* 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@

* Change the kernel's ucred API as follows:jhb2001-10-111-4/+2
| | | | | | | | - crhold() returns a reference to the ucred whose refcount it bumps. - crcopy() now simply copies the credentials from one credential to another and has no return value. - a new crshared() primitive is added which returns true if a ucred's refcount is > 1 and false (0) otherwise.

(but only allow one thread per process at this time). This is functionally equivalent to teh previousl -current except that there is a thread associated with each process. Sorry john!

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

| | | | | | | | | | | | | - Since polling should not involve sleeping, keep holding a process lock upon scanning file descriptors. - Hold a reference to every file descriptor prior to entering polling loop in order to avoid lock order reversal between lockmgr and p_mtx upon calling fdrop() in fo_poll().

* Implement m_getm() which will perform an "all or nothing" mbuf + clusterbmilekic2001-02-141-27/+2
| | | | | | | | | | | | | | | | | | | | | allocation, as required. If m_getm() receives NULL as a first argument, then it allocates `len' (second argument) bytes worth of mbufs + clusters and returns the chain only if it was able to allocate everything. If the first argument is non-NULL, then it should be an existing mbuf chain (e.g. pre-allocated mbuf sitting on a ring, on some list, etc.) and so it will allocate `len' bytes worth of clusters and mbufs, as needed, and append them to the tail of the passed in chain, only if it was able to allocate everything requested. If allocation fails, only what was allocated by the routine will be freed, and NULL will be returned. Also, get rid of existing m_getm() in netncp code and replace calls to it to calls to this new generic code. Heavily Reviewed by: bp

* * Rename M_WAIT mbuf subsystem flag to M_TRYWAIT.bmilekic2000-12-212-9/+9
| | | | | | | | | | | | | | | | | | This is because calls with M_WAIT (now M_TRYWAIT) may not wait forever when nothing is available for allocation, and may end up returning NULL. Hopefully we now communicate more of the right thing to developers and make it very clear that it's necessary to check whether calls with M_(TRY)WAIT also resulted in a failed allocation. M_TRYWAIT basically means "try harder, block if necessary, but don't necessarily wait forever." The time spent blocking is tunable with the kern.ipc.mbuf_wait sysctl. M_WAIT is now deprecated but still defined for the next little while. * Fix a typo in a comment in mbuf.h * Fix some code that was actually passing the mbuf subsystem's M_WAIT to malloc(). Made it pass M_WAITOK instead. If we were ever to redefine the value of the M_WAIT flag, this could have became a big problem.
