[kallsyms] f5fc9abc4e: BUG: KASAN: null-ptr-deref on address (null)

by kernel test robot

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git kallsyms commit f5fc9abc4e23dccfa1fc35892cf36a416d1e6aee Author: Ard Biesheuvel <ard.biesheuvel(a)linaro.org> AuthorDate: Fri Jan 15 10:51:22 2016 +0100 Commit: Kees Cook <keescook(a)chromium.org> CommitDate: Mon Jan 25 15:35:04 2016 -0800 kallsyms: add support for relative offsets in kallsyms address table Similar to how relative extables are implemented, it is possible to emit the kallsyms table in such a way that it contains offsets relative to some anchor point in the kernel image rather than absolute addresses. The benefit is that such table entries are no longer subject to dynamic relocation when the build time and runtime offsets of the kernel image are different. Also, on 64-bit architectures, it essentially cuts the size of the address table in half since offsets can typically be expressed in 32 bits. Since it is useful for some architectures (like x86) to retain the ability to emit absolute values as well, this patch adds support for both, by emitting absolute addresses as positive 32-bit values, and addresses relative to _text as negative values, which are subtracted from the runtime address of _text to produce the actual address. Positive values are used as they are found in the table. Support for the above is enabled by setting CONFIG_KALLSYMS_TEXT_RELATIVE.

by kernel test robot

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is yhuang/dbg_d6980ef325 commit d3b24f87c85f0c96d7b90af7fb2fd6ddbf4c5dac Author: Kan Liang <kan.liang(a)intel.com> AuthorDate: Thu Jan 21 15:52:37 2016 +0000 Commit: Huang Ying <ying.huang(a)intel.com> CommitDate: Mon Jan 25 11:10:56 2016 +0800 perf/core: find auxiliary events in running pmus list perf_event_aux funciton goes through pmus list to find proper auxiliary events to output. The pmus list consists of all possible pmus in the system, that may or may not be running at the moment, while the auxiliary events must be from the running pmus. Therefore searching non-running pmus is unnecessary and expensive especially when there are many non-running pmus on the list. For example, the brk test case in lkp triggers many mmap operations, at the time, perf with cycles:pp is also running on the system. As a result, many perf_event_aux are invoked, and each would search the whole pmus list. If we enable the uncore support (even when uncore event are not really used), dozens of uncore pmus will be added into pmus list, which can significantly decrease brk_test's ops_per_sec. Based on our test, the ops_per_sec without uncore patch is 2647573, while the ops_per_sec with uncore patch is only 1768444, which is a 33.2% reduction. This patch introduces a running_pmus list which only tracks the running pmus in the system. The perf_event_aux uses running_pmus list instead of pmus list to find auxiliary events.
