16 years agouli526x: add support for netpoll
Anton Vorontsov [Fri, 16 May 2008 19:04:51 +0000 (23:04 +0400)]
uli526x: add support for netpoll

This patch adds netpoll support for the uli526x ethernet driver --
simply call the interrupt handler for polling.

To do this without disable_irq()/enable_irq() pair we should fully
protect the handler. Luckily, it's already using irqsave spinlock,
the only unprotected place is interrupts re-enabling write. It was
safe to re-enable interrupts without holding the spinlock, but with
netpoll possibility now it doesn't seem so.

Patch was tested using netconsole and KGDBoE.

[SC92031] Using padto turned driver into an IPv6-only interface

IPv4 would work with this driver only with static arp table entries,
the patch  reverts a padto introduced in

 commit 26a17b7bbb36a8552d531bc1ad08472fb5aa3007
 sc92031: start transmit return value bugfix

The padto does not work because the driver code evaluates `len' later on and
there are cases where skb->len is not updated accordingly.

This was observed with ARP frames (skb->len = 42 bytes, !skb_cloned(),
skb_tailroom = 84 bytes). Then in skb_pad(), the first condition is true, where
skb->len is not updated. As a consequence, the driver uses 42 bytes instead of
the 60 bytes, and the ARP frame never makes it onto the wire.

cassini: Only use chip checksum for ipv4 packets.

According to David Monro, at least with Natsemi Saturn chips the
cassini driver has some trouble with ipv6 checksums.

Until we have more information about what's going on here, only
use the chip checksums for ipv4.

This workaround was suggested and tested by David.

16 years agotcp: TCP connection times out if ICMP frag needed is delayed
Sridhar Samudrala [Wed, 21 May 2008 23:42:20 +0000 (16:42 -0700)]
tcp: TCP connection times out if ICMP frag needed is delayed

We are seeing an issue with TCP in handling an ICMP frag needed
message that is received after net.ipv4.tcp_retries1 retransmits.
The default value of retries1 is 3. So if the path mtu changes
and ICMP frag needed is lost for the first 3 retransmits or if
it gets delayed until 3 retransmits are done, TCP doesn't update
MSS correctly and continues to retransmit the orginal message
until it timesout after tcp_retries2 retransmits.

I am seeing this issue even with the latest 2.6.25.4 kernel.

In tcp_retransmit_timer(), when retransmits counter exceeds
tcp_retries1 value, the dst cache entry of the socket is reset.
At this time, if we receive an ICMP frag needed message, the
dst entry gets updated with the new MTU, but the TCP sockets
dst_cache entry remains NULL.

So the next time when we try to retransmit after the ICMP frag
needed is received, tcp_retransmit_skb() gets called. Here the
cur_mss value is calculated at the start of the routine with
a NULL sk_dst_cache. Instead we should call tcp_current_mss after
the rebuild_header that caches the dst entry with the updated mtu.
Also the rebuild_header should be called before tcp_fragment
so that skb is fragmented if the mss goes down.
