Currently when TC num is one, the DCB will be disabled no matter if pfc_en is non-zero or not. This patch enables the DCB if pfc_en is non-zero, even when TC num is one.

When change MTU or other operations, which just calling .reset_notify to do HNAE3_DOWN_CLIENT and HNAE3_UP_CLIENT, then the netdev_tx_reset_queue() in the hns3_clear_all_ring() will be ignored. So the dev_watchdog() may misdiagnose a TX timeout. This patch separates netdev_tx_reset_queue() from hns3_clear_all_ring(), and unifies hns3_clear_all_ring() and hns3_force_clear_all_ring into one, since they are doing similar things.

Vladimir Oltean says: ==================== Better PHYLINK compliance for SJA1105 DSA After discussing with Russell King, it appears this driver is making a few confusions and not performing some checks for consistent operation.

We need a better way to signal this, perhaps in phylink_validate, but for now just print this error message as guidance for other people looking at this driver's code while trying to rework PHYLINK.

PHYLINK being designed with PHYs in mind that can change MII protocol, for correct operation it is necessary to ensure that the PHY interface mode stays the same (otherwise clear the supported bit mask, as required). Because this is just a hypothetical situation for now, we don't bother to check whether we could actually support the new PHY interface mode. Actually we could modify the xMII table, reset the switch and send an updated static configuration, but adding that would just be dead code.

It has been pointed out that PHYLINK can call mac_config only to update the phy_interface_type and without knowing what the AN results are. Experimentally, when this was observed to happen, state->link was also unset, and therefore was used as a proxy to ignore this call. However it is also suggested that state->link is undefined for this callback and should not be relied upon. So let the previously-dead codepath for SPEED_UNKNOWN be called, and update the comment to make sure the MAC's behavior is sane.

On 32-bit architectures, putting an array of 256 u32 values on the stack uses more space than the warning limit: drivers/net/ethernet/huawei/hinic/hinic_main.c: In function 'hinic_rss_init': drivers/net/ethernet/huawei/hinic/hinic_main.c:286:1: error: the frame size of 1068 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] I considered changing the code to use u8 values here, since that's all the hardware supports, but dynamically allocating the array is a more isolated fix here.

Pull pidfd fixes from Christian Brauner: "Userspace tools and libraries such as strace or glibc need a cheap and reliable way to tell whether CLONE_PIDFD is supported. The easiest way is to pass an invalid fd value in the return argument, perform the syscall and verify the value in the return argument has been changed to a valid fd. However, if CLONE_PIDFD is specified we currently check if pidfd == 0 and return EINVAL if not. The check for pidfd == 0 was originally added to enable us to abuse the return argument for passing additional flags along with CLONE_PIDFD in the future. However, extending legacy clone this way would be a terrible idea and with clone3 on the horizon and the ability to reuse CLONE_DETACHED with CLONE_PIDFD there's no real need for this clutch. So remove the pidfd == 0 check and help userspace out. Also, accordig to Al, anon_inode_getfd() should only be used past the point of no failure and ksys_close() should not be used at all since it is far too easy to get wrong. Al's motto being "basically, once it's in descriptor table, it's out of your control". So Al's patch switches back to what we already had in v1 of the original patchset and uses a anon_inode_getfile() + put_user() + fd_install() sequence in the success path and a fput() + put_unused_fd() in the failure path. The other two changes should be trivial" * tag 'for-linus-20190627' of gitolite.kernel.org:pub/scm/linux/kernel/git/brauner/linux: proc: remove useless d_is_dir() check copy_process(): don't use ksys_close() on cleanups samples: make pidfd-metadata fail gracefully on older kernels fork: don't check parent_tidptr with CLONE_PIDFD

Pull AFS fixes from David Howells: "The in-kernel AFS client has been undergoing testing on opendev.org on one of their mirror machines. They are using AFS to hold data that is then served via apache, and Ian Wienand had reported seeing oopses, spontaneous machine reboots and updates to volumes going missing. This patch series appears to have fixed the problem, very probably due to patch (2), but it's not 100% certain. (1) Fix the printing of the "vnode modified" warning to exclude checks on files for which we don't have a callback promise from the server (and so don't expect the server to tell us when it changes). Without this, for every file or directory for which we still have an in-core inode that gets changed on the server, we may get a message logged when we next look at it. This can happen in bulk if, for instance, someone does "vos release" to update a R/O volume from a R/W volume and a whole set of files are all changed together. We only really want to log a message if the file changed and the server didn't tell us about it or we failed to track the state internally. (2) Fix accidental corruption of either afs_vlserver struct objects or the the following memory locations (which could hold anything). The issue is caused by a union that points to two different structs in struct afs_call (to save space in the struct). The call cleanup code assumes that it can simply call the cleanup for one of those structs if not NULL - when it might be actually pointing to the other struct. This means that every Volume Location RPC op is going to corrupt something. (3) Fix an uninitialised spinlock. This isn't too bad, it just causes a one-off warning if lockdep is enabled when "vos release" is called, but the spinlock still behaves correctly. (4) Fix the setting of i_block in the inode. This causes du, for example, to produce incorrect results, but otherwise should not be dangerous to the kernel" * tag 'afs-fixes-20190620' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: afs: Fix setting of i_blocks afs: Fix uninitialised spinlock afs_volume::cb_break_lock afs: Fix vlserver record corruption afs: Fix over zealous "vnode modified" warnings
