| | * | [netdrvr] tulip_read_eeprom fixes for BUG 4420Grant Grundler2008-03-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If "location" is > "addr_len" bits, the high bits of location would interfere with the READ_CMD sent to the eeprom controller. A patch was submitted to bug: http://bugzilla.kernel.org/show_bug.cgi?id=4420 which simply truncated the "location", read whatever was in "location modulo addr_len", and returned that value. That avoids confusing the eeprom but seems like the wrong solution to me. Correct would be to not read beyond "1 << addr_len" address of the eeprom. I am submitting two changes to implement this: 1) tulip_read_eeprom will return zero (since we can't return -EINVAL) if this is attempted (defensive programming). 2) In tulip_core.c, fix the tulip_read_eeprom caller so they don't iterate past addr_len bits and make sure the entire tp->eeprom[] array is cleared. I konw we don't strictly need both. I would prefer both in the tree since it documents the issue and provides a second "defense" from the bug from creeping back in.

| * | rt2x00: Ignore set_state(STATE_SLEEP) failureIvo van Doorn2008-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some hardware never seem to accept the "goto sleep" command, since the legacy drivers don't have suspend and resume handlers the entire code for it was basically a educated guess (based on the "enable radio" code). This patch will only print a warning when the "goto sleep" command fails, and just continues as usual. Perhaps that means the device will not reach a sleep state and consumes more power then it should, but it is equally possible it simply needs some seconds longer to sleep. Anyway, by making the command non-fatal it will not block the rest of the suspend procedure. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | | plip: replace spin_lock_irq with spin_lock_irqsave in irq contextMikulas Patocka2008-04-01
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | Plip uses spin_lock_irq/spin_unlock_irq in its IRQ handler (called from parport IRQ handler), the latter enables interrupts without parport subsystem IRQ handler expecting it. The bug can be seen if you compile kernel with lock dependency checking and use plip --- it produces a warning. This patch changes it to spin_lock_irqsave/spin_lock_irqrestore, so that it doesn't enable interrupts when already disabled. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This is already captured by having them as __devexit_p in the pci_driver struct - these are supposed to be pointers to __devexit functions, but was not. This is now fixed.

This is technically a false positive, since the uses in sge.c are only in the initialization and cleanup paths and cannot overlap with any use in interrupt context. The best fix is probably just to use spin_lock_irq() with reg_lock in sge.c. Even though it's not strictly required for correctness, it avoids triggering lockdep and the extra overhead of disabling interrupts is not important at all in the initialization and cleanup slow paths.

This fixes it by checking the pointer first. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by Johannes Berg: I started getting this warning with recent kernels: [ 773.908927] ------------[ cut here ]------------ [ 773.908954] Badness at net/core/dev.c:2204 ... If we loop more than once in gem_poll(), we'll use more than the real budget in our gem_rx() calls, thus eventually trigger the caller's assertions in net_rx_action(). Subtract "work_done" from "budget" for the second arg to gem_rx() to fix the bug. Signed-off-by: David S. Miller <davem@davemloft.net>
