With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant. (Also, defconfigs were not touched to\nkeep the size down.)\n\nThis patch has been generated via the following script:\n\n FILES\u003d$(find * -type f | grep -vE \u0027oprofile|[^K]config\u0027)\n\n sed -i \\\n -e \u0027s/PERF_EVENT_/PERF_RECORD_/g\u0027 \\\n -e \u0027s/PERF_COUNTER/PERF_EVENT/g\u0027 \\\n -e \u0027s/perf_counter/perf_event/g\u0027 \\\n -e \u0027s/nb_counters/nb_events/g\u0027 \\\n -e \u0027s/swcounter/swevent/g\u0027 \\\n -e \u0027s/tpcounter_event/tp_event/g\u0027 \\\n $FILES\n\n for N in $(find . -name perf_counter.[ch]); do\n M\u003d$(echo $N | sed \u0027s/perf_counter/perf_event/g\u0027)\n mv $N $M\n done\n\n FILES\u003d$(find . -name perf_event.*)\n\n sed -i \\\n -e \u0027s/COUNTER_MASK/REG_MASK/g\u0027 \\\n -e \u0027s/COUNTER/EVENT/g\u0027 \\\n -e \u0027s/\\\u003cevent\\\u003e/event_id/g\u0027 \\\n -e \u0027s/counter/event/g\u0027 \\\n -e \u0027s/Counter/Event/g\u0027 \\\n $FILES\n\n... to keep it as correct as possible. This script can also be\nused by anyone who has pending perfcounters patches - it converts\na Linux kernel tree over to the new naming. We tried to time this\nchange to the point in time where the amount of pending patches\nis the smallest: the end of the merge window.\n\nNamespace clashes were fixed up in a preparatory patch - and some\nstylistic fallout will be fixed up in a subsequent patch.\n\n( NOTE: \u0027counters\u0027 are still the proper terminology when we deal\n with hardware registers - and these sed scripts are a bit\n over-eager in renaming them. I\u0027ve undone some of that, but\n in case there\u0027s something left where \u0027counter\u0027 would be\n better than \u0027event\u0027 we can undo that on an individual basis\n instead of touching an otherwise nicely automated patch. )\n\nSuggested-by: Stephane Eranian \u003ceranian@google.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nReviewed-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \"David S.

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": "ade315d83c1d53b3c6b820134cb16601351810fe", "tree": "19d528431ba57ba3f4d7593f3849007ef64d0163", "parents": [ "1e1030dccb1084c8a38976d3656aab1d50d762da" ], "author": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Tue Sep 01 17:45:35 2009 +0900" }, "committer": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Tue Sep 01 17:45:35 2009 +0900" }, "message": "sh: Kill off kgdb\u0027s magical NMI debouncing.\n\nThe kgdb stub has traditionally tied in to the NMI slot, and manually\nhandled debounce.

The signal\nhandler writes the current context and signal return code onto the stack\noverwriting previous contents. During unwinding, libgcc can try to\nrestore registers from the stack and restores corrupted ones. This can\nlead to segmentation, misaligned access and sigbus faults.\n\nFor example, consider the following code:\n\n mov.l r12,@-r15\n mov.l r14,@-r15\n sts.l pr,@-r15\n mov r15,r14\n\n \u003cdo stuff\u003e\n\n mov r14, r15\n lds.l @r15+, pr\n\t\u003c\u003c\u003c SIGNAL HERE\n mov.l @r15+, r14\n mov.l @r15+, r12\n rts\n\nUnwind is aware that pr was pushed to stack in prolog, so tries to\nrestore it.

We probably don\u0027t see this problem often because\nexception handling unwinding in an epilogue only occurs due to a pthread\ncancel signal. Also the kernel signal stack handler alignment of 8 bytes\ncould hide the occurance of this problem sometimes as the stack may not\nbe trampled at a particular required word.\n\nThis is not guaranteed to always work.

Runtime\nsuspend is however allowed from interrupt context as\nlong as the synchronous functions are avoided.\n\n[ updated for v17 -- PFM. ]\n\nSigned-off-by: Magnus Damm \u003cdamm@igel.co.jp\u003e\nSigned-off-by: Paul Mundt \u003clethal@linux-sh.org\u003e\n" }, { "commit": "4f896ffca2b72f4b719746e7fbb0b623252e6ac9", "tree": "f77ef49e1111c1efd4eec1ae305c8bbf746f1cdf", "parents": [ "fa9d3b4da55fc8949efc2b4220d93f188fbcebd6" ], "author": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Sat Aug 22 19:03:25 2009 +0900" }, "committer": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Sat Aug 22 19:03:25 2009 +0900" }, "message": "sh: unwinder: cacheline align slab cache objects.\n\nThe CIE and FDE structs are big enough and accessed regularly enough in\ncertain configurations to make cacheline alignment useful.\n\nSigned-off-by: Paul Mundt \u003clethal@linux-sh.org\u003e\n" }, { "commit": "fa9d3b4da55fc8949efc2b4220d93f188fbcebd6", "tree": "ead3e046b7e6e101d1d27db36116c52405d43c36", "parents": [ "c01f0f1a4a96eb3acc5850e18cc43f24366966d0", "74db2479c1fecefd0a190f282f28f00565309807" ], "author": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Sat Aug 22 05:37:14 2009 +0900" }, "committer": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Sat Aug 22 05:37:14 2009 +0900" }, "message": "Merge branch \u0027sh/dwarf-unwinder\u0027\n\nConflicts:\n\tarch/sh/kernel/cpu/sh3/entry.S\n" }, { "commit": "e115f2c17cbceee93b34d787a7a4a867fc73e7b4", "tree": "6ee0f20dcb5eca29793d68e97242c5e483c24cfc", "parents": [ "c153a58e715e16ffcd6c4b3da7fc6b4a556bf917" ], "author": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Sat Aug 22 05:28:25 2009 +0900" }, "committer": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Sat Aug 22 05:28:25 2009 +0900" }, "message": "sh: unwinder: Use a special bug flag for unwinder traps.\n\nThis simplifies the unwinder trap handling, dropping the use of the\nspecial trapa vector and simply piggybacking on top of the BUG support.

It turns out that the bogus cfa_offset value\ncame from interpreting .cfi_escape pseudo-ops (those used by the GNU\nextensions) as CFA_DW_def_cfa ops.\n\nSigned-off-by: Matt Fleming \u003cmatt@console-pimps.org\u003e\n" }, { "commit": "b955873bf530ee4b80e6c8b734521ad07cbaed7e", "tree": "44367dd882fc8851f32285ddcdcb3f62892df99d", "parents": [ "38f9ddf44150c1a213b41726384d055f7c35ec4f" ], "author": { "name": "Matt Fleming", "email": "matt@console-pimps.org", "time": "Sat Aug 15 23:10:57 2009 +0100" }, "committer": { "name": "Matt Fleming", "email": "matt@console-pimps.org", "time": "Sun Aug 16 12:48:53 2009 +0100" }, "message": "sh: Try again at getting the initial return address for an unwind\n\nThe previous hack for calculating the return address for the first frame\nwe unwind (dwarf_unwinder_dump) didn\u0027t always work.
