Add hist.percentage option for setting default value of the symbol_conf.filter_relative. It affects the output of various perf commands (like perf report, top and diff) only if filter(s) applied.

The --percentage option is for controlling overhead percentage displayed. It can only receive either of "relative" or "absolute". "relative" means it's relative to filtered entries only so that the sum of shown entries will be always 100%. "absolute" means it retains the original value before and after the filter is applied. $ perf report -s comm # Overhead Command # ........ ............ # 74.19% cc1 7.61% gcc 6.11% as 4.35% sh 4.14% make 1.13% fixdep ... $ perf report -s comm -c cc1,gcc --percentage absolute # Overhead Command # ........ ............ # 74.19% cc1 7.61% gcc $ perf report -s comm -c cc1,gcc --percentage relative # Overhead Command # ........ ............ # 90.69% cc1 9.31% gcc Note that it has zero effect if no filter was applied.

When filtering by thread, dso or symbol on TUI it also update total period so that the output shows different result than no filter - the percentage changed to relative to filtered entries only. Sometimes this is not desired since users might expect same results with filter. So new filtered_* fields to hists->stats to count them separately. They'll be controlled/used by user later.

perf stat did initialize the stats structure used to compute stddev etc. incorrectly. It merely zeroes it. But one member (min) needs to be set to a non zero value. This causes min to be not computed at all. Call init_stats() correctly. It doesn't matter for stat currently because it doesn't use min, but it's still better to do it correctly. The other users of statistics are already correct.

The dwarf_getcfi() only checks .debug_frame section for CFI, but as most binaries only have .eh_frame it'd return NULL and it makes some variables inaccessible.

As Namhyung reported(https://lkml.org/lkml/2014/4/1/89), current perf-probe -L option doesn't handle errors in line-range searching correctly. It causes a SEGV if an error occured in the line-range searching. ---- $ perf probe -x ./perf -v -L map__load Open Debuginfo file: /home/namhyung/project/linux/tools/perf/perf fname: util/map.c, lineno:153 New line range: 153 to 2147483647 path: (null) Segmentation fault (core dumped) ---- This is because line_range_inline_cb() ignores errors from find_line_range_by_line() which means that lr->path is already freed on the error path in find_line_range_by_line(). As a result, get_real_path() accesses the lr->path and it causes a NULL pointer exception. This fixes line_range_inline_cb() to handle the error correctly, and report it to the caller. Anyway, this just fixes a possible SEGV bug, Namhyung's patch is also required.

The commit 5a62257a ("perf probe: Replace line_list with intlist") replaced line_list to intlist but it has a problem that if a same line was added again, it'd return -EEXIST rather than 1. Since line_range_walk_cb() only checks the result being negative, it resulted in failure or segfault sometimes.

This patch fixes I/O errors with the sym53c8xx_2 driver when the disk returns QUEUE FULL status. When the controller encounters an error (including QUEUE FULL or BUSY status), it aborts all not yet submitted requests in the function sym_dequeue_from_squeue. This function aborts them with DID_SOFT_ERROR. If the disk has full tag queue, the request that caused the overflow is aborted with QUEUE FULL status (and the scsi midlayer properly retries it until it is accepted by the disk), but the sym53c8xx_2 driver aborts the following requests with DID_SOFT_ERROR --- for them, the midlayer does just a few retries and then signals the error up to sd. The result is that disk returning QUEUE FULL causes request failures. The error was reproduced on 53c895 with COMPAQ BD03685A24 disk (rebranded ST336607LC) with command queue 48 or 64 tags. The disk has 64 tags, but under some access patterns it return QUEUE FULL when there are less than 64 pending tags. The SCSI specification allows returning QUEUE FULL anytime and it is up to the host to retry.

Commit 8f619b54 ("powerpc/ppc64: Do not turn AIL (reloc-on interrupts) too early") added code to set the AIL bit in the LPCR without checking whether the kernel is running in hypervisor mode. The result is that when the kernel is running as a guest (i.e., under PowerKVM or PowerVM), the processor takes a privileged instruction interrupt at that point, causing a panic. The visible result is that the kernel hangs after printing "returning from prom_init". This fixes it by checking for hypervisor mode being available before setting LPCR. If we are not in hypervisor mode, we enable relocation-on interrupts later in pSeries_setup_arch using the H_SET_MODE hcall.

One was a late fix and the other a consequence of overlooking the whole requeuing logic. The first change caused our documentation to be incorrect, and the second made us aware that we need to explicitly add more details to it.

