https://gitlab.freedesktop.org/drm/msm into drm-next Take 2 of msm-next pull, this version drops the OPP patch due to [1], so I'll send the gpu opp/bw scaling patch after the OPP patch lands. Since I had to force-push I took the opportunity to rebase on drm-next, and since you already merged in 5.8-rc6 a few fixes from the last cycle dropped out. This time around: * A bunch more a650/a640 (sm8150/sm8250) display and GPU enablement and fixes * Enable dpu dither block for 6bpc panels * dpu suspend fixes * dpu fix for cursor on 2nd display * dsi/mdp5 enablement for sdm630/sdm636/sdm660 I also regenerated the register headers, which accounts for a good bit of the size this time, because we hadn't re-synced the register headers since the early days of a6xx bringup.

2020-08-04drm: fix drm_dp_mst_port refcount leaks in drm_dp_mst_allocate_vcpiXin Xiong1-3/+4
drm_dp_mst_allocate_vcpi() invokes drm_dp_mst_topology_get_port_validated(), which increases the refcount of the "port". These reference counting issues take place in two exception handling paths separately. Either when “slots” is less than 0 or when drm_dp_init_vcpi() returns a negative value, the function forgets to reduce the refcnt increased drm_dp_mst_topology_get_port_validated(), which results in a refcount leak. Fix these issues by pulling up the error handling when "slots" is less than 0, and calling drm_dp_mst_topology_put_port() before termination when drm_dp_init_vcpi() returns a negative value.

2020-08-04fbmem: pull fbcon_update_vcs() out of fb_set_var()Tetsuo Handa4-12/+7
syzbot is reporting OOB read bug in vc_do_resize() [1] caused by memcpy() based on outdated old_{rows,row_size} values, for resize_screen() can recurse into vc_do_resize() which changes vc->vc_{cols,rows} that outdates old_{rows,row_size} values which were saved before calling resize_screen(). Daniel Vetter explained that resize_screen() should not recurse into fbcon_update_vcs() path due to FBINFO_MISC_USEREVENT being still set when calling resize_screen(). Instead of masking FBINFO_MISC_USEREVENT before calling fbcon_update_vcs(), we can remove FBINFO_MISC_USEREVENT by calling fbcon_update_vcs() only if fb_set_var() returned 0. This change assumes that it is harmless to call fbcon_update_vcs() when fb_set_var() returned 0 without reaching fb_notifier_call_chain().

2020-08-01vxlan: fix memleak of fdbTaehee Yoo1-2/+4
When vxlan interface is deleted, all fdbs are deleted by vxlan_flush(). vxlan_flush() flushes fdbs but it doesn't delete fdb, which contains all-zeros-mac because it is deleted by vxlan_uninit(). But vxlan_uninit() deletes only the fdb, which contains both all-zeros-mac and default vni. So, the fdb, which contains both all-zeros-mac and non-default vni will not be deleted.

2020-08-01Revert "kconfig: qconf: don't show goback button on splitMode"Masahiro Yamada1-3/+2
This reverts commit cc1c08edccaf5317d99a17a3231fe06381044e83. Maxim Levitsky reports 'make xconfig' crashes since that commit (https://lkml.org/lkml/2020/7/18/411) Or, the following is simple test code that makes it crash: menu "Menu" config FOO bool "foo" default y menuconfig BAR bool "bar" depends on FOO endmenu Select the Split View mode, and double-click "bar" in the right window, then you will see Segmentation fault. When 'last' is not set for symbolMode, the following code in ConfigList::updateList() calls firstChild(). item = last ? last->nextSibling() : firstChild(); However, the pointer returned by ConfigList::firstChild() does not seem to be compatible with (ConfigItem *), which seems another bug. I'd rather want to reconsider whether hiding the goback icon is the right thing to do. In the following test code, the Split View shows "Menu2" and "Menu3" in the right window. You can descend into "Menu3", but there is no way to ascend back to "Menu2" from "Menu3". menu "Menu1" config FOO bool "foo" default y menu "Menu2" depends on FOO menu "Menu3" config BAZ bool "baz" endmenu endmenu endmenu It is true that the goback button is currently not functional due to yet another bug, but hiding the problem is not the right way to go. Anyway, Segmentation fault is fatal. Revert the offending commit for now, and we should find the right solution.

