Currently the buffer size is 4096. It always works because we use hosts where PAGE_SIZE is 4096. PowerPC64 has a bigger PAGE_SIZE. Here is a comment from the kernel code. /* * skb should fit one page. This choice is good for headerless malloc. * But we should limit to 8K so that userspace does not have to * use enormous buffer sizes on recvmsg() calls just to avoid * MSG_TRUNC when PAGE_SIZE is very large. */ We set the buffer size to 16384, because it's the max length of recvmsg() for this case. We will need less iterations to collect all data, so the perfomance should be better. Signed-off-by:

1) Deleted bindmount for files should be restored by creating temp file. The kernel doesn't permit to mix bindmount in terms of file/dir relationship: either both source and target should be files or directories. Thus we can call stat on the target and figure out what kind of source we had. 2) Even for deleted entries better to use permissions from the target's stat call, this makes result close to how would it look if program hadn't been checkpointed.

The commit 69d008d5 ("Use run-time page_size() for mremap") introduces the use of dynamic page size in rst-malloc.c. The commit also add the include of unistd.h in arch/aarch64/include/asm/page.h to allow the build to succeed on this architecture. Since ppc64 is also using the same way to deal with page size, the same include is required in arch/ppc64/include/asm/page.h Signed-off-by:

You can see two equal inode numbers with differen devices and it was a reason why the test failed. 4: C: 12491/12495/12496 4: c: 1: POSIX ADVISORY WRITE 0 fc:03:12468 0 EOF 4: c: 2: POSIX ADVISORY READ 0 fc:03:12421 0 EOF 4: c: 3: POSIX ADVISORY WRITE 0 00:14:16285 0 EOF 4: c: 4: FLOCK MSNFS READ 4 fc:03:12496 0 EOF 4: c: 5: FLOCK ADVISORY WRITE 4 fc:03:12495 0 EOF 4: c: 6: FLOCK ADVISORY READ 4 fc:03:12491 0 EOF 4: c: 7: POSIX ADVISORY WRITE 0 00:14:16280 0 EOF 4: c: 8: POSIX ADVISORY WRITE 0 00:14:12677 0 EOF 4: c: 9: FLOCK ADVISORY WRITE 0 00:14:12520 0 EOF 4: c: 10: FLOCK ADVISORY WRITE 0 00:14:12495 0 EOF Signed-off-by:

To handle deleted bindmounts we simply create the former directory bindmount lived at, mount the target and remove the directory back. For this sake we add @deleted entry into the image. Signed-off-by:

It's quite unclean while this structure lives in proc_parse.h, which only have to fill this structure on procfs read, but real handling is inside mount.c. Move it as appropriate. Same time ext_mount structure should be moved into a header as well with sane @list name used instead of @l. Signed-off-by:
