Tetsuo Handa <handat@pm.nttdata.co.jp> told me that connect(2) with TCPv6 socket almost always took a few minutes to return when we did not have any ports available in the range of net.ipv4.ip_local_port_range. The reason was that we used incorrect seed for calculating index of hash when we check established sockets in __inet6_check_established(). Signed-off-by:

Ingress queueing uses a seperate lock for serializing enqueue operations, but fails to properly protect itself against concurrent changes to the qdisc tree. Use queue_lock for now since the real fix it quite intrusive. Signed-off-by:

There are multiple problems related to qlen adjustment that can lead to an upper qdisc getting out of sync with the real number of packets queued, leading to endless dequeueing attempts by the upper layer code. All qdiscs must maintain an accurate q.qlen counter. There are basically two groups of operations affecting the qlen: operations that propagate down the tree (enqueue, dequeue, requeue, drop, reset) beginning at the root qdisc and operations only affecting a subtree or single qdisc (change, graft, delete class). Since qlen changes during operations from the second group don't propagate to ancestor qdiscs, their qlen values become desynchronized. This patch adds a function to propagate qlen changes up the qdisc tree, optionally calling a callback function to perform qdisc-internal maintenance when the child qdisc is deactivated, and converts all qdiscs to use this where necessary.

A serial card might have been removed when the system is resumed. This results in a suspended port being shut down, which results in the ports shutdown method being called twice in a row. This causes BUGs. Avoid this by tracking the suspended state separately from the initialised state. Signed-off-by:

When iterating through an array, one must be careful to test one's index variable rather than another similarly-named variable. The loop will read off the end of conf->disks[] in the following (pathological) case: % dd bs=1 seek=840716287 if=/dev/zero of=d1 count=1 % for i in 2 3 4; do dd if=/dev/zero of=d$i bs=1k count=$(($i+150)); done % ./vmlinux ubd0=root ubd1=d1 ubd2=d2 ubd3=d3 ubd4=d4 # mdadm -C /dev/md0 --level=linear --raid-devices=4 /dev/ubd[1234] adding some printks, I saw this: [42949374.960000] hash_spacing = 821120 [42949374.960000] cnt = 4 [42949374.960000] min_spacing = 801 [42949374.960000] j=0 size=820928 sz=820928 [42949374.960000] i=0 sz=820928 hash_spacing=820928 [42949374.960000] j=1 size=64 sz=64 [42949374.960000] j=2 size=64 sz=128 [42949374.960000] j=3 size=64 sz=192 [42949374.960000] j=4 size=1515870810 sz=1515871002 Signed-off-by: -

md raidX make_request functions strip off the BIO_RW_SYNC flag, thus introducing additional latency. Fixing this in raid1 and raid10 seems to be straightforward enough. For our particular usage case in DRBD, passing this flag improved some initialization time from ~5 minutes to ~5 seconds. Signed-off-by:

American Megatrends did something wrong in their floppy emulator. It breaks with both kinds of MODE SENSE which our stack sends. Alan and I tried a few tweaks, and got LUNs sensed right, but US_FL_NO_WP_DETECT is still needed. I set the firmware bracket to 1.00 exactly, in case AMI or Sun fix it with a firmware update. Hey, you never know. Signed-off-by:

Recently this entry's bcd scope was narrowed so as not to falsly apply to bcd's other than 0x0110. But while it breaks those of a larger bcd, it is still needed for those of a smaller bcd - so this changes the lower bcd limit to 0x0000. Signed-off-by:

The existing unusual_devs entry for the UCR-61S2B appears to have too wide a revision range. It matches at least one device that doesn't respond to the initialization sequence. Perhaps the sequence needs to be updated, or perhaps something else can be done. For now, this patch (as764) restricts the range to include only the revision mentioned in the original comment. This resolves (for now!) Bugzilla entry #6950. Signed-off-by:

The mass storage device from Digitech designed for Flash Cards, as found on (for example) the GNX4 device has issues with residue, similar to the bug report at http://kerneltrap.org/node/6297. This patch adds the faulty storage device to unusual_devs.h, this not only reduces the noise in dmesg but also increases the transfer speeds by a factor of 7x for me (89kB/s -> 637kB/s).
