Change default key allocation method to do the right thing for
legacy parts (i.e. those that have 4 global key slots). We
blindly assign unicast keys to key slot 0. Devices that need
alternate allocation logic must override this method.
sys/sys/pmc.h, sys/dev/hwpmc/hwpmc_mod.c:
- Fix a bug affecting debug printfs.
- Move the 'stalled' flag from being in a bit in the
'pm_flags' field of a 'struct pmc' to a field of its own in the
same structure. This flag is updated from the NMI handler and
keeping it separate makes it easier to avoid races with other
parts of the code.
sys/dev/hwpmc/hwpmc_logging.c:
- Do arithmetic with 'uintptr_t' types rather that casting
to and from 'char *'.
Have the NMI handler call the C language trap() routine and directly
exit via 'doreti_exit'.
Since the NMI interrupt may be taken at any time, including when
the processor has masked external interrupts, it is not safe to
call ast() as is done for normal interrupts.
Some cleanups and tweaks to some of the atomic.h files in preparation for
further changes and fixes in the future:
- Use aliases via macros rather than duplicated inlines wherever possible.
- Move all the aliases to the bottom of these files and the inline
functions to the top.
- Add various comments.
- On alpha, drop atomic_{load_acq,store_rel}_{8,char,16,short}().
- On i386 and amd64, don't duplicate the extern declarations for functions
in the two non-inline cases (KLD_MODULE and compiler doesn't do inlines),
instead, consolidate those two cases.
- Some whitespace fixes.
Add missing locking to linux_connect() so that it can be marked MP safe:
- Conditionally grab Giant around the EISCONN hack at the end based on
debug.mpsafenet.
- Protect access to so_emuldata via SOCK_LOCK.
The nsegs parameter to bus_dmamap_load_mbuf_sg is not required to
be set to 0 on input. This caused a panic in an an MP test version
of the GEM driver from Marius, and from inspection of other PCI
drivers, the same problem would happen there.
Fix by explicitly setting to 0.
Add Farrallon EtherMac PC Card to the list of supported cards.
Fix XJack card description to reflect the actual model that we support
(I've never seen a CC-10BT and I've been looking).
List the specific chipsets supported.
Bump date.
Approved by: re (scottl, indirectly due to driver approval)
Noticed that NetBSD's sm driver has the PSION GOLDCARD listed, so list
that since I can't test it directly. The driver also lists the EM1144
as being supported, but in reality it isn't. The EM1144-T,
{XJ,CC}{3288,3336} have the SMC chips in them, but aren't conformant MFC
cards, so they need their own driver.
Also, it does little harm to list the 8020BT, so remove #if 0.
Change communication protocol to be much more resistant on network
problems and to allow for much better performance.
Better performance is achieved by creating two connections between
ggatec and ggated one for sending the data and one for receiving it.
Every connection is handled by separeted thread, so there is no more
synchronous data flow (send and wait for response), now one threads
sends all requests and another receives the data.
Use two threads in ggatec(8):
- sendtd, which takes I/O requests from the kernel and sends them to the
ggated daemon on the other end;
- recvtd, which waits for ggated responses and forwards them to the kernel.
Use three threads in ggated(8):
- recvtd, which waits for I/O requests and puts them onto incoming queue;
- disktd, which takes requests from the incoming queue, does disk operations
and puts finished requests onto outgoing queue;
- sendtd, which takes finished requests from the outgoing queue and sends
responses back to ggatec.
Because there were major changes in communication protocol, there is no
backward compatibility, from now on, both client and server has to run
on 5.x or 6.x (or at least ggated should be from the same FreeBSD version
on which ggatec is running).
For Gbit networks some buffers need to be increased. I use those settings:
kern.ipc.maxsockbuf=16777216
net.inet.tcp.sendspace=8388608
net.inet.tcp.recvspace=8388608
and I use '-S 4194304 -R 4194304' options for both, ggatec and ggated.
ral_init() takes a struct ral_softc as parameter not a struct ifnet.
Fixes a panic that occured when setting the interface parameters while
the interface was associated.
Use implicit type cast for ->k_lock to fix compilation of ndis
as a part of the GENERIC kernel with INVARIANT* and WITNESS*
turned off.
(For non GENERIC kernel KTR and MUTEX_PROFILING should be also
off).

(Note this makes the vendor branch not represent Binutils in the vendor's

Binutils on Sparc that represented the point in time the vendor fixed this
issue. I'd rather have fixed this on RELENG_6.)

Conditionally acquire Giant around the ISC and Xenix system calls based

Lock Giant in svr4_add_socket() so that the various svr4_*stat() calls
can be marked MP safe as this is the only part of them that is not
already MP safe.
Rototill this file so that it actually compiles. It doesn't do anything
in the build still due to some #undef's in svr4.h, but if you hack around
that and add some missing entries to syscalls.master, then this file will
now compile. The changes involved proc -> thread, using FreeBSD syscall
names instead of NetBSD, and axeing syscallarg() and retval arguments.
- Remove spl's from osf1_usleep_thread().
- Fix the calculation of the 'slept' timeval returned by
osf1_usleep_thread() which has been broken since 1.1.
- Add two new system calls: preadv() and pwritev() which are like readv()
and writev() except that they take an additional offset argument and do
not change the current file position. In SAT speak:
preadv:readv::pread:read and pwritev:writev::pwrite:write.
- Try to reduce code duplication some by merging most of the old
kern_foov() and dofilefoo() functions into new dofilefoo() functions
that are called by kern_foov() and kern_pfoov(). The non-v functions
now all generate a simple uio on the stack from the passed in arguments
and then call kern_foov(). For example, read() now just builds a uio and
calls kern_readv() and pwrite() just builds a uio and calls kern_pwritev().

This is sort of an MFS. Peter made these changes to the RELENG_*
branches but missed HEAD. This patch extends his a little bit,
setting it up via the Makefiles so that adding _FREEFALL_CONFIG
to /etc/make.conf is the only thing needed to cluster-ize things
(current setup also requires overriding CFLAGS).
From Peter's commit to the RELENG_* branches:

> * don't fall back to asking for a unix password (ie: be pure kerberos)

- Previously when broadcasting to N number of interfaces we would run pfil
hooks for each outgoing interface but also run pfil hooks _N times_ on the
bridge interface. This is changed so pfil hooks are run once for the bridge
interface (bridge0) and then only on the outgoing interfaces in the broadcast
loop.
- Simplify bridge_enqueue() by moving bridge_pfil() to the callers.
- Check (inet6_pfil_hook.ph_busy_count >= 0), it may be possible to have a
packet filter hooked for only ipv6 but we were only checking if ipv4 hooks
were busy.
- Minor optimisation for null mbuf check after bridge_pfil(), move it into the
if-block as it couldnt possibly be null outside.

In the splnet times, netgraph was functional and synchronous. Nowadays,
an item may be queued and processed later. While this is OK for mbufs,
this is a problem for control messages.
In the framework:
- Add optional callback function pointer to an item. When item gets
applied the callback is executed from ng_apply_item().
- Add new flag NG_PROGRESS. If this flag is supplied, then return
EINPROGRESS instead of 0 in case if item failed to deliver
synchronously and was queued.
- Honor NG_PROGRESS in ng_snd_item().
In ng_socket:
- When userland sends control message add callback to the item.
- If ng_snd_item() returns EINPROGRESS, then sleep.
This change fixes possible races in ngctl(8) scripts.
Enhance ia64_flush_dirty() to handle the case in which td != curthread.
