checkpatch/coding-style: deprecate 80-column warning

2020-05-31T18:00:42Z

Yes, staying withing 80 columns is certainly still _preferred_. But it's not the hard limit that the checkpatch warnings imply, and other concerns can most certainly dominate. Increase the default limit to 100 characters. Not because 100 characters is some hard limit either, but that's certainly a "what are you doing" kind of value and less likely to be about the occasional slightly longer lines. Miscellanea: - to avoid unnecessary whitespace changes in files, checkpatch will no longer emit a warning about line length when scanning files unless --strict is also used - Add a bit to coding-style about alignment to open parenthesis Signed-off-by: Joe Perches Signed-off-by: Linus Torvalds

scripts/gdb: repair rb_first() and rb_last()

2020-05-08T02:27:20Z

The current implementations of the rb_first() and rb_last() gdb functions have a variable that references itself in its instanciation, which causes the function to throw an error if a specific condition on the argument is met. The original author rather intended to reference the argument and made a typo. Referring the argument instead makes the function work as intended.

scripts/decodecode: fix trapping instruction formatting

2020-05-08T02:27:20Z

If the trapping instruction contains a ':', for a memory access through segment registers for example, the sed substitution will insert the '*' marker in the middle of the instruction instead of the line address: 2b: 65 48 0f c7 0f cmpxchg16b %gs:*(%rdi) <-- trapping instruction I started to think I had forgotten some quirk of the assembly syntax before noticing that it was actually coming from the script. Fix it to add the address marker at the right place for these instructions: 28: 49 8b 06 mov (%r14),%rax 2b:* 65 48 0f c7 0f cmpxchg16b %gs:(%rdi) <-- trapping instruction 30: 0f 94 c0 sete %al Fixes: 18ff44b189e2 ("scripts/decodecode: make faulting insn ptr more robust") Signed-off-by: Ivan Delalande Signed-off-by: Andrew Morton Reviewed-by: Borislav Petkov Link: http://lkml.kernel.org/r/20200419223653.GA31248@visor Signed-off-by: Linus Torvalds

gcc-10 warnings: fix low-hanging fruit

2020-05-04T16:16:37Z

Due to a bug-report that was compiler-dependent, I updated one of my machines to gcc-10. That shows a lot of new warnings. Happily they seem to be mostly the valid kind, but it's going to cause a round of churn for getting rid of them.. This is the really low-hanging fruit of removing a couple of zero-sized arrays in some core code. We have had a round of these patches before, and we'll have many more coming, and there is nothing special about these except that they were particularly trivial, and triggered more warnings than most.

kbuild: fix DT binding schema rule again to avoid needless rebuilds

2020-04-23T01:50:26Z

Since commit 7a0496056064 ("kbuild: fix DT binding schema rule to detect command line changes"), this rule is every time re-run even if you change nothing. cmd_dtc takes one additional parameter to pass to the -O option of dtc. We need to pass 'yaml' to if_changed_rule. Otherwise, cmd-check invoked from if_changed_rule is false positive.

scripts/config: allow colons in option strings for sed

2020-04-22T16:10:16Z

Sed broke on some strings as it used colon as a separator. I made it more robust by using \001, which is legit POSIX AFAIK. E.g. ./config --set-str CONFIG_USBNET_DEVADDR "de:ad:be:ef:00:01" failed with: sed: -e expression #1, char 55: unknown option to `s' Signed-off-by: Jeremie Francois (on alpha) Signed-off-by: Masahiro Yamada

checkpatch: fix a typo in the regex for $allocFunctions

Here, we look for function such as 'netdev_alloc_skb_ip_align', so a '_' is missing in the regex.
