welcome Performance Events!\n\nIn the past few months the perfcounters subsystem has grown out its\ninitial role of counting hardware events, and has become (and is\nbecoming) a much broader generic event enumeration, reporting, logging,\nmonitoring, analysis facility.\n\nNaming its core object \u0027perf_counter\u0027 and naming the subsystem\n\u0027perfcounters\u0027 has become more and more of a misnomer. 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.

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": "e7a088f935180b90cfe6ab0aaae8a556f46885fe", "tree": "3456eea4f37e1dfa590fed0cb24090c7ebbf29f5", "parents": [ "75d9e34698540e96b422293e1d76ab02cc7faefb" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Tue Sep 01 17:54:07 2009 -0700" }, "committer": { "name": "David S.

We can do this because bit 41 indicates\n\"I/O space\" and thus covers non-memory ranges.\n\nThe result of this is that:\n\n1) kpte_linear_bitmap shrinks from 2K to 1K in size\n\n2) we need 64K more for the valid address bitmap\n\nWe can\u0027t let the valid address bitmap be dynamically allocated\nonce we start using it to validate TLB misses, otherwise we have\ncrazy issues to deal with wrt. recursive TLB misses and such.\n\nIf we\u0027re in a TLB miss it could be the deepest trap level that\u0027s legal\ninside of the cpu.

It mostly changes how information is passed among\ninitialization functions and makes room for more flexibility.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: David Miller \u003cdavem@davemloft.net\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.

Thus, currently 32-bit tasks on 64-bit platforms\ncannot properly receive events and fail with all kinds of\nstrange problems, for instance wpa_supplicant never notices\ndisassociations, due to the way the 64-bit event looks (to a\n32-bit process), the fact that the address is all zeroes is\nlost, it thinks instead it is 00:00:00:00:01:00.\n\nThe same problem existed with the ioctls, until David Miller\nfixed those some time ago in an heroic effort.\n\nA different problem caused by this is that we cannot send the\nASSOCREQIE/ASSOCRESPIE events because sending them causes a\n32-bit wpa_supplicant on a 64-bit system to overwrite its\ninternal information, which is worse than it not getting the\ninformation at all -- so we currently resort to sending a\ncustom string event that it then parses. This, however, has a\nsevere size limitation we are frequently hitting with modern\naccess points; this limitation would can be lifted after this\npatch by sending the correct binary, not custom, event.\n\nA similar problem apparently happens for some other netlink\nusers on x86_64 with 32-bit tasks due to the alignment for\n64-bit quantities.\n\nIn order to fix these problems, I have implemented a way to\nsend compat messages to tasks. When sending an event, we send\nthe non-compat event data together with a compat event data in\nskb_shinfo(main_skb)-\u003efrag_list. Then, when the event is read\nfrom the socket, the netlink code makes sure to pass out only\nthe skb that is compatible with the task. This approach was\nsuggested by David Miller, my original approach required\nalways sending two skbs but that had various small problems.\n\nTo determine whether compat is needed or not, I have used the\nMSG_CMSG_COMPAT flag, and adjusted the call path for recv and\nrecvfrom to include it, even if those calls do not have a cmsg\nparameter.\n\nI have not solved one small part of the problem, and I don\u0027t\nthink it is necessary to: if a 32-bit application uses read()\nrather than any form of recvmsg() it will still get the wrong\n(64-bit) event. However, neither do applications actually do\nthis, nor would it be a regression.\n\nSigned-off-by: Johannes Berg \u003cjohannes@sipsolutions.net\u003e\nSigned-off-by: David S.
