2011-05-05mac80211: Fix a warning due to skipping tailroom reservation for IVMohammed Shafi Shajakhan1-2/+4
The devices that require IV generation in software need tailroom reservation for ICVs used in TKIP or WEP encryptions. Currently, decision to skip the tailroom reservation in the tx path was taken only on whether driver wants MMIC to be generated in software or not. Following patch appends IV generation check for such decisions and fixes the following warning.

2011-05-04ixgbe: improve EEPROM read/write operationsEmil Tantilov7-100/+465
Introduce buffered read/writes which greatly improves performance on parts with large EEPROMs. Previously reading/writing a word requires taking/releasing of synchronization semaphores which adds 10ms to each operation. The optimization is to read/write in buffers, but make sure the semaphore is not held for >500ms according to the datasheet. Since we can't read the EEPROM page size ixgbe_detect_eeprom_page_size() is used to discover the EEPROM size when needed and keeps the result in word_page_size for the rest of the run time. Use buffered reads for ethtool -e. Signed-off-by: Emil Tantilov <emil.s.tantilov@intel.com> Tested-by: Evan Swanson <evan.swanson@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2011-05-02net: dont hold rtnl mutex during netlink dump callbacksEric Dumazet8-23/+25
Four years ago, Patrick made a change to hold rtnl mutex during netlink dump callbacks. I believe it was a wrong move. This slows down concurrent dumps, making good old /proc/net/ files faster than rtnetlink in some situations. This occurred to me because one "ip link show dev ..." was _very_ slow on a workload adding/removing network devices in background. All dump callbacks are able to use RCU locking now, so this patch does roughly a revert of commits : 1c2d670f366 : [RTNETLINK]: Hold rtnl_mutex during netlink dump callbacks 6313c1e0992 : [RTNETLINK]: Remove unnecessary locking in dump callbacks This let writers fight for rtnl mutex and readers going full speed. It also takes care of phonet : phonet_route_get() is now called from rcu read section.

2011-05-02ipv4: Make sure flowi4->{saddr,daddr} are always set.David S. Miller1-6/+5
Slow path output route resolution always makes sure that ->{saddr,daddr} are set, and also if we trigger into IPSEC resolution we initialize them as well, because xfrm_lookup() expects them to be fully resolved. But if we hit the fast path and flowi4->flowi4_proto is zero, we won't do this initialization. Therefore, move the IPSEC path initialization to the route cache lookup fast path to make sure these are always set. Signed-off-by: David S. Miller <davem@davemloft.net>

2011-05-02mac80211: consolidate MIC failure report handlingChristian Lamparter2-61/+48
Currently, mac80211 handles MIC failures differently depending on whenever they are detected by the stack's own software crypto or when are handed down from the driver. This patch tries to unify both by moving the special branch out of mac80211 rx hotpath and into into the software crypto part. This has the advantage that we can run a few more sanity checks on the data and verify if the key type was TKIP. This is very handy because several devices generate false postive MIC failure reports.
