Previously the save_external_coredump function returned a file descriptor corresponding to the dumped file. This descriptor was used for two different purposes by calling code: a) access to the raw core dump data; b) testing candidate files (via inode comparisons) while vacuuming to protect the current core dump from vacuuming. The descriptor returned always corresponded to a file containing the raw core dump data. However if compresson was used and the core dump was compressed then the descriptor returned did not correspond to the file that would eventually be left on disk (ie the compressed file). Thus the file was never protected by vacuuming. When disk space was low all core dumps including the current one would be vacuumed and the corresponding log message referred to a file that no longer existed. This resulted in the following error message from coredumpctl if the missing core dump was requested: Cannot retrieve coredump from journal nor disk. Failed to retrieve core: No such file or directory save_external_coredump now returns two descriptors, one to be used for inode comparisons to prevent overzealous vacuuming and one to be used for raw data access. When compression is not used the returned inode comparison descriptor will be invalid, indicating that the raw data access descriptor should be used for inode comparisons as well. Corresponding use of save_external_coredump and the returned descriptors also updated. |
