Pull iov_iter updates from Al Viro: "iov_iter work; most of that is about getting rid of direction misannotations and (hopefully) preventing more of the same for the future" * tag 'pull-iov_iter' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: use less confusing names for iov_iter direction initializers iov_iter: saner checks for attempt to copy to/from iterator [xen] fix "direction" argument of iov_iter_kvec() [vhost] fix 'direction' argument of iov_iter_{init,bvec}() [target] fix iov_iter_bvec() "direction" argument [s390] memcpy_real(): WRITE is "data source", not destination...

Bluetooth: 6LoWPAN: add missing hci_dev_put() in get_l2cap_conn()

2022-12-02T21:09:30+00:00

hci_get_route() takes reference, we should use hci_dev_put() to release it when not need anymore. Fixes: 6b8d4a6a0314 ("Bluetooth: 6LoWPAN: Use connected oriented channel instead of fixed one") Signed-off-by: Wang ShaoBo Signed-off-by: Luiz Augusto von Dentz

use less confusing names for iov_iter direction initializers

2022-11-25T18:01:55+00:00

READ/WRITE proved to be actively confusing - the meanings are "data destination, as used with read(2)" and "data source, as used with write(2)", but people keep interpreting those as "we read data from it" and "we write data to it", i.e. exactly the wrong way. Call them ITER_DEST and ITER_SOURCE - at least that is harder to misinterpret... Signed-off-by: Al Viro

bluetooth: Use netif_rx().

2022-03-07T11:40:41+00:00

Since commit baebdf48c3600 ("net: dev: Makes sure netif_rx() can be invoked in any context.") the function netif_rx() can be used in preemptible/thread context as well as in interrupt context. Use netif_rx(). Cc: Marcel Holtmann Cc: Johan Hedberg Cc: Luiz Augusto von Dentz Cc: linux-bluetooth@vger.kernel.org Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: David S. Miller

Bluetooth: 6lowpan: No need to clear memory twice

2022-03-04T15:10:49+00:00

'peer_addr' is a structure embedded in 'struct lowpan_peer'. So there is no need to explicitly call memset(0) on it. It is already zeroed by kzalloc() when 'peer' is allocated. Signed-off-by: Christophe JAILLET Signed-off-by: Marcel Holtmann

bluetooth: use dev_addr_set()

2021-10-25T18:01:29+00:00

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it go through appropriate helpers. Reviewed-by: Marcel Holtmann Acked-by: Marcel Holtmann Signed-off-by: Jakub Kicinski

Bluetooth: 6lowpan: Use the correct print format

2021-06-26T05:12:41+00:00

According to Documentation/core-api/printk-formats.rst, Use the correct print format. Printing an unsigned int value should use %u instead of %d. Otherwise printk() might end up displaying negative numbers. Signed-off-by: Kai Ye Signed-off-by: Marcel Holtmann
