> What about the RXD3/TXD3 pins?

You're right - I got the IOMUX tables wrong and thought UART0 pins are
selected unconditionally. But as it turns out TXD1/RXD1 is for UART0
(mxc_uart_device0), TXD2/RXD2 for UART1 (mxc_uart_device1) etc.

Below is a new patch.

Thanks,
Daniel

cls_cgroup_classify() when we use cls_cgroup.

When we execute 'tc filter add', tcf_proto is allocated, initialized

tc_ctl_tfilter() calls classifier's change().  When classifier's
change() fails, tc_ctl_tfilter() does not free and keeps tcf_proto.

In addition, cls_cgroup is initialized in change() not in init().  It
accesses unconfigured struct tcf_proto which is chained before
change(), then hits Oops.

11 years agoe1000: add missing length check to e1000 receive routine
Neil Horman [Tue, 2 Jun 2009 08:29:58 +0000 (01:29 -0700)]
e1000: add missing length check to e1000 receive routine

Patch to fix bad length checking in e1000.  E1000 by default does two
things:

1) Spans rx descriptors for packets that don't fit into 1 skb on recieve
2) Strips the crc from a frame by subtracting 4 bytes from the length prior to
doing an skb_put

Since the e1000 driver isn't written to support receiving packets that span
multiple rx buffers, it checks the End of Packet bit of every frame, and
discards it if its not set.  This places us in a situation where, if we have a
spanning packet, the first part is discarded, but the second part is not (since
it is the end of packet, and it passes the EOP bit test).  If the second part of
the frame is small (4 bytes or less), we subtract 4 from it to remove its crc,
underflow the length, and wind up in skb_over_panic, when we try to skb_put a
huge number of bytes into the skb.  This amounts to a remote DOS attack through
careful selection of frame size in relation to interface MTU.  The fix for this
is already in the e1000e driver, as well as the e1000 sourceforge driver, but no
one ever pushed it to e1000.  This is lifted straight from e1000e, and prevents
small frames from causing the underflow described above
