mycroft 605a125097 After an I/O operation completes, immediately set B_BUSY again. Also,
lower spl sooner, and remove an unneeded splbio()/splx() pair.

cgd e9d17d38b5 avoid unnecessary aging of buffers. This used to make sense, when buffer
caches were much smaller, but makes little sense now, and will become more
useless as RAM (and buffer cache) sizes grow.  Suggested by Bob Baron.

cgd b45221af72 prototype strategy and minphys, use & check minphys return value 1995-07-24 07:45:24 +00:00
mycroft 73d0d3717e Don't toss out tty stop signals if we're being traced. 1995-07-24 03:18:42 +00:00
christos 7de0fcfd12 Add KTR_EMUL to indicate a switch between syscall emulations.
Currently this record is emitted only on exec. Maybe it should
be emitted on ktrace() attach too.

cgd f5bbdfba41 bdwrite() should upgrade writes to tape devices by sending them to
bawrite().  it's logically more correct (doesn't return an error code,
because it's async; bdwrite is also async), it still writes things
in-order, it makes sure the proper accountins is done (see the
wasdelayed cases in bwrite()), and it allows writes to vnodes on volumes
mountd with the MNT_ASYNC to be converted into delayed writes the way
God, err, Kirk intended.  Convert synchronous bwrite()s on MNT_ASYNC
file systems to delayed writes.

cgd 9c3fe30d92 fix long-standing XXX in getblk(): NFS does funky things (somewhat
explained in comments), which can cause a race condition.  amazingly,
the _only_ time i've ever seen or heard of this problem was in some
comments and sources by Rick Macklem, and when running against the
a DEC OSF/1 NFS server running on an Alpha.

mycroft 7263209ce6 Make each disk and tape driver define its own read and write functions.
Deprecate rawread() and rawwrite() completely.  Remove d_strategy from cdevsw to
force the abstraction barrier.

cgd 3748c1aef7 try to insure that the 'default' address for shm segments is the same
from process to process.  It apparently is on SysV systems, and some
programs depend on this.  Suggested by  John Birrell <jb@werple.mira.net.au>.

christos 1a5a3c9199 Extracted all of the compat_xxx routines, and created a library [libcompat]
for them. There are a few #ifdef COMPAT_XX remaining, but they are not easy
or worth eliminating (yet).

mycroft d7e904a697 Fix various signal handling bugs:
* If we got a stopping signal while already stopped with the same signal,
the second signal would sometimes (but not always) be ignored.
* Signals delivered by the debugger always pretended to be stopping
signals.
* PT_ATTACH still didn't quite work right.

mycroft 4a975bbe6f If necessary, wake up the child during attach so we always get a SIGCHLD. 1995-06-05 20:57:54 +00:00

case in ttyblock().

jtc 95ded74f58 Moved egid credential from cr_groups[0] to new field cr_gid. POSIX.1
requires that sgid executables and the setuid() syscall *not* change
the supplemental group list.

christos fb371ccef0 tty_tb.c: need to include ioctl_compat.h in order to compile.
sysv_shm.c: make shm_find_segment_by_shmid global so it can be used by
	    COMPAT_HPUX. There should be a better way...
rest: Add #ifdef COMPAT_HPUX where needed

mycroft 78356f06b3 Add two vprint()s, to give more informative panic messages. 1995-05-04 03:11:06 +00:00
cgd 3d9ffd41f3 make this work sanely on a 64-bit machine. Sacrifices a small bit of
error checking in the DIAGNOSTIC case.  These changes might be backed out,
if it's decided that MINBUCKET should be 5 (rather than 4) on the alpha.
However, doing that has its own set of nasty consequences.
1995-05-01 22:39:11 +00:00
cgd 2581c66077 remember first error code (if any) that's different than ENOEXEC.
Not perfect, but there's no perfect solution to the "multiple interesting
error codes" problem.

- deprecate ep_setup
- call sendsig and setregs indirectly.
