16be165733 Don't allow ISO images to be made that try to use boot.flp to boot as the
boot.flp in 5.3 and later is not self-contained and thus not suitable for
CD booting.  /boot/cdboot is now the only way to boot the install CDs.

should not return ERESTART after it caught a signal, otherwise
thr_wake() call will be lost, also a timeout wait should not be

a138ae34c4 The following code sets up two connected TCP sockets that send data to each
other until the window is closed. Then one of the sockets is closed, which
will generate a RST once the TCP at the other socket does a window probe.

All versions of FreeBSD prior to 11/26/2004 will ignore this RST into a 0
window, causing the connection (and application) to hang indefinitely.
On patched versions of FreeBSD (and other operating systems), the RST
will be accepted and the program will exit in a few seconds.

4392c73e67 Fix a bunch of stack leaks. These were theoretically harmless, except that
they would leave enough elements on the stack that if you escaped to the
loader prompt and then typed 'setenv', it would pull in all of the leaked
junk and cause an exception in the environment.  There still seems to be
3 leaked elements, but they don't appear to be coming from this file.

3601987765 Fix for a race between lookup and readdirplus, that causes
a deadlock (with NFS exclusive vnode locks enabled). Lookup
grabs the parent's lock and wants to lock child. Readdirplus
locks the child and wants to lock parent (for loading the attrs
for ".."). The fix is to not load the attrs for ".." in
readdirplus.

c106bd9120 Change gdb_cpu_setreg() to not take the value to which to set the
specified register, but a pointer to the in-memory representation of
that value. The reason for this is twofold:
1. Not all registers can be represented by a register_t. In particular
   FP registers fall in that category. Passing the new register value
   by reference instead of by value makes this point moot.
2. When we receive a G or P packet, both are for writing a register,
   the packet will have the register value in target-byte order and
   in the memory representation (modulo the fact that bytes are sent
   as 2 printable hexadecimal numbers of course). We only need to
   decode the packet to have a pointer to the register value.

This change fixes the bug of extracting the register value of the P
packet as a hexadecimal number instead of as a bit array. The quick
(and dirty) fix to bswap the register value in gdb_cpu_setreg() as
it has been added on i386 and amd64 can therefore be removed and has
in fact been that.

Tested on: alpha, amd64, i386, ia64, sparc64

834b0b8b46 Implement the check I was talking about in the previous message already.
Introduce domain_init_status to keep track of the init status of the domains
list (surprise). 0 = uninitialized, 1 = initialized/unpopulated, 2 =
initialized/done. Higher values can be used to support late addition of
domains which right now "works", but is potential dangerous. I choose to
only give a warning when doing so.

Use domain_init_status with if_attachdomain[1]() to ensure that we have a
complete domains list when we init the if_afdata array. Store the current
value of domain_init_status in if_afdata_initialized. This way we can update
if_afdata after a new protocol has been added (once that is allowed).

ea0fd1c083 Move ng_socket and ng_btsocket initialization to SI_SUB_PROTO_DOMAIN as they
call net_add_domain(). Calling this function too early (or late) breaks
assertations about the global domains list.
Actually it should be forbidden to call net_add_domain() outside of
SI_SUB_PROTO_DOMAIN completely as there are many places where we traverse
the domains list unprotected, but for now we allow late calls (mostly to
support netgraph). In order to really fix this we have to lock the domains
list in all places or find another way to ensure that we can safely walk the
list while another thread might be adding a new domain.

ecb168af50 1. use per-chain mutex instead of global mutex to reduce
lock collision.
2. Fix two race conditions. One is between _umtx_unlock and signal,
   also a thread was marked TDF_UMTXWAKEUP by _umtx_unlock, it is
   possible a signal delivered to the thread will cause msleep
   returns EINTR, and the thread breaks out of loop, this causes
   umtx ownership is not transfered to the thread. Another is in
   _umtx_unlock itself, when the function sets the umtx to
   UMTX_UNOWNED state, a new thread can come in and lock the umtx,
   also the function tries to set contested bit flag, but it will
   fail. Although the function will wake a blocked thread, if that
   thread breaks out of loop by signal, no contested bit will be set.

4671aabad6 Add observations of the Linux98 and Grub/98 boot loaders. These
observations lead me to believe that the convetion for pc98 boot
loaders is to have a jump unstruction, followed by a string, followed
by code.  The jump usually doesn't have a nop after it and usually the
string is NUL terminated, but Grub/98 breaks both of these rules.

b06b583ff5 Reject tasting of this provider if the sector size isn't a multiple of
512.  If I had an audio cdrom in my cd player when I booted my system,
I'd get a panic from geom because you can't read 8192 bytes from an
audio cdrom.

Remove XXX comment about IPL1 and replace it with some information
from my soon to be published web page on the pc98 disk layout.  The
IPL1 test was the result of an observation of a disk with FreeBSD's
boot0 program.  It was testing part of an area what appears to be
reserved for a boot loader name, which comes after a jump over this
area.  I don't yet know if it is required to be any specific jump
instruction, or if the destination has to be location 11. [1]

[1] FreeBSD Press No. 13, page 115, poorly translated by myself.  The
picture there shows offset 8 as the destination of the jump, but
FreeBSD's boot0 program has three padding NULs after the IPL1 name and
uses a 16-bit 'jmp' instruction.

504bb0d4c8 Make sure the link array is big enough to hold both _CRS and _PRS
resource lists.  It used to be sized based only on _CRS, hence _PRS could
perform an out-of-bounds access if it was larger (i.e., when there are
dependent functions).  Add asserts to detect this case.  Note, this is
only a temporary fix and I believe _PRS and _CRS should have separate
arrays.

Also, fix a typo where the wrong irq was being check for the APIC case.
