commit 7e78c59 upstream. This check was incomplete, did not consider size is 0: if (len != ALIGN(size, 4) + hdrlen) goto err; if size from qrtr_hdr is 0, the result of ALIGN(size, 4) will be 0, In case of len == hdrlen and size == 0 in header this check won't fail and if (cb->type == QRTR_TYPE_NEW_SERVER) { /* Remote node endpoint can bridge other distant nodes */ const struct qrtr_ctrl_pkt *pkt = data + hdrlen; qrtr_node_assign(node, le32_to_cpu(pkt->server.node)); } will also read out of bound from data, which is hdrlen allocated block.

[ Upstream commit 4608fdf ] Michal Kubecek reports that conntrack gc is responsible for frequent wakeups (every 125ms) on idle systems. On busy systems, timed out entries are evicted during lookup. The gc worker is only needed to remove entries after system becomes idle after a busy period. To resolve this, always scan the entire table. If the scan is taking too long, reschedule so other work_structs can run and resume from next bucket. After a completed scan, wait for 2 minutes before the next cycle. Heuristics for faster re-schedule are removed. GC_SCAN_INTERVAL could be exposed as a sysctl in the future to allow tuning this as-needed or even turn the gc worker off.

[ Upstream commit 9066e5c ] Recently we found an issue on our production environment that when memcg oom is triggered the oom killer doesn't chose the process with largest resident memory but chose the first scanned process. Note that all processes in this memcg have the same oom_score_adj, so the oom killer should chose the process with largest resident memory. Bellow is part of the oom info, which is enough to analyze this issue.

That is because, when we calculate the oom badness in oom_badness(), we always ignore the negtive point and convert all of these negtive points to 1. Now as oom_score_adj of all the processes in this targeted memcg have the same value -998, the points of these processes are all negtive value. As a result, the first scanned process will be killed. The oom_socre_adj (-998) in this memcg is set by kubelet, because it is a a Guaranteed pod, which has higher priority to prevent from being killed by system oom. To fix this issue, we should make the calculation of oom point more accurate. We can achieve it by convert the chosen_point from 'unsigned long' to 'long'.

commit df7b16d upstream. This reverts commit 3c18e9b. These devices do not appear to send a zero-length packet when the transfer size is a multiple of the bulk-endpoint max-packet size.

commit 51f1954 upstream. We can't depend on the TRB's HWO bit to determine if the TRB ring is "full". A TRB is only available when the driver had processed it, not when the controller consumed and relinquished the TRB's ownership to the driver. Otherwise, the driver may overwrite unprocessed TRBs.

commit 4a1e25c upstream. During a USB cable disconnect, or soft disconnect scenario, a pending SETUP transaction may not be completed, leading to the following error: dwc3 a600000.dwc3: timed out waiting for SETUP phase If this occurs, then the entire pullup disable routine is skipped and proper cleanup and halting of the controller does not complete. Instead of returning an error (which is ignored from the UDC perspective), allow the pullup disable routine to continue, which will also handle disabling of EP0/1. This will end any active transfers as well. Ensure to clear any delayed_status also, as the timeout could happen within the STATUS stage.

Fix it so that userspace gets more appropriate EEXIST instead what makes debugging much easier. Before: # ./ifname.sh + ip netns add ns0 + ip netns exec ns0 ip link add l0 type dummy + ip netns exec ns0 ip link show l0 8: l0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 66:90:b5:d5:78:69 brd ff:ff:ff:ff:ff:ff + ip link add l0 type dummy + ip link show l0 10: l0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 6e:c6:1f:15:20:8d brd ff:ff:ff:ff:ff:ff + ip link set l0 netns ns0 RTNETLINK answers: Invalid argument After: # ./ifname.sh + ip netns add ns0 + ip netns exec ns0 ip link add l0 type dummy + ip netns exec ns0 ip link show l0 8: l0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 1e:4a:72:e3:e3:8f brd ff:ff:ff:ff:ff:ff + ip link add l0 type dummy + ip link show l0 10: l0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether f2:fc:fe:2b:7d:a6 brd ff:ff:ff:ff:ff:ff + ip link set l0 netns ns0 RTNETLINK answers: File exists The problem is that do_setlink() passes its `char *ifname` argument, that it gets from a caller, to __dev_change_net_namespace() as is (as `const char *pat`), but semantics of ifname and pat can be different. For example, __rtnl_newlink() does this: net/core/rtnetlink.c 3270 char ifname[IFNAMSIZ]; ... 3286 if (tb[IFLA_IFNAME]) 3287 nla_strscpy(ifname, tb[IFLA_IFNAME], IFNAMSIZ); 3288 else 3289 ifname[0] = '\0'; ... 3364 if (dev) { ... 3394 return do_setlink(skb, dev, ifm, extack, tb, ifname, status); 3395 } , i.e. do_setlink() gets ifname pointer that is always valid no matter if user specified IFLA_IFNAME or not and then do_setlink() passes this ifname pointer as is to __dev_change_net_namespace() as pat argument. But the pat (pattern) in __dev_change_net_namespace() is used as: net/core/dev.c 11198 err = -EEXIST; 11199 if (__dev_get_by_name(net, dev->name)) { 11200 /* We get here if we can't use the current device name */ 11201 if (!pat) 11202 goto out; 11203 err = dev_get_valid_name(net, dev, pat); 11204 if (err < 0) 11205 goto out; 11206 } As the result the `goto out` path on line 11202 is neven taken and instead of returning EEXIST defined on line 11198, __dev_change_net_namespace() returns an error from dev_get_valid_name() and this, in turn, will be EINVAL for ifname[0] = '\0' set earlier.

[ Upstream commit e74cfa9 ] As __vringh_iov() traverses a descriptor chain, it populates each descriptor entry into either read or write vring iov and increments that iov's ->used member. So, as we iterate over a descriptor chain, at any point, (riov/wriov)->used value gives the number of descriptor enteries available, which are to be read or written by the device. As all read iovs must precede the write iovs, wiov->used should be zero when we are traversing a read descriptor. Current code checks for wiov->i, to figure out whether any previous entry in the current descriptor chain was a write descriptor. However, iov->i is only incremented, when these vring iovs are consumed, at a later point, and remain 0 in __vringh_iov(). So, correct the check for read and write descriptor order, to use wiov->used.

[ Upstream commit fa0b1ef ] [Why] Userspace should get back a copy of drm_wait_vblank that's been modified even when drm_wait_vblank_ioctl returns a failure. Rationale: drm_wait_vblank_ioctl modifies the request and expects the user to read it back. When the type is RELATIVE, it modifies it to ABSOLUTE and updates the sequence to become current_vblank_count + sequence (which was RELATIVE), but now it became ABSOLUTE. drmWaitVBlank (in libdrm) expects this to be the case as it modifies the request to be Absolute so it expects the sequence to would have been updated. The change is in compat_drm_wait_vblank, which is called by drm_compat_ioctl. This change of copying the data back regardless of the return number makes it en par with drm_ioctl, which always copies the data before returning.

This old RDS bug was exposed and reliably causes kernel panics (using RDMA operations "rds-stress -D") on x86_64 starting with: commit c588072 ("iommu/vt-d: Convert intel iommu driver to the iommu ops") Simply put: Linux 5.11 and later.

