* perf tools: Really allow to specify custom CC, AR or LDAlexey Brodkin2015-07-151-3/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 5ef7bbb09f7b ("perf tools: Allow to specify custom linker command") was meant to enable usage non $(CROSS_COMPILE)ld linker during perf building. But implementation didn't take into account the fact that LD is a pre-defined variable in GNU Make. I.e. it is always defined. Which means there's no point to check "LD ?= ..." because it will never succeed. And so LD will be either that explicitly passed to make like this: ------->8------- make LD=path_to_my_ld ... ------->8------- or default value, which is host's "ld". Latter leads to failure of cross-linkage because instead of cross linker "$(CROSS_COMPILE)ld" host's "ld" is used. Fortunately there's a way to do correct substitution of $(CROSS_COMPILE)ld with user defined LD on command-line. As a reference was used implementation in "tools/lib/traceevent/Makefile". Build tested for x86_64 and ARC. Thanks Jiri for this hint.

* perf hists browser: Take the --comm, --dsos, etc filters into accountArnaldo Carvalho de Melo2015-07-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At some point: commit 2c86c7ca7606 Author: Namhyung Kim <namhyung@kernel.org> Date: Mon Mar 17 18:18:54 2014 -0300 perf report: Merge al->filtered with hist_entry->filtered We stopped dropping samples for things filtered via the --comms, --dsos, --symbols, etc, i.e. things marked as filtered in the symbol resolution routines (thread__find_addr_map(), perf_event__preprocess_sample(), etc). But then, in: commit 268397cb2a47 Author: Namhyung Kim <namhyung@kernel.org> Date: Tue Apr 22 14:49:31 2014 +0900 perf top/tui: Update nr_entries properly after a filter is applied We don't take into account entries that were filtered in perf_event__preprocess_sample() and friends, which leads to inconsistency in the browser seek routines, that expects the number of hist_entry->filtered entries to match what it thinks is the number of unfiltered, browsable entries. So, for instance, when we do: perf top --symbols ___non_existent_symbol___ the hist_browser__nr_entries() routine thinks there are no filters in place, uses the hists->nr_entries but all entries are filtered, leading to a segfault. Tested with: perf top --symbols malloc,free --percentage=relative Freezing, by pressing 'f', at any time and doing the math on the percentages ends up with 100%, ditto for: perf top --dsos libpthread-2.20.so,libxul.so --percentage=relative Both were segfaulting, all fixed now. More work needed to do away with checking if filters are in place, we should just use the nr_non_filtered_samples counter, no need to conditionally use it or hists.nr_filter, as what the browser does is just show unfiltered stuff. An audit of how it is being accounted is needed, this is the minimal fix.

* perf symbols: Store if there is a filter in placeArnaldo Carvalho de Melo2015-07-132-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | When setting yup the symbols library we setup several filter lists, for dsos, comms, symbols, etc, and there is code that, if there are filters, do certain operations, like recalculate the number of non filtered histogram entries in the top/report TUI. But they were considering just the "Zoom" filters, when they need to take into account as well the above mentioned filters (perf top --comms, --dsos, etc). So store in symbol_conf.has_filter true if any of those filters is in place.

* tools: Copy lib/hweight.c from the kernel sourcesArnaldo Carvalho de Melo2015-07-093-3/+3
| | | | | | | | | | | | | | | | | | | Instead of accessing it directly, as it uses EXPORT_SYMBOL, that has no meaning in tools/perf and because we removed the stubs for it, i.e. we removed the tools/include/linux/export.h file.

* perf tools: Fix the detached tarball wrt rbtree copyArnaldo Carvalho de Melo2015-07-091-1/+1
| | | | | | | | | | | | | | | | | | | | The python binding build process was still looking at the kernel rbtree.c file, so, when doing a in-tree build it would work, but when creating a tarball using tools/perf/MANIFEST as the contents list and then trying to build the resulting detached sources, it failed. Fix it by removing one level of indirection from rbtree.c in the tools/perf/util/python-ext-sources file.

* perf thread_map: Fix the sizeof() calculation for map entriesArnaldo Carvalho de Melo2015-07-091-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we started adding extra stuff per array entry, growing the size of those entries to more than sizeof(pid_t), we had to convert those sizeof operations to the more robust sizeof(map->map[0]) idiom, that is future proof, i.e. if/when we add more stuff to those entries, that expression will produce the new per-entry size. And besides that, we need to zero out those extra fields, that sometimes may not get filled, like when we couldn't care less about the comms, since we don't need those, but since we will try freeing it at thread_map__delete(), we better fix it. That is why a thread_map__realloc() was provided. But that method wasn't used in thread_map__new_by_uid(), fix it.

| * perf symbols: Check access permission when reading symbol filesLi Zhang2015-06-262-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There 2 problems when reading symbols files: * It doesn't report any errors even if when users specify symbol files which don't exist with --kallsyms or --vmlinux. The result just shows the address without symbols, which is not what is expected. So it's better to report errors and exit the program. * When using command perf report --kallsyms=/proc/kallsyms with a non-root user, symbols are resolved. Then select one symbol and annotate it, it reports the error as the following: Can't annotate __clear_user: No vmlinux file with build id xxx was found. The problem is caused by reading /proc/kcore without access permission. /proc/kcore requires CAP_SYS_RAWIO capability to access, so it needs to change access permission to allow a specific user to read /proc/kcore or use root to execute the perf command. This patch is to report errors when symbol files specified by users don't exist. And check access permission of /proc/kcore when reading it.
