First incarnation of our Linux emulator or rather compatibility code. This first shot only incorporaties so much functionality that DOOM can run (the X version), signal handling is VERY weak, so is many other things. But it meets my milestone number one (you guessed it - running DOOM). Uses /compat/linux as prefix for loading shared libs, so it won't conflict with our own libs. Kernel must be compiled with "options COMPAT_LINUX" for this to work.

Try to make Linux socket ioctls work.

Mega-commit for Linux emulator update.. This has been stress tested under netscape-2.0 for Linux running all the Java stuff. The scrollbars are now working, at least on my machine. (whew! :-) I'm uncomfortable with the size of this commit, but it's too inter-dependant to easily seperate out. The main changes: COMPAT_LINUX is *GONE*. Most of the code has been moved out of the i386 machine dependent section into the linux emulator itself. The int 0x80 syscall code was almost identical to the lcall 7,0 code and a minor tweak allows them to both be used with the same C code. All kernels can now just modload the lkm and it'll DTRT without having to rebuild the kernel first. Like IBCS2, you can statically compile it in with "options LINUX". A pile of new syscalls implemented, including getdents(), llseek(), readv(), writev(), msync(), personality(). The Linux-ELF libraries want to use some of these. linux_select() now obeys Linux semantics, ie: returns the time remaining of the timeout value rather than leaving it the original value. Quite a few bugs removed, including incorrect arguments being used in syscalls.. eg: mixups between passing the sigset as an int, vs passing it as a pointer and doing a copyin(), missing return values, unhandled cases, SIOC* ioctls, etc. The build for the code has changed. i386/conf/files now knows how to build linux_genassym and generate linux_assym.h on the fly. Supporting changes elsewhere in the kernel: The user-mode signal trampoline has moved from the U area to immediately below the top of the stack (below PS_STRINGS). This allows the different binary emulations to have their own signal trampoline code (which gets rid of the hardwired syscall 103 (sigreturn on BSD, syslog on Linux)) and so that the emulator can provide the exact "struct sigcontext *" argument to the program's signal handlers. The sigstack's "ss_flags" now uses SS_DISABLE and SS_ONSTACK flags, which have the same values as the re-used SA_DISABLE and SA_ONSTACK which are intended for sigaction only. This enables the support of a SA_RESETHAND flag to sigaction to implement the gross SYSV and Linux SA_ONESHOT signal semantics where the signal handler is reset when it's triggered. makesyscalls.sh no longer appends the struct sysentvec on the end of the generated init_sysent.c code. It's a lot saner to have it in a seperate file rather than trying to update the structure inside the awk script. :-) At exec time, the dozen bytes or so of signal trampoline code are copied to the top of the user's stack, rather than obtaining the trampoline code the old way by getting a clone of the parent's user area. This allows Linux and native binaries to freely exec each other without getting trampolines mixed up.

Commit step 1 of the vimage project, (network stack) virtualization work done by Marko Zec (zec@). This is the first in a series of commits over the course of the next few weeks. Mark all uses of global variables to be virtualized with a V_ prefix. Use macros to map them back to their global names for now, so this is a NOP change only. We hope to have caught at least 85-90% of what is needed so we do not invalidate a lot of outstanding patches again. Obtained from: //depot/projects/vimage-commit2/...

Add the CAM 'SG' peripheral device. This device implements a subset of the Linux SCSI SG passthrough device API. The intention is to allow for both running of Linux apps that want to talk to /dev/sg* nodes, and to facilitate porting of apps from Linux to FreeBSD. As such, both native and linuxolator entry points and definitions are provided. Caveats: - This does not support the procfs and sysfs nodes that the Linux SG driver provides. Some Linux apps may rely on these for operation, others may only use them for informational purposes. - More ioctls need to be implemented. - Linux uses a naming scheme of "sg[a-z]" for devices, while FreeBSD uses a scheme of "sg[0-9]". Devfs aliasis (symlinks) are automatically created to link the two together. However, tools like camcontrol only see the native names. - Some operations were originally designed to return byte counts or other data directly as the syscall return value. The linuxolator doesn't appear to support this well, so this driver just punts for these cases. Now that the driver is in place, others are welcome to add missing functionality.

