| * wimax: Add netlink interface to get device statePaulius Zaleckas2009-05-295-1/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | wimax connection manager / daemon has to know what is current state of the device. Previously it was only possible to get notification whet state has changed. Note: By mistake, the new generic netlink's number for WIMAX_GNL_OP_STATE_GET was declared inserting into the existing list of API calls, not appending; thus, it'd break existing API. Fixed by Inaky Perez-Gonzalez <inaky@linux.intel.com> by moving to the tail, where we add to the interface, not modify the interface. Thanks to Stephen Hemminger <shemminger@vyatta.com> for catching this. Signed-off-by: Paulius Zaleckas <paulius.zaleckas@teltonika.lt>

| | | | | | | | | | | | | | | | | | | | For the overwhelming majority of cases, skb_gro_header's return value cannot be NULL. Yet we must check it because of its current form.

| | | | | | | | | | | | | | | | | | | | By caching frag0_len, we can avoid checking both frag0 and the length separately in skb_gro_header.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently skb_gro_header is used for packets which put the hardware header in skb->data with the rest in frags. Since the drivers that need this optimisation all provide completely non-linear packets, we can gain extra optimisations by only performing the frag0 optimisation for completely non-linear packets. In particular, we can simply test frag0 (instead of skb_headlen) to see whether the optimisation is in force. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | The function skb_gro_header is called four times per packet which quickly adds up at 10Gb/s. This patch inlines it to allow better optimisations. Some architectures perform multiplication for page_address, which is done by each skb_gro_header invocation. This patch caches that value in skb->cb to avoid the unnecessary multiplications.

* | gro: Open-code frags copy in skb_gro_receiveHerbert Xu2009-05-271-3/+6
| | | | | | | | | | | | | | | | | | | | | | gcc does a poor job at generating code for the memcpy of the frags array in skb_gro_receive, which is the primary purpose of that function when merging frags. In particular, it can't utilise the alignment information of the source and destination. This patch open-codes the copy so we process words instead of bytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We would like to get rid of netdev->trans_start = jiffies; that about all net drivers have to use in their start_xmit() function, and use txq->trans_start instead. This can be done generically in core network, as suggested by David. Some devices, (particularly loopback) dont need trans_start update, because they dont have transmit watchdog. We could add a new device flag, or rely on fact that txq->tran_start can be updated is txq->xmit_lock_owner is different than -1. Use a helper function to hide our choice.

Therefore, we have this layout: extra: +-------------------------+ | struct iw_encode_ext { | | ... | | u16 key_len; | | u8 key[0]; | | }; | +-------------------------+ | key material | +-------------------------+ Now, all drivers I checked use ext->key_len without checking that both key_len and the struct fit into the extra buffer that has been copied from userspace. This leads to a buffer overrun while reading that buffer, depending on the driver it may be possible to specify arbitrary key_len or it may need to be a proper length for the key algorithm specified. Thankfully, this is only exploitable by root, but root can actually cause a segfault or use kernel memory as a key (which you can even get back with siocgiwencode or siocgiwencodeext from the key buffer). Fix this by verifying that key_len fits into the buffer along with struct iw_encode_ext. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

Lukyanov found a regression in 2.6.29 and made a complete analysis found in http://bugzilla.kernel.org/show_bug.cgi?id=13339 Quoted here because its a perfect one : begin_of_quotation 2.6.29 patch has introduced flexible route cache rebuilding. Unfortunately the patch has at least one critical flaw, and another problem. rt_intern_hash calculates rthi pointer, which is later used for new entry insertion. The same loop calculates cand pointer which is used to clean the list. If the pointers are the same, rtable leak occurs, as first the cand is removed then the new entry is appended to it. This leak leads to unregister_netdevice problem (usage count > 0). Another problem of the patch is that it tries to insert the entries in certain order, to facilitate counting of entries distinct by all but QoS parameters. Unfortunately, referencing an existing rtable entry moves it to list beginning, to speed up further lookups, so the carefully built order is destroyed. For the first problem the simplest patch it to set rthi=0 when rthi==cand, but it will also destroy the ordering. end_of_quotation Problematic commit is 1080d709fb9d8cd4392f93476ee46a9d6ea05a5b (net: implement emergency route cache rebulds when gc_elasticity is exceeded) Trying to keep dst_entries ordered is too complex and breaks the fact that order should depend on the frequency of use for garbage collection. A possible fix is to make rt_intern_hash() simpler, and only makes rt_check_expire() a litle bit smarter, being able to cope with an arbitrary entries order. The added loop is running on cache hot data, while cpu is prefetching next object, so should be unnoticied. Reported-and-analyzed-by: Alexander V.

| * | | mac80211: correct probe wait timeJohannes Berg2009-05-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My first patch submission used 200ms, which I then somehow managed to revert back to the earlier 50ms I had used for some tests in the second patch submission -- but that was wrong, I should have used 200ms here. Correct that. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
| * | | mac80211: fix probe response wait timingJohannes Berg2009-05-221-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In "mac80211: split out and decrease probe wait time" I tried to reduce the time waiting for a probe response, but failed to take into account the case where we are detecting beacon loss in software -- in that case we still wait the monitoring time rather than the probe wait time. Fix this by refactoring the mod_timer() calls in ieee80211_associated(). Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
| * | | wext: remove atomic requirement for wireless statsJohannes Berg2009-05-221-5/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The requirement for wireless stats to be atomic is now mostly artificial since we hold the rtnl _and_ the dev_base_lock for iterating the device list. Doing that is not required, just the rtnl is sufficient (and the rtnl is required for other reasons outlined in commit "wext: fix get_wireless_stats locking"). This will fix http://bugzilla.kernel.org/show_bug.cgi?id=13344 and make things easier for drivers. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