Pull yet more networking updates from David Miller: 1) Various fixes to the new Redpine Signals wireless driver, from Fariya Fatima. 2) L2TP PPP connect code takes PMTU from the wrong socket, fix from Dmitry Petukhov. 3) UFO and TSO packets differ in whether they include the protocol header in gso_size, account for that in skb_gso_transport_seglen(). From Florian Westphal. 4) If VLAN untagging fails, we double free the SKB in the bridging output path. From Toshiaki Makita. 5) Several call sites of sk->sk_data_ready() were referencing an SKB just added to the socket receive queue in order to calculate the second argument via skb->len. This is dangerous because the moment the skb is added to the receive queue it can be consumed in another context and freed up. It turns out also that none of the sk->sk_data_ready() implementations even care about this second argument. So just kill it off and thus fix all these use-after-free bugs as a side effect. 6) Fix inverted test in tcp_v6_send_response(), from Lorenzo Colitti. 7) pktgen needs to do locking properly for LLTX devices, from Daniel Borkmann. 8) xen-netfront driver initializes TX array entries in RX loop :-) From Vincenzo Maffione. 9) After refactoring, some tunnel drivers allow a tunnel to be configured on top itself.

Pull llvm patches from Behan Webster: "These are some initial updates to support compiling the kernel with clang. These patches have been through the proper reviews to the best of my ability, and have been soaking in linux-next for a few weeks. These patches by themselves still do not completely allow clang to be used with the kernel code, but lay the foundation for other patches which are still under review. Several other of the LLVMLinux patches have been already added via maintainer trees" * tag 'llvmlinux-for-v3.15' of git://git.linuxfoundation.org/llvmlinux/kernel: x86: LLVMLinux: Fix "incomplete type const struct x86cpu_device_id" x86 kbuild: LLVMLinux: More cc-options added for clang x86, acpi: LLVMLinux: Remove nested functions from Thinkpad ACPI LLVMLinux: Add support for clang to compiler.h and new compiler-clang.h LLVMLinux: Remove warning about returning an uninitialized variable kbuild: LLVMLinux: Fix LINUX_COMPILER definition script for compilation with clang Documentation: LLVMLinux: Update Documentation/dontdiff kbuild: LLVMLinux: Adapt warnings for compilation with clang kbuild: LLVMLinux: Add Kbuild support for building kernel with Clang

Pull SCSI target updates from Nicholas Bellinger: "Here are the target pending updates for v3.15-rc1. Apologies in advance for waiting until the second to last day of the merge window to send these out. The highlights this round include: - iser-target support for T10 PI (DIF) offloads (Sagi + Or) - Fix Task Aborted Status (TAS) handling in target-core (Alex Leung) - Pass in transport supported PI at session initialization (Sagi + MKP + nab) - Add WRITE_INSERT + READ_STRIP T10 PI support in target-core (nab + Sagi) - Fix iscsi-target ERL=2 ASYNC_EVENT connection pointer bug (nab) - Fix tcm_fc use-after-free of ft_tpg (Andy Grover) - Use correct ib_sg_dma primitives in ib_isert (Mike Marciniszyn) Also, note the virtio-scsi + vhost-scsi changes to expose T10 PI metadata into KVM guest have been left-out for now, as there where a few comments from MST + Paolo that where not able to be addressed in time for v3.15. Please expect this feature for v3.16-rc1" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (43 commits) ib_srpt: Use correct ib_sg_dma primitives target/tcm_fc: Rename ft_tport_create to ft_tport_get target/tcm_fc: Rename ft_{add,del}_lport to {add,del}_wwn target/tcm_fc: Rename structs and list members for clarity target/tcm_fc: Limit to 1 TPG per wwn target/tcm_fc: Don't export ft_lport_list target/tcm_fc: Fix use-after-free of ft_tpg target: Add check to prevent Abort Task from aborting itself target: Enable READ_STRIP emulation in target_complete_ok_work target/sbc: Add sbc_dif_read_strip software emulation target: Enable WRITE_INSERT emulation in target_execute_cmd target/sbc: Add sbc_dif_generate software emulation target/sbc: Only expose PI read_cap16 bits when supported by fabric target/spc: Only expose PI mode page bits when supported by fabric target/spc: Only expose PI inquiry bits when supported by fabric target: Pass in transport supported PI at session initialization target/iblock: Fix double bioset_integrity_free bug Target/sbc: Initialize COMPARE_AND_WRITE write_sg scatterlist target/rd: T10-Dif: RAM disk is allocating more space than required. iscsi-target: Fix ERL=2 ASYNC_EVENT connection pointer bug ...
