* When making a peer of unknown type framework tries to load moduleGleb Smirnoff2004-07-271-0/+34
| | | | | | | | | | | | | | | | | using linker_load_module(). This works OK if NGM_MKPEER message came from userland and we have process associated with thread. But when NGM_MKPEER was queued because target node was busy, linker_load_module() is called from netisr thread leading to panic. To workaround that we do not load modules by framework, instead ng_socket loads module (if this is required) before sending NGM_MKPEER. However, the race condition between return from NgSendMsg() and actual creation of node still exist and needs to be solved. PR: kern/62789 Approved by: julian Notes: svn path=/head/; revision=132705

* Introduce a MAC label reference in 'struct inpcb', which cachesRobert Watson2003-11-181-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the MAC label referenced from 'struct socket' in the IPv4 and IPv6-based protocols. This permits MAC labels to be checked during network delivery operations without dereferencing inp->inp_socket to get to so->so_label, which will eventually avoid our having to grab the socket lock during delivery at the network layer. This change introduces 'struct inpcb' as a labeled object to the MAC Framework, along with the normal circus of entry points: initialization, creation from socket, destruction, as well as a delivery access control check. For most policies, the inpcb label will simply be a cache of the socket label, so a new protocol switch method is introduced, pr_sosetlabel() to notify protocols that the socket layer label has been updated so that the cache can be updated while holding appropriate locks. Most protocols implement this using pru_sosetlabel_null(), but IPv4/IPv6 protocols using inpcbs use the the worker function in_pcbsosetlabel(), which calls into the MAC Framework to perform a cache update. Biba, LOMAC, and MLS implement these entry points, as do the stub policy, and test policy.

* Change the suser() API to take advantage of td_ucred as well as do aJohn Baldwin2002-04-011-1/+1
| | | | | | | | | | | | | | | 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.

* SMP Lock struct file, filedesc and the global file list.Alfred Perlstein2002-01-131-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Hopefully improve control message passing over Unix domain sockets.David Malone2001-10-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Allow the sending of more than one control message at a time over a unix domain socket. This should cover the PR 29499. 2) This requires that unp_{ex,in}ternalize and unp_scan understand mbufs with more than one control message at a time. 3) Internalize and externalize used to work on the mbuf in-place. This made life quite complicated and the code for sizeof(int) < sizeof(file *) could end up doing the wrong thing. The patch always create a new mbuf/cluster now. This resulted in the change of the prototype for the domain externalise function. 4) You can now send SCM_TIMESTAMP messages. 5) Always use CMSG_DATA(cm) to determine the start where the data in unp_{ex,in}ternalize. It was using ((struct cmsghdr *)cm + 1) in some places, which gives the wrong alignment on the alpha. (NetBSD made this fix some time ago). This results in an ABI change for discriptor passing and creds passing on the alpha. (Probably on the IA64 and Spare ports too). 6) Fix userland programs to use CMSG_* macros too. 7) Be more careful about freeing mbufs containing (file *)s. This is made possible by the prototype change of externalise. PR: 29499 MFC after: 6 weeks Notes: svn path=/head/; revision=84472

| | | | | | | | | | | | | | | | | | | | | | | | | | NGM_BINARY2ASCII, which convert control messages to ASCII and back. This allows control messages to be sent and received in ASCII form using ngctl(8), which makes ngctl a lot more useful. This also allows all the type-specific debugging code in libnetgraph to go away -- instead, we just ask the node itself to do the ASCII translation for us. Currently, all generic control messages are supported, as well as messages associated with the following node types: async, cisco, ksocket, and ppp. See /usr/share/examples/netgraph/ngctl for an example of using this. Also give ngctl(8) the ability to print out incoming data and control messages at any time. Eventually nghook(8) may be subsumed. Several other misc. bug fixes.
