AuthorDate: Tue Apr 27 18:18:36 2021 -0400

    kernel: bump 5.4 to 5.4.114
    
    Manually rebased*
      generic/backport-5.4/700-v5.5-net-core-allow-fast-GRO-for-skbs-with-Ethernet-heade.patch
    
    Added new backport*
      generic/backport-5.4/050-gro-fix-napi_gro_frags-Fast-GRO-breakage-due-to-IP-a.patch
    
    All others updated automatically.
    
    The new backport was included based on this[1] upstream commit that will be
    mainlined soon.  This change is needed because Eric Dumazet's check for
    NET_IP_ALIGN (landed in 5.4.114) causes huge slowdowns on drivers which use
    napi_gro_frags().
    
    Build system: x86_64
    Build-tested: ipq806x/R7800
    Run-tested: ipq806x/R7800
    
    No dmesg regressions, everything functional

+Subject: gro: fix napi_gro_frags() Fast GRO breakage due to IP
+ alignment check
+
+Commit 7ad18ff6449cbd6beb26b53128ddf56d2685aa93 upstream.
+
+Commit 38ec4944b593 ("gro: ensure frag0 meets IP header alignment")
+did the right thing, but missed the fact that napi_gro_frags() logics
+calls for skb_gro_reset_offset() *before* pulling Ethernet header
+to the skb linear space.
+That said, the introduced check for frag0 address being aligned to 4
+always fails for it as Ethernet header is obviously 14 bytes long,
+and in case with NET_IP_ALIGN its start is not aligned to 4.
+
+Fix this by adding @nhoff argument to skb_gro_reset_offset() which
+tells if an IP header is placed right at the start of frag0 or not.
+This restores Fast GRO for napi_gro_frags() that became very slow
+after the mentioned commit, and preserves the introduced check to
+avoid silent unaligned accesses.
+
+From v1 [0]:
+ - inline tiny skb_gro_reset_offset() to let the code be optimized
+   more efficively (esp. for the !NET_IP_ALIGN case) (Eric);
+ - pull in Reviewed-by from Eric.
