+Subject: net: rds: fix MR cleanup on copy error
+
+From: Ao Zhou <draw51280@163.com>
+
+commit 8141a2dc70080eda1aedc0389ed2db2b292af5bd upstream.
+
+__rds_rdma_map() hands sg/pages ownership to the transport after
+get_mr() succeeds. If copying the generated cookie back to user space
+fails after that point, the error path must not free those resources
+again before dropping the MR reference.
+
+Remove the duplicate unpin/free from the put_user() failure branch so
+that MR teardown is handled only through the existing final cleanup
+path.
+
+Fixes: 0d4597c8c5ab ("net/rds: Track user mapped pages through special API")

+Subject: net/smc: avoid early lgr access in smc_clc_wait_msg
+
+From: Ruijie Li <ruijieli51@gmail.com>
+
+commit 5a8db80f721deee8e916c2cfdee78decda02ce4f upstream.
+
+A CLC decline can be received while the handshake is still in an early
+stage, before the connection has been associated with a link group.
+
+The decline handling in smc_clc_wait_msg() updates link-group level sync
+state for first-contact declines, but that state only exists after link
+group setup has completed. Guard the link-group update accordingly and
+keep the per-socket peer diagnosis handling unchanged.
+
+This preserves the existing sync_err handling for established link-group
+contexts and avoids touching link-group state before it is available.
+
+Fixes: 0cfdd8f92cac ("smc: connection and link group creation")

+Subject: RDMA/rxe: Validate pad and ICRC before payload_size() in rxe_rcv
+
+From: hkbinbin <hkbinbinbin@gmail.com>
+
+commit 7244491dab347f648e661da96dc0febadd9daec3 upstream.
+
+rxe_rcv() currently checks only that the incoming packet is at least
+header_size(pkt) bytes long before payload_size() is used.
+
+However, payload_size() subtracts both the attacker-controlled BTH pad
+field and RXE_ICRC_SIZE from pkt->paylen:
+
+ payload_size = pkt->paylen - offset[RXE_PAYLOAD] - bth_pad(pkt)
+ - RXE_ICRC_SIZE
+
+This means a short packet can still make payload_size() underflow even
+if it includes enough bytes for the fixed headers. Simply requiring
+header_size(pkt) + RXE_ICRC_SIZE is not sufficient either, because a
+packet with a forged non-zero BTH pad can still leave payload_size()
+negative and pass an underflowed value to later receive-path users.
+
+Fix this by validating pkt->paylen against the full minimum length
+required by payload_size(): header_size(pkt) + bth_pad(pkt) +
+RXE_ICRC_SIZE.

+
+commit 6f1d4d2ecfcd1b577dc87350ea965fe81f272e83 upstream.
+
+Outside of the EFI tpm code, the TPM_MEMREMAP()/TPM_MEMUNMAP functions are
+defined as trivial macros, leading to the mapping_size variable ending
+up unused:

+ 167 | int mapping_size;
+
+Turn the stubs into inline functions to avoid this warning.
