Early versions of the SFX7101 firmware could complete link training in a state where it would not adequately cancel noise (Solarflare bug 10750). We previously worked around this by resetting the PHY after seeing many Ethernet CRC errors. This workaround is unsafe since it takes no account of the interval between errors; it also appears to be unnecessary with production firmware. Therefore remove it.

commit 0f0ca340 ("phy: power management support") caused a regression in the gianfar driver. Now phylib turns off PHY power during suspend, and thus WOL doesn't work anymore. This patch workarounds the issue by enabling wakeup in the MDIO device, i.e. just restores the old behaviour for the gianfar driver. Note that this way all PHYs on a given MDIO bus won't be turned off during suspend, which isn't good from the power saving point of view. A proper, per netdevice wakeup management support will need a bit reworked phylib suspend/resume logic. Signed-off-by: NAnton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: NDavid S.

smsc9420 performs an interrupt signalling test when the interface is brought up. The current code mistakenly sets its test flag to false AFTER enabling the software interrupt source, making failure quite likely. This patch changes the code to set the test flag BEFORE enabling interrupts. I've also removed an smp_wmb because the following spinlock provides an implicit memory barrier.

The commit b31a1d8b ("gianfar: Convert gianfar to an of_platform_driver") changes the gianfar's phy id to the format like "mdio@xxxx:xx", but uec still uses the old format like "xxxxxxxx:xx". For the board whose UEC uses gianfar-mdio like MPC8568MDS, the phy can not be attached because of the incompatible phy id format. This patch changes uec's phy id to the same format as gianfar's.

As reported by Toralf Förster and Randy Dunlap. - http://linuxwimax.org/pipermail/wimax/2009-January/000460.html - http://lkml.org/lkml/2009/1/29/279 The definitions needed for the wimax stack and i2400m driver debug infrastructure was, by mistake, compiled depending on CONFIG_DEBUG_FS (by them being placed in the debugfs.c files); thus the build broke in 2.6.29-rc3 when debugging was enabled (CONFIG_WIMAX_DEBUG) and DEBUG_FS was disabled. These definitions are always needed if debug is enabled at compile time (independently of DEBUG_FS being or not enabled), so moving them to a file that is always compiled fixes the issue.

It oopsd for me in skb_seq_read. addr2line said it was linux-2.6/net/core/skbuff.c:2228, which is this line: while (st->frag_idx < skb_shinfo(st->cur_skb)->nr_frags) { I added some printks in there and it looks like we hit this: } else if (st->root_skb == st->cur_skb && skb_shinfo(st->root_skb)->frag_list) { st->cur_skb = skb_shinfo(st->root_skb)->frag_list; st->frag_idx = 0; goto next_skb; } Actually I did some testing and added a few printks and found that the st->cur_skb->data was 0 and hence the ptr used by iscsi_tcp was null. This caused the kernel panic. if (abs_offset < block_limit) { - *data = st->cur_skb->data + abs_offset; + *data = st->cur_skb->data + (abs_offset - st->stepped_offset); I enabled the debug_tcp and with a few printks found that the code did not go to the next_skb label and could find that the sequence being followed was this - It hit this if condition - if (st->cur_skb->next) { st->cur_skb = st->cur_skb->next; st->frag_idx = 0; goto next_skb; And so, now the st pointer is shifted to the next skb whereas actually it should have hit the second else if first since the data is in the frag_list. else if (st->root_skb == st->cur_skb && skb_shinfo(st->root_skb)->frag_list) { st->cur_skb = skb_shinfo(st->root_skb)->frag_list; goto next_skb; } Reversing the two conditions the attached patch fixes the issue for me on top of Herbert's patches.

Reducing jumbo ring size below 1024 reduces throughput for old firmwares (3.4.216 and older) running on older (NX2031) chip, so restore it back to 1024. This was reduced in commit 32ec8033 ("netxen: reduce memory footprint"). Raising jumbo ring size from 512 to 1024, adds ~4MB per port, but there's still big saving because of original patch (~20MB per port).

After reports of poor performance, a review of the latest vendor driver (rtl8187_linux_26.1025.0328.2007) for RTL8187L devices was undertaken. A difference was found in the code used to index the OFDM power tables. When the Linux driver was changed, my unit works at a much greater range than before.

This patch addresses the IPv6 multicast routing issues described below. It was tested with XORP 1.4/1.5 as the IPv6 PIM-SM routing daemon against FreeBSD peers. net/ipv6/ip6_input.c: - Don't try to forward link-local multicast packets. - Don't reset skb2->dev before calling ip6_mr_input() so packets can be identified as coming from the PIM register vif properly. net/ipv6/ip6mr.c: - Fix incoming PIM register messages processing: * The IPv6 pseudo-header should be included when checksumming PIM messages (RFC 4601 section 4.9; RFC 3973 section 4.7.1). * Packets decapsulated from PIM register messages should have skb->protocol ETH_P_IPV6. - Enable/disable IPv6 multicast forwarding on the corresponding interface when a routing daemon adds/removes a multicast virtual interface. - Remove incorrect skb_pull() to fix userspace signaling. - Enable/disable global IPv6 multicast forwarding when an IPv6 multicast routing socket is opened/closed. net/ipv6/route.c: - Don't use strict routing logic for packets decapsulated from PIM register messages (similar to disabling rp_filter for the IPv4 case).

In commit 9db66bdc (net: convert TCP/DCCP ehash rwlocks to spinlocks), I forgot to change one occurrence of rwlock_t to spinlock_t I believe sizeof(raw_spinlock_t) might be > 0 on !CONFIG_SMP if CONFIG_DEBUG_SPINLOCK while sizeof(raw_rwlock_t) should be 0 in this case. Fortunatly, CONFIG_DEBUG_SPINLOCK adds fields to both spinlock_t and rwlock_t, but at this might change in the future (being able to debug spinlocks but not rwlocks for example), better to be safe.

tcp_splice_data_recv has two lengths to consider: the len parameter it gets from tcp_read_sock, which specifies the amount of data in the skb, and rd_desc->count, which is the amount of data the splice caller still wants. Currently it passes just the latter to skb_splice_bits, which then splices min(rd_desc->count, skb->len - offset) bytes. Most of the time this is fine, except when the skb contains urgent data. In that case len goes only up to the urgent byte and is less than skb->len - offset. By ignoring len tcp_splice_data_recv may a) splice data tcp_read_sock told it not to, b) return to tcp_read_sock a value > len. Now, tcp_read_sock doesn't handle used > len and leaves the socket in a bad state (both sk_receive_queue and copied_seq are bad at that point) resulting in duplicated data and corruption. Fix by passing min(rd_desc->count, len) to skb_splice_bits. Signed-off-by: NDimitris Michailidis <dm@chelsio.com> Acked-by: NEric Dumazet <dada1@cosmosbay.com> Signed-off-by: NDavid S.

commit 9088c560 (udp: Improve port randomization) introduced a regression for UDP bind() syscall to null port (getting a random port) in case lot of ports are already in use. This is because we do about 28000 scans of very long chains (220 sockets per chain), with many spin_lock_bh()/spin_unlock_bh() calls. Fix this using a bitmap (64 bytes for current value of UDP_HTABLE_SIZE) so that we scan chains at most once. Instead of 250 ms per bind() call, we get after patch a time of 2.9 ms Based on a report from Vitaly Mayatskikh Reported-by: NVitaly Mayatskikh <v.mayatskih@gmail.com> Signed-off-by: NEric Dumazet <dada1@cosmosbay.com> Tested-by: NVitaly Mayatskikh <v.mayatskih@gmail.com> Signed-off-by: NDavid S.
