2020-04-24ALSA: pcm: oss: Place the plugin buffer overflow checks correctly (for 5.7)Takashi Iwai
[ This is again a forward-port of the fix applied for 5.6-base code (commit 4285de0725b1) to 5.7-base, hence neither Fixes nor Cc-to-stable tags are included here -- tiwai ] The checks of the plugin buffer overflow in the previous fix by commit f2ecf903ef06 ("ALSA: pcm: oss: Avoid plugin buffer overflow") are put in the wrong places mistakenly, which leads to the expected (repeated) sound when the rate plugin is involved. Fix in the right places. Also, at those right places, the zero check is needed for the termination node, so added there as well, and let's get it done, finally.

2020-04-24afs: Fix to actually set AFS_SERVER_FL_HAVE_EPOCHDavid Howells
AFS keeps track of the epoch value from the rxrpc protocol to note (a) when a fileserver appears to have restarted and (b) when different endpoints of a fileserver do not appear to be associated with the same fileserver (ie. all probes back from a fileserver from all of its interfaces should carry the same epoch). However, the AFS_SERVER_FL_HAVE_EPOCH flag that indicates that we've received the server's epoch is never set, though it is used. Fix this to set the flag when we first receive an epoch value from a probe sent to the filesystem client from the fileserver.

2020-04-24dt-bindings: Fix command line length limit calling dt-mk-schemaRob Herring
As the number of schemas has increased, we're starting to hit the error "execvp: /bin/sh: Argument list too long". This is due to passing all the schema files on the command line to dt-mk-schema. It currently is only with out of tree builds and is intermittent depending on the file path lengths. Commit 2ba06cd8565b ("kbuild: Always validate DT binding examples") made hitting this proplem more likely since the example validation now always gets the full list of schemas. Fix this by passing the schema file list in a pipe and using xargs. We end up doing the find twice, but the time is insignificant compared to the dt-mk-schema time.

2020-04-24drm/amd/display: Fix green screen issue after suspendRodrigo Siqueira
[why] We have seen a green screen after resume from suspend in a Raven system connected with two displays (HDMI and DP) on X based system. We noticed that this issue is related to bad DCC metadata from user space which may generate hangs and consequently an underflow on HUBP. After taking a deep look at the code path we realized that after resume we try to restore the commit with the DCC enabled framebuffer but the framebuffer is no longer valid. [how] This problem was only reported on Raven based system and after suspend, for this reason, this commit adds a new parameter on fill_plane_dcc_attributes() to give the option of disabling DCC programmatically. In summary, for disabling DCC we first verify if is a Raven system and if it is in suspend; if both conditions are true we disable DCC temporarily, otherwise, it is enabled.

When fixing the initialization race, we neglected to account for the fact that debugfs is initialized in wiphy_register(), and some debugfs things went missing (or rather were rerooted to the global debugfs root). Fix this by adding debugfs entries only after wiphy_register().

2020-04-24ALSA: hda: Match both PCI ID and SSID for driver blacklistTakashi Iwai
The commit 3c6fd1f07ed0 ("ALSA: hda: Add driver blacklist") added a new blacklist for the devices that are known to have empty codecs, and one of the entries was ASUS ROG Zenith II (PCI SSID 1043:874f). However, it turned out that the very same PCI SSID is used for the previous model that does have the valid HD-audio codecs and the change broke the sound on it. Since the empty codec problem appear on the certain AMD platform (PCI ID 1022:1487), this patch changes the blacklist matching to both PCI ID and SSID using pci_match_id(). Also, the entry that was removed by the previous fix for ASUS ROG Zenigh II is re-added.

To make LDLIBS parsing easier - change gpio and memfd Makefiles to use the same temporary variable used to find and add libraries to LDLIBS. - simlify LDLIBS append logic in intel_pstate/Makefile.

2020-04-23selftests/ftrace: Check required filter files before running testXiao Yang
Without CONFIG_DYNAMIC_FTRACE, some tests get failure because required filter files(set_ftrace_filter/available_filter_functions/stack_trace_filter) are missing. So implement check_filter_file() and make all related tests check required filter files by it. BTW: set_ftrace_filter and available_filter_functions are introduced together so just check either of them.

2020-04-23net: meth: remove spurious copyright textJonathan Corbet
Evidently, at some point in the pre-githistorious past, drivers/net/ethernet/sgi/meth.h somehow contained some code from the "snull" driver from the Linux Device Drivers book. A comment crediting that source, asserting copyright ownership by the LDD authors, and imposing the LDD2 license terms was duly added to the file. Any code that may have been derived from snull is long gone, and the distribution terms are not GPL-compatible. Since the copyright claim is not based in fact (if it ever was), simply remove it and the distribution terms as well.

2020-04-23net/x25: Fix x25_neigh refcnt leak when receiving frameXiyu Yang
x25_lapb_receive_frame() invokes x25_get_neigh(), which returns a reference of the specified x25_neigh object to "nb" with increased refcnt. When x25_lapb_receive_frame() returns, local variable "nb" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in one path of x25_lapb_receive_frame(). When pskb_may_pull() returns false, the function forgets to decrease the refcnt increased by x25_get_neigh(), causing a refcnt leak. Fix this issue by calling x25_neigh_put() when pskb_may_pull() returns false.

2020-04-23mlxsw: Fix some IS_ERR() vs NULL bugsDan Carpenter
The mlxsw_sp_acl_rulei_create() function is supposed to return an error pointer from mlxsw_afa_block_create(). The problem is that these functions both return NULL instead of error pointers. Half the callers expect NULL and half expect error pointers so it could lead to a NULL dereference on failure. This patch changes both of them to return error pointers and changes all the callers which checked for NULL to check for IS_ERR() instead.
