| Summary | 0000356: 28 Bits for the large block size field aren't enough. | ||||
| Description | On Linux, using smalloc and pthreads means that core memory is allocated using malloc(). With a MIN_ALLOCED of 128 MByte, the malloc() sequence is malloc(98460) -> 08236208 malloc(134217948) ->afd0b008 malloc(67109084) -> abcf8008 The driver, when trying to build the bridge block from 0x08236208 to 0xafd0b008 exceeds the range limit for the M_SIZE block. Short term solution: don't use this combination. | ||||

|
Possible solution: introduce a new flag 'M_HUGE': if it is set, it means that the size of the block is given in multiples of 64 Bytes (= 16 words). This allows to store blocksizes of up to 32 Bit in just 26 Bits (which would work fine for both smalloc and slaballoc). The limit would be blocksizes of 64KByte. |

|
Corrected in 3.3.670 with the introduction of an additional size field; checked for and rejected in 3.2. |
