commit fee05f45 upstream. req.gid can be indirectly controlled by user-space, hence leading to a potential exploitation of the Spectre variant 1 vulnerability. This issue was detected with the help of Smatch: vers/misc/sgi-gru/grukdump.c:200 gru_dump_chiplet_request() warn: potential spectre issue 'gru_base' [w] Fix this by sanitizing req.gid before calling macro GID_TO_GRU, which uses it to index gru_base. Notice that given that speculation windows are large, the policy is to kill the speculation on the first load and not worry if it can be completed with a dependent load/store [1].

commit 7c973012 upstream. After building the kernel with Clang, the following section mismatch warning appears: WARNING: vmlinux.o(.text+0x3bf19a6): Section mismatch in reference from the function ssc_probe() to the function .init.text:atmel_ssc_get_driver_data() The function ssc_probe() references the function __init atmel_ssc_get_driver_data(). This is often because ssc_probe lacks a __init annotation or the annotation of atmel_ssc_get_driver_data is wrong. Remove __init from atmel_ssc_get_driver_data to get rid of the mismatch.

commit deefd242 upstream. Raydium USB touchscreen fails to set config if LPM is enabled: [ 2.030658] usb 1-8: New USB device found, idVendor=2386, idProduct=3119 [ 2.030659] usb 1-8: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 2.030660] usb 1-8: Product: Raydium Touch System [ 2.030661] usb 1-8: Manufacturer: Raydium Corporation [ 7.132209] usb 1-8: can't set config #1, error -110 Same behavior can be observed on 2386:3114. Raydium claims the touchscreen supports LPM under Windows, so I used Microsoft USB Test Tools (MUTT) [1] to check its LPM status. MUTT shows that the LPM doesn't work under Windows, either. So let's just disable LPM for Raydium touchscreens. [1] https://docs.microsoft.com/en-us/windows-hardware/drivers/usbcon/usb-test-toolsSigned-off-by:

commit 43279819 upstream. I was trying to solve a double free but I introduced a more serious NULL dereference bug. The problem is that if there is an IRQ which triggers immediately, then we need "info->uio_dev" but it's not set yet. This patch puts the original initialization back to how it was and just sets info->uio_dev to NULL on the error path so it should solve both the Oops and the double free.

commit 92539d3e upstream. Patch ad608fbc changed how events were subscribed to address an issue elsewhere. As a side effect of that change, the "add" callback was called before the event subscription was added to the list of subscribed events, causing the first event queued by the add callback (and possibly other events arriving soon afterwards) to be lost. Fix this by adding the subscription to the list before calling the "add" callback, and clean up afterwards if that fails. Fixes: ad608fbc ("media: v4l: event: Prevent freeing event subscriptions while accessed") Reported-by:

Commit 6ba9fc8e upstream. [BUG] fstrim on some btrfs only trims the unallocated space, not trimming any space in existing block groups. [CAUSE] Before fstrim_range passed to btrfs_trim_fs(), it gets truncated to range [0, super->total_bytes). So later btrfs_trim_fs() will only be able to trim block groups in range [0, super->total_bytes). While for btrfs, any bytenr aligned to sectorsize is valid, since btrfs uses its logical address space, there is nothing limiting the location where we put block groups. For filesystem with frequent balance, it's quite easy to relocate all block groups and bytenr of block groups will start beyond super->total_bytes. In that case, btrfs will not trim existing block groups. [FIX] Just remove the truncation in btrfs_ioctl_fitrim(), so btrfs_trim_fs() can get the unmodified range, which is normally set to [0, U64_MAX]. Reported-by:

Commit 93bba24d upstream. Function btrfs_trim_fs() doesn't handle errors in a consistent way. If error happens when trimming existing block groups, it will skip the remaining blocks and continue to trim unallocated space for each device. The return value will only reflect the final error from device trimming. This patch will fix such behavior by: 1) Recording the last error from block group or device trimming The return value will also reflect the last error during trimming. Make developer more aware of the problem. 2) Continuing trimming if possible If we failed to trim one block group or device, we could still try the next block group or device. 3) Report number of failures during block group and device trimming It would be less noisy, but still gives user a brief summary of what's going wrong. Such behavior can avoid confusion for cases like failure to trim the first block group and then only unallocated space is trimmed. Reported-by:

[ Upstream commit a0a37862 ] WDAT table on Lenovo Z50-70 is using RTC SRAM (ports 0x70 and 0x71) to store state of the timer. This conflicts with Linux RTC driver (rtc-cmos.c) who fails to reserve those ports for itself preventing RTC from functioning. In addition the WDAT table seems not to be fully functional because it does not reset the system when the watchdog times out. On this system iTCO_wdt works just fine so we simply prefer to use it instead of WDAT. This makes RTC working again and also results working watchdog via iTCO_wdt. Reported-by:

commit 10283ea5 upstream. gfs2_put_super calls gfs2_clear_rgrpd to destroy the gfs2_rgrpd objects attached to the resource group glocks. That function should release the buffers attached to the gfs2_bitmap objects (bi_bh), but the call to gfs2_rgrp_brelse for doing that is missing. When gfs2_releasepage later runs across these buffers which are still referenced, it refuses to free them. This causes the pages the buffers are attached to to remain referenced as well. With enough mount/unmount cycles, the system will eventually run out of memory. Fix this by adding the missing call to gfs2_rgrp_brelse in gfs2_clear_rgrpd. (Also fix a gfs2_rgrp_relse -> gfs2_rgrp_brelse typo in a comment.) Fixes: 39b0f1e9 ("GFS2: Don't brelse rgrp buffer_heads every allocation") Cc: stable@vger.kernel.org # v4.9 Signed-off-by:

[ Upstream commit bd74a7f9 ] Sniffing mode for L3 HiperSockets requires that no IP addresses are registered with the HW. The preferred way to achieve this is for userspace to delete all the IPs on the interface. But qeth is expected to also tolerate a configuration where that is not the case, by skipping the IP registration when in sniffer mode. Since commit 5f78e29c ("qeth: optimize IP handling in rx_mode callback") reworked the IP registration logic in the L3 subdriver, this no longer works. When the qeth device is set online, qeth_l3_recover_ip() now unconditionally registers all unicast addresses from our internal IP table. While we could fix this particular problem by skipping qeth_l3_recover_ip() on a sniffer device, the more future-proof change is to skip the IP address registration at the lowest level. This way we a) catch any future code path that attempts to register an IP address without considering the sniffer scenario, and b) continue to build up our internal IP table, so that if sniffer mode is switched off later we can operate just like normal.

While it's not strictly wrong, the BUILD_BUG will prevent this from becoming a true problem. Initialize ret to 0 in the default case right before the BUILD_BUG to silence all of these warnings.

As can be seen in the context, the BIOS registers haven't changed in the previous versions, so the assumption is they won't have changed in this last update for this somewhat older platform either.

[ Upstream commit 8d98b1ef ] On some Goldmont based systems such as ASRock J3455M the BIOS may not enable the IPC1 device that provides access to the PMC and PUNIT. In such scenarios, the IOSS and PSS resources from the platform device can not be obtained and result in a invalid telemetry_plt_config which is an internal data structure that holds platform config and is maintained by the telemetry platform driver. This is also applicable to the platforms where the BIOS supports IPC1 device under debug configurations but IPC1 is disabled by user or the policy. This change allows user to know the reason for not seeing entries under /sys/kernel/debug/telemetry/* when there is no apparent failure at boot.

[ Upstream commit 0a3021d4 ] Creating, renaming or deleting a file may cause catalog corruption and data loss. This bug is randomly triggered by xfstests generic/027, but here is a faster reproducer: truncate -s 50M fs.iso mkfs.hfsplus fs.iso mount fs.iso /mnt i=100 while [ $i -le 150 ]; do touch /mnt/$i &>/dev/null ((++i)) done i=100 while [ $i -le 150 ]; do mv /mnt/$i /mnt/$(perl -e "print $i x82") &>/dev/null ((++i)) done umount /mnt fsck.hfsplus -n fs.iso The bug is triggered whenever hfs_brec_update_parent() needs to split the root node. The height of the btree is not increased, which leaves the new node orphaned and its records lost.

[ Upstream commit d057c036 ] This bug is triggered whenever hfs_brec_update_parent() needs to split the root node. The height of the btree is not increased, which leaves the new node orphaned and its records lost. It is not possible for this to happen on a valid hfs filesystem because the index nodes have fixed length keys. For reasons I ignore, the hfs module does have support for a number of hfsplus features. A corrupt btree header may report variable length keys and trigger this bug, so it's better to fix it.

[ Upstream commit b10298d5 ] fill_with_dentries() failed to propagate errors up to reiserfs_for_each_xattr() properly. Plumb them through. Note that reiserfs_for_each_xattr() is only used by reiserfs_delete_xattrs() and reiserfs_chown_xattrs(). The result of reiserfs_delete_xattrs() is discarded anyway, the only difference there is whether a warning is printed to dmesg. The result of reiserfs_chown_xattrs() does matter because it can block chowning of the file to which the xattrs belong; but either way, the resulting state can have misaligned ownership, so my patch doesn't improve things greatly. Credit for making me look at this code goes to Al Viro, who pointed out that the ->actor calling convention is suboptimal and should be changed.
