* Change the suser() API to take advantage of td_ucred as well as do aJohn Baldwin2002-04-012-3/+3
| | | | | | | | | | | | | | | 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.

* Lock struct pgrp, session and sigio.Seigo Tanimura2002-02-231-3/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | New locks are: - pgrpsess_lock which locks the whole pgrps and sessions, - pg_mtx which protects the pgrp members, and - s_mtx which protects the session members. Please refer to sys/proc.h for the coverage of these locks. Changes on the pgrp/session interface: - pgfind() needs the pgrpsess_lock held. - The caller of enterpgrp() is responsible to allocate a new pgrp and session. - Call enterthispgrp() in order to enter an existing pgrp. - pgsignal() requires a pgrp lock held.

* Some fix for the recent apm module changes.Mitsuru IWASAKI2001-11-011-11/+3
| | | | | | | | | | | | | | | | | - Now that apm loadable module can inform its existence to other kernel components (e.g. i386/isa/clock.c:startrtclock()'s TCS hack). - Exchange priority of SI_SUB_CPU and SI_SUB_KLD for above purpose. - Add simple arbitration mechanism for APM vs. ACPI. This prevents the kernel enables both of them. - Remove obsolete `#ifdef DEV_APM' related code. - Add abstracted interface for Powermanagement operations. Public apm(4) functions, such as apm_suspend(), should be replaced new interfaces. Currently only power_pm_suspend (successor of apm_suspend) is implemented.

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