2018-06-13treewide: kzalloc() -> kcalloc()Kees Cook21-47/+54
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2018-06-06treewide: Use struct_size() for kmalloc()-familyKees Cook2-5/+3
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kmalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kmalloc(struct_size(instance, entry, count), GFP_KERNEL); This patch makes the changes for kmalloc()-family (and kvmalloc()-family) uses. It was done via automatic conversion with manual review for the "CHECKME" non-standard cases noted below, using the following Coccinelle script: // pkey_cache = kmalloc(sizeof *pkey_cache + tprops->pkey_tbl_len * // sizeof *pkey_cache->table, GFP_KERNEL); @@ identifier alloc =~ "kmalloc|kzalloc|kvmalloc|kvzalloc"; expression GFP; identifier VAR, ELEMENT; expression COUNT; @@ - alloc(sizeof(*VAR) + COUNT * sizeof(*VAR->ELEMENT), GFP) + alloc(struct_size(VAR, ELEMENT, COUNT), GFP) // mr = kzalloc(sizeof(*mr) + m * sizeof(mr->map[0]), GFP_KERNEL); @@ identifier alloc =~ "kmalloc|kzalloc|kvmalloc|kvzalloc"; expression GFP; identifier VAR, ELEMENT; expression COUNT; @@ - alloc(sizeof(*VAR) + COUNT * sizeof(VAR->ELEMENT[0]), GFP) + alloc(struct_size(VAR, ELEMENT, COUNT), GFP) // Same pattern, but can't trivially locate the trailing element name, // or variable name. @@ identifier alloc =~ "kmalloc|kzalloc|kvmalloc|kvzalloc"; expression GFP; expression SOMETHING, COUNT, ELEMENT; @@ - alloc(sizeof(SOMETHING) + COUNT * sizeof(ELEMENT), GFP) + alloc(CHECKME_struct_size(&SOMETHING, ELEMENT, COUNT), GFP) Signed-off-by: Kees Cook <keescook@chromium.org>

2018-05-30qtnfmac: fix invalid STA state on EAPOL failureSergey Matyukevich2-12/+17
Driver switches vif sta_state into QTNF_STA_CONNECTING when cfg80211 core initiates connect procedure. Further this state is changed either to QTNF_STA_CONNECTED or to QTNF_STA_DISCONNECTED by BSS_JOIN and BSS_LEAVE events from firmware. However it is possible that no such events will be sent by firmware, e.g. if EAPOL timed out. In this case vif sta_mode will remain in QTNF_STA_CONNECTING state and all subsequent connection attempts will fail with -EBUSY error code. Fix this by perfroming STA state transition from QTNF_STA_CONNECTING to QTNF_STA_DISCONNECTED in cfg80211 disconnect callback. No need to rely upon firmware events in this case.

2018-05-30qtnfmac: cleanup wdev structure between its usesSergey Matyukevich2-6/+3
Driver uses statically allocated wdev structures for each virtual interface. However wdev structure is not properly cleaned up between its uses. As a result, various bugs appear when userspace tools like hostapd were not gracefully stopped. In particular, this commit fixes the following issue: - start hostapd with more than 2 mBSS - kill hostapd using SIGKILL - start again hostapd with more than 2 mBSS However only two mBSS entities will be started: primary and the last BSS listed in hostapd config.

2018-05-30iwlwifi: mvm: fix race in queue notification waitJohannes Berg1-8/+8
Initially in this code, the race didn't matter since it didn't do anything. Latest with the commit I marked this as fixing it started to matter as something got done here that needed other data that got freed as soon as the queue notification wait was returning. In the scenario we saw, apparently the IWL_MVM_RXQ_NOTIF_DEL_BA event was sent to all queues, but processing the last event we returned from iwl_mvm_sync_rx_queues_internal() and then from iwl_mvm_free_reorder() and continued some processing before wl_mvm_del_ba() was even invoked on the other CPU. Thus, when the latter finally ran, it found that mvm->baid_map[baid] was no longer valid. Correct the race by moving the counter decrement and wake_up() to be done only after all the per-event processing completed. Note that in the commit I marked as being fixed the wake_up() didn't exist yet (and the code was otherwise problematic) but this particular problem already existed in a way.

2018-05-30iwlwifi: mvm: fix TSO with highly fragmented SKBsEmmanuel Grumbach1-6/+6
Our hardware has a limited amount of buffer descriptors for each Tx packet. Because of that, there is a short piece of code that makes sure that that we don't push too many subframes in an A-MSDU because of subframes needs 2 buffer descriptors. This code also takes into account the number of fragment of the skb since we also need a buffer descriptor for each fragment in the skb. This piece of code though didn't check that the resulting number of subframes wasn't 0. A user reported that using NFS client, he could get skbs that are so fragmented that the code mentioned above returned 0 for the number of subframes making skb_gso_segment fail and subconsequently iwlwifi would WARN. Fix this by make sure that num_subframes is at least 1.

This may happen in unsecured aggregation flow, where the first packet had a CRC error in the WEP bit, which was followed by a failure to decrypt and was dropped. The next frames in the aggregation "inherit" the bad metadata of the first packet. Make sure to drop such frames since RADA and other offloads will not operate correctly which may have unexpected results.

When there are 16 or more logical CPUs, we request for `IWL_MAX_RX_HW_QUEUES` (16) IRQs only as we limit to that number of IRQs, but later on we compare the number of IRQs returned to nr_online_cpus+2 instead of max_irqs, the latter being what we actually asked for. This ends up setting num_rx_queues to 17 which causes lots of out-of-bounds array accesses later on. Compare to max_irqs instead, and also add an assertion in case num_rx_queues > IWM_MAX_RX_HW_QUEUES.
