The following commands will cause a memory leak: # cd /sys/kernel/tracing # mkdir instances/foo # echo schedule > instance/foo/set_ftrace_filter # rmdir instances/foo The reason is that the hashes that hold the filters to set_ftrace_filter and set_ftrace_notrace are not freed if they contain any data on the instance and the instance is removed.

When create_event_filter() fails in set_trigger_filter(), the filter may still be allocated and needs to be freed. The caller expects the data->filter to be updated with the new filter, even if the new filter failed (we could add an error message by setting set_str parameter of create_event_filter(), but that's another update). But because the error would just exit, filter was left hanging and nothing could free it. Found by kmemleak detector.

The create_filter() calls create_filter_start() which allocates a "parse_error" descriptor, but fails to call create_filter_finish() that frees it. The op_stack and inverts in predicate_parse() were also not freed. Found by kmemleak detector.

Commit '88ba95be ("backlight: pwm_bl: Compute brightness of LED linearly to human eye")' allows the possibility to compute a default brightness table when there isn't the brightness-levels property in the DT. Unfortunately the changes made broke the pwm backlight for the non-DT boards. Usually, the non-DT boards don't pass the brightness levels via platform data, instead, it sets the max_brightness in their platform data and the driver calculates the level without a table. The offending patch assumed that when there is no brightness levels table we should create one, but this is clearly wrong for the non-DT case. After this patch the code handles the DT and the non-DT case taking in consideration also if max_brightness is set or not.

The CP rings are accounted differently on the new 57500 chips. There must be enough CP rings for the sum of RX and TX rings on the new chips. The current logic may be over-estimating the RX and TX rings. The output parameter max_cp should be the maximum NQs capped by MSIX vectors available for networking in the context of 57500 chips. The existing code which uses CMPL rings capped by the MSIX vectors works most of the time but is not always correct. Signed-off-by: NMichael Chan <michael.chan@broadcom.com> Signed-off-by: NDavid S.

The new 57500 chips have introduced the NQ structure in addition to the existing CP rings in all chips. We need to introduce a new bnxt_nq_rings_in_use(). On legacy chips, the 2 functions are the same and one will just call the other. On the new chips, they refer to the 2 separate ring structures. The new function is now called to determine the resource (NQ or CP rings) associated with MSIX that are in use. On 57500 chips, the RDMA driver does not use the CP rings so we don't need to do the subtraction adjustment. Fixes: 41e8d798 ("bnxt_en: Modify the ring reservation functions for 57500 series chips.")

Recent changes to support the 57500 devices have created this regression. The bnxt_hwrm_queue_qportcfg() call was moved to be called earlier before the RDMA support was determined, causing the CoS queues configuration to be set before knowing whether RDMA was supported or not.

This reverts commit 89c83fb5. This should have been done as part of 2f0799a0 ("mm, thp: restore node-local hugepage allocations"). The movement of the thp allocation policy from alloc_pages_vma() to alloc_hugepage_direct_gfpmask() was intended to only set __GFP_THISNODE for mempolicies that are not MPOL_BIND whereas the revert could set this regardless of mempolicy. While the check for MPOL_BIND between alloc_hugepage_direct_gfpmask() and alloc_pages_vma() was racy, that has since been removed since the revert. What is left is the possibility to use __GFP_THISNODE in policy_node() when it is unexpected because the special handling for hugepages in alloc_pages_vma() was removed as part of the consolidation. Secondly, prior to 89c83fb5, alloc_pages_vma() implemented a somewhat different policy for hugepage allocations, which were allocated through alloc_hugepage_vma(). For hugepage allocations, if the allocating process's node is in the set of allowed nodes, allocate with __GFP_THISNODE for that node (for MPOL_PREFERRED, use that node with __GFP_THISNODE instead). This was changed for shmem_alloc_hugepage() to allow fallback to other nodes in 89c83fb5 as it did for new_page() in mm/mempolicy.c which is functionally different behavior and removes the requirement to only allocate hugepages locally. So this commit does a full revert of 89c83fb5 instead of the partial revert that was done in 2f0799a0. The result is the same thp allocation policy for 4.20 that was in 4.19.

This reverts commit 624ca9c3. This commit is completely bogus. The STACR register has two formats, old and new, depending on the version of the IP block used. There's a pair of device-tree properties that can be used to specify the format used: has-inverted-stacr-oc has-new-stacr-staopc What this commit did was to change the bit definition used with the old parts to match the new parts. This of course breaks the driver on all the old ones. Instead, the author should have set the appropriate properties in the device-tree for the variant used on his board.

Stefano Brivio says: ==================== Fix slab out-of-bounds on insufficient headroom for IPv6 packets Patch 1/2 fixes a slab out-of-bounds occurring with short SCTP packets over IPv4 over L2TP over IPv6 on a configuration with relatively low HEADER_MAX. Patch 2/2 makes sure we avoid writing before the allocated buffer in neigh_hh_output() in case the headroom is enough for the unaligned hardware header size, but not enough for the aligned one, and that we warn if we hit this condition. ==================== Signed-off-by: NDavid S.

While skb_push() makes the kernel panic if the skb headroom is less than the unaligned hardware header size, it will proceed normally in case we copy more than that because of alignment, and we'll silently corrupt adjacent slabs. In the case fixed by the previous patch, "ipv6: Check available headroom in ip6_xmit() even without options", we end up in neigh_hh_output() with 14 bytes headroom, 14 bytes hardware header and write 16 bytes, starting 2 bytes before the allocated buffer. Always check we're not writing before skb->head and, if the headroom is not enough, warn and drop the packet. v2: - instead of panicking with BUG_ON(), WARN_ON_ONCE() and drop the packet (Eric Dumazet) - if we avoid the panic, though, we need to explicitly check the headroom before the memcpy(), otherwise we'll have corrupted slabs on a running kernel, after we warn - use __skb_push() instead of skb_push(), as the headroom check is already implemented here explicitly (Eric Dumazet) Signed-off-by: NStefano Brivio <sbrivio@redhat.com> Signed-off-by: NDavid S.

Even if we send an IPv6 packet without options, MAX_HEADER might not be enough to account for the additional headroom required by alignment of hardware headers. On a configuration without HYPERV_NET, WLAN, AX25, and with IPV6_TUNNEL, sending short SCTP packets over IPv4 over L2TP over IPv6, we start with 100 bytes of allocated headroom in sctp_packet_transmit(), end up with 54 bytes after l2tp_xmit_skb(), and 14 bytes in ip6_finish_output2(). Those would be enough to append our 14 bytes header, but we're going to align that to 16 bytes, and write 2 bytes out of the allocated slab in neigh_hh_output().

tcp_tso_should_defer() can return true in three different cases : 1) We are cwnd-limited 2) We are rwnd-limited 3) We are application limited. Neal pointed out that my recent fix went too far, since it assumed that if we were not in 1) case, we must be rwnd-limited Fix this by properly populating the is_cwnd_limited and is_rwnd_limited booleans. After this change, we can finally move the silly check for FIN flag only for the application-limited case. The same move for EOR bit will be handled in net-next, since commit 1c09f7d0 ("tcp: do not try to defer skbs with eor mark (MSG_EOR)") is scheduled for linux-4.21 Tested by running 200 concurrent netperf -t TCP_RR -- -r 60000,100 and checking none of them was rwnd_limited in the chrono_stat output from "ss -ti" command.
