RACK skips an ACK unless it advances the most recently delivered TX timestamp (rack.mstamp). Since RACK also uses the most recent RTT to decide if a packet is lost, RACK should still run the loss detection whenever the most recent RTT changes. For example, an ACK that does not advance the timestamp but triggers the cwnd undo due to reordering, would then use the most recent (higher) RTT measurement to detect further losses.

When sender detects spurious retransmission, all packets marked lost are remarked to be in-flight. However some may be considered lost based on its timestamps in RACK.

RACK does not test the loss recovery state correctly to compute the reordering window. It assumes if lost_out is zero then TCP is not in loss recovery. But it can be zero during recovery before calling tcp_rack_detect_loss(): when an ACK acknowledges all packets marked lost before receiving this ACK, but has not yet to discover new ones by tcp_rack_detect_loss(). The fix is to simply test the congestion state directly.

Fix BBR so that upon notification of a loss recovery undo BBR resets long-term bandwidth sampling. Under high reordering, reordering events can be interpreted as loss.

This commit records the "full bw reached" decision in a new full_bw_reached bit. This is a pure refactor that does not change the current behavior, but enables subsequent fixes and improvements. In particular, this enables simple and clean fixes because the full_bw and full_bw_cnt can be unconditionally zeroed without worrying about forgetting that we estimated we filled the pipe in Startup. And it enables future improvements because multiple code paths can be used for estimating that we filled the pipe in Startup; any new code paths only need to set this bit when they think the pipe is full. Note that this fix intentionally reduces the width of the full_bw_cnt counter, since we have never used the most significant bit.

If an overlay has no "__symbols__" node, but it has nodes without "__overlay__" subnodes at the end (e.g. a "__fixups__" node), after filling in all fragments for nodes with "__overlay__" subnodes, "fragment = &fragments[cnt]" will point beyond the end of the allocated array. Hence writing to "fragment->overlay" will overwrite unallocated memory, which may lead to a crash later. Fix this by deferring both the assignment to "fragment" and the offending write afterwards until we know for sure the node has an "__overlay__" subnode, and thus a valid entry in "fragments[]".

->pkey_algo used to be an enum, but was changed to a string by commit 4e8ae72a ("X.509: Make algo identifiers text instead of enum"). But two comparisons were not updated. Fix them to use strcmp(). This bug broke signature verification in certain configurations, depending on whether the string constants were deduplicated or not.

keyctl_restrict_keyring() allows through a NULL restriction when the "type" is non-NULL, which causes a NULL pointer dereference in asymmetric_lookup_restriction() when it calls strcmp() on the restriction string. But no key types actually use a "NULL restriction" to mean anything, so update keyctl_restrict_keyring() to reject it with EINVAL.

Variable key_ref is being assigned a value that is never read; key_ref is being re-assigned a few statements later. Hence this assignment is redundant and can be removed.

In public_key_verify_signature(), if akcipher_request_alloc() fails, we return -ENOMEM. But that error code was set 25 lines above, and by accident someone could easily insert new code in between that assigns to 'ret', which would introduce a signature verification bypass. Make the code clearer by moving the -ENOMEM down to where it is used. Additionally, the callers of public_key_verify_signature() only consider a negative return value to be an error. This means that if any positive return value is accidentally introduced deeper in the call stack (e.g. 'return EBADMSG' instead of 'return -EBADMSG' somewhere in RSA), signature verification will be bypassed. Make things more robust by having public_key_verify_signature() warn about positive errors and translate them into -EINVAL.

pkcs7_validate_trust_one() used 'x509->next == x509' to identify a self-signed certificate. That's wrong; ->next is simply the link in the linked list of certificates in the PKCS#7 message. It should be checking ->signer instead. Fix it. Fortunately this didn't actually matter because when we re-visited 'x509' on the next iteration via 'x509->signer', it was already seen and not verified, so we returned -ENOKEY anyway.
