Implement SCB paging. This allows up to 255 active commands on
aic7770 >= Rev E, aic7850, aic7860, aic7870, and ai7880 based controllers.
Make findSCB safer for non-tagged commands when tagged commands are
active on the controller. The symptoms of this problem were
"Overlapped commands attempted" messages during error recovery
attempts.
Compact scratch ram usage. This leaves 8 bytes free for future use.
Implement support for LD_PRELOAD in the dynamic linker. Remove
descriptions of LD_NO_INTERN_SEARCH and LD_NOSTD_PATH from the manual
page, since they are not supported.
Yet more b_flags fixes. The previous ones broke the clearing of B_DONE
and B_READ before writing. This was was fatal. They also broke the
clearing of B_INVAL before doing i/o. This didn't actually matter.
Fixed removal of devfs entries for the real slice corresponding to the
compatibility slice. They were forgotten on last-close and then
creating them on first-open failed.
Devfs entries for slices other than the one containing the root file
system are still invisible unless you open a non-devfs inode on the
slice.
Removed bogus includes of <sys/types.h> from synopses.
This commit covers the man pages for most of the ANSI library functions.
A few others such as strtol.3 have to mention <sys/types.h> because they
mix ANSI interfaces with less well designed extensions.
- Addition of my name to the APM Copyright
- More code cleanups
- #ifdef DEBUG debugging code
- More consistant printfs
- Better handling of the apm_int() assembly code (mostly from Bruce Evans)
Three speed-ups in the output path (two small, one substantial):
1) Require all callers to pass a valid route pointer to ip_output()
so that we don't have to check and allocate one off the stack
as was done before. This eliminates one test and some stack
bloat from the common (UDP and TCP) case.
2) Perform the IP header checksum in-line if it's of the usual length.
This results in about a 5% speed-up in my packet-generation test.
3) Use ip_vhl field rather than ip_v and ip_hl bitfields.
Remove the special-case behavior for fire actions that return
DITEM_FAILURE - formerly they would simply act as an implicit "continue",
but this is wrong. If you want this behavior, you should now return
with the DITEM_CONTINUE flag set.
Also make the semantics of DITEM_RESTORE quite a bit different - rather
than restore the screen back to pre-menu state, we restore the menu
itself. This is more correct for a variety of reasons when dealing with
nested menus (whoops!).

Add in linux support for the quickcam driver bottom half and

More changes to attempt to make this whole new dialog scheme more
robust. The new "fire" actions, while affording signficantly more
interactivity to libdialog, come at a cost - if the fire action trashes
the screen then you're not going to be in Kansas anymore when you
come back to the menu and there had better be considerable extra
smarts in place for coping with such a situation. These changes are my
attempt to do just that.
NIS cleanups and fixes, the next generation, continued.
pwd_mkdb.c:
- Don't save the PLUSCNT and MINUSCNT tokens: we don't need them anymore.
- Count the + and - entires for NIS together instead of counting + and -
entries seperately. Index all special NIS entries using new _PW_KEYYPBYNUM
token.
pwd.h:
- Remove the PLUSBYNUM, MINUSBYNUM, PLUSCNT and MINUSCNT tokens and replace
then with a single _PW_KEYYPBYNUM token.
- Catch one bogon that snuck by: in _listmatch(), check for '\0'
rather than '\n'; strings returned from yp_match() are terminated
with a nul, not a newline.
getpwent.c:
- Rip out all of the +inclusion/-exclusion stuff from before and
replace it with something a little less grotty. The main problem
with the old mechanism was that it wasted many cycles processing
NIS entries even after it already knew they were to be exlcuded
(or not included, depending on your pointof view). The highlights
of these changes include:
o Uses an in-memory hash database table to keep track of all the
-@netgroup, -user, and -@group exclusions.
o Tries harder to duplicate the behavior normally obtained when using
NIS inclusions/exclusions on a flat /etc/passwd file (meaning things
come out in much the same order).
o Uses seperate methods for handling getpwent() and getpwnam()/getpwuid()
operations instead of trying to do everything with one general
function, which didn't work as well as I thought it would.
o Uses both getnetgrent() and innetgr() to try to save time where
possible.
o Use only one special token in the local password database
(_PW_KEYYPBYNUM) instead of seperate tokens to mark + and -
entries (and stop using the counter tokens too). If this new
token doesn't exist, the code will make due with the standard
_PW_KEYBYNUM token in order to support older databases that
won't have the new token in them.
All this is an attempt to make this stuff work better in environments
with large NIS passwd databases.
- Clear the _yp_innetgr flag immediately after calling setnetgrent() from
innetgr(). We only need the flag set to temporarily alter setnetgrent()'s
behavior. Previously, it was being cleared too late.
- When in NIS-only mode, innetgr() was wasting time doing unecessary
extra processing after it had already found a match.
- Remember to free memory allocated by the NIS functions during innetgr()
searches.
1) Set the persist timer to help time-out connections in the CLOSING state.
2) Honor the keep-alive timer in the CLOSING state.
This fixes problems with connections getting "stuck" due to incompletion
of the final connection shutdown which can be a BIG problem on busy WWW
servers.
Fixed a couple of format strings to match the change of pid_t from long
to int32_t. I only fixed the ones that I noticed the warnings for.
Perhaps most of the format strings are correct now because they were
wrong before. Except of course if int32_t isn't compatible with `int'.
Accept and use the content of packets received that is bigger than the
Novell spec, but still only transmit according to the spec.
Add a feature to dump the RIP and SAP tables when a SIGINFO signal is
received.
Another try: fixed bogus change of the fifo settings for the non-speed of 0.
rev.1.30 incorrectly changed the behaviour from always disabling the fifo
to always enabling it.
Don't use a newfangled auto initializer. Initialize everything by
assignment to avoid one bug and several pessimizations.
In the old version, gcc-2.6.3 (i386 version) generates 16 bytes
of static data and copies it using 4 4-byte load-stores. gcc-2.7.2
generates 2 1-byte stores and calls memset() to zero 14 bytes.
Linking fails because memset() doesn't exist in the kernel.
In both versions, the 2 bytes stored directly are all that is
actually used unless the null padding at the end is used, since
the 3 4-byte words in the middle are initialized again by struct
assignment. These words are misaligned. gcc generates misaligned
load-stores for (small) misaligned struct copies.
Changed _BSD_PID_T_ from long to int. Lite2 changed pid_t from long to
int32_t in <sys/types.h> but this change was missed when the Lite2 types
were merged.
Changed `noreturn' to `__noreturn__' so that all headers don't break if
an application #defines `noreturn'.
Changed one instance of `const' similarly. This is less like to be a
problem since applications shouldn't #define `const', and the common
hack of #defining `const' as nothing gives harmless (?) null attributes
instead of syntax errors.
Eliminated sloppy common-style declarations. Now there are no duplicated
common labels for LINT. There are still some common declarations for the
!KERNEL case in tcp_debug.h and spx_debug.h. trpt depends on the ones in
tcp_debug.h.

Changed all per-file errors to warnings. Exit with a nonzero status of
if there was a per-file error. My test case of `wc /proc/curproc/*'
works reasonably now (much like `size /proc/curproc/*'.
Use PCB_SAVEFPU_SIZE instead of a too-small size in savectx(). This
bug only affected FPU emulators. It might have caused bogus FPU states
in core dumps and in the child pcb after a fork. Emulated FPU states
in core dumps don't work for other reasons, and the child FPU state
is reinitialized by exec, so the problem might not have caused any
noticeable affects.
