2008-03-28[netdrvr] tulip_read_eeprom fixes for BUG 4420Grant Grundler
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.

ESP does not account for the IV size when calling pskb_may_pull() to ensure everything it accesses directly is within the linear part of a potential fragment. This results in a BUG() being triggered when the both the IPv4 and IPv6 ESP stack is fed with an skb where the first fragment ends between the end of the esp header and the end of the IV.

2008-03-27rt2x00: Ignore set_state(STATE_SLEEP) failureIvo van Doorn
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>

In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Tomas Winkler <tomas.winkler@intel.com> Cc: Guy Cohen <guy.cohen@intel.com> Cc: Reinette Chatre <reinette.chatre@intel.com> Cc: Zhu Yi <yi.zhu@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: John W.

2008-03-26[IPSEC]: Fix BEET outputHerbert Xu
The IPv6 BEET output function is incorrectly including the inner header in the payload to be protected. This causes a crash as the packet doesn't actually have that many bytes for a second header. The IPv4 BEET output on the other hand is broken when it comes to handling an inner IPv6 header since it always assumes an inner IPv4 header. This patch fixes both by making sure that neither BEET output function touches the inner header at all. All access is now done through the protocol-independent cb structure. Two new attributes are added to make this work, the IP header length and the IPv4 option length. They're filled in by the inner mode's output function.

2008-03-25cxgb3: Fix lockdep problems with sge.reg_lockRoland Dreier
Using iWARP with a Chelsio T3 NIC generates the following lockdep warning: ================================= [ INFO: inconsistent lock state ] 2.6.25-rc6 #50 --------------------------------- inconsistent {softirq-on-W} -> {in-softirq-W} usage. swapper/0 [HC0[0]:SC1[1]:HE0:SE0] takes: (&adap->sge.reg_lock){-+..}, at: [<ffffffff880e5ee2>] cxgb_offload_ctl+0x3af/0x507 [cxgb3] The problem is that reg_lock is used with plain spin_lock() in drivers/net/cxgb3/sge.c but is used with spin_lock_irqsave() in drivers/net/cxgb3/cxgb3_offload.c. 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.
