[ Upstream commit a5299ce4e96f3e8930e9c051b28d8093ada87b08 ]

ab8500_btemp_external_power_changed() dereferences di->btemp_psy, which gets sets in ab8500_btemp_probe() like this:

        di->btemp_psy = devm_power_supply_register(dev, &ab8500_btemp_desc,
                                                   &psy_cfg);

As soon as devm_power_supply_register() has called device_add() the external_power_changed callback can get called. So there is a window where ab8500_btemp_external_power_changed() may get called while di->btemp_psy has not been set yet leading to a NULL pointer dereference.

Fixing this is easy. The external_power_changed callback gets passed the power_supply which will eventually get stored in di->btemp_psy, so ab8500_btemp_external_power_changed() can simply directly use the passed in psy argument which is always valid.

And the same applies to ab8500_fg_external_power_changed().

From: Marek Vasut <[email protected]>

[ Upstream commit 155c45a25679f571c2ae57d10db843a9dfc63430 ]

Reduce the amount of output this dev_dbg() statement emits into logs, otherwise if system software polls the sysfs entry for data and keeps getting -ENODATA, it could end up filling the logs up.

This does in fact make systemd journald choke, since during boot the sysfs power supply entries are polled and if journald starts at the same time, the journal is just being repeatedly filled up, and the system stops on trying to start journald without booting any further.

From: Mario Limonciello <[email protected]>

[ Upstream commit 95339f40a8b652b5b1773def31e63fc53c26378a ]

The logic used for power_supply_is_system_supplied() counts all power supplies and assumes that the system is running from AC if there is either a non-battery power-supply reporting to be online or if no power-supplies exist at all.

The second rule is for desktop systems, that don't have any battery/charger devices. These systems will incorrectly report to be powered from battery once a device scope power-supply is registered (e.g. a HID device), since these power-supplies increase the counter.

Apart from HID devices, recent dGPUs provide UCSI power supplies on a desktop systems. The dGPU by default doesn't have anything plugged in so it's 'offline'. This makes power_supply_is_system_supplied() return 0 with a count of 1 meaning all drivers that use this get a wrong judgement.

To fix this case adjust the logic to also examine the scope of the power supply. If the power supply is deemed a device power supply, then don't count it.

[ Upstream commit 2d645604f69f3a772d58ead702f9a8e84ab2b342 ]

Various fixes for the Au1200/Au1550/Au1300 DBDMA2 code:

- skip cache invalidation if chip has working coherency circuitry.
- invalidate KSEG0-portion of the (physical) data address.
- force the dma channel doorbell write out to bus immediately with a sync.

[ Upstream commit 4897a898a216058dec55e5e5902534e6e224fcdf ]

PAGE_OFFSET is technically a virtual address so when checking the value of initrd_start against it we should make sure that it has been sanitised from the values passed by the bootloader. Without this change, even with a bootloader that passes correct addresses for an initrd, we are failing to load it on MT7621 boards, for example.

[ Upstream commit b6ebaa8100090092aa602530d7e8316816d0c98d ]

The existing code silently converts read operations with the REQ_FUA bit set into write-barrier operations. This results in data loss as the backend scribbles zeroes over the data instead of returning it.

While the REQ_FUA bit doesn't make sense on a read operation, at least one well-known out-of-tree kernel module does set it and since it results in data loss, let's be safe here and only look at REQ_FUA for writes.

commit 50d927880e0f90d5cb25e897e9d03e5edacc79a8 upstream.

It's trivial to trigger a use-after-free bug in the ocfs2 quotas code using fstest generic/452. After a read-only remount, quotas are suspended and ocfs2_mem_dqinfo is freed through ->ocfs2_local_free_info(). When unmounting the filesystem, an UAF access to the oinfo will eventually cause a crash.

commit 26a6ffff7de5dd369cdb12e38ba11db682f1dec0 upstream.

When changing a file size with fallocate() the new size isn't being checked. In particular, the FSIZE ulimit isn't being checked, which makes fstest generic/228 fail. Simply adding a call to inode_newsize_ok() fixes this issue.

The given value of 1518 seems to refer to the layer 2 ethernet frame size without 802.1Q tag. Actual use of the "max-frame-size" including in the consumer of the "altr,tse-1.0" compatible is the MTU.

commit 2f012f2baca140c488e43d27a374029c1e59098d upstream.

A syzbot fault injection test reported that nilfs_btnode_create_block, a helper function that allocates a new node block for b-trees, causes a kernel BUG for disk images where the file system block size is smaller than the page size.

This was due to unexpected flags on the newly allocated buffer head, and it turned out to be because the buffer flags were not cleared by nilfs_btnode_abort_change_key() after an error occurred during a b-tree update operation and the buffer was later reused in that state.

Fix this issue by using nilfs_btnode_delete() to abandon the unused preallocated buffer in nilfs_btnode_abort_change_key().

commit fee5eaecca86afa544355569b831c1f90f334b85 upstream.

Syzbot reports that in its stress test for resize ioctl, the log writing function nilfs_segctor_do_construct hits a WARN_ON in nilfs_segctor_truncate_segments().

It turned out that there is a problem with the current implementation of the resize ioctl, which changes the writable range on the device (the range of allocatable segments) at the end of the resize process.

This order is necessary for file system expansion to avoid corrupting the superblock at trailing edge. However, in the case of a file system shrink, if log writes occur after truncating out-of-bounds trailing segments and before the resize is complete, segments may be allocated from the truncated space.

The userspace resize tool was fine as it limits the range of allocatable segments before performing the resize, but it can run into this issue if the resize ioctl is called alone.

