net: use skb_queue_empty_lockless() in poll() handlers

2019-10-28T20:33:41Z

Many poll() handlers are lockless. Using skb_queue_empty_lockless() instead of skb_queue_empty() is more appropriate. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 194

2019-05-30T18:29:22Z

Based on 1 normalized pattern(s): license terms gnu general public license gpl version 2 extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 161 file(s).

Merge tag 'spdx-5.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2019-05-21T19:33:38Z

Pull SPDX update from Greg KH: "Here is a series of patches that add SPDX tags to different kernel files, based on two different things: - SPDX entries are added to a bunch of files that we missed a year ago that do not have any license information at all. These were either missed because the tool saw the MODULE_LICENSE() tag, or some EXPORT_SYMBOL tags, and got confused and thought the file had a real license, or the files have been added since the last big sweep, or they were Makefile/Kconfig files, which we didn't touch last time. - Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan tools can determine the license text in the file itself. Where this happens, the license text is removed, in order to cut down on the 700+ different ways we have in the kernel today, in a quest to get rid of all of these. These patches have been out for review on the linux-spdx@vger mailing list, and while they were created by automatic tools, they were hand-verified by a bunch of different people, all whom names are on the patches are reviewers. The reason for these "large" patches is if we were to continue to progress at the current rate of change in the kernel, adding license tags to individual files in different subsystems, we would be finished in about 10 years at the earliest. There will be more series of these types of patches coming over the next few weeks as the tools and reviewers crunch through the more "odd" variants of how to say "GPLv2" that developers have come up with over the years, combined with other fun oddities (GPL + a BSD disclaimer?) that are being unearthed, with the goal for the whole kernel to be cleaned up. These diffstats are not small, 3840 files are touched, over 10k lines removed in just 24 patches" * tag 'spdx-5.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (24 commits) treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 25 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 24 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 23 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 22 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 21 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 20 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 19 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 18 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 17 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 15 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 14 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 13 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 12 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 11 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 10 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 9 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 7 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 5 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 4 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 3 ...

net: caif: avoid using qdisc_qlen()

2019-04-10T19:20:46Z

Such helper does not cope correctly with NOLOCK qdiscs. In the following patches we will move back qlen to per CPU values for such qdiscs, so qdisc_qlen_sum() is not an option, too. Instead, use qlen only for lock qdiscs, and always set flow off for NOLOCK qdiscs with a not empty tx queue. Signed-off-by: Paolo Abeni Signed-off-by: David S. Miller

net: caif: use skb helpers instead of open-coding them

2019-02-17T19:01:17Z

Use existing skb_put_data() and skb_trim() instead of open-coding them, with the skb_put_data() first so that logically, `skb` still contains the data to be copied in its data..tail area when skb_put_data() reads it. This change on its own is a cleanup, and it is also necessary for potential future integration of skbuffs with things like KASAN. Signed-off-by: Jann Horn Signed-off-by: David S. Miller

Revert "net: simplify sock_poll_wait"

2018-10-23T17:57:06Z

This reverts commit dd979b4df817e9976f18fb6f9d134d6bc4a3c317. This broke tcp_poll for SMC fallback: An AF_SMC socket establishes an internal TCP socket for the initial handshake with the remote peer. Whenever the SMC connection can not be established this TCP socket is used as a fallback. All socket operations on the SMC socket are then forwarded to the TCP socket. In case of poll, the file->private_data pointer references the SMC socket because the TCP socket has no file assigned. This causes tcp_poll to wait on the wrong socket.

net: caif: remove redundant null check on frontpkt

2018-09-18T01:49:57Z

It is impossible for frontpkt to be null at the point of the null check because it has been assigned from rearpkt and there is no way rearpkt can be null at the point of the assignment because of the sanity checking and exit paths taken previously. Remove the redundant null check. Detected by CoverityScan, CID#114434 ("Logically dead code") Signed-off-by: Colin Ian King Signed-off-by: David S. Miller
