OVSDB_MONITOR_V3 -(i.e., "monitor_cond_since" method) with the initial monitor condition -MC1. - -Assuming the following two transactions are executed on the -ovsdb-server: -TXN1: "insert record R1 in table T1" -TXN2: "insert record R2 in table T2" - -If the client's monitor condition MC1 for table T2 matches R2 then the -client will receive the following update3 message: -method="update3", "insert record R2 in table T2", last-txn-id=TXN2 - -At this point, if the presence of the new record R2 in the IDL triggers -the client to update its monitor condition to MC2 and add a clause for -table T1 which matches R1, a monitor_cond_change message is sent to the -server: -method="monitor_cond_change", "clauses from MC2" - -In normal operation the ovsdb-server will reply with a new update3 -message of the form: -method="update3", "insert record R1 in table T1", last-txn-id=TXN2 - -However, if the connection drops in the meantime, this last update might -get lost. - -It might happen that during the reconnect a new transaction happens -that modifies the original record R1: -TXN3: "modify record R1 in table T1" - -When the client reconnects, it will try to perform a fast resync by -sending: -method="monitor_cond_since", "clauses from MC2", last-txn-id=TXN2 - -Because TXN2 is still in the ovsdb-server transaction history, the -server replies with the changes from the most recent transactions only, -i.e., TXN3: -result="true", last-txbb-id=TXN3, "modify record R1 in table T1" - -This causes the IDL on the client in to end up in an inconsistent -state because it has never seen the update that created R1. - -Such a scenario is described in: -https://bugzilla.redhat.com/show_bug.cgi?id=1808580#c22 - -To avoid this issue, the IDL will now maintain (up to) 3 different -types of conditions for each DB table: -- new_cond: condition that has been set by the IDL client but has - not yet been sent to the server through monitor_cond_change. -- req_cond: condition that has been sent to the server but the reply - acknowledging the change hasn't been received yet. -- ack_cond: condition that has been acknowledged by the server. - -Whenever the IDL FSM is restarted (e.g., voluntary or involuntary -disconnect): -- if there is a known last_id txn-id the code ensures that new_cond - will contain the most recent condition set by the IDL client - (either req_cond if there was a request in flight, or new_cond - if the IDL client set a condition while the IDL was disconnected) -- if there is no known last_id txn-id the code ensures that ack_cond will - contain the most recent conditions set by the IDL client regardless - whether they were acked by the server or not. - -When monitor_cond_since/monitor_cond requests are sent they will -always include ack_cond and if new_cond is not NULL a follow up -monitor_cond_change will be generated afterwards. - -On the other hand ovsdb_idl_db_set_condition() will always modify new_cond. - -This ensures that updates of type "insert" that happened before the last -transaction known by the IDL but didn't match old monitor conditions are -sent upon reconnect if the monitor condition has changed to include them -in the meantime. - -Fixes: 403a6a0cb003 ("ovsdb-idl: Fast resync from server when connection reset.") -Signed-off-by: Dumitru Ceara -Acked-by: Han Zhou -Signed-off-by: Ilya Maximets -(cherry picked from

May 2020 14:32:31 +0200 +Subject: [PATCH 3/4] ovsdb-idl: Avoid inconsistent IDL state with + OVSDB_MONITOR_V3. + +Assuming an ovsdb client connected to a database using OVSDB_MONITOR_V3 +(i.e., "monitor_cond_since" method) with the initial monitor condition +MC1. + +Assuming the following two transactions are executed on the +ovsdb-server: +TXN1: "insert record R1 in table T1" +TXN2: "insert record R2 in table T2" + +If the client's monitor condition MC1 for table T2 matches R2 then the +client will receive the following update3 message: +method="update3", "insert record R2 in table T2", last-txn-id=TXN2 + +At this point, if the presence of the new record R2 in the IDL triggers +the client to update its monitor condition to MC2 and add a clause for +table T1 