2019-03-29staging: vt6655: Remove vif check from vnt_interruptMalcolm Priestley1-2/+1
A check for vif is made in vnt_interrupt_work. There is a small chance of leaving interrupt disabled while vif is NULL and the work hasn't been scheduled.

After commit 419d6efc50e9, kernel cannot be crashed in the namei path. However, corrupted nameoff can do harm in the process of readdir for scenerios without dm-verity as well. Fix it now.

2019-03-26staging: octeon-ethernet: fix incorrect PHY modeAaro Koskinen3-7/+39
When connecting PHY, we set the mode to PHY_INTERFACE_MODE_GMII which is not always correct. Specifically on boards where RGMII_RXID is needed networking now longer works with at803x after commit 6d4cd041f0af ("net: phy: at803x: disable delay only for RGMII mode"). Fix by passing the correct mode. Tested on EdgeRouter Lite (RGMII_RXID, at803x PHY) and D-Link DSR-500N (RGMII, broadcom PHY).

2019-03-26staging: erofs: fix error handling when failed to read compresssed dataGao Xiang1-13/+28
Complete read error handling paths for all three kinds of compressed pages: 1) For cache-managed pages, PG_uptodate will be checked since read_endio will unlock and SetPageUptodate for these pages; 2) For inplaced pages, read_endio cannot SetPageUptodate directly since it should be used to mark the final decompressed data, PG_error will be set with page locked for IO error instead; 3) For staging pages, PG_error is used, which is similar to what we do for inplaced pages.

2019-03-26staging: vt6655: Fix interrupt race condition on device start up.Malcolm Priestley1-4/+4
It appears on some slower systems that the driver can find its way out of the workqueue while the interrupt is disabled by continuous polling by it. Move MACvIntEnable to vnt_interrupt_work so that it is always enabled on all routes out of vnt_interrupt_process. Move MACvIntDisable so that the device doesn't keep polling the system while the workqueue is being processed.

2019-03-21staging: rtl8712: uninitialized memory in read_bbreg_hdl()Dan Carpenter2-10/+2
Colin King reported a bug in read_bbreg_hdl(): memcpy(pcmd->rsp, (u8 *)&val, pcmd->rspsz); The problem is that "val" is uninitialized. This code is obviously not useful, but so far as I can tell "pcmd->cmdcode" is never GEN_CMD_CODE(_Read_BBREG) so it's not harmful either. For now the easiest fix is to just call r8712_free_cmd_obj() and return.

2019-03-18staging: comedi: ni_mio_common: Fix divide-by-zero for DIO cmdtestIan Abbott3-7/+38
`ni_cdio_cmdtest()` validates Comedi asynchronous commands for the DIO subdevice (subdevice 2) of supported National Instruments M-series cards. It is called when handling the `COMEDI_CMD` and `COMEDI_CMDTEST` ioctls for this subdevice. There are two causes for a possible divide-by-zero error when validating that the `stop_arg` member of the passed-in command is not too large. The first cause for the divide-by-zero is that calls to `comedi_bytes_per_scan()` are only valid once the command has been copied to `s->async->cmd`, but that copy is only done for the `COMEDI_CMD` ioctl. For the `COMEDI_CMDTEST` ioctl, it will use whatever was left there by the previous `COMEDI_CMD` ioctl, if any. (This is very likely, as it is usual for the application to use `COMEDI_CMDTEST` before `COMEDI_CMD`.) If there has been no previous, valid `COMEDI_CMD` for this subdevice, then `comedi_bytes_per_scan()` will return 0, so the subsequent division in `ni_cdio_cmdtest()` of `s->async->prealloc_bufsz / comedi_bytes_per_scan(s)` will be a divide-by-zero error. To fix this error, call a new function `comedi_bytes_per_scan_cmd(s, cmd)`, based on the existing `comedi_bytes_per_scan(s)` but using a specified `struct comedi_cmd` for its calculations. (Also refactor `comedi_bytes_per_scan()` to call the new function.) Once the first cause for the divide-by-zero has been fixed, the second cause is that `comedi_bytes_per_scan_cmd()` can legitimately return 0 if the `scan_end_arg` member of the `struct comedi_cmd` being tested is 0. Fix it by only performing the division (and validating that `stop_arg` is no more than the maximum value) if `comedi_bytes_per_scan_cmd()` returns a non-zero value.

