2018-10-24selftests/ftrace: Remove unneeded per-test init/cleanup ftraceMasami Hiramatsu44-378/+1
Since ftracetest framework calls initialize_ftrace() right before each test and after all tests, we don't need to init/cleanup ftrace for each test case.

2018-10-24selftests/ftrace: Add --console hidden optionMasami Hiramatsu1-1/+13
Add --console hidden option for debug test cases. This option allows to put "sh" or something else when the test case hits a bug.

2018-10-22Code of Conduct Interpretation: Add document explaining how the Code of ↵Greg Kroah-Hartman2-0/+154
Conduct is to be interpreted The Contributor Covenant Code of Conduct is a general document meant to provide a set of rules for almost any open source community. Every open-source community is unique and the Linux kernel is no exception. Because of this, this document describes how we in the Linux kernel community will interpret it. We also do not expect this interpretation to be static over time, and will adjust it as needed. This document was created with the input and feedback of the TAB as well as many current kernel maintainers.

2018-10-22Code of conduct: Fix wording around maintainers enforcing the code of conductChris Mason1-4/+0
As it was originally worded, this paragraph requires maintainers to enforce the code of conduct, or face potential repercussions. It sends the wrong message, when really we just want maintainers to be part of the solution and not violate the code of conduct themselves. Removing it doesn't limit our ability to enforce the code of conduct, and we can still encourage maintainers to help maintain high standards for the level of discourse in their subsystem.

2018-10-20Revert "neighbour: force neigh_invalidate when NUD_FAILED update is from admin"Roopa Prabhu1-2/+1
This reverts commit 8e326289e3069dfc9fa9c209924668dd031ab8ef. This patch results in unnecessary netlink notification when one tries to delete a neigh entry already in NUD_FAILED state. Found this with a buggy app that tries to delete a NUD_FAILED entry repeatedly. While the notification issue can be fixed with more checks, adding more complexity here seems unnecessary. Also, recent tests with other changes in the neighbour code have shown that the INCOMPLETE and PROBE checks are good enough for the original issue.

2018-10-20net/ipv6: Fix index counter for unicast addresses in in6_dump_addrsDavid Ahern1-2/+4
The loop wants to skip previously dumped addresses, so loops until current index >= saved index. If the message fills it wants to save the index for the next address to dump - ie., the one that did not fit in the current message. Currently, it is incrementing the index counter before comparing to the saved index, and then the saved index is off by 1 - it assumes the current address is going to fit in the message. Change the index handling to increment only after a succesful dump.

2018-10-20net: fix pskb_trim_rcsum_slow() with odd trim offsetDimitris Michailidis1-2/+3
We've been getting checksum errors involving small UDP packets, usually 59B packets with 1 extra non-zero padding byte. netdev_rx_csum_fault() has been complaining that HW is providing bad checksums. Turns out the problem is in pskb_trim_rcsum_slow(), introduced in commit 88078d98d1bb ("net: pskb_trim_rcsum() and CHECKSUM_COMPLETE are friends"). The source of the problem is that when the bytes we are trimming start at an odd address, as in the case of the 1 padding byte above, skb_checksum() returns a byte-swapped value. We cannot just combine this with skb->csum using csum_sub(). We need to use csum_block_sub() here that takes into account the parity of the start address and handles the swapping. Matches existing code in __skb_postpull_rcsum() and esp_remove_trailer().

2018-10-19tracing: Fix synthetic event to allow semicolon at endMasami Hiramatsu1-1/+1
Fix synthetic event to allow independent semicolon at end. The synthetic_events interface accepts a semicolon after the last word if there is no space. # echo "myevent u64 var;" >> synthetic_events But if there is a space, it returns an error. # echo "myevent u64 var ;" > synthetic_events sh: write error: Invalid argument This behavior is difficult for users to understand. Let's allow the last independent semicolon too.