which matches R1, a monitor_cond_change message is sent to the +server: +method="monitor_cond_change", "clauses from MC2" + +In normal operation the ovsdb-server will reply with a new update3 +message of the form: +method="update3", "insert record R1 in table T1", last-txn-id=TXN2 + +However, if the connection drops in the meantime, this last update might +get lost. + +It might happen that during the reconnect a new transaction happens +that modifies the original record R1: +TXN3: "modify record R1 in table T1" + +When the client reconnects, it will try to perform a fast resync by +sending: +method="monitor_cond_since", "clauses from MC2", last-txn-id=TXN2 + +Because TXN2 is still in the ovsdb-server transaction history, the +server replies with the changes from the most recent transactions only, +i.e., TXN3: +result="true", last-txbb-id=TXN3, "modify record R1 in table T1" + +This causes the IDL on the client in to end up in an inconsistent +state because it has never seen the update that created R1. + +Such a scenario is described in: +https://bugzilla.redhat.com/show_bug.cgi?id=1808580#c22 + +To avoid this issue, the IDL will now maintain (up to) 3 different +types of conditions for each DB table: +- new_cond: condition that has been set by the IDL client but has + not yet been sent to the server through monitor_cond_change. +- req_cond: condition that has been sent to the server but the reply + acknowledging the change hasn't been received yet. +- ack_cond: condition that has been acknowledged by the server. + +Whenever the IDL FSM is restarted (e.g., voluntary or involuntary +disconnect): +- if there is a known last_id txn-id the code ensures that new_cond + will contain the most recent condition set by the IDL client + (either req_cond if there was a request in flight, or new_cond + if the IDL client set a condition while the IDL was disconnected) +- if there is no known last_id txn-id the code ensures that ack_cond will + contain the most recent conditions set by the IDL client regardless + whether they were acked by the server or not. + +When monitor_cond_since/monitor_cond requests are sent they will +always include ack_cond and if new_cond is not NULL a follow up +monitor_cond_change will be generated afterwards. + +On the other hand ovsdb_idl_db_set_condition() will always modify new_cond. + +This ensures that updates of type "insert" that happened before the last +transaction known by the IDL but didn't match old monitor conditions are +sent upon reconnect if the monitor condition has changed to include them +in the meantime. + +Fixes: 403a6a0cb003 ("ovsdb-idl: Fast resync from server when connection reset.") +Signed-off-by: Dumitru Ceara +Acked-by: Han Zhou +Signed-off-by: Ilya Maximets +(cherry picked from

However, -there are some restrictions with the current implementation: - -* It is not possible to address the indiviual bits within the ct_mark or - ct_label. -* It is not possible to set these to the value of a register. Only - explicit integer setting can be used. - -With this change, ct_commit now can have arbitrary nested actions -inside. This makes it similar to how the "exec" option works in OVS's -ct() action. - -ct_commit now also sets a writeability scope so that ct_mark and -ct_label are the only symbols that are writeable. The positive side -effect is that ct_mark and ct_label are no longer writeable except for -inside ct_commit. - -In this commit, the only noticeable effect is that it allows for -slightly more expressive setting of ct_label.blocked. A future commit -will take further advantage of this. - -Signed-off-by: Mark Michelson ---- - include/ovn/actions.h | 9 +--- - include/ovn/expr.h | 1 + - lib/actions.c | 110 +++++++----------------------------------- - lib/logical-fields.c | 9 ++-- - northd/ovn-northd.c | 8 +-- - ovn-sb.xml | 11 +++-- - tests/ovn.at | 59 ++++++++++++---------- - 7 files changed, 72 insertions(+), 135 deletions(-) - -diff --git a/include/ovn/actions.h b/include/ovn/actions.h -index 34ba0d880..636cb4bc1 100644 ---- a/include/ovn/actions.h -+++ b/include/ovn/actions.h -@@ -57,7 +57,7 @@ struct ovn_extend_table;
