2018-08-28clk: npcm7xx: fix memory allocationGustavo A. R. Silva1-2/+2
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 = kzalloc(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 = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); Notice that, currently, there is a bug during the allocation: sizeof(npcm7xx_clk_data) should be sizeof(*npcm7xx_clk_data) Fix this bug by using struct_size() in kzalloc() This issue was detected with the help of Coccinelle.

2018-08-28ARM: dts: omap4-droid4: Fix emmc errors seen on some devicesTony Lindgren1-1/+1
Otherwise we can get the following errors occasionally on some devices: mmc1: tried to HW reset card, got error -110 mmcblk1: error -110 requesting status mmcblk1: recovery failed! print_req_error: I/O error, dev mmcblk1, sector 14329 ... I have one device that hits this error almost on every boot, and another one that hits it only rarely with the other ones I've used behave without problems. I'm not sure if the issue is related to a particular eMMC card model, but in case it is, both of the machines with issues have: # cat /sys/class/mmc_host/mmc1/mmc1:0001/manfid \ /sys/class/mmc_host/mmc1/mmc1:0001/oemid \ /sys/class/mmc_host/mmc1/mmc1:0001/name 0x000045 0x0100 SEM16G and the working ones have: 0x000011 0x0100 016G92 Note that "ti,non-removable" is different as omap_hsmmc_reg_get() does not call omap_hsmmc_disable_boot_regulators() if no_regulator_off_init is set. And currently we set no_regulator_off_init only for "ti,non-removable" and not for "non-removable". It seems that we should have "non-removable" with some other mmc generic property behave in the same way instead of having to use a non-generic property. But let's fix the issue first.

2018-08-28mac80211: don't update the PM state of a peer upon a multicast frameEmmanuel Grumbach1-0/+1
I changed the way mac80211 updates the PM state of the peer. I forgot that we could also have multicast frames from the peer and that those frame should of course not change the PM state of the peer: A peer goes to power save when it needs to scan, but it won't send the broadcast Probe Request with the PM bit set. This made us mark the peer as awake when it wasn't and then Intel's firmware would fail to transmit because the peer is asleep according to its database. The driver warned about this and it looked like this: WARNING: CPU: 0 PID: 184 at /usr/src/linux-4.16.14/drivers/net/wireless/intel/iwlwifi/mvm/tx.c:1369 iwl_mvm_rx_tx_cmd+0x53b/0x860 CPU: 0 PID: 184 Comm: irq/124-iwlwifi Not tainted 4.16.14 #1 RIP: 0010:iwl_mvm_rx_tx_cmd+0x53b/0x860 Call Trace: iwl_pcie_rx_handle+0x220/0x880 iwl_pcie_irq_handler+0x6c9/0xa20 ? irq_forced_thread_fn+0x60/0x60 ? irq_thread_dtor+0x90/0x90 The relevant code that spits the WARNING is: case TX_STATUS_FAIL_DEST_PS: /* the FW should have stopped the queue and not * return this status */ WARN_ON(1); info->flags |= IEEE80211_TX_STAT_TX_FILTERED; This fixes https://bugzilla.kernel.org/show_bug.cgi?id=199967.

2018-08-28bpf: sockmap, decrement copied count correctly in redirect error caseJohn Fastabend1-23/+22
Currently, when a redirect occurs in sockmap and an error occurs in the redirect call we unwind the scatterlist once in the error path of bpf_tcp_sendmsg_do_redirect() and then again in sendmsg(). Then in the error path of sendmsg we decrement the copied count by the send size. However, its possible we partially sent data before the error was generated. This can happen if do_tcp_sendpages() partially sends the scatterlist before encountering a memory pressure error. If this happens we need to decrement the copied value (the value tracking how many bytes were actually sent to TCP stack) by the number of remaining bytes _not_ the entire send size. Otherwise we risk confusing userspace. Also we don't need two calls to free the scatterlist one is good enough. So remove the one in bpf_tcp_sendmsg_do_redirect() and then properly reduce copied by the number of remaining bytes which may in fact be the entire send size if no bytes were sent. To do this use bool to indicate if free_start_sg() should do mem accounting or not. Signed-off-by: John Fastabend <[email protected]> Signed-off-by: Daniel Borkmann <[email protected]>

2018-08-28nvme-fcloop: Fix dropped LS's to removed target portJames Smart1-1/+2
When a targetport is removed from the config, fcloop will avoid calling the LS done() routine thinking the targetport is gone. This leaves the initiator reset/reconnect hanging as it waits for a status on the Create_Association LS for the reconnect. Change the filter in the LS callback path. If tport null (set when failed validation before "sending to remote port"), be sure to call done. This was the main bug. But, continue the logic that only calls done if tport was set but there is no remoteport (e.g. case where remoteport has been removed, thus host doesn't expect a completion).

