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.

Roopa Prabhu authored
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:

David Ahern authored
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:

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 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.

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:

We already build the swiotlb code for 32-bit kernels with PAE support, but the code to actually use swiotlb has only been enabled for 64-bit kernels for an unknown reason. Before Linux v4.18 we paper over this fact because the networking code, the SCSI layer and some random block drivers implemented their own bounce buffering scheme. [ mingo: Changelog fixes. ] Fixes: 21e07dba ("scsi: reduce use of block bounce buffers") Fixes: ab74cfeb ("net: remove the PCI_DMA_BUS_IS_PHYS check in illegal_highdma") Reported-by:

Commit 058214a4 ("ip6_tun: Add infrastructure for doing encapsulation") added the ip6_tnl_encap() call in ip6_tnl_xmit(), before the call to ipv6_push_frag_opts() to append the IPv6 Tunnel Encapsulation Limit option (option 4, RFC 2473, par. 5.1) to the outer IPv6 header. As long as the option didn't actually end up in generated packets, this wasn't an issue. Then commit 89a23c8b ("ip6_tunnel: Fix missing tunnel encapsulation limit option") fixed sending of this option, and the resulting layout, e.g. for FoU, is: .-------------------.------------.----------.-------------------.----- - - | Outer IPv6 Header | UDP header | Option 4 | Inner IPv6 Header | Payload '-------------------'------------'----------'-------------------'----- - - Needless to say, FoU and GUE (at least) won't work over IPv6. The option is appended by default, and I couldn't find a way to disable it with the current iproute2. Turn this into a more reasonable: .-------------------.----------.------------.-------------------.----- - - | Outer IPv6 Header | Option 4 | UDP header | Inner IPv6 Header | Payload '-------------------'----------'------------'-------------------'----- - - With this, and with 84dad559 ("udp6: fix encap return code for resubmitting"), FoU and GUE work again over IPv6.

In ethtool_ioctl(), the ioctl command 'ethcmd' is checked through a switch statement to see whether it is necessary to pre-process the ethtool structure, because, as mentioned in the comment, the structure ethtool_rxnfc is defined with padding. If yes, a user-space buffer 'rxnfc' is allocated through compat_alloc_user_space(). One thing to note here is that, if 'ethcmd' is ETHTOOL_GRXCLSRLALL, the size of the buffer 'rxnfc' is partially determined by 'rule_cnt', which is actually acquired from the user-space buffer 'compat_rxnfc', i.e., 'compat_rxnfc->rule_cnt', through get_user(). After 'rxnfc' is allocated, the data in the original user-space buffer 'compat_rxnfc' is then copied to 'rxnfc' through copy_in_user(), including the 'rule_cnt' field. However, after this copy, no check is re-enforced on 'rxnfc->rule_cnt'. So it is possible that a malicious user race to change the value in the 'compat_rxnfc->rule_cnt' between these two copies. Through this way, the attacker can bypass the previous check on 'rule_cnt' and inject malicious data. This can cause undefined behavior of the kernel and introduce potential security risk. This patch avoids the above issue via copying the value acquired by get_user() to 'rxnfc->rule_cn', if 'ethcmd' is ETHTOOL_GRXCLSRLALL. Signed-off-by:
