* rsi: fix control-message timeoutJohan Hovold2021-11-121-1/+1
| | | | | | | | | | | | | | | | | commit 541fd20c3ce5b0bc39f0c6a52414b6b92416831c upstream. USB control-message timeouts are specified in milliseconds and should specifically not vary with CONFIG_HZ. Use the common control-message timeout define for the five-second timeout.

* media: staging/intel-ipu3: css: Fix wrong size comparison imgu_css_fw_initGustavo A. R. Silva2021-11-122-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit a44f9d6f9dc1fb314a3f1ed2dcd4fbbcc3d9f892 upstream. There is a wrong comparison of the total size of the loaded firmware css->fw->size with the size of a pointer to struct imgu_fw_header. Turn binary_header into a flexible-array member[1][2], use the struct_size() helper and fix the wrong size comparison. Notice that the loaded firmware needs to contain at least one 'struct imgu_fw_info' item in the binary_header[] array. It's also worth mentioning that "css->fw->size < struct_size(css->fwp, binary_header, 1)" with binary_header declared as a flexible-array member is equivalent to "css->fw->size < sizeof(struct imgu_fw_header)" with binary_header declared as a one-element array (as in the original code). The replacement of the one-element array with a flexible-array member also helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy().

* comedi: vmk80xx: fix bulk and interrupt message timeoutsJohan Hovold2021-11-121-5/+7
| | | | | | | | | | | | | | | | | | | | | | | commit a56d3e40bda460edf3f8d6aac00ec0b322b4ab83 upstream. USB bulk and interrupt message timeouts are specified in milliseconds and should specifically not vary with CONFIG_HZ. Note that the bulk-out transfer timeout was set to the endpoint bInterval value, which should be ignored for bulk endpoints and is typically set to zero. This meant that a failing bulk-out transfer would never time out. Assume that the 10 second timeout used for all other transfers is more than enough also for the bulk-out endpoint.

* comedi: vmk80xx: fix transfer-buffer overflowsJohan Hovold2021-11-121-2/+4

The driver uses endpoint-sized USB transfer buffers but up until recently had no sanity checks on the sizes. Commit e1f13c879a7c ("staging: comedi: check validity of wMaxPacketSize of usb endpoints found") inadvertently fixed NULL-pointer dereferences when accessing the transfer buffers in case a malicious device has a zero wMaxPacketSize. Make sure to allocate buffers large enough to handle also the other accesses that are done without a size check (e.g. byte 18 in vmk80xx_cnt_insn_read() for the VMK8061_MODEL) to avoid writing beyond the buffers, for example, when doing descriptor fuzzing. The original driver was for a low-speed device with 8-byte buffers. Support was later added for a device that uses bulk transfers and is presumably a full-speed device with a maximum 64-byte wMaxPacketSize.

* comedi: dt9812: fix DMA buffers on stackJohan Hovold2021-11-121-29/+86
| | | | | | | | | | | | | | | | | | | | | | commit 536de747bc48262225889a533db6650731ab25d3 upstream. USB transfer buffers are typically mapped for DMA and must not be allocated on the stack or transfers will fail. Allocate proper transfer buffers in the various command helpers and return an error on short transfers instead of acting on random stack data. Note that this also fixes a stack info leak on systems where DMA is not used as 32 bytes are always sent to the device regardless of how short the command is.

* binder: don't detect sender/target during buffer cleanupTodd Kjos2021-11-121-7/+7
| | | | | | | | | | | | | | | | | | | | | | | commit 32e9f56a96d8d0f23cb2aeb2a3cd18d40393e787 upstream. When freeing txn buffers, binder_transaction_buffer_release() attempts to detect whether the current context is the target by comparing current->group_leader to proc->tsk. This is an unreliable test. Instead explicitly pass an 'is_failure' boolean. Detecting the sender was being used as a way to tell if the transaction failed to be sent. When cleaning up after failing to send a transaction, there is no need to close the fds associated with a BINDER_TYPE_FDA object. Now 'is_failure' can be used to accurately detect this case.

It should be checking "read_pos + 4" because it's reading 5 bytes. If the "es_info_length" is non-zero then it reads a 6th byte so there needs to be an additional check for that. I also added checks for the "write_pos". I don't think these are required because "read_pos" and "write_pos" are tied together so checking one ought to be enough. But they make the code easier to understand for me. The check on write_pos is: if (write_pos + 4 >= sizeof(c->operand) - 4) { The first "+ 4" is because we're writing 5 bytes and the last " - 4" is to leave space for the CRC. The other problem is that "length" can be invalid. It comes from "data_length" in fdtv_ca_pmt().

