2014-04-25seccomp: add shmctl(), mlock(), and munlock() to the syscall whitelistPaul Moore1-1/+4
Additional testing reveals that PulseAudio requires shmctl() and the mlock()/munlock() syscalls on some systems/configurations. As before, on systems that do require these syscalls, the problem can be seen with the following command line: # qemu -monitor stdio -sandbox on \ -device intel-hda -device hda-duplex Signed-off-by: Paul Moore <pmoore@redhat.com> Signed-off-by: Eduardo Otubo <otubo@linux.vnet.ibm.com>

2014-04-25iscsi: Don't use error_is_set() to suppress additional errorsMarkus Armbruster1-5/+4
Using error_is_set(errp) that way can sweep programming errors under the carpet when we get called incorrectly with an error set. Commit 24d3bd6 added a broken error path to iscsi_do_inquiry(): it first calls error_setg(), then jumps to the preexisting error label, where error_setg() gets called again, triggering an assertion failure. Commit cbee81f fixed this by guarding the second error_setg() with an error_is_set(). Replace this fix by a simpler and safer one: jump right behind the second error_setg().

2014-04-25blockdev: Clean up fragile use of error_is_set()Markus Armbruster1-2/+5
Using error_is_set(ERRP) to find out whether a function failed is either wrong, fragile, or unnecessarily opaque. It's wrong when ERRP may be null, because errors go undetected when it is. It's fragile when proving ERRP non-null involves a non-local argument. Else, it's unnecessarily opaque (see commit 84d18f0). The error_is_set(errp) in internal_snapshot_prepare() is merely fragile, because the caller never passes a null errp argument. Make the code more robust and more obviously correct: receive the error in a local variable, then propagate it through the parameter.

error_is_set(&var) is the same as var != NULL, but it takes whole-program analysis to figure that out. Unnecessarily hard for optimizers, static checkers, and human readers. Commit 84d18f0 dumbed it down to obvious, but a few more have crept in since, and documentation was overlooked. Dumb these down, too.

bdrv_open_backing_file. In 1.7.1 qcow2_create2 reopen the file for flushing without the BDRV_O_NO_BACKING flags. As a consequence the code would recursively open the whole backing chain. These three stack arrays would pile up through the recursion and lead to a coroutine stack overflow. Convert these array to malloced buffers in order to streamline the coroutine footprint. Symptoms where freezes or segfaults on production machines while taking QMP externals snapshots. The overflow disturbed coroutine switching.

Currently it is very easy to crash QEMU by issuing an object-add command using an abstract class or a class that doesn't support TYPE_USER_CREATABLE as parameter. Example: with the following QMP command: (QEMU) object-add qom-type=cpu id=foo QEMU aborts at: ERROR:qom/object.c:335:object_initialize_with_type: assertion failed: (type->abstract == false) This patch moves the check for TYPE_USER_CREATABLE before object_new(), and adds a check to prevent the code from trying to instantiate abstract classes.

2014-04-22qemu-img: Improve error messagesFam Zheng1-28/+46
Previously, when there is a user error in argv parsing, qemu-img prints help text and exits. Add an error_exit function to print a helpful error message and a hint to run 'qemu-img --help' for more information. As a bonus, "qemu-img <cmd> --help" now has a more reasonable exit code 0. In the future the help text should be split by sub command, and only print the information for the specified command.
