The introduction of IFLA_VXLAN_RESERVED_BITS led to - IFLA_VXLAN_FAN_MAP's integer value being incremented by 1 (33 to 34). - Thus the presence of attribute IFLA_VXLAN_FAN_MAP is checked but parsing - of the fan-map is attempted by accessing IFLA_IPTUN_FAN_MAP, causing a - NULL pointer dereference when creating a VXLAN device with a Fan - mapping. - - This is resolved by adjusting the vxlan_parse_fan_map() function to - access the correct IFLA_VXLAN_FAN_MAP attribute instead of - IFLA_IPTUN_FAN_MAP. - - Fixes: 9ce64bb8afd8 ("UBUNTU: SAUCE: fan: add VXLAN implementation") - Signed-off-by: Jacob Martin <jacob.mar...@canonical.com> + Manny Pacquiao vs. Mario Barrios start time + Date: Saturday, July 19 - [Test Plan] + Time: 8 p.m. ET | 5 p.m. PT - The NULL pointer dereference can be reproduced 100% of the time with the - following: - # ip link add vxlan0 type vxlan dstport 0 local 192.168.0.1 id 16384000 fan-map 240.0.0.0/8:192.168.0.0/16 + Main event start time (approx.): 11:15 p.m. ET | 8:15 p.m. PT - Thus, this can be used to easily verify the issue was resolved. + Location: MGM Grand Garden Arena - Las Vegas - I also ran the ubuntu_fan_smoke_test autotest test after patching the - kernel, and verified that it now passes. + Manny Pacquiao vs. Mario Barrios airs on July 19 at the MGM Grand Garden + Arena in Las Vegas. The main card starts at 8 p.m. ET. The main event + should begin around 11:15 p.m. ET, depending on how long the undercard + fights last. - [Where problems could occur] + Pacquiao (62-8-2) is a multi-division champion. The former Senator of + the Philippines has faced the best boxing has to offer since turning pro + in 1995. The 46-year-old retired following a loss against Yordenis Ugas + in 2021 and has since competed in exhibition fights. - This change affects the vxlan driver, specifically the code that parses - an optional Ubuntu Fan configuration. Issues could manifest as - misbehavior of the vxlan driver. + Coming out of retirement doesnโt always end well for veterans. Pacquiao + attempts to prove he still has what it takes as he re-enters the ring. - -------------- above SRU justification added by ~jacobmartin - -------------- + "Iโve been able to rest my body, and itโs been good for me. Now Iโm + back, and Iโm excited to give the fans a great fight. I know that + Barrios is training hard to defend his belt. Iโm the challenger, so I + know I have to go the extra mile and punish myself in training to win + the fight. Thatโs the goal," Pacquiao said. - SRU cycle 2025.05.19 regression test results showed a kernel panic - caused by test ubuntu_fan_smoke_test:sut-scan for plucky:linux-gcp - 6.14.0-1008.8 + The 30-year-old Barrios (29-2-1) has gone 3-0-1 since losing against + Gervonta Davis and Keith Thurman. He beat Yordenis Ugas for interim gold + and became full-time champion after Terence Crawford was named "champion + in recess." - The failure was subsequently determined to affect the generic kernel as - well. + Making new fans after fighting Abel Ramos to a draw in an entertaining + affair, Barrios will have a brighter spotlight on him when he faces + Pacquiao. Barrios looks to put on a show against the Hall of Famer. - [ 1012.062312] BUG: kernel NULL pointer dereference, address: 0000000000000000 - [ 1012.069603] #PF: supervisor read access in kernel mode - [ 1012.074864] #PF: error_code(0x0000) - not-present page - [ 1012.080097] PGD 0 P4D 0 - [ 1012.082728] Oops: Oops: 0000 [#1] SMP NOPTI - [ 1012.087010] CPU: 2 UID: 0 PID: 4687 Comm: ip Not tainted 6.14.0-1008-gcp #8-Ubuntu - [ 1012.094688] Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 05/29/2025 - [ 1012.104000] RIP: 0010:vxlan_nl2conf+0xa5/0xff0 [vxlan] - [ 1012.109256] Code: 48 85 c0 0f 84 4c 06 00 00 8b 40 04 89 43 04 b8 02 00 00 00 66 89 03 49 83 bc 24 10 01 00 00 00 74 6d 49 8b 84 24 08 01 00 00 <0f> b7 38 8d 57 fc 0f b7 d2 83 fa 03 7e 57 49 81 c2 80 0a 00 00 48 - [ 1012.128119] RSP: 0018:ffffa1f802c63380 EFLAGS: 00010286 - [ 1012.133439] RAX: 0000000000000000 RBX: ffffa1f802c63418 RCX: 0000000000000000 - [ 1012.140668] RDX: ffff95bcce0d2000 RSI: 0000000000000000 RDI: ffffa1f802c63490 - [ 1012.147898] RBP: ffffa1f802c63400 R08: 0000000000000000 R09: ffffa1f802c63760 - [ 1012.155128] R10: ffff95bcce0d2000 R11: 0000000000000000 R12: ffff95bd2f144a48 - [ 1012.162356] R13: ffffa1f802c63760 R14: 00ffffff00000008 R15: 0000000000000000 - [ 1012.169588] FS: 00007eb23310c840(0000) GS:ffff95cbbf700000(0000) knlGS:0000000000000000 - [ 1012.177777] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 - [ 1012.183618] CR2: 0000000000000000 CR3: 000000015b6a3002 CR4: 0000000000370ef0 - [ 1012.190850] Call Trace: - [ 1012.193393] <TASK> - [ 1012.195589] ?
