meta/meta-selftest/meta-skeleton: Update LICENSE variable to use SPDX license identifiers

2022-02-20T16:45:25+00:00

An automated conversion using scripts/contrib/convert-spdx-licenses.py to convert to use the standard SPDX license identifiers. Two recipes in meta-selftest were not converted as they're that way specifically for testing. A change in linux-firmware was also skipped and may need a more manual tweak.

systemtap: backport buffer size tuning patches

2022-02-01T07:31:18+00:00

Backport a nunber of patches from upstream to tune the buffer size on machines with a "small amount" of memory, which appears to mean less than 4GB. (From OE-Core rev: d1e1c8698a5143a1e5d80d172105b76c57b85dd6) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

systemtap: fix vsprintf errors

2022-01-15T16:23:24+00:00

In some configurations (such as 32-bit arm), using printf() causes gcc errors. Backport a patch from upstream to fix this. (From OE-Core rev: 6340a6477ddf0fee6c18cf99262704a715491f60) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

systemtap: upgrade 4.5 -> 4.6

2021-11-23T10:53:15+00:00

support for 64-bit RISC-V architecture, liveness analysis for guru-mode write operations, bpf syscall_any and abort() tapsets, bpf foreach iteration of multi-key arrays, return of inter-cpu output ordering Changelog is as follows: = SystemTap frontend (stap) changes - stap-prep now tries to download the main kernel debuginfo file from a debuginfod server, if configured. = SystemTap backend changes - SystemTap has added support for the 64-bit RISC-V architecture. - SystemTap now uses DynInst to perform a liveness analysis on target variables and warn when a guru-mode modification to a variable will have no effect. The liveness analysis is currently done on x86_64, PowerPC, and AArch64. - The kernel-user relayfs transport again sorts messages into a total time order across CPUs. High output-volume scripts may need a larger "-s BUF" parameter to reliably transfer. "-b" bulk mode is also available again as an alternative. - The bpf backend now supports foreach iteration in multi-key associative arrays. = SystemTap tapset changes - Updated syscall_any tapset mapping to include newer syscalls. - syscall_any tapset can be used by the bpf backend. - abort() tapset can be used by the bpf backend. = Known issues with this release - There are known issues on kernel 5.10+ after adapting to set_fs() removal, with some memory accesses that previously returned valid data instead returning -EFAULT (see PR26811). - An sdt probe cannot parse a parameter that uses a segment register. (PR13429) - The presence of a line such as *CFLAGS += $(call cc-option, -fno-var-tracking-assignments) in older linux kernel Makefile unnecessarily reduces debuginfo quality, consider removing that line if you build kernels. Linux 5.10+ fixes this. = Bugs fixed for this release 6562 $SYSTEMTAP_DEBUGINFO_PATH does not work 15724 stapdyn looking for libdyninstAPI_RT.a 26839 Systemtap build failures with clang 27820 abort() tapset not implemented in the bpf mode 27829 support for floating point values passed through sdt.h markers 27864 loc2stap.cxx assertion failure on loc_unavailable type location, rawhide 27881 failed to extend vma mapped entry when the address is adjacent 27903 handle f33 glibc $$parms 27932 List Python as a prerequisite in README 27933 Use of unitialized functioncall synthetic field in 27934 failure to attach statement 27940 The /* pc=0x... */ is no longer printed by "stap -v -L 'kernel.function("*")' 27942 testsuite/systemtap.base/perf.sh drop bashism 27984 stap skipping partially-inlined instance, but it is not inline function actually 28070 extend vma end address to the different module 28079 adapt to kernel 5.14 task_struct.__state change 28084 autoconf-x86-uniregs.c compile failled with -Werror cause STAPCONF_X86_UNIREGS missing 28140 kernel panic on tracepoint activation in stap module 28184 task_fd_lookup failed on linux 5.11 28244 linux objtool imposes symbol length limits on generated function names 28384 finish nfs_proc tapset port 4.3 string server_ip 28443 Provide syscall_any tapset for bpf 28449 loss of cross-cpu output ordering 28544 procfs_bpf.exp regression due to string handling error 28557 module kprobe insertion on modern kernels (From OE-Core rev: 99ed4a3d78f8224d414bd49d887333a4509529f3) Signed-off-by: Wang Mingyu Signed-off-by: Richard Purdie

meta: Add explict branch to git SRC_URIs

2021-10-30T17:56:47+00:00

There is uncertainty about the default branch name in git going forward. To try and cover the different possible outcomes, add branch names to all git:// and gitsm:// SRC_URI entries. This update was made with the script added to contrib in this patch which aims to help others convert other layers.
