treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21Z

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

net: nfc: fix bounds checking bugs on "pipe"

2020-03-06T05:32:42Z

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 commands

2018-09-19T02:55:01Z

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. Cc: Samuel Ortiz Cc: Allen Pais Cc: "David S.
