While a privileged program can open a raw socket, attach some restrictive filter and drop its privileges (or send the socket to an unprivileged program through some Unix socket), the filter can still be removed or modified by the unprivileged program. This commit adds a socket option to lock the filter (SO_LOCK_FILTER) preventing any modification of a socket filter program. This is similar to OpenBSD BIOCLOCK ioctl on bpf sockets, except even root is not allowed change/drop the filter. The state of the lock can be read with getsockopt(). No error is triggered if the state is not changed. -EPERM is returned when a user tries to remove the lock or to change/remove the filter while the lock is active. The check is done directly in sk_attach_filter() and sk_detach_filter() and does not affect only setsockopt() syscall. Signed-off-by:

Rather than generating a different RSS key on each boot, just use a predetermined value that will map same flow to same value on every device for more predictable testing. This is already done on most hardware drivers. Initial key value just some arbitrary bits extracted once from /dev/random. Signed-off-by:

This messages that occur during boot time from this device when netdev_err is called before calling register_netdevice(). Switch to using dev_XXX macros which correlate message with PCI info which is available. Rather than fixing the features message, just remove it since the information is redundant and available through ethtool. Signed-off-by:

When there is heavy traffic and the cable is pulled, the driver must reset the adapter to flush the Tx queue in hardware. This causes the reset path to be scheduled and logs the message "Reset adapter" which could be mis- interpreted as an error by the user. Change how the reset path is invoked for this scenario by using the same method done in an existing work-around for 80003es2lan (i.e. set a flag and if the flag is set in the reset code do not log the "Reset adapter" message since the reset is expected). Re-name the FLAG_RX_RESTART_NOW to FLAG_RESTART_NOW since it is used for resets in both the Rx and Tx specific code. Signed-off-by:

Energy Efficient Ethernet on 82579 and I217 should only be enabled if not disabled by the user, if the link is full duplex and the link partner has similar EEE capabilities (stored in different EMI registers on the two different parts). After enabling EEE, read the IEEE MMD register 3.1 (which is also stored in different EMI registers on the two different parts) to clear the count of received Tx/Rx LPI indications. Also, rename I217_EEE_100_SUPPORTED to I82579_EEE_100_SUPPORTED to indicate the bit is valid starting with I82579 (released before I217). Signed-off-by:

When data blocks are written to the EEPROM, the HW/SW/FW semaphore must be held for the duration. With large data blocks on 80003es2lan, 82571 and 82572, this can take too long and cause the firmware to take ownership of the semaphore and consequently ownership of writes to the EEPROM. Instead, acquire and release the semaphore for each page of the block written. Signed-off-by:

Since submit 621b4d66 the bnx2x driver support FW GRO. However, when using the device with GRO enabled in bridging scenarios throughput is very low, as the bridge expects all incoming packets to be passed with CHECKSUM_PARTIAL - a demand which is satisfied by the SW GRO implementation, but was missed in the bnx2x driver implementation (which returned CHECKSUM_UNNECESSARY). Now, given that the traffic is supported by FW GRO (TCP/IP), the bnx2x driver calculates the pseudo checksum by itself, passing skbs with CHECKSUM_PARTIAL and giving a much better throughput when receiving GRO traffic.
