scsi: be2iscsi: Fix a memleak in beiscsi_init_wrb_handle()

2023-12-13T17:18:13Z

[ Upstream commit 235f2b548d7f4ac5931d834f05d3f7f5166a2e72 ] When an error occurs in the for loop of beiscsi_init_wrb_handle(), we should free phwi_ctxt->be_wrbq before returning an error code to prevent potential memleak.

scsi: be2iscsi: Add length check when parsing nlattrs

2023-09-23T08:59:49Z

[ Upstream commit ee0268f230f66cb472df3424f380ea668da2749a ] beiscsi_iface_set_param() parses nlattr with nla_for_each_attr and assumes every attributes can be viewed as struct iscsi_iface_param_info. This is not true because there is no any nla_policy to validate the attributes passed from the upper function iscsi_set_iface_params(). Add the nla_len check before accessing the nlattr data and return EINVAL if the length check fails.

scsi: be2iscsi: Fix an error handling path in beiscsi_dev_probe()

scsi: iscsi: Fix shost->max_id use

2021-07-20T14:10:43Z

[ Upstream commit bdd4aad7ff92ae39c2e93c415bb6761cb8b584da ] The iscsi offload drivers are setting the shost->max_id to the max number of sessions they support. The problem is that max_id is not the max number of targets but the highest identifier the targets can have. To use it to limit the number of targets we need to set it to max sessions - 1, or we can end up with a session we might not have preallocated resources for.

scsi: be2iscsi: Revert "Fix a theoretical leak in beiscsi_create_eqs()"

2020-12-16T09:56:58Z

commit eeaf06af6f87e1dba371fbe42674e6f963220b9c upstream. My patch caused kernel Oopses and delays in boot. Revert it. The problem was that I moved the "mem->dma = paddr;" before the call to be_fill_queue(). But the first thing that the be_fill_queue() function does is memset the whole struct to zero which overwrites the assignment.

scsi: be2iscsi: Fix a theoretical leak in beiscsi_create_eqs()

2020-10-29T08:57:44Z

[ Upstream commit 38b2db564d9ab7797192ef15d7aade30633ceeae ] The be_fill_queue() function can only fail when "eq_vaddress" is NULL and since it's non-NULL here that means the function call can't fail. But imagine if it could, then in that situation we would want to store the "paddr" so that dma memory can be released.
