git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull perf updates from Ingo Molnar: "As a first remark I'd like to note that the way to build perf tooling has been simplified and sped up, in the future it should be enough for you to build perf via: cd tools/perf/ make install (ie without the -j option.) The build system will figure out the number of CPUs and will do a parallel build+install. The various build system inefficiencies and breakages Linus reported against the v3.12 pull request should now be resolved - please (re-)report any remaining annoyances or bugs. Main changes on the perf kernel side: * Performance optimizations: . perf ring-buffer code optimizations, by Peter Zijlstra . perf ring-buffer code optimizations, by Oleg Nesterov . x86 NMI call-stack processing optimizations, by Peter Zijlstra . perf context-switch optimizations, by Peter Zijlstra . perf sampling speedups, by Peter Zijlstra . x86 Intel PEBS processing speedups, by Peter Zijlstra * Enhanced hardware support: . for Intel Ivy Bridge-EP uncore PMUs, by Zheng Yan . for Haswell transactions, by Andi Kleen, Peter Zijlstra * Core perf events code enhancements and fixes by Oleg Nesterov: . for uprobes, if fork() is called with pending ret-probes . for uprobes platform support code * New ABI details by Andi Kleen: . Report x86 Haswell TSX transaction abort cost as weight Main changes on the perf tooling side (some of these tooling changes utilize the above kernel side changes): * 'perf report/top' enhancements: . Convert callchain children list to rbtree, greatly reducing the time taken for callchain processing, from Namhyung Kim. . Add new COMM infrastructure, further improving histogram processing, from Frédéric Weisbecker, one fix from Namhyung Kim. . Add /proc/kcore based live-annotation improvements, including build-id cache support, multi map 'call' instruction navigation fixes, kcore address validation, objdump workarounds. From Adrian Hunter. . Show progress on histogram collapsing, that can take a long time, from Namhyung Kim. . Add --max-stack option to limit callchain stack scan in 'top' and 'report', improving callchain processing when reducing the stack depth is an option, from Waiman Long. . Add new option --ignore-vmlinux for perf top, from Willy Tarreau. * 'perf trace' enhancements: . 'perf trace' now can can use a 'perf probe' dynamic tracepoints to hook into the userspace -> kernel pathname copy so that it can map fds to pathnames without reading /proc/pid/fd/ symlinks. From Arnaldo Carvalho de Melo. . Show VFS path associated with fd in live sessions, using a 'vfs_getname' 'perf probe' created dynamic tracepoint or by looking at /proc/pid/fd, from Arnaldo Carvalho de Melo. . Add 'trace' beautifiers for lots of syscall arguments, from Arnaldo Carvalho de Melo. . Implement more compact 'trace' output by suppressing zeroed args, from Arnaldo Carvalho de Melo. . Show thread COMM by default in 'trace', from Arnaldo Carvalho de Melo. . Add option to show full timestamp in 'trace', from David Ahern. . Add 'record' command in 'trace', to record raw_syscalls:*, from David Ahern. . Add summary option to dump syscall statistics in 'trace', from David Ahern. . Improve error messages in 'trace', providing hints about system configuration steps needed for using it, from Ramkumar Ramachandra. . 'perf trace' now emits hints as to why tracing is not possible, helping the user to setup the system to allow tracing in the desired permission granularity, telling if the problem is due to debugfs not being mounted or with not enough permission for !root, /proc/sys/kernel/perf_event_paranoit value, etc. From Arnaldo Carvalho de Melo. * 'perf record' enhancements: . Check maximum frequency rate for record/top, emitting better error messages, from Jiri Olsa. . 'perf record' code cleanups, from David Ahern. . Improve write_output error message in 'perf record', from Adrian Hunter. . Allow specifying B/K/M/G unit to the --mmap-pages arguments, from Jiri Olsa. . Fix command line callchain attribute tests to handle the new -g/--call-chain semantics, from Arnaldo Carvalho de Melo. * 'perf kvm' enhancements: . Disable live kvm command if timerfd is not supported, from David Ahern. . Fix detection of non-core features, from David Ahern. * 'perf list' enhancements: . Add usage to 'perf list', from David Ahern. . Show error in 'perf list' if tracepoints not available, from Pekka Enberg. * 'perf probe' enhancements: . Support "$vars" meta argument syntax for local variables, allowing asking for all possible variables at a given probe point to be collected when it hits, from Masami Hiramatsu. * 'perf sched' enhancements: . Address the root cause of that 'perf sched' stack initialization build slowdown, by programmatically setting a big array after moving the global variable back to the stack. Fix from Adrian Hunter. * 'perf script' enhancements: . Set up output options for in-stream attributes, from Adrian Hunter. . Print addr by default for BTS in 'perf script', from Adrian Juntmer * 'perf stat' enhancements: .