2020-08-01Revert "kconfig: qconf: Change title for the item window"Masahiro Yamada1-9/+1
This reverts commit 5752ff07fd90d764d96e3c586cc95c09598abfdd. It added dead code to ConfigList:ConfigList(). The constructor of ConfigList has the initializer, mode(singleMode). if (mode == symbolMode) setHeaderLabels(QStringList() << "Item" << "Name" << "N" << "M" << "Y" << "Value"); else setHeaderLabels(QStringList() << "Option" << "Name" << "N" << "M" << "Y" << "Value"); ... always takes the else part. The change to ConfigList::updateSelection() is strange too. When you click the split view icon for the first time, the titles in both windows show "Option". After you click something in the right window, the title suddenly changes to "Item". ConfigList::updateSelection() is not the right place to do this, at least. It was not a good idea, I think.

We've added 5 non-merge commits during the last 21 day(s) which contain a total of 5 files changed, 126 insertions(+), 18 deletions(-). The main changes are: 1) Fix a map element leak in HASH_OF_MAPS map type, from Andrii Nakryiko. 2) Fix a NULL pointer dereference in __btf_resolve_helper_id() when no btf_vmlinux is available, from Peilin Ye. 3) Init pos variable in __bpfilter_process_sockopt(), from Christoph Hellwig. 4) Fix a cgroup sockopt verifier test by specifying expected attach type, from Jean-Philippe Brucker. Note that when net gets merged into net-next later on, there is a small merge conflict in kernel/bpf/btf.c between commit 5b801dfb7feb ("bpf: Fix NULL pointer dereference in __btf_resolve_helper_id()") from the bpf tree and commit 138b9a0511c7 ("bpf: Remove btf_id helpers resolving") from the net-next tree. Resolve as follows: remove the old hunk with the __btf_resolve_helper_id() function. Change the btf_resolve_helper_id() so it actually tests for a NULL btf_vmlinux and bails out: int btf_resolve_helper_id(struct bpf_verifier_log *log, const struct bpf_func_proto *fn, int arg) { int id; if (fn->arg_type[arg] != ARG_PTR_TO_BTF_ID || !btf_vmlinux) return -EINVAL; id = fn->btf_id[arg]; if (!id || id > btf_vmlinux->nr_types) return -EINVAL; return id; } Let me know if you run into any others issues (CC'ing Jiri Olsa so he's in the loop with regards to merge conflict resolution). ==================== Signed-off-by: David S.

From Xin Long. 2) Several fixes for the new ESP in TCP encapsulation. From Sabrina Dubroca. 3) Fix crash when the hold queue is used. The assumption that xdst->path and dst->child are not a NULL pointer only if dst->xfrm is not a NULL pointer is true with the exception of using the hold queue. Fix this by checking for hold queue usage before dereferencing xdst->path or dst->child. 4) Validate pfkey_dump parameter before sending them. From Mark Salyzyn. 5) Fix the location of the transport header with ESP in UDPv6 encapsulation. From Sabrina Dubroca. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2020-08-01rds: Prevent kernel-infoleak in rds_notify_queue_get()Peilin Ye1-1/+2
rds_notify_queue_get() is potentially copying uninitialized kernel stack memory to userspace since the compiler may leave a 4-byte hole at the end of `cmsg`. In 2016 we tried to fix this issue by doing `= { 0 };` on `cmsg`, which unfortunately does not always initialize that 4-byte hole. Fix it by using memset() instead.

This isn't something that ever changes between planes, so move it to dpu_caps struct. Making this change will allow more re-use in the "SSPP sub blocks config" part of the catalog, in particular when adding support for SM8150 and SM8250 which have different max_linewidth. This also sets max_hdeci_exp/max_vdeci_exp to 0 for sc7180, as decimation is not supported on the newest DPU versions.

2020-07-31drm/msm/dpu: update UBWC config for sm8150 and sm8250Jonathan Marek6-90/+42
Update the UBWC registers to the right values for sm8150 and sm8250. This removes broken dpu_hw_reset_ubwc, which doesn't work because the "force blk offset to zero to access beginning of register region" hack is copied from downstream, where mapped region starts 0x1000 below what is used in the upstream driver. Also simplifies the overly complicated change that was introduced in e4f9bbe9f8beab9a1ce4 to work around dpu_hw_reset_ubwc being broken.
