use the user-supplied point to lookup which region to perform brk() on,
and if it's a reasonable one, do it, no matter what vm's notion of the
heap region is.
This Shared Folders File System library (libsffs) now contains all the
file system logic originally in HGFS. The actual HGFS server code is
now a stub that passes on all the work to libsffs. The libhgfs library
is changed accordingly.
. remove some call cycles by low-level functions invoking printf(); e.g.
send_sig() gets a return value that the caller should check
. reason: very-early-phase printf() would trigger a printf() causing
infinite recursion -> GPF
. move serial initialization a little earlier so DEBUG_EXTRA works for
serial earlier (e.g. its first instance, for "cstart")
. closes tracker item 583:
System Fails to Complete Startup with Verbose 2 and 3 Boot Parameters,
reported by Stephen Hatton / pikpik.
You might have to update the compiler-rt package! See UPDATING.
. the purpose of this -L was solely to find compiler-rt, which contains
runtime support code for clang-compiled binaries
. this also makes all other packaged libraries visible, however
. it is cleaner to isolate the base system from packages, and so
compiler-rt puts itself in /usr/pkg/compiler-rt/lib/ too, which the
base system henceforth uses exclusively
. e.g. this solves a link failure when libfetch is installed as a
package
. the new compiler-rt package also puts itself in /usr/pkg/lib for 'old'
systems; that is harmless. The benefit of 'new' systems is that the other
packages are hidden.
. fixes e.g. ssh sessions not getting their own
controlling tty (causing ^C getting broadcast to too
many processes)
. previously (before -lutil) handled like this by bsd-openpty.c in
openssh
. reported by Andy Kosela, debugged by ThomasV
Previously, the mmap address (if given) was merely used as a lower
bound, and then possibly overriden with a hint. Now, the mapping is
first tried at the exact given address. If that fails, the start of
the mmap range is used as lower bound (which is then still overridden
by the hint for efficiency).
This allows two pages to be mapped in at predefined addresses, where
the second address is lower than the first. That was not possible.
remove some old minix-userland-specific stuff
. /etc/ttytab as a file, and minix-compat function (fftyslot()),
replaced by /etc/ttys and new libc functions
. also remove minix-specific nlist(), cuserid(), fttyslot(), v8 regex
functions and <compat/regex.h>
. and remaining minix-only utilities that use them
. also unused <compat/pwd.h> and <compat/syslog.h> and
redundant <sys/sigcontext.h>
