From 36e1e84768b1123eb632aff153104855c71684cc Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Tue, 27 Jun 2006 07:38:33 -0400 Subject: [PATCH 01/39] [netdrvr] epic100: minor cleanups - Remove in-source changelog, it's in the global kernel history. - convert silly and useless version to useful one - replace invariant pci_id_tbl[]::io_size uses with EPIC_TOTAL_SIZE - remove now-unused io_size member from pci_id_tbl[] - current kernel style prefers dev_printk() for the rare ethernet driver messages that cannot print an 'eth%d' prefix.

These days, the kernel's changelog is far superior and much more accurate, so the in-driver changelogs are removed. Another relic of the Becker/kernel split was version numbering, using "foo-LKx.y.z" notation, resulting in weird version numbers like "1.17b-LK1.1.9". These drivers are for older hardware, and see few changes these days, so the version numbers were all bumped to something more simple. Finally, in xircom_tulip_cb specifically, an additional cleanup removes the always-enabled CARDBUS cpp macro.

As denoted by its name, it completes the capabilities IE that is needed in the associate and reassociate requests sent to the AP. For at least one AP, the Linksys WRT54G V5, the capabilities field must set the 'short preamble' bit or the AP refuses to associate. In the commit noted above, there is a call to the new routine from ieee80211softmac_reassoc_req, but not from ieee80211softmac_assoc_req. This patch fixes that oversight. As noted in the subject, v2.6.17 is affected. My bcm43xx card had been unable to associate since I was forced to buy a new AP. I finally was able to get a packet dump and traced the problem to the capabilities info. Although I had heard that a patch was "floating around", I had not seen it before 2.6.17 was released. As this bug does not affect security and I seem to have the only AP affected by it, there should be no problem in leaving it for 2.6.18. Signed-Off-By: Larry Finger Signed-off-by: John W.

These appear due to scheduling multiple authentication attempts on the same network. To prevent this, I added a flag to stop multiple authentication attempts by the association layer. I also added a check to the wx handler to see if we're connecting to a different network than the one already in progress. This scenario was causing multiple requests on the same network because the network BSSID was not being updated despite the fact that the ESSID changed.

Unlike the predecessor (ZD1201), ZD1211 does not have a hardware MAC, so most data operations are coordinated by the device driver. The ZD1211 chip sits alongside an RF transceiver which is also controlled by the driver. Our driver currently supports 2 RF types, we know of one other available in a few marketed products which we will be supporting soon. Our driver also supports the newer revision of ZD1211, called ZD1211B. The initialization and RF operations are slightly different for the new revision, but the main difference is 802.11e support. Our driver does not support the QoS features yet, but we think we know how to use them. This driver is based on ZyDAS's own GPL driver available from www.zydas.com.tw. ZyDAS engineers have been responsive and supportive of our efforts, so thumbs up to them. Additionally, the firmware is redistributable and they have provided device specs. This driver has been written primarily by Ulrich Kunitz and myself. Graham Gower, Greg KH, Remco and Bryan Rittmeyer have also contributed. The developers of ieee80211 and softmac have made our lives so much easier- thanks! We maintain a small info-page: http://zd1211.ath.cx/wiki/DriverRewrite If there is enough time for review, we would like to aim for inclusion in 2.6.18. The driver works nicely as a STA, and can connect to both open and encrypted networks (we are using software-based encryption for now). We will work towards supporting more advanced features in the future (ad-hoc, master mode, 802.11a, ...). Signed-off-by: Daniel Drake Signed-off-by: John W.

