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.

udplite: fix NULL pointer dereference

2016-11-15T16:59:38+00:00

The commit 850cbaddb52d ("udp: use it's own memory accounting schema") assumes that the socket proto has memory accounting enabled, but this is not the case for UDPLITE. Fix it enabling memory accounting for UDPLITE and performing fwd allocated memory reclaiming on socket shutdown. UDP and UDPLITE share now the same memory accounting limits. Also drop the backlog receive operation, since is no more needed. Fixes: 850cbaddb52d ("udp: use it's own memory accounting schema") Reported-by: Andrei Vagin Suggested-by: Eric Dumazet Signed-off-by: Paolo Abeni Signed-off-by: David S. Miller

udp: get rid of sk_prot_clear_portaddr_nulls()

2016-08-24T06:25:29+00:00

Since we no longer use SLAB_DESTROY_BY_RCU for UDP, we do not need sk_prot_clear_portaddr_nulls() helper. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

udp: get rid of SLAB_DESTROY_BY_RCU allocations

2016-08-24T00:46:17+00:00

After commit ca065d0cf80f ("udp: no longer use SLAB_DESTROY_BY_RCU") we do not need this special allocation mode anymore, even if it is harmless. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net: Eliminate no_check from protosw

2014-05-23T20:28:53+00:00

It doesn't seem like an protocols are setting anything other than the default, and allowing to arbitrarily disable checksums for a whole protocol seems dangerous. This can be done on a per socket basis. Signed-off-by: Tom Herbert Signed-off-by: David S. Miller

net: ipv4: Standardize prefixes for message logging

2012-03-13T00:05:21+00:00

Add #define pr_fmt(fmt) as appropriate. Add "IPv4: ", "TCP: ", and "IPsec: " to appropriate files. Standardize on "UDPLite: " for appropriate uses. Some prefixes were previously "UDPLITE: " and "UDP-Lite: ". Add KBUILD_MODNAME ": " to icmp and gre. Remove embedded prefixes as appropriate. Add missing "\n" to pr_info in gre.c.

net: Convert printks to pr_

2012-03-12T06:42:51+00:00

Use a more current kernel messaging style. Convert a printk block to print_hex_dump. Coalesce formats, align arguments. Use %s, __func__ instead of embedding function names. Some messages that were prefixed with _close are now prefixed with _fini. Some ah4 and esp messages are now not prefixed with "ip ". The intent of this patch is to later add something like #define pr_fmt(fmt) "IPv4: " fmt. to standardize the output messages. Text size is trivially reduced.

net: make the tcp and udp file_operations for the /proc stuff const

2011-11-01T21:56:14+00:00

the tcp and udp code creates a set of struct file_operations at runtime while it can also be done at compile time, with the added benefit of then having these file operations be const. the trickiest part was to get the "THIS_MODULE" reference right; the naive method of declaring a struct in the place of registration would not work for this reason.
