* Changes to MI Linux emulation code necessary to run 32-bit Linux binariesTim J. Robbins2004-08-161-2/+13
| | | | | | | | | | | | | | | | | | on AMD64, and the general case where the emulated platform has different size pointers than we use natively: - declare certain structure members as l_uintptr_t and use the new PTRIN and PTROUT macros to convert to and from native pointers. - declare some structures __packed on amd64 when the layout would differ from that used on i386. - include <machine/../linux32/linux.h> instead of <machine/../linux/linux.h> if compiling with COMPAT_LINUX32. This will need to be revisited before 32-bit and 64-bit Linux emulation support can coexist in the same kernel. - other small scattered changes. This should be a no-op on i386 and Alpha.

* Have SIOCGIFCONF return all (if any) AF_INET addresses for theMarcel Moolenaar2002-01-291-4/+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 Notes: svn path=/head/; revision=89944

* SMP Lock struct file, filedesc and the global file list.Alfred Perlstein2002-01-131-94/+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).

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

* Deal with a few issues that cropped up following the recent changesIan Dowse2001-11-191-14/+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.
