We (may) have 3 types of namespace objects in criu -- criu's one, root task's one and others. All of them sometimes make sense and we differentiate them in a weird way -- by checking the ns->pid field against getpid() or by comparing with root_item's. The proposal is to mark ns_id objects explicitly with type field. Signed-off-by:Pavel Emelyanov <xemul@parallels.com>

We'll use this size in the next patch to avoid having to do some dynamic allocation. v2: call it MAX_UNSFD_MSG_SIZE instead v3: fix all uses of MAX_MSG_SIZE :) Signed-off-by:

Currently we have only one common flag. It is MS_READONLY and it's interpreted as a super block flag to not change old behaviour. v2: add a comment Signed-off-by:

Andrey Vagin authored
They both can container the MS_READONLY flag. And in one case it will be read-only bind-mount and in another case it will be read-only super-block. v2: set mnt and sb for one call of mount() when it's posiable v3: return a comment which was deleted by mistake v4: Fix the sentense about restoring mnt flags Signed-off-by:

Some flags have known text description, e.g. flags on a file or flags on vma. Add ability to show these flags in decoded form (and encode them back into binary). Signed-off-by: -

"criu cpuinfo [dump | check]" can't be used through the command line as this validation kicks in. Other commands will fail due to required arguments so I believe it's not necessary anymore. Signed-off-by:

Some controllers can be disabled in kernel options. In this case they are shown in /proc/cgroups, but they could not be mounted. All enabled controllers can be collected from /proc/self/cgroup. https://github.com/xemul/criu/issues/28 v2: ',' is used to separate controllers Cc: Tycho Andersen <tycho.andersen@canonical.com> Reported-by:

The commit ba743509 which introduces support for Altivec and VSX support was breaking the checkpoint --leave-running. The root cause is that the address of the Altivec and VSX registers in the signal frame should be computed for the stack in the context of the checkpointed process. This patch fixes this issue through the sigreturn_prep_fpu_frame which is designed to update the signal frame based on the remote address.

There were multiple copy of the same code spread over the different architectures handling the vDSO. This patch is merging the duplicated code in arch/*/vdso-pie.c and arch/*/include/asm/vdso.h in the common files and let only the architecture specific part in the arch/*/* files. The file are now organized this way: include/asm-generic/vdso.h contains basic definition which could be overwritten by architectures. arch/*/include/asm/vdso.h contains per architecture definitions. It may includes include/asm-generic/vdso.h pie/util-vdso.c include/util-vdso.h These files contains code and definitions common to both criu and the parasite code. The file include/util-vdso.h includes arch/*/include/asm/vdso.h. pie/parsite-vdso.c include/parasite-vdso.h contains code and definition specific to the parasite code handling the vDSO. The file include/parasite-vdso.h includes include/util-vdso.h. arch/*/vdso-pie.c contains the architecture specific code installing the vDSO trampoline. vdso.c include/vdso.h contains code and definition specific to the criu code handling the vDSO. The file include/vdso.h includes include/util-vdso.h. CC: Christopher Covington <cov@codeaurora.org> CC: Pavel Emelyanov <xemul@parallels.com> Signed-off-by:

Merge arch/*/vdso.c files in vdso.c. The merge has been done by copying arch/x86/vdso.c in vdso.c since it contains patch a67e9f7b ("vdso: don't play with a function exit code"). The commit f9ae6d9d ("Replace remaining hard-coded TASK_SIZE use") pushed in the aarch64 has been replicated since it should be cross platform.

In commit 664659a0 we defined max possible values for TCP queues but on low memory machines (or on machinese whith custom limits set via sysctl) this trick doesn't work well all the time. We have to fetch the allowed values from /proc/sys/net/ipv4/tcp_[wmem|rmem] which might be simply missing on the environment we run. So lets stick with really small values here got from kernel source code so instead of failing we would be able to restore in a bit "slower" than usual. Signed-off-by:
