[libvirt] [PATCHv3 0/6] Fix memory corruption/crash in the connection close callback

This series fixes the crash resulting from a race condition in the connection close callback. To observe the crash apply the first patch only. To verify that the patchset fixes the crash please apply all but 2/6 and verify using virsh. 2/6 fixes the crash in a redundant way in case the close callback is used. In the case it isn't 2/6 itself can't fix the issue. For a better explanation of this problem please see the description in 6/6. Peter Krempa (4): DO NOT APPLY UPSTREAM: Close callback race corruption crash reproducer. virsh: Move cmdConnect from virsh-host.c to virsh.c virsh: Register and unregister the close callback also in cmdConnect rpc: Fix connection close callback race condition and memory corruption/crash Viktor Mihajlovski (2): libvirt: Increase connection reference count for callbacks virsh: Unregister the connection close notifier upon termination src/datatypes.c | 55 ++++++++++++++++++++---- src/datatypes.h | 22 +++++++--- src/libvirt.c | 30 ++++++++----- src/remote/remote_driver.c | 62 ++++++++++++++++----------- src/rpc/virnetclient.c | 9 +++- tools/virsh-host.c | 67 ----------------------------- tools/virsh.c | 102 ++++++++++++++++++++++++++++++++++++++++++--- 7 files changed, 225 insertions(+), 122 deletions(-) -- 1.8.1.5
