* MFC r216572:Konstantin Belousov2010-12-261-0/+1

* MFC r215708:Bernhard Schmidt2010-11-264-8/+95
| | | | | | | | | | | | | | | | Resurrect amd64 support. - Many drivers on amd64 are picking system uptime, interrupt time and ticks via global data structure instead of calling functions for performance reasons. For now just patch such address so driver will not trigger page fault when trying to access such data. In future, additional callout may be added to update data in periodic intervals. - On amd64 we need to allocate "shadow space" on stack before calling any function.

* MFC r215338:Alexander Leidinger2010-11-222-15/+54
| | | | | | | | | | | | | | | | | | | | | - print out the PID and program name of the program trying to use an unsupported futex operation - for those futex operations which are known to be not supported, print out which futex operation it is - shortcut the error return of the unsupported FUTEX_CLOCK_REALTIME in some cases: FUTEX_CLOCK_REALTIME can be used to tell linux to use CLOCK_REALTIME instead of CLOCK_MONOTONIC. FUTEX_CLOCK_REALTIME however must only be set, if either FUTEX_WAIT_BITSET or FUTEX_WAIT_REQUEUE_PI are set too. If that's not the case we can die with ENOSYS right at the beginning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reorganize syscall entry and leave handling. Implement ptrace_lwpinfo pl_flags PL_FLAG_SCE, PL_FLAG_SCX and PL_FLAG_EXEC. The i386, amd64, sparc64, sun4v, powerpc and ia64 syscall()s are changed to use syscallenter()/syscallret(). MIPS and arm are not converted and use the mostly unchanged syscall() implementation. MFC r208514: Change ia64' struct syscall_args definition so that args is a pointer to the arguments array instead of array itself. MFC r208566: Allow to use syscallname(9) outside subr_trap.c. MFC r209258 (by rpaulo): Make DTrace syscall provider work again by including opt_kdtrace.h here. MFC r209313: Only enable kdtrace hook in the LINT on the architectures that implement it. MFC r209697: Obey sv_syscallnames bounds in syscallname(). NOTE: The KBI of the struct sysentvec is changed, new required members sv_set_syscall_retval, sv_fetch_syscall_args and sv_syscallnames are added. The sv_prepsyscall field is now ignored. Third-party modules using the struct sysentvec must be modified and recompiled, we believe that only ABI emulators are affected. No such out-of-tree modules are known. In-tree modules that are affected by the change were converted to depend on exact version of the kernel, see r214421. Notes: svn path=/stable/8/; revision=214755
* MFC r213716:Konstantin Belousov2010-10-271-1/+1
| | | | | | | | | | | | | | | Add macro DECLARE_MODULE_TIED to denote a module as requiring the kernel of exactly the same __FreeBSD_version as the headers module was compiled against. Mark our in-tree ABI emulators with DECLARE_MODULE_TIED. The modules use kernel interfaces that the Release Engineering Team feel are not stable enough to guarantee they will not change during the life cycle of a STABLE branch. In particular, the layout of struct sysentvec is declared to be not part of the STABLE KBI. Notes: svn path=/stable/8/; revision=214421

| | | | | | | | | | | | | | | | | | | | Replace the static NGROUPS=NGROUPS_MAX+1=1024 with a dynamic kern.ngroups+1. kern.ngroups can range from NGROUPS_MAX=1023 to somewhere in the neighborhood of INT_MAX/4 one a system with sufficent RAM and memory bandwidth. Given that the Windows group limit is 1024, this range should be sufficient for most applications r202342: Only allocate the space we need before calling kern_getgroups instead of allocating what ever the user asks for up to "ngroups_max + 1". On systems with large values of kern.ngroups this will be more efficient. The now redundant check that the array is large enough in kern_getgroups() is deliberate to allow this change to be merged to stable/8 without breaking potential third party consumers of the API.
