caif: fix cfv_netdev_tx()'s return type

2020-06-29T03:52:53+00:00

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t', which is a typedef for an enum type, but the implementation in this driver returns an 'int'. Fix this by returning 'netdev_tx_t' in this driver too. Signed-off-by: Luc Van Oostenryck Signed-off-by: David S. Miller

Fix this by returning 'netdev_tx_t' in this driver too and returning NETDEV_TX_OK instead of 0 accordingly. Signed-off-by: Luc Van Oostenryck Signed-off-by: David S. Miller

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

vhost: revert "vhost: disable for OABI"

2020-06-02T06:45:13+00:00

This reverts commit d085eb8ce727 ("vhost: disable for OABI") With commit "virtio: force spec specified alignment on types" in place, we force proper alignment for all structures, so there's no longer a reason to blacklist OABI. Signed-off-by: Michael S. Tsirkin

vhost: disable for OABI

2020-04-20T14:19:22+00:00

vhost is currently broken on the some ARM configs. The reason is that the ring element addresses are passed between components with different alignments assumptions. Thus, if guest selects a pointer and host then gets and dereferences it, then alignment assumed by the host's compiler might be greater than the actual alignment of the pointer. compiler on the host from assuming pointer is aligned. This actually triggers on ARM with -mabi=apcs-gnu - which is a deprecated configuration. With this OABI, compiler assumes that all structures are 4 byte aligned - which is stronger than virtio guarantees for available and used rings, which are merely 2 bytes. Thus a guest without -mabi=apcs-gnu running on top of host with -mabi=apcs-gnu will be broken. The correct fix is to force alignment of structures - however that is an intrusive fix that's best deferred until the next release. We didn't previously support such ancient systems at all - this surfaced after vdpa support prompted removing dependency of vhost on VIRTULIZATION. So for now, let's just add something along the lines of depends on !ARM || AEABI to the virtio Kconfig declaration, and add a comment that it has to do with struct member alignment. Note: we can't make VHOST and VHOST_RING themselves have a dependency since these are selected. Add a new symbol for that. We should be able to drop this dependency down the road.
