Paolo Bonzini recently did some work in target-core to gracefully handle zero-length allocations for pSCSI backends (virtual backends like IBLOCK+ FILEIO where fixed for v3.3.x IIRC). This series went into v3.6-rc6 recently: The main ones in question from target-pending/master are: 6abbdf383 target: go through normal processing for zero-length REQUEST_SENSE 32a8811ff target: support zero allocation length in REQUEST SENSE 3717ef0c6 target: support zero-size allocation lengths in transport_kmap_data_sg 9b16b9edb target: fail REPORT LUNS with less than 16 bytes of payload 0d7f1299c target: report too-small parameter lists everywhere 306c11b28 target: go through normal processing for zero-length PSCSI commands d5829eac5 target: fix use-after-free with PSCSI sense data 27a270991 target: simplify code around transport_get_sense_data Just to verify, which type of target backend driver is this with..? --nab -- 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
