From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx> Hi all, The following patch series contains a number of target SPC/SBC related emulation fixes that address failures occurring while using Ronnie Sahlberg's excellent libiscsi test suite. The first two are the important ones. Patch #1 adds a missing end-of-device sanity check for WRITE_SAME emulation, that Bart had reported earlier. Patch #2 fixes a case where the existing end-of-device check did not take into account the potential of LBA + sector wrapping overflowing sector_t. The remaining patches address other minor test failures. This includes failing I/O + WRITE_SAME ops when PROTECT bit is set, if the backend device is not configured to support protection information. Also included are sanity checks for DPO/FUA, WRITE_SAME w/ UNMAP=1 and UNMAP that will fail the command if the associated feature bits are not being advertised by the backend device via existing device attributes. Please review. Thank you, --nab Nicholas Bellinger (8): target: Add missing WRITE_SAME end-of-device sanity check target: Check for LBA + sectors wrap-around in sbc_parse_cdb target: Fail I/O with PROTECT bit when protection is unsupported target: Perform PROTECT sanity checks for WRITE_SAME target: Add sanity checks for DPO/FUA bit usage target: Fail WRITE_SAME w/ UNMAP=1 when emulate_tpws=0 target: Fail UNMAP when emulate_tpu=0 target: Set LBPWS10 bit in Logical Block Provisioning EVPD drivers/target/target_core_file.c | 5 ++ drivers/target/target_core_iblock.c | 5 ++ drivers/target/target_core_sbc.c | 140 ++++++++++++++++++++++++++++-------- drivers/target/target_core_spc.c | 2 +- 4 files changed, 121 insertions(+), 31 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
