2008-02-03PHYLIB: Locking fixes for PHY I/O potentially sleepingNate Case
PHY read/write functions can potentially sleep (e.g., a PHY accessed via I2C). The following changes were made to account for this: * Change spin locks to mutex locks * Add a BUG_ON() to phy_read() phy_write() to warn against calling them from an interrupt context. * Use work queue for PHY state machine handling since it can potentially sleep * Change phydev lock from spinlock to mutex Signed-off-by: Nate Case <ncase@xes-inc.com> Acked-by: Andy Fleming <afleming@freescale.com> Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: David S.

2008-02-03forcedeth: checksum fixAyaz Abdulla
The driver should inform the stack when checksum has been performed by the HW when both IP and TCP (or UDP) checksum flags are indicated by HW. Previously, it would also inform the stack when only IP checksum flag was indicated by HW. This can cause data corruption when IP fragments are used. The IP Identification field can wrap around and cause data from new fragments to fill into older fragment slots with same IP Id. The stack would then not perform TCP/UDP checksum (after re-assembly of all fragments) since driver falsely stated it was already calculated.

2008-02-03cxgb3: Remove incorrect __devinit annotationsRoland Dreier
When PCI error recovery was added to cxgb3, a function t3_io_slot_reset() was added. This function can call back into t3_prep_adapter() at any time, so t3_prep_adapter() can no longer be marked __devinit. This patch removes the __devinit annotation from t3_prep_adapter() and all the functions that it calls, which fixes WARNING: drivers/net/cxgb3/built-in.o(.text+0x2427): Section mismatch in reference from the function t3_io_slot_reset() to the function .devinit.text:t3_prep_adapter() Signed-off-by: Roland Dreier <rolandd@cisco.com> Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: David S.

2008-02-03bonding: do not acquire rtnl in ARP monitorJay Vosburgh
The ARP monitor functions currently acquire RTNL when performing failover operations, but do so incorrectly (out of order). This causes various warnings from might_sleep. The ARP monitor isn't supported for any of the bonding modes that actually require RTNL, so it is safe to not hold RTNL when failing over in the ARP monitor.

2008-02-03bonding: fix race that causes invalid statisticsAndy Gospodarek
I've seen reports of invalid stats in /proc/net/dev for bonding interfaces, and found it's a pretty easy problem to reproduce. Since the current code zeros the bonding stats when a read is requested and a pointer to that data is returned to the caller we cannot guarantee that the caller has completely accessed the data before a successive call to request the stats zeroes the stats again. This patch creates a new stack variable to keep track of the updated stats and copies the data from that variable into the bonding stats structure. This ensures that the value for any of the bonding stats should not incorrectly return zero for any of the bonding statistics. This does use more stack space and require an extra memcpy, but it seems like a fair trade-off for consistently correct bonding statistics.

2008-02-03bonding: fix set_multicast_list lockingJay Vosburgh
This patch eliminates a problem (reported by lockdep) in the bond_set_multicast_list function. It first reduces the locking on bond->lock to a simple read_lock, and second, adds netif_tx locking around the bonding mc_list manipulations that occur outside of the set_multicast_list function. The original problem was related to IPv6 addrconf activity. Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: David S.

I fixed that and coudn't refrain from removing the most egregious warts. - mipsnet.h folded into mipsnet.c, as it doesn't provide any useful external interface. - Free SKB after transmission. - Call free_irq in mipsnet_close, to balance the request_irq in mipsnet_open. - Removed duplicate read of rxDataCount. - Some identifiers are now less verbose. - Removed dead and/or unnecessarily complex code. - Code formatting fixes. Tested on Qemu's mipssim emulation, with this patch it can boot a Debian NFSroot.

Doing that without ntohl() is an interesting idea and it might even work occasionally; unfortunately, it's quite broken.

2008-02-03macb: Fix section mismatch and shrink runtime footprintHaavard Skinnemoen
macb devices are only found integrated on SoCs, so they can't be hotplugged. Thus, the probe() and exit() functions can be __init and __exit, respectively. By using platform_driver_probe() instead of platform_driver_register(), there won't be any references to the discarded probe() function after the driver has loaded. This also fixes a section mismatch due to macb_probe(), defined as __devinit, calling macb_get_hwaddr, defined as __init.
