2023-04-19wifi: iwlwifi: dvm: Fix memcpy: detected field-spanning write backtraceHans de Goede1-1/+4
A received TKIP key may be up to 32 bytes because it may contain MIC rx/tx keys too. These are not used by iwl and copying these over overflows the iwl_keyinfo.key field. Add a check to not copy more data to iwl_keyinfo.key then will fit. This fixes backtraces like this one: memcpy: detected field-spanning write (size 32) of single field "sta_cmd.key.key" at drivers/net/wireless/intel/iwlwifi/dvm/sta.c:1103 (size 16) WARNING: CPU: 1 PID: 946 at drivers/net/wireless/intel/iwlwifi/dvm/sta.c:1103 iwlagn_send_sta_key+0x375/0x390 [iwldvm] <snip> Hardware name: Dell Inc.

2022-09-28wifi: iwlwifi: Track scan_cmd allocation size explicitlyKees Cook2-2/+9
In preparation for reducing the use of ksize(), explicitly track the size of scan_cmd allocations. This also allows for noticing if the scan size changes unexpectedly. Note that using ksize() was already incorrect here, in the sense that ksize() would not match the actual allocation size, which would trigger future run-time allocation bounds checking. (In other words, memset() may know how large scan_cmd was allocated for, but ksize() will return the upper bounds of the actually allocated memory, causing a run-time warning about an overflow.)

2022-09-07wifi: iwlwifi: calib: Refactor iwl_calib_result usage for clarityKees Cook3-15/+17
In preparation for FORTIFY_SOURCE performing run-time destination buffer bounds checking for memcpy(), refactor the use of struct iwl_calib_result: - Have struct iwl_calib_result contain struct iwl_calib_cmd since functions expect to operate on the "data" flex array in "cmd", which follows the "hdr" member. - Switch argument passing around to use struct iwl_calib_cmd instead of struct iwl_calib_hdr to prepare functions to see the "data" member. - Change iwl_calib_set()'s "len" argument to a size_t since it is always unsigned and is normally receiving the output of sizeof(). - Add an explicit length sanity check in iwl_calib_set(). - Adjust the memcpy() to avoid copying across the now visible composite flex array structure.

2022-04-11mac80211: prepare sta handling for MLO supportSriram R3-14/+14
Currently in mac80211 each STA object is represented using sta_info datastructure with the associated STA specific information and drivers access ieee80211_sta part of it. With MLO (Multi Link Operation) support being added in 802.11be standard, though the association is logically with a single Multi Link capable STA, at the physical level communication can happen via different advertised links (uniquely identified by Channel, operating class, BSSID) and hence the need to handle multiple link STA parameters within a composite sta_info object called the MLD STA. The different link STA part of MLD STA are identified using the link address which can be same or different as the MLD STA address and unique link id based on the link vif. To support extension of such a model, the sta_info datastructure is modified to hold multiple link STA objects with link specific params currently within sta_info moved to this new structure. Similarly this is done for ieee80211_sta as well which will be accessed within mac80211 as well as by drivers, hence trivial driver changes are expected to support this. For current non MLO supported drivers, only one link STA is present and link information is accessed via 'deflink' member. For MLO drivers, we still need to define the APIs etc. to get the correct link ID and access the correct part of the station info. Currently in mac80211, all link STA info are accessed directly via deflink. These will be updated to access via link pointers indexed by link id with MLO support patches, with link id being 0 for non MLO supported cases. Except for couple of macro related changes, below spatch takes care of updating mac80211 and driver code to access to the link STA info via deflink. @ieee80211_sta@ struct ieee80211_sta *s; struct sta_info *si; identifier var = {supp_rates, ht_cap, vht_cap, he_cap, he_6ghz_capa, eht_cap, rx_nss, bandwidth, txpwr}; @@ ( s-> - var + deflink.var | si->sta. - var + deflink.var ) @sta_info@ struct sta_info *si; identifier var = {gtk, pcpu_rx_stats, rx_stats, rx_stats_avg, status_stats, tx_stats, cur_max_bandwidth}; @@ ( si-> - var + deflink.var ) Signed-off-by: Sriram R <[email protected]> Link: https://lore.kernel.org/r/[email protected] [remove MLO-drivers notes from commit message, not clear yet; run spatch] Signed-off-by: Johannes Berg <[email protected]>

2021-12-07iwlwifi: support 4-bits in MAC step valueMike Golant1-6/+2
We have a MAC component (which is inside the SoC) and it has several different HW steps. 3 bits used to be enough but now we need 4-bits to represent all the different steps. Properly support 4-bits in the MAC step value by refactoring all the current handling of the MAC step/dash. Already from family 8000 and up the dash (bits 0-1) no longer exists and the step (until 8000 bits 2-3) consists of the dash bits as well. To do this remove the CSR_HW_REV_STEP and the CSR_HW_REV_DASH macros, replace them with CSR_HW_REV_STEP_DASH and add hw_rev_step into the trans struct. In addition remove the CSR_HW_IF_CONFIG_REG_MSK_MAC_STEP and CSR_HW_IF_CONFIG_REG_MSK_MAC_DASH macros and create a new macro combining the 2 (this way we don't need shifting or anything else.)

2020-06-10iwlwifi: Replace zero-length array with flexible-arrayGustavo A. R. Silva1-6/+6
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.

2020-06-05iwlwifi: Extended Key ID support for mvm and dvmAlexander Wetzel1-0/+1
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. Enable Extended Key ID support for all dvm cards and the mvm cards not using the incompatible new Tx API introduced for the 22000 series.

2020-04-24mac80211: populate debugfs only after cfg80211 initJohannes Berg1-1/+1
When fixing the initialization race, we neglected to account for the fact that debugfs is initialized in wiphy_register(), and some debugfs things went missing (or rather were rerooted to the global debugfs root). Fix this by adding debugfs entries only after wiphy_register(). This requires some changes in the rate control code since it currently adds debugfs at alloc time, which can no longer be done after the reordering.

2020-01-04iwlwifi: add device name to device_infoLuca Coelho1-2/+2
We have a lot of mostly duplicated data structures that are repeated only because the device name string is different. To avoid this, move the string from the cfg to the trans structure and add it independently from the rest of the configuration to the PCI mapping tables.

2019-12-23iwlwifi: pcie: allocate smaller dev_cmd for TX headersJohannes Berg1-2/+1
As noted in the previous commit, due to the way we allocate the dev_cmd headers with 324 byte size, and 4/8 byte alignment, the part we use of them (bytes 20..40-68) could still cross a page and thus 2^32 boundary. Address this by using alignment to ensure that the allocation cannot cross a page boundary, on hardware that's affected. To make that not cause more memory consumption, reduce the size of the allocations to the necessary size - we go from 324 bytes in each allocation to 60/68 on gen2 depending on family, and ~120 or so on gen1 (so on gen1 it's a pure reduction in size, since we don't need alignment there). To avoid size and clearing issues, add a new structure that's just the header, and use kmem_cache_zalloc().
