2020-10-01iwlwifi: mvm: add an option to add PASN stationAvraham Stern6-6/+137
A FTM responder may do PASN authentication with unassociated stations to allow secure ranging. In this case, the driver will add an internal station and install the TK so the FW will accept protected FTM request frames from this station and will send a protected FTM response frame. In addition, the driver needs to configure the HLTK to the FW so the FW can derive the secure LTF bits. This is left for a later patch since it is not yet supported by the FW.

2020-10-01iwlwifi: msix: limit max RX queues for 9000 familyMordechay Goodstein2-1/+6
There is an issue in the HW DMA engine in the 9000 family of devices when more than 6 RX queues are used. The issue is that the FW may hang when IWL_MVM_RXQ_NSSN_SYNC notifications are sent.

2020-09-29net: iwlwifi: Remove in_interrupt() from tracing macro.Sebastian Andrzej Siewior2-5/+3
The usage of in_interrupt) in driver code is phased out. The iwlwifi_dbg tracepoint records in_interrupt() seperately, but that's superfluous because the trace header already records all kind of state and context information like hardirq status, softirq status, preemption count etc. Aside of that the recording of in_interrupt() as boolean does not allow to distinguish between the possible contexts (hard interrupt, soft interrupt, bottom half disabled) while the trace header gives precise information. Remove the duplicate information from the tracepoint and fixup the caller.

2020-09-29net: ipw2x00,iwlegacy,iwlwifi: Remove in_interrupt() from debug macrosSebastian Andrzej Siewior1-2/+1
The usage of in_interrupt() in non-core code is phased out. The debugging macros in these drivers use in_interrupt() to print 'I' or 'U' depending on the return value of in_interrupt(). While 'U' is confusing at best and 'I' is not really describing the actual context (hard interupt, soft interrupt, bottom half disabled section) these debug macros originate from the pre ftrace kernel era and their value today is questionable. They probably should be removed completely. The macros weere added initially for ipw2100 and then spreaded when the driver was forked. Remove the in_interrupt() usage at least..

2020-08-07mm, treewide: rename kzfree() to kfree_sensitive()Waiman Long3-7/+7
As said by Linus: A symmetric naming is only helpful if it implies symmetries in use. Otherwise it's actively misleading. In "kzalloc()", the z is meaningful and an important part of what the caller wants. In "kzfree()", the z is actively detrimental, because maybe in the future we really _might_ want to use that "memfill(0xdeadbeef)" or something. The "zero" part of the interface isn't even _relevant_. The main reason that kzfree() exists is to clear sensitive information that should not be leaked to other future users of the same memory objects. Rename kzfree() to kfree_sensitive() to follow the example of the recently added kvfree_sensitive() and make the intention of the API more explicit. In addition, memzero_explicit() is used to clear the memory to make sure that it won't get optimized away by the compiler. The renaming is done by using the command sequence: git grep -w --name-only kzfree |\ xargs sed -i 's/kzfree/kfree_sensitive/' followed by some editing of the kfree_sensitive() kerneldoc and adding a kzfree backward compatibility macro in slab.h.

2020-06-10iwlwifi: Replace zero-length array with flexible-arrayGustavo A. R. Silva5-11/+11
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

All iwlwifi cards below the 22000 series are able to handle multiple keyids per STA and allow the selection of the encryption key per MPDU. These are therefore fully compatible with the Extended Key ID support implementation in mac80211.

Range request version 10 keeps the same command size as version 9 but uses 2 reserved fields for the responder beacon interval and station id (if exists). For now, since the beacon interval of unassoc APs is unknown, use a value of 100 TUs which is a common value for many APs. While at it, remove the definition for CCMP_256 cipher, since this is not supported.

There are several "flavors" of HW that have the same HW type, but can be told apart after reading a certain perph register.
