Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

rose: Add length checks to CALL_REQUEST parsing Define some constant offsets for CALL_REQUEST based on the description at <http://www.techfest.com/networking/wan/x25plp.htm> and the definition of ROSE as using 10-digit (5-byte) addresses. Use them consistently. Validate all implicit and explicit facilities lengths. Validate the address length byte rather than either trusting or assuming its value.

[PATCH] mark struct file_operations const 1 Many struct file_operations in the kernel can be "const".
