding another vnode which belongs to a
different filesystem.  otherwise we propagate slowness (or deadness) of a
filesystem to another via vnode lock chain.

fc8de2b005 Enhance debugging capabilities of NetBSD/usermode by allowing `trap.c' to 
write a system image of the memory it traps. Its extremely dirty but at least
you can look at the data and code thats giving the trouble. Its memory or
state is NOT saved in the coredump of the NetBSD/usermode program.

c41a9ea5e1 It seems mvsata_bio_ready() is actually needed, and it seems 
to work better if we always poll for completion for the
duration of this function.

883c2687f6 We occasionally will try to set up the multicast filter in a context that 
kmem(9) is unusable (such as transmit timeout). Thus, put the filter table
on the stack instead, all 528 bytes of it.
