From 4c87158daeeff40e24f5c86a477761e5422867df Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Tue, 16 Jan 2018 00:45:32 +0300 Subject: netfilter: delete /proc THIS_MODULE references /proc has been ignoring struct file_operations::owner field for 10 years. Specifically, it started with commit 786d7e1612f0b0adb6046f19b906609e4fe8b1ba ("Fix rmmod/read/write races in /proc entries"). Notice the chunk where inode->i_fop is initialized with proxy struct file_operations for regular files: - if (de->proc_fops) - inode->i_fop = de->proc_fops; + if (de->proc_fops) { + if (S_ISREG(inode->i_mode)) + inode->i_fop = &proc_reg_file_ops; + else + inode->i_fop = de->proc_fops; + } VFS stopped pinning module at this point. # ipvs Acked-by: Julian Anastasov Signed-off-by: Alexey Dobriyan Acked-by: Simon Horman Signed-off-by: Pablo Neira Ayuso --- net/netfilter/ipvs/ip_vs_app.c | 1 -
