2010-04-27bnx2: Prevent "scheduling while atomic" warning with cnic, bonding and vlan.Michael Chan1-18/+20
The bonding driver calls ndo_vlan_rx_register() while holding bond->lock. The bnx2 driver calls bnx2_netif_stop() to stop the rx handling while changing the vlgrp. The call also stops the cnic driver which sleeps while the bond->lock is held and cause the warning. This code path only needs to stop the NAPI rx handling while we are changing the vlgrp. Since no reset is going to occur, there is no need to stop cnic in this case. By adding a parameter to bnx2_netif_stop() to skip stopping cnic, we can avoid the warning.

2010-04-27bnx2: Fix lost MSI-X problem on 5709 NICs.Michael Chan1-1/+5
It has been reported that under certain heavy traffic conditions in MSI-X mode, the driver can lose an MSI-X vector causing all packets in the associated rx/tx ring pair to be dropped. The problem is caused by the chip dropping the write to unmask the MSI-X vector by the kernel (when migrating the IRQ for example). This can be prevented by increasing the GRC timeout value for these register read and write operations. Thanks to Dell for helping us debug this problem.

2010-04-27e1000e: enable/disable ASPM L0s and L1 and ERT according to hardware errataBruce Allan3-40/+55
Prompted by a previous patch submitted by Matthew Garret <mjg@redhat.com>, further digging into errata documentation reveals the current enabling or disabling of ASPM L0s and L1 states for certain parts supported by this driver are incorrect. 82571 and 82572 should always disable L1. For standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled, and for jumbo frames 82573/82574 must disable L1. This allows for some parts to enable L1 in certain configurations leading to better power savings. Also according to the same errata, Early Receive (ERT) should be disabled on 82573 when using jumbo frames.

2010-04-21net: ipv6 bind to device issueJiri Olsa1-1/+1
The issue raises when having 2 NICs both assigned the same IPv6 global address. If a sender binds to a particular NIC (SO_BINDTODEVICE), the outgoing traffic is being sent via the first found. The bonded device is thus not taken into an account during the routing. From the ip6_route_output function: If the binding address is multicast, linklocal or loopback, the RT6_LOOKUP_F_IFACE bit is set, but not for global address. So binding global address will neglect SO_BINDTODEVICE-binded device, because the fib6_rule_lookup function path won't check for the flowi::oif field and take first route that fits.

After receiving a ICMPv6 Too Big message reporting PMTU is less than the IPv6 Minimum Link MTU, sctp *can't* send any data/control chunk that total length including IPv6 head and IPv6 extend head is less than IPV6_MIN_MTU(1280 bytes).

Before commit e28cbf22933d0c0ccaf3c4c27a1a263b41f73859 ("improve sys_newuname() for compat architectures") 64-bit x86 had a private implementation of sys_uname which was just called sys_uname, which other architectures used for the old uname. Due to some merge issues with the uname refactoring patches we ended up calling the old uname version for both the old and new system call slots, which lead to the domainname filed never be set which caused failures with libnss_nis.

2010-04-19rmap: add exclusively owned pages to the newest anon_vmaRik van Riel1-11/+16
The recent anon_vma fixes cause many anonymous pages to end up in the parent process anon_vma, even when the page is exclusively owned by the current process. Adding exclusively owned anonymous pages to the top anon_vma reduces rmap scanning overhead, especially in workloads with forking servers. This patch adds a parameter to __page_set_anon_rmap that can be used to indicate whether or not the added page is exclusively owned by the current process. Pages added through page_add_new_anon_rmap are exclusively owned by the current process, and can be added to the top anon_vma. Pages added through page_add_anon_rmap can be either shared or exclusively owned, so we do the conservative thing and add it to the oldest anon_vma. A next step would be to add the exclusive parameter to page_add_anon_rmap, to be used from functions where we do know for sure whether a page is exclusively owned.

2010-04-19mac80211: pass HT changes to driver when off channelReinette Chatre1-0/+2
Since "mac80211: make off-channel work generic" drivers have not been notified of configuration changes after association or authentication. This caused more dependence on current state to ensure driver will be notified when configuration changes occur. One such problem arises if off-channel is in progress when HT information changes. Since HT is only enabled on the "oper_channel" the driver will never be notified of this change. Usually the driver is notified soon after of a BSS information change (BSS_CHANGED_HT) ... but since the driver did not get a notification that this is a HT channel the new BSS information does not make sense. Fix this by also changing the off-channel information when HT is enabled and thus cause driver to be notified correctly. This fixes a problem in 4965 when associated with 5GHz 40MHz channel. Without this patch the system can associate but is unable to transfer any data, not even ping.

2010-04-19mac80211: remove bogus TX agg state assignmentJohannes Berg1-1/+0
When the addba timer expires but has no work to do, it should not affect the state machine. If it does, TX will not see the successfully established and we can also crash trying to re-establish the session.

2010-04-19eCryptfs: Turn lower lookup error messages into debug messagesTyler Hicks1-6/+6
Vaugue warnings about ENAMETOOLONG errors when looking up an encrypted file name have caused many users to become concerned about their data. Since this is a rather harmless condition, I'm moving this warning to only be printed when the ecryptfs_verbosity module param is 1. Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
2010-04-19eCryptfs: Copy lower directory inode times and size on linkTyler Hicks1-2/+2
The timestamps and size of a lower inode involved in a link() call was being copied to the upper parent inode. Instead, we should be copying lower parent inode's timestamps and size to the upper parent inode. I discovered this bug using the POSIX test suite at Tuxera.
