commit 973c096f upstream. Yunhai Zhang recently fixed a VGA software scrollback bug in commit ebfdfeea ("vgacon: Fix for missing check in scrollback handling"), but that then made people look more closely at some of this code, and there were more problems on the vgacon side, but also the fbcon software scrollback. We don't really have anybody who maintains this code - probably because nobody actually _uses_ it any more. Sure, people still use both VGA and the framebuffer consoles, but they are no longer the main user interfaces to the kernel, and haven't been for decades, so these kinds of extra features end up bitrotting and not really being used. So rather than try to maintain a likely unused set of code, I'll just aggressively remove it, and see if anybody even notices. Maybe there are people who haven't jumped on the whole GUI badnwagon yet, and think it's just a fad. And maybe those people use the scrollback code. If that turns out to be the case, we can resurrect this again, once we've found the sucker^Wmaintainer for it who actually uses it. Reported-by:

commit 50145474 upstream. This (and the VGA soft scrollback) turns out to have various nasty small special cases that nobody really is willing to fight. The soft scrollback code was really useful a few decades ago when you typically used the console interactively as the main way to interact with the machine, but that just isn't the case any more. So it's not worth dragging along. Tested-by:

commit f44d04e6 upstream. It turns out that currently we rely only on sysfs attribute permissions: $ ll /sys/bus/rbd/{add*,remove*} --w------- 1 root root 4096 Sep 3 20:37 /sys/bus/rbd/add --w------- 1 root root 4096 Sep 3 20:37 /sys/bus/rbd/add_single_major --w------- 1 root root 4096 Sep 3 20:37 /sys/bus/rbd/remove --w------- 1 root root 4096 Sep 3 20:38 /sys/bus/rbd/remove_single_major This means that images can be mapped and unmapped (i.e. block devices can be created and deleted) by a UID 0 process even after it drops all privileges or by any process with CAP_DAC_OVERRIDE in its user namespace as long as UID 0 is mapped into that user namespace. Be consistent with other virtual block devices (loop, nbd, dm, md, etc) and require CAP_SYS_ADMIN in the initial user namespace for mapping and unmapping, and also for dumping the configuration string and refreshing the image header.

commit ed43ffea upstream. The iSCSI target login thread might get stuck with the following stack: cat /proc/`pidof iscsi_np`/stack [<0>] down_interruptible+0x42/0x50 [<0>] iscsit_access_np+0xe3/0x167 [<0>] iscsi_target_locate_portal+0x695/0x8ac [<0>] __iscsi_target_login_thread+0x855/0xb82 [<0>] iscsi_target_login_thread+0x2f/0x5a [<0>] kthread+0xfa/0x130 [<0>] ret_from_fork+0x1f/0x30 This can be reproduced via the following steps: 1. Initiator A tries to log in to iqn1-tpg1 on port 3260. After finishing PDU exchange in the login thread and before the negotiation is finished the the network link goes down. At this point A has not finished login and tpg->np_login_sem is held. 2. Initiator B tries to log in to iqn2-tpg1 on port 3260. After finishing PDU exchange in the login thread the target expects to process remaining login PDUs in workqueue context. 3. Initiator A' tries to log in to iqn1-tpg1 on port 3260 from a new socket. A' will wait for tpg->np_login_sem with np->np_login_timer loaded to wait for at most 15 seconds. The lock is held by A so A' eventually times out. 4. Before A' got timeout initiator B gets negotiation failed and calls iscsi_target_login_drop()->iscsi_target_login_sess_out(). The np->np_login_timer is canceled and initiator A' will hang forever. Because A' is now in the login thread, no new login requests can be serviced. Fix this by moving iscsi_stop_login_thread_timer() out of iscsi_target_login_sess_out(). Also remove iscsi_np parameter from iscsi_target_login_sess_out(). Link: https://lore.kernel.org/r/20200729130343.24976-1-houpu@bytedance.com Cc: stable@vger.kernel.org Reviewed-by:

commit 1c78544e upstream. When faulting in the pages for the user supplied buffer for the search ioctl, we are passing only the base address of the buffer to the function fault_in_pages_writeable(). This means that after the first iteration of the while loop that searches for leaves, when we have a non-zero offset, stored in 'sk_offset', we try to fault in a wrong page range. So fix this by adding the offset in 'sk_offset' to the base address of the user supplied buffer when calling fault_in_pages_writeable(). Several users have reported that the applications compsize and bees have started to operate incorrectly since commit a48b73ec ("btrfs: fix potential deadlock in the search ioctl") was added to stable trees, and these applications make heavy use of the search ioctls. This fixes their issues.

commit 66a35939 upstream. Many USB drivers iterate over the available endpoints to find required endpoints of a specific type and direction. Typically the endpoints are required for proper function and a missing endpoint should abort probe. To facilitate code reuse, add a helper to retrieve common endpoints (bulk or interrupt, in or out) and four wrappers to find a single endpoint. Note that the helpers are marked as __must_check to serve as a reminder to always verify that all expected endpoints are indeed present. This also means that any optional endpoints, typically need to be looked up through separate calls. Signed-off-by:

commit 89226a29 upstream. One of a class of bugs pointed out by Lars in a recent review. iio_push_to_buffers_with_timestamp assumes the buffer used is aligned to the size of the timestamp (8 bytes). This is not guaranteed in this driver which uses a 16 byte u8 array on the stack. As Lars also noted this anti pattern can involve a leak of data to userspace and that indeed can happen here. We close both issues by moving to a suitable structure in the iio_priv() data with alignment ensured by use of an explicit c structure. This data is allocated with kzalloc so no data can leak appart from previous readings. The additional forcing of the 8 byte alignment of the timestamp is not strictly necessary but makes the code less fragile by making this explicit.

[ Upstream commit 13774d81 ] In snd_hdac_device_init pm_runtime_set_active is called to increase child_count in parent device. But when it is failed to build connection with GPU for one case that integrated graphic gpu is disabled, snd_hdac_ext_bus_device_exit will be invoked to clean up a HD-audio extended codec base device. At this time the child_count of parent is not decreased, which makes parent device can't get suspended. This patch calls pm_runtime_set_suspended to decrease child_count in parent device in snd_hdac_device_exit to match with snd_hdac_device_init. pm_runtime_set_suspended can make sure that it will not decrease child_count if the device is already suspended.

[ Upstream commit 91244d10 ] Set the skb's network_header before it is passed to the underlying Ethernet device for transmission. This patch fixes the following issue: When we use this driver with AF_PACKET sockets, there would be error messages of: protocol 0805 is buggy, dev (Ethernet interface name) printed in the system "dmesg" log. This is because skbs passed down to the Ethernet device for transmission don't have their network_header properly set, and the dev_queue_xmit_nit function in net/core/dev.c complains about this. Reason of setting the network_header to this place (at the end of the Ethernet header, and at the beginning of the Ethernet payload): Because when this driver receives an skb from the Ethernet device, the network_header is also set at this place.

[ Upstream commit 53de092f ] It was discovered that sdparm will fail when attempting to disable write cache on a SATA disk connected via libsas. In the ATA command set the write cache state is controlled through the SET FEATURES operation. This is roughly corresponds to MODE SELECT in SCSI and the latter command is what is used in the SCSI-ATA translation layer. A subtle difference is that a MODE SELECT carries data whereas SET FEATURES is defined as a non-data command in ATA. Set the DMA data direction to DMA_NONE if the requested ATA command is identified as non-data.
