As can be seen in [recent news](https://www.datanami.com/2023/10/16/cloudera-hit-with-240-million-judgement-over-erasure-coding/)
|
||||
there has been lawsuits related to possible patents of aspects of erasure coding functionality.
|
||||
|
||||
As a possible mitigation it is possible to use the tag `nopshufb` when compiling any code which includes this package.
|
||||
This will remove all inclusion and use of `PSHUFB` and equivalent on other platforms.
|
||||
|
||||
This is done by adding `-tags=nopshufb` to `go build` and similar commands that produce binary output.
|
||||
|
||||
The removed code may not be infringing and even after `-tags=nopshufb` there may still be infringing code left.
