* net/gianfar: drop recycled skbs on MTU changeSebastian Andrzej Siewior2010-05-06
| | | | | | | | | | | The size for skbs which is added to the recycled list is using the current descriptor size which is current MTU. gfar_new_skb() is also using this size. So after changing or alteast increasing the MTU all recycled skbs should be dropped.

| * gianfar: Fix TX ring processing on SMP machinesAnton Vorontsov2010-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with commit a3bc1f11e9b867a4f49505 ("gianfar: Revive SKB recycling") gianfar driver sooner or later stops transmitting any packets on SMP machines. start_xmit() prepares new skb for transmitting, generally it does three things: 1. sets up all BDs (marks them ready to send), except the first one. 2. stores skb into tx_queue->tx_skbuff so that clean_tx_ring() would cleanup it later. 3. sets up the first BD, i.e. marks it ready. Here is what clean_tx_ring() does: 1. reads skbs from tx_queue->tx_skbuff 2. checks if the *last* BD is ready. If it's still ready [to send] then it it isn't transmitted, so clean_tx_ring() returns. Otherwise it actually cleanups BDs. All is OK. Now, if there is just one BD, code flow: - start_xmit(): stores skb into tx_skbuff. Note that the first BD (which is also the last one) isn't marked as ready, yet. - clean_tx_ring(): sees that skb is not null, *and* its lstatus says that it is NOT ready (like if BD was sent), so it cleans it up (bad!) - start_xmit(): marks BD as ready [to send], but it's too late. We can fix this simply by reordering lstatus/tx_skbuff writes.

* gianfar: Fix gianfar select_queue bogositySandeep Gopalpet2009-12-26
| | | | | | | | | | | | | | | The gfar_select_queue() function was used to set queue mapping only for forwarding/bridging applications and the condition for locally generated packets was completely ignored. The solution is to remove the gfar_select_queue() function and use skb_record_rx_queue to set queue mapping for forwarding/bridging applications. This will ensure that in case of forwarding/bridging applications txq = rxq will be selected and skb_tx_hash will be used to pick up a txq for locally generated packets.

* gianfar: Revive SKB recyclingAnton Vorontsov2009-11-11
| | | | | | | | | | | | | | | | | | Before calling gfar_clean_tx_ring() the driver grabs an irqsave spinlock, and then tries to recycle skbs. But since skb_recycle_check() returns 0 with IRQs disabled, we'll never recycle any skbs. It appears that gfar_clean_tx_ring() and gfar_start_xmit() are mostly idependent and can work in parallel, except when they modify num_txbdfree. So we can drop the lock from most sections and thus fix the skb recycling.

Fixed up trivial conflicts: - arch/x86/include/asm/socket.h converted to <asm-generic/socket.h> in the x86 tree. The generic header has the same new #define's, so that works out fine. - drivers/net/tun.c fix conflict between 89f56d1e9 ("tun: reuse struct sock fields") that switched over to using 'tun->socket.sk' instead of the redundantly available (and thus removed) 'tun->sk', and 2b980dbd ("lsm: Add hooks to the TUN driver") which added a new 'tun->sk' use. Noted in 'next' by Stephen Rothwell.

| * gianfar: fix BUG under load after introduction of skb recyclingLennert Buytenhek2009-05-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 0fd56bb5be6455d0d42241e65aed057244665e5e ("gianfar: Add support for skb recycling"), gianfar puts skbuffs that are in the rx ring back onto the recycle list as-is in case there was a receive error, but this breaks the following invariant: that all skbuffs on the recycle list have skb->data = skb->head + NET_SKB_PAD. The RXBUF_ALIGNMENT realignment done in gfar_new_skb() will be done twice on skbuffs recycled in this way, causing there not to be enough room in the skb anymore to receive a full packet, eventually leading to an skb_over_panic from gfar_clean_rx_ring() -> skb_put(). Resetting the skb->data pointer to skb->head + NET_SKB_PAD before putting the skb back onto the recycle list restores the mentioned invariant, and should fix this issue.

| | | | | | | | | | | | | | | | | | | | cacheable_memzero() is completely overkill for the clearing out the FCB block which is only 8-bytes. The compiler should easily optimize this with memset. Additionally, cacheable_memzero() only exists on ppc32 and thus breaks builds of gianfar on ppc64. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: David S.
