* linux-user: Enable NPTL for m68kPeter Maydell2013-07-221-0/+12
| | | | | | | | | | | For m68k, per-thread data is a purely kernel construct with no CPU level support. Implement it via a field in the TaskState structure, used by cpu_set_tls() and the set_thread_area/get_thread_area syscalls. This allows us to enable compilation with NPTL.

* | linux-user: improve target_to_host_sock_type conversionPetar Jovanovic2013-07-051-18/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous implementation has failed to take into account different value of SOCK_NONBLOCK on target and host, and existence of SOCK_CLOEXEC. The same conversion has to be applied both for do_socket and do_socketpair, so the code has been isolated in a static inline function. enum sock_type in linux-user/socket.h has been extended to include TARGET_SOCK_CLOEXEC and TARGET_SOCK_NONBLOCK, similar to definition in libc. The patch also includes necessary code style changes (tab to spaces) in the header file since most of the file has been touched by this change.

* | linux-user: Fix sys_utimensat (would not compile on old glibc)Peter Maydell2013-07-051-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit c0d472b12e accidentally dropped the definition of __NR_SYS_utimensat even though its use is guarded by CONFIG_UTIMENSAT, not CONFIG_ATFILE. Some older glibc don't have utimensat() (even if they have the other *at() functions). Fix this by correctly cleaning up the sys_utimensat() implementation and #defines, so that we always provide the syscall if needed whether we're doing it via glibc or not.

* linux-user: Drop direct use of openat etc syscallsPeter Maydell2013-06-121-194/+24Star
| | | | | | | | | | | | | | | | | | | | The linux-user syscall emulation layer currently supports the openat family of syscalls via two mechanisms: simply calling the corresponding libc functions, and making direct syscalls. Since glibc has supported these functions since at least glibc 2.5, there's no real need to retain the (essentially untested) direct syscall fallback code, so simply delete it. This allows us to remove some ifdeffery that was attempting to disable provision of some of the syscalls if the host didn't seem to support them, which in some cases was actually wrong (eg where there are several flavours of the syscall and we only need one of them, not necessarily the exact one the guest has, as with the fstatat* calls).

| | | | | | | | | | | | | | | | | | | | | | | | | | The statfs syscall should always memset(0) its full struct extent before writing to it. Newer versions of the syscall use one of the reserved fields for flags, which would otherwise get stale values from uncleaned memory. This fixes libarchive for me, which got confused about the return value of pathconf("/", _PC_REC_XFER_ALIGN) otherwise, as it some times gave old pointers as return value.

| | | | | | | | | | | In case when TARGET_ABI_BITS == 32 && HOST_LONG_BITS == 64, the last byte of the target dirent structure (aka d_type byte) was never copied from the host dirent structure, thus breaking everything that relies on valid d_type value, e.g. glob(3).
