The macro REG_RES is to be used to access the syscall return value register in the struct user_regs_struct_t. The macro REG_IP is to be used to access the program counter register in the struct user_regs_struct_t. Signed-off-by:

The macro is introduced to abstract from behavior of breakpoints: they generate different values of the field siginfo.si_code on different architectures. Signed-off-by:

Currenly crtools supports a case when a child shared a fd table with parent. Here is only two interesting things. * Service descriptors should be cloned for each process who shared one fd table. * One task should restore files and other tasks should sleep in this * time. v2: * allocate fdt_lock from shared memory * don't wait a child, if it doesn't share fdtable v3: * don't move ids on the pstree image v4: * save ids in a separate image * save fdinfo per id instead of pid v5: fix alignment of service_fd_id Signed-off-by: -

A few processes can share one fd table. Each process has own set of service file descriptors and a process knows nothing about servic fds of another processes. So if two process share one fd table, close_old_fds will close servic descriptors of another process. Signed-off-by:

fdt shared data contains PID of process, which will restore file descriptors and a futex for synchronization. A process with mimimal pid restores file descriptors. Signed-off-by:

It is read together with pstree items for checking what kind of resources should be shared. Core is too big for reading it in this place. v2: fix check_core Signed-off-by:

A service fd should be created, otherwise get_service_fd returns -1. This patch removes this functionality from other subsystems and allows to clone service descriptors. v2: rename open_service_fd to install_service_fd v3: two patches were merged for bisecting Signed-off-by:

Andrey Vagin authored
It looks like a namespace for service descriptors. It will be used for restoring tasks with shared fd tables. Service descriptors should be own for each process. v2: clone_service_fd doesn't know about sub-systems like log, proc, etc v3: Don't try to find a free name-space. Signed-off-by:

It contains info about the pipe itself, not jut one of its ends. Thus if we want to add more (e.g. -- its size) we'll have to put it there and thus have it always present. Signed-off-by: -

Currently fdinfo dumps for each task, so CR_FD_FDINFO is in cr_fdset. A few tasks can share one fd table and the set of descriptors will be dumped once and a image name will contain files_id instead of pid. In this case CR_FD_FDINFO will go away from cr_fdset. Signed-off-by:

Dump the with "new" prlimit syscall that works on arbitrary pid. Restore is done in restorer _after_ mappings mixup and _before_ caps drop to make it set any max value. The RLIM_INFINITY is handled explicitly to help future 64<->32 bits migration. Signed-off-by: -
