* net: use software GSO for SG+CSUM capable netdevicesLennert Buytenhek2008-08-031-0/+4
| | | | | | | | | | | | | | | | | If a netdevice does not support hardware GSO, allowing the stack to use GSO anyway and then splitting the GSO skb into MSS-sized pieces as it is handed to the netdevice for transmitting is likely still a win as far as throughput and/or CPU usage are concerned, since it reduces the number of trips through the output path. This patch enables the use of GSO on any netdevice that supports SG. If a GSO skb is then sent to a netdevice that supports SG but does not support hardware GSO, net/core/dev.c:dev_hard_start_xmit() will take care of doing the necessary GSO segmentation in software.

* net: fix missing pneigh entries in the neighbor seq_file codeChris Larson2008-08-031-5/+6
| | | | | | | | | | | | | | | | When pneigh entries exist, but the user's read buffer isn't sufficient to hold them all, one of the pneigh entries will be missing from the results. In neigh_get_idx_any, the number of elements which neigh_get_idx encountered is not correctly subtracted from the position number before the call to pneigh_get_idx. neigh_get_idx reduces the position by 1 for each call to neigh_get_next, but it does not reduce it by one for the first element (neigh_get_first). The patch alters the neigh_get_idx and pneigh_get_idx functions to subtract one from pos, for the first element, when pos is non-zero.

| * rtl8187: Fix lockups due to concurrent access to config routineLarry Finger2008-08-012-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some users of the RTL8187B have experienced difficulties since commit 49292d56352a6ab90d04c3448dd8b6106dfef2d6 that introduced the power management wext hooks. This difficulty has not made much sense until it was realized that it was possible for mac80211 to make a call to the config routine while that routine was already being executed. On this device, it is necessary to loopback the TX when changing channels. Unless this is properly restored, the device will lockup. A mutex now protects the device state, and the private data in several places. The problem was found by Herton Ronaldo Krzesinski <herton@mandriva.com.br>, who also suggested this type of fix.

| * | | KVM: Allow reading aliases with mmu_lockAndrea Arcangeli2008-07-291-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows the mmu notifier code to run unalias_gfn with only the mmu_lock held. Only alias writes need the mmu_lock held. Readers will either take the slots_lock in read mode or the mmu_lock. Signed-off-by: Andrea Arcangeli <andrea@qumranet.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
