This is a scripted bug report about ADT failures while running linux tests for linux/5.8.0-56.63 on groovy. Whether this is caused by the dep8 tests of the tested source or the kernel has yet to be determined.

[Impact]
Upstream commit 6628ddfec7580882f11fdc5c194a8ea781fdadfa ("net: geneve: check skb is large enough for IPv4/IPv6 header"), applied to groovy/linux 5.8.0-56.63 via upstream stable update (bug 1929132) introduced a regression caught by kernel selftests, net.pmtu.sh testcase:
02:56:46 DEBUG| [stdout] # TEST: IPv6 over geneve4: PMTU exceptions - nexthop objects [ OK ]
02:56:48 DEBUG| [stdout] # TEST: IPv4 over geneve6: PMTU exceptions [FAIL]
02:56:48 DEBUG| [stdout] # PMTU exception wasn't created after exceeding link layer MTU on geneve interface
02:56:49 DEBUG| [stdout] # TEST: IPv4 over geneve6: PMTU exceptions - nexthop objects [FAIL]
[Fix]
The issue is fixed by d13f048dd40e8577260cd43faea8ec9b77520197 ("net: geneve: modify IP header check in geneve6_xmit_skb and geneve_xmit_skb"), which is already applied for the next SRU cycle as part of upstream stable update (bug 1930766).
[Tests]
I have applied the fix on top of 5.8.0-56.63 and ran pmtu.sh and the whole selftests.net suite. The testcase is now completed successfully and no other regression was found.
[Where problems could occur]
The fix could be a partial fix not covering all corner cases, this could lead to other failures with geneve tunnels.

[Impact]
Upstream commit 6628ddfec7580882f11fdc5c194a8ea781fdadfa ("net: geneve: check skb is large enough for IPv4/IPv6 header"), applied to groovy/linux 5.8.0-56.63 via upstream stable update (bug 1929132) introduced a regression caught by kernel selftests, net.pmtu.sh testcase:
02:56:46 DEBUG| [stdout] # TEST: IPv6 over geneve4: PMTU exceptions - nexthop objects [ OK ]
02:56:48 DEBUG| [stdout] # TEST: IPv4 over geneve6: PMTU exceptions [FAIL]
02:56:48 DEBUG| [stdout] # PMTU exception wasn't created after exceeding link layer MTU on geneve interface
02:56:49 DEBUG| [stdout] # TEST: IPv4 over geneve6: PMTU exceptions - nexthop objects [FAIL]
[Fix]
The issue is fixed by d13f048dd40e8577260cd43faea8ec9b77520197 ("net: geneve: modify IP header check in geneve6_xmit_skb and geneve_xmit_skb"), which is already applied for the next SRU cycle as part of upstream stable update (bug 1930766).
[Tests]
I have applied the fix on top of 5.8.0-56.63 and ran pmtu.sh and the whole selftests.net suite. The testcase is now completed successfully and no other regression was found.
[Where problems could occur]
The fix could be a partial fix not covering all corner cases, this could lead to other failures with geneve tunnels.
[Original Description]
This is a scripted bug report about ADT failures while running linux tests for linux/5.8.0-56.63 on groovy. Whether this is caused by the dep8 tests of the tested source or the kernel has yet to be determined.
Looks to be isolated to Groovy and appearing on all arches.

[Impact]
Upstream commit 6628ddfec7580882f11fdc5c194a8ea781fdadfa ("net: geneve: check skb is large enough for IPv4/IPv6 header"), applied to groovy/linux 5.8.0-56.63 via upstream stable update (bug 1929132) introduced a regression caught by kernel selftests, pmtu.sh from net testcase:
02:56:48 DEBUG| [stdout] # TEST: IPv4 over geneve6: PMTU exceptions [FAIL]
02:56:48 DEBUG| [stdout] # PMTU exception wasn't created after exceeding link layer MTU on geneve interface
02:56:49 DEBUG| [stdout] # TEST: IPv4 over geneve6: PMTU exceptions - nexthop objects [FAIL]
[Fix]
The issue is fixed by d13f048dd40e8577260cd43faea8ec9b77520197 ("net: geneve: modify IP header check in geneve6_xmit_skb and geneve_xmit_skb"), which is already applied for the next SRU cycle as part of upstream stable update (bug 1930766).
[Tests]
I have applied the fix on top of 5.8.0-56.63 and ran pmtu.sh and the whole selftests.net suite. The testcase is now completed successfully and no other regression was found.
[Where problems could occur]
The fix could be a partial fix not covering all corner cases, this could lead to other failures with geneve tunnels.
[Original Description]
This is a scripted bug report about ADT failures while running linux tests for linux/5.8.0-56.63 on groovy. Whether this is caused by the dep8 tests of the tested source or the kernel has yet to be determined.
Looks to be isolated to Groovy and appearing on all arches.

The issue is fixed by d13f048dd40e8577260cd43faea8ec9b77520197 ("net: geneve: modify IP header check in geneve6_xmit_skb and geneve_xmit_skb"), which is already applied for the next SRU cycle as part of upstream stable update (bug 1930766).
[Tests]
I have applied the fix on top of 5.8.0-56.63 and ran pmtu.sh and the whole selftests.net suite. The testcase is now completed successfully and no other regression was found.
[Where problems could occur]
The fix could be a partial fix not covering all corner cases, this could lead to other failures with geneve tunnels.
[Original Description]
This is a scripted bug report about ADT failures while running linux tests for linux/5.8.0-56.63 on groovy. Whether this is caused by the dep8 tests of the tested source or the kernel has yet to be determined.
Looks to be isolated to Groovy and appearing on all arches.
