* First half of implementation of ksiginfo, signal queues, and such. ThisJuli Mallett2002-09-302-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | gets signals operating based on a TailQ, and is good enough to run X11, GNOME, and do job control. There are some intricate parts which could be more refined to match the sigset_t versions, but those require further evaluation of directions in which our signal system can expand and contract to fit our needs. After this has been in the tree for a while, I will make in kernel API changes, most notably to trapsignal(9) and sendsig(9), to use ksiginfo more robustly, such that we can actually pass information with our (queued) signals to the userland. That will also result in using a struct ksiginfo pointer, rather than a signal number, in a lot of kern_sig.c, to refer to an individual pending signal queue member, but right now there is no defined behaviour for such. CODAFS is unfinished in this regard because the logic is unclear in some places.

| | | | | | | | | | | | | | | | | | | | | | | | | 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().

* Make similar changes to fo_stat() and fo_poll() as made earlier toRobert Watson2002-08-161-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fo_read() and fo_write(): explicitly use the cred argument to fo_poll() as "active_cred" using the passed file descriptor's f_cred reference to provide access to the file credential. Add an active_cred argument to fo_stat() so that implementers have access to the active credential as well as the file credential. Generally modify callers of fo_stat() to pass in td->td_ucred rather than fp->f_cred, which was redundantly provided via the fp argument. This set of modifications also permits threads to perform these operations on behalf of another thread without modifying their credential. Trickle this change down into fo_stat/poll() implementations: - badfo_poll(), badfo_stat(): modify/add arguments. - kqueue_poll(), kqueue_stat(): modify arguments. - pipe_poll(), pipe_stat(): modify/add arguments, pass active_cred to MAC checks rather than td->td_ucred. - soo_poll(), soo_stat(): modify/add arguments, pass fp->f_cred rather than cred to pru_sopoll() to maintain current semantics. - sopoll(): moidfy arguments. - vn_poll(), vn_statfile(): modify/add arguments, pass new arguments to vn_stat(). Pass active_cred to MAC and fp->f_cred to VOP_POLL() to maintian current semantics. - vn_close(): rename cred to file_cred to reflect reality while I'm here. - vn_stat(): Add active_cred and file_cred arguments to vn_stat() and consumers so that this distinction is maintained at the VFS as well as 'struct file' layer. Pass active_cred instead of td->td_ucred to MAC and to VOP_GETATTR() to maintain current semantics. - fifofs: modify the creation of a "filetemp" so that the file credential is properly initialized and can be used in the socket code if desired. Pass ap->a_td->td_ucred as the active credential to soo_poll(). If we teach the vnop interface about the distinction between file and active credentials, we would use the active credential here. Note that current inconsistent passing of active_cred vs. file_cred to VOP's is maintained. It's not clear why GETATTR would be authorized using active_cred while POLL would be authorized using file_cred at the file system level.

* - Replace v_flag with v_iflag and v_vflagJeff Roberson2002-08-042-2/+3
| | | | | | | | | | | | | | | | | | - v_vflag is protected by the vnode lock and is used when synchronization with VOP calls is needed. - v_iflag is protected by interlock and is used for dealing with vnode management issues. These flags include X/O LOCK, FREE, DOOMED, etc. - All accesses to v_iflag and v_vflag have either been locked or marked with mp_fixme's. - Many ASSERT_VOP_LOCKED calls have been added where the locking was not clear. - Many functions in vfs_subr.c were restructured to provide for stronger locking.

| | | | | | | | | | | | | | | general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.

* 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.