Deal with a few issues that cropped up following the recent changes to the code for translating socket and private ioctls: - Only perform socket ioctl translation if the file descriptor is a socket. - Treat socket ioctls on non-sockets specially, and for now assume that these are directed at a tap/vmnet device, so translate the ioctl numbers as appropriate (the way if_tap abuses some socket ioctls to pass non-ifreq data is utterly bogus, but this is how VMware on FreeBSD has always "worked"; I will deal with this later). - Add (untested) support for translating SIOCSIFADDR. - In all cases where we fail to translate an ioctl, return ENOIOCTL so that other handlers have a chance to do the translation. This should fix the "/dev/vmnet1: Invalid argument" errors that users of VMware were experiencing, though I have only verified this on RELENG_4. Submitted by: des (mostly) MFC after: 3 days

Add support for more linux ioctls. I've had this sitting in my tree for a long time and I can't seem to find who sent it to me in the first place, apologies to whoever is missing out on a Contributed by: line here. I belive it works as it should.

SMP Lock struct file, filedesc and the global file list. Seigo Tanimura (tanimura) posted the initial delta. I've polished it quite a bit reducing the need for locking and adapting it for KSE. Locks: 1 mutex in each filedesc protects all the fields. protects "struct file" initialization, while a struct file is being changed from &badfileops -> &pipeops or something the filedesc should be locked. 1 mutex in each struct file protects the refcount fields. doesn't protect anything else. the flags used for garbage collection have been moved to f_gcflag which was the FILLER short, this doesn't need locking because the garbage collection is a single threaded container. could likely be made to use a pool mutex. 1 sx lock for the global filelist. struct file * fhold(struct file *fp); /* increments reference count on a file */ struct file * fhold_locked(struct file *fp); /* like fhold but expects file to locked */ struct file * ffind_hold(struct thread *, int fd); /* finds the struct file in thread, adds one reference and returns it unlocked */ struct file * ffind_lock(struct thread *, int fd); /* ffind_hold, but returns file locked */ I still have to smp-safe the fget cruft, I'll get to that asap.

Implement pluggable ioctl handlers. Other modules can register and unregister ioctl handlers to extend the ioctls known by the Linuxulator. A recent application is the vmware port. The Linuxulator itself uses the new interface to register its handlers as well. Handlers for the following types of ioctls have been defined: cdrom console (=keyboard and VT handling) socket sound termio All ioctl related defines and declarations have been moved to a new file (linux_ioctl.h), except for the pluggable ioctl handler interface definition. While there, cleanup linux.h some more. linux.h and linux_ioctl.[ch] have been made to conform to style(9) as much as possible. Inspired and reviewed by: Vladimir N. Silyaev

Don't map LINUX_POSIX_VDISABLE to _POSIX_VDISABLE and vice versa for the VMIN and VTIME members of the c_cc array. These members are not special control characters. By not excluding these members we changed the noncanonical mode input processing when both members were 0 on entry (=LINUX_POSIX_VDISABLE) as we would remap them to 255 (=_POSIX_VDISABLE). See termios(4) case A for how that screws up your terminal I/O.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Add TIOCPKT and TIOCSPTLCK to the Linuxolator. We're very lucky, because the flags used by our TIOCPKT implementation are the same as flags used by Linux. We can safely enable TIOCPKT, assuming EXTPROC is not used. TIOCSPTLCK is used by unlockpt(). Because we don't need unlockpt() in our implementation, make this ioctl a no-op.

Linux compat bits needed to make linux programs use the new ptys : linux_ioctl.[ch] : Implement LINUX_TIOCGPTN, which returns the pty number linux_stats.c : - Return the magic number for devfs. - In various stats()-related functions, check that we're stating a file in /dev/pts, and if so, change the st_rdev field to match what linux expects to be there for a slave pty device. The glibc checks for this, and their openpty() fails if it is no correct.

Add TIOCPKT and TIOCSPTLCK to the Linuxolator. We're very lucky, because the flags used by our TIOCPKT implementation are the same as flags used by Linux. We can safely enable TIOCPKT, assuming EXTPROC is not used. TIOCSPTLCK is used by unlockpt(). Because we don't need unlockpt() in our implementation, make this ioctl a no-op.

Implement pluggable ioctl handlers. Other modules can register and unregister ioctl handlers to extend the ioctls known by the Linuxulator. A recent application is the vmware port. The Linuxulator itself uses the new interface to register its handlers as well. Handlers for the following types of ioctls have been defined: cdrom console (=keyboard and VT handling) socket sound termio All ioctl related defines and declarations have been moved to a new file (linux_ioctl.h), except for the pluggable ioctl handler interface definition. While there, cleanup linux.h some more. linux.h and linux_ioctl.[ch] have been made to conform to style(9) as much as possible. Inspired and reviewed by: Vladimir N. Silyaev

Add the CAM 'SG' peripheral device. This device implements a subset of the Linux SCSI SG passthrough device API. The intention is to allow for both running of Linux apps that want to talk to /dev/sg* nodes, and to facilitate porting of apps from Linux to FreeBSD. As such, both native and linuxolator entry points and definitions are provided. Caveats: - This does not support the procfs and sysfs nodes that the Linux SG driver provides. Some Linux apps may rely on these for operation, others may only use them for informational purposes. - More ioctls need to be implemented. - Linux uses a naming scheme of "sg[a-z]" for devices, while FreeBSD uses a scheme of "sg[0-9]". Devfs aliasis (symlinks) are automatically created to link the two together. However, tools like camcontrol only see the native names. - Some operations were originally designed to return byte counts or other data directly as the syscall return value. The linuxolator doesn't appear to support this well, so this driver just punts for these cases. Now that the driver is in place, others are welcome to add missing functionality. Thanks to Roman Divacky for pushing this work along.

First incarnation of our Linux emulator or rather compatibility code. This first shot only incorporaties so much functionality that DOOM can run (the X version), signal handling is VERY weak, so is many other things. But it meets my milestone number one (you guessed it - running DOOM). Uses /compat/linux as prefix for loading shared libs, so it won't conflict with our own libs. Kernel must be compiled with "options COMPAT_LINUX" for this to work.

Add support for the SIOCGIFHWADDR ioctl, commonly used by license managers to obtain the host's ethernet address as a key. Note that this implementation takes the first hardware address for the first ethernet interface found, and disregards the interface name that may be passed in, as linux ethernet devices are all "ethX".

- Change the linux_[gs]et_os{name, release, s_version}() functions to take a thread instead of a proc for their first argument. - Add a mutex to protect the system-wide Linux osname, osrelease, and oss_version variables. - Change linux_get_prison() to take a thread instead of a proc for its first argument and to use td_ucred rather than p_ucred. This is ok because a thread's prison does not change even though it's ucred might. - Also, change linux_get_prison() to return a struct prison * instead of a struct linux_prison * since it returns with the struct prison locked and this makes it easier to safely unlock the prison when we are done messing with it.

- Add support for IPC_64 extensions into shmctl(2), semctl(2) and msgctl(2); - add wrappers for mmap2(2) and ftruncate64(2) system calls; - don't spam console with printf's when VFAT_READDIR_BOTH ioctl(2) is invoked; - add support for SOUND_MIXER_READ_STEREODEVS ioctl(2); - make msgctl(IPC_STAT) and IPC_SET actually working by converting from BSD msqid_ds to Linux and vice versa; - properly return EINVAL if semget(2) is called with nsems being negative.

