Subject: [v3.3-rc1 regression] TCP: too many of orphaned sockets
Date: Fri, 27 Jan 2012 13:46:41 +0100 [thread overview]
Message-ID: <20120127124641.GA30819@elte.hu> (raw)

There's a new TCP regression in latest -git that triggers in
randconfig testing.
With the attached config i'm getting tons of these messages:
[ 32.751209] TCP: too many of orphaned sockets
[ 37.198307] TCP: too many of orphaned sockets
[ 42.464404] TCP: too many of orphaned sockets
[ 48.920392] TCP: too many of orphaned sockets
[ 56.370026] TCP: too many of orphaned sockets
[ 64.605937] TCP: too many of orphaned sockets
and it's not possible to ssh into the testbox, the TCP
connection hangs.
Before i put more effort into debugging this, is this bug
already known/fixed?
NOTE: the .config is randconfig generated so it might have a few
weird combinations of config options. One such thing i noticed
is !CONFIG_BUG, this produces at least one of the following
build warnings in the networking code:
net/core/ethtool.c:211:1: warning: control reaches end of non-void function [-Wreturn-type]
net/core/dev.c:1892:33: warning: unused variable ‘null_features’ [-Wunused-variable]
net/packet/af_packet.c:1878:30: warning: ‘hdrlen’ may be used uninitialized in this function [-Wmaybe-uninitialized]
net/xfrm/xfrm_policy.c:2456:17: warning: ‘xfrm_dst_ops’ may be used uninitialized in this function [-Wmaybe-uninitialized]
net/xfrm/xfrm_policy.c:1351:7: warning: ‘dst_ops’ may be used uninitialized in this function [-Wmaybe-uninitialized]
net/xfrm/xfrm_policy.c:1333:18: note: ‘dst_ops’ was declared here
net/xfrm/xfrm_policy.c:1351:7: warning: ‘dst_ops’ may be used uninitialized in this function [-Wmaybe-uninitialized]
net/xfrm/xfrm_policy.c:1333:18: note: ‘dst_ops’ was declared here
Note#2, the message should probably be fixed as well:
- TCP: too many of orphaned sockets
+ TCP: too many orphaned sockets
Thanks,
Ingo
