2010-08-27iwlagn: always send RXON timingJohannes Berg
The PAN context requires also getting RXON timing when we send an unassociated RXON in some cases. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: pass context to iwl_send_rxon_timingJohannes Berg
Sometimes we need to send RXON timing even when we don't have a virtual interface yet, so pass the context and allow passing one without a virtual interface pointer. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: send PAN parametersJohannes Berg
In order for the microcode to be able to handle multiple interfaces, we need to give it the PAN parameters that state how to allocate the time between the two interfaces. Do this, and update it wherever necessary. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlagn: send beacon before committing associated RXONJohannes Berg
Newer AGN microcode requires know the beacon before starting the AP so that it can start beaconing right away. Implement that. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlagn: send RXON timing before associatingJohannes Berg
The PAN functionality requires us to send the timing including a valid DTIM period to the microcode before associating, so request this data from mac80211 and send it to the device. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlagn: queue frames according to contextJohannes Berg
Frames for different contexts need to be put on different queues, and multicast after DTIM frames have a special queue yet which also depends on the context, so put all this into the context. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlagn: remove iw_mode check for beaconJohannes Berg
Since we have the beacon context now, we no longer need to rely on iw_mode but can check the beacon context interface's type. However, that check must be in the work item instead due to locking constraints (mutex must be held when dereferencing beacon_ctx pointer). Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlagn: detect PAN capabilityJohannes Berg
Detect whether or not the ucode is PAN capable and adjust the valid contexts accordingly. To be able to do this, add the PAN context to the array as well. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: add PAN APIJohannes Berg
Define the new host commands and notifications REPLY_WIPAN_PARAMS REPLY_WIPAN_RXON REPLY_WIPAN_RXON_TIMING REPLY_WIPAN_RXON_ASSOC REPLY_WIPAN_QOS_PARAM REPLY_WIPAN_WEPKEY REPLY_WIPAN_P2P_CHANNEL_SWITCH REPLY_WIPAN_NOA_NOTIFICATION and their corresponding structures along with the PAN station flag, the PAN AP sta ID and new dev types for the second context. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: introduce beacon contextJohannes Berg
Only one context can be beaconing at a time, but we need to track which one. Introduce a new variable priv->beacon_ctx to do that. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: move HT configuration data into contextJohannes Berg
A lot of HT configuration semantically belongs into the context, even if right now it will never be different between contexts. Move it so we're better prepared for future changes in mac80211. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: add context pointer to stationJohannes Berg
Sometimes we only pass around station pointers but need to find the context they belong to, so store it in there. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: store default station flags in contextJohannes Berg
Since the default context is initialised to zero, and the default flags are zero, no more code is needed to initialise them right now, but another context can have different default flags. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: make hw crypto context awareJohannes Berg
HW crypto needs to be aware of the context, and there are different command IDs for the WEP keys per context, so move the key tracking variables and command IDs into the context structure. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: move AP sta ID to contextJohannes Berg
Each context needs to use a different AP sta ID, so we need to move that into the context struct instead of hardcoding it. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: clamp scanning dwell time to all contextsJohannes Berg
The dwell time should at least fit into all context's beacon intervals. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: move virtual interface pointer into contextJohannes Berg
iwlwifi occasionally needs to find the virtual interface pointer to give it to mac80211, but right now it only keeps one. Move it into the context so that we can keep one pointer each. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: add context into tx descriptorJohannes Berg
In status processing we'll need to find the context for a given frame, so add a context pointer to the TX info for each frame. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: move QoS into contextJohannes Berg
Since mac80211 doesn't currently enable/disable QoS per interface, we can't yet do it properly, but we can already prepare for it and move the QoS data and command ID into the context struct. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: contextify command sendingJohannes Berg
Some commands will have different command IDs for different contexts, so we need to store those IDs in the context structure and use them instead of hardcoding the commands. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: contextify-stations-completelyJohannes Berg
The microcode tracks stations per context, so the driver needs to do that as well for adding, deleting and restoring them, especially in the implicit removal case when we send an RXON. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: contextify broadcast stationJohannes Berg
The broadcast station ID is per context, so add a variable for the ID in the context and use it everywhere we previously hardcoded it. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27eCryptfs: Fix encrypted file name lookup regressionTyler Hicks
Fixes a regression caused by 21edad32205e97dc7ccb81a85234c77e760364c8 When file name encryption was enabled, ecryptfs_lookup() failed to use the encrypted and encoded version of the upper, plaintext, file name when performing a lookup in the lower file system. This made it impossible to lookup existing encrypted file names and any newly created files would have plaintext file names in the lower file system. https://bugs.launchpad.net/ecryptfs/+bug/623087 Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
2010-08-27ecryptfs: properly mark init functionsJerome Marchand
Some ecryptfs init functions are not prefixed by __init and thus not freed after initialization. This patch saved about 1kB in ecryptfs module. Signed-off-by: Jerome Marchand <jmarchan@redhat.com> Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
2010-08-27fs/ecryptfs: Return -ENOMEM on memory allocation failureJulia Lawall
In this code, 0 is returned on memory allocation failure, even though other failures return -ENOMEM or other similar values. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression ret; expression x,e1,e2,e3; @@ ret = 0 ... when != ret = e1 *x = \(kmalloc\|kcalloc\|kzalloc\)(...) ... when != ret = e2 if (x == NULL) { ... when != ret = e3 return ret; } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
2010-08-27iwlwifi: define PAN queues/FIFOsJohannes Berg
PAN capable microcode has a different queue assignment (not just more queues for PAN) due to the way multicast is handled for AP mode. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: prepare for PAN queue/fifo assignmentJohannes Berg
PAN ucode will require a different queue assignment, in particular queue 9 instead of 4 should be used for commands. This is required because the ucode will stop/start queues 4 and 8 depending on the PAN state, since queue 8 will be used for PAN multicast (after DTIM).

2010-08-27iwlwifi: initial contextificationJohannes Berg
In order to support multiple interfaces, we must move a lot of data into per-context structures so we can use the contexts the device offers. To start with, this makes a lot of code context-aware, more changes will move more things into the context structure.
