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 bsd-user/mmap.c | 69 +++++++++++++++++++++++++------------------------ 1 file changed, 35 insertions(+), 34 deletions(-) -- 2.32.0
