Gustav Wiklander 166761d2aa spi: Fix memory leak on splited transfers ... [ Upstream commit b59a7ca15464c78ea1ba3b280cfc5ac5ece11ade ] In the prepare_message callback the bus driver has the opportunity to split a transfer into smaller chunks. spi_map_msg is done after prepare_message. Function spi_res_release releases the splited transfers in the message. Therefore spi_res_release should be called after spi_map_msg. The previous try at this was commit c9ba7a16d0f1 which released the splited transfers after spi_finalize_current_message had been called. This introduced a race since the message struct could be out of scope because the spi_sync call got completed. Fixes this leak on spi bus driver spi-bcm2835.c when transfer size is greater than 65532: Kmemleak: sg_alloc_table+0x28/0xc8 spi_map_buf+0xa4/0x300 __spi_pump_messages+0x370/0x748 __spi_sync+0x1d4/0x270 spi_sync+0x34/0x58 spi_test_execute_msg+0x60/0x340 [spi_loopback_test] spi_test_run_iter+0x548/0x578 [spi_loopback_test] spi_test_run_test+0x94/0x140 [spi_loopback_test] spi_test_run_tests+0x150/0x180 [spi_loopback_test] spi_loopback_test_probe+0x50/0xd0 [spi_loopback_test] spi_drv_probe+0x84/0xe0 Signed-off-by: Gustav Wiklander <gustavwi@axis.com> Link: https://lore.kernel.org/r/20200908151129.15915-1-gustav.wiklander@axis.com Signed-off-by: Mark Brown <broonie@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>		2021-03-16 16:36:15 +08:00
