than in dependencies of it, since .BEGIN is apparently only special for
its commands, not its dependencies. This should get boot26, and probably
boot32, compiling again.
and redefine __fpr_regs as an array of 32 ints (SH3E has 16, SH4 has
32 32-bit FP registers) to reserve the space for FPU registers - we
will properly redefine this as a union when we do support FPU.
different meanings for read and write.
This fixes 48kHz playback to SPDIF.
- Fix the problem where the SPDIF output voltage setting (0.5V, 5V)
was swapped. The default value is changed from 0.5V to 5V, which
correctly selects 5V (so the default physical behavior is unchanged).
Should fix PRs kern/16047 and kern/16817
(but not tested since I don't have other SPDIF hardware to test with).

"inpcb", and this struct inpcb* and struct inp6cb* are the same type.
On NetBSD they are different types, so we must change the types of
formal argument in IPv6-specific functions from "struct inpcb *" to
"struct in6pcb*".
The code didn't compile on NetBSD beforehand, if both FAST_IPSEC + INET6
were configured. This fix will cause even more short-term breakage for
that case, but its a step in the right direction: it shows up what
still needs to be fixed.
* Include "opt_inet.h" everywhere IP-ids are generated with ip_newid(),
so the RANDOM_IP_ID option is visible. Also in ip_id(), to ensure
the prototype for ip_randomid() is made visible.
* Add new sysctl to enable randomized IP-ids, provided the kernel was
configured with RANDOM_IP_ID. (The sysctl defaults to zero, and is
a read-only zero if RANDOM_IP_ID is not configured).
Note that the implementation of randomized IP ids is still defective,
and should not be enabled at all (even if configured) without
very careful deliberation. Caveat emptor.
for using /dev/crypto for OpenSSL:
1. Add comments explaining crypto_devallowsoft, explaining the
OpenBSD-style three-way logic actully implemented in crypto_newsession().
2. Pass crypto_devallowsoft as the final argument to crypto_newsession(),
instead of a constant 0 value.
3. Set the default value of crypto_devallowsoft to 1, to allow
/dev/crypto access only for hardware-supported transforms.
Items 1-3 may be revised to match the FreeBSD two-way logic, if the
consensus is that there's no point to forcing software transforms.
But as a first step, let the description match what the code actually does.
GC unused variables usercrypto, userasmcrypto, cryptodevallowsoft from
cryptodev.c, in favour of variables crypto_usercrypto, crypto_userasmcrypto,
crypto_devallowsoft, which are used as well as defined in crypto.c.

Avoids corruption of anything pointed to by r3 and r4 on entry to
os_get_env, and allows pass-by-reference values to be returned.
blocked in the kernel. The task that catched the exception may unblock
it by sending a reply to the exception message (Of course it will have
to change something so that the exception is not immediatly raised again).
Handling of this reply is a bit complicated, as the kernel acts as the
client instead of the server. In this situation, we receive a message
but we will not send any reply (the message we receive is already a reply).
I have not found anything better than a special case in
mach_msg_overwrite_trap() to handle this.
A surprise: exceptions ports are preserved accross forks.
While we are there, use appropriate 64 bit types for make_memory_entry_64.
- always wait for unblocked upcall if we have to continue a blocked
thread.
=> removes wakeup from sys_sa_stacks when a stack is returned.
=> avoids extra sa_unblockyield syscall when unblocked upcall is
delivered before blocked upcall is processed.
=> avoids double pagefault if we continued a thread before the
pagefault was resolved.
=> avoids losing unblocked state if we continued a thread after
skipping the unblocked upcall.
- use splay tree for the pagefault check if the thread was running on
an upcall stack.
=> removes the limitation that all upcall stacks need to be
adjoining and that all upcall stacks have to be loaded with the
1st sys_sa_stacks call.
=> enables keeping information associated with a stack in the kernel
which makes it simpler to find out which LWP is using a stack.
=> allows increasing the SA_MAXNUMSTACKS without having to
allocate an array of that size.
Revert the (default) ip_id algorithm to the pre-randomid algorithm,
due to demonstrated low-period repeated IDs from the randomized IP_id
code. Consensus is that the low-period repetition (much less than
2^15) is not suitable for general-purpose use.
Allocators of new IPv4 IDs should now call the function ip_newid().
Randomized IP_ids is now a config-time option, "options RANDOM_IP_ID".
ip_newid() can use ip_random-id()_IP_ID if and only if configured
with RANDOM_IP_ID. A sysctl knob should be provided.
This API may be reworked in the near future to support linear ip_id
counters per (src,dst) IP-address pair.