2019-03-18staging: mt7621-dts: update ethernet settings.NeilBrown2-19/+83
The ethernet in mt7621 is now supported by drivers/net/ethernet/mediatek/ which provides support for the integrated switch through DSA. This requires some devicetree changes, and particularly allows a board dts to identify which switch ports are present. The second CPU interface - gmac1 - doesn't work yet, so the device tree information may not be correct. The phy (which is present on the gnubee-pc2) can negotiate and report connection speed etc, but no traffic flows. The gnubee-pc1 has two network ports which are 'black' and 'blue'. There are connected to switch ports 0 and 4 respectively. Signed-off-by: NeilBrown <neil@brown.name> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2019-03-04get rid of legacy 'get_ds()' functionLinus Torvalds1-2/+2
Every in-kernel use of this function defined it to KERNEL_DS (either as an actual define, or as an inline function). It's an entirely historical artifact, and long long long ago used to actually read the segment selector valueof '%ds' on x86. Which in the kernel is always KERNEL_DS. Inspired by a patch from Jann Horn that just did this for a very small subset of users (the ones in fs/), along with Al who suggested a script. I then just took it to the logical extreme and removed all the remaining gunk. Roughly scripted with git grep -l '(get_ds())' -- :^tools/ | xargs sed -i 's/(get_ds())/(KERNEL_DS)/' git grep -lw 'get_ds' -- :^tools/ | xargs sed -i '/^#define get_ds()/d' plus manual fixups to remove a few unusual usage patterns, the couple of inline function cases and to fix up a comment that had become stale. The 'get_ds()' function remains in an x86 kvm selftest, since in user space it actually does something relevant.

2019-02-27staging: erofs: fix mis-acted TAIL merging behaviorGao Xiang1-25/+45
EROFS has an optimized path called TAIL merging, which is designed to merge multiple reads and the corresponding decompressions into one if these requests read continuous pages almost at the same time. In general, it behaves as follows: ________________________________________________________________ ... | TAIL . HEAD | PAGE | PAGE | TAIL . HEAD | ... _____|_combined page A_|________|________|_combined page B_|____ 1 ] -> [ 2 ] -> [ 3 If the above three reads are requested in the order 1-2-3, it will generate a large work chain rather than 3 individual work chains to reduce scheduling overhead and boost up sequential read. However, if Read 2 is processed slightly earlier than Read 1, currently it still generates 2 individual work chains (chain 1, 2) but it does in-place decompression for combined page A, moreover, if chain 2 decompresses ahead of chain 1, it will be a race and lead to corrupted decompressed page. This patch fixes it.

2019-02-27staging: erofs: fix illegal address access under memory pressureGao Xiang1-1/+6
Considering a read request with two decompressed file pages, If a decompression work cannot be started on the previous page due to memory pressure but in-memory LTP map lookup is done, builder->work should be still NULL. Moreover, if the current page also belongs to the same map, it won't try to start the decompression work again and then run into trouble. This patch aims to solve the above issue only with little changes as much as possible in order to make the fix backport easier. kernel message is: <4>[1051408.015930s]SLUB: Unable to allocate memory on node -1, gfp=0x2408040(GFP_NOFS|__GFP_ZERO) <4>[1051408.015930s] cache: erofs_compress, object size: 144, buffer size: 144, default order: 0, min order: 0 <4>[1051408.015930s] node 0: slabs: 98, objs: 2744, free: 0 * Cannot allocate the decompression work <3>[1051408.015960s]erofs: z_erofs_vle_normalaccess_readpages, readahead error at page 1008 of nid 5391488 * Note that the previous page was failed to read <0>[1051408.015960s]Internal error: Accessing user space memory outside uaccess.h routines: 96000005 [#1] PREEMPT SMP ... <4>[1051408.015991s]Hardware name: kirin710 (DT) ... <4>[1051408.016021s]PC is at z_erofs_vle_work_add_page+0xa0/0x17c <4>[1051408.016021s]LR is at z_erofs_do_read_page+0x12c/0xcf0 ... <4>[1051408.018096s][<ffffff80c6fb0fd4>] z_erofs_vle_work_add_page+0xa0/0x17c <4>[1051408.018096s][<ffffff80c6fb3814>] z_erofs_vle_normalaccess_readpages+0x1a0/0x37c <4>[1051408.018096s][<ffffff80c6d670b8>] read_pages+0x70/0x190 <4>[1051408.018127s][<ffffff80c6d6736c>] __do_page_cache_readahead+0x194/0x1a8 <4>[1051408.018127s][<ffffff80c6d59318>] filemap_fault+0x398/0x684 <4>[1051408.018127s][<ffffff80c6d8a9e0>] __do_fault+0x8c/0x138 <4>[1051408.018127s][<ffffff80c6d8f90c>] handle_pte_fault+0x730/0xb7c <4>[1051408.018127s][<ffffff80c6d8fe04>] __handle_mm_fault+0xac/0xf4 <4>[1051408.018157s][<ffffff80c6d8fec8>] handle_mm_fault+0x7c/0x118 <4>[1051408.018157s][<ffffff80c8c52998>] do_page_fault+0x354/0x474 <4>[1051408.018157s][<ffffff80c8c52af8>] do_translation_fault+0x40/0x48 <4>[1051408.018157s][<ffffff80c6c002f4>] do_mem_abort+0x80/0x100 <4>[1051408.018310s]---[ end trace 9f4009a3283bd78b ]--- Fixes: 3883a79abd02 ("staging: erofs: introduce VLE decompression support") Cc: <stable@vger.kernel.org> # 4.19+ Signed-off-by: Gao Xiang <gaoxiang25@huawei.com> Reviewed-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
