scsi: firewire: sbp-target: Fix overflow in sbp_make_tpg()

2026-02-06T15:48:23+00:00

[ Upstream commit b2d6b1d443009ed4da2d69f5423ab38e5780505a ] The code in sbp_make_tpg() limits "tpgt" to UINT_MAX but the data type of "tpg->tport_tpgt" is u16. This causes a type truncation issue. When a user creates a TPG via configfs mkdir, for example: mkdir /sys/kernel/config/target/sbp//tpgt_70000 The value 70000 passes the "tpgt > UINT_MAX" check since 70000 is far less than 4294967295. However, when assigned to the u16 field tpg->tport_tpgt, the value is silently truncated to 4464 (70000 & 0xFFFF). This causes the value the user specified to differ from what is actually stored, leading to confusion and potential unexpected behavior. Fix this by changing the type of "tpgt" to u16 and using kstrtou16() which will properly reject values outside the u16 range.

The se_cmd scsi_asc and scsi_ascq members are only used for tracking ALUA SCSI sense detail between target_core_alua and translate_sense_reason(), so they're effectively always zero here.

scsi: target: sbp_target: Remove redundant assignment to pg_size

2021-05-15T03:09:24+00:00

Variable pg_size is set to '0x100 << pg_size', but this value is never read and it is not used later on. Hence it is a redundant assignment and can be removed. Clean up the following clang-analyzer warning: drivers/target/sbp/sbp_target.c:1264:3: warning: Value stored to 'pg_size' is never read [clang-analyzer-deadcode.DeadStores].

scsi: target: sbp_target: Convert to new submission API

2021-03-04T22:37:01+00:00

target_submit_cmd() is now only for simple drivers that do their own sync during shutdown and do not use target_stop_session(). It will never return a failure, so we can remove that code from the driver.
