[lxc-devel] [PATCH] Ensure that mmap()ed memory is \0-terminated (v3)

Use pwrite() to write terminating \0-byte This allows us to use standard string handling functions and we can avoid using the GNU-extension memmem(). This simplifies removing the container from the lxc_snapshots file. Wrap strstr() in a while loop to remove duplicate entries. Signed-off-by:

[lxc-devel] [PATCH] New approach to remove container entry from lxc_snapshots (v3)

I want to avoid having to use the GNU-extension memmem() when removing the container entry. As mmap() does not guarantee us a \0-terminated string we pwrite() a single terminating \0-byte after the end of the file and the mmap() the file. The terminating \0-byte will then be removed when we

[lxc-devel] [PATCH] Add remove_snapshots_entry()

When creating ephemeral containers that have the option lxc.ephemeral = 1 set in their config, they will be destroyed on shutdown. As they are simple overlay clones of an existing container they should be registered in the lxc_snapshots file of the original container to stay consistent and adhere