Add units to nanosec-based counters in 'perf stat', from David Ahern. . Remove bogus info when using 'perf stat' -e cycles/instructions, from Ramkumar Ramachandra. * 'perf lock' enhancements: . 'perf lock' fixes and cleanups, from Davidlohr Bueso. * 'perf test' enhancements: . Fixup PERF_SAMPLE_TRANSACTION handling in sample synthesizing and 'perf test', from Adrian Hunter. . Clarify the "sample parsing" test entry, from Arnaldo Carvalho de Melo. . Consider PERF_SAMPLE_TRANSACTION in the "sample parsing" test, from Arnaldo Carvalho de Melo. . Memory leak fixes in 'perf test', from Felipe Pena. * 'perf bench' enhancements: . Change the procps visible command-name of invididual benchmark tests plus cleanups, from Ingo Molnar. * Generic perf tooling infrastructure/plumbing changes: . Separating data file properties from session, code reorganization from Jiri Olsa. . Fix version when building out of tree, as when using one of these: $ make help | grep perf perf-tar-src-pkg - Build perf-3.12.0.tar source tarball perf-targz-src-pkg - Build perf-3.12.0.tar.gz source tarball perf-tarbz2-src-pkg - Build perf-3.12.0.tar.bz2 source tarball perf-tarxz-src-pkg - Build perf-3.12.0.tar.xz source tarball $ from David Ahern. .

2013-11-09uprobes: Fix the memory out of bound overwrite in copy_insn()Oleg Nesterov1-22/+21
1. copy_insn() doesn't look very nice, all calculations are confusing and it is not immediately clear why do we read the 2nd page first. 2. The usage of inode->i_size is wrong on 32-bit machines. 3. "Instruction at end of binary" logic is simply wrong, it doesn't handle the case when uprobe->offset > inode->i_size. In this case "bytes" overflows, and __copy_insn() writes to the memory outside of uprobe->arch.insn. Yes, uprobe_register() checks i_size_read(), but this file can be truncated after that. All i_size checks are racy, we do this only to catch the obvious mistakes. Change copy_insn() to call __copy_insn() in a loop, simplify and fix the bytes/nbytes calculations. Note: we do not care if we read extra bytes after inode->i_size if we got the valid page. This is fine because the task gets the same page after page-fault, and arch_uprobe_analyze_insn() can't know how many bytes were actually read anyway. Signed-off-by: Oleg Nesterov <oleg@redhat.com>

2013-11-07parisc: sticon - unbreak on 64bit kernelHelge Deller3-80/+158
STI text console (sticon) was broken on 64bit machines with more than 4GB RAM and this lead in some cases to a kernel crash. Since sticon uses the 32bit STI API it needs to keep pointers to memory below 4GB. But on a 64bit kernel some memory regions (e.g. the kernel stack) might be above 4GB which then may crash the kernel in the STI functions. Additionally sticon didn't selected the built-in framebuffer fonts by default. This is now fixed. On a side-note: Theoretically we could enhance the sticon driver to use the 64bit STI API. But - beside the fact that some machines don't provide a 64bit STI ROM - this would just add complexity. Signed-off-by: Helge Deller <deller@gmx.de> Cc: stable@vger.kernel.org # 3.8+

2013-11-07smp, ARC: kill SMP single function call interruptJiang Liu1-6/+1
Commit 9a46ad6d6df3b54 "smp: make smp_call_function_many() use logic similar to smp_call_function_single()" has unified the way to handle single and multiple cross-CPU function calls. Now only one interrupt is needed for architecture specific code to support generic SMP function call interfaces, so kill the redundant single function call interrupt.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull staging driver update from Greg KH: "Here's the big drivers/staging/ update for 3.13-rc1. Nothing major here, just a _ton_ of fixes and cleanups, mostly driven by the new round of OPW applicants, but also there are lots of other people doing staging tree cleanups these days in order to help get the drivers into mergable shape. We also merge, and then revert, the ktap code, as Ingo and the other perf/ftrace developers feel it should go into the "real" part of the kernel with only a bit more work, so no need to put it in staging for now. All of this has been in linux-next for a while with no reported issues" * tag 'staging-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1045 commits) staging: drm/imx: fix return value check in ipu_add_subdevice_pdata() Staging: zram: Fix access of NULL pointer Staging: zram: Fix variable dereferenced before check Staging: rtl8187se: space prohibited before semicolon in r8185b_init.c Staging: rtl8187se: fix space prohibited after that open parenthesis '(' in r8185b_init.c Staging: rtl8187se: fix braces {} are not necessary for single statement blocks in r8185b_init.c Staging: rtl8187se: fix trailing whitespace in r8185b_init.c Staging: rtl8187se: fix please, no space before tabs in r8185b_init.c drivers/staging/nvec/Kconfig: remove trailing whitespace Staging: dwc2: Fix variable dereferenced before check Staging: xgifb: fix braces {} are not necessary for any arm of this statement staging: rtl8192e: remove unneeded semicolons staging: rtl8192e: use true and false for bool variables staging: ft1000: return values corrected in scram_start_dwnld staging: ft1000: change values of status return variable in write_dpram32_and_check staging: bcm: Remove unnecessary pointer casting imx-drm: ipuv3-crtc: Invert IPU DI0 clock polarity staging: r8188eu: Fix sparse warnings in rtl_p2p.c staging: r8188eu: Fix sparse warnings in rtw_mlme_ext.c staging: r8188eu: Fix sparse warnings in rtl8188e.cmd.c ...
