Code of Conduct Interpretation: Add document explaining how the Code of 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. Co-Developed-by:

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.

We're only setting up the bounce bio sets if we happen to need bouncing for regular HIGHMEM, not if we only need it for ISA devices. Protect the ISA bounce setup with a mutex, since it's being invoked from driver init functions and can thus be called in parallel. Cc: stable@vger.kernel.org Reported-by:

This reverts commit 8e326289. 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. Signed-off-by:

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. Fixes: 502a2ffd ("ipv6: convert idev_list to list macros") Signed-off-by:

When submitting a bio, multiple recursive calls to make_request() may occur. This causes the initial associate done in blkcg_bio_issue_check() to be incorrect and reference the prior request_queue. This introduces a helper to do reassociation when make_request() is recursively called. Fixes: a7b39b4e ("blkcg: always associate a bio with a blkg") Reported-by:

Dimitris Michailidis authored
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 88078d98 ("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(). Fixes: 88078d98 ("net: pskb_trim_rcsum() and CHECKSUM_COMPLETE are friends") Signed-off-by:

Fix synthetic event to accept unsigned modifier for its field type correctly. Currently, synthetic_events interface returns error for "unsigned" modifiers as below; # echo "myevent unsigned long var" >> synthetic_events sh: write error: Invalid argument This is because argv_split() breaks "unsigned long" into "unsigned" and "long", but parse_synth_field() doesn't expected it. With this fix, synthetic_events can handle the "unsigned long" correctly like as below; # echo "myevent unsigned long var" >> synthetic_events # cat synthetic_events myevent unsigned long var Link: http://lkml.kernel.org/r/153986832571.18251.8448135724590496531.stgit@devbox Cc: Shuah Khan <shuah@kernel.org> Cc: Tom Zanussi <tom.zanussi@linux.intel.com> Cc: stable@vger.kernel.org Fixes: commit 4b147936 ("tracing: Add support for 'synthetic' events") Signed-off-by:

enable_smccc_arch_workaround_1() passes NULL as the hyp_vecs start and end if the HVC conduit is in use, and ARM_SMCCC_ARCH_WORKAROUND_1 is detected. If the guest kernel happened to be built with KVM_INDIRECT_VECTORS, we go on to allocate a slot, memcpy() the empty workaround in and do the appropriate cache maintenance. This works as we always tell memcpy() the range is 0, so it never accesses the NULL src pointer, but we still do the cache maintenance. If hyp_vecs_start is NULL we know we're a guest, just update the fn like the !KVM_INDIRECT_VECTORS version. Reviewed-by:

IP transports will most likely use the same controller options matching when detecting a duplicate connect. Move it to fabrics. Signed-off-by:

If not passed, we set the default trsvcid. We can rely on having trsvcid and can simplify the controller matching logic. Signed-off-by:

The calculated ideal rate can easily overflow an unsigned long, thus making the best div selection buggy as soon as no ideal match is found before the overflow occurs. Fixes: 4731a72d ("drm/sun4i: request exact rates to our parents") Cc: <stable@vger.kernel.org> Signed-off-by:
