Patent number: 8850273Abstract: An apparatus for monitoring changes to a block of data is disclosed. A first hardware watchpoint is set to monitor changes to the block of data at a current location of the block of data in memory and a second hardware watchpoint is set to monitor changes at a selected location in the memory where a reference to the block of data is located. Responsive to the second hardware watchpoint being triggered by a change at the selected location where the reference to the block of data is located, a new location of the block of data in the memory is identified based on the change that triggered the second hardware watchpoint. Subsequent to identifying the new location of the block of data, the first hardware watchpoint is reset to monitor changes to the block of data at the new location of the block of data.Type: GrantFiled: November 16, 2013Date of Patent: September 30, 2014Assignee: International Business Machines CorporationInventors: Joshi Chandran, Shajith Chandran, Manish Kulshreshtha, Dilip K.

Patent number: 8843790Abstract: A method and apparatus for monitoring changes to a block of data is disclosed. A computer sets a first hardware watchpoint to monitor changes to the block of data at a current location of the block of data in memory and a second hardware watchpoint to monitor changes at a selected location in the memory where a reference to the block of data is located. Responsive to the second hardware watchpoint being triggered by a change at the selected location where the reference to the block of data is located, the computer identifies a new location of the block of data in the memory based on the change that triggered the second hardware watchpoint. Subsequent to identifying the new location of the block of data, the computer then resets the first hardware watchpoint to monitor changes to the block of data at the new location of the block of data.Type: GrantFiled: July 27, 2012Date of Patent: September 23, 2014Assignee: International Business Machines CorporationInventors: Joshi Chandran, Shajith Chandran, Manish Kulshreshtha, Dilip K.

Patent number: 8793542Abstract: Provided are techniques for receiving a packet transmitted in conjunction with a security association associated with Internet Protocol Security (IPSec); determining, based upon the security Association that the packet is faulty; incrementing a count corresponding to previous faulty packets received; determining that the count exceeds a threshold; and disabling IPSec accelerator hardware in response to the determining that the count exceeds the threshold.Type: GrantFiled: April 11, 2013Date of Patent: July 29, 2014Assignee: International Business Machines CorporationInventors: Kokil K. Deuri, Vishal R. Mansur, Arpana Prashanth, Dilip K. Singh

Patent number: 8683267Abstract: An approach to providing multiple concurrently executing debugging sessions for a currently executing operating system. The approach involves providing one first debugging session for debugging the currently executing operating system. The first debugging session has read access and write access to the data of the currently executing operating system. The approach also involves providing one or more second debugging sessions for the currently executing operating system. Each of the second debugging sessions has read-only access to the data of the currently executing operating system. The second debugging sessions run simultaneously with the first debugging session if the second debugging sessions are started while the first debugging session is active. As a result, multiple users can simultaneously debug the currently executing operating system. A lock may be used to ensure that only the first debugging session has write access to the data.Type: GrantFiled: June 7, 2011Date of Patent: March 25, 2014Assignee: International Business Machines CorporationInventors: Shajith Chandran, Manish Kulshreshtha, Anil K. Singh, Dilip K. Singh