commit bc0939f upstream. We have a race between marking that an inode needs to be logged, either at btrfs_set_inode_last_trans() or at btrfs_page_mkwrite(), and between btrfs_sync_log(). The following steps describe how the race happens. 1) We are at transaction N; 2) Inode I was previously fsynced in the current transaction so it has: inode->logged_trans set to N; 3) The inode's root currently has: root->log_transid set to 1 root->last_log_commit set to 0 Which means only one log transaction was committed to far, log transaction 0. When a log tree is created we set ->log_transid and ->last_log_commit of its parent root to 0 (at btrfs_add_log_tree()); 4) One more range of pages is dirtied in inode I; 5) Some task A starts an fsync against some other inode J (same root), and so it joins log transaction 1. Before task A calls btrfs_sync_log()... 6) Task B starts an fsync against inode I, which currently has the full sync flag set, so it starts delalloc and waits for the ordered extent to complete before calling btrfs_inode_in_log() at btrfs_sync_file(); 7) During ordered extent completion we have btrfs_update_inode() called against inode I, which in turn calls btrfs_set_inode_last_trans(), which does the following: spin_lock(&inode->lock); inode->last_trans = trans->transaction->transid; inode->last_sub_trans = inode->root->log_transid; inode->last_log_commit = inode->root->last_log_commit; spin_unlock(&inode->lock); So ->last_trans is set to N and ->last_sub_trans set to 1. But before setting ->last_log_commit... 8) Task A is at btrfs_sync_log(): - it increments root->log_transid to 2 - starts writeback for all log tree extent buffers - waits for the writeback to complete - writes the super blocks - updates root->last_log_commit to 1 It's a lot of slow steps between updating root->log_transid and root->last_log_commit; 9) The task doing the ordered extent completion, currently at btrfs_set_inode_last_trans(), then finally runs: inode->last_log_commit = inode->root->last_log_commit; spin_unlock(&inode->lock); Which results in inode->last_log_commit being set to 1. The ordered extent completes; 10) Task B is resumed, and it calls btrfs_inode_in_log() which returns true because we have all the following conditions met: inode->logged_trans == N which matches fs_info->generation && inode->last_subtrans (1) <= inode->last_log_commit (1) && inode->last_subtrans (1) <= root->last_log_commit (1) && list inode->extent_tree.modified_extents is empty And as a consequence we return without logging the inode, so the existing logged version of the inode does not point to the extent that was written after the previous fsync. It should be impossible in practice for one task be able to do so much progress in btrfs_sync_log() while another task is at btrfs_set_inode_last_trans() right after it reads root->log_transid and before it reads root->last_log_commit. Even if kernel preemption is enabled we know the task at btrfs_set_inode_last_trans() can not be preempted because it is holding the inode's spinlock. However there is another place where we do the same without holding the spinlock, which is in the memory mapped write path at: vm_fault_t btrfs_page_mkwrite(struct vm_fault *vmf) { (...) BTRFS_I(inode)->last_trans = fs_info->generation; BTRFS_I(inode)->last_sub_trans = BTRFS_I(inode)->root->log_transid; BTRFS_I(inode)->last_log_commit = BTRFS_I(inode)->root->last_log_commit; (...) So with preemption happening after setting ->last_sub_trans and before setting ->last_log_commit, it is less of a stretch to have another task do enough progress at btrfs_sync_log() such that the task doing the memory mapped write ends up with ->last_sub_trans and ->last_log_commit set to the same value. It is still a big stretch to get there, as the task doing btrfs_sync_log() has to start writeback, wait for its completion and write the super blocks. So fix this in two different ways: 1) For btrfs_set_inode_last_trans(), simply set ->last_log_commit to the value of ->last_sub_trans minus 1; 2) For btrfs_page_mkwrite() only set the inode's ->last_sub_trans, just like we do for buffered and direct writes at btrfs_file_write_iter(), which is all we need to make sure multiple writes and fsyncs to an inode in the same transaction never result in an fsync missing that the inode changed and needs to be logged. Turn this into a helper function and use it both at btrfs_page_mkwrite() and at btrfs_file_write_iter() - this also fixes the problem that at btrfs_page_mkwrite() we were setting those fields without the protection of the inode's spinlock. This is an extremely unlikely race to happen in practice.

commit 112022b upstream Mark NX as being used for all non-nested shadow MMUs, as KVM will set the NX bit for huge SPTEs if the iTLB mutli-hit mitigation is enabled. Checking the mitigation itself is not sufficient as it can be toggled on at any time and KVM doesn't reset MMU contexts when that happens. KVM could reset the contexts, but that would require purging all SPTEs in all MMUs, for no real benefit. And, KVM already forces EFER.NX=1 when TDP is disabled (for WP=0, SMEP=1, NX=0), so technically NX is never reserved for shadow MMUs.

commit c7e9d00 upstream. The patch breaks userspace implementations (e.g. fdutils) and introduces regressions in behaviour. Previously, it was possible to O_NDELAY open a floppy device with no media inserted or with write protected media without an error. Some userspace tools use this particular behavior for probing. It's not the first time when we revert this patch. Previous revert is in commit f2791e7 (Revert "floppy: refactor open() flags handling"). This reverts commit 8a0c014.

…octls commit d0efb16 upstream. A common implementation of isatty(3) involves calling a ioctl passing a dummy struct argument and checking whether the syscall failed -- bionic and glibc use TCGETS (passing a struct termios), and musl uses TIOCGWINSZ (passing a struct winsize). If the FD is a socket, we will copy sizeof(struct ifreq) bytes of data from the argument and return -EFAULT if that fails. The result is that the isatty implementations may return a non-POSIX-compliant value in errno in the case where part of the dummy struct argument is inaccessible, as both struct termios and struct winsize are smaller than struct ifreq (at least on arm64). Although there is usually enough stack space following the argument on the stack that this did not present a practical problem up to now, with MTE stack instrumentation it's more likely for the copy to fail, as the memory following the struct may have a different tag. Fix the problem by adding an early check for whether the ioctl is a valid socket ioctl, and return -ENOTTY if it isn't.
