From c536277e0db1ad2e9fbb9dfd940c3565a14d9c52 Mon Sep 17 00:00:00 2001 From: Bernard Metzler Date: Thu, 22 Aug 2019 19:37:38 +0200 Subject: RDMA/siw: Fix 64/32bit pointer inconsistency Fixes improper casting between addresses and unsigned types. Changes siw_pbl_get_buffer() function to return appropriate dma_addr_t, and not u64. Also fixes debug prints. Now any potentially kernel private pointers are printed formatted as '%pK', to allow keeping that information secret. Fixes: d941bfe500be ("RDMA/siw: Change CQ flags from 64->32 bits") Fixes: b0fff7317bb4 ("rdma/siw: completion queue methods") Fixes: 8b6a361b8c48 ("rdma/siw: receive path") Fixes: b9be6f18cf9e ("rdma/siw: transmit path") Fixes: f29dd55b0236 ("rdma/siw: queue pair methods") Fixes: 2251334dcac9 ("rdma/siw: application buffer management") Fixes: 303ae1cdfdf7 ("rdma/siw: application interface") Fixes: 6c52fdc244b5 ("rdma/siw: connection management") Fixes: a531975279f3 ("rdma/siw: main include file") Reported-by: Geert Uytterhoeven Reported-by: Jason Gunthorpe Reported-by: Leon Romanovsky Signed-off-by: Bernard Metzler Link: https://lore.kernel.org/r/20190822173738.26817-1-bmt@zurich.ibm.com Signed-off-by: Doug Ledford --- drivers/infiniband/sw/siw/siw.h | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'drivers/infiniband/sw/siw/siw.h') diff --git a/drivers/infiniband/sw/siw/siw.h b/drivers/infiniband/sw/siw/siw.h index 77b1aabf6ff3..dba4535494ab 100644 --- a/drivers/infiniband/sw/siw/siw.h +++ b/drivers/infiniband/sw/siw/siw.h @@ -138,9 +138,9 @@ struct siw_umem { }; struct siw_pble { - u64 addr; /* Address of assigned user buffer */ - u64 size; /* Size of this entry */ - u64 pbl_off; /* Total offset from start of PBL */ + dma_addr_t addr; /* Address of assigned buffer */ + unsigned int size; /* Size of this entry */ + unsigned long pbl_off; /* Total offset from start of PBL */ }; struct siw_pbl { @@ -734,7 +734,7 @@ static inline void siw_crc_skb(struct siw_rx_stream *srx, unsigned int len) "MEM[0x%08x] %s: " fmt, mem->stag, __func__, ##__VA_ARGS__) #define siw_dbg_cep(cep, fmt, ...) \ - ibdev_dbg(&cep->sdev->base_dev, "CEP[0x%p] %s: " fmt, \ + ibdev_dbg(&cep->sdev->base_dev, "CEP[0x%pK] %s: " fmt, \ cep, __func__, ##__VA_ARGS__) void siw_cq_flush(struct siw_cq *cq); -- cgit v1.2.3
