2016-02-01trafgen: parser: Add TCP header generation functionTobias Klauser1-0/+19
Add a function 'tcp()' to generate TCP headers from the trafgen configuration language. Fields supported: sp|sport TCP source port (default 0) dp|dport TCP destination port (default 0) seq Sequence number (default: 0) aseq|ackseq Acknowledgement number (default 0) doff|hlen Header length/data offset (default: 5) cwr Congestion Window Reduced flag (default: 0) ece|ecn ECN-Echo flag (default: 0) urg Urgent flag (default: 0) ack Acknowledgement flag (default: 0) psh Push flag (default: 0) rst Reset flag (default: 0) syn Synchronize flag (default: 0) fin Finish flag (default: 0) win|window Receive window size (default: 0) csum Checksum field (calculated automatically) urgptr Urgent pointer (default: 0) Example (SYN on port 80/http): { tcp(dport=80, syn, window=5840) } Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2016-01-29trafgen: l4: Add UDP header generation logicVadim Kochan1-0/+13
Add trafgen_l4.c module with generation UDP header fields. UDP protocol generation logic automaticaly sets the protocol field of the lower level protocol to IPPROTO_UDP by default (if it is IPv4). Also checksum & length are calculated and set if it is not given by the user. Signed-off-by: Vadim Kochan <vadim4j@gmail.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

x86/mce: Make timer handling more robust
Erik reported that on a preproduction hardware a CMCI storm triggers the BUG_ON in add_timer_on(). The reason is that the per CPU MCE timer is started by the CMCI logic before the MCE CPU hotplug callback starts the timer with add_timer_on(). So the timer is already queued which triggers the BUG. Using add_timer_on() is pretty pointless in this code because the timer is strictlty per CPU, initialized as pinned and all operations which arm the timer happen on the CPU to which the timer belongs. Simplify the whole machinery by using mod_timer() instead of add_timer_on() which avoids the problem because mod_timer() can handle already queued timers. Use __start_timer() everywhere so the earliest armed expiry time is preserved.
