kernel: pipe: iovec overrun leading to memory corruption

It was found that the Linux kernel's implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array...

Simple Ruby Exec with Open and Pipe

I was researching something else and thought this was a cool way to execute a command through the open method in ruby: 1 | open"|CMD" ---|--- The key is starting the open with pipe. For example, 1 | open"|ls" ---|--- Or to exec and print the result in one line: 1 | open"|ls".each |out| puts out...
