When a kernel didn't show vma flags, we set MAP_GROWSDOWN for stack vmas, but it's not reliable. E.g. thread stacks are mapped without MAP_GROWSDOWN. Signed-off-by:

The size of vma can be changed after parsing flags. For example we need to add a guard page for vma with MAP_GROWSDOWN. Signed-off-by:

It's being reported that some systems (as Ubuntu 13.04) already have struct tcp_repair_opt definition in their system headers. | sk-tcp.c:25:8: error: redefinition of struct tcp_repair_opt | sk-tcp.c:31:2: error: redeclaration of enumerator TCP_NO_QUEUE So add a facility for compile time testing for reported entities to be present on a system. For this we generate include/config.h where all tested entries will lay and source code need to include it only in places where really needed. Reported-by:

Some features need to be tested on the system where the project is compiled, so instead of drowning into autoconf hell lets try to handle all this with make facility. Signed-off-by:

Just open /proc/self/ns/net and check if it remains the same on restore. Signed-off-by:
-
Pavel Emelyanov authored
Based on work done by Cyrill Corcunov (many thanks for that). In this commit we implement c/r for files which have opened /proc/$pid/ns/$ids entries. The idea is rather simple one Checkpoint ========== - Check if the file name is the one of known to be ns ref - If match then write protobuf entry Restore ======= - Read all ns entries from the image - When criu tries to open one we lookup over process tree to figure out which PID should be used in path and then just open it Signed-off-by:

This will be needed for fast parsing of procfs ns references. [ xemul: Add user_ns_desc here ] Signed-off-by:

Cyrill Gorcunov authored
To be able to dump procfs namespace entries we will need to analyze the link name first and then figure out if the file referred indeed a procfs entry or it's plain regular file. This means we read link early, and to escape double reading of same link, once we read it we remember it in fd_parms structure which we pass to dump_one_reg_file. Still the dump_one_reg_file is not solely used from inside of dump_one_file, but from a number of other places (fifo, special files) where fd_parms is filled only partially and fill_fd_params is not even called. Thus dump_one_reg_file must be ready for such scenario and read the link name by own if the caller has not provided one. To achieve all this we do - extend fd_parms structure to have a reference on a new fd_link structure, thus if caller already read the link name it might assign the reference and call for dump_one_reg_file - tune up dump_one_reg_file to fill own copy of fd_link structure if the caller has not provied one [ xemul: Added const to fill_fdlink arg ] Signed-off-by:

struct fd_parms is reused for two calls, so don't forget to initialize it before dump_one_reg_file call. Signed-off-by:

All this sits under config option, so we shouldn't try to read/write them in this case. What to do if they are in different on/off state on src/dst kernels is an open question :\ Signed-off-by: -

The soft-dirty API has changed slightly -- now the bit in question _is_ in pagemap file (not pagemap2) but to see it we have to reset soft-dirty for anyone first. Teach the kerndat soft-dirty checker this fact. The actual pagemap reading code already knows select pagemap/pagemap2 file itself. Signed-off-by: -