In continuation of early fileop credential changes, modify fo_ioctl() to accept an 'active_cred' argument reflecting the credential of the thread initiating the ioctl operation. - Change fo_ioctl() to accept active_cred; change consumers of the fo_ioctl() interface to generally pass active_cred from td->td_ucred. - In fifofs, initialize filetmp.f_cred to ap->a_cred so that the invocations of soo_ioctl() are provided access to the calling f_cred. Pass ap->a_td->td_ucred as the active_cred, but note that this is required because we don't yet distinguish file_cred and active_cred in invoking VOP's. - Update kqueue_ioctl() for its new argument. - Update pipe_ioctl() for its new argument, pass active_cred rather than td_ucred to MAC for authorization. - Update soo_ioctl() for its new argument. - Update vn_ioctl() for its new argument, use active_cred rather than td->td_ucred to authorize VOP_IOCTL() and the associated VOP_GETATTR().

Deal with a few issues that cropped up following the recent changes to the code for translating socket and private ioctls: - Only perform socket ioctl translation if the file descriptor is a socket. - Treat socket ioctls on non-sockets specially, and for now assume that these are directed at a tap/vmnet device, so translate the ioctl numbers as appropriate (the way if_tap abuses some socket ioctls to pass non-ifreq data is utterly bogus, but this is how VMware on FreeBSD has always "worked"; I will deal with this later). - Add (untested) support for translating SIOCSIFADDR. - In all cases where we fail to translate an ioctl, return ENOIOCTL so that other handlers have a chance to do the translation. This should fix the "/dev/vmnet1: Invalid argument" errors that users of VMware were experiencing, though I have only verified this on RELENG_4. Submitted by: des (mostly) MFC after: 3 days

Rework global locks for interface list and index management, correcting several critical bugs, including race conditions and lock order issues: Replace the single rwlock, ifnet_lock, with two locks, an rwlock and an sxlock. Either can be held to stablize the lists and indexes, but both are required to write. This allows the list to be held stable in both network interrupt contexts and sleepable user threads across sleeping memory allocations or device driver interactions. As before, writes to the interface list must occur from sleepable contexts. Reviewed by: bz, julian MFC after: 3 days

Rework global locks for interface list and index management, correcting several critical bugs, including race conditions and lock order issues: Replace the single rwlock, ifnet_lock, with two locks, an rwlock and an sxlock. Either can be held to stablize the lists and indexes, but both are required to write. This allows the list to be held stable in both network interrupt contexts and sleepable user threads across sleeping memory allocations or device driver interactions. As before, writes to the interface list must occur from sleepable contexts. Reviewed by: bz, julian MFC after: 3 days

Have SIOCGIFCONF return all (if any) AF_INET addresses for the interfaces we encounter. In Linux, all addresses are returned for which gifconf handlers are installed. This boils down to AF_DECnet and AF_INET. We care mostly about AF_INET for now. Adding additional families is simple enough. Returning the addresses is important for RPC clients to function properly. Andrew found in some reference code that the logic that handles the retransmission looks for an interface that's up and has an AF_INET address. This obviously failed as we didn't return any addresses at all. Note also that with this change we don't return interfaces that don't have AF_INET addresses, whereas before we returned any interface present in the system. This is in line with what Linux does (modulo interfaces with only AF_DECnet addresses of course :-) Reported by: "Andrew Atrens" <atrens@nortelnetworks.com> MFC after: 1 week

Have SIOCGIFCONF return all (if any) AF_INET addresses for the interfaces we encounter. In Linux, all addresses are returned for which gifconf handlers are installed. This boils down to AF_DECnet and AF_INET. We care mostly about AF_INET for now. Adding additional families is simple enough. Returning the addresses is important for RPC clients to function properly. Andrew found in some reference code that the logic that handles the retransmission looks for an interface that's up and has an AF_INET address. This obviously failed as we didn't return any addresses at all. Note also that with this change we don't return interfaces that don't have AF_INET addresses, whereas before we returned any interface present in the system. This is in line with what Linux does (modulo interfaces with only AF_DECnet addresses of course :-) Reported by: "Andrew Atrens" <atrens@nortelnetworks.com> MFC after: 1 week

/* Return all AF_INET addresses of all interfaces */
Rework global locks for interface list and index management, correcting several critical bugs, including race conditions and lock order issues: Replace the single rwlock, ifnet_lock, with two locks, an rwlock and an sxlock. Either can be held to stablize the lists and indexes, but both are required to write. This allows the list to be held stable in both network interrupt contexts and sleepable user threads across sleeping memory allocations or device driver interactions. As before, writes to the interface list must occur from sleepable contexts. Reviewed by: bz, julian MFC after: 3 days

