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.

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

ipv6: udp: remove udp_v6_clear_sk()

2016-08-24T06:23:50+00:00

Now RCU lookups of ipv6 udp sockets no longer dereference pinet6 field, we can get rid of udp_v6_clear_sk() 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

ipv6: do not clear pinet6 field

2013-05-11T23:26:38+00:00

We have seen multiple NULL dereferences in __inet6_lookup_established() After analysis, I found that inet6_sk() could be NULL while the check for sk_family == AF_INET6 was true. Bug was added in linux-2.6.29 when RCU lookups were introduced in UDP and TCP stacks. Once an IPv6 socket, using SLAB_DESTROY_BY_RCU is inserted in a hash table, we no longer can clear pinet6 field. This patch extends logic used in commit fcbdf09d9652c891 ("net: fix nulls list corruptions in sk_prot_alloc") TCP/UDP/UDPLite IPv6 protocols provide their own .clear_sk() method to make sure we do not clear pinet6 field. At socket clone phase, we do not really care, as cloning the parent (non NULL) pinet6 is not adding a fatal race. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

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.

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