2018-08-28nvme-pci: add a memory barrier to nvme_dbbuf_update_and_check_eventMichal Wnukowski1-0/+8
In many architectures loads may be reordered with older stores to different locations. In the nvme driver the following two operations could be reordered: - Write shadow doorbell (dbbuf_db) into memory. - Read EventIdx (dbbuf_ei) from memory. This can result in a potential race condition between driver and VM host processing requests (if given virtual NVMe controller has a support for shadow doorbell). If that occurs, then the NVMe controller may decide to wait for MMIO doorbell from guest operating system, and guest driver may decide not to issue MMIO doorbell on any of subsequent commands. This issue is purely timing-dependent one, so there is no easy way to reproduce it. Currently the easiest known approach is to run "Oracle IO Numbers" (orion) that is shipped with Oracle DB: orion -run advanced -num_large 0 -size_small 8 -type rand -simulate \ concat -write 40 -duration 120 -matrix row -testname nvme_test Where nvme_test is a .lun file that contains a list of NVMe block devices to run test against. Limiting number of vCPUs assigned to given VM instance seems to increase chances for this bug to occur. On test environment with VM that got 4 NVMe drives and 1 vCPU assigned the virtual NVMe controller hang could be observed within 10-20 minutes. That correspond to about 400-500k IO operations processed (or about 100GB of IO read/writes). Orion tool was used as a validation and set to run in a loop for 36 hours (equivalent of pushing 550M IO operations). No issues were observed. That suggest that the patch fixes the issue.

Problem is that we leak the taken reference on the psock in that path.

2018-08-27bpf, sockmap: fix potential use after free in bpf_tcp_closeDaniel Borkmann1-1/+1
bpf_tcp_close() we pop the psock linkage to a map via psock_map_pop(). A parallel update on the sock hash map can happen between psock_map_pop() and lookup_elem_raw() where we override the element under link->hash / link->key. In bpf_tcp_close()'s lookup_elem_raw() we subsequently only test whether an element is present, but we do not test whether the element is infact the element we were looking for. We lock the sock in bpf_tcp_close() during that time, so do we hold the lock in sock_hash_update_elem(). However, the latter locks the sock which is newly updated, not the one we're purging from the hash table. This means that while one CPU is doing the lookup from bpf_tcp_close(), another CPU is doing the map update in parallel, dropped our sock from the hlist and released the psock. Subsequently the first CPU will find the new sock and attempts to drop and release the old sock yet another time. Fix is that we need to check the elements for a match after lookup, similar as we do in the sock map. Note that the hash tab elems are freed via RCU, so access to their link->hash / link->key is fine since we're under RCU read side there.

2018-08-27sctp: hold transport before accessing its asoc in sctp_transport_get_nextXin Long2-11/+15
As Marcelo noticed, in sctp_transport_get_next, it is iterating over transports but then also accessing the association directly, without checking any refcnts before that, which can cause an use-after-free Read. So fix it by holding transport before accessing the association. With that, sctp_transport_hold calls can be removed in the later places.

2018-08-27mtd: rawnand: denali: do not pass zero maxchips to nand_scan()Masahiro Yamada1-0/+5
Commit 49aa76b16676 ("mtd: rawnand: do not execute nand_scan_ident() if maxchips is zero") gave a new meaning for calling nand_scan_ident() with maxchips=0. It is a special usage for some drivers such as docg4, but actually the Denali driver may pass maxchips=0 to nand_scan() when the driver is enabled but no NAND chip is found on the board for some reasons. If nand_scan_with_ids() is called with maxchips=0, nand_scan_ident() is skipped, then nand_set_defaults() is skipped as well. Thus, the driver must set chip->controller beforehand. Otherwise, nand_attach() causes NULL pointer dereference. In fact, the Denali controller knows the number of connected chips before calling nand_scan_ident(); if DEVICE_RESET fails, there is no chip in that chip select. Then, denali_reset_banks() sets the maxchips to the number of detected chips. If no chip is found, maxchips is zero. In this case, there is no point for calling nand_scan() because we know it will fail for sure. Let's make the probe function fail immediately.
