[PATCH v2 0/9] bsd-user mmap fixes

Posted by Warner Losh 2 years, 7 months ago

This series synchronizes mmap.c with the bsd-user fork. This is a mix of old bug
fixes pulled in from linux-user, as well as some newer fixes to adress bugs
found in check-tcg and recent FreeBSD developments. There are also a couple of
style commits.

v2: do the cherry-picks from linux-user in qemu-style.

Guy Yur (1):
  bsd-user/mmap.c: Don't mmap fd == -1 independently from MAP_ANON flag

Kyle Evans (1):
  bsd-user/mmap.c: Implement MAP_EXCL, required by jemalloc in head

Mikaël Urankar (2):
  bsd-user/mmap.c: Always zero MAP_ANONYMOUS memory in mmap_frag()
  bsd-user/mmap.c: check pread's return value to fix warnings with
    _FORTIFY_SOURCE

Warner Losh (5):
  bsd-user/mmap.c: MAP_ symbols are defined, so no need for ifdefs
  bsd-user/mmap.c: mmap return ENOMEM on overflow
  bsd-user/mmap.c: mmap prefer MAP_ANON for BSD
  bsd-user/mmap.c: line wrap change
  bsd-user/mmap.c: assert that target_mprotect cannot fail
