[PATCH AUTOSEL 4.19 008/219] ARM: dts: imx51: Fix memory node duplication

by Sasha Levin

From: Fabio Estevam <festevam(a)gmail.com> [ Upstream commit 6a9681168b83c62abfa457c709f2f4b126bd6b92 ] Boards based on imx51 have duplicate memory nodes: - One coming from the board dts file: memory@ - One coming from the imx51.dtsi file. Fix the duplication by removing the memory node from the dtsi file and by adding 'device_type = "memory";' in the board dts.

[PATCH 02/12] fs_parse: fix fs_param_v_optional handling

by Miklos Szeredi

String options always have parameters, hence the check for optional parameter will never trigger. Check for param type being a flag first (flag is the only type that does not have a parameter) and report "Missing value" if the parameter is mandatory. Tested with gfs2's "quota" option, which is currently the only user of fs_param_v_optional.

[PATCH for linux 4.4.y/3.16.y] fs/dcache: move security_d_instantiate() behind attaching dentry to inode

During backport 1e2e547a93a "do d_instantiate/unlock_new_inode combinations safely", there was a error instantiating sequence of attaching dentry to inode and calling security_d_instantiate().

[PATCH 56/63] perf tests: Fix out of bounds memory access

by Arnaldo Carvalho de Melo

From: Leo Yan <leo.yan(a)linaro.org> The test case 'Read backward ring buffer' failed on 32-bit architectures which were found by LKFT perf testing. The test failed on arm32 x15 device, qemu_arm32, qemu_i386, and found intermittent failure on i386; the failure log is as below: 50: Read backward ring buffer : --- start --- test child forked, pid 510 Using CPUID GenuineIntel-6-9E-9 mmap size 1052672B mmap size 8192B Finished reading overwrite ring buffer: rewind free(): invalid next size (fast) test child interrupted ---- end ---- Read backward ring buffer: FAILED! The log hints there have issue for memory usage, thus free() reports error 'invalid next size' and directly exit for the case. Finally, this issue is root caused as out of bounds memory access for the data array 'evsel->id'. The backward ring buffer test invokes do_test() twice. 'evsel->id' is allocated at the first call with the flow: test__backward_ring_buffer() `-> do_test() `-> evlist__mmap() `-> evlist__mmap_ex() `-> perf_evsel__alloc_id() So 'evsel->id' is allocated with one item, and it will be used in function perf_evlist__id_add(): evsel->id[0] = id evsel->ids = 1 At the second call for do_test(), it skips to initialize 'evsel->id' and reuses the array which is allocated in the first call. But 'evsel->ids' contains the stale value. Thus: evsel->id[1] = id -> out of bound access evsel->ids = 2 To fix this issue, we will use evlist__open() and evlist__close() pair functions to prepare and cleanup context for evlist; so 'evsel->id' and 'evsel->ids' can be initialized properly when invoke do_test() and avoid the out of bounds memory access.
