Currently only addresses are compared. It's obviously not enough. * First of all the parent vma must be private. * Both vma-s must have the identical set of MAP_GROWSDOWN and MAP_FILES flags. * Both vma-s must be linked to the same file. https://bugzilla.openvz.org/show_bug.cgi?id=2824Signed-off-by:

shmid contains a file id for file mappings. It's required to determine, which VMA-s are cowed. The parent maps a VMA and saves premmaped address. Then child trys to determing, which VMA-s must be inhereted from parent, for that it compares addresses, flags and file id. We don't want to transfer vma_area-s in restorer, so when a VMA entry is copied in restorer memory, the premmaped address is save in shmid. Signed-off-by:

Both fopen_proc() and opendir_proc() are calling open_proc(). If open_proc() fails, it prints an error message. Before this patch, a second error message was printed due to missing brackets. This second message is a bit more specific (it tells the exact file/dir we failed to open) but it is redundant, because more generic error was already printed by open_proc(). It is also can be misleading because for the second message we reuse the same errno while we should not. So, let's remove this second error message print by using brackets. Alternatively, we could leave this as is (just fixing indentation) and let two errors be printed -- there is nothing wrong with that, but I think in this case less messages is better. This is a fix to commit 5661d806. Signed-off-by:

After set of patches which add --work-dir option we have an issue: logs are created relatively to current dir and not relatively to images dir(which is work dir, when --work-dir is not given). To solve this lets init log after chdir(work_dir) Signed-off-by:

All data in a write buffer can be divided on two parts sent but not yet acknowledged data and unsent data. Currently the boundary between sent and unsent data is not dumped and all the data are restored as if they have already been sent. This methode can provoke long delays in tcp connection, because a kernel can wait before retransmitting data. https://bugzilla.openvz.org/show_bug.cgi?id=2808 The TCP stack must know which data have been sent, because acknowledgment can be received for them. These data must be restored in repair mode. The second part of data have never been sent out, so they can be restored without any tricks. These data can be sent into socket as usual. For restoring unsent data the repair mode is disabled for socket, but it is enabled back after restoring data. It will be disabled after unlocking network. In this case window probe is sent, which is required for waknge the connection. This patch fixes long delays in tcp connections after dumping and restoring. Thanks Pavel for the idea of disabling repair mode for restoring unsent data. https://bugzilla.openvz.org/show_bug.cgi?id=2808Signed-off-by:

At moment we generate protobuf dependencies having in mind that protobuf/ directory is _always_ in the source code root. This may change one day in future so better to be on safe side and escape slashes immediately. I meet this problem when been needed to build protobuf builtin in $(root)/src/protobuf directory.
