      [NET]: Make the device list and device lookups per namespace. · 881d966b
      由 Eric W. Biederman 提交于 
      This patch makes most of the generic device layer network
namespace safe.  This patch makes dev_base_head a
network namespace variable, and then it picks up
a few associated variables.  The functions:
dev_getbyhwaddr
dev_getfirsthwbytype
dev_get_by_flags
dev_get_by_name
__dev_get_by_name
dev_get_by_index
__dev_get_by_index
dev_ioctl
dev_ethtool
dev_load
wireless_process_ioctl

were modified to take a network namespace argument, and
deal with it.

vlan_ioctl_set and brioctl_set were modified so their
hooks will receive a network namespace argument.

So basically anthing in the core of the network stack that was
affected to by the change of dev_base was modified to handle
multiple network namespaces.  The rest of the network stack was
simply modified to explicitly use &init_net the initial network
namespace.  This can be fixed when those components of the network
stack are modified to handle multiple network namespaces.

For now the ifindex generator is left global.

Fundametally ifindex numbers are per namespace, or else
we will have corner case problems with migration when
we get that far.

At the same time there are assumptions in the network stack
that the ifindex of a network device won't change.  Making
the ifindex number global seems a good compromise until
the network stack can cope with ifindex changes when
you change namespaces, and the like.

      [NET]: Make socket creation namespace safe. · 1b8d7ae4
      由 Eric W. Biederman 提交于 
      This patch passes in the namespace a new socket should be created in
and has the socket code do the appropriate reference counting.  By
virtue of this all socket create methods are touched.  In addition
the socket create methods are modified so that they will fail if
you attempt to create a socket in a non-default network namespace.

Failing if we attempt to create a socket outside of the default
network namespace ensures that as we incrementally make the network stack
network namespace aware we will not export functionality that someone
has not audited and made certain is network namespace safe.
Allowing us to partially enable network namespaces before all of the
exotic protocols are supported.

Any protocol layers I have missed will fail to compile because I now
pass an extra parameter into the socket creation code.

      [NET]: Make /proc/net per network namespace · 457c4cbc
      由 Eric W. Biederman 提交于 
      This patch makes /proc/net per network namespace.  It modifies the global
variables proc_net and proc_net_stat to be per network namespace.
The proc_net file helpers are modified to take a network namespace argument,
and all of their callers are fixed to pass &init_net for that argument.
This ensures that all of the /proc/net files are only visible and
usable in the initial network namespace until the code behind them
has been updated to be handle multiple network namespaces.

Making /proc/net per namespace is necessary as at least some files
in /proc/net depend upon the set of network devices which is per
network namespace, and even more files in /proc/net have contents
that are relevant to a single network namespace.

      [NET]: Change type of owner in sock_lock_t to int, rename · d2e9117c
      由 John Heffner 提交于 
      The type of owner in sock_lock_t is currently (struct sock_iocb *),
presumably for historical reasons.  It is never used as this type, only
tested as NULL or set to (void *)1.  For clarity, this changes it to type
int, and renames to owned, to avoid any possible type casting errors.

      [NET]: Fix two issues wrt. SO_BINDTODEVICE. · 4878809f
      由 David S. Miller 提交于 
      1) Comments suggest that setting optlen to zero will unbind
   the socket from whatever device it might be attached to.  This
   hasn't been the case since at least 2.2.x because the first thing
   this function does is return -EINVAL if 'optlen' is less than
   sizeof(int).

   This check also means that passing in a two byte string doesn't
   work so well.  It's almost as if this code was testing with "eth?"
   patterned strings and nothing else :-)

   Fix this by breaking the logic of this facility out into a
   seperate function which validates optlen more appropriately.

   The optlen==0 and small string cases now work properly.

2) We should reset the cached route of the socket after we have made
   the device binding changes, not before.

      [NET] gso: Fix GSO feature mask in sk_setup_caps · 4fcd6b99
      由 Herbert Xu 提交于 
      This isn't a bug just yet as only TCP uses sk_setup_caps for GSO.
However, if and when UDP or something else starts using it this is
likely to cause a problem if we forget to add software emulation
for it at the same time.

The problem is that right now we translate GSO emulation to the
bitmask NETIF_F_GSO_MASK, which includes every protocol, even
ones that we cannot emulate.

This patch makes it provide only the ones that we can emulate.

      [NET]: "wrong timeout value" in sk_wait_data() v2 · ba78073e
      由 Vasily Averin 提交于 
      sys_setsockopt() do not check properly timeout values for
SO_RCVTIMEO/SO_SNDTIMEO, for example it's possible to set negative timeout
values. POSIX do not defines behaviour for sys_setsockopt in case negative
timeouts, but requires that setsockopt() shall fail with -EDOM if the send and
receive timeout values are too big to fit into the timeout fields in the socket
structure.
In current implementation negative timeout can lead to error messages like
"schedule_timeout: wrong timeout value".

Proposed patch:
- checks tv_usec and returns -EDOM if it is wrong
- do not allows to set negative timeout values (sets 0 instead) and outputs
ratelimited information message about such attempts.
