42324c6 Eric Dumazet 01 October 2009, 22:26:00 UTC net: splice() from tcp to pipe should take into account O_NONBLOCK tcp_splice_read() doesnt take into account socket's O_NONBLOCK flag Before this patch : splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE); causes a random endless block (if pipe is full) and splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE | SPLICE_F_NONBLOCK); will return 0 immediately if the TCP buffer is empty. User application has no way to instruct splice() that socket should be in blocking mode but pipe in nonblock more. Many projects cannot use splice(tcp -> pipe) because of this flaw. http://git.samba.org/?p=samba.git;a=history;f=source3/lib/recvfile.c;h=ea0159642137390a0f7e57a123684e6e63e47581;hb=HEAD http://lkml.indiana.edu/hypermail/linux/kernel/0807.2/0687.html Linus introduced SPLICE_F_NONBLOCK in commit 29e350944fdc2dfca102500790d8ad6d6ff4f69d (splice: add SPLICE_F_NONBLOCK flag ) It doesn't make the splice itself necessarily nonblocking (because the actual file descriptors that are spliced from/to may block unless they have the O_NONBLOCK flag set), but it makes the splice pipe operations nonblocking. Linus intention was clear : let SPLICE_F_NONBLOCK control the splice pipe mode only This patch instruct tcp_splice_read() to use the underlying file O_NONBLOCK flag, as other socket operations do. Users will then call : splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE | SPLICE_F_NONBLOCK ); to block on data coming from socket (if file is in blocking mode), and not block on pipe output (to avoid deadlock) First version of this patch was submitted by Octavian Purdila Reported-by: Volker Lendecke <vl@samba.org> Reported-by: Jason Gunthorpe <jgunthorpe@obsidianresearch.com> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: Octavian Purdila <opurdila@ixiacom.com> Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Acked-by: Jens Axboe <jens.axboe@oracle.com> Signed-off-by: David S.

914a9ab Atis Elsts 01 October 2009, 22:16:49 UTC net: Use sk_mark for routing lookup in more places This patch against v2.6.31 adds support for route lookup using sk_mark in some more places. The benefits from this patch are the following. First, SO_MARK option now has effect on UDP sockets too. Second, ip_queue_xmit() and inet_sk_rebuild_header() could fail to do routing lookup correctly if TCP sockets with SO_MARK were used.

6646679 Stephen Hemminger 01 October 2009, 07:11:46 UTC sky2: irqname based on pci address This is based on Michal Schmidt fix for skge. Most network drivers request their IRQ when the interface is activated. sky2 does it in ->probe() instead, because it can work with two-port cards where the two net_devices use the same IRQ. This works fine most of the time, except in some situations when the interface gets renamed. Consider this example: 1. modprobe sky2 The card is detected as eth0 and requests IRQ 17. Directory /proc/irq/17/eth0 is created. 2. There is an udev rule which says this interface should be called eth1, so udev renames eth0 -> eth1. 3. modprobe 8139too The Realtek card is detected as eth0. It will be using IRQ 17 too. 4. ip link set eth0 up Now 8139too requests IRQ 17. The result is: WARNING: at fs/proc/generic.c:590 proc_register ... proc_dir_entry '17/eth0' already registered The fix is for sky2 to name the irq based on the pci device, as is done by some other devices DRM, infiniband, ... ie. sky2@pci:0000:00:00 Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Reviewed-by: Michal Schmidt <mschmidt@redhat.com> Signed-off-by: David S.

415e69e Michal Schmidt 01 October 2009, 08:13:23 UTC skge: use unique IRQ name Most network drivers request their IRQ when the interface is activated. skge does it in ->probe() instead, because it can work with two-port cards where the two net_devices use the same IRQ. This works fine most of the time, except in some situations when the interface gets renamed. Consider this example: 1. modprobe skge The card is detected as eth0 and requests IRQ 17. Directory /proc/irq/17/eth0 is created. 2. There is an udev rule which says this interface should be called eth1, so udev renames eth0 -> eth1. 3. modprobe 8139too The Realtek card is detected as eth0.

And "ls /proc/irq/17" shows two subdirectories, both called eth0. Fix it by using a unique name for skge's IRQ, based on the PCI address. The naming from the example then looks like this: $ grep skge /proc/interrupts 17: 169 IO-APIC-fasteoi skge@pci:0000:00:0a.0, eth0 irqbalance daemon will have to be taught to recognize "skge@" as an Ethernet interrupt. This will be a one-liner addition in classify.c. I will send a patch to irqbalance if this change is accepted.

