scripts/gdb: fix lx-symbols 'gdb.error' while loading modules

2020-07-29T08:19:48+00:00

[ Upstream commit 7359608a271ce81803de148befefd309baf88c76 ] Commit ed66f991bb19 ("module: Refactor section attr into bin attribute") removed the 'name' field from 'struct module_sect_attr' triggering the following error when invoking lx-symbols: (gdb) lx-symbols loading vmlinux scanning for modules in linux/build loading @0xffffffffc014f000: linux/build/drivers/net/tun.ko Python Exception There is no member named name.: Error occurred in Python: There is no member named name. This patch fixes the issue taking the module name from the 'struct attribute'.

scripts/decode_stacktrace: strip basepath from all paths

2020-07-29T08:19:48+00:00

[ Upstream commit d178770d8d21489abf5bafefcbb6d5243b482e9a ] Currently the basepath is removed only from the beginning of the string. When the symbol is inlined and there's multiple line outputs of addr2line, only the first line would have basepath removed. Change to remove the basepath prefix from all lines.

scripts/dtc: Update to upstream version v1.6.0-11-g9d7888cbf19c

2020-07-08T01:18:54+00:00

Sync with upstream dtc primarily to pickup the I2C bus check fixes. The interrupt_provider check is noisy, so turn it off for now. This adds the following commits from upstream: 9d7888cbf19c dtc: Consider one-character strings as strings 8259d59f59de checks: Improve i2c reg property checking fdabcf2980a4 checks: Remove warning for I2C_OWN_SLAVE_ADDRESS 2478b1652c8d libfdt: add extern "C" for C++ f68bfc2668b2 libfdt: trivial typo fix 7be250b4d059 libfdt: Correct condition for reordering blocks 81e0919a3e21 checks: Add interrupt provider test 85e5d839847a Makefile: when building libfdt only, do not add unneeded deps b28464a550c5 Fix some potential unaligned accesses in dtc Signed-off-by: Rob Herring Link: https://lore.kernel.org/lkml/20200629193203.2727682-1-robh@kernel.org/ Signed-off-by: Joel Stanley

recordmcount: support >64k sections

2020-06-30T19:36:18+00:00

[ Upstream commit 4ef57b21d6fb49d2b25c47e4cff467a0c2c8b6b7 ] When compiling a kernel with Clang and LTO, we need to run recordmcount on vmlinux.o with a large number of sections, which currently fails as the program doesn't understand extended section indexes. This change adds support for processing binaries with >64k sections.

kbuild: improve cc-option to clean up all temporary files

2020-06-30T19:36:18+00:00

[ Upstream commit f2f02ebd8f3833626642688b2d2c6a7b3c141fa9 ] When cc-option and friends evaluate compiler flags, the temporary file $$TMP is created as an output object, and automatically cleaned up. The actual file path of $$TMP is ..tmp, here is the process ID of $(shell ...) invoked from cc-option. (Please note $$$$ is the escape sequence of $$). Such garbage files are cleaned up in most cases, but some compiler flags create additional output files. For example, -gsplit-dwarf creates a .dwo file. When CONFIG_DEBUG_INFO_SPLIT=y, you will see a bunch of ..dwo files left in the top of build directories. You may not notice them unless you do 'ls -a', but the garbage files will increase every time you run 'make'. This commit changes the temporary object path to .tmp_/tmp, and removes .tmp_ directory when exiting. Separate build artifacts such as *.dwo will be cleaned up all together because their file paths are usually determined based on the base name of the object. Another example is -ftest-coverage, which outputs the coverage data into .gcno Signed-off-by: Masahiro Yamada Signed-off-by: Sasha Levin

modpost: fix -i (--ignore-errors) MAKEFLAGS detection

2020-06-24T15:49:02+00:00

[ Upstream commit 91e6ee581270b8ae970f028b898314d73f16870b ] $(filter -i,$(MAKEFLAGS)) works only in limited use-cases. The representation of $(MAKEFLAGS) depends on various factors: - GNU Make version (version 3.8x or version 4.x) - The presence of other flags like -j In my experiments, $(MAKEFLAGS) is expanded as follows: * GNU Make 3.8x: * without -j option: --no-print-directory -Rri * with -j option: --no-print-directory -Rr --jobserver-fds=3,4 -j -i * GNU Make 4.x: * without -j option: irR --no-print-directory * with -j option: irR -j --jobserver-fds=3,4 --no-print-directory For GNU Make 4.x, the flags are grouped as 'irR', which does not work. For the single thread build with GNU Make 3.8x, the flags are grouped as '-Rri', which does not work either. To make it work for all cases, do likewise as commit 6f0fa58e4596 ("kbuild: simplify silent build (-s) detection"). BTW, since commit ff9b45c55b26 ("kbuild: modpost: read modules.order instead of $(MODVERDIR)/*.mod"), you also need to pass -k option to build final *.ko files. 'make -i -k' ignores compile errors in modules, and build as many remaining *.ko as possible. Please note this feature is kind of dangerous if other modules depend on the broken module because the generated modules will lack the correct module dependency or CRC. Honestly, I am not a big fan of it, but I am keeping this feature.

mksysmap: Fix the mismatch of '.L' symbols in System.map

2020-06-24T15:48:30+00:00

[ Upstream commit 72d24accf02add25e08733f0ecc93cf10fcbd88c ] When System.map was generated, the kernel used mksysmap to filter the kernel symbols, but all the symbols with the second letter 'L' in the kernel were filtered out, not just the symbols starting with 'dot + L'. For example: ashimida@ubuntu:~/linux$ cat System.map |grep ' .L' ashimida@ubuntu:~/linux$ nm -n vmlinux |grep ' .L' ffff0000088028e0 t bLength_show ...... ffff0000092e0408 b PLLP_OUTC_lock ffff0000092e0410 b PLLP_OUTA_lock The original intent should be to filter out all local symbols starting with '.L', so the dot should be escaped.
