[Qemu-devel] [PATCH 0/2] linux-user: Support prctl PR_GET/SET_NAME
These patches add support for the prctl options PR_GET_NAME and PR_SET_NAME. In particular, perl 5.14 will use PR_SET_NAME if you change the value of $0, which means that adduser will fail if run under qemu with a sufficiently modern perl. Patch one is just indentation cleanup, the meat is patch 2. The only other prctl options which take pointer arguments are all architecture specific, so there didn't seem much point in adding them (they all work like PR_GET_PDEATHSIG in that they pass an int* to be filled in); we'd have to actually emulate them if we cared about them.

Hello, 2012/2/22 Peter Maydell : > Ping? In case it helps, I have successfully tested this patch running adduser on Debian armhf target emulated via qemu-arm-static.
