Make sure that userspace passes in enough data when sending a MAD. We always copy at least sizeof (struct ib_user_mad) + IB_MGMT_RMPP_HDR bytes from userspace, so anything less is definitely invalid. Also, if the length is less than this limit, it's possible for the second copy_from_user() to get a negative length and trigger a BUG(). Signed-off-by: Roland Dreier <rolandd@cisco.com>

Jeff Garzik pointed me to his code to see how to remove a disk from the system _properly_. Well, here it is... Every place we remove disks we are now testing before calling del_gendisk or blk_cleanup_queue and then call put_disk.

Applications using CCISS_BIG_PASSTHRU complained that the data written was zeros. The problem is that the buffer is being cleared after the user copy, unless the user copy has failed... Correct that logic. Signed-off-by: Mike Miller <mike.miller@hp.com> Signed-off-by: Jens Axboe <axboe@suse.de>

This patch fixes a bug that breaks hpacucli, a command line interface for the HP Array Config Utility. Without this fix the utility will not detect any controllers in the system. I thought I had already fixed this, but I guess not. Thanks to all who reported the issue. Please consider this this inclusion.

ipw2100: Fix 'Driver using old /proc/net/wireless...' message Wireless extensions moved the get_wireless_stats handler from being in net_device into wireless_handler.

hermas_bap_pread, hermes_bap_pwrite, and hermes_bap_pwrite_pad all have a parameter "len" that is declared unsigned, but checked for a value less than zero. Auditing the callers, it is possible for len to be passed a negative value, so len should be an int. Thanks to LinuxICC (http://linuxicc.sf.net) Signed-off-by: Gabriel A.

For the four versions of hardware that we (currently) support microcode download on, the default configuration of our receive interrupt mitigation microcode was too aggressive, and caused unnecessary delays when pinging, and low(er) throughput on single connection latency sensitive performance tests. This code adds microcode support, and sets the defaults to more reasonable settings. It also explains the functionality in the code in more detail. Compile and load tested, shows expected behavior for slight delay of ping packets (1-2ms) when ucode is loaded, and decent interrupt moderation for small packets, while maintaining good throughput.

sil24_error_intr logs all error interrupts. ATAPI devices generates many harmless errors which can be ignored and all serious ones are reported via sense data by SCSI layer.

There seems to be no way to obtain device signature from sil24 after SATA phy reset and SRST is needed anyway for later port multiplier suppport. This patch converts sil24_phy_reset to use SRST instaed. Signed-off-by: Tejun Heo <htejun@gmail.com> -- Jeff, I didn't remove the 10ms sleep just to be on the safe side. I think we can live with 10ms sleep on SRST. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

When an error condition is raised by device via D2H FIS or SDB. sil24 controller should be restarted by setting PORT_CS_INIT and waiting until PORT_CS_RDY is asserted instead of resetting the controller. This patch implements sil24_restart_controller for those cases. This patch also makes sure that PORT_CS_RDY is asserted on sil24_reset_controller completion. Signed-off-by: Tejun Heo <htejun@gmail.com> -- Jeff, delay is reduced to 1us and cnt increased to 10k. My sil3124 turns on PORT_CS_RDY on the second iteration even without any delay. I think 10k * 1us should be more than enough. I tried to convert both restart and reset to use msleep's with work queue, but if we do that, host_set lock should be released after initiating restart or reset, leading to race condition among reset/restart, other interrupts and timeout. Implementing synchronization among those in low-level driver doesn't seem right. Well, reduced timeout should work for the time being. Thanks. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

The smc91x driver relies upon register bank 2 being selected whenever the interrupt handler is called. This isn't always so, especially if we have a link change event during PHY configuration. This results in register bank 0 being selected when the interrupt handler is called, causing the wrong registers to be read for the IRQ mask and status. In turn, this causes us to spin with a permanently asserted IRQ. The patch ensures that smc_phy_configure always exits with register bank 2 selected.
