Now kdump returns\n APs to SAL before processing dump, but the kernel might receive INIT at\n that point in time.

If a cpu is spinning in SAL,\n the cpu is in BOOT_RENDEZ loop, as same as offlined cpu.\n In theory if an INIT is asserted there, cpus in the BOOT_RENDEZ loop\n should not invoke OS_INIT on it.

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": "384be2b18a5f9475eab9ca2bdfa95cc1a04ef59c", "tree": "04c93f391a1b65c8bf8d7ba8643c07d26c26590a", "parents": [ "a76761b621bcd8336065c4fe3a74f046858bc34c", "142d44b0dd6741a64a7bdbe029110e7c1dcf1d23" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Fri Aug 14 14:41:02 2009 +0900" }, "committer": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Fri Aug 14 14:45:31 2009 +0900" }, "message": "Merge branch \u0027percpu-for-linus\u0027 into percpu-for-next\n\nConflicts:\n\tarch/sparc/kernel/smp_64.c\n\tarch/x86/kernel/cpu/perf_counter.c\n\tarch/x86/kernel/setup_percpu.c\n\tdrivers/cpufreq/cpufreq_ondemand.c\n\tmm/percpu.c\n\nConflicts in core and arch percpu codes are mostly from commit\ned78e1e078dd44249f88b1dd8c76dafb39567161 which substituted many\nnum_possible_cpus() with nr_cpu_ids.

#12454. Someone can lookup entry with NULL\n-\u003eowner, thus not pinning enything, and release it later resulting\nin module refcount underflow.\n\nWe can keep -\u003eowner and supply it at registration time like -\u003eproc_fops\nand -\u003edata.\n\nBut this leaves -\u003eowner as easy-manipulative field (just one C assignment)\nand somebody will forget to unpin previous/pin current module when\nswitching -\u003eowner. -\u003eproc_fops is declared as \"const\" which should give\nsome thoughts.\n\n-\u003eread_proc/-\u003ewrite_proc were just fixed to not require -\u003eowner for\nprotection.\n\nrmmod\u0027ed directories will be empty and return \".\" and \"..\" -- no harm.\nAnd directories with tricky enough readdir and lookup shouldn\u0027t be modular.\nWe definitely don\u0027t want such modular code.\n\nRemoving -\u003eowner will also make PDE smaller.\n\nSo, let\u0027s nuke it.\n\nKudos to Jeff Layton for reminding about this, let\u0027s say, oversight.\n\nhttp://bugzilla.kernel.org/show_bug.cgi?id\u003d12454\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\n" }, { "commit": "b0d44c0dbbd52effb731b1c0af9afd56215c48de",

__kernel_syscall_via_epc.\n\nMove down __kernel_syscall_via_epc to the end of the page.\nWe want to paravirtualize only __kernel_syscall_via_epc because\nit includes privileged instructions. Its paravirtualization increases\nits symbols size.\n\nOn the other hand, each paravirtualized gate must have e symbols of\nsame value and size to native\u0027s because the page is mapped to GATE_ADDR\nand GATE_ADDR + PERCPU_PAGE_SIZE and vmlinux is linked to those symbols.\nLater to have the same symbol size, we pads NOPs at the end of\n__kernel_syscall_via_epc. Move it after other functions to keep\nsymbols of other functions have same values and sizes.\n\nSigned-off-by: Isaku Yamahata \u003cyamahata@valinux.co.jp\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "b937dd76d07f2347684d6cc1e1ec4e2746417357", "tree": "be711211f1b83d8cebff60b01bbbd1e80e609295", "parents": [ "e4ff5b8f545811008123dd9556a51d814f562fcf" ], "author": { "name": "Isaku Yamahata", "email": "yamahata@valinux.co.jp", "time": "Wed Mar 04 21:05:43 2009 +0900" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Thu Mar 26 10:51:12 2009 -0700" }, "message": "ia64/pv_ops/xen: define xen specific gate page.\n\ndefine xen specific gate page.\nAt this phase bits in the gate page is same to native.\nAt the next phase, it will be paravirtualized.\n\nSigned-off-by: Isaku Yamahata \u003cyamahata@valinux.co.jp\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "e4ff5b8f545811008123dd9556a51d814f562fcf", "tree": "2c308a3b1cc002f0d345ed64dd94a395678543bb", "parents": [ "1aec1c558a797512e922581b21a178a05438bfc9" ], "author": { "name": "Isaku Yamahata", "email": "yamahata@valinux.co.jp", "time": "Wed Mar 04 21:05:42 2009 +0900" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Thu Mar 26 10:51:02 2009 -0700" }, "message": "ia64/pv_ops: gate page paravirtualization.\n\nparavirtualize gate page by allowing each pv_ops instances\nto define its own gate page.\n\nSigned-off-by: Isaku Yamahata \u003cyamahata@valinux.co.jp\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "f927da178671a824cf6c530f0623544206387e57", "tree": "fb9178ff79bfd9ee3b396ff20018eacbfb222d47", "parents": [ "496203b15b7249599712525c2b6aafe231b4628d" ], "author": { "name": "Isaku Yamahata", "email": "yamahata@valinux.co.jp", "time": "Wed Mar 04 21:05:40 2009 +0900" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Thu Mar 26 10:50:42 2009 -0700" }, "message": "ia64/pv_ops/pv_time_ops: add sched_clock hook.\n\nadd sched_clock() hook to paravirtualize sched_clock().\nia64 sched_clock() is based on ar.itc which isn\u0027t stable\non virtualized environment because vcpu may move around on\npcpus.
