* treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada2020-06-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
* net: nfc: fix bounds checking bugs on "pipe"Dan Carpenter2020-03-051-3/+16
| | | | | | | | | | | | | | | This is similar to commit 674d9de02aa7 ("NFC: Fix possible memory corruption when handling SHDLC I-Frame commands") and commit d7ee81ad09f0 ("NFC: nci: Add some bounds checking in nci_hci_cmd_received()") which added range checks on "pipe". The "pipe" variable comes skb->data[0] in nfc_hci_msg_rx_work(). It's in the 0-255 range. We're using it as the array index into the hdev->pipes[] array which has NFC_HCI_MAX_PIPES (128) members.

* NFC: Fix possible memory corruption when handling SHDLC I-Frame commandsSuren Baghdasaryan2018-09-181-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | When handling SHDLC I-Frame commands "pipe" field used for indexing into an array should be checked before usage. If left unchecked it might access memory outside of the array of size NFC_HCI_MAX_PIPES(127). Malformed NFC HCI frames could be injected by a malicious NFC device communicating with the device being attacked (remote attack vector), or even by an attacker with physical access to the I2C bus such that they could influence the data transfers on that bus (local attack vector). skb->data is controlled by the attacker and has only been sanitized in the most trivial ways (CRC check), therefore we can consider the create_info struct and all of its members to tainted. 'create_info->pipe' with max value of 255 (uint8) is used to take an offset of the hdev->pipes array of 127 elements which can lead to OOB write.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Joe and Bjørn suggested that it'd be nicer to not have the cast in the fairly common case of doing *(u8 *)skb_put(skb, 1) = c; Add skb_put_u8() for this case, and use it across the code, using the following spatch: @@ expression SKB, C, S; typedef u8; identifier fn = {skb_put}; fresh identifier fn2 = fn ## "_u8"; @@ - *(u8 *)fn(SKB, S) = C; + fn2(SKB, C); Note that due to the "S", the spatch isn't perfect, it should have checked that S is 1, but there's also places that use a sizeof expression like sizeof(var) or sizeof(u8) etc. Turns out that nobody ever did something like *(u8 *)skb_put(skb, 2) = c; which would be wrong anyway since the second byte wouldn't be initialized.

* NFC: Changed event_received hci ops result semanticEric Lapuyade2013-01-101-6/+8
| | | | | | | | | | | | | Some chips use a standard HCI event code, destined to a proprietary gate, with a different meaning. Therefore, the HCI driver must always have a chance to intercept the event before standard processing is attempted. The new semantic specifies that the result value "1" means that the driver doesn't especially handle the event. result <= 0 means it was handled.

* NFC: Added error handling in event_received hci opsEric Lapuyade2013-01-101-3/+5

* NFC: Fixed nfc core and hci unregistration and cleanupEric Lapuyade2013-01-102-7/+31
| | | | | | | | | | When an adapter is removed, it will unregister itself from hci and/or nfc core. In order to do that safely, work tasks must first be canceled and prevented to be scheduled again, before the hci or nfc device can be destroyed.
