Hi !
I'm trying to detect false positive sparse messages by taking the pattern and scanning with coccinelle for it so that the fix could be generated. Basically the identification seems to be working (a type-check on var is stil missing - but thats a different issue) - the problem though is that I'm unable to insert the (__force __be16) cast in the patch rule as coccinelle is refusing hose lines. Any hint how that could be done or is the problem the syntactic oddity of having a unknown keyworkd followed by a type that is confusing coccinelle here ? thx! hofrat virtual report virtual patch @acheck depends on report@ identifier var; position p; @@ ( * var = be16_to_cpu@p(var); | * var = be32_to_cpu@p(var); | * var = be64_to_cpu@p(var); | * var = le16_to_cpu@p(var); | * var = le32_to_cpu@p(var); | * var = le64_to_cpu@p(var); ) @script:python depends on report@ p << acheck.p; @@ msg = "forced endiannes annotation needed" coccilib.report.print_report(p[0],msg) @afix depends on patch@ identifier var; position p; typedef __be16, __be32, __b64, __le16, __le32, __le64; @@ ( - var = be16_to_cpu@p(var); + var = be16_to_cpu((__force __be16)var); | - var = be32_to_cpu@p(var); + var = be32_to_cpu((__force __be32)var); | - var = be64_to_cpu@p(var); + var = be64_to_cpu((__force __be64)var); | - var = le16_to_cpu@p(var); + var = le16_to_cpu((__force __le16)var); | - var = le32_to_cpu@p(var); + var = le32_to_cpu((__force __le32)var); | - var = le64_to_cpu@p(var); + var = le64_to_cpu((__force __le64)var); ) @script:python depends on patch@ p << afix.p; @@ msg = "forced endiannes annotation added" coccilib.report.print_report(p[0],msg) _______________________________________________ Cocci mailing list Cocci@systeme.lip6.fr https://systeme.lip6.fr/mailman/listinfo/cocci
