- Remove reference to the obsolete options: BOOT_PROBE_KEYBOARD,
BOOT_PROBE_KEYBOARD_LOCK and BOOT_FORCE_COMCONSOLE.
- Add reference to BOOT_COMCONSOLE_SPEED.
If you want to play with it, you can find the final version of the
code in the repository the tag LFS_RETIREMENT.
If somebody makes LFS work again, adding it back is certainly
desireable, but as it is now nobody seems to care much about it,
and it has suffered considerable bitrot since its somewhat haphazard
integration.
R.I.P
available. If there isn't bounce space available, the bounce code
is disabled. This will allow most large systems to run properly
when the bounce space is mistakenly allocated above 16MB.
Don't mention the authors name at startup. He's already credited
in the man page. Instead, make the message consistent with the
one given to the diagnostic port (and fix the grammar when entering
`term' mode).
Don't credit the zlib author in the man page as ppp isn't linked
directly with zlib (it's shared).
Mention when the OpenBSD port was first made available.
All known versions of this drive (firmware 21.* and 23.*) will lock up
if presented with a read/write request of > 64 blocks. In the presence
of such a unit, I/O requests of > 64 blocks are fragmented to avoid
this.
- define CTL-ALT-ESC as `debug' key in all keymaps. (FAQ mentions this
key sequence but not all keymaps had it!)
- define CTL-SPACE as NUL in all keymaps.
- define CTL-ALT-SPACE as `suspend' key in all but Russiun keymaps.
- Fix Japanese keymaps. Some CTL- keystrokes were wrong.
- Remove accent (dead) key definitions from spanish.iso.kbd,
fr.iso.kbd and icelandic.iso.kbd. Create spanish.iso.acc.kbd,
fr.iso.acc.kbd and icelandic.iso.acc.kbd with accent key definitions
instead.
- Update INDEX.keymaps and Makefile.
a hashed port list. In the new scheme, in_pcblookup() goes away and is
replaced by a new routine, in_pcblookup_local() for doing the local port
check. Note that this implementation is space inefficient in that the PCB
struct is now too large to fit into 128 bytes. I might deal with this in the
future by using the new zone allocator, but I wanted these changes to be
extensively tested in their current form first.
Also:
1) Fixed off-by-one errors in the port lookup loops in in_pcbbind().
2) Got rid of some unneeded rehashing. Adding a new routine, in_pcbinshash()
to do the initialial hash insertion.
3) Renamed in_pcblookuphash() to in_pcblookup_hash() for easier readability.
4) Added a new routine, in_pcbremlists() to remove the PCB from the various
hash lists.
5) Added/deleted comments where appropriate.
6) Removed unnecessary splnet() locking. In general, the PCB functions should
be called at splnet()...there are unfortunately a few exceptions, however.
7) Reorganized a few structs for better cache line behavior.
8) Killed my TCP_ACK_HACK kludge. It may come back in a different form in
the future, however.
These changes have been tested on wcarchive for more than a month. In tests
done here, connection establishment overhead is reduced by more than 50
times, thus getting rid of one of the major networking scalability problems.
Still to do: make tcp_fastimo/tcp_slowtimo scale well for systems with a
large number of connections. tcp_fastimo is easy; tcp_slowtimo is difficult.
WARNING: Anything that knows about inpcb and tcpcb structs will have to be
recompiled; at the very least, this includes netstat(1).
