[ Upstream commit 0066f623bce8f98b69b752ee03d46a5047c281b8 ]
Prefer to report ENOMEM rather than incur the oom for allocations in
ksmbd. __GFP_NORETRY could not achieve that, It would fail the allocations
just too easily. __GFP_RETRY_MAYFAIL will keep retrying the allocation
until there is no more progress and fail the allocation instead go OOM
and let the caller to deal with it.

move asm/unaligned.h to linux/unaligned.h2024-10-02T21:23:23+00:00Al Viroviro@zeniv.linux.org.uk2024-10-01T19:35:57+00:00urn:sha1:5f60d5f6bbc12e782fac78110b0ee62698f3b576
asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

ksmbd: add support for surrogate pair conversion2023-10-23T00:06:27+00:00Namjae Jeonlinkinjeon@kernel.org2023-10-21T12:01:20+00:00urn:sha1:0c180317c654a494fe429adbf7bc9b0793caf9e2
ksmbd is missing supporting to convert filename included surrogate pair
characters. It triggers a "file or folder does not exist" error in
Windows client.
[Steps to Reproduce for bug]
1. Create surrogate pair file
touch $(echo -e '\xf0\x9d\x9f\xa3')
touch $(echo -e '\xf0\x9d\x9f\xa4')
2. Try to open these files in ksmbd share through Windows client.
This patch update unicode functions not to consider about surrogate pair
(and IVS).

fs/smb: Swing unicode common code from smb->NLS2023-08-30T13:55:51+00:00Dr. David Alan Gilbertlinux@treblig.org2023-08-17T00:22:30+00:00urn:sha1:089f7f591348ca3325639f541fa4f78d9540dab5
Swing most of the inline functions and unicode tables into nls
from the copy in smb/server. This is UCS-2 rather than most
of the rest of the code in NLS, but it currently seems like the
best place for it.
The actual unicode.c implementations vary much more between server
and client so they're unmoved.

smb: move client and server files to common directory fs/smb2023-05-24T21:29:21+00:00Steve Frenchstfrench@microsoft.com2023-05-22T01:46:30+00:00urn:sha1:38c8a9a52082579090e34c033d439ed2cd1a462d
Move CIFS/SMB3 related client and server files (cifs.ko and ksmbd.ko
and helper modules) to new fs/smb subdirectory:
fs/cifs --> fs/smb/client
fs/ksmbd --> fs/smb/server
fs/smbfs_common --> fs/smb/common
