We need to remove the old region before mremap() since if it relesae the
old region, other thread may map it for the same huge category allocation
and insert it to the tree before we acquire a lock after mremap().
Fixes PR/42876.
module which is linked into the kernel and cannot be unloaded.
The main purpose is to get the proper constructors run and create
any /dev nodes necessary for said component. Once more of the
kernel (e.g. networking stack and device drivers) are converted to
MODULE and devfs pops up from somewhere, rump components can be
retired.
the source files from src/sys/rump/librump/rumpuser to src/lib/librumpuser
(from where it is already built). Even so, keep rumpuser.h in
sys/rump/include for kernel source tree self-containment.
-call setlocale(LC_CTYPE, "") before nl_langinfo(CODESET) if the
locale settings is (still) at "C" - otherwise the CODESET doesn't work
-fix the type of the WACS_* symbols -- this needs to be cchar_t*
-add safeguards where the return value of wcwidth() is used for
loop counters or indexing -- it can be -1
-use more common code in the widechar support case -- in particular
let the wchar functions do the work even if chtype ones were called
-implement wcursyncup/wsyncup/wsyncdown
-somewhat experimental: allow ACS_* variables to refer to WACS_*
table entries -- this way, programs using the old chtype using API
can use UTF8 line drawing on terminals which support UTF8 but not
ACS switching
-fix some logics bugs in UTF8 recognition and ALTCHARSET handling
if the timezone file fails to load, due to late initialization of sp->goahead
to false in tzload, causing localsub to return NULL in the "cannot happen"
case. The fix is belt and suspenders:
- initialize sp->goback and sp->goahead very early in tzload
- replace all malloc calls with callocs, and remove the bogus
casts (it is not the 70's anymore!)
the standard atomic compare-and-swap operations. Tell some caveats.
Manual page links, *_ni.3 -> atomic_cas.3 are coming up after a
successful 'build.sh distribution'.
