This fixes a bug on s390, where we allow both config options\nHIBERNATION and MEMORY_HOTPLUG, so that we also have a ZONE_MOVABLE\nhere. We only allow hibernation if no memory hotplug operation was\nperformed, so in fact both features can only be used exclusively, but\nthis way we don\u0027t need 2 differently configured (distribution) kernels.\n\nIf we have an unpopulated ZONE_MOVABLE, we allow hibernation but run\ninto a BUG_ON() in memory_bm_test/set/clear_bit() because hibernation\ncode iterates through all zones, not only the populated zones, in\nseveral places. For example, swsusp_free() does for_each_zone() and\nthen checks for pfn_valid(), which is true even if the zone is not\npopulated, resulting in a BUG_ON() later because the pfn cannot be\nfound in the memory bitmap.\n\nReplacing all occurences of for_each_zone() in hibernation code with\nfor_each_populated_zone() would fix this issue.\n\n[rjw: Rebased on top of linux-next hibernation patches.]\n\nSigned-off-by: Gerald Schaefer \u003cgerald.schaefer@de.ibm.com\u003e\nAcked-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Rafael J.

process\u0027s session keyring onto its parent. This\nreplaces the parent\u0027s session keyring. Because the COW credential code does\nnot permit one process to change another process\u0027s credentials directly, the\nchange is deferred until userspace next starts executing again. Normally this\nwill be after a wait*() syscall.\n\nTo support this, three new security hooks have been provided:\ncred_alloc_blank() to allocate unset security creds, cred_transfer() to fill in\nthe blank security creds and key_session_to_parent() - which asks the LSM if\nthe process may replace its parent\u0027s session keyring.\n\nThe replacement may only happen if the process has the same ownership details\nas its parent, and the process has LINK permission on the session keyring, and\nthe session keyring is owned by the process, and the LSM permits it.\n\nNote that this requires alteration to each architecture\u0027s notify_resume path.\nThis has been done for all arches barring blackfin, m68k* and xtensa, all of\nwhich need assembly alteration to support TIF_NOTIFY_RESUME. This allows the\nreplacement to be performed at the point the parent process resumes userspace\nexecution.\n\nThis allows the userspace AFS pioctl emulation to fully emulate newpag() and\nthe VIOCSETTOK and VIOCSETTOK2 pioctls, all of which require the ability to\nalter the parent process\u0027s PAG membership. However, since kAFS doesn\u0027t use\nPAGs per se, but rather dumps the keys into the session keyring, the session\nkeyring of the parent must be replaced if, for example, VIOCSETTOK is passed\nthe newpag flag.\n\nThis can be tested with the following program:\n\n\t#include \u003cstdio.h\u003e\n\t#include \u003cstdlib.h\u003e\n\t#include \u003ckeyutils.h\u003e\n\n\t#define KEYCTL_SESSION_TO_PARENT\t18\n\n\t#define OSERROR(X, S) do { if ((long)(X) \u003d\u003d -1) { perror(S); exit(1); } } while(0)\n\n\tint main(int argc, char **argv)\n\t{\n\t\tkey_serial_t keyring, key;\n\t\tlong ret;\n\n\t\tkeyring \u003d keyctl_join_session_keyring(argv[1]);\n\t\tOSERROR(keyring, \"keyctl_join_session_keyring\");\n\n\t\tkey \u003d add_key(\"user\", \"a\", \"b\", 1, keyring);\n\t\tOSERROR(key, \"add_key\");\n\n\t\tret \u003d keyctl(KEYCTL_SESSION_TO_PARENT);\n\t\tOSERROR(ret, \"KEYCTL_SESSION_TO_PARENT\");\n\n\t\treturn 0;\n\t}\n\nCompiled and linked with -lkeyutils, you should see something like:\n\n\t[dhowells@andromeda ~]$ keyctl show\n\tSession Keyring\n\t -3 --alswrv 4043 4043 keyring: _ses\n\t355907932 --alswrv 4043 -1 \\_ keyring: _uid.4043\n\t[dhowells@andromeda ~]$ /tmp/newpag\n\t[dhowells@andromeda ~]$ keyctl show\n\tSession Keyring\n\t -3 --alswrv 4043 4043 keyring: _ses\n\t1055658746 --alswrv 4043 4043 \\_ user: a\n\t[dhowells@andromeda ~]$ /tmp/newpag hello\n\t[dhowells@andromeda ~]$ keyctl show\n\tSession Keyring\n\t -3 --alswrv 4043 4043 keyring: hello\n\t340417692 --alswrv 4043 4043 \\_ user: a\n\nWhere the test program creates a new session keyring, sticks a user key named\n\u0027a\u0027 into it and then installs it on its parent.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\n" }, { "commit": "e0e817392b9acf2c98d3be80c233dddb1b52003d", "tree": "ee680c020039313c9f9c40ab3542bb30a7363381", "parents": [ "ed6d76e4c32de0c2ad5f1d572b948ef49e465176" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Wed Sep 02 09:13:40 2009 +0100" }, "committer": { "name": "James Morris", "email": "jmorris@namei.org", "time": "Wed Sep 02 21:29:01 2009 +1000" }, "message": "CRED: Add some configurable debugging [try #6]\n\nAdd a config option (CONFIG_DEBUG_CREDENTIALS) to turn on some debug checking\nfor credential management.
