2012-05-03cifs - check S_AUTOMOUNT in revalidateIan Kent
When revalidating a dentry, if the inode wasn't known to be a dfs entry when the dentry was instantiated, such as when created via ->readdir(), the DCACHE_NEED_AUTOMOUNT flag needs to be set on the dentry in ->d_revalidate(). The false return from cifs_d_revalidate(), due to the inode now being marked with the S_AUTOMOUNT flag, might not invalidate the dentry if there is a concurrent unlazy path walk. This is because the dentry reference count will be at least 2 in this case causing d_invalidate() to return EBUSY. So the asumption that the dentry will be discarded then correctly instantiated via ->lookup() might not hold.

Commit d902747("[libata] Add ATA transport class") introduced ATA_EFLAG_OLD_ER to mark entries in the error ring as cleared. But ata_count_probe_trials_cb() didn't check this flag and it still counts the old error history. So wrong probe trials count is returned and it causes problem, for example, SATA link speed is slowed down from 3.0Gbps to 1.5Gbps. Fix it by checking ATA_EFLAG_OLD_ER in ata_count_probe_trials_cb().

2012-05-03iwlwifi: fix skb truesize underestimationEric Dumazet
By default, iwlwifi uses order-1 pages (8 KB) to store incoming frames, but doesnt say so in skb->truesize. This makes very possible to exhaust kernel memory since these skb evade normal socket memory accounting. As struct ieee80211_hdr is going to be pulled before calling IP stack, there is no need to use dev_alloc_skb() to reserve NET_SKB_PAD bytes. alloc_skb() is ok in this driver, allowing more tailroom. Pull beginning of frame in skb header, in the hope we can reuse order-1 pages in the driver immediately for small frames and reduce their truesize to the minimum (linear skbs) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Cc: Wey-Yi Guy <wey-yi.w.guy@intel.com> Cc: "John W.

2012-05-02tcp: change tcp_adv_win_scale and tcp_rmem[2]Eric Dumazet
tcp_adv_win_scale default value is 2, meaning we expect a good citizen skb to have skb->len / skb->truesize ratio of 75% (3/4) In 2.6 kernels we (mis)accounted for typical MSS=1460 frame : 1536 + 64 + 256 = 1856 'estimated truesize', and 1856 * 3/4 = 1392. So these skbs were considered as not bloated. With recent truesize fixes, a typical MSS=1460 frame truesize is now the more precise : 2048 + 256 = 2304. But 2304 * 3/4 = 1728. So these skb are not good citizen anymore, because 1460 < 1728 (GRO can escape this problem because it build skbs with a too low truesize.) This also means tcp advertises a too optimistic window for a given allocated rcvspace : When receiving frames, sk_rmem_alloc can hit sk_rcvbuf limit and we call tcp_prune_queue()/tcp_collapse() too often, especially when application is slow to drain its receive queue or in case of losses (netperf is fast, scp is slow). This is a major latency source. We should adjust the len/truesize ratio to 50% instead of 75% This patch : 1) changes tcp_adv_win_scale default to 1 instead of 2 2) increase tcp_rmem[2] limit from 4MB to 6MB to take into account better truesize tracking and to allow autotuning tcp receive window to reach same value than before. Note that same amount of kernel memory is consumed compared to 2.6 kernels.

2012-05-02drop_monitor: prevent init path from scheduling on the wrong cpuNeil Horman
I just noticed after some recent updates, that the init path for the drop monitor protocol has a minor error. drop monitor maintains a per cpu structure, that gets initalized from a single cpu. Normally this is fine, as the protocol isn't in use yet, but I recently made a change that causes a failed skb allocation to reschedule itself . Given the current code, the implication is that this workqueue reschedule will take place on the wrong cpu. If drop monitor is used early during the boot process, its possible that two cpus will access a single per-cpu structure in parallel, possibly leading to data corruption. This patch fixes the situation, by storing the cpu number that a given instance of this per-cpu data should be accessed from. In the case of a need for a reschedule, the cpu stored in the struct is assigned the rescheule, rather than the currently executing cpu Tested successfully by myself.

This reverts commit a844adfd7bee4edc66d337de6c33b348e83552a8. The commit a844adfd is degrading rx sensitivity of lower rate in HT40 mode and it is confirmed that reverting the change is improving rx sensitivity. spur_freq_sd (for self-corr in AGC) is defined with respect to the center of each 20MHz channel while spur_phase_delta (for self-corr in Rx and spur data filter) is defined with respect to the center of current RF channel. So in short, we need to subtract spur_freq_sd (for self-corr in AGC) by the offset between the center of primary20 and the center of RF channel in SW. This offset could be +/10 MHz for dynamic 40.

2012-05-01cifs: don't cap ra_pages at the same level as default_backing_dev_infoJeff Layton
While testing, I've found that even when we are able to negotiate a much larger rsize with the server, on-the-wire reads often end up being capped at 128k because of ra_pages being capped at that level. Lifting this restriction gave almost a twofold increase in sequential read performance on my craptactular KVM test rig with a 1M rsize. I think this is safe since the actual ra_pages that the VM requests is run through max_sane_readahead() prior to submitting the I/O. Under memory pressure we should end up with large readahead requests being suppressed anyway. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
