Fixed the return value of ptrace for PEEKTEXT and PEEKDATA: return value must
...
be a pointer to data, which holds the result. Linux's glibc undo this odd
operation to bring the standard ptrace behavior to userland.

When c_ospeed in termio is null, NetBSD hangup the terminal. Since Linux
...
does not do this, we fake null c_ospeed values by -1 in the kernel, so
that NetBSD does not hangup.

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.

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
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.

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.

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.
