net: Add missing annotation for llc_seq_start()

2020-02-24T21:26:49+00:00

Sparse reports a warning at llc_seq_start() warning: context imbalance in llc_seq_start() - wrong count at exit The root cause is the msiing annotation at llc_seq_start() Add the missing __acquires(RCU) annotation Signed-off-by: Jules Irenge Signed-off-by: David S. Miller

proc: introduce proc_create_seq{,_data}

2018-05-16T05:23:35+00:00

Variants of proc_create{,_data} that directly take a struct seq_operations argument and drastically reduces the boilerplate code in the callers. All trivial callers converted over. Signed-off-by: Christoph Hellwig

net: Use octal not symbolic permissions

2018-03-26T16:07:48+00:00

Prefer the direct use of octal for permissions. Done with checkpatch -f --types=SYMBOLIC_PERMS --fix-inplace and some typing. Miscellanea: o Whitespace neatening around these conversions. Signed-off-by: Joe Perches Signed-off-by: David S. Miller

net: delete /proc THIS_MODULE references

2018-01-16T20:01:33+00:00

/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.

sock: tigthen lockdep checks for sock_owned_by_user

2016-04-14T02:37:20+00:00

sock_owned_by_user should not be used without socket lock held. It seems to be a common practice to check .owned before lock reclassification, so provide a little help to abstract this check away.

net: proc_fs: trivial: print UIDs as unsigned int

2013-08-15T21:37:46+00:00

UIDs are printed in the proc_fs as signed int, whereas they are unsigned int. Signed-off-by: Francesco Fusco Signed-off-by: David S. Miller

net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules

2011-10-31T23:30:30+00:00

These files are non modular, but need to export symbols using the macros now living in export.h -- call out the include so that things won't break when we remove the implicit presence of module.h from everywhere. Signed-off-by: Paul Gortmaker

llc: replace the socket list with a local address based hash

2009-12-27T04:45:32+00:00

For the cases where a lot of interfaces are used in conjunction with a lot of LLC sockets bound to the same SAP, the iteration of the socket list becomes prohibitively expensive. Replacing the list with a a local address based hash significantly improves the bind and listener lookup operations as well as the datagram delivery. Connected sockets delivery is also improved, but this patch does not address the case where we have lots of sockets with the same local address connected to different remote addresses. In order to keep the socket sanity checks alive and fast a socket counter was added to the SAP structure. Signed-off-by: Octavian Purdila Signed-off-by: David S. Miller
