From d07bd86d82622247dba8cc29974d3860f857ea33 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Mon, 2 May 2011 16:36:48 -0400 Subject: arch/tile: clarify flush_buffer()/finv_buffer() function names They are only applicable for locally-homecached memory ranges, so change their names to {flush,finv}_buffer_local(). Change inv_buffer() to just do an mf instead of any kind of fancier barrier, since you're obviously not going to be waiting for anything once the local homecache is invalidated. Fix tilepro.c network driver not to bother calling finv_buffer when stopping the EPP, but just mf after memset to ensure that it will not see any packet data after we finish stopping; use finv_buffer_remote() when doing exit-time cleanup. This also fixes a (not very interesting) generic Linux build failure where drivers/scsi/st.c declares its own flush_buffer().

Additionally, we often copy data around quite pointlessly since we could instead map the existing scan buffer for example and use it directly. This patch makes that possible. The first change is that multiple buffers may be given to each command (this change was prepared earlier so callsites don't need to change). Each of those can be mapped attached to a TB in the TFD, and the command header can use a TB (the first one) in the TFD as well. Doing this allows getting rid of huge commands in favour of mapping existing buffers. The beacon transmission is also optimised to not copy the SKB at all but use multiple TBs.

However, sme implementation does not use the frequency when fetching the BSS entry. Fix this by adding channel information to cfg80211_roamed() and include it in cfg80211_get_bss() calls. Please note that drivers using cfg80211_roamed() need to be modified to fully implement this fix. This commit includes only minimal changes to avoid compilation issues; it maintains the old (broken) behavior for most drivers. ath6kl was the only one that I could test, so I updated it to provide the operating frequency in the roamed event.

This patch adds a driver for the hardware time stamping unit found on the IXP465. The basic clock operations and an external trigger are implemented.

-- cgit v1.1 From cb646e2b02b27a33a1d1eabd016749606254071c Mon Sep 17 00:00:00 2001 From: Richard Cochran Date: Fri, 22 Apr 2011 12:04:55 +0200 Subject: ptp: Added a clock driver for the National Semiconductor PHYTER. This patch adds support for the PTP clock found on the DP83640. The basic clock operations and one external time stamp have been implemented.

But it should register if the logical port is in promiscuous mode, but the physical port is not. Ehea physical promiscuous mode is defined by ehea_port->promisc, while logical port is defined by IFF_PROMISC. So currently, if the user set the interface in promiscuous mode, IGMP will not be registred in PHYP, and PHYP will never pass the multicast packet to the logical port, which is bad So, this patch just fixes it, assuring that we register in phyp if the physical port is not on promiscuous mode.

This patch now passes the filter argument to show_free_areas() so those nodes are now avoided. This patch also removes the show_free_areas() wrapper around __show_free_areas() and converts existing callers to pass an empty filter. ia64 emits additional information for each node, so skip_free_areas_zone() must be made global to filter disallowed nodes and it is converted to use a nid argument rather than a zone for this use case.

The bonding driver initializes some data structures only after its ndo_open routine is called. Among them is the initalization of the alb tx and rx hash locks. So if we add or remove a slave without first opening the bond master device, we run the risk of trying to lock/unlock a spinlock that has garbage for data in it, which results in our above softlock. Note that sometimes this works, because in many cases an unlocked spinlock has the raw_lock parameter initialized to zero (meaning that the kzalloc of the net_device private data is equivalent to calling spin_lock_init), but thats not true in all cases, and we aren't guaranteed that condition, so we need to pass the relevant spinlocks through the spin_lock_init function. Fix it by moving the spin_lock_init calls for the tx and rx hashtable locks to the ndo_init path, so they are ready for use by the bond_store_slaves path. Change notes: v2) Based on conversation with Jay and Nicolas it seems that the ability to enslave devices while the bond master is down should be safe to do. As such this is an outlier bug, and so instead we'll just initalize the errant spinlocks in the init path rather than the open path, solving the problem. We'll also remove the warnings about the bond being down during enslave operations, since it should be safe v3) Fix spelling error Signed-off-by: Neil Horman Reported-by: jtluka@redhat.com CC: Jay Vosburgh CC: Andy Gospodarek CC: nicolas.2p.debian@gmail.com CC: "David S.

So for handling event only 4 more bytes needs to be pulled. This is achieved by changing event header length to 4. Almost all the events, except BA stream related and AMSDU aggregation control events, do not have the payload in their event skb. Such events handling depends only on the event ID. This event ID is the first four bytes of the event skb, which is copied to a separate variable before pulling the skb header. Hence event handling worked only for those events that didn't have payload in event skb. This patch fixes the broken event path of the events with payload in their event skb without harming existing working event path for the events without payload.

Under heavy load, this causes fragmentation of memory. The present code releases the current buffer before checking to see if a new one is availble. Recovery from allocation failures is not possible, which results in kernel panics. The fix is to reorder the code to check that a new buffer can be allocated before the old one is released. If not possible, the received frame is dropped and the old one is reused. Without this change, it is impossible to transfer a 2 GB file without a kernel panic.

Problem here is that usb_bulk_msg() on interrupt endpoint selfcorrects the call and changes requested pipe to interrupt type (see usb_bulk_msg). However with usb_interrupt_msg() on bulk endpoint does not correct the pipe type to bulk, but instead URB is submitted with interrupt type pipe. So pre-2.6.39 used usb_bulk_msg() and therefore worked with both endpoint types, however in 2.6.39 usb_interrupt_msg() with bulk endpoint causes ohci_hcd to fail submitted URB instantly with -ENOSPC and preventing zd1211rw from working with OHCI. Fix this by detecting endpoint type and using correct endpoint/pipe types for URB. Also fix asynchronous zd_usb_iowrite16v_async() to use right URB type on 'EP 4 OUT'.

This means that if the chip is asserting interrupt for some reason we can end up with a screaming IRQ that the interrupt handler is unable to deal with. Avoid this by only requesting the interrupt after we've reset the chip so we know what state it's in. This started manifesting itself on one of my boards in the past month or so, I suspect as a result of some core infrastructure changes removing some form of mitigation against bad behaviour here, even when things boot it seems that the new code brings the interface up more quickly.

It was broken in so many ways, and results in random odd pty issues. It re-introduced the buggy schedule_work() in flush_to_ldisc() that can cause endless work-loops (see commit a5660b41af6a: "tty: fix endless work loop when the buffer fills up"). It also used an "unsigned int" return value fo the ->receive_buf() function, but then made multiple functions return a negative error code, and didn't actually check for the error in the caller. And it didn't actually work at all. BenH bisected down odd tty behavior to it: "It looks like the patch is causing some major malfunctions of the X server for me, possibly related to PTYs. For example, cat'ing a large file in a gnome terminal hangs the kernel for -minutes- in a loop of what looks like flush_to_ldisc/workqueue code, (some ftrace data in the quoted bits further down). ... Some more data: It -looks- like what happens is that the flush_to_ldisc work queue entry constantly re-queues itself (because the PTY is full ?) and the workqueue thread will basically loop forver calling it without ever scheduling, thus starving the consumer process that could have emptied the PTY." which is pretty much exactly the problem we fixed in a5660b41af6a. Milton Miller pointed out the 'unsigned int' issue.
