Michael Chan says: ==================== bnxt_en: Updates for net-next. This series includes the usual firmware spec update. The driver has added external phy loopback test and phy setup retry logic that is needed during hotplug. In the SRIOV space, the driver has added a new VF resource allocation mode that requires the VF driver to reserve resources during IFUP. IF state changes are now propagated to firmware so that firmware can release some resources during IFDOWN. ethtool method to get firmware core dump and hwmon temperature reading have been added. DSCP to user priority support has been added to the driver's DCBNL interface, and the CoS queue logic has been refined to make sure that the special RDMA Congestion Notification hardware CoS queue will not be used for networking traffic. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

The CNP CoS queue is reserved for internal RDMA Congestion Notification Packets (CNP) and should not be used for a TC. Modify the CoS queue discovery code to skip over the CNP CoS queue and to reduce bp->max_tc accordingly. However, if RDMA is disabled in NVRAM, the the CNP CoS queue can be used for a TC.

Expand the .ieee_setapp() and ieee_delapp() DCBNL methods to support DSCP. This allows DSCP values to user priority mappings instead of using VLAN priorities. Each DSCP mapping is added or deleted one entry at a time using the firmware API. The firmware call can only be made from a PF.

Set the default hash mode flag in HWRM_VNIC_RSS_CFG to signal to the firmware that the driver is compliant with the latest spec. With that, the firmware can return expanded RSS profile IDs that the driver checks to setup the proper gso_type for GRO-HW packets. But instead of checking for the new profile IDs, we check the IP_TYPE flag in TPA_START which is more straight forward than checking a list of profile IDs.

During hotplug, the driver's open function can be called almost immediately after power on reset.

The driver gathers statistics using 2 mechanisms. Some stats are DMA'ed directly from hardware and others are polled from the driver's timer. Currently, we only adjust the DMA frequency based on the ethtool stats-block-usecs setting. This patch adjusts the driver's timer frequency as well to make everything consistent.

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for your net-next tree: 1) Support for transparent proxying for nf_tables, from Mate Eckl. 2) Patchset to add OS passive fingerprint recognition for nf_tables, from Fernando Fernandez. This takes common code from xt_osf and place it into the new nfnetlink_osf module for codebase sharing. 3) Lightweight tunneling support for nf_tables. 4) meta and lookup are likely going to be used in rulesets, make them direct calls. From Florian Westphal. A bunch of incremental updates: 5) use PTR_ERR_OR_ZERO() from nft_numgen, from YueHaibing. 6) Use kvmalloc_array() to allocate hashtables, from Li RongQing. 7) Explicit dependencies between nfnetlink_cttimeout and conntrack timeout extensions, from Harsha Sharma. 8) Simplify NLM_F_CREATE handling in nf_tables. 9) Removed unused variable in the get element command, from YueHaibing. 10) Expose bridge hook priorities through uapi, from Mate Eckl. And a few fixes for previous Netfilter batch for net-next: 11) Use per-netns mutex from flowtable event, from Florian Westphal. 12) Remove explicit dependency on iptables CT target from conntrack zones, from Florian. 13) Fix use-after-free in rmmod nf_conntrack path, also from Florian. ==================== Signed-off-by: David S.

It turns out that commit 721c7fc7 ("block: fail op_is_write() requests to read-only partitions"), while obviously correct, causes problems for some older lvm2 installations. The reason is that the lvm snapshotting will continue to write to the snapshow COW volume, even after the volume has been marked read-only. End result: snapshot failure. This has actually been fixed in newer version of the lvm2 tool, but the old tools still exist, and the breakage was reported both in the kernel bugzilla and in the Debian bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=200439 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900442 The lvm2 fix is here https://sourceware.org/git/?p=lvm2.git;a=commit;h=a6fdb9d9d70f51c49ad11a87ab4243344e6701a3 but until everybody has updated to recent versions, we'll have to weaken the "never write to read-only partitions" check. It now allows the write to happen, but causes a warning, something like this: generic_make_request: Trying to write to read-only block-device dm-3 (partno X) Modules linked in: nf_tables xt_cgroup xt_owner kvm_intel iwlmvm kvm irqbypass iwlwifi CPU: 1 PID: 77 Comm: kworker/1:1 Not tainted 4.17.9-gentoo #3 Hardware name: LENOVO 20B6A019RT/20B6A019RT, BIOS GJET91WW (2.41 ) 09/21/2016 Workqueue: ksnaphd do_metadata RIP: 0010:generic_make_request_checks+0x4ac/0x600 ...

I'm leaving alone the actual code cleanups in commit 721c7fc7, but letting the previously uncaught request go through with a warning instead of stopping it.

It's legal to have 64 groups for netlink_sock. As user-supplied nladdr->nl_groups is __u32, it's possible to subscribe only to first 32 groups. The check for correctness of .bind() userspace supplied parameter is done by applying mask made from ngroups shift. Which broke Android as they have 64 groups and the shift for mask resulted in an overflow. Fixes: 61f4b237 ("netlink: Don't shift with UB on nlk->ngroups") Cc: "David S.

Bart Massey reported what turned out to be a usercopy whitelist false positive in JFS when symlink contents exceeded 128 bytes. The inline inode data (i_inline) is actually designed to overflow into the "extended area" following it (i_inline_ea) when needed. So the whitelist needed to be expanded to include both i_inline and i_inline_ea (the whole size of which is calculated internally using IDATASIZE, 256, instead of sizeof(i_inline), 128). $ cd /mnt/jfs $ touch $(perl -e 'print "B" x 250') $ ln -s B* b $ ls -l >/dev/null [ 249.436410] Bad or missing usercopy whitelist?

Applications use -ECONNREFUSED as returned from write() in order to determine that a socket should be closed. However, when using connected dgram unix sockets in a poll/write loop, a final POLLOUT event can be missed when the remote end closes. Thus, the poll is stuck forever: thread 1 (client) thread 2 (server) connect() to server write() returns -EAGAIN unix_dgram_poll() -> unix_recvq_full() is true close() ->unix_release_sock() ->wake_up_interruptible_all() unix_dgram_poll() (due to the wake_up_interruptible_all) -> unix_recvq_full() still is true ->free all skbs Now thread 1 is stuck and will not receive anymore wakeups. In this case, when thread 1 gets the -EAGAIN, it has not queued any skbs otherwise the 'free all skbs' step would in fact cause a wakeup and a POLLOUT return. So the race here is probably fairly rare because it means there are no skbs that thread 1 queued and that thread 1 schedules before the 'free all skbs' step. This issue was reported as a hang when /dev/log is closed. The fix is to signal POLLOUT if the socket is marked as SOCK_DEAD, which means a subsequent write() will get -ECONNREFUSED.
