2 | The sync patches work is based on initial patches from | ||
3 | Krisztian <hidden@balabit.hu> and others and additional patches | ||
4 | from Jamal <hadi@cyberus.ca>. | ||
5 | |||
6 | The end goal for syncing is to be able to insert attributes + generate | ||
7 | events so that the an SA can be safely moved from one machine to another | ||
8 | for HA purposes. | ||
9 | The idea is to synchronize the SA so that the takeover machine can do | ||
10 | the processing of the SA as accurate as possible if it has access to it. | ||
11 | |||
12 | We already have the ability to generate SA add/del/upd events. | ||
13 | These patches add ability to sync and have accurate lifetime byte (to | ||
14 | ensure proper decay of SAs) and replay counters to avoid replay attacks | ||
15 | with as minimal loss at failover time. | ||
16 | This way a backup stays as closely uptodate as an active member. | ||
17 | |||
18 | Because the above items change for every packet the SA receives, | ||
19 | it is possible for a lot of the events to be generated. | ||
20 | For this reason, we also add a nagle-like algorithm to restrict | ||
21 | the events. i.e we are going to set thresholds to say "let me | ||
22 | know if the replay sequence threshold is reached or 10 secs have passed" | ||
23 | These thresholds are set system-wide via sysctls or can be updated | ||
24 | per SA. | ||
25 | |||
26 | The identified items that need to be synchronized are: | ||
27 | - the lifetime byte counter | ||
28 | note that: lifetime time limit is not important if you assume the failover | ||
29 | machine is known ahead of time since the decay of the time countdown | ||
30 | is not driven by packet arrival. | ||
31 | - the replay sequence for both inbound and outbound | ||
32 | |||
33 | 1) Message Structure | ||
34 | ---------------------- | ||
35 | |||
36 | nlmsghdr:aevent_id:optional-TLVs. | ||
37 | |||
38 | The netlink message types are: | ||
39 | |||
40 | XFRM_MSG_NEWAE and XFRM_MSG_GETAE. | ||
41 | |||
42 | A XFRM_MSG_GETAE does not have TLVs. | ||
43 | A XFRM_MSG_NEWAE will have at least two TLVs (as is | ||
44 | discussed further below). | ||
45 | |||
46 | aevent_id structure looks like: | ||
47 | |||
48 | struct xfrm_aevent_id { | ||
49 | struct xfrm_usersa_id sa_id; | ||
50 | __u32 flags; | ||
51 | }; | ||
52 | |||
53 | xfrm_usersa_id in this message layout identifies the SA. | ||
54 | |||
55 | flags are used to indicate different things. The possible | ||
56 | flags are: | ||
57 | XFRM_AE_RTHR=1, /* replay threshold*/ | ||
58 | XFRM_AE_RVAL=2, /* replay value */ | ||
59 | XFRM_AE_LVAL=4, /* lifetime value */ | ||
60 | XFRM_AE_ETHR=8, /* expiry timer threshold */ | ||
61 | XFRM_AE_CR=16, /* Event cause is replay update */ | ||
62 | XFRM_AE_CE=32, /* Event cause is timer expiry */ | ||
63 | XFRM_AE_CU=64, /* Event cause is policy update */ | ||
64 | |||
65 | How these flags are used is dependent on the direction of the | ||
66 | message (kernel<->user) as well the cause (config, query or event). | ||
67 | This is described below in the different messages. | ||
68 | |||
69 | The pid will be set appropriately in netlink to recognize direction | ||
70 | (0 to the kernel and pid = processid that created the event | ||
71 | when going from kernel to user space) | ||
72 | |||
73 | A program needs to subscribe to multicast group XFRMNLGRP_AEVENTS | ||
74 | to get notified of these events. | ||
75 | |||
76 | 2) TLVS reflect the different parameters: | ||
77 | ----------------------------------------- | ||
78 | |||
79 | a) byte value (XFRMA_LTIME_VAL) | ||
80 | This TLV carries the running/current counter for byte lifetime since | ||
81 | last event. | ||
82 | |||
83 | b)replay value (XFRMA_REPLAY_VAL) | ||
84 | This TLV carries the running/current counter for replay sequence since | ||
85 | last event. | ||
86 | |||
87 | c)replay threshold (XFRMA_REPLAY_THRESH) | ||
88 | This TLV carries the threshold being used by the kernel to trigger events | ||
89 | when the replay sequence is exceeded. | ||
