Below commit claims that atlantic NIC requires to reset the device on pm op, and had set the deep to true for all suspend/resume functions. commit 1809c30b6e5a ("net: atlantic: always deep reset on pm op, fixing up my null deref regression") So, we could remove deep parameter on suspend/resume functions without any functional change.

2022-07-14sfc: fix kernel panic when creating VFÍñigo Huguet1-0/+3
When creating VFs a kernel panic can happen when calling to efx_ef10_try_update_nic_stats_vf. When releasing a DMA coherent buffer, sometimes, I don't know in what specific circumstances, it has to unmap memory with vunmap. It is disallowed to do that in IRQ context or with BH disabled. Otherwise, we hit this line in vunmap, causing the crash: BUG_ON(in_interrupt()); This patch reenables BH to release the buffer.

2022-07-14Merge branch 'seg6-fix-skb-checksum-for-srh-encapsulation-insertion'Paolo Abeni3-4/+4
Andrea Mayer says: ==================== seg6: fix skb checksum for SRH encapsulation/insertion The Linux kernel supports Segment Routing Header (SRH) encapsulation/insertion operations by providing the capability to: i) encapsulate a packet in an outer IPv6 header with a specified SRH; ii) insert a specified SRH directly after the IPv6 header of the packet. Note that the insertion operation is also referred to as 'injection'. The two operations are respectively supported by seg6_do_srh_encap() and seg6_do_srh_inline(), which operate on the skb associated to the packet as needed (e.g. adding the necessary headers and initializing them, while taking care to recalculate the skb checksum). seg6_do_srh_encap() and seg6_do_srh_inline() do not initialize the payload length of the IPv6 header, which is carried out by the caller functions. However, this approach causes the corruption of the skb checksum which needs to be updated only after initialization of headers is completed (thanks to Paolo Abeni for detecting this issue). The patchset fixes the skb checksum corruption by moving the IPv6 header payload length initialization from the callers of seg6_do_srh_encap() and seg6_do_srh_inline() directly into these functions. This patchset is organized as follows: - patch 1/3, seg6: fix skb checksum evaluation in SRH encapsulation/insertion; (* SRH encapsulation/insertion available since v4.10) - patch 2/3, seg6: fix skb checksum in SRv6 End.B6 and End.B6.Encaps behaviors; (* SRv6 End.B6 and End.B6.Encaps behaviors available since v4.14) - patch 3/3, seg6: bpf: fix skb checksum in bpf_push_seg6_encap(); (* bpf IPv6 Segment Routing helpers available since v4.18) ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Paolo Abeni <[email protected]>
2022-07-14seg6: bpf: fix skb checksum in bpf_push_seg6_encap()Andrea Mayer1-1/+0
Both helper functions bpf_lwt_seg6_action() and bpf_lwt_push_encap() use the bpf_push_seg6_encap() to encapsulate the packet in an IPv6 with Segment Routing Header (SRH) or insert an SRH between the IPv6 header and the payload. To achieve this result, such helper functions rely on bpf_push_seg6_encap() which, in turn, leverages seg6_do_srh_{encap,inline}() to perform the required operation (i.e. encap/inline). This patch removes the initialization of the IPv6 header payload length from bpf_push_seg6_encap(), as it is now handled properly by seg6_do_srh_{encap,inline}() to prevent corruption of the skb checksum.

2022-07-14seg6: fix skb checksum in SRv6 End.B6 and End.B6.Encaps behaviorsAndrea Mayer1-2/+0
The SRv6 End.B6 and End.B6.Encaps behaviors rely on functions seg6_do_srh_{encap,inline}() to, respectively: i) encapsulate the packet within an outer IPv6 header with the specified Segment Routing Header (SRH); ii) insert the specified SRH directly after the IPv6 header of the packet. This patch removes the initialization of the IPv6 header payload length from the input_action_end_b6{_encap}() functions, as it is now handled properly by seg6_do_srh_{encap,inline}() to avoid corruption of the skb checksum.

