* Have SIOCGIFCONF return all (if any) AF_INET addresses for themarcel2002-01-291-4/+22
| | | | | | | | | | | | | | | | | | | | | 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

* SMP Lock struct file, filedesc and the global file list.alfred2002-01-131-94/+184
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | properly translate the interface name passed to us, make sure we also translate correctly before we return the list of interfaces with the SIOCGIFCONF ioctl. It is common to use the interface names returned by that ioctl in further ioctls, such as SIOCGIFFLAGS. Remove linux_ifname as it is no longer used. Also remove ifname_bsd_to_linux as it cannot be used anymore now that linux_ifname is removed (was deadcode anyway). Reported and tested by: Andrew Atrens <atrens@nortelnetworks.com>

* When translating the interface name when "eth?" is given, do notmarcel2001-12-041-3/+9
| | | | | | | | | | | | | | use the internal index number as the unit number to compare with. The first ethernet interface in Linux is called "eth0", whereas our internal index starts wth 1 and is not unique to ethernet interfaces (lo0 has index 1 for example). Instead, use a function- local index number that starts with 0 and is incremented only for ethernet interfaces. This way the unit number will match the n-th ethernet interface in the system, which is exactly what it means in Linux. Tested by: Glenn Johnson <gjohnson@srrc.ars.usda.gov> MFC after: 3 days
* Deal with a few issues that cropped up following the recent changesiedowse2001-11-191-14/+69
| | | | | | | | | | | | | | | | | | | | | | | 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

* Fix Alpha related brokenness. We used to have a MD linux_ioctl.hmarcel2001-10-191-6/+30
| | | | | | | | | | | | | | | | | that appeared to be very different from the MI version. These differences were mostly bogus and caused by copying octal definitions and write them as hexadecimal values without doing any base conversion (ie 010 was copied to 0x10). After filtering out these differences, any remaining (real) incompatibilities have been merged into the MI header file to make them more visible. While here, fix the termios <-> termio conversion WRT to the c_cc field for Alpha. The termios values do not match the termio values and thus prevents us from copying. By eliminating the Alpha MD copy of linux_ioctl.h we also fixed the recent build breakage caused by putting new bits in the MI header and not in the MD header.
* Add support for the "device private" ioctls soon to be used by the an driver.des2001-10-191-16/+63

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Introduce private types for use in linux syscalls for two reasons: 1. establish type independence for ease in porting and, 2. provide a visual queue as to which syscalls have proper prototypes to further cleanup the i386/alpha split. Linuxulator types are prefixed by 'l_'. void and char have not been "virtualized". o Provide dummy functions for all syscalls and remove dummy functions or implementations of truely obsolete syscalls. o Sanitize the shm*, sem* and msg* syscalls. o Make a first attempt to implement the linux_sysctl syscall. At this time it only returns one MIB (KERN_VERSION), but most importantly, it tells us when we need to add additional sysctls :-) o Bump the kenel version up to 2.4.2 (this is not the same as the KERN_VERSION MIB, BTW). o Implement new syscalls, of which most are specific to i386. Our syscall table is now up to date with Linux 2.4.2. Some highlights: - Implement the 32-bit uid_t and gid_t bases syscalls. - Implement a couple of 64-bit file size/offset bases syscalls. o Fix or improve numerous syscalls and prototypes. o Reduce style(9) violations while I'm here. Especially indentation inconsistencies within the same file are addressed. Re-indenting did not obfuscate actual changes to the extend that it could not be combined. NOTE: I spend some time testing these changes and found that if there were regressions, they were not caused by these changes AFAICT. It was observed that installing a RH 7.1 runtime environment did make matters worse. Hangs and/or reboots have been observed with and without these changes, so when it failed to make life better in cases it doesn't look like it made it worse.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the a.out emulation of 'struct linker_set' with something a little more flexible. <sys/linker_set.h> now provides macros for accessing elements and completely hides the implementation. The linker_set.h macros have been on the back burner in various forms since 1998 and has ideas and code from Mike Smith (SET_FOREACH()), John Polstra (ELF clue) and myself (cleaned up API and the conversion of the rest of the kernel to use it). The macros declare a strongly typed set. They return elements with the type that you declare the set with, rather than a generic void *. For ELF, we use the magic ld symbols (__start_<setname> and __stop_<setname>). Thanks to Richard Henderson <rth@redhat.com> for the trick about how to force ld to provide them for kld's. For a.out, we use the old linker_set struct. NOTE: the item lists are no longer null terminated. This is why the code impact is high in certain areas. The runtime linker has a new method to find the linker set boundaries depending on which backend format is in use. linker sets are still module/kld unfriendly and should never be used for anything that may be modular one day.

| | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | 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.
