linux.git/drivers/net/mlx4/alloc.c, branch v2.6.24 Linux kernel source tree mlx4_core: Fix possible bad free in mlx4_buf_free() 2007-11-13T23:26:57+00:00 Ali Ayoub ali@mellanox.co.il 2007-11-13T23:26:57+00:00 3bba11e5c47dfc1d381a1ece26464fb7eea2d79c When mlx4_buf_free() is called from the error path of mlx4_buf_alloc(), it may be passed a buffer structure that does not have all pages filled in. Add a check for NULL to mlx4_buf_free() so we avoid passing NULL to dma_free_coherent() (which will crash).

IB/mlx4: Fix last allocated object tracking in bitmap allocator 2007-05-29T23:07:09+00:00 Roland Dreier rolandd@cisco.com 2007-05-29T23:07:09+00:00 a2cb4a98f243d01f2c8d5799c764bb96ffa66c44 Set last allocated object to the object after the one just allocated before ORing in the extra top bits. Also handle the case where this wraps around. Signed-off-by: Roland Dreier <rolandd@cisco.com>

IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adapters 2007-05-09T01:00:38+00:00 Roland Dreier rolandd@cisco.com 2007-05-09T01:00:38+00:00 225c7b1feef1b41170f7037a5b10a65cd8a42c54 Add an InfiniBand driver for Mellanox ConnectX adapters. Because these adapters can also be used as ethernet NICs and Fibre Channel HBAs, the driver is split into two modules: mlx4_core: Handles low-level things like device initialization and processing firmware commands. Also controls resource allocation so that the InfiniBand, ethernet and FC functions can share a device without stepping on each other. mlx4_ib: Handles InfiniBand-specific things; plugs into the InfiniBand midlayer.
