Steffen Klassert says: ==================== pull request (net): ipsec 2021-08-04 1) Fix a sysbot reported memory leak in xfrm_user_rcv_msg. From Pavel Skripkin. 2) Revert "xfrm: policy: Read seqcount outside of rcu-read side in xfrm_policy_lookup_bytype". This commit tried to fix a lockin bug, but only cured some of the symptoms. A proper fix is applied on top of this revert. 3) Fix a locking bug on xfrm state hash resize. A recent change on sequence counters accidentally repaced a spinlock by a mutex. Fix from Frederic Weisbecker. 4) Fix possible user-memory-access in xfrm_user_rcv_msg_compat(). From Dmitry Safonov. 5) Add initialiation sefltest fot xfrm_spdattr_type_t.

selftests/sgx: Fix Q1 and Q2 calculation in sigstruct.c

2021-07-30T23:20:01Z

Q1 and Q2 are numbers with *maximum* length of 384 bytes. If the calculated length of Q1 and Q2 is less than 384 bytes, things will go wrong. E.g. if Q2 is 383 bytes, then 1. The bytes of q2 are copied to sigstruct->q2 in calc_q1q2(). 2. The entire sigstruct->q2 is reversed, which results it being 256 * Q2, given that the last byte of sigstruct->q2 is added to before the bytes given by calc_q1q2(). Either change in key or measurement can trigger the bug. E.g. an unmeasured heap could cause a devastating change in Q1 or Q2. Reverse exactly the bytes of Q1 and Q2 in calc_q1q2() before returning to the caller.
