* Move the common bits of syscall invocation and return handling intoguenther2012-08-071-40/+11
| | | | | | | | | | an MI file, <sys/syscall_mi.h>, correcting inconsistencies and the handling when copyin() of arguments fails. Tested on i386, amd64, sparc64, and alpha (thanks naddy@) Any issues with other platforms will be fixed in tree. header name from millert@; ok miod@
* Revert previous change, and don't set IFM_AVALID | IFM_ACTIVE in ifm_statusmiod2012-07-301-4/+1

* When reporting media state, be sure to set IFM_AVALID and IFM_ACTIVE inmiod2012-07-251-1/+4
| | | | | | | | ifm_status, for dhclient's sake. Current dhclient interface_status() considers interfaces able to report media information but not returning IFM_AVALID as down. Note that these interfaces usually have mii(4) or have specific code reporting correct values; sparc le(4) is an exception. Found the hard way by sebastia@; joint work with krw@, ok deraadt@

* create new machine/_float.h which is namespace clean. create a newderaadt2012-06-262-54/+35
| | | | | | | | | MI float.h which pulls in and defines the values that are needed from there, and repair sys/limits.h so that it defines the values it needs as well (depending on POSIX version, XPG version, etc). guenther has a more exact selection of that coming for limits.h. this also fixes a few mistakes for the vax. reviewed by kettenis and guenther.
* __tfork() needs to set the stack address of the new thread in the kernel,guenther2012-06-211-7/+11
| | | | | | | | | so that it can't get a signal while still running on the parent thread's stack. Also, pass in sizeof(struct __tfork) to provide forward compat when more members are added. This is an ABI change, so switch syscall numbers and bump lib majors this time. ok deraadt@ matthew@
* Correctly handle the case of a system setup to use glass console, whichmiod2012-05-251-1/+19
| | | | | | | | | | | | | frame buffer has been removed, but which keyboard is left plugged in. The PROM will select a `keyboard input, serial output' console, which was being recognized as glass console by the kernel. The kernel would then reset the serial chip at zstty attach time, while still using the PROM output routines at this point, and hang. Fix this by paying attention to split input/output setups and always falling back to serial console in this case. ok kettenis@

* "TLS-lite": add kernel support for a per-thread userspace pointer,guenther2011-10-152-1/+78
| | | | | | | | | | | for pointing to the thread-control-block. Support for mapping this to the correct hardware register can be added as it's finished; start with support for amd64, sparc, and sparc64. Includes syscalls for getting and setting it (for a portable __errno implementation) as well as creating a new thread with an initial value for it. discussed with miod@, kettenis@, deraadt@; committing to get the syscalls in with the impending libc bump and do further refinements in tree

| | | | | | | uint64_t, depending upon the platform; this makes the declaration of these types consistent accross all our supported platform, and we do not intend to support a platform where bus_addr_t could be larger than the size of the cpu register. Requested by deraadt@ during s2k11

Also, per krw's request, change bounds_check_with_label() to return 0 if the checks succeed, and change the drivers to test == -1 instead of <= 0. (Man page update to follow; intentionally omitting arch/vax/mba/hp.c from this commit because it doesn't even build currently and miod@ promises to kill it soon.) ok krw@
