[PATCH openEuler-1.0-LTS 1/2] l2tp: Serialize access to sk_user_data with sk_callback_lock
by Yongqiang Liu 05 Dec '22

From: Jakub Sitnicki <jakub(a)cloudflare.com> mainline inclusion from mainline-v6.1-rc6 commit b68777d54fac21fc833ec26ea1a2a84f975ab035 category: bugfix bugzilla: 188056, https://gitee.com/src-openeuler/kernel/issues/I62RNU CVE: CVE-2022-4129 -------------------------------- sk->sk_user_data has multiple users, which are not compatible with each other. Writers must synchronize by grabbing the sk->sk_callback_lock. l2tp currently fails to grab the lock when modifying the underlying tunnel socket fields. Fix it by adding appropriate locking. We err on the side of safety and grab the sk_callback_lock also inside the sk_destruct callback overridden by l2tp, even though there should be no refs allowing access to the sock at the time when sk_destruct gets called. v4: - serialize write to sk_user_data in l2tp sk_destruct v3: - switch from sock lock to sk_callback_lock - document write-protection for sk_user_data v2: - update Fixes to point to origin of the bug - use real names in Reported/Tested-by tags Cc: Tom Parkin <tparkin(a)katalix.com> Fixes: 3557baabf280 ("[L2TP]: PPP over L2TP driver core") Reported-by: Haowei Yan <g1042620637(a)gmail.com> Signed-off-by: Jakub Sitnicki <jakub(a)cloudflare.com> Signed-off-by: David S.
