The modes are\n\n0 - (default) - traditional behaviour. Any process which has changed\n privilege levels or is execute only will not be dumped\n\n1 - (debug) - all processes dump core when possible. The core dump is\n owned by the current user and no security is applied. This is intended\n for system debugging situations only. Ptrace is unchecked.\n\n2 - (suidsafe) - any binary which normally would not be dumped is dumped\n readable by root only. This allows the end user to remove such a dump but\n not access it directly. For security reasons core dumps in this mode will\n not overwrite one another or other files. This mode is appropriate when\n adminstrators are attempting to debug problems in a normal environment.\n\n(akpm:\n\n\u003e \u003e +EXPORT_SYMBOL(suid_dumpable);\n\u003e\n\u003e EXPORT_SYMBOL_GPL?\n\nNo problem to me.\n\n\u003e \u003e \tif (current-\u003eeuid \u003d\u003d current-\u003euid \u0026\u0026 current-\u003eegid \u003d\u003d current-\u003egid)\n\u003e \u003e \t\tcurrent-\u003emm-\u003edumpable \u003d 1;\n\u003e\n\u003e Should this be SUID_DUMP_USER?\n\nActually the feedback I had from last time was that the SUID_ defines\nshould go because its clearer to follow the numbers.
