* Lock down a socket, milestone 1.tanimura2002-05-201-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Add a mutex (sb_mtx) to struct sockbuf. This protects the data in a socket buffer. The mutex in the receive buffer also protects the data in struct socket. o Determine the lock strategy for each members in struct socket. o Lock down the following members: - so_count - so_options - so_linger - so_state o Remove *_locked() socket APIs. Make the following socket APIs touching the members above now require a locked socket: - sodisconnect() - soisconnected() - soisconnecting() - soisdisconnected() - soisdisconnecting() - sofree() - soref() - sorele() - sorwakeup() - sotryfree() - sowakeup() - sowwakeup() Reviewed by: alfred
* Revert the change of #includes in sys/filedesc.h and sys/socketvar.h.tanimura2002-04-301-3/+5
| | | | | | | | | | Requested by: bde Since locking sigio_lock is usually followed by calling pgsigio(), move the declaration of sigio_lock and the definitions of SIGIO_*() to sys/signalvar.h. While I am here, sort include files alphabetically, where possible.
* Change the suser() API to take advantage of td_ucred as well as do ajhb2002-04-011-1/+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. Discussed on: smp@

* SMP Lock struct file, filedesc and the global file list.alfred2002-01-131-4/+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.dwmalone2001-10-041-2/+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

* Shuffle sysctls a bit (thankyou whoever made them dynamic for modules)julian2001-02-231-1/+0

| | | | | | | | | | | | | This clears out my outstanding netgraph changes. There is a netgraph change of design in the offing and this is to some extent a superset of soem of the new functionality and some of the old functionality that may be removed. This code works as before, but allows some new features that I want to work with and evaluate. It is the basis for a version of netgraph with integral locking for SMP use. This is running on my test machine with no new problems :-)

* Add two new generic control messages, NGM_ASCII2BINARY andarchie1999-11-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | 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. Reviewed by: julian
