commit 003fb0a5 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) Fixes: 614f0388 ("mmc: block: move single ioctl() commands to block requests") Signed-off-by:

commit af5cd05d 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.

[ Upstream commit 691b0480 ] - 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.

[ Upstream commit 91ffd1ba ] 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] Reported-by:

commit 1202cdd6 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. Signed-off-by:

commit fee5eaec 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 2f012f2b 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().

[ Upstream commit b6ebaa81 ] 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.

[ Upstream commit 95339f40 ] 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 a5299ce4 ] 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(). Signed-off-by:

commit 85f02d6c upstream. In btrfs_relocate_block_group(), the rc is allocated. Then btrfs_relocate_block_group() calls relocate_block_group() prepare_to_relocate() set_reloc_control() that assigns rc to the variable fs_info->reloc_ctl. When prepare_to_relocate() returns, it calls btrfs_commit_transaction() btrfs_start_dirty_block_groups() btrfs_alloc_path() kmem_cache_zalloc() which may fail for example (or other errors could happen). When the failure occurs, btrfs_relocate_block_group() detects the error and frees rc and doesn't set fs_info->reloc_ctl to NULL. After that, in btrfs_init_reloc_root(), rc is retrieved from fs_info->reloc_ctl and then used, which may cause a use-after-free bug. This possible bug can be triggered by calling btrfs_ioctl_balance() before calling btrfs_ioctl_defrag(). To fix this possible bug, in prepare_to_relocate(), check if btrfs_commit_transaction() fails. If the failure occurs, unset_reloc_control() is called to set fs_info->reloc_ctl to NULL. The error log in our fault-injection testing is shown as follows: [ 58.751070] BUG: KASAN: use-after-free in btrfs_init_reloc_root+0x7ca/0x920 [btrfs] ... [ 58.753577] Call Trace: ...
