[Qemu-devel] [PATCH 0/2] linux-user: fix some msgrcv edge cases |

These patches fix a couple of issues with handling edge cases
in our linux-user msgrcv implementation:
* we weren't dealing with negative msgsz correctly (should fail EINVAL)
* we were using g_malloc() rather than g_try_malloc() for an allocatino
whose size is controlled by the guest
(Both these were already handled correctly for msgsnd.)
This fixes a hang in the Linux Test Project msgrcv03 test case.

linux-user: Use g_try_malloc() in do_msgrcv()
