Subject: [PATCH] lib: define cmsg array with correct size in sendv and recvv
|
|
||||||
|
|
||||||
Philipp recently found a buffer overflow crash in his application when
|
|
||||||
using sctp_sendv().
|
|
||||||
|
|
||||||
In sctp_sendv(), the cmsg array is defined as one whole cmsg:
|
|
||||||
|
|
||||||
char _cmsg[CMSG_SPACE(sizeof(struct sctp_sendv_spa))]
|
|
||||||
|
|
||||||
while these options in struct sctp_sendv_spa are packed into msg_control
|
|
||||||
with multiple cmsgs, instead one whole cmsg.
|
|
||||||
|
|
||||||
So fix it by defining cmsg array with correct size:
|
|
||||||
|
|
||||||
char _cmsg[CMSG_SPACE(sizeof(struct sctp_sndinfo)) +
|
|
||||||
CMSG_SPACE(sizeof(struct sctp_prinfo)) +
|
|
||||||
CMSG_SPACE(sizeof(struct sctp_authinfo))];
|
|
||||||
|
|
||||||
Note that the similar fix is also needed in sctp_recvv().

+such as SCTP_RCVINFO, of the message stored in msg_iov to the socket endpoint.
|
|
||||||
+Each ancillary data item is preceded by a struct cmsghdr, see
|
|
||||||
+.B cmsg(3).
|
|
||||||

|
|
||||||
+of SCTP_SNDRCV. Note that data in the next message is not valid unless the current
|
|
||||||
+message is completely read, i.e., unless the MSG_EOR is set. SCTP_NXTINFO should be

|

+.SH EVENTS and NOTIFICATIONS
|
|
||||||
+An SCTP application may need to understand and process events and errors
|
|
||||||
+that happen on the SCTP stack. These events include network status changes,
|
|
||||||
+association startups, remote operational errors, and undeliverable messages.
|
|
||||||
+When a notification arrives, recvmsg() returns the notification in the
|
|
||||||
+application-supplied data buffer via msg_iov, and sets MSG_NOTIFICATION in
|
|
||||||
+msg_flags. See socket option SCTP_EVENT for the event enabling. The different
|
|
||||||
+events are listed below, and all these related macros and structures are
|
|
||||||
+defined in /usr/include/netinet/sctp.h.
|
|
||||||
+.TP
|
|
||||||
+.B SCTP_ASSOC_CHANGE
|
|
||||||
+Communication notifications inform the application that an SCTP
|
|
||||||
+association has either begun or ended. The notification format
|
|
||||||
+is struct sctp_assoc_change.
|
|
||||||
+.TP
|
|
||||||
+.B SCTP_PEER_ADDR_CHANGE
|
|
||||||
+When a destination address of a multi-homed peer encounters a state
|
|
||||||
+change, a peer address change event is sent. The notification format
|
|
||||||
+is struct sctp_paddr_change.
|
|
||||||
+.TP
|
|
||||||
+.B SCTP_REMOTE_ERROR
|
|
||||||
+A remote peer may send an Operation Error message to its peer. This
|
|
||||||
+message indicates a variety of error conditions on an association.
|
|
||||||
+The notification format is struct sctp_remote_error.
|
|
||||||
+.TP
|
|
||||||
+.B SCTP_SEND_FAILED
|
|
||||||
+If SCTP cannot deliver a message, it can return back the message as a
|
|
||||||
+notification if the SCTP_SEND_FAILED event is enabled. The notification
|
|
||||||
+format is struct sctp_send_failed. Please note that this notification
|
|
||||||
+is deprecated. Use SCTP_SEND_FAILED_EVENT instead.
|
|
||||||
+.TP
|
|
||||||
+.B SCTP_SHUTDOWN_EVENT
|
|
||||||
+When a peer sends a SHUTDOWN, SCTP delivers this notification to inform
|
|
||||||
+the application that it should cease sending data. The notification
|
|
||||||
+format is struct sctp_shutdown_event.
|
|
||||||
+.TP
|
|
||||||
+.B SCTP_ADAPTATION_INDICATION
|
|
||||||
+When a peer sends an Adaptation Layer Indication parameter, SCTP delivers
|
|
||||||
+this notification to inform the application about the peer's adaptation
|
|
||||||
+layer indication. The notification format is struct sctp_adaptation_event.
|
|
||||||
+.TP
|
|
||||||
+.B SCTP_PARTIAL_DELIVERY_EVENT
|
|
||||||
+When a receiver is engaged in a partial delivery of a message, this
|
|
||||||
+notification will be used to indicate various events. The notification
|
|
||||||
+format is struct sctp_pdapi_event.
|
|
||||||
+.TP
|
|
||||||
+.B SCTP_AUTHENTICATION_EVENT
|
|
||||||
+This is used to report different events relating to the use of the
|
|
||||||
+extension to authenticate SCTP messages. The notification format is
|
|
||||||
+struct sctp_authkey_event.
|
|
||||||
+.TP
|
|
||||||
+.B SCTP_SENDER_DRY_EVENT
|
|
||||||
+When the SCTP stack has no more user data to send or retransmit, this
|
|
||||||
+notification is given to the user. Also, at the time when a user app
|
|
||||||
+subscribes to this event, if there is no data to be sent or retransmit,
|
|
||||||
+the stack will immediately send up this notification. The notification
|
|
||||||
+format is struct sctp_sender_dry_event.
|
|
||||||
+.TP
|
|
||||||
+.B SCTP_SEND_FAILED_EVENT
|
|
||||||
+If SCTP cannot deliver a message, it can return back the message as a
|
|
||||||
+notification if the SCTP_SEND_FAILED_EVENT event is enabled. The
|
|
||||||
+notification format is struct sctp_send_failed_event.

+the application to get or set the delayed SACK time, in milliseconds, and

+This option allows the setting, on an association basis, of a default

+context that will be received on reading messages from the peer.
|
|
||||||
+This is especially helpful for an application when using one-to-many

+.B SCTP_PARTIAL_DELIVERY_POINT
|
|
||||||
+This option will set or get the SCTP partial delivery point. This
|
|
||||||
+point is the size of a message where the partial delivery API will be
|
|
||||||
+invoked to help free up rwnd space for the peer. Setting this to a
|
|
||||||
+lower value will cause partial deliveries to happen more often. This

Subject: [PATCH 4/6] man: improve the description in SOCKET OPTIONS in sctp.7
|
|
||||||
|
|
||||||
SCTP_{FUTURE|CURRENT|ALL}_ASSOC have been introduced for some options to
|
|
||||||
make set/get more effectively, we should mention it in the description
|
|
||||||
of these options. Also, it's better to give users more information like:
|
|
||||||
the structure it uses as parameter, the default value, the dependence on
|
|
||||||
other options if any, write or read permissions etc.
|
|

Subject: [PATCH 4/4] sctp_darn: replace use of deprecated gethostbyname with

|
|
||||||
|
|
||||||
This patch is to replace use of deprecated gethostbyname with
|
|
||||||
getaddrinfo in the file src/apps/sctp_darn.c.
|
|
||||||
|
|
||||||
Note that different from sctp_test, sctp_darn prefers v4 address
|
|
||||||
to v6 address when getting addrinfo from hostname. To keep the
|
|
||||||
compatibility, we don't change it.

Subject: [PATCH] sctp_test: check strdup return in append_addr
|
|
||||||
|
|
||||||
strdup() may return NULL in append_addr(), and we should do the
|
|
||||||
check for its return value before operating it.
