staging: r8822be: Fix RTL8822be can't find any wireless AP

2018-07-17T09:48:24+00:00

commit d59d2f9995d28974877750f429e821324bd603c7 upstream. RTL8822be can't bring up properly on ASUS X530UN, and dmesg says: [ 8.591333] r8822be: module is from the staging directory, the quality is unknown, you have been warned.

staging: rtl8723bs: Prevent an underflow in rtw_check_beacon_data().

2018-07-17T09:48:24+00:00

commit 920c92448839bd4f8eb87a92b08cad56d449caff upstream. Dan Carpenter reported an integer underflow issue in the rtl8188eu driver. This is also needed for the length (signed integer) in rtl8723bs, as it is later converted to an unsigned integer and used in a memcpy operation. Original issue is at https://patchwork.kernel.org/patch/9796371/ Reported-by: Dan Carpenter Signed-off-by: Murray McAllister Cc: stable Signed-off-by: Greg Kroah-Hartman

commit 1376b0a2160319125c3a2822e8c09bd283cd8141 upstream. There is a '>' vs '<' typo so this loop is a no-op. Fixes: d35dcc89fc93 ("staging: comedi: quatech_daqp_cs: fix daqp_ao_insn_write()") Signed-off-by: Dan Carpenter Reviewed-by: Ian Abbott Signed-off-by: Greg Kroah-Hartman

staging: android: ion: Return an ERR_PTR in ion_map_kernel

2018-07-08T13:32:17+00:00

commit 0a2bc00341dcfcc793c0dbf4f8d43adf60458b05 upstream. The expected return value from ion_map_kernel is an ERR_PTR. The error path for a vmalloc failure currently just returns NULL, triggering a warning in ion_buffer_kmap_get. Encode the vmalloc failure as an ERR_PTR.

staging: android: ion: Switch to pr_warn_once in ion_buffer_destroy

2018-06-16T07:18:20+00:00

commit 45ad559a29629cb1c64ee636563c69b71524f077 upstream. Syzbot reported yet another warning with Ion: WARNING: CPU: 0 PID: 1467 at drivers/staging/android/ion/ion.c:122 ion_buffer_destroy+0xd4/0x190 drivers/staging/android/ion/ion.c:122 Kernel panic - not syncing: panic_on_warn set ... This is catching that a buffer was freed with an existing kernel mapping still present. This can be easily be triggered from userspace by calling DMA_BUF_SYNC_START without calling DMA_BUF_SYNC_END. Switch to a single pr_warn_once to indicate the error without being disruptive.

Pull rdma fixes from Jason Gunthorpe: "Just three small last minute regressions that were found in the last week. The Broadcom fix is a bit big for rc7, but since it is fixing driver crash regressions that were merged via netdev into rc1, I am sending it. - bnxt netdev changes merged this cycle caused the bnxt RDMA driver to crash under certain situations - Arnd found (several, unfortunately) kconfig problems with the patches adding INFINIBAND_ADDR_TRANS. Reverting this last part, will fix it more fully outside -rc. - Subtle change in error code for a uapi function caused breakage in userspace.

IB: Revert "remove redundant INFINIBAND kconfig dependencies"

2018-05-28T16:40:16+00:00

Several subsystems depend on INFINIBAND_ADDR_TRANS, which in turn depends on INFINIBAND. However, when with CONFIG_INIFIBAND=m, this leads to a link error when another driver using it is built-in. The INFINIBAND_ADDR_TRANS dependency is insufficient here as this is a 'bool' symbol that does not force anything to be a module in turn. fs/cifs/smbdirect.o: In function `smbd_disconnect_rdma_work': smbdirect.c:(.text+0x1e4): undefined reference to `rdma_disconnect' net/9p/trans_rdma.o: In function `rdma_request': trans_rdma.c:(.text+0x7bc): undefined reference to `rdma_disconnect' net/9p/trans_rdma.o: In function `rdma_destroy_trans': trans_rdma.c:(.text+0x830): undefined reference to `ib_destroy_qp' trans_rdma.c:(.text+0x858): undefined reference to `ib_dealloc_pd' Fixes: 9533b292a7ac ("IB: remove redundant INFINIBAND kconfig dependencies") Signed-off-by: Arnd Bergmann Acked-by: Greg Thelen Signed-off-by: Jason Gunthorpe