2022-07-14seg6: fix skb checksum evaluation in SRH encapsulation/insertionAndrea Mayer1-1/+4
Support for SRH encapsulation and insertion was introduced with commit 6c8702c60b88 ("ipv6: sr: add support for SRH encapsulation and injection with lwtunnels"), through the seg6_do_srh_encap() and seg6_do_srh_inline() functions, respectively. The former encapsulates the packet in an outer IPv6 header along with the SRH, while the latter inserts the SRH between the IPv6 header and the payload. Then, the headers are initialized/updated according to the operating mode (i.e., encap/inline). Finally, the skb checksum is calculated to reflect the changes applied to the headers. The IPv6 payload length ('payload_len') is not initialized within seg6_do_srh_{inline,encap}() but is deferred in seg6_do_srh(), i.e. the caller of seg6_do_srh_{inline,encap}(). However, this operation invalidates the skb checksum, since the 'payload_len' is updated only after the checksum is evaluated. To solve this issue, the initialization of the IPv6 payload length is moved from seg6_do_srh() directly into the seg6_do_srh_{inline,encap}() functions and before the skb checksum update takes place.

2022-07-14netfs: do not unlock and put the folio twiceXiubo Li5-17/+23
check_write_begin() will unlock and put the folio when return non-zero. So we should avoid unlocking and putting it twice in netfs layer. Change the way ->check_write_begin() works in the following two ways: (1) Pass it a pointer to the folio pointer, allowing it to unlock and put the folio prior to doing the stuff it wants to do, provided it clears the folio pointer. (2) Change the return values such that 0 with folio pointer set means continue, 0 with folio pointer cleared means re-get and all error codes indicating an error (no special treatment for -EAGAIN).

2022-07-13fs/remap: constrain dedupe of EOF blocksDave Chinner1-1/+2
If dedupe of an EOF block is not constrainted to match against only other EOF blocks with the same EOF offset into the block, it can match against any other block that has the same matching initial bytes in it, even if the bytes beyond EOF in the source file do not match. Fix this by constraining the EOF block matching to only match against other EOF blocks that have identical EOF offsets and data. This allows "whole file dedupe" to continue to work without allowing eof blocks to randomly match against partial full blocks with the same data.

2022-07-13drm/amd/display: Only use depth 36 bpp linebuffers on DCN display engines.Mario Kleiner1-5/+6
Various DCE versions had trouble with 36 bpp lb depth, requiring fixes, last time in commit 353ca0fa5630 ("drm/amd/display: Fix 10bit 4K display on CIK GPUs") for DCE-8. So far >= DCE-11.2 was considered ok, but now I found out that on DCE-11.2 it causes dithering when there shouldn't be any, so identity pixel passthrough with identity gamma LUTs doesn't work when it should. This breaks various important neuroscience applications, as reported to me by scientific users of Polaris cards under Ubuntu 22.04 with Linux 5.15, and confirmed by testing it myself on DCE-11.2. Lets only use depth 36 for DCN engines, where my testing showed that it is both necessary for high color precision output, e.g., RGBA16 fb's, and not harmful, as far as more than one year in real-world use showed. DCE engines seem to work fine for high precision output at 30 bpp, so this ("famous last words") depth 30 should hopefully fix all known problems without introducing new ones. Successfully retested on DCE-11.2 Polaris and DCN-1.0 Raven Ridge on top of Linux 5.19.0-rc2 + drm-next.

2022-07-13sysctl: Fix data-races in proc_dointvec_ms_jiffies().Kuniyuki Iwashima1-4/+4
A sysctl variable is accessed concurrently, and there is always a chance of data-race. So, all readers and writers need some basic protection to avoid load/store-tearing. This patch changes proc_dointvec_ms_jiffies() to use READ_ONCE() and WRITE_ONCE() internally to fix data-races on the sysctl side. For now, proc_dointvec_ms_jiffies() itself is tolerant to a data-race, but we still need to add annotations on the other subsystem's side.

On a HP 288 Pro G2 MT (X9W02AV), the front mic could not be detected. In order to get it working, the pin configuration needs to be set correctly, and the ALC221_FIXUP_HP_288PRO_MIC_NO_PRESENCE fixup needs to be applied.