90 | |||
91 | d) expiry timer (XFRMA_ETIMER_THRESH) | ||
92 | This is a timer value in milliseconds which is used as the nagle | ||
93 | value to rate limit the events. | ||
94 | |||
95 | 3) Default configurations for the parameters: | ||
96 | ---------------------------------------------- | ||
97 | |||
98 | By default these events should be turned off unless there is | ||
99 | at least one listener registered to listen to the multicast | ||
100 | group XFRMNLGRP_AEVENTS. | ||
101 | |||
102 | Programs installing SAs will need to specify the two thresholds, however, | ||
103 | in order to not change existing applications such as racoon | ||
104 | we also provide default threshold values for these different parameters | ||
105 | in case they are not specified. | ||
106 | |||
107 | the two sysctls/proc entries are: | ||
108 | a) /proc/sys/net/core/sysctl_xfrm_aevent_etime | ||
109 | used to provide default values for the XFRMA_ETIMER_THRESH in incremental | ||
110 | units of time of 100ms. The default is 10 (1 second) | ||
111 | |||
112 | b) /proc/sys/net/core/sysctl_xfrm_aevent_rseqth | ||
113 | used to provide default values for XFRMA_REPLAY_THRESH parameter | ||
114 | in incremental packet count. The default is two packets. | ||
115 | |||
116 | 4) Message types | ||
117 | ---------------- | ||
118 | |||
119 | a) XFRM_MSG_GETAE issued by user-->kernel. | ||
120 | XFRM_MSG_GETAE does not carry any TLVs. | ||
121 | The response is a XFRM_MSG_NEWAE which is formatted based on what | ||
122 | XFRM_MSG_GETAE queried for. | ||
123 | The response will always have XFRMA_LTIME_VAL and XFRMA_REPLAY_VAL TLVs. | ||
124 | *if XFRM_AE_RTHR flag is set, then XFRMA_REPLAY_THRESH is also retrieved | ||
125 | *if XFRM_AE_ETHR flag is set, then XFRMA_ETIMER_THRESH is also retrieved | ||
126 | |||
127 | b) XFRM_MSG_NEWAE is issued by either user space to configure | ||
128 | or kernel to announce events or respond to a XFRM_MSG_GETAE. | ||
129 | |||
130 | i) user --> kernel to configure a specific SA. | ||
131 | any of the values or threshold parameters can be updated by passing the | ||
132 | appropriate TLV. | ||
133 | A response is issued back to the sender in user space to indicate success | ||
134 | or failure. | ||
135 | In the case of success, additionally an event with | ||
136 | XFRM_MSG_NEWAE is also issued to any listeners as described in iii). | ||
137 | |||
138 | ii) kernel->user direction as a response to XFRM_MSG_GETAE | ||
139 | The response will always have XFRMA_LTIME_VAL and XFRMA_REPLAY_VAL TLVs. | ||
140 | The threshold TLVs will be included if explicitly requested in | ||
141 | the XFRM_MSG_GETAE message. | ||
142 | |||
143 | iii) kernel->user to report as event if someone sets any values or | ||
144 | thresholds for an SA using XFRM_MSG_NEWAE (as described in #i above). | ||
145 | In such a case XFRM_AE_CU flag is set to inform the user that | ||
146 | the change happened as a result of an update. | ||
147 | The message will always have XFRMA_LTIME_VAL and XFRMA_REPLAY_VAL TLVs. | ||
148 | |||
149 | iv) kernel->user to report event when replay threshold or a timeout | ||
150 | is exceeded. | ||
151 | In such a case either XFRM_AE_CR (replay exceeded) or XFRM_AE_CE (timeout | ||
152 | happened) is set to inform the user what happened. | ||
153 | Note the two flags are mutually exclusive. | ||
154 | The message will always have XFRMA_LTIME_VAL and XFRMA_REPLAY_VAL TLVs. | ||
155 | |||
156 | Exceptions to threshold settings | ||
157 | -------------------------------- | ||
158 | |||
159 | If you have an SA that is getting hit by traffic in bursts such that | ||
160 | there is a period where the timer threshold expires with no packets | ||
161 | seen, then an odd behavior is seen as follows: | ||
162 | The first packet arrival after a timer expiry will trigger a timeout | ||
163 | aevent; i.e we dont wait for a timeout period or a packet threshold | ||
164 | to be reached. This is done for simplicity and efficiency reasons. | ||
