ktrace output, due to range-bounding by binary masking.

7046b15b3d Fixed the return value of ptrace for PEEKTEXT and PEEKDATA: return value must

d473f5bd8a Improved the accuracy of gettimeofday/settimeofday: Linux stores a srtuct 
timezone in the kernel. We now keep track of it for emulated processes.
Tested for powerpc and i386. Untested on m68k, but it should be ok
Alpha has a particular implementation (osf1_sys_gettimeofday), and it has
therefore not been touched.

7e6929fe90 Changed EMUL_BSD_ASYNCIO_PIPE to EMUL_NO_BSD_ASYNCIO_PIPE, so that 
the native emulation (NetBSD) does not have a flag.
 2001-05-07 09:55:12 +00:00
manu
5a6b8191b5 Added two flags to emulation packages: 
EMUL_BSD_ASYNCIO_PIPE notes that the emulated binaries expect the original
BSD pipe behavior for asynchronous I/O, which is to fire SIGIO on read() and
write(). OSes without this flag do not expect any SIGIO to be fired on
read() and write() for pipes, even when async I/O was requested. As far as
we know, the OSes that need EMUL_BSD_ASYNCIO_PIPE are NetBSD, OSF/1 and
Darwin.

EMUL_NO_SIGIO_ON_READ notes that the emulated binaries that requested
asynchrnous I/O expect the reader process to be notified by a SIGIO, but
not the writer process. OSes without this flag expect the reader and the
writer to be notified when some data has arrived or when some data have been
read. As far as we know, the OSes that need EMUL_NO_SIGIO_ON_READ are Linux
and SunOS.

b6d1d4db02 Change the first arg to fileops fo_stat routine to struct file *, adjust 
callers and appropriate routines to cope. This makes fo_stat more
consistent with rest of fileops routines and also makes the fo_stat
match FreeBSD as an added bonus.

2d8e2c19d6 Fix soo_stat() calls for the new parameter, even if the direct call is

things that build on i386 are important. Maybe it's the full moon tonight.

890850dddf Implement linux_sys_nosys() and use it instead of sys_nosys() for 
unimplemented syscalls. Difference is that linux_sys_nosys() doesn't
post SIGSYS to the process. Linux doesn't do that and thus glibc (and
probably other Linux code) doesn't deal with SIGSYS, even through it
generally contains fallback code for ENOSYS case.

This also addresses port-i386/12503, though the issue was already discussed
earlier.

569cf4b764 Use parent's vmspace in linux_e_proc_fork() hook, the child does not 
have vmspace setup yet. This fixes lossage discussed on current-users,
thread "hard lockups with -current and Netscape", and should fix
kern/12433 by <kawamoto@tenjin.org>, maybe also kern/12455.

XXX Threads forked via linux_sys_clone() should share the brk value
XXX if they share vmspace. This needs to be implemented.