symbols, and made it impossible for the kernel to use that value, and

o Allow LKM users to use DDB to debug the entry function of a LKM by
loading the symbol table with the temporary name /lkmtemp/ before calling
it, and then renaming it once we know the module name.

may turn into exceptions on Mach: a small message sent by the kernel to
the task that requested the exception.
On Darwin, when an exception is sent, no signal can be delivered.
TODO: more exceptions: arithmetic, bad instructions, emulation, s
software, and syscalls (plain and Mach). There is also RPC alert, but
I have no idea about what it is.
While we are there, remove some user ktrace in notification code, and add
a NODEF qualifier in mach_services.master: it will be used for notifications
and exceptions, where the kernel is always client and never server: we
don't want the message to be displayed as "unimplemented xxx" in kdump (thus
UNIMPL is not good), but we don't want to generate the server prototype
(therefore, STD is not good either). NODEF will declare it normally in the
name tables without creating the prototype.
local-loopback (lo0). As posted for review on tech-kern 2003-18-09,
with a long comment explaining (one of) the deadlock scenarios.
I've used this since shortly after 2002-09-12-, without noticing
performance degradataion or instability for non-loopback mounts.
- tweak some attach messages
- establish interrupt after all dma resouces are successfully allocated
- wrap an assertion with #ifdef DIAGNOSTIC
- assume NCRCFG2_FE bit is always enabled
- call bus_dmamap_sync for mdldmap at POSTWRITE for consistency
- pass proper dmamapsize for mdldmap
crossing boundary in iommu_dvmamap_load().
Fixes E2BIG error on dmamap with smaller boundary size than maxxfersize
(which is used by recent changed pcscp(4)).
While here, some KNF around debug printf etc.
the functionality of ixp425_bs_tag.
- Add missing stream_{read,write}_1 ops to ixp425_bs_tag.
- Re-work the delay() implementation to use the free-running Time-
Stamp counter. This removes the need to bootstrap TMR0 early on.
bswapl, and bf_cbc.S uses it. Unfortunately, this means that GENERIC
will no longer use the asm code -- though it will still use the asm
for the basic Blowfish transform. This won't slow down the KAME IPsec
(since it rolls its own CBC) but may slow down fast-ipsec in kernels
that have I386_CPU defined.
Not tested on 795[56], but compiles and matches FreeBSD-tested diffs.

will have unimplemented services showing their names in ktrace
Add a new generated file with only service id and name, which will
be included by kdump to display services names.
This removes the need for using the user ktrace facility for services names.
- factor out disksubr.c between sun3, sparc and sparc64. Keep the sun3
groveling code to find a NetBSD disklabel in the first sector (so that it
can find a label at the old sun3 LABELOFFSET) as a fallback is not
label at LABELOFFSET, or sun label is present.
- Fix the sun3 LABELOFFSET (was 64, but the kernel wrote the NetBSD label at
128)
- Make next68k disksubr.c always write a next-compatible disklabel.
- remove #ifdef __sparc__ hack from disklabel(8), and change it to issue
a DIOCWDINFO after writing the disklabel to the raw partition in the
-r/-I case (so that the kernel can convert the label if needed).
