commit de0c799b upstream. Seen while reading the code, in handle_mm_fault(), in the case arch_vma_access_permitted() is failing the call to mem_cgroup_oom_disable() is not made. To fix that, move the call to mem_cgroup_oom_enable() after calling arch_vma_access_permitted() as it should not have entered the memcg OOM.

commit 8606a1a9 upstream. If initializing a small swap file fails because the swap file has a problem (holes, etc.) then we need to free the cluster info as part of cleanup. Unfortunately a previous patch changed the code to use kvzalloc but did not change all the vfree calls to use kvfree. Found by running generic/357 from xfstests.

commit bc9ae224 upstream. __radix_tree_preload() only disables preemption if no error is returned. So we really need to make sure callers always check the return value. idr_preload() contract is to always disable preemption, so we need to add a missing preempt_disable() if an error happened. Similarly, ida_pre_get() only needs to call preempt_enable() in the case no error happened.

commit 6c6b5a39 upstream. Several distributions mount the "proper root" as ro during initrd and then remount it as rw before pivot_root(2). Thus, if a rescan had been aborted by a previous shutdown, the rescan would never be resumed. This issue would manifest itself as several btrfs ioctl(2)s causing the entire machine to hang when btrfs_qgroup_wait_for_completion was hit (due to the fs_info->qgroup_rescan_running flag being set but the rescan itself not being resumed). Notably, Docker's btrfs storage driver makes regular use of BTRFS_QUOTA_CTL_DISABLE and BTRFS_IOC_QUOTA_RESCAN_WAIT (causing this problem to be manifested on boot for some machines).

commit 3bff08df upstream. Commit a894cf6c ("mtd: nand: mxc: switch to mtd_ooblayout_ops") introduced a bug in the OOB layout description. Even if the driver claims that 3 ECC bytes are reserved to protect 512 bytes of data, it's actually 5 ECC bytes to protect 512+6 bytes of data (some OOB bytes are also protected using extra ECC bytes). Fix the mxc_v1_ooblayout_{free,ecc}() functions to reflect this behavior. Signed-off-by:

commit fd213b5b upstream. According to the datasheet of the H27UCG8T2BTR the NAND Technology field (6th byte of the "Device Identifier Description", bits 0-2) the following values are possible: - 0x0 = 48nm - 0x1 = 41nm - 0x2 = 32nm - 0x3 = 26nm - 0x4 = 20nm - (all others are reserved) Fix this by extending the mask for this field to allow detecting value 0x4 (20nm) as valid NAND technology. Without this the detection of the ECC requirements fails, because the code assumes that the device is a 48nm device (0x4 & 0x3 = 0x0) and aborts with "Invalid ECC requirements" because it cannot map the "ECC Level". Extending the mask makes the ECC requirement detection code recognize this chip as <= 26nm and sets up the ECC step size and ECC strength correctly. Signed-off-by:

commit 69fc0129 upstream. commit c51d0ac5 ("mtd: nand: Move Samsung specific init/detection logic in nand_samsung.c") introduced a regression for Samsung SLC NAND chips. Prior to this commit chip->bits_per_cell was initialized by calling nand_get_bits_per_cell() before using nand_is_slc(). With the offending commit this call is skipped, leaving chip->bits_per_cell cleared to zero when the manufacturer specific '.detect' function calls nand_is_slc() which in turn interprets bits_per_cell != 1 as indication for an MLC chip. The effect is that e.g. a K9F1G08U0F NAND chip is falsely detected as MLC NAND with 4KiB page size rather than SLC with 2KiB page size. Add a call to nand_get_bits_per_cell() before calling the .detect hook function in nand_manufacturer_detect(), so that the nand_is_slc() calls in the manufacturer specific code will return correct results.

commit 1d9b168d upstream. Commit f70e4df2 ("rtlwifi: Add code to read new versions of firmware") added code to load an old firmware file if the new one is not available. Unfortunately that code is never reached because request_firmware_nowait() does not wait for the firmware to show up and returns 0 even if the file is not there.

commit 08ab58d9 upstream. As of_device_get_modalias() returns the number of bytes that would have been written to the target string, regardless of how much did fit in the buffer, it's possible that the returned index points beyond the buffer passed to of_device_modalias() - causing memory beyond the buffer to be null terminated.

commit 8d26f491 upstream. Commit 1bc0eb04 ("scsi: sg: protect accesses to 'reserved' page array") adds needed concurrency protection for the "reserve" buffer. Some checks that are initially made outside the lock are replicated once the lock is taken to ensure the checks and resulting decisions are made using consistent state. The check that a request with flag SG_FLAG_MMAP_IO set fits in the reserve buffer also needs to be performed again under the lock to ensure the reserve buffer length compared against matches the value in effect when the request is linked to the reserve buffer. An -ENOMEM should be returned in this case, instead of switching over to an indirect buffer as for non-MMAP_IO requests. Signed-off-by:

commit fa41ba0d upstream. Right now there is a potential hang situation for postcopy migrations, if the guest is enabling storage keys on the target system during the postcopy process. For storage key virtualization, we have to forbid the empty zero page as the storage key is a property of the physical page frame. As we enable storage key handling lazily we then drop all mappings for empty zero pages for lazy refaulting later on. This does not work with the postcopy migration, which relies on the empty zero page never triggering a fault again in the future. The reason is that postcopy migration will simply read a page on the target system if that page is a known zero page to fault in an empty zero page. At the same time postcopy remembers that this page was already transferred - so any future userfault on that page will NOT be retransmitted again to avoid races. If now the guest enters the storage key mode while in postcopy, we will break this assumption of postcopy. The solution is to disable the empty zero page for KVM guests early on and not during storage key enablement. With this change, the postcopy migration process is guaranteed to start after no zero pages are left. As guest pages are very likely not empty zero pages anyway the memory overhead is also pretty small. While at it this also adds proper page table locking to the zero page removal. Signed-off-by:

commit 4b5dde2d upstream. mwifiex records information about various channels as it receives scan information. It does this by appending to a buffer that was sized to the max number of supported channels on any band, but there are numerous problems: (a) scans can return info from more than one band (e.g., both 2.4 and 5 GHz), so the determined "max" is not large enough (b) some firmware appears to return multiple results for a given channel, so the max *really* isn't large enough (c) there is no bounds checking when stashing these stats, so problems (a) and (b) can easily lead to buffer overflows Let's patch this by setting a slightly-more-correct max (that accounts for a combination of both 2.4G and 5G bands) and adding a bounds check when writing to our statistics buffer. Due to problem (b), we still might not properly report all known survey information (e.g., with "iw <dev> survey dump"), since duplicate results (or otherwise "larger than expected" results) will cause some truncation. But that's a problem for a future bugfix. (And because of this known deficiency, only log the excess at the WARN level, since that isn't visible by default in this driver and would otherwise be a bit too noisy.)

commit f35a7f91 upstream. The rx ring buffers are added to a hash table if firmware support full rx reorder. If the full rx reorder support flag is not set before allocating the rx ring buffers, none of the buffers are added to the hash table. There is a race condition between rx ring refill and rx buffer replenish from napi poll. The interrupts are enabled in hif start, before the rx ring is refilled during init. We replenish buffers from napi poll due to the interrupts which get enabled after hif start. Hence before the entire rx ring is refilled during the init, the napi poll replenishes a few buffers in steps of 100 buffers per attempt. During this rx ring replenish from napi poll, the rx reorder flag has not been set due to which the replenished buffers are not added to the hash table Set the rx full reorder support flag before we allocate the rx ring buffer to avoid the memory leak.