This reverts commit 09e856d54bda5f288ef8437a90ab2b9b3eab83d1. When an interface is enslaved in a VRF, prerouting conntrack hook is called twice: once in the context of the original input interface, and once in the context of the VRF interface. If no special precausions are taken, this leads to creation of two conntrack entries instead of one, and breaks SNAT. Commit above was intended to avoid creation of extra conntrack entries when input interface is enslaved in a VRF. It did so by resetting conntrack related data associated with the skb when it enters VRF context. However it breaks netfilter operation. Imagine a use case when conntrack zone must be assigned based on the original input interface, rather than VRF interface (that would make original interfaces indistinguishable). One could create netfilter rules similar to these: chain rawprerouting { type filter hook prerouting priority raw; iif realiface1 ct zone set 1 return iif realiface2 ct zone set 2 return } This works before the mentioned commit, but not after: zone assignment is "forgotten", and any subsequent NAT or filtering that is dependent on the conntrack zone does not work. Here is a reproducer script that demonstrates the difference in behaviour. ========== #!/bin/sh # This script demonstrates unexpected change of nftables behaviour # caused by commit 09e856d54bda5f28 ""vrf: Reset skb conntrack # connection on VRF rcv" # https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=09e856d54bda5f288ef8437a90ab2b9b3eab83d1 # # Before the commit, it was possible to assign conntrack zone to a # packet (or mark it for `notracking`) in the prerouting chanin, raw # priority, based on the `iif` (interface from which the packet # arrived). # After the change, # if the interface is enslaved in a VRF, such # assignment is lost. Instead, assignment based on the `iif` matching # the VRF master interface is honored.

| | | | | | | | | | | | | | | | | | | | | | | commit f2b85040acec9a928b4eb1b57a989324e8e38d3f upstream. SCSI host release is triggered when SCSI device is freed. We have to make sure that the low-level device driver module won't be unloaded before SCSI host instance is released because shost->hostt is required in the release handler. Make sure to put LLD module refcnt after SCSI device is released. Fixes a kernel panic of 'BUG: unable to handle page fault for address' reported by Changhui and Yi.

* Revert "net: mdiobus: Fix memory leak in __mdiobus_register"Pavel Skripkin2021-11-021-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | commit 10eff1f5788b6ffac212c254e2f3666219576889 upstream. This reverts commit ab609f25d19858513919369ff3d9a63c02cd9e2e. This patch is correct in the sense that we _should_ call device_put() in case of device_register() failure, but the problem in this code is more vast. We need to set bus->state to UNMDIOBUS_REGISTERED before calling device_register() to correctly release the device in mdiobus_free(). This patch prevents us from doing it, since in case of device_register() failure put_device() will be called 2 times and it will cause UAF or something else. Also, Reported-by: tag in revered commit was wrong, since syzbot reported different leak in same function.

| | | | | | | | | | | | | | | | | | | commit 2195f2062e4cc93870da8e71c318ef98a1c51cef upstream. During probing, the driver tries to get a list (mask) of supported command types in port100_get_command_type_mask() function. The value is u64 and 0 is treated as invalid mask (no commands supported). The function however returns also -ERRNO as u64 which will be interpret as valid command mask. Return 0 on every error case of port100_get_command_type_mask(), so the probing will stop.

| | | | | | | | | | | | | | | | | commit a0023bb9dd9bc439d44604eeec62426a990054cd upstream. mv_init_host() propagates the value returned by mv_chip_id() which in turn gets propagated by mv_pci_init_one() and hits local_pci_probe(). During the process of driver probing, the probe function should return < 0 for failure, otherwise, the kernel will treat value > 0 as success. Since this is a bug rather than a recoverable runtime error we should use dev_alert() instead of dev_err().

| | | | | | | | | | | | | | | | | | | commit 6dba4bdfd7a30e77b848a45404b224588bf989e5 upstream. This reverts commit a49d784d5a8272d0f63c448fe8dc69e589db006e. The updated binding was wrong / invalid and has been reverted. There isn't any upstream kernel DTS using it and Broadcom isn't known to use it neither. There is close to zero chance this will cause regression for anyone. Actually in-kernel bcm5301x.dtsi still uses the old good binding and so it's broken since the driver update. This revert fixes it.
