If a master point has sid, it doesn't mean, that all slave points will have sid. Look at tty03 for example: PID SID TT COMMAND 26748 26748 ? tty03 26749 26749 pts/2 \_ tty03 26750 26750 ? \_ tty03 The second process has not a file descriptor for the ctl tty, but this tty is opened in tty03. v2: If a slave point with sid has not a master point, the option --shell-job must be set and sid isn't restored for such terminals.

The system call open can add O_LARGEFILE. A point is reopend for unsharing a file descriptor. So here are two types of points. One is returned by pipe() and all other ones are got via opening /proc/PID/fd. Currently I know only one difference between these types, it's O_LARGEFILE. Signed-off-by:

mnt_entry::fstype is a part of image ABI, thus we need to provide some "common" encoding outside tools would know about this field encoding. Thus we instorduce fstype enum in .proto file and use it in source code as well. Signed-off-by:

The page server is a process, that is about to get pages over the network and put them into pagemap- + pages- images. Right now what it does is simply get the data and puts it into the image files. When we have dirty set tracking in the kernel the page server will have to collect "page changes" and properly integrate them into images. Running crtools with page server is like this: dst_node# crtools page-server --port <port> -D dump/ ... src_node# crtools dump -t <pid> --page-server --address <dst_node> --port <port> -D dump/ ... After this images from dst_node/dump/ and src_node/dump/ should be put into one place and tasks can be restored out of it. Signed-off-by: -

Since now we drain pages out of parasite, we can invent any format for page dumps. Let is be ... prorobuf one! :) Another thing to keep in mind, is that we're about to use splices and implement iterative migration, so it's better to have actual pages be page-aligned in the image. And -- backward compatibility. That said the new format is: 1. pagemap-... file which contains a header (currently with a ID of the image with pages, see below) and an array of <nr_pages:vaddr> pairs. The first value means "how many pages to take from the file with pages (see below)" and the second -- where in the task address space to put them. Simple. 2. pages-... file which containes only pages one by one (thus aligned as we want). This patch breaks backward compatibility (old images with pages wil be restored and then crash). Need to do it before v0.5 release. Signed-off-by:

Generate random data only for buffers with sizes less than FAST_SIZE If a size of buffer is more that FAST_SIZE, the first FAST_SIZE bytes are filled by random generator and then this chunk is used as pattern for all other chunks.
