Andrew Griffiths reports that -runas does not set supplementary group IDs. This means that gid 0 (root) is not dropped when switching to an unprivileged user. Add an initgroups(3) call to use the -runas user's /etc/groups membership to update the supplementary group IDs.

This bug was introduced in 94d3f98a: scsi_cancel_io was checking if some request was pending before trying to cancel it, while scsi_req_cancel always cancels the request. This may lead to a crash of Qemu due to dereferencing a NULL pointer, as exhibited by NetBSD 5.1 installer on MIPS Magnum emulation.

Remove the include of setjmp.h from the cpu.h of target-alpha and target-ppc. This is unnecessary because cpu-defs.h already includes this header; this change brings these two targets into line with all the rest.

Some versions of png.h cannot be included after setjmp.h, even when PNG_SKIP_SETJMP_CHECK was defined. setjmp.h was included from qemu-common.h and is not needed there. Removing the include statement fixes compilation of ui/vnc-enc-tight.c with CONFIG_VNC_PNG defined.

Recent compilers look deep into cpu_exec, find longjmp as a noreturn function and decide to smash some stack variables as they won't be used again. This may lead to env becoming invalid after return from setjmp, causing crashes. Fix it by reloading env from cpu_single_env in that case.

The target-arm frontend's worst-case TCG ops per instr is 194 (and in general many of the "load multiple registers" ARM instructions generate more than 100 TCG ops). Raise MAX_OP_PER_INSTR accordingly to avoid possible buffer overruns. Since it doesn't make any sense for the "64 bit guest on 32 bit host" case to have a smaller limit than the normal case, we collapse the two cases back into each other again. (This increase costs us about 14K in extra static buffer space and 21K of extra margin at the end of a 32MB codegen buffer.)

When calculating the point at which we should not try to put another TB into the code gen buffer, we have to allow not just for OPC_MAX_SIZE but OPC_BUF_SIZE. This is because the target translate.c will only stop when an instruction has put it past the OPC_MAX_SIZE limit, so we have to include the MAX_OP_PER_INSTR margin which that final insn might have used.

Device code some times needs to access physical memory and does that through the ld./st._phys functions. However, these are the exact same functions that the CPU uses to access memory, which means they will be endianness swapped depending on the target CPU. However, devices don't know about the CPU's endianness, but instead access memory directly using their own interface to the memory bus, so they need some way to read data with their native endianness. This patch adds _le and _be functions to ld./st._phys. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

This fixes https://bugs.launchpad.net/qemu/+bug/786209: When the DRQ_STAT bit is set, the IDE core permits both data reads and data writes, regardless of whether the current transfer was initiated as a read or write. This potentially leaks uninitialized host memory into the guest, if, before doing anything else to an IDE device, the guest begins a write transaction (e.g. WIN_WRITE), but then *reads* from the IO port instead of writing to it.

On Linux x86_64 host with 32bit userspace, running qemu or even just "qemu-img create -f qcow2 some.img 1G" causes a kernel warning: ioctl32(qemu-img:5296): Unknown cmd fd(3) cmd(00005326){t:'S';sz:0} arg(7fffffff) on some.img ioctl32(qemu-img:5296): Unknown cmd fd(3) cmd(801c0204){t:02;sz:28} arg(fff77350) on some.img ioctl 00005326 is CDROM_DRIVE_STATUS, ioctl 801c0204 is FDGETPRM. The warning appears because the Linux compat-ioctl handler for these ioctls only applies to block devices, while qemu also uses the ioctls on plain files. Work around by calling fstat() the ensure the ioctls are only used on block devices. Signed-off-by: NJohannes Stezenbach <js@sig21.net> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

qemu-img currently writes disk images using writeback and filling up the cache buffers which are then flushed by the kernel preventing other processes from accessing the storage. This is particularly bad in cluster environments where time-based algorithms might be in place and accessing the storage within certain timeouts is critical. This patch adds the option to choose a cache method when writing disk images. Signed-off-by: NFederico Simoncelli <fsimonce@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>
