2010-06-18e1000e: fix check for manageability on ICHx/PCHBruce Allan
Do not check for all the bits in E1000_FWSM_MODE_MASK when checking for manageability on 82577/82578; only check if iAMT is enabled. Both of the manageability checks (for 82577/82578 and ICHx) must check the firmware valid bit too since the other bits are only valid when the latter is set.

2010-06-18e1000e: separate out PHY statistics register updatesBruce Allan
The 82577/82578 parts have half-duplex statistics in PHY registers. These need only be read when in half-duplex and should all be read at once rather than one at a time to prevent excessive cycles of acquiring/releasing the PHY semaphore.

2010-06-17bnx2: fix dma_get_ops compilation breakageFUJITA Tomonori
This removes dma_get_ops() prefetch optimization in bnx2. bnx2 uses dma_get_ops() to see if dma_sync_single_for_cpu() is noop. bnx2 does prefetch if it's noop. But dma_get_ops() isn't available on all the architectures (only the architectures that uses dma_map_ops struct have it). Using dma_get_ops() in drivers leads to compilation breakage on many architectures. This patch removes dma_get_ops() and changes bnx2 to do prefetch on all the architectures. This adds useless prefetch on non-coherent architectures but this is harmless. It is also unlikely to cause the performance drop.

This situation confuses the driver, and so the skb_put() sanity check fails. This patch fixes the issue by adding an appropriate check, i.e. the driver should not try to process frames with buffer descriptor's length over rx_buffer_size (i.e. maxfrm and mrblr). Note that sometimes eTSEC works correctly, i.e. in the second (last) buffer descriptor bits 'truncated' and 'crcerr' are set, and so there's no oops.

2010-06-16af_unix: Allow connecting to sockets in other network namespaces.Eric W. Biederman
Remove the restriction that only allows connecting to a unix domain socket identified by unix path that is in the same network namespace. Crossing network namespaces is always tricky and we did not support this at first, because of a strict policy of don't mix the namespaces. Later after Pavel proposed this we did not support this because no one had performed the audit to make certain using unix domain sockets across namespaces is safe. What fundamentally makes connecting to af_unix sockets in other namespaces is safe is that you have to have the proper permissions on the unix domain socket inode that lives in the filesystem. If you want strict isolation you just don't create inodes where unfriendlys can get at them, or with permissions that allow unfriendlys to open them. All nicely handled for us by the mount namespace and other standard file system facilities. I looked through unix domain sockets and they are a very controlled environment so none of the work that goes on in dev_forward_skb to make crossing namespaces safe appears needed, we are not loosing controll of the skb and so do not need to set up the skb to look like it is comming in fresh from the outside world. Further the fields in struct unix_skb_parms should not have any problems crossing network namespaces. Now that we handle SCM_CREDENTIALS in a way that gives useable values across namespaces. There does not appear to be any operational problems with encouraging the use of unix domain sockets across containers either. Signed-off-by: Eric W.

Effectively the situation is the same, we want to return a uid or gid that is not assigned to any user. - For the case when we happen to be mapping the uid or gid of the creator of the target user namespace use uid 0 and gid as confusing that user with root is not a problem.

2010-06-16Clear IFF_XMIT_DST_RELEASE for teql interfacesTom Hughes
https://bugzilla.kernel.org/show_bug.cgi?id=16183 The sch_teql module, which can be used to load balance over a set of underlying interfaces, stopped working after 2.6.30 and has been broken in all kernels since then for any underlying interface which requires the addition of link level headers. The problem is that the transmit routine relies on being able to access the destination address in the skb in order to do address resolution once it has decided which underlying interface it is going to transmit through. In 2.6.31 the IFF_XMIT_DST_RELEASE flag was introduced, and set by default for all interfaces, which causes the destination address to be released before the transmit routine for the interface is called. The solution is to clear that flag for teql interfaces. Signed-off-by: Tom Hughes <tom@compton.nu> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Discard the ACK if we find options that do not match current sysctl settings. Previously it was possible to create a connection with sack, wscale, etc. enabled even if the feature was disabled via sysctl. Also remove an unneeded call to tcp_sack_reset() in cookie_check_timestamp: Both call sites (cookie_v4_check, cookie_v6_check) zero "struct tcp_options_received", hand it to tcp_parse_options() (which does not change tcp_opt->num_sacks/dsack) and then call cookie_check_timestamp(). Even if num_sacks/dsacks were changed, the structure is allocated on the stack and after cookie_check_timestamp returns only a few selected members are copied to the inet_request_sock.

2010-06-16gianfar: Fix setup of RX time stampingManfred Rudigier
Previously the RCTRL_TS_ENABLE bit was set unconditionally. However, if the RCTRL_TS_ENABLE is set without TMR_CTRL[TE], the driver does not work properly on some boards (Anton had problems with the MPC8313ERDB and MPC8568EMDS). With this patch the bit will only be set if requested from user space with the SIOCSHWTSTAMP ioctl command, meaning that time stamping is disabled during normal operation. Users who are not interested in time stamps will not experience problems with buggy CPU revisions or performance drops any more. The setting of TMR_CTRL[TE] is still up to the user. This is considered safe because users wanting HW timestamps must initialize the eTSEC clock first anyway, e.g. with the recently submitted PTP clock driver.

2010-06-16ath5k: review RX descriptor functionsBruno Randolf
Reviewed RX descriptor functions against the HAL sources. Some minor changes: - check size before making changes to the descriptor - whitespace - add comments about 5210 timestamps. this needs to be adressed later! - FIFO overrun error only available on 5210 - rs_phyerr should not be OR'ed - clear the whole ath5k_rx_status structure before using, instead of zeroing specific fields.
