From 2b18ab36cf7e956fb5b5ee12847e94fc66d496f4 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 6 Jul 2010 19:05:31 +0200 Subject: net/wireless: use generic_file_llseek in debugfs The default llseek operation is changing from default_llseek to no_llseek, so all code relying on the current behaviour needs to make that explicit. The wireless driver infrastructure and some of the drivers make use of generated debugfs files, so they cannot be converted by our script that automatically determines the right operation. All these files use debugfs and they typically rely on simple_read_from_buffer, so the best llseek operation here is generic_file_llseek. Signed-off-by: Arnd Bergmann Cc: "John W.

The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...