Nathan reported the following lockdep warning: [ 197.343948] BUG: warning at kernel/lockdep.c:1856/trace_hardirqs_on() [ 197.345928] [] show_trace_log_lvl+0x5b/0x105 [ 197.346359] [] show_trace+0x1b/0x20 [ 197.346759] [] dump_stack+0x1f/0x24 [ 197.347159] [] trace_hardirqs_on+0xfb/0x185 [ 197.348873] [] _spin_unlock_irq+0x24/0x2d [ 197.350620] [] do_tx_done+0x171/0x179 [ns83820] [ 197.350895] [] ns83820_irq+0x149/0x20b [ns83820] [ 197.351166] [] handle_IRQ_event+0x1d/0x52 [ 197.353216] [] handle_level_irq+0x97/0xe1 [ 197.355157] [] do_IRQ+0x8b/0xac [ 197.355612] [] common_interrupt+0x25/0x2c this is caused because the ns83820 driver re-enables irq flags in hardirq context. While legal in theory, in practice it should only be done if the hardware is really old and has some very high overhead in its ISR. (such as PIO IDE) For modern hardware, running ISRs with irqs enabled is discouraged, because 1) new hardware is fast enough to not cause latency problems 2) allowing the nesting of hardware interrupts only 'spreads out' the handling of the current ISR, causing extra cachemisses that would otherwise not happen. Furthermore, on architectures where ISRs share the kernel stacks, enabling interrupts in ISRs introduces a much higher kernel-stack-nesting and thus kernel-stack-overflow risk. 3) not managing irq-flags via the _irqsave / _irqrestore variants is dangerous: it's easy to forget whether one function nests inside another, and irq flags might be mismanaged. In the few cases where re-enabling interrupts in an ISR is considered useful (and unavoidable), it has to be taught to the lock validator explicitly (because the lock validator needs the "no ISR ever enables hardirqs" artificial simplification to keep the IRQ/softirq locking dependencies manageable). This teaching is done via the explicit use local_irq_enable_in_hardirq(). On a stock kernel this maps to local_irq_enable(). If the lock validator is enabled then this does not enable interrupts. Now, the analysis of drivers/net/ns83820.c's irq flags use: the irq-enabling in irq context seems intentional, but i dont think it's justified. Furthermore, the driver suffers from problem #3 above too, in ns83820_tx_timeout() it disables irqs via local_irq_save(), but then it calls do_tx_done() which does a spin_unlock_irq(), re-enabling for a function that does not expect it! While currently this bug seems harmless (only some debug printout seems to be affected by it), it's nevertheless something to be fixed. So this patch makes the ns83820 ISR irq-flags-safe, and cleans up do_tx_done() use and locking to avoid the ns83820_tx_timeout() bug. From: Arjan van de Ven ns83820_mib_isr takes the misc_lock in IRQ context. All other places that do this in the ISR already use _irqsave versions, make this consistent at least. At some point in the future someone should audit the driver to see if all _irqsave's in the ISR can go away, this is generally an iffy/fragile proposition though; for now get it safe, simple and consistent. From: Arjan van de Ven ok this is a real driver deadlock: The ns83820 driver enabled interrupts (by unlocking the misc_lock with _irq) while still holding the rx_info.lock, which is required to be irq safe since it's used in the ISR like this: writel(1, dev->base + IER); spin_unlock_irq(&dev->misc_lock); kick_rx(ndev); spin_unlock_irq(&dev->rx_info.lock); This is can cause a deadlock if an irq was pending at the first spin_unlock_irq already, or if one would hit during kick_rx(). Simply remove the first _irq solves this Signed-off-by: Ingo Molnar Cc: Benjamin LaHaise Cc: Jeff Garzik Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Jeff Garzik --- drivers/net/ns83820.c | 31 +++++++++++++++++-------------- 1 file changed, 17 insertions(+), 14 deletions(-) diff --git a/drivers/net/ns83820.c b/drivers/net/ns83820.c index d0ed8646902f..0e76859c90a2 100644 --- a/drivers/net/ns83820.c +++ b/drivers/net/ns83820.c @@ -803,7 +803,7 @@ static int ns83820_setup_rx(struct net_device *ndev) writel(dev->IMR_cache, dev->base + IMR); writel(1, dev->base + IER); - spin_unlock_irq(&dev->misc_lock); + spin_unlock(&dev->misc_lock); kick_rx(ndev); @@ -1012,8 +1012,6 @@ static void do_tx_done(struct net_device *ndev) struct ns83820 *dev = PRIV(ndev); u32 cmdsts, tx_done_idx, *desc; - spin_lock_irq(&dev->tx_lock); - dprintk("do_tx_done(%p)\n", ndev); tx_done_idx = dev->tx_done_idx; desc = dev->tx_descs + (tx_done_idx * DESC_SIZE); @@ -1069,7 +1067,6 @@ static void do_tx_done(struct net_device *ndev) netif_start_queue(ndev); netif_wake_queue(ndev); } - spin_unlock_irq(&dev->tx_lock); } static void ns83820_cleanup_tx(struct ns83820 *dev) @@ -1281,11 +1278,13 @@ static struct ethtool_ops ops = { .get_link = ns83820_get_link }; +/* this function is called in irq context from the ISR */ static void ns83820_mib_isr(struct ns83820 *dev) { - spin_lock(&dev->misc_lock); + unsigned long flags; + spin_lock_irqsave(&dev->misc_lock, flags); ns83820_update_stats(dev); - spin_unlock(&dev->misc_lock); + spin_unlock_irqrestore(&dev->misc_lock, flags); } static void ns83820_do_isr(struct net_device *ndev, u32 isr); @@ -1307,6 +1306,8 @@ static irqreturn_t ns83820_irq(int foo, void *data, struct pt_regs *regs) static void ns83820_do_isr(struct net_device *ndev, u32 isr) { struct ns83820 *dev = PRIV(ndev); + unsigned long flags; + #ifdef DEBUG if (isr & ~(ISR_PHY | ISR_RXDESC | ISR_RXEARLY | ISR_RXOK | ISR_RXERR | ISR_TXIDLE | ISR_TXOK | ISR_TXDESC)) Dprintk("odd isr?