Fix this issue by changing nilfs_sufile_resize() to update the range of allocatable segments immediately after successful truncation of segment space in case of file system shrink.

commit 1202cdd665315c525b5237e96e0bedc76d7e754f upstream.

DECnet is an obsolete network protocol that receives more attention from kernel janitors than users. It belongs in computer protocol history museum not in Linux kernel.

It has been "Orphaned" in kernel since 2010. The iproute2 support for DECnet was dropped in 5.0 release. The documentation link on Sourceforge says it is abandoned there as well.

Leave the UAPI alone to keep userspace programs compiling. This means that there is still an empty neighbour table for AF_DECNET.

The table of /proc/sys/net entries was updated to match current directories and reformatted to be alphabetical.

commit f1832e2b5e498e258b090af3b065b85cf8cc5161 upstream.

Add support for Quectel EM061KGL series which are based on Qualcomm SDX12 chip:

EM061KGL_LTA(0x2c7c / 0x0123): MBIM + GNSS + DIAG + NMEA + AT + QDSS + DPL EM061KGL_LMS(0x2c7c / 0x0124): MBIM + GNSS + DIAG + NMEA + AT + QDSS + DPL EM061KGL_LWW(0x2c7c / 0x6008): MBIM + GNSS + DIAG + NMEA + AT + QDSS + DPL EM061KGL_LCN(0x2c7c / 0x6009): MBIM + GNSS + DIAG + NMEA + AT + QDSS + DPL

Above products use the exact same interface layout and option driver is for interfaces DIAG, NMEA and AT.

[ Upstream commit 91ffd1bae1dafbb9e34b46813f5b058581d9144d ]

Ping sockets can't send packets when they're bound to a VRF master device and the output interface is set to a slave device.

For example, when net.ipv4.ping_group_range is properly set, so that ping6 can use ping sockets, the following kind of commands fails:

  $ ip vrf exec red ping6 fe80::854:e7ff:fe88:4bf1%eth1

What happens is that sk->sk_bound_dev_if is set to the VRF master device, but 'oif' is set to the real output device. Since both are set but different, ping_v6_sendmsg() sees their value as inconsistent and fails.

Fix this by allowing 'oif' to be a slave device of ->sk_bound_dev_if.

This fixes the following kselftest failure:

  $ ./fcnal-test.sh -t ipv6_ping
  [...]
  TEST: ping out, vrf device+address bind - ns-B IPv6 LLA        [FAIL]

[ Upstream commit 691b0480933f0ce88a81ed1d1a0aff340ff6293a ]

- When a iSER session is released, ib_isert module is taking a mutex lock and releasing all pending connections. As part of this, ib_isert is destroying rdma cm_id. To destroy cm_id, rdma_cm module is sending CM events to CMA handler of ib_isert. This handler is taking same mutex lock. Hence it leads to deadlock between ib_isert & rdma_cm modules.

- For fix, created local list of pending connections and release the connection outside of mutex lock.

When ib_isert module receives connection error event, it is releasing the isert session and removes corresponding list node but it doesn't take appropriate mutex lock to remove the list node. This can lead to linked list corruption

[ Upstream commit 699826f4e30ab76a62c238c86fbef7e826639c8d ]

The ib_isert module is releasing the isert connection both in isert_wait_conn() handler as well as isert_free_conn() handler. In isert_wait_conn() handler, it is expected to wait for iSCSI session logout operation to complete. It should free the isert connection only in isert_free_conn() handler.

When a bunch of iSER target is cleared, this issue can lead to use-after-free memory issue as isert conn is twice released

Add checking for NULL before calling nouveau_connector_detect_depth() in nouveau_connector_get_modes() function because nv_connector->native_mode could be dereferenced there since connector pointer passed to nouveau_connector_detect_depth() and the same value of nv_connector->native_mode is used there.

Previously, timestamps were printed using "%lld.%u" which is incorrect for nanosecond values lower than 100,000,000 as they're fractional digits, therefore leading zeros are meaningful.

This patch changes the format strings to "%lld.%09u" in order to add leading zeros to the nanosecond value.

commit af5cd05de5dd38cf25d14ea4d30ae9b791d2420b upstream.

Our logic for choosing defconfig doesn't work well in some situations.

For example if you're on a ppc64le machine but you specify a non-empty CROSS_COMPILE, in order to use a non-default toolchain, then defconfig will give you ppc64_defconfig (big endian):

  $ make CROSS_COMPILE=~/toolchains/gcc-8/bin/powerpc-linux- defconfig
  *** Default configuration is based on 'ppc64_defconfig'

This is because we assume that CROSS_COMPILE being set means we can't be on a ppc machine and rather than checking we just default to ppc64_defconfig.

We should just ignore CROSS_COMPILE, instead check the machine with uname and if it's one of ppc, ppc64 or ppc64le then use that defconfig. If it's none of those then we fall back to ppc64_defconfig.

commit 003fb0a51162d940f25fc35e70b0996a12c9e08a upstream.

Requests to the mmc layer usually come through a block device IO. The exceptions are the ioctl interface, RPMB chardev ioctl and debugfs, which issue their own blk_mq requests through blk_execute_rq and do not query the BLK_STS error but the mmcblk-internal drv_op_result. This patch ensures that drv_op_result defaults to an error and has to be overwritten by the operation to be considered successful.

The behavior leads to a bug where the request never propagates the error, e.g. by directly erroring out at mmc_blk_mq_issue_rq if mmc_blk_part_switch fails. The ioctl caller of the rpmb chardev then can never see an error (BLK_STS_IOERR, but drv_op_result is unchanged) and thus may assume that their call executed successfully when it did not.

While always checking the blk_execute_rq return value would be advised, let's eliminate the error by always setting drv_op_result as -EIO to be overwritten on success (or other error)
