Free the slot and resend the RPC with new session <slot#,seq#>.
For nfs4_async_handle_error, return -EAGAIN and set the task->tk_status to 0
to restart the async rpc in the rpc_restart_call_prepare state which resets
the slot.
For nfs4_handle_exception, retrying a call that uses nfs4_call_sync will
reset the slot via nfs41_call_sync_prepare.
For open/close/lock/locku/delegreturn/layoutcommit/unlink/rename/write
cachethis is true, so these operations will not trigger an
NFS4ERR_RETRY_UNCACHED_REP.

This reverts commit 4a5fa3590f09, which did not allow SLUB to be used
on architectures that use DISCONTIGMEM without compiling NUMA support
without CONFIG_BROKEN also set.
The slub panic that it was intended to prevent is addressed by
d9b41e0b54fd ("[PARISC] set memory ranges in N_NORMAL_MEMORY when
onlined") on parisc so there is no further slub issues with such a
configuration.
The reverts allows SLUB now to be used on such architectures since
there haven't been any reports of additional errors.

Like other mobile broadband device ethernet interfaces, mark the LG
VL600 with the 'wwan' devtype so userspace knows it needs additional
configuration via the AT port before the interface can be used.

Unlike the standard case, disabled anti replay detection needs some
nontrivial extra treatment on ESN. RFC 4303 states:
Note: If a receiver chooses to not enable anti-replay for an SA, then
the receiver SHOULD NOT negotiate ESN in an SA management protocol.
Use of ESN creates a need for the receiver to manage the anti-replay
window (in order to determine the correct value for the high-order
bits of the ESN, which are employed in the ICV computation), which is
generally contrary to the notion of disabling anti-replay for an SA.
So return an error if an ESN state with disabled anti replay detection
is inserted for now and add the extra treatment later if we need it.

As it is, we assign the outer modes output function to the dst entry
when we create the xfrm bundle. This leads to two problems on interfamily
scenarios. We might insert ipv4 packets into ip6_fragment when called
from xfrm6_output. The system crashes if we try to fragment an ipv4
packet with ip6_fragment. This issue was introduced with git commit
ad0081e4 (ipv6: Fragment locally generated tunnel-mode IPSec6 packets
as needed). The second issue is, that we might insert ipv4 packets in
netfilter6 and vice versa on interfamily scenarios.
With this patch we assign the inner mode output function to the dst entry
when we create the xfrm bundle. So xfrm4_output/xfrm6_output from the inner
mode is used and the right fragmentation and netfilter functions are called.
We switch then to outer mode with the output_finish functions.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs:
net/9p: Handle get_user_pages_fast return properly
|
|
After having applied commit 9954e7af14868b8b ("nilfs2: add free
entries count only if clear bit operation succeeded"), a free routine
of nilfs came to fall into an infinite loop, outputting the same
message endlessly:
nilfs_palloc_freev: entry number 29497 already freed
nilfs_palloc_freev: entry number 29497 already freed
nilfs_palloc_freev: entry number 29497 already freed
nilfs_palloc_freev: entry number 29497 already freed
nilfs_palloc_freev: entry number 29497 already freed ...
That patch broke the routine so that a loop counter is never updated
in an abnormal state. This fixes the regression.

This patch reverts a2361c8735e07322023aedc36e4938b35af31eb0:
"[PATCH] netfilter: xt_conntrack: warn about use in raw table"
Florian Wesphal says:
"... when the packet was sent from the local machine the skb
already has ->nfct attached, and -m conntrack seems to do
the right thing."

The mask indicates the bits one wants to zero out, so it needs to be
inverted before applying to the original TOS field.

The IPv6 header is not zeroed out in alloc_skb so we must initialize
it properly unless we want to see IPv6 packets with random TOS fields
floating around. The current implementation resets the flow label
but this could be changed if deemed necessary.
We stumbled upon this issue when trying to apply a mangle rule to
the RST packet generated by the REJECT target module.

DESCRIPTION
This patch tries to restore the initial init and cleanup
sequences that was before namspace patch.
Netns also requires action when net devices unregister
which has never been implemented. I.e this patch also
covers when a device moves into a network namespace,
and has to be released.
IMPLEMENTATION
The number of calls to register_pernet_device have been
reduced to one for the ip_vs.ko
Schedulers still have their own calls.
This patch adds a function __ip_vs_service_cleanup()
and an enable flag for the netfilter hooks.
The nf hooks will be enabled when the first service is loaded
and never disabled again, except when a namespace exit starts.

If the sync daemons run in a name space while it crashes
or get killed, there is no way to stop them except for a reboot.
When all patches are there, ip_vs_core will handle register_pernet_(),
i.e. ip_vs_sync_init() and ip_vs_sync_cleanup() will be removed.
Kernel threads should not increment the use count of a socket.
By calling sk_change_net() after creating a socket this is avoided.
sock_release cant be used intead sk_release_kernel() should be used.
Thanks Eric W Biederman for your advices.

The optimizations in commit 255d0dc34068a976
(netfilter: x_table: speedup compat operations) assume that
xt_compat_add_offset is called once per rule.
ebtables however called it for each match/target found in a rule.
The match/watcher/target parser already returns the needed delta, so it
is sufficient to move the xt_compat_add_offset call to a more reasonable
location.
While at it, also get rid of the unused COMPAT iterator macros.
