  • dc80bce266 Fixed a race between initiator and target in the algorithm for computing the REQUEST LIMIT DELTA value sent in responses towards the initiator that could cause the initiators req_lim value temporarily to exceed 128 (SRPT_RQ_SIZE). While harmless, this caused messages like "ib_srpt: ***ERROR***: req_lim = -1 < 0" to appear in the target kernel log. Bart Van Assche 2010-07-24 08:35:28 +00:00

  • 5737910fb4 Put in a clearer work-around for the problem with the size of the max_cmd_size field. The size changed at 2.6.26 from unsigned char to unsigned short. Richard Sharpe 2010-07-22 09:40:14 +00:00
  • 380d63a33e Updated performance measurements. Bart Van Assche 2010-07-22 08:32:50 +00:00

  • 6f8dfe947f - Handle Default and Default_ groups. Default_X groups will not be configured if the associated target X has not been pre-configured. - Misc. fixes. Mark Buechler 2010-07-21 17:24:48 +00:00
  • 8668b22ae8 Set max_cmd_len correctly depending on the size of the field. In earlier versions of Linux it was an unsigned char, and a value of 260 means 4 after a compiler warning. Added a comment to describe what is going on as well. Since this is done very infequently it should not cause performance problems and means that it will not silently fail to work if people try to use it on kernels earlier than 2.6.26. If I figure out what kernel version the change was made in we could use an ifdef. Richard Sharpe 2010-07-21 16:08:34 +00:00

  • 5ded0b7660 Changes: - Implemented a workaround for a race between ib_destroy_cq() and the IB completion handlers. This race could trigger a kernel crash or kernel lockup when unloading the ib_srpt module while I/O was ongoing or by performing a relogin from an SRP initiator while I/O was ongoing. - Moved the code for handling IB completions in single-threaded mode to separate functions.
