[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>

This reverts commit b23270416da409bd4e637a5acbe31a1126235fb6 which is
commit f6e80abeab928b7c47cc1fbf53df13b4398a2bec.

Michal writes:
	Mainline commit f6e80abe was introduced in v3.7-rc2 as a
	follow-up fix to commit

	  edfee033  sctp: check src addr when processing SACK to update transport state

	(from v3.7-rc1) which changed the interpretation of third
	argument to sctp_cmd_process_sack() and sctp_outq_sack(). But as
	commit edfee033 has never been backported to stable branches,
	backport of commit f6e80abe actually breaks the code rather than
	fixing it.
