scripts/gdb: fix debugging modules on s390

2019-10-19T10:32:33Z

Currently lx-symbols assumes that module text is always located at module->core_layout->base, but s390 uses the following layout: +------+ <- module->core_layout->base | GOT | +------+ <- module->core_layout->base + module->arch->plt_offset | PLT | +------+ <- module->core_layout->base + module->arch->plt_offset + | TEXT | module->arch->plt_size +------+ Therefore, when trying to debug modules on s390, all the symbol addresses are skewed by plt_offset + plt_size. Fix by adding plt_offset + plt_size to module_addr in load_module_symbols().

scripts/gdb: fix lx-dmesg when CONFIG_PRINTK_CALLER is set

2019-10-19T10:32:31Z

When CONFIG_PRINTK_CALLER is set, struct printk_log contains an additional member caller_id. This affects the offset of the log text. Account for this by using the type information from gdb to determine all the offsets instead of using hardcoded values. This fixes following error: (gdb) lx-dmesg Python Exception embedded null character: Error occurred in Python command: embedded null character The read_u* utility functions now take an offset argument to make them easier to use.

coccinelle: api/devm_platform_ioremap_resource: remove useless script

2019-10-17T16:05:56Z

While it is useful for new drivers to use devm_platform_ioremap_resource, this script is currently used to spam maintainers, often updating very old drivers. The net benefit is the removal of 2 lines of code in the driver but the review load for the maintainers is huge. As of now, more that 560 patches have been sent, some of them obviously broken, as in: https://lore.kernel.org/lkml/9bbcce19c777583815c92ce3c2ff2586@www.loen.fr/ Remove the script to reduce the spam.

recordmcount: Fix nop_mcount() function

2019-10-13T00:49:33Z

The removal of the longjmp code in recordmcount.c mistakenly made the return of make_nop() being negative an exit of nop_mcount(). It should not exit the routine, but instead just not process that part of the code. By exiting with an error code, it would cause the update of recordmcount to fail some files which would fail the build if ftrace function tracing was enabled.

nsdeps: make generated patches independent of locale

2019-10-07T16:25:29Z

scripts/nsdeps automatically generates a patch to add MODULE_IMPORT_NS tags, and what is nicer, it sorts the lines alphabetically with the 'sort' command. However, the output from the 'sort' command depends on locale. For example, I got this: $ { echo usbstorage; echo usb_storage; } | LANG=en_US.UTF-8 sort usbstorage usb_storage $ { echo usbstorage; echo usb_storage; } | LANG=C sort usb_storage usbstorage So, this means people might potentially send different patches. This kind of issue was reported in the past, for example, commit f55f2328bb28 ("kbuild: make sorting initramfs contents independent of locale"). Adding 'LANG=C' is a conventional way of fixing when a deterministic result is desirable. I added 'LANG=C' very close to the 'sort' command since changing locale affects the language of error messages etc. We should respect users' choice as much as possible.

nsdeps: fix hashbang of scripts/nsdeps

2019-10-07T16:25:21Z

This script does not use bash-extension. I am guessing this hashbang was copied from scripts/coccicheck, which really uses bash-extension. /bin/sh is enough for this script. Reviewed-by: Matthias Maennich Signed-off-by: Masahiro Yamada Signed-off-by: Jessica Yu
