2022-07-23SUNRPC: Introduce xdr_stream_move_subsegment()Anna Schumaker1-0/+59
I do this by creating an xdr subsegment for the range we will be operating over. This lets me shift data to the correct place without potentially overwriting anything already there.

2022-07-23SUNRPC: Fail faster on bad verifierChuck Lever1-1/+1
A bad verifier is not a garbage argument, it's an authentication failure. Retrying it doesn't make the problem go away, and delays upper layer recovery steps.

2022-07-22Bluetooth: ISO: Add broadcast supportLuiz Augusto von Dentz1-34/+357
This adds broadcast support for BTPROTO_ISO by extending the sockaddr_iso with a new struct sockaddr_iso_bc where the socket user can set the broadcast address when receiving, the SID and the BIS indexes it wants to synchronize. When using BTPROTO_ISO for broadcast the roles are: Broadcaster -> uses connect with address set to BDADDR_ANY: > tools/isotest -s 00:00:00:00:00:00 Broadcast Receiver -> uses listen with address set to broadcaster: > tools/isotest -d 00:AA:01:00:00:00 Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

2022-07-22Revert "tcp: change pingpong threshold to 3"Wei Wang1-9/+6
This reverts commit 4a41f453bedfd5e9cd040bad509d9da49feb3e2c. This to-be-reverted commit was meant to apply a stricter rule for the stack to enter pingpong mode. However, the condition used to check for interactive session "before(tp->lsndtime, icsk->icsk_ack.lrcvtime)" is jiffy based and might be too coarse, which delays the stack entering pingpong mode. We revert this patch so that we no longer use the above condition to determine interactive session, and also reduce pingpong threshold to 1.

Because of how struct msghdr is usually initialised some fields and sg_from_iter in particular might be left out not initialised, so we can't safely use it in __zerocopy_sg_from_iter().

In MLO we shouldn't call ieee80211_bss_info_change_notify(), call that only (for backward compatibility) without MLO, and otherwise ieee80211_vif_cfg_change_notify().

2022-07-22wifi: mac80211: optionally implement MLO multicast TXJohannes Berg4-11/+87
For drivers using software encryption for multicast TX, such as mac80211_hwsim, mac80211 needs to duplicate the multicast frames on each link, if MLO is enabled. Do this, but don't just make it dependent on the key but provide a separate flag for drivers to opt out of this. This is not very efficient, I expect that drivers will do it in firmware/hardware or at least with DMA engine assistence, so this is mostly for hwsim. To make this work, also implement the SNS11 sequence number space that an AP MLD shall have, and modify the API to the __ieee80211_subif_start_xmit() function to always require the link ID bits to be set.

2022-07-22wifi: mac80211: expand ieee80211_mgmt_tx() for MLOJohannes Berg5-24/+48
There are a couple of new things that should be possible with MLO: * selecting the link to transmit to a station by link ID, which a previous patch added to the nl80211 API * selecting the link by frequency, similarly * allowing transmittion to an MLD without specifying any channel or link ID, with MLD addresses Enable these use cases.

2022-07-22wifi: mac80211: validate link address doesn't changeJohannes Berg1-6/+12
When modifying a link station, validate that the link address doesn't change, except the first time the link is created. Fixes: b95eb7f0eee4 ("wifi: cfg80211/mac80211: separate link params from station params") Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-22wifi: mac80211: mlme: set sta.mlo to mlo stateJohannes Berg1-2/+2
At this point, we've already changed link_id to be zero for a non-MLO connection, so use the 'mlo' variable rather than link ID to determine the MLO status of the station. Fixes: bd363ee53302 ("wifi: mac80211: mlme: set sta.mlo correctly") Fixes: 81151ce462e5 ("wifi: mac80211: support MLO authentication/association with one link") Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-22wifi: mac80211: fast-xmit: handle non-MLO clientsJohannes Berg1-1/+15
If there's a non-MLO client, the A2 must be set to the BSSID of the link since no translation will happen in lower layers and it's needed that way for encryption. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-22wifi: mac80211: fix RX MLD address translationJohannes Berg1-4/+8
We should only translate addr3 here if it's the BSSID. Fixes: 42fb9148c078 ("wifi: mac80211: do link->MLD address translation on RX") Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-22wifi: mac80211: fix NULL pointer deref with non-MLD STAJohannes Berg1-1/+6
If we have a non-MLD STA on an AP MLD, we crash while adding the station. Fix that, in this case we need to use the STA's address also on the link data structure. Fixes: f36fe0a2df03 ("wifi: mac80211: fix up link station creation/insertion") Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-22wifi: mac80211: mlme: fix override calculationJohannes Berg1-0/+2
In my previous changes here, I neglected to take the old conn_flags into account that might still be present from the authentication, and thus ieee80211_setup_assoc_link() can misbehave, as well as the override calculation being wrong. Fix that by ORing in the old flags. Fixes: 1845c1d4a455 ("wifi: mac80211: mlme: refactor assoc link setup") Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-22wifi: mac80211: tx: use AP address in some places for MLOJohannes Berg2-5/+7
In a few places we need to use the AP (MLD) address, not the deflink BSSID, the link address translation will happen later. To make that work properly for fast-xmit, set up the ap_addr in the vif.cfg earlier. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Bitmap are "unsigned long", so use it instead of a "u32" to make things more explicit. While at it, remove some useless cast (and leading spaces) when using the bitmap API. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-07-22ping: support ipv6 ping socket flow labelsAlan Brady1-1/+5
Ping sockets don't appear to make any attempt to preserve flow labels created and set by userspace using IPV6_FLOWINFO_SEND. Instead they are clobbered by autolabels (if enabled) or zero. Grab the flowlabel out of the msghdr similar to how rawv6_sendmsg does it and move the memset up so it doesn't get zeroed after.
