[ Upstream commit 1196364f ] calc_vmlinuz_load_addr.c requires SZ_64K to be defined for alignment purposes. It included "../../../../include/linux/sizes.h" to define that size, however "sizes.h" tries to include <linux/const.h> which assumes linux system headers. These may not exist eg. the following error was encountered when building Linux for OpenWrt under macOS: In file included from arch/mips/boot/compressed/calc_vmlinuz_load_addr.c:16: arch/mips/boot/compressed/../../../../include/linux/sizes.h:11:10: fatal error: 'linux/const.h' file not found ^~~~~~~~~~ Change makefile to force building on local linux headers instead of system headers. Also change eye-watering relative reference in include file spec. Thanks to Jo-Philip Wich & Petr Štetiar for assistance in tracking this down & fixing. Suggested-by:

commit ac6639cd upstream. Current code sets the dsci to 0x00000080. Which doesn't make any sense, as the indicator area is located in the _left-most_ byte. Worse: if the dsci is the _shared_ indicator, this potentially clears the indication of activity for a _different_ device. tiqdio_thinint_handler() will then have no reason to call that device's IRQ handler, and the device ends up stalling.

commit e54e4785 upstream. When tiqdio_remove_input_queues() removes a queue from the tiq_list as part of qdio_shutdown(), it doesn't re-initialize the queue's list entry and the prev/next pointers go stale. If a subsequent qdio_establish() fails while sending the ESTABLISH cmd, it calls qdio_shutdown() again in QDIO_IRQ_STATE_ERR state and tiqdio_remove_input_queues() will attempt to remove the queue entry a second time. This dereferences the stale pointers, and bad things ensue. Fix this by re-initializing the list entry after removing it from the list. For good practice also initialize the list entry when the queue is first allocated, and remove the quirky checks that papered over this omission. Note that prior to commit e5218134 ("s390/qdio: fix access to uninitialized qdio_q fields"), these checks were bogus anyway. setup_queues_misc() clears the whole queue struct, and thus needs to re-init the prev/next pointers as well.

commit 4f18d869 upstream. The stfle inline assembly returns the number of double words written (condition code 0) or the double words it would have written (condition code 3), if the memory array it got as parameter would have been large enough. The current stfle implementation assumes that the array is always large enough and clears those parts of the array that have not been written to with a subsequent memset call. If however the array is not large enough memset will get a negative length parameter, which means that memset clears memory until it gets an exception and the kernel crashes. To fix this simply limit the maximum length. Move also the inline assembly to an extra function to avoid clobbering of register 0, which might happen because of the added min_t invocation together with code instrumentation. The bug was introduced with commit 14375bc4 ("[S390] cleanup facility list handling") but was rather harmless, since it would only write to a rather large array. It became a potential problem with commit 3ab121ab ("[S390] kernel: Add z/VM LGR detection"). Since then it writes to an array with only four double words, while some machines already deliver three double words. As soon as machines have a facility bit within the fifth double a crash on IPL would happen.

commit 1c2eb5b2 upstream. The VMCI handle array has an integer overflow in vmci_handle_arr_append_entry when it tries to expand the array. This can be triggered from a guest, since the doorbell link hypercall doesn't impose a limit on the number of doorbell handles that a VM can create in the hypervisor, and these handles are stored in a handle array. In this change, we introduce a mandatory max capacity for handle arrays/lists to avoid excessive memory usage. Signed-off-by:

commit feb09b29 upstream. This patch follows Alan Stern's recent patch: "p54: Fix race between disconnect and firmware loading" that overhauled carl9170 buggy firmware loading and driver unbinding procedures. Since the carl9170 code was adapted from p54 it uses the same functions and is likely to have the same problem, but it's just that the syzbot hasn't reproduce them (yet). a summary from the changes (copied from the p54 patch): * Call usb_driver_release_interface() rather than device_release_driver(). * Lock udev (the interface's parent) before unbinding the driver instead of locking udev->parent. * During the firmware loading process, take a reference to the USB interface instead of the USB device. * Don't take an unnecessary reference to the device during probe (and then don't drop it during disconnect). and * Make sure to prevent use-after-free bugs by explicitly setting the driver context to NULL after signaling the completion.

commit 7379e6ba upstream. The interrupt handler `pci230_interrupt()` causes a null pointer dereference for a PCI260 card. There is no analog output subdevice for a PCI260. The `dev->write_subdev` subdevice pointer and therefore the `s_ao` subdevice pointer variable will be `NULL` for a PCI260. The following call near the end of the interrupt handler results in the null pointer dereference for a PCI260: comedi_handle_events(dev, s_ao); Fix it by only calling the above function if `s_ao` is valid. Note that the other uses of `s_ao` in the calls `pci230_handle_ao_nofifo(dev, s_ao);` and `pci230_handle_ao_fifo(dev, s_ao);` will never be reached for a PCI260, so they are safe.

commit b2357839 upstream. The old commit 6e4b74e4 ("usb: renesas: fix scheduling in atomic context bug") fixed an atomic issue by using workqueue for the shdmac dmaengine driver. However, this has a potential race condition issue between the work pending and usbhsg_ep_free_request() in gadget mode. When usbhsg_ep_free_request() is called while pending the queue, since the work_struct will be freed and then the work handler is called, kernel panic happens on process_one_work(). To fix the issue, if we could call cancel_work_sync() at somewhere before the free request, it could be easy. However, the usbhsg_ep_free_request() is called on atomic (e.g. f_ncm driver calls free request via gether_disconnect()). For now, almost all users are having "USB-DMAC" and the DMAengine driver can be used on atomic. So, this patch adds a workaround for a race condition to call the DMAengine APIs without the workqueue. This means we still have TODO on shdmac environment (SH7724), but since it doesn't have SMP, the race condition might not happen.

