this declaration is wrong: the correct prototype on linux is: int setgroups(size_t size, const gid_t *list); since by default musl libc exposes this symbol in unistd.h additionally to grp.h, the wrong declaration causes a build error. the proper fix is to simply include the correct header.

2012-12-08linux-user: Merge pread/pwrite into pread64/pwrite64Peter Maydell
The Linux syscalls underlying pread() and pwrite() take a 64 bit offset on all architectures, even if some of them name the syscall "pread/pwrite" rather than "pread64/pwrite64" for historical reasons. So move the four QEMU target architectures (arm, i386, sparc, unicore32) which were defining TARGET_NR_pread/pwrite to define TARGET_NR_pread64/pwrite64 instead, and drop the TARGET_NR_pread/pwrite implementation code completely.

When reading our faked /proc/self/maps from a secondary thread, we get an invalid stack entry. This is because ts->stack_base is not initialized in non-primary threads.

2012-10-12linux-user: fix statfsAlexander Graf
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.

If the host's page size is equal to or smaller than the target's, native execve() will fail appropriately with E2BIG if called with too big an environment for the target to handle. It may falsely succeed, however, if the host's page size is bigger, and feed the executed target process an environment that is too big for it to handle, at which point QEMU barfs and exits, confusing procmail's autoconf script and causing the build to fail.
