The patch provides workaround for BUG in FW 7.2.16, which in GRO mode may miscalculate buffer and place on SGE one frag less than it could. It may happen only for some MTUs, we mark these MTUs with gro_check flag during device initialization or MTU change. Next FW should include fix for the issue and the patch could be reverted.

2012-02-20use FW 7.2.16Dmitry Kravkov
The patch integrates FW 7.2.16 HSI and implements driver part of GRO flow. FW 7.2.16 adds the ability to aggregate packets for GRO (and not just LRO) and also fixes some bugs. 1. Added new aggregation mode: GRO. In this mode packets are aggregated such that the original packets can be reconstructed by the OS. 2. 57712 HW bug workaround - initialized all CAM TM registers to 0x32. 3. Adding the FCoE statistics structures to the BNX2X HSI. 4. Wrong configuration of TX HW input buffer size may cause theoretical performance effect. Performed configuration fix. 5. FCOE - Arrival of packets beyond task IO size can lead to crash. Fix firmware data-in flow. 6. iSCSI - In rare cases of on-chip termination the graceful termination timer hangs, and the termination doesn't complete. Firmware fix to MSL timer tolerance. 7. iSCSI - Chip hangs when target sends FIN out-of-order or with isles open at the initiator side. Firmware implementation corrected to drop FIN received out-of-order or with isles still open. 8. iSCSI - Chip hangs when in case of retransmission not aligned to 4-bytes from the beginning of iSCSI PDU. Firmware implementation corrected to support arbitrary aligned retransmissions. 9. iSCSI - Arrival of target-initiated NOP-IN during intense ISCSI traffic might lead to crash.

2012-02-18i387: re-introduce FPU state preloading at context switch timeLinus Torvalds
After all the FPU state cleanups and finally finding the problem that caused all our FPU save/restore problems, this re-introduces the preloading of FPU state that was removed in commit b3b0870ef3ff ("i387: do not preload FPU state at task switch time"). However, instead of simply reverting the removal, this reimplements preloading with several fixes, most notably - properly abstracted as a true FPU state switch, rather than as open-coded save and restore with various hacks. In particular, implementing it as a proper FPU state switch allows us to optimize the CR0.TS flag accesses: there is no reason to set the TS bit only to then almost immediately clear it again. CR0 accesses are quite slow and expensive, don't flip the bit back and forth for no good reason. - Make sure that the same model works for both x86-32 and x86-64, so that there are no gratuitous differences between the two due to the way they save and restore segment state differently due to architectural differences that really don't matter to the FPU state. - Avoid exposing the "preload" state to the context switch routines, and in particular allow the concept of lazy state restore: if nothing else has used the FPU in the meantime, and the process is still on the same CPU, we can avoid restoring state from memory entirely, just re-expose the state that is still in the FPU unit. That optimized lazy restore isn't actually implemented here, but the infrastructure is set up for it. Of course, older CPU's that use 'fnsave' to save the state cannot take advantage of this, since the state saving also trashes the state. In other words, there is now an actual _design_ to the FPU state saving, rather than just random historical baggage. Hopefully it's easier to follow as a result.

2012-02-18i387: move TS_USEDFPU flag from thread_info to task_structLinus Torvalds
This moves the bit that indicates whether a thread has ownership of the FPU from the TS_USEDFPU bit in thread_info->status to a word of its own (called 'has_fpu') in task_struct->thread.has_fpu. This fixes two independent bugs at the same time: - changing 'thread_info->status' from the scheduler causes nasty problems for the other users of that variable, since it is defined to be thread-synchronous (that's what the "TS_" part of the naming was supposed to indicate). So perfectly valid code could (and did) do ti->status |= TS_RESTORE_SIGMASK; and the compiler was free to do that as separate load, or and store instructions. Which can cause problems with preemption, since a task switch could happen in between, and change the TS_USEDFPU bit. The change to TS_USEDFPU would be overwritten by the final store. In practice, this seldom happened, though, because the 'status' field was seldom used more than once, so gcc would generally tend to generate code that used a read-modify-write instruction and thus happened to avoid this problem - RMW instructions are naturally low fat and preemption-safe. - On x86-32, the current_thread_info() pointer would, during interrupts and softirqs, point to a *copy* of the real thread_info, because x86-32 uses %esp to calculate the thread_info address, and thus the separate irq (and softirq) stacks would cause these kinds of odd thread_info copy aliases. This is normally not a problem, since interrupts aren't supposed to look at thread information anyway (what thread is running at interrupt time really isn't very well-defined), but it confused the heck out of irq_fpu_usable() and the code that tried to squirrel away the FPU state. (It also caused untold confusion for us poor kernel developers). It also turns out that using 'task_struct' is actually much more natural for most of the call sites that care about the FPU state, since they tend to work with the task struct for other reasons anyway (ie scheduling). And the FPU data that we are going to save/restore is found there too. Thanks to Arjan Van De Ven <arjan@linux.intel.com> for pointing us to the %esp issue.