commit 6e41e225 upstream. The syzbot fuzzer found a bug in the p54 USB wireless driver. The issue involves a race between disconnect and the firmware-loader callback routine, and it has several aspects. One big problem is that when the firmware can't be loaded, the callback routine tries to unbind the driver from the USB _device_ (by calling device_release_driver) instead of from the USB _interface_ to which it is actually bound (by calling usb_driver_release_interface). The race involves access to the private data structure. The driver's disconnect handler waits for a completion that is signalled by the firmware-loader callback routine. As soon as the completion is signalled, you have to assume that the private data structure may have been deallocated by the disconnect handler -- even if the firmware was loaded without errors. However, the callback routine does access the private data several times after that point. Another problem is that, in order to ensure that the USB device structure hasn't been freed when the callback routine runs, the driver takes a reference to it. This isn't good enough any more, because now that the callback routine calls usb_driver_release_interface, it has to ensure that the interface structure hasn't been freed. Finally, the driver takes an unnecessary reference to the USB device structure in the probe function and drops the reference in the disconnect handler. This extra reference doesn't accomplish anything, because the USB core already guarantees that a device structure won't be deallocated while a driver is still bound to any of its interfaces. To fix these problems, this patch makes the following changes: Call usb_driver_release_interface() rather than device_release_driver(). Don't signal the completion until after the important information has been copied out of the private data structure, and don't refer to the private data at all thereafter. Lock udev (the interface's parent) before unbinding the driver instead of locking udev->parent. During the firmware loading process, take a reference to the USB interface instead of the USB device. Don't take an unnecessary reference to the device during probe (and then don't drop it during disconnect). Signed-off-by:

commit 63d7ef36 upstream. Per the 802.11 specification, vendor IEs are (at minimum) only required to contain an OUI. A type field is also included in ieee80211.h (struct ieee80211_vendor_ie) but doesn't appear in the specification. The remaining fields (subtype, version) are a convention used in WMM headers. Thus, we should not reject vendor-specific IEs that have only the minimum length (3 bytes) -- we should skip over them (since we only want to match longer IEs, that match either WMM or WPA formats). We can reject elements that don't have the minimum-required 3 byte OUI. While we're at it, move the non-standard subtype and version fields into the WMM structs, to avoid this confusion in the future about generic "vendor header" attributes.

commit 5858bdad upstream. The directory may have been removed when entering fscrypt_ioctl_set_policy(). If so, the empty_dir() check will return error for ext4 file system. ext4_rmdir() sets i_size = 0, then ext4_empty_dir() reports an error because 'inode->i_size < EXT4_DIR_REC_LEN(1) + EXT4_DIR_REC_LEN(2)'. If the fs is mounted with errors=panic, it will trigger a panic issue. Add the check IS_DEADDIR() to fix this problem.

commit 69ae4f6a upstream. A few places in mwifiex_uap_parse_tail_ies() perform memcpy() unconditionally, which may lead to either buffer overflow or read over boundary. This patch addresses the issues by checking the read size and the destination size at each place more properly. Along with the fixes, the patch cleans up the code slightly by introducing a temporary variable for the token size, and unifies the error path with the standard goto statement. Reported-by:

commit 685c9b77 upstream. Currently mwifiex_update_bss_desc_with_ie() implicitly assumes that the source descriptor entries contain the enough size for each type and performs copying without checking the source size. This may lead to read over boundary. Fix this by putting the source size check in appropriate places. Signed-off-by:

commit 993773d1 upstream. The index to access the threads tls array is controlled by userspace via syscall: sys_ptrace(), hence leading to a potential exploitation of the Spectre variant 1 vulnerability. The index can be controlled from: ptrace -> arch_ptrace -> do_get_thread_area. Fix this by sanitizing the user supplied index before using it to access the p->thread.tls_array. Signed-off-by:

commit fa33cdbf upstream. In some cases, using the 'truncate' command to extend a UDF file results in a mismatch between the length of the file's extents (specifically, due to incorrect length of the final NOT_ALLOCATED extent) and the information (file) length. The discrepancy can prevent other operating systems (i.e., Windows 10) from opening the file. Two particular errors have been observed when extending a file: 1. The final extent is larger than it should be, having been rounded up to a multiple of the block size. B. The final extent is not shorter than it should be, due to not having been updated when the file's information length was increased.

[ Upstream commit cf18cecc ] Some transceivers may comply with SFF-8472 even though they do not implement the Digital Diagnostic Monitoring (DDM) interface described in the spec. The existence of such area is specified by the 6th bit of byte 92, set to 1 if implemented. Currently, without checking this bit, bnx2x fails trying to read sfp module's EEPROM with the follow message: ethtool -m enP5p1s0f1 Cannot get Module EEPROM data: Input/output error Because it fails to read the additional 256 bytes in which it is assumed to exist the DDM data. This issue was noticed using a Mellanox Passive DAC PN 01FT738. The EEPROM data was confirmed by Mellanox as correct and similar to other Passive DACs from other manufacturers. Signed-off-by:

[ Upstream commit 9642fa73 ] Stopping external metadata arrays during resync/recovery causes retries, loop of interrupting and starting reconstruction, until it hit at good moment to stop completely. While these retries curr_mark_cnt can be small- especially on HDD drives, so subtraction result can be smaller than 0. However it is casted to uint without checking. As a result of it the status bar in /proc/mdstat while stopping is strange (it jumps between 0% and 99%). The real problem occurs here after commit 72deb455 ("block: remove CONFIG_LBDAF"). Sector_div() macro has been changed, now the divisor is casted to uint32. For db = -8 the divisior(db/32-1) becomes 0. Check if db value can be really counted and replace these macro by div64_u64() inline. Signed-off-by:
