smb3: fix setting SecurityFlags when encryption is required

2024-08-14T11:52:59+00:00

commit 1b5487aefb1ce7a6b1f15a33297d1231306b4122 upstream. Setting encryption as required in security flags was broken. For example (to require all mounts to be encrypted by setting): "echo 0x400c5 > /proc/fs/cifs/SecurityFlags" Would return "Invalid argument" and log "Unsupported security flags" This patch fixes that (e.g. allowing overriding the default for SecurityFlags 0x00c5, including 0x40000 to require seal, ie SMB3.1.1 encryption) so now that works and forces encryption on subsequent mounts.

cifs: fix setting SecurityFlags to true

2024-07-18T11:18:37+00:00

commit d2346e2836318a227057ed41061114cbebee5d2a upstream. If you try to set /proc/fs/cifs/SecurityFlags to 1 it will set them to CIFSSEC_MUST_NTLMV2 which no longer is relevant (the less secure ones like lanman have been removed from cifs.ko) and is also missing some flags (like for signing and encryption) and can even cause mount to fail, so change this to set it to Kerberos in this case. Also change the description of the SecurityFlags to remove mention of flags which are no longer supported.

Replace HTTP links with HTTPS ones: CIFS

2020-07-05T20:23:38+00:00

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

docs: fs: cifs: convert to ReST and add to admin-guide book

2019-07-31T20:13:42+00:00

The filenames for cifs documentation is not using the same convention as almost all Kernel documents is using. So, rename them to a more appropriate name. Then, manually convert the documentation files for CIFS to ReST. By doing a manual conversion, we can preserve the original author's style, while making it to look more like the other Kernel documents. Most of the conversion here is trivial. The most complex one was the README file (which was renamed to usage.rst). Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Jonathan Corbet