89e95a6 Ori Finkelman 01 October 2009, 06:41:59 UTC IPv4 TCP fails to send window scale option when window scale is zero Acknowledge TCP window scale support by inserting the proper option in SYN/ACK and SYN headers even if our window scale is zero. This fixes the following observed behavior: 1. Client sends a SYN with TCP window scaling option and non zero window scale value to a Linux box. 2. Linux box notes large receive window from client. 3. Linux decides on a zero value of window scale for its part. 4. Due to compare against requested window scale size option, Linux does not to send windows scale TCP option header on SYN/ACK at all. With the following result: Client box thinks TCP window scaling is not supported, since SYN/ACK had no TCP window scale option, while Linux thinks that TCP window scaling is supported (and scale might be non zero), since SYN had TCP window scale option and we have a mismatched idea between the client and server regarding window sizes. Probably it also fixes up the following bug (not observed in practice): 1. Linux box opens TCP connection to some server. 2. Linux decides on zero value of window scale. 3. Due to compare against computed window scale size option, Linux does not to set windows scale TCP option header on SYN. With the expected result that the server OS does not use window scale option due to not receiving such an option in the SYN headers, leading to suboptimal performance.

ce501ca Jiri Pirko 18 September 2009, 02:13:22 UTC bonding: set primary param via sysfs Primary module parameter passed to bonding is pernament. That means if you release the primary slave and enslave it again, it becomes the primary slave again. But if you set primary slave via sysfs, the primary slave is only set once and it's not remembered in bond->params structure. Therefore the setting is lost after releasing the primary slave.

7bfc4ab Anton Vorontsov 01 October 2009, 03:11:11 UTC 3c59x: Rework suspend and resume As noticed by Alan Stern, there is still one issue with the driver: we disable PCI IRQ on suspend, but other devices on the same IRQ line might still need the IRQ enabled to suspend properly. Nowadays, PCI core handles all power management work by itself, with one condition though: if we use dev_pm_ops. So, rework the driver to only quiesce 3c59x internal logic on suspend, while PCI core will manage PCI device power state with IRQs disabled. Suggested-by: Rafael J.

Effect is that tcpdump on real dev can show strange timings, since it gets rx timestamps too late (ie at skb dequeueing time, not at skb queueing time) 14:47:26.986871 IP 192.168.20.110 > 192.168.20.141: icmp 64: echo request seq 1 14:47:26.986786 IP 192.168.20.141 > 192.168.20.110: icmp 64: echo reply seq 1 14:47:27.986888 IP 192.168.20.110 > 192.168.20.141: icmp 64: echo request seq 2 14:47:27.986781 IP 192.168.20.141 > 192.168.20.110: icmp 64: echo reply seq 2 14:47:28.986896 IP 192.168.20.110 > 192.168.20.141: icmp 64: echo request seq 3 14:47:28.986780 IP 192.168.20.141 > 192.168.20.110: icmp 64: echo reply seq 3 Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

This is because the for-loop uses u32 phy_data variable more like a 4-byte field. But in each run only a single byte is calculated.

1f08e84 Igor Perminov 21 September 2009, 20:25:44 UTC mac80211: Fix [re]association power saving issue on AP side Consider the following step-by step: 1. A STA authenticates and associates with the AP and exchanges traffic. 2. The STA reports to the AP that it is going to PS state. 3. Some time later the STA device goes to the stand-by mode (not only its wi-fi card, but the device itself) and drops the association state without sending a disassociation frame. 4. The STA device wakes up and begins authentication with an Auth frame as it hasn't been authenticated/associated previously. At the step 4 the AP "remembers" the STA and considers it is still in the PS state, so the AP buffers frames, which it has to send to the STA. But the STA isn't actually in the PS state and so it neither checks TIM bits nor reports to the AP that it isn't power saving. Because of that authentication/[re]association fails. To fix authentication/[re]association stage of this issue, Auth, Assoc Resp and Reassoc Resp frames are transmitted disregarding of STA's power saving state. N.B. This patch doesn't fix further data frame exchange after authentication/[re]association. A patch in hostapd is required to fix that.

The format of this information is different between 3945 and 4965 and later devices, yet currently the 3945 uses the 4965 and later format. Fix this by adding a new library call that is initialized to the correct formatting routine based on device. This moves the iwlagn event and error log handling back to iwl-agn.c to make it part of iwlagn module. Also remove the 3945 sysfs file that triggers dump of event log - there is already a debugfs file that can do it for all drivers.

2fac971 Reinette Chatre 25 September 2009, 21:24:21 UTC iwlwifi: fix debugfs buffer handling We keep track of where to write into a buffer by keeping a count of how much has been written so far. When writing to the buffer we thus take the buffer pointer and adding the count of what has been written so far. Keeping track of what has been written so far is done by incrementing this number every time something is written to the buffer with how much has been written at that time. Currently this number is incremented incorrectly when using the "hex_dump_to_buffer" call to add data to the buffer. Fix this by only adding what has been added to the buffer in that call instead of what has been added since beginning of buffer.

Though, there are few other issues with suspend/resume in this driver. The intention of calling free_irq() in suspend() was to avoid any possible spurious interrupts (see commit 5b039e681b8c5f30aac9cc04385 "3c59x PM fixes"). But, - On resume, the driver was requesting IRQ just after pci_set_master(), but before vortex_up() (which actually resets 3c59x chips). - Issuing free_irq() on a shared IRQ doesn't guarantee that a buggy HW won't trigger spurious interrupts in another driver that requested the same interrupt. So, if we want to protect from unexpected interrupts, then on suspend we should issue disable_irq(), not free_irq(). Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: David S.
