Remove old files no longer needed. Add new files created for emulator. Modify NetBSD import to work with FreeBSD and add new features and code. The complete emulator is essentially a combination of work/code implemented by Sean Eric Fagan, Soren Schmidt, Scott Bartram, and myself, Steven Wallace. Features of this new emulator system include: o "clean" code, including strict prototyping. o Auto-generation of ibcs2 system calls, xenix system calls, isc system calls. Generation includes system tables, structure definitions, and prototyping of function calls. o ibcs2 emulator does not rely on any COMPAT_43 system calls. o embedded socksys support o ibcs2 msgsys, semsys, shmsys calls supported if supported in kernel o alternate /emul/ibcs2 namespace searched first for files in ibcs2 system. Usefull to keep sysv libraries, binaries in /emul/ibcs2. o many other finer details and functions fixed or implemented.

This is what was "fdfix2.patch," a fix for fd sharing. It's pretty far-reaching in fd-land, so you'll want to consult the code for changes. The biggest change is that now, you don't use fp->f_ops->fo_foo(fp, bar) but instead fo_foo(fp, bar), which increments and decrements the fp refcount upon entry and exit. Two new calls, fhold() and fdrop(), are provided. Each does what it seems like it should, and if fdrop() brings the refcount to zero, the fd is freed as well. Thanks to peter ("to hell with it, it looks ok to me.") for his review. Thanks to msmith for keeping me from putting locks everywhere :) Reviewed by: peter

Remove old files no longer needed. Add new files created for emulator. Modify NetBSD import to work with FreeBSD and add new features and code. The complete emulator is essentially a combination of work/code implemented by Sean Eric Fagan, Soren Schmidt, Scott Bartram, and myself, Steven Wallace. Features of this new emulator system include: o "clean" code, including strict prototyping. o Auto-generation of ibcs2 system calls, xenix system calls, isc system calls. Generation includes system tables, structure definitions, and prototyping of function calls. o ibcs2 emulator does not rely on any COMPAT_43 system calls. o embedded socksys support o ibcs2 msgsys, semsys, shmsys calls supported if supported in kernel o alternate /emul/ibcs2 namespace searched first for files in ibcs2 system.

Remove old files no longer needed. Add new files created for emulator. Modify NetBSD import to work with FreeBSD and add new features and code. The complete emulator is essentially a combination of work/code implemented by Sean Eric Fagan, Soren Schmidt, Scott Bartram, and myself, Steven Wallace. Features of this new emulator system include: o "clean" code, including strict prototyping. o Auto-generation of ibcs2 system calls, xenix system calls, isc system calls. Generation includes system tables, structure definitions, and prototyping of function calls. o ibcs2 emulator does not rely on any COMPAT_43 system calls. o embedded socksys support o ibcs2 msgsys, semsys, shmsys calls supported if supported in kernel o alternate /emul/ibcs2 namespace searched first for files in ibcs2 system. Usefull to keep sysv libraries, binaries in /emul/ibcs2. o many other finer details and functions fixed or implemented.

Features of this new emulator system include: o "clean" code, including strict prototyping. o Auto-generation of ibcs2 system calls, xenix system calls, isc system calls. Generation includes system tables, structure definitions, and prototyping of function calls. o ibcs2 emulator does not rely on any COMPAT_43 system calls. o embedded socksys support o ibcs2 msgsys, semsys, shmsys calls supported if supported in kernel o alternate /emul/ibcs2 namespace searched first for files in ibcs2 system.

Remove old files no longer needed. Add new files created for emulator. Modify NetBSD import to work with FreeBSD and add new features and code. The complete emulator is essentially a combination of work/code implemented by Sean Eric Fagan, Soren Schmidt, Scott Bartram, and myself, Steven Wallace. Features of this new emulator system include: o "clean" code, including strict prototyping. o Auto-generation of ibcs2 system calls, xenix system calls, isc system calls. Generation includes system tables, structure definitions, and prototyping of function calls. o ibcs2 emulator does not rely on any COMPAT_43 system calls. o embedded socksys support o ibcs2 msgsys, semsys, shmsys calls supported if supported in kernel o alternate /emul/ibcs2 namespace searched first for files in ibcs2 system. Usefull to keep sysv libraries, binaries in /emul/ibcs2. o many other finer details and functions fixed or implemented.