Commit step 1 of the vimage project, (network stack) virtualization work done by Marko Zec (zec@). This is the first in a series of commits over the course of the next few weeks. Mark all uses of global variables to be virtualized with a V_ prefix. Use macros to map them back to their global names for now, so this is a NOP change only. We hope to have caught at least 85-90% of what is needed so we do not invalidate a lot of outstanding patches again. Obtained from: //depot/projects/vimage-commit2/...

Implement pluggable ioctl handlers. Other modules can register and unregister ioctl handlers to extend the ioctls known by the Linuxulator. A recent application is the vmware port.

Try to make Linux socket ioctls work. Up until now they've only *pretended* to work, but haven't really due to subtle differences in structs etc. This is still not perfect (some ioctls are still known not to work, while others haven't been tested at all), but it's enough to get Debian's ifconfig to produce relatively sane output.

Deal with a few issues that cropped up following the recent changes to the code for translating socket and private ioctls: - Only perform socket ioctl translation if the file descriptor is a socket. - Treat socket ioctls on non-sockets specially, and for now assume that these are directed at a tap/vmnet device, so translate the ioctl numbers as appropriate (the way if_tap abuses some socket ioctls to pass non-ifreq data is utterly bogus, but this is how VMware on FreeBSD has always "worked"; I will deal with this later). - Add (untested) support for translating SIOCSIFADDR. - In all cases where we fail to translate an ioctl, return ENOIOCTL so that other handlers have a chance to do the translation. This should fix the "/dev/vmnet1: Invalid argument" errors that users of VMware were experiencing, though I have only verified this on RELENG_4. Submitted by: des (mostly) MFC after: 3 days

Deal with a few issues that cropped up following the recent changes to the code for translating socket and private ioctls: - Only perform socket ioctl translation if the file descriptor is a socket. - Treat socket ioctls on non-sockets specially, and for now assume that these are directed at a tap/vmnet device, so translate the ioctl numbers as appropriate (the way if_tap abuses some socket ioctls to pass non-ifreq data is utterly bogus, but this is how VMware on FreeBSD has always "worked"; I will deal with this later). - Add (untested) support for translating SIOCSIFADDR. - In all cases where we fail to translate an ioctl, return ENOIOCTL so that other handlers have a chance to do the translation. This should fix the "/dev/vmnet1: Invalid argument" errors that users of VMware were experiencing, though I have only verified this on RELENG_4. Submitted by: des (mostly) MFC after: 3 days

Try to make Linux socket ioctls work. Up until now they've only *pretended* to work, but haven't really due to subtle differences in structs etc. This is still not perfect (some ioctls are still known not to work, while others haven't been tested at all), but it's enough to get Debian's ifconfig to produce relatively sane output. More work will be needed to get all ioctls (or at least a reasonable subset) working, and to support the Cisco Aironet config tool mentioned in the PR.

Add the CAM 'SG' peripheral device. This device implements a subset of the Linux SCSI SG passthrough device API. The intention is to allow for both running of Linux apps that want to talk to /dev/sg* nodes, and to facilitate porting of apps from Linux to FreeBSD. As such, both native and linuxolator entry points and definitions are provided. Caveats: - This does not support the procfs and sysfs nodes that the Linux SG driver provides. Some Linux apps may rely on these for operation, others may only use them for informational purposes. - More ioctls need to be implemented. - Linux uses a naming scheme of "sg[a-z]" for devices, while FreeBSD uses a scheme of "sg[0-9]". Devfs aliasis (symlinks) are automatically created to link the two together. However, tools like camcontrol only see the native names. - Some operations were originally designed to return byte counts or other data directly as the syscall return value. The linuxolator doesn't appear to support this well, so this driver just punts for these cases. Now that the driver is in place, others are welcome to add missing functionality. Thanks to Roman Divacky for pushing this work along.
