Change malloc/strdup/free to g_malloc/g_strdup/g_free in util/envlist.c. Remove NULL checks for pointers returned from g_malloc and g_strdup as they exit in case of failure. Also, update calls to envlist_create to reflect this. Free array and array contents returned by envlist_to_environ using g_free in bsd-user/main.c and linux-user/main.c.

2017-05-04target/openrisc: implement shadow registersStafford Horne
Shadow registers are part of the openrisc spec along with sr[cid], as part of the fast context switching feature. When exceptions occur, instead of having to save registers to the stack if enabled the CID will increment and a new set of registers will be available. This patch only implements shadow registers which can be used as extra scratch registers via the mfspr and mtspr if required. This is implemented in a way where it would be easy to add on the fast context switching, currently cid is hardcoded to 0. This is need for openrisc linux smp kernels to boot correctly.

2017-02-27syscall: fixed mincore(2) not failing with ENOMEMFranklin \"Snaipe\" Mathieu
The current implementation of the mincore(2) syscall sets errno to EFAULT when the region identified by the first two parameters is invalid.

2017-02-27linux-user: fix do_rt_sigreturn on m68k linux userspace emulationMichael Karcher
do_rt_sigreturn uses an uninitialised local variable instead of fetching the old signal mask directly from the signal frame when restoring the mask, so the signal mask is undefined after do_rt_sigreturn. As the signal frame data is in target-endian order, target_to_host_sigset instead of target_to_host_sigset_internal is required. do_sigreturn is correct in using target_to_host_sigset_internal, because get_user already did the endianness conversion.

2017-02-27linux-user: fix fork()Laurent Vivier
Since commit 5ea2fc8 ("linux-user: Sanity check clone flags"), trying to run fork() fails with old distro on some architectures. This is the case with HP-PA and Debian 5 (Lenny). It fails on: if ((flags & CSIGNAL) != TARGET_SIGCHLD) { return -TARGET_EINVAL; } because flags is 17, whereas on HP-PA, SIGCHLD is 18. 17 is the SIGCHLD value of my host (x86_64). It appears that for TARGET_NR_fork and TARGET_NR_vfork, QEMU calls do_fork() with SIGCHLD instead of TARGET_SIGCHLD.

2017-02-16linux-user: Use correct types in load_symbols()Peter Maydell
Coverity doesn't like the code in load_symbols() which assumes it can use 'int' for a variable that might hold an offset into the guest ELF file, because in a 64-bit guest that could overflow. Guest binaries with 2GB sections aren't very likely and this isn't a security issue because we fully trust the guest linux-user binary anyway, but we might as well use the right types, which will placate Coverity. Use uint64_t to hold section sizes, and bail out if the symbol table is too large rather than just overflowing an int.
