This untested patch _should_ fix: "(net de2104x) Kernel panic with de2104x tulip driver on boot" http://bugzilla.kernel.org/show_bug.cgi?id=3156 But the bug submitter isn't responding. Same fix has been applied to tulip.c (several years ago) and uli526x.c (Feb 2008) drivers. [ The panic reported in the bug report was removed in a recently (march 2008) accepted patch from Ondrej Zary. ] Signed-off-by:

This is a critical patch which adds a workaround for a HW bug. The patch will limit the number of outstanding tx packets to 16. Otherwise, the HW could send out packets with bad checksums. The driver will still setup the tx packets into the ring, however, will only set the Valid bit on 16 packets at a time. Signed-off-by:

The last change in the Tx queue stop mechanism opens a window where the Tx queue might be stopped after pending credits returned. Tx credits are returned via a control message generated by the HW. It returns tx credits on demand, triggered by a completion bit set in selective transmit packet headers. The current code can lead to the Tx queue stopped with all pending credits returned, and the current frame not triggering a credit return. The Tx queue will then never be awaken. The driver could alternatively request a completion for packets that stop the queue. It's however safer at this point to go back to the pre-existing behaviour. Signed-off-by:

This patch should resolve a problem that's troubled support for some RNDIS peripherals. It seems to have boiled down to using a variable to establish transfer size limits before it was assigned, which caused those devices to fallback to a default "jumbogram" mode we don't support. Fix by assigning it earlier for RNDIS. Signed-off-by:

Problem Description and Fix --------------------------- When a pause packet(with destination as reserved Multicast address) is received by the EMAC hardware to control the flow of frames being transmitted by it, it is dropped by the hardware unless the reserved Multicast address is hashed in to the GAHT[1-4] registers. This code fix adds the default reserved multicast address to the GAHT[1-4] registers in the EMAC(s) present on the chip. The flow control with Pause packets will only work if the following register bits are programmed in EMAC: EMACx_MR1[APP] = 1 EMACx_RMR[BAE] = 1 EMACx_RMR[MAE] = 1 Behavior that may be observed in a running system ------------------------------------------------- A host transferring data from a PPC based system may send a Pause packet to the PPC EMAC requesting it to slow down the flow of packets. If the default reserved multicast MAC address is not programmed into the GAHT[1-4] registers this Pause packet will be dropped by PPC EMAC and no Flow Control will be done. Signed-off-by:

Add suspend/resume handlers to rt2x00rfkill to have it stop the input-polldev and prevent it from calling rt2x00 during suspend period. This could lead to a NULL pointer fault when rt2x00 suspended, but polldev send a request, because the csr_addr is NULL. Also don't let the rfkill allocation/registration block the initialization of the entire device. Just print a warning and continue as if nothing happened. Signed-off-by:

The gelic driver uses two net interfaces, one for ethernet and the other for wireless. They share same MAC address and use 'eth' prefix for the name. As udev uses the MAC address to check uniqueness, this is somewhat problematic. So change the prefix of the network interface name for the wireless so that udev can have an easy way to distinguish interfaces. Signed-off-by:

Some implementations of the hidden SSID APs emit beacons which have the zero length SSID information element instead of SSID padded by null (\0) characters. If the firmware of the PS3 wireless hardware meets these beacons, it abandons parsing IEs. Thus guest OSes get the invalid scan information for the AP. To work around this, ignore these scan informations from the list. Signed-off-by:

Comparing with kernel 2.6.24, tbench result has regression with 2.6.25-rc1. 1) On 2 quad-core processor stoakley: 4%. 2) On 4 quad-core processor tigerton: more than 30%. bisect located below patch. b4ce9277 is first bad commit commit b4ce9277 Author: Herbert Xu <herbert@gondor.apana.org.au> Date: Tue Nov 13 21:33:32 2007 -0800 [IPV6]: Move nfheader_len into rt6_info The dst member nfheader_len is only used by IPv6. It's also currently creating a rather ugly alignment hole in struct dst. Therefore this patch moves it from there into struct rt6_info. Above patch changes the cache line alignment, especially member __refcnt. I did a testing by adding 2 unsigned long pading before lastuse, so the 3 members, lastuse/__refcnt/__use, are moved to next cache line. The performance is recovered. I created a patch to rearrange the members in struct dst_entry. With Eric and Valdis Kletnieks's suggestion, I made finer arrangement. 1) Move tclassid under ops in case CONFIG_NET_CLS_ROUTE=y. So sizeof(dst_entry)=200 no matter if CONFIG_NET_CLS_ROUTE=y/n. I tested many patches on my 16-core tigerton by moving tclassid to different place. It looks like tclassid could also have impact on performance. If moving tclassid before metrics, or just don't move tclassid, the performance isn't good. So I move it behind metrics. 2) Add comments before __refcnt. On 16-core tigerton: If CONFIG_NET_CLS_ROUTE=y, the result with below patch is about 18% better than the one without the patch; If CONFIG_NET_CLS_ROUTE=n, the result with below patch is about 30% better than the one without the patch. With 32bit 2.6.25-rc1 on 8-core stoakley, the new patch doesn't introduce regression. Thank Eric, Valdis, and David! Signed-off-by:

With TSO it was possible to send past the receiver window when the skb to be sent was the last in the write queue while the receiver window is the limiting factor. One can notice that there's a loophole in the tcp_mss_split_point that lacked a receiver window check for the tcp_write_queue_tail() if also cwnd was smaller than the full skb. Noticed by Thomas Gleixner <tglx@linutronix.de> in form of "Treason uncloaked! Peer ... shrinks window .... Repaired." messages (the peer didn't actually shrink its window as the message suggests, we had just sent something past it without a permission to do so). Signed-off-by:

Commit ce7663d8: [NETFILTER]: nfnetlink_queue: don't unregister handler of other subsystem changed nf_unregister_queue_handler to return an error when attempting to unregister a queue handler that is not identical to the one passed in. This is correct in case we really do have a different queue handler already registered, but some existing userspace code always does an unbind before bind and aborts if that fails, so try to be nice and return success in that case.

When binding or unbinding to an address family, the res_id is usually set to zero. When logging instance 0 already exists and is owned by a different process, this makes nfunl_recv_config return -EPERM without performing the bind operation. Since no operation on the foreign logging instance itself was requested, this is incorrect. Move bind/unbind commands before the queue instance permissions checks. Also remove an incorrect comment.