2012-02-16i387: move AMD K7/K8 fpu fxsave/fxrstor workaround from save to restoreLinus Torvalds
The AMD K7/K8 CPUs don't save/restore FDP/FIP/FOP unless an exception is pending. In order to not leak FIP state from one process to another, we need to do a floating point load after the fxsave of the old process, and before the fxrstor of the new FPU state. That resets the state to the (uninteresting) kernel load, rather than some potentially sensitive user information. We used to do this directly after the FPU state save, but that is actually very inconvenient, since it (a) corrupts what is potentially perfectly good FPU state that we might want to lazy avoid restoring later and (b) on x86-64 it resulted in a very annoying ordering constraint, where "__unlazy_fpu()" in the task switch needs to be delayed until after the DS segment has been reloaded just to get the new DS value. Coupling it to the fxrstor instead of the fxsave automatically avoids both of these issues, and also ensures that we only do it when actually necessary (the FP state after a save may never actually get used).

Yes, taking the trap to re-load the FPU/MMX state is expensive, but so is spending several days looking for a bug in the state save/restore code. And the preload code has some rather subtle interactions with both paravirtualization support and segment state restore, so it's not nearly as simple as it should be. Also, now that we no longer necessarily depend on a single bit (ie TS_USEDFPU) for keeping track of the state of the FPU, we migth be able to do better. If we are really switching between two processes that keep touching the FP state, save/restore is inevitable, but in the case of having one process that does most of the FPU usage, we may actually be able to do much better than the preloading. In particular, we may be able to keep track of which CPU the process ran on last, and also per CPU keep track of which process' FP state that CPU has. For modern CPU's that don't destroy the FPU contents on save time, that would allow us to do a lazy restore by just re-enabling the existing FPU state - with no restore cost at all!

2012-02-16net: sh_eth: add support for VLAN tag filteringYoshihiro Shimoda
Some controllers have TSU. It can register one VLAN tag, and it can filter other VLAN tag by hardware. If vlan_rx_add_vid() is called twice or more, the driver will disable the filtering.

2012-02-16net: sh_eth: modify a condition of ioremap for TSUYoshihiro Shimoda
If the controller has TSU, the each channel needs TSU registers. This patch also fixes the iounmap condition in the sh_eth_drv_remove(). Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-02-16net: sh_eth: change the condition of initializationYoshihiro Shimoda
The SH7757 has 2 Fast Ethernet and 2 Gigabit Ethernet, and the first Gigabit channel needs the initialization. So, this patch adds the parameter of "needs_init", and if the sh_eth_plat_data is set it to 1, the driver will initialize the channel.

2012-02-16eCryptfs: Copy up lower inode attrs after setting lower xattrTyler Hicks
After passing through a ->setxattr() call, eCryptfs needs to copy the inode attributes from the lower inode to the eCryptfs inode, as they may have changed in the lower filesystem's ->setxattr() path. One example is if an extended attribute containing a POSIX Access Control List is being set. The new ACL may cause the lower filesystem to modify the mode of the lower inode and the eCryptfs inode would need to be updated to reflect the new mode. https://launchpad.net/bugs/926292 Signed-off-by: Tyler Hicks <tyhicks@canonical.com> Reported-by: Sebastien Bacher <seb128@ubuntu.com> Cc: John Johansen <john.johansen@canonical.com> Cc: <stable@vger.kernel.org>
